Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a waste gas treatment box. Background Technology

[0002] In industrial production processes, the emission of large amounts of waste gas not only causes serious environmental pollution but also poses a threat to the health of workers. Waste gas treatment boxes, as a highly efficient waste gas treatment device, have become an ideal choice for treating organic waste gas due to their strong adsorption capacity, convenient maintenance, and wide applicability. Some existing waste gas treatment boxes typically install waste gas treatment devices inside the box, which treat the waste gas during its flow. However, during use, some waste gas treatment boxes make it inconvenient to clean the waste gas treatment devices. After a period of use, the devices must be stopped for cleaning or replaced, which reduces the efficiency of the waste gas treatment box.

[0003] Therefore, an exhaust gas treatment box is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a waste gas treatment box.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An exhaust gas treatment box includes a box body having a left end and a right end. The left end is provided with an air inlet, and the right end is provided with an air outlet. The air outlet and the air inlet are connected through an air duct. At least one set of exhaust gas filtration devices is provided in the air duct. The exhaust gas filtration device includes a rotating shaft extending into the air duct. The rotating shaft is rotatably connected to the box body. A plurality of filter plates are arranged in a circumferential array on the rotating shaft, and a cleaning device is provided on any of the filter plates.

[0007] Furthermore, in this utility model, two arc-shaped receiving grooves are symmetrically arranged inside the air passage, the centers of the two arc-shaped receiving grooves are collinear, and the edge of any of the filter plates can abut against the bottom wall of any of the arc-shaped receiving grooves.

[0008] Furthermore, in this utility model, the filter plate has two filter surfaces; the cleaning device includes a frame that is slidably connected to the filter plate, and two sets of brushes are symmetrically arranged on the frame, with the brushing ends of the two sets of brushes respectively abutting against the two filter surfaces of the filter plate.

[0009] Furthermore, in this utility model, a first magnetic block is provided at one end of the frame, and a second magnetic block with opposite magnetism to the first magnetic block is provided at both ends of one side of the filter plate.

[0010] Furthermore, in this utility model, an exhaust fan is provided inside the aforementioned air outlet.

[0011] The beneficial effects of this utility model are:

[0012] This utility model provides an exhaust gas treatment box. By installing at least one set of exhaust gas filtration devices inside the box, the exhaust gas flowing from the air duct to the air outlet can be filtered. The cleaning device installed on each filter plate can automatically clean the dust on both filter surfaces of the filter plate during the rotation of the shaft, thereby improving the normal service life of the filter plate.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution:

[0020] An exhaust gas treatment box includes a box body 101, which has a left end and a right end. An air inlet 201 is provided at the left end, and an air outlet 301 is provided at the right end. The air outlet 301 and the air inlet 201 are connected through an air duct 401. An exhaust fan 901 is also installed inside the air outlet 301, which facilitates the rapid flow of exhaust gas from the air duct 401 to the air outlet 301. At least one set of exhaust gas filtration devices is provided inside the air duct 401. Each exhaust gas filtration device includes a rotating shaft 501 extending into the air duct 401. The rotating shaft 501 is rotatably connected to the box body 101, and one end of the rotating shaft 501 is drivenly connected to a motor (not shown in the figure). Figure 2 As shown, a number of filter plates 502 are installed in a circular array on the rotating shaft 501. A cleaning device is installed on any filter plate 502. This cleaning device is used to clean the dust on the filter plate 502 during the rotation of the rotating shaft 501, so as to improve the normal service life of the filter plate 502.

[0021] In this embodiment, filter plate 502 is made of activated carbon. Activated carbon is a commonly used waste gas treatment material with high adsorption efficiency and large adsorption capacity, suitable for treating various organic compounds and gaseous pollutants. Activated carbon materials are widely used in many industries such as electronics, chemicals, and coating, and can effectively remove harmful substances from waste gas. In other embodiments of this example, filter plate 502 can also be made of materials such as membrane polyester filter media and silicone oil anti-condensation filter media. Among them, membrane polyester filter media is mainly used in bag-type waste gas treatment equipment, and has excellent chemical corrosion resistance and long service life. This filter media is suitable for filtration in many industrial fields such as welding fumes and shot peening casting, and can effectively prevent adhesion and facilitate dust removal.

[0022] Reference Figure 2 To facilitate the accommodation of the filter plates 502 of the exhaust gas filtration device, two symmetrical arc-shaped receiving grooves 601 are designed inside the air passage 401 in this embodiment. The centers of the two arc-shaped receiving grooves 601 are collinear, and the edge of any filter plate 502 can abut against the bottom wall of any arc-shaped receiving groove 601. In this embodiment, six filter plates 502 are installed on the rotating shaft 501. In this way, no matter how large the rotation angle of the rotating shaft 501 is, two symmetrical filter plates 502 that abut against the two arc-shaped receiving grooves 601 respectively, along with the rotating shaft 501, can block the air passage 401. This ensures that the exhaust gas flowing into the air passage 401 through the air inlet 201 can only flow to the air outlet 301 through the filter plates 502, thereby being filtered.

[0023] Reference Figure 2 and Figure 3In this embodiment, the filter plate 502 has two filter surfaces. Specifically, the cleaning device includes a frame 701 slidably connected to the filter plate 502. Two sets of brushes 702 are symmetrically arranged on the frame 701, and the brushing ends of the two sets of brushes 702 respectively abut against the two filter surfaces of the filter plate 502. Guide rails are installed on both ends of the filter plate 502, and the frame 701 is slidably connected to the guide rails via ball bearings. (Refer to...) Figure 2 When the rotating shaft 501 rotates under the control of the motor, the frame 701 on part of the filter plate 502 can slide downward under the action of gravity, thus achieving the purpose of automatically cleaning the filter surface of the filter plate 502.

[0024] Reference Figure 4 To facilitate the rapid sliding of the frame 701 on the filter plate 502 under the influence of gravity, a first magnetic block 801 is installed at one end of the frame 701, and a second magnetic block 802 with opposite magnetism to the first magnetic block 801 is installed at both ends of one side of the filter plate 502. Thus, when the first magnetic block 801 approaches any of the second magnetic blocks 802, the repulsive force between them prevents the first magnetic block 801 from making complete contact with the second magnetic block 802. Furthermore, when the first magnetic block 801 tends to move towards another second magnetic block 802 under the influence of gravity, the repulsive force between them makes it easier for the first magnetic block 801 to move away from the current second magnetic block 802.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
