A dust treatment device for corundum sand production

Abstract

This invention discloses a dust treatment device for corundum sand production, relating to the field of corundum sand production technology. It includes a dust absorption mechanism and a suction pipe installed on one side of the dust absorption mechanism. A dust treatment mechanism is located on one side of the dust absorption mechanism, and a filter box is located on one side of the dust treatment mechanism. The dust absorption mechanism includes a dust absorption sleeve, with a first rotating shaft located at the center of the sleeve. A dispersing rotating disk is fixedly installed on one side of the first rotating shaft and is rotatably connected to the dust absorption sleeve. Several dispersing spiral plates are fixedly installed on the outer side of the first rotating shaft. Because the antistatic spray contains a certain amount of water, it not only provides initial dust reduction but also prevents static electricity buildup, thus avoiding the potential for explosions due to excessively high dust concentrations. Since the suction pipe is mostly made of metal, static sparks could generate and come into contact with alumina dust.

Description

Technical Field

[0001] This invention relates to the field of corundum sand production technology, specifically to a dust treatment device for corundum sand production. Background Technology

[0002] Corundum is a gemstone formed from the crystallization of aluminum oxide. Corundum generally includes ruby ​​and sapphire. Ruby refers to corundum with metallic chromium, which is bright red in color, while sapphire refers to corundum of colors other than red. Due to its excellent thermal properties, electrical properties, corrosion resistance, and infrared transmission, corundum has a wide range of applications in the field of optical devices. Corundum abrasive can polish the rough surface of any workpiece to a fine finish, making it one of the most economical abrasives. This sharp, angular synthetic abrasive has a hardness second only to diamond, making it particularly suitable for use when there are strict requirements for iron contamination.

[0003] Publication No. CN215962737U discloses an environmental treatment device for the production of brown fused alumina sand. A water pump draws water from a tank into a water pipe, which then enters a hollow rotating column. The water then flows through the column into a strip tube and is finally sprayed out through multiple nozzles. As the nozzles spray, the strip tube rotates, causing the nozzles to spread outwards, increasing coverage and improving the contact between water and airflow, thus enhancing dust suppression. A filter screen filters the used water for reuse, achieving water resource recycling and effectively conserving water. A scraper cleans impurities from the filter screen, further improving its filtration efficiency. However, this patent has the following problems in practical use:

[0004] Although the environmental treatment device for the production of brown corundum sand uses water spraying to reduce dust, in the prior art, in order to improve the service life of the dust suction pipe, most of the dust collection pipes are made of metal. However, metal pipes are subject to static electricity. When the dust concentration is too high and comes into contact with an open flame or static electricity, a fire is likely to occur, which is not conducive to the safety of corundum sand production. At the same time, it is not convenient to recycle the alumina powder after dust reduction, thus causing a waste of resources.

[0005] Therefore, a dust treatment device for corundum sand production is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a dust treatment device for corundum sand production, in order to solve the problems mentioned in the background art. In order to improve the service life of the dust suction pipe, the prior art mostly uses metal materials before dust collection. However, metal pipes are subject to static electricity. When the dust concentration is too high and comes into contact with open flame or static electricity, it is easy to cause a fire, which is not conducive to the safety of corundum sand production.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: This dust treatment device for corundum sand production, because the anti-static spray contains a certain amount of water, not only plays a preliminary role in dust reduction but also has an anti-static effect. This prevents the explosion caused by excessively high dust concentrations, as the suction pipe is mostly made of metal, which could generate static sparks upon contact with alumina dust. The cleaning ring scraper cleans the alumina dust adhering to the inner wall of the dust treatment box, avoiding waste of alumina dust. Simultaneously, the fixed connecting rod drives the bottom atomizer to move up and down, further uniformly spraying water mist inside the dust treatment box, allowing the water mist to fully mix with the alumina powder, thereby improving the dust reduction effect. The specific details are as follows:

