    AUTOMATIC SLIME WATER CONCENTRATION SYSTEM WITH CONCENTRATIONDETECTION FUNCTION
    TECHNICAL FIELD The present invention belongs to the technical field of slime water treatment, and particularly relates to an automatic slime water concentration system with a concentration detection function.
    BACKGROUND Coal is the main energy in China, accounting for more than 70% of primary energy consumption. For a long period of time, the status of coal as the main energy source will not change. Due to the geological structure and mining methods, a large amount of gangue is inevitably mixed after coal mining. This gangue has high ash content, high sulfur content and low calorific value, which greatly adversely affects the clean utilization of coal. At present, the main solution is coal separation. The main separation method of traditional coal is wet separation, and the coal preparation method is divided into desliming selection and non-desliming selection according to whether desliming is performed before selection. No matter which way is adopted, the treatment of slime water in coal preparation plant is a big problem in coal preparation plant production, and even becomes an obstacle to improve quality and increase efficiency in coal preparation plant. The treatment of slime water in coal preparation plant mainly includes five stages: classification concentration, separation, desliming dehydration, sedimentation and filtration dehydration. In the above stages, due to the fine particle size of the coal slime, the sedimentation process is affected by buoyancy, mutual collision resistance, gravity and water impact force, and its sedimentation process is complex and slow, so it is usually necessary to build a large concentration tank as equipment for coal slime sedimentation, so the effect of thecoal slime sedimentation is a key factor to measure the working efficiency of the automatic concentration system for coal slime water treatment. As the slime water gradually settles to the bottom of the concentration tank, it is necessary to monitor the settling speed during the settling process, and determine the dosage of the coagulant and flocculant according to the settling speed, and the settling speed can be fed back through the concentration at different heights. Ultrasonic interface instrument is mostly used in traditional detection to detect the concentration of slime water. The ultrasonic interface instrument requires a clear interface between solid and liquid, which leads to inaccurate and large errors in monitoring the sedimentation effect of the coal slime in the concentration tank by the existing detection methods, and brings many troubles to actual detection work. At the same time, even if the concentration of coal slime water is determined, it is still necessary to add chemicals through independent chemicals feeding equipment, and the whole adding process is extremely time-consuming and laborious, which obviously cannot meet the needs of modern production enterprises.
    SUMMARY The purpose of the present invention is to overcome the shortcomings of the prior art, and provide an automatic slime water concentration system with a reasonable and compact structure and a concentration detection function, which can automatically and quickly add flocculants, coagulants and even slime water in a concentration tank by monitoring the real-time weights of slime water samples taken at different heights, so as to ensure that the sedimentation effect of the slime water in the concentration tank always tends to be within an optimal range, and the reagent addition accuracy is high and the system has good working stability, which is extremely suitable for modern production enterprises which require fast pace, high efficiency and automation at present.
    In order to achieve the above purpose, the invention adopts the following technical solution: An automatic slime water concentration system with concentration detection function comprises a concentration tank; wherein, the slime water concentration system further comprises a weight detection component, the weight detection component comprises a slime water feeding pipe, a sampling pipe and a slime water discharging pipe which are sequentially arranged along a slime water traveling path; the slime water feeding pipe is communicated with the concentration tank, and both ends of the sampling pipe are respectively fixedly connected and communicated with the slime water feeding pipe and the slime water discharging pipe through a flexible connecting pipe; the weight detection component also comprises a weighing sensor for weighing a real-time weight of the sampling pipe and a drainage valve or a drainage pump for timely discharging weighed slime water in the sampling pipe; there are more than two sets of the weight detection component arranged in sequence along a height direction of the concentration tank; the automatic slime water concentration system further comprises a flocculant dosing component and a coagulant dosing component; the flocculant dosing component and the coagulant dosing component both comprise a dosing and stirring barrel, and medicines or medicinal powders enter a cavity of the dosing and stirring barrel through a medicine feeder and a feeding conveyor belt at a medicine storage part in sequence; a water inlet pipe for feeding water and a stirring component for mixing medicines in the cavity of the stirring barrel are also arranged at the dosing and stirring barrel; medicine outlet pipes of the dosing and stirring barrel of the flocculant dosing component and the coagulant dosing component are communicated with an slime water inlet and then communicated to the concentration tank, and a medicine discharge pump is arranged at the medicine outlet pipe; the stirring component comprises a stirring motor, a power output shaft of the stirring motor extends vertically downwards and a stirring blade is arranged on the power output shaft; each set of stirring blades comprises an upper blade plate and a lower blade plate which are arranged in parallel with each other, and an inclined cotyledon plate is convexly arranged at a lower plate surface of the upper blade plate in the direction of the lower blade plate; the inclined cotyledon board and the upper blade plate have an included angle layout, and there is a distance between the inclined cotyledon board and the lower blade plate in the height direction; The automatic slime water concentration system further comprises a PLC master control module, a weight measurement monitoring PLC sub-module for monitoring a weight measurement component, and a flocculant monitoring PLC sub-module for monitoring the flocculant dosing component, and a coagulant monitoring PLC sub-
    module for monitoring the coagulant dosing component; wherein, the weight measurement monitoring PLC sub-module is used to summarize data of slime water concentration at different heights in the concentration tank and send the data to the PLC master control module; after processing the summarized data, the PLC master control module sends information to the flocculant monitoring PLC sub-module and the coagulant monitoring PLC sub-module to control a medicine discharge pump to complete addition of flocculant mixed solution and coagulant mixed solution into the concentration tank . Preferably, the stirring blades present a curved and twisted structure bent upward or downward as a whole, and in the height direction, more than one group of adjacent stirring blades is taken as one group of stirring layers, and the bending directions of the stirring blades (46) of two adjacent groups of stirring layers are opposite to each other.
