Phosphorus coal pelletizing equipment for yellow phosphorus production

Abstract

The invention provides phosphorus coal pelletizing equipment for yellow phosphorus production, and belongs to the technical field of chemical engineering. The phosphorus coal pelletizing equipment comprises a machine base, a feeding hopper, an extrusion barrel, a scraping rotary drum and a gear motor. An outer protective cover is fixedly arranged at the lower end of the extrusion barrel, the scraping rotary drum is connected with an output shaft of the speed reducing motor, a shell of the speed reducing motor is fixed on the outer protective cover, the scraping drum is in a cone shape with thesmall-diameter end facing upwards, the scraping drum is sleeved with the outer protective cover, a plurality of scraping plates are evenly arranged on the outer wall face of the scraping drum in thecircumferential direction, the upper end of the outer protective cover extends into the extrusion barrel, a plurality of extrusion holes corresponding to the scraping plates one to one are formed in the outer protective cover, the extrusion holes communicate an inner cavity of the extrusion barrel and an inner cavity of the outer protective cover, an extrusion screw rod located in the extrusion barrel is fixedly arranged at the upper end of the scraping rotary drum, the feeding hopper is fixed to the extrusion barrel, a material groove is formed between every two adjacent scrapers, and the lower end of each material groove is provided with a material receiving plate fixed to the machine base. The phosphorus coal pelletizing equipment has the advantages of being capable of avoiding mutual bonding of blanks in the discharging process and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a phosphorus coal pelletizing equipment for yellow phosphorus production. Background technique [0002] Yellow phosphorus is an important basic industrial raw material, mainly used in the preparation of phosphoric acid, phosphide, phosphate, etc., widely used in fertilizer, feed industry, food processing industry, construction industry, medicine, electronics industry and many other fields. [0003] At present, the main method of industrial production of yellow phosphorus is the electric furnace method, that is, phosphate rock, silica, and coke are placed in an electric furnace according to a certain proportion and particle size, and a reduction reaction occurs at a high temperature of 1400 ° C, and the phosphorus vapor is cooled and washed together with the furnace dust. Finally, the yellow phosphorus product is obtained. Phosphate rock, silica, coke and water are mixed in...

[0003] At present, the main method of industrial production of yellow phosphorus is the electric furnace method, that is, phosphate rock, silica, and coke are placed in an electric furnace according to a certain proportion and particle size, and a reduction reaction occurs at a high temperature of 1400 ° C, and the phosphorus vapor is cooled and washed together with the furnace dust. Finally, the yellow phosphorus product is obtained. Phosphate rock, silica, coke and water are mixed in a certain proportion to make a spherical blank, and then put into an electric furnace for sintering. In order to make the blank into a ball, a certain amount