[0022] 1. By setting up a dust absorption mechanism, not only can the dust absorption fan inside the dust suction pipe generate a certain amount of absorption, thereby absorbing the dust generated during the production of corundum sand, but when the dust enters the dust absorption pipe, the spray pump is activated to pump the anti-static spray inside the spray box into the anti-static spray ring through the spray connection pipe, and then spray it out through the first nozzle, allowing the dust to come into contact with the anti-static spray. Since the anti-static spray contains a certain amount of water, it not only plays a preliminary role in dust reduction, but also has an anti-static effect, preventing the dust concentration from being too high. Because the dust suction pipe is mostly made of metal, it will generate a certain amount of static sparks, which will come into contact with the alumina dust, thus producing... The explosion phenomenon is detrimental to the safety of corundum sand production. When dust enters the interior of the dust absorption sleeve, the suction force will cause the dispersing spiral plate to drive the first rotating shaft and the dispersing rotating disk to rotate. The antistatic spray and dust are fully mixed in the dispersing holes, thereby reducing the dust concentration and further preventing the dust explosion phenomenon. By starting the first rotating motor to drive the rotating gear to rotate, the meshing connection between the rotating gear and the meshing toothed ring is utilized to drive the rotating bearing to rotate. Under the action of the rotating balls, the dust absorption sleeve and dust absorption tube can be rotated, thereby achieving all-round dust absorption and improving the dust reduction efficiency.

[0023] 2. By setting up a dust treatment mechanism, not only can the second rotating motor drive the rotating worm gear, but the meshing connection between the rotating worm gear and the rotating worm wheel can also cause the rotating connecting disc and the second rotating disc to rotate. Under the action of the second rotating disc, the lifting ring and the cleaning ring scraper can rotate. At the same time, the fixed connecting rod drives the bottom atomizer to rotate, and the fixed connecting ring drives the top atomizer to rotate. The top and bottom atomizers can evenly spray water mist into the interior of the dust treatment box, achieving a secondary dust reduction effect. Simultaneously, the third rotating motor is activated to drive the lifting threaded rod to rotate, causing the lifting threaded sleeve to move the fixed connecting rod, the lifting ring, and the cleaning ring scraper up and down. This not only allows the cleaning ring scraper to clean the alumina dust adhering to the inner wall of the dust treatment box, but also avoids the waste of alumina dust. Simultaneously, the fixed connecting rod drives the bottom atomizer to rise and move, further evenly spraying water mist into the interior of the dust treatment box, allowing the water mist to fully mix with the alumina powder, thereby improving the dust reduction effect. The mixture of alumina powder and water can be discharged into the filter box through the drain pipe. The filter cloth inside the filter bracket can filter the alumina powder, and the filtered water can enter the collection water tank for recycling through the guide chute. At the same time, the cleaning box doors on both sides are opened, and the cleaning motor is started to drive the sprocket drive assembly and the cleaning threaded rod to rotate, causing the cleaning threaded sleeve to drive the cleaning bracket and cleaning brush to move, which can clean the alumina powder filtered from the surface of the filter bracket into the drying plates on both sides. The drying plates contain desiccants such as silica gel, which can absorb the moisture on the surface of the alumina powder, facilitating the recycling of the alumina powder.

Detailed Implementation

[0036] 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.

