When the second switching device 650 is in the fourth state, the cleaning head 100 is disconnected from the cleaning agent storage 300, and the cleaning head 100 is communicated with the atmosphere, so that the gas in the atmosphere can enter from the second switching device 650 and be discharged from the cleaning head 100 under the action of the second power unit 500, and the gas can discharge the residual cleaning agent in the pipeline from the cleaning head 100, thereby avoiding the dripping of the cleaning head 100 during the subsequent operation.

Referring to fig. 7 in conjunction with fig. 8, in some embodiments, the waste liquid treatment system 10 includes a first detection unit 710, a second detection unit 720, a controller 730 and an alarm 740. The first detection unit 710 is used to detect the amount of waste liquid in the waste liquid storage 200. The second detection unit 720 is used for detecting the amount of the washing agent in the washing agent reservoir 300. The controller 730 is electrically connected to the first detection unit 710 and the second detection unit 720, and the controller 730 is configured to send an alarm signal when a detection value of the first detection unit 710 is greater than a first threshold value or a detection value of the second detection unit 720 is less than a second threshold value. An alarm 740 is electrically connected to the controller 730, the alarm 740 being configured to alarm when it receives an alarm signal.

For example, the first detection unit 710 may include a photoelectric sensor, and the first detection unit 710 determines the amount of waste liquid in the waste liquid tank 200 by determining the liquid level of waste liquid in the waste liquid tank 200.

The second detection unit 720 is a detection structure capable of detecting the amount of the detergent in the detergent reservoir 300. For example, the second detection unit 720 may include a camera and a graphic processing module, and the camera is electrically connected to the graphic processing module. The camera may capture an image of the cleaning agent reservoir 300 and the graphics processing module may then capture the amount of cleaning agent in the cleaning agent reservoir 300 by processing the image.

The controller 730 is a master device that controls the operation of a target according to a predetermined program. The Controller 730 may be a Central Processing Unit (CPU), an Electronic Control Unit (ECU), a Programmable Logic Controller (PLC), or the like.

For example, the alarm 740 may be a buzzer. As another example, alarm 740 includes a plurality of colored LED lights that illuminate different colors to provide an alarm.

The detection of the amount of waste liquid in the waste liquid storage 200 is realized by arranging the first detection unit 710, so that the amount of waste liquid in the waste liquid storage 200 can be conveniently detected. When the amount of waste liquid in waste reservoir 200 is greater than the first threshold, controller 730 controls alarm 740 to alarm to give a prompt to drain waste reservoir 200. The second detection unit 720 is arranged to detect the amount of the detergent in the detergent reservoir 300, so that the amount of the detergent in the detergent reservoir 300 can be detected conveniently. When the amount of the cleaning agent in the cleaning agent reservoir 300 is less than the second threshold, the controller 730 controls the alarm 740 to alarm to give an indication to replenish the cleaning agent in the cleaning agent reservoir 300.

In some embodiments, the first detection unit 710 is a load cell, and the first detection unit 710 is disposed at the bottom of the waste reservoir 200. And/or the second sensing unit 720 is a load cell, the second sensing unit 720 being placed at the bottom of the detergent reservoir 300.

The load cell is a detecting instrument capable of measuring the weight of a target member. The use of a load cell to measure the amount of waste fluid in the waste reservoir 200 and/or the amount of detergent in the detergent reservoir 300 provides a higher reliability and at a lower cost. Specifically, when the load cell detects that the weight of waste reservoir 200 is greater than the first threshold, indicating that the amount of waste liquid in waste reservoir 200 is large and is about to reach or has reached the maximum storage value of waste reservoir 200, controller 730 controls alarm 740 to issue an alarm to indicate that waste liquid in waste reservoir 200 is drained. When the load cell detects that the weight of the washer reservoir 300 is less than the second threshold, indicating that the amount of washer in the washer reservoir 300 is low, is about to be depleted, or has been depleted, the controller 730 controls the alarm 740 to alarm, giving an indication to replenish the washer in the washer reservoir 300.

Referring to fig. 9, in some embodiments, the waste liquid treatment system 10 includes a driving mechanism 800, the driving mechanism 800 is connected to the cleaning head 100, and the driving mechanism 800 is used for adjusting the position of the cleaning head 100 in the space so that the cleaning head 100 can extend into or withdraw from the container. By providing the driving mechanism 800, the cleaning head 100 can be conveniently adjusted to the position of the container, so that the cleaning head 100 can extend into or withdraw from the container, and the flexibility of the waste liquid treatment system 10 in treating waste liquid in containers at different positions is increased.

