Lead liquid dosing device and plate-casting machine

Abstract

The invention discloses a dosing device for liquid lead, which comprises a shell, a valve core, a valve stem and a quantitative cylinder. The shell is hollow and is provided with a lead inlet and a lead outlet; the valve core is positioned at one end inside the shell, a liquid lead channel for connecting the lead inlet and the lead outlet is arranged on the valve core. The valve stem is arranged at the other end inside the shell. One end of the valve stem is provided with a conical head for closing the liquid lead channel. The quantitative cylinder is connected at the other end of the valve stem. As the quantitative cylinder is adopted to control the valve stem to close the lead liquid channel of the valve core, the dosing device for the liquid lead by adopting the technical scheme of the invention has the advantages of simple structure, low cost and reliable working. As the using of the dosing device for the liquid lead, a casting plate device thereof has the advantages of more steady performance, more accurate dosing for the liquid lead, less waste and low cost. As the dosing device is arranged between a lead pipe and a lead ladle far away from a scorching lead furnace, the service life is longer and the maintenance is more convenient.

Description

technical field [0001] The invention relates to equipment for casting storage battery grids, in particular to a liquid lead quantitative device and a casting machine using the liquid lead quantitative device, belonging to the field of lead-acid storage battery manufacturing. Background technique [0002] General lead-acid battery, its main component - plate, is composed of active material filled in the mesh of the grid, the quality of the grid is crucial to the performance of the plate; and the grid is generally produced by a casting machine Yes, the technical level of the casting machine is a key factor in the production of high-quality lead-acid batteries.

Problems solved by technology

Due to the high temperature in the lead furnace, it is not conducive to maintenance

Generally, it is necessary to stop the machine, then pull the lead pump and lead valve out of the lead furnace, and then repair them after they cool down, which will inevitably affect the work efficiency.

Moreover, the structure of the existing lead valve is complicated, and the working environment is harsh. If general materials are used, the service life is very short and the maintenance cost is high; if special materials are used, the cost is relatively high.
