Description

Technical Field

[0001] The invention relates to the technical field of hot melt adhesive coating, in particular to a smoke adsorption purifier for hot melt adhesive coating cooling. Background Art

[0002] Hot melt adhesive coating is a chemical process, also known as hot melt or hot melt coating. It is done by heating and melting some organic matter into a liquid and then coating the substrate. The coated paper web is cooled in a cooler or cold cylinder, and the molten coating forms a coating on the substrate, which is then wound and processed into a finished product. This process has the characteristics of no environmental pollution and fast coating speed. During the cooling process of the coating, the surface of the coating winding cooling roller is cooled. When the high temperature coating is cooled rapidly by the cooling material, smoke will be generated. It will also contain particles, water vapor, toxic and harmful substances, etc. Direct discharge will cause pollution.

[0003] The utility model with announcement number CN213699432U discloses a smoke purification device for a fabric setting machine for printing and dyeing. By setting a smoke purification box and setting the smoke purification chamber as a physical adsorption chamber, a chemical-physical adsorption chamber and a water washing chamber, the harmful substances in the smoke can be fully removed by combining physical adsorption and chemical absorption. Finally, the smoke is washed with water to make the gas discharged by the suction fan purer. By setting a smoke drying box, the smoke after water washing can be fully dried so that the gas discharged by the air pump can not change the humidity of the air.

[0004] The utility model with announcement number CN217526915U discloses an oil fume purification device for fabric production. The water in the water storage chamber is discharged through a drain pipe, thereby circulating the water in the water pipe. The heat is absorbed by the cold water circulation, so that the condensation plate always maintains a low temperature state, so that the oil droplets can condense better and flow into the oil storage tank to remove the oil fume in the exhaust gas; no water spraying is required, which can effectively save water and avoid the generation of wastewater.

[0005] However, the smoke adsorption purifier used in the coating process still has the following problems during actual use: although the built-in purification material can filter out odors and other substances, this type of smoke adsorption purification mechanism cannot effectively filter water vapor in the smoke, and part of the water vapor is adsorbed in the purification filter element, affecting the purification effect, resulting in high humidity inside the overall smoke adsorption purifier for a long time. At the same time, the toxic and harmful substances in the smoke are only removed by adsorption, the purification process is relatively simple, and the discharged gas contains harmful substances that cannot be adsorbed by water.

[0006] Therefore, we propose a smoke adsorption purifier for hot melt adhesive coating cooling to solve the above problems. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the smoke adsorption purifier for hot melt adhesive coating cooling uses an expanded adsorption cover arranged above the cooling roller to adsorb smoke, and the anti-condensation scraper and anti-condensation slide plate inside the purifier clean the flying catkins and water vapor filtered in the smoke to avoid residual cross contamination. At the same time, the smoke inside the purifier body is circulated and sprayed, and then the purification filter layer achieves efficient purification and discharge. The specific contents are as follows:

[0021] 1. The negative pressure guide fan module works, applying hot melt adhesive on the smoke generated after cooling by the cooling roller to absorb it, so that the smoke enters the flared adsorption cover. The water vapor filter layer filters the water vapor in the smoke and the floating catkins. The filtered smoke continues to enter the interior of the purifier body through negative pressure for subsequent purification.

[0023] 2. The anti-condensation scraper drives the flying catkins and water vapor to move to the side of the flared adsorption cover, then pushes the closed flip plate upwards, and then enters the interior of the condensation recovery box through the opened push slot. The traction cable loosens the connected anti-condensation slide plate and slides it inward, scraping off the stored flying catkins and water vapor through the fitted anti-condensation slide plate to avoid residual cross-contamination of the anti-condensation scraper during the subsequent cleaning process.

[0024] Flying catkins and water vapor are stored inside the condensation recovery box to ensure the cleanliness of the anti-condensation scraper.

