Abstract

The invention discloses a control method of a powder conveying system, and the powder conveying system comprises a positive pressure sending tank, a powder stirrer and a powder conveying pipe. Wherein the positive pressure sending tank is provided with a compressed air inlet so that the space in the tank can have first pressure P1, and the powder stirrer is provided with a feeding port used for being communicated with a powder conveying pipe and an extraction opening communicated with an external negative pressure pipeline so that the powder stirrer can have second pressure P2; the interior of the powder conveying pipe has third pressure P3; the positive pressure sending tank has a first volume V1, the powder stirrer has a second volume V2, and the powder conveying pipe has a third volume V3; the control method comprises the step that the first pressure P1, the second pressure P2 and the third pressure P3 meet the condition that P1 > = P3 > = P2. The control method for the powder conveying system has the beneficial effect that the pressure is dynamically adjusted, so that positive-pressure powder spraying or equipment damage is prevented.

Description

technical field [0001] The present application relates to the field of powder conveying, in particular, to a control method of a powder conveying system. Background technique [0002] At present, the original process of lithium electrode plate workshop mostly adopts gravity blanking of powder, and the layout of powder equipment and mixer will require a high height of the factory building. At present, some lithium battery manufacturers are involved in the addition and transformation of equipment, and the original mixer plant has limited space. If the transformation of the factory building is heavy workload, high cost, and difficult to implement, so the powder is sent to the mixer by positive pressure delivery. However, during the commissioning, it was found that due to the small size of the original design of the exhaust valve and breathing mask of the mixer, the exhaust was not timely, resulting in overpressure in the mixer container, and powder was sprayed at the joints of...
