Description

Technical Field

[0001] The utility model relates to the technical field of workshop deodorization, in particular to an exhaust gas discharge device on a drying machine. Background Art

[0002] Printing workshops mainly use various printing equipment to copy designed graphic information onto various substrates such as paper, plastic, and fabric to achieve large-scale and standardized printing production; among them, printing equipment includes dry laminating machines, pad printing machines, screen printing machines, offset printing machines, flexographic printing machines, gravure printing machines, UV printing machines, etc. These equipment may produce some irritating odors under certain conditions and processing. For example, the main function of a dry laminating machine is to bond different materials together with adhesives. The process involves the coating, drying, and final lamination of adhesives. This series of process steps usually releases a variety of volatile organic compounds (VOCs), including but not limited to solvent components in solvent-based adhesives, by-products produced by thermal reactions, and incompletely cured adhesive components; and these VOCs often have irritating odors, which will pollute the air in the workshop, reduce the comfort of the working environment, and even pose a potential threat to the health of workers. Therefore, in response to the pungent odor produced by the dry duplication machine, our company installed a set of exhaust gas emission devices in the original workshop to effectively exhaust the pungent odor in the printing workshop to ensure the air quality and sanitary environment of the factory. Utility Model Content

[0003] The utility model provides an exhaust gas exhaust device on a dry laminating machine, which can solve the problem that the irritating odor generated by the operation of printing equipment in a printing workshop reduces the air quality of the workshop and the comfort level of the working environment.

[0004] This application provides the following technical solutions:

[0005] A waste gas discharge device on a dryer comprises a waste gas discharge pipeline and a support frame, wherein an air collecting hood is arranged on the top of each dryer, an air inlet of the waste gas discharge pipeline is connected to the air collecting hood, and an air outlet of the waste gas discharge pipeline is located outside the factory building and is connected to an exhaust fan; the waste gas discharge pipeline comprises a main pipe and a plurality of branch pipes, the main pipe is fixed on the top of the wall, one end of each branch pipe is connected to the air collecting hood, and the other end is connected to the main pipe, and an installation component for fixing the branch pipe is also arranged on the support frame; the installation component comprises two limit rods and a pressure plate slidably arranged on the two limit rods, the two limit rods and the pressure plate form an installation channel, the branch pipe passes through the installation channel and is locked by the pressure plate, and rubber pads are also arranged on the side walls where the limit rods, the pressure plate and the branch pipe are in contact.

[0006] Beneficial effects:

[0007] 1. By setting a gas collecting hood on the top of each dryer, it is helpful to collect the exhaust gas generated when the dryer is working. The exhaust gas in the gas collecting hood is discharged out of the factory through the exhaust gas discharge pipeline through the exhaust fan, and the exhaust gas is treated outside the factory and then discharged into the atmosphere. The irritating odor generated by the dryer when working can be discharged in time and effectively, thereby ensuring the air quality of the factory and the comfort of the working environment.

[0008] 2. By arranging the installation components on the support frame to fix the branch pipe, the stability of the branch pipe connection can be ensured, and the slight shaking or abnormal noise caused by the vibration during ventilation can be reduced. In addition, after the branch pipe is fixed, it can also support the main pipe and improve the stability of the main pipe installation.

[0009] 3. The pressure plate is slidably set on two limit rods, which can be adjusted according to the size of the branch pipe, and the installation and fixing method is simple; in addition, rubber pads are set on the side walls where the limit rod, the pressure plate and the branch pipe are in contact, which can play a buffering and protective role, thereby reducing friction and wear, and also reducing the problem of branch pipe vibration caused by ventilation.

[0010] Furthermore, the support frame includes a crossbeam and a column, and a triangular auxiliary bracket is also arranged on one side of the crossbeam close to the gas collecting hood, and the mounting assembly is arranged on the auxiliary bracket.

[0011] Beneficial effects: By arranging an auxiliary bracket on the support frame, the interference problem caused by the support frame being too close to the drying machine can be reduced; arranging a triangular auxiliary bracket is beneficial to improving the stability and strength of the bracket.

[0012] Furthermore, the branch pipe includes a horizontal pipe section and a vertical pipe section, and the mounting assembly is used to fix the horizontal pipe section; the horizontal pipe section is connected to the air collecting hood through a bellows.

[0013] Beneficial effects: The bellows has great flexibility and ductility. The bellows is arranged at the connection between the gas collecting hood and the horizontal pipe section, which is convenient for installation and adjustment of the orientation, and is also conducive to ensuring the sealing of the installation.

[0014] Furthermore, the exhaust gas emission pipeline is installed on the top of the factory building, and a suspended ceiling is also provided on the top of the wall of the factory building; the main pipe is located between the top of the wall and the suspended ceiling, and is fixed on the top of the wall by a mounting frame, and the vertical pipe section of the branch pipe passes through the suspended ceiling and is connected to the main pipe.

[0015] Beneficial effects: Setting the main pipe between the wall top and the ceiling is conducive to ensuring the aesthetics of the factory building, and is convenient for installing the main pipe on the wall top, which can reduce the number of support frames and the factory space occupied by the support frames, and the layout is more reasonable.

