[0026] The present utility model provides the following description with reference to the accompanying drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to facilitate understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0027] In the description of the present utility model, when it comes to orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0028] It should be understood that when an element (e.g., the first element) is "connected" to another element (e.g., the second element), the element can be directly connected to the other element, or there can be an intermediate element (e.g., the third element) between the element and the other element.

[0029] An embodiment of the present utility model provides a colloid mill with a cooling system, as Figure 1-8 shown, including:

[0030] A colloid mill main body 100, the colloid mill main body 100 includes a grinding device 110 and a driving device 120. An inlet pipe 130 and an outlet pipe 131 are provided on the grinding device 110. The grinding device 110 includes a moving grinding disc 132, a static grinding disc 133, and a blanking device 134. The power output end of the driving device 120 is connected to the moving grinding disc 132. The moving grinding disc 132 and the static grinding disc 133 cooperate to form a grinding chamber 135. The blanking device 134 is used to feed materials into the grinding chamber 135. Heat dissipation fins 136 are evenly distributed on the outer surface of the static grinding disc 133;

[0031] A cooling system 200, the cooling system 200 includes a cooling component 210 sleeved outside the static grinding disc 133. The cooling component 210 and the static grinding disc 133 cooperate to form a cooling cavity. An inlet water port 220 and an outlet water port 230 communicating with the cooling cavity are provided on the cooling component 210.

[0032] The grinding device 110 has a feed pipe 130 and a discharge pipe 131, allowing the entry of materials and the discharge of finished products. The moving grinding disc 132 works in cooperation with the stationary grinding disc 133 in the grinding device 110 to achieve the grinding of materials. The stationary grinding disc 133 corresponds to the moving grinding disc 132, and heat dissipation fins 136 are evenly distributed on its outer surface, which helps to dissipate heat during the grinding process. The driving device 120 provides power, and its power output end is connected to the moving grinding disc 132 to drive the moving grinding disc 132 to rotate, achieving the grinding of materials. The grinding chamber 135 is formed by the cooperation of the moving grinding disc 132 and the stationary grinding disc 133, and it is the space where materials are ground. The cooling system 200 is used to cool the grinding discs during the grinding process to prevent overheating. The cooling component 210 is sleeved outside the stationary grinding disc 133 and can be a cooling sleeve or a similar structure.

[0033] During use, materials first enter the grinding device 110 through the feed pipe 130. The feeder is responsible for evenly distributing the materials onto the surface of the stationary grinding disc 133. The moving grinding disc 132 rotates driven by the driving device 120, and the materials are ground into the required fineness between the two grinding discs. The close cooperation between the moving grinding disc 132 and the stationary grinding disc 133 forms the grinding chamber 135, and the materials are subjected to shear, impact, and frictional forces in this chamber. Since heat is generated during the grinding process, the heat dissipation fins 136 evenly distributed on the outer surface of the stationary grinding disc 133 help to dissipate this heat. The heat dissipation fins 136 increase the contact surface area and improve the heat dissipation efficiency. The cooling system 200 works through the cooling component 210. The cooling component 210 is sleeved outside the stationary grinding disc 133, and coolant (usually water) is introduced through the water inlet 220. The coolant flows inside the cooling component 210, absorbs the heat of the stationary grinding disc 133, and then is discharged through the water outlet 230, thereby achieving the cooling of the stationary grinding disc 133. The ground materials are discharged through the discharge pipe 131.

[0034] Through the cooling system 200, the heat generated during the grinding process can be effectively controlled, preventing the grinding discs from overheating, thereby improving the grinding efficiency and product quality and extending the service life of the equipment. At the same time, the uniform distribution of the heat dissipation fins 136 helps to improve the cooling efficiency.

[0035] In some embodiments, the stationary grinding disc 133 includes a cooling portion 137 and a grinding portion 138 for cooperating with the moving grinding disc 132 to perform grinding, and the heat dissipation fins 136 are provided on the cooling portion 137.

[0036] The stationary grinding disc 133 is divided into a cooling portion 137 and a grinding portion 138. The cooling portion 137 is specifically used for heat dissipation and is provided with heat dissipation fins 136. The grinding portion 138 is in direct contact with the moving grinding disc 132 to perform the grinding work of materials.

[0037] Furthermore, the cooling portion 137 is frustum-shaped, and the heat dissipation fins 136 are radially distributed on the circumferential surface of the cooling portion 137.

