Structure and method for preventing blockage of vertical mill feeding system

Abstract

The invention discloses an anti-blocking structure and method for a vertical mill feeding system, and relates to the field of cement raw material grinding, the anti-blocking structure comprises a vertical mill system, the vertical mill system comprises a small bin box body, a chain plate scale and a mill feeding scraper-trough conveyer, and the anti-blocking structure further comprises an air heating main pipeline, and an air outlet of the air heating main pipeline is connected with a hot air induced pipe; a three-way valve is arranged at one end of the hot air inducing pipe, an air outlet of the three-way valve is respectively connected with a first air inducing pipe and a second air inducing pipe, the first air inducing pipe is communicated with the bottom of the small bin box body, and the second air inducing pipe is communicated with a chain plate scale; the air outlet pipe is arranged on the back face of the small bin box body, the end, penetrating out of the small bin box body, of the air outlet pipe is connected with the mill inlet scraper-trough conveyer, the pressure at the mill inlet pipeline and the pressure difference at the mill inlet scraper-trough conveyer in the mill are utilized, the small sealed bin is of a box body type through structure, and circulating hot air is formed. And the circulating hot air dries the materials entering the warehouse, the scale body and the grinding scraper-trough conveyer.

Description

technical field [0001] The invention relates to the field of cement raw meal grinding, in particular to a structure and method for preventing clogging of a vertical mill into a grinding system. Background technique [0002] Cement clinker is a semi-finished product obtained by using limestone, clay and iron raw materials as the main raw materials, which are prepared into raw materials in appropriate proportions, burned until partially or completely melted, and then cooled; For the grinding system, in order to effectively solve the air leakage problem of the raw meal vertical grinding system, most cement clinker production lines have renovated the grinding part, and adopted a sealed small warehouse and a sealed chain plate scale, and the air leakage problem has been effectively solved. [0003] Due to factors such as weather, high moisture content of incoming materials, and the use of viscous materials for ingredients, after the equipment has been running for a long time, the...
