Abstract
Description
Technical Field
[0001] This utility model relates to the field of micronized wax grinding and processing technology, specifically to a grinding mill for producing micronized wax. Background Technology
[0002] Paraffin wax, as an important industrial raw material, has wide applications in many fields such as candle manufacturing, packaging, cosmetics, food processing, and electrical insulation. As various industries continue to raise their requirements for the quality and performance of paraffin wax products, more stringent standards are being imposed on paraffin wax processing techniques and equipment. Among these, processing paraffin wax into a fine, uniform powder is one of the key steps to meet the needs of different application scenarios.
[0003] In traditional micronized wax grinding equipment, the moving and stationary grinding discs generate a significant amount of heat during high-speed rotation. Due to the lack of an effective cooling structure, this heat cannot dissipate quickly, causing a rapid rise in the temperature of both the moving and stationary grinding discs. When the temperature is too high, the micronized wax is prone to melting. The molten wax adheres to the surface of the grinding discs, affecting not only grinding efficiency and quality but also increasing the difficulty of cleaning and maintenance costs. Furthermore, high temperatures can also cause changes in the chemical properties of the micronized wax, affecting its subsequent performance. Utility Model Content
[0004] This utility model provides a grinding mill for producing micronized wax, which solves the technical problems in the prior art where micronized wax is easily melted or stuck due to excessively high temperature during grinding.
[0005] To solve the above problems, the present invention provides a grinding mill for producing micronized wax, which adopts the following technical solution:
[0006] The device includes a grinding chamber, a cover plate hinged to one side of the grinding chamber, a fixed grinding disc on the side of the cover plate opposite to the grinding chamber, a feed hopper on the cover plate communicating with the center of the fixed grinding disc, a rotating shaft rotatably mounted inside the grinding chamber, a movable grinding disc detachably mounted on the rotating shaft and rotating with the shaft, a mounting liner fixedly mounted on the rotating shaft, the movable grinding disc detachably mounted on the side of the mounting liner near the cover plate, a mounting platform on the outer edge of the side of the mounting liner near the movable grinding disc, a cooling chamber formed between the movable grinding disc and the mounting liner, a coolant coil in the cooling chamber, a slot on the rotating shaft allowing the coolant coil to pass through, one end of the slot communicating with the cooling chamber, and a rotary joint to prevent the coolant coil from tangling at the end of the rotating shaft away from the cover plate.
[0007] A cooling element is provided between the fixed grinding disc and the cover plate.
[0008] Furthermore, the mounting liner is provided with equidistant spiral grooves on the side opposite to the moving grinding disc, and the equidistant spiral grooves are used to limit and lock the coolant coil.
[0009] Furthermore, the slot includes a horizontal end portion and a vertical end portion, and the vertical end portion, which is perpendicular to the axis of the rotating shaft, communicates with the cooling cavity.
[0010] Furthermore, the diameter of the slot is L1, and the diameter of the rotating shaft is L2, wherein L1:L2 is 1:(3-5).
[0011] Furthermore, a connecting flange is provided at the end of the rotating shaft away from the cover plate, and the rotary joint is fixed to one end of the rotating shaft through the connecting flange.
[0012] The rotary joint includes an inlet pipe and an outlet pipe that are respectively connected to both ends of the coolant coil.
[0013] Furthermore, a pressure plate is provided on the side of the moving grinding disc away from the mounting liner, and a threaded cap for pressing the pressure plate is provided on the end of the rotating shaft away from the rotary joint.
[0014] Furthermore, the sidewall of the compression cap is provided with spaced-apart functional grooves.
[0015] Furthermore, the cooling component is a liquid cooling coil, and both ends of the liquid cooling coil are connected to the outside through cover plates.

[0017] 1. In this invention, a cooling chamber is formed between the moving grinding disc and the mounting liner, and a coolant coil is installed within the cooling chamber. The coolant circulates within the coil, directly cooling the moving grinding disc. During the grinding of micronized wax, the high-speed friction between the moving and stationary grinding discs generates a large amount of heat. This direct cooling method can quickly remove the heat, effectively reducing the temperature of the moving grinding disc and preventing problems such as melting and sticking of the micronized wax due to excessive temperature, thus ensuring the normal grinding process. A liquid-cooled coil is installed between the stationary grinding disc and the cover plate as a cooling component. Both ends of the liquid-cooled coil are connected to the outside through the cover plate, effectively cooling the stationary grinding disc. Cooling structures are provided at both the moving and stationary grinding discs, effectively reducing the high temperature generated during relative rotational grinding, preventing the micronized wax from clumping due to high temperature, and further improving the normal grinding process.
[0018] 2. In this utility model, the moving grinding disc is detachably mounted on the mounting liner. When maintenance, replacement, or cleaning of the moving grinding disc is required, simply loosen the clamping cap to easily remove the pressure plate, and then detach the moving grinding disc from the rotating shaft. This convenient and quick operation significantly reduces equipment downtime, improves maintenance efficiency, and lowers maintenance costs. The circumferentially spaced grooves on the side wall of the clamping cap provide operators with good leverage points. When tightening or loosening the clamping cap, tools such as wrenches can be used to engage the grooves, facilitating the application of torque and making operation easier and less strenuous, thus improving the operability and adaptability of the equipment.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0027] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.
