Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding technology, and in particular to a grinding device. Background Technology
[0002] Vertical sand mills play a vital role as commonly used grinding equipment in chemical production and related experiments. However, during routine cleaning after daily use, the liquid inside the mill is difficult to drain effectively due to its structural characteristics.
[0003] The existing ordinary outlet is mainly used to discharge zirconium beads inside the vertical sand mill. While discharging the liquid, it cannot effectively block the zirconium beads, causing the liquid and zirconium beads to flow out at the same time. This seriously affects the normal maintenance of the vertical sand mill and subsequent experimental operations. Especially in experimental scenarios, the residual liquid inside the cylinder cannot be discharged, which makes it difficult to guarantee the solid content and yield of the product in the experiment, thereby interfering with the accuracy and reliability of the experimental results.
[0004] To address the aforementioned issues, existing vertical grinding mills include a cylinder and a filter structure. The cylinder has a drain hole, and the filter mechanism is located inside the cylinder, covering the inlet of the drain hole. This filter mechanism prevents the discharge of zirconium beads, ensuring normal maintenance and subsequent experimental operations of the vertical grinding mill. However, the filter mechanism protrudes from the upper surface of the cylinder's bottom plate. During normal grinding, the zirconium beads and materials cause direct wear to the filter mechanism, thus compromising the long-term reliable operation of the vertical grinding mill.
[0005] Therefore, there is an urgent need to design a new grinding device to improve the problem that grinding devices cannot operate reliably for a long time. Utility Model Content

[0011] A filter mechanism is disposed in the drain hole, and the upper end surface of the filter mechanism is flush with the upper end surface of the base plate.
[0012] As an optional solution, the filtration mechanism has multiple filtration channels, which can block the zirconium beads while allowing the ground material to pass through; or
[0013] The filtration mechanism is a molecular sieve structure, and the molecular sieve structure is provided with multiple pore channels.
[0014] As an optional embodiment, the cross-section of the filter channel is circular, and the radius of the cross-section of the filter channel is smaller than the radius of the zirconium bead; and / or
[0015] The filtration mechanism is made of titanium alloy or zirconium oxide.
[0016] As an optional solution, the filter mechanism is inserted into the drain hole, and the outer peripheral surface of the filter mechanism is interference-fitted with the inner peripheral surface of the drain hole.

[0018] The cylindrical body includes the bottom plate; and
[0019] A limiting member is provided on the inner wall of the drain hole, and a limiting part is provided on the filter mechanism. The limiting member cooperates with the limiting part so that the upper end surface of the filter mechanism is flush with the upper end surface of the base plate.
[0020] As an alternative, along the through direction of the drain hole, the size of the filter mechanism is a first size L1, and the size of the drain hole is a second size L2, wherein L1 / L2 is 1 / 2 to 1.
[0021] As an optional solution, the grinding device further includes a drain pipe, one end of which is connected to the end of the drain hole opposite to the grinding chamber.
[0022] As an optional solution, the grinding apparatus further includes:
[0023] A feed pipe is provided on the base plate and connected to the grinding chamber.
[0024] As an optional solution, the grinding apparatus further includes:
[0025] A zirconium bead discharge pipe is disposed on the base plate and connected to the grinding chamber.
[0026] As an optional solution, the grinding apparatus further includes:
[0027] An air intake pipe, one end of which is connected to the cylinder and communicates with the grinding chamber; and
[0028] A gas generating mechanism, wherein the other end of the air intake pipe is connected to the gas generating mechanism.
[0029] The beneficial effects of this utility model are:
[0030] This utility model provides a grinding device including a cylinder, a stirring mechanism, and a filtering mechanism. The cylinder has a grinding chamber inside and a bottom plate with a through drain hole. The stirring mechanism is located inside the cylinder and is used to stir the material and zirconium beads inside the cylinder. The filtering mechanism is located in the drain hole and its upper end face is flush with the upper end face of the bottom plate.
[0031] On the one hand, the filtration mechanism is hidden in the drain hole, so the zirconium beads and materials will not cause direct wear to the filtration mechanism during normal grinding, ensuring the long-term reliable operation of the grinding device. On the other hand, since the upper surface of the filtration mechanism is flush with the upper surface of the bottom plate, the zirconium beads and materials will not accumulate in the drain hole, ensuring smooth discharge of materials and liquids inside the cylinder.

[0051] Vertical sand mills play a crucial role as commonly used grinding equipment in chemical production and related experiments. After routine use, during normal cleaning, the liquid inside the mill's cylinder is difficult to drain effectively due to its structural characteristics. Existing standard outlets, primarily used to discharge zirconium beads, fail to effectively block the flow of liquid while simultaneously draining the beads. This results in both liquid and beads flowing out at the same time, severely impacting normal maintenance and subsequent experimental operations. Particularly in experimental settings, the inability to drain residual liquid inside the cylinder makes it difficult to guarantee the solid content and yield of the product, thus interfering with the accuracy and reliability of experimental results.
