Problems solved by technology

According to the traditional acid adding process and the actual situation of the equipment, under different ambient temperatures, the addition of the paste acid needs to manually control the opening degree of the acid valve to control the paste temperature to meet the process requirements. It is not easy to control, and due to the frequent rotation of the acid adding valve, there are occasional loosening during the whole acid adding process, which affects the stable execution of the process

Embodiment 1

[0023] see figure 1 as shown, figure 1 A flow chart of an acid addition method used in the paste process for battery plate manufacturing provided in Embodiment 1 of the present invention includes the following steps:

[0024] Step 101: Install at least two acid adding pipes on the acid tank of the paste mixer, and the flow rate of each acid adding pipe is different from each other. The flow of each acid pipe is controlled by a flow regulating switch.

[0025] Step 102: Divide the ambient temperature of the outside world into several levels, set an acid addition rate corresponding to each temperature level, and then save the data in the processor.

[0026] For example, divide the external ambient temperature into low temperature, normal temperature, high temperature, etc. Specifically, if the external ambient temperature is lower than 0°C, set the acid addition rate to 15ml / s; The speed of acid is set to 10ml / s, if the temperature is higher than 28°C and lower than 42°C, set...

Embodiment 2

[0033] According to the above method, the embodiment of the present invention also discloses an acid adding device, please refer to figure 2 As shown, the acid adding device includes the paste machine acid tank 201, and at least two acid pipes 202 and processor 203, the acid pipe 202 is connected with the paste machine acid tank 201, and the acid solution in the paste machine acid tank 201 The acid adding pipe 202 is input into the paste container, and the flow rate of each acid adding pipe 202 is different from each other, and the on and off of each acid adding pipe 202 is controlled by the processor 203 .

[0034] Specifically, each acid adding pipe 202 is fixed with an electromagnetic valve 204, and the electromagnetic valve 204 is fixed on each acid adding pipe 202 and is connected with the processor 203, and the activation or closing of the electromagnetic valve 204 is controlled by the processor 203, and each The conduction and closure of each acid pipe 202 are controll...

Abstract

The invention discloses an acid adding method used for a paste mixing operation and an acid adding device. The method comprises the steps of: installing at least two acid adding pipes on a paste mixer acid pot, with each acid adding pipe maintained mutually different flow; reading the external ambient temperature, and searching a needed acid adding speed; starting the acid adding pipe that satisfies the acid adding speed and conducting acid adding. The acid adding device comprises a paste mixer acid pot, and additionally at least two acid adding pipes and a processor. The acid adding pipes are in connection with the paste mixer acid pot, within which the acid liquid is conveyed to a paste mixing container through the acid adding pipes. Each acid adding pipe has mutually different flow, and the conduction and closure of each acid adding pipe is controlled by the processor. Compared with prior art, the acid adding method and acid adding device provided in the embodiment of the invention reduces variable factors of manual operation, guarantees acid adding stability and consistency, and guarantees the quality consistency of lead paste, so that the consistency of a battery plate is guaranteed and then the battery quality can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to an acid adding method and device used in the paste mixing process of battery pole plate manufacture. Background technique [0002] Paste mixing is the core process of battery plate manufacturing, and the quality of the lead paste produced directly determines the performance of the battery plate. The addition of the paste acid and the control of the temperature are particularly important. At present, a single acid tube is used to manually control the flow of the paste acid. According to the traditional acid adding process and the actual situation of the equipment, under different ambient temperatures, the addition of the paste acid needs to manually control the opening degree of the acid valve to control the paste temperature to meet the process requirements. It is not easy to control, and due to the frequent rotation of the acid addition valve, occasional loosening...
