[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and machinery to reduce friction and protect the machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. High temperatures accelerate the oxidation process of lubricating oil, producing acidic substances, precipitates, and sludge, which reduces the service life and performance of the lubricating oil. Cooling can lower the temperature of the lubricating oil, slow down the oxidation reaction, and extend the storage and service life of the lubricating oil.

[0003] A search revealed a cooling device for lubricating oil production, according to publication number CN216898044U. The device includes a cooling tank with multiple support legs. The cooling tank contains multiple cooling components, each comprising multiple first and second cooling plates. Each first and second cooling plate has multiple oil drain holes and an internal cavity. A first and second pump body are fixed to the cooling tank. Each first and second cooling plate has an inlet pipe and an outlet pipe communicating with the cavity. The inlet pipes are connected to the first pump body, and the outlet pipes are connected to the second pump body. The cooling tank has an outlet and an inlet communicating with it. Both the first and second pump bodies are connected to a water supply unit. This device improves the cooling effect and efficiency of the lubricating oil, thereby increasing production efficiency and enabling continuous production, further enhancing overall efficiency.

[0004] Based on the aforementioned patent, the existing cooling devices mentioned in the background art have poor cooling effect and long cooling time, resulting in low production efficiency. In order to address this technical problem, this application proposes a multi-stage cooling device for lubricating oil production. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-stage cooling device for lubricating oil production. Through multi-stage cooling, the lubricating fluid can be cooled quickly, improving cooling efficiency. Additionally, a dustproof screen is installed to prevent the air pump from blowing dust into the lubricating fluid, and the dustproof screen can be easily removed for cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage cooling device for lubricating oil production, comprising a base, a support frame fixedly connected to the top of the base, a feed hopper fixedly connected to the left side of the top of the support frame, a connecting pipe fixedly connected to the bottom of the feed hopper, a U-shaped pipe fixedly connected to the other end of the connecting pipe, a housing fixedly connected to the other end of the U-shaped pipe, a material conveying assembly provided on the bottom of the housing, an air pump fixedly connected to the right side of the top of the support frame, an air inlet pipe fixedly connected to the right end of the air pump, the air inlet pipe being connected to a mounting frame via a snap-fit ​​assembly, a dustproof net fixedly connected to the inner wall of the mounting frame, and an air outlet pipe fixedly connected to the bottom of the air pump.

[0007] Furthermore, the material conveying assembly includes a motor fixedly connected to the top of the support frame, a rotating shaft fixedly connected to the drive end of the motor, and a propeller blade fixedly connected to the outer wall of the rotating shaft.

[0008] Furthermore, a sleeve is fixedly connected to the bottom end of the inner wall of the housing, and the sleeve is fitted over the outside of the propeller blade.

[0009] Furthermore, a slot is provided on the bottom side of the outer wall of the sleeve, and a guide plate is fixedly connected to the top side of the outer wall of the sleeve.

[0012] Furthermore, a fan unit is fixedly connected to the inner wall of the top of the support frame, and the fan unit is located above the U-shaped tube.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, lubricating oil is added from the feed hopper and passes through the U-shaped tube. Then, the fan unit blows air into the U-shaped tube to remove its heat.

[0022] 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.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a multi-stage cooling device for lubricating oil production, comprising a base 1, a support frame 2 fixedly connected to the top of the base 1, a feed hopper 4 fixedly connected to the left side of the top of the support frame 2, a connecting pipe 5 fixedly connected to the bottom of the feed hopper 4, a U-shaped pipe 6 fixedly connected to the other end of the connecting pipe 5, a housing 7 fixedly connected to the other end of the U-shaped pipe 6, the bottom of the housing 7 fixedly connected to the top of the base 1, a motor 9 fixedly connected to the top of the support frame 2, a rotating shaft 10 fixedly connected to the drive end of the motor 9, a propeller blade 11 fixedly connected to the outer wall of the rotating shaft 10, a sleeve 12 fixedly connected to the bottom of the inner wall of the housing 7, the sleeve 12 being fitted over the propeller blade 11, a slot being opened on the bottom side of the outer wall of the sleeve 12, a guide plate 13 fixedly connected to the top side of the outer wall of the sleeve 12, and a fan unit 3 fixedly connected to the inner wall of the top of the support frame 2, the fan unit 3 being located above the U-shaped pipe 6.