Optionally, drive mechanism 800 includes a frame 810, a lateral drive mechanism 820, and a vertical drive mechanism 830. The horizontal driving mechanism 820 is connected to the rack 810 and the vertical driving mechanism 830, and the horizontal driving mechanism 820 can drive the vertical driving mechanism 830 to move horizontally relative to the rack 810. The vertical driving mechanism 830 is connected to the cleaning head 100, and the vertical driving mechanism 830 can drive the cleaning head 100 to move vertically relative to the frame 810. Thus, the cleaning head 100 can be moved in the lateral and vertical directions by the cooperation of the lateral driving mechanism 820 and the vertical driving mechanism 830.

In some embodiments, the lateral drive mechanism 820 includes a drive member coupled to a drive pulley of a pulley mechanism and a pulley mechanism, and the vertical drive mechanism 830 is coupled to a belt of the pulley mechanism. When the driving member moves, the driving member can drive the driving wheel of the belt wheel mechanism to rotate, the driving wheel of the belt wheel mechanism is matched with the driven wheel to realize the movement of the transmission belt, and then the vertical moving mechanism is driven to move transversely relative to the rack 810. In order to improve the moving stability of the vertical moving mechanism, a slide rail extending in the transverse direction may be further disposed on the frame 810, so that the slide rail is in sliding fit with the vertical moving mechanism.

Referring to fig. 9, in some embodiments, the vertical moving mechanism includes a motor 831, a screw 832, a movable seat 833, a guide rail 834, and a mounting seat 835. Wherein, the mounting base 835 is connected to the transverse driving mechanism 820, and the guide rail 834 is connected to the mounting base 835 and extends along the vertical direction. The movable seat 833 is slidably engaged with the guide rail 834, so that the movable seat 833 is longitudinally movably disposed on the mounting seat 835. The cleaning head 100 is connected to the movable holder 833. The motor 831 is installed in the mount 835, the output end of the motor 831 is connected with one end of the lead screw 832, the other end of the lead screw 832 is rotatably arranged in the mount 835, and the movable seat 833 is in threaded connection with the lead screw 832. When the motor 831 rotates, the screw 832 is driven to rotate, and the movable seat 833 can only vertically move relative to the mounting seat 835, but cannot rotate relative to the mounting seat 835, so that the movable seat 833 in threaded connection with the screw 832 is driven by the screw 832 to vertically move relative to the mounting seat 835, and further drives the cleaning head 100 connected with the movable seat 833 to vertically move.

It should be noted that the embodiments of the lateral drive mechanism 820 and the vertical drive mechanism 830 may be interchanged. In addition, the horizontal driving mechanism 820 and the vertical driving mechanism 830 may further include linear driving members such as a linear electric cylinder, a linear air cylinder, and a linear oil cylinder, which are directly driven to realize the horizontal movement or the vertical movement. Additionally, drive mechanism 800 may also include a longitudinal drive mechanism to effect longitudinal movement of cleaning head 100. The specific structure of the longitudinal driving mechanism can refer to the transverse driving mechanism 820 and the vertical driving mechanism 830, which are not described herein again. Thus, the cleaning head 100 can be moved in the lateral, longitudinal and vertical directions, and three-axis movement of the cleaning head 100 in space is realized.

Referring to fig. 9, in some embodiments, the waste liquid treatment system 10 includes a plurality of cleaning heads 100, and each of the plurality of cleaning heads 100 is in communication with a waste liquid reservoir 200 and a cleaning agent reservoir 300. Through setting up a plurality of cleaning heads 100, be convenient for handle the waste liquid in a plurality of containers simultaneously, promote the treatment effeciency.

Referring to fig. 9 in conjunction with fig. 10, in some embodiments, the cleaning head 100 includes a tube 160 having one end for drawing waste fluid from the container to the waste reservoir 200 and/or injecting cleaning agent into the container. A groove 161 is formed on the end surface of the one end, and the groove 161 communicates the inner wall and the outer wall of the tube 160. Through set up the recess 161 of intercommunication body 160 inner wall and outer wall on the terminal surface that stretches into the container of body 160 for the one end of body 160 still can be through the waste liquid in the suction vessel of recess 161 when contacting with the diapire of container, thereby avoid the one end of body 160 to be taken place by the unable condition of suction waste liquid of the diapire shutoff of container when contacting with the diapire of container.

In other embodiments, one end of the tube 160 is used for pumping the waste liquid in the container to the waste liquid storage 200 and/or injecting the cleaning agent into the container, and a through hole is formed on the circumferential surface of the tube 160, and the through hole penetrates through the inner wall and the outer wall of the tube 160, and the through hole is formed near the one end. The waste liquid in the container can still be sucked through the through holes when one end of the tube body 160 is in contact with the bottom wall of the container, and the situation that the waste liquid cannot be sucked due to the fact that one end of the tube body 160 is plugged by the bottom wall of the container when the end of the tube body is in contact with the bottom wall of the container is avoided.

Some of the above embodiments provide that the waste treatment system 10 operates as follows:

first, the cleaning head 100 is inserted into the container by the driving mechanism 800 such that the first liquid port 110 is close to the bottom of the container. After the first switching device 610 is switched to the first state, the first power unit 400 is activated to provide power to the cleaning head 100 to draw the waste liquid in the container to the waste liquid storage 200. After the waste liquid in the container is sucked, the first power unit 400 is stopped after delaying for 5-10 s, and the waste liquid in the pipeline is ensured to be sucked into the waste liquid storage 200. The first switching device 610 is then switched to the second state, the second switching device 650 is switched to the third state, and the driving mechanism 800 adjusts the position of the cleaning head 100 so that the first port 110 is close to the top of the container. The second power unit 500 is activated to provide power to the cleaning head 100 to inject cleaning agent into the container. And then the second switching device 650 is switched to the fourth state, the second power unit 500 provides power to make the gas in the atmosphere enter from the second switching device 650 and be discharged from the cleaning head 100 under the action of the second power unit 500, and the gas can discharge the residual cleaning agent in the pipeline from the cleaning head 100, so as to avoid the dripping of the cleaning head 100 in the subsequent operation. The first fluid port 110 of the cleaning head 100 is then adjusted by the drive mechanism 800 to be near the bottom of the container. When the first switching device 610 is switched to the first state again, the first power unit 400 is activated to provide power to the cleaning head 100 to pump the waste liquid in the container to the waste liquid storage 200. After the waste liquid in the container is sucked, the first power unit 400 is stopped after delaying for 5-10 s, the waste liquid in the pipeline is ensured to be sucked into the waste liquid storage device 200, and the treatment of the waste liquid in the container can be completed.

Referring to fig. 11, in some embodiments, the waste liquid treatment system 10 includes a first flow channel 910 and a second flow channel 920 that are independent of each other. The first flow channel 910 is connected to the waste liquid container 200 and the cleaning head 100, and the second flow channel 920 is connected to the cleaning agent container 300 and the cleaning head 100. The cleaning head 100 has a suction port 140 and a liquid injection port 150 which are independent of each other, the suction port 140 communicates with the first flow path 910, and the suction port 140 is used for drawing the waste liquid in the container to the first flow path 910. The liquid inlet 150 communicates with the second flow path 920, and the liquid inlet 150 is used for injecting the cleaning agent in the second flow path 920 into the container.

The "first flow channel 910 and the second flow channel 920 which are independent of each other" means that the first flow channel 910 and the second flow channel 920 do not share a common portion, and the waste liquid flowing in the first flow channel 910 and the cleaning agent flowing in the second flow channel 920 do not interfere with each other.

The phrase "the cleaning head 100 has the suction port 140 and the liquid pouring port 150 which are independent of each other" means that the cleaning head 100 is provided with the suction port 140 for sucking the waste liquid and the liquid pouring port 150 for pouring the cleaning agent into the container separately, and the suction port 140 and the liquid pouring port 150 are two different openings.

Because the first flow channel 910 and the second flow channel 920 are independent of each other, and the suction port 140 communicating with the first flow channel 910 and the injection port 150 communicating with the second flow channel 920 are independent of each other, the waste liquid pumped from the container by the suction port 140 enters the waste liquid storage 200 and the cleaning agent in the cleaning agent storage 300 through the first flow channel 910 and is injected into the container through the injection port 150 through the second flow channel 920 without mutual interference, and the suction port 140 can simultaneously suck the waste liquid and the injection port 150 can inject the cleaning agent, so that when the injection port 150 injects the cleaning agent into the container, the suction port 140 can suck the waste liquid in the container, and the suction port 140 does not need to start sucking after the injection port 150 completes injection, thereby reducing the waiting time and improving the cleaning efficiency.

In some embodiments, the first flow passage 910 is a conduit connecting the cleaning head 100 and the waste reservoir 200. The second flow passage 920 is a pipe connecting the cleaning head 100 and the cleaning agent reservoir 300. The cleaning head 100 includes two tubes 160, one tube 160 communicating with the conduit connecting the cleaning head 100 and the waste reservoir 200 and forming a suction port 140 at its end remote from the conduit connecting the cleaning head 100 and the waste reservoir 200. The other tube 160 communicates with a pipe connecting the cleaning head 100 and the detergent reservoir 300, and forms a liquid pouring port 150 at its end remote from the pipe connecting the cleaning head 100 and the detergent reservoir 300.

Referring to FIG. 12, in some embodiments, the liquid injection port 150 is higher than the suction port 140.

"the height of the liquid pouring port 150 is higher than the height of the suction port 140" may also be understood as meaning that the length of the liquid pouring port 150 from the main body portion of the cleaning head 100 is shorter than the length of the suction port 140 from the main body portion of the cleaning head 100.

By making the height of the pouring port 150 higher than the height of the suction port 140, the inner wall of the container can be cleaned when the pouring port 150 pours liquid into the container. In addition, the height of the suction port 140 is lower than that of the liquid injection port 150, so that the suction port 140 is close to the bottom wall of the container, the waste liquid in the container can be sufficiently sucked by the suction port 140, and the residual of the waste liquid in the container is reduced.

The waste liquid treatment system 10 as shown in fig. 12 is operated as follows:

first, the cleaning head 100 is extended into the container by the driving mechanism 800 so that the suction port 140 is close to the bottom of the container. First power unit 400 is then activated to provide power to cause cleaning head 100 to draw waste liquid from the container into waste reservoir 200. After the waste liquid in the container is sucked, the first power unit 400 is stopped after delaying for 5-10 s, and the waste liquid in the pipeline is ensured to be sucked into the waste liquid storage 200. The second switching device 650 is then switched to a third state. The second power unit 500 is activated to provide power to the cleaning head 100 to inject cleaning agent into the container. After the cleaning agent is submerged a certain distance (e.g. 3-5 mm) through the suction port 140, the first power unit 400 is activated to provide power to make the cleaning head 100 pump the waste liquid in the container to the waste liquid storage 200. At this time, the first power unit 400 and the second power unit 500 are simultaneously operated. Here, the power levels of the first power unit 400 and the second power unit 500 are optionally similar or identical, so that the liquid level in the container remains constant. After the first power unit 400 and the second power unit 500 are simultaneously operated for a certain period of time, the injection of the cleaning agent is completed. The second switching device 650 is switched to the fourth state, the second power unit 500 provides power, so that air in the atmosphere enters from the second switching device 650 and is discharged from the cleaning head 100 under the action of the second power unit 500, the air can discharge residual cleaning agent in the pipeline from the cleaning head 100, and the cleaning head 100 is prevented from dripping in subsequent operation. Afterwards, the second power unit 500 stops working first, the first power unit 400 continues working, and the first power unit 400 is stopped after delaying for 5-10 s until the waste liquid in the container is pumped, so that the waste liquid in the pipeline is ensured to be sucked into the waste liquid storage 200, and the treatment of the waste liquid in the container can be completed.

Referring to fig. 13, the present embodiment further provides a treatment method based on the above-mentioned waste liquid treatment system 10. The processing method comprises the following steps:

step S1: pumping the waste liquid in the container to a waste liquid storage 200 through the cleaning head 100;

step S2: injecting a cleaning agent into the container through the cleaning head 100;

step S3: the waste liquid in the container is pumped out again to the waste liquid reservoir 200 by the cleaning head 100.

In some embodiments, in the step of drawing the waste liquid in the container to the waste liquid tank 200 through the cleaning head 100, the first power unit 400 is turned off with a delay after the waste liquid in the container is completely drawn. And/or in the step of pumping the waste liquid in the container to the waste liquid storage 200 again through the cleaning head 100, the first power unit 400 is turned off with a delay after the waste liquid in the container is pumped out.

The delayed turning off of the first power unit 400 means that the first power unit 400 is turned off after waiting for a predetermined time after the waste liquid in the container is completely pumped out. The preset time can be selected according to actual conditions. For example, the preset time can be 5-10 s.

By delaying the closing of the first power unit 400, it is ensured that waste fluid in the line between the cleaning head 100 and the waste reservoir 200 can be sucked into the waste reservoir 200 for storage.

Referring to fig. 14, in some embodiments, after the step of injecting the cleaning agent into the container through the cleaning head 100, the processing method further includes:

s4: gas is introduced into the waste fluid treatment system 10 to inject residual cleaning agent from the cleaning head 100 into the vessel.

By introducing gas into the waste liquid treatment system 10, residual cleaning agent is injected into the container from the cleaning head 100, so that the cleaning agent is prevented from remaining in the pipeline, and the cleaning head 100 is prevented from dripping during subsequent operation.
