Polar plate weighing machine capable of absorbing lead dust

Abstract

The invention discloses a polar plate weighing machine capable of absorbing lead dust. The polar plate weighing machine comprises an outer shell, wherein a weighing region is arranged on the upper part of the outer shell, an electronic scale is arranged in the weighing region, a differentiation region and a stirring region which are communicated with each other are positioned inside the weighing region, a guide pipeline is arranged between the differentiation region and the weighing region, the guide pipeline is provided with an air pump at a position close to the differentiation region, the upper part of the stirring region is provided with a discharge pipeline, a coarse net layer, a first propeller, a thin net layer and a second propeller are sequentially arranged in the differentiationregion along a gas moving direction, and a stirring mechanism is arranged in the stirring region. compared with the prior art, the polar plate weighing machine capable of absorbing lead dust can inject the gas with the lead dust into water, discharges the gas while the lead dust in bubbles is left in water through thinning the bubbles and making the lead dust in contact with water, the problem oflead dust flying can be effectively eradicated when the polar plate is weighed, and the damage to the staff of the lead dust is avoided.

Description

technical field [0001] The invention relates to a pole plate weighing machine capable of absorbing lead dust, which belongs to the technical field of lead-acid storage battery manufacturing. Background technique [0002] In order to ensure the consistency of battery capacity, manufacturers of lead-acid batteries usually produce batteries by weighing the plates and then matching them. Weighing methods are divided into manual weighing and automatic weighing. Manual weighing boards generally use electronic scales to weigh boards, but lead dust is likely to be generated during the weighing process. [0003] Lead dust can enter the human body through the respiratory tract, esophagus and skin, and a part of lead or lead oxide dissolves in the blood, which is difficult to excrete naturally and accumulates in the body. From the urine or blood test, if the lead content in urine is higher than 0.08mg / L without clinical manifestations, it is called lead absorption in medicine, and th...

Problems solved by technology

In order to ensure that the process operates in a local negative pressure environment, a verified suction pressure should be maintained to ensure that lead dust cannot fly in the working environment. However, some existing suction devices have poor filtering functions, and micron-sized lead powder will also A small amount is discharged with the wind, and over time, there will still be lead powder in the workshop
