Description

Technical Field

[0001] This utility model relates to the field of exhaust gas filtration, and more specifically, to an exhaust gas filtration device. Background Technology

[0002] In today's rapidly developing industrialization process, various industrial production activities, such as chemical, metallurgical, and machinery manufacturing, as well as transportation and catering services, generate a large amount of waste gas. This waste gas contains pollutants such as dust, particulate matter, sulfides, nitrogen oxides, and volatile organic compounds (VOCs). If released directly into the atmosphere without effective treatment, it will cause serious environmental problems, such as acid rain, negatively impacting ecological balance, human health, and the global climate. With increasing environmental awareness and growing emphasis on environmental protection in various countries, increasingly stringent waste gas emission standards have been introduced, requiring enterprises to adopt effective waste gas treatment technologies to ensure compliance with emission standards. This has prompted enterprises to actively seek more efficient and reliable waste gas filtration equipment.

[0003] Chinese utility model patent CN221412561U discloses an organic waste gas filtration device. During use, this device can move up and down on one side of the filter screen to scrape and clean it, removing accumulated debris. Simultaneously, the cleaning mechanism is linked with a blocking plate; as the filter screen is scraped and cleaned, the blocking plate moves up and down to open and close the open area, facilitating the active discharge of cleaned impurities. This saves time and effort, eliminates the need for manual maintenance, and reduces subsequent manual cleaning workload, keeping the filter screen in good filtration condition. However, when cleaning the filter screen, harmful waste gas entering the filter box can escape into the outside through the open area. This not only pollutes the surrounding environment, affecting air quality and damaging the ecological balance, but also poses a serious threat to the health of operators, leading to poisoning, respiratory diseases, and other health problems.

[0004] Therefore, it is necessary to redesign an exhaust gas filtration device to address the aforementioned issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an exhaust gas filtration device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waste gas filtration device includes a filter box. Two sealing devices are symmetrically arranged at the bottom of the filter box. Two sliding grooves are symmetrically opened on the inner walls of both sides of the filter box. A slider is inserted into each sliding groove. A filter plate is fixedly installed between two corresponding sliders. Two through slots are symmetrically opened on the inner bottom wall of the filter box, and the output ends of the two sealing devices are respectively connected to the two through slots. A cover plate is provided on the upper surface of the filter box. Two receiving slots are symmetrically opened at the bottom of the cover plate. A motor is fixedly installed on the upper surface of the cover plate. A screw is fixedly connected to the output shaft of the motor. A fixing plate is threaded onto the screw. Two sets of fixing rods are symmetrically fixedly installed at the bottom of the fixing plate. The output shafts of both sets of fixing rods pass through the upper surface of the cover plate and extend into the two receiving slots, where cleaning devices are installed.

[0008] like Figure 1-5 As shown, the specific implementation method is as follows: by setting up cleaning devices, sealing devices and other devices, during the cleaning process of the filter plate, the sealing plate can promptly replace the sealing block to seal the through groove, prevent the exhaust gas from escaping, and avoid harm to the environment and operators. After cleaning, the torsion spring drives the sealing block to re-lock, ensuring that the bottom of the filter box is always in a good sealing state, thus improving the safety and environmental protection of the entire device.

[0009] In a preferred embodiment, each of the sealing devices includes two mounting blocks, which are symmetrically and fixedly mounted at the bottom of the filter box. A fixed shaft is rotatably mounted between the two mounting blocks. Two connecting blocks are symmetrically and fixedly mounted on the outer wall of the fixed shaft. Torsion springs are fixedly connected between the two connecting blocks and the corresponding mounting blocks. Two locking blocks are symmetrically and fixedly mounted on the outer wall of the fixed shaft. One end of the two locking blocks is fixedly connected to a fixed block. A sealing block is fixedly mounted on the upper surface of the fixed block and engages in a corresponding through groove.

[0010] In a preferred embodiment, each of the cleaning devices includes a mounting plate, which is fixedly mounted on the bottom end of a set of fixed rods in corresponding positions.

[0011] In a preferred embodiment, the positions of the two sealing plates correspond to the positions of the two through slots, respectively.

[0012] In a preferred embodiment, each of the cleaning plates is fixedly mounted with a guide rod on the side away from the brush, and the two guide rods slide through one side of the mounting plate corresponding to the position and extend outward.

