Description
Technical Field
[0001] The present invention relates to the technical field of sieving old quartz sand, and in particular to a device and process for sieving old quartz sand filter media. Background Art
[0002] With the development of industry and construction, the recycling of old quartz sand has been widely used in many fields. However, during the use of quartz sand, certain impurities such as fine particles, dust, and soil are often mixed in. These impurities not only affect the purity and quality of quartz sand but also may affect its subsequent use effect. Therefore, the screening and purification of quartz sand are particularly important.
[0003] Traditional screening techniques generally use a screening plate for screening. The impurities in the quartz sand are screened out through holes on the screening plate. During the screening process, the screening holes on the screening plate are easily blocked by impurities, resulting in poor screening effects. Over time, the screening holes of the screening plate may gradually lose their original screening effect due to the accumulation of impurities, thus affecting the screening accuracy and efficiency of quartz sand. In addition, traditional screening devices often generate a large amount of dust during the screening process, especially for fine-particle quartz sand, and the dust pollution is serious, affecting the operating environment and the health of personnel. Although some devices can reduce the generation of dust by spraying water, these devices often do not consider the reuse of water, resulting in waste of water resources. The waste of water resources not only increases the operating cost but also causes a certain burden on the environment. Summary of the Invention
[0004] The present invention provides a device and process for sieving old quartz sand filter media. When using the device of the present invention, it can prevent the screening holes on the screening plate from being blocked, affecting the screening efficiency of quartz sand, and further improve the screening effect of the device. When screening quartz sand, it stirs and turns the quartz sand to accelerate the falling of particles, reduce the adhesion between particles, and improve the screening accuracy and efficiency. When the device screens quartz sand, it sprays water to inhibit the generation of dust during the screening of quartz sand, and at the same time, it can increase the lubricity of particles, reduce the friction between particles, improve the practicability of the device, and at the same time, the water can be reused multiple times to save resources.

After screening, the impurities fall out of the inside of the screening bin through the screening plate. The baffle can slide in the inner wall of the groove plate. By pushing the push plate to drive the baffle to move, the baffle can be removed from the groove plate.

At the same time, control the output end of the hydraulic rod to move up and down, further causing the plurality of stirring plates to move up and down back and forth. When the plurality of stirring plates move up and down back and forth, they turn the quartz sand inside the screening bin up and down, reducing the adhesion between the particles, increasing the contact surface for screening, and contributing to the stratification of the particles.

Pour water into the water tank. By turning on the external power switch of the delivery pump, a suction force is generated at the input end of the delivery pump, and further the water inside the water tank is sucked through the first conduit. The first conduit sucks the water inside the water tank through the suction head.