[0037] Please see Figures 1-4The present invention provides a technical solution: a dust treatment device for corundum sand production, comprising a dust absorption mechanism 1 and a dust suction pipe 113 installed on one side of the dust absorption mechanism 1. A dust treatment mechanism 2 is provided on one side of the dust absorption mechanism 1, and a filter box 224 is provided on one side of the dust treatment mechanism 2. The dust absorption mechanism 1 includes a dust absorption sleeve 101, a first rotating shaft 102 is provided at the center of the dust absorption sleeve 101, and a dispersing rotating disk 103 is fixedly installed on one side of the first rotating shaft 102. The dispersing rotating disk 103 is rotatably connected to the dust absorption sleeve 101, and the outer side of the first rotating shaft 102 is fixedly connected to the dust absorption sleeve 101. A plurality of dispersing spiral plates 104 are fixedly installed, wherein the dispersing spiral plates 104 have dispersing holes 105 inside. A plurality of dust absorption pipes 106 are fixedly installed on the outside of the dust absorption sleeve 101. An antistatic spray ring 107 is fixedly installed inside the dust absorption pipe 106. A first nozzle 108 is fixedly installed on the inner side of the antistatic spray ring 107. A spray pump 109 is fixedly installed on one side of the dust absorption pipe 106. A spray connecting pipe 110 is fixedly installed at the end of the spray pump 109. A spray box 111 is fixedly installed at the end of the spray connecting pipe 110 away from the spray pump 109. A sealing device is threaded to the top of the spray box 111. Inside the suction pipe 113 (plug 112), a fan bracket 114 is fixedly installed. Inside the fan bracket 114, a suction fan 115 is fixedly installed. A dust cover is provided on the outside of the suction fan 115. The suction fan 115 inside the suction pipe 113 generates a certain amount of absorption, thereby absorbing the dust generated in the production of corundum sand. When the dust enters the dust absorption pipe 106, the spray pump 109 is started to pump the antistatic spray inside the spray box 111 into the antistatic spray ring 107 through the spray connection pipe 110, and spray it out through the first nozzle 108, so that the dust can come into contact with the antistatic spray. Because the antistatic spray contains a certain amount of antistatic spray, the dust can be effectively absorbed. The measured amount of water not only serves as a preliminary dust suppression agent but also provides an anti-static effect. This prevents the formation of static sparks from the suction pipe 113, which is mostly made of metal, due to excessive dust concentration. These sparks could come into contact with alumina dust, potentially causing an explosion and compromising the safety of corundum sand production. When dust enters the dust absorption sleeve 101, the suction force causes the dispersing spiral plate 104 to rotate the first rotating shaft 102 and the dispersing rotating disk 103. This allows the anti-static spray to mix thoroughly with the dust through the dispersing holes 105, thereby reducing the dust concentration and further preventing dust explosions.

[0038] Please see Figures 2-5A motor bracket 116 is fixedly installed at the bottom of the suction pipe 113. A first rotating motor 117 is fixedly installed at the bottom of the motor bracket 116.

A rotating bearing 120 is fixedly installed inside the meshing gear ring 119. A rotating ball 121 is rotatably connected inside the rotating bearing 120. The rotating bearing 120 is rotatably connected to the suction pipe 113 through the rotating ball 121. The rotating bearing 120 is fixedly connected to the dust absorption sleeve 101. By starting the first rotating motor 117, the rotating gear 118 is driven to rotate. Utilizing the meshing connection between the rotating gear 118 and the meshing gear ring 119, the meshing gear ring 119 drives the rotating bearing 120 to rotate. Under the action of the rotating ball 121, the dust absorption sleeve 101 and the dust absorption pipe 106 can be rotated, thereby achieving all-round dust absorption and improving dust reduction efficiency.

The second rotating motor 203 drives the rotating worm 204 to rotate. Utilizing the meshing connection between the rotating worm 204 and the rotating worm wheel 205, the rotating worm wheel 205 drives the rotating connecting plate 206 and the second rotating plate 209 to rotate. Under the action of the second rotating plate 209, it can... The system enables the rotation of the lifting ring 213 and the cleaning ring scraper 214. Simultaneously, the fixed connecting rod 212 drives the bottom atomizer 215 to rotate, and the fixed connecting ring 218 drives the top atomizer 217 to rotate. Through the top atomizer 217 and the bottom atomizer 215, water mist is evenly sprayed onto the interior of the dust treatment box 201, achieving a secondary dust reduction effect. Simultaneously, the third rotating motor 207 is activated, driving the lifting threaded rod 210 to rotate. This causes the lifting threaded sleeve 211 to move the fixed connecting rod 212, the lifting ring 213, and the cleaning ring scraper 214 up and down. This not only allows the cleaning ring scraper 214 to clean the alumina dust adhering to the inner wall of the dust treatment box 201, but also prevents the waste of alumina dust.Simultaneously, the fixed connecting rod 212 drives the bottom atomizer 215 to move up and down, further uniformly spraying water mist into the interior of the dust treatment box 201, allowing the water mist to fully mix with the alumina powder, thereby improving the dust suppression effect.

