Description

Technical Field

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

[0002] As a key piece of equipment for ultrafine grinding of materials, the sand mill relies on the intense collision, compression, and friction between the high-speed moving grinding media and the material being ground within the cylinder. During this process, a large amount of mechanical energy is converted into heat energy, causing the internal temperature of the cylinder to rise rapidly. This is especially pronounced when processing high-viscosity, high-hardness materials or during prolonged continuous operation, where heat accumulation is even more significant, and the cylinder temperature often exceeds the ideal operating range. However, existing sand mill cooling systems generally have design limitations: most employ a single jacketed cooling structure, with refrigerant introduced only through a single-layer cooling channel on the outside of the cylinder, or the cooling components are sparsely distributed with limited coverage, resulting in insufficient heat exchange area between the refrigerant and the cylinder. Simultaneously, due to uneven heat generation in different areas of the cylinder, existing devices struggle to achieve targeted gradient cooling, easily leading to localized overheating. This inefficient and uneven cooling directly results in ineffective control of the cylinder temperature: excessively high temperatures not only accelerate the aging and wear of critical components such as internal seals and bearings, reducing equipment operational stability, but also increase the probability of downtime. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] 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.

[0020] like Figure 1 As shown, the first embodiment of this utility model provides a sand mill cooling device based on the prior art, including: a first cooling component 50, which has a limiting space, including a sand mill cylinder 10 disposed within the limiting space; multiple first cooling components 50 are spaced apart along the axial direction of the sand mill cylinder 10; each first cooling component 50 is respectively engaged with the outer side of the sand mill cylinder 10; each first cooling component 50 has a first cooling channel; a first cooling ring 60, which is sleeved on the outer side of the first cooling component 50 and has a fifth cooling channel; a second cooling ring 30, which is sleeved on the outer side of the first cooling ring 60 and spaced apart from the first cooling ring 60; the second cooling ring 30 has a second cooling channel; and a first connecting plate 40. The connecting plate 40 includes multiple first connecting plates 40, which are spaced apart circumferentially along the outer side of the first cooling ring 60. The second cooling ring 30 is connected to the first cooling ring 60 through the first connecting plates 40. The first connecting plate 40 has a third cooling channel. The second cooling component 20 is sleeved on the outer side of the second cooling ring 30. The second cooling component 20 is spaced apart from the first cooling ring 60 and the first cooling component 50. The second cooling component 20 has a fourth cooling channel. The second cooling component 20 is provided with an inlet 201 and an outlet 205. The inlet 201 and the outlet 205 are respectively connected to the fourth cooling channel. The fourth cooling channel is connected to the fifth cooling channel, the third cooling channel, the second cooling channel and the first cooling channel. The fourth cooling channel, the fifth cooling channel, the third cooling channel, the second cooling channel and the first cooling channel are used to flow the cooling medium.

[0021] In this embodiment, multiple first cooling components 50 are spaced apart along the axial direction of the sand mill cylinder 10 and cooperate with the outer side of the cylinder to further increase the cooling contact area and improve the local cooling effect. The fifth cooling channel of the first cooling ring 60, the second cooling channel of the second cooling ring 30, the third cooling channel of the first connecting plate 40 and the fourth cooling channel of the second cooling component 20 are connected to form a complete and efficient cooling medium circulation path with the liquid inlet 201 and the liquid outlet 205, which enhances the overall cooling efficiency. At the same time, the ventilation openings on the left and right sides of the device can promote air convection and accelerate the heat dissipation. The spaced arrangement of each cooling component forms an air gap, which not only avoids direct heat transfer between components affecting the cooling effect, but also further ensures structural stability and reduces cooling dead zones, making the cooling of the sand mill cylinder 10 more uniform and effectively improving the heat dissipation performance and working stability of the sand mill during operation.

[0022] Furthermore, such as Figure 2-5 As shown, the first cooling assembly 50 includes: a cooling ring unit 502, which has a limiting space and is spaced apart from the mill cylinder 10. The cooling ring unit 502 has a first cooling branch inside; multiple heat-conducting blocks 501, which are spaced apart along the inner circumference of the cooling ring unit 502. The cooling ring unit 502 is connected to the mill cylinder 10 through the multiple heat-conducting blocks 501; and multiple cooling pipes 503, which are spaced apart along the outer circumference of the cooling ring unit 502. Each cooling pipe 503 has a second cooling branch, which, together with the first cooling branch, forms a first cooling channel. Each cooling pipe 503 corresponds to one of the heat-conducting blocks 501, and each cooling pipe 503 is connected to the first cooling ring 60.

