Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to an oil mist separator with a large oil return ball. Background Technology

[0002] Oil mist separators are key components in industrial equipment and internal combustion engine systems, used to filter impurities in oil mist and recover oil to reduce environmental pollution and improve oil utilization. Traditional oil mist separators typically have a return oil structure designed as a sphere or cavity flush with the filter cartridge. Limited by installation space and outlet location, their oil storage capacity is relatively small. Under frequent start-stop or high-load conditions, insufficient oil storage can easily lead to low oil return efficiency and large oil pressure fluctuations, thus affecting system stability and service life. For example, the filter disclosed in patent CN202021147378.1 has a common filter structure. Because the return oil ball is built-in, the filter can stand upright on a flat surface; however, this built-in design also limits the size of the return oil ball.

[0003] In existing technologies, some improvements increase the oil storage capacity by increasing the volume of the filter cartridge, but this leads to an increase in the overall size of the equipment and makes installation inconvenient. Other solutions optimize the shape of the return oil ball or add an auxiliary oil storage chamber, but these are structurally complex and have high manufacturing costs. In addition, traditional oil mist separators lack installation stability, especially in vibration environments, where they are prone to shifting or tipping, leading to seal failure or oil leakage.

[0004] Therefore, there is an urgent need for a new type of oil mist separator that can significantly increase oil storage capacity, optimize oil reflux efficiency, and has a highly stable installation structure. Utility Model Content

[0005] This invention addresses the problems of existing technologies by providing an oil mist separator with a large oil return ball, which can increase the volume of the oil return ball without increasing the volume of the filter barrel.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an oil mist separator with a large oil return ball, 1. comprising an upper cover, a lower cover, and a filter cylinder; the lower cover includes a first assembly part and an oil return ball, the oil return ball being used to hold filtered oil, the first assembly part being integrally connected to the oil return ball, one end of the filter cylinder being installed in the first assembly part, and the other end of the filter cylinder being installed in the upper cover; the bottom of the oil return ball protrudes from the bottom of the first assembly part, and the bottom of the oil return ball and the bottom of the first assembly part are located on different horizontal planes; a base is installed on the outer periphery of the lower cover, the base being provided with a plurality of support components, the support components being used to stabilize the lower cover on a plane.

[0007] Preferably, the support assembly includes a support rod, an upper limit rod, a lower limit rod, and a tensioning unit.

Detailed Implementation

[0023] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0024] This embodiment provides an oil mist separator with a large oil return ball 5, such as... Figures 1 to 7 The filter includes an upper cover 1, a lower cover 2, and a filter cylinder 3. The lower cover 2 includes a first assembly part 4 and an oil return ball 5, which holds the filtered oil. The first assembly part 4 and the oil return ball 5 are integrally connected. One end of the filter cylinder 3 is installed in the first assembly part 4, and the other end is installed in the upper cover 1. The bottom of the oil return ball 5 protrudes from the bottom of the first assembly part 4, and the bottom of the oil return ball 5 and the bottom of the first assembly part 4 are located on different horizontal planes. A base 6 is installed on the outer periphery of the lower cover 2, and the base 6 is provided with several support components 7, which are used to stabilize the lower cover 2 on a plane. The filter cylinder 3 includes, from the outside to the inside, an outer mesh 15, a first protective cotton layer 16, a filter material assembly 17, a second protective cotton layer 18, a middle mesh 19, a filter cotton layer 20, and an inner mesh 21. The material structure of the filter cylinder 3 is existing technology and will not be described in detail here.

[0025] Specifically, such as Figure 2 As shown, in this embodiment, the oil return ball 5 protrudes downward from the filter cylinder 3, thereby increasing the volume of the oil return ball 5 and thus its capacity. However, with the oil return ball 5 protruding from the filter cylinder 3, an imbalance will occur when the filter cylinder 3 needs to be placed on a flat surface. Therefore, this embodiment adds a support component 7, which can be used to maintain balance when needed.

[0026] like Figures 5 to 7 As shown, the support assembly 7 in this embodiment includes a support rod 8, an upper limit rod 9, a lower limit rod 10, and a tensioning unit. The upper limit rod 9 and the lower limit rod 10 are located on both sides of the base 6. The tensioning unit is installed on the base 6, and both the upper limit rod 9 and the lower limit rod 10 are fixed to the tensioning unit. The support rod 8 is installed on the base 6 and has an upper limit hole 11 and a lower limit hole 12. The upper limit rod 9 is inserted into the upper limit hole 11, and the lower limit rod 10 is inserted into the lower limit hole 12. By pulling the tensioning unit, the upper limit rod 9 is controlled to be inserted into the upper limit hole 11, or the lower limit rod 10 is controlled to be inserted into the lower limit hole 12.

[0027] Specifically, a support component 7 is provided in the base 6 to provide support and balance when needed, such as Figure 6 As shown, by pulling the lower limit rod 10 and the upper limit rod 9 to the right using the tensioning unit, the support rod 8 is unlocked. Then, the support rod 8 is moved downwards, and the tensioning unit is released again, allowing the lower limit rod 10 to insert into the lower limit hole 12 of the support rod 8, thus fixing the support rod 8. This allows the support rod 8 to be supported on the plane, ensuring all support rods 8 are at the same height, thus supporting the filter cartridge 3 on the plane and maintaining its balance. The length of the support rod 8 is set according to the size of the oil return ball 5, ensuring that the support rod 8 can be supported on the plane. Conversely, if the support function of the support rod 8 is not needed, the above actions can be repeated: the support rod 8 is moved upwards, and then the upper limit rod 9 is inserted into the upper limit hole 11 to lock the support rod 8, thus retracting the support rod 8. This does not affect the use of the filter cartridge 3 and allows for flexible control.

[0028] Furthermore, such as Figure 5 As shown, the tensioning unit includes a tensioning block 13 and several springs 14. The two ends of each spring 14 are connected to the tensioning block 13 and the base 6, respectively. The springs 14 keep the tensioning block 13 connected to the base 6. Without external force, the tensioning block 13 is close to the base 6 under the elastic force of the springs 14, ensuring that the upper limit rod 9 or lower limit rod 10 can lock the support rod 8. The structure is simple and easy to operate, and the movement of the support rod 8 can be controlled as needed. The number of support components 7 is at least three sets, evenly distributed on the base 6, forming a stable triangular fixing structure. Of course, setting more support components 7 can also provide a more stable support effect.

[0029] like Figure 1 and Figure 4As shown, the upper cover 1 in this embodiment includes a second assembly part 22 and a sealing part 23. The second assembly part 22 and the sealing part 23 are integrally connected. The second assembly part 22 abuts against the top of the filter cartridge 3. The sealing part 23 is equipped with a sealing gasket 24. After the upper cover 1 is assembled to the filter cartridge 3, by assembling the sealing gasket 24, a higher sealing performance can be maintained after assembling the outer cover and other structures. The structure of the sealing gasket 24 is existing technology, such as... Figure 1 As shown.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
