Description

Technical Field

[0001] This utility model patent belongs to the technical field of speed reducer cooling equipment, specifically relating to a cooling and heat dissipation device for a mining conveyor belt speed reducer. Background Technology

[0002] Summer is not only dry and hot, but also time-sensitive and demanding. To meet production targets on schedule, the entire conveyor belt carries approximately 8000 tons of material per hour, causing the reducer to reach a high temperature of around 75℃-90℃. When the reducer temperature reaches 80℃, the temperature sensor will alarm, triggering the protection mechanism and causing the entire production line to shut down. Therefore, cooling measures are urgently needed. During operation, the gear reducer generates friction due to internal gear meshing and bearing rotation, which is converted into heat energy, causing the reducer temperature to rise. Excessive temperature accelerates the aging and deterioration of the lubricating oil, reducing its lubricating performance, increasing component wear, and may even lead to a decline in the reducer's mechanical performance and precision, affecting its normal operation and service life. Therefore, effective heat dissipation methods are needed to control the reducer's temperature and ensure its stable and reliable operation.

[0003] In actual production, if the temperature is too high, water is sprayed directly onto the reducer body and the surface of the lubricating oil cooling box to cool them down and ensure normal production. If cooling water enters the reducer, it will not only cause the lubricating oil to deteriorate, but also corrode the reducer itself, reducing its service life; the cooling spray water splashed on the motor and its terminals will damage the motor's electronic components and accelerate equipment aging; manual water spraying for cooling not only accelerates equipment damage, but also poses a risk of electric shock. To address the problem of excessively high lubricating oil temperature in gearboxes, which leads to frequent replacements of gearbox oil seals and bearings, prolonged downtime, and disruption of continuous conveyor belt operation, the inventors searched existing technologies and found a gearbox oil temperature cooling device disclosed in Chinese Patent (CN212509458U). This device cools the oil inside the gearbox through an oil outlet pipe into the cooling device, and then pumps the oil back into the gearbox through an oil inlet pipe, repeating the cycle. However, this type of device mainly uses a plate heat exchanger to cool the oil inside the gearbox. Since plate heat exchangers require the simultaneous input of coolant for heat exchange to achieve a cooling effect, and the device cannot input coolant under all conditions, it has limitations. Another example is the Chinese patent (CN116857344B) for a mechanical engineering reducer and its control method with an oil cooling component. The cooling component uses a spray + air-cooled oil pipe structure that is actually too complex. During the air-cooling process, the sprayed coolant is blown off course, reducing the amount of coolant reaching the area near the fan. This creates a functional conflict and reduces the heat dissipation efficiency. Furthermore, the spray only allows the coolant to remain on the oil pipe for a short time, and its heat exchange efficiency is not high. At the same time, the device increases the structural complexity for cooling the coolant, but it is not very meaningful in practice. In industrial applications, the coolant can be naturally and quickly dissipated by simply placing it in an open-air cooling pool, without adding unnecessary costs.

[0004] Therefore, this paper proposes a cooling and heat dissipation device for a mining conveyor belt reducer. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to provide a cooling and heat dissipation device for a mining conveyor belt reducer.

The left side of the upper left main pipe inside the heat dissipation box is detachably connected to the oil inlet end inside the heat dissipation mechanism. The right side of the upper left main pipe inside the heat dissipation box is connected to the front end of several disc-shaped thin pipes. The right side of the lower right main pipe inside the heat dissipation box is detachably connected to the oil outlet end inside the heat dissipation mechanism.

[0011] Preferably, the manually assembleable and detachable heat dissipation structure further includes an upper heat sink assembly, a lower heat sink assembly, a base frame, a positioning groove, a positioning slide rail, screw holes, a lead screw, opposing threads, a limit clip, a synchronous pulley, a synchronous belt, and a manually adjustable wheel. The upper and lower heat sink assemblies are respectively located on the upper and lower sides of each horizontal section of the disc-shaped thin tube, and base frames are installed at both ends of the upper and lower heat sink assemblies. The base frames on both sides of the heat dissipation box are slidably mounted on the positioning slide rails on both sides of the heat dissipation box through the positioning grooves on their sides. Screw holes are provided at the center of the base frames at both ends of the upper and lower heat sink assemblies. The lead screws are rotatably installed on the front and rear sides inside the heat sink. Each lead screw has opposing threads on the upper and lower sides of each horizontal section of the disc-shaped tube. The upper and lower screw holes in the upper and lower bases at one end correspond to the opposing threads on the lead screw at the same horizontal position. Limiting clips are provided on the lead screw in the middle and at the upper and lower ends of the opposing threads to prevent the bases from slipping out of the opposing threads. The tops of the lead screws on the front and rear sides of the heat sink extend through the dust cover and above it.

