Description

Technical Field

[0001] This invention relates to the field of calcium hydroxide production, and more particularly to a stacking dust prevention device for calcium hydroxide production. Background Technology

[0002] Calcium hydroxide, commonly known as slaked lime or quicklime, is a common inorganic compound. Because calcium hydroxide is an extremely fine powdery solid, very dry and lightweight, it is easily dispersed into the air when disturbed by any external force. Therefore, a large amount of dust is easily generated in various stages of calcium hydroxide production, storage, transportation and subsequent use.

[0003] However, most current dust control equipment uses air pumps and filter frames to adsorb and collect dust from the air. This is not convenient for cleaning and collecting dust adhering to the product surface. Once the product is disturbed by external forces, a large amount of dust will still be generated. In addition, the filter frames need to be cleaned or replaced regularly, which requires a certain amount of manpower and time, resulting in low dust removal efficiency. Summary of the Invention

[0004] In view of the shortcomings or deficiencies of the prior art, the present invention provides a stacking dust prevention device for calcium hydroxide production, which can more effectively reduce dust pollution, improve the working environment, and clean and collect calcium hydroxide particles attached to the filter frame, thereby improving dust removal efficiency.

[0005] A stacking dust prevention device for calcium hydroxide production includes a fixed frame, a conveying component on the fixed frame, the conveying component being inclined, a support frame fixedly connected to the fixed frame, a tray placed on the support frame, a dust collection mechanism on the support frame, and a dust brushing mechanism on the dust collection mechanism.

[0006] Furthermore, the dust collection mechanism includes a limiting frame, and two limiting frames are fixedly connected to the support frame. The two limiting frames are symmetrically arranged, and a sliding block is slidably connected to each of the two limiting frames. A return spring is connected between the sliding block and the limiting frame. A flow guide box is fixedly connected to each of the two sliding blocks, and a filter frame is fixedly connected inside each of the two flow guide boxes. An air pump is fixedly connected to one end of each flow guide box that is far apart from the other, and the air pump is connected to the flow guide box.

[0007] Furthermore, the dust brushing mechanism includes a servo motor, which is fixedly connected to both of the two flow guide boxes. A rotating shaft is rotatably connected inside each of the two flow guide boxes. One end of the rotating shaft is fixedly connected to the output shaft of the servo motor. Several brush rollers are rotatably connected inside each of the two flow guide boxes. Several brush rollers located on the same flow guide box form a group. A transmission component is connected between the bottom ends of two brush rollers and the bottom ends of the two rotating shafts, respectively. A meshing gear is fixedly connected to the top end of each brush roller. Several meshing gears located on the same group of brush rollers form a group. A toothed belt is fitted between several meshing gears in the same group.

[0008] Furthermore, it also includes a cleaning mechanism, which is mounted on the guide box. The cleaning mechanism includes a reciprocating lead screw, which is fixedly connected to two rotating shafts. Nuts are threaded onto both reciprocating lead screws, and sliding frames are fixedly connected to both nuts. Several cleaning plates are fixedly connected to both sliding frames, each cleaning plate having an arc-shaped surface. Several cleaning plates located on the same sliding frame form a group. Top rods are fixedly connected to both sliding frames and are slidably connected to the guide box. Two fixed rods are fixedly connected to the support frame, and the two fixed rods are symmetrically arranged. Several top plates are fixedly connected to both fixed rods, each top plate having a triangular structure. Several top plates located on the same fixed rod form a group.

[0009] Furthermore, it also includes a recycling mechanism, which is mounted on the sliding frame. The recycling mechanism includes scrapers, and scrapers are fixedly connected to the ends of the two sliding frames that are far apart from each other. The scrapers contact the filter frame, and vibrators are fixedly connected to the two scrapers. Discharge hoppers are fixedly connected to the bottom of the two guide boxes, and the guide boxes are connected to the discharge hoppers. A spiral roller is rotatably connected inside the discharge hopper, and a transmission joint is connected between the spiral roller and the bottom end of the rotating shaft. The transmission joint is located outside the discharge hopper, and a collection bucket is fixedly connected to the discharge hopper, and the discharge hopper is connected to the collection bucket.

