Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically a landfill leachate filtration device. Background Technology

[0002] Landfill leachate is a high-concentration organic wastewater formed from the moisture contained in the landfill itself, rainwater and snowmelt entering the landfill, and other moisture, after deducting the saturated water holding capacity of the landfill and the topsoil layer, and passing through the landfill and topsoil layers. This leachate can cause serious environmental pollution, so it needs to be treated by equipment, and filtration devices are one type of treatment equipment.

[0003] Utility model CN209752285U discloses a landfill leachate filtration device, including a shell with an inlet at the top and an outlet at the bottom. A filter screen is housed inside the shell, and a protrusion protrudes from the side of the shell, with a cleaning port communicating with the interior of the shell. A sealing block is located within the protrusion to open or seal the cleaning port. A driving component is provided between the sealing block and the filter screen; when the cleaning port is open, the filter screen tilts towards the cleaning port via the driving component. This utility model achieves the purpose of cleaning by tilting the filter screen and rinsing it with clean water, directly flushing impurities from the filter screen through the cleaning port. However, it requires stopping filtration before cleaning the filter screen, reducing filtration efficiency. Utility Model Content

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1-8 This is the first embodiment of the present utility model. This embodiment provides an example of a landfill leachate filtration device, including a main body 101, an inlet 102 at the top of the main body 101, and two symmetrical outlets 201 at the bottom of the main body 101, with the outlets 201 connected to the inlet 102.

[0030] Two symmetrical filter tanks 106 are provided on one side of the main body 101. The filter tanks 106 pass through the water outlet 201. A detachable filter mechanism 105 is provided inside the water outlet 201. A partition shaft 104 is rotatably provided between the two sides of the water inlet 102. One side of the partition shaft 104 extends to the outside of the main body 101. A movable partition 103 is fixedly provided on the outer wall of the partition shaft 104 inside the water inlet 102.

[0031] Wastewater entering the inlet 102 is diverted by the movable baffle 103 and flows into two outlets 201. It is filtered by the filter mechanism 105 inside the outlet 201. When the filter mechanism 105 needs to be cleaned or replaced, the baffle shaft 104 can be rotated, which in turn drives the movable baffle 103 to rotate. The movable baffle 103 then blocks one outlet 201, thus guiding the flow. This allows the wastewater to flow only into one outlet 201, making the filter mechanism 105 on the other side disassembled and cleaned. This allows the filter mechanism 105 to be cleaned and replaced without stopping filtration, thereby improving work efficiency.

[0032] Example 2

[0033] Reference Figure 1-8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a tensioning cavity 200 is provided inside the movable partition 103. Symmetrical return blocks 107 are fixed on both sides of the movable partition 103. A tensioning opening 209 is provided between the water inlet 102 and the tensioning cavity 200 through the return blocks 107. A rotating shaft 203 is rotatably provided between the two walls of the tensioning cavity 200. A tensioning wheel 300 is fixed on the outer wall of the rotating shaft 203. A movable return plate 108 is provided inside the tensioning opening 209. The return plate 108 extends into the water inlet 102. A tensioning rope 208 is connected between the two return plates 108. The tensioning rope 208 is tensioned by the tensioning wheel 300.

[0034] When the movable baffle 103 is diverting the flow normally, the return plates 108 on both sides move towards the outlet 201 under their own weight, thereby preventing sewage from scouring the baffle shaft 104 and increasing its service life. When the movable baffle 103 turns to one side to guide the flow, it will drive the return block 107 to rotate, thereby causing the return plate 108 to contact the side wall of the outlet 201. This causes the return plate 108 on one side to move closer to the tensioning cavity 200, and the return plate 108 on the other side to move away from the tensioning cavity 200, thereby preventing sewage in the outlet 201 from flowing back into the partitioned outlet 201 and thus preventing sewage leakage.

[0035] Example 3

[0036] Reference Figure 1-8This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a spring cavity 206 is provided in the side wall of the outlet 201 away from the partition shaft 104. A movable spring plate 202 is provided in the spring cavity 206. A locking groove 204 is provided through the side of the filter mechanism 105 away from the partition shaft 104. A locking plate 205 is fixedly provided on the side of the spring plate 202 near the partition shaft 104. The locking plate 205 extends into the spring cavity 206. An upper top block 109 is fixedly provided on the side of the spring plate 202 away from the partition shaft 104. The upper top block 109 extends into the inlet 102. A translation spring 207 is provided between the side of the spring plate 202 away from the filter tank 106 and the side wall of the spring cavity 206 away from the filter tank 106.

[0037] Under the action of the translation spring 207, the spring plate 202 moves towards the inlet 102, thereby driving the upper block 109 to move into the inlet 102. At the same time, it drives the locking plate 205 to move into the locking groove 204, thereby fixing the filter mechanism 105 and preventing the filter mechanism 105 from being accidentally pulled out during operation, which would cause sewage to flow out. When it is necessary to remove the filter mechanism 105 for cleaning and replacement, first rotate the movable partition 103. When the movable partition 103 completely blocks the outlet 201 on one side, it will press the upper block 109 towards the spring cavity 206, thereby causing the spring plate 202 to move towards the spring cavity 206, thereby causing the locking plate 205 to move towards the spring cavity 206, thereby causing the locking plate 205 to leave the locking groove 204, and thus allowing the filter mechanism 105 to be pulled out.

[0038] The above are only specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of this utility model are covered by the patent scope of this utility model.
