[0021] like Figs. 1-3 As shown, a pre-filter mechanism for a compressed air dryer includes a housing 1, with an inlet pipe 2 and an outlet pipe 3 fixedly connected to both ends of the housing. A dust removal filter plate 6 is installed inside the housing. The dust removal filter plate is made of polypropylene fiber, which effectively removes dust, sand, and other impurities from the air. A dust outlet 4 is located on the side of the dust removal filter plate near the inlet pipe, at the bottom of the housing. During filtration, dust is blocked by the dust removal filter plate and falls out of the dust outlet under gravity. A dust collection box is located below the dust outlet, where dust is collected. Adjustable mounting seats are symmetrically arranged on the upper and lower sides of the housing. The adjustable mounting bases are located inside the housing near the outlet pipe. A filter element 8 is installed between the two adjustable mounting bases. The filter elements in this device are made of materials such as activated carbon and electrostatic fibers. Filter elements made of different materials will have different thicknesses. The two adjustable mounting bases can accommodate filter elements of different thicknesses. The two adjustable mounting bases are symmetrically arranged on the upper and lower sides of the housing. Each adjustable mounting base includes a fixed plate 701 fixedly connected to the housing. Both ends of the fixed plate are provided with sliding grooves 7011. Insertion plates 703 are slidably connected to the two sliding grooves respectively. A movable plate 702 is fixedly connected to one end of each of the two insertion plates. Two plug-in plates are fixedly connected to the side of the same movable plate. The plug-in plates are perpendicular to the movable plate, and the movable plate and the fixed plate are parallel and of the same height. The movable plate and the fixed plate have the same width. Each plug-in plate has a slot 7031, and each slot has a fixing screw hole 706 below it. The fixing screw hole is located on the housing, on the side of the housing away from the intake pipe. A fixing bolt 705 is threaded into the fixing screw hole. The fixing bolt passes through the matching slot to fix the plug-in plate to the housing. Each fixing bolt passes through the slot and the housing in sequence. The housing has an external... Each fixing bolt has a matching fixing nut, and each fixing bolt is fitted with a corresponding fixing nut. Each fixing bolt is fitted with a rubber gasket 704 inside the housing. Each rubber gasket is fitted onto the corresponding fixing bolt, and the rubber gasket can seal the fixing bolt hole to ensure the airtightness of the housing. A sealing plate (not shown in the figure) is provided on one side of the powder collection box of the housing. The sealing plate is installed on the housing by multiple mounting bolts. A sealing gasket (not shown in the figure) is provided between the sealing plate and the housing. When the filter element needs to be replaced, the sealing plate must be removed so that the filter element can be replaced.

[0022] A slide 5 is welded onto the housing to support the dust collection box. The dust collection box is slidably connected to the slide 5, facilitating timely cleaning by operators. An electric push rod 9 is located on the side of the housing near the air inlet. The electric push rod can reciprocate. A cleaning brush 10 is fixedly connected to the lower end of the electric push rod. The cleaning brush abuts against the surface of the dust collector filter plate. A drive motor is located at the upper end of the electric push rod to drive its reciprocating motion. When filtration is not required, the drive motor is turned on, and the electric push rod moves up and down, driving the cleaning brush to clean the surface of the dust collector filter plate. During filtration, some impurities will adhere to the dust collector filter plate. The cleaning brush can remove these impurities, improving the service life of the dust collector filter plate. The housing has U-shaped mounting slots, symmetrically located on the upper and lower sides. The dust collector filter plate is placed in the U-shaped mounting slots, which are located on the side of the housing near the air inlet pipe. The thickness of the dust collector filter plate is uniform, so a fixed-size U-shaped mounting slot can be used.

[0023] Working principle

[0024] Compressed air enters through the inlet pipe and then passes through the dust collector filter plate. Dust and other impurities in the compressed air are filtered by the filter plate. Some impurities fall into the dust collection box from the dust outlet under gravity, while others adhere to the filter plate. The compressed air then passes through the filter element for further filtration, removing fine particles, oil, and other contaminants. The filter element can be replaced according to different production needs. Different filter elements have different thicknesses. When the filter element needs to be replaced, remove the outer shell on one side of the housing and tighten the four fixing nuts on the adjustable mounting bases at both ends to move the two movable plates at the top and bottom. Each moving plate moves two fixedly connected insertion plates on it. After moving, the old filter element is removed, and the filter element to be replaced is inserted between the fixed plate and the moving plate at the top and bottom of the housing. The two moving plates are moved to clamp the filter element. After clamping, the four fixing nuts are tightened to fix the position of the two moving plates, thus fixing the filter element. When the filtration structure does not need to perform filtration work, the drive motor is started. The drive motor drives the electric push rod to perform a back-and-forth extension and retraction movement. The electric push rod drives the cleaning brush to clean the surface of the dust collector filter plate, thereby cleaning the surface of the dust collector filter plate, improving the service life of the dust collector filter plate, and improving the filtration quality of the dust collector filter plate.