[0023] In this embodiment, multiple heat-conducting blocks 501 are spaced apart along the inner circumference of the cooling ring unit 502 and connected to the sand mill cylinder 10. This ensures structural connection stability and enhances the heat transfer efficiency between the two. The first cooling branch of the cooling ring unit 502 and the second cooling branches of multiple cooling pipes 503 form a first cooling channel. With the cooling pipes 503 and heat-conducting blocks 501 arranged in a one-to-one correspondence, the cooling medium can form targeted cooling at corresponding positions, improving cooling uniformity. The cooling pipes 503 are spaced apart along the outer circumference of the cooling ring unit 502 and connected to the first cooling ring 60, which expands the cooling contact range and facilitates connection with the overall cooling circulation system, further improving cooling efficiency and system integrity.

[0024] Furthermore, multiple first connecting plates 40 and multiple cooling pipes 503 are arranged alternately.

[0025] In this embodiment, the multiple first connecting plates 40 and multiple cooling pipes 503 are arranged in an alternating manner, which can avoid mutual interference between them in space and make the overall structural layout more compact and reasonable. At the same time, it can make the third cooling channel of the first connecting plate 40 and the second cooling branch of the cooling pipe 503 more evenly distributed in the circumference, reduce cooling dead corners, and improve the heat exchange efficiency of the cooling medium during circulation. Moreover, the alternating arrangement can disperse the structural stress, enhance the stability of the connection between the first cooling ring 60 and the first cooling component 50, and further ensure the overall reliability of the cooling system operation.

[0026] In this embodiment, the first connecting plate 40 has a plurality of first heat dissipation holes 401, and the plurality of first heat dissipation holes 401 are spaced apart along the length direction of the first connecting plate 40.

[0027] In this embodiment, the multiple first heat dissipation holes 401 on the first connecting plate 40 are spaced apart along its length, which can increase the heat dissipation area of ​​the first connecting plate 40, promote air circulation to accelerate heat dissipation, and enhance the heat dissipation effect; at the same time, it can reduce the overall weight of the first connecting plate 40, making the structure lighter without affecting the connection strength; the spaced first heat dissipation holes 401 can also optimize the stress distribution of the first connecting plate 40, and improve the overall structural stability in conjunction with its connection function, further assisting the cooling system to dissipate heat efficiently and ensuring a more balanced and reliable cooling effect.

[0028] In an exemplary embodiment, the second cooling assembly 20 includes: an outer cooling ring 202 having a third cooling branch, and an inlet 201 and an outlet 205 provided on the outer side of the outer cooling ring 202; a second connecting plate 203 including multiple second connecting plates 203, the multiple second connecting plates 203 being arranged circumferentially along the inner side of the outer cooling ring 202, the outer cooling ring 202 being connected to the second cooling ring 30 through the second connecting plate 203, the second connecting plate 203 having a fourth cooling branch, the fourth cooling branch and the third cooling branch forming a fourth cooling channel.

[0029] In this embodiment, the third cooling branch of the outer cooling ring 202 and the fourth cooling branches of multiple second connecting plates 203 form a fourth cooling channel. Combined with the liquid inlet 201 and liquid outlet 205 on the outer side of the outer cooling ring 202, efficient circulation of the refrigerant can be achieved, improving the overall circulation efficiency of the cooling system. Multiple second connecting plates 203 are spaced apart along the inner circumference of the outer cooling ring 202 and connect the outer cooling ring 202 to the first cooling ring 30. This not only enhances the stability of the structural connection but also expands the contact range between the refrigerant and the components through the evenly distributed fourth cooling branches, reducing cooling dead zones and making cooling more uniform. This structural design ensures the integrity of the cooling channel and improves heat exchange efficiency through reasonable layout, further enhancing the cooling effect on the sand mill.

[0030] In this embodiment, the second connecting plate 203 has a plurality of second heat dissipation holes 204, which are spaced apart along the length of the second connecting plate 203. The spaced arrangement of the second heat dissipation holes 204 along its length significantly increases the heat dissipation area of ​​the second connecting plate 203, promotes airflow within the second heat dissipation holes 204, accelerates the dissipation of heat from the second connecting plate 203 itself, and helps improve the overall heat dissipation effect. Simultaneously, it reduces the weight of the second connecting plate 203, making the structure lighter while ensuring the strength of its connection between the outer cold ring 202 and the second cooling ring 30. The spaced arrangement of the second heat dissipation holes 204 also optimizes the stress distribution of the second connecting plate 203, further reducing cooling dead zones in conjunction with the cooling function of its fourth cooling branch, making the heat exchange of the cooling medium more efficient, and ensuring a more stable and reliable operation of the cooling system.

It can be applied to various fields suitable for this utility model. Other modifications can be readily implemented by those skilled in the art. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and examples shown and described herein.