[0024] Specifically, lubricant is added from the feed hopper 4. The lubricant will enter the U-shaped tube 6 through the connecting pipe 5 by gravity. The U-shaped tube 6 is a good heat conductor and can absorb the heat in the lubricant onto the U-shaped tube 6. Then, the fan unit 3 is started. The fan unit 3 consists of multiple fans. The air blown by the fan unit 3 will pass over the surface of the U-shaped tube 6 and carry away the heat from the surface of the U-shaped tube 6. Finally, the lubricant will enter the housing 7. The slot opened on the bottom side of the sleeve 12 allows the propeller blade 11 to carry the lubricant into the air and press it down against the guide plate 13, so that the lubricant forms a dynamic flow, increasing the contact opportunity with the cooling air and further improving the cooling effect.

[0025] Reference Figure 3 and Figure 4 An air pump 14 is fixedly connected to the top right side of the support frame 2. An air inlet pipe 15 is fixedly connected to the right end of the air pump 14. Insert rods 20 are slidably connected to both sides of the inner wall of the mounting frame 17. A locking block 21 is fixedly connected to the opposite end of each insert rod 20. A slot is opened on both sides of the outer wall of the air inlet pipe 15. The locking block 21 fits the shape of the slot. A handle 19 is fixedly connected to the opposite end of each insert rod 20. A spring 8 is fixedly connected to the opposite end of each handle 19. The other end of the spring 8 is fixedly connected to the left and right ends of the mounting frame 17 respectively. A dustproof net 18 is fixedly connected to the inner wall of the mounting frame 17. An air outlet pipe 16 is fixedly connected to the bottom end of the air pump 14.

[0026] Specifically, the dust filter 18 installed on the intake pipe 15 can isolate dust and prevent the air pump 14 from blowing dust into the lubricating fluid. When cleaning the dust filter 18 later, the handles 19 on both sides can be pulled to move the locking block 21 outward through the insert rod 20, so that it is removed from the limit of the intake pipe 15. Then the mounting frame 17 can be removed, and the dust filter 18 on the mounting frame 17 can be cleaned. After cleaning, the handles 19 on both sides can be pulled again, and then the mounting frame 17 can be installed.

[0027] Working principle: First, start the fan unit 3, then add lubricating oil from the feed hopper 4. The lubricating oil will enter the U-shaped tube 6 from the feed hopper 4 through the connecting pipe 5. The U-shaped tube 6 will absorb the heat in the lubricating oil. At the same time, the air blown by the fan unit 3 will pass over the surface of the U-shaped tube 6, carrying away the heat from the surface of the U-shaped tube 6. Then the lubricating oil will enter the housing 7. Start the motor 9, which drives the rotating shaft 10 to rotate. The rotating shaft 10 drives the propeller blade 11 to rotate, raising the lubricating oil inside the housing 7 into the air, and then falling down along the guide plate 13. At the same time, start the air pump 1. 4. The air pump 14 will draw air from the air inlet pipe 15. The dust screen 18 installed on the air inlet pipe 15 can prevent dust from being drawn in. Then the air will blow the lubricating fluid from the air outlet pipe 16, causing its heat to evaporate and accelerating the cooling speed of the lubricating fluid. When cleaning the dust on the dust screen 18 later, the handles 19 on both sides can be pulled to move the insert rod 20. The insert rod 20 will move the locking block 21 outward, so that it is released from the limit of the air inlet pipe 15. Then the mounting frame 17 can be removed, and the dust screen 18 on the mounting frame 17 can be cleaned.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
