TECHNICAL FIELD
[0001] The utility model belongs to the technical field of grinding disc, specifically a grinding disc for grain processing. BACKGROUND
[0002] Grinding disc is a kind of equipment for processing and grinding material, and is widely used in the fields of agriculture, food processing and the like, and is commonly used for crushing grains. The grinding disc system is usually composed of two discs, i.e. a driving disc (rotating) and a fixed disc (stationary). When the material enters the grinding disc, it is squeezed, rubbed and sheared along with the rotation of the driving disc, and is gradually pushed to the outer edge of the grinding disc. The material is finally crushed to the required particle size through the action of the grooves and lines on the surface of the grinding disc, and is discharged from the outer edge of the grinding disc.
[0003] Under the condition of long-time and high-load work, a large amount of heat is generated when the grinding disc grinds the material by friction. The existing grinding disc does not have an effective heat dissipation design, and the heat will accumulate inside the grinding disc, resulting in an increase in the surface temperature of the grinding disc. The excessively high temperature will cause the quality of the material to decrease, especially for temperature-sensitive materials such as grains with high fat content, which will be deteriorated due to overheating. Therefore, the utility model provides a grinding disc for grain processing. CONTENT OF THE UTILITY MODEL
[0004] In order to solve the problem that a large amount of heat is generated when the grinding disc grinds the material by friction under the condition of long-time and high-load work, the existing grinding disc does not have an effective heat dissipation design, and the heat will accumulate inside the grinding disc, resulting in an increase in the surface temperature of the grinding disc. The excessively high temperature will cause the quality of the material to decrease, especially for temperature-sensitive materials such as grains with high fat content, which will be deteriorated due to overheating. The utility model provides the following technical scheme: a grinding disc for grain processing, comprising a material receiving disc, a discharge port is arranged on the material receiving disc, a lower grinding disc is arranged on the material receiving disc, an upper grinding disc is arranged on the lower grinding disc, an air duct is arranged in the upper grinding disc, heat dissipation fins are arranged on the upper grinding disc, a fixed support is arranged above the upper grinding disc, the bottom of the fixed support on both sides is connected to the material receiving disc, a rotary motor is arranged at the bottom of the horizontal part of the fixed support, the output end of the rotary motor is connected to the upper grinding disc through a connecting piece, and a feeding port is arranged on the upper grinding disc.
[0005] Preferably, the air duct has an inlet and an outlet, the inlet is arranged at the center of the upper grinding disc, and the outlet is arranged at the outer edge of the upper grinding disc. The centrifugal force generated when the upper grinding disc rotates is used to suck air from the inlet and push it to the outer edge. The air flow generated by rotation effectively carries away heat and prevents heat accumulation.
[0006] Preferably, the air duct is spiral-shaped. The spiral shape further prolongs the flow path of the air, so that the air stays in the air duct for a longer time, increases the opportunity for heat exchange, and enhances the heat dissipation effect.
[0007] Preferably, the plurality of heat dissipation fins are arranged in a circular pattern on the top surface of the upper millstone, the plurality of heat dissipation fins gradually increase in length from the center to the edge, and the plurality of heat dissipation fins are made of aluminum or copper. The radial heat dissipation fins can maximize the coverage of the surface of the upper millstone and effectively improve the heat dissipation efficiency by increasing the surface area.
[0008] Preferably, the side edge of the upper millstone is provided with a material sweeping mechanism, and the material sweeping mechanism comprises a support plate, and the bottom of the support plate is provided with bristles. This ensures that the material does not accumulate on the outer edge of the millstone due to centrifugal force during the rotation of the millstone, and ensures smooth discharge of the material.
[0009] Preferably, the lower millstone and the upper millstone are made of aluminum alloy, stainless steel or copper alloy, and have high thermal conductivity and wear resistance.
[0010] Compared with the prior art, the utility model has the beneficial effects that:
[0011] When working, the upper millstone is driven to rotate by the rotary motor, the material enters between the upper and lower millstones through the feeding port, and the material is gradually ground into fine particles with the rotation of the upper millstone. When the upper millstone rotates at high speed, the air inlet of the air duct inhales external cold air through centrifugal force, and the cold air flows outward along the inside of the upper millstone through the spiral air duct. In the process of air flow, the air duct contacts the inner wall of the upper millstone to take away heat. The heat dissipation fins further increase the contact area of air and the millstone to help air absorb and dissipate heat. The ground material enters the receiving disc and is automatically discharged through the discharge port, effectively preventing the millstone from overheating during long-time high-speed operation, solving the problem of temperature rise of the existing millstone equipment due to poor heat dissipation, and preventing overheating and deterioration of grains with high fat content.
