Description

Technical Field

[0001] This utility model relates to the field of quartz sand impurity removal technology, and in particular to a high-efficiency quartz sand electrostatic separation device. Background Technology

[0002] During the production and processing of quartz sand, it is easy for it to contain metal particles, which usually requires impurity removal and purification. Currently, the conventional impurity removal and purification is accomplished by electrostatic separation technology. It mainly utilizes the difference in electrical properties of materials in a high-voltage electric field to achieve the separation purpose. When the material passes through the high-voltage electric field of the rotating drum and electrodes, the material is subjected to various electric forces, centrifugal forces, and gravity. Due to the different electrical properties of various materials, the different force states cause the materials to fall in different trajectories, thereby separating quartz sand from metal particles.

[0003] Currently, when quartz sand is electrostatically separated, quartz sand and metal particles slide out from both sides of the two separator plates. However, some of the mixture of quartz sand and metal particles is difficult to separate and is output between the two separator plates, resulting in poor separation effect. Usually, this mixture needs to be collected manually and put back into the device for separation, which is quite troublesome.

[0004] To address these issues, we propose a high-efficiency electrostatic separation device for quartz sand. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency electrostatic separation device for quartz sand to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency electrostatic quartz sand separator includes a machine body and a sorting drum, an electrode plate, a waste material outlet, a mixed material outlet, a pure material outlet, and a discharge brush roller installed inside the machine body. The sorting drum and the discharge brush roller are rotatably connected to the machine body, and the pure material outlet is located below the discharge brush roller. The electrode plate is located around the sorting drum, and the waste material outlet is located below the electrode plate. The mixed material outlet is located between the waste material outlet and the pure material outlet.

[0008] The machine body is provided with a feeding guide plate, and an elevator cylinder is installed outside the machine body. The bottom side of the elevator cylinder is connected to the mixing outlet, and a return guide plate is installed between the top side of the elevator cylinder and the feeding guide plate. A auger shaft is rotatably installed inside the elevator cylinder, and a motor for driving the auger shaft to rotate is installed at the top of the elevator cylinder.

[0009] In a further embodiment, a clamp is also installed between the middle section of the lifting cylinder and the machine body.

[0010] In a further embodiment, a reciprocating screw is rotatably mounted on the feed guide plate. A sliding sleeve is fitted around the reciprocating screw, and a feeding claw is installed under the sliding sleeve via a connecting rod. One end of the reciprocating screw is connected to a second motor.

[0011] In a further embodiment, the feed guide plate is also provided with a slide rod parallel to the reciprocating screw, which slides through the interior of the sleeve.

[0012] In a further embodiment, the feeding claw and the connecting rod are threaded together.

[0013] In a further embodiment, the discharge end of the waste material outlet extends through the right side of the machine body.

[0014] In a further embodiment, the discharge end of the pure material outlet extends through the bottom surface of the machine body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a lifting cylinder connected between the mixing outlet and the infeed guide plate. This allows the mixture of quartz sand and metal particles that falls into the mixing outlet to be lifted by the lifting cylinder to the infeed guide plate and then reintroduced into the device for sorting. This enables continuous and multiple sorting operations on the mixture, effectively improving the separation of impurities in the quartz sand and eliminating the hassle of repeated manual refeeding.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 A high-efficiency electrostatic quartz sand separation device includes a body 1 and a separation roller 2, an electrode plate 3, a waste material outlet 4, a mixed material outlet 5, a pure material outlet 6, and a discharge brush roller 7 installed inside the body 1. The separation roller 2 and the discharge brush roller 7 are rotatably connected to the body 1. The discharge brush roller 7 is located at the lower left corner of the separation roller 2. The pure material outlet 6 is located below the discharge brush roller 7, and its discharge end extends through the bottom surface of the body 1 for easy... Quartz sand particles are discharged from the bottom of the machine body 1. The electrode plate 3 is located on the outer periphery of the upper right corner of the sorting drum 2, and the impurity discharge port 4 is located below the electrode plate 3. The discharge end of the impurity discharge port 4 extends through the right side of the machine body 1, so as to facilitate the discharge of metal particles from the side of the machine body 1. The mixed material discharge port 5 is located between the impurity discharge port 4 and the pure material discharge port 6. The discharge end of the mixed material discharge port 5 extends through the back of the machine body 1, so as to facilitate the discharge of the mixture of quartz sand and metal particles from the back of the machine body 1.

[0027] Please see Figure 1-4 To facilitate the re-sorting of the mixture, a vertical lifting cylinder 9 is installed outside the machine body 1. The machine body 1 is equipped with a feed guide plate 8, which is inclined towards the sorting drum 2 to facilitate feeding material into the sorting drum 2. The bottom side of the lifting cylinder 9 is connected to the discharge end of the mixture outlet 5, and the top side of the lifting cylinder 9 is equipped with a return guide plate 10. The return guide plate 10 is mounted on the feed guide plate 8 and is inclined inward towards the feed guide plate 8. A auger shaft 11 is rotatably installed inside the lifting cylinder 9, and a motor 12 is installed at the top of the lifting cylinder 9 to drive the auger shaft 11 to rotate. This allows the mixture to be lifted back into the feed guide plate 8 under the drive of the rotating auger shaft 11, thereby realizing continuous and multiple sorting operations of the mixture and improving the thoroughness of impurity removal from the quartz sand.

[0028] For further details, please refer to Figure 2 In order to improve the stability of the lifting cylinder 9, a clamp 17 is also installed between the middle section of the lifting cylinder 9 and the machine body 1.

[0029] Please see Figure 5 Considering that the quartz sand mixture on the feed guide plate 8 is too concentrated during feeding, which can easily affect the separation effect and lead to excessive mixing, a reciprocating screw 15 is rotatably installed on the feed guide plate 8. The reciprocating screw 15 is parallel to the width direction of the feed guide plate 8. A sliding sleeve 132 is sleeved around the reciprocating screw 15. A sliding pin is provided in the sliding sleeve 132 and slides in cooperation with the spiral groove of the reciprocating screw 15. A material-pulling claw 13 is installed under the sliding sleeve 132 through the connecting rod 131. One end of the reciprocating screw 15 is connected to a motor 16. When the reciprocating screw 15 rotates, the sliding sleeve 132 slides in the spiral groove of the reciprocating screw 15 through the sliding pin on it. The sliding sleeve 132 is driven to move axially back and forth along the reciprocating screw 15, which drives the material-pulling claw 13 to move back and forth, thereby moving the quartz sand mixture back and forth, promoting its dispersion and feeding, which is beneficial to improving the separation effect.

[0030] Furthermore, the feed guide plate 8 is also provided with a slide rod 14 parallel to the reciprocating screw 15. The slide rod 14 slides through the interior of the sleeve 132, so that the sleeve 132 slides along the slide rod 14 when it moves. The slide rod 14 limits the movement of the sleeve 132, effectively preventing the sleeve 132 from deflecting and improving its movement stability.

[0031] To facilitate disassembly and maintenance of the material feeding claw 13, the material feeding claw 13 and the connecting rod 131 are connected by a thread, making it easy to disassemble and assemble the material feeding claw 13.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
