Description

Technical Field

[0001] This utility model relates to the field of lubricating oil manufacturing, specifically to a cooling device for lubricating oil manufacturing. Background Technology

[0002] Lubricating oil needs to be cooled during production. Centrifugal coolers are commonly used for lubricating oil cooling. However, in oil cooling devices, the oil is only diffused in a direction perpendicular to the axial direction of the shaft due to the rotation and stirring action of the shaft and blades. This causes the oil to form layers inside, which hinders the exchange within the oil. As a result, the temperature reached in different zones of the lubricating oil varies during cooling. Therefore, a cooling device for lubricating oil manufacturing is provided. Utility Model Content

[0003] I. Technical problems to be solved

[0004] The technical problem this invention aims to solve is that centrifugal cooling can cause the lubricating oil to form layers inside, which cannot guarantee the sufficiency, uniformity, and efficiency of the lubricating oil cooling process.

[0005] Technical solution

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a cooling device for lubricating oil manufacturing, including a treatment tank.

[0007] The treatment tank is connected to a support, and the support is connected to a lifting channel. The treatment tank is rotatably connected to a driven shaft within the lifting channel. A drive assembly for driving the driven shaft to rotate is installed on the treatment tank. Multiple impellers are evenly installed on the driven shaft. The rotation of the impellers causes the lubricating oil at the bottom of the treatment tank to move upward through the lifting channel.

[0008] A cooling coil is installed in the interlayer between the inner wall and the lifting channel of the treatment tank, which is located on the inner edge of the treatment tank. The cooling coil extends continuously and covers the outside of the lifting channel. A water pump is installed on the cooling coil, and its two ends pass through the treatment tank to the outside and are connected to the cooling end and the return cooling end of the relevant cooling equipment and container, respectively.

[0009] Furthermore, the top and bottom plates of the treatment tank are respectively connected to an oil supply pipe and an oil discharge pipe, and an oil pump is installed on the oil discharge pipe.

[0010] Furthermore, the drive assembly includes a drive shaft rotatably connected to the bottom of the treatment tank, a motor that drives and cooperates with the drive shaft installed below the treatment tank, a main pulley connected to the drive shaft, a secondary pulley connected to the bottom end of the driven shaft extending to the outside of the treatment tank, and a drive belt installed between the main pulley and the secondary pulley.

[0011] Furthermore, the lifting channel is provided with multiple gaps above and below the impeller to allow lubricating oil to exchange between the lifting channel and the interlayer.

[0012] Furthermore, the treatment tank is made of a material with strong thermal insulation properties, or is equipped with relevant thermal insulation measures, and the cooling coil is located in the spiral pipe section inside the treatment tank and is made of a material with strong thermal conductivity. Beneficial effects

[0013] The advantages of this invention compared to the prior art are as follows: The device first sets a tortuous, spiral, continuously extending cooling coil at the edge of the oil treatment tank for lubricating oil cooling. This structural design greatly increases the area of ​​close contact between the oil and the coolant, improving cooling efficiency. Furthermore, an oil lifting channel with a rotating impeller is set inside the cooling coil, causing the lubricating oil in the tank to continuously circulate inside and outside the lifting channel, repeatedly and orderly appearing in the cooling space, thus achieving a more thorough cooling effect.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a cooling device for lubricating oil manufacturing, combined with the attached... Figure 1-2 The treatment tank 1 is made of a heat-insulating material or equipped with related heat insulation measures to prevent people from being burned after contact. The top and bottom plates of the treatment tank 1 are respectively connected to an oil supply pipe 2 and an oil discharge pipe 3, and an oil pump 4 is installed on the oil discharge pipe 3.

[0022] The disposal tank 1, equipped with relevant protective measures, is the place where the device provides cooling for the lubricating oil in production. The lubricating oil that needs to be cooled is poured into the tank from the oil supply pipe 2. Do not fill the tank completely to prevent affecting the cooling effect or the risk of overheating and expansion.

[0023] The oil pump 4 installed at the bottom of the treatment tank 1 is equivalent to a switch. When the lubricating oil in the tank is repeatedly cooled, it closes the outlet at the bottom of the treatment tank 1. When the treatment is completed and the lubricating oil needs to be drained, it opens and can also help to quickly extract the lubricating oil from the tank.