When the plurality of stirring plates move up and down back and forth, turn the quartz sand inside the screening bin up and down; Further open the valve of the second discharge pipe cross bar, the mixed material passes through the second discharge pipe cross bar and comes to the inside of the grinding cylinder screening plate, turn on the external power of the drive motor sleeve, and the output shaft of the drive motor sleeve drives the transmission rod scraper to rotate; Further turn on the external power switch of the bidirectional motor, and then the output shaft of the bidirectional motor drives the threaded rod to rotate. The sliding cylinder is connected together through the scraper and the sleeve, and the two sliding plates can slide on both sides of the inner wall of the screening bin. When the threaded rod rotates in different directions, the sleeve moves back and forth on the outer surface of the threaded rod. The two second telescopic rods can slide inside the two first telescopic rods respectively. The two springs have elasticity, and the elasticity of the two springs pushes the two second telescopic rods, further making one side of the scraper close to one side of the screening plate. Control the output shaft of the bidirectional motor to rotate back and forth, further make the sleeve move back and forth on the outer surface of the threaded rod, and further drive the scraper to move back and forth on one side of the screening plate. For the material that has been ground for the first time, turn on the external power switch of the transfer pump. Then, the input end of the transfer pump generates suction, further sucks the water inside the water tank through the first conduit. Under the action of the transfer pump, it is discharged into the two second conduits through the two ports of the Y-shaped through pipe, and further discharged into the two hollow cylinders. Sprinkle water on the inside of the screening bin through a plurality of nozzles, and further sprinkle it on the quartz sand. The first conduit sucks the water inside the water tank through the suction head. The impurities in the water can be filtered through the partition net, and the contact area between the suction head and the water is increased through the suction head; After the screening of the quartz sand is completed, open the valve on the drainage pipe, and the water and impurities inside the water tank flow out through the drainage pipe.
[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. When the present invention is in use, when screening quartz sand, multiple stirring rods and multiple stirring plates stir the quartz sand inside the screening bin. At this time, turn on the external power switch of the bidirectional motor, and then the output shaft of the bidirectional motor drives the threaded rod to rotate. Since the sliding cylinder can slide on the outer surface of the cross bar, the sliding cylinder is connected to the scraper through the sleeve, and the two sliding plates can slide on both sides of the inner wall of the screening bin. Therefore, when the threaded rod rotates in different directions, the sleeve moves back and forth on the outer surface of the threaded rod. The two second telescopic rods can slide inside the two first telescopic rods respectively. The two springs have elasticity, and the elastic force of the two springs pushes the two second telescopic rods, further making one side of the scraper closely adhere to one side of the screening plate. Control the output shaft of the bidirectional motor to rotate back and forth, further making the sleeve move back and forth on the outer surface of the threaded rod, and further driving the scraper to move back and forth on one side of the screening plate. When sand or impurities block the screening holes on the screening plate, the moving back and forth scraper will push the blocked impurities or sand, preventing the blocking of the screening holes of the screening plate from affecting the screening efficiency. After the screening is completed, the impurities fall out of the inside of the screening bin through the screening plate. The baffle can slide on the inner wall of the groove plate. By pushing the push plate to drive the baffle to move, the baffle is removed from the groove plate. At this time, the baffle does not block the discharge port on the screening bin, and the quartz sand on the screening plate can be scraped out of the inside of the screening bin. Therefore, when using the device, it can prevent the screening holes on the screening plate from being blocked, affecting the screening efficiency of quartz sand, and further improving the screening effect of the device.
[0015] 2. When the present invention screens old quartz sand, pour the quartz sand into the inside of the screening bin. The quartz sand is on the screening plate, and the impurities in the quartz sand are screened through the screening holes on the screening plate. By controlling the switch of the hydraulic rod, the fixed ring makes the hydraulic rod installed on the support plate, which has a supporting effect on the above structure. At this time, the output end of the hydraulic rod drives the connecting rod to move. Turn on the external power switch of the driving motor, and then the output shaft of the driving motor drives the connecting rod to rotate. The driving motor is installed inside the protection box, which has a protective effect on the driving motor to prevent it from being damaged due to being exposed. Then the connecting rod drives multiple stirring rods and multiple stirring plates to rotate. The rotating multiple stirring rods and multiple stirring plates stir the quartz sand inside the screening bin, preventing the quartz sand from accumulating together, accelerating the falling of particles, enabling fine particles to quickly pass through the screening plate, and at the same time controlling the output end of the hydraulic rod to move up and down back and forth, further making the multiple stirring plates move up and down back and forth. When the multiple stirring plates move up and down back and forth, they turn the quartz sand inside the screening bin up and down, reducing the adhesion between particles, increasing the screening contact surface, and helping the particles to be stratified. Therefore, when screening quartz sand, by stirring and turning it, it accelerates the falling of particles, reduces the adhesion between particles, and improves the screening accuracy and efficiency.
[0016] 3. When screening quartz sand in the present invention, water is poured into the water tank. By turning on the external power switch of the transfer pump, suction is generated at the input end of the transfer pump. Further, the water inside the water tank is sucked through the first conduit. Under the action of the transfer pump, it is discharged into the two second conduits through the two ports of the Y-shaped pipe, and further into the two hollow cylinders. Water is sprayed inside the screening bin through multiple nozzles, and further onto the quartz sand, suppressing the generation of dust during the screening of quartz sand. At the same time, it can increase the lubricity of the particles, reduce the friction between the particles. The impurities and water fall through the screening holes on the screening plate to the lower part of the screening bin. Through the inclined surface of the screening plate, they are guided into the water tank for secondary utilization. The first conduit sucks the water inside the water tank through the suction head. The impurities in the water can be filtered through the partition net. The contact area between the suction head and the water is increased through the suction head. After the screening of quartz sand is completed, by opening the valve on the drainage pipe, the water and impurities inside the water tank flow out through the drainage pipe. Thus, when the device screens quartz sand, water is sprayed to suppress the generation of dust during the screening of quartz sand. At the same time, it can increase the lubricity of the particles, reduce the friction between the particles, improve the practicability of the device, and at the same time, the water can be utilized multiple times to save resources.

Under the action of the delivery pump 405, it is discharged into the interiors of two second conduits 407 through the two ports of the Y-shaped pipe 406.
[0028] Please refer to Figures 1-9 , in one embodiment, both ends of the Y-shaped pipe 406 are installed with second conduits 407 through flanges.

