Description

Technical Field

[0001] This utility model relates to the technical field of alumina processing equipment, and in particular to a high-purity alumina demagnetizing device for polishing. Background Technology

[0002] High-purity alumina particles are the core raw material for sapphire processing. The two are closely related in terms of chemical composition, processing technology, and application fields. The purity, particle size, and processing technology of high-purity alumina particles directly affect the quality of sapphire crystals. During the production process, some ferromagnetic impurities may be mixed into the alumina particles. These impurities will have an adverse effect on product quality and subsequent use. Therefore, demagnetization treatment is required. Alumina particles are commonly used in industries such as ceramics, refractory materials, and electronics, which have high requirements for material purity. Ferromagnetic impurities (such as iron filings and metal particles) reduce the purity of alumina and affect product performance. Demagnetization effectively removes these impurities, ensuring the chemical purity and physical properties of alumina granules. Ferromagnetic impurities in alumina granules can cause wear and tear on production equipment (such as grinding mills and conveying pipelines) as the material flows, shortening equipment lifespan. Ferromagnetic impurities may also form agglomerates or be unevenly distributed in alumina granules, affecting product uniformity and consistency. After demagnetization, the particle size distribution and properties of alumina granules are more stable, contributing to the production of high-quality products. Demagnetization of alumina granules is crucial for removing ferromagnetic impurities, ensuring product purity, equipment safety, product quality, and production efficiency, while also meeting the requirements of downstream processes. This step is essential in the production and application of alumina.

[0003] Currently, when demagnetizing alumina particles, the particles are poured into a tank and stirred. Iron filings and other impurities in the particles are then attracted by a pre-set magnetic strip, thus completing the demagnetization process. However, during operation, each feeding component can only correspond to a single channel of the demagnetization mechanism, which reduces the efficiency of this process and affects the overall processing efficiency, making it unsuitable for practical use.

[0004] Therefore, it is necessary to provide a high-purity alumina demagnetizing device for polishing to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the defects of the prior art, this utility model provides a high-purity alumina demagnetizing device for polishing. This solves the problem that in the existing device, the same feeding component can only correspond to a single channel of demagnetizing mechanism during operation, which leads to a decrease in efficiency in this process, and thus affects the overall processing efficiency, which is not conducive to practical use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-purity alumina demagnetizing device for polishing includes: a housing, a feed inlet, a processing mechanism, and a discharge box;

[0008] A feed inlet is installed in the center of the top surface of the box. The two sides of the feed inlet are connected to the two sides of the inside of the box. The front and rear ends of the feed inlet are integrally formed with the box to limit the movement of the granular material. Processing mechanisms are installed on both sides of the inside of the box. The initial ends of the processing mechanisms are the two sides of the inside of the box, and the discharge ends face the center of the inside of the box. A feeding box is installed below the discharge ends. The top and bottom surfaces of the feeding box are open.

[0009] In one embodiment, the processing mechanism comprises a buffer plate and a demagnetizing component. The buffer plate is inclined, with its high end connected to the inner wall of the box, and a demagnetizing component at its bottom. Multiple sets of demagnetizing components are arranged facing the inside of the box, forming a downward stepped arrangement. The other side of the lowest demagnetizing component is above the feeding box. The demagnetizing component is composed of a connecting plate, a mounting frame, a filter plate, a box body, and a magnet plate. The connecting plate is inclined, and a mounting frame is installed at the bottom right side of the connecting plate. A filter plate is horizontally connected to the inner top surface of the mounting frame. The diameter of the filter holes in the filter plate is smaller than the diameter of the material particles. The bottom of the mounting frame is sealed against the box body. A V-shaped opening is provided on the top surface of the box body, and a magnet plate is pre-installed inside the V-shaped opening.

[0010] In one embodiment, a guide platform is installed at the inner bottom of the feed inlet. The top surface of the guide platform has two arc-shaped sides, and the bottom ends of the two arc-shaped sides of the guide platform are at the same horizontal level as the middle section of the buffer plate.

[0011] In one embodiment, inspection doors are installed on the bottom of both outer sides of the box, and mounting components are installed inside the inspection doors. Each mounting component consists of a fixing frame and fixing rods. The fixing frame is installed and connected to the inner wall of the box by bolts. Fixing rods are installed on the top surfaces of both sides of the fixing frame. The fixing rods are installed and connected to the bottom surface of the box, and the height of the fixing rods is set according to the height of the box.

[0012] In one embodiment, a magnetic sheet is installed on the inner wall of the feeding box.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) This utility model sets up two sets of processing mechanisms with a single feed port. Only the granular material needs to be fed into the feed port, so that the material enters the processing mechanism along the limit path for demagnetization treatment, thereby improving work efficiency. The material particles are manually fed into the feed port and transported to the buffer plates on both sides through the guide table. When the material passes through the demagnetizing parts set in the stepped section, the material particles come into contact with the filter plate, causing the iron filings attached to them to fall off. The iron filings are then attracted by the magnetic plate through the holes of the filter plate. After the material particles have undergone multiple magnetic attraction treatments, the cleanliness of the material particles is improved, and the continuous processing method further improves work efficiency.

