For example, the gap between the screening components of some devices is fixed and cannot be adjusted according to the particle size of the quartz sand raw material, so that particles that are too large or too small cannot be effectively processed, which affects the purification accuracy. Therefore, a high-temperature activation purification device for electronic grade quartz sand is proposed. Summary of the Invention

[0011] Preferably, the blower mechanism includes a servo motor, a protective shell is fixedly connected to one side of the purification box, a rotating shaft is fixedly connected to the output end of the servo motor, and the rotating shaft extends into the interior of the protective shell.

[0012] Preferably, both the protective shell and the purification box are provided with a rotating groove, the rotating shaft extends into the interior of the protective shell through the rotating groove, and the rotating shaft is rotatably connected to the protective shell and the purification box through the rotating groove.

[0013] Preferably, one side of the purification box has multiple ventilation holes inside the protective shell, and the ventilation holes are equipped with one-way valves that allow only inflow and no outflow. An L-shaped plate is fixedly connected to the side of the protective shell away from the purification box. The servo motor is fixed to the protective shell through the L-shaped plate. An air inlet hole is provided on the outer wall of the protective shell.

[0014] Preferably, the plurality of drive shafts are rotatably connected to the feed tube, and one end of the drive shaft is rotatably connected to the fixed circular block. The end of the drive shaft away from the fixed circular block extends to the outside of the feed tube. The plurality of drive shafts are connected to the rotating shaft by a drive belt.

[0015] Preferably, a circular groove is provided on one side of the feeding tube, the fixed circular block is located in the circular groove, and the diameter of the fixed circular block is smaller than the diameter of the circular groove. The sliding rod slides to the outside of the feeding tube through the gap between the outer wall of the fixed circular block and the inner wall of the circular groove, and the outer diameter of the sliding rod is smaller than the gap between the outer wall of the fixed circular block and the inner wall of the circular groove.

[0018] Preferably, the purification box is provided with a sliding groove, the sliding mesh plate is slidably connected to the purification box through the sliding groove, and the inner wall of the purification box is provided with an insertion groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In the stirring and screening mechanism of this invention, the transmission shaft drives the elastic element to rotate. By pulling or pushing the sliding rod, the gap between the two elastic elements can be flexibly adjusted. During the falling process of the quartz sand raw material, the quartz sand raw material larger than the gap is left above the elastic element, while the raw material smaller than the gap passes through. This achieves the initial screening of the quartz sand raw material, removing larger particle impurities. At the same time, the rotation of the elastic element stirs and disperses the passing quartz sand raw material, making the raw material distribution more uniform, providing good conditions for subsequent purification processes, and improving the purification effect.

[0022] When it is necessary to adjust the gap of the elastic component, the operation is simple and convenient. Pull the sliding rod to the outside of the feed tube downwards, which will drive the sliding ring and the elastic component, making the bending degree of the elastic component smaller and the gap smaller. Press down on the rotating plate located on the outside of the feed tube, and then slide the sliding rod inwards to make the gap larger. The design of the rotating plate, the fixed round block and the feed tube can effectively limit the sliding rod after it is adjusted to the appropriate position, ensuring the stable operation of the mixing and screening mechanism and improving the reliability and convenience of the equipment.

[0023] The servo motor in the blower mechanism of this invention drives the rotating shaft to rotate, which in turn drives the blower to rotate, generating airflow to blow and diffuse the quartz sand raw material falling inside the purification chamber. This helps to make the quartz sand raw material more evenly distributed in the purification chamber, increases the contact area between the raw material and the high-temperature environment, improves the efficiency of high-temperature activation and purification, makes the purification process more thorough, and further improves the purity of the quartz sand.

[0024] The sliding mesh plate in the placement mechanism of this invention can slide inside the purification chamber to place the flat and dispersed quartz sand raw material. The flat placement method allows the quartz sand raw material to be fully exposed to the high temperature environment, ensuring that each part of the raw material can receive uniform high temperature activation treatment, further improving the purification quality and meeting the strict requirements of electronic grade quartz sand for high purity.

[0033] 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.

[0034] Example 1

[0035] like Figure 1-7 As shown, a high-temperature activation and purification device for electronic-grade quartz sand includes:

[0036] Purification box 1, with a feeding pipe 2 fixedly connected to the top of purification box 1. The feeding pipe 2 is connected to the interior of purification box 1. A collection box 5 is fixedly connected to the top of purification box 1 on one side of the feeding pipe 2. One side of the collection box 5 is fitted to the outside of the feeding pipe 2.

