    Continuous washing device for filter for liquid filtration {LIQUID THE USE OF FILTERATION FILTER CONTINUOUS WASHIN SYSTEM}
    The present invention relates to a continuous cleaning device for a liquid filtration filter having a self-cleaning device and automatically cleaning the filter while continuously filtering the liquid.
    In general, when the filter network is polluted by dirt in the process of passing the liquid through the filter network, the filter network must be replaced or periodically cleaned (or backwashed). It is necessary to stockpile the stock, and when it is replaced, the labor cost and loss of filtration process will be accompanied. Therefore, it is desirable to try to clean the filter network while continuing the filtration work if possible. Therefore, in order to clean the filter network while performing the filtration continuously, there is an economic overload according to the separate cleaning by installing a pre-filter separately.
    There is an automatic backwash filter that has been developed recently to solve this problem, but it enables automatic backwashing by rotating or moving the filter net or backwash outlet using the pressure of the motor or air. The principle of the automatic backwash filter is not only to increase the power ratio due to driving, leakage of the motor shaft connection part, and to reduce the raw water (or liquid) utilization rate due to the large amount of backwash water discharge and to increase the failure rate. The filter network is not completely cleaned and the filter is filtered by the instantaneous pressure change because the ice is discharged to the outside after adjusting the waste outlet on the filtering source side of the network (using the pressure difference between the filter water and the outside). There was a defect that damaged the network.
    The present invention has been invented to solve the above-described drawbacks. The present invention is not only to completely clean the filter network in the process of cleaning the filter network during filtration, but also to prevent damage to the filter network, Continuous backwashing is possible without the use of auxiliary energy sources.

    As shown in FIG. 1, the rotary shaft 3, which serves as a backwash water supply pipe 3 'installed at the center of the filter body 19, functions to continuously filter and backwash liquid in the filter body 19. Rotating vanes 2 are fitted in the upper part, and a plurality of backwash water distribution pipes 4 are installed at the center of the rotating shaft 3, but a plurality of backwash water discharge sleds is connected to the backwash water discharge pipe 5 connected to the front end thereof. 6) is formed, and the filter filter cover plate 17, the filter body cover plate 21 and the filter filter network lower support plate 18 through the bearing (14) and seals (15) and (16) above and below the rotating shaft (3). Is installed, but the upper and lower gaskets (12, 13) are installed between the upper and lower gaskets, and the cylindrical filter filter (11) is installed. The back washing water supply pipe (7) and the filtered water outlet (9) are installed and the bottom of the filter body (19) Is a top, the structure is filtered raw water inlet (1) and the wash station inlet port 8 formed in the peolteo waste outlet 10 of the funnel-shaped formed body (1).
    The content shown in FIG. 2 is a cross-sectional view of the rotor blade (2) to explain the principle of the rotation of the rotor blade (2) and FIG. 3 is a rotary shaft (3), backwash water distribution pipe (4), backwash water discharge pipe ( 5 is a cross-sectional view illustrating the principle of backwashing and FIG. 4 is a schematic diagram of a system of a liquid filtration filter, and a filter body 19, a backwash pump 26, a filter residue discharge valve 23, a filtrate discharge valve, and backwashing. It is a schematic explanatory drawing of components, such as a pump supply valve 25, and a system. 5 is a schematic diagram of a system in the case of backwashing with air as a separate embodiment of the present invention, adding the air supply pipe 27 'and the automatic air 928 via the blower 27, and backwash pump supply pipe 7, It is a schematic explanatory drawing of the system except the backwash pump supply valve 25 and the backwash pump 26.
