Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly to an equipment and method for deep cleaning by micro-nano bubbles. Background Art

[0002] The cleaning equipment can replace manual labor to clean the oil stains and impurities on the surface of workpieces, avoiding the influence of the residual oil stains and impurities on the subsequent electroplating process of the workpieces. After micro-nano bubbles are incorporated into the cleaning liquid, the oil stains and impurities can be adsorbed by the micro-nano bubbles, optimizing the cleaning effect and facilitating the deep cleaning of the workpieces.

[0003] The patent document with the publication number of "CN114833131B" discloses "an automatic micro-nano bubble cleaning equipment, including a base, on which an immersion tank is installed, and a micro-nano bubble generator is installed on one side wall of the immersion tank. Different from the prior art, this invention can realize the integrated cleaning operation of immersion and rinsing, with good cleaning effect, and the micro-nano bubble generator and the stirring mechanism are added to further improve the cleaning effect. At the same time, during the whole cleaning process, only the workpiece to be cleaned needs to be placed in the washing hopper manually, and the rest of the cleaning work runs automatically, with high cleaning efficiency, and can realize the recycling of the cleaning liquid, saving resources. Only by controlling the forward and reverse rotation of the first motor through the PLC controller, the use of other electrical components is reduced, and the damage rate is lower, and it is also convenient for maintenance and replacement after damage in the later stage". Although it can realize the integrated cleaning operation of immersion and rinsing, with good cleaning effect, and the micro-nano bubble generator and the stirring mechanism are added to further improve the cleaning effect, after the workpiece is cleaned, the oil stains and impurities will float on the liquid surface of the cleaning liquid. When the workpiece is taken out, the oil stains and impurities will reattach to the surface of the workpiece, causing secondary pollution. At the same time, the residual oil stains and impurities are not conducive to the subsequent cleaning of the workpiece, and need to be cleaned manually regularly, which is rather troublesome and will reduce the cleaning efficiency.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

The special-shaped column is fixedly connected to the box body of the cleaning tank by bolts.

[0008] Specifically, it absorbs residual oil stains and impurities, reduces the amount of oil stains and impurities on the liquid surface, and when taking out the workpiece, it avoids a large amount of oil stains and impurities reattaching to the workpiece when the workpiece is taken out, optimizing the cleaning effect.

[0009] As a further solution of the present invention, the brushing mechanism includes a bidirectional lead screw. Two threads with the same length and opposite directions are provided on the outer ring of the bidirectional lead screw. One end of the bidirectional lead screw is fixedly installed with a motor one. Mounting frames are threadedly connected to both ends of the outer ring of the bidirectional lead screw. Sliding grooves are opened at the front and rear ends of the top of the cleaning tank. The mounting frames are slidably connected to the cleaning tank through the sliding grooves.

[0010] Specifically, it is convenient to adjust the distance between the two mounting frames.

[0011] As a further solution of the present invention, the brushing mechanism further includes a motor two fixedly installed on the top of the mounting frame. A toothed belt is arranged inside the mounting frame. A number of gears are meshed inside the toothed belt. The shafts at the top and bottom of the gears are movably connected to the mounting frame. A cleaning brush is installed at the bottom of the gear. The shaft of the cleaning brush is fixedly connected to the shaft of the gear by bolts. The shaft at the top of one of the gears is fixedly connected to the output shaft of the motor two.

[0012] Specifically, it is convenient to adjust the distance between the cleaning brushes on both sides of the workpiece, facilitating the brushing of workpieces of different volumes and optimizing the cleaning effect.

[0013] As a further solution of the present invention, the oil separation mechanism includes a gantry. A separation plate is slidably connected between the two side frames of the gantry. A screw rod is centrally threadedly connected through the top frame of the gantry. A handwheel is fixedly installed at the top of the screw rod. The bottom of the screw rod is movably connected to a transfer member through a bearing, and the transfer member is fixedly connected to the separation plate by bolts.

[0014] As a further solution of the present invention, the gantry is fixedly connected to the carrying frame, the gantry is sleeved with a bidirectional lead screw, and the gantry is slidably connected to the cleaning tank through a chute.

[0015] Specifically, the separation plate is used to push the oil stains and impurities to both sides, preventing a large amount of oil stains and impurities from staying above the liquid where the workpiece is located.

[0016] As a further solution of the present invention, the micro-nano generation mechanism includes a micro-nano bubble generator. A water distribution pipe is fixedly installed on one side of the micro-nano bubble generator. A plurality of nozzles are threadedly connected through the top of the water distribution pipe. A circulation pipe is fixedly installed at the other end of the micro-nano bubble generator.