[0037] like Figure 1-7 As shown, a blower mechanism is used to blow and diffuse the quartz sand raw material falling inside the purification box 1. The blower mechanism is located on one side of the outer wall of the purification box 1. The blower mechanism includes a servo motor 3. A protective shell 302 is fixedly connected to one side of the purification box 1. A rotating shaft 301 is fixedly connected to the output end of the servo motor 3, and the rotating shaft 301 extends into the protective shell 302. The end of the rotating shaft 301 away from the servo motor 3 is rotatably connected to the outer wall of the purification box 1. A blower fan 303 is fixedly connected to the outer wall of the rotating shaft 301 inside the protective shell 302.

[0038] The present invention is further described in detail as follows: both the protective shell 302 and the purification box 1 are provided with rotating grooves. The rotating shaft 301 extends into the interior of the protective shell 302 through the rotating grooves, and the rotating shaft 301 is rotatably connected to the protective shell 302 and the purification box 1 through the rotating grooves. A plurality of ventilation holes are provided on one side of the purification box 1 inside the protective shell 302, and a one-way valve that allows only inflow and outflow is provided inside the ventilation holes. An L-shaped plate is fixedly connected to the side of the protective shell 302 away from the purification box 1. The servo motor 3 is fixed to the protective shell 302 through the L-shaped plate. An air inlet hole is provided on the outer wall of the protective shell 302.

[0039] As can be seen from the above, the blower mechanism is located on one side of the outer wall of the purification box 1. The servo motor 3 is fixed on the protective shell 302 by the L-shaped plate. After the servo motor 3 is started, its output end drives the rotating shaft 301 to rotate. The rotating shaft 301 extends into the protective shell 302 through the rotating groove on the purification box 1 and is rotatably connected to the outer wall of the purification box 1. Multiple transmission shafts 4 are connected to the rotating shaft 301 through the transmission belt. Therefore, when the rotating shaft 301 rotates, it will drive the transmission shaft 4 to rotate.

[0040] The outer wall of the rotating shaft 301 is fixedly connected to the blower 303 inside the protective shell 302. The rotation of the rotating shaft 301 drives the blower 303 to rotate, generating airflow. Outside air enters the interior of the protective shell 302 through the air inlet on the outer wall of the protective shell 302. One-way valves that allow air to enter but not exit are installed in multiple ventilation holes on one side of the purification box 1 inside the protective shell 302. The airflow enters the interior of the purification box 1 through the ventilation holes, blowing and diffusing the quartz sand raw material that falls on the placement mechanism inside the purification box 1, so that the raw material can fully contact the surrounding environment in a high-temperature environment, thereby improving the purification effect.

[0041] With the above technical solution, the servo motor 3 in the blower mechanism drives the rotating shaft 301 to rotate, which in turn drives the blower 303 to rotate, generating wind to blow and diffuse the quartz sand raw material falling into the purification box 1. This helps to make the quartz sand raw material more evenly distributed in the purification box 1, increase the contact area between the raw material and the high temperature environment, improve the efficiency of high temperature activation and purification, make the purification process more thorough, and further improve the purity of the quartz sand.

[0042] Multiple ventilation holes with one-way valves are set in the protective shell 302 on one side of the purification box 1, and air inlets are set in the outer wall of the protective shell 302 to form a reasonable air path system. The one-way valves ensure that air can only enter the purification box 1, prevent the gas inside the box from flowing back, maintain a stable airflow environment inside the purification box 1, which is conducive to the stable operation of the blower mechanism and ensures the purification effect.

[0043] Example 2

[0044] like Figure 1-7 As shown, a stirring and screening mechanism is added based on the above embodiment 1 to stir, disperse and purify the quartz sand raw material entering the purification box 1. The stirring and screening mechanism is located above the purification box 1. The stirring and screening mechanism includes a drive shaft 4 and an elastic element 402. The outer wall of the drive shaft 4 is fixedly connected to a first fixed ring 401 and a second fixed ring 4010 inside the feed pipe 2. The outer wall of the drive shaft 4 is slidably connected to a sliding ring 403. A sliding rod 404 is fixedly connected to one side of the sliding ring 403. Multiple mounting slots are opened on the outer wall of the sliding rod 404. A rotating rod 408 is rotatably connected inside the mounting slot. A rotating clamping plate 405 is fixedly connected to the outer wall of the rotating rod 408. A compression spring 406 is fixedly connected to the outer wall of the sliding rod 404 next to the mounting slot. A mountain-shaped fixing plate 407 is fixedly connected to the outer wall of the feed pipe 2. Fixed round blocks 409 are fixedly connected to both ends of the mountain-shaped fixing plate 407.

