After cleaning is completed, the remaining liquid is discharged through the drain pipe.

[0020] A method for cleaning equipment by deep cleaning with micro-nano bubbles, comprising the following steps: S1. The liquid used for cleaning is transported to the circulation chamber in the cleaning box through a one-way valve, and enters the micro-nano bubble generator through a circulation pipe. The liquid carrying micro-nano bubbles then enters the water distribution pipe and is sprayed out through a nozzle to supply the liquid carrying micro-nano bubbles to the cleaning chamber. When the liquid level overflows the circulation slot, it flows back to the circulation chamber, and then the sliding box is slid to adjust the position of the sewage suction horn at the bottom, and the sewage suction horn is floated above the liquid surface through a floating plate; S2. When placing the workpiece, remove the hook and hang the workpiece on the hook, then insert the hook into the slot to limit the workpiece, and clean the workpiece by spraying liquid with micro-nano bubbles; S3. While the liquid is cleaning the workpiece, the first motor starts and drives the bidirectional screw to rotate, and the rotating bidirectional screw drives the carrier to slide along the direction of the slide slot. When the carrier slides, it drives the cleaning brush to move synchronously. After the second motor starts, it drives one of the gears to rotate, and then cooperates with the toothed belt to drive the remaining gears to rotate synchronously, thereby driving the cleaning brush to rotate and brush the workpiece, so as to facilitate the adjustment of the distance between the cleaning brushes on both sides of the workpiece, and facilitate the brushing of workpieces of different volumes; S4. After scrubbing, the oil and impurities float above the liquid surface and flow into the circulation chamber with the flow of the liquid surface. After the oil and impurities follow the liquid to overflow the circulation groove, they preferentially flow into the circulation chamber on one side of the partition. As the liquid surface rises, the oil and impurities follow the liquid to overflow the partition again, so as to prevent the oil and impurities from contaminating the liquid at the bottom of the circulation chamber on the other side of the partition, and prevent the oil and impurities from being sucked into the circulation pipe, causing the micro-nano bubble generator to be contaminated, and at the same time prevent the oil and impurities from following the liquid circulation back to the cleaning chamber; S5. When the sewage pump is started, oil and impurities are sucked into the longitudinal folded pipe along with part of the liquid through the sewage suction horn, and then enter the sewage pump through the transfer sliding box and the transverse folded pipe in turn, and finally discharged through the sewage pump; S6. When cleaning is completed, turn the handwheel to drive the screw to rotate, and the rotating screw drives the dirt separation plate to slide downward to adjust the height of the dirt separation plate so that the bottom of the dirt separation plate moves to the liquid surface. When the carrying frame moves to both sides, it drives the dirt separation mechanism to move synchronously, and pushes the oil and impurities to both sides through the dirt separation plate to avoid a large amount of oil and impurities staying above the liquid where the workpiece is located, and moves the dirt suction horn to the liquid surface where the workpiece is located to absorb the remaining oil and impurities, reduce the amount of oil and impurities on the liquid surface, and when taking out the workpiece, avoid a large amount of oil and impurities re-attaching to the workpiece when the workpiece is taken out, optimize the cleaning effect, and the remaining liquid is discharged through the drain pipe.

[0021] The beneficial effects of the present invention are as follows: By setting a brushing mechanism, the first motor drives the bidirectional screw to rotate after starting, and the rotating bidirectional screw drives the carrying frame to slide. When the carrying frame slides, it drives the cleaning brush to move synchronously. The second motor cooperates with the toothed belt to drive the gear to rotate synchronously, and then drives the cleaning brush to rotate to brush the workpiece, which is convenient for adjusting the distance between the cleaning brushes on both sides of the workpiece, and convenient for brushing workpieces of different volumes. By setting up a dirt separation mechanism, turning the hand wheel drives the screw to rotate, and the rotating screw drives the dirt separation plate to slide downward, so as to adjust the height of the dirt separation plate, so that the bottom of the dirt separation plate moves to the liquid surface, and when the carrier moves to both sides, the dirt separation mechanism is driven to move synchronously, and the oil and impurities are pushed to both sides through the dirt separation plate, so as to avoid a large amount of oil and impurities staying above the liquid where the workpiece is located; By setting up a sewage discharge mechanism in conjunction with the sewage separation mechanism, after the sewage pump is started, oil and impurities are sucked into the longitudinal folding pipe along with part of the liquid through the sewage suction horn, and then enter the sewage pump through the transfer sliding box and the transverse folding pipe in turn, and are finally discharged through the sewage pump, thereby reducing the amount of oil and impurities on the liquid surface. When the workpiece is taken out, it is avoided that a large amount of oil and impurities are re-attached to the workpiece when the workpiece is taken out, thereby optimizing the cleaning effect, saving time for cleaning oil and impurities, and improving the cleaning efficiency.