[0029] Please refer to Figures 1-9 , in one embodiment, a drainage pipe 410 is installed on one side of the water tank 401. A valve is installed on the outer surface of the drainage pipe 410. After the screening of the quartz sand is completed, by opening the valve on the drainage pipe 410, the water and impurities inside the water tank 401 flow out through the drainage pipe 410.
[0030] Working principle: When screening old quartz sand, the quartz sand is poured into the interior of the screening bin 1. The quartz sand is located above the screening plate 2. The impurities in the quartz sand are screened through the screening holes on the screening plate 2. By controlling the switch of the hydraulic rod 302, the fixing ring 301 enables the hydraulic rod 302 to be installed on the support plate 3, providing a supporting effect on the above structure. At this time, the output end of the hydraulic rod 302 drives the connecting rod 305 to move. Turn on the external power switch of the drive motor 304. Then, the output shaft of the drive motor 304 drives the connecting rod 305 to rotate. The drive motor 304 is installed inside the protection box 303, which protects the drive motor 304 and prevents it from being damaged due to being exposed. Further, the connecting rod 305 drives multiple stirring rods 306 and multiple stirring plates 307 to rotate. The rotating multiple stirring rods 306 and multiple stirring plates 307 stir the quartz sand inside the screening bin 1, preventing the quartz sand from piling up together, accelerating the falling of particles, enabling fine particles to quickly pass through the screening plate 2. At the same time, control the up-and-down movement of the output end of the hydraulic rod 302, further causing the multiple stirring plates 307 to move up and down back and forth. When the multiple stirring plates 307 move up and down back and forth, they turn the quartz sand inside the screening bin 1 up and down, reducing the adhesion between particles, increasing the contact surface for screening, and contributing to the stratification of particles. Thus, when screening quartz sand, through stirring and turning, it accelerates the falling of particles, reduces the adhesion between particles, and improves the screening accuracy and efficiency; When screening quartz sand, multiple stirring rods 306 and multiple stirring plates 307 agitate the quartz sand inside the screening bin 1. At this time, turn on the external power switch of the bidirectional motor 211, and then the output shaft of the bidirectional motor 211 drives the threaded rod 202 to rotate. Since the sliding cylinder 205 can slide on the outer surface of the cross bar 204, the sliding cylinder 205 is connected to the scraper 210 through the sleeve 203, and the two sliding plates 206 can slide on both sides of the inner wall of the screening bin 1. Therefore, when the threaded rod 202 rotates in different directions, the sleeve 203 moves back and forth on the outer surface of the threaded rod 202. The two second telescopic rods 208 can slide inside the two first telescopic rods 207 respectively. The two springs 209 have elasticity, and the elasticity of the two springs 209 pushes the two second telescopic rods 208, further making one side of the scraper 210 closely adhere to one side of the screening plate 2. Control the output shaft of the bidirectional motor 211 to rotate back and forth, further making the sleeve 203 move back and forth on the outer surface of the threaded rod 202, and further driving the scraper 210 to move back and forth on one side of the screening plate 2. When sand or impurities block the screening holes on the screening plate 2, the moving back and forth scraper 210 will push the blocked impurities or sand, preventing the blockage of the screening holes of the screening plate 2 from affecting the screening efficiency. After screening, the impurities fall out of the inside of the screening bin 1 through the screening plate 2. The baffle 213 can slide on the inner wall of the groove plate 212. By pushing the push plate 214 to drive the baffle 213 to move, the baffle 213 is removed from the groove plate 212. At this time, the baffle 213 does not block the discharge port on the screening bin 1, and the quartz sand on the screening plate 2 can be scraped out of the inside of the screening bin 1. Therefore, when using the device, it is possible to prevent the screening holes on the screening plate 2 from being blocked, affecting the screening efficiency of the quartz sand, and further improving the screening effect of the device; When screening quartz sand, water is poured into the interior of the water tank 401. By turning on the external power switch of the delivery pump 405, suction is generated at the input end of the delivery pump 405. Further, the water inside the water tank 401 is sucked in through the first conduit 402. Under the action of the delivery pump 405, it is discharged into the interiors of two second conduits 407 through the two ports of the Y-shaped pipe 406, and further into the interiors of two hollow cylinders 408. Water is sprayed onto the interior of the screening bin 1 through a plurality of spray heads 409, and further onto the quartz sand, suppressing the generation of dust during the screening of quartz sand. At the same time, it can increase the lubricity of the particles, reduce the friction between the particles. The impurities and water fall through the screening holes on the screening plate 2 to the lower part of the screening bin 1, and are guided into the interior of the water tank 401 through the inclined surface of the screening plate 2 for secondary utilization. Moreover, the first conduit 402 sucks the water inside the water tank 401 through the suction head 403, and the impurities in the water can be filtered through the partition net 404. The contact area between the suction head 403 and the water is increased through the suction head 403. After the screening of the quartz sand is completed, by opening the valve on the drain pipe 410, the water and impurities inside the water tank 401 flow out through the drain pipe 410. Thus, when the device screens quartz sand, water is sprayed to suppress the generation of dust during the screening of quartz sand. At the same time, it can increase the lubricity of the particles, reduce the friction between the particles, improve the practicability of the device. At the same time, the water can be reused multiple times, saving resources.