[0010] First, the conveyor continuously transfers bagged calcium hydroxide to pallets for stacking. Simultaneously, two air pumps and two servo motors are activated. The air pumps draw the calcium hydroxide dust generated when the bagged calcium hydroxide falls onto the pallets into a guide box. A filter rack filters the calcium hydroxide dust. Since calcium hydroxide particles easily accumulate on both sides of the sealed bags during the bagging process, two sets of brush rollers brush off the calcium hydroxide particles attached to the sealing openings on both sides of the bagged calcium hydroxide on the pallet. At the same time, the brushed-off calcium hydroxide particles are drawn into the guide box by the air pumps. In this way, the dust generated during the stacking of bagged calcium hydroxide and the calcium hydroxide particles attached to the sealing openings on both sides of the bagged calcium hydroxide can be cleaned and collected, thereby more effectively reducing dust pollution and improving the working environment.

[0011] When the servo motor drives the shaft to rotate, the two sets of cleaning plates scrape off the calcium hydroxide particles attached to the two sets of brush rollers. The scraped calcium hydroxide particles are then drawn into the guide box by the air pump. When the sliding frame moves the top rod downward or upward, the top rod will drive the sliding frame, guide box, and brush rollers to move horizontally back and forth. This increases the contact area between the guide box and the calcium hydroxide dust, thus enabling more effective suction of calcium hydroxide dust.

[0012] When the nut drives the sliding frame to move up and down reciprocally, the vibrator drives the scraper to vibrate. The scraper vibrates while moving up and down, and the vibration of the scraper effectively scrapes off the calcium hydroxide particles attached to the filter frame. The spiral roller then transfers the calcium hydroxide particles in the discharge hopper to the collection bucket. In this way, the calcium hydroxide particles attached to the filter frame can be cleaned and collected, thereby reducing the occurrence of calcium hydroxide particles clogging the filter frame and improving work efficiency.

Detailed Implementation

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0026] Example 1 A stacking dust prevention device for calcium hydroxide production, such as Figures 1-11 As shown, it includes a fixed frame 1, a conveying component 2 on the fixed frame 1, the conveying component 2 being inclined, a support frame 3 fixedly connected to the fixed frame 1, a tray 4 placed on the support frame 3, a dust collection mechanism on the support frame 3, and a dust brushing mechanism on the dust collection mechanism.

[0027] The dust collection mechanism includes a limiting frame 51. Two limiting frames 51 are fixedly connected to the support frame 3. The two limiting frames 51 are symmetrically arranged. Each limiting frame 51 is slidably connected to a sliding block 52. A return spring 53 is connected between the sliding block 52 and the limiting frame 51. Each sliding block 52 is fixedly connected to a flow guide box 54. Each flow guide box 54 is fixedly connected to a filter frame 55. Each flow guide box 54 is fixedly connected to an air pump 56 at one end that is far apart from each other. The air pump 56 is connected to the flow guide box 54.

[0028] The dust brushing mechanism includes a servo motor 61, which is fixedly connected to both of the two flow guide boxes 54. A rotating shaft 62 is rotatably connected inside each of the two flow guide boxes 54. One end of the rotating shaft 62 is fixedly connected to the output shaft of the servo motor 61. Several brush rollers 63 are rotatably connected inside each of the two flow guide boxes 54. Several brush rollers 63 located on the same flow guide box 54 form a group. The bottom ends of two brush rollers 63 are respectively connected to the bottom ends of the two rotating shafts 62. A meshing gear 65 is fixedly connected to the top end of each brush roller 63. Several meshing gears 65 located on the same group of brush rollers 63 form a group. A toothed belt 66 is fitted between several meshing gears 65 in the same group.

[0029] First, the conveyor assembly 2 continuously transfers bagged calcium hydroxide to the pallet 4 for stacking. Simultaneously, two air pumps 56 and two servo motors 61 are activated. The air pumps 56 draw the calcium hydroxide dust generated when the bagged calcium hydroxide falls onto the pallet 4 into the guide box 54. The filter frame 55 filters the calcium hydroxide dust. The two servo motors 61 drive two rotating shafts 62 to rotate. The rotation of the two rotating shafts 62 drives two brush rollers 63 to rotate via two transmission assemblies 64. The rotation of the two brush rollers 63 drives two meshing gears 65 to rotate. The rotation of the two meshing gears 65 further... The two toothed belts 66 rotate, causing the two sets of meshing gears 65 and the two sets of brush rollers 63 to rotate. Since calcium hydroxide particles easily accumulate on both sides of the sealed bag during the bagging process, the two sets of brush rollers 63 will brush off the calcium hydroxide particles attached to the sealing openings on both sides of the bagged calcium hydroxide on the tray 4. At the same time, the brushed-off calcium hydroxide particles will be drawn into the guide box 54 by the air pump 56. In this way, the dust generated by calcium hydroxide during the stacking of bagged calcium hydroxide and the calcium hydroxide particles attached to the sealing openings on both sides of the bagged calcium hydroxide can be cleaned and collected, thereby more effectively reducing dust pollution and improving the working environment.