[0052] To address the aforementioned issues, existing vertical grinding mills include a cylinder and a filter structure. The cylinder has a drain hole, and the filter mechanism is located inside the cylinder, covering the inlet of the drain hole. This filter mechanism prevents the discharge of zirconium beads, ensuring normal maintenance and subsequent experimental operations of the vertical grinding mill. However, the filter mechanism protrudes from the upper surface of the cylinder's bottom plate. During normal grinding, the zirconium beads and materials cause direct wear to the filter mechanism, thus compromising the long-term reliable operation of the vertical grinding mill.
[0053] like Figure 1 As shown, the grinding apparatus 100 provided in this embodiment includes a cylindrical body 10 and a filtering mechanism 30. A grinding chamber 111 is provided inside the cylindrical body 10. The cylindrical body 10 includes a bottom plate 112, on which a through-hole 1121 is formed. The filtering mechanism 30 is disposed in the through-hole 1121, with its upper end face flush with the upper end face of the bottom plate 112. On one hand, because the filtering mechanism 30 is hidden in the through-hole 1121, the zirconium beads and materials will not cause direct wear to the filtering mechanism 30 during normal grinding, ensuring the long-term reliable operation of the grinding apparatus 100. On the other hand, because the upper end face of the filtering mechanism 30 is flush with the upper end face of the bottom plate 112, the zirconium beads and materials will not accumulate in the through-hole 1121, ensuring smoother discharge of materials and liquids from the cylindrical body 10.
[0054] In an alternative embodiment, such as Figure 1 As shown, the grinding device 100 also includes a stirring mechanism 20, which is disposed in the grinding chamber 111. The stirring mechanism 20 is used to stir the material and zirconium beads in the grinding chamber 111. By setting the stirring mechanism 20, the zirconium beads can achieve a thorough and good grinding effect on the material.
[0055] Specifically, such as Figure 1As shown, the stirring mechanism 20 includes a stirring shaft 21 and spiral blades 22. The spiral blades 22 are mounted on the stirring shaft 21, and their arrangement enables good and thorough stirring of the materials and zirconium beads. It should be noted that the stirring mechanism 20 also includes a rotary motor. The output shaft of the rotary motor is coaxially and fixedly connected to the stirring shaft 21. The rotary motor drives the stirring shaft 21 to rotate, thereby achieving good rotation of the stirring shaft 21 and the spiral blades 22, and thus ensuring thorough stirring of the zirconium beads and materials by the stirring mechanism 20.
[0056] In an alternative embodiment, such as Figure 2 As shown, the filter mechanism 30 has multiple filter channels 31. The filter channels 31 can block the zirconium beads and allow the ground material to pass through. With this filter mechanism 30, a good blocking effect on the zirconium beads can be achieved, and the ground material can be passed through smoothly.
[0057] Specifically, the cross-section of the filter channel 31 is circular, and the radius of the cross-section of the filter channel 31 is smaller than the radius of the zirconium bead. By setting the filter channel 31 with this structure, the zirconium bead can be effectively intercepted.
[0058] In an alternative embodiment, such as Figure 3 As shown, the filter mechanism 30 can be a molecular sieve structure with multiple pore channels 32. Through the setting of the molecular sieve structure, it can also effectively intercept zirconium beads.
[0059] In an optional embodiment, the filter mechanism 30 may be made of titanium alloy or zirconium oxide, thereby ensuring good strength, hardness and wear resistance of the filter mechanism 30, thereby improving the service life of the filter mechanism 30 and ensuring the long-term reliable operation of the grinding device 100.
[0060] In an optional embodiment, along the through direction of the drain hole 1121, the size of the filter mechanism 30 is a first size L1, and the size of the drain hole 1121 is a second size L2, wherein L1 / L2 is 1 / 2 to 1. By setting a relatively large size filter mechanism 30 in the drain hole 1121 within a limited space, a better and more sufficient filtration effect for zirconium beads can be achieved in a limited space. For example, L1 / L2 can be 1 / 2, 2 / 3, 3 / 4, 4 / 5, 1, etc., and all point values or range values within the above ranges are within the protection scope of this optional embodiment.
