Description

Technical Field

[0001] This utility model relates to the field of sand mill technology, specifically a cooling device for a sand mill. Background Technology

[0002] In the processing of silicon carbide micro powder, in order to meet the stringent standards for particle size distribution in high-end ceramics, semiconductor manufacturing and other fields, the silicon carbide micro powder raw material needs to be further ground to a specific fineness. This step has extremely high requirements for equipment performance. Against this background, the sand mill, with its unique lamination grinding mechanism and efficient particle size control capability, has become the core equipment for achieving high-precision grinding of silicon carbide micro powder.

[0003] As per existing technology, patent CN117160620B discloses a sand mill for grinding water-based acrylic topcoat, comprising: a support part; a storage part mounted on the support part; a pull-out part mounted inside the storage part; a baffle part mounted at the bottom of the pull-out part; a grinding part mounted on the storage part; a stabilizing part mounted on the support part; a hollow storage tank welded to the inner side of two circular mounting columns; and a conical baffle welded to the inside of the hollow storage tank, with an arc-shaped overflow hole on the conical baffle. In this sand mill for grinding water-based acrylic topcoat, when the pull-out disc moves downwards, the raw material in the hollow storage tank moves downwards through six rings of micro-crushing holes; when the pull-out disc moves upwards, the raw material in the hollow storage tank moves upwards through the six rings of micro-crushing holes, thus achieving a secondary crushing effect on the raw material. This solves the problem that most sand mills use single crushing and grinding with crushing blades, making multiple crushing and grinding processes impossible.

[0004] The aforementioned sand mill still has certain shortcomings: Although the aforementioned sand mill can improve the collision kinetic energy and collision efficiency of the grinding media and the ground products, significantly improving the grinding efficiency, the original natural heat dissipation design of the sand mill cannot meet the heat dissipation requirements under high load or continuous operation scenarios. At this time, the metal parts of the sand mill, such as the cylinder and supporting bearings, will experience thermal expansion due to high temperature. This thermal expansion will disrupt the precise fit between the various parts of the equipment, thus adversely affecting the stable operation of the sand mill. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cooling device for a sand mill, which cools the cylinder by injecting water into the jacket, thus preventing the cylinder from being in a high-temperature state for a long time.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for a sand mill, comprising two sets of first connecting plates mounted on a cylinder, the cylinder being mounted on a vertical frame, each set of first connecting plates being symmetrically distributed, a sleeve being provided at both the front and rear ends of the cylinder, and a second connecting plate being fixedly connected to both sides of the sleeve, the first connecting plate being provided with multiple fixing bolts, and the first connecting plate and the second connecting plate being connected and fixed by fixing bolts.

[0007] Furthermore, a secondary water inlet pipe is fixedly connected to one side of the lower end of the jacket, and a secondary water outlet pipe is fixedly connected to the side of the upper end of the jacket away from the secondary water inlet pipe. Both the secondary water inlet pipe and the secondary water outlet pipe are connected to the inner side of the jacket.

[0008] Furthermore, the secondary water inlet pipe is fixedly connected to the main water inlet pipe at the end furthest from the jacket, and the secondary water outlet pipe is fixedly connected to the main water outlet pipe at the end furthest from the jacket.

[0009] Furthermore, a sealing element is fixedly connected to the inner side of the jacket.

[0010] Furthermore, a hook block is fixedly connected to the top of the second connecting plate, and the hook block is L-shaped.

[0011] Furthermore, a set of heat dissipation fins is fixedly connected to both the front and rear ends of the outer wall of the cylinder, and each set of heat dissipation fins is located inside the jacket.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The cooling device of this type of sand mill can inject cooling water into the jacket when the cylinder generates high temperatures that are difficult to dissipate in time under high load or continuous operation. The cooling water carries away the heat on the cylinder, thereby preventing the cylinder from being damaged due to high temperature. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figure 1-3 A cooling device for a sand mill includes two sets of first connecting plates 3 installed on a cylinder 2. The cylinder 2 is installed on a vertical frame 1. Each set of first connecting plates 3 is symmetrically distributed. The front end and rear end of the cylinder 2 are provided with a sleeve 5. The two sides of the sleeve 5 are fixedly connected with second connecting plates 6. The first connecting plates 3 are provided with multiple fixing bolts 7. The first connecting plates 3 and the second connecting plates 6 are connected and fixed by fixing bolts 7.

[0017] The cooling device of the sand mill in this utility model can inject cooling water into the jacket 5 when the cylinder 2 generates high temperatures that are difficult to dissipate in time under high load or continuous operation. The cooling water carries away the heat on the cylinder 2, thereby preventing damage to the cylinder 2 due to high temperature. At the same time, the jacket 5 is connected to the cylinder 2 through the second connecting plate 6 and fixing bolts 7, which allows the jacket 5 to be disassembled. When the cylinder 2 is under low load or short-term operation, the jacket 5 can be removed from the cylinder 2, and the cylinder 2 can dissipate heat by its own heat dissipation function, without the need for additional water cooling, thus reducing costs. In addition, the structure of the upright frame 1 and the cylinder 2 in this utility model is similar to the prior art, which discloses a sand mill structure for grinding water-based acrylic topcoat in patent patent authorization announcement number CN117160620B, so it will not be described in detail here.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, a secondary water inlet pipe 10 is fixedly connected to one side of the lower end of the jacket 5, and a secondary water outlet pipe 12 is fixedly connected to the side of the upper end of the jacket 5 away from the secondary water inlet pipe 10. Both the secondary water inlet pipe 10 and the secondary water outlet pipe 12 are connected to the inner side of the jacket 5.

[0019] like Figure 1 and Figure 2 As shown, the secondary water inlet pipe 10 is fixedly connected to the main water inlet pipe 11 at the end away from the jacket 5, and the secondary water outlet pipe 12 is fixedly connected to the main water outlet pipe 13 at the end away from the jacket 5.

[0020] Specifically, both jackets 5 are supplied with cooling water by the main inlet pipe 11, and the cooling water in both jackets 5 eventually flows out from the main outlet pipe 13. In addition, the main inlet pipe 11 and the main outlet pipe 13 are connected to external cooling equipment, such as heat exchangers or cooling towers. Since these are existing mature products and technologies, they will not be described in detail here, and are not shown in detail in the figure.

[0021] like Figure 3 As shown, a seal 8 is fixedly connected to the inner side of the jacket 5.

[0022] Specifically, the seal 8 can be made of elastic materials such as rubber rings. The seal 8 can fill the gap between the jacket 5 and the cylinder 2 to prevent cooling water from flowing out of the gap.

[0023] like Figure 2 and Figure 3 As shown, a hook block 9 is fixedly connected to the top of the second connecting plate 6. The hook block 9 is L-shaped.

[0024] Specifically, when installing the sleeve 5, the sleeve 5 can be suspended on the first connecting plate 3 by the hook block 9, so that it can be fixed by the fixing bolt 7 later.

[0025] like Figure 2 As shown, a set of heat dissipation fins 4 are fixedly connected to the front and rear ends of the outer wall of the cylinder 2, and each set of heat dissipation fins 4 is located inside the jacket 5.

[0026] Specifically, when the jacket 5 is installed on the cylinder 2, the heat dissipation fins 4 will increase the surface area of ​​the outer wall of the cylinder 2 and improve the heat exchange efficiency. After the jacket 5 is removed, the heat dissipation fins 4 will play a heat dissipation role and enhance the heat dissipation effect of the cylinder 2 itself.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
