Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth bag dust collector, and particularly relates to a cloth bag dust collector for preventing blockage of negative electrode material processing. BACKGROUND

[0002] In the processing of negative electrode materials (such as graphite, silicon-based materials, etc.), a large amount of ultrafine dust is generated in the crushing, screening and conveying links of the materials. Such dust has the characteristics of small particle size (usually less than 10 microns) and strong adhesion, and is extremely easy to adhere to the surface of the dust removal cloth bag and penetrate into the fiber gap, resulting in the following technical bottlenecks of the traditional cloth bag dust collector.

[0003] Most of the existing dust collectors use fixed filter bag structure and rely on manual regular shutdown cleaning. However, for high-viscosity negative electrode material dust, the back-blowing airflow is difficult to completely remove the particles embedded in the deep filter material, resulting in rapid decrease of the filter bag porosity and continuous rise of the equipment resistance.

[0007] Preferably, the top of the dust removal box is provided with an input port, and a dust suction machine is installed on the side wall of the dust removal box, the number of the dust suction machines is two, the two dust suction machines are matched with the first dust removal cavity and the second dust removal cavity respectively, dust suction pipes one and two are installed on the outer walls of the lower parts of the first dust removal cavity and the second dust removal cavity respectively, control valves are installed on the dust suction pipes one and two, and the dust suction pipes one and two are sealingly connected with the input end of the dust collector and are in conduction; when the utility model is used, the dust collector is started to perform air suction through the dust suction pipes one and two, the input port is in the state of air suction, and dust removal treatment is performed through the first dust removal cavity and the second dust removal cavity at this time.

[0008] Preferably, there are two filter bags, which are located inside the first dust removal chamber and the second dust removal chamber, respectively. The first dust removal chamber and the second dust removal chamber have the same internal structure. The two filter bags are located inside the first dust removal chamber and the second dust removal chamber, which facilitates their alternating use.

[0009] Preferably, the bottom of the cleaning screw is fixedly connected to the output end of the forward and reverse motors, and the forward and reverse motors are fixedly installed on the inner bottom wall of the dust collector; a threaded block is threadedly connected to the outer wall of the cleaning screw, a connecting box is fixedly installed on the side wall of the threaded block, the cleaning plate is installed on the outer wall of the connecting box, and the driving block is installed at one end of the threaded block; in use, by starting the forward and reverse motors, the cleaning screw drives the threaded block to move, which simultaneously drives the cleaning plate and the driving block to move, thereby realizing the cleaning plate cleaning the filter bag.

[0010] Preferably, a cleaning shaft is slidably connected to the inner wall of the cleaning plate, and a cleaning spring is fixedly installed on the outer wall of the cleaning shaft. The other end of the cleaning spring is fixedly connected to the inner wall of the cleaning plate. A drive shaft is rotatably connected inside the cleaning plate. An eccentric wheel is fixedly installed on the upper outer wall of the drive shaft, and the eccentric wheel matches one end of the cleaning shaft. A vibrating plate is fixedly installed on the other end of the cleaning shaft, and the vibrating plate matches the cloth bag. The outer wall at the bottom of the drive shaft is driven by a transmission belt to the cleaning screw. When the cleaning screw rotates, causing the cleaning plate to move upward, the cleaning plate will press against the cloth bag, causing the cloth bag to move upward. When the bag is flipped over, with the inner side of the bag facing outwards, the collected impurities are located on the outside of the bag. Driven by the transmission belt, the drive shaft rotates the eccentric wheel, which then abuts against the cleaning shaft on the inner wall of the cleaning plate. This causes the cleaning shaft to slide outwards, driving the vibrating plate to reciprocate and circulate the inside of the bag. Impurities on the outside of the bag are detached, achieving a tapping and vibration effect on the outside of the bag, preventing impurities from adsorbing, ensuring cleaning effectiveness, and avoiding clogging. This achieves an automatic cleaning function. Afterwards, a vacuum cleaner collects the impurities on the outer wall of the bag for further filtration. This device achieves a linkage effect between vibration and cleaning flipping.

[0011] Preferably, a connecting shaft is rotatably connected inside the connecting box, and the top of the connecting shaft is driven to the driving shaft via a transmission belt; a drive shaft is rotatably connected inside the driving block, and the bottom of the drive shaft is driven to the connecting shaft via a drive belt; a drive gear is fixedly installed on the top of the drive shaft, and a release plate is provided on the outer wall of the drive shaft.

