Title:
MANUFACTURE OF LEAD POWDER WITH BULLTONGUE TYPE LEAD POWDER MANUFACTURING MACHINE
Document Type and Number:
Japanese Patent JPH03202405
Kind Code:
A
Abstract:

PURPOSE: To manufacture fine lead powder improving battery performance by automatically controlling each of lad supplying rate, air exhaust rate and water supplying rate at the time of manufacturing lead powder in bulltongue type lead powder manufacturing machine.

CONSTITUTION: By always supplying molten lead 2 into a bulltongue pot 1, this is rotated and stirred with a paddle 3 and oxidized by causing the air to flow into the put 1 with an exhauster 4 and pulverized to form the lead powder 5, and the water is poured from a water pouring hole 7 properly to prevent raising of temp. and also formation of the lead powder is accelerated. Then, PID control (assembly of proportional action P, integral action I and derivative action D) is applied to paddle load current data attenuated by using a converter, and the lead supplying rate is automatically controlled with this value. Further, after attenuating this by using the converter, the PID control is applied to air exhausting rate data subjected to extraction of square root and the air exhausting rate is automatically controlled with this value, and the PID control is applied to the temp. data in the bulltongue pot, and the water suppling rate is automatically controlled with this value. By this method, the lead powder 5 exhibiting the most excellent performance as the lead battery is obtd. and the continuously stable operation of the lead powder manufacturing machine can be executed.
