Ceramsite sand preheating discharging device and discharging preheating method

Abstract

The invention discloses a ceramsite sand preheating and discharging device which comprises a discharging device, a preheating device is arranged at the bottom of the discharging device, a rotary kiln is arranged at the bottom of the preheating device, the preheating device comprises a mixing device, and a heat preservation device is