Description

Technical Field

[0001] This utility model belongs to the field of silicon carbide micro powder processing technology, and particularly relates to a silicon carbide micro powder iron removal device. Background Technology

[0002] Silicon carbide micro powder is a type of silicon carbide powder that has been finely processed to the micron level using specialized equipment. It is characterized by high hardness, stable chemical properties, and good thermal conductivity, and is commonly used in industries such as semiconductors, solar photovoltaics, ceramics, and refractory materials. During the production of silicon carbide micro powder, it is necessary to separate the metallic iron that is doped into it.

[0003] A search revealed a patent with application number 202320824505.4, which discloses a silicon carbide micro powder iron removal device. This patent describes a device that uses a removal component set in a conical magnet. When it is necessary to remove iron impurities from the iron removal cap, the lifting rod in the removal component can lift the iron removal cap and make it leave the conical magnet. However, in actual use, the separated iron filings still exist in the box, which requires frequent manual cleaning of the separated iron filings. The operation is cumbersome and the work efficiency is low. Utility Model Content

[0014] See appendix Figure 1 As shown, a silicon carbide micro powder iron removal device includes a housing 1 and a material guiding mechanism 8. A discharge pipe 9 is provided at the discharge port on the bottom right side of the housing 1. A partition is fixed inside the housing 1, and a feeding channel 2 is located on the left side of the partition. An impurity discharge pipe 3 communicating with the feeding channel 2 is fixed on the bottom left side of the housing 1. At least three fixing rods 4 are equidistantly fixed on both sides of the feeding channel 2, and several electromagnets 5 are equidistantly fixed on each fixing rod 4. A material guiding port 6 is provided on the partition, and a downwardly inclined fixing plate 7 is fixed at the upper end of the material guiding port 6. The material guiding mechanism 8 includes a first fixing seat 81, a movable plate 82, a second fixing seat 83, and an electric push rod 84. The first fixing seat 81 is fixed at the bottom side of the fixing plate 7, and the bottom end of the material guiding port 6 is... A movable plate 82 is connected, and the upper end of the movable plate 82 is in contact with the left side wall of the inner cavity of the feeding channel 2. A second fixed seat 83 is fixed on the upper side of the movable plate 82. The first fixed seat 81 and the second fixed seat 83 are movably connected by an electric push rod 84. By setting the feeding channel 2 in the inner cavity on the left side of the box 1 and setting the impurity discharge pipe 3 at the bottom of the feeding channel 2, the separated iron filings can be cleaned, avoiding the trouble of manual subsequent cleaning, greatly reducing the labor intensity of manual labor, improving work efficiency, and the overall structure is simple and the production cost is low. By setting the guiding mechanism 8, it is convenient to guide the silicon carbide micro powder after iron removal to the right side of the inner cavity of the box 1, and it is also convenient to discharge the separated iron filings. The operation is relatively simple.

[0015] The fixing rod 4 is inclined downwards, and the bottom ends of the fixing rod 4 at both ends do not contact each other, so as to avoid the fixing rod 4 affecting the material feeding.

[0017] Working principle: Silicon carbide micro powder containing iron filings is added into the feed channel 2. The electromagnet 5 on the fixed rod 4 adsorbs the iron filings. The separated silicon carbide micro powder passes through the movable plate 82 and the guide port 6 to the guide block 10, and is finally discharged through the discharge pipe 9. When it is necessary to clean the iron filings on the electromagnet 5, the electric push rod 84 retracts, thereby driving the movable plate 82 to rotate through the second fixed seat 83 until the movable plate 82 rotates to the guide port 6. Then, the electromagnet 5 is stopped by the external control switch, and the iron filings on the electromagnet 5 are discharged along the feed channel 2 through the impurity discharge pipe 3. By setting a feeding channel 2 in the inner cavity on the left side of the box 1 and setting an impurity discharge pipe 3 at the bottom of the feeding channel 2, the separated iron filings can be cleaned, avoiding the trouble of manual subsequent cleaning, greatly reducing the labor intensity of manual labor, improving work efficiency, and the overall structure is simple and the production cost is low. The fixing rod 4 is set in a downward inclination and the bottom ends of the fixing rod 4 at both ends do not contact each other, so as to avoid the fixing rod 4 affecting the material discharge. The bottom surface of the inner cavity of the box 1 is provided with a guide block 10, and the upper side of the guide block 10 is a guide slope that slopes downward from left to right, which improves the material discharge effect after the separation of silicon carbide micro powder.