[0045] The present invention is further described in detail as follows: multiple drive shafts 4 are rotatably connected to the feed tube 2, and one end of the drive shaft 4 is rotatably connected to the fixed circular block 409. The end of the drive shaft 4 away from the fixed circular block 409 extends to the outside of the feed tube 2. The multiple drive shafts 4 are connected to the rotating shaft 301 by a drive belt. A circular groove is opened on one side of the feed tube 2. The fixed circular block 409 is located in the circular groove, and the diameter of the fixed circular block 409 is smaller than the diameter of the circular groove. The sliding rod 404 slides to the outside of the feed tube 2 through the gap between the outer wall of the fixed circular block 409 and the inner wall of the circular groove. The outer diameter of the sliding rod 404 is smaller than the gap between the outer wall of the fixed circular block 409 and the inner wall of the circular groove. One end of the elastic member 402 is fixedly connected to the first fixed ring 401. The end of the elastic member 402 away from the first fixed ring 401 is slidably connected to the second fixed ring 4010 and slides to the sliding ring 403. The elastic member 402 and the sliding ring 403 are fixedly connected.

[0046] As can be seen from the above, the top of the purification box 1 is fixedly connected to the feed pipe 2, and the feed pipe 2 is connected to the inside of the purification box 1. The quartz sand raw material is poured in from above the feed pipe 2. Under the action of gravity, the raw material falls into the purification box 1 along the feed pipe 2.

[0047] The stirring and screening mechanism is located above the purification box 1. Its drive shaft 4 is rotatably connected to the feed pipe 2. One end is rotatably connected to the fixed round block 409, and the other end extends to the outside of the feed pipe 2. The outer wall of the drive shaft 4 is fixedly connected to the first fixed ring 401 and the second fixed ring 4010 inside the feed pipe 2. The outer wall is slidably connected to the sliding ring 403. The sliding rod 404 is fixedly connected to one side of the sliding ring 403. One end of the elastic element 402 is fixed to the first fixed ring 401, and the other end is slidably connected to the second fixed ring 4010 and slides onto the sliding ring 403 and is fixedly connected.

[0048] When it is necessary to reduce the gap between the two elastic components 402 to screen for finer impurities, the sliding rod 404 is pulled to move it to the outside of the feed tube 2. The sliding rod 404 drives the sliding ring 403 and the elastic component 402 to move. The bending degree of the elastic component 402 becomes smaller, and the gap between the two elastic components 402 becomes smaller. At this time, when the rotating plate 405 in the mounting groove on the outer wall of the sliding rod 404 contacts the inner wall of the feed tube 2, it retracts to one side of the sliding rod 404 according to the rotation action of the rotating rod 408, and slides outward through the gap between the outer wall of the fixed round block 409 and the inner wall of the round groove. When the rotating plate 405 is located on the outer wall of the feed tube 2, according to the action of the compression spring 406, the rotating plate 405 returns to the initial position, with one side attached to the outer wall of the feed tube 2, limiting the sliding rod 404 and keeping the elastic component 402 in the reduced gap state.

[0049] When it is necessary to increase the gap between the two elastic components 402, press down on the rotating plate 405 located on the outside of the feed tube 2 to release the limit on the sliding rod 404, and then slide the sliding rod 404 to the inside of the feed tube 2 to drive the sliding ring 403 and the elastic component 402 to move, so that the bending degree of the elastic component 402 increases and the gap between the two elastic components 402 increases.

[0050] During the falling process of the quartz sand raw material, the drive shaft 4 rotates, and the source of its rotational power will be explained later. It drives the first fixed ring 401, the second fixed ring 4010, the sliding ring 403, and the elastic element 402 to rotate together. During the rotation, the elastic element 402 stirs and disperses the falling quartz sand raw material. At the same time, since there is a gap between the two elastic elements 402, the quartz sand raw material or impurities larger than the gap will remain above the elastic element 402, while the raw material smaller than the gap will continue to fall into the purification box 1, thus achieving the initial screening of the quartz sand raw material.

