DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figures 1 to 5 A pre-treatment device for landfill includes a shell 1, an inlet 2 and a deflection shielding plate 3. The garbage to be compressed is input into the internal cavity through the inlet 2. When the compression link is executed, one end of the garbage is in contact with the deflection shielding plate 3 to realize the bearing activity of the compressed garbage. After the compression is completed, the deflection shielding plate 3 is opened to realize the unloading activity.

[0028] A filter plate 4 is mounted on the bottom of the housing 1, and long strip-shaped liquid drop holes are evenly and equidistantly provided on the filter plate 4;

[0029] During the compression stage, the solid will be separated from the liquid. At this time, the liquid can fall through the long strip-shaped liquid drop holes on the filter plate 4, thereby reducing the weight of the compressed garbage and facilitating subsequent transportation and landfill activities.

[0030] A push plate 9 is slidably installed inside the shell 1. By moving the push plate 9 inside the shell 1, the garbage can be driven to gather toward one end of the shell 1, thereby achieving compression activity.

[0031] A sliding plate 11 is slidably mounted on the push plate 9 , a strong spring 20 is arranged between the push plate 9 and the sliding plate 11 , and two ends of the strong spring 20 are respectively fixedly mounted on the groove inside the push plate 9 and the protruding part of the sliding plate 11 .

[0032] A connecting rod 13 is fixedly mounted on the sliding plate 11, a mounting plate 14 is fixedly mounted on the connecting rod 13, and cleaning blocks 15 are fixedly mounted on the mounting plate 14 at equal distances and uniformly;

[0033] The cleaning block 15 is matched with the long strip-shaped liquid drop hole on the filter plate 4, and can clean the mud, debris and the like that clog the liquid drop hole.

[0034] The strong spring 20 is used to provide a downward force for the cleaning block 15 so that the cleaning block 15 can smoothly pass through the obstruction on the liquid drop hole even if it encounters an obstacle.

[0035] The height change of the sliding plate 11 can change the height of the cleaning block 15, so that the cleaning block 15 can extend into the long strip-shaped liquid drop hole to clean the blockage, so that the liquid can fall effectively.

[0036] Height changing components 8 capable of changing the height of the sliding plate 11 are disposed on both sides of the housing 1 .

[0037] The height changing assembly 8 can adjust the height of the cleaning block 15 synchronously according to the position of the long strip-shaped liquid drop hole.

[0038] Pulleys 16 are fixedly mounted on both sides of the sliding plate 11 .

[0039] The height changing assembly 8 includes a plane block 17 and an adjusting block 18, and the front view of the adjusting block 18 is an isosceles triangle.

[0040] The plane block 17 is connected to the adjusting block 18 , and both the plane block 17 and the adjusting block 18 are provided with a slide groove 19 for the pulley 16 to slide.

[0041] When the pulley 16 moves inside the slide groove 19 on the plane block 17, the cleaning block 15 is in a normal lower state. At this time, the liquid drop holes on the filter plate 4 are cleaned. When the pulley 16 slides on the slide groove 19 on the adjustment block 18, the height of the cleaning block 15 first rises. At this time, the cleaning block 15 does not contact the liquid drop holes on the filter plate 4 and can move normally above the filter plate 4. Afterwards, the height of the cleaning block 15 decreases. At this time, the cleaning block 15 contacts the liquid drop holes on the filter plate 4. The setting of the height change component 8 allows the cleaning block 15 to pass over the area on the filter plate 4 where there are no liquid drop holes.

[0042] A liquid storage box 5 is fixedly installed at the bottom of the shell 1 , and a liquid discharge pipe 6 is embedded and installed on the liquid storage box 5 . The liquid storage box 5 is located directly below the filter plate 4 and is connected to the space below the filter plate 4 .

[0043] The bottom plane inside the shell 1 is a structure with high sides and low middle, which can facilitate the outflow of liquid.

[0044] The liquid in the garbage falls into the liquid storage box 5 through the liquid drop holes on the filter plate 4, and then the liquid is discharged under the action of the liquid discharge pipe 6. The inside of the liquid storage box 5 can be opened, so as to facilitate cleaning activities.

[0045] Two threaded rods 7 are rotatably mounted inside the housing 1 . Both threaded rods 7 are connected to nut pairs 10 through threads. The nut pairs 10 are fixedly mounted on the push plate 9 .

[0046] When the two threaded rods 7 rotate synchronously, the nut pairs 10 on the two threaded rods 7 move synchronously, so that the push plate 9 can drive the garbage to move to one side, and at this time, the garbage compression activity can be performed.

[0047] Two drive motors 12 are arranged on the housing 1. The shaft output ends of the two drive motors 12 are fixedly connected to the center of the corresponding threaded rod 7. The two drive motors 12 are started and stopped synchronously. The start of the drive motors 12 can make the two threaded rods 7 rotate synchronously.

[0048] The working process of the utility model is as follows: the garbage to be compressed is input into the internal cavity through the feed port 2. When it is filled to a predetermined value, the two driving motors 12 are started, and the two threaded rods 7 rotate synchronously, and then the nut pairs 10 on the two threaded rods 7 move synchronously, so that the push plate 9 can drive the garbage to move to one side. At this time, the garbage compression activity can be carried out.

[0049] When the push plate 9 moves forward, the pulleys 16 on both sides of the sliding plate 11 slide on the sliding grooves 19 .

[0050] When the pulley 16 moves inside the slide groove 19 on the plane block 17, the cleaning block 15 is in a normal lower state, at which time, the liquid drop holes on the filter plate 4 are cleaned.

[0051] When the pulley 16 slides in the slide groove 19 on the adjusting block 18 , the height of the cleaning block 15 rises first. At this time, the cleaning block 15 is not in contact with the liquid drop hole on the filter plate 4 and can move normally above the filter plate 4 .

[0052] Afterwards, the height of the cleaning block 15 is lowered, and at this time, the cleaning block 15 contacts the liquid drop holes on the filter plate 4 again. The setting of the height change component 8 enables the cleaning block 15 to pass over the portion of the filter plate 4 without liquid drop holes.

[0053] During the compression stage, the solid will be separated from the liquid, and the liquid in the garbage will fall into the liquid storage box 5 through the liquid drop holes on the filter plate 4. The liquid will then be discharged through the drain pipe 6. The inside of the liquid storage box 5 can be opened to facilitate cleaning activities.

[0054] When the compression is completed, the deflection shielding plate 3 is opened, and the push plate 9 continues to push the garbage, and the material unloading activity can be carried out.

[0055] 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.
