[0002] Currently, an air compressor station refers to a compressed air station, which consists of an air compressor, gas storage tanks (divided into primary and secondary gas storage tanks), air treatment and purification equipment, and a refrigerated dryer. Among them, the compressed air circulation filtration system is one of the most important equipment in the air treatment and purification equipment, mainly used for filtering impurities in the air entering the compressor.

[0003] The existing compressed air circulation filtration system usually includes an air filter. A filter plate is arranged inside the air filter. The impurities in the air are filtered through the filter plate, and the impurities are intercepted on the filter plate. The filtered gas enters the air compressor for processing, and the processed gas is transported out for subsequent treatment.

[0004] In the above related technology, during the use of the filter plate, impurities will accumulate on the filter plate. As the use time increases, the filter plate will be blocked, resulting in the defect of low air filtration efficiency. Summary of the Invention

The cleaning device includes a scraper that abuts against the filter plate and is used for cleaning the impurities on the filter plate, and a driving mechanism that is arranged on the air filter and is used for driving the scraper to move. The scraper is slidably matched with the air filter.

[0008] By adopting the above technical solutions, through the setting of the cleaning device, starting the driving mechanism can drive the scraper to slide along the filter plate, and scrape off the impurities intercepted after air filtration on the filter plate, realizing convenient cleaning of the filter plate, reducing the phenomenon of blockage of the filter plate, and thus improving the air filtration efficiency.

[0009] Optionally, the driving mechanism includes a screw rod that is rotatably matched with the air filter and threadedly matched with the scraper, and a driving component that is arranged on the air filter and is used for driving the screw rod to rotate.

[0036] Refer to Figure 1 and Figure 2 , in order to be able to clean the impurities on the filter plate 2, a cleaning device 3 is arranged on the air filter 1. The cleaning device 3 includes a scraper 31 abutted against the filter plate 2 and a driving mechanism 32 arranged on the air filter 1. The scraper 31 is slidably fitted on the air filter 1. The scraper 31 is arranged along the width direction of the filter plate 2, and a tip is arranged at the bottom end of the scraper 31 for cleaning the impurities on the filter plate 2.

[0037] Refer to Figure 1 and Figure 2 , the driving mechanism 32 is used to drive the scraper 31 to move. The driving mechanism 32 includes a screw rod 321 rotatably fitted on the air filter 1 and threadedly fitted on the scraper 31 and a driving assembly 322 arranged on the air filter 1. The screw rod 321 is arranged along the length direction of the filter plate 2, and the air filter 1 rotatably supports the screw rod 321.

[0038] Refer to Figure 1 and Figure 2 , the driving assembly 322 is used to drive the screw rod 321 to rotate. The driving assembly 322 includes a driving member 323 fixedly installed on the air filter 1, a worm 324 fixedly installed on the output end of the driving member 323, and a worm gear 325 meshed with the worm 324 and used to drive the screw rod 321 to rotate. The driving member 323 can directly adopt a motor. A plate for rotatably supporting the worm 324 is fixedly arranged on the air filter 1. The worm gear 325 is fixedly connected to the screw rod 321.

[0039] Refer to Figure 1 and Figure 2, when it is necessary to clean the impurities on the filter plate 2, the driving member 323 is started to drive the worm 324, the worm gear 325 and the screw 321 to rotate in sequence, driving the scraper 31 to slide along the upper surface of the filter plate 2 and scraping off the impurities on the upper surface of the filter plate 2. A collection box 10 is fixedly arranged on one side of the air filter 1 away from the driving assembly 322. The collection box 10 is a hollow rectangular box. The middle cavity of the collection box 10 is divided into two storage spaces arranged at intervals. Two rectangular grooves are arranged at intervals along the height direction of the air filter 1 on the side of the collection box 10 close to the filter plate 2. Each storage space is correspondingly arranged with each rectangular groove. When the scraper 31 scrapes off the impurities on the filter plate 2, the impurities can be pushed into the lower storage space for storage. A door (not shown in the figure) that can be opened is arranged at the lower storage space of the air filter 1, which is convenient for cleaning the impurities in the lower storage space.

The cleaning mechanism 6 includes a conveying pipeline 61 fixedly arranged at the air outlet of the air compressor 4 and used to convey compressed air, and a connecting pipeline 62 fixedly arranged on the conveying pipeline 61. The conveying pipeline 61 is in a "Z" - shaped structure, and the end of the conveying pipeline 61 away from the air compressor 4 is connected to the subsequent air processing equipment. The conveying pipeline 61 is communicated with the air delivery pipeline 5 through the connecting pipeline 62, and a one - way valve 7 is fixedly arranged on the connecting pipeline 62. The air processed by the air compressor 4 can be conveyed through the conveying pipeline 61. When it is necessary to blow the air filter 1 in the reverse direction, the one - way valve 7 is opened, and the processed air can enter the air filter 1 through the conveying pipeline 61 and the connecting pipeline 62, blowing the air filter 1 in the reverse direction, so that the impurities in the filter holes are blown out of the filter holes, then the scraper 31 is used for scraping, and at the same time, the filter plate 2 can be dried, reducing the occurrence of the phenomenon that the water doped in the air accumulates on the filter plate 2.

