    J The invention relates to a device for treating a pulp-like suspension of solids, in particular for the preliminary dewatering of clarifying sludge, paper pulp, etc., COMPOSITION 1; from a preprocessing station with an outlet connected to an inlet of a squeezing device. A press with a pretreatment station is known, consisting of two press augers located in one housing. With this device, a pulp suspension of solids is pressed and fed to a screw press for subsequent pressing of C13. However, this device is uneconomical when working with a suspension with a high water content, for example, 95%. The closest to the technical issue of the technical essence and the achieved result is a device containing a pretreatment station with an inlet opening and an outlet opening connected to the inlet opening of the squeezing means 2. A disadvantage of the known device is low productivity. The purpose of the invention is to increase productivity while reducing energy costs. The goal is achieved by the fact that in the device containing. The pretreatment station with the inlet and the outlet connected to the inlet of the squeezing means, the pretreatment station is made in the form of rotary receiving plates - perforated oeaeDBvaDOB made of tin, installed in the holes; it is equipped with a fixed squeak with eccentrically located openings corresponding to the outer surface The first perpendicular reservoir and the inlet opening of the squeeze tube are in the form of a cylinder, cone, oval or rectangle. It is advisable to provide a perforated tank on the inner surface with a mesh or filter cloth .. 6 .2 - It is preferable to provide devices with a funnel-shaped catch tank or an annular channel located under the fixed disc and connected to its outlet. . It is advisable to provide the device with a seal placed between the fixed disk and the perforated tank in the opening of the swivel receiving plate, and made in the form of a receiving ring with a collar facing the stationary disk and the elastic ring going out. the lower edge of the collar and located around it. Preferably, the seal is provided with an elastic sliding ring located between the bottom surface of the swivel plate and the elastic ring located on the fixed disk. In FIG. 1 is a view of the SI1 “common device, general VID5 in FIG. 2 a filling nozzle with a filtering sleeve in the form of a stocking attached thereto; a general view5 of FIG. 3 fixed disk with eccentrically located holes, type of xy; in fig. 4 shows a swiveling receiving plate, top view; in FIG. 5, a cone-shaped container of perforated tin, general view; in fig. 6 — rectangular container of perforated tin; in fig. 7. The pressing device with a receiving swivel plate, made in the form of a cylindrical container, cut in FIG. 8 - fixed disk, top view; in fig. 9 base plate of the swivel receiving plate, top view; in fig. 10 - sealing the container from perforated tin; in fig. 11 another embodiment of the seal 5 in FIG. 12 — node I in FIG. 7. The device consists of a pretreatment station 1 and a wring-out screw press 2. The device has a filling nozzle 3 for filling the containers 4-6 from perforated tin. The containers are installed with the possibility of EO rotation. And by means of the receiving rotary plate 7 in the direction of the arrow 8. The tanks have openings 9 through which they are connected to a stationary disk 10. The pressing screw-2 is equipped with a receiving chamber 11. The device is equipped with 311 catching means 12. Through the opening 13 in the receiving swivel plate and the hole 14 in the fixed disk 10, the liquid enters the closed discharge channel 15. The screw 16 of the screw press 2 rotates in the direction of arrow 17 and transports a mixture of liquid and solids in the direction of and arrows 18. The inlet part 19 of the screw press has holes 20 through which liquid is pressed in it. There are radial drills 21 in the auger turn, which are connected to axial drilling 22 along the auger, due to which the dry content is achievable depending on the type of material. substance up to 90%. The device is equipped with a punch 23. It can also be made in the form of a brush and can be operated mainly by means of pneumatics. Using a drive gear 24, which drives a rotation from a drive assembly (not shown) and engages with an internal gear 25 of the swivel receiving plate 7, the corresponding perforated tin receptacle on the swiveling receiving plate 7 alternately passes through the opening 9 of the fixed disk 10 therefore, it can be emptied. In chamber 26, ten receptacles 27-36 of perforated tin are placed. The perforated sheet container 27 is in the emptying position through the opening 37 of the base plate 38. With the downward movement of the punch 39, the process of pushing out and simultaneously cleaning the walls of the container from perforated sheet can be carried out. The released fluid exits through the central tapping hole 40 or through the longitudinal hole 41 in the base plate 38 and through the central hole 42 or the longitudinal hole 43 of the fixed disk 44. Then the liquid is collected in the collecting funnel 45 located under the fixed disk 44, and discharged. If the contents of the perforated sheet container 27 are