Description

TECHNICAL FIELD

[0001] The utility model relates to air compressor technology field, concretely is a filterable screw air compressor. BACKGROUND

[0002] With the development of industrial automation and manufacturing technology, screw air compressors have been widely used in various industrial fields. Screw air compressors have become important equipment in many industrial production processes due to their high efficiency and stability, especially in applications requiring high pressure gas, such as pneumatic tools, pharmaceuticals, food processing, electronics manufacturing, etc. However, the gas produced during the operation of the air compressor often contains impurities, oil mist and moisture, which not only affect the quality of the gas, but also may damage the service life and efficiency of the subsequent equipment.

[0003] Traditional screw air compressors mainly rely on single-stage supercharging systems, and the gas is directly discharged after compression, making it difficult to achieve efficient filtration and cleaning. To solve this problem, many existing technologies use multi-stage filtration systems that use multiple filters to remove impurities and moisture from the gas. These systems usually include multi-stage filtration devices such as coarse filtration, fine filtration and adsorption filtration. However, the existing multi-stage filtration system still has the following shortcomings:

[0004] Unstable filtration effect: The filtration effect of many existing systems is greatly affected by airflow fluctuations and filter aging, resulting in the cleanliness of the gas being unable to maintain at an ideal level.

[0005] Complex structure, high maintenance cost: Traditional multi-stage filtration devices usually use multiple filters and complex piping systems, with a short maintenance cycle, requiring frequent replacement of filters and cleaning of pipes, increasing the maintenance cost of the equipment.

[0006] Pressure and filtration mismatch: In traditional designs, pressure and filtration are often performed independently, with poor coordination between the gas pressure and purification processes, resulting in low pressure efficiency and unsatisfactory filtration effect.

[0007] Therefore, the existing problems are studied and improved, and a filterable screw air compressor is provided to solve the existing problems, aiming to solve the problems and improve the practical value through the technology. SUMMARY

[0008] The utility model aims to solve the technical problems existing in the prior art or related technology.

[0010] The technical scheme of the utility model includes a shell, a pressure filtration cabin, a two-stage pressurizing assembly and multiple matching components, and the main features are as follows:

[0011] The shell is provided with an air inlet guide for guiding external airflow into the air compressor. The surface of the shell is provided with an air inlet guide, which is connected with the pressure filtration cabin through a cover and an air inlet, to ensure smooth airflow.

[0012] The pressure filtration cabin is the core component of the air compressor, mainly used for preliminary supercharging and filtering of gas. One side of the pressure filtration cabin is provided with an air outlet port for gas output. The pressure filtration cabin is internally provided with a filter ring group and a two-stage filter box for secondary filtering of airflow, removing impurities and improving the cleanliness of gas. The surface of the cover is provided with an air inlet for guiding the airflow after preliminary supercharging into the pressure filtration cabin for further processing.

[0013] The two-stage pressurizing assembly includes a runner and a sliding vane, which provides two-stage pressurizing function through eccentric rotation. The center of the outer periphery of the runner is offset from the axis of the shaft, driving the sliding vane to slide tangentially and increasing the compression ratio of the airflow. The outer periphery of the sliding vane is sealed and abuts against the surface of the pressure filtration cabin, the cover and the filter ring group, to ensure that the gas does not leak during the entire compression and filtration process.

[0014] The filter ring group is made of metal material and is provided with an air inlet filter port and an air outlet filter port on the inner side, which performs secondary filtering of airflow through annular arrangement. The air inlet filter port is used to filter the gas entering the pressure filtration cabin, and the air outlet filter port discharges the treated gas to the two-stage filter box. This structure ensures that the gas can be further purified after multiple filtering.

[0015] The two-stage filter box is internally provided with a porous filter block for further adsorption and filtration of harmful impurities to ensure the cleanliness of the airflow. After filtering by the two-stage filter box, the quality of the gas is significantly improved, which is suitable for high-precision equipment or application scenarios requiring high air quality.

