Description

Technical Field

[0001] This utility model belongs to the field of calcium carbonate production equipment, and in particular a dust removal device for calcium carbonate production. Background Technology

[0002] The production of calcium carbonate generates a large amount of dust. This dust not only pollutes the production environment and affects the health of operators, but also adversely impacts the normal operation of production equipment, such as causing accelerated equipment wear and pipe blockage. Traditional dust collection devices often suffer from low dust collection efficiency, complex structure, and high energy consumption. While existing dust collection devices used in calcium carbonate production can meet basic dust collection needs, they cannot clean the filter plates in a timely manner, leading to reduced dust collection efficiency and affecting the stability and safety of the equipment.

[0003] A search revealed Chinese patent document (authorization announcement number CN208448929U), which discloses a dust removal device for calcium carbonate production. The device includes an air outlet, an air inlet, rollers, a pusher, a barrel filter, a bag filter, a polyester filter, a guide plate, a dust collection chamber, a vacuum extraction port, and a fan. The air inlet is located on the side and the lower left corner of the front, increasing the inlet area and allowing for rapid dust filtration when indoor dust levels are high. This dust removal device achieves four dust removal cycles during use, offering better dust removal performance compared to existing technologies. While this dust removal device for calcium carbonate production meets basic dust removal requirements, the inability to clean the filter plates promptly during dust removal reduces dust removal efficiency and affects the stability and safety of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a dust removal device for calcium carbonate production, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for calcium carbonate production, comprising a calcium carbonate storage box for storing carbonic acid, a top cover installed on the top of the calcium carbonate storage box, a dust removal box installed on the top of the top cover, a cleaning chamber inside the dust removal box, a first motor installed on the side of the cleaning chamber, the output shaft of the first motor connected to a rotating shaft via a coupling, a first filter plate frame welded to one end of the rotating shaft, multiple first filter plates arranged inside the first filter plate frame, a buffer tank connected to the side of the first filter plate frame away from the rotating shaft, a fixing ring rotatably connected to the side of the buffer tank, an air inlet pipe connected to the end of the fixing ring away from the buffer tank, an air outlet pipe connected to the side of the dust removal box, a mating groove provided on the outer periphery of the air outlet pipe, and a fan installed inside the air outlet pipe.

[0006] Preferably, a second motor is installed on the side of the top cover, and the output shaft of the second motor is connected to a Y-shaped frame via a coupling. A second filter plate frame is welded to the end of the Y-shaped frame, and a second filter plate is disposed inside the second filter plate frame.

[0007] Preferably, two support plates are welded to the outer periphery of the air outlet duct, and a rotating column is rotatably installed between the two support plates.

[0008] Preferably, a connecting plate is installed on the outer periphery of the rotating column, and an arc-shaped locking plate is connected to the end of the connecting plate away from the rotating column. A second spring is provided between the rotating column and the support plate.

[0009] Preferably, a third motor is installed on the inner bottom wall of the dust collector, and the output shaft of the third motor is connected to a cam via a coupling. A first sealing plate and a second sealing plate are provided on the outer periphery of the dust collector.

[0010] Preferably, the dust collector has two hollow columns welded to its vertical inner wall, and a first spring is installed inside the two hollow columns. One end of the first spring is connected to a movable column, and the end of the movable column away from the first spring is connected to the cleaning chamber. The bottom wall of the dust collector is provided with a sliding groove, and an impact block is installed on the side of the cleaning chamber.

[0011] Preferably, a support is welded to the outer periphery of the calcium carbonate storage box, a discharge port is provided at the bottom of the calcium carbonate storage box, and a feed port is installed on the top of the top cover.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This dust removal device for calcium carbonate production benefits from the structure of the dust collection box. Dust generated in the calcium carbonate storage box enters the buffer tank through the inlet pipe, then passes through the first filter plate. The first filter plate contacts and adsorbs the dust. The first motor drives the rotating shaft and the first filter plate frame to rotate, and the first filter plate enters the cleaning liquid in the cleaning chamber. The cleaning liquid cleans the first filter plate. The third motor drives the cam to rotate, and the cam contacts the impact block. The impact block drives the cleaning chamber to move along the slide channel towards the inlet pipe. The cooperation of the first spring and the third motor causes the cleaning chamber to reciprocate on the slide channel, causing the cleaning liquid in the cleaning chamber to vibrate, thus cleaning the first filter plate more thoroughly. Compared with traditional dust removal devices for calcium carbonate production, which cannot clean the filter plate in time during dust removal, this structure can clean the filter plate in time, which can improve dust removal efficiency and ensure the stability and safety of the equipment.

