Description

Technical Field

[0001] The invention belongs to the technical field of oil fume purification, in particular to an oil fume purification device for a textile printing and dyeing setting machine. Background Art

[0002] The setting machine for textile printing and dyeing is one of the key finishing equipment in textile processing. Its main function is to make the fabric obtain stable size, shape and feel through heating, stretching, cooling and other treatment processes, thereby improving the quality and added value of the fabric. During the high-temperature setting process of the setting machine, the oil, dye additives and other substances contained in the fabric will evaporate due to heat and mix with hot air to form oil fume waste gas. These waste gases have complex components. If they are not effectively controlled and directly discharged into the atmosphere, the air quality will be reduced and environmental problems such as haze will be caused. Therefore, it is necessary to purify the oil fume before it is discharged.

[0003] The patent with announcement number CN208130655U discloses an oil fume purification device for a textile printing and dyeing setting machine, including an oil fume generating device, a smoke collecting hood, an air duct, a purifier, a fan chamber, a smoke outlet, and a secondary processing pipeline. A smoke collecting hood is fixedly arranged above the oil fume generating device, and the air duct is connected to the top of the smoke collecting hood. The air duct is connected to a reducing channel, and the reducing channel is connected to the purifier. The other side of the purifier is also connected to the reducing channel. The reducing channel on one side is connected to an air circulation pipeline in the secondary processing pipeline, and the secondary processing pipeline is connected to the fan chamber, and the fan chamber is connected to the smoke outlet. A fan is fixedly arranged inside the fan chamber, and a support rod is fixedly arranged below the inside of the secondary processing pipeline, and an air circulation pipeline is fixedly arranged above the support rod. Purification wet sheet fixing devices are fixedly arranged on the upper and lower sides of the air circulation pipeline. This utility model can process the oil fume multiple times, process it more cleanly, and can process the odor of the processed oil fume.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Since the specifications of the oil fume outlets of different setting machines are different, while the specifications of the fume hood are fixed, when the fume hood is close to the oil fume outlet, the specifications may not match, resulting in a gap between the edges of the two. When the oil fume is sucked, some of the oil fume will leak out through the gap, thereby affecting the amount of oil fume extracted, and the fume that is not extracted will be discharged elsewhere, causing environmental pollution.

[0006] To this end, the present invention provides an oil fume purification device for a setting machine for textile printing and dyeing. Summary of the invention

[0044] Specifically, the setting machine of textile printing and dyeing is one of the key finishing equipment in textile processing. Its main function is to make the fabric obtain stable size, shape and feel through heating, stretching, cooling and other processing processes, thereby improving the quality and added value of the fabric. During the high-temperature setting process of the setting machine, the grease, dye auxiliaries and other substances contained in the fabric will volatilize due to heat and mix with hot air to form oil fume exhaust gas. These exhaust gases have complex components. If they are not effectively controlled and directly discharged into the atmosphere, the air quality will be reduced and environmental problems such as haze will be caused. Therefore, it is necessary to purify the oil fume before it is discharged; the existing setting machines for textile printing and dyeing When the oil fume purification device is in use, the smoke is drawn through the smoke hood to enter the purifier for purification, and in order to ensure that the smoke can be drawn evenly, the smoke hood is brought close to the oil fume discharge port. However, since the specifications of the oil fume outlets of different setting machines are different, and the specifications of the smoke hood are fixed, when the smoke hood is close to the oil fume discharge port, the specifications may not match, resulting in a gap at the edge between the two. When the oil fume is drawn, part of the oil fume will leak out through the gap, thereby affecting the amount of oil fume drawn, and the smoke that is not drawn will be discharged elsewhere, causing environmental pollution;

