[0004] During the use of the above device, it is difficult to clean the dust particles that enter the air compressor. The dust will move between the components with the flow of gas, causing the dust to wear the screw and the star wheel, affecting their meshing accuracy and shortening their service life. In the long run, it may even cause component damage, requiring the replacement of the entire machine head, increasing maintenance costs. Therefore, a single-screw air compressor with an air replenishment function is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a single-screw air compressor with an air supply function in view of the deficiencies in the above-mentioned prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a single-screw air compressor with air replenishment function, comprising a tank body, the top of the tank body is fixedly connected to a chassis, the inner wall of the tank body is provided with a filter device, the inner wall of the chassis is provided with a heat dissipation device, and the inner wall of the chassis is provided with an air intake device; the filter device comprises a motor, a reciprocating screw, a fixed plate 1, a hinged rod, a filter plate, a push plate 1, a fixed plate 2, a detector, a roller 1, and a collection box, the motor is fixedly connected to the left side of the tank body, the reciprocating screw is fixedly connected to the output end of the motor, the filter plate is movably connected to the circumferential surface of the reciprocating screw, the fixed plate 1 is fixedly connected to the left side of the filter plate, the hinged rod is hinged to the inner wall of the fixed plate 1 through a connecting rod, the push plate 1 is fixedly connected to the left side of the hinged rod, the roller 1 is hinged to the inner wall of the hinged rod through a connecting rod, and the collection box is fixedly connected On the inner wall of the tank body, the fixed plate 2 is fixedly connected to the top of the tank body, and the detector is fixedly installed on the top of the fixed plate 2.

When it is detected that the remaining air in the air compressor is insufficient, air is replenished to ensure that the output air pressure is always maintained within the working pressure range required by the equipment. If the air is not replenished in time, the air pressure will gradually decrease with the consumption of air, which may cause the pneumatic equipment to fail to work normally and affect production efficiency. The circumferential surface of the push plate 1 contacts the inner wall of the tank body, and the circumferential surface of the roller 1 contacts the inner wall of the tank body. The circumferential surface of the reciprocating screw is rotatably connected to the inner wall of the tank body.

When the device is started, the detector detects that the air inside the air compressor is insufficient and then replenishes air to maintain a stable working pressure. When it is detected that the remaining air in the air compressor is insufficient, air is replenished to ensure that the output air pressure is always maintained within the working pressure range required by the equipment. If the air is not replenished in time, the air pressure will gradually decrease as the air is consumed, which may cause the pneumatic equipment to fail to work normally and affect production efficiency.

The trapezoidal plate moves upward, thereby ensuring that air can evenly enter the interior of the air compressor so that the screw can compress the air under a stable working state. The screw air compressor compresses the air through a pair of mutually meshing screws. The uniform air intake allows the screw to operate under a suitable load, avoiding large fluctuations in the output pressure due to sudden changes in the air intake amount, so that the desiccant inside the drying box is moved by rotating the fan-shaped plate 2.

The desiccant inside the drying box 511 can prevent many metal parts inside the air compressor from being affected by humid air for a long time, and the humid air will cause these metal parts to rust and corrode.

[0020] Working principle: When the device is started, the L-shaped plate 501 moves, and the L-shaped plate 501 moves and contacts the slide plate 502, so that the slide plate 502 moves forward and backward, and the slide plate 502 moves forward and backward to drive the guide plate 504 to move, and the guide plate 504 moves and contacts the trapezoidal plate 505, so that the trapezoidal plate 505 moves upward through the extrusion of the inclined surface, and the trapezoidal plate 505 moves upward, thereby ensuring that air can evenly enter the air compressor so that the screw can compress the air in a stable working state. The screw air compressor compresses the air through a pair of mutually meshing screws, and the air intake is even. The screw can be operated under a suitable load to avoid large fluctuations in output pressure due to sudden changes in intake volume. The push plate 2 408 moves to drive the roller 508 to rotate through friction. The rotation of the roller 508 drives the rotating rod 3 509 to rotate. The rotation of the rotating rod 3 509 drives the fan plate 2 510 to rotate, so that the desiccant inside the drying box 511 is moved by the rotation of the fan plate 2 510. The desiccant inside the drying box 511 can prevent many metal parts inside the air compressor from being affected by humid air for a long time. The humid air will cause these metal parts to rust and corrode.