[0017] As a further solution of the present invention, the micro-nano bubble generator, the circulation pipe and the water distribution pipe are all located inside the bottom box body of the cleaning tank. The circulation pipe is communicated with the circulation cavity, and the nozzles penetrate through the inner wall of the bottom box body of the cleaning tank.

[0018] Specifically, it is convenient to supply the liquid carrying micro-nano bubbles.

[0019] As a further solution of the present invention, the suspension mechanism includes a hanging rack. A plurality of card slots are opened through both sides of the hanging rack. Hooks are clamped inside the card slots. The hanging rack is fixedly connected to the box body of the cleaning tank by bolts.

[0020] Specifically, it is convenient to limit the workpiece and facilitate the cleaning of the workpiece.

[0021] As a further solution of the present invention, a partition is fixedly installed inside the cleaning tank at the middle position of the circulation cavity. The height difference between the top of the partition and the bottom of the flow channel is 10 cm. A drain pipe is fixedly installed through the box body of the cleaning tank and close to the cleaning cavity side.

[0022] Specifically, it prevents oil stains and impurities from being sucked into the circulation pipe, resulting in contamination of the micro-nano bubble generator. At the same time, it prevents oil stains and impurities from returning to the cleaning cavity along with the liquid circulation. After the cleaning is completed, the remaining liquid is discharged through the drain pipe.

[0023] A cleaning method for an equipment for deep cleaning by micro-nano bubbles includes the following steps:

[0024] S1. The liquid for cleaning is conveyed through a one-way valve into the circulation chamber in the cleaning tank, enters the micro-nano bubble generator through a circulation pipe, and then the liquid carrying micro-nano bubbles 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 flow-through groove, it flows back into the circulation chamber. Then, slide and transfer the sliding box to adjust the position of the sewage suction horn at its bottom, and make the sewage suction horn float on the liquid surface through a floating plate.

[0025] S2. When placing the workpiece, remove the hook and hang the workpiece on the hook, and then snap the hook into the card slot to facilitate limiting the workpiece. Clean the workpiece with the sprayed liquid carrying micro-nano bubbles.

[0026] S3. While the liquid is cleaning the workpiece, after the first motor starts, it drives the bidirectional lead screw to rotate. The rotating bidirectional lead screw drives the carrier frame to slide along the direction of the chute. When the carrier frame 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 to brush the workpiece, which is convenient for adjusting the distance between the cleaning brushes on both sides of the workpiece and facilitating brushing workpieces of different volumes.

[0027] S4. The oil stains and impurities after brushing float to the liquid surface of the liquid and flow into the circulation chamber along with the flow of the liquid surface. After the oil stains and impurities follow the liquid to overflow the flow-through groove, they preferentially flow into the circulation chamber on one side of the partition. As the liquid level rises, the oil stains and impurities follow the liquid to overflow the partition again, avoiding the oil stains and impurities from polluting the liquid at the bottom of the circulation chamber on the other side of the partition, preventing the oil stains and impurities from being sucked into the circulation pipe and causing pollution to the micro-nano bubble generator, and at the same time avoiding the oil stains and impurities from following the liquid circulation and returning to the cleaning chamber again.

[0028] S5. When the sewage pump starts, the oil stains and impurities follow part of the liquid and are sucked into the longitudinal folding pipe through the sewage suction horn, and then enter the sewage pump through the transfer sliding box and the transverse folding pipe in sequence, and finally are discharged through the sewage pump.

[0029] S6. When the cleaning is completed, rotate the handwheel to drive the screw to rotate, and drive the sewage separation plate to slide down through the rotating screw, thereby adjusting the height of the sewage separation plate so that the bottom of the sewage separation plate moves to the liquid surface. When the carrier frame moves to both sides, it drives the sewage separation mechanism to move synchronously. The sewage separation plate pushes the oil stains and impurities to both sides, avoiding a large amount of oil stains and impurities from staying above the liquid where the workpiece is located, and moving the sewage suction horn to the liquid surface above the position where the workpiece is located to absorb the remaining oil stains and impurities, reducing the amount of oil stains and impurities on the liquid surface, and when taking out the workpiece, avoiding a large amount of oil stains and impurities from reattaching to the workpiece when taking out the workpiece, optimizing the cleaning effect. The remaining liquid is discharged through the drain pipe.

