Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wall-mounted deodorization device for wastewater pumping stations with replaceable filter media. Background Technology

[0002] Wastewater pumping stations are key facilities in urban drainage systems, primarily used for lifting and transporting sewage. During the treatment and transport of sewage, the large amounts of organic matter and sulfides in the sewage decompose under anaerobic conditions, producing gases with strong, pungent odors such as hydrogen sulfide, ammonia, and methanethiol. These gases not only affect the quality of life of surrounding residents but may also harm the health of workers and corrode equipment.

[0003] Based on the above, the inventors have discovered the following problems: In order to maintain the deodorization effect, current deodorization devices need to be shut down when the filter material is replaced, and the replacement process is cumbersome and inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a wall-mounted deodorization device for sewage pumping stations with replaceable filter media, in order to achieve a more practical purpose. Utility Model Content

[0006] A wall-mounted deodorization device for sewage pumping stations with replaceable filter media includes a primary filtration assembly. Secondary filtration assemblies are fixedly installed at both ends of the primary filtration assembly, and an exhaust assembly is fixedly installed on the top of the primary filtration assembly. The primary filtration assembly includes a primary filtration chamber, a filter screen is provided on one side of the primary filtration chamber, and a wall-mounted bracket is fixedly installed on the other side of the primary filtration chamber. Two sets of guide rails are fixedly installed at both ends inside the primary filtration chamber. A filter media groove is provided at the bottom between each set of guide rails. A sealing slider is slidably connected to each set of guide rails. The area of ​​the sealing slider is larger than that of the filter media groove. A filter media frame is inserted inside the filter media groove. Primary filter media is provided inside the filter media frame. First magnetic blocks are provided at both ends of the bottom of the sealing slider, and third magnetic blocks are fixedly installed at the top of both ends of the filter media groove.

[0007] By adopting the above technical solution, the exhaust component facilitates the creation of negative pressure inside the device, allowing outside air to enter the primary filter component for primary filtration. After primary filtration, the air enters the secondary filter component for secondary filtration. Finally, after primary and secondary filtration, the air is discharged from the exhaust component, achieving a deodorization effect. The filter screen effectively intercepts larger particles, preventing these impurities from entering the device and extending its service life. The wall-mounted bracket allows for easy mounting on a wall, saving space and facilitating maintenance. The filter media grooves facilitate installation and removal. When replacing the primary filter media, the sealing slider facilitates disassembly and replacement, sealing the filter media tank to prevent external air from entering the device. This allows for filter media replacement without shutting down the system. The primary filter media is made of activated carbon and is used for the initial adsorption of volatile organic compounds and other malodorous gases. The first and second magnetic blocks are magnetically connected to fix the sealing slider at the top of the filter media tank, preventing external air from entering the device and allowing for filter media replacement without shutting down the system.

[0008] Furthermore, a connecting groove is provided at the center of the bottom end of the sealing slider, and the connecting groove is located on the outer side of the top of the filter material frame.

[0009] By adopting the above technical solution and setting the connecting groove, it is convenient to connect the filter media frame and the sealing slider when installing the primary filter media, so that the sealing slider can guide the installation of the primary filter media.

[0010] Furthermore, a second magnetic block is fixedly installed in the middle of the connecting groove, and a fourth magnetic block is fixedly installed in the middle of the top of the filter material frame. The fourth magnetic block is magnetically connected to the second magnetic block.

[0012] Furthermore, an installation strip is fixedly installed at the bottom of the filter media frame, and installation holes are provided at both ends of the installation strip. Installation screws are inserted into the installation holes and are threadedly connected to the bottom of the primary filtration chamber.

[0013] By adopting the above technical solution and using the installation screws, the filter media frame can be securely fixed to the primary filtration chamber, facilitating the filtration of air by the primary filter media inside the primary filtration chamber.

[0014] Furthermore, the secondary filter assembly includes a secondary filter chamber, and a connecting groove is provided on one side of the secondary filter chamber. The connecting groove is located on the side of the guide rail away from the filter screen.

[0015] By adopting the above technical solution and setting up the connecting groove, it is easy to connect the secondary filter chamber with the primary filter chamber, so that the gas that has passed through the primary filter can enter the secondary filter chamber for secondary filtration.

[0016] Furthermore, two connecting pieces are fixedly installed inside the connecting groove, and an adjusting piece is slidably connected between the two connecting pieces. Adjusting grooves are opened on the surface of both the connecting pieces and the adjusting piece.

[0017] By adopting the above technical solution, the setting of the adjustment groove facilitates the sliding of the adjustment plate so that the adjustment groove of the adjustment plate coincides with the adjustment groove of the connecting plate, thereby opening the connecting groove. When the adjustment groove of the adjustment plate and the adjustment groove of the connecting plate intersect each other, the connecting groove is closed, which facilitates the replacement of the secondary filter material inside the secondary filter chamber.

[0018] Furthermore, a sliding groove is provided at the bottom of the connecting groove, and a sliding block is fixedly installed at the bottom end of the adjusting plate, and the sliding block is slidably connected to the sliding groove.

This draws external air into the primary filtration chamber through the filter screen for primary filtration. The gas after primary filtration enters the secondary filtration chamber for secondary filtration, and the gas after secondary filtration and deodorization is discharged from the exhaust port.

[0026] Compared with existing technologies, the beneficial effects of this utility model are as follows: The exhaust assembly facilitates the creation of negative pressure inside the device, allowing external air to easily enter the primary filter assembly for primary filtration. After filtration, the air enters the secondary filter assembly for secondary filtration. After primary and secondary filtration, the air is discharged from the exhaust assembly, achieving a deodorization effect. The filter screen effectively intercepts larger particles, preventing these impurities from entering the device and extending its service life. The wall mount allows for easy mounting on a wall, saving space and facilitating maintenance. The filter media groove facilitates the installation, removal, and replacement of the primary filter media. The sealing slider design... This invention facilitates the removal and replacement of the primary filter media by sealing the filter media tank to prevent external air from entering the device, thus enabling filter media replacement without shutting down the system.
