Description
Technical Field
[0001] This utility model relates to the field of quartz sand processing technology, and in particular to a 4N-grade high-purity quartz sand purification device. Background Technology
[0002] A search revealed that application number 202323622182.X discloses a multi-stage purification device for processing high-purity quartz sand, including a purification box and a screening component for multi-stage purification of quartz sand. The purification box includes an installation cavity on one side of the purification box to provide installation space, a purification cavity on the other side of the purification box for screening, a feeding rack on the top of the purification box for feeding materials, a plurality of first discharge racks evenly arranged at the other end of the purification box, and a second discharge rack at the bottom of the purification box.
[0003] The multi-stage purification device for high-purity quartz sand processing in this patent application uses a motor, cam, rollers, and sliding frame to drive three screening plates to vibrate. The material is then screened through screening holes on the three screening plates. However, in this process, because the three screening plates are equipped with guide strips to restrict the rolling of the material and improve the screening effect, the three screening plates are prone to material accumulation, requiring frequent cleaning and reducing the screening efficiency of the equipment. Therefore, we propose a 4N-grade high-purity quartz sand purification device. Utility Model Content
[0004] The present invention aims to solve the technical problems existing in the prior art and provide a 4N-grade high-purity quartz sand purification device.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a 4N-grade high-purity quartz sand purification device, comprising a purification chamber and a feeding rack disposed on the top left end of the purification chamber; a vibration mechanism is disposed at the bottom of the purification chamber, the vibration mechanism comprising an elastic support frame connected to the bottom end of the purification chamber by springs and a vibration motor fixedly installed in the middle of the bottom wall of the purification chamber; a filtration mechanism is disposed inside the purification chamber, the filtration mechanism comprising two filter conveyor belts disposed on the upper and lower sides of the inner cavity of the purification chamber and two sets of filter conveyor rollers connected inside the two filter conveyor belts. The two ends of the two sets of filter conveyor rollers are rotatably connected to the front and rear side walls of the inner cavity of the purification box, respectively. The right end of the purification box is fixedly fitted with two discharge channels corresponding to the right ends of the two filter conveyor belts. Two guide frames that penetrate the middle of the inner side of the two filter conveyor belts are fixedly connected in the inner cavity of the purification box. The front wall of the purification box is connected to two guide hoppers that correspond to the positions of the two guide frames. The bottom left of the two guide hoppers is provided with a discharge port. The discharge port of the guide hopper located in the upper position extends through the front wall of the purification box to the position above the left end of the filter conveyor belt located in the lower position.
[0006] Furthermore, the outer walls of the two filter conveyor belts are uniformly perforated with primary filter holes and secondary filter holes, respectively.
[0007] Furthermore, each of the two sets of filter transfer rollers is provided with four rollers arranged in a matrix.
[0008] Furthermore, two drive motors are fixedly installed on the left side of the rear wall of the purification chamber.
[0009] Furthermore, the output ends of the two drive motors extend into the cavity of the purification chamber and are respectively fixedly installed at the rear ends of the two filter conveyor rollers located on the upper left side of the inner side of the two filter conveyor belts.
[0010] Furthermore, the outer right walls of both filter conveyor belts are in contact with two guide plates that are fixedly connected to the bottom left of the two discharge channels.
[0011] Furthermore, two limiting baffles, which are fixedly connected to the inner cavity side wall of the purification box, are respectively installed on the upper left side of the outer wall of the two filter conveyor belts.
[0012] Furthermore, both of the aforementioned guide frames are U-shaped.
[0013] Furthermore, the bottom walls of the inner cavities of both guide frames are inclined in a manner that is lower in the front and higher in the back.
[0014] Furthermore, the front wall of the purification box is provided with two discharge ports that communicate with the front end of the inner cavity of the two guide racks, and the rear ends of the two guide hoppers are respectively connected to two discharge ports.
