(54) DEVICE FOR DRAINAGE OF PORK DRAIN

Lyg-1 and HapyjKHbiNJH with flanges and transverse internal partitions installed by the base and interconnected with each other and with a source of compressed air supply.

Fig, 1 shows the device type; in fig. 2, - the same, top view; FIG. 3 shows the sludge pressing chamber, general view; in FIG. A, a filter conveyor, general view; in FIG. 5 a section A-A in FIG. 3.

The device includes a lower filtration conveyor 1 installed on the frame; it is made in the form of sections 2 with side flanges and a rigid filtration wall 3 supported on the frame 4 through the axis 5 on the support rollers 6 moving along the guides 7; In this case, the base 9 of the chambers 8 forms a continuous endless tape. An annular closed duct is used to supply air, which is combined with hollow outer flanges 10 and internal partitions 1I communicating with each other. Air is supplied to the flanges 0 and the partition walls 1i from a compressed air source (not shown) through the opening 14 by connecting a flexible hose 12 having a power outer frame to prevent it from twisting through the sliding sleeve 13. At the locations of the cross partitions 11 the belt is supported on the axles i5s, each of which is provided with a pair of support rollers 16. The B chambers are moved through the tension pulleys 17, having grooves 18 for gripping the axles 15 with cantilever attachment to the frame, the original manure mass is In the tank 19 and enters the conveyor through the distributor 20, the filtrate is collected in the sump 21. For additional pressing of the obtained sludge and cleaning the filtration partition 3, the device is equipped with a squeeze roller 22, scraper 23 and a brush (rotating elastic ruff) 2,

The device works as follows,.

The original slurry is fed from the tank 19 to the distributor 20, from which a uniform thin layer flows onto the filtration partition 3, whereby the sections 2 of the filtration conveyor form a continuous, continuously moving flow, supported by the frame 4 of each section, supported by the rollers 6 through axis 5, moved along guides 7. As the initial manure mass is moved, a part of the filtrate penetrates through the filtration wall 3 and enters the pallet 21, the remaining manure is closed alternately by spinning chambers 8, each are formed by a base 9 and is bounded on the side of the outer hollow bkovyh flanges 10 and internal transverse partitions 11 hollow, pressing the density of the flanges 10 and transverse partition walls 11 provided in that they are provided with axes 15 supported on the rollers 16; To ensure the same speed of movement of the spin chamber and the filtration conveyor 1, the chambers with the common base interact with the tension pulleys 17 having grooves 18. the upper cavity of the chamber, squeezing the filtrate into the pan 21, air is supplied only when the spin chambers are horizontally positioned through spools (not shown), which are switched on at the moment of running onto the fixed guide and switched off at the moment tryva cameras from walls. The final dewatering of the uniformly distributed sediment through the thickness is realized by the squeezing roller 22, followed by cleaning the filter partition with a scraper 23 and a rotating elastic ruff 24.

The use of the proposed device will allow; increase the reliability of the installation; transfer to continuous operation; increase productivity; replace existing separation machines (vibratory, settling, centrifugal, etc.); allocate up to 80% of suspended matter to obtain a precipitate with a moisture content of 70%, which meets the zootechnical requirements for press filters,