[0013] In a preferred embodiment, air vents are connected to both sides of the filter box.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a cleaning device and a sealing device. During the cleaning process, the sealing plate can promptly replace the sealing block to seal the passageway, preventing exhaust gas from escaping and avoiding harm to the environment and operators.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-5A waste gas filtration device includes a filter box 1. Two sealing devices are symmetrically arranged at the bottom of the filter box 1. Two sliding grooves 12 are symmetrically opened on the inner walls of both sides of the filter box 1. A slider 9 is inserted into each sliding groove 12. A filter plate 10 is fixedly installed between two corresponding sliders 9. Two through grooves 11 are symmetrically opened on the inner bottom wall of the filter box 1. The output ends of the two sealing devices are respectively connected to the two through grooves 11. A cover plate 2 is provided on the upper end face of the filter box 1. Two receiving grooves 13 are symmetrically opened at the bottom end of the cover plate 2. A motor 3 is fixedly installed on the upper end face of the cover plate 2. A screw 4 is fixedly connected to the output shaft of the motor 3. A fixing plate 5 is threadedly connected to the screw 4. Two sets of fixing rods 6 are symmetrically fixedly installed at the bottom end of the fixing plate 5. The output shafts of the two sets of fixing rods 6 pass through the upper end face of the cover plate 2 and extend into the two receiving grooves 13 respectively to install cleaning devices.

[0024] Each sealing device includes two mounting blocks 7, which are symmetrically and fixedly installed at the bottom of the filter box 1. A fixed shaft 20 is rotatably mounted between the two mounting blocks 7. Two connecting blocks 22 are symmetrically and fixedly installed on the outer wall of the fixed shaft 20. Torsion springs 21 are fixedly connected between the two connecting blocks 22 and the corresponding mounting blocks 7. Two locking blocks 23 are symmetrically and fixedly installed on the outer wall of the fixed shaft 20. A fixed block 8 is fixedly connected to one end of the two locking blocks 23. A sealing block 24 is fixedly installed on the upper end face of the fixed block 8, and the sealing block 24 is engaged in the corresponding through groove 11. When it is not necessary to clean the inside of the filter box 1, the sealing block 24 of the sealing device is engaged in the through groove 11 to prevent exhaust gas from leaking from the bottom of the filter box 1, thus achieving a sealing function.

[0025] Each cleaning device includes a mounting plate 14, which is fixedly installed at the bottom of a set of fixed rods 6 in corresponding positions. Two springs 16 are symmetrically fixedly connected to one side of the mounting plate 14. A cleaning plate 17 is fixedly installed at one end of the two springs 16. A brush 19 is provided on one side of the cleaning plate 17. A sealing plate 15 is fixedly installed at the bottom of the mounting plate 14. Two top rods 25 are symmetrically fixedly installed at the bottom of the sealing plate 15. The elasticity of the springs 16 allows the brush 19 to fit tightly against the filter plate 10.

[0026] The positions of the two sealing plates 15 correspond to the positions of the two through slots 11, respectively.

[0027] Each cleaning plate 17 has a guide rod 18 fixedly installed on the side away from the brush 19, and the two guide rods 18 slide through one side of the mounting plate 14 corresponding to the position and extend outward.

[0028] The filter box 1 has ventilation pipes connected to both sides, and exhaust gas can enter the filter box 1 through the ventilation pipes.

[0029] When this utility model is in use, the exhaust gas enters the filter box 1 through the ventilation pipes connecting both sides of the filter box 1. When the exhaust gas passes through the filter plate 10, the impurities in it are intercepted and filtered by the filter plate 10, thereby purifying the exhaust gas. The purified gas is discharged from the ventilation pipe on the other side.

[0030] When the filter plate 10 needs to be cleaned, the motor 3 is started. The output shaft of the motor 3 rotates, which drives the screw 4 to rotate. The fixed plate 5, which is threaded on the screw 4, moves up and down along the screw 4. The movement of the fixed plate 5 will synchronously drive the two sets of fixed rods 6 to move. At this time, the movement of the fixed rods 6 will drive the cleaning device to move down synchronously. When the cleaning device descends, the brush 19 contacts the filter plate 10. As the fixed plate 5 continues to descend, the spring 16 is compressed, so that the brush 19 can stick tightly to the filter plate 10. With the up and down reciprocating movement of the fixed plate 5, the brush 19 cleans the filter plate 10 and brushes off the impurities intercepted on the filter plate 10. Then the impurities on the filter plate 10 will fall onto the sealing block 24.

[0031] Since two top rods 25 are symmetrically fixedly installed at the bottom of the sealing plate 15, and the positions of the two sealing plates 15 correspond to the positions of the two through slots 11 respectively, during the descent of the cleaning device, the sealing plate 15 will first contact the sealing block 24. At this time, the sealing plate 15 will replace the sealing block 24 to seal the through slot 11, preventing exhaust gas from drifting to the outside through the through slot 11. Then, the top rod 25 pushes the sealing block 24 to rotate around the fixed shaft 20, the torsion spring 21 deforms, and the sealing block 24 disengages from the through slot 11, so that the through slot 11 opens. Impurities brushed off the filter plate 10 by the brush 19 are discharged from the filter box 1 through the through slot 11. After cleaning, the motor 3 reverses, the fixed plate 5 rises, the sealing plate 15 leaves the sealing block 24, the torsion spring 21 returns to its deformation, and drives the sealing block 24 to re-engage in the through slot 11, completing the seal. At the same time, the cleaning device returns to the storage slot 13.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