[0015] (2) This utility model places a sealing gasket between the top surface of the box and the bottom surface of the mounting frame to make the two fit tightly together. Then the fixing frame is installed inside the box. When it is necessary to clean the inside of the box, the inspection door is opened and the bolts of the fixing frame are released to remove multiple boxes, which improves the convenience of maintenance.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0022] like Figures 1-2 As shown, the present invention provides a high-purity alumina demagnetizing device for polishing, comprising: a housing 1, a feed inlet 2, a processing mechanism 3, and a discharge box 4;

[0023] like Figures 1-2As shown, a feed inlet 2 is installed in the middle of the top surface of the box 1. The two sides of the feed inlet 2 are connected to the two sides of the interior of the box 1. The front and rear ends of the feed inlet 2 are integrally formed with the box 1 to limit the movement of granular materials. Processing mechanisms 3 are installed on both sides of the interior of the box 1. The initial end of the processing mechanism 3 is the two sides of the interior of the box 1, and the discharge end faces the middle of the interior of the box 1. A feeding box 4 is installed below the discharge end. The top and bottom surfaces of the feeding box 4 are open. With the setting of two sets of processing mechanisms 3 corresponding to a single feed inlet 2, the granular materials only need to be fed into the feed inlet 2, so that the materials enter the processing mechanism 3 along the limiting path for demagnetization treatment, thereby improving work efficiency.

[0024] Preferably, in one embodiment, such as Figures 2-4 As shown, the processing mechanism 3 consists of a buffer plate 31 and a demagnetizing component 32. The buffer plate 31 is inclined, with its high end connected to the inner wall of the box 1, and the demagnetizing component 32 is installed at its bottom end. Multiple sets of the demagnetizing component 32 are arranged facing the inside of the box 1 in a downward stepped manner. The other side of the lowest demagnetizing component 32 is above the feeding box 4. The demagnetizing component 32 is composed of a connecting plate 33, a mounting frame 34, a filter plate 36, a box 36, and a magnet plate 37. The connecting plate 33 is inclined, and the mounting frame 34 is installed at the bottom right side of the connecting plate 33. The filter plate 36 is installed on the inner top surface of the mounting frame 34 and is horizontally connected to it. The diameter of the filter holes of the filter plate 36 is smaller than the diameter of the material particles. The bottom of the mounting frame 34 is sealed and abuts against the box 36. The top surface of the box 36 has a V-shaped opening, and the magnet plate 37 is pre-installed in the V-shaped opening.

[0025] Preferably, in one embodiment, such as Figures 1-3 As shown, a guide platform 21 is installed at the bottom of the feed inlet 2. The top surface of the guide platform 21 has an arc-shaped structure on both sides. The bottom of the arc-shaped surfaces on both sides of the guide platform 21 is at the same level as the middle section of the buffer plate 31. During operation, material particles are manually fed into the feed inlet 2 and transported to the buffer plates 31 on both sides through the guide platform 21. When the material passes through the demagnetizing components 32 set in the stepped section, the material particles come into contact with the filter plate 36, causing the iron filings attached to them to fall off. The iron filings are then attracted by the magnetic plate 37 through the holes of the filter plate 36. After the material particles have undergone multiple magnetic attraction treatments, the cleanliness of the material particles is improved, and the continuous treatment method further improves the work efficiency.

[0026] Preferably, in one embodiment, such as Figures 2-3As shown, inspection doors 11 are installed on the bottom of both outer sides of the housing 1. An installation component 5 is installed inside each inspection door 11. The installation component 5 consists of a fixing frame 51 and fixing rods 52. The fixing frame 51 is bolted to the inner wall of the housing 1. Fixing rods 52 are installed on the top surfaces of both sides of the fixing frame 41. The fixing rods 52 are connected to the bottom surface of the box 36. The height of the fixing rods 52 is matched to the height of the box 36. During operation, a sealing gasket is placed between the top surface of the box 36 and the bottom surface of the installation frame 34 to ensure a tight fit. Then, the fixing frame 51 is installed inside the housing 1. When cleaning the inside of the box 36 is required, the inspection door 11 is opened, and the bolts of the fixing frame 51 are released to remove multiple sets of boxes 36, improving the convenience of maintenance.

[0027] Preferably, in one embodiment, such as Figure 2 As shown, a magnetic sheet 41 is installed on the inner wall of the feeding box 4. The cleanliness of the material particles is further improved by setting the magnetic sheet 41.

[0028] Working principle of this utility model:

[0029] During operation, with a single feed inlet 2 corresponding to two sets of processing mechanisms 3, granular materials are simply fed into the feed inlet 2, allowing them to enter the processing mechanism 3 along the limiting path for demagnetization, thus improving work efficiency. Alternatively, granular materials can be manually fed into the feed inlet 2 and conveyed to the buffer plates 31 on both sides via the guide platform 21. When the material passes through the demagnetizing components 32 set in the stepped section, the granular materials come into contact with the filter plate 36, causing the attached iron filings to fall off. The iron filings are then attracted by the magnetic plate 37 through the holes in the filter plate 36. After the granular materials undergo multiple magnetic attraction processes, the cleanliness of the granular materials is improved. Furthermore, the continuous processing method further enhances work efficiency. By placing a sealing gasket between the top surface of the box 36 and the bottom surface of the mounting frame 34, the two are tightly fitted. Then, the fixing frame 51 is installed inside the box 1. When cleaning the inside of the box 36 is required, the inspection door 11 is opened, and the bolts of the fixing frame 51 are simply released to remove multiple sets of boxes 36, improving the convenience of maintenance.

[0030] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
