Description
Technical Field
[0001] This invention relates to the field of dust removal technology in cat litter production, specifically to an electrostatic pulse dust removal device and method based on cat litter production. Background Technology
[0002] As a daily necessity for pet-owning families, the production scale of cat litter has continued to expand along with the booming development of the pet economy. Currently, the main processes in cat litter production include raw material crushing, ingredient mixing, granulation, drying, screening, and packaging. Among these processes, crushing, screening, and material conveying generate a large amount of dust. This dust mainly comes from bentonite mineral powder, plant fiber microparticles, and additive powders, with a wide particle size distribution, containing a large amount of inhalable fine particulate matter.
[0003] Existing cat litter production lines generally use baghouse dust collectors or pulse-jet baghouse dust collectors to treat exhaust gas at dust-generating points. For example, dust collection hoods are installed in sections such as feeding, mixing, screening, and packaging to collect dust, which is then treated by the dust collector and discharged in an organized manner through exhaust stacks. However, this type of end-of-pipe treatment method has inherent limitations: baghouse dust collectors have limited efficiency in capturing fine dust, filter bags are prone to clogging, and operating resistance is high.
[0004] It is worth noting that in the conveying process of a cat litter production line, there are numerous instances of free-falling materials, such as unloading at the end of belt conveyors, discharging from vibrating screens, and feeding through chutes. During these processes, as cat litter particles fall under gravity, friction and collisions between the particles generate dust, which can easily spread into the workshop environment with the airflow. Existing dust removal solutions mostly employ passive capture using enclosed hoods or gas collection hoods, but the capture efficiency is difficult to guarantee due to limitations in hood opening distance and airflow organization. Summary of the Invention

[0015] Preferably, S1: The device is placed at the litter drop point, and the mounting bracket is fixed on the lower litter conveyor belt bracket, so that the litter falls onto the dust collection belt and falls between the dust collection belt and the cross-flow fan casing; S2: Start the device. The cross-flow fan blows cat litter through the casing, causing dust in the cat litter and the surrounding air to move toward the dust collection belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1.

The device also has the ability to automatically adjust the adsorption force of the pulse electrostatic plate and the tilt angle of the pulse electrostatic plate according to the actual situation such as the size of cat litter particles and the falling speed, which increases the functionality and adaptability of the device during use. 2. This invention uses wind grading, electrostatic adsorption, and gravitational vibration to adsorb fine dust onto the dust collection belt. Under the action of wind, the pulse electrostatic plate itself can capture dust in the surrounding air, further reducing the possibility of fine dust escaping. The dust collection belt has self-cleaning ability, and the self-cleaning part is not located on the adsorption surface, so the cleaning process does not affect the normal adsorption process, increasing the stability of the equipment during use.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figures 1-9The present invention provides a technical solution: an electrostatic pulse dust removal device and method based on cat litter production, including a mounting bracket 1, a pulse electrostatic plate 2 movably mounted on the mounting bracket 1, a dust collection belt 3 movably mounted on the pulse electrostatic plate 2, a cross-flow fan housing 4 on one side of the pulse electrostatic plate 2, and a cross-flow fan 5 rotatably mounted inside the cross-flow fan housing 4. The self-cleaning mechanism 6 includes a first fixed side plate 601, a spiral conveyor roller 602, and a guide roller 608. Two sets of first fixed side plates 601 are fixedly installed on the upper side of the pulse electrostatic plate 2. The spiral conveyor roller 602 is rotatably installed between the two sets of first fixed side plates 601. The guide roller 608 is fixedly installed between the two sets of first fixed side plates 601. The dust collection belt 3 is in contact with the spiral conveyor roller 602 and the guide roller 608. Adjustment mechanism 7 includes hinge rods 704. Two sets of hinge rods 704 are movably mounted on the mounting bracket 1. One end of the hinge rods 704 is set on the pulse electrostatic plate 2. The transmission mechanism 8 includes a connecting hollow rod 805, a first transmission rod 806, and a drive wheel 811. Two sets of connecting hollow rods 805 are fixedly installed between the cross-flow fan housing 4 and the mounting bracket 1. The first transmission rod 806 is installed on the rotating shaft of the cross-flow fan 5. The drive wheel 811 is rotatably installed on the upper and lower sides of the pulse electrostatic plate 2. The dust collection belt 3 is sleeved on the drive wheel 811. One end of the first transmission rod 806 is set on the drive wheel 811. This equipment utilizes the natural fall of cat litter during transportation. Through a combination of gravity oscillation, electrostatic adsorption, and wind grading, fine dust in the cat litter can be separated and collected. This process eliminates the need for additional dust removal steps in the cat litter production process. This process can significantly reduce air pollution generated during cat litter transportation and increase the convenience of equipment use. The equipment itself also has the ability to self-clean and adjust in real time according to the actual adsorption situation, increasing the functionality and adaptability of the equipment.
