Description

Technical Field

[0001] This utility model relates to the field of corundum particle production and processing technology, and in particular to a corundum particle grinding mill. Background Technology

[0002] Corundum micro powder is a relatively common micro powder and abrasive. Using it for processing is not only fast, but also has advantages such as high purity, good self-sharpening properties, strong grinding ability, low heat generation, high efficiency, resistance to acid and alkali corrosion, and good high temperature thermal stability. The emergence of corundum micro powder has greatly facilitated our production and life.

[0003] A white fused alumina particle grinding mill disclosed in Chinese patent CN212882729U features a box body with a metering plate installed inside. The metering plate determines the required amount of material by fixing a weight at one end and adding a corresponding weight of material at the other end through a lever action, thus achieving quantitative grinding.

[0004] However, a comparison with existing technologies and solutions reveals that existing corundum particle grinding mills require grinding the corundum particles first, and then sieving the ground powder to return any incompletely ground corundum particles to be regrinded. The grinding and sieving functions are separate, resulting in low production efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a corundum particle grinding mill.

[0006] The purpose of this utility model is achieved through the following technical solution: a corundum particle grinding mill, including a grinding cylinder, a driven gear fixedly connected to one side of the grinding cylinder, a fixed frame rotatably connected to the other end of the grinding cylinder, a head rotatably connected to one side of the driven gear, and a support fixedly connected to the bottom of the head.

[0007] The grinding cylinder has a grinding table on its inner wall, a filter ring is fixedly connected to one side inside the grinding cylinder, a tapered tube is provided inside the grinding cylinder, one end of the tapered tube is fixedly connected to the end cap, an auger is rotatably connected inside the tapered tube, a rotating shaft is fixedly connected to the middle of the auger, and the rotating shaft is fixedly connected to the grinding cylinder.

[0008] Preferably, a base is fixedly connected to the bottom of the fixing frame.

[0009] Preferably, a feeding bin is fixedly connected to one side of the end cap.

[0010] Preferably, a discharge port is fixedly connected to one side of the fixing frame.

[0011] Preferably, a motor is provided on one side of the bracket.

[0012] Preferably, the output end of the motor is fixedly connected to a drive gear.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The corundum particle grinding mill, by setting up a conveying device and a filtering device, allows the corundum particles entering the grinding cylinder to be ground during the working process. Some of the fully ground corundum particles enter the discharge port through the filter ring, while some of the not fully ground corundum particles are conveyed to the feed port for further grinding by the auger. This can realize the integration of filtration and circulating grinding, thereby improving the production efficiency of corundum particles.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0020] like Figure 1-4 As shown, a corundum particle grinding mill includes a grinding cylinder 4. A driven gear 3 is fixedly connected to one side of the grinding cylinder 4, and a fixed frame 15 is rotatably connected to the other end of the grinding cylinder 4. A head 5 is rotatably connected to one side of the driven gear 3. A through hole is opened inside the head 5, which communicates with the feeding bin 6 and the grinding cylinder 4. A bracket 7 is fixedly connected to the bottom of the head 5. The inner wall of the grinding cylinder 4 is provided with a grinding table 10. The grinding table 10 is inclined, which can increase the interaction force between particles and assist feeding during collision. A filter ring 11 is fixedly connected to one side inside the grinding cylinder 4. A conical tube 12 is provided inside the grinding cylinder 4. There is a gap between the filter ring 11 and the conical tube 12. Incompletely ground corundum particles fall into the conical tube 12 through the gap. One end of the conical tube 12 is fixedly connected to the end cap 5. An auger 13 is rotatably connected inside the conical tube 12. One end of the auger 13 is fixedly connected to a rotating shaft 14. The rotating shaft 14 is fixedly connected to the grinding cylinder 4. The connection between the rotating shaft 14 and the grinding cylinder 4 is a cross-shaped structure, which forms a channel for corundum powder to pass through with the filter ring 11.

[0021] As a preferred technical solution of this utility model, the bottom of the fixing frame 15 is fixedly connected to the base 9, and the height of the base 9 is lower than that of the bracket 7, which facilitates the feeding of corundum particles.

[0022] As a preferred technical solution of this utility model, a feeding bin 6 is fixedly connected to one side of the end cap 5.

[0023] As a preferred technical solution of this utility model, a discharge port 8 is fixedly connected to one side of the fixing frame 15.

[0024] As a preferred technical solution of this utility model, a motor 1 is provided on one side of the bracket 7.

[0025] As a preferred technical solution of this utility model, the output end of the motor 1 is fixedly connected to the drive gear 2.

[0026] The work process is as follows: When the work begins, corundum particles enter the grinding cylinder 4 from the feeding hopper 6. The motor 1 is started, and the output end of the motor 1 drives the drive gear 2 to rotate. The drive gear 2 drives the driven gear 3 to rotate, and the driven gear 3 drives the grinding cylinder 4 to rotate. As the grinding cylinder 4 rotates, the corundum particles collide with the conical tube 12 and the grinding table 10, and the corundum particles also collide with each other. The gap between the conical tube 12 and the grinding cylinder 4 gradually decreases from the feeding point to the discharge port 8, which can make the corundum particles grind more thoroughly, and finally reach the discharge port 8.

[0027] After the ground corundum particles reach the discharge port 8, some of the fully ground corundum powder passes through the filter ring 11 and is collected in the discharge port 8. Some incompletely ground corundum particles fall into the auger 13 from the gap between the filter ring 11 and the conical tube 12. As the grinding cylinder 4 rotates, the rotating shaft 14 rotates, which drives the auger 13 to rotate, returning the incompletely ground corundum particles to the grinding process. This integrates filtration and circulating grinding, improving the production efficiency of corundum particles.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
