Description

Technical Field

[0001] This utility model relates to the field of silica processing equipment, specifically to a silica purification device. Background Technology

[0002] Silica is an important inorganic non-metallic material that is widely used in semiconductors, photovoltaics, optical glass, ceramics, catalysts and high-end chemicals. In the preparation of silica, it is necessary to purify it. For example, a silica purification device is disclosed in the publication document with announcement number CN222076862U.

[0003] However, there are certain limitations in the use of this device. Since the permanent magnet is always magnetic, the magnetic cylinder will always be magnetic. When the scraper scrapes the magnetic impurities off the magnetic cylinder, some of the magnetic impurities are close to the magnetic cylinder and are easily attracted back by the magnetic cylinder, resulting in poor scraping effect of the scraper. Utility Model Content

[0004] The purpose of this invention is to provide a silica purification device that overcomes certain limitations in the use of existing purification devices.

[0005] The present invention achieves the above objectives through the following technical solution: a silica purification device, comprising: a purification box and a grinding assembly disposed above the purification box;

[0006] The purification chamber is equipped with a magnetic cylinder and a drive device for driving the magnetic cylinder to rotate. The magnetic cylinder is equipped with an adjustable magnetic component.

[0007] The purification box has a waste outlet on its side wall and a scraper inside the purification box. The scraper is used to scrape off the magnetic impurities on the outer wall of the magnetic cylinder and guide them to the waste outlet. The purification box has a discharge port.

[0008] The adjusting magnetic component is used to cut off the magnetism of the magnetic cylinder located on the side above the scraper.

[0009] Preferably, the adjusting magnetic component includes an electromagnet, a touch switch, a pressing block, and a bracket. There are several electromagnets arranged in a ring on the inner wall of the magnetic cylinder. There are several touch switches, each corresponding to one of the electromagnets. The bracket is located on the purification box and extends into the magnetic cylinder. The pressing block is arc-shaped and is located on the bracket and fits against the touch switch.

[0010] Preferably, the grinding assembly includes a housing, two grinding rollers disposed within the housing, and a drive motor for driving the grinding rollers to rotate.

[0011] Preferably, the purification chamber is provided with guide plates located below the two grinding rollers, and a guide channel is formed between the two guide plates, the guide channel being inclined to the side away from the scraper.

[0012] Preferably, the purification box is equipped with a turning component.

[0013] Preferably, the bottom of the inner cavity of the purification box is provided with a tray and a drive component for driving the tray to rise and fall.

[0014] Preferably, the purification chamber is equipped with a detector, and the drive unit is used to stop working when the detector detects that the pallet has reached a predetermined height.

[0015] Preferably, the purification chamber is provided with a protective cover for covering the detector, the bottom of the protective cover has an opening, and a transparent plate is provided in the opening.

[0016] The beneficial effects of this utility model are as follows: by adjusting the magnetic components, the magnetism of the magnetic cylinder located on the side above the scraper disappears, so that the magnetic impurities in this area are not affected by the magnetic force. The magnetic impurities fall to the top of the scraper under the action of gravity, and the scraper can also scrape off the magnetic impurities in this area. At the same time, the magnetic impurities on the scraper will no longer be attracted by the magnetic cylinder, which improves the cleaning effect of magnetic impurities, avoids the accumulation of magnetic impurities on the outer wall of the magnetic cylinder, ensures the magnetic cylinder's adsorption capacity for magnetic impurities in silica particles, and improves the purification effect of silica.

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] Please see Figure 1 and Figure 2 A silica purification device includes: a purification chamber 1, with a grinding assembly 2 on the top of the purification chamber 1; a magnetic cylinder 8 (which may be made of plastic and has a thin inner wall to reduce the influence on the magnetic field) is rotatably installed in the inner cavity of the purification chamber 1; a driving device (such as a motor) is installed on the purification chamber 1, and the output shaft of the driving device is connected to the magnetic cylinder 8 to drive the magnetic cylinder 8 to rotate around its own axis; an adjusting magnetic component 9 is provided inside the magnetic cylinder 8; a waste outlet 3 is opened in the middle of the left side wall of the purification chamber 1; a scraper 10 is provided in the inner cavity of the purification chamber 1; the right side wall of the scraper 10 is attached to the left side wall of the magnetic cylinder 8; the top of the left side wall of the scraper 10 is flush with the waste outlet 3; a discharge port 4 is opened in the bottom right side wall of the purification chamber 1; the discharge port 4 is sealed by a cover plate; during discharge, the cover plate is removed and the discharge port 4 is opened.

[0025] Working principle: Silica particles are poured into the grinding assembly 2, which grinds the silica particles. The ground silica particles enter the purification chamber 1. Magnetic impurities in the silica particles are attracted to the outer surface of the magnetic cylinder 8 by the adjusting magnetic component 9, while the silica particles fall directly into the inner cavity of the purification chamber 1. The drive device rotates the magnetic cylinder 8 counterclockwise. The adjusting magnetic component 9 controls the magnetism of the magnetic cylinder 8 located above the scraper 10 to disappear, causing the magnetic impurities in this area to lose their magnetic attraction. Under the action of gravity, the magnetic impurities fall above the scraper 10, and the scraper 10 also scrapes off the magnetic impurities in this area. The magnetic impurities are discharged through the waste outlet 3. The operation is repeated. The rotating magnetic cylinder 8 can also attract magnetic impurities in the silica particles at the bottom of the inner cavity of the purification chamber 1 again. After purification, the silica particles inside the purification chamber 1 are discharged from the discharge port 4.

