Description

Technical Field

[0001] This utility model relates to the field of chemical production, and in particular to a sealing device for effectively collecting exhaust gas from a full-flow channel. Background Technology

[0002] In the chemical production field, especially in the ammonium sulfate production process, the full-flow tank is one of the key pieces of equipment. Traditional ammonium sulfate full-flow tanks are mostly designed with an open top, mainly for the purpose of facilitating daily inspection and operation. Operators can directly observe the situation inside the tank and easily perform some simple operations. Due to its open structure, the existing full-flow tanks cannot meet the requirements for effective sealing and collection of exhaust gas, resulting in the unorganized emission of a large amount of VOCs, causing serious pollution to the surrounding environment. Therefore, a sealing device is needed to ensure its sealing requirements. To this end, a visual and effective sealing device for collecting exhaust gas from the full-flow tank is proposed to solve the above problems. Utility Model Content

[0024] 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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a sealing device for effectively collecting exhaust gas from a full-flow tank. The device includes a full-flow tank 1, with a detachable fixed cover 2 mounted on the top. The fixed cover 2 is made of two modules, separate from the movable cover 5, and can be assembled for use. The inner wall of the fixed cover 2 is permeated and equipped with a feed pipe 3, allowing raw materials or intermediate products required for ammonium sulfate production to be added and fed into the full-flow tank 1 through the feed inlet, enabling the reaction or processing to proceed smoothly within the full-flow tank 1. The outer wall of the full-flow tank 1 is equipped with a discharge pipe 4, allowing the reacted or processed materials to be discharged for subsequent processing. In the subsequent processing steps, a movable cover plate 5 is hinged to the side wall of the fixed cover plate 2 via a hinge. The hinge is existing technology. After the movable cover plate 5 and the fixed cover plate 2 are assembled, they are connected by the hinge. An inspection tube 6 is fixedly connected to the top of the fixed cover plate 2. The operator can observe the processing inside the full flow trough 1 through the inspection tube 6. Rubber pads 11 are respectively provided at the bottom of the fixed cover plate 2 and the movable cover plate 5. The rubber pads 11 can contact the top of the full flow trough 1, which can meet the sealing requirements between the full flow trough 1 and the fixed cover plate 2 and the movable cover plate 5, and prevent exhaust gas from being discharged from between the fixed cover plate 2 and the movable cover plate 5. The outer wall of the movable cover plate 5 is provided with an anti-pinch component.

[0026] The anti-pinch assembly includes a fixed tube 7 and a connecting tube 10, which mainly connect and support the entire piston tube 9 and the moving tube 8. The fixed tube 7 is fixedly connected to the outer wall of the movable cover plate 5. The moving tube 8 is hinged to the outer wall of the fixed tube 7. The piston tube 9 is piston-connected to the outer wall of the moving tube 8. The piston tube 9 has a round hole that allows air to enter and exit the piston tube 9 through the round hole. The connecting tube 10 is hinged to the bottom end of the piston tube 9.

[0027] Reference Figures 1-3 The connecting pipe 10 is fixedly connected to the outer wall of the full flow channel 1.

[0028] Reference Figure 4 The bottom end of the rubber pad 11 is in contact with the top end of the full flow groove 1.

[0029] Reference Figures 1-3The top of the movable cover plate 5 is provided with a handle, which can be used to flip the movable cover plate 5 to meet the needs of subsequent maintenance or other work. There are two sets of fixed cover plates 2, which are fixedly connected by fastening bolts. The fixed cover plates 2 have mounting feet, through which bolts can be passed to connect the two sets of fixed cover plates 2 together. The outer wall of the piston tube 9 is provided with a round hole.

[0030] Working principle: When processing is required, the raw material is simply fed into the full flow tank 1 through the feed pipe 3. During the processing, the fixed cover plate 2 and the movable cover plate 5 at the top of the full flow tank 1 are kept in close contact through the rubber gasket 11 to ensure good sealing and prevent exhaust gas from leaking from the gaps in the cover plate. The staff can observe the processing situation inside the full flow tank 1 at any time through the inspection pipe 6 at the top of the fixed cover plate 2 so as to keep abreast of the production progress and discover any possible problems.

[0031] When maintenance or other operations are required, the operator flips the movable cover 5 using the handle at the top. This causes the fixed tube 7 and the moving tube 8 to move. The movement of the fixed tube 7 causes the moving tube 8, which is hinged to it, to undergo relative displacement within the piston tube 9. The moving tube 8 moves along the inner wall of the piston tube 9, drawing outside air into it. Simultaneously, during the flipping process, the moving tube 8 and piston tube 9 deflect along the outer walls of the fixed tube 7 and connecting tube 10. When closing the movable cover 5, simply flip it counterclockwise to reset it. This flipping action causes the moving tube 8 to compress the air within the piston tube 9, allowing the air to escape through the round hole. Due to the pressure change, a resistance is generated that prevents the moving tube 8 from rapidly compressing the air. This resistance effectively buffers the closing speed of the movable cover 5, preventing excessive impact from rapid closure and further ensuring safety during the closing process. This avoids accidental injury to the operator, thus enabling the entire anti-pinch assembly to operate flexibly and effectively preventing injury to the operator during the opening and closing of the movable cover 5.

[0032] After the operation is completed, ensure the sealing of the full flow tank 1, maintain the effective collection of exhaust gas during the production process, and ensure that the entire production process continues under environmentally friendly and safe conditions.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
