Description

Technical Field

[0001] This utility model relates to the field of purification equipment technology, specifically a silicon carbide powder purification device. Background Technology

[0002] Silicon carbide (SiC) powder, as a high-performance inorganic non-metallic material, is widely used in semiconductors, ceramics, abrasives and other fields. Its purity directly affects its performance and application effect. Silicon carbide powder purification equipment has emerged to remove impurities, and silicon carbide powder purification equipment includes physical purification and chemical purification.

[0003] However, existing silicon carbide powder purification devices often encounter problems during use. Due to the presence of magnetic impurities such as iron and its oxides in the silicon carbide powder, a magnetic separator is typically used to generate a strong magnetic field. Under the influence of the magnetic field, these impurities are adsorbed onto the surface of the separator, thus separating them from the silicon carbide powder. However, this method is prone to agglomeration of the silicon carbide powder when it is damp, statically charged, or contains impurities. The purification device struggles to de-agglomerate and level the silicon carbide powder, resulting in poor purification performance. Therefore, we propose a silicon carbide powder purification device. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides a silicon carbide powder purification device, which has the following beneficial effects:

[0017] (1) This silicon carbide powder purification device, through the setting of a spreading rack, spreading scraper and crushing unit, when using the silicon carbide powder purification device, the operator adds silicon carbide powder to the preparation hopper, and the silicon carbide powder flows into the crushing box. At the same time, the crushing motor is started, and the crushing motor drives the crushing roller to rotate. The crushing blade can crush the agglomerated silicon carbide powder. Then the silicon carbide powder falls onto the conveyor belt, and the conveyor belt can transport the silicon carbide powder. When it is transported to the position of the spreading rack, the spreading scraper spreads the silicon carbide powder, so that the silicon carbide powder is spread on the conveyor belt with a certain thickness. At the same time, the magnetic belt on the conveyor belt uses its own magnetism to attract magnetic impurities. Then the silicon carbide powder is discharged from the conveyor belt, so that the purification device can de-agglomerate and flatten the silicon carbide powder, thereby improving the purification effect.

[0018] (2) The silicon carbide powder purification device, through the set telescopic spring and sliding block, when the magnetic impurities attracted are located at the position of the scraping unit, the scraping plate scrapes the magnetic impurities on the conveyor belt, causing the magnetic impurities to fall into the material box. When the scraping plate is worn, the telescopic spring pushes the sliding block to move upward, and the sliding block drives the scraping plate to press against the conveyor belt, thus improving the scraping effect.

[0028] Furthermore, a support frame 102 is fixedly connected to the bottom of the conveyor 101, a motor frame 103 is fixedly connected to one side of the support frame 102, and a drive motor 104 is installed on the top of the motor frame 103, so that the purification device is placed more stably and is less prone to shaking.

[0029] Furthermore, a drive wheel 105 is fixedly connected to the drive end of the drive motor 104, and a transmission toothed belt 106 is movably connected to the outer side of the drive wheel 105. By starting the drive motor 104, the drive motor 104 drives the drive wheel 105 to rotate, and the drive wheel 105 can drive the transmission toothed belt 106 to rotate.

[0030] Furthermore, a drive wheel 108 is fixedly connected to one end of the conveying roller 107. The drive wheel 108 is movably connected to the drive toothed belt 106. The drive wheel 108 is driven to rotate by the drive toothed belt 106, and the drive wheel 108 drives the conveying roller 107 to rotate. At this time, the conveying roller 107 can drive the conveyor belt 109 to rotate, thereby conveying silicon carbide powder.

[0031] Furthermore, a material preparation hopper 202 is fixedly connected to the top of the crushing box 201. The material preparation hopper 202 is made of metal, making it more robust and durable and less prone to damage.

[0032] Furthermore, a scraper 305 is fixedly connected to the inner side of the sliding block 304. The outer surface of the scraper 305 is smooth.