[0015] The beneficial effects of this utility model are: This device uses several disc-shaped thin tubes to divide the oil in the original single main pipe into multiple groups and completely immerse it in the heat exchange medium for heat dissipation. Compared with the current single oil delivery coil, this can greatly improve the heat dissipation efficiency.

At the same time, the through holes on the heat sink can allow the heat exchange medium to flow, thereby improving the heat exchange efficiency. The temperature sensors at the oil inlet and outlet of the device can detect the oil pipe temperature in real time, and the liquid level sensor can detect the liquid level in the tank in real time. The data is then fed back to the control panel for visualization by the user, which also makes it easier for the user to program and adjust according to the corresponding data, thereby improving the heat exchange efficiency and accuracy.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example 1

[0018] like Figures 1 to 8As shown, the existing technology in this embodiment has the following problems: The inventors have found that the current technology, such as the gearbox oil temperature being too high, which causes frequent replacement of the gearbox's skeleton oil seal and bearings, long downtime, and affects the continuous operation of the conveyor belt, has limitations. For example, the gearbox oil temperature cooling device disclosed in Chinese Patent (CN212509458U) cannot input coolant under all conditions. On the other hand, the mechanical engineering gearbox and its control method with oil cooling components in Chinese Patent (CN116857344B) has an overly complex structure. The air cooling + spray cooling functions conflict, reducing heat dissipation efficiency and increasing costs.

[0019] Therefore, the inventor provides a cooling and heat dissipation device for a mining conveyor belt reducer, including a reducer 1, an oil inlet pipe 2, a reducer oil outlet 3, a ball valve 4, a heat dissipation mechanism 5, an oil pump 6, a filter 7, an oil pipe cooling fan 8, a reducer oil return port 9, and a monitoring device. The reducer 1 is respectively equipped with a reducer oil outlet 3 and a reducer oil return port 9. The reducer oil outlet 3 is connected in sequence to the heat dissipation mechanism 5, the oil pump 6, the filter 7, the oil pipe cooling fan 8, and the reducer oil return port 9 via the oil inlet pipe 2. The outer side of the heat dissipation mechanism 5... Ball valves 4 are installed on the oil inlet and oil outlet respectively. The monitoring device is installed in the heat dissipation mechanism 5. The heat dissipation mechanism 5 also includes a heat dissipation box 10, a heat exchange medium, a heat dissipation disc-shaped oil pipe, and a heat dissipation structure that can be manually assembled and disassembled. The heat dissipation box 10 is provided with a replaceable heat exchange medium. The heat exchange medium is immersed in the heat dissipation disc-shaped oil pipe, and the front and rear ends of the heat dissipation disc-shaped oil pipe are respectively connected to the oil inlet and oil outlet on the inner side of the heat dissipation mechanism 5 through the main pipe 18. The heat dissipation disc-shaped oil pipe is equipped with a heat dissipation structure that can be manually assembled and disassembled.

[0020] Its effect is that the device divides the oil in the original single main pipe 18 into multiple groups and completely immerses it in the heat exchange medium through several disc-shaped thin tubes 19 to dissipate heat. Compared with the current single oil delivery coil, this can greatly improve the heat dissipation efficiency. In use, the manual adjustment wheel 31 can be manually rotated to drive the lead screw 26 to rotate clockwise or counterclockwise. This, in turn, drives the base frame 22 on the opposite thread 27 to move up and down in opposite directions or in opposite directions. This allows the upper heat sink assembly 20 and the lower heat sink assembly 21 to cover or move away from the disc-shaped thin tube 19. This makes it convenient for users to use the monitoring device to perform simple and rapid heat dissipation and cooling of the oil pipe in different usage scenarios (such as normal operation and emergency operation) and usage environments (such as normal temperature weather and extreme weather), thus expanding its application range. At the same time, the structure is simple, uses uncomplicated materials, and has low cost, making it suitable for industrial applications.

[0021] Meanwhile, the semi-circular edging groove 32 in the device can increase the contact area with the outside of the disc-shaped tube 19 by edging the groove body, thereby better absorbing the heat of the oil flowing through the disc-shaped tube 19. At the same time, the through holes 33 on the heat sink can allow the heat exchange medium to flow, thereby improving the heat exchange efficiency.

[0022] The temperature sensor 34 on the oil inlet and oil outlet 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. The data is then fed back to the control panel for visualization by the user, which also makes it easier for the user to program and adjust according to the corresponding data, thereby improving the heat exchange efficiency and accuracy. Example 2

[0023] like Figures 1 to 8 As shown, based on the above embodiment, the heat sink 10 also includes an inlet 11, an outlet 12, a solenoid valve 13, a dust cover 14, a bracket 15, and a frame 16. The inlet 11 and outlet 12 are respectively installed on the upper right side and lower bottom side of the heat sink 10, and a solenoid valve 13 is installed on both the inlet 11 and outlet 12. The solenoid valve 13 is electrically connected to the monitoring device. The top of the heat sink 10 is equipped with a dust cover 14 through the bracket 15, and an observation and heat dissipation hole is provided between the top of the heat sink 10 and the dust cover 14. The frame 16 is installed at the bottom of the heat sink 10. When this structure is applied, the external heat exchange medium cooling pool (not shown in the figure) can be connected to the heat sink 10 through the inlet 11, outlet 12, solenoid valve 13, and pump body (not shown in the figure), which facilitates the recycling of the heat exchange medium. The design of the solenoid valve 13 allows the user to control the circulation rate of the heat exchange medium according to the temperature of the oil inlet and outlet of the heat dissipation mechanism 5.

[0024] Furthermore, a cooling fan 17 is installed on the dust cover 14; this structure can not only provide air cooling for the heat dissipation box 10 and the heat exchange medium therein, but also blow away the dust drifting into the box by the air blown out from the observation vent, thereby achieving the function of heat dissipation and dust prevention. Example 3

[0025] like Figures 1 to 8 As shown in the above embodiments, the heat exchange medium can be set as 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, which is the most common type of coolant currently used in automobiles. It has a freezing point of -60°C or lower, a high boiling point, comprehensive performance, and a relatively low cost. Example 4

[0026] like Figures 1 to 8As shown, based on the above embodiment, the heat dissipation coil-type oil pipe also includes a main pipe 18 and several coil-shaped thin pipes 19. The main pipe 18 is horizontally placed on the upper left and lower right sides inside the heat dissipation box 10, with both ends of the main pipe 18 facing the front and rear sides of the heat dissipation box 10 respectively. The left side of the upper left main pipe 18 inside the heat dissipation box 10 is detachably connected to the oil inlet end inside the heat dissipation mechanism 5. The right side of the upper left main pipe 18 inside the heat dissipation box 10 is connected to the front end of several coil-shaped thin pipes 19. The right side of the lower right main pipe 18 inside the heat dissipation box 10 is detachably connected to the oil outlet end inside the heat dissipation mechanism 5. The right side of the lower right main pipe 18 inside the heat dissipation box 10 is connected to the rear end of several coil-shaped thin pipes 19. This structure divides the oil in the original single main pipe 18 into multiple groups for heat dissipation through several coil-shaped thin pipes 19, which can greatly improve the heat dissipation efficiency compared to the current single oil delivery coil. Example 5

[0027] like Figures 1 to 8 As shown, based on the above embodiment, the manually assembleable and separable heat dissipation structure also includes an upper heat sink assembly 20, a lower heat sink assembly 21, a base frame 22, a positioning groove 23, a positioning slide rail 24, a screw hole 25, a lead screw 26, opposing threads 27, a limit clip 28, a synchronous pulley 29, a synchronous belt 30, and a manually adjustable wheel 31. The upper heat sink assembly 20 and the lower heat sink assembly 21 are respectively arranged on the upper and lower sides of each horizontal section of the disc-shaped thin tube 19, and the base frame 22 is installed at both the front and rear ends of the upper heat sink assembly 20 and the lower heat sink assembly 21. The base frames 22 on the front and rear sides inside the heat dissipation box 10 are slidably mounted on the positioning slide rails 24 on the front and rear sides inside the heat dissipation box 10 through the positioning grooves 23 on their sides. The center of the base frame 22 at both ends of the upper heat sink assembly 20 and the lower heat sink assembly 21 is provided with The screws 26 are rotatably installed on the front and rear sides inside the heat sink 10 with screw holes 25. Each screw 26 is provided with opposing threads 27 on the upper and lower sides of each group of horizontal sections of the disc-shaped thin tube 19. The upper and lower screw holes 25 in the upper and lower base frames 22 at one end correspond to the opposing threads 27 on the screw 26 at the same horizontal position. The middle and the upper and lower ends of the opposing threads 27 are respectively provided with limit clips 28 to prevent the base frame 22 from slipping out of the opposing threads 27. The top ends of the screws 26 on the front and rear sides of the heat sink 10 pass through the dust cover 14 and extend above it. The top end of the screw 26 on the front side of the heat sink 10 is connected to a manual adjustment wheel 31. The screw 26 above the dust cover is also provided with a synchronous wheel 29, and the synchronous wheels 29 on the front and rear sides are connected by a synchronous belt 30. When in use, this structure can be manually adjusted by turning the manual adjustment wheel 31, which drives the lead screw 26 to rotate clockwise or counterclockwise. This, in turn, drives the base frame 22 on the opposite thread 27 to move up and down in opposite directions or in opposite directions. This allows the upper heat sink assembly 20 and the lower heat sink assembly 21 to cover or move away from the disc-shaped thin tube 19. This makes it easy for users to use the monitoring device to cool the oil pipe quickly and easily, depending on the usage scenario (such as normal operation or emergency operation) and the usage environment (such as normal temperature weather or extreme weather). At the same time, the structure is simple and uses uncomplicated materials, making it suitable for industrial applications.

[0028] Furthermore, the heat sinks in the upper heat sink assembly 20 and the lower heat sink assembly 21 are provided with semi-circular edging grooves 32 corresponding to the outer diameter of each disc-shaped thin tube 19, and the heat sinks are also provided with a number of through holes 33 for the flow of heat exchange medium. The semi-circular edging grooves 32 in this structure can increase the contact area with the outside of the disc-shaped thin tube 19 by edging the groove body, thereby better absorbing the heat of the oil flowing in the disc-shaped thin tube 19. At the same time, the through holes 33 on the heat sink can allow the flow of heat exchange medium, thereby improving the heat exchange efficiency. Example 6

[0029] like Figures 1 to 8 As shown, based on the above embodiment, the monitoring device also includes a control panel, a temperature sensor 34, and a liquid level sensor 35. The control panel is installed on the front side of the heat exchange box 10. The temperature sensor 34 is installed on the oil inlet and oil outlet sides inside the heat exchange box 10, and the contact surface between the temperature sensor 34 and the heat exchange medium is coated with a waterproof layer (not shown in the figure). The liquid level sensor 35 is located on the upper side of the heat exchange box 10. In this structure, the temperature sensor 34 on the oil inlet and oil outlet sides can detect the oil pipe temperature in real time, and the liquid level sensor 35 can detect the liquid level in the box in real time, and then feed it back to the control panel for visualization by the user. It is also convenient for the user to program and adjust according to the corresponding data, thereby improving the heat exchange efficiency and accuracy.

[0030] Furthermore, the control panel also includes a display 36, a processor 37, a control button 38, a power interface 39, and an alarm 40. The processor 37 is electrically connected to the display 36, control button 38, power interface 39, alarm 40, temperature sensor 34, liquid level sensor 35, oil pump 6, filter 7, oil pipe cooling fan 8, solenoid valve 13, pump body, and housing cooling fan 17. The power interface 39 provides power to the processor 37, display 36, control button 38, power interface 39, alarm 40, temperature sensor 34, liquid level sensor 35, oil pump 6, filter 7, oil pipe cooling fan 8, solenoid valve 13, pump body, and housing cooling fan 17 by connecting to a power source.

[0031] The working principle of this utility model: The device uses several disc-shaped thin tubes 19 to divide the oil in the original single main pipe 18 into multiple groups and completely immerse it in the heat exchange medium for heat dissipation. Compared with the current single oil delivery coil, this can greatly improve the heat dissipation efficiency. In use, the manual adjustment wheel 31 can be manually rotated to drive the lead screw 26 to rotate clockwise or counterclockwise. This, in turn, drives the base frame 22 on the lead screw 26 to move up and down in opposite directions or in opposite directions through the opposing threads 27. This allows the upper heat sink assembly 20 and the lower heat sink assembly 21 to cover or move away from the disc-shaped thin tube 19. This makes it convenient for users to use the monitoring device to perform simple and rapid heat dissipation and cooling of the oil pipe in different usage scenarios (such as normal operation and emergency operation) and usage environments (such as normal temperature weather and extreme weather), thus expanding its application range. At the same time, the structure is simple, uses uncomplicated materials, and has low cost, making it suitable for industrial applications.
