Description

TECHNICAL FIELD

[0001] The patent application belongs to the technical field of cooling equipment for speed reducer, and particularly relates to a cooling and heat dissipation device for a mine-used conveying belt speed reducer. BACKGROUND

[0002] In summer, it is not only dry and hot, but also time is tight and the task is heavy in order to complete the production target on schedule. The belt material amount of the whole conveying machine is about 8000 t / h, which leads to a relatively high overall temperature of the speed reducer, and the temperature is about 75-90℃. When the temperature of the speed reducer reaches 80℃, the temperature sensor will alarm and trigger the protection mechanism, resulting in shutdown of the whole production line. Therefore, cooling treatment is urgently needed. During the operation of the speed reducer, friction will be generated due to the internal gear meshing and bearing rotation, which will be converted into heat energy to increase the temperature of the speed reducer. The excessively high temperature will accelerate the aging and deterioration of the lubricating oil, reduce its lubricating performance, increase the wear of the parts, and even cause the mechanical properties and precision of the speed reducer to decrease, thereby affecting its normal work and service life. Therefore, effective heat dissipation means are needed to control the temperature of the speed reducer and ensure its stable and reliable operation.

[0003] In the actual production process, if the temperature is relatively high, water pipes will be used to directly spray on the surface of the speed reducer body and the lubricating oil cooling air bellow for cooling, so as to ensure the normal operation of the production. If the cooling water enters the inside of the speed reducer, it will not only cause the lubricating oil to deteriorate, but also cause corrosion to the speed reducer itself and reduce the service life. The sprayed water for cooling will be splashed on the motor and the terminal of the motor, which will cause damage to the electronic components of the motor and accelerate the aging of the equipment. Artificial water spraying for cooling not only causes the equipment to be damaged faster, but also has the risk of electric shock and injury. In view of the problem that the excessively high temperature of the lubricating oil of the speed reducer causes the skeleton oil seal and bearing of the speed reducer to be replaced more frequently, the downtime is long, and the continuous work of the conveying belt is affected. The inventor has searched the current prior art and found that a speed reducer oil temperature cooling device disclosed in Chinese patent (CN212509458U) can circulate the oil in the speed reducer box through the oil outlet pipeline into the cooling device for cooling, and then the oil is pumped back into the speed reducer through the oil inlet pipeline by the oil pump. However, this kind of device mainly cools the oil in the speed reducer through the plate heat exchanger. Since the plate heat exchanger needs to input cooling liquid for heat exchange during the heat exchange process, the heat dissipation effect can be achieved. However, the device cannot input cooling liquid under any conditions, so there is a limitation. And another mechanical engineering speed reducer with oil cooling assembly and its control method like Chinese patent (CN116857344B), the cooling assembly adopts the way of spraying + air cooling oil pipe, which is actually too complex in structure. In the process of air cooling, the sprayed cooling liquid is blown off, reducing the amount of cooling liquid near the fan. The two form a functional conflict, reducing the heat dissipation efficiency. At the same time, the spraying only makes the cooling liquid stay on the oil pipe for a short time, and the heat exchange efficiency is not high. At the same time, the structure of the device increases the complexity of the cooling of the cooling liquid, but in fact it is not meaningful. In industrial applications, these cooling liquids can be naturally and quickly cooled in the open air cooling pool without increasing the cost.

[0004] Therefore, a mine conveying belt speed reducer cooling and heat dissipation device is proposed herein. SUMMARY

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts on the premise of not paying creative efforts all belong to the protection scope of the present application. Embodiment 1

[0018] As Figures 1 to 8As shown, in the prior art in the present embodiment, the inventors found that the current reduction lubricating oil temperature is too high, causing the skeleton oil seal and bearing replacement of the reduction gearbox more frequently, long downtime, affecting the continuous work of the conveyor belt. The current prior art, such as a kind of reduction machine oil temperature cooling device disclosed in Chinese patent (CN212509458U), cannot input cooling liquid under any conditions, so there is limitation; and another, such as Chinese patent (CN116857344B) reduction machine with oil cooling assembly for mechanical engineering and its control method, the structure is too complex, wind cooling + spraying forms a functional conflict, reduces the heat dissipation efficiency, and the cost is too high.

