Abstract
Description
Technical Field
[0001] This utility model relates to the field of NMP recovery and waste gas treatment technology, and in particular to an integrated device for dual-rotor NMP recovery and waste gas emission compliance. Background Technology
[0002] The dual-rotor NMP recovery and exhaust gas emission standard compliance integrated equipment is an environmental protection device that combines N-methylpyrrolidone (NMP) solvent recovery and exhaust gas purification functions. It is mainly used in industries such as lithium batteries, electronics, chemicals, and pharmaceuticals for NMP solvent recovery and exhaust gas treatment. During operation, in order to improve the service life of the rotors and the dehumidification and purification effect, the equipment needs to use a filter structure to perform preliminary filtration of the incoming air containing NMP solvent. After long-term use, a large amount of dust will adhere to the surface of the filter screen, reducing the permeability of the filter screen and reducing the amount of air entering the rotor mechanism. When the filter structure becomes clogged, the machine needs to be stopped for cleaning or replacement. This shutdown for maintenance will cause production interruption, affecting continuity and economy. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Please see Figures 1 to 9 This embodiment provides an integrated device for dual-rotor NMP recovery and exhaust gas emission compliance, including a frame 1. The internal structure of the frame 1, from front to back, consists of a baffle 4, a filter plate 2, an adsorption fan 17, an adsorption rotor 18, a burner 19, and a desorption fan 20. The threaded rod 7 and the collection frame 21 are both located between the front side of the filter plate 2 and the rear side of the baffle 4. The collection frame 21 is located directly below the front cleaning rod 9. The motor 14 and the gear 15 are located on the rear side of the baffle 4. A filter plate 2 is detachably installed on the front side of the inner cavity of the frame 1. The left and right sides of the front side of the outer surface of the frame 1 are provided with mounting grooves 3. A baffle 4 is detachably installed in the inner cavity of the mounting groove 3. The top of the mounting groove 3 penetrates the top side of the frame 1. The bottom of the mounting groove 3 is at the same level as the bottom of the inner cavity of the frame 1. The outer surface of the baffle 4 is made of synthetic rubber. When in use, the irregular shape of the vertical cross section of the baffle 4 and the vertical cross section of the mounting groove 3 are matched. The rubber material of the outer surface of the baffle 4 makes the baffle 4 only able to move horizontally left and right after installation. At the same time, the elastic deformation of the rubber material fills the gap between the baffle 4 and the mounting groove 3. Multiple teeth 5 are fixedly installed on the top of the rear side of the baffle 4. Grooves 401 are provided on both the left and right sides of the top of the baffle 4. The leftmost tooth 5 is rotatably mounted to the left side of the inner cavity of the left groove 401 via a torsion shaft, and the rightmost tooth 5 is rotatably mounted to the right side of the inner cavity of the right groove 401 via a torsion shaft. The distribution and shape of the teeth 5 match the shape of the outer surface of the gear 15. The distance between the leftmost and rightmost teeth 5 is greater than the width between the leftmost and rightmost filter holes in the left opening area of the filter plate 2. Therefore, during use, the gear 15 rotates, driving the baffle 4 to move left or right through the teeth 5. Utilizing the distance between the leftmost and rightmost teeth 5, the baffle 4 can be completely moved to the left or right. The left opening of the filter plate 2 is either not blocked or the left opening of the filter plate 2 is completely blocked. At the same time, the rightmost tooth 5 is rotatably connected to the right side of the inner cavity of the right groove 401 through the torsion shaft. When the gear 15 rotates clockwise, it drives all the teeth 5 to move to the left, causing the baffle 4 to move to the leftmost side. At this time, if the gear 15 continues to rotate clockwise, it will only rotate and squeeze the rightmost tooth 5 into the inner cavity of the rightmost groove 401, thus causing the baffle 4 to be unable to move to the left. That is, the gear 15 rotates clockwise and the baffle 4 no longer moves to the left. Similarly, when the gear 15 rotates counterclockwise and moves the baffle 4 to the rightmost side, the gear 15 pushes the leftmost tooth 5 to rotate and squeeze into the inner cavity of the left groove 401. At this time, the baffle 4 cannot move to the right and the gear 15 can still continue to rotate counterclockwise. A left push block 6 is fixedly installed on the left side of the top rear side of the baffle 4, and a right push block 601 is fixedly installed on the right side of the top rear side of the baffle 4. The rear sides of both the left push block 6 and the right push block 601 are matched with the stretchable length of the telescopic block 11 and the thickness of the circular plate 12. The bottom of the left push block 6 is at the same level as the bottom of the circular plate 12 before the telescopic block 11 is stretched, and the top of the right push block 601 is at the same level as the top of the circular plate 12 after the telescopic block 11 is stretched. The right side of the left push block 6 and the left side of the right push block 601 are both provided with inclined surfaces in opposite directions. The