Description

Technical Field

[0001] The utility model relates to the technical field of silicon carbide micropowder grinding, in particular to a novel silicon carbide micropowder grinding machine. Background Art

[0002] Silicon carbide micropowder is a powder with high hardness, mainly used in the abrasive industry. It not only has stable chemical properties but also good thermal conductivity. In the production process of silicon carbide micropowder, it is often necessary to crush it first and then grind the fragments into powder.

[0003] After searching, it was found that the announcement number is CN220677981U, and the name is a silicon carbide micropowder grinding equipment. The application raised the problem that the existing silicon carbide micropowder grinding equipment is not convenient for screening the ground powder, and a dry powder pneumatic diaphragm pump is used as a circulating conveying equipment for circulating crushing.

[0004] The existing technology has the following problems:

[0005] 1. The application uses two sets of roller crushing structures as grinding equipment. The roller crushing structure has high working efficiency in the crushing stage, but has low working efficiency for micro powder grinding. The screening structure below has a large screening amount and requires a large amount of circulating crushing work, which has low working efficiency.

[0006] 2. When discharging, the dry powder pneumatic diaphragm pump ejects the powdered silicon micropowder through air pressure. The airflow will carry the silicon micropowder and overflow along the feed port, which not only leads to waste of raw materials, but also is not conducive to clean production.

[0007] To this end, we proposed a new type of silicon carbide micropowder grinding machine to solve the above disadvantages. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The present invention adopts a movable side box, a grinding head, a grinding liner and a grinding column. When grinding silicon carbide, silicon carbide can be put into the machine body, and the silicon carbide enters between the grinding head and the grinding liner. As the grinding head rotates, the silicon carbide is ground. The bottom surface of the grinding head is integrally connected with a grinding column, and the grinding column extends to the inner side of the vertical section at the bottom of the grinding liner.

At the same time, during the grinding process, cooling water enters the side box along the water inlet pipe, and is discharged along the drain pipe after the liquid level rises, forming flow cooling. The grinding liner is cooled by heat conduction, avoiding high-temperature damage during grinding and extending the overall service life.

[0019] (2) The utility model adopts a material plate, which rotates under the drive of a stepper motor. The silicon carbide that enters between the material plates is evenly fed into the interior of the machine body as the material plates rotate, thereby improving the uniformity of feeding and the uniformity of grinding. At the same time, the material plate prevents the dust generated during grinding from escaping upward from the machine body, facilitating clean production. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0028] Please refer to Figure 1-4A new type of silicon carbide micropowder grinding machine includes a body 1 and a driving motor 2. The driving motor 2 is fixedly installed on the top surface of the body 1, and a grinding head 3 is installed on the output end of the driving motor 2, and the bottom surface of the grinding head 3 is integrally connected with a grinding column 11. A side box 4 is slidably connected inside the body 1, and a grinding liner 5 is fixedly installed on the inner surface of the side box 4, and the bottom surface of the grinding liner 5 is integrally connected with a vertical section 10. An electric cylinder 7 is fixedly installed on the bottom surface of the body 1, and the top surface of the moving rod of the electric cylinder 7 is fixedly connected to the bottom surface of the side box 4. A water inlet pipe 6 is connected to the bottom surface of one end of the side box 4, and a drain pipe 9 is connected to the bottom surface of the other end of the side box 4, and the top of the drain pipe 9 extends to the top of the side box 4. A feed channel 16 is connected to the top surface of the body 1, and a feeding bin 15 is connected to the top of the feed channel 16, and a material plate 19 is provided inside the feeding bin 15.

[0029] In this embodiment: the side box 4 is an annular structure, and the outer surface of the side box 4 slides against the inner wall of the body 1. When grinding silicon carbide, silicon carbide can be put into the body 1, and silicon carbide enters between the grinding head 3 and the grinding liner 5. As the grinding head 3 rotates, silicon carbide is ground. The bottom surface of the grinding head 3 is integrally connected with a grinding column 11, and the grinding column 11 extends to the inner side of the vertical section 10 at the bottom of the grinding liner 5. The distance between the grinding column 11 and the vertical section 10 of the grinding liner 5 is equal to the target particle size of the silicon carbide micropowder. Unqualified silicon carbide micropowder cannot pass through the grinding column 11 and the vertical section 10, so the grinding column 11 is not required. The trouble of screening is eliminated, and the grinding is done in one step, which improves the grinding efficiency. At the same time, during the grinding process, the side box 4 is driven by the electric cylinder 7 to rise and fall back and forth. The grinding liner 5 is squeezed by the change of the distance between the grinding head 3 and the grinding liner 5, which plays the role of squeezing and crushing, and further improves the grinding efficiency and speed. At the same time, during the grinding process, cooling water enters the side box 4 along the water inlet pipe 6, and is discharged along the drain pipe 9 after the liquid level rises, forming flow cooling, and cooling the grinding liner 5 through heat conduction, avoiding high-temperature damage during grinding and extending the overall service life.