    Preferably, the slime water feeding pipe of the weight detection component located at the highest position is communicated with overflow weir of the concentration tank.
    Preferably, the flexible connecting pipe is a corrugated hose, the sampling pipe is fixedly connected with a connecting rod, and the connecting rod extends vertically upward and is fixedly connected with a sensing end of the weighing sensor.
    Preferably, the drainage valve is an electromagnetic valve, and the slime water discharge pipe is communicated with the slime water inlet of the concentration tank.
    Preferably, a weight sensor for monitoring the weight of a medicament or powder on an upper belt surface is arranged at the feeding conveyor belt.
    Preferably, a water inlet solenoid valve with pipeline opening and closing function is arranged on the water inlet pipe.
    Preferably, a liquid level meter for detecting a liquid level in the barrel cavity is arranged at the dosing and stirring barre.
    The method has the beneficial effects that: 1) according to that present invention, the weight detection components are arrange at different heights on the side surface of the concentration tank, so that slime water with different heights can be taken out from the concentration tank body respectively. Taking one of them as an example, the slime water enters one of the sampling pipes through the flexible connecting pipe, and the weight of the slime water samples taken at different heights above and below the concentration tank can be obtained by the weighing sensor; since the concentration of the slime water samples 5 below is higher than above, the weight measured below is greater than above. After the weight is obtained, the concentration of the slime water at the current height can be obtained by calculation, and then the dosage of the coagulant and flocculant to be added can be calculated. The slime water in the sampling tube can be timely updated by the drainage valve or pump, so that the real-time monitoring of the real-time weight of the slime water samples taken at different heights can be realized, and then the real-time concentration of slime water at different heights can be obtained. The detection process is simple and fast, and the detection result is highly reliable, accurate and stable. Furthermore, the automatic coal slurry concentration system is additionally provided with a flocculant dosing component and a coagulant dosing component; in this way, once the concentration of the slime water at different heights in the concentration tank is detected, the dosage of coagulant and flocculant that need to be added can be calculated, then the corresponding PLC module can control the feeding of chemicals into the dosing and stirring barrel, and then the coagulant, flocculant and slime water are mixed and then enter the concentration tank together, so that the automatic reagent adding operation can be realized, and finally the best slime settling effect can be obtained, which is extremely suitable for modern manufacturers requiring fast rhythm and high efficiency.
    In addition, because the concentration detection in the concentration tank is real- time, the addition of flocculant and coagulant should also be real-time and there should be no delay; obviously, the design of the stirring blade is the key to the dosing and stirring barrel, and it must be able to get the water and the corresponding medicine in the first time to quickly achieve the purpose of mixing and stirring. On the one hand, the stirring blade itself is formed by matching the upper blade plate and the lower blade plate, and is matched with the inclined cotyledon plate, which is more conducive to the formation of turbulence effect, so that water and corresponding medicament can be mixed and stirred more quickly; on the other hand, each layer of the stirring blades presents an upward or downward curved structure as a whole, and in the height direction, more than one group of adjacent stirring blades is taken as one group of stirring layers, and the bending directions of stirring blades of two adjacent groups of stirring layers are opposite to each other, which is more conducive to improving the actual stirring effect.
