Finery for recycling and processing waste and old lead acid accumulator

Abstract

The invention discloses a finery furnace used for recycling and treating a waste lead acid battery, which comprises a furnace body, an operating platform, a flue, a smelting boiler, and a lead outlet pipe. An empty cavity is arranged in the middle of the furnace body, the operating platform is arranged at the top part of the furnace body, the smelting boiler is arranged on the lower side of the operating platform, the smelting boiler is arranged inside the empty cavity of the furnace body, the flue is arrange at the upper part of the furnace body, the flue is communicated with the empty cavity of the furnace body, the lead outlet pipe is connected at the lower part of the smelting boiler, the invention also comprises a gas pipe, one end of the gas pipe is arranged at the middle and lower part position of the furnace body, and is communicated with the empty cavity of the furnace body, and the other end thereof is connected to a gas generating furnace. The gas generating furnace is adopted in the invention to perform gas burning heating of the finery furnace through the gas pipe, the defaults that the dust is too much and the temperature is not enough when the worker adds and pokes the coal as the coal burns are overcome, the invention has the advantages that the dust is less, the heating is fast, the melting time is short, the melting is sufficient, and the invention has no harm to the human body and the environment. The thermal protective coating is arranged outside the furnace body, to reduce the heat loss in the furnace body, and the energy is economized.

Description

【Technical field】 [0001] The invention relates to the field of lead-acid batteries, in particular to a refining furnace for recycling and treating solid waste in waste lead-acid batteries. 【Background technique】 [0002] Lead-acid batteries are used in a wide variety of applications to power a wide variety of products. At present, electric bicycles that are vigorously promoted as smoke-free vehicles basically use lead-acid batteries to provide walking power. However, lead-acid batteries are prone to cause "secondary pollution" but the development of this new type of means of transportation has been criticized. [0003] Lead-acid batteries are composed of positive and negative plates, separators, shells, electrolytes and wiring pile heads, etc. The chemical reaction of the discharge depends on the positive plate active material (lead Lead) is carried out under the action of electrolyte (dilute sulfuric acid solution), wherein the grid of the pole plate is made of lead-antim...

AI Technical Summary

Problems solved by technology

[0007] The current refining furnaces all use the method of manual coal-fueling operation with a combustion furnace in front of the furnace for combustion and heating. There are problems such as too much coal dust caused by workers adding coal, the temperature is not in place, the combustion is not sufficient, the lead recovery rate is low, and the melting time is long. , causing harm to the human body and the environment