[0030] The beneficial effects of the present invention are as follows:

[0031] By setting up a scrubbing mechanism, when the first motor starts, it drives the bidirectional lead screw to rotate. The rotating bidirectional lead 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 gears to rotate synchronously, and then drives the cleaning brush to rotate to scrub the workpiece, which is convenient for adjusting the distance between the cleaning brushes on both sides of the workpiece and facilitates scrubbing workpieces of different volumes.

[0032] By setting up a sewage separation mechanism, rotating the handwheel drives the screw to rotate, and the rotating screw drives the sewage separation plate to slide downward, thereby adjusting the height of the sewage separation plate so that the bottom of the sewage separation plate moves to the liquid surface. When the carrying frame moves to both sides, it drives the sewage separation mechanism to move synchronously. The sewage separation plate pushes the oil stains and impurities to both sides, preventing a large amount of oil stains and impurities from staying above the liquid where the workpiece is located.

[0033] By setting up a sewage discharge mechanism in cooperation with the sewage separation mechanism, after the sewage pump is started, the oil stains and impurities follow part of the liquid and are sucked into the longitudinal folding pipe through the sewage suction horn, and then enter the sewage pump through the transfer sliding box and the transverse folding pipe in sequence, and finally are discharged through the sewage pump, reducing the amount of oil stains and impurities on the liquid surface. When the workpiece is taken out, it avoids a large amount of oil stains and impurities reattaching to the workpiece when the workpiece is taken out, optimizing the cleaning effect, saving the time for cleaning the oil stains and impurities at the same time, and improving the cleaning efficiency.

[0051] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0052] Such as Figures 1 - 10As shown in the figure, a device for deep cleaning by micro-nano bubbles includes a cleaning tank 1. A cleaning chamber 2 is provided through the top of the cleaning tank 1 near one side, and a circulation chamber 3 is provided through the top of the cleaning tank 1 near the other side. A brushing mechanism 5 is installed on the top of the cleaning tank 1 and above the cleaning chamber 2. Two sewage separation mechanisms 6 are installed on the top of the cleaning tank 1 and inside the brushing mechanism 5. A suspension mechanism 7 is installed at the center of the top of the cleaning tank 1 and above the cleaning chamber 2. A sewage discharge mechanism 8 is installed on the top of the cleaning tank 1 and above the circulation chamber 3. A micro-nano generation mechanism 12 is installed inside the bottom of the cleaning tank 1 and penetrates the inner wall of the bottom of the cleaning tank 1. A one-way valve 11 is fixedly installed on the box body of the cleaning tank 1 and near the circulation chamber 3. A flow channel 13 is provided at the top of the box body between the cleaning chamber 2 and the circulation chamber 3.

[0053] The sewage discharge mechanism 8 includes a special-shaped column 801. A sewage pump 802 is fixedly installed through the top of the vertical section of the special-shaped column 801. A transfer sliding box 803 is slidably connected through the top of the horizontal section of the special-shaped column 801. A horizontal folding pipe 804 is fixedly installed between the transfer sliding box 803 and the sewage pump 802.

A floating plate 807 is fixedly installed on the outer circle of the sewage suction horn 806. The special-shaped column 801 is fixedly connected to the box body of the cleaning tank 1 by bolts.

[0054] Specifically, the liquid for cleaning is transported to the circulation chamber 3 in the cleaning tank 1 through the one-way valve 11. After the liquid enters the micro-nano generation mechanism 12, it forms a liquid with micro-nano bubbles and sprays out, gradually filling the cleaning chamber 2. When the liquid level overflows the flow channel 13, it flows back to the circulation chamber 3. Then, slide the transfer sliding box 803 to adjust the position of the sewage suction horn 806 at its bottom, and make the sewage suction horn 806 float on the liquid surface through the floating plate 807. After that, hang the workpiece to be cleaned on the suspension mechanism 7, and clean the workpiece with the sprayed liquid with micro-nano bubbles. At the same time, the brushing mechanism 5 is started to brush the workpiece. The oil stains and impurities after brushing float to the liquid surface and flow into the circulation chamber 3 along with the flow of the liquid surface. When the sewage pump 802 is started, the oil stains and impurities are sucked into the vertical folding pipe 805 through the sewage suction horn 806 along with part of the liquid, and then enter the sewage pump 802 through the transfer sliding box 803 and the horizontal folding pipe 804 in sequence, and are finally discharged through the sewage pump 802. When the cleaning is completed, the oil stains and impurities on the liquid surface are pushed to both sides by the sewage separation mechanism 6, and the sewage suction horn 806 is moved to the liquid surface above the position of the workpiece to absorb the remaining oil stains and impurities, reducing the amount of oil stains and impurities on the liquid surface, and when taking out the workpiece, avoiding a large amount of oil stains and impurities reattaching to the workpiece, optimizing the cleaning effect.

