Description

Technical Field

[0001] The utility model belongs to the technical field of compressor filter devices, and in particular relates to an oil filter air release buffer device. Background Art

[0002] The compressor oil filter is a component used for filtering. It uses a filter screen or a filter element to effectively filter out tiny particles and dirt, ensure the quality and stability of the oil, and extend the service life of the compressor. When the compressor is running, the oil will flow in the engine to lubricate and cool various mechanical parts. When there are impurities, particles and dirt in the oil, it will have a negative impact on the operation of the compressor. The compressor oil filter can prevent these impurities and particles from entering the compressor system, keeping the oil clean and pure.

[0003] The prior art has the following disadvantages when using oil filters:

[0004] 1. When the oil filter pressure difference is higher than 100kpa, the oil filter needs to be switched to reduce the oil pressure difference and increase the lubricating oil pressure; when replacing the oil filter screen, there is residual pressure inside the filter, and when the valve is opened, oil will be sprayed due to the high oil pressure, which may easily injure maintenance personnel.

[0005] 2. The lubricating oil flowing out when the oil filter is depressurized cannot be recovered, causing ground pollution and material waste. Utility Model Content

[0006] The utility model aims to provide an oil filter air bleed buffer device, which has an oil filter air bleed buffer function and solves the problem in the prior art that when the oil filter screen is replaced, there is residual pressure inside the filter, and when the valve is opened, oil is sprayed due to high oil pressure.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is that the utility model provides an oil filter degassing buffer device, including an oil filter, a filter screen is arranged inside the oil filter, a vent pipe is arranged on the upper part of the oil filter, the vent pipe is connected to a buffer tank, a vent valve is arranged on the vent pipe, a baffle is arranged in the buffer tank, and an exhaust pipe is arranged on the top of the buffer tank.

[0008] Preferably, the buffer tank is made of a Φ57mm seamless pipe with both ends sealed.

[0009] Preferably, a number of the baffles are arranged on the inner wall of the buffer tank in a vertically staggered distribution.

[0010] Preferably, the vent pipe is a Φ20 mm pipe, and the bottom of the vent pipe is connected to the oil filter via a quick connector.

[0011] Preferably, the exhaust pipe is a Φ18 mm pipe, and the top end of the exhaust pipe is bent 180° downward.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model avoids the situation that the oil filter sprays outwards due to high oil pressure when the valve is opened to release the pressure, thus eliminating the potential safety hazard for maintenance personnel, saving lubricating oil costs and reducing waste;

[0014] 2. The utility model has an oil filter degassing buffer function, which solves the problem in the prior art that when the oil filter screen is replaced, there is residual pressure inside the filter, and when the valve is opened, oil is sprayed due to high oil pressure.

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment 1, as Figure 1 As shown, an oil filter degassing buffer device includes an oil filter 1. The oil filter 1 is a compressor oil filter, including two types of fine filtration and coarse filtration. The oil filter 1 is used to filter impurities, particles and dirt in the oil to ensure the cleanliness and purity of the oil. A filter screen 2 is arranged inside the oil filter 1, and the filtering effects of fine filtration and coarse filtration are achieved through different types of filter screens 2.

[0021] A vent pipe 3 is provided at the top of the oil filter 1, and the vent pipe 3 is used to release the residual pressure and gas inside the oil filter 1. The vent pipe 3 is connected to a buffer tank 4, and the buffer tank 4 is used to buffer and divert the gas and lubricating oil discharged from the oil filter 1 to avoid pollution and waste caused by the spraying of lubricating oil. A vent valve 5 is provided on the vent pipe 3, and the vent valve 5 is used to control the opening and closing of the vent pipe 3 to control the release of gas inside the vent tank.

[0022] A baffle plate 6 is provided in the buffer tank 4, which is used to buffer and divert the gas and lubricating oil discharged from the oil filter 1, and can effectively block the sprayed lubricating oil. An exhaust pipe 7 is provided on the top of the buffer tank 4, and the exhaust pipe 7 is used to discharge the gas discharged from the buffer tank 4 through the vent pipe 3.

[0023] The following is a detailed description of the design of the above key components:

[0024] The buffer tank 4 is made of a Φ57mm seamless pipe with both ends sealed. This design has a stable structure and good sealing performance, and can withstand the pressure of internal gas and lubricating oil. The seamless pipe manufacturing can reduce the risk of leakage and facilitate production, installation and maintenance.

[0025] The baffles 6 are arranged on the inner wall of the buffer tank 4 in a vertically staggered distribution, which can effectively divert and block the gas and lubricating oil discharged from the vent pipe 3, reduce the impact of gas impact and injection, protect the safety of operators and the environment, and help balance the internal gas flow and improve the buffer effect.

[0026] The vent pipe 3 is a Φ20mm tube, and the bottom of the vent pipe 3 is connected to the oil filter 1 through a quick connector. This design is convenient for installation and connection, and is conducive to the smooth discharge of gas and lubricating oil. The quick connector facilitates the replacement and maintenance of the vent pipe 3. After pressure relief, the lubricating oil flows back to the oil filter 1 for continued use.

[0027] The exhaust pipe 7 is a Φ18mm tube, and the top of the exhaust pipe 7 is bent 180° downward, which is conducive to discharging the gas and lubricating oil inside the buffer tank 4, while avoiding directly spraying the gas outward. The length of the exhaust pipe 7 is extended by the bending design, which is conducive to reducing gas backflow and ensuring smooth exhaust and safe discharge.
