Description

Technical Field

[0001] This utility model relates to the technical field of odor treatment, and in particular to an odor treatment device for a sewage treatment plant. Background Technology

[0002] With the continuous development and progress of society, industrial production and daily life require a large amount of water resources every day. The protection of the ecological environment and the rational and effective use of resources have become an increasingly important focus of attention. Wastewater after use is transported to sewage treatment plants through municipal sewage pipe networks for purification. Currently, environmental pollution is severe in my country, with the discharge of industrial wastewater and urban domestic wastewater causing environmental pollution.

[0003] Wastewater treatment processes generate significant amounts of odorous gases. Wastewater treatment equipment is primarily used to collect and purify these gases, such as hydrogen sulfide and ammonia. This equipment utilizes physical adsorption and chemical washing to convert harmful components in the odorous gases into harmless substances, ensuring the health of operators and the safety of the ecological environment.

[0004] Currently, most odor treatments rely on filtration. Filtration uses activated carbon and filter materials (such as glass fiber filter cotton and zeolite) to purify the air. However, modern odor purification devices often require timely replacement of the filter materials after prolonged use. Furthermore, after long-term adsorption of odors, the pores of the filter materials become clogged or saturated with chemicals, leading to material hardening, increased weight, and a fragile structure that is prone to breakage during disassembly. When the filter materials break, additional vacuuming equipment is needed to clean the inside of the device, adding extra working time. Utility Model Content

[0005] The purpose of this invention is to provide an odor treatment device for a sewage treatment plant to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] An odor control device for a wastewater treatment plant includes a purification box. A duct is fixedly connected to the top of the purification box, and a connecting pipe is fixedly connected to the bottom of the purification box. A sealed door is hinged to the front of the purification box. A purification grid plate is provided inside the purification box. A fixed frame is fixedly connected to the bottom of the inner wall of the purification box. A cylinder is fixedly connected to one side of the inner wall of the fixed frame. A connecting block is fixedly connected to the top of the telescopic end of the cylinder. A movable strip is connected to one side of the connecting block via a rotating shaft. Three force-bearing movable blocks are rotatably connected to one side of the movable strip via a fixed shaft. A cover plate is fixedly connected to the top of each force-bearing movable block, and a fixed plate is fixedly connected to the bottom of the cover plate. The fixed plate is fixedly connected to the inner wall of the fixed frame via a rotating shaft.

[0008] In some embodiments, a strip is fixedly connected to one side of the cover plate, and a strip groove is provided on the side of the cover plate away from the strip.

[0009] In some embodiments, an extension plate is fixedly connected to the top of the fixed frame.

[0010] In some embodiments, the inner sidewall of the purification box is provided with grooves on both sides, a slider is slidably connected inside the groove, a placement box is fixedly connected to one side of the slider, a purification grid plate is placed inside the placement box, and a plurality of ventilation holes are provided at the bottom of the placement box.

[0011] In some embodiments, the chutes are symmetrically arranged on both sides of the inner wall of the purification box, and the placement box is located above the fixing frame.

[0012] In some embodiments, the three force-bearing movable blocks are arranged at intervals along the length of the moving bar, and a cover plate is fixedly connected to the top of each force-bearing movable block.

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Currently, most odor treatment methods rely on filtration. These methods use activated carbon and filter materials (such as fiberglass filter cotton and zeolite) to purify the air. However, after prolonged use, it is difficult to replace the filter materials in odor purification devices. Furthermore, after long-term adsorption of odors, the pores of the filter materials are easily clogged or saturated with chemicals, leading to material hardening, increased weight, and a fragile structure that is prone to breakage during disassembly. When the filter materials break, additional vacuuming equipment is required to clean the inside of the device, adding extra working time.

[0028] like Figure 1-6 As shown, this utility model embodiment provides an odor treatment device for a sewage treatment plant, including a purification box 1. A duct 101 is fixedly connected to the top of the purification box 1, a connecting pipe 102 is fixedly connected to the bottom of the purification box 1, a sealed box door 103 is hinged to the front of the purification box 1, a purification grid plate 104 is provided inside the purification box 1, a fixed frame 3 is fixedly connected to the bottom of the inner side wall of the purification box 1, a cylinder 4 is fixedly connected to one side of the inner side wall of the fixed frame 3, a connecting block 401 is fixedly connected to the top of the telescopic end of the cylinder 4, a moving strip 402 is connected to one side of the connecting block 401 through a rotating shaft, three force-bearing movable blocks 403 are rotatably connected to one side of the moving strip 402 through a fixed shaft, a cover plate 404 is fixedly connected to the top of the force-bearing movable blocks 403, a fixed plate 405 is fixedly connected to the bottom of the cover plate 404, and the fixed plate 405 is fixedly connected to the inner wall of the fixed frame 3 through a rotating shaft.

[0029] Odors generated by the wastewater treatment plant enter the purification chamber 1 through the connecting pipe 102 at the bottom. The air duct 101 at the top of the purification chamber 1 connects to an external exhaust system (not shown in the diagram). Under the action of the exhaust system, a negative pressure is created inside the purification chamber 1, causing the odors to enter through the connecting pipe 102 and flow upwards. After being purified by the purification mesh plate 104 (containing fiberglass filter cotton, zeolite, activated carbon, etc.) inside the purification chamber 1, the odors are discharged through the air duct 101. The sealed door 103 allows the purification chamber 1 to be opened when needed for convenient maintenance, replacement, and other operations of the internal parts.