[0045] Therefore, when the present embodiment is used, it is used for a rectangular oil fume exhaust port. According to the specifications of the oil fume exhaust port, the motor 6 19 is started to drive the gear 30 on one side to rotate, so that the gear ring 23 can be rotated, and multiple gears 30 can be rotated at the same time, and multiple adjustment blocks 29 can slide at the same time. Since the edges of adjacent adjustment blocks 29 are always in contact, multiple adjustment blocks 29 form rectangular through holes of different sizes, so that the adjustment blocks 29 can be in contact with the outer wall of the oil fume exhaust port. Then, the motor 31 is started to drive the threaded rod 2 41 to rotate, so that the lifting rod 10 can slide up and down, and the height of the air intake cylinder 9 is adjusted so that the through-hole plate 11 can be aligned with the oil fume exhaust port. Then, the exhaust fan 7 is started to allow the oil fume to enter the purification box 1 through the air intake pipe 8 and then pass through the ashtray. After the dust filter 38, large particles in the oil smoke can be intercepted, and after passing through the gas-liquid filter 39, tiny particles, oil mist and some water-soluble organic matter in the exhaust gas can be further filtered out. After passing through the activated carbon adsorption layer 40, extremely tiny particles, residual oil mist and unpleasant odors in the exhaust gas can be removed. Finally, the purified gas is discharged from the exhaust pipe 4; thus, the orientation of the multiple adjustment blocks 29 can be adjusted according to the specifications of the oil smoke discharge port, so that the multiple adjustment blocks 29 form rectangular through holes of different sizes, and the adjustment blocks 29 are fitted with the outer wall of the oil smoke discharge port to wrap the oil smoke discharge port, so that all the oil smoke can enter the purification box 1 through the air intake pipe 8, thereby avoiding the situation where the unextracted smoke is discharged to other places and then pollutes the environment;

[0046] Since the oil smoke enters from the rectangular through hole of the through hole plate 11, after the whole device has been used for a period of time, impurities will be attached to the inner wall of the rectangular through hole of the through hole plate 11. When the impurities accumulate too much, the through hole will be blocked, thereby affecting the air intake efficiency. Therefore, when the through hole plate 11 is not connected to the oil smoke exhaust port, the multiple adjustment blocks 29 are driven to move to a position aligned with the edge of the rectangular through hole. At this time, the area of ​​the rectangular plate 15 is the same as the through hole in the middle of the through hole plate 11. Then, the motor 25 is started to drive the threaded rod 1 27 to rotate, so that the threaded block 28 moves, the air intake cylinder 9 is away from the through hole plate 11, and the sealing gasket 13 is no longer in contact with the through hole plate 11. Then, under the action of the motor 4 36, the slide rod 18 is rotated, and the slide rod 18 drives the guide column 21 to slide in the slide groove of the slide plate 17, and with the cooperation of the sliding sleeve 20 and the limit rod 22, the guide column 2 1 will not deflect, so the L-shaped rod 16 can move forward first and then move to the right. When the rectangular plate 15 moves forward, it is aligned with the rectangular through hole in the middle of the through hole plate 11, and then moves to the right to pass through the rectangular through hole, and the edge fits with the inner wall of the rectangular through hole, so that the impurities attached to the inner wall can be pushed off and dropped into the collection box 12 for collection, so that the self-cleaning of the rectangular through hole can be achieved, avoiding the situation that the impurities block the through hole and thus affect the air intake efficiency. In addition, since the edge of the adjusting block 29 is aligned with the edge of the rectangular through hole, the edge of the rectangular plate 15 will also form a scrape with the inner edge of the adjusting block 29 to remove the impurities attached to the edge of the adjusting block 29, avoiding the situation that the adjusting block 29 and the outer wall of the oil fume exhaust port are not tightly fitted due to the impurities attached to the edge of the adjusting block 29 during subsequent use, and further ensuring the sealing performance;