    The present invention configured as described above is a continuous washing device of the filter for liquid filtration, when performing this, the filtered raw water introduced through the filtered water inlet (1) flows in the tangential direction of the filter body (19) and rotates with the force of the liquid flow. The blade 2 flows into the vacancy of the filter body 19 outside of the filtration filter net 11 through a passage formed in the bar portion of the cover plate 17 of the filtration filter net 11 while rotating the wing 2. At this time, the filtration raw water is introduced into the interior from the outside of the filtration filter network 11, the filtration operation is made as usual, and then discharged through the filtration water outlet 9 and the filtration water discharge valve 24 to obtain a clean liquid.
    At this time, the filtered water discharge valve 24 serves to control the amount of filtered water and to maintain the pressure in the filter to ensure the backwashing water in the filter body (19). Part of the filtered filtrate is introduced into the backwash pump 26 through the backwash pump supply pipe 7 and the backwash pump supply valve 25, and then pressurized into the backwash water inflow tube 8. The amount of backwash water is controlled by the adjustment of the backwash pump supply valve 25 according to the amount of debris contained in the filtered raw water.
    In addition, in order to reduce the waste of power by the continuous operation of the backwash pump 26, by installing a differential pressure switch at the inlet and the filtered water outlet, which is the filtration source, it is possible to control the operation of the backwash pump 26 according to the increase of the differential pressure. The backwash water introduced into the backwash water inlet 8 is distributed to the respective backwash water distribution pipes 4 through the rotary shaft 3 and the backwash water supply pipe 3 ', and then flows into the backwash water discharge pipe 5 and backwash water. At the end of the discharge pipe (5) is discharged at a high flow rate through the backwash water discharge slits (6) which are drilled perpendicularly to the filter network (11).
    In order to prevent power loss due to excessive liquid flow and maintain balance during rotation of the rotating shaft and the backwash water supply pipe (3 '), the backwash distribution pipe (4) is divided into four directions from the top to the bottom and then in four directions (+ The backwashing water discharged at a high flow rate is discharged in the opposite direction to the filtration source (from inside to outside of the filtration filter network 11) and filtered through the outside filter network because the internal backwashing distribution pipe is differentially configured. Clean out the debris evenly. And as shown in Figure 5 separate embodiment the backwash pump supply pipe (7) instead of the backwash pump supply valve (25) and backwash pump (26) through the blower 27 and the air supply pipe (27 ') the backwash water inlet ( It is also possible to clean the residue of the filter network 11 even if supplied to 8). At this time, by installing the automatic air cement 28 in the filter body cover plate 21 to discharge the air accumulated (compressed) in the filter body.
    Continuous rotation of the rotating shaft 3 and the backwash water supply pipe 3 'by the rotary blade 2 causes the backwash water distribution pipe 4 and the backwash water discharge pipe 5 to rotate together so that the backwash water is filtered through a filter network ( 11) It will play an important role in allowing you to backwash the whole part evenly.
    In addition, the filtered raw water flowing in the tangential direction to the filter body 19 is settled downward while rotating from the outside of the inside of the filter body 19 by centrifugal force by the swirl flow generated when flowing in the tangential direction. This increases the removal efficiency of the debris. And the debris separated from the surface of the filter filter net 11 sinks downward by gravity and collects downward through the hole in the bar portion of the lower support plate 18 of the filter filter net.
    Thus, the waste collected in the lower portion can be removed by discharging to the outside through the filter waste discharge pipe 10 and the filter waste discharge valve (23). In order to increase the utilization rate of the filtered raw water, the filter residue discharge valve 23 may be formed to adjust the concentration of the discharged waste, and in the case of recovering the raw material (the residue) in the liquid, the concentration of the raw material may be adjusted.
    As described above, the present invention not only can reduce the amount of backwash discharged water compared to the conventional liquid filter, but also backwashing is possible only when the backwash water used for backwashing is completely discharged to the outside, but the present invention circulates a part of the filtered filtrate. After backwashing, the backwash water used for backwashing is present in the filter as it is, and the backwash water is discharged only by the control of the filter residue discharge valve. It is possible to backwash and double the filtration efficiency, which can make a great commercial contribution.
