Referring to fig. 6, the embodiment of the invention also provides a method for controlling cleaning of an orifice plate, which is implemented by adopting the orifice plate cleaning system provided by any technical scheme of the invention, and the method comprises the following steps:
step S100, detecting the liquid level of the cleaning liquid in the liquid storage device 2 and the liquid level of the waste liquid in the waste liquid recovery device 3.
Step 200, if the liquid level of the cleaning liquid is higher than the lower limit value of the first set range and the liquid level of the waste liquid is lower than the upper limit value of the second set range, the plate washer 1 is started.
The first setting range is, for example, 95% -45% of the volume of the liquid storage device 2. The upper limit of the first set range is 95% of the volume of the liquid storage device 2. The lower limit of the first setting range is 45% of the volume of the liquid storage device 2. The second setting range is, for example, 70% to 10% of the volume of the waste liquid recovery device 3. Then, the upper limit value of the second setting range is 70% of the volume of the waste liquid recovery device 3, and the lower limit value of the second setting range is 10% of the volume of the waste liquid recovery device 3.
After the trigger 1 is started, the first air inlet pipeline 22 of the liquid storage device 2 is opened to supplement the first liquid storage cavity 21a with air, so that the inside of the first liquid storage cavity 21a is positive air pressure. The cleaning liquid is discharged to the cleaning area along the first liquid outlet pipe 24 under the positive pressure provided inside the liquid storage device 2. The plate washer 1 works normally to clean the aperture plate.
In some embodiments, the aperture plate washing control method further comprises the steps of:
step S300, if the liquid level of the cleaning liquid in the liquid storage device 2 is lower than the lower limit value of the first set range, stopping the plate washer 1. The liquid level of the cleaning liquid is lower than the lower limit value of the first set range, which means that the amount of the cleaning liquid in the liquid storage device 2 is too small to complete the cleaning operation. At this time, the controller controls the trigger 1 to stop and then controls the first pump 7 to start, and the first pump 7 pumps the cleaning liquid into the liquid storage device 2 to add the cleaning liquid to the liquid storage device 2. When the level of the cleaning liquid reaches the upper limit value of the first set range, it is indicated that the cleaning liquid in the liquid storage device 2 is sufficient and the first pump 7 is stopped.
Step 400, the cleaning solution is supplemented to the liquid storage device 2 until the liquid level of the cleaning solution reaches the upper limit value of the first set range. The upper limit of the first setting range is, for example, 95% of the volume of the liquid storage device 2. When the cleaning liquid reaches the upper limit value of the first set range, which means that the amount of cleaning liquid in the liquid storage device 2 is already sufficient, the plate washer 1 can use these cleaning liquids to complete the cleaning operation.
In some embodiments, the reservoir 2 is replenished with cleaning fluid in the following manner: the first pump 7 of the orifice plate cleaning system is turned on and the cleaning liquid is replenished to the liquid storage device 2 via the first pump 7 and the first liquid inlet pipe 25.
In some embodiments, the aperture plate washing control method further comprises the steps of:
step S500, if the liquid level of the waste liquid in the waste liquid recovery device 3 is higher than the upper limit value of the second set range, the plate washer 1 is stopped. The upper limit value of the second setting range is, for example, 70% of the volume of the waste liquid recovery device 3. When the liquid level of the waste liquid reaches the upper limit value of the second set range, which means that there is a relatively large amount of waste liquid in the waste liquid recovery device 3, there may be insufficient volume to store the waste liquid generated by the plate washer 1, so that the plate washer 1 needs to be stopped to avoid the phenomenon that the waste liquid is sucked into the plate washer 1 reversely, thereby causing the plate washer 1 to malfunction.
If the liquid level of the waste liquid in the waste liquid recovery device 3 is higher than the upper limit value of the second set range, the waste liquid in the waste liquid recovery device 3 is excessive; if not discharged, it may cause waste liquid in the washing area not to enter the waste liquid recovery device 3, and may also cause waste liquid to be sucked back, causing malfunction of the panel washer 1. Therefore, it is necessary to stop the plate washer 1 at this time.
And step S600, discharging the waste liquid in the waste liquid recovery device 3 until the liquid level of the waste liquid reaches the lower limit value of the second set range. Then, the lower limit value of the second setting range is 10% of the volume of the waste liquid recovery device 3.
In some embodiments, the waste liquid in the waste liquid recovery device 3 is discharged by the following steps: the second pump 8 of the orifice plate cleaning system is activated and the waste liquid is discharged out of the waste liquid recovery device 3 via the second pump 8 and the second liquid outlet pipe 33. The second pump 8 adopts a peristaltic pump, and the discharge amount of the waste liquid can be accurately controlled through the peristaltic pump.
As can be seen from the above-described shutdown conditions of the plate washer 1 and the above-described shutdown conditions of the plate washer 1, the plate washer 1 is shutdown when any one of the following conditions is satisfied: the liquid level of the cleaning liquid in the liquid storage device 2 is lower than the lower limit value of the first set range, and the liquid level of the waste liquid is higher than the upper limit value of the second set range. The plate washer 1 is started up only when the following two conditions are met simultaneously: the liquid level of the cleaning liquid in the liquid storage device 2 is higher than the lower limit value of the first set range, and the liquid level of the waste liquid is lower than the upper limit value of the second set range.
According to the pore plate cleaning control method provided by the technical scheme, whether the liquid level of the liquid storage device 2 is too low or not and whether the liquid level of the waste liquid in the waste liquid recovery device 3 is too high or not can be automatically identified, and the plate washer 1 is automatically stopped under the conditions that cleaning is impossible and liquid draining is impossible, so that the phenomenon of failure of the plate washer 1 caused by reverse suction of the waste liquid into the plate washer 1 is reduced; and can realize that washing liquid is automatic to be replenished, waste liquid is discharged automatically, does not need artifical frequent fluid replacement, flowing back, has saved the manpower, efficient.