[0030] When the purification mesh plate 104 needs to be replaced, the sealed door 103 is opened. To prevent the filter material from hardening and falling off, the cylinder 4 is activated, and its extension end moves to one side, causing the connecting block 401 to move. The connecting block 401 is connected to the moving bar 402 via a rotating shaft, allowing the moving bar 402 to move laterally. Three force-bearing movable blocks 403 are rotatably connected to one side of the moving bar 402 via a fixed shaft. When the moving bar 402 moves, it causes the force-bearing movable blocks 403 to rotate around the fixed shaft. A cover plate 404 is fixedly connected to the top of the force-bearing movable block 403. The bottom of the cover plate 404 is fixedly connected to the inner wall of the fixed frame 3 via a rotating shaft through a fixed plate 405. Driven by the force-bearing movable block 403, the cover plate 404 rotates around the connection between the fixed plate 405 and the inner wall of the fixed frame 3, thereby closing the cover plate 404. When it is necessary to open the cover plate 404 to allow air to circulate, the telescopic end of the cylinder 4 retracts downward, causing the connecting block 401, the moving bar 402, and the force-bearing moving block 403 to move in the opposite direction, causing the cover plate 404 to rotate in the opposite direction around the fixed point, and finally the cover plate 404 opens to facilitate the flow of gas.

[0031] When replacing the purification grid plate 104, the cylinder 4 is activated to move the telescopic end and eventually close the cover plate 404. In this way, when replacing the purification grid plate 104, the closed cover plate 404 can play a collecting and blocking role, preventing debris from falling into the bottom of the purification box 1, which facilitates the subsequent centralized cleaning of debris, reduces the pollution inside the device and the difficulty of subsequent cleaning.

[0032] Furthermore, a strip 5 is fixedly connected to one side of the cover plate 404, and a strip groove 501 is provided on the side of the cover plate 404 away from the strip 5.

[0033] When the three cover plates 404 are closed, adjacent cover plates 404 cooperate with each other, and the strip 5 on one cover plate 404 inserts into the strip groove 501 on the other cover plate 404. Since the strip groove 501 and the cover plate 404 are the same size and fit each other, the strip 5, after being inserted into the strip groove 501, can fill the gap between adjacent cover plates 404. This effectively prevents debris from falling from the gap between the cover plates 404.

[0034] Furthermore, an extension plate 301 is fixedly connected to the top of the fixed frame 3.

[0035] The extension plate 301 is horizontally fixed to the top of the fixing frame 3. When the cover plate 404 is closed, the debris falling from the purification grid plate 104 will fall directly onto it, forming a centralized collection area. This prevents debris from scattering to other parts of the equipment and facilitates subsequent cleaning.

[0036] Furthermore, the inner sidewall of the purification box 1 is provided with sliding grooves 2 on both sides, and a slider 201 is slidably connected inside the sliding groove 2. A placement box 202 is fixedly connected to one side of the slider 201. A purification grid plate 104 is placed inside the placement box 202, and multiple ventilation holes 203 are provided at the bottom of the placement box 202.

[0037] The sliders 201 on both sides of the placement box 202 slide inside the slide groove 2, allowing the placement box 202 to slide along the slide groove 2 via the sliders 201. When it is necessary to install or replace the purification mesh plate 104 inside the placement box 202, the sealed box door 103 can be opened to slide the placement box 202 out of the slide groove 2; after installation or replacement, the placement box 202 is slid back into the slide groove 2 so that it is positioned above the fixing frame 3.

[0038] The purification grid plate 104 is placed inside the placement box 202 and can be pulled out by sliding the slider 201 in the slide groove 2. The vent 203 ensures airflow.

[0039] Furthermore, the chute 2 is symmetrically arranged on both sides of the inner wall of the purification box 1, and the placement box 202 is located above the fixing frame 3.

[0040] The symmetrically arranged slides 2 ensure smooth movement of the placement box 202, and the placement box 202, positioned above the fixed frame 3, provides better support.

[0041] Furthermore, the three force-bearing movable blocks 403 are arranged at intervals along the length of the moving bar 402, and a cover plate 404 is fixedly connected to the top of each force-bearing movable block 403.

[0042] When the telescopic end of cylinder 4 drives the moving bar 402 to move, the three force-bearing movable blocks 403 are simultaneously subjected to force, which respectively drive the cover plates 404 connected to them to rotate around the fixed point, thereby realizing the opening and closing of the three cover plates 404.

[0043] Furthermore, the purification grid plate 104 is horizontally arranged inside the placement box 202 and is perpendicular to the airflow direction of the air duct 102 and the connecting pipe 101.

[0044] This ensures that the odorous gases are in full contact with the purification grid plate 104, thus improving the purification efficiency of the odorous gases.

[0045] Furthermore, the strip groove 501 and the cover plate 404 are the same size and fit each other. The strip piece 5 fits into the strip groove 501, filling the gap between adjacent cover plates 404.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
