Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 In the embodiments of the utility model, a garbage leachate sewage treatment device with deodorization function comprises:

[0023] A plurality of ground rails 100 capable of adjusting the position of the sediment tank 110, a suction mechanism 200 capable of sucking the liquid inside the sediment tank 110, and an adjusting mechanism 400 capable of adjusting the position of the membrane element 430 so that different membrane elements 430 perform sewage filtration operations in turn, the plurality of ground rails 100 are arranged parallel to each other, the sediment tank 110 is slidably connected above the plurality of ground rails 100, and a plurality of partition plates 120 are fixedly connected inside the sediment tank 110, the suction mechanism 200 is located on one side of the sediment tank 110, the adjusting mechanism 400 is located on one side of the suction mechanism 200, the adjusting mechanism 400 comprises a bottom plate 410, and the top surface of the bottom plate 410 is fixedly connected with a support plate at each corner, a drive roller 411 is rotatably connected between any two support plates located on the same side of the bottom plate 410, a cylinder 420 is arranged above the bottom plate 410, and the outer side wall of the cylinder 420 is in contact with the outer side wall of the two drive rollers 411, a plurality of arc-shaped clamping plates 421 are fixedly connected to the inner side wall of the cylinder 420, and a membrane element 430 is arranged at the inner arc surface of any arc-shaped clamping plate 421.

[0024] Specifically, the membrane element 430 is a DTRO membrane column. By injecting sewage from the inlet of the membrane element 430, the filtered permeate can be discharged from the outlet, and the concentrated liquid can be discharged, thereby treating the landfill leachate and separating and treating impurities such as suspended solids, dissolved solids, and dissolved oxygen in the landfill leachate. The inside of the sediment tank 110 is divided into different compartments by a plurality of partition plates 120. During use, the sediment tank 110 is slid to below the sewage pipe by the ground rail 100, and different compartments are used to hold sewage. Then, a flocculating agent is manually added to allow the sewage in the sediment tank 110 to be pretreated by sedimentation. When the amount of sewage is small and dispersed, the sediment tank 110 can separate the sewage by using multiple compartments. When the sewage in one compartment is allowed to settle, other compartments can be used to hold subsequent sewage. The sedimented sewage can be transported to the membrane element 430 at the bottom of the adjusting mechanism 400 by the suction mechanism 200 for filtration treatment. The position of the membrane element 430 can be adjusted by rotating the cylinder 420, so that multiple membrane elements 430 are used alternately. The unused membrane element 430 can be manually disassembled for cleaning, so that the user can replace the membrane column conveniently. When the membrane column is replaced, other membrane columns can be used to continuously treat the sewage, which does not easily affect the efficiency of sewage treatment.

[0025] Embodiment one

[0026] As Figures 2-3As shown, in the embodiment, the bottom plate 410 is provided with a motor box 412, and the motor box 412 is internally provided with a driving motor, the motor shaft of the driving motor is fixedly connected with one end of the adjacent driving roller 411, one end of the cylinder 420 is fixedly connected with an X-shaped connecting plate, and the side center of the connecting plate is fixedly connected with a sleeve 440, the sleeve 440 is slidingly connected with two sliding plates 441, any film element 430 is provided with an arc-shaped pressing plate 450, both ends of any arc-shaped pressing plate 450 are rotatably connected with a supporting arm 451, one end of the two supporting arms 451 on any arc-shaped pressing plate 450 is rotatably connected with the outer side wall of the two sliding plates 441, one end of the sleeve 440 is rotatably connected with a bidirectional screw rod 442, one side of the two sliding plates 441 is provided with a screw hole, and the two screw holes are screw-coupled with the outer side wall of the bidirectional screw rod 442, the bidirectional screw rod 442 is a positive and negative tooth screw rod, one end of the bottom plate 410 is fixedly connected with an L-shaped plate, one end of the L-shaped plate is fixedly connected with an electric push rod 300, the movable end of the electric push rod 300 is fixedly connected with a fixed plate, one side of the fixed plate is provided with a plurality of circular holes, any circular hole is internally fixedly connected with a plug pipe 310, and the other end of the bottom plate 410 is fixedly connected with a baffle.