[0012] Preferably, a cleaning gear is fixedly installed on the outer wall of the top of the cleaning screw; a drive rod is rotatably connected inside the control box, and a slide cylinder is slidably connected to the upper limit of the outer wall of the drive rod. The bottom of the slide cylinder matches the release plate. A rotating gear is installed on the outer wall of the slide cylinder via a one-way bearing. The rotating gear matches the cleaning gear and the driving gear. A fixed plate is fixedly installed on the top of the slide cylinder, and a compression spring is fixedly installed on the bottom of the fixed plate. The other end of the compression spring is connected to the top of the slide cylinder. A worm gear is installed on the outer wall of the bottom of the drive rod. The other end of the spiral spring is fixedly connected to the inner bottom wall of the control box. In the initial state of the device, the rotating gear and the cleaning gear are meshed. When the first dust removal chamber needs to be cleaned, the forward and reverse motor inside the first dust removal chamber is started, causing the forward and reverse motor to rotate forward. At the same time, the control valve on the outer wall of the suction pipe is closed, enabling the second dust removal chamber to remove dust. At this time, when the cleaning screw rotates forward, it will drive the rotating gear to rotate through the cleaning gear. At this time, the slide cylinder drives the drive rod to rotate, and the spiral spring is in a compressed state. When the cleaning screw continues to rotate, it will cause the threads on its outer wall to rotate. The drive block engages with the rotating gear. As the drive block moves upward, the release plate on its outer wall abuts against the bottom of the slide cylinder, causing the slide cylinder to gradually move upward. This engages the gear with the rotating gear, causing the cleaning plate to flip the cloth bag over. Then, the rotating gear disengages from the cleaning gear, the forward and reverse motors stop rotating forward, and the vacuum cleaner begins to suck up dust. Simultaneously, under the action of the worm spring, the drive rod drives the shaft to rotate, and under the action of the drive belt and transmission belt, the eccentric wheel rotates, achieving an automatic cleaning effect. After cleaning, the forward and reverse motors reverse, resetting the device. This device utilizes… Under the action of the lead screw, the drive rod can be driven to rotate synchronously. After rotation, the drive rod can automatically drive the cleaning plate to clean, realizing the linkage function. At the same time, when cleaning is needed, the device only needs to start the forward and reverse motors to drive the cleaning plate to move upward and automatically clean it. After cleaning, it can automatically reset, which is convenient for repeated dust suction and filtration, and can avoid the clogging of the filter bag. The cleaning plate of this device can automatically connect with the drive rod to avoid energy waste and prevent cleaning when it is not needed or when it is not completely sealed.

[0013] Preferably, a linkage shaft is rotatably connected to the side wall of the fixed plate, and the linkage shaft is fixedly connected to the top of the cleaning screw.

[0014] Preferably, a linkage bevel gear is fixedly installed on the outer wall of the top of the linkage shaft. The linkage bevel gear meshes with the connecting bevel gear. The connecting bevel gear is installed on the outer wall of one end of the connecting screw. The connecting screw is rotatably connected to the inner wall of the fixed plate. A sealing plate is fixedly installed inside the fixed plate. A sliding plate is slidably connected inside the sealing plate. The sliding plate is threadedly connected to the outer wall of the connecting screw. When cleaning is required, the rotation of the cleaning screw can synchronously drive the connecting screw to rotate under the action of the two bevel gears, thereby realizing the sliding of the sliding plate. This allows the sliding plate to seal the top of the cavity, achieving an overall seal of the cavity. This avoids the phenomenon of cleaning the filter bag when removing dust from the negative electrode material. This device can avoid simultaneous cleaning and dust removal, ensuring the linkage and sealing effect of the device.

[0015] The beneficial effects of this invention are as follows: 1. This device, with its first and second dust removal chambers, enables dual cleaning and dust removal. It allows for alternating use of the dust removal chambers when needed, achieving dust removal without stopping the machine. After long-term use, to prevent bag clogging, the device features an automatic cleaning plate. A fixing plate seals one dust removal chamber, allowing for cleaning while the other performs dust removal. This dual-chamber system ensures simultaneous cleaning and dust removal, maintaining the device's normal dust removal efficiency. The first and second dust removal chambers guarantee a clean production environment and ensure continuous dust removal operations. When dust removal is required, the two chambers work alternately, completing the task without stopping the machine, thus significantly improving production efficiency and reducing time and economic losses due to downtime maintenance.

[0016] 2. The cleaning axis slides outward, driving the vibrating plate to reciprocate and circulate the inside of the bag. Impurities on the outside of the bag can be removed from the bag. This knocking and vibration of the outside of the bag prevents the adsorption of impurities, ensures the cleaning effect, and avoids clogging, thus achieving an automatic cleaning function. Then, a vacuum cleaner collects the impurities on the outer wall of the bag, which is convenient for the bag to filter again. This makes the vibration and cleaning flipping of the device work together.

