Dry acetylene carbide slag treatment equipment for acetylene recycling

Abstract

The invention discloses dry acetylene carbide slag treatment equipment for acetylene recycling, and belongs to the technical field of carbide slag treatment. The equipment comprises a jaw crusher anda screening box, the jaw crusher comprises a flywheel, a receiving hopper is fixed at a bottom outlet of the jaw crusher, the screening box is positioned below the bottom outlet of the jaw crusher, afeeding port is formed in the top of the screening box, the receiving hopper is fixed to the top of the feeding port, a slag discharging port is formed in one side of the screening box, a dischargingport is formed in the bottom of the screening box, connecting grooves are formed in the inner walls of the two sides of the screening box, a screening frame is arranged in the screening box, and a screen is fixed in the screening frame. The equipment is reasonable in structure, ingenious in design and simple to operate, crushed carbide slags can be screened, the uniformity of the particle size ofthe crushed carbide slags is guaranteed, so that subsequent processing and use of the carbide slags are facilitated, and the equipment is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of carbide slag treatment, in particular, the invention relates to dry-process acetylene carbide slag treatment equipment for recycling acetylene. Background technique [0002] Calcium carbide slag is the waste residue with calcium hydroxide as the main component after the hydrolysis of calcium carbide to obtain acetylene gas. Acetylene is one of the important raw materials in the basic organic synthesis industry. The process of producing acetylene with calcium carbide as raw material and adding water is simple and mature. large proportion. Adding water to 1T of calcium carbide can generate more than 300 kg of acetylene gas, and at the same time generate 10T of industrial waste liquid with a solid content of about 12%, commonly known as calcium carbide slurry. The use of calcium carbide slag can replace limestone to make cement, produce quicklime as a raw material for calcium carbide, produce chemical produ...

AI Technical Summary

Problems solved by technology

[0003] There will be many large pieces of calcium carbide slag in the generated carbide slag, which can be used after crushing. A crushing device is needed to crush the raw materials of large calcium carbide slag. In the prior art, a crusher is generally used to crush the carbide slag. However, the existing crushers only have the function of crushing, but they cannot screen the crushed carbide slag, which will easily lead to uneven particle size of the carbide slag after dissection, which will affect the subsequent production.
