[0023] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0024] Please refer to Figures 1-7. This invention provides a technical solution: a special grinding equipment for iron oxide powder, including a support frame with fixed relative positions, a housing 1 mounted on the support frame, a feed pipe 2 mounted on the upper side of the housing 1, a processing mechanism 3 for restricting material flow from the feed pipe 2, a through hole below the feed pipe 2 in the housing 1, a grinding mechanism 4 for grinding materials detachably fixed at the through hole in the housing 1, forming a structure where the grinding mechanism 4 enters and exits the housing 1 through the through hole, a baffle 7 for concentrating materials is mounted above the grinding mechanism 4 in the housing 1, an outlet 8 is provided between the baffle 7 and the feed pipe 2 in the housing 1, the outlet 8 is connected to a cyclone separator 9 via an air pipe, and a drive mechanism is mounted below the grinding mechanism 4 in the housing 1, forming a structure where the material is moved to the outlet 8 or onto the baffle 7 by the drive mechanism. In use… Materials such as iron oxide particles enter the housing 1 through the feed pipe 2. The size of the iron oxide particles entering is less than or equal to 0.2 cm. The material passes through the processing mechanism 3 and the baffle 7, and then enters the grinding mechanism 4 for grinding. If the ground material meets the production standards, it is moved to the discharge port 8 by the drive mechanism and passes through the cyclone separator 9 to obtain a qualified product. If it does not meet the production standards, it is moved to the baffle 7 by the drive mechanism and then ground again by the grinding mechanism 4. At the same time, if the ground material flows into the feed pipe 2, the processing mechanism 3 restricts the material from flowing out of the feed pipe 2, so as to both prevent the material from flowing out of the feed port and allow for feeding at any time. In addition, the detachable fixing of the grinding mechanism 4 and the housing 1, as well as the cooperation of the through hole, facilitates the installation and disassembly of the grinding mechanism 4, and is conducive to the maintenance and replacement of the grinding mechanism 4.

[0025] In one embodiment, the housing 1 includes a first side plate 1.1 and a second side plate 1.2. An annular plate 1.3 with a circular structure is installed between the first side plate 1.1 and the second side plate 1.2. The annular plate 1.3 is welded and fixed to the first side plate 1.1 and the second side plate 1.2.

[0026] In one embodiment, a feed inlet is provided at the top of the annular plate 1.3. The annular plate 1.3 is welded and fixed to the feed pipe 2 through the feed inlet. A baffle 7 is welded and fixed between the first side plate 1.1 and the second side plate 1.2. There are two baffles 7, which are arranged in an inverted V shape. The discharge port 8 is located at the edge of the annular plate 1.3. Through holes are provided on the first side plate 1.1 and the second side plate 1.2.

[0027] In one embodiment, the bracket is a common support structure in the prior art, which is not shown in the accompanying drawings. The bracket is welded and fixed to the annular plate 1.3.

[0028] In one embodiment, the driving mechanism includes air holes 5, each air hole 5 being opened at an annular plate 1.3 on the housing 1. The axis of each air hole 5 is perpendicular to the radial direction of the annular plate 1.3 at its location, or may be arranged slightly at an angle. Each air hole 5 is connected to the air outlet in a blowing device via a pipe. The blowing device is a suitable device such as an air blower. There are approximately two or more air holes 5, located on both sides of the lowest point of the annular plate 1.3. Through the blowing device, the material at the bottom of the annular plate 1.3 moves upward along the annular plate 1.3. Due to the different particle sizes and weights of the material, the material... The height at which the annular plate 1.3 moves upward along the circular structure also varies. The qualified material is lighter, while the unqualified material is heavier. After moving a certain distance along the annular plate 1.3, the unqualified material separates from the annular plate 1.3, moves in a parabolic motion, and falls onto the baffle 7. Then it is ground again by the grinding mechanism 4. The qualified material moves in a circular motion along the annular plate 1.3. When it reaches the discharge port 8, it is moved outside the box 1 by the cyclone separator 9. This forms a structure in which the material is moved to the discharge port 8 or onto the baffle 7 by the driving mechanism.

[0029] In one embodiment, the grinding mechanism 4 includes a first roller 4.1 and a second roller 4.2. One end of the first roller 4.1 and the second roller 4.2 is rotatably connected to a first support plate 4.3 via a first coupling shaft, and the other end of the first roller 4.1 and the second roller 4.2 is rotatably connected to a second support plate 4.4 via a second coupling shaft. The portion of each second coupling shaft extending through the second support plate 4.4 is keyed to fix a driven wheel 4.5. The first support plate 4.3 and the second support plate 4.4 are bolted to the housing 1. The first roller 4.1 and the connected first coupling shaft and the second coupling shaft are an integral structure, and the second roller 4.2 and the connected first coupling shaft and the second coupling shaft are an integral structure. Each coupling shaft is rotatably connected to each support plate via bearings. The material is ground by the operation of the first roller 4.1 and the second roller 4.2.

