Description

Technical Field

[0001] This utility model relates to the field of odor treatment and purification technology for sewage ponds, specifically a biological deodorization box with filtration function. Background Technology

[0002] The stench from sewage ponds is extremely harmful. To the human body: the stench affects the respiratory, digestive, cardiovascular, endocrine, and nervous systems. High concentrations of stench can cause pulmonary edema and even suffocation. Odor pollution is often accompanied by substances that are directly harmful to humans, such as formaldehyde and benzene, which have strong carcinogenic effects when inhaled.

[0003] According to a public notice of a biological deodorization box (Announcement No.: CN216024108U), the above application includes a deodorization structure that uses microbial decomposition technology to avoid or reduce secondary pollution. The mixed packing material is a mixture of organic and inorganic materials in a honeycomb shape, which has good permeability and structural stability, ensuring minimal pressure loss even after long-term operation. Furthermore, the filter chamber has a large buffer capacity, which can adapt to the impact of peak exhaust gas concentrations and achieve high treatment efficiency.

[0004] However, in actual use, the odorous gas used for deodorization often passes through easily passable filter mesh over long-term use. This overloads the filter plate and reduces its filtration efficiency. Furthermore, the odorous gas cannot be adequately filtered by passing through a simple air duct, and the filter cannot be installed, disassembled, or regularly maintained or replaced. Therefore, we propose a biological deodorization box with filtration function. Utility Model Content

[0005] The purpose of this invention is to provide a biological deodorizing box with filtration function to solve the problems mentioned in the background art.

[0007] The air intake chamber has two sets of partitions fixedly connected to the bottom surface of the deodorizing box. The gap between the partitions and the inner wall of the deodorizing box on the side of the air inlet forms the air intake chamber. The air intake chamber is connected to the air inlet. The gap between the two sets of partitions is set as the installation chamber. The gap between the partitions and the inner wall of the deodorizing box on the side away from the air inlet forms the exhaust chamber. The side wall of the installation chamber is slidably connected to a first filter box. The end of the first filter box near the air inlet has an air inlet groove.

[0008] A filter plate is provided, the bottom surface of which is fixedly connected to the bottom surface of the first filter box. A second filter box is attached to the side wall of the first filter box, and a third filter box is attached to the side of the second filter box away from the first filter box.

[0015] Compared with the prior art, this utility model provides a biological deodorization box with filtration function, which has the following beneficial effects:

[0016] 1. This biological deodorizing box with filtration function, through its optimized airflow path and multi-stage filtration design, significantly improves deodorization and filtration efficiency. Specifically, after air enters the air intake chamber through the air inlet, it flows sequentially through the first, second, and third filter boxes. Each filter box has a fixedly connected "<"-shaped filter plate at its bottom, forming a continuous "S"-shaped airflow channel, forcing the air to flow in a tortuous manner and extending the contact time. Simultaneously, the filter screens in the air intake and exhaust chambers, along with the activated carbon filter box in the exhaust chamber, work together to achieve step-by-step interception and adsorption of odor molecules and particulate matter. This structure not only enhances the utilization rate of the biological filter material but also ensures uniform airflow distribution, effectively removing odors and preventing filtration dead zones, making it suitable for high-concentration odor environments.

[0017] 2. This biological deodorizing box with filtration function simplifies the maintenance and replacement process of the filter components by setting up an auxiliary mechanism, which improves the ease of operation. The limiting groove on the side wall of the installation chamber and the circular groove on the partition cooperate with the fixing column on the side wall of the filter box to ensure that the first, second and third filter boxes are accurately positioned and stable when sliding. At the same time, the convenient handle on the inner wall of each filter box allows users to quickly disassemble and install the components without tools. This design reduces maintenance downtime and reduces the intensity of operation, making it particularly suitable for scenarios where filter boxes are frequently cleaned or replaced, ensuring long-term efficient operation of the equipment.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a biological deodorizing box with filtration function, including a deodorizing box 1, a cover plate 11 detachably connected to the upper surface of the deodorizing box 1, an air inlet 13 provided on one side of the deodorizing box 1, and a filtration mechanism 2 provided inside the deodorizing box 1. The filtration mechanism 2 includes: an air inlet chamber 21, an installation chamber 22, an exhaust chamber 23, a first filter box 24, a second filter box 25, a third filter box 26, an air inlet groove 27, a ventilation groove 28, an exhaust groove 29, a filter screen 210, an activated carbon filter box 211, and a filter plate 212.