[0014] This dust removal device for calcium carbonate production benefits from the structure of the Y-shaped frame and the second filter plate. If the first filter plate is overused, the dust removal effect will weaken, and some dust will come into contact with the second filter plate through the fan. The condition of the second filter plate can be observed to determine whether the first filter plate needs to be removed from the second sealing plate for replacement. The second motor drives the Y-shaped frame and the second filter plate frame to rotate. The used second filter plate rotates away, and the new second filter plate comes into contact with the mating groove to continuously filter and remove dust.

[0015] This dust removal device for calcium carbonate production benefits from the structure of the arc-shaped locking plate. The edge of the second filter plate frame contacts the arc-shaped locking plate. Due to the action of the second spring, the rotating column drives the connecting plate and the arc-shaped locking plate to limit the second filter plate frame, ensuring the stability of dust removal.

Detailed Implementation

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5The dust removal device shown includes a calcium carbonate storage tank 101 for storing carbonic acid. A top cover 104 is installed on the top of the calcium carbonate storage tank 101, and a dust removal box 2 is installed on top of the top cover 104. The dust removal box 2 has a cleaning chamber 4 inside, which can store a mixed solution of organic solvent and water. For example, ethanol or acetone can be mixed with water in a certain proportion, combining the advantages of both organic solvents and water. This mixed solution can both dissolve organic impurities using the organic solvent and clean calcium carbonate dust using water. In practical use, the proportion of ethanol in the ethanol-water mixture can be adjusted between 30% and 70%, depending on the type of impurities on the filter plate and the cleaning requirements. A first motor 210 is installed on the side of the cleaning chamber 4. The output shaft of the first motor 210 is connected to a rotating shaft 209 via a coupling. A first filter plate frame 207 is welded to one end of the rotating shaft 209. Multiple first filter plates 208 are arranged inside the first filter plate frame 207. A buffer tank 206 is connected to the side of the first filter plate frame 207 away from the rotating shaft 209. A fixing ring 205 is rotatably connected to the side of the buffer tank 206. An air inlet pipe 201 is connected to the end of the fixing ring 205 away from the buffer tank 206. The side of the dust box 2 is connected to an air outlet duct 202. The outer periphery of the air outlet duct 202 is provided with a mating groove 304. A fan 211 is installed inside the air outlet duct 202. When the fan 211 is turned on, the dust generated in the calcium carbonate storage box 101 enters the buffer tank 206 through the air inlet duct 201, and then passes through the first filter plate 208. The first filter plate 208 contacts and adsorbs the dust. The dust-removed gas is discharged through the fan 211 and the second filter plate 303. After a period of time, the first motor 210 is turned on. The first motor 210 drives the rotating shaft 209 and the first filter plate frame 207 to rotate. The first filter plate 208 enters the cleaning liquid in the cleaning chamber 4, and the cleaning liquid cleans the first filter plate 208.

[0027] A second motor 301 is mounted on the side of the top cover 104. The output shaft of the second motor 301 is connected to a Y-shaped frame 3 via a coupling. A second filter plate frame 302 is welded to the end of the Y-shaped frame 3. A second filter plate 303 is installed inside the second filter plate frame 302. Two support plates 5 are welded to the outer periphery of the air outlet duct 202. A rotating column 502 is rotatably mounted between the two support plates 5. A connecting plate 503 is mounted on the outer periphery of the rotating column 502. An arc-shaped locking plate 504 is connected to the end of the connecting plate 503 away from the rotating column 502. A second spring 501 is installed between the rotating column 502 and the support plates 5. If the first filter plate 208 is overused, the dust removal effect will decrease. When the dust is weak, some dust comes into contact with the second filter plate 303 through the fan 211. The state of the second filter plate 303 can be observed, and it can be determined whether the first filter plate 208 needs to be removed from the second sealing plate 204 for replacement. The second motor 301 can be turned on, and the second motor 301 drives the Y-shaped frame 3 and the second filter plate frame 302 to rotate. The used second filter plate 303 rotates away, and the new second filter plate 303 comes into contact with the mating groove 304. The edge of the second filter plate frame 302 contacts the arc-shaped locking plate 504. Due to the action of the second spring 501, the rotating column 502 drives the connecting plate 503 and the arc-shaped locking plate 504 to limit the second filter plate frame 302.

[0028] A third motor 402 is installed on the inner bottom wall of the dust collector 2. The output shaft of the third motor 402 is connected to a cam 403 through a coupling. A first sealing plate 203 and a second sealing plate 204 are provided on the outer periphery of the dust collector 2.

[0029] Two hollow columns 405 are welded to the vertical inner wall of the dust collector 2. A first spring 406 is installed inside each hollow column 405. One end of the first spring 406 is connected to a movable column 407. The end of the movable column 407 away from the first spring 406 is connected to the cleaning chamber 4. A sliding groove 404 is provided on the inner bottom wall of the dust collector 2. An impact block 401 is installed on the side of the cleaning chamber 4. When the third motor 402 is turned on, it drives the cam 403 to rotate. The cam 403 interacts with the impact block 406. Upon contact, the impact block 401 drives the cleaning chamber 4 to move along the slide 404 towards the air intake pipe 201. The cleaning chamber 4 squeezes the moving column 407 and the first spring 406. Due to the action of the first spring 406, the first spring 406 pushes the moving column 407 and the cleaning chamber 4 to move in opposite directions. With the cooperation of the first spring 406 and the third motor 402, the cleaning chamber 4 reciprocates on the slide 404, causing the cleaning liquid in the cleaning chamber 4 to vibrate, thus cleaning the first filter plate 208 more thoroughly.

[0030] A support 1 is welded to the outer periphery of the calcium carbonate storage box 101. A discharge port 102 is provided at the bottom of the calcium carbonate storage box 101, and a feed port 103 is installed on the top of the top cover 104. Calcium carbonate is poured into the calcium carbonate storage box 101 through the feed port 103, and the calcium carbonate in the calcium carbonate storage box 101 can be recovered through the discharge port 102.

[0031] Working principle

[0032] This dust removal device, used in calcium carbonate production, operates by pouring calcium carbonate into a calcium carbonate storage tank 101 through the feed inlet 103. The fan 211 is then turned on, and the dust generated in the storage tank 101 enters the buffer tank 206 through the air inlet pipe 201. The dust then passes through the first filter plate 208, where it comes into contact with and adsorbs the dust. The dust-removed gas is then discharged through the fan 211 and the second filter plate 303. After a period of time, the first motor 210 is turned on, driving the rotating shaft 209 and the second filter plate 206. When the filter plate holder 207 rotates, the first filter plate 208 enters the cleaning solution in the cleaning chamber 4, and the cleaning solution cleans the first filter plate 208. The third motor 402 is then activated, driving the cam 403 to rotate. The cam 403 contacts the impact block 401, which in turn moves the cleaning chamber 4 along the slide groove 404 towards the air intake pipe 201. The cleaning chamber 4 compresses the moving column 407 and the first spring 406. Due to the action of the first spring 406, the first spring 406 pushes the moving column 407. The cleaning chamber 4 moves in the opposite direction to the cleaning chamber 4. The cooperation of the first spring 406 and the third motor 402 causes the cleaning chamber 4 to reciprocate on the slide 404, vibrating the cleaning fluid inside the cleaning chamber 4 to more thoroughly clean the first filter plate 208. If the first filter plate 208 is overused, its dust removal effect weakens, and some dust comes into contact with the second filter plate 303 through the fan 211. The condition of the second filter plate 303 can be observed to determine whether the first filter plate 208 needs to be removed from the second sealing plate 204 for replacement. The second motor 301 is started, which drives the Y-shaped frame 3 and the second filter plate frame 302 to rotate. The used second filter plate 303 rotates away, and the new second filter plate 303 engages with the mating groove 304. The edge of the second filter plate frame 302 contacts the arc-shaped locking plate 504. Due to the action of the second spring 501, the rotating column 502 drives the connecting plate 503 and the arc-shaped locking plate 504 to limit the second filter plate frame 302, so that the calcium carbonate in the calcium carbonate storage box 101 can be recovered from the discharge port 102.
