Embodiment Construction

[0012] General lead-acid batteries are composed of plastic or hard rubber, lead, and sulfuric acid electrolyte. The battery tank 1, cover 2, and separator 3 are made of plastic or hard rubber, the pole plate 4, terminal 5, and bus bar 6 are made of lead, and the sulfuric acid electrolyte 7 is paste.

[0013] A method for recycling waste lead storage batteries, it comprises the following steps:

[0014] 1. Send the recovered waste lead-acid batteries to the drying room for drying treatment. According to the working principle of the lead-acid battery, water will be generated during the discharge process, and the drying here is convenient to separate the waste lead powder from the plastic or hard rubber particles in the subsequent crushing and screening process.

[0015] 2. Put the dried waste lead-acid batteries into the crusher for crushing, and at the same time, send the crushed materials to the screening machine to select the waste lead powder, and then put them in the desul...

Abstract

The invention discloses a method for recycling a waste lead storage battery. The method comprises the following steps of 1, feeding the recovered waste storage battery into a drying chamber to be dried so as to evaporate the moisture inside the lead storage battery; 2, placing the dried waste lead storage battery into a smasher to be smashed, simultaneously sending the smashed articles into a screening machine to select the waste lead powder, and then placing the waste lead powder into a desulphurization pond to be desulphurized; and 3, sending the residual particles into the smasher to be smashed, sending the smashed articles into the screening machine, and recovering the selected plastic particles and the hard rubber particles respectively into a plastic collecting area and a hard rubber collecting area. The desulphurization agent used in the desulphurization pond is limestone-gypsum, a wet desulphurization method is used, the desulphurization product is gypsum which can be used as a building material, and the lead is also replaced. By adopting the method, the problem that the waste lead storage battery pollutes the environment can be solved, and the resource waste can be reduced.

Description

technical field [0001] The invention relates to a method for recycling waste lead storage batteries. Background technique [0002] With the advancement of science and technology and the development of electrical products, people's demand for lead-acid batteries is increasing, but at the same time, the use of lead-acid batteries is disposable, the cost is high, and the environmental pollution problems caused by waste lead-acid batteries are becoming more and more popular. Therefore, it is necessary to recycle and reuse waste batteries. Contents of the invention [0003] The object of the present invention is to provide a method for recycling waste lead storage batteries. The present invention is to classify and recycle the recovered waste storage batteries after some treatment. General lead-acid batteries are composed of plastic or hard rubber, lead, and sulfuric acid electrolyte. [0004] Concrete scheme flow process of the present invention is: [0005] Step 1: Send th...