[0061] In an alternative embodiment, such as Figure 1 , Figure 4 and Figure 5As shown, the filter mechanism 30 is inserted into the drain hole 1121, and the outer circumferential surface of the filter mechanism 30 is press-fitted with the inner circumferential surface of the drain hole 1121. This ensures a good and stable connection between the filter mechanism 30 and the base plate 112, preventing the filter mechanism 30 from loosening or falling off the base plate 112 under the impact of fluid, thus guaranteeing a consistently good filtration effect. Furthermore, the press-fit between the outer circumferential surface of the filter mechanism 30 and the inner circumferential surface of the drain hole 1121 eliminates the need for additional fixing structures between the filter mechanism 30 and the base plate 112. This simplifies the connection between the filter mechanism 30 and the drain hole 1121, allowing for a stable connection within a limited space. This facilitates quick and easy assembly of the filter mechanism 30 and the base plate 112 by operators, and also makes it easy for operators to quickly disassemble and replace the filter mechanism 30.
[0062] In an alternative embodiment, such as Figure 4 and Figure 5 As shown, the cylinder 10 includes a cylinder body 11 and a limiting member 12. The cylinder body 11 includes a bottom plate 112. The limiting member 12 is disposed on the inner wall of the drain hole 1121. The filter mechanism 30 is provided with a limiting part 33. The limiting member 12 and the limiting part 33 cooperate to make the upper end surface of the filter mechanism 30 flush with the upper end surface of the bottom plate 112. Through the cooperation of the limiting member 12 and the limiting part 33, a better positioning effect between the filter mechanism 30 and the bottom plate 112 can be achieved.
[0063] For example, such as Figure 4 As shown, the limiting member 12 can be a limiting protrusion provided on the inner wall of the drain hole 1121, and the limiting part 33 can be a limiting groove provided on the side wall of the filter mechanism 30. The limiting protrusion and the limiting groove cooperate to limit the relative position of the filter mechanism 30 relative to the base plate 112.
[0064] In an optional embodiment, the limiting member 12 can be a limiting groove provided on the inner wall of the drain hole 1121, and the limiting part 33 can be a limiting protrusion provided on the side wall of the filter mechanism 30. The limiting protrusion and the limiting groove cooperate with each other, which can also limit the relative position of the filter mechanism 30 relative to the base plate 112.
[0065] In an alternative embodiment, such as Figure 4 As shown, the limiting protrusion is spherical or partially spherical. This type of limiting protrusion allows for quick assembly of the limiting protrusion and the limiting groove.
[0066] In an alternative embodiment, such as Figure 4As shown, the limiting protrusion can be made of an elastic material. The limiting protrusion deforms under external pressure, thereby achieving rapid assembly and separation of the limiting protrusion and the limiting groove. For example, the limiting protrusion can be made of materials with good elastic deformation properties, such as rubber or silicone. Of course, other materials with elastic deformation properties are also within the scope of this optional embodiment.
[0067] In an alternative embodiment, such as Figure 5 As shown, the limiting member 12 can be disposed on the inner wall of the drain hole 1121 and located at a lower position of the drain hole 1121, and the limiting part 33 can be disposed on the bottom surface of the filter mechanism 30. The limiting member 12 cooperates with the bottom surface of the filter mechanism 30 to limit the filter mechanism 30, so that the upper end surface of the filter mechanism 30 is flush with the upper end surface of the base plate 112.
[0068] In an alternative embodiment, such as Figure 1 As shown, the grinding device 100 also includes a drain pipe 40, one end of which is connected to the end of the drain hole 1121 away from the grinding chamber 111, so that the ground material can be discharged from the inside of the cylinder 10 in a better manner.
[0069] In an optional embodiment, the grinding apparatus 100 further includes a feed pipe 50, which is disposed on the bottom plate 112 and connected to the grinding chamber 111. The feed pipe 50 enables the material to enter the interior of the cylinder 10 more effectively. In addition, by feeding the material from bottom to top, a better mixing effect can be achieved.
[0070] In an alternative embodiment, such as Figure 1 As shown, the grinding device 100 also includes a zirconium bead discharge pipe 60, which is disposed on the base plate 112 and connected to the grinding chamber 111. The zirconium bead discharge pipe 60 can achieve a good discharge effect on the zirconium beads, facilitating subsequent cleaning of the zirconium beads. It should be noted that the radius of the cross-section of the zirconium bead discharge pipe 60 is larger than the radius of the zirconium beads, while the radius of the cross-section of the feed pipe 50 is smaller than the radius of the zirconium beads.
[0071] In an alternative embodiment, such as Figure 1 As shown, the grinding apparatus 100 also includes an air inlet pipe 70 and a gas generating mechanism 80. One end of the air inlet pipe 70 is connected to the cylinder 10 and communicates with the grinding chamber 111, while the other end of the air inlet pipe 70 is connected to the gas generating mechanism 80. The gas generated by the gas generating mechanism 80 increases the internal pressure of the grinding chamber 111, allowing the liquid inside the grinding chamber 111 to be quickly and thoroughly discharged through the filter mechanism 30. It should be noted that the gas generating mechanism 80 is a relatively common structure in the art, and will not be described in detail in this embodiment.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
