Description

Technical Field

[0001] The invention relates to the technical field of waste gas purification, and in particular to a waste gas purification system for release paper laminating equipment. Background Art

[0002] Release paper is widely used. It is usually made of paper or film coated with anti-sticking material. It can prevent the adhesion of prepregs, protect the prepregs from contamination, and facilitate storage and use. Release paper is generally used with sticky materials, especially tapes and stickers. Release paper usually includes a base paper layer and a coating layer. The coating production usually produces oil smoke. If the waste gas is discharged directly, it will pollute the surrounding air. Therefore, the waste gas needs to be purified.

[0003] After searching, the patent document with the announcement number CN118384627B discloses an exhaust gas purification system for release paper laminating equipment, including a purification box and a filter installed inside the purification box. The device is designed with a hook surface layer and a fleece surface layer for connection, which facilitates the rapid installation and replacement of the oil filter. During the operation of the exhaust fan, the reciprocating screw rod is driven to rotate, and the oil scraper is driven to move back and forth, thereby driving the corrugated scraper to timely scrape the oil stains on the surface of the corrugated oil filter plate.

[0004] However, the above patents still have the following defects: For example, the exhaust and the corrugated oil filter plate cleaning cannot be used separately and decoupled. The cleaning of the corrugated oil filter plate in this application is achieved by scraping and spraying. The airflow generated when the exhaust fan is running will interfere with the distribution of the atomized particles of the cleaning liquid, resulting in the surface of the corrugated oil filter plate, especially the complex folds, not being fully infiltrated, forming a cleaning blind spot, resulting in oil and dirt easily remaining, requiring frequent cleaning, and shortening the life of the corrugated oil filter plate. In addition, the atomized cleaning liquid will enter the control box, sensor or solenoid valve with the airflow, causing short circuit or corrosion, especially when using acidic / alkaline cleaning agents, resulting in an increase in equipment failure rate and maintenance costs. Therefore, the fan and spray cleaning cannot effectively clean the corrugated oil filter plate, affecting the exhaust gas purification effect. Therefore, an exhaust gas purification system for release paper laminating equipment is proposed to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 7 In this embodiment, an exhaust gas purification system for release paper laminating equipment includes a filter housing 1, an exhaust fan 2 and a filter plate 5 detachably mounted inside the filter housing 1, a partition 4 is fixed inside the filter housing 1, and a gas pipeline 3 connected to the exhaust fan 2 is fixed inside the partition 4. It should be noted that the partition 4 divides the interior of the filter housing 1 into two parts, the filter plate 5 is located below the partition 4, and an air entrainment structure is fixed on the back of the filter housing 1 so that the gas is discharged after being filtered by the filter plate 5. A sealing valve is provided on the air entrainment structure.

[0024] In order to achieve efficient purification, a cleaning mechanism 9 for cleaning the filter plate 5 is provided on the partition 4, and a driving mechanism for driving the exhaust fan 2 and the cleaning mechanism 9 is installed on the top side of the filter housing 1; wherein the driving mechanism includes a dual-axis motor 6, two first synchronous wheels 7 and a first synchronous belt 8, the two first synchronous wheels 7 are respectively installed on the top output shaft of the dual-axis motor 6 and the exhaust fan 2, and the first synchronous belt 8 is connected between the two first synchronous wheels 7. The exhaust fan 2 is decoupled from the cleaning function by the dual-axis motor 6, and the exhaust fan 2 is stopped during cleaning, and only the reciprocating motion of the scraper 33 is retained. This integrated design reduces the number of required motors, simplifies the system structure, reduces costs, and improves the overall compactness.

[0025] Specifically, the cleaning mechanism 9 is composed of a reciprocating structure, a liquid storage structure, an infusion pump 30, a scraper 33 and a linkage structure. It should be noted that the reciprocating structure is started by the driving mechanism and is respectively used in linkage with the liquid storage structure, the infusion pump 30 and the scraper 33, and one side of the scraper 33 is against the outer surface of the filter plate 5. This linkage design enables the various parts of the cleaning mechanism 9 to work together, improves the cleaning efficiency, and ensures the cleanliness of the filter plate 5.

