Description

Technical Field

[0001] The utility model belongs to the technical field of air compressors, in particular to an air filter element of an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. It compresses a large amount of air to a high-pressure state through the three processes of suction, compression, and exhaust, and stores it in a tank. When compressed air is needed, the compressor releases the gas in the tank and transports it to the place where it is needed through a pipeline. Air compressors can transport gas, synthesize and aggregate gas, refrigerate and separate gas, and are therefore mainly used in industrial production, energy industry, construction industry, medical industry, agriculture and gardening, air purification and water treatment, as well as scientific research and testing. When using an air compressor, an air filter element is usually required to filter the air entering the compressor to ensure its normal operation. However, it still has the following disadvantages in actual use:

[0003] The invention patent with publication number CN108916007A discloses an air filter element for an air compressor, wherein an upper cover is installed on the upper end surface of the filter element body, an air inlet is provided in the middle position of the upper end surface of the upper cover, a mounting block is provided in the middle position inside the filter element body, a connecting rod is installed on the annular side surface of the mounting block, the mounting block is connected to the inner wall of the filter element body through the connecting rod, a turntable is installed on the upper end surface of the mounting block, a rotating rod is installed on the upper end surface of the turntable, a spiral blade is installed on the annular side surface of the rotating rod, and a sponge brush is installed on the right end surface of the spiral blade. Although the air filter element drives the air flow through the air compressor to rotate the spiral blade and the sponge brush to clean the inner wall of the filter element body, thereby avoiding the blockage of the filter element and the decrease in air flow rate, it cannot collect dust and other impurities independently, resulting in a large amount of impurities accumulating in the air filter element during actual use, and a large amount of impurities may cause damage to the filter element body with the rapid flow of air;

[0004] Air compressor air filters often only filter solid particles in the air. However, in actual use, especially in harsh environments, such as production workshops in factories, there is often moisture, oil, adhesives, etc. in the air. Ordinary air filters are difficult to filter and separate gas, liquid and solid particles at the same time. Filter devices that can separate gas, liquid and solid particles at the same time are often more complex in structure, larger in size, expensive and inconvenient to use. Utility Model Content

[0005] The purpose of the utility model is to provide an air filter element for an air compressor. By means of a supporting shell, a cyclone separation component and a waste residue box, the utility model solves the problem that although the air filter element of the air compressor can clean the particles attached to the filter element body through the air flow, a large amount of impurities are still retained in the air filter element and move in the air filter element with the high-speed air flow, which may cause damage to the air filter element, and a simple air filter element is difficult to separate water, oil and solid particles at the same time.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is an air filter element for an air compressor, comprising a supporting shell, a cyclone separation component and a waste residue box. A supporting mesh tube is inserted through the outer peripheral surface of the supporting shell, a filter screen is fixedly fixedly connected to the inner wall of the supporting mesh tube, an inner supporting tube is welded and fixedly installed in the supporting shell, a cyclone separation component is fixedly connected to the inner support tube, a waste residue box is attached to the bottom of the supporting shell, a scraper is provided on the top of the waste residue box, and the scraper is attached to the inner wall of the filter screen;

[0008] The filter can be supported by the supporting mesh tube to ensure the stability of the filter when the air filter is in use. The air can be further filtered through the filter to ensure the filtering effect. When the air enters the air filter, the air first enters the cyclone separation component. The liquid and large dust particles in the gas can fall into the waste box through the bottom of the cyclone separation component under the action of centrifugal force for collection, avoiding the impurity particles from being retained in the supporting shell for a long time, and can filter the solid particles and liquid in the air at the same time. The filter element has a simple and compact structure, few parts, low cost, and greatly improves the filtration efficiency, ensuring the normal use of the air compressor. When cleaning the waste residue and the filter, the scraper can be driven to move while removing the waste residue box to further scrape off a small amount of solid particles attached to the inner wall of the filter, and then the waste residue in the waste residue box can be quickly poured out. The cleaning operation is simple and convenient.

[0009] Furthermore, a ventilation hole is formed through the outer circumference of the inner support tube, a guide frame is welded and fixed to the inner wall of the inner support tube, and a supporting base plate is welded and fixed to the bottom of the inner support tube;

[0010] After the air is processed and discharged through the cyclone separation component, it can be guided by the guide frame, so that a large amount of air is discharged through multiple vents and contacts the filter, avoiding a large amount of air directly contacting one side of the filter, thereby extending the service life of the filter.

[0011] Furthermore, an air inlet threaded pipe is welded through the top of the cyclone separation component, the air inlet threaded pipe is connected to the top of the support shell, and the guide frame is attached to the outer peripheral surface of the cyclone separation component;

[0012] After the high-speed airflow enters the inner side of the cyclone separation component, the dust particles and liquid in the air fall to the bottom of the cyclone separation component under the action of centrifugal force. The clean air is discharged from the cyclone separation component and further filtered through the filter to filter out extremely fine solid particles in the air. The filter element has a simple and compact structure, few parts, low cost, and can handle solid and liquid impurities in the air at the same time, greatly improving the filtration efficiency.

[0013] Furthermore, an air outlet pipe is welded through the top of the outer peripheral surface of the cyclone separation component, and the air outlet pipe is located inside the inner support tube. A sewage threaded pipe is welded through the bottom of the cyclone separation component, and the sewage threaded pipe is connected to the top of the support base plate;

[0014] The impurities filtered by the cyclone separation component fall into the waste box through the drain threaded pipe for collection, preventing the impurity particles from being retained in the support shell for a long time and moving with the air flow to cause damage to the air filter element.

