Open-wind belt material-type alumina crust block crushing production line device

Abstract

The invention relates to an open-wind belt material-type alumina crust block crushing production line device which comprises a first electric butterfly valve, a crusher, a first iron remover, a conveyer, a raw material bin, a gate valve, a vibratory feeder, a second electric butterfly valve, a pulverizer, a first pressure transmitter, a coarse powder separator, a second pressure transmitter, a temperature transmitter, a dust collector, an electric adjusting air door, a blower fan, a second iron remover, a third pressure transmitter, a finished product bin, and an electric gate valve. The invention realizes a material feeding particle size of not more than 300mm and a material discharge particle size of not more than 1 mm by one-stage crushing processing of the alumina crust blocks in the production line; the crushing production line device of the invention has less crushing equipment and conveying equipment by 2-3 than current multi-stage crushing devices, but reaches the material discharge particle size that is reached by 2 to 3-stage crushing in the prior art, which improves the production efficiency, and reduces consumption. Meanwhile, the device of the invention is simple in structure, easy to reconstruct, simple in adjustment, convenient for use, energy-saving, high in efficiency, safe, and environment friendly.

Description

technical field [0001] The invention relates to a crushing production line device, in particular to an open wind belt material type alumina crust block crushing production line device. Background technique [0002] In recent years, the electrolytic aluminum industry has developed rapidly. Statistics show that since 2001, the domestic demand for electrolytic aluminum has grown at a rate of 1 million tons per year; by the end of 2003, the production capacity of electrolytic aluminum had reached 8.34 million tons; by 2008, electrolytic aluminum The production capacity has reached 12.5 million tons. With the rapid growth of electrolytic aluminum production in my country, the amount of alumina crusts left over by electrolytic aluminum enterprises in production has also increased. However, the domestic research and development status of the crushing process of alumina crust blocks is limited to the rectification and improvement of a single device. The overall equipment and the m...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects of the existing processing technology of alumina crust blocks, and provide a new structure of open air belt material type alumina crust block crushing production line device, the technical problem to be solved is Make it through the first-stage crushing process of the production line, so that the input particle size is ≤300mm, and the output particle size is ≤1mm. Compared with the existing multi-stage crushing, 2-3 crushing equipment and conveying equipment are used less. However, it has reached the standard discharge particle size that can only be achieved through 2-3 stages of crushing in the past, which improves production efficiency and reduces consumption. At the same time, by setting electric butterfly valves, electric dampers, pressure transmitters and temperature sensors on the production line, the In order to adjust the production line, and monitor the pipeline pressure and temperature of the production line in time, so as to know the operation of the production line at any time, ensure that the faults in the production line operation can be found at any time, and deal with them in time, reducing the blindness of workers' work It reduces the labor intensity of workers, saves time and production costs; in addition, by setting up dust collection pipes in multiple places in the production line, it can better ensure the on-site use environment, meet the requirements of national environmental protection, and improve the work of workers environment, ideal for practical