emptied into the receiving chamber 46 of the screw press, the pre-dried mixture is in the screw press 2. Through the opening 20, LIQUID released in the screw press is withdrawn. In order to avoid accumulations of the pressed mixture in the support of the screw press, the latter is made with a reverse thread 47, which creates a counteraction, and therefore excludes contamination on the auger supports. The cylindrical container is alternately driven in the direction of the arrow 49 (FIG. 9) by means of a drive device with gear wheels 48 (FIG. 9), respectively, through the holes 37 of one of the containers from perforated sheet 27-36 so that the contents of the container from perforated sheet are previously drained to the receiving chamber 46 The containers of perforated sheet (Fig. 7) are made removable, they can be freely removed to be cleaned or repaired without stopping the work of the pretreatment station. Only further connection of the swiveling receiving plate to the removable container is required. The filling nozzle 3 is equipped with a filtering sleeve 50 in the form of a stocking. FIG. 5 shows a cone-shaped container 51 of perforated tin, which is made with an OKOTit 5 taper angle and expands downwards. Such a design is advantageous because the solid particles in the upper part of the container, when the level of the contents of the container decreases, under the action of gravity, are separated from the wall of the container towards the bottom, due to which this container spontaneously clears. FIG. 6 shows a rectangular container 52 of perforated sheet metal with an average line 53. Since the fixed disk 44 and the base plate 38 are made of metal with high sliding properties, energy costs are reduced by alternately moving containers or turning the receiving plate 7 from the drive. A seal 54 is fixed on the lower edge of the perforated sheet container 32 (FIG. 10), which slides over the fixed disk 44 during the alternate rotation of the base plate 38. The receiving ring 56 is shown in the passage 55 (FIG. 11) of the base plate 38, welded to the base plate 38 and having a shoulder 57. Around
    the protruding shoulder is elastic ynnotKeHne 56 from a Material with good sliding properties. The elastic seal 58 protrudes through the lower lip 59 of the receiving ring 56, thereby eliminating friction of the receiving ring 56. b fixed disc 44.
    . The preferred form of embodiment shown in FIG. 12 also has a receiving ring 56, around which lower edge 59 there is an elastic sliding ring 60, which presses the plastic seal 61 relative to the fixed disk 44,
    The device works as follows.
    Subject to a dehydrated mixture, for example, a fiber-containing cadium sludge clarified with a dry substance content of about 5%, through a filling tube 3 fills a container 4 of perforated sheet metal. The liquid flows through the perforated walls of the container so that in a very short time the forage cover is reduced. With the help of the swivel receiving plate 7, the three containers 4-6 from perforated tin are rotated in the direction of the arrow 8 so T6. the container 6 is installed under the sealing pipe 3, and the container 5 is installed above the hole 9 of the non-mounted disk 10. The liquid escaping from the envelope of the container from the Perfop Orbit of its tin is captured by means of the catching means 12 which is rigidly connected to the fixed disc 10, and is directed through the opening 13 in the receiving swivel plate 7 and open 14 in the disk 10 in the closed bypass passage 15 finds schiIs above the disk 10 and is rigidly connected with it, № | ek 16
    The press 2 rotates in the direction of the arrow .17 and, therefore, captures the mixture of liquid and solids and transports it in the arrow 18 direction. With the help of the screw auger 16, the mixture is further compressed so that a further spin effect is achieved. Through the openings 20, liquid released in the inlet of the screw press is withdrawn. Further drying in the front of the screw press 2 occurs through radial drills 21 in the auger turn, which are connected to axial drilling -22 along the screw, thereby becoming achievable, depending on the type of material, to bring the substance to the bitch to 90%, using a punch 39, respectively under it a container made of perforated tin is emptied, cleared, or the contents of the container is precompacted. With the help of a drive gear 24, engaged with an internal gear 25, the receiving gear hydrochloric plates 7, sootvetstvunzscha capacity of perforated sheet metal or receiving the rotary plate 7 alternately pass through the aperture of the stationary disc 9 and emptied.
    If, for pre-drying, a larger number of tanks from perforating (tinned and tin) are provided, moving around the circumference of the swivel plate one after the other, passing to the eccentric flaps in the fixed disk, empty and immediately filled with the initial mixture, then continuous pre-dewatering is obtained with very high throughput at low energy costs.
    The proposed device is also reliable because of its low sensitivity to interference and provides continuous high-quality preliminary dewatering of, for example, sludge from 4 to 10% of the dry substance content.
