[0023] In this embodiment, the snail stacking machine body 1, the mixing box 2 and the cleaning box 3 constitute the main structure of the snail stacking machine involved in this application for facilitating the collection of sludge, wherein the structure of the snail stacking machine body 1 is consistent with the snail stacking machine involved in the prior art.

[0024] Specifically, a sludge inlet pipe is connected to the bottom of the sludge inlet box 3 , and the sludge inlet box 3 is communicated with the mixing box 2 .

[0025] like Figure 1 and Figure 4 As shown, the screw stacking machine body 1 includes a hollow chassis on the lower side, and the filter box 15 is obliquely installed on the upper side of the chassis, and the partition 14 is installed inside the chassis, and the upper end of the partition 14 is connected to the bottom of the filter box 15, the outer side of the filter box 15 is set as a cylindrical screen structure, and the interior of the filter box 15 is provided with a rotatably connected drive shaft, and the outer wall of the drive shaft is welded with a screw stacking sheet 16, and the left end of the drive shaft is connected with a reducer 17, a mud outlet is opened at the left end of the filter box 15, and the collecting box 11 is installed on the lower side of the mud outlet, and a mounting plate 18 is fixed on the driving shaft on the upper side of the collecting box 11, and a back pressure plate 19 is connected to the mounting plate 18 toward the mud outlet side, and a cutting blade 110 is welded to the back pressure plate 19 toward the mud outlet side.

[0026] As a preferred embodiment, by setting the partition 14, the sewage with less mud content can be discharged after the sludge with high water content that just enters is filtered. At the same time, under the rotation and extrusion of the spiral stack 16, the mud content of the sewage at the filtration point on the other side of the partition 14 is greatly increased, so it can be drawn back to the mud inlet box 23 through the circulation hole 12 for further filtration.

[0027] As a preferred embodiment, the cutting blade 110 is configured as an L-shaped structure, so that during the synchronous rotation of the back pressure plate 19, the cutting blade 110 can break up the mud cake discharged in block form for easy collection.

[0030] like Figure 1 As shown, a rotatably connected screw rod 31 is provided inside the cleaning box 3, and a screw sleeve 32 is screwed on the outer side of the screw rod 31, and a cleaning ring 33 is connected to the lower end of the screw sleeve 32, and a guide rod 35 is slidably connected to the top of the cleaning ring 33, and the guide rod 35 is arranged parallel to the screw rod 31, and cleaning blocks 34 arranged in a ring-shaped matrix are provided on the inner ring wall of the cleaning ring 33.

Compared with the direct high-pressure flushing in the right technology, it is wrapped by the cleaning ring 33 and started and used simultaneously with the nozzle 38, so that the cleaning is more thorough and comprehensive. In addition, during filtering, the nozzle 38 can spray clean water to flush the screen holes of the filter cartridge to prevent clogging.

[0032] When in use, the main body of the spiral stacking machine is started, and the sludge is introduced into the mixing box through the mud inlet box, and then the coagulant is added into the mixing box through the coagulant input pipe. Then, under the drive of the stirring motor and the stirring shaft, the sludge and the coagulant are mixed to facilitate the agglomeration of the sludge, and then the sludge enters the filter box through the bent pipe. During the rotation, extrusion and transportation of the driving shaft and the spiral stacking pieces, a part of the sewage is filtered through the bottom screen of the filter box, and then discharged through the water outlet. When it is transported to the high end of the filter box, the sludge content of the sludge increases, and the sewage filtered out of the screen in time contains more sludge. At this time, the sludge enters the internal space of the chassis, and is pumped back to the mud inlet box by the rotating pump through the circulation hole and the mud pumping pipe for filtering again. The sludge reaching the top of the filter box becomes a block structure at this time. When it is discharged from the mud outlet, the rotating back pressure plate is used to limit the block during the discharge process, and the cutting disc is used to cut small-sized pieces, which is convenient for collection in the collection box.

[0033] The snail stacking machine for collecting sludge of the utility model can effectively solve the problem that the snail stacking machine for collecting sludge is not convenient for cleaning the internal filtering structure and the mud content of the discharged filtrate is still relatively large. It is convenient to clean the internal filtering structure of the snail stacking machine on the basis of the existing technology of the snail stacking machine for collecting sludge, and at the same time achieves the secondary circulation filtering effect, thereby reducing the mud content of the discharged filtrate.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
