Description

Technical Field

[0001] This utility model relates to a ball mill cooling device for producing pearlescent pigments. Background Technology

[0002] Our company's main product is pearlescent pigments. One of the main pieces of equipment for pearlescent pigments is the ball mill. When grinding pearlescent powder with a ball mill, the impact and friction between the steel balls and the pearlescent particles generate a certain amount of heat, causing the temperature inside the mill cylinder to rise continuously and approach the combustion temperature. If the temperature is not controlled ideally, it can easily cause fire and explosion hazards.

[0003] Our company previously used a method of spraying tap water onto the outer surface of the grinding cylinder to cool it down. The cooling effect of this method depends on the amount of water sprayed. Over time, the scale buildup from the tap water caused the spray holes to become clogged, resulting in a decrease in cooling efficiency. Utility Model Content

[0004] This utility model provides a cooling device for a ball mill used in the production of pearlescent pigments, which solves the problem of reduced cooling effect caused by scale buildup in tap water clogging the spray nozzles. The specific solution is as follows:

[0005] A ball mill cooling device for producing pearlescent pigments includes a grinding cylinder and a water tank arranged horizontally along their axis, with the lower end of the grinding cylinder placed in the water tank;

[0006] The grinding cylinder has a cylindrical outer peripheral surface, and multiple mounting brackets extending along the axis are evenly distributed on the outer peripheral surface and along its circumferential direction. Each mounting bracket is equipped with a long strip of water-scooping strip, and a water-blocking wall is provided on each side of the mounting bracket.

[0007] The water tank includes a water-holding section located at the bottom, the length of which extends along the axis of the grinding cylinder, and the water-holding section stores cooling water. When the grinding cylinder rotates, at least one of the water-scooping bars at its bottom is submerged below the surface of the cooling water.

[0008] The water-holding part has upward connecting parts on both sides, and the upper part of each connecting part is connected to the water-blocking part.

[0009] The water-retaining wall is located in the water tank.

[0010] Furthermore, the connecting portion is wrapped around the outside of the grinding cylinder.

[0011] Furthermore, the water-blocking part extends outward.

[0012] Furthermore, the water-holding section is equipped with an inlet pipe and a return pipe.

[0013] Optionally, the mounting bracket includes a mounting plate connected to the outer peripheral surface, and a clamping plate extends outward from the outer center of the mounting plate, with a clamping groove extending in the axial direction at the top of the clamping plate.

[0014] The lower end of the scooping bar is installed in the clamping groove.

[0015] Furthermore, the bottom of the clamping plate is a concave surface that matches the outer peripheral surface.

[0016] Optionally, the scooping bar includes a vertical portion located below, the lower end of which is connected to the clamping groove;

[0017] The top of the vertical section is provided with an inclined section for water storage;

[0018] The top of the vertical section is provided with an inclined section for water storage, and the inclined direction of the inclined section is the same as the rotation direction of the grinding cylinder.

[0019] The beneficial effects are:

[0020] 1. A water-scooping strip is installed on the outer circumference of the grinding cylinder to scoop up water from the water tank and spray it onto the outer circumference of the grinding cylinder during rotation to achieve cooling. It has the advantages of large water volume and good cooling effect.

[0021] 2. There is no problem of scale clogging the spray holes, ensuring long-term stable operation;

[0022] 3. A retaining wall is also installed to prevent water from flowing down from both sides along the axis;

[0023] 4. The water tank is also equipped with a water-blocking part to reduce the phenomenon of water being spilled onto the ground during the rotation of the grinding cylinder. Attached Figure Description

[0039] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0040] Please see Figures 1 to 3 A ball mill cooling device for producing pearlescent pigments includes a grinding cylinder 1 and a water tank 2 arranged horizontally along the axis, with the lower end of the grinding cylinder 1 placed in the water tank 2;

[0041] The grinding cylinder 1 has a cylindrical outer peripheral surface, and multiple mounting brackets 4 extending along the axis are evenly distributed on the outer peripheral surface and along its circumferential direction. Each mounting bracket 4 is equipped with a long strip of water-scooping strip 5, and a water-blocking wall 3 is provided on each side of the mounting bracket 4.