[0026] In this embodiment, the reciprocating structure includes a rotating shaft 10 and a rotating drum 15 rotatably mounted inside the filter housing 1, a rotating disk 11 fixed to the bottom end of the rotating shaft 10, a reciprocating rod 14 movably penetrating the inside of the rotating drum 15, and a sliding seat 18 slidably connected to the outside of the rotating drum 15. In order to realize the driving of the reciprocating structure, a transmission member is arranged between the bottom output shaft of the dual-axis motor 6 and the reciprocating structure; wherein the transmission member includes a transmission gear 12 fixed on the bottom output shaft of the dual-axis motor 6 and a driven gear 13 fixed on the outer surface of the top end of the rotating shaft 10, the driven gear 13 meshes with the transmission gear 12, and the diameter of the driven gear 13 is larger than the transmission gear 12. The diameter of the driven gear 13 is larger than the transmission gear 12, which realizes the amplification of the transmission ratio, so that the rotation speed of the rotating shaft 10 is lower than the output shaft speed of the dual-axis motor 6. This speed regulation helps to adapt to the working requirements of the cleaning mechanism 9, ensure that the moving speed of the scraper 33 on the filter plate 5 is moderate, and can effectively clean impurities without causing excessive wear to the filter plate 5.

[0027] In this embodiment, the top of the rotating shaft 10 is connected to the top wall bearing of the filter housing 1, and a connecting arm 16 is hinged on the lower surface of the rotating disk 11. The other end of the connecting arm 16 is fixed with a universal ball joint 17 that is rotatably connected to the top of the rotating shaft 10, and the connecting arm 16 is set in an inclined shape. The design of the connecting arm 16 and the universal ball joint 17 hinged on the lower surface of the rotating disk 11 allows the connecting arm 16 to swing flexibly with the rotation of the rotating disk 11, while maintaining a stable connection with the rotating shaft 10, thereby enhancing the adaptability of the mechanism. A reciprocating groove 21 connected to the outer surface is provided inside the rotating drum 15, and a ball bearing that slides with the reciprocating groove 21 is fixed on the outer surface of the slide seat 18, and a limit seat 22 that guides the slide seat 18 is fixed on the inner wall of the filter housing 1.

[0028] Specifically, a first connecting rod 19 is fixed to the outer surface of the bottom end of the reciprocating rod 14, a second connecting rod 20 connected to the first connecting rod 19 is fixed to the side of the slide 18 away from the reciprocating slide 21, and a fourth connecting rod 35 is fixed between the scraper 33 and the first connecting rod 19. The liquid storage structure includes a liquid storage cylinder 23 fixed to the inside of the filter housing 1, a transmission shaft 24 rotatably installed inside the liquid storage cylinder 23, and a stirring rod sleeve 25 sliding on the outer surface of the transmission shaft 24, the transmission shaft 24 and the stirring rod sleeve 25 are spline-connected, and a third connecting rod 28 extending to the inside of the liquid storage cylinder 23 is fixed to one end of the first connecting rod 19 away from the reciprocating rod 14. A liquid infusion tube extending into the side wall of the filter housing 1 and connected to the liquid storage cylinder 23 can also be installed. A liquid level sensing device is installed in the liquid storage cylinder 23. A sealing gasket is provided at the connection between the third connecting rod 28 and the liquid storage cylinder 23.

[0029] When in use, the liquid storage cylinder 23 is used to store the cleaning liquid. The spline connection design between the transmission shaft 24 and the stirring rod sleeve 25 enables the stirring rod sleeve 25 to slide along its axial direction when the transmission shaft 24 rotates, while maintaining synchronous rotation in the circumferential direction. The connection between the third connecting rod 28 and the connecting sleeve 29 transmits the reciprocating motion of the first connecting rod 19 to the stirring rod sleeve 25, so that the cleaning liquid in the liquid storage cylinder 23 is effectively stirred while the scraper 33 performs the cleaning action, thereby ensuring the uniformity and activity of the cleaning liquid.

[0030] In addition, through the connection between the first connecting rod 19, the second connecting rod 20 and the fourth connecting rod 35, the reciprocating motion of the reciprocating rod 14 is not only transmitted to the scraper 33, so that it can perform stable reciprocating cleaning on the filter plate 5, but also can drive the rotating drum 15 to rotate through the sliding cooperation between the slide seat 18 and the reciprocating slide groove 21, and the second synchronous wheel 26 and the second synchronous belt 27 are used to stir the cleaning liquid. At the same time, the third connecting rod 28 is used to drive the stirring rod sleeve 25 to reciprocate and rise and fall, so as to further improve the stirring effect of the cleaning liquid, so that the reciprocating motion of the scraper 33 can more effectively remove impurities on the filter plate 5, and the stirred cleaning liquid can provide a better cleaning effect.

[0031] In order to improve the activity of the cleaning liquid, the bottom end of the stirring rod sleeve 25 is rotated with a connecting sleeve 29 fixed to the end of the third connecting rod 28. The linkage structure includes two second synchronous wheels 26 and a second synchronous belt 27 connected between the two second synchronous wheels 26. The two second synchronous wheels 26 are respectively fixed to the outer surface of the top end of the liquid storage cylinder 23 and the transmission shaft 24. The two second synchronous wheels 26 are set in different sizes.

