Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas treatment device with a cleaning structure. Background Technology

[0002] Waste gas treatment devices are specialized equipment used to purify harmful gases generated in industrial production, vehicle exhaust, and laboratory settings. Their core objective is to convert pollutants into harmless substances through physical, chemical, or biological means. Activated carbon adsorption devices are one type of waste gas treatment device; they utilize the porous structure of activated carbon to adsorb organic compounds such as benzene and formaldehyde, achieving purification through physical interception.

[0003] During long-term operation, activated carbon adsorption devices accumulate a large amount of impurities and dust in the primary filter at the air inlet, affecting filtration efficiency. Since traditional primary filters are fixed inside the air inlet, they are inconvenient for users to clean, increasing equipment downtime. Therefore, there is an urgent need for a waste gas treatment device with a cleaning mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste gas treatment device with a cleaning structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste gas treatment device with a cleaning structure includes a waste gas treatment device body. An air inlet seat is fixedly installed on one side of the waste gas treatment device body. A filter screen assembly is fixedly installed in the air inlet channel of the air inlet seat. A brushing chamber is opened on one side of the filter screen assembly in the air inlet seat, and a cleaning plate is vertically movably arranged in the brushing chamber. A brush plate is movably arranged in the cleaning plate. Rotating columns are rotatably arranged on both sides of the top of the cleaning plate through bearings. Each rotating column is fixedly fitted with a clamping piece, and a corresponding clamping cavity is opened on the inner wall of the brushing chamber.

[0007] In addition, in a preferred structure, both ends of the brush plate are fixedly provided with upright plates, and the cleaning plate is provided with adjustment cavities corresponding to the upright plates, and multiple guide rods for guiding the upright plates are fixedly provided in the adjustment cavities.

[0008] In addition, a preferred structure is that each of the upright plates has a guide post fixedly installed on its top, and the guide post is adapted to the guide plate.

[0009] In addition, a preferred structure is that the top of each of the upright plates has multiple spring cavities that face downwards, each spring cavity has a spring installed facing upwards, and the other end of each spring is connected to the horizontal plate.

[0010] In addition, a preferred structure is that each of the rotating columns is fixedly provided with a top member, and the top member is adapted to be located at the bottom of the horizontal plate.

[0011] Furthermore, in a preferred configuration, each of the top members is provided with a long limiting cavity and a short limiting cavity, and both the long limiting cavity and the short limiting cavity are adapted to the horizontal plate.

[0012] The beneficial effects of this utility model are as follows: the exhaust gas treatment device body can treat exhaust gas, the cleaning plate can be fixed by the mutual locking between the clip and the clip cavity, and the filter screen assembly can be cleaned by the setting of the brush plate. This method of cleaning the filter screen assembly does not require disassembling the filter screen assembly, saving time. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-8 A waste gas treatment device with a cleaning structure includes a waste gas treatment device body 1. An air inlet seat 2 is fixedly installed on one side of the waste gas treatment device body 1. A filter screen assembly 22 is fixedly installed in the air inlet channel of the air inlet seat 2. A brushing chamber 21 is opened in the air inlet seat 2 on one side of the filter screen assembly 22, and a cleaning plate 3 is vertically movably arranged in the brushing chamber 21. A brush plate 31 is movably arranged in the cleaning plate 3. Rotating columns 4 are rotatably arranged on both sides of the top of the cleaning plate 3 through bearings. Each rotating column 4 is fixedly fitted with a clamp 41, and a clamping cavity 23 is adapted to fit the clamp 41 on the inner wall of the brushing chamber 21.

[0024] The brush plate 31 has upright plates 32 fixedly mounted at both ends, and each upright plate 32 in the cleaning plate 3 has an adjustment cavity 30 adapted to fit within it. Multiple guide rods for guiding the upright plates 32 are fixedly mounted within each adjustment cavity 30. The guide rods allow the upright plates 32 to move stably within the adjustment cavity 30.

[0025] Each of the upright plates 32 has a guide post 321 fixedly installed at the top, and the guide post 321 is adapted to guide the horizontal plate 33. The guide post 321 can improve the stability of the horizontal plate 33 during movement.