[0042] The water tank 2 includes a water-holding section 2a located at the bottom. The length direction of the water-holding section 2a extends along the axis of the grinding cylinder 1. Cooling water is stored in the water-holding section 2a. When the grinding cylinder 1 rotates, at least one of the water-scooping bars 5 at its bottom is submerged below the surface of the cooling water.

[0043] The water-holding part 2a has upward connecting parts 2b on both sides. The connecting parts 2b wrap around the outside of the grinding cylinder 1. The upper part of each connecting part 2b is connected to the water-blocking part 2c. In order to increase the interception range, the water-blocking part 2c extends outward.

[0044] The water-blocking wall 3 is located in the water tank 2 and is used to block more water from being sprayed.

[0045] In this application, a water tank 2 is set at the bottom of the grinding cylinder 1, and cooling water is stored in the water tank 2. The grinding cylinder 1 is partially submerged in the water. A water strip 5 is set on the outer circumference of the grinding cylinder 1 to scoop up the water in the water tank 2 and spray it onto the outer circumference of the grinding cylinder 1 during rotation to achieve cooling. Water baffles 3 are set at both ends of the water strip 5 to block the water and prevent it from flowing down from the side. Therefore, this solution has the advantages of large water volume and good cooling effect. In addition, there is no problem of scale clogging the spray holes, which ensures long-term stable operation.

[0046] The water tank 2 is also equipped with a water-blocking part 2c to reduce the phenomenon of water being spilled onto the ground during the rotation of the grinding cylinder 1, thereby reducing the workload of workers and saving water.

[0047] Please see Figure 4 In order to circulate the cooling water in the water tank 2, the water holding part 2a is provided with an inlet pipe 2aa and a return pipe 2ab. The inlet pipe 2aa and the return pipe 2ab are used to connect the circulating water, which can cool the cooling water in the water tank 2 and also make appropriate water replenishment.

[0048] Please see Figure 5 The mounting frame 4 includes a mounting plate 4a connected to the outer peripheral surface. The clamping plate 4a is fixed to the outer peripheral surface of the grinding cylinder 1 by welding. A clamping plate 4b extends outward from the outer center of the mounting plate 4a. A clamping groove 4ba extending in the axial direction is opened on the top of the clamping plate 4b.

[0049] The lower end of the scooping bar 5 is installed in the clamping groove 4ba by screws;

[0050] As can be seen in the figure, the bottom of the clamping plate 4a is a concave surface that matches the outer peripheral surface, which can obtain a larger contact surface;

[0051] The water-scooping bar 5 includes a vertical part 5a located at the bottom, and the lower end of the vertical part 5a is connected to the clamping groove 4ba;

[0052] The top of the vertical part 5a is provided with an inclined part 5b for storing water. The inclined direction of the inclined part 5b is the same as the rotation direction of the grinding cylinder 1. When rotating, the inclined part 5b achieves the purpose of scooping up the water in the water tank 2 and taking it away.

[0053] The method of use is as follows: fill water into the water-holding section 2a and manually observe the water level. When the water level reaches the set value, turn on the circulating water for circulating cooling.

[0054] As the grinding cylinder 1 rotates, the water-scooping strips 5 on the outer circumference of the grinding cylinder 1 scoop up the water in the water-holding section 2a and sprinkle it onto the outer circumference of the grinding cylinder 1 during the rotation of the grinding cylinder 1 to achieve cooling.

[0055] During the rotation of the grinding cylinder 1, water at the top will be thrown out due to centrifugal force. At this time, the water is blocked by the water-blocking part 2c and flows back into the water-holding part 2a.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