[0030] Specifically, the top of the feeding bin 15 is connected to the hopper 14, and the central axis of the feeding bin 15 is rotatably connected to a rotating shaft 18, and the outer wall of the rotating shaft 18 is fixedly connected to a material plate 19, and the other end of the material plate 19 is fixedly connected to a sealing strip 20, and the sealing strip 20 is in sliding contact with the inner wall of the feeding bin 15, and a stepper motor 17 is fixedly installed on the front surface of the feeding bin 15, and the output end of the stepper motor 17 is fixedly connected to one end of the rotating shaft 18.

[0031] In this embodiment: the rotating shaft 18 is rotatably connected to the feeding bin 15 through a sealed bearing, and the material plate 19 rotates under the drive of the stepper motor 17. The silicon carbide entering between the material plates 19 is evenly fed into the interior of the machine body 1 as the material plates 19 rotate, thereby improving the uniformity of the feed and the uniformity of the grinding. At the same time, the material plates 19 prevent the dust generated during grinding from escaping upward from the machine body 1, thereby facilitating clean production.

[0032] Specifically, the grinding head 3, the side box 4, the grinding liner 5, the grinding column 11 and the machine body 1 are coaxially arranged, and the grinding liner 5 and the grinding head 3 are all made of abrasive consolidation.

[0033] In this embodiment, the surface slope of the grinding head 3 is different from that of the grinding liner 5 , which facilitates step-by-step grinding of silicon carbide powder and facilitates silicon carbide of different particle sizes to enter between the grinding head 3 and the grinding liner 5 .

[0034] Specifically, the drain pipe 9 and the water inlet pipe 6 both pass through the bottom surface of the body 1 and are slidably connected to the bottom surface of the body 1, and the other ends of the drain pipe 9 and the water inlet pipe 6 are connected with a hose 8, wherein the water inlet pipe 6 is connected to the water outlet end of the industrial chiller through the hose 8, and the drain pipe 9 is connected to the input end of the industrial chiller through the hose 8.

[0035] In this embodiment, the industrial chiller is a common circulating cooling device, which is not shown in detail in the figure. The hose 8 does not affect the movement of the water inlet pipe 6 and the drain pipe 9.

[0036] Specifically, a guide rod 13 is vertically fixedly installed on the bottom surface of the other end of the side box 4, and the guide rod 13 passes through the bottom surface of the body 1 and is slidably connected to the bottom surface of the body 1.

[0037] In this embodiment, the guide rod 13 is used as a guide for the lifting of the side box 4, and a plurality of guide rods 13 are arranged.

[0038] Specifically, a funnel 12 is fixedly connected to the inner bottom surface of the body 1 , and the inner diameter of the top opening of the funnel 12 is larger than the inner diameter of the vertical section 10 .

[0039] In this embodiment, silicon carbide powder with a qualified particle size falls and is discharged from the funnel 12 .

[0040] Specifically, a bracket is fixedly installed on the bottom surface of the body 1, and a controller is fixedly installed on the rear surface of the body 1.

[0041] In this embodiment, the controller output terminal is connected to the drive motor 2, the stepper motor 17, the electric cylinder 7 and the industrial chiller input terminal, which is a common control switch form and will not be described in detail here.

[0042] Working principle: When grinding silicon carbide, silicon carbide can be put into the machine body 1, and silicon carbide enters between the grinding head 3 and the grinding liner 5. As the grinding head 3 rotates, the silicon carbide is ground. The bottom surface of the grinding head 3 is integrally connected with a grinding column 11, and the grinding column 11 extends to the inner side of the vertical section 10 at the bottom of the grinding liner 5. The distance between the grinding column 11 and the vertical section 10 of the grinding liner 5 is equal to the target particle size of the silicon carbide micropowder. Unqualified silicon carbide micropowder cannot pass through the grinding column 11 and the vertical section 10, thereby eliminating the trouble of screening, grinding and forming in one time, and improving the grinding efficiency. At the same time, during the grinding process, the side box 4 is driven by the electric cylinder 7 to lift and lower back and forth, and the grinding is carried out by changing the distance between the grinding head 3 and the grinding liner 5. The grinding liner 5 squeezes the silicon carbide between the grinding head 3 and the grinding liner 5, which plays a role of squeezing and crushing, further improving the grinding efficiency and speed. At the same time, during the grinding process, cooling water enters the side box 4 along the water inlet pipe 6, and is discharged along the drain pipe 9 after the liquid level rises, forming flow cooling. The grinding liner 5 is cooled by heat conduction, avoiding high-temperature damage during grinding and extending the overall service life. At the same time, the material plate 19 rotates under the drive of the stepper motor 17, and the silicon carbide entering between the material plates 19 is evenly fed into the inside of the machine body 1 as the material plates 19 rotate, thereby improving the uniformity of the feed and the uniformity of grinding. At the same time, the material plate 19 prevents the dust generated during grinding from escaping upward from the machine body 1, facilitating clean production.

[0043] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention.