[0017] 3. This device, through the action of the lead screw, can synchronously drive the drive rod to rotate. After rotation, the drive rod can automatically drive the cleaning plate to clean, realizing a linkage function. At the same time, when cleaning is needed, simply start the forward and reverse motors to drive the cleaning plate to move upward and automatically clean it. After cleaning, it can automatically reset, facilitating repeated dust suction and filtration, and preventing the filter bag from clogging. The cleaning plate of this device can automatically connect with the drive rod to avoid energy waste and prevent cleaning from happening when cleaning is not needed or when the seal is not complete.

[0018] 4. When cleaning is required, the rotation of the cleaning screw in this device can simultaneously drive the connecting screw to rotate under the action of the two bevel teeth, thereby enabling the sliding plate to slide and seal the top of the cavity, achieving an overall seal of the cavity. This avoids the phenomenon of cleaning the filter bag while removing dust from the negative electrode material. This device can avoid cleaning and dust removal from happening simultaneously, ensuring the linkage and sealing effect of the device. Attached Figure Description

Figures 1-2As shown, a dust collector 1 is divided into a first dust collector chamber 3 and a second dust collector chamber 4 by a partition 10. Each of the first and second dust collector chambers 3 and 4 contains a filter bag 5. A cleaning plate 6 is slidably connected inside the dust collector 1 and is located below the filter bags 5. A drive assembly consists of a cleaning screw 7 and a drive block 8. The cleaning screw 7 is drivenly connected to the cleaning plate 6 and rotatably connected to the inner wall of the dust collector 1. The drive block 8 is drivenly connected to the outer wall of the cleaning screw 7. A dust collector plate 501 is fixedly installed inside the dust collector 1, and the filter bags 5 are installed on the outer wall of the dust collector plate 501. A control box 9 is installed on one side below the dust collector plate 501 and is drivenly connected to the cleaning screw 7. The control box 9 is matched with the drive block 8. A fixing plate 2 is located at the upper part of the dust collector 1 and seals the first and second dust collector chambers 3 and 4. This device uses the first... The setup of the first dust removal chamber 3 and the second dust removal chamber 4 enables dual cleaning and dust removal. They can be used alternately when dust removal is needed, achieving dust removal without stopping the machine. After long-term use, to prevent clogging of the filter bag 5, the cleaning plate 6 enables automatic cleaning when cleaning is required. One dust removal chamber is sealed by the fixing plate 2, and the sealed chamber is cleaned while the other is used for dust removal. This allows the two dust removal chambers to perform dust removal and cleaning simultaneously, with the two chambers used alternately without affecting the normal dust removal effect. The first dust removal chamber 3 and the second dust removal chamber 4 ensure the cleanliness of the production environment and achieve continuous dust removal operations. When dust removal is needed, the two chambers can work alternately, completing the dust removal task without stopping the machine, thereby greatly improving production efficiency and reducing the time and economic losses caused by downtime maintenance.

[0023] As attached Figure 1 As shown, the top of the dust collection box 1 is provided with an inlet 101, and two vacuum cleaners 102 are installed on the side wall of the dust collection box 1. The two vacuum cleaners 102 are matched with the first dust collection chamber 3 and the second dust collection chamber 4 respectively. The lower outer walls of the first dust collection chamber 3 and the second dust collection chamber 4 are respectively equipped with a first suction pipe 103 and a second suction pipe 104. Control valves 106 are installed on the first suction pipe 103 and the second suction pipe 104. The first suction pipe 103 and the second suction pipe 104 are sealed and connected to the input end of the dust collector 105. When the device is in use, by starting the dust collector 105, the dust collector 105 will draw air through the first suction pipe 103 and the second suction pipe 104. The inlet 101 is in the state of drawing air. At this time, the dust is removed through the first dust collection chamber 3 and the second dust collection chamber 4.

[0024] As attached Figure 2As shown, the filter bag 5 is installed on the outer wall of the dust removal plate 501. There are two filter bags 5, which are located inside the first dust removal chamber 3 and the second dust removal chamber 4, respectively. The structures inside the first dust removal chamber 3 and the second dust removal chamber 4 are the same. The two filter bags 5 are located inside the first dust removal chamber 3 and the second dust removal chamber 4, respectively, which can facilitate their alternating use.