[0016] The filter ring group and the two-stage filter box of the air compressor are both made of metal material components, ensuring their durability and structural stability. The inner side of the filter ring group is smooth and glossy, reducing the resistance of airflow and improving the efficiency of gas flow.

[0017] Through the above design, the filterable screw air compressor of the utility model can perform multiple filtering and purification of gas while supercharging, with the following significant advantages:

DETAILED DESCRIPTION

[0029] To make the purpose, technical scheme and advantages of the utility model clearer and more explicit, the utility model will be further described in detail below in combination with specific embodiments and with reference to the drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following is in conjunction with the appendix Figures 1-5 This invention describes a filterable screw air compressor provided by some embodiments of the present invention.

[0032] This embodiment provides a filterable screw air compressor, mainly used for multi-stage pressurization and gas filtration, suitable for industrial environments with high air quality requirements. It mainly includes a housing 100, a filter chamber 200, a two-stage pressurization assembly 300, and matching components. The basic working process of the air compressor is as follows: first, primary pressurization is performed by introducing air through the inlet 110; then, secondary pressurization is performed through the two-stage pressurization assembly 300; finally, the gas is purified through multi-stage filtration to ensure gas cleanliness.

[0033] Housing 100: This component serves as the outer casing of the air compressor, providing space for the various internal components. An air inlet 110 is located inside the housing 100, through which air enters the air compressor. At one end of the housing, a pressure filter chamber 200 is installed, which contains multiple components of the pressurization and filtration system.

[0034] Filter press chamber 200: The filter press chamber 200 is the core part of the air compressor, responsible for pressurizing and initially filtering the gas. It has an external outlet port 210 through which air is discharged. Air first enters the filter press chamber 200 through the inlet port 202 and undergoes primary pressurization. Next, the air flows through the inlet filter port 221, passes through the filter ring assembly 220, and then enters the secondary filter box 230 for further filtration to remove impurities and particulate matter.

[0035] Secondary pressurization assembly 300: This assembly includes a rotor 310 and a vane 320, responsible for providing secondary pressurization. The outer circumference of the rotor 310 is offset from the axis of the shaft 120, causing the vane 320 to slide tangentially, pressurizing the air through eccentric motion. The outer circumference of the vane 320 slides in sealed contact with the surfaces of the filter chamber 200, the cover 201, and the filter ring assembly 220, ensuring airtightness and efficient pressurization.

[0036] Filter ring assembly 220: The filter ring assembly 220 is double-ringed and made of metal. It has an air inlet 221 on the inner side and an exhaust 222 on the outer side. Through its ring arrangement, the filter ring assembly 220 not only filters the gas but also connects to the secondary filter box 230 to further ensure that the gas reaches a high level of cleanliness after multi-stage treatment.

[0037] Secondary filter box 230: The secondary filter box 230 contains porous filter blocks 231 for further adsorption of harmful substances, such as fine particles, oil mist, and other impurities, ensuring the cleanliness of the discharged gas. The gas treated by the secondary filter box 230 is discharged through the outlet port 210.

[0038] The working principle and use process of the utility model:

[0039] In the shell 100, the external airflow enters the filter cabin 200 through the air inlet guide 110, first through the air inlet 202 to carry out the first stage pressurization.

[0040] After the airflow passes through the eccentric rotation of the runner 310 and the sliding sheet 320, it is subjected to secondary pressurization. After the secondary pressurization, the airflow enters the filter ring group 220 through the air inlet filter 221 to carry out preliminary filtration.

[0041] The airflow treated by the filter ring group 220 enters the secondary filter box 230, and is subjected to adsorption and filtration by the porous filter block 231, further removes harmful impurities, and is finally guided out through the air outlet port 210, ensuring the high cleanliness of the gas.

[0042] In this process, the secondary pressurization assembly 300 effectively provides the pressurization and purification functions of the airflow through its eccentric rotation and sealing effect.