[0030] In one embodiment, the first support plate 4.3 includes a first plate 4.3.1 and a second plate 4.3.2, which are integrally formed. The second support plate 4.4 includes a third plate 4.4.1 and a fourth plate 4.4.2, which are also integrally formed. The second plate 4.3.2 and the third plate 4.4.1 are the same size, the first plate 4.3.1 is larger than the second plate 4.3.2, and the fourth plate 4.4.2 is smaller than the third plate 4.4.1. The through holes include a first hole 6 that mates with the first support plate 4.3 and a second hole 12 that mates with the second support plate 4.4. The first hole 6 and the second hole 12 are stepped holes. The first hole 6 is fitted onto the first support plate 4.3, and the second hole 12 is fitted onto the second support plate 4.4. 2. The outer sleeve is fitted onto the second support plate 4.4. The second plate 4.3.2 and the fourth plate 4.4.2 are bolted to the housing 1. The projections of the first roller 4.1, the second roller 4.2, and the driven wheel 4.5 along the axial direction of the first roller 4.1 onto the third plate 4.4.1 are all located on the third plate 4.4.1. This facilitates the movement of the grinding mechanism 4 from the through hole to the outside of the housing 1 or its installation inside the housing 1. This forms a structure in which the grinding mechanism 4 enters and exits the housing 1 through the through hole. Since the second plate 4.3.2 and the fourth plate 4.4.2 are bolted to the housing 1, the second plate 4.3.2 and the fourth plate 4.4.2 can be bolted to the housing 1 or separated from it. This allows the grinding mechanism 4 and the housing 1 to be detachably and fixedly connected.

[0031] In one embodiment, mounting holes are provided on the first support plate 4.3 and the second support plate 4.4. Bearings connected to each roller are installed in the mounting holes. The first cover plate is bolted to the outside of the mounting holes on the first support plate 4.3, and the second cover plate is bolted to the outside of the mounting holes on the second support plate 4.4. Each second cover plate has a through hole for each connecting shaft to pass through. A sealing ring is installed at the connection between the second cover plate and the connecting shaft, and a sealing ring is installed at the connection between each mounting hole and the connecting shaft.

[0032] In one embodiment, a motor 10 is bolted to the bracket, and a drive wheel 11 is keyed to the output shaft of each motor 10. Each drive wheel 11 is geared to a driven wheel 4.5. The driven wheels 4.5 rotate in opposite directions. Each drive wheel 11 and driven wheel 4.5 is a gear. There are two motors 10, drive wheels 11, and driven wheels 4.5. The operation of each motor 10 causes each roller to rotate.

[0033] In one embodiment, the processing mechanism 3 includes a first partition 3.1 and a second partition 3.2, which are arranged in a V-shape. The upper ends of the first partition 3.1 and the second partition 3.2 are rotatably connected to the feed pipe 2 via a round shaft, and the lower ends of the first partition 3.1 and the second partition 3.2 are in contact with each other. An elastic element 3.3 made of an elastic material such as a spring is snapped and fixed between the first partition 3.1, the second partition 3.2 and the feed pipe 2. A stop block 3.4 is glued and fixed directly above the upper end of the first partition 3.1 and the second partition 3.2. A sealing strip 3.5 is installed between each stop block 3.4 and the first partition 3.1 and the second partition 3.2. Each sealing strip 3.5 is glued and fixed to the stop block 3.4 and in contact with the surface of each partition. The feed pipe 2 is connected to the first partition 3.1 and the second partition 3.2. 1. A fixing block 3.6 is bonded to the upper side of the second partition 3.2. The stop block 3.4 prevents material from falling between the upper part of each partition and the feed pipe 2, which would affect the rotation of the partition. The fixing blocks 3.6 limit the rotation position of each partition. When material falls into the first partition 3.1 and the second partition 3.2, the partitions rotate downward under the action of gravity, so that the material can enter the box 1 from between the first partition 3.1 and the second partition 3.2. Different materials cause different rotation angles of each partition, so the interval between the first partition 3.1 and the second partition 3.2 is also different. Therefore, the size of the material inlet is adjusted in real time according to the material entry situation, and the diameter of the powder material flowing out of the feed pipe 2 is limited, that is, the powder material is concentrated for the next step of powder material processing.

[0034] In one embodiment, the feed pipe 2 has an air intake hole 3.7 directly above the contact point between the first partition 3.1 and the second partition 3.2. The feed pipe 2 is fixed with a filter screen 3.8 at the air intake hole 3.7. Each air intake hole 3.7 is connected to the air inlet of the suction device. The air outlet of the suction device is connected to the air inlet of the drive mechanism. The air outlet of the suction device is connected to the pipe connected to the air inlet through an air pipe. The suction device is a suitable device such as a vacuum pump. By operating the suction device, the powder material located above each partition is extracted and the extracted material is discharged into the box 1 through the air inlet, thereby preventing the material from flowing out from the feed pipe 2.

[0035] The method of using a special grinding equipment for iron oxide powder includes the following steps: turn on the motor 10, the blowing device, the exhaust device, and the cyclone separator 9; feed the material into the feed pipe 2; and collect the material at the cyclone separator 9.

[0036] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
