Description

Technical Field

[0001] The utility model relates to the field of garbage leachate treatment devices, in particular to a filter for pre-removing slag from garbage leachate. Background Art

[0002] Leachate refers to a high-concentration organic wastewater formed by the moisture contained in the garbage itself in the landfill, the rain and snow water entering the landfill, and other moisture, minus the saturated water holding capacity of the garbage and overburden layer, and passing through the garbage layer and overburden layer. In the process of treating leachate, the impurities in the leachate must first be pre-treated and filtered, so a filter for pre-removal of leachate is needed.

[0003] For example, the Chinese utility model (publication number CN209548846U) discloses a filter for pre-slag removal of landfill leachate, including a filter box, a reflux storage device box, a mounting plate, a 25FP-10 industrial pressure pump and a discharge pipe, etc. According to the technical solution, after the impurities are separated by the first filter plate, etc., a small amount of landfill leachate enters the interior of the reflux storage device box, thereby preventing the filtered liquid inside the reflux storage device box from being discharged along with the pre-slag removal and causing pollution to the land.

[0004] However, the above-mentioned redemption scheme still has the following technical problems when it is actually used: the leachate itself has a certain odor, and the above-mentioned technical scheme does not set up a corresponding purification device during the treatment process, which causes the odor to spread randomly during the treatment process, affecting the working environment and causing damage to the health of the staff. It is less practical and inconvenient to use. Utility Model Content

The adsorption plate can be made of a hygroscopic material, etc. The connecting block 27 is connected with a sealing pad 29, and the width of the sealing pad 29 increases from bottom to top. After the connecting block 27 is inserted into the connecting through hole 28, the sealing pad 29 contacts the side wall of the connecting through hole 28.

[0024] The storage box 3 is slidably connected to the filter frame 22, the filter box 5 is connected to the dosing pipe 6, and the dosing pipe 6 is connected to the sealing cover 7; the balance pipe 11 is connected to the one-way valve 10, and the one-way valve 10 can only pass the medium from top to bottom, that is, the air can only enter the filter box 5 from the outside of the filter box 5 through the balance pipe 11; the bottom of the storage box 3 is connected to the return pipe 4, the return pipe 4 is connected to the filter box 5, the storage box 3 is connected to the cylinder 16, the output shaft of the cylinder 16 is connected to the pressure plate 20, and the pressure plate 20 is slidably connected to the filter frame 22.

[0025] The specific implementation process is as follows:

[0026] During use, the garbage leachate is discharged into the filter box 5 through the water inlet pipe 9 through an external pump. After entering the filter box 5, the garbage leachate is filtered through the filter plate 8 and falls to the bottom of the filter box 5. Impurities roll through the inclined filter plate 8 and fall into the filter frame 22 in the storage box 3 through the first outlet 13 and the second outlet 14. Part of the garbage leachate that falls into the storage box 3 together with the impurities flows to the bottom of the filter box 5 through the reflux pipe 4. At this time, the sealing cover 7 closes the dosing pipe 6. Start the suction pump 15, which extracts the odorous air in the filter box 5 and the storage box 3. The flow of air can be ensured through the balance pipe 11. The odorous gas flows along the air inlet pipe 12 under the action of the suction pump 15, then enters the purification frame 18 through the connecting pipe 17, then moves along the purification frame 18, passes through the adsorption plate and the activated carbon plate 26 in turn, undergoes preliminary purification through the adsorption plate and the activated carbon plate 26, then flows along the air outlet pipe 19, and finally reaches the bottom of the solution tank 2. The gas is ejected from the outlet pipe 19 into the treatment chamber, and is discharged from the surface of the treatment chamber after reacting with the treatment reagent, and then is discharged into the atmosphere through the exhaust pipe 23, completing the purification of the odorous gas. When the garbage leachate is discharged into the filter box 5, the treatment agent can be added into the filter box 5 through the dosing pipe 6. When the garbage leachate falls to the bottom of the filter box 5, it can be mixed with the treatment agent to react and perform preliminary treatment on the garbage leachate. When a certain amount of garbage leachate accumulates at the bottom of the filter box 5, the cylinder 16 is started, and the cylinder 16 drives the pressing plate 20 to move downward. The impurities in the filter frame 22 are squeezed by the pressing plate 20, so that all the garbage leachate attached to the magazine is discharged from the reflux pipe 4 to the filter box 5. Then, the drain pipe can be opened to discharge the garbage leachate at the bottom of the filter box 5. The box door 21 is opened, and the filter frame 22 is slid out to the right to centrally treat the collected impurities. Subsequently, the treatment solvent can be added to the solution box 2 through the exhaust pipe 23. The activated carbon plate 26 or adsorption plate can be directly pulled upward to remove it from the purification frame 18.

During installation, align the adsorption plate with the connecting through hole 28, and then insert the adsorption plate into the purification frame 18 until the sealing pad 29 contacts the side wall of the connecting through hole 28.