upper and lower parts of the telescopic block 11 are connected by a spring-loaded locking mechanism, so that when in use... The telescopic block 11 is connected by a spring-loaded locking mechanism between its upper and lower parts. The upper and lower parts of the telescopic block 11 are locked by a spring-loaded steel ball and a groove. The steel ball can extend and retract when pressed, and is fixed by spring when there is no external force. For example, in the case of a telescopic antenna, when the baffle 4 moves to the rightmost position, the left push block 6 is pushed to the right by the right-side inclined surface, which pushes the circular plate 12 upward, thus stretching the telescopic block 11. When the baffle 4 moves to the leftmost position, the right push block 601 is pushed to the left by the left-side inclined surface, which pushes the circular plate 12 downward, thus retracting the telescopic block 11. Threaded rods 7 are rotatably mounted on both the left and right sides of the front side of the inner cavity of the frame 1. A slider 8 is rotatably mounted on the outer surface of the threaded rod 7. A front cleaning rod 9 is fixedly mounted on the side of the slider 8 away from the threaded rod 7. A rear cleaning rod 10 is provided on the rear side of the filter plate 2. Slide grooves 201 are provided on both the front and rear sides of the filter plate 2. A front magnet 801 is fixedly mounted on the rear side of the slider 8. A rear magnet 1001 is fixedly mounted on the left side of the rear cleaning rod 10. The outer surface shapes of the front magnet 801 and the rear magnet 1001 match the inner cavity shape of the slide groove 201. The magnetic poles of the front magnet 801 and the rear magnet 1001 are opposite on opposite sides. The bottom of the rear cleaning rod 10 is higher than the top of the front cleaning rod 9. A cleaning brush is fixedly mounted on the rear side of the front cleaning rod 9. A cleaning cotton is fixedly installed on the front side of the rear cleaning rod 10. When in use, the front magnet 801 and the rear magnet 1001 are used to make the rear cleaning rod 10 slide on the rear surface of the filter plate 2 through the rear magnet 1001 and the slide groove 201. At the same time, when the slider 8 drives the front magnet 801 to move up and down, the rear magnet 1001 drives the rear cleaning rod 10 to move up and down synchronously. With the position of the rear cleaning rod 10 being higher than that of the front cleaning rod 9, when the cleaning brush on the rear side of the front cleaning rod 9 cleans the front surface of the filter plate 2, it can push the impurities in the filter hole cavity to the rear surface of the filter plate 2. Then, the cleaning cotton on the front side of the rear cleaning rod 10 cleans the rear surface of the filter plate 2. The combination of these two methods improves the cleaning effect on the filter plate 2. A telescopic block 11 is fixedly installed on the top of the threaded rod 7, a circular plate 12 is fixedly installed on the top of the telescopic block 11, a locking block 13 is fixedly installed on the top of the circular plate 12, and motors 14 are fixedly installed on the left and right sides of the top of the frame 1. A gear 15 is detachably installed on the output shaft of the motor 14, and a locking hole 16 is opened at the bottom of the gear 15. An adsorption wheel 18 is provided in the middle of the inner cavity of the frame 1. An adsorption fan 17 is provided in front of the adsorption wheel 18. A burner 19 is provided in the rear of the adsorption wheel 18. A desorption fan 20 is provided in the rear of the burner 19. Collection frames 21 are detachably installed on both the left and right sides of the bottom of the inner cavity of the frame 1. A cover plate 22 is rotatably installed on the top of the collection frame 21 via a torsion shaft. A rubber pad 23 is fixedly installed on the left side of the collection frame 21. Multiple barbs 24 are fixedly installed on the rear side wall of the inner cavity of the collection frame 21. A vertical groove is opened in the middle of the rubber pad 23. The middle of the rubber pad 23 is on the same vertical plane as the middle of the front cleaning rod 9. The rear and left and right sides of the inner cavity of the collection frame 21 are designed with slopes. Therefore, when the front cleaning rod 9 moves down into the inner cavity of the collection frame 21, the vertical groove opened in the middle of the rubber pad 23 is used, and the position of the rubber pad 23 is located in the inner cavity of the frame 1, which facilitates the front cleaning. The left side of rod 9 can be moved down from the vertical groove in the middle of rubber pad 23. At the same time, the part of the front cleaning rod 9 with the cleaning brush fixedly installed squeezes the cover plate 22 into the inner cavity of the collection frame 21. With the help of the barb 24, the impurities generated when cleaning the front surface of the filter plate 2 can be poured into the inner cavity of the collection frame 21 for collection and cleaning of the cleaning brush on the rear side of the front cleaning rod 9, thereby improving cleaning efficiency. At the same time, the waste hole located directly below the rear cleaning rod 10 at the bottom of the inner cavity of the frame 1 is used. Because there are fewer impurities on the rear surface of the filter plate 2, the impurities generated by the cleaning of the rear cleaning rod 10 are collected in the inner cavity of the waste hole directly below. Afterwards, the filter plate 2 can be disassembled regularly for garbage cleaning and the filter plate 2 can also be replaced.