[0028] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0029] An embodiment of a grinding mill for producing micronized wax provided by this utility model:
[0030] like Figures 1 to 4 As shown,
[0031] The device includes a grinding box 1, a cover plate 2 hinged to one side of the grinding box 1, a fixed grinding disc 21 on the side of the cover plate 2 opposite to the grinding box 1, a feed hopper 22 connected to the center of the fixed grinding disc 21 on the cover plate 2, a rotating shaft 3 rotatably mounted inside the grinding box 1, and a movable grinding disc 4 detachably mounted on the rotating shaft 3 and rotating with the rotating shaft 3.
[0032] The fixed grinding disc 21 has a circular groove at its center, and the bottom of the feed hopper 22 connects to the circular groove. After the cover plate 2 is pressed and fixed onto the grinding box 1, the distance between the fixed grinding disc 21 and the moving grinding disc 4 is 1mm. The material entering from the feed hopper 22 will enter between the fixed grinding disc 21 and the moving grinding disc 4, and the material will be ground by the rotation of the moving grinding disc 4.
[0033] In this embodiment, a mounting liner 5 is fixedly provided on the rotating shaft 3, and the moving grinding disc 4 is detachably provided on the side of the mounting liner 5 close to the cover plate 2. A mounting platform 51 is provided on the outer edge of the side of the mounting liner 5 close to the moving grinding disc 4. The moving grinding disc 4 is connected to the mounting platform 51 by bolts. A cooling cavity 52 is formed between the moving grinding disc 4 and the mounting liner 5, and a coolant coil 53 is provided in the cooling cavity 52.
[0034] A cooling chamber 52 is formed between the moving grinding disc 4 and the mounting liner 5, and a coolant coil 53 is installed in the cooling chamber 52. The coolant circulates in the coil, which can directly cool the moving grinding disc 4. During the grinding of micronized wax, the high-speed friction between the moving grinding disc 4 and the stationary grinding disc 21 generates a large amount of heat. This direct cooling method can quickly remove the heat, effectively reducing the temperature of the moving grinding disc 4 and preventing problems such as melting and sticking of the micronized wax due to excessive temperature, thus ensuring the quality of the micronized wax grinding.
[0035] A cooling element is provided between the fixed grinding disc 21 and the cover plate 2.
[0036] The cooling component is a liquid cooling coil, and both ends of the liquid cooling coil are connected to the outside through cover plate 2.
[0037] Cooling structures are provided at both the moving grinding disc 4 and the fixed grinding disc 21, which can effectively reduce the high temperature generated during relative rotation grinding, thereby avoiding the agglomeration of micro powder wax caused by high temperature and improving the normal grinding of micro powder wax.
[0038] Among them, the mounting liner 5 is provided with equidistant spiral grooves 54 on the side opposite to the moving grinding disc 4. The equidistant spiral grooves 54 are used to limit and hold the coolant coil 53.
[0039] The coolant coil 53 is positioned and secured by the equidistant spiral grooves 54, preventing it from being squeezed by centrifugal force during the high rotation of the moving grinding disc 4. Displacement or squeezing of the coolant coil 53 could impede coolant flow, affecting cooling efficiency and potentially causing system failure. The positioning function of the equidistant spiral grooves 54 ensures the stability and reliability of the cooling system.
[0040] In this embodiment, the rotating shaft 3 is provided with a slot 31 that allows the coolant coil 53 to pass through. One end of the slot 31 is connected to the cooling chamber 52, and the end of the rotating shaft 3 away from the cover plate 2 is provided with a rotary joint 32 to prevent the coolant coil 53 from getting tangled. The slot 31 includes a horizontal end portion and a vertical end portion, and the vertical end portion, which is perpendicular to the axial direction of the rotating shaft 3, is connected to the cooling chamber 52.
[0041] The slot 31 and the rotary joint 32 work together to form a complete coolant delivery system. The slot 31 provides a channel for the coolant to flow inside the rotating shaft 3, while the rotary joint 32 ensures the stable circulation of the coolant during the rotation of the rotating shaft 3. The two work together to ensure that the coolant can efficiently and stably cool the relevant components, thereby improving the overall performance and operational stability of the equipment.
[0042] The end of the rotating shaft 3 away from the cover plate 2 is provided with a connecting flange 33, and the rotary joint 32 is fixed to one end of the rotating shaft 3 through the connecting flange 33.
[0043] The rotary joint 32 includes an inlet pipe and a return pipe that are respectively connected to both ends of the coolant coil 53.
[0044] Specifically, the diameter of the slot 31 is L1, and the diameter of the rotating shaft 3 is L2. In this embodiment, the diameter L2 of the rotating shaft 3 is 3.5cm, and the diameter L1 of the slot 31 is 1cm.
[0045] This structure is designed to ensure the strength of the shaft 3 while providing sufficient space for the coolant coil 53 to pass through.
[0046] In this embodiment, a pressure plate 6 is provided on the side of the moving grinding disc 4 away from the mounting liner 5, and a pressure cap 7 with a threaded connection and used to press the pressure plate 6 is provided on the end of the rotating shaft 3 away from the rotary joint 32.
[0047] The side wall of the compression cap 7 is provided with spaced-apart functional grooves 71.
[0048] The combination of the pressure plate 6 and the clamping cap 7 securely helps to press the moving grinding disc 4 onto the mounting liner 5. The clamping cap 7 is threaded to the rotating shaft 3, and this connection provides reliable fastening force, ensuring that the moving grinding disc 4 will not loosen or shift during high-speed rotation, thus guaranteeing the stability and accuracy of the grinding process.
[0049] The circumferentially spaced grooves on the side wall of the clamping cap 7 provide operators with good leverage points. When tightening or loosening the clamping cap, tools such as wrenches can be used to engage the grooves to easily apply torque, making the operation easier and less strenuous.
