Description

Technical Field

[0001] The utility model belongs to the technical field of landfill leachate treatment, and particularly relates to a landfill leachate pretreatment device. Background Art

[0002] Landfill leachate refers to the water contained in the garbage itself in the landfill, rain and snow water entering the landfill and other water. After deducting the saturated water holding capacity of the garbage and the covering soil layer, and passing through the garbage layer and the covering soil layer, a high-concentration organic wastewater is formed. The leachate in the garbage will seriously affect the incineration treatment of the garbage. Therefore, it is necessary to pre-treat the water in the garbage in advance. After the common landfill leachate treatment device completes the treatment of the water in the garbage, it is not convenient to take out the treated garbage from the device, and it is not convenient to carry out subsequent transportation treatment after the garbage is taken out. For this reason, this application proposes a landfill leachate pretreatment device. Content of the Utility Model

A semi-circular opening is provided at the upper position of the side wall of the barrel body. A liftable filter plate is arranged at the bottom of the inner cavity of the barrel body. A number of filter holes are evenly opened on the surface of the filter plate. A first hydraulic rod is fixedly installed at the middle position of the top of the barrel body. The telescopic end of the first hydraulic rod extends into the barrel body, and an extrusion plate is fixedly installed at the telescopic end of the first hydraulic rod. The extrusion plate is located above the opening. A plate groove is opened on the inner wall of the barrel body on the side far away from the opening. A push plate is arranged in the plate groove. A third hydraulic rod is fixedly installed on the outer wall of the barrel body on the side far away from the opening. The telescopic end of the third hydraulic rod penetrates through the side wall of the barrel body and extends into the plate groove and is fixedly connected with the push plate.

[0004] Further, the position of the plate groove is the same as the height of the opening, and the plate groove and the opening are distributed left and right. The push plate is set to be arc-shaped, and when the push plate is located in the plate groove, the inner wall of the push plate is flush with the inner wall of the barrel body.

[0005] Further, the width of the push plate is smaller than the width of the opening, and the top and bottom of the push plate are respectively flush with the top and bottom of the opening.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0018] By Figures 1-4Provided that, the utility model includes a barrel body 1. A semi-circular opening 2 is provided at the upper position of the side wall of the barrel body 1. A liftable filter plate 3 is arranged at the bottom of the inner cavity of the barrel body 1. A plurality of filter holes 4 are evenly arranged on the surface of the filter plate 3. A first hydraulic rod 5 is fixedly installed at the middle position of the top of the barrel body 1. The telescopic end of the first hydraulic rod 5 extends into the barrel body 1, and an extrusion plate 6 is fixedly installed at the telescopic end of the first hydraulic rod 5. The extrusion plate 6 is located above the opening 2. A plate groove 11 is provided on the inner wall of the barrel body 1 on the side far away from the opening 2. A push plate 12 is arranged in the plate groove 11. A third hydraulic rod 13 is fixedly installed on the outer wall of the barrel body 1 on the side far away from the opening 2. The telescopic end of the third hydraulic rod 13 penetrates through the side wall of the barrel body 1 and extends into the plate groove 11 and is fixedly connected with the push plate 12.

[0019] Meanwhile, the position of the plate groove 11 is the same as the height of the opening 2, and the plate groove 11 and the opening 2 are distributed left and right. The push plate 12 is arranged in an arc shape. When the push plate 12 is located in the plate groove 11, the inner wall of the push plate 12 is flush with the inner wall of the barrel body 1, so as to prevent the push plate 12 from affecting the up and down movement of the extrusion plate 6 in the barrel body 1.

[0020] In addition, the width of the push plate 12 is smaller than the width of the opening 2. The top and bottom of the push plate 12 are respectively flush with the top and bottom of the opening 2. After extrusion is completed, control the second hydraulic rod 7 to push the filter plate 3 up until its top is flush with the bottom of the opening 2, and then control the third hydraulic rod 13 to drive the push plate 12 out of the plate groove 11. Under the pushing action of the push plate 12, the garbage squeezed on the top of the filter plate 3 can be smoothly pushed out from the opening 2.

[0021] Moreover, the bottom of the inner cavity of the barrel body 1 is arranged as an inclined plane, and a sewage discharge port 9 is provided at the end with a lower horizontal height at the bottom of the inner cavity of the barrel body 1. In this way, under the extrusion action of the extrusion plate 6, the water in the garbage will flow down through the plurality of filter holes 4 on the filter plate 3 and finally be discharged from the sewage discharge port 9 along the inclined plane at the bottom of the barrel body 1.

[0022] Furthermore, four fixing blocks 8 arranged in a circular array are evenly and fixedly installed at the lower position of the inner wall of the barrel body 1. The bottom of the filter plate 3 abuts against the tops of the four fixing blocks 8. A second hydraulic rod 7 is fixedly installed at the middle position of the bottom of the barrel body 1. The telescopic end of the second hydraulic rod 7 extends into the barrel body 1 and is fixedly connected to the center of the bottom of the filter plate 3. By controlling the second hydraulic rod 7, the filter plate 3 can be driven to move up and down in the barrel body 1. The four fixing blocks 8 can limit the downward movement degree of the filter plate 3, and the four fixing blocks 8 can support the filter plate 3 to prevent the filter plate 3 from moving downward when the extrusion plate 6 squeezes the garbage on the filter plate 3.

[0023] In addition, four support legs 10 are evenly and fixedly installed at the bottom of the barrel body 1. The four support legs 10 can stably support the barrel body 1 and reserve space for the installation of the second hydraulic rod 7 at the bottom of the barrel body 1.

[0024] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0025] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