[0025] 3. The water-proof bushing and the guide baffle block the rising smoke and make it enter the bottom of the purifier body. The incomplete gear drives the gear to intermittently mesh, and the driving gear drives the driving shafts and purification nozzles on the front and rear sides to swing, so as to spray and purify the harmful substances and odors in the smoke.

[0026] 4. The spray purification water is pumped to the circulating water tank for filtration and circulated to the purification nozzle for spraying operation. The smoke passes through the guide baffle and is filtered and purified by the purification filter layer, and is discharged to the outside of the purifier body by the negative pressure guide fan module.

[0041] The adsorption mechanism includes a bidirectional threaded rod 7, and the bidirectional threaded rod 7 is rotatably arranged above the interior of the flared adsorption cover 4 through a bearing. The left end of the bidirectional threaded rod 7 is connected to the right end of the cooling roller 2 through a main pulley assembly 8. The left and right outer walls of the bidirectional threaded rod 7 are both threaded with anti-condensation scrapers 9.

[0042] like Figures 1-4 As shown, the cooling roller 2 above the cooling bracket 1 rotates, and its internal circulation is cooled, and the coating adheres to the upper surface of the cooling roller 2 after heating and conveying, thereby generating smoke and rising upward, and the negative pressure guide fan module 22 arranged on the top surface of the purifier body 6 works so that the bottom of the expanded adsorption cover 4 connected through it is in a negative pressure state to absorb the smoke into the inside.

[0043] like Figure 4-Figure 5 As shown, the water vapor filter layer 13 arranged above the inside of the flared adsorption cover 4 filters the water vapor in the smoke and the floating catkins so that they are collected above the water vapor filter layer 13. During the rotation, the rotating cooling roller 2 drives the two-way threaded rod 7 engaged inside the flared adsorption cover 4 to rotate through the main pulley assembly 8 at the left end, so that the threaded anti-condensation scraper 9 cleans the water vapor filter layer 13 that is stuck with water vapor and flying catkins so that they are stored inside the anti-condensation scraper 9 for recycling.

[0044] Example 2: In order to solve the problems existing in the use of smoke adsorption purifiers during the existing coating cooling process, this embodiment adopts the following technical solutions: the adsorption mechanism includes a closed flip plate 10, and the closed flip plate 10 is rotatably arranged on the left and right sides of the outside of the flared adsorption cover 4 through bearings, and the left and right ends of the flared adsorption cover 4 are provided with push slots 11, and the closed flip plate 10 is used to achieve an openable sealing effect for the push slots 11; the adsorption mechanism includes an anti-condensation slide plate 12, and the anti-condensation slide plate 12 is elastically slidably arranged on the front and back sides of the interior of the condensation recovery box 5, and the outer ends of the symmetrically arranged anti-condensation slide plates 12 are fixedly connected to the outer end of the traction steel cable 24, and the inner end of the traction steel cable 24 is fixedly connected to the outer wall of the closed flip plate 10, and the rotation of the closed flip plate 10 is used to drive the anti-condensation slide plate 12 to move inward to achieve contact.

[0046] like Figure 6-Figure 8 As shown, after the anti-condensation scraper 9 containing flying catkins and water vapor moves to the side of the flared adsorption cover 4, the closed flip plate 10 connected to it is flipped upward to open the previously covered push slot 11 so that the anti-condensation scraper 9 is moved to the inside of the condensation recovery box 5. At the same time, the rotation of the closed flip plate 10 loosens the anti-condensation slide plate 12 connected to the traction cable 24, so that the anti-condensation slide plate 12 is not pulled and moves synchronously inward to fit the surface of the anti-condensation scraper 9. At the same time, after the anti-condensation scraper 9 moves in the opposite direction, the stored flying catkins and water vapor are scraped off through the fitted anti-condensation slide plate 12 so that they are stored in the inside of the condensation recovery box 5, ensuring the cleanliness of the anti-condensation scraper 9. After moving to the inside of the flared adsorption cover 4 again, the pushing slot 11 is covered by the closed flip plate 10 to prevent smoke from overflowing from the flared adsorption cover 4 and affecting the purification effect.