When the carrying frame 503 moves to both sides, it drives the dirt separating mechanism 6 to move synchronously, and pushes the oil and impurities to both sides through the dirt separating plate 602 to avoid a large amount of oil and impurities staying above the liquid where the workpiece is located, and moves the dirt suction horn 806 to the liquid surface where the workpiece is located to absorb the remaining oil and impurities, reduce the amount of oil and impurities on the liquid surface, and take out the workpiece to avoid a large amount of oil and impurities from re-attaching to the workpiece when the workpiece is taken out, thereby optimizing the cleaning effect, and the remaining liquid is discharged through the drain pipe 9.

10. A method for cleaning equipment by deep cleaning with micro-nano bubbles, using the equipment according to any one of claims 1 to 9, comprising the following steps: S1. The liquid used for cleaning is transported to the circulation chamber (3) in the cleaning box (1) through the one-way valve (11), and enters the micro-nano bubble generator (1201) through the circulation pipe (1202). The liquid carrying the micro-nano bubbles then enters the water distribution pipe (1203) and is sprayed out through the nozzle (1204) to supply the liquid carrying the micro-nano bubbles to the cleaning chamber (2). When the liquid level overflows the circulation groove (13), it flows back to the circulation chamber (3), and then the sliding box (803) is slid to adjust the position of the sewage suction horn (806) at the bottom thereof, and the sewage suction horn (806) is floated above the liquid level through the floating plate (807); S2, when placing a workpiece, remove the hook (703) and hang the workpiece on the hook (703), then insert the hook (703) into the slot (702), so as to limit the position of the workpiece, and clean the workpiece by spraying liquid containing micro-nano bubbles; S3. While the workpiece is being cleaned by the liquid, the motor 1 (502) is started to drive the bidirectional screw (501) to rotate, and the rotating bidirectional screw (501) drives the carrier (503) to slide along the direction of the slide groove (4). When the carrier (503) slides, it drives the cleaning brush (505) to move synchronously. After the motor 2 (504) is started, it drives one of the gears (507) to rotate, and then cooperates with the toothed belt (506) to drive the remaining gears (507) to rotate synchronously, thereby driving the cleaning brush (505) to rotate to clean the workpiece, so that the distance between the cleaning brushes (505) on both sides of the workpiece can be adjusted, so that workpieces of different sizes can be cleaned; S4, the oil and impurities after scrubbing float to the surface of the liquid and flow into the circulation chamber (3) along with the flow of the liquid surface. After the oil and impurities follow the liquid to overflow the circulation groove (13), they preferentially flow into the circulation chamber (3) on one side of the partition (10). As the liquid surface rises, the oil and impurities follow the liquid to overflow the partition (10) again, thereby preventing the oil and impurities from contaminating the liquid at the bottom of the circulation chamber (3) on the other side of the partition (10), preventing the oil and impurities from being sucked into the circulation pipe (1202) and causing the micro-nano bubble generator (1201) to be contaminated. At the same time, preventing the oil and impurities from following the liquid circulation back into the cleaning chamber (2); S5. When the sewage pump (802) is started, the oil and impurities are sucked into the longitudinal folded pipe (805) along with part of the liquid through the sewage suction horn (806), and then enter the sewage pump (802) through the transfer sliding box (803) and the transverse folded pipe (804) in sequence, and finally discharged through the sewage pump (802); S6. After the cleaning is completed, the hand wheel (604) is rotated to drive the screw (603) to rotate, and the rotating screw (603) drives the dirt separation plate (602) to slide downward, thereby adjusting the height of the dirt separation plate (602) so that the bottom of the dirt separation plate (602) moves to the liquid surface. When the carrier (503) moves to both sides, the dirt separation mechanism (6) is driven to move synchronously, and the oil and impurities are pushed to both sides through the dirt separation plate (602) to avoid a large amount of oil and impurities staying above the liquid where the workpiece is located. The dirt suction horn (806) is moved above the liquid surface where the workpiece is located to absorb the remaining oil and impurities, reduce the amount of oil and impurities on the liquid surface, and when the workpiece is taken out, it is avoided that a large amount of oil and impurities are re-attached to the workpiece when the workpiece is taken out, thereby optimizing the cleaning effect, and the remaining liquid is discharged through the drain pipe (9).