[0055] The scrubbing mechanism 5 includes a bidirectional screw rod 501, the outer ring of which is provided with two sections of threads of the same length and opposite directions. A motor 502 is fixedly installed at one end of the bidirectional screw rod 501. The outer ring of the bidirectional screw rod 501 is threadedly connected to a carrying frame 503 at both ends. Slide grooves 4 are provided at the front and rear ends of the top of the cleaning box 1, and the carrying frame 503 is slidably connected to the cleaning box 1 through the slide grooves 4.

[0056] Specifically, after the motor 1 502 is started, it drives the bidirectional screw rod 501 to rotate, and the rotating bidirectional screw rod 501 drives the mounting frame 503 to slide along the direction of the slide groove 4, so as to facilitate the adjustment of the distance between the two mounting frames 503.

[0057] The scrubbing mechanism 5 also includes a motor 2 504 fixedly mounted on the top of the mounting frame 503, a toothed belt 506 is arranged inside the mounting frame 503, a plurality of gears 507 are meshedly connected inside the toothed belt 506, the shafts at the top and bottom of the gears 507 are movably connected to the mounting frame 503, a cleaning brush 505 is installed at the bottom of the gear 507, the shaft of the cleaning brush 505 is fixedly connected to the shaft of the gear 507 by bolts, and the shaft at the top of one of the gears 507 is fixedly connected to the output shaft of the motor 2 504.

[0058] Specifically, when the carrying frame 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 brush the workpiece, so as to facilitate the adjustment of the distance between the cleaning brushes 505 on both sides of the workpiece, facilitate the brushing of workpieces of different sizes, and optimize the cleaning effect.

[0059] The sewage separation mechanism 6 includes a gantry 601, and sewage separation plates 602 are slidably connected between the two side frames of the gantry 601. A screw rod 603 is threadedly connected in the center of the top frame that passes through the gantry 601. A hand wheel 604 is fixedly installed on the top of the screw rod 603. The bottom of the screw rod 603 is movably connected to a converter 605 through a bearing. The converter 605 is fixedly connected to the sewage separation plate 602 by bolts.

[0060] The gantry 601 is fixedly connected to the carrying frame 503 , the gantry 601 is sleeved with the bidirectional lead screw 501 , and the gantry 601 is slidably connected to the cleaning box 1 through the slide groove 4 .

[0061] Specifically, after cleaning is completed, the hand wheel 604 is rotated to drive the screw 603 to rotate, and the rotating screw 603 drives the dirt separating plate 602 to slide downward, so as to adjust the height of the dirt separating plate 602, and make the bottom of the dirt separating plate 602 move to the liquid surface. 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, so as to avoid a large amount of oil and impurities staying above the liquid where the workpiece is located.

[0062] The micro-nano generation mechanism 12 includes a micro-nano bubble generator 1201. A water distribution pipe 1203 is fixedly installed on one side of the micro-nano bubble generator 1201. A number of spray heads 1204 are threadedly connected through the top of the water distribution pipe 1203. The other end of the micro-nano bubble generator 1201 is fixedly installed with a circulation pipe 1202.

[0063] The micro-nano bubble generator 1201, the circulation pipe 1202 and the water distribution pipe 1203 are all located inside the bottom box body of the cleaning box 1. The circulation pipe 1202 is communicated with the circulation cavity 3. The spray heads 1204 penetrate through the inner wall of the bottom box body of the cleaning box 1.

[0064] Specifically, after the liquid enters the circulation cavity 3, it enters the micro-nano bubble generator 1201 through the circulation pipe 1202. Then, the liquid carrying micro-nano bubbles enters the water distribution pipe 1203 and is sprayed out through the spray heads 1204, which is convenient for supplying the liquid carrying micro-nano bubbles.

[0065] The suspension mechanism 7 includes a hanging rack 701. A number of clamping grooves 702 are opened through both sides of the hanging rack 701. A hanging hook 703 is clamped inside the clamping grooves 702. The hanging rack 701 is fixedly connected to the box body of the cleaning box 1 by bolts.

[0066] Specifically, after removing the hanging hook 703, the workpiece is hung on the hanging hook 703, and then the hanging hook 703 is clamped into the clamping groove 702, which is convenient for limiting the workpiece and facilitating the cleaning of the workpiece.

[0067] A partition plate 10 is fixedly installed inside the cleaning box 1 at the middle position of the circulation cavity 3. The height difference between the top of the partition plate 10 and the bottom of the flow-through groove 13 is 10 cm. A drain pipe 9 is fixedly installed through the box body of the cleaning box 1 and close to the side of the cleaning cavity 2.