[0032] In order to realize the delivery of cleaning liquid, the infusion pump 30 includes a valve tube 3001 fixed on the upper surface of the partition 4, a valve shell 3002 fixedly connected to the upper surface of the valve tube 3001, and a diaphragm 3003 fixed inside the valve shell 3002. The upper surface of the diaphragm 3003 is fixed with a valve stem 3005 extending to the outside of the valve shell 3002, and the top of the valve stem 3005 is fixed to the bottom end of the reciprocating rod 14. The left and right ends of the valve tube 3001 are respectively fixed with a corrugated hose 31 and a connecting tube 32. The other end of the connecting tube 32 is fixedly connected to the bottom side of the liquid storage cylinder 23.

[0033] Specifically, a nozzle 34 is fixed to the side of the scraper 33 away from the filter plate 5, and one end of the corrugated hose 31 away from the valve tube 3001 is fixedly connected to the nozzle 34. A reset spring 3006 is fixed between the outer surface of the bottom end of the valve stem 3005 and the inner wall of the valve housing 3002, and two check valves 3004 are elastically hinged inside the valve tube 3001. The design of the infusion pump 30 cleverly utilizes the reciprocating motion of the reciprocating rod 14. When the reciprocating rod 14 moves up and down, the diaphragm 3003 is driven to move up and down in the valve housing 3002 through the valve stem 3005. The up and down movement of the diaphragm 3003 causes the pressure in the valve tube 3001 to change, and the action of the check valve 3004 is used to achieve the suction and discharge of the cleaning liquid, and the reset spring 3006 ensures that the diaphragm 3003 and the valve stem 3005 are quickly reset after the reciprocating rod 14 ends its movement, thereby ensuring the continuous operation of the infusion pump 30.

[0034] It should be noted that the reciprocating distance of the slide 18 is adapted to the length of the filter plate 5, and the agitation amplitude of the diaphragm 3003 is adapted to the reciprocating distance of the slide 18. The entire design uses fewer components to achieve complex functions, such as the infusion pump 30 achieves the delivery of the cleaning liquid through the simple combination of the diaphragm 3003 and the check valve 3004, and the connection between the mechanical structures is compact and firm, such as the spline connection between the stirring rod sleeve 25 and the transmission shaft 24, the fixed connection between the second synchronous wheel 26 and the transmission shaft 24 and the liquid storage cylinder 23, etc., all of which enhance the reliability and durability of the mechanism.

[0035] The working principle of the above embodiment is: The exhaust fan 2 is decoupled from the cleaning function by the dual-axis motor 6. When cleaning, the exhaust fan 2 is stopped, and only the reciprocating motion of the scraper 33 is retained. The bottom output shaft of the dual-axis motor 6 is driven. The bottom output shaft of the dual-axis motor 6 is driven through the transmission gear 12 and the driven gear 13 to drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the rotating disk 11 to rotate. Through the linkage of the connecting arm 16 and the universal ball joint 17, the reciprocating rod 14 generates reciprocating motion. When the reciprocating rod 14 reciprocates, it drives the valve stem 3005 and the slide seat 18 to reciprocate respectively. When the slide 18 reciprocates, it moves in the reciprocating slide 21, thereby driving the drum 15, so that the drum 15 rotates accordingly. When the drum 15 rotates, the second synchronous wheel 26 and the second synchronous belt 27 drive the stirring rod sleeve 25 to slide and rotate on the transmission shaft 24, so as to stir the cleaning liquid in the liquid storage cylinder 23. At the same time, the reciprocating rod 14 uses the first connecting rod 19, the third connecting rod 28 and the fourth connecting rod 35 to drive the scraper 33 and the stirring rod sleeve 25 to reciprocate respectively. The reciprocating motion of the stirring rod sleeve 25 will further enhance the stirring of the cleaning liquid and improve the activity of the cleaning liquid. The scraper 33 moves back and forth. When the valve stem 3005 moves upward, the pressure in the valve housing 3002 decreases, the check valve 3004 opens, and the cleaning liquid in the liquid storage cylinder 23 enters the nozzle 34 through the connecting pipe 32, the valve pipe 3001 and the corrugated hose 31; when the valve stem 3005 moves downward, the pressure in the valve housing 3002 increases, the check valve 3004 closes, and the cleaning liquid is sprayed on the filter plate 5 through the nozzle 34, and the scraper 33 is assisted to clean.

[0036] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods. Any connection method can be implemented as long as it can achieve its beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. The technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