[0030] Example 2 Based on Example 1, such as Figures 2-11As shown, it also includes a cleaning mechanism, which is mounted on the guide box 54. The cleaning mechanism includes a reciprocating lead screw 71, which is fixedly connected to both rotating shafts 62. Nuts 72 are threadedly connected to both reciprocating lead screws 71, and sliding frames 73 are fixedly connected to both nuts 72. Several cleaning plates 74 are fixedly connected to both sliding frames 73. Each cleaning plate 74 has an arc-shaped surface. Several cleaning plates 74 located on the same sliding frame 73 form a group. Top rods 81 are fixedly connected to both sliding frames 73. The top rods 81 are slidably connected to the guide box 54. Two fixed rods 82 are fixedly connected to the support frame 3. The two fixed rods 82 are symmetrically arranged. Several top plates 83 are fixedly connected to both fixed rods 82. Each top plate 83 has a triangular structure. Several top plates 83 located on the same fixed rod 82 form a group.

[0031] When the servo motor 61 drives the rotating shaft 62 to rotate, the rotating shaft 62 will drive the reciprocating screw 71 to rotate. The rotation of the reciprocating screw 71 will drive the nut 72, the sliding frame 73, the push rod 81, and several cleaning plates 74 in the same group to move up and down reciprocally through the thread. The two sets of cleaning plates 74 will scrape off the calcium hydroxide particles attached to the two sets of brush rollers 63. The scraped calcium hydroxide particles will be drawn into the guide box 54 by the air pump 56. When the sliding frame 73 drives the push rod 81 to move down or up, the push rod 81 will contact the top plate 83. A group of top plates 83 continuously compress the top rod 81, sliding frame 73, flow guide box 54, and brush roller 63, causing them to move horizontally. The return spring 53 is continuously compressed and reset. The reset of the return spring 53 causes the top rod 81, sliding frame 73, flow guide box 54, and brush roller 63 to move horizontally in the opposite direction and reset. This causes the top rod 81, sliding frame 73, flow guide box 54, and brush roller 63 to move horizontally back and forth. In this way, the contact area between the flow guide box 54 and the calcium hydroxide dust can be increased, thereby enabling more effective suction of calcium hydroxide dust.

[0032] Example 3 Based on Example 2, such as Figures 5-11As shown, it also includes a recycling mechanism, which is mounted on the sliding frame 73. The recycling mechanism includes scraper blades 91. Scraper blades 91 are fixedly connected to the ends of the two sliding frames 73 that are far apart from each other. The scraper blades 91 are in contact with the filter frame 55. Vibrators 92 are fixedly connected to the two scraper blades 91. Discharge hoppers 93 are fixedly connected to the bottom of the two guide boxes 54. The guide boxes 54 are connected to the discharge hoppers 93. A spiral roller 94 is rotatably connected inside the discharge hopper 93. A transmission joint 95 is connected between the spiral roller 94 and the bottom end of the rotating shaft 62. The transmission joint 95 is located outside the discharge hopper 93. A collection bucket 96 is fixedly connected to the discharge hopper 93. The discharge hopper 93 is connected to the collection bucket 96.

[0033] When nut 72 drives sliding frame 73 to move up and down reciprocally, sliding frame 73 will drive scraper 91 and vibrator 92 to move up and down reciprocally. Vibrator 92 will drive scraper 91 to vibrate, so that scraper 91 will vibrate while moving up and down. The scraper 91 will fully scrape off the calcium hydroxide particles attached to filter frame 55 while moving up and down and vibrating. The scraped calcium hydroxide particles will fall down into discharge hopper 93. At the same time, the rotation of shaft 62 will drive spiral roller 94 to rotate through transmission joint 95. The rotation of spiral roller 94 will transfer the calcium hydroxide particles in discharge hopper 93 to collection bucket 96. In this way, the calcium hydroxide particles attached to filter frame 55 can be cleaned and collected, thereby reducing the occurrence of calcium hydroxide particles clogging filter frame 55 and improving working efficiency.