[0041] Refer to Figure 1 and Figure 3, in order to intercept the water doped in the air and reduce the occurrence of the phenomenon that the water in the air still needs to be cleaned by a separately set device later, an adsorption device 8 is provided on the air filter 1. The adsorption device 8 includes a support plate 81 fixedly arranged on the air filter 1 and an elastic adsorption plate 82 fixedly installed on the support plate 81 and used for adsorbing the water in the air.

A plurality of relief holes 811 with a diameter larger than the diameter of the filter holes are formed in the support plate 81. The support plate 81 is arranged obliquely downward in the direction close to the collection box 10. The elastic adsorption plate 82 can be made of an elastic sponge plate. The water in the air is adsorbed by the elastic adsorption plate 82. At the same time, larger impurities in the air can be intercepted by the elastic adsorption plate 82, and smaller impurities can reach the filter plate 2 after passing through the elastic adsorption plate 82 and the support plate 81.

[0042] Referring to Figure 1 and Figure 2 , an extrusion device 9 is provided on the scraping plate 31. The extrusion device 9 includes an extrusion frame 91 slidably fitted on the support plate 81 and used for extruding the elastic adsorption plate 82 and a connection component 92 provided on the scraping plate 31 for connecting the scraping plate 31 and the extrusion frame 91. The extrusion frame 91 is in a "return" shape structure. The top of the extrusion frame 91 presses on the elastic adsorption plate 82, and the bottom of the extrusion frame 91 abuts against the lower surface of the support plate 81.

[0043] Referring to Figure 1 and Figure 2 , the connection component 92 includes a plurality of support sleeves 921 fixedly arranged on the upper surface of the scraping plate 31 and the lower surface of the extrusion frame 91 and springs 922. Two rows of support sleeves 921 in the height direction of the air filter 1 are symmetrically arranged. The springs 922 are arranged in the height direction of the air filter 1, and the two ends of the springs 922 are respectively fixedly connected to the two support sleeves 921 in the height direction of the air filter 1.

[0044] Referring to Figure 1 and Figure 2, when the scraper 31 slides towards the collection box 10, it can drive the support sleeve 921, the spring 922 and the extrusion frame 91 to slide simultaneously. The extrusion frame 91 slides along the support plate 81 towards the collection box 10 to squeeze the water on the elastic adsorption plate 82, and the squeezed water can enter the storage space above the collection box 10 for storage. A pipeline (not shown in the figure) for conveying the water in the upper storage space is connected to the storage space above the collection box 10, and a control valve is provided on the pipeline. Open the control valve to discharge the water. When the extrusion frame 91 slides towards the collection box 10, the spring 922 can be squeezed, causing the spring 922 to contract. When the extrusion frame 91 slides away from the collection box 10, the spring 922 releases the elastic restoring force to drive the extrusion frame 91 to reset.

[0045] Referring to Figure 1 and Figure 3 , in order to improve the cleaning efficiency of the filter plate 2, a cleaning device 11 is provided on the collection box 10. The cleaning device 11 includes a cleaning pipe 111 for cleaning the filter plate 2 and a water conveying component 112 for conveying the water in the collection box 10 into the cleaning pipe 111.

The water conveying component 112 includes a water conveying pipe 113 communicated with the storage space above the collection box 10 and a water pump 114 fixedly installed on the collection box 10. One end of the water pump 114 is fixedly connected to the water conveying pipe 113, and the other end is fixedly connected to the cleaning pipe 111.

[0046] Referring to Figure 1 and Figure 3 , when the filter plate 2 needs to be cleaned, start the water pump 114, extract the water in the collection box 10 through the water conveying pipe 113, and spray it out through the cleaning pipe 111 and the spray nozzles to clean the filter plate 2. After the cleaning is completed, the filter plate 2 can be dried by the cleaning mechanism 6.

[0047] The implementation principle of the compressed air circulation filtration system of the air compressor station in the embodiment of the present application is as follows: when the air needs to be filtered, the air first enters the air filter 1, and the elastic adsorption plate 82 adsorbs and preliminarily filters the water in the air. Then the air reaches the filter plate 2, and the filter plate 2 intercepts the impurities in the air. The filtered air enters the air compressor 4 for processing and is then conveyed out;

[0048] When it is necessary to clean the impurities at the filter plate 2 and the water on the elastic adsorption plate 82, start the cleaning device 3. Scrape the impurities on the filter plate 2 through the scraper 31, squeeze the water on the elastic adsorption plate 82 through the extrusion frame 91. The impurities and water both enter the collection box 10. Start the cleaning device 11 to clean the filter plate 2. At the same time, blow air to the air filter 1 through the cleaning mechanism 6 to blow out the impurities in the filter holes, and at the same time dry the filter plate 2.
