Belt casting machine for preparing lead belts for battery grids

Abstract

The invention discloses a belt casting machine of a lead belt for preparation of a storage battery grid. A cooling medium inlet is formed in one end of an end cover of a rotating casting mold, a cooling medium outlet is formed in the other end of the end cover of the rotating casting mold, and a casting groove is formed in the outer circle of the end cover. The casting groove and the outer cambered surface of a fixed mold form a casting mold cavity. The fixed mold is a metal block with the outer cambered surface, and a fixed mold loading device abuts against the other end of the fixed mold. A lead supply tube and a heating tube are mounted on the side wall of the fixed mold, and a cooling medium through hole and an inert gas hole are further formed. A lead belt guide wheel A and a lead belt guiding device are arranged at the lower end of the rotating casting mold. A lead belt cooling device is arranged between the belt guide wheel and the lead belt guiding device. A lead inlet of the lead supply tube is connected with a lead conveying pipe, a lead outlet passes through a small hole reflux device and then is connected with a lead returning tube, and a lead outlet hole is formed in the middle wall. The lead conveying pipe is connected with a lead smelting furnace through a lead pump. A control system controls the lead injection flow to be matched with the rotating speed of the rotating casting mold and the cooling speed of lead liquid. The belt casting machine of the lead belt for preparation of the storage battery grid is low in production cost, high in working efficiency, small in lead fume pollution, stable in performance, good in sealing effect, and capable of avoiding generation of lead oxide and obviously improving lead belt quality.

Description

technical field [0001] The invention belongs to the technical field of heavy metal casting and rolling, and relates to a continuous belt casting machine for preparing lead belts for storage battery dragnets or stamped grids. Background technique [0002] At present, the vast majority of battery manufacturers in China adopt the traditional gravity casting grid production technology. The lead liquid temperature used in the casting machine used in this technology is high, and the non-closed casting not only has high energy consumption, serious lead fume pollution, but also low production efficiency and high labor intensity for workers. Although some battery equipment manufacturers began to try the development of continuous lead belt casting machines after the introduction of expanded mesh or stamped grid production technology, the products developed are generally directly applied to cast steel and aluminum casting equipment; horizontal drawing casting and horizontal casting are...

AI Technical Summary

Problems solved by technology

The horizontal flow increases the contact between the lead liquid and the air, which causes the inclusion of lead oxide inside the lead belt and affects the quality of the lead belt

[0006] Both the above-mentioned horizontal twin-roller casting and the wheel-type belt casting machine have the following disadvantages: since the liquid lead enters the casting cavity by itself flowing from high to low, the requirement for the fluidity of the lead liquid is high, that is, the temperature of the lead liquid is required High; the lead liquid is not sealed during the transportation process, and the lead liquid not only has a temperature loss during the transportation process, but also easily forms lead oxide; therefore, the temperature of the lead liquid in the lead melting furnace is required to be very high, which not only consumes high energy, but also causes lead smoke pollution serious
