Description

Technical Field

[0002] Screw air compressor adopts pre-packaged configuration. Screw air compressor only needs a single power connection and compressed air connection, and has a built-in cooling system, which greatly simplifies the installation work. Screw air compressors consistently provide high-quality compressed air for all walks of life with their advantages such as high performance, high efficiency, maintenance-free and high reliability.

[0003] For example, a screw air compressor disclosed in authorization announcement No. CN219974802U, by providing a heat dissipation mechanism and a cleaning mechanism, can not only drive the fan to accelerate the air flow in the box cavity of the protection box when motor 1 is working, and is beneficial to the heat dissipation of the screw air compressor, but also can be connected through the belts of pulley 1 and pulley 2 to rotate the bidirectional screw rod, thereby driving the moving block to move up and down along the rod body of the bidirectional screw rod, and driving the cleaning plate to reciprocate up and down to clean the right surface of the filter plate, which is beneficial to prevent the air vents of the filter plate from being blocked.

[0004] The above solution is to clean the filter plate by a cleaning plate to avoid clogging of the air holes. However, in actual applications, the cleaning plate will squeeze the dust on the filter plate during movement. Part of the dust is pushed to the bottom of the filter plate by the cleaning plate, and the other part of the dust is pressed into the air holes, causing the air holes to be blocked.

[0023] As 1 to Figure 3 As shown,

[0024] A cleaning device for a screw air compressor includes an air intake box 1, which is placed on the screw air compressor. A filter plate 2 is provided in the air intake box 1, and a plurality of filter holes 3 are equidistantly provided on the filter plate 2. A controller 17 is provided on the air intake box 1. A stepper motor 15, an electric push rod 5 and an infrared sensor 8 are all electrically connected to the controller 17. The stepper motor 15 is electrically connected to the electric push rod 5, and the infrared sensor 8 is electrically connected to the electric push rod 5. The infrared sensor 8 senses a contact on the filter plate 2 and sends a signal to the electric push rod 5 and the stepper motor 15, so that the electric push rod 5 pushes the cleaning plate 4 to clean the filter plate 2.

[0025] A movable assembly is provided in the air intake box 1 corresponding to the filter plate 2. There are two groups of movable assemblies, and the two groups of movable assemblies are symmetrically arranged about the center line of the air intake box 1. A cleaning plate 4 is provided between the two groups of cleaning assemblies.

[0026] The moving assembly includes a ball screw 13, a fixed seat 14 and a stepper motor 15. The stepper motor 15 is placed on the lower inner wall of the air intake box 1. The fixed seat 14 corresponds to the stepper motor 15 placed on the upper inner wall of the air intake box 1. The ball screw 13 is placed between the stepper motor 15 and the fixed seat 14. A slide seat 16 is sleeved on the ball screw 13. The slide seat 16 is connected to the electric push rod 5. The stepper motor 15 drives the ball screw 13 to rotate, thereby driving the slide seat 16 to reciprocate on the ball screw 13, thereby driving the cleaning plate 4 to move and clean the end surface of the filter plate 2.

[0027] The upper end surface and the lower end surface of the inner wall of the air intake box 1 are both provided with placement grooves for placing the fixing seat 14 and the stepping motor 15, and the fixing seat 14 and the stepping motor 15 are fixed in the corresponding placement grooves by screws.

[0028] The cleaning plate 4 includes an electric push rod 5, a plate body 6 and a cleaning tooth 7 connected to one end face of the plate body 6. The other end face of the plate body 6 is connected to the output end of the electric push rod 5. The other end of the electric push rod 5 is connected to the moving component. The scraper can gather the dust on the filter plate 2 together.

[0029] The cleaning teeth 7 are used to extend into the filter hole 3. An infrared sensor 8 is provided under the cleaning teeth 7. After the infrared sensor 8 senses the contact at the corresponding position, the stepper motor 15 stops moving. At the same time, the electric push rod 5 is pushed out. Since the contact position is measured and set, the cleaning teeth 7 can be pushed into the filter hole 3. Then the electric push rod 5 is reset, and the stepper motor 15 continues to drive the slide 16 to move to clean the next filter hole 3.

[0030] The cleaning tooth 7 includes a main body 9 and an adsorption head 10. The adsorption head 10 is made of silicone material. The cross-section of the adsorption head 10 is trapezoidal. A groove is provided at one end of the adsorption head 10. A first magnetic sheet 11 is adhered in the groove. A second magnetic sheet 12 is provided on the end face of the main body 9. The first magnetic sheet 11 and the second magnetic sheet 12 are magnetically attracted to each other. The adsorption head 10 made of silicone material has an adsorption effect on dust. The adsorption head 10 is connected to the main body 9 by magnetic attraction, and the dirty adsorption head 10 can be quickly replaced.

[0031] Working principle: First, the electric push rod 5, the stepper motor 15 and the infrared sensor 8 are started through the controller 17. Under the drive of the stepper motor 15, the slide 16 drives the cleaning plate 4 to reciprocate. When the infrared sensor 8 senses the contact, the stepper motor 15 stops moving. At the same time, the electric push rod 5 extends to push the cleaning plate 4 out until the cleaning teeth 7 extend into the filter hole 3. Then the electric push rod 5 is reset, and the stepper motor 15 continues to drive the cleaning plate 4 to move to clean the subsequent filter holes 3. Repeat the above operation to clean each filter hole 3 on the filter plate 2. The dirty adsorption head 10 can be replaced by separating the first magnetic sheet 11 and the second magnetic sheet 12.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
