Description

Technical Field

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

[0002] The waste gases emitted during industrial production are highly complex, containing flammable gases, acidic gases (such as sulfuric acid mist), alkaline gases (such as hydrogen fluoride and nitric acid mist), and particulate matter, among other things. These substances can pollute the environment and harm human health. Therefore, they need to be purified.

[0003] Waste gas treatment equipment refers to a device that uses physical, chemical or biological methods to remove pollutants from waste gas, and is a technical measure to make harmful gases meet emission standards.

[0004] A combined waste gas treatment device with prior art disclosure number CN217092601U includes a waste gas treatment box, one end of which is connected to a cooling chamber. A cold air fan is connected to the bottom of the cooling chamber, and one end of the cooling chamber is connected to an air inlet pipe. A fan is installed at the end of the waste gas treatment box away from the cooling chamber. An air outlet pipe is fixedly connected to the air outlet of the fan. A filter assembly is installed inside the waste gas treatment box and at the end closest to the cooling chamber.

[0005] The waste gas treatment device requires the waste gas treatment box to be opened before the primary filter and activated carbon adsorption plate can be replaced. During this period, the entire waste gas treatment device is shut down and cannot be used, which will affect the continuity of waste gas treatment and reduce the efficiency of waste gas treatment. Therefore, an improvement is proposed. Utility Model Content

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a combined waste gas treatment device, including a waste gas treatment box, a shell fixedly connected to the top of the waste gas treatment box, a synchronous drive assembly installed inside the shell, and lead screws fixedly connected to the four output ends of the synchronous drive assembly, and the lead screws are rotatably connected to the waste gas treatment box.

[0008] The outer surfaces of the four lead screws are threaded with movable frames, and the movable frames extend through the top of the exhaust gas treatment box into the interior. The bottom of each of the four movable frames is symmetrically fixed with two cover plates.

[0009] The exhaust gas treatment box is internally fixedly connected with three first baffles and one second baffle. Two slots are symmetrically opened on one side of the outer surface of each of the three first baffles and the second baffle.

[0012] Furthermore, two support blocks are symmetrically rotated and fitted onto the outer surface of the rotating shaft, and the support blocks are fixedly connected to the housing. The support blocks provide support for the rotating shaft, which is beneficial for the installation of the rotating shaft.

[0013] Furthermore, all four movable frames slide in a sealed manner with the exhaust gas treatment box, and the exhaust gas treatment box has a limiting effect on the movable frames, which can ensure the stability of the movement of the movable frames.

[0014] Furthermore, each of the eight cover plates has a sealing strip fixedly connected to its outer surface, and the sealing strip is in sealing contact with the inner wall of the exhaust gas treatment box, and the sealing strip is in sealing contact with the outer wall of the adjacent first baffle and second baffle.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 3As shown, a combined waste gas treatment device is disclosed, including a waste gas treatment box 1. A housing 4 is fixedly connected to the top of the waste gas treatment box 1. A synchronous drive assembly is installed inside the housing 4. Each of the four output ends of the synchronous drive assembly is fixedly connected to a lead screw 17, and the lead screw 17 is rotatably connected to the waste gas treatment box 1. The synchronous drive assembly includes a motor 18, which is fixedly installed on one side of the inner surface of the housing 4. A rotating shaft 16 is fixedly connected to the drive end of the motor 18. Four first bevel gears 8 are fixedly sleeved on the outer surface of the rotating shaft 16. A second bevel gear 9 is meshed on one side of the outer surface of each of the four first bevel gears 8, and the second bevel gear 9 is fixedly connected to the adjacent lead screw 17. Two support blocks 14 are symmetrically rotatably sleeved on the outer surface of the rotating shaft 16, and the support blocks 14 are fixedly connected to the housing 4. The support blocks 14 provide support for the rotating shaft 16, which is beneficial for the installation of the rotating shaft 16.

[0027] The outer surfaces of the four lead screws 17 are threaded with movable frames 10. The spiral direction of the lead screws 17 is selected according to actual needs, and it is necessary to meet the requirement that two adjacent movable frames 10 are one above the other. The movable frames 10 extend through the top of the exhaust gas treatment box 1 and into the interior. The four movable frames 10 are sealed and slide with the exhaust gas treatment box 1. Two sealing sleeves are symmetrically slidably fitted on the outer surface of the movable frames 10, and the sealing sleeves are fixedly connected to the exhaust gas treatment box 1. The bottom of the four movable frames 10 is symmetrically fixedly connected with two cover plates 11. The outer surfaces of the eight cover plates 11 are fixedly connected with sealing strips 21, and the sealing strips 21 are sealed and abut against the inner wall of the exhaust gas treatment box 1. The sealing strips 21 are also sealed and abut against the outer walls of the adjacent first baffle 15 and second baffle 20.

[0028] The exhaust gas treatment box 1 is internally fixedly connected with three first baffles 15 and one second baffle 20. Two slots 13 are symmetrically opened on one side of the outer surface of the three first baffles 15 and the second baffle 20. The two slots 13 on the first baffle 15 are sealed and inserted with a primary filter screen 12. The two slots 13 on the second baffle 20 are sealed and inserted with an activated carbon adsorption plate 19. Sealing gaskets should be provided on the inner walls on both sides of the slots 13 to ensure the sealing of the primary filter screen 12 or the activated carbon adsorption plate 19 after insertion.

[0029] Multiple doors 3 are sealed and hinged on one side of the outer surface of the exhaust gas treatment box 1. The doors 3 are sealed and abut against the adjacent first baffle 15, second baffle 20, primary filter 12 and activated carbon adsorption plate 19. When the doors 3 are opened, the openings on the exhaust gas treatment box 1 are inside the space formed by the two adjacent cover plates 11. At the same time, rubber gaskets are fixedly installed on the inner surface of the doors 3 to ensure the sealing with the adjacent first baffle 15, second baffle 20, primary filter 12 and activated carbon adsorption plate 19.

[0030] An air inlet pipe 2 and a spray box 5 are fixedly connected to both ends of the exhaust gas treatment box 1, respectively. A fan 6 is fixedly connected to one side of the outer surface of the spray box 5, and an air outlet pipe 7 is fixedly connected to the air outlet end of the fan 6. Here, the spray box 5 adopts the spray area setting of a combined exhaust gas treatment device with the prior art publication number CN217092601U, the function of which is to remove odors.

[0031] Working principle: When it is necessary to replace the pre-filter 12 and activated carbon adsorption plate 19 that are in use, the motor 18 starts and drives the rotating shaft 16 to rotate. The rotating shaft 16 drives multiple first bevel gears 8 to rotate, and the multiple first bevel gears 8 drive the second bevel gears 9 connected to them to rotate. The second bevel gears 9 drive the lead screw 17 connected to them to rotate, so that the two adjacent movable frames 10 rise and fall. The movable frames 10 drive the two cover plates 11 connected to them to move until the pre-filter 12 and activated carbon adsorption plate 19 that are in use are between the two adjacent cover plates 11. The cover plate 11, in cooperation with the sealing strip 21, can form a sealed space with the inner wall of the exhaust gas treatment box 1, the first baffle 15 or the second baffle 20. Then, the corresponding box door 3 is opened without affecting the use of the exhaust gas treatment box 1. Then, the operation of replacing the pre-filter 12 and activated carbon adsorption plate 19 is carried out. After the replacement is completed, the box door 3 is closed.

[0032] It should be noted that the specific models and specifications of the fan 6, motor 18, activated carbon adsorption plate 19, and primary filter 12 are determined based on the actual usage.