    2) Further, the slime water inlet pipe of the weight detection component located at the highest position is communicated with the overflow weir of the concentration tank, so that the concentration change of slime water at different heights can be more clearly confirmed, and the conversion result is more accurate. The flexible connecting pipe is a corrugated hose, and in actual use, the two ends of the sampling pipe can be directly fixed, or even the adjacent ends of the two groups of flexible connecting pipes can be extended oppositely and fixedly connected, and then the sampling pipe can be sheathed. On the one hand, the sampling pipe provides the slime water sample to accommodate the space, and on the other hand, it serves as a hard carrier for the installation and measurement of the sensing end of the weighing sensor, so as to ensure the stability and reliability of the actual work.
    3) Because the concentration of the slime water in the concentration tank changes in real time, by considering either taking an average value from multiple times of sampling, or the fact that the sample of slime water after detection does not interfere with the subsequent sampling, the detected slime water should directly flow back to the slime water inlet through the drain valve to ensure the accuracy of the subsequent detection data of the weight detection component.

    DESCRIPTION OF EMBODIMENTS For convenience of understanding, the specific structure and working mode of the present invention will be further described below with reference to Figs. 1-8. Referring to Figs. 1-8, the concrete structure of the present invention includes a concentration tank 10 with the concentration tank 10 as the core and provided with a weight detection component 20, a flocculant dosing component 40a and a coagulant dosing component 40b.Wherein: as shown in Figs. 2 and 4, the weight detection component 20 includes a slime water inlet pipe 21, a flexible connecting pipe 25, a sampling pipe 22 and a slime water outlet pipe 23 arranged in sequence. In actual assembly, the flexible connecting pipe 25 may be a separate soft pipe structure, such as a corrugated hose. The two ends of the flexible connecting pipe 25 are respectively fixed with the slime water inlet pipe 21 and the sampling pipe 22, and the slime water outlet pipe 23 and the sampling pipe 22, thereby forming a circulation channel of slime water samples. Of course, it is also possible to extend the adjacent ends of the two groups of flexible connecting pipes 25 towards each other to form an integrated structure, and the sampling pipe 22 is directly sleeved on the extended ends of the flexible connecting pipes 25, thus forming the structure shown in Fig. 3, which can also realize the sampling detection function of the sampling pipe 22. lt can be seen from the structure shown in Fig. 3 that a connecting rod 26 extends vertically upward from the outer wall of the sampling pipe 22, and the top end of the connecting rod 26 is fixedly connected with a weighing sensor 27 to obtain the weight of the slime water sample in the sampling pipe 22 in real time. After the sampling and weighing operation is completed, the slime water sample can be quickly discharged through the drain valve 24. If necessary, it may also be considered to add a controllable on-off valve or on-off pump at the slime water inlet pipe 21, so as to realize the functions of quantitatively pumping and weighing the slime water in the sampling pipe 22. At this time, a drainage pump is preferred to discharge the slime water samples in the sampling pipe 22 in a timely manner, so as to follow up and detect new slime water samples later. For the flocculant dosing component 40a and coagulant dosing component 40b, their specific structures are shown in Fig. 1 and Fig. 3-6. The flocculant dosing component 40a and the coagulant dosing component 40b both include a dosing and stirring barrel 41, and a medicine dosing component and a water dosing component are arranged at the barrel mouth of the dosing and stirring barrel 41. Wherein, the medicine dosing component includes a feeding conveyor belt 43, and a weight sensor 43a is arranged below the upper belt surface of the feeding conveyor belt 43, so as to timely monitor the weight of the medicine flowing out from the medicine feeder 42b, that is, the medicine storage part 42a; specifically, the belt surface of the feeding conveyor belt 43 may be arranged in the shape of a container, or a container for temporarily storing the medicine may be directly arranged at the upper belt surface of the feeding conveyor belt
    43. Of course, if the medicine powder is directly discharged from the medicine feeder 42Db, the structure can be as shown in Fig. 1 and Fig. 3, and the medicine powder can be directly discharged to the upper belt surface of the feeding conveyor belt 43. When the weight reaches the standard, the feeding conveyor belt 43 will drive the medicine forward until it is poured into the medicine dosing and stirring barrel 41. Considering the cleaning effect, a belt cleaner 43b may also be arranged at the feed conveyor belt 43, which will be discussed later. The water dosing component includes a water inlet pipe 44 and a water inlet solenoid valve 44a, so as to realize the rapid addition of water in the dosing and stirring barrel 41 in time. In order to ensure the liquid level in the dosing and stirring barrel 41, a liquid level meter 47 can be arranged for monitoring and corresponding management can be carried out through the PLC module.
