Description

Technical Field

[0001] The utility model relates to the technical field of oil purifiers, in particular to a circulating cooling energy-saving oil purifier. Background Art

[0002] Oil purifiers, also known as oil filters or filters, are filtration devices that use gravity, centrifugation, pressure, vacuum distillation, mass transfer, and other techniques to remove mechanical impurities, oxidation byproducts, and water from impure oil. Oil purifiers can effectively improve the cleanliness of oil used in machinery, vehicles, and electrical appliances, optimizing performance and extending the life of the equipment. Currently, the most common centrifugal oil purifiers use the centrifugal force of a high-speed rotating drum to separate the residue from the oil, achieving liquid-solid separation. When the drum stops, the purified oil slides out of the drum, achieving filtration. However, the high-speed rotation of the drum can increase the oil temperature within the purifier, affecting filtration stability and the quality of the purified oil.

[0003] To solve the above technical problems, Chinese patent document CN202120249159.2 discloses a centrifugal oil purifier with a cooling function, including a processing cylinder, the top of the processing cylinder is fixedly connected to an oil inlet hood, the bottom of the processing cylinder is installed with a mounting box, the top of the mounting box is fixedly connected to a fixed disk, the connection between the processing cylinder and the fixed disk is clamped with a fixing mechanism, and a cooling mechanism is installed inside the mounting box, and two air inlet hoods are provided in the cooling mechanism, and a centrifugal cylinder is installed in the processing cylinder, and the two air inlet hoods are symmetrically fixedly connected to the two sides of the lower part of the centrifugal cylinder. The above patent uses the air cooler in the cooling mechanism to physically cool the inner cylinder in the oil purifier at any time to avoid the internal temperature of the oil purifier being too high when working. However, the air cooling method for cooling the oil purifier is not effective, the heat exchange efficiency is low, and a separate motor needs to be set up to power it, which consumes a lot of energy and affects the production cost.

[0004] Therefore, it is necessary for those skilled in the art to provide a circulating cooling energy-saving oil purifier to improve the efficiency of heat exchange, ensure the stability of the oil purifier and reduce the production cost. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0022] See also Figure 1 、 Figure 4 The utility model provides a circulating cooling energy-saving oil purifier, including a frame 10, an oil purifier tank body 11 and a water tower 12 installed on the frame 10, a driving motor 13 is provided under the oil purifier tank body 11, and the output shaft of the driving motor 13 passes through the wall of the oil purifier tank body 11 and extends to the interior of the oil purifier tank body 11, so as to provide power for the centrifugal oil filtration of the oil purifier.

[0023] The oil purifier tank body 11 is a centrifugal oil filter commonly seen on the market. The utility model only shows its oil purifier tank body 11 and the drive motor 13. A rotatable drum is also provided in the oil purifier tank body 11. The drive motor 13 is used to drive the drum to rotate. The centrifugal force during the high-speed rotation of the drum is used to separate the slag and the oil to achieve liquid-solid separation. When the drum stops rotating, the clean oil slides out of the drum to achieve the filtering purpose. For the specific structure, please refer to the high-efficiency centrifugal oil purifier disclosed in the Chinese patent document CN207845301U, which will not be described in detail here.

[0024] See also Figure 2 、 Figure 3 、 Figure 5The oil purifier tank body 11 is a cylindrical structure with a hollow interior, and a water injection interlayer 14 is provided in the wall of the oil purifier tank body 11. The water injection interlayer 14 is communicated with the water tower 12, and cooling water is provided in the water injection interlayer 14 and the water tower 12. When in use, the oil purifier tank body 11 is fixed relative to the frame 10, and the drum in the oil purifier tank body 11 rotates at a high speed and discharges the separated oil. At this time, the oil has a higher temperature. At the same time, the oil purifier tank body 11 also generates high temperature due to the high-speed rotation of the internal equipment. The utility model uses the water injection interlayer 14 to cool the oil purifier tank body 11 to ensure the stability of the equipment. At the same time, the water injection interlayer 14 can also maintain the oil temperature of the separated oil to prevent high-temperature deterioration and improve product quality.

[0025] Furthermore, a driving gear 15 is fixedly connected to the output shaft of the drive motor 13, and the driving gear 15 is located between the drive motor 13 and the oil purifier tank 11. The frame 10 is also provided with a reversing gear box 19 and a gearbox 16. A driven gear 18 is fixedly connected to the rotating shaft on one side of the reversing gear box 19, and the driving gear 15 and the driven gear 18 are engaged with each other. The rotating shaft on the other side of the reversing gear box 19 is fixedly connected to the input shaft of the gearbox 16 to realize power transmission; a water pump 17 is provided above the gearbox 16, and the output shaft of the gearbox 16 is fixedly connected to the drive shaft of the water pump 17. A water pipe on one side of the water pump 17 is connected to the water injection interlayer 14, and a water pipe on the other side of the water pump 17 is connected to the water tower 12.