[0026] It should be noted that the adjusting magnetic component 9 can be several electromagnets, which are installed on the inner wall of the magnetic cylinder 8. The rotation of the magnetic cylinder 8 causes the electromagnets to rotate. When the electromagnets move above one side of the scraper 10, the power will be cut off. After passing the scraper 10, the electromagnets will be powered on. The adjusting magnetic component 9 can also be the electromagnet 901, the touch switch 902, the pressing block 903 and the bracket 904 mentioned below.

[0027] In this embodiment, as a further optimization, please refer to... Figure 2The grinding assembly 2 includes a housing 201, two grinding rollers 202 rotatably disposed inside the housing 201, and a drive motor. The output shaft of the drive motor is connected to the shaft of the grinding rollers 202 to drive the grinding rollers 202 to rotate. The housing 201 is installed on the top wall of the purification box 1.

[0028] In this embodiment, as a further optimization, please refer to... Figure 2 The purification chamber 1 has two guide plates 203 inside. The tops of the two guide plates 203 are located below the two grinding rollers 202 respectively. A guide channel is formed between the two guide plates 203. The guide channel is inclined to the side away from the scraper 10. The two guide plates 203 guide the ground silica particles to prevent them from falling directly above the scraper 10 and causing the silica to be discharged, thus avoiding waste of resources.

[0029] Example 2

[0030] The following is a detailed description using a specific embodiment where the adjusting magnetic component 9 consists of an electromagnet 901, a touch switch 902, a pressing block 903, and a bracket 904:

[0031] Please see Figure 2 and Figure 3 The adjusting magnetic component 9 includes an electromagnet 901, a touch switch 902, a pressing block 903, and a bracket 904. There are several electromagnets 901 arranged in a ring and spaced apart on the inner wall of the magnetic cylinder 8. There are several touch switches 902, each corresponding to one of the electromagnets 901. Each electromagnet 901 is equipped with a touch switch 902 (and each electromagnet 901 is equipped with a power supply; the power supply, touch switch 902, and electromagnet 901 are connected in series). The bracket 904 is mounted on the purification box 1 and extends through an opening along the axis of the magnetic cylinder 8 into the inner cavity of the magnetic cylinder 8 (the bracket 904 is unaffected when the magnetic cylinder 8 rotates). The pressing block 903 is arc-shaped. 03 is mounted on the bracket 904 and is in contact with the touch switch 902. The touch switch 902 located above one side of the scraper 10 does not contact the pressing block 903, and the electromagnet 901 corresponding to the touch switch 902 is not energized here. When the magnetic cylinder 8 rotates, the electromagnet 901 and the touch switch 902 are rotated together, while the pressing block 903 does not move. When the touch switch 902 moves to one side above the scraper 10, the touch switch 902 and the pressing block 903 are not in contact, so the electromagnet 901 here is de-energized. When the touch switch 902 passes the scraper 10, it will contact the pressing block 903 again, so that the corresponding electromagnet 901 is energized and generates magnetic force, so that the magnetic cylinder 8 located above one side of the scraper 10 has no magnetic force.

[0032] Example 3

[0033] As a further optimization of Example 1, please refer to Figure 2 The purification chamber 1 is equipped with a turning assembly 7, which includes blades and a motor. The motor is mounted on the purification chamber 1, and the blades are mounted on the output shaft of the motor. The blades are located in the inner cavity of the purification chamber 1. The motor drives the blades to rotate, which is used to turn the silica particles at the bottom of the inner cavity of the purification chamber 1, so that the magnetic cylinder 8 can fully adsorb the magnetic impurities remaining in the silica at the bottom of the inner cavity of the purification chamber 1.

[0034] In this embodiment, as a further optimization, please refer to... Figure 2 The bottom of the inner cavity of the purification box 1 is provided with a tray 5, and the bottom of the purification box 1 is provided with a driving component 6 (such as an electric telescopic rod). The moving end of the driving component 6 is connected to the tray 5 and is used to drive the tray 5 to rise and fall. The tray 5 is driven to move upward by the driving component 6, so that the tray 5 carries the silica particles at the bottom of the inner cavity of the purification box 1 close to the magnetic cylinder 8, reducing the distance between the silica particles and the magnetic cylinder 8, ensuring that the magnetic cylinder 8 can fully adsorb magnetic debris, and ensuring the quality of silica purification.

[0035] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 4 The purification chamber 1 is equipped with a detector 11 (such as an infrared sensor) located above the tray 5. The purification chamber 1 is also equipped with a PLC controller. The detector 11 detects the distance between itself and the tray 5 or the silica particles above the tray 5. When the distance is less than a preset value, the PLC controller controls the drive unit 6 to stop working to prevent the silica particles above the tray 5 from being squeezed into the magnetic cylinder 8.

[0036] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 4 The purification chamber 1 has a protective cover 12 inside, which covers the detector and protects the detector 11. The bottom of the protective cover 12 has an opening, and a transparent plate 13 (such as a glass plate) is provided inside the opening to ensure that the detector 11 is not blocked from detection by the protective cover 12.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