[0024] Combined with appendix Figure 3-4 The treatment tank 1 is connected to a support 6, and a lifting channel 5 is connected to the support 6. The treatment tank 1 is rotatably connected to a driven shaft 13 within the lifting channel 5. Figure 5 The treatment tank 1 is equipped with a drive assembly for driving the driven shaft 13 to rotate. The drive assembly includes a transmission shaft 8 rotatably connected to the bottom of the treatment tank 1. A motor 9 is installed below the treatment tank 1 and drives the transmission shaft 8. A main pulley 10 is connected to the transmission shaft 8. The bottom end of the driven shaft 13 extends to the outside of the treatment tank 1 and is connected to a secondary pulley 12. A transmission belt 11 is installed between the main pulley 10 and the secondary pulley 12.

[0025] Multiple impellers 14 are evenly installed on the driven shaft 13. The rotation of the impellers 14 causes the lubricating oil at the bottom of the treatment tank 1 to move upward through the lifting channel 5. The lifting channel 5 is provided with multiple gaps 7 above and below the impellers 14 to allow the lubricating oil to exchange between the lifting channel 5 and the interlayer.

[0026] A cooling coil 15 is installed in the interlayer between the inner wall and the lifting channel 5 on the inner edge of the treatment tank 1. The cooling coil 15 is located in the spiral pipe section inside the treatment tank 1 and is made of a material with high thermal conductivity. A water pump 16 is installed on the cooling coil 15 and its two ends pass through the treatment tank 1 to reach the outside and are respectively connected to the cooling end and the return cooling end of the relevant cooling equipment and container.

[0027] Cooling pipes are installed inside the treatment tank 1. By setting them into a continuous, spiral structure, the area of ​​close contact between the internal coolant and the external lubricating oil through the pipe wall is increased in a limited space, thereby improving the cooling efficiency. Ammonia coolant is used as the coolant. Under the action of water pump 16, the coolant is continuously fed into the cooling coil 15.

[0028] The cooling end can be made of relevant ammonia coolant preparation equipment or storage container, which is within the scope of existing technology. Therefore, the selection and operation principle of the cooling end will not be elaborated. By continuously supplying new coolant into the treatment tank 1, the lubricating oil in the tank is fully cooled.

[0029] The lubricating oil drives the impeller 14 to rotate via the driven shaft 13. It is not stationary in the treatment tank 1. Due to the rotation of the impeller 14 in the lifting channel 5, an upward water flow is formed in the lifting channel 5. The water is the lubricating oil. After the lubricating oil at the bottom gathers at the bottom of the support 6, it is transported upward from the bottom of the lifting channel 5. The space they leave is filled by the lubricating oil in the upper part of the jacket. This causes the lubricating oil in the jacket to continuously descend. The lubricating oil that is transported upward will overflow when it encounters the gap 7 or reaches the top of the lifting channel 5 and fall back into the jacket, getting multiple opportunities to contact the cooling coil 15 and be further cooled.

[0030] In a specific implementation of this utility model, the treatment tank 1 in the device is placed in a suitable location in the production site, and its oil supply pipe 2 and oil discharge pipe 3 are sealed and connected to the relevant equipment and containers. The two ends of the cooling coil 15 are also sealed and connected to the cooling port and cooling return port of the relevant coolant supply equipment and containers, respectively.

[0031] The lubricating oil that needs to be cooled is sent into the treatment tank 1 through the oil supply pipe 2. The oil pump 4 at the bottom of the tank is turned off, while the motor 9 continues to run, and the coolant is also continuously delivered to the interlayer space inside the tank.

[0032] In the tank, the oil is stirred and lifted by the rotating impeller 14. A portion of the oil is always transported from the bottom to the top of the lifting channel 5. At the same time, oil is constantly falling down from the top of the jacket. The lubricating oil circulates around the cooling coil 15 and is effectively cooled, achieving a sufficient and rapid cooling effect.

[0033] After the cooling process is complete, turn on the oil pump 4 and drain the oil from the tank through the oil drain pipe 3.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