[0015] This invention provides a 4N-grade high-purity quartz sand purification device. It has the following beneficial effects:
[0016] 1. This 4N-grade high-purity quartz sand purification device, through the installation of a filtration mechanism, involves pouring the material through a feeding rack into the purification chamber's inner cavity, onto the top of the upper filter conveyor belt. The vibration motor and two drive motors are then activated. The vibration motor, in conjunction with the elastic support frame, drives the purification chamber to vibrate vertically. The purification chamber, in turn, drives the two filter conveyor belts to vibrate. The material undergoes a primary filtration operation through the filter holes of the upper filter conveyor belt, with smaller particles falling into the upper guide frame and moving forward along the inclined wall at the bottom of its inner cavity. These particles then pass through the upper outlet and guide hopper into the top of the lower filter conveyor belt, where a secondary filtration operation is performed through the filter holes of the lower filter conveyor belt. Again, smaller particles fall into the lower guide frame. The material moves forward along the inclined wall at the bottom of its inner cavity, and is then discharged and collected through the discharge port and guide hopper located at the bottom. Two drive motors drive the top of the two filter conveyor belts to slowly move to the right through two sets of filter conveyor rollers, moving the remaining material on the top of the two filter conveyor belts to the right to the edge position. Under the guidance of two guide plates, the material is discharged and collected through two discharge channels. This realizes the screening and purification operation of the equipment, and also ensures that there is no material retention on the two filter conveyor belts, so that no additional cleaning operation is required. The residence time of the material on the two filter conveyor belts can be controlled by adjusting the transmission speed of the two drive motors, so that the material can be fully screened and purified. The above operation is simple and practical, the structure is reasonable and compact, and the screening and purification effect and efficiency of the equipment are improved.
[0017] 2. This 4N-grade high-purity quartz sand purification device, by setting limiting baffles and guide inclined plates, the two limiting baffles can block the material located at the top of the two filter conveyor belts, so as to prevent the material from moving to the left and leaving the two filter conveyor belts during the vibrating screening process. The two guide inclined plates form a scraping effect by adhering to the outer wall of the right end of the two filter conveyor belts, which can clean the material adhering to the surface of the two filter conveyor belts, so that the material can be fully discharged through the two discharge channels, improving the practicality of the equipment.

Inside the filter conveyor belt 14, there are two sets of filter conveyor rollers 15. The two ends of the two sets of filter conveyor rollers 15 are rotatably connected to the front and rear side walls of the inner cavity of the purification chamber 10, respectively. Two discharge channels 17, corresponding to the right ends of the two filter conveyor belts 14, are fixedly fitted into the right end of the purification chamber 10. Two guide frames 20, penetrating the middle of the inner side of the two filter conveyor belts 14, are fixedly connected inside the purification chamber 10. Two guide hoppers 22, corresponding to the positions of the two guide frames 20, are connected to the front wall of the purification chamber 10. Each guide hopper 22 has a discharge port 21 at its bottom left position. The guide hopper at the upper position... The discharge port 21 of the hopper 22 extends through the front wall of the purification chamber 10 to the upper left end of the filter conveyor belt 14 located below. The outer walls of the two filter conveyor belts 14 are evenly perforated with primary and secondary filter holes. Four filter conveyor rollers 15 are arranged in a matrix on each of the two sets. Two drive motors 16 are fixedly installed on the left side of the rear wall of the purification chamber 10. The output ends of the two drive motors 16 extend into the inner cavity of the purification chamber 10 and are fixedly installed to the rear ends of the two filter conveyor rollers 15 located on the upper left side of the inner side of the two filter conveyor belts 14. The outer wall of the right end of the filter conveyor belt 14 is in contact with two guide plates 18 that are fixedly connected to the bottom left end of the two discharge channels 17. The upper left side of the outer wall of the two filter conveyor belts 14 is fitted with two limiting baffles 19 that are fixedly connected to the inner wall of the purification box 10.

Two drive motors 16 drive the tops of the two filter conveyor belts 14 slowly through two sets of filter conveyor rollers 15. The material is slowly conveyed to the right, moving the remaining material at the top of the two filter conveyor belts 14 to the edge. Guided by the two guide plates 18, it is then discharged through the two discharge channels 17 for collection. This process achieves the screening and purification of the material, ensuring no material remains on the two filter conveyor belts 14, eliminating the need for additional cleaning. The conveying speed of the two filter conveyor belts 14 can be adjusted by the two drive motors 16, thus controlling the residence time of the material on the two filter conveyor belts 14 and ensuring thorough screening and purification. The equipment is simple and practical to operate, with a reasonable and compact structure, which improves the screening and purification effect and efficiency of materials. The two limiting baffles 19 can block the material located at the top of the two filter conveyor belts 14 to prevent the material from moving to the left and detaching from the two filter conveyor belts 14 during the vibrating screening process. The two guide plates 18 form a scraping effect by adhering to the outer wall of the right end of the two filter conveyor belts 14, which can clean the material attached to the surface of the two filter conveyor belts 14, so that the material can be fully discharged through the two discharge channels 17, improving the practicality of the equipment.