[0025] As attached Figures 2-3 As shown, the bottom of the cleaning screw 7 is fixedly connected to the output end of the forward and reverse motor 701, which is fixedly installed on the inner bottom wall of the dust collector 1. A threaded block 702 is threadedly connected to the outer wall of the cleaning screw 7, and a connecting box 703 is fixedly installed on the side wall of the threaded block 702. The cleaning plate 6 is installed on the outer wall of the connecting box 703, and the drive block 8 is installed at one end of the threaded block 702. In use, by starting the forward and reverse motor 701, the cleaning screw 7 drives the threaded block 702 to move, which simultaneously drives the cleaning plate 6 and the drive block 8 to move, thereby realizing the cleaning plate 6 cleaning the filter bag 5.

[0026] As attached Figures 2-4 As shown, a cleaning shaft 601 is slidably connected to the inner wall of the cleaning plate 6, and a cleaning spring 602 is fixedly installed on the outer wall of the cleaning shaft 601.

An eccentric wheel 604 is fixedly installed on the outer wall of the upper part of the drive shaft 603. The eccentric wheel 604 matches one end of the cleaning shaft 601, and a vibrating plate 605 is fixedly installed on the other end of the cleaning shaft 601. The vibrating plate 605 matches the cloth bag 5. The outer wall of the bottom of the drive shaft 603 is driven by the cleaning screw 7 through a transmission belt 606. When the cleaning screw 7 rotates and drives the cleaning plate 6 to move upward, the cleaning plate 6 will press against the cloth bag 5, causing the cloth bag to flip upward. With the inner surface of bag 5 facing outwards, the collected impurities are located on the outside of bag 5. Driven by the transmission belt 606, the drive shaft 603 drives the eccentric wheel 604 to rotate. At this time, the eccentric wheel 604 will abut against the cleaning shaft 601 on the inner wall of the cleaning plate 6, causing the cleaning shaft 601 to slide outwards. This drives the vibrating plate 605 to perform reciprocating cyclic vibration on the inside of bag 5, allowing impurities on the outside of bag 5 to detach from bag 5. This vibration and tapping action on the outside of bag prevents impurities from adsorbing, ensuring cleaning effectiveness and avoiding blockage, thus achieving automatic cleaning. Then, the vacuum cleaner 102 collects the impurities on the outer wall of bag 5, facilitating the re-filtration of bag 5. This allows the vibration and cleaning / turning of the device to achieve a linkage effect.

[0027] As attached Figure 5As shown, a connecting shaft 704 is rotatably connected inside the connecting box 703, and the top of the connecting shaft 704 is driven to the drive shaft 603 via a transmission belt 606; a drive shaft 801 is rotatably connected inside the drive block 8, and the bottom of the drive shaft 801 is driven to the connecting shaft 704 via a drive belt 802; a drive gear 803 is fixedly installed on the top of the drive shaft 801, and a release plate 804 is provided on the outer wall of the drive shaft 801.

The other end of the spring 906 is fixedly connected to the inner bottom wall of the control box 9. In the initial state of this device, the rotating gear 903 and the cleaning gear 705 are meshed. When the first dust removal chamber 3 needs to be cleaned, the forward and reverse motor 701 inside the first dust removal chamber 3 is started, causing the forward and reverse motor 701 to rotate forward. At the same time, the control valve 106 on the outer wall of the suction pipe 103 is closed, so that the second dust removal chamber 4 can be cleaned. At this time, when the cleaning screw 7 rotates forward, it will drive the rotating gear 903 to rotate through the cleaning gear 705. At this time, the slide cylinder 902 drives the drive rod 901 to rotate, and the worm spring 906 is in a compressed state. When the cleaning screw 7 continues to rotate, it will cause the threaded block 70 on its outer wall to be threaded. 2. The drive block 8 engages with the rotating gear 903. As the drive block 8 moves upward, the release plate 804 on its outer wall abuts against the bottom of the slide cylinder 902, causing the slide cylinder 902 to gradually move upward. This engages the gear 803 with the rotating gear 903, causing the cleaning plate 6 to flip the cloth bag 5. Then, the rotating gear 903 disengages from the cleaning gear 705, the forward and reverse motor 701 stops rotating forward, and the vacuum cleaner 102 begins to suck up dust. Simultaneously, under the action of the worm spring 906, the drive rod 901 drives the drive shaft 801 to rotate. At the same time, under the action of the drive belt 802 and the transmission belt 606, the eccentric wheel 604 rotates, achieving an automatic cleaning effect. After cleaning, the forward and reverse motors... Motor 701 reverses to achieve reset; under the action of the cleaning screw 7, this device can synchronously drive the drive rod 901 to rotate. After rotation, the drive rod 901 can automatically drive the cleaning plate 6 to clean, realizing the linkage function.
