Description

The filter cloth cleaning device of sludge dewatering equipment

The utility model relates to a kind of filter cloth cleaning device of sludge dewatering equipment, particularly relates to the filter cloth cleaning device of the sludge dewatering equipment that a kind of filter cloth cleaning performance is good, water consumption is few.

As shown in Figure 1, the device of general sludge dewatering equipment has a conditioning groove 1, and this conditioning groove 1 adds mud after agglutinant stirs and be sent to centrifuge dehydration groove 2 that by the rotating centrifugal dehydration, partly moisture content gets rid of discharge in centrifuge dehydration groove 2; Mud through primary dewatering is then sent and is dropped on the working face of filter cloth 3 from centrifuge dehydration groove 2, and filter cloth 3 drives cyclic motion along clockwise direction by a plurality of rotating shafts 4 on this; Last filter cloth 3 surfaces have small net hole, make the part moisture content of mud utilize gravitational effects to drop onto in the tank 5 that is located at 3 up sections belows of filter cloth from small net hole, are to be the gravity dewatering process; Drop to relative and on the following filter cloth 6 with speed counter clockwise direction cyclic motion along advancing of last filter cloth 3 again through the mud of twice dehydration with last filter cloth 3, mud continues to advance, enter in the crack of 36 of upper and lower filter clothes, dewater and form sludge cake through a plurality of rotating shaft 4 press dewaterings, shearing, last mud 2 cakes that will be bonded on the upper and lower filter cloth 36 via the upper and

lower scraper

7,8 that is positioned at the exit strike off, and finish the operation of sludge dewatering.

Though this upper and

lower scraper

7,8 can strike off the mud that is bonded on the working face of upper and lower filter cloth 3,6, but because the filter cloth surface has the fine-structure mesh hole, the mud that more often is bonded on the filter cloth can't scraped clean, thereby is respectively equipped with filter cloth cleaning device 9 at the predetermined position of upper and lower filter cloth 3,6.As shown in Figure 2, this filter cloth cleaning device 9 utilizes a conduit 91 that water is imported in the water pipe 92, this water pipe 92 is provided with a plurality of fan nozzles 93, a plurality of fan nozzles 93 are towards the working face of filter cloth, down flow out or up spray to clean filter cloth by hydraulic pressure, still, still there is following shortcoming in this filter cloth cleaning device 9: one, the pressure with water itself down flows out or up ejection, pressure is often big inadequately, and because the angle of nozzle installing usually can't be cleaned upper and lower filter cloth very clean; Two, the entire working surface that must utilize a plurality of nozzles could clean filter cloth, and, needed 30～50 tons approximately in per by statistics eight hours from the effusive water of a plurality of nozzles, the cost cost is high.