[0047] Therefore, by utilizing the leak-proof self-cleaning air intake mechanism, the positions of multiple adjustment blocks 29 can be adjusted according to the specifications of the oil fume exhaust port, so that the multiple adjustment blocks 29 form rectangular through holes of different sizes, and the adjustment blocks 29 are fitted with the outer wall of the oil fume exhaust port to wrap the oil fume exhaust port, so that all the oil fume can enter the purification box 1 through the air intake pipe 8, thereby avoiding the unextracted smoke from being discharged elsewhere and polluting the environment. In addition, when impurities are attached to the inner wall of the rectangular through hole of the through hole plate 11, the impurities attached to the rectangular through hole in the middle of the through hole plate 11 and the inner edge of the adjustment block 29 can be removed by scraping and automatically collected, thereby avoiding the impurities blocking the through hole and affecting the air intake efficiency. It also avoids the situation in which the adjustment block 29 and the outer wall of the oil fume exhaust port are not tightly fitted due to impurities attached to the edge of the adjustment block 29 during subsequent use, thereby further ensuring the sealing.

[0048] In this embodiment, Figure 1 and Fig. 9As shown, a motor 5 is fixedly connected to the middle of the upper end surface of the purification box 1, and the output end of the motor 5 is fixedly connected to the rotating plate 32. The nozzle 35 is rotatably arranged on the annular tube 33. The middle of the left and right sides of the annular tube 33 are fixedly connected to a motor 5 37, and the output end of the motor 5 37 is fixedly connected to the nozzle 35;

[0049] A water tank 2 is fixedly connected to the upper side of the right end surface of the purification box 1, and a water pump 3 is connected to the upper end of the water tank 2. A hose 6 is connected to the liquid outlet of the water pump 3. The hose 6 penetrates the purification box 1 and is connected to the annular pipe 33.

[0050] Specifically, when the oil fume enters the purification box 1, the water pump 3 is started to pump out the water in the water tank 2, and the water is sprayed out from the nozzle 35 after passing through the hose 1 6, the annular tube 33, and the hose 2 34 to spray the oil fume, so as to adsorb the dust particles in the oil fume and drop them onto the dust filter 38 to filter the dust particles. At the same time, the motor 1 5 is used to drive the rotating plate 32 to rotate, so as to adjust the horizontal angle of the nozzle 35, and then the motor 5 37 is used to drive the nozzle 35 to rotate, so as to adjust the inclination angle of the nozzle 35, thereby expanding the spraying range of the nozzle 35, so that the dust particles in the oil fume can be evenly adsorbed, thereby improving the purification effect.

