Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment equipment, in particular to a waste gas treatment device which can automatically unfold a filter disc after being blocked. Background Art

[0002] Waste gas treatment is also known as waste gas purification. Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before external discharge to meet the standards for external discharge. The adsorption method in waste gas treatment is mainly suitable for low-concentration, high-throughput organic waste gas. Activated carbon, zeolite molecular sieves, activated alumina and resin adsorbents can be used for waste gas adsorption treatment to achieve emission targets.

[0003] However, most of the current exhaust gas treatment devices have the following problems:

[0004] 1. Most of the existing exhaust gas treatment devices need to filter the dust and impurities in the exhaust gas through filtering components such as filters. However, the filters are mostly fixed or stuck in the equipment during filtering. If the filters need to be cleaned, it is more troublesome. When the filters are taken out, they cannot be replaced immediately, which easily leads to a large amount of unfiltered exhaust gas being discharged, affecting the treatment stability and making it inconvenient to use the filters conveniently.

[0005] 2. The existing exhaust gas treatment device is prone to clogging after long-term use. If it is not handled in time, it is easy to affect the filtering efficiency of the filter. It is more troublesome to clean the filter and it is inconvenient to clean the filter conveniently and collect the dust centrally.

[0006] Therefore, we have made improvements to this problem and proposed an exhaust gas treatment device that automatically unfolds the filter disc when it is blocked. Utility Model Content

[0007] The purpose of the utility model is to solve the current problems of inconvenience in conveniently unfolding and using the filter, inconvenience in conveniently cleaning the filter, and inconvenience in centrally collecting and processing dust.

[0008] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0033] Embodiment 2:

[0034] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0035] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the first hydraulic cylinder 5 is symmetrically distributed on the left and right sides of the protective shell 1, and the first hydraulic cylinder 5 corresponds to the filter plate 7 one by one through the connecting plate 6, which can ensure that the filter plates 7 on both sides can improve the filtering efficiency and the stability of replacement use.

[0036] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the baffle 8 is fitted with the inner side face of the connecting frame 3, and the activated carbon plates 9 are evenly distributed in the treatment pipe 2, which can ensure that multiple activated carbon plates 9 can effectively treat the exhaust gas.

[0037] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the collecting boxes 10 are symmetrically distributed on the upper and lower sides of the protective shell 1, and the collecting boxes 10 correspond one-to-one with the conveying telescopic tubes 12 through the pump body 11, which can ensure that multiple conveying telescopic tubes 12 cooperate with the air collecting box 13 to improve the cleaning efficiency.

[0038] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the air intake pipe 14 and the brush 15 are alternately distributed on the air collecting box 13, and the output shaft of the motor 18 is fixedly connected to the center part of one side of the gear 19, which can ensure that the motor 18 can smoothly drive the gear 19 to operate when it is running.

[0040] Specifically, when the exhaust gas treatment device that automatically expands the filter disc after being blocked is used: Figure 1-4 When the exhaust gas is treated, the exhaust gas is transported through the treatment pipe 2 on the protective shell 1. During the transportation, the exhaust gas can be filtered through the filter plate 7 in the connecting frame 3. During the filtering, the sealing gasket 4 on the connecting frame 3 can prevent the exhaust gas from leaking. After the filtering is completed, it is filtered multiple times through the activated carbon plate 9 to filter and adsorb the harmful substances in the exhaust gas. If the filter plate 7 is blocked and needs to be expanded and replaced, the first hydraulic cylinder 5 on one side can be opened. The first hydraulic cylinder 5 can pull out the blocked filter plate 7 through the connecting plate 6. While pulling the filter plate 7, the baffle 8 can be driven to move at the same time.

[0041] When cleaning the filter plate 7, the second hydraulic cylinder 16 can be opened to push the mounting plate 17. When the mounting plate 17 moves, it can smoothly drive the air collecting box 13 on the conveying telescopic tube 12 to move. When the air collecting box 13 moves, the brush 15 can be pushed to fit on the filter plate 7, and then the motor 18 on the mounting plate 17 is turned on. The motor 18 smoothly drives the gear 19 to rotate. When the gear 19 rotates, it can smoothly push the air collecting box 13 to rotate through the gear block 20. When the air collecting box 13 rotates, the impurities on the filter plate 7 can be smoothly cleaned through the brush 15 on the air collecting box 13. While cleaning, the pump body 11 can be opened. The pump body 11 absorbs and collects the cleaned impurities through the multiple suction pipes 14 on the air collecting box 13, and then transports them to the collecting box 10 through the conveying telescopic tube 12, so as to centrally collect and process the cleaned dust and impurities, thereby improving the cleaning efficiency of the filter plate 7.
