Bottom discharge method and bottom discharge device for light calcium carbonate calcining furnace

Abstract

The invention provides a bottom discharge method and a bottom discharge device for a light calcium carbonate calcining furnace. A set of vibratory discharge device is arranged below a bottom dischargeport of the calcining furnace, the light calcium carbonate calcined material calcined by the calcining furnace is discharged into the vibratory discharge device through the bottom discharge port of the calcining furnace, the light calcium carbonate calcined material is conveyed onto a calcined material conveying belt by virtue of vibration of the vibratory discharge device, and then, the light calcium carbonate calcined material is conveyed to the next process by the conveying belt. The vibratory discharge device is transversely arranged below a bottom discharge port of the calcining furnace,the feed port of the vibratory discharge device is butted on a movable connection sleeve below the bottom discharge port of the calcining furnace, and the discharge port of the vibratory discharge device is positioned above a calcined material conveying belt; and the charging material discharged from the bottom discharge port of the calcining furnace moves by virtue of vibration of a vibratory pipeline of the vibratory discharge device, moves to the discharge port of the vibratory discharge device, falls onto the calcined material conveying belt in the process of vibration, and is then conveyed to the next process.

Description

technical field [0001] The present invention relates to a light calcium carbonate production process method and device, in particular to a bottom discharge method and device of a light calcium carbonate calciner, which is safer and more efficient. The invention is reliable, saves manpower and material resources, and is convenient for realizing intelligent control, and belongs to the technical field of light calcium carbonate production. Background technique [0002] Light Calcium Carbonate (Light Calcium Carbonate) is also called Precipitated Calcium Carbonate (PCC for short). As a filler with a wide range of uses, light calcium carbonate is widely used in plastics, rubber, papermaking, coatings, and pharmaceutical and food industries. The domestic demand alone is more than 10 million tons per year, and it is an industry with an output value exceeding 10 million tons. A billion-dollar industry. The production of light calcium carbonate is divided according to the carboniza...
