Description
Technical Field
The utility model relates to a device for improving the broken particle size of filter cakes of a plate-and-frame filter press, belonging to the field of sludge drying.
Background
The plate-and-frame filter press has the advantages of good sludge-water separation effect, high filter cake recovery rate, convenient operation, low investment and the like, and is widely applied to the field of sludge drying.
The high-dryness filter cake generated after the pressing of the plate-and-frame filter press needs to be crushed and can be used for incineration, sanitary landfill, land utilization and building material utilization. However, the particle size of the filter cake after being crushed by the existing matching crusher is large, which is not beneficial to burning or landfill, and the filter cake after being crushed is difficult to dissolve in water and can not be used by land any more. Therefore, the improvement of the broken particle size of the filter cake is the heavier weight of the crusher matched with the filter press.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a device for improving the crushed particle size of a filter cake of a plate-and-frame filter press, which aims to solve the problems in the background art.
The technical scheme of the utility model is as follows:
in order to achieve the purpose, the technical scheme adopted by the utility model is a device for improving the crushed particle size of a filter cake of a plate-and-frame filter press, and the device comprises a crushing roller, a disperser and a dredger, wherein the crushing roller is arranged in a feeding bin, the disperser penetrates through the front side surface and the rear side surface of the feeding bin, and the dredger is welded at the bottoms of the front side surface and the rear side surface of the feeding bin.
Preferably, the crushing roller comprises two crushing rollers which are arranged in a parallel and staggered manner, one crushing roller penetrates through the right side surface of the feeding bin and is connected with the motor, the other crushing roller penetrates through the left side surface of the feeding bin and is connected with the motor, and the crushing roller is made of Q235.
Preferably, the crushing roller consists of a shaft and a crushing fluted disc, the crushing teeth are uniformly distributed on the periphery of the crushing fluted disc, and the cross section of the crushing fluted disc is in a sawtooth shape.
Preferably, the deconcentrator sets up inside the feeding storehouse, the deconcentrator material adopts Q235, the deconcentrator through the welding mode with feeding storehouse leading flank and trailing flank are connected, the deconcentrator traverses the feeding storehouse, the deconcentrator is located in the middle of the feeding storehouse, the deconcentrator is formed by two steel sheet concatenation, is the chevron shape.
Preferably, the dredger is arranged inside the feeding bin, the dredger is arranged in two rows, the dredger is respectively connected with the bottom of the front side face and the bottom of the rear side face of the feeding bin in a welding mode, and the dredger is made of Q235.
Preferably, the front end of the dredger is a sawtooth-shaped steel plate which is alternately crossed with the crushing roller, and the rear end of the dredger is a strip-shaped steel plate which is connected with the bottom of the feeding bin.
The utility model has the beneficial effects that:
1. the device is provided with the disperser, so that the large mud cakes conveyed by the main belt conveyor can be broken and uniformly dispersed to two sides, because the mud contains a large amount of fibers, the mud cakes formed after being pressed by the plate-and-frame filter press are not easy to break, and if the mud cakes directly enter the crusher, the current of the crusher is instantaneously increased, so that the phenomenon of blocking is caused. The disperser effectively avoids the phenomenon.
2. The device is provided with the dredger, and sludge accumulated in the gap of the crushing roller can be cleaned in time. The sludge cake after being squeezed by the plate-and-frame filter press is high in hardness and easy to clamp between the two saw-tooth discs of the crushing roller, and cannot fall off by the gravity of the sludge, so that the sludge in the gaps between the two adjacent saw-tooth discs can be accumulated too much and too hard if not cleaned in time, and the crusher is blocked. The dredger effectively avoids the phenomenon.
3. The device adopts a novel crushing roller, the sawteeth on the crushing roller are small and dense, the two adjacent sawtoothed discs are also close, and the particle size of the crushed sludge cake can be controlled within a specific value even if the water content and the hardness of the sludge cake after being squeezed are low.

Detailed Description
The utility model is further illustrated by the following figures and examples.
In the description of the present invention, the terms "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in fig. 1-5, the device for improving the broken particle size of filter cake of plate-and-frame filter press comprises a breaking roller 1, a disperser 2 and a dredger 3, wherein the breaking roller 1 is installed inside a feeding bin 4, the disperser 2 penetrates through the front side surface and the back side surface of the feeding bin 4, and the dredger 3 is welded at the bottoms of the front side surface and the back side surface of the feeding bin 4.
