Anti-blocking type lightly-calcined magnesium oxide powder feeding buffering bin

Abstract

The invention discloses an anti-blocking type lightly-calcined magnesium oxide powder feeding buffering bin. A bin body is vertically arranged, is of a two-section type structure and comprises a bin body straight section and a bin body tapered section, the bin body straight section is located on the upper portion, the bin body tapered section is located on the lower portion, the top end of the binbody straight section is provided with a mineral powder feeding port, the bottom end of the bin body tapered section is provided with a mineral powder discharging port, and a bar valve is installed at the mineral powder discharging port; anti-sticking material lining plates are laid on the inner surfaces of the bin walls of the bin body straight section and the bin body tapered section and made of polytetrafluoroethylene plates or surface-polished stainless steel plates; the section of the bin body straight section is in a rectangular shape, and the inclination angles of the bin walls of thefour faces of the bin body straight section are each 0 degree; the section of the bin body tapered section is in a trapezoidal shape, the bin walls of the bin body tapered section adopt large inclination angle design, and the inclination angles of the bin walls of the four faces of the bin body tapered section are different; and the axis of the mineral powder feeding port and the axis of the mineral powder discharging port are eccentrically arranged. According to the anti-blocking type lightly-calcined magnesium oxide powder feeding buffering bin, the problems of bin wall material sticking andbin wall material blocking are solved, the problems of powder bin pressing and nonuniform discharging are solved, a calcinator can stably run, and the production efficiency of lightly-calcined magnesium oxide is improved.

Description

technical field [0001] The invention belongs to the technical field of light-burned magnesia powder production, in particular to an anti-blocking type light-burned magnesia powder feeding buffer bin. Background technique [0002] At present, the production process of light-fired magnesia mainly includes various roasting processes such as reverberatory kiln, rotary kiln, multi-layer furnace, suspension furnace, etc. Although these roasting processes are different, they all use the loading buffer bin. [0003] Taking magnesite powder as an example, it is divided into concentrate powder and tailings powder, and has the characteristics of small particle size, high moisture content and high viscosity, which makes the ore powder unsuitable for dispersion. [0004] As the loading buffer bin plays a connecting role in the production process of light-burned magnesia, magnesite powder is sent as a raw material to the feeding buffer bin through the conveying equipment, then enters the ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the present invention provides an anti-blocking light-burned magnesia powder feeding buffer bin, the bin structure design is more reasonable, effectively overcomes the problem of mineral powder sticking to the inner surface of the bin wall, and further It effectively avoids the occurrence of material blocking, and effectively solves the problem of powder pressure bin and uneven discharge, so that the roaster can run stably, improves the production efficiency of light-burned magnesia, and saves manpower and material costs
