Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, what is meant is "including, but not limited to". The term "plurality" as used herein means two or more.
The control method of the equipment can be applied to the process that the tank body of the equipment needs to be continuously vacuumized and vacuumized, and can effectively reduce energy waste caused in the process of vacuumizing the tank body, so that the production and operation process of the equipment is more environment-friendly.
In a specific embodiment, as shown in fig. 1, the apparatus includes a plurality of tanks and a vacuum extractor for evacuating the tanks, and the control method includes:
controlling the vacuumizing device to vacuumize a first tank body in the plurality of tank bodies;

and after the pressures in the first tank body and the second tank body are balanced, controlling the first tank body to continuously discharge vacuum to a normal pressure state, and controlling the vacuumizing device to vacuumize the second tank body.
When the pressures in the first tank and the second tank are balanced, the first tank needs to be subjected to vacuum discharge operation so as to discharge the materials in the first tank. Since the interior of the first tank is changed from a vacuum state to a low-pressure state in the process of pressure equilibrium with the second tank, the time consumed for the evacuation operation of the first tank is shorter, and the interior of the first tank can reach a normal-pressure state more quickly. In the process that the first tank body is changed from a low-pressure state to a normal-pressure state, the pressure change impact on the materials in the first tank body is smaller, and the materials in the first tank body and the first tank body are not easily damaged. After the pressures in the first tank body and the second tank body are balanced, the internal part of the second tank body is changed from a normal pressure state to a low pressure state, and when the second tank body is vacuumized, the needed time is shorter, the consumed energy consumption is smaller, and the vacuumizing efficiency is higher.
Further, before the vacuumizing device is started, the first tank body is controlled to be communicated with the second tank bodies. Specifically, the tank bodies and the vacuumizing device are connected through pipelines, and a control device of the equipment can control the on-off of the pipelines so as to connect or disconnect the tank bodies or the tank bodies and the vacuumizing device.

In a specific embodiment, the device applied in the control method of the device is a stirring device for battery production, the tank body is a stirring tank, and the vacuumizing device is controlled to vacuumize the stirring tank before the stirring tank performs a stirring task. When the equipment is used for a long time, more dust and the like are accumulated in the pipeline, and in order to quickly clean the dust in the pipeline, the pipeline can be communicated with the external environment through a communication branch. When the pipeline needs to be cleaned, the communicating branch is controlled to be opened, the communicating branch is communicated with the first tank body, the vacuumizing device is controlled to be in a closed state, and due to the fact that pressure difference exists between the first tank body and the external environment, air flow can rapidly flow in the pipeline under the action of the pressure difference, and therefore the pipeline between the first tank body and the communicating branch is cleaned. Further, when the communication branch is controlled to be communicated with the first tank body, the first tank body can be controlled to be communicated with the second tank body, so that pipelines between the first tank body and the second tank body and between the second tank body and the communication branch can be cleaned under the action of pressure difference.

After the vacuumizing operation is completed, the control device controls the fifth control valve 95 and the first control valve 91 to be closed, the stirring operation is performed in the first stirring tank 1, and because the vacuum environment is formed in the first stirring tank 1, bubbles are not easily generated in the first stirring tank 1 during the stirring process of materials, so that the reliability of battery processing production can be effectively guaranteed.
When the stirring process of the first stirring tank 1 is completed, the second stirring tank 2 and the third stirring tank 3 need to continue the stirring operation. At this time, the first stirring tank 1 needs to be evacuated, and the second stirring tank 2 and the third stirring tank 3 need to be evacuated after the completion of the loading. The control device firstly controls the first control valve 91, the second control valve 92 and the third control valve 93 to be opened, so that the first sub branch 81, the second sub branch 82 and the third sub branch 83 are communicated with the main pipeline 7, and then the interiors of the first stirring tank 1, the second stirring tank 2 and the third stirring tank 3 are communicated, so that the pressure in the first stirring tank 1, the second stirring tank 2 and the third stirring tank 3 is balanced, and the three stirring tanks are all in a low-pressure state, at this time, the pressure in the first stirring tank 1 needing to be vacuumized can be increased to 50% -70% of the atmospheric pressure from the vacuum state. Of course, it is understood that the control device may also control the first control valve 91 and the second control valve 92 to open first to balance the pressures in the first stirring tank 1 and the second stirring tank 2, control the third control valve 93 to open after the pressures are balanced to balance the pressures in the first stirring tank 1, the second stirring tank 2 and the third stirring tank 3, or control the first control valve 91 and the second control valve 92 to open first to balance the pressures in the first stirring tank 1 and the second stirring tank 2, and control the second control valve 92 to close after the pressures are balanced to open the third control valve 93 to balance the pressures in the first stirring tank 1 and the third stirring tank 3.

The first agitation tank 1 may be separately subjected to a vacuum discharge operation.
When dust cleaning needs to be performed on the pipeline of the stirring device, for example, the first sub-branch 81 and the third sub-branch 83 corresponding to the first stirring tank 1 and the third stirring tank 3 need to be cleaned, assuming that the first stirring tank 1 is in a vacuum state. The control device firstly controls the first control valve 91 and the third control valve 93 to be opened, controls the second control valve 92, the fourth control valve 94 and the fifth control valve 95 to be closed, and then controls the sixth control valve 96 to be opened after the pressures in the first stirring tank 1 and the third stirring tank 3 are balanced.
