Abstract
Description
Technical Field
[0001] This utility model relates to the field of grain processing technology, specifically to a vibrating bag filter dust collector for grain processing. Background Technology
[0002] In the critical stages of grain processing, such as screening, grinding, and conveying, a large amount of dust is inevitably generated. Impurities in this dust, such as soil, sand, microorganisms, and pesticide residues, easily adhere to the surface of the cloth bags used to load the grain and penetrate into the grain itself. If not removed promptly, this not only reduces the purity of the grain but also significantly affects its quality and taste, causing serious damage to product quality.
[0003] Existing baghouse dust collectors for grain processing mainly rely on mechanical vibration or manual bag turning and beating for cleaning. Mechanical vibration suffers from uneven impact force distribution and insufficient penetration depth, making it difficult to effectively remove fine dust embedded deep within the bag's fiber structure. Manual beating is not only inefficient and labor-intensive, but its cleaning effect is also significantly affected by human factors. Furthermore, complex structures such as bag folds and seams easily create dust collection dead zones. Long-term dust accumulation reduces the bag's air permeability and increases filtration resistance, significantly reducing dust collection efficiency, severely shortening the bag's lifespan, and increasing equipment operation and maintenance costs.
[0004] Therefore, the applicant proposes a vibrating bag filter dust collector for grain processing. Utility Model Content

[0028] In the field of grain processing technology, traditional vibrating baghouse dust collectors suffer from low dust removal efficiency and poor quality. This not only leads to a dust-filled production environment, seriously threatening the health of workers and significantly increasing the risk of occupational diseases such as pneumoconiosis, but also causes dust to adhere to and contaminate the grain, affecting the quality of the finished product. This utility model addresses the problems of low efficiency and poor quality in traditional grain processing baghouse dust collectors by achieving highly efficient dust removal through a series of innovative designs. The specific implementation method is as follows:
[0029] like Figures 1-3 As shown, a vibrating bag filter dust collector for grain processing includes a base plate 1. A sliding groove is formed at the upper end of the base plate 1. A sliding assembly 2 is disposed inside the sliding groove at the upper end of the base plate 1. The sliding assembly 2 includes first sliders 21 symmetrically slidably disposed within the sliding groove at the upper end of the base plate 1. A support plate 3 is fixedly disposed at the upper end of the two first sliders 21, and the support plate 3 is perpendicular to the base plate 1. A mounting plate 4 is fixedly disposed in the middle of the base plate 1. Multiple second sliders 5 are symmetrically slidably disposed within a sliding groove on one side of the mounting plate 4. The second sliders 5 are driven by a servo motor driving a lead screw located in the sliding groove at the bottom of the mounting plate 4, thereby causing the second sliders 5 threadedly connected to the lead screw to reciprocate. The sliding groove limits the movement of the second sliders 5, so that under the drive of the servo motor, the two second sliders 5 move along the sliding groove. The groove moves back and forth. One end of one of the second sliders 5 is provided with a vibration component 6. The vibration component 6 includes a connecting rod 61 fixedly installed at one end of the second slider 5. One end of the connecting rod 61 is provided with a connecting plate 62. The connecting plate 62 is perpendicular to the mounting plate 4, and the length of the connecting plate 62 is slightly less than the width of the two support plates 3. The upper end of the connecting plate 62 is symmetrically fixedly provided with a first spring 63. The upper ends of the two first springs 63 are fixedly provided with the same top plate 64. The two ends of the top plate 64 are symmetrically fixedly connected with vibration plates 65. The vibration plates 65 are made of rubber and have good elasticity and flexibility. They can effectively buffer vibration and reduce the impact on the cloth bag. The inside of one end of the connecting rod 61 is fixedly provided with a drive motor 66. The output shaft of the drive motor 66 is fixedly provided with a cam 67.
[0030] When the drive motor 66 drives the cam 67 to rotate, the cam 67 gradually lifts the top plate 64 as its contour curve changes. During this process, the top plate 64 is pushed upward by the cam 67, overcoming the elastic force of the first springs 63 at both ends and moving upward, thus stretching the first springs 63. As the cam 67 continues to rotate, the contact point between the cam 67 contour curve and the top plate 64 changes, and the push force of the cam 67 on the top plate 64 gradually decreases. At this time, the stretched first springs 63 begin to release their elastic potential energy, generating a downward restoring force, which drives the top plate 64 to move downward. As the cam 67 continues to rotate, this lifting and lowering process is repeated continuously, causing the vibrating plate 65 to perform high-frequency reciprocating motion in the vertical direction, thereby causing the vibrating plate 65 to continuously vibrate on the inner wall of the bag, gradually shaking off the dust.
[0031] The servo motor drives the lead screw to move the second slider 5, which is threadedly connected to the lead screw, back and forth. This allows the top plate 64 to move up and down back and forth, continuously vibrating and screening all corners of the filter bag, gradually shaking off the dust, reducing vibration dead angles, and improving dust removal quality.
[0032] A fixing rod 71 is fixedly installed at one end of another second slider 5, and a vacuum cleaner 72 is fixedly installed at the end of the fixing rod 71 away from the second slider 5. A vacuum cleaner tube 73 is fixedly installed at the upper end of the vacuum cleaner 72.
