Molecular sieve waste gas treatment device

Abstract

The utility model relates to a molecular sieve waste gas treatment device, and aims to solve the problems that although the molecular sieve desorption waste gas treatment device can switch and adjust different adsorption chambers to perform waste gas adsorption treatment, when one adsorption chamber is used, other adsorption chambers are exposed in the air, and the waste gas cannot be adsorbed. The utility model relates to a multi-stage adsorption device which solves the technical problems that the difficulty of separating a mixture is increased and the follow-up treatment effect is reduced due to the fact that molecular sieve particles in other adsorption chambers can absorb moisture in the air and the pore diameter of the molecular sieve particles is increased when the molecular sieve particles in the other adsorption chambers can absorb the moisture in the air. Therefore, replacement and adjustment of filter plates in the first limiting frame and the second limiting frame on the front side and molecular sieve plates in the first limiting frame and the second limiting frame on the rear side are achieved, and meanwhile protection frames located on the two sides of the conveying cylinder frame can effectively shield, seal and protect the filter plates and the molecular sieve plates in the first limiting frame or the second limiting frame. Dust accumulation on the surface of the filter plate and moisture absorption of the molecular sieve plate are avoided.

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0027] A molecular sieve waste gas treatment device, see Figures 1 to 6 , comprising a base 1, a transmission drum frame 2 is provided on the surface of the base 1, an adsorption frame 3 is connected to the rear of the transmission drum frame 2, a negative pressure fan is provided inside the adsorption frame 3, a group of adjustment mechanisms 4 are provided on the side of the transmission drum frame 2, a filter plate 5 and a molecular sieve plate 6 are respectively engaged inside the group of adjustment mechanisms 4, and a convenient mechanism 7 is provided on the surface of the adjustment mechanism 4;

[0028] The adjusting mechanism 4 includes a protective frame 401, which is fixedly arranged on both sides of the transmission drum frame 2. The side wall of the base 1 is connected to a multi-stage hydraulic cylinder 402, and the movable end of the multi-stage hydraulic cylinder 402 is connected to a first limiting frame 403, and the first limiting frame 403 is connected to a second limiting frame 404 on the side away from the multi-stage hydraulic cylinder 402, wherein a card slot is opened on the surface of the transmission drum frame 2, and the first limiting frame 403 and the second limiting frame 404 are respectively matched and engaged with the card slot, and the first limiting frame 403 and the second limiting frame 404 are fixedly connected. Further, the first limiting frame 403 and the second limiting frame 404 are respectively matched and engaged with the protective frame 401, and a group of protective frames 401 are connected. Further, the front first limiting frame 403 and the second limiting frame 404 are internally engaged with filter plates 5 of different diameters, and the rear first limiting frame 403 and the second limiting frame 404 are internally engaged with molecular sieve plates 6 of different diameters. The utility model uses a multi-stage hydraulic cylinder 402 to effectively drive the first limiting frame 403 and the second limiting frame 404 to translate, thereby realizing the replacement and adjustment of the filter plate 5 inside the first limiting frame 403 and the second limiting frame 404 on the front side and the molecular sieve plate 6 inside the first limiting frame 403 and the second limiting frame 404 on the rear side, thereby improving the practicality of the device. At the same time, the protective frame 401 located on both sides of the transmission cylinder frame 2 can effectively block and seal the filter plate 5 and the molecular sieve plate 6 in the first limiting frame 403 or the second limiting frame 404 to avoid dust accumulation on the surface of the filter plate 5 and moisture absorption by the molecular sieve plate 6.

[0029] It is worth noting that the convenient mechanism 7 includes a fixed frame 701, which is fixed on the surface of the first limit frame 403 and the second limit frame 404. A handle 702 runs through the inside of the fixed frame 701. A limit ring plate 703 is fixedly sleeved on the surface of the handle 702. A spring 704 is connected to the side of the limit ring plate 703. The end of the handle 702 is engaged in the filter plate 5, and the handle 702 forms an elastic structure with the fixed frame 701 through the limit ring plate 703 and the spring 704. When the filter plate 5 or the molecular sieve plate 6 needs to be inspected and replaced in the utility model, the handle 702 is pulled outward, which effectively separates the end of the handle 702 from the inside of the filter plate 5 or the molecular sieve plate 6. At this time, the filter plate 5 or the molecular sieve plate 6 is not constrained and can be directly pulled out of the limiting frame. After the inspection and replacement is completed, the handle 702 is pulled outward to re-insert the filter plate 5 or the molecular sieve plate 6 into the limiting frame, and then the handle 702 is released. Under the influence of the rebound force of the spring 704, the end of the handle 702 is re-inserted into the filter plate 5 or the molecular sieve plate 6, and the filter plate 5 or the molecular sieve plate 6 is re-limited to improve the placement stability.

[0030] Working principle: The multi-stage hydraulic cylinder 402 drives the first limiting frame 403 and the second limiting frame 404 to move horizontally, so as to facilitate the selection of the filter plate 5 and the molecular sieve plate 6 as needed. After the selection is completed, the limiting frames where the required filter plate 5 and the molecular sieve plate 6 are located are snapped into the inner side of the transmission drum frame 2. At the same time, the protective frames 401 located on both sides of the transmission drum frame 2 can block and seal the filter plates 5 and the molecular sieve plates 6 in the unselected limiting frames to prevent dust accumulation on the surface of the unselected filter plates 5 and moisture absorption by the unselected molecular sieve plates 6. Then, the negative pressure fan inside the adsorption frame 3 is started to start the exhaust gas treatment. The exhaust gas enters the transmission drum frame 2 from the front end inlet. The filter plate 5 first The waste gas is initially filtered, and then the molecular sieve plate 6 further adsorbs and treats the waste gas, and the treated clean gas is discharged through the adsorption frame 3. When the filter plate 5 or the molecular sieve plate 6 needs to be inspected and replaced later, the handle 702 is pulled outward to make the end of the handle 702 separate from the filter plate 5 or the molecular sieve plate 6. At this time, the filter plate 5 or the molecular sieve plate 6 is not constrained and can be directly pulled out of the limit frame. After the inspection and replacement is completed, the handle 702 is pulled outward to re-insert the filter plate 5 or the molecular sieve plate 6 into the limit frame, and then the handle 702 is released. Under the influence of the rebound force of the spring 704, the end of the handle 702 is re-inserted into the filter plate 5 or the molecular sieve plate 6, and the filter plate 5 or the molecular sieve plate 6 is re-limited.