[0024] In one embodiment of this utility model, two sets of partitions are fixedly connected to the inner bottom surface of the deodorizing box 1. The gap between the partitions and the inner wall of the deodorizing box 1 on the side of the air inlet 13 forms an air inlet chamber 21, which communicates with the air inlet 13. The gap between the two sets of partitions is set as an installation chamber 22. The gap between the partitions and the inner wall of the deodorizing box 1 on the side away from the air inlet 13 forms an exhaust chamber 23. A first filter box 24 is slidably connected to the side wall of the installation chamber 22. An air inlet groove 27 is opened at the end of the first filter box 24 near the air inlet 13. The bottom surface of the filter plate 212 is connected to the first filter box. The bottom surface of filter box 24 is fixedly connected. The side wall of filter box 24 is attached to filter box 25. The side of filter box 25 away from filter box 24 is attached to filter box 26. Filter plates 212 are fixedly connected to the bottom surfaces of filter boxes 25 and 26. Ventilation groove 28 is opened on the side wall of filter box 24 away from air inlet groove 27. Ventilation groove 28 is opened on the side wall of filter box 25 near air inlet groove 28. Exhaust groove 29 is opened on the end of filter box 26 away from air inlet 13. The inner surfaces of air inlet groove 27 and exhaust groove 29 are... All are fixedly connected with filter screens 210. An activated carbon filter box 211 is fixedly connected to the inner surface of the exhaust chamber 23. The filter plate 212 is shaped like a "<" and forms an "S" shaped air passage through the first filter box 24, the second filter box 25, and the third filter box 26. The air inlet side of the filter plate 212 is set to face the air inlet 13. By setting the filter mechanism 2, the air flow path and the multi-filtration design are optimized, which significantly improves the deodorization and filtration efficiency. Specifically, after the air enters the intake chamber 21 from the air inlet 13, it flows through the first filter box 24, the second filter box 25, the third filter box 26, and the third filter box 26 in sequence. The filter box 25 and the third filter box 26, with "<" shaped filter plates 212 fixedly connected to the bottom of each filter box, form a continuous "S" shaped air passage, forcing the air to flow in a tortuous manner and prolonging the contact time; at the same time, the filter screens 210 of the air inlet slot 27 and the exhaust slot 29, as well as the activated carbon filter box 211 in the exhaust chamber 23, work together to achieve step-by-step interception and adsorption of odor molecules and particulate matter. This structure not only enhances the utilization rate of the biological filter material, but also ensures uniform airflow distribution, thereby effectively removing odors and preventing filtration dead zones, making it suitable for high-concentration odor environments.

[0025] In addition, an auxiliary mechanism 3 is provided on the side wall of the installation chamber 22. The auxiliary mechanism 3 includes a limiting groove 31. The limiting groove 31 is formed on the side wall of the installation chamber 22. A circular groove 32 is formed on the side of the partition away from the outer wall of the deodorizing box 1. The side walls of the first filter box 24, the second filter box 25 and the third filter box 26 are all fixedly connected to the fixing posts 34, and the inner walls of the first filter box 24, the second filter box 25 and the third filter box 26 are all fixedly connected to the convenient handles 33. By providing the auxiliary mechanism 3, the maintenance and replacement process of the filter mechanism 2 is simplified. The ease of operation is improved by aligning the limiting groove 31 on the side wall of the installation chamber 22 and the circular groove 32 on the partition with the fixing post 34 on the side wall of each filter box. This ensures that the first filter box 24, the second filter box 25, and the third filter box 26 are accurately positioned and stable during sliding connection. At the same time, the convenient handle 33 on the inner wall of each filter box allows users to quickly disassemble and install components without tools. This design reduces maintenance downtime and lowers the intensity of operation, making it particularly suitable for scenarios where filter boxes are frequently cleaned or replaced, ensuring long-term efficient operation of the equipment.

[0026] In this embodiment of the utility model, a latch 12 is fixedly connected to the side wall of the cover plate 11, and a corresponding keyhole is provided on the outer wall of the deodorizing box 1. Through the cooperation of the latch 12 and the keyhole, the cover plate 11 can be easily opened and closed, which makes it easier for staff to maintain, repair, and replace the filter mechanism 2. A water pump 4 is fixedly connected to the upper surface of the cover plate 11, and a water distribution pipe 41 is fixedly connected to the output end of the water pump 4. A water supply pipe 42 is fixedly connected to the side of the water distribution pipe 41 away from the water pump 4, and the lower surface of the water supply pipe 42 is fixedly connected to... The device is equipped with a hidden nozzle. Water pump 4 draws external water and microorganisms into the device and sprays them onto the filter plate 212, allowing the filter mechanism 2 to work for a longer period of time and ensuring its working efficiency. At the same time, an air pump 5 is fixedly connected to the upper surface of the cover plate 11. The output end of the air pump 5 is fixedly connected to the exhaust port 51, and the input end of the air pump 5 passes through the cover plate 11 and communicates with the exhaust chamber 23. By setting up the air pump 5, the odor can be assisted to flow in the air passage, which can accelerate the odor purification efficiency.

[0027] In this invention, during use, the odor first enters the air intake chamber 21 through the air inlet 13, and then enters the interior of the first filter box 24 through the air intake groove 27. The gas is intercepted and preliminarily treated by the filter plates 212 inside the box, and then enters the adjacent second filter box 25 and third filter box 26 sequentially through the ventilation groove 28, continuously receiving purification from each level of filter plates 212 in a tortuous "S" shaped path. The gas that has completed multi-stage filtration flows out from the exhaust groove 29 of the third filter box 26 and enters the exhaust chamber 23, where it is further treated by the adsorption of the activated carbon filter box 211. Finally, the purified gas is drawn out by the suction of the air pump 5 and discharged outside the box through the exhaust port 51. In addition, the water pump 4 can spray nutrient solution or microbial preparation into the box through the water distribution pipe 41 and the water supply pipe 42 to maintain the biological filtration activity or clean the filter material.