[0038] The cooling part 137 is designed to be frustum-shaped, which is a geometric shape with a larger bottom diameter than the top diameter, similar to an inverted conical shape. The heat sinks 136 are radially distributed on the circumferential surface of the cooling part 137, and the heat sinks 136 are closely fitted with the cooling part 137. This fitting method means that the heat sinks 136 may be arranged along the frustum surface of the cooling part 137. When the heat sinks 136 are combined with the cooling part 137, their outer contours form a cylindrical shape. This design helps to maximize the heat dissipation area while maintaining the compactness and symmetry of the device. The cylindrical outer contour helps to improve the cooling efficiency because this shape can provide a larger surface area to contact the cooling water, thereby transferring heat more effectively.

[0039] Furthermore, the static grinding disc 133 and the heat sinks 136 are integrally formed.

[0040] In some embodiments, the cooling component 210 includes a sleeve 240 for storing the coolant and a sealing cover 250, and the sealing cover 250 is provided with a water inlet 220 and a water outlet 230.

[0041] The sleeve 240 in the cooling component 210 is a container for storing the coolant (usually water or other cooling media). This sleeve 240 is designed to be sleeved outside the static grinding disc 133 to play a role in surrounding and protecting the static grinding disc 133. The sealing cover 250 is a part of the sleeve 240. It covers the opening of the sleeve 240 to ensure that the coolant does not leak and at the same time maintains the tightness inside the cooling system 200. The design of the sealing cover 250 needs to ensure that the coolant can flow in the cooling system 200 without leakage. The water inlet 220 is an interface on the sealing cover 250 for introducing the coolant into the cooling system 200. This interface can be connected to an external coolant supply system to ensure that the coolant can smoothly enter the sleeve 240. The water outlet 230 is another interface on the sealing cover 250 for discharging the used coolant in the cooling system 200. This interface is connected to an external discharge system to discharge the heated coolant and may be reused or processed. The coolant enters the sleeve 240 through the water inlet 220, then flows along the inside of the cooling component 210, contacts the surface of the static grinding disc 133, and absorbs the heat generated by the grinding process. After that, the heated coolant is discharged through the water outlet 230 to complete a heat exchange cycle.

[0042] In some embodiments, an adjusting device 139 for adjusting the distance between the dynamic grinding disc 132 and the static grinding disc 133 is provided outside the grinding part 138.

[0043] The main purpose of the adjusting device 139 is to allow the operator to adjust the gap between the moving grinding disc 132 and the stationary grinding disc 133 according to the characteristics of the grinding material and the required grinding fineness. This can ensure that the material is effectively ground while avoiding excessive wear of the grinding discs. The adjusting device 139 may adopt a mechanical or hydraulic adjustment method. Mechanical adjustment usually involves using screws, gears or other mechanical structures to change the distance between the grinding discs. Hydraulic adjustment uses hydraulic pressure to adjust the gap between the grinding discs. Some adjusting devices 139 may be equipped with scales or sensors to ensure precise control of the grinding disc spacing.

[0044] Furthermore, the colloid mill with a cooling system further includes a fixing device 140, and the adjusting device 139 is provided with positioning holes 141 for cooperating with and fixing to the fixing device 140.

[0045] The positioning holes 141 are specific structures on the adjusting device 139 for ensuring that the adjusting device 139 maintains an accurate and stable position during the adjustment process. These holes can be circular, square or other shapes, depending on the design of the fixing device 140 that cooperates with them. The fixing device 140 is a component that cooperates with the positioning holes 141 for fixing the adjusting device 139 to prevent it from moving or vibrating during operation. The fixing device 140 may include bolts, screws, buckles or other fasteners.

[0046] In some embodiments, the feeder 134 is fixedly connected to the moving grinding disc 132.

[0047] Furthermore, the feeder 134 includes a spiral feeding rod.

[0048] In some embodiments, the discharge pipe 131 is connected with a circulation pipe 142 for circulating and grinding the material and a control switch 143.

[0049] The circulation pipe 142 is a pipe connecting the discharge pipe 131 for redirecting part or all of the material from the discharge pipe 131 back to the grinding device 110 to achieve circulating grinding of the material. This design allows the material that has not reached the required fineness to pass through the grinding process again to improve the grinding efficiency and product quality. The control switch 143 is a valve or gate for controlling the flow direction of the material in the circulation pipe 142. By operating the control switch 143, the operator can decide whether the material is directly discharged or returned to the grinding device 110 for re-grinding. By using the circulation pipe 142 and the control switch 143, the circulation volume can be flexibly adjusted according to the grinding fineness requirements of the material to ensure that the final product meets the required quality standards.
