Description

Technical Field

[0001] The present invention relates to the technical field of corundum sand production, and specifically to a dust treatment device for corundum sand production. Background Art

[0002] Corundum is a gemstone formed by the crystallization of alumina. Corundum generally includes ruby and sapphire. Ruby refers to corundum doped with metal chromium and having a bright red color, and sapphire refers to corundum of other colors except red. Due to its good thermal properties, electrical properties, corrosion resistance, and infrared transmission properties, corundum has a wide range of applications in the field of optical devices. Corundum sand can polish the rough surface of any workpiece finely and is one of the most economical abrasives. This sharp and angular synthetic abrasive has a hardness second only to diamond and is especially suitable for use when strict requirements are imposed on iron contamination.

[0003] Patent Publication No. CN215962737U discloses an environmental treatment device for brown corundum sand production. The water pump provided will pump the water in the water tank into the water pipe. The water pumped into the water pipe will enter the inside of the hollow rotating column, then enter the strip-shaped pipe through the hollow rotating column, and finally be sprayed out through multiple nozzles. When the multiple nozzles are spraying, the strip-shaped pipe will drive the multiple nozzles to rotate, so as to achieve the purpose of the water spreading around, improve the coverage range, and further increase the contact between the water and the air flow, thereby further improving the dust reduction effect. The used water can be filtered through the provided filter screen and then reused, so as to realize the recycling of water resources and effectively save water resources. Moreover, through the provided scraper, the impurities on the filter screen can be cleaned, further improving the filtering effect of the filter screen. However, the following problems still exist in the actual use of this patent: Although the environmental treatment device for brown corundum sand production reduces dust by spraying water, before collecting the dust, in the prior art, in order to improve the service life of the dust suction pipe, most are made of metal materials, and there is an electrostatic phenomenon in the metal pipe. When the dust concentration is too high and contacts open fire or static electricity, it is easy to cause a fire, 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, resulting in a waste of resources.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For this dust treatment device for corundum sand production, since the antistatic spray contains a certain amount of water, it can not only play a role in preliminary dust reduction, but also play an antistatic effect, avoiding the phenomenon that due to the high concentration of inhaled dust and the fact that the dust suction pipes are mostly made of metal, certain electrostatic sparks will be generated and come into contact with alumina dust, thus causing an explosion. The cleaning annular scraper is used to clean the alumina dust adhering to the inner wall of the dust treatment box, avoiding the waste of alumina dust. At the same time, the bottom atomizer is driven to move up and down by the fixed connecting rod to further evenly spray water mist inside the dust treatment box, enabling the water mist to fully mix with the alumina powder, thereby improving the dust reduction effect. The specific content is as follows: 1. By setting the dust absorption mechanism, not only can a certain absorption be generated by the dust suction fan inside the dust suction pipe to absorb the dust generated during corundum sand production. When the dust enters the dust absorption pipe, the spray pump is started to pump the antistatic spray inside the spray box into the antistatic spray ring through the spray connection pipe and spray it out through the first nozzle, enabling the dust to come into contact with the antistatic spray. Since the antistatic spray contains a certain amount of water, it can not only play a role in preliminary dust reduction, but also play an antistatic effect, avoiding the phenomenon that due to the high concentration of inhaled dust and the fact that the dust suction pipes are mostly made of metal, certain electrostatic sparks will be generated and come into contact with alumina dust, thus causing an explosion, which is not conducive to the safety of corundum sand production. When the dust enters the inside of the dust absorption sleeve, due to the suction force, the dispersion spiral plate will drive the first rotating shaft and the dispersion rotating disc to rotate. In the dispersion holes, the antistatic spray is fully mixed with the dust, thus achieving the effect of reducing the dust concentration and further avoiding the phenomenon of dust explosion. By starting the first rotating motor to drive the rotating gear to rotate, using the characteristic of the meshing connection between the rotating gear and the meshing tooth ring, the meshing tooth ring drives the rotating bearing to rotate. Under the action of the rotating balls, the rotation of the dust absorption sleeve and the dust absorption pipe can be realized, thereby achieving all-round dust absorption and improving the dust reduction efficiency; 2. By setting up the dust treatment mechanism, not only can the second rotating motor drive the rotating worm to rotate, and by utilizing the meshing connection between the rotating worm and the rotating worm gear, the rotating worm gear drives the rotating connection disk and the second rotating disk to rotate. Under the action of the second rotating disk, the lifting ring and the cleaning annular scraper can be rotated. 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. Through the top atomizer and the bottom atomizer, the inside of the dust treatment box can be evenly sprayed with water mist. By spraying water mist, the secondary dust reduction effect can be achieved. At the same time, the third rotating motor is started to drive the lifting threaded rod to rotate, so that the lifting threaded sleeve drives the fixed connecting rod, the lifting ring and the cleaning annular scraper to move up and down. Not only can the cleaning annular scraper be used to clean the alumina dust attached to the inner wall of the dust treatment box, avoiding the waste of alumina dust, but also the bottom atomizer can be driven to move up and down by the fixed connecting rod, further evenly spraying water mist inside the dust treatment box, so that the water mist can be fully mixed 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 sewage pipe. The alumina powder can be filtered through the filter cloth arranged inside the filter bracket, and the filtered water enters the collection water tank through the guide trough for recycling. At the same time, the cleaning box doors on both sides are opened, and the cleaning motor is started to drive the sprocket transmission assembly and the cleaning threaded rod to rotate, so that the cleaning threaded sleeve drives the cleaning bracket and the cleaning brush to move, and the alumina powder filtered on the surface of the filter bracket can be cleaned into the drying plates on both sides. Desiccants such as silica gel are placed inside the drying plates, which can absorb the moisture on the surface of the alumina powder, facilitating the recycling of the alumina powder.