[0051] With the above technical solution, the transmission shaft 4 in the stirring and screening mechanism drives the elastic element 402 to rotate. By pulling or pushing the sliding rod 404, the gap between the two elastic elements 402 can be flexibly adjusted. During the falling of the quartz sand raw material, the quartz sand raw material larger than the gap is left above the elastic element 402, while the raw material smaller than the gap passes through, thus achieving the initial screening of the quartz sand raw material and removing larger particle impurities. At the same time, the rotation of the elastic element 402 stirs and disperses the passing quartz sand raw material, making the raw material distribution more uniform, providing good conditions for the subsequent purification process and improving the purification effect.

[0052] When it is necessary to adjust the gap of the elastic element 402, the operation is simple and convenient. Pull the sliding rod 404 to the outside of the feed tube 2, which will drive the sliding ring 403 and the elastic element 402, so that the bending degree of the elastic element 402 is reduced and the gap is reduced. Press down on the rotating plate 405 located on the outside of the feed tube 2, and then slide the sliding rod 404 inward to increase the gap. The cooperation design of the rotating plate 405 with the fixed round block 409 and the feed tube 2 can effectively limit the sliding rod 404 after it is adjusted to the appropriate position, ensuring the stable operation of the mixing and screening mechanism and improving the reliability and convenience of the equipment.

[0053] Multiple drive shafts 4 are connected to the rotating shaft 301 via drive belts, enabling a single power source servo motor 3 to simultaneously drive the stirring and screening mechanism and the blowing mechanism. This design simplifies the equipment structure, reduces the number of power equipment, and lowers equipment costs and energy consumption. At the same time, unified transmission control allows the stirring and screening and blowing processes to work together better, and the operating parameters can be adjusted according to actual production needs to improve the overall performance and production efficiency of the equipment.

[0054] Example 3

[0055] like Figure 1-7 As shown, a placement mechanism is added based on the above embodiment 2 to place and spread the quartz sand raw material that enters the purification box 1. The placement mechanism is slidably set inside the purification box 1. The placement mechanism includes a sliding mesh plate 6 that is slidably connected inside the purification box 1 to place and spread the quartz sand raw material that has been dispersed and entered into the purification box 1, so that it can be fully purified at high temperature. One end of the sliding mesh plate 6 is connected to a sealing plate 601, and a pull ring 602 is fixedly installed on one side of the sealing plate 601.

[0056] The present invention is further described in detail as follows: a sliding groove is provided on the purification box 1, and the sliding mesh plate 6 is slidably connected to the purification box 1 through the sliding groove. An insertion groove is provided on the inner wall of the purification box 1. The sliding mesh plate 6 and the insertion groove are slidably inserted into each other. The size of the sealing plate 601 is larger than the size of the sliding groove, and the sealing plate 601 and the sliding groove are fitted together.

[0057] As can be seen from the above, the placement mechanism is slidably set inside the purification box 1. The sliding screen plate 6 is slidably connected to the purification box 1 through the sliding groove on the purification box 1, and is slidably inserted into the insertion groove on the inner wall of the purification box 1. After the quartz sand raw material passes through the stirring and screening mechanism, it falls onto the sliding screen plate 6. The sliding screen plate 6 places the quartz sand raw material flat, so that it can be evenly heated in the purification box 1 to achieve sufficient high-temperature purification. After purification, the sealing plate 601 and the sliding screen plate 6 can be slid outward along the sliding groove and the insertion groove by pulling the pull ring 602 on one side of the sealing plate 601, so that the sealing plate 601 and the sliding screen plate 6 can be taken out. The size of the sealing plate 601 is larger than the size of the sliding groove and is set in close contact with the sliding groove. It plays a sealing role in the purification process to prevent heat loss and external impurities from entering the purification box 1 and affecting the purification effect.

[0058] With the above technical solution, the sliding mesh plate 6 in the placement mechanism can slide in the purification box 1 to place the flat and dispersed quartz sand raw material. The flat laying method allows the quartz sand raw material to be fully exposed to the high temperature environment, ensuring that each part of the raw material can receive uniform high temperature activation treatment, further improving the purification quality and meeting the strict requirements of electronic grade quartz sand for high purity.

[0059] The sealing plate 601 connected to one end of the sliding screen plate 6 is larger than the size of the sliding groove on the purification box 1 and is fitted to fit the sliding groove. After the sliding screen plate 6 is inserted into the purification box 1, the sealing plate 601 can effectively seal the sliding groove, prevent the leakage of high-temperature gas in the purification box 1, ensure the stability of the purification environment, reduce heat loss, and reduce energy consumption. The pull ring 602 is designed to make it easy for operators to pull the sliding screen plate 6, which facilitates the handling of quartz sand raw materials and improves the convenience and safety of production operations.
