Description

Technical Field

[0001] This utility model relates to the field of landfill leachate technology, specifically to a replaceable filter cartridge device for landfill leachate purification. Background Technology

[0002] Landfill leachate is a highly concentrated and polluting organic wastewater produced during the landfilling, stockpiling, or treatment of waste due to precipitation, microbial decomposition, and compression. Its composition is complex, containing a large number of toxic and harmful substances. If discharged directly without treatment, it will cause serious damage to soil, groundwater, and the ecological environment.

[0003] Currently, landfill leachate is generally collected and extracted for purification. During purification, it needs to be filtered. However, because a large amount of garbage and impurities remain in the landfill leachate, these impurities can clog the filter screen. Current purification equipment is quite troublesome to disassemble and install the filter screen and handle the impurities, which affects the purification efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a replaceable filter cartridge device for landfill leachate purification, which can quickly push out internal impurities by rotation and quickly replace its filter screen, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a replaceable filter cartridge device for landfill leachate purification, comprising a housing, wherein multiple partitions are installed inside the housing, and filtration channels are formed between adjacent partitions and between the partitions and the housing. A strip-shaped opening is provided on one side of the housing facing the filtration channel, and a cover plate is provided in each strip-shaped opening to seal the opening. A frame is provided on the inner side of each cover plate, and a filter screen is installed inside each frame. A shaft is installed on one side of the multiple cover plates to drive the cover plates and the frame to rotate synchronously. Multiple inclined rods are installed on the side of the housing facing the cover plates, and the inclined rods are all positioned to face the gaps between the cover plates.

[0006] As a preferred technical solution, fixing plates are installed on both sides of the housing, and sealed bearings are embedded in both fixing plates. Both ends of the shaft are installed in the inner ring of the sealed bearings, and a brake motor connected to the shaft is installed on one side of the fixing plate.

[0007] As a preferred technical solution, a cover is installed at one end of the housing, and multiple liquid inlet pipes are installed on the cover facing the filter channel, while the other end of the housing is left open.

[0008] As a preferred technical solution, one end of the frame is in contact with the inner side of the cover plate, and the other end is in contact with the inner side of the housing. Multiple insertion holes are provided on the side of the frame facing the cover plate. Insert rods are installed on the inner side of the cover plate opposite the insertion holes. The insertion rods are inserted into the insertion holes and are in frictional contact with the insertion holes.

[0009] As a preferred technical solution, connecting seats are installed on both sides of the housing, and the connecting seats are provided with multiple straight slots.

[0010] As a preferred technical solution, the length of the frame is shorter than the length of the cover plate.

[0011] As a preferred technical solution, the length and width of the frame match the length and width of the filter channel.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure. The motor can drive the shaft to rotate, and the shaft can synchronously drive the cover plate and the frame to rotate. The rotating frame can push out residual impurities and allow the cover plate to enter between the inclined rods. The inclined rods and the cover plate can combine to form a guide plate, allowing the pushed impurities to be discharged along the guide plate. After pushing the frame upward, the frame can be directly removed from the cover plate, which facilitates disassembly and assembly and greatly reduces the difficulty of replacement.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a replaceable filter cartridge device for landfill leachate purification, comprising a housing 1. Multiple partitions 10 are installed inside the housing 1, forming filtration channels between adjacent partitions 10 and between the partitions 10 and the housing 1. A strip-shaped opening is provided on one side of the housing 1 facing the filtration channel, and a cover plate 2 is provided in each of the strip-shaped openings to seal them. A frame 11 is provided on the inner side of each cover plate 2, and a filter screen 12 is installed inside each frame 11. A shaft 3 is installed on one side of each of the multiple cover plates 2 to drive the cover plates 2 and the frame 11 to rotate synchronously. Multiple inclined rods 4 are installed on the side of the housing 1 facing the cover plates 2, and the inclined rods 4 are positioned directly opposite the gaps between the cover plates 2.

[0023] In this embodiment, fixing plates 5 are installed on both sides of the housing 1, and sealed bearings are embedded in the fixing plates 5. Both ends of the shaft 3 are installed in the inner ring of the sealed bearings. A brake motor 6 connected to the shaft 3 is installed on one side of the fixing plate 5. The brake motor is controlled by a microcontroller and connected to a power supply. It can be programmed and controlled by the microcontroller.

[0024] In this embodiment, a cover 8 is installed at one end of the housing 1, and multiple liquid inlet pipes 9 are installed on the cover 8 opposite the filter channel. The other end of the housing 1 is left open.

[0025] In this embodiment, one end of the frame 11 is in contact with the inner side of the cover plate 2, and the other end is in contact with the inner side of the housing 1. The frame 11 is provided with a plurality of insertion holes 13 on the side facing the cover plate 2. Insert rods 14 are installed on the inner side of the cover plate 2 opposite to the insertion holes 13. The insertion rods 14 are inserted into the insertion holes 13 and are in frictional contact with the insertion holes 13.

[0026] In this embodiment, connecting seats 7 are installed on both sides of the housing 1, and the connecting seats 7 are provided with multiple straight slots.

[0027] In this embodiment, the length of the frame 11 is shorter than the length of the cover plate 2, so that the frame can pass smoothly through the strip opening and rotate to the outside; the length and width of the frame 11 match the length and width of the filter channel, so that the outer side of the frame can contact the inner wall of the filter channel to ensure its sealing after installation.

[0028] Working principle: The extracted leachate enters the filtration channel through the inlet pipe and comes into contact with each filter screen. The filter screen filters out the impurities inside, leaving them in the filtration channel, while the liquid is discharged from the filter screen until it flows out from the opening at the other end of the shell.

[0029] As attached Figure 4 As shown, after a long period of purification, impurities in the filter channel will accumulate on the surface of the filter screen, resulting in a reduction in purification efficiency. At this time, the brake motor can be activated. The activation of the brake motor drives the shaft, and the rotation of the shaft drives the cover plate and the frame, causing the cover plate and the frame to move out of the strip-shaped opening in sequence. The cover plate can enter between the inclined rods, and the cover plate and the inclined rods can combine to form an inclined guide plate, so that the impurities falling from the frame and the filter screen can be discharged downward along the guide plate in a unified manner, which facilitates subsequent collection.

[0030] After the frame is removed from the housing, it can be pulled upwards to remove it from the insert rod, facilitating disassembly. Once the new frame is inserted into the insert rod, the rotation of the brake motor moves the frame back to its original position, with the other end of the frame abutting against the inner wall of the housing, preventing lateral movement and ensuring the stability of the frame and filter installation.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