[0068] Specifically, after the oil stains and impurities follow the liquid and overflow the flow-through groove 13, they preferentially flow into the circulation cavity 3 on one side of the partition plate 10. As the liquid level rises, the oil stains and impurities follow the liquid and overflow the partition plate 10, avoiding the oil stains and impurities from contaminating the liquid at the bottom of the circulation cavity 3 on the other side of the partition plate 10, preventing the oil stains and impurities from being sucked into the circulation pipe 1202 and causing pollution to the micro-nano bubble generator 1201. At the same time, it avoids the oil stains and impurities from following the liquid circulation and returning to the cleaning cavity 2 again. After the cleaning is completed, the remaining liquid is discharged through the drain pipe 9.

[0069] It should be noted that the present invention is a device for deep cleaning by micro-nano bubbles, including the following steps:

[0070] During use, the liquid for cleaning is conveyed through the one-way valve 11 to the circulation chamber 3 in the cleaning tank 1, enters the micro-nano bubble generator 1201 through the circulation pipe 1202, and then the liquid carrying micro-nano bubbles enters the water distribution pipe 1203 and is sprayed out through the spray head 1204 to supply the liquid carrying micro-nano bubbles to the cleaning chamber 2. When the liquid level rises above the flow-through groove 13, it flows back to the circulation chamber 3. Then, slide and transfer the sliding box 803 to adjust the position of the sewage suction horn 806 at its bottom, and make the sewage suction horn 806 float on the liquid surface through the floating plate 807;

[0071] When placing the workpiece, remove the hook 703 and then hang the workpiece on the hook 703, and then snap the hook 703 into the card slot 702 to facilitate the positioning of the workpiece, and clean the workpiece with the sprayed liquid carrying micro-nano bubbles;

[0072] While the liquid is cleaning the workpiece, the first motor 502 starts to drive the bidirectional lead screw 501 to rotate. The rotating bidirectional lead screw 501 drives the carrier frame 503 to slide along the direction of the chute 4. When the carrier frame 503 slides, it drives the cleaning brush 505 to move synchronously. The second motor 504 starts to drive 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 brush the workpiece, which is convenient for adjusting the distance between the cleaning brushes 505 on both sides of the workpiece and facilitating the brushing of workpieces of different volumes;

[0073] After brushing, the oil stains and impurities float to the liquid surface and flow into the circulation chamber 3 along with the flow of the liquid surface. After the oil stains and impurities follow the liquid and overflow the flow-through groove 13, they preferentially flow into the circulation chamber 3 on one side of the partition plate 10. As the liquid level rises, the oil stains and impurities follow the liquid and overflow the partition plate 10, avoiding the contamination of the liquid at the bottom of the circulation chamber 3 on the other side of the partition plate 10 by the oil stains and impurities, preventing the oil stains and impurities from being sucked into the circulation pipe 1202, resulting in the contamination of the micro-nano bubble generator 1201, and at the same time preventing the oil stains and impurities from following the liquid circulation and returning to the cleaning chamber 2 again;

[0074] When the sewage pump 802 starts, the oil stains and impurities follow part of the liquid and are sucked into the longitudinal folding pipe 805 through the sewage suction horn 806, and then enter the sewage pump 802 through the transfer sliding box 803 and the transverse folding pipe 804 in sequence, and finally are discharged through the sewage pump 802;

[0075] After the cleaning is completed, rotate the handwheel 604 to drive the screw rod 603 to rotate, and drive the sewage separation plate 602 to slide downward through the rotating screw rod 603, so as to adjust the height of the sewage separation plate 602, and move the bottom of the sewage separation plate 602 to the liquid surface. When the carrying frame 503 moves to both sides, drive the sewage separation mechanism 6 to move synchronously, and push the oil stains and impurities to both sides through the sewage separation plate 602, so as to prevent a large amount of oil stains and impurities from staying above the liquid where the workpiece is located, and move the sewage suction horn 806 above the liquid surface at the position where the workpiece is located to absorb the remaining oil stains and impurities, reduce the amount of oil stains and impurities on the liquid surface, and avoid a large amount of oil stains and impurities from reattaching to the workpiece when the workpiece is taken out, optimize the cleaning effect, and the remaining liquid is discharged through the drain pipe 9.

6. A cleaning method using micro-nano bubble deep cleaning, using the device for deep cleaning using micro-nano bubble as claimed in claim 5, 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.
