Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, in particular to a garbage leachate recycling device. Background Art

[0002] Since garbage can be divided into dry garbage and wet garbage, this point is not taken into consideration in the current garbage disposal, so garbage in different states will be concentrated together. Therefore, before the garbage is incinerated, in order to avoid the moisture in the garbage affecting its incineration effect, the moisture of the garbage needs to be drained in advance.

[0003] At present, the method of draining garbage is to directly place the garbage in the storage well for garbage, and then transport the leachate at the bottom of the storage well to the biogas pool for fermentation and utilization. However, in the treatment process, the leaching operation of the garbage is carried out by its gravity. However, after some garbage absorbs water, the moisture inside it is not easy to discharge under the action of gravity, which leads to the subsequent incineration of such garbage. The moisture inside will greatly affect its incineration effect, resulting in waste of resources. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a garbage leachate recycling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A garbage leachate recycling device comprises a biogas tank and a garbage storage well, wherein a leaching mechanism for leaching the garbage leachate is provided in the garbage storage well;

[0007] The leaching mechanism includes a partition fixedly connected to the lower part of the inner wall of the garbage storage well, the side wall of the partition is provided with a plurality of filter holes, the side wall of the garbage storage well is fixedly connected with a fixing frame, the upper end of the fixing frame is fixedly connected with two hydraulic cylinders, the movable end of the hydraulic cylinder is fixedly connected with a pressure plate, and the lower end of the pressure plate is fixedly connected with a plurality of push rods corresponding to the plurality of filter holes one by one.

[0008] Preferably, a liquid outlet pipe is fixedly connected to the lower end of the garbage storage well, a liquid inlet pipe and a gas outlet pipe are fixedly connected to the inner wall of the biogas tank, and two mounting plates are fixedly connected to the side walls of the liquid outlet pipe and the liquid inlet pipe, respectively. The two mounting plates are connected by multiple bolts.

[0009] Preferably, a discharge port is provided on the inner wall of the garbage storage well above the partition, and the side wall of the garbage storage well is rotatably connected to a cover plate via a rotating shaft, and the side wall of the cover plate is connected to the side wall of the garbage storage well via multiple bolts, and a rubber ring is glued to the cover plate near the side wall of the garbage storage well.

[0011] Preferably, the lower end of the garbage storage well is fixedly connected to a base via a plurality of support rods.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting up a leaching mechanism, the garbage in the garbage storage well can be pressed so that the water in the garbage can flow out through the filter holes in large quantities, ensuring the discharge of moisture in the garbage and avoiding the current garbage leaching operation that relies on gravity. However, after some garbage absorbs water, the moisture inside it is not easy to be discharged under the action of gravity, which leads to the subsequent incineration of such garbage.

DETAILED DESCRIPTION

[0019] 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.

[0020] Reference Figure 1-3 A garbage leachate recycling device includes a biogas tank 1 and a garbage storage well 2. The lower end of the garbage storage well 2 is fixedly connected to a base 15 through a plurality of support rods.

A pressure plate 11 is fixedly connected to the movable end of the hydraulic cylinder 10, and a plurality of push rods 12 corresponding to the plurality of filter holes 8 are fixedly connected to the lower end of the pressure plate 11.

[0023] Furthermore, when the garbage is leaching, the two hydraulic cylinders 10 can be adjusted to extend, and then the pressure plate 11 can be moved down to press the garbage in the garbage storage well 2, so that the water in the garbage can flow out through the filter holes 8 in large quantities, ensuring the discharge of the water in the garbage, and avoiding the current garbage leaching operation is carried out by gravity, but some garbage after absorbing water, its internal water is not easy to discharge under the action of gravity, so that when the garbage is subsequently incinerated, the internal water will greatly affect its incineration effect, resulting in a waste of resources;

[0024] And after the garbage in the garbage storage well 2 is cleaned up later, the pressure plate 11 can drive the multiple top rods 12 to move downward, and then the multiple top rods 12 can be inserted into the multiple filter holes 8 to clean the garbage in the filter holes 8, so as to avoid the accumulation of garbage in the filter holes 8 and affect the subsequent infiltration of water in the garbage.

[0028] The discharged water will then enter the biogas tank 1 through the liquid outlet pipe 3 and the liquid inlet pipe 4 for fermentation treatment, thereby realizing the utilization of the garbage leachate;

[0029] After the water in the garbage is drained, the two hydraulic cylinders 10 are adjusted to contract and drive the pressure plate 11 back to the original position. Then the staff rotates the bolts to rotate the cover plate 14 downward to open the discharge port 13, so that the garbage in the garbage storage well 2 can be taken out through the discharge port 13 for subsequent incineration treatment.

[0030] After the garbage is processed, the staff can clean the garbage storage well 2. The specific operations are as follows:
