Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, and more specifically, to a coal mill lubricating oil cooler. Background Technology

[0002] A coal mill is a machine that crushes and grinds coal into pulverized coal. It is an important auxiliary equipment for pulverized coal boilers. The coal grinding process is the process of crushing coal and continuously increasing its surface area. Coal is ground into pulverized coal in a coal mill mainly through three methods: crushing, impact crushing, and grinding.

[0003] During the operation of a coal mill, lubricating oil is added to the gears to improve transmission efficiency and prevent wear and rust. This extends the service life of the equipment. However, the high-speed friction between the gears during operation generates a large amount of heat, which can cause the lubricating oil to deteriorate and crack, leading to emulsification and affecting its lubrication effect. This necessitates frequent oil replacement and replenishment by operators, increasing maintenance costs and causing inconvenience to their daily work. Therefore, improvements are needed.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 6 As shown, this utility model provides a coal mill lubricating oil cooler, comprising:

[0030] Hopper 1, with a cooling pipe 4 fixedly sleeved inside the hopper 1, and a discharge pipe 6 fixedly sleeved at the right end of the cooling pipe 4;

[0031] A cooling mechanism is installed on the outer surface of the cooling pipe 4;

[0032] The cooling mechanism includes a front water tank 2 and a rear water tank 3. The interior of both the front water tank 2 and the rear water tank 3 is fixedly sleeved with the outer surface of the cooling pipe 4. A fixed pipe 5 is fixedly sleeved inside the front water tank 2. The cooling pipe 4 is located inside the fixed pipe 5. The right end of the fixed pipe 5 is fixedly sleeved with the interior of the rear water tank 3. A circulation pipe 7 is fixedly sleeved at the bottom of the front water tank 2 and the rear water tank 3. Heat dissipation fins 9 are fixedly sleeved on the outer surface of both the fixed pipe 5 and the circulation pipe 7.

[0033] When the high-temperature lubricating oil enters the cooling pipe 4 from the hopper 1, the cooling pipe 4 absorbs the heat of the high-temperature lubricating oil. At the same time, the coolant between the cooling pipe 4 and the fixed pipe 5 absorbs the heat of the cooling pipe 4 and conducts it to the fixed pipe 5. Then, the heat absorbed by the fixed pipe 5 is absorbed by the heat dissipation fins 9 and dissipated through convection. When the coolant enters the circulation pipe 7, the coolant will have a certain temperature. At this time, the heat dissipation fins 9 will absorb and dissipate the heat of the coolant through the circulation pipe 7 to ensure the cooling effect of the lubricating oil.

[0034] Among them, the outer surface of the circulation pipe 7 is fixedly sleeved with a water pump 8, and the outer surface of the water pump 8 is fixedly sleeved with the inside of the heat dissipation fin 9.

[0035] When water pump 8 is running, the coolant will flow, thus enabling efficient heat absorption.

[0036] Among them, a drive motor 10 is fixedly installed on the outer surface of the hopper 1, and a rotating shaft 11 is fixedly sleeved on the other end of the output shaft of the drive motor 10. An auger 12 is fixedly sleeved on the outer surface of the rotating shaft 11, and the outer surface of the auger 12 is movably sleeved with the interior of the cooling pipe 4.

[0037] When the drive motor 10 is running, the rotating shaft 11 will drive the auger 12 to rotate. Due to the design of the auger 12, when the auger 12 rotates, it will be able to drive the high-temperature lubricating oil inside the hopper 1 to the inside of the cooling pipe 4.

[0038] The front water tank 2 and the rear water tank 3 are both fixedly installed with connecting blocks 13. A long rod 14 is fixedly sleeved inside the connecting block 13, and a base 15 is fixedly sleeved on the outer surface of the long rod 14.

[0039] Due to the design of the base 15, the long rod 14 and the connecting block 13, the cooler can be well supported, allowing it to be placed stably on the ground.

[0040] The base 15 has a reinforcing rod 16 fixedly sleeved on its outer surface. The reinforcing rod 16 is made of metal.

[0041] The design of the reinforcing rod 16 will strengthen the overall structure of the base 15.

[0042] The base 15 has a base plate 17 fixedly installed inside, a fixing block 18 fixedly installed at the top of the base plate 17, a short shaft 19 movably sleeved inside the fixing block 18, and a driven wheel 20 fixedly sleeved on the outer surface of the short shaft 19.

[0043] Since the interior of the fixed block 18 is movably sleeved with the outer surface of the short shaft 19, when the driven wheel 20 rotates, it will drive the short shaft 19 to rotate around the sleeved part with the fixed block 18 as the axis.

[0044] A bracket 21 is fixedly installed on the left side of the top of the base plate 17. A power motor 22 is fixedly installed on the top of the bracket 21. A rotating shaft 23 is fixedly sleeved on the other end of the output shaft of the power motor 22. The bottom end of the outer surface of the rotating shaft 23 is movably sleeved with the inside of the fixed block 18.

[0045] When the power motor 22 is running, the rotating shaft 23 will rotate.

[0046] Among them, a drive wheel 24 is fixedly sleeved on the outer surface of the rotating shaft 23, and the drive wheel 24 is connected to the driven wheel 20 through the transmission belt 25.

[0047] When the rotating shaft 23 rotates, the drive wheel 24 will rotate under the drive of the rotating shaft 23. At this time, the drive wheel 24 will drive the driven wheel 20 to rotate through the transmission belt 25.

[0048] Among them, a rotating wheel 26 is movably connected to the outer surface of the transmission belt 25, a vertical shaft 27 is fixedly sleeved inside the rotating wheel 26, the bottom end of the outer surface of the vertical shaft 27 is movably sleeved inside the fixed block 18, and a fan blade 28 is fixedly sleeved at the top end of the outer surface of the vertical shaft 27.

[0049] Since the outer surface of the transmission belt 25 is movably connected to the outer surface of the rotating wheel 26, when the transmission belt 25 moves, it will drive the vertical shaft 27 to rotate around the point where it is connected to the fan blade 28 through the rotating wheel 26. At this time, the fan blade 28 will rotate under the drive of the vertical shaft 27. The fan blade 28 will blow air onto the heat dissipation fins 9, thereby enhancing the heat dissipation effect of the heat dissipation fins 9.

[0050] The outer surface of the transmission belt 25 is tensioned and connected to a tensioning wheel 29, and a round shaft 30 is fixedly sleeved inside the tensioning wheel 29. The bottom end of the outer surface of the round shaft 30 is movably sleeved with the inside of the fixing block 18.

[0051] Because the tensioning wheel 29 is internally and movably connected to the fixed block 18, the round shaft 30 can drive the tensioning wheel 29 to rotate around the connection point with the fixed block 18. When the transmission belt 25 moves, it will drive the round shaft 30 to rotate. Due to the design of the round shaft 30, the contact area between the transmission belt 25 and the driven wheel 20, the driving wheel 24 and the rotating wheel 26 can be increased, thereby ensuring the stability of the transmission of the transmission belt 25.

[0052] Working principle and usage process of this utility model:

[0053] When the high-temperature lubricating oil enters the hopper 1, the operator starts the drive motor 10. The rotating shaft 11 then drives the auger 12 to rotate. Due to the design of the auger 12, when the auger 12 rotates, it can drive the high-temperature lubricating oil inside the hopper 1 to move into the cooling pipe 4. When the high-temperature lubricating oil enters the cooling pipe 4, the lubricating oil will conduct heat to the pipe wall of the cooling pipe 4. At this time, the operator starts the water pump 8, and the coolant will flow under the drive of the water pump 8. At this time, the coolant in the rear water tank 3 will flow into the fixed pipe 5. Since the cooling pipe 4 is located inside the fixed pipe 5, the coolant will be located between the fixed pipe 5 and the cooling pipe 4. The flowing coolant will efficiently absorb the heat from the pipe wall of the cooling pipe 4 and conduct the heat to the fixed pipe 5. Then, the heat absorbed by the fixed pipe 5 will be absorbed by the heat dissipation fins 9. Due to the design of the heat dissipation fins 9, the heat dissipation fins 9 can dissipate the heat in the form of convection, thereby achieving the function of efficient cooling of the lubricating oil.

[0054] Next, the cooled lubricating oil will be pushed by the auger 12 to the discharge pipe 6 and discharged from the opening of the discharge pipe 6. At the same time, the coolant will flow through the rear water tank 3 and enter the circulation pipe 7 to complete the circulation. At this time, the coolant will be affected by the high temperature of the lubricating oil and will have a certain temperature. Therefore, when the coolant flows through the circulation pipe 7, it will conduct heat to the circulation pipe 7. Then, the heat on the circulation pipe 7 will be absorbed by the heat dissipation fins 9 and dissipated efficiently, thereby cooling the coolant and ensuring the cooling effect on the lubricating oil in the future.

[0055] When the operator needs to improve the heat dissipation effect of the heat sink 9, the operator starts the power motor 22. The rotating shaft 23 then drives the drive wheel 24 to rotate. The drive wheel 24, in turn, drives the driven wheel 20 to rotate via the transmission belt 25. The driven wheel 20 then drives the short shaft 19 to rotate around its connection point with the fixed block 18. Since the outer surface of the transmission belt 25 is movably connected to the outer surface of the rotating wheel 26, the transmission belt 25 simultaneously drives the rotating wheel 26 to rotate. The rotating wheel 26 then drives the vertical shaft 27 to rotate around its connection point with the fixed block 18. At the same time, the fan blades 28 will rotate under the drive of the vertical shaft 27. Due to the design of the fan blades 28, when the fan blades 28 rotate, they will blow air onto the heat dissipation fins 9 to increase the airflow speed inside the heat dissipation fins 9, thereby enhancing the heat exchange efficiency of the heat dissipation fins 9 and thus realizing the function of enhancing the heat dissipation effect of the heat dissipation fins 9. Due to the design of the tension wheel 29, the contact area between the transmission belt 25 and the driven wheel 20, the drive wheel 24 and the rotating wheel 26 can be increased, thereby increasing the friction between the transmission belt 25 and the driven wheel 20, the drive wheel 24 and the rotating wheel 26, thereby ensuring the stability of the transmission of the transmission belt 25.