[0026] The top of each vertical plate 32 has multiple downward-facing spring cavities, each containing an upward-facing spring 322, the other end of which is connected to the horizontal plate 33. The springs 322 allow the horizontal plate 33 to be pulled downwards, ensuring it is stably secured within the long or short limiting cavity 421.

[0027] Each rotating column 4 has a top member 42 fixedly installed on its top, and each top member 42 is adapted to be located at the bottom of the horizontal plate 33. Each top member 42 has a long limiting cavity 421 and a short limiting cavity 422, and both the long limiting cavity 421 and the short limiting cavity 422 are adapted to the horizontal plate 33.

[0028] In this embodiment, the waste gas treatment device body 1 is an activated carbon adsorption device, which consists of a housing, an activated carbon layer, and an inlet and outlet. Utilizing the porous structure of activated carbon, it removes pollutants from the gas through physical or chemical adsorption, and then discharges the purified gas. It is worth noting that the specific structure of the waste gas treatment device body 1 and its purification method are existing technologies and are not related to the technical problem of easily cleaning the filter assembly 22 that needs to be addressed in this technical solution; therefore, they will not be elaborated upon further.

[0029] Furthermore, when the user needs to clean the filter assembly 22, simply stop the device and then pull the horizontal plate 33 upward. At this time, the spring 322 is stretched, and the horizontal plate 33 is no longer stuck in the long limiting cavity 421.

[0030] At this point, the user can rotate the rotating columns 4 on both sides to rotate the locking piece 41 out of the locking cavity 23, thereby releasing the mutual locking between the locking piece 41 and the locking cavity 23. Then, the user can move the upright plate 32 and the horizontal plate 33 laterally to pull the brush plate 31 out of the cleaning plate 3. When the horizontal plate 33 moves above the short limiting cavity 422, the user only needs to release the horizontal plate 33. At this time, the horizontal plate 33 will automatically fall back to its original position by the elastic force of the spring 322, thereby automatically locking the horizontal plate 33 into the short limiting cavity 422.

[0031] Next, the user only needs to pull the rotating column 4 vertically back and forth, which will drive the cleaning plate 3 to move vertically back and forth. This will allow the dust on the filter assembly 22 to be brushed off by the brush plate 31 on the cleaning plate 3. Finally, the brushed dust will fall out from the bottom of the dust brushing chamber 21.

[0032] After cleaning the filter assembly 22, the user simply pulls the horizontal plate 33 upwards again to release the engagement between the horizontal plate 33 and the short limiting cavity 422. Then, the vertical plate 32 and the horizontal plate 33 are moved laterally to retract the brush plate 31 into the cleaning plate 3. Next, the rotating columns 4 on both sides are rotated so that the locking piece 41 rotates back into the locking cavity 23, at which point the long limiting cavity 421 and the horizontal plate 33 are aligned. Releasing the horizontal plate 33 at this point allows it to automatically engage within the long limiting cavity 421, thus locking the locking piece 41 in place.

[0033] Furthermore, a through hole is provided in the middle of the cleaning plate 3 corresponding to the air intake pipe, and sealing elements are provided on the outer wall of the cleaning plate 3 and the inner wall of the brushing chamber 21 to ensure the airtightness of the air intake pipe.

[0034] It is worth noting that the cleaning method in this embodiment is only a preliminary cleaning, which is convenient for cleaning the filter assembly 22 during short-term use. When a deep cleaning of the filter assembly 22 is required, the filter assembly 22 still needs to be removed for cleaning.

[0035] In this utility model, the exhaust gas can be treated by the exhaust gas treatment device body 1. The cleaning plate 3 can be fixed by the mutual locking between the clip 41 and the clip cavity 23. The filter screen assembly 22 can be cleaned by the brush plate 31. This method of cleaning the filter screen assembly 22 does not require disassembling the filter screen assembly 22, which makes it convenient for users to clean the filter screen assembly 22 when there is not too much dust on it, thus saving time.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