[0017] Working principle: First, assemble all the structures correctly, and then start the formal operation. During operation, the waste gas containing NMP to be treated is transported to the front of the frame 1 and pre-treated by the filter plate 2 to remove dust particles in the waste gas. Then it is transported to the adsorption rotor 18, and after being treated by the adsorption fan 17, the burner 19 and the desorption fan 20, the waste gas is discharged. At the beginning of operation, the left baffle 4 and the right baffle 4 are located on the left and right sides of the frame 1, respectively. During use, the motor 14 can be started and stopped manually or by using a PLC controller to control its start and stop at regular intervals. First, start the left motor 14, causing the gear 15 connected to the bottom of the motor 14 to rotate. This, in conjunction with the meshing gear 5, moves the baffle 4 to the right until it reaches the far right of the inner cavity of the mounting slot 3, at which point it stops moving. At this point, the baffle 4 completely covers the left opening area of the filter plate 2, and the rotation of the gear 15 will not cause the meshing gear 5 and the baffle 4 to continue moving to the right. Simultaneously, the left push block 6 pushes the circular plate 12 upwards. Move the locking block 13 into the inner cavity of the locking hole 16. Here, the cross-sectional shape of the locking block 13 matches that of the locking hole 16 and both are regular polygons. Therefore, during the rotation of the gear 15, the locking block 13 can quickly enter the inner cavity of the locking hole 16. After entering, the rotation of the gear 15 drives the circular plate 12, the telescopic block 11 and the threaded rod 7 to rotate through the locking hole 16 and the locking block 13. This drives the slider 8 to move down at a constant speed. Using the front magnet 801 and the rear magnet 1001, the slider 8 drives the front cleaning rod 9 to move down while simultaneously driving the rear cleaning rod 10 to move down. During the downward movement, the cleaning brush area on the rear side of the front cleaning rod 9 is used to clean the front surface of the filter plate 2 and extend into it to remove impurities from the inner cavity of the opening on the left side of the filter plate 2. The position of the rear cleaning rod 10 is higher than that of the front cleaning rod 9, so the cleaning brush on the front side of the rear cleaning rod 10 can simultaneously clean the rear surface of the filter plate 2 and the impurities removed from the inner cavity of the opening by the cleaning brush. When the front cleaning rod 9 moves to the bottom, the part of the front cleaning rod 9 with the cleaning brush extends into the inner cavity of the collection frame 21, so as to pour the impurities generated during cleaning into the inner cavity of the collection frame 21. With the help of the barb 24, the residual impurities on the surface and inside of the cleaning brush are cleaned when the cleaning brush moves upward, which improves the working efficiency of the cleaning brush during the next cleaning. At the same time, the impurities cleaned by the rear cleaning rod 10 are accumulated in the inner cavity of the waste hole opened directly below. After cleaning, control motor 14 to rotate in the opposite direction. At this time, the meshing tooth 5 drives the baffle 4 to move to the left until the baffle 4 no longer blocks the left opening area of the filter plate 2. During the leftward reset of the baffle 4, the slider 8 moves to the initial position synchronously after the baffle 4 moves to the leftmost position because of the threads on the inner wall of the slider 8 and the surface of the threaded rod 7. Then, the right push block 601 is used to make the circular plate 12 move down. At this time, the locking block 13 moves down and disengages from the locking hole 16. The motor 14 can no longer drive the threaded rod 7 to rotate. Then, the motor 14 is turned off. The above steps only cover the left side opening area of the filter plate 2. The cleaning brush has nylon bristles, and the cleaning cotton is made of polyester fiber. To clean the right side opening of the filter plate 2, simply press to start the right motor 14. During operation, you can press the left or right motor 14 in sequence to clean the filter plate 2 without stopping the machine.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
