Acid liquid collection device for polar plate production and operation method of acid liquid collection device

Abstract

The invention discloses an acid liquid collection device for polar plate production. The acid liquid collection device comprises an acid liquid collection mechanism, a preliminary sedimentation mechanism, a filter mechanism and an acid liquid storage mechanism, the acid liquid collection mechanism comprises a collection tank and a guide pipe, the preliminary sedimentation mechanism comprises a sedimentation pond, a mud discharge pipe, a mud discharge valve, a collection box and a first magnetic valve, the filter mechanism comprises a liquid inlet pipe, an acid pumping pump, a filter valve, anacid conveying pipe, a mud discharge pipe and a flowmeter, and the acid liquid storage mechanism comprises an acid liquid storage tank, a third liquid inlet, a second liquid level sensor, an acid outlet and a liquid drain valve. The invention further discloses an operation method of the device. The acid liquid sediments large-particle lead plaster through the sedimentation pond, the sedimented acid liquid is pumped into the filter valve by using the acid pumping pump, small-particle lead plaster is filtered by acid liquid through the filter valve, and is collected in the acid liquid storage tank along the acid conveying pipe, the secondliquid level sensor is arranged in the acid liquid storage tank, and the effect of monitoring the acid liquid reserve can be played. The whole device has high automation degree and high acid liquid collection efficiency.

Description

technical field [0001] The invention belongs to the technical field of lead-acid battery production, and in particular relates to an acid liquid collecting device for pole plate production and an operating method thereof. Background technique [0002] At present, during the coating production process of lead-acid battery plates, most manufacturers use acid leaching to form a layer of lead sulfate on the surface of the plates. The hardness of lead sulfate is greater than that of lead paste. After drying, the plates will not In addition, the formation of lead sulfate with a certain hardness on the surface of the plate also protects the plate from powder removal and prolongs the service life of the plate. However, during the acid leaching process of the plate, a large amount of leaching acid residue and acid leaching will be produced. For the excess leaching and acid residue generated by leaching acid, most manufacturers currently use centralized collection and put them in haza...

Problems solved by technology

[0004] The invention uses a filter screen and a filter cloth to filter the acid liquid. During the acid liquid filtration process, the filter screen and filter cloth need to be cleaned and replaced manually, which affects the overall collection efficiency and requires more labor and materials. , the use of sedimentation tanks requires a larger site and lower processing efficiency, which cannot meet the needs of enterprises for energy saving and emission reduction