[0019] Therefore, the inventors provide a mine conveyor belt reduction machine cooling and heat dissipation device, which comprises a reduction machine 1, an oil inlet pipe 2, a reduction machine oil outlet 3, a ball valve 4, a heat dissipation mechanism 5, an oil pump 6, a filter 7, an oil pipe heat dissipation fan 8, a reduction machine oil return port 9, and a monitoring device. The reduction machine 1 is provided with a reduction machine oil outlet 3 and a reduction machine oil return port 9, respectively. The reduction machine oil outlet 3 is connected to the heat dissipation mechanism 5, the oil pump 6, the filter 7, the oil pipe heat dissipation fan 8, and the reduction machine oil return port 9 in sequence through the oil inlet pipe 2. Ball valves 4 are installed on the oil inlet end and the oil outlet end of the heat dissipation mechanism 5. The monitoring device is installed in the heat dissipation mechanism 5. The heat dissipation mechanism 5 further comprises a heat dissipation box 10, a heat exchange medium, a heat dissipation disc type oil pipe, and a manually assembled and separated heat dissipation structure. The heat dissipation box 10 is provided with replaceable heat exchange medium. The heat dissipation disc type oil pipe is immersed in the heat exchange medium. The front and rear ends of the heat dissipation disc type oil pipe are connected to the oil inlet end and the oil outlet end of the heat dissipation mechanism 5 through the main pipe 18. The heat dissipation disc type oil pipe is provided with a manually assembled and separated heat dissipation structure.

[0020] The effect is that the device can greatly improve the heat dissipation efficiency by dividing the oil in the single main pipe 18 into multiple groups and completely immersing it in the heat exchange medium for heat dissipation, compared with the current single oil pipe. When in use, the manually adjustable rotating wheel 31 can be manually rotated to drive the lead screw 26 to rotate clockwise or counterclockwise, thereby driving the base frame 22 above it to move up and down or in the opposite direction through the opposite threads 27, so as to cover or move away from the disc type pipe 19 with the upper heat dissipation fin group 20 and the lower heat dissipation fin group 21. In this way, the user can cooperate with the monitoring device to simply and quickly cool the oil pipe for different use scenarios (such as normal operation and urgent operation) and use environments (such as normal temperature weather and extreme weather), thereby expanding the application range. At the same time, the structure is simple, the materials are not complex, and the cost is low, which is suitable for industrial application.

[0021] At the same time, the semicircular edge groove 32 in the device can increase the contact area with the outside of the disc-shaped fine tube 19 through the edge on the groove body, so as to better absorb the heat of the oil flowing in the disc-shaped fine tube 19, and the through hole 33 on the heat dissipation fin can flow the heat exchange medium, thereby improving the heat exchange efficiency.

[0022] The temperature sensor 34 on the oil inlet end and the oil outlet end of the device can detect the oil pipe temperature in real time, and the liquid level sensor 35 can detect the liquid level in the tank in real time, thereby feeding back to the control panel for the user to visualize, and facilitating the user to program and adjust according to the corresponding data, thereby improving the heat exchange efficiency and precision.

The tank bracket 16 is installed on the bottom of the heat dissipation tank 10. When the structure is applied, the heat exchange medium cooling pool (not shown in the figure) outside can be connected with the heat dissipation tank 10 through the liquid inlet 11, the liquid outlet 12, the electromagnetic valve 13, and the pump body (not shown in the figure), so as to facilitate the recycling of the heat exchange medium. The design of the electromagnetic valve 13 can facilitate the user to control the circulating flow rate of the heat exchange medium according to the temperature of the oil inlet end and the oil outlet end of the heat dissipation mechanism 5.

[0024] Further, the dustproof tank cover 14 is installed with a tank heat dissipation fan 17. This structure not only can air-cool the heat dissipation tank 10 and the heat exchange medium therein, but also can blow away the dust floating into the tank through the wind power blown out of the observation heat dissipation hole, thereby realizing the effect of heat dissipation and dust prevention. Embodiment 3

[0025] As shown in Figures 1 to 8 Based on the above embodiment, the heat exchange medium can be water or ethylene glycol-based coolant. Under normal working conditions, low-cost water can be used as the heat exchange medium. In extreme weather (such as ultra-high temperature or ultra-low temperature), ethylene glycol-based coolant can be used. It is the most common coolant type currently used in automobiles, with an ice point of below -60°C, a high boiling point, comprehensive performance, and relatively low cost. Embodiment 4

Compared with the current single oil transfer coil pipe, this can greatly improve the heat dissipation efficiency. Example 5