[0021] Furthermore, the self-cleaning mechanism 6 also includes a dust inlet 603, a connecting cylinder 604, and a dust collection box 605. A dust inlet 603 is provided on a set of first fixed side plates 601. A connecting cylinder 604 is fixedly installed at one end of the dust inlet 603. One end of the spiral conveying roller 602 is rotatably installed inside the connecting cylinder 604. The connecting cylinder 604 and the dust collection box 605 are connected. This structure is the dust removal structure of the dust collection belt 3. The pulse electrostatic plate 2 is used to attract dust in the air when cat litter falls. The dust will adhere to the dust collection belt 3. The dust collection belt 3 can move. When it moves to the spiral conveying roller 602, through contact with the spiral conveying roller 602 and the rotation of the spiral conveying roller 602 itself, the dust attached to the dust collection belt 3 is transported into the dust inlet 603 and enters the dust collection box 605, realizing automated cleaning of dust. Under this structure, neither dust nor the cleaning process will affect the normal operation of the pulse electrostatic plate 2, and continuous cleaning will not reduce the dust attraction of the pulse electrostatic plate 2. Furthermore, the self-cleaning mechanism 6 also includes a dust guide groove 606 and a threaded plug 607. The dust collection box 605 has a dust guide groove 606 inside. One end of the dust guide groove 606 is higher than the other end. The higher end of the dust guide groove 606 is connected to the connecting cylinder 604, while the other end is threaded with a threaded plug 607. The dust collection box 605 is located on the lower side of the spiral conveying roller 602 and is fixedly installed on the mounting frame of the pulse electrostatic plate 2. The outer side of the pulse electrostatic plate 2 is provided with a mounting frame for connection with other structures, such as the fixing of the dust collection box 605 and the fixing of the first fixed side plate 601. This is a mature existing technology and will not be described in detail here. Under the guidance of the shape of the dust guide groove 606, the dust inside the dust collection box 605 will be concentrated near the threaded plug 607, making it easy for the dust to be discharged during cleaning and preventing the dust from being flushed out. This increases the convenience and stability of the equipment during use. Due to the presence of the spiral conveyor roller 602 and the guide roller 608, there will be a certain gap between the dust collection belt 3 and the lower side of the pulse electrostatic plate 2. This gap is the installation space of the dust collection box 605, which helps to save the space occupied by the equipment. Furthermore, the self-cleaning mechanism 6 also includes a dust-blocking block 609 and a rubber dust-removing sheet 610. The dust-blocking block 609 is fixedly installed between the first fixed side plates 601, and the rubber dust-removing sheet 610 is fixedly installed on the dust-blocking block 609. The rubber dust-removing sheet 610 is in contact with the surface of the dust-retaining belt 3. The spiral conveyor roller 602 is located below the guide roller 608, and the rubber dust-removing sheet 610 is located between the spiral conveyor roller 602 and the guide roller 608. The spiral conveyor roller 602 can transport dust by its own rotation, while any dust that may come into contact with the dust is blocked by the contact between the rubber dust-removing sheet 610 and the dust-retaining belt 3. The dust-retaining belt 3 is mounted on the spiral conveyor roller 602 and the guide roller 608 in the shape shown below. Figure 3As shown, under the pressure of the spiral conveyor roller 602, the dust collection belt 3 will naturally form a groove, and the dust blocked by the rubber dust removal sheet 610 will naturally fall into this groove and be conveyed by the spiral conveyor roller 602. The dust blocking block 609 also serves to shield the space on the upper side of the spiral conveyor roller 602, making it less likely for dust to drift upward under the disturbance of the spiral conveyor roller 602, increasing the stability of the equipment during