[0016] Furthermore, a flexible installation sleeve is provided at the connection between the vertical pipe section and the suspended ceiling. The installation sleeve includes an inner sleeve and an outer sleeve with a T-shaped longitudinal section. The T-shaped horizontal edges of the inner sleeve and the outer sleeve are fixedly connected to the suspended ceiling; the outer sleeve is sleeved on the inner sleeve and threadedly connected to the outer wall of the inner sleeve. A rubber layer is provided on the inner wall of the inner sleeve. The vertical pipe section passes through the inner sleeve and the outer sleeve, and the inner sleeve is fixed to the vertical pipe section under the action of the outer sleeve.

[0017] Beneficial effects:

[0018] 1. The vertical pipe section is fixed to the installation hole of the suspended ceiling through a flexible installation sleeve. Compared with the rigid flange connection structure, the flexible installation sleeve can play a certain shock-absorbing role, thereby reducing the friction or abnormal noise caused by vibration, and reducing the impact of branch pipe vibration on the suspended ceiling.

[0019] 2. By arranging a rubber layer on the inner wall of the inner sleeve, on the one hand, the vibration of the vertical pipe section caused by ventilation can be further reduced, which plays a role of buffering protection. On the other hand, the friction between the inner sleeve and the outer wall of the vertical pipe section can be increased, thereby improving the stability of the connection between the installation sleeve and the vertical pipe section.

[0020] 3. By putting the outer sleeve on the inner sleeve and connecting it with the inner sleeve by thread, the outer sleeve is used to squeeze the inner sleeve so that it is tightly held with the vertical pipe section. The connection method is simple and has high strength, and the connection strength between the inner sleeve and the vertical pipe section and between the inner sleeve and the outer sleeve can be ensured at the same time.

[0021] Furthermore, sealing rings are provided on the end surfaces of the inner sleeve and the outer sleeve that are in contact with the vertical pipe section.

[0022] Beneficial effect: By setting the sealing ring, the sealing performance between the vertical pipe section and the end of the casing can be ensured, and the shock absorbing effect can be further achieved.

[0023] Furthermore, rubber rings are provided on the end surfaces of the inner sleeve and the outer sleeve that are in contact with the horizontal surface of the suspended ceiling.

[0024] Beneficial effect: The rubber ring can reduce the wear between the sleeve and the ceiling, and seal the gap between the sleeve and the ceiling installation hole, thereby ensuring the sealing of the pipeline installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The exhaust gas emission pipeline includes a main pipe 2 and several branch pipes 21. In actual use, multiple branch pipes 21 can be set on the air collecting hood 201 of each dryer 200; the main pipe 2 is fixed on the top of the wall, one end of each branch pipe 21 is connected to the air collecting hood 201, and the other end is connected to the main pipe 2; specifically in this embodiment, the exhaust gas emission pipeline is installed on the top of the factory building 100, and the top of the wall of the factory building 100 is also provided with a suspended ceiling 101, the main pipe 2 is located between the top of the wall and the suspended ceiling 101, and is fixed to the top of the wall through a mounting frame 3.

[0034] like Figure 2 As shown, the support frame 1 includes a crossbeam 12 and a column 11. The crossbeam 12 is arranged along the length direction of the plurality of drying machines 200, and a triangular auxiliary bracket 4 is fixed by bolts on one side of the crossbeam 12 close to the gas collecting hood 201. A mounting assembly 5 is fixed on the auxiliary bracket 4 by bolts. The mounting assembly 5 is used to fix the branch pipe 21. Figure 3As shown, the mounting assembly 5 includes two limit rods 51 and a pressure plate 52 slidably arranged on the two limit rods 51. The two limit rods 51 and the pressure plate 52 form a mounting channel. The branch pipe 21 passes through the mounting channel and is locked by the pressure plate 52. Specifically, the limit rod 51 is a threaded rod, and the pressure plate 52 is locked by screwing a nut. Rubber pads 512 are also arranged on the side walls where the limit rods 51 and the pressure plate 52 contact the branch pipe 21. The rubber pads 512 can play a role of buffering protection, thereby reducing friction and wear, and at the same time can also reduce the problem of vibration of the branch pipe 21 caused by exhaust.

[0035] The branch pipe 21 of this embodiment includes a horizontal pipe section 211 and a vertical pipe section 212. The horizontal pipe section 211 is connected to the gas collecting hood 201 through a corrugated pipe 2110. The mounting assembly 5 is used to fix the horizontal pipe section 211. The vertical pipe section 212 passes through the ceiling 101 and is connected to the main pipe 2. A flexible mounting sleeve 6 is also provided at the connection between the vertical pipe section 212 and the ceiling 101. Figure 4 As shown, the flexible installation sleeve 6 is a nylon sleeve, and the installation sleeve 6 includes an inner sleeve 61 and an outer sleeve 62 with a T-shaped longitudinal section. The T-shaped horizontal edges of the inner sleeve 61 and the outer sleeve 62 are fixedly connected to the ceiling 101 by bolts; the outer sleeve 62 is sleeved on the inner sleeve 61 and is threadedly connected to the outer wall of the inner sleeve 61, and a rubber layer 611 is provided on the inner wall of the inner sleeve 61.