[0051] Working principle: According to the specifications of the oil fume exhaust port, the motor 6 19 is started to drive the gear 30 on one side to rotate, so that the gear ring 23 can be rotated, that is, multiple gears 30 can be rotated at the same time, and multiple adjustment blocks 29 can slide at the same time. Since the edges of adjacent adjustment blocks 29 are always in contact, multiple adjustment blocks 29 form rectangular through holes of different sizes, so that the adjustment blocks 29 can be in contact with the outer wall of the oil fume exhaust port, and then the motor 31 is started to drive the threaded rod 2 41 to rotate, so that the lifting rod 10 can slide up and down, and the adjustment The height of the air intake cylinder 9 is adjusted so that the through-hole plate 11 can be aligned with the oil fume discharge port, and then the exhaust fan 7 is started to allow the oil fume to enter the purification box 1 through the air intake pipe 8, and the water pump 3 is started to extract the water in the water tank 2, and the water is sprayed out from the nozzle 35 through the hose 1 6, the annular pipe 33, and the hose 2 34 to spray the oil fume, so that the dust particles in the oil fume can be adsorbed and dropped onto the dust filter 38 to filter the dust particles. At the same time, the motor 1 5 is used to drive the rotating plate 32 to rotate, and the oil fume can be sprayed. By adjusting the horizontal angle of the nozzle 35 and then using the motor 5 37 to drive the nozzle 35 to rotate, the inclination angle of the nozzle 35 can be adjusted, thereby expanding the spraying range of the nozzle 35, so that the dust particles in the oil smoke can be uniformly adsorbed, and the purification effect is improved; after passing through the dust filter 38, the large particles in the oil smoke can be intercepted, and after passing through the gas-liquid filter 39, the tiny particles, oil mist and some water-soluble organic matter in the exhaust gas can be further filtered out, and after passing through the activated carbon adsorption layer 40, the extremely tiny particles, residual oil mist and unpleasant odor in the exhaust gas can be removed. Finally, the purified gas is discharged from the exhaust pipe 4; thus, according to the specifications of the oil smoke discharge port, the orientation of the multiple adjustment blocks 29 can be adjusted, so that the multiple adjustment blocks 29 form rectangular through holes of different sizes, and the adjustment blocks 29 are fitted with the outer wall of the oil smoke discharge port to wrap the oil smoke discharge port, so that the oil smoke can all enter the purification box 1 through the air intake pipe 8, avoiding the situation where the unextracted smoke is discharged to other places and then pollutes the environment;Since the oil smoke enters from the rectangular through hole of the through hole plate 11, after the whole device has been used for a period of time, impurities will be attached to the inner wall of the rectangular through hole of the through hole plate 11. When too much impurities are accumulated, the through hole will be blocked, thereby affecting the air intake efficiency. Therefore, when the through hole plate 11 is not connected to the oil smoke exhaust port, the multiple adjustment blocks 29 are driven to move to a position aligned with the edge of the rectangular through hole. At this time, the area of ​​the rectangular plate 15 is the same as that of the through hole in the middle of the through hole plate 11. Then the motor 25 is started to drive the threaded rod 1 27 to rotate, so that the threaded block 28 moves, the air intake cylinder 9 is away from the through hole plate 11, and the sealing gasket 13 is no longer in contact with the through hole plate 11. Then, the motor 25 is started to drive the threaded rod 1 27 to rotate, so that the threaded block 28 moves, the air intake cylinder 9 is away from the through hole plate 11, and the sealing gasket 13 is no longer in contact with the through hole plate 11. Under the action of the machine four 36, the slide rod 18 rotates, and the slide rod 18 drives the guide column 21 to slide in the slide groove of the slide plate 17, and under the cooperation of the sliding sleeve 20 and the limit rod 22, the guide column 21 will not deflect, so that the L-shaped rod 16 can move forward first, and then move to the right. When the rectangular plate 15 moves forward, it is aligned with the rectangular through hole in the middle of the through hole plate 11, and then moves to the right, so that it can pass through the rectangular through hole, and the edge is in contact with the inner wall of the rectangular through hole, so that the impurities attached to the inner wall can be pushed off and dropped into the collection box 12 for collection, so that the self-cleaning of the rectangular through hole can be realized, and the impurities are prevented from blocking the through hole, thereby affecting the air intake. In addition, since the edge of the adjusting block 29 is aligned with the edge of the rectangular through hole, the edge of the rectangular plate 15 will also scrape against the inner edge of the adjusting block 29 to remove impurities attached to the edge of the adjusting block 29, thereby avoiding the situation in which the adjusting block 29 and the outer wall of the oil fume exhaust port are not tightly fitted due to impurities attached to the edge of the adjusting block 29 during subsequent use, thereby further ensuring the sealing performance; thereby, the anti-leakage self-cleaning air intake mechanism can be used to adjust the positions of multiple adjusting blocks 29 according to the specifications of the oil fume exhaust port, so that the multiple adjusting blocks 29 form rectangular through holes of different sizes, and the adjusting blocks 29 are fitted with the outer wall of the oil fume exhaust port, To wrap the oil fume discharge port, so that all the oil fume can enter the purification box 1 through the air intake pipe 8, avoiding the unextracted smoke from being discharged to other places and polluting the environment. In addition, when impurities are attached to the inner wall of the rectangular through hole of the through hole plate 11, the impurities attached to the rectangular through hole in the middle of the through hole plate 11 and the inner edge of the adjustment block 29 can be removed by scraping and automatically collected, avoiding the impurities blocking the through hole and affecting the air intake efficiency. It also avoids the situation in which the adjustment block 29 and the outer wall of the oil fume discharge port are not tightly attached due to impurities attached to the edge of the adjustment block 29 during subsequent use, further ensuring the sealing. ;