use and the comprehensiveness of cleaning. Furthermore, the self-cleaning mechanism 6 also includes a second fixed side plate 611, a stop block 612, and a pressure sensor 613. The second fixed side plate 611 is fixedly installed on the upper end of the pulse electrostatic plate 2, and the stop block 612 is fixedly installed on the second fixed side plate 611. The stop block 612 is not in contact with the dust collection belt 3. The lower side of the stop block 612 is an inclined surface, and the pressure sensor 613 is fixedly installed on the inclined surface. All components of the pressure sensor 613 are housed within the baffle 612, which is existing technology. The baffle 612 intercepts cat litter. The dust collection belt 3 moves upward, while the cat litter falls downward. Therefore, the cat litter falling on the dust collection belt 3 will stay on the dust collection belt 3 longer because the direction of movement is opposite to that of the dust collection belt 3. This allows the dust to be further attracted by the pulse electrostatic plate 2. However, if the adsorption force generated by the pulse electrostatic plate 2 is too strong or the tilt angle of the pulse electrostatic plate 2 is too small, it is easy to adsorb some smaller cat litter particles onto the dust collection belt 3 and transport them. At this time, the baffle 612 will prevent the cat litter from entering the spiral conveyor roller 602. If a lot of cat litter is attracted, it means that the adsorption generated by the pulse electrostatic plate 2 is too strong or the tilt angle of the pulse electrostatic plate 2 is too small. The adsorption force and angle need to be automatically adjusted accordingly, realizing automatic adjustment. The pressure sensor 613 is located on the upper side of the inclined surface of the baffle 612, which can effectively prevent some small cat litter particles from accidentally touching it. Furthermore, the adjustment mechanism 7 also includes a telescopic motor 701, a slide groove 702, a slide rod 703, and a fixing block 705. The telescopic motor 701 is fixedly installed on the mounting bracket 1. Two sets of slide grooves 702 are provided on the mounting bracket 1. The slide rod 703 is slidably installed in the slide grooves 702. The output shaft of the telescopic motor 701 is fixedly connected to the slide rod 703. The two ends of the slide rod 703 are rotatably installed with hinge rods 704. Two sets of fixing blocks 705 are fixedly installed on the lower side of the pulse electrostatic plate 2. One end of the hinge rod 704 is rotatably installed on the fixing block 705. The lower end of the pulse electrostatic plate 2 is rotatably installed on the left end of the mounting bracket 1. This structure is an adjustable structure for the tilt angle of the pulse electrostatic plate 2. Through the extension and retraction of the telescopic motor 701 and the sensing of the pressure sensor 613, the angle of the pulse electrostatic plate 2 can be automatically adjusted, increasing the functionality of the equipment. In addition, in actual use, the actual installation of the equipment, the size of the cat litter particles, and the falling height of the cat litter are all different, so the required angle of the pulse electrostatic plate 2 is also different. This structure can also adaptively and actively adjust the angle of the pulse electrostatic plate 2 to adapt to the actual situation. Furthermore, the adjustment mechanism 7 also includes a fixed bracket 706, a threaded sleeve 707, a screw 708, and a damping block 709. The fixed bracket 706 is fixedly installed on the lower side of the mounting bracket 1. A threaded sleeve 707 is fixedly installed at the corner of the fixed bracket 706. A screw 708 is threadedly installed inside the threaded sleeve 707, and a damping block 709 is provided at one end of the screw 708. This structure is the mounting structure for the mounting bracket 1, and is generally set at the junction of the cat litter conveyor belt. It is fixed by the threaded action between the screw 708 and the threaded sleeve 707, and by the damping block 709 pressing against the support of the conveyor belt. This fixing method facilitates the movement and adjustment of the equipment, increasing