Second support legs 239 are fixedly installed around the filter box 224. The mixture of alumina powder and water can be discharged into the filter box 224 through the drain pipe 223. The alumina powder can be filtered through the filter cloth set inside the filter support 228. The filtered water enters the water collection tank 238 through the guide trough 237 for recycling. At the same time, the cleaning box doors 226 on both sides are opened, and the cleaning motor 231 is started to drive the sprocket transmission assembly 232 and the cleaning threaded rod 233 to rotate. The cleaning threaded sleeve 234 drives the cleaning support 235 and the cleaning brush 236 to move. The alumina powder filtered from the surface of the filter support 228 can be cleaned into the drying plates 229 on both sides. The drying plates 229 contain desiccants such as silica gel, which can absorb the moisture on the surface of the alumina powder and facilitate the recycling of the alumina powder.

[0041] Working principle: Before using this dust treatment device for corundum sand production, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the dust suction fan 115 inside the suction pipe 113 absorbs the dust generated during corundum sand production. When the dust enters the dust absorption pipe 106, the spray pump 109 is activated to pump the antistatic spray inside the spray box 111 into the antistatic spray ring 107 through the spray connection pipe 110, and then sprays it out using the first nozzle 108, allowing the dust to come into contact with the antistatic spray. Since the antistatic spray contains a certain amount of water, it not only plays a preliminary role in dust reduction but also has an antistatic effect, preventing the dust concentration from being too high. Because the suction pipe 113 is mostly made of metal, it may generate static sparks that could cause an explosion upon contact with the alumina dust, which would be detrimental to the corundum sand production. To ensure production safety, when dust enters the dust absorption sleeve 101, the suction force causes the dispersing spiral plate 104 to drive the first rotating shaft 102 and the dispersing rotating disk 103 to rotate. The antistatic spray is fully mixed with the dust through the dispersing hole 105, thereby reducing the dust concentration and further preventing dust explosions. By starting the first rotating motor 117, the rotating gear 118 is driven to rotate. Utilizing the meshing connection between the rotating gear 118 and the meshing gear ring 119, the meshing gear ring 119 drives the rotating bearing 120 to rotate. Under the action of the rotating ball bearing 121, the dust absorption sleeve 101 and the dust absorption tube 106 can be rotated, thereby achieving all-round dust absorption and improving dust reduction efficiency.

[0042] Secondly, the second rotating motor 203 drives the rotating worm 204 to rotate. Utilizing the meshing connection between the rotating worm 204 and the rotating worm wheel 205, the rotating worm wheel 205 drives the rotating connecting disc 206 and the second rotating disc 209 to rotate. Under the action of the second rotating disc 209, the lifting ring 213 and the cleaning ring scraper 214 can rotate. Simultaneously, the fixed connecting rod 212 drives the bottom atomizer 215 to rotate, and the fixed connecting ring 218 drives the top atomizer 217 to rotate. Through the top atomizer 217 and the bottom atomizer 215, water mist can be evenly sprayed inside the dust treatment box 201. This method achieves a secondary dust reduction effect. Simultaneously, the third rotating motor 207 is activated to drive the lifting threaded rod 210 to rotate, causing the lifting threaded sleeve 211 to move the fixed connecting rod 212, the lifting ring 213, and the cleaning ring scraper 214 up and down. This not only allows the cleaning ring scraper 214 to clean the alumina dust adhering to the inner wall of the dust treatment box 201, avoiding waste of alumina dust, but also, through the fixed connecting rod 212, drives the bottom atomizer 215 to move up and down, further uniformly spraying water mist inside the dust treatment box 201, so that the water mist can be fully mixed with the alumina powder, thereby improving the dust reduction effect.

[0043] Finally, the mixture of alumina powder and water is discharged into the filter box 224 through the drain pipe 223. The alumina powder is filtered by the filter cloth inside the filter bracket 228, and the filtered water enters the collection tank 238 through the guide trough 237 for recycling. At the same time, the cleaning box doors 226 on both sides are opened, and the cleaning motor 231 is started to drive the sprocket drive assembly 232 and the cleaning threaded rod 233 to rotate. This causes the cleaning threaded sleeve 234 to move the cleaning bracket 235 and the cleaning brush 236, which can clean the alumina powder filtered from the surface of the filter bracket 228 into the drying plates 229 on both sides. The drying plates 229 contain desiccants such as silica gel, which can absorb the moisture on the surface of the alumina powder, making it easier to recycle the alumina powder.