[0015] Furthermore, a threaded connecting pipe is welded through the top of the waste box, a support rod is welded and fixed to the top edge of the waste box, the scraper is welded and fixed to the top of the support rod, the threaded connecting pipe is screwed and fixed to the outer circumference of the sewage threaded pipe, and the support rod is inserted between the inner support pipe and the filter screen;

[0016] When cleaning the air filter, the staff only needs to unscrew and remove the waste box. Removing the waste box can drive the scraper to move at the same time. The scraper can scrape off a small amount of solid particles attached to the inner wall of the filter. There is no need to rinse the filter. The waste residue in the waste box can be quickly poured out. The cleaning operation is simple and convenient.

[0017] The utility model has the following beneficial effects:

[0018] The utility model discloses providing cyclone separation assembly and waste residue box, solves the problem that although the air filter element drives the air flow through the air compressor to make the spiral blades and sponge brush rotate to clean the inner wall of the filter element body, avoiding the blockage of the filter element and the decrease of air flow rate, it cannot collect dust and other impurities independently, resulting in a large amount of impurities accumulating in the air filter element during actual use, and a large amount of impurities may cause damage to the filter element body with the rapid flow of air. After the air enters the cyclone separation assembly, the impurities in the air are filtered by the cyclone separation assembly, and the impurities in the air are dropped to the bottom of the cyclone separation assembly, and the impurities fall into the waste residue box under the action of gravity, and are collected, avoiding the impurity particles from being detained in the supporting shell for a long time and moving with the air flow to damage the air filter element. When cleaning the filter element, it is only necessary to screw and remove the waste residue box to drive the synchronous movement of the scraper. The movement of the scraper scrapes off a small amount of solid particles attached to the inner wall of the filter screen, and there is no need to rinse the filter screen, and then the waste residue in the waste residue box is quickly poured out, and the cleaning operation is simple and convenient.

[0019] The utility model solves the problem that the air filter element of the air compressor often only filters the solid particles in the air by setting a supporting shell and a cyclone separation component. However, in actual use, especially in harsh environments, such as production workshops in factories, there is often moisture, oil, adhesives, etc. in the air. Ordinary air filter elements are difficult to filter and separate gas, liquid and solid particles at the same time. The filtering device that can separate gas, liquid and solid particles at the same time is often more complicated in structure, larger in size, expensive and inconvenient to use. When the air enters the air filter element, it first enters the cyclone separation component. The rapid airflow generates centrifugal force in the cyclone separation component, so that the solid particles and liquid in the air fall to the bottom of the cyclone separation component under the action of centrifugal force and are collected in the waste residue box. The air discharged from the cyclone separation component is further filtered through the filter screen to filter out extremely fine particles in the air. The filter element has a simple and compact structure, few parts, low cost, and can handle solid and liquid impurities in the air at the same time, thereby greatly improving the filtration efficiency.

The filtered air is guided by the guide frame 103 and filtered again through the filter 104 to remove extremely fine particles in the air. The clean air enters the air supply system of the air compressor. After the air filter has been used for a period of time, the waste box 3 is unscrewed and removed, while driving the scraper 301 to move, further scraping off a small amount of solid particles attached to the inner wall of the filter 104, and then the waste residue in the waste box 3 is quickly poured out to complete the cleaning of the air filter.

[0031] After the air is processed and discharged through the cyclone separation component 2, it is guided by the guide frame 103, so that a large amount of air is discharged through multiple vents 105 and contacts the filter 104. The air is further filtered by the filter 104 to remove extremely fine particles in the air, so that clean air enters the air supply system of the air compressor.

[0032] Among them Figure 1 、 2 As shown in Figures 4 and 5, an air inlet threaded pipe 201 is welded through the top of the cyclone separation assembly 2, and the air inlet threaded pipe 201 is clamped through the top of the support shell 1.

[0033] The high-speed airflow enters the cyclone separation assembly 2 through the air inlet threaded pipe 201, and forms a strong rotating airflow in the cyclone separation assembly 2, so that the dust particles and liquid in the air fall to the bottom of the cyclone separation assembly 2 under the action of centrifugal force, and are discharged to the waste residue box 3 through the sewage discharge threaded pipe 203 for collection, and the clean air is discharged from the cyclone separation assembly 2 through the air outlet pipe 202.

[0036] The specific working principle of the utility model is as follows: the air filter element is installed in the air intake structure of the air compressor through the air intake threaded pipe 201. When the air compressor is started, the mixed air quickly passes through the air intake threaded pipe 201 and enters the cyclone separation component 2. The high-speed airflow forms a strong rotating airflow in the cyclone separation component 2, so that the dust particles and liquid in the air fall to the bottom of the cyclone separation component 2 under the action of centrifugal force, and are discharged to the waste residue box 3 through the sewage threaded pipe 203 for collection. The clean air is discharged through the air outlet pipe 202 and guided by the guide frame 103. A large amount of air is discharged through multiple vents 105 and contacts the filter 104. The air is further filtered by the filter 104 to remove extremely fine particles in the air, so that clean air enters the air supply system of the air compressor. After the air filter element has been used for a long time, the waste residue box 3 is unscrewed and removed, and the scraper 301 and the support rod 302 are moved at the same time. The scraper 301 slides to scrape off a small amount of solid particles attached to the inner wall of the filter 104, and then the waste residue in the waste residue box 3 is quickly poured out through the threaded connecting pipe 303 to complete the cleaning of the air filter element.