the convenience of use. Furthermore, the transmission mechanism 8 also includes a drive motor 801, a first gear 802, a ring rack 803, a first connecting column 804, a second connecting column 807, a fixed column 808, a second gear 809, a transmission belt 810, a third gear 812, a third connecting column 813, a second transmission rod 814, and a fourth connecting column 815. The drive motor 801 is fixedly mounted on the lower side of the cross-flow fan housing 4. The first gear 802 is fixedly mounted on the output shaft of the drive motor 801. The ring rack 803 is fixedly mounted at the center of the cross-flow fan 5, meshing with the first gear 802. The first connecting column 804 is fixedly mounted at both ends of the central rotating shaft of the cross-flow fan 5. A first transmission rod 806 is rotatably mounted on the first connecting column 804. A second connecting column 807 is rotatably mounted at one end of the first transmission rod 806. The first connecting column 804, the first transmission rod 806, and the second connecting column 807 are all housed within the connecting hollow rod 805. Fixed posts 808 are fixedly installed at both ends of the lower side of the pulse electrostatic plate 2. The fixed posts 808 are rotatably installed on the mounting bracket 1. The second connecting post 807 is rotatably installed inside the fixed post 808. The second gear 809 is rotatably installed at the corner of the mounting frame of the pulse electrostatic plate 2. The same set of transmission belts 810 are sleeved between the two sets of second gears 809 on the same side. The second connecting post 807 is fixedly connected to the second gear 809 on the lower side. The two sets of second gears 809 on the same end are fixedly installed at both ends of the corresponding drive wheel 811. The third gear 812 is rotatably installed inside the front and rear sides of the mounting frame of the pulse electrostatic plate 2. The third gear 812 meshes with the transmission belt 810. The third connecting post 813 is fixedly installed on the third gear 812. The second transmission rod 814 is rotatably installed on the third connecting post 813. One end of the second transmission rod 814 is rotatably installed on the fourth connecting post 815. The fourth connecting post 815 is fixedly connected to the rotating shaft of the spiral conveyor roller 602. This structure serves as both the drive structure and the wind-leveling structure of the equipment. It features the synchronous operation of the rotation of the cross-flow fan 5, the transmission of the cross-flow fan housing 4, and the rotation of the spiral conveying roller 602. The second transmission rod 814 is mounted off-axis with the third connecting column 813 and the fourth connecting column 815, and the first transmission rod 806 is mounted off-axis with the first connecting column 804 and the second connecting column 807. This is a conventional linkage structure. In this structure, the tilt angle of the air outlet of the cross-flow fan housing 4 is matched with the midpoint tilt angle of the pulse electrostatic plate 2 during its rotation process. This ensures that when the pulse electrostatic plate 2 adjusts its angle, the cross-flow fan housing 4 can also ensure that the dust blown out is within the adsorption range of the pulse electrostatic plate 2. Furthermore, a first filter 9 is fixedly installed at the air outlet of the cross-flow fan housing 4, and a dust baffle 10 is fixedly installed on the cross-flow fan housing 4. The tilt angle of the dust baffle 10 is the same as the tilt angle of the cross-flow fan housing 4. A second filter 11 is fixedly installed at the air inlet slot of the cross-flow fan housing 4. This structure can reduce the possibility of dust and cat litter entering the interior of the cross-flow fan housing 4, and also has a certain ability to prevent cat litter particles from rebounding, increasing the stability of the equipment during use. Furthermore, S1: Place the device at the litter drop point and fix the mounting bracket 1 on the lower litter conveyor belt bracket so that the litter falls onto the dust collection belt 3 and falls between the dust collection belt 3 and the cross-flow fan housing 4. S2: Start