Description

A new drip rolling acid device for smearing green plates

technical field

The patent of the present invention relates to the field of lead-acid storage battery manufacturing, in particular to a novel drip rolling acid device for smearing green plates.

Background technique

During the manufacturing process of lead-acid batteries, the grid is filled with lead paste by a plate coating machine to form the prototype of the raw plate. At this time, the lead paste on the surface of the grid is soft and uneven, and it needs to be rolled to make the surface smooth to ensure the grid and Paste bonded well. During the rolling process of the raw electrode plate, anti-adhesion measures need to be taken to prevent the lead paste from adhering to the rolling roller. The surface of the rolling roller will not stick to the lead plaster due to the scouring of the acid solution. However, the existing method has the following defects: in order to ensure that the surface of the rolling roller does not adhere to the lead paste, a large flow rate needs to be maintained during spraying, which consumes a lot of dilute sulfuric acid solution; in the case of dilute sulfuric acid solution spraying rich liquid Rolling down, the dilute sulfuric acid will overflow from the surface of the raw plate before rolling to the surface of the post-rolling plate, resulting in uneven acid solution on the surface of the green plate, and the acid solution on the surface of the green plate after rolling is relatively thick. Many, when the subsequent surface is dry, the temperature of the kiln is high, which increases the energy consumption in the production process; when spraying and scouring, part of the lead paste on the surface of the raw plate will be washed away with the acid liquid, and the lost lead paste and acid liquid It causes waste and increases the production cost. If it is recycled, it will cause secondary pollution. While increasing the environmental protection treatment fee, it also needs to occupy labor and equipment.

Contents of the invention

The technical problem to be solved by the present invention is to provide a new type of drip rolling acid device for smearing green plates. The acid solution is dripped on the pressure roller wrapped with acid-resistant cloth to carry out acid rolling on the green plates. Sour evenly.

The present invention is realized through the following technical solutions:

A new type of drip rolling acid device for smearing green plates, including relatively rotating press rollers on the smearing machine for pressing the lead paste, and a number of droppers are arranged above the press rollers, and each dropper is connected to the suction The liquid pipe is connected, the liquid inlet of the suction pipe is connected with the liquid storage container, and the outer peripheral surface of the pressure roller is covered with at least one layer of acid-resistant cloth.

A further improvement of the present invention is that the dropper is composed of a hose and a hard tube, one end of the hose is correspondingly socketed with several openings on the outer wall of the suction pipe, and the other end is socketed and fixed with the hard tube.

A further improvement of the present invention is that a solenoid valve is provided on the liquid suction pipe, the solenoid valve is electrically connected to the switch controller of the smear machine, and the solenoid valve is located upstream of the branch port of the liquid suction pipe.

A further improvement of the present invention is that the hard tube is vertically fixed on the cross arm above the pressure roller, and the cross arm is fixed on the frame on both sides of the pressure roller,

A further improvement solution of the present invention is that the flexible pipe is sleeved on the upper port of the hard pipe, and the hard pipe is provided with a throttle valve.

Compared with the prior art, the present invention has the following advantages:

1. The acid inlet electromagnetic valve of the present invention is linked with the control switch of the raw plate smear machine, without the need for staff to individually control the switch. When the smear machine is working, the solenoid valve opens the acid liquid and enters the pipeline to drip acid. When the smear machine stops, the acid Liquid will not flow down.

2. The present invention adopts a plurality of acid liquid distribution branch pipes to communicate with the suction pipe and the position can be adjusted to ensure that each part of the acid-resistant cloth absorbs acid evenly and then ensures the uniformity of rolling acid; the throttle valve on each distribution branch pipe controls the speed of acid dripping , the opening and closing and flow rate of each branch can be individually controlled according to the actual needs in production.

3. The acid solution used in the present invention is completely absorbed in the acid-resistant cloth, so there is no waste of acid solution. When the acid is rolled, the acid solution has no impact on the lead plaster, which will not cause the lead plaster to fall off and will not cause waste of the lead plaster. It not only reduces the production cost, but also reduces the pollution of lead mud and acid liquid, and also avoids the expenditure of various expenses in the subsequent recycling process.

4. The acid liquid on the surface of the raw plate after rolling acid is moderate, and the kiln temperature can be dried without too high when the surface is dry, reducing energy consumption.

detailed description

As shown in Figure 1, a new type of drip rolling acid device for smearing raw plates includes a relatively rotating press roller 1 for pressing the lead paste on the smear machine, and several droppers 2 are arranged on the top of the press roller 1, each Each dropper 2 is connected with the suction pipe 3, the liquid inlet of the suction pipe 3 is connected with the liquid storage container, and the outer peripheral surface of the pressure roller 1 is covered with at least one layer of acid-resistant cloth 4. During operation, the liquid suction pipe 3 sucks the acid liquid into the pipe from the liquid storage container (in this embodiment, the liquid storage container is placed on the top of the liquid suction pipe and the acid is hydraulically entered in the liquid suction pipe by pressure difference, and a pump can also be used. extract the acid solution), and then drop it through the dropper 2, and the dripped acid solution falls on the acid-resistant cloth 4 on the pressure roller 1. With the rotation of the pressure roller 1, the entire acid-resistant cloth absorbs the acid solution, and the raw electrode plate is released from the pressure roller Just pass through in the middle and just can roll acid on its surface, the concentration of the acid solution used in the present embodiment is slightly higher than the concentration of dilute sulfuric acid used in the existing spraying.
