Abstract
The invention provides a squeezing filter plate and component for sludge high-pressure-drying dehydration equipment. The squeezing filter plate comprises a filter plate frame, filter cloth, a filter disc, and a center pipe for delivering sludge. The front surface of the filter plate frame is concave in one direction so as to form a filter-press chamber. The filter disc is arranged on the bottom of the filter-press chamber. The filter cloth is arranged on the filter disc. A telescoping cavity, which is telescoping and can be filled with fluids or gas, is arranged between the filter disc and the filter plate frame. A push plate device is also arranged between a rubber capsule and the filter disc. The filter-press component is composed of at least two squeezing filter plates, which are parallelly arranged. The concave in a filter plate frame and the back of a neighbored filter plate frame form a relatively enclosed sludge storage cavity with an electro-osmosis effect. By pressurizing the telescoping cavity through filling water into the cavity, the squeezing pressure on sludge is increased, at the same time, a push plate device is provided, thus the squeezing force becomes uniform, the whole process squeezing is realized, and the water content of sludge is further reduced.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
In the present invention, the noun of locality of use such as " upper and lower, left and right " typically refers to reference on shown in the drawings, under, left, right；In " inside and outside " refers to the profile relative to each parts itself, outward.
See Fig. 1 and Fig. 2: a kind of Filter pressing board for sludge high-drying dehydration equipment, this filter plate is multiple can form filter pressing assembly on sludge electroosmotic saturating high level cadre dehydration equipment, on filter pressing assembly, unidirectional recessed and another sheet frame the back side, adjacent sheet frame front constitutes an opposing seal, has effective storage mud cavity, can walk on pressure filter crossbeam.
As shown in Figure 1: this filter plate includes the compositions such as sheet frame 1, rubber bag tank 2, push pedal 3, filter disc 4, cathode screen 5, fairlead 6, center 7, filter cloth 8, insulation board 9, positive plate 10, sealing ring 11, cable 12 and fixing standard component.
Push pedal 3 is sleeved on the fairlead 6 being arranged on central canal, and push pedal 3 is placed between filter disc 4 and rubber bag tank 2, the version of rubber bag tank 2 be periphery be rubber, both sides are steel plate；Rubber bag tank 2 fixed form is to be connected with sheet frame 1, push pedal 3 by both sides steel plate by screw.The joint 9 of the intake-outlet of rubber bag tank 2 is located at sheet frame back, is connected fixing by hollow bolt 11, O 14 sealing and anti-leakage.
When sludge high-drying dehydration equipment prepares dehydration, at joint 109, water-filling is suppressed, and enters rubber bag tank 2 through hollow bolt 13.Now as it is shown in figure 1, rubber bag tank 2 extends to the left along fairlead 6, mud squeezes+electroosmotic dewatering to the left together with promoting push pedal 3, filter disc 4 and cathode screen 5.