[0027] In the embodiment, the adjacent driving rollers 411 can be driven to rotate by starting the driving motor. Since the cylinder 420 is supported by the two driving rollers 411, the driving rollers 411 can drive the cylinder 420 to rotate synchronously when the driving rollers 411 rotate. The surface of the driving roller 411 is covered with a rubber layer to improve the friction with the cylinder 420. The outer wall of the sleeve 440 is provided with two cutting grooves. The slide plate 441 is provided with two clamping holes on one side and can be sleeved on the sleeve 440. The film element 430 is placed in the arc-shaped clamping plate 421, and then the two slide plates 441 are driven to move towards each other by rotating the bidirectional screw rod 442. The two slide plates 441 can drive the plurality of arc-shaped pressing plates 450 to move away from the sleeve 440 synchronously and fix the film element 430 in the adjacent arc-shaped clamping plate 421, so as to adapt to film elements 430 with different diameters. When the film element 430 is fixed, the fixed plate can be driven to move by the electric push rod 300, so that the plurality of insertion tubes 310 are sleeved on the inlet, the permeate outlet and the concentrated liquid outlet of the lowermost film element 430. The suction mechanism 200 is connected with the insertion tube 310 at the inlet through a hose, and then the insertion tubes 310 at the permeate outlet and the concentrated liquid outlet are connected with different hoses to discharge the concentrated liquid and the permeate. When it is necessary to take out the unused film element 430, the two slide plates 441 are driven to move slightly away from each other by rotating the bidirectional screw rod 442. The plurality of arc-shaped pressing plates 450 no longer press the film element 430 on the adjacent arc-shaped clamping plate 421, and then the film element 430 is manually taken out from the gap between the arc-shaped clamping plate 421 and the arc-shaped pressing plate 450. When the lowermost film element 430 is in a use state, the lowermost film element 430 is not easy to be taken out from the adjacent arc-shaped clamping plate 421 due to the blocking of the baffle and the limiting of the adjacent arc-shaped clamping plate 421 and the arc-shaped pressing plate 450.

[0028] As shown in Figure 1 and Figure 4 In the embodiment, the suction mechanism 200 comprises:

[0029] The box body 210, a plurality of L-shaped pipes 220 capable of sucking sewage from the inside of the sediment tank 110, a connecting box 230 and a gas cylinder 240. The short arm of each L-shaped pipe 220 is fixedly connected to one side of the box body 210. Each L-shaped pipe 220 is provided with an electromagnetic valve 221. The bottom end of the long arm of any L-shaped pipe 220 is movably sleeved with a sleeve ring 222. The inner wall of any sleeve ring 222 is fixedly sleeved with a filter screen 223. The connecting box 230 is fixedly connected to the other side of the box body 210 through a support. The connecting box 230 is provided with a suction pump inside. The inlet end of the suction pump is fixedly connected to the other side of the box body 210 through a pipeline, and the outlet end is fixedly connected to the adjacent insertion tube 310 through a hose. The gas cylinder 240 is fixedly connected to one side of the sediment tank 110. The movable end of the gas cylinder 240 is fixedly connected to the box body 210.

[0030] In practice, multiple L-shaped pipes 220 are located in different compartments inside the sedimentation tank 110. By activating the solenoid valve 221, the adjacent L-shaped pipes 220 are kept unobstructed, ensuring that only the L-shaped pipes 220 located in the sedimentation compartment are unobstructed. Then, the suction pump is activated to pump the sedimented wastewater into the box 210 through the unobstructed L-shaped pipes 220 and discharge it to the adjacent insertion pipe 310 through the hose. This allows the wastewater to enter the inlet of the membrane element 430 through the insertion pipe 310. The cylinder 240 can be activated to adjust the depth of the bottom of the L-shaped pipe 220 inside the sedimentation tank 110, and the flocculent in the water is blocked by the filter screen 223, which is hemispherical.

[0031] Example 2

[0032] Based on Example 1, the sealing tube is provided to improve the sealing performance between the insertion tube 310 and the membrane element 430.

[0033] like Figure 3 As shown, in this embodiment, a sealing tube is fixedly connected to one end of any insertion tube 310.

[0034] In specific implementation, the inner diameter of the sealing tube can be customized according to the inlet diameter, concentrate outlet diameter, and permeate outlet diameter of the membrane element 430, so that the inner diameter of the sealing tube is equal to the diameter of the inlet, concentrate outlet, or permeate outlet of the inserted membrane element 430. One end of the sealing tube is rounded, so that when the insertion tube 310 is inserted into the inlet, concentrate outlet, or permeate outlet of the membrane element 430, its own sealing tube can be tightly attached to the inlet, concentrate outlet, or permeate outlet of the membrane element 430 to avoid liquid leakage. The sealing tube is made of rigid plastic and is covered with a rubber layer.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