[0033] When the top plate 64 shakes off the dust, the dust particles detach from the surface of the cloth bag due to inertia and become suspended in the air. At this time, the motor inside the vacuum cleaner 72 drives the impeller to rotate at high speed, creating a negative pressure environment inside the suction chamber. The pressure difference between the outside atmospheric pressure and the suction chamber causes air to flow rapidly into the suction pipe 73. The multiple through holes at the upper end of the suction pipe 73 expand the suction range, allowing the suspended dust to be sucked into the pipe under the airflow. The vacuum cleaner 72 is positioned directly below the top plate 64, using gravity to assist the dust to fall, combined with the negative pressure suction, to form a dual dust removal effect, effectively preventing dust from being re-entrained and improving dust removal efficiency.
[0034] like Figure 4 As shown, cleaning units are symmetrically arranged at both ends of the second slider 5. Each cleaning unit includes a connecting block 81 symmetrically fixed at one end of the second slider 5. A horizontal plate 82 is fixedly arranged at one end of the connecting block 81. Multiple sliding rods 83 are slidably arranged inside the horizontal plate 82. One end of the multiple sliding rods 83 is connected to the same cleaning plate 84. Multiple sets of brushes 85 are arranged in an array at one end of the cleaning plate 84. A limit block is fixedly arranged at the end of the sliding rod 83 away from the cleaning plate 84. The limit block prevents the sliding rod 83 from sliding out of the cleaning plate 84. A second spring 86 is sleeved on the sliding rod 83 and fixed between the limit block and the connecting block 81.
[0035] The second spring 86 drives the sliding rod 83 forward, thereby driving the brush 85 to clean the inner wall of the bag. The maximum extension length of the brush 85 matches the length of the top plate 64 and the width of the two support plates 3, which ensures that the brush 85 can cover the area reached by the vibration of the top plate 64 to clean the inner wall of the bag, while mechanical limiting prevents the brush 85 from exerting excessive pressure on the bag and protects the bag from mechanical damage.
[0036] like Figure 5 As shown, each of the two support plates 3 has a sliding groove 31 on one side wall. A sliding block 91 is slidably arranged inside the sliding groove 31. A third spring 92 is fixedly arranged between the sliding block 91 and the bottom of the sliding groove 31. A locking plate 93 is fixedly arranged at one end of the sliding block 91. A moving rod 94 is slidably arranged at the upper end of the locking plate 93. A chuck 95 is fixedly arranged at the lower end of the moving rod 94. A fourth spring 96 is sleeved on the moving rod 94 and fixed between the locking plate 93 and the chuck 95.
[0037] The slide 31 has a slot on its side wall, and a locking block 97 is engaged inside the slot. Both locking blocks 97 are fixedly connected to the two sides of the sliding block 91. The locking blocks 97 prevent the sliding block 91 from shifting laterally during the up and down sliding process and limit the sliding block 91 laterally.
[0038] By moving the moving rod 94 upward, the chuck 95 moves upward, squeezing the fourth spring 96, and inserting the opening of the grain processing bag through the through hole of the clamping plate 93, clamping it inside the clamping plate 93. Releasing the moving rod 94 releases the elastic potential energy of the fourth spring 96, which in turn drives the chuck 95 to clamp and fix the bag. At the same time, the third spring 92 drives the sliding block 91 downward, thereby fully opening the bag to avoid wrinkles that would lead to poor dust removal effect. The third spring 92 has a smaller elastic force to avoid a larger restoring force that would damage the bag.
[0039] like Figure 6 As shown, the sliding assembly 2 includes a rotating rod 22 rotatably connected inside one side of the base plate 1. One end of the rotating rod 22 is provided with a rotating disk 23, and the other end of the rotating rod 22 is fixedly connected with a worm gear 24. The lower end of the worm gear 24 is engaged with a turbine 25, and the middle part of the turbine 25 is provided with a lead screw 26. The lead screw 26 is threadedly connected to two first sliders 21, and both ends of the lead screw 26 are rotatably connected to the base plate 1.
[0040] Rotating the rotating disk 23 drives the worm gear 24 to rotate, which in turn drives the turbine 25 meshing with the worm gear 24 to rotate. The turbine 25 drives the lead screw 26 to rotate. The distance between the two symmetrical first sliders 21 is adjusted according to the actual size of the grain processing bag to ensure that the bag is opened in both directions, avoid wrinkles that may cause dust removal dead angles, and improve the adaptability of the dust removal device.
[0041] The two support plates 3 are symmetrical about the center of the base plate 1, and the center lines of the two support plates 3 and the mounting plate 4 are on the same straight line, ensuring that the grain processing cloth bag is clamped tightly without deflection and damage during the dust removal process.
[0042] In summary, when using a vibrating bag filter for grain processing, the rotating disk 23 drives the worm gear 24 to rotate, adjusting the two symmetrical support plates 3 to a suitable position to ensure the bag is stretched open in both directions, avoiding wrinkles and dust-collecting dead angles. The drive motor 66 drives the cam 67 to rotate, causing the vibrating plate 65 to perform high-frequency reciprocating motion in the vertical direction. This causes the vibrating plate 65 to vibrate continuously on the inner wall of the bag, gradually shaking off the dust. The second slider 5 drives multiple sets of brushes 85 at one end of the cleaning plate 84 to clean the inner wall of the grain processing bag. The dust from the vibration and cleaning is collected by the vacuum cleaner 72 at one end of the second slider 5. The dust falls with the help of gravity, combined with negative pressure suction, forming a dual dust removal effect, effectively preventing secondary dust re-entrainment and improving dust removal efficiency. This dust removal method, which combines mechanical vibration with brush cleaning 85, achieves all-round cleaning of the grain processing bag, effectively improving the overall dust removal effect and work efficiency.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