    A stirring component is also arranged at the dosing and stirring barrel 41. As can be seen from Figs. 4-6, the stirring component includes a stirring motor 45, and the power output shaft of the stirring motor 45 extends vertically downward, and a stirring blade 46 is arranged on the power output shaft. Each set of stirring blades 486 includes an upper blade plate 46a and a lower blade plate 46b arranged in parallel with each other, and an inclined cotyledon plate 46¢ is convexly arranged at the lower surface of the upper blade plate 46a toward the lower blade plate 46b. The inclined cotyledon plate 46c has an included angle with the upper blade plate 46a, and there is a distance between the inclined cotyledon plate 46¢ and the lower blade plate 46b in the height direction. In order to ensure the stirring effect, the whole stirring blade 46 presents a curved and twisted structure bent upward or downward, and in the height direction, more than one group of adjacent stirring blades 46 is taken as one group of stirring layers, and the bending directions of the stirring blades 46 of the adjacent two groups of stirring layers are opposite to each other. The matching inclination degree of the inclined cotyledon plate 46¢ and the upper blade plate 46a can be seen in Fig. 7-8.
    In actual operation, on the basis of the above structure, the automatic operation function of the whole automatic slime water concentration system can be realized by adding PLC modules. Specifically, PLC modules can be divided into a PLC master control module a, a weight measurement monitoring PLC sub-module b for monitoring weight measurement component, a flocculant monitoring PLC sub-module c for monitoring flocculant dosing component 40a, and a coagulant monitoring PLC sub- module d for monitoring coagulant dosing component 40b. In operation, the weight measurement monitoring PLC sub-module b summarizes the data of the slime water concentration at different heights in the concentration tank 10 and sends it to the PLC master control module a. After processing the summarized data, the PLC master control module a sends the information to the flocculant monitoring PLC sub-module c and the coagulant monitoring PLC sub-module d, so that the flocculant and coagulant can be properly added to the concentration tank 10 through the medicine discharge pump e shown in Fig.4, and the automation degree can be significantly improved.
    Further, the actual detection flow of the slime water sample of the present invention includes the following algorithm steps: the slime water can be regarded as being constituted by water and slime, with the density of water being p1 and the density of slime being p:. the slime water samples are taken on site, and the samples are centrifuged at high speed in a laboratory centrifuge to obtain water samples and slime samples at the bottom, and measure their densities respectively to obtain ps and pz values; the volume v is known, and the correction of the volume v is generally completed by the first correction; the specific process is as follows: manually measuring the actual concentration in the sampling tube 22 at any group of weight detection components 20 through a measuring cylinder, an electronic scale, etc. and for convenience of sampling, usually taking the uppermost weight detection component 20; then, weighing the measured weight displayed at this time in the group of weight detection components 20, thereby obtaining the volume v of the actual slime water sample in any group of the weight detection components 20. The weight values in the sampling pipe 22 that can be obtained from top to bottom are x4, Xa, Xa, X4...... … and it is assumed that the concentration values to be obtained are my, mg, Ma, Ma... 5 through the following formula: xT=mi*vpi+{1-m1)*v*p: x2=mp'vipi+(1-m2) vip: X3=mz*v*'pi+{1-m3)*v'p2 X4=mg Vv pi+{1-m4)*v pz The actual values of m1, mz, ma, Mq......can be obtained.
    According to the obtained actual values of my, mz, ma, Ma......, the dosage of coagulant and flocculant to be added can be obtained by conventional calculation.
    After that, the flocculant dosing component 40a and coagulant dosing a component 40b can be operated, and the medicine discharge pump e is started to cooperate with the normal addition of the slime water at the slime water inlet 30, so as to finally realize the online change of the slime water concentration in the concentration tank 10 and the optimal adjustment of the sedimentation effect.
    Of course, the above is one of the specific embodiments of the present invention.
    In actual operation, the conventional structural modifications made under the premise of the structure of the present invention, for example, simply replacing the structure with the functions of the sampling pipe 22 and the flexible connecting pipe 25 in the weight detection component 20, replacing the electromagnetic valve with other pump or valve structures, or making precise numerical modifications to the bending radian of the stirring blade 46, or even making other modifications to the shape of the concentration tank 10, should fall into the protection scope of the present invention as equivalent or similar designs.