the equipment. The cross-flow fan blows the cat litter at 4 points, causing the dust in the cat litter and the surrounding air to move towards the dust collection belt 3. The dust is then adsorbed on the dust collection belt 3. The dust collection belt 3 moves upward, increasing the retention time of the cat litter on the dust collection belt 3 and further improving the efficiency of dust adsorption. S3: The spiral conveyor roller 602 rotates, and the rubber dust removal plate 610 scrapes against the dust on the dust collection belt 3, causing the dust to enter the dust collection box 605 and be collected. After being cleaned, the dust collection belt 3 rotates back to the adsorption surface of the pulse electrostatic plate 2. S4: If the cat litter is adsorbed onto the dust collection belt 3 by the pulse electrostatic plate 2, it will move with the dust collection belt 3 and be intercepted by the block 612 and come into contact with the pressure sensor 613. At this time, the pulse electrostatic plate 2 can be adjusted to reduce the adsorption force, or the telescopic motor 701 can be activated to increase the angle of the pulse electrostatic plate 2 so that the cat litter will not be adsorbed, maintaining the maximum critical point of adsorption force for dust.
[0022] Working Principle: When using this invention, the device is placed at the location where cat litter falls, allowing the litter to land on the dust collection belt 3. The litter then passes through the cross-flow fan housing 4 and the dust collection belt 3 into the lower conveyor belt. The fixing bracket 706 is placed on the support of the lower conveyor belt. The rotating screw 708, through the threaded action between itself and the screw sleeve 707, causes the damping block 709 to abut against the bracket, securing the device. The drive motor 801 is started, and the output shaft of the drive motor 801 rotates, driving the first gear 802 to rotate. Through meshing with the ring rack 803, the cross-flow fan 5 rotates. At this time, the exhaust air from the outlet of the cross-flow fan housing 4 blows the cat litter in a directional direction, causing the dust to move towards the dust collection belt 3. The cross-flow fan 5 rotates... The first connecting column 804 is rotated, which in turn drives the first transmission rod 806 and the second connecting column 807 to rotate. The rotation of the second connecting column 807 drives the second gear 809 and the transmission belt 810 to rotate, causing the drive wheel 811 to rotate. The dust collection belt 3 moves due to friction with the drive wheel 811. When the transmission belt 810 rotates, it drives the third gear 812 to rotate. The second transmission rod 814 and the fourth connecting column 815 drive the spiral conveying roller 602 to rotate. The spiral conveying roller 602 cleans the surface of the cross-flow fan housing 4. Dust enters the dust collection box 605 through the dust inlet trough 603 and the connecting cylinder 604 under the cleaning of the spiral conveying roller 602 and the scraping of the rubber dust removal sheet 610.
[0023] At this time, the falling cat litter will first come into contact with the dust collection belt 3. Some dust will be directly attracted and adsorbed onto the dust collection belt 3 by the pulse electrostatic plate 2. As the dust collection belt 3 moves upward, the cat litter stays on the dust collection belt 3 for a longer time, making the dust adsorbed more thoroughly. During the falling process of the cat litter, the airflow generated at the cross-flow fan housing 4 will cause the fine dust in the cat litter to move towards the dust collection belt 3 and be adsorbed onto the dust collection belt 3. If the adsorption force is too strong or the tilt angle is too small, some cat litter itself may also be adsorbed. When the cat litter encounters the block 612, it will be blocked by it and then contact the pressure sensor 613. After the pressure sensor 613 is contacted, it can control the pulse electrostatic plate 2 and the telescopic motor 701 accordingly, so that the adsorption force of the pulse electrostatic plate 2 is reduced, or the telescopic motor 701 is extended and retracted to adjust the angle of the pulse electrostatic plate 2.