[0026] While the drive motor 13 provides power support for the oil purifier, the driving gear 15 is used to synchronously output part of the power, which is sequentially transmitted to the driven gear 18, the reversing gear box 19, the gearbox 16, and finally input into the water pump 17. The water pump 17 drives the cooling water to flow between the water injection interlayer 14 and the water tower 12. The injection of cooling water is achieved while the power is output, ensuring processing stability, reducing energy loss, and thus reducing production costs. At the same time, the utility model uses the driving gear 15 set on the drive motor 13 to achieve power synchronization, without the need for a separate motor, thus reducing energy consumption. After adjustment by the gearbox 16, the water injection speed of the water pump 17 is proportional to the speed of the drive motor 13. The faster the speed of the drive motor 13, the more obvious the heating of the oil purifier tank 11. Therefore, the water injection speed of the water pump 17 is proportionally synchronized with the speed of the drive motor 13. As the heat generated by the oil purifier tank 11 increases, the water injection speed of the water pump 17 increases, thereby improving the cooling efficiency and ensuring the cooling effect.

[0027] In this embodiment, a return pipe 20 is further provided at the bottom of the water tower 12. One end of the return pipe 20 is connected to the water tower, and the other end of the return pipe 20 is connected to the water injection interlayer 14. A one-way valve (not shown) is provided on the return pipe 20 to ensure that the water in the water tower 12 can flow into the water injection interlayer 14 in one direction. The one-way valve is a common pipeline one-way valve on the market. The return pipe 20 cooperates with the water pump 17 to realize the reciprocating transportation of cooling water between the oil purifier tank 11 and the water tower 12, thereby ensuring the stability of cooling.

[0028] In another embodiment, a pressure pump is provided on the return pipe 20 to ensure that the cooling water in the water tower 12 is quickly passed into the water injection interlayer 14. The pressure pump is a common automatic booster pump on the market.

[0029] In this embodiment, the output shaft of the drive motor 13 passes through the water injection interlayer 14. An isolation layer 21 is provided around the output shaft located in the water injection interlayer 14 to prevent cooling water leakage. A sealing gasket (not shown in the figure) is provided between the output shaft of the drive motor 13 and the oil purifier tank body 11. The sealing gasket is made of rubber to ensure the sealing of the oil purifier tank body 11.

[0030] In this embodiment, the water injection interlayer 14 is distributed on the side and bottom of the oil purifier tank 11. Since the high-speed rotating drum and the filtered oil are located in the lower middle part of the oil purifier tank 11, the utility model provides a water injection interlayer 14 at a location prone to heat, and introduces cooling water inward to improve the cooling efficiency. Compared with the air cooling in the prior art, the water cooling heat exchange efficiency of the utility model is higher, and the heat exchange position is more targeted.

[0031] In this embodiment, the reversing gear box 19 and the transmission case 16 are both detachably connected to the frame 10 using fasteners such as bolts or screws to ensure the stability of the connection.

[0032] The specific operation mode of the present invention is as follows: the driving motor 13 is used to drive the drum in the oil purifier tank 11 to rotate, thereby realizing oil and slag separation. While the driving motor 13 is rotating, the driving gear 15 is used to synchronously output part of the power of the driving motor 13, and the power is sequentially transmitted to the driven gear 18, the reversing gear box 19, the gearbox 16, and finally input into the water pump 17. The water pump 17 is used to drive the cooling water to flow between the water injection interlayer 14 and the water tower 12. The cooling water is injected while the power is output, thereby completing the cooling of the oil purifier tank 11.

[0033] The utility model utilizes the driving gear 15 provided on the drive motor 13 to realize the power synchronization between the drive motor 13 and the water pump 17, so that the water injection speed of the water pump 17 is proportional to the rotation speed of the drive motor 13. As the rotation speed of the drive motor 13 is faster, the heating of the oil purifier tank 11 is more obvious, and at the same time, the water injection speed of the water pump 17 will also become faster with the rotation speed of the drive motor 13, thereby improving the cooling efficiency, thereby maintaining the temperature of the oil purifier tank 11, and ensuring the stability of the work and the quality of the product.