[0023] Working principle: Before using this dust treatment device for corundum sand production, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 11As shown in the figure, first, a certain suction is generated by the suction fan 115 inside the suction pipe 113 to absorb the dust generated during the production of corundum sand. When the dust enters the dust absorption pipe 106, the spray pump 109 is started to pump the anti-static spray inside the spray box 111 into the anti-static 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 anti-static spray. Since the anti-static spray contains a certain amount of water, it can not only play a role in preliminary dust reduction, but also achieve the effect of anti-static, avoiding the phenomenon of explosion caused by the contact between the static spark generated due to the high concentration of inhaled dust and the alumina dust, which is not conducive to the safety of corundum sand production. When the dust enters the inside of the dust absorption sleeve 101, due to the suction force, the dispersion spiral plate 104 will drive the first rotating shaft 102 and the dispersion rotating disk 103 to rotate. In the dispersion holes 105, the anti-static spray and the dust are fully mixed, so as to achieve the effect of reducing the dust concentration and further avoid the phenomenon of dust explosion. By starting the first rotating motor 117 to drive the rotating gear 118 to rotate, and using the meshing connection between the rotating gear 118 and the meshing tooth ring 119, the meshing tooth ring 119 drives the rotating bearing 120 to rotate. Under the action of the rotating balls 121, the dust absorption sleeve 101 and the dust absorption pipe 106 can rotate, so as to achieve all-round dust absorption and improve the dust reduction efficiency.

[0024] Secondly, the second rotating motor 203 is used to drive the rotating worm 204 to rotate. By using the meshing connection between the rotating worm 204 and the rotating worm wheel 205, the rotating worm wheel 205 drives the rotating connection disk 206 and the second rotating disk 209 to rotate. Under the action of the second rotating disk 209, the lifting ring 213 and the cleaning annular scraper 214 can rotate. At the same time, 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, the inside of the dust treatment box 201 can be evenly sprayed with water mist. By spraying water mist, the effect of secondary dust reduction can be achieved. At the same time, the third rotating motor 207 is started to drive the lifting threaded rod 210 to rotate, so that the lifting threaded sleeve 211 drives the fixed connecting rod 212, the lifting ring 213 and the cleaning annular scraper 214 to move up and down. It can not only use the cleaning annular scraper 214 to clean the alumina dust attached to the inner wall of the dust treatment box 201 to avoid the waste of alumina dust, but also drive the bottom atomizer 215 to move up and down through the fixed connecting rod 212 to further evenly spray 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.

[0025] Finally, the mixture of alumina powder and water can be discharged into the filter box 224 through the sewage pipe 223. The alumina powder can be filtered through the filter cloth arranged inside the filter bracket 228, so that the filtered water enters the collection water tank 238 through the material guiding groove 237 for recycling. At the same time, open the cleaning box doors 226 on both sides, start the cleaning motor 231 to drive the sprocket transmission assembly 232 and the cleaning threaded rod 233 to rotate, so that the cleaning thread sleeve 234 drives the cleaning bracket 235 and the cleaning brush 236 to move, and the alumina powder filtered on the surface of the filter bracket 228 can be cleaned into the drying plates 229 on both sides. Desiccants such as silica gel are placed inside the drying plates 229, which can absorb the moisture on the surface of the alumina powder and facilitate the recycling of the alumina powder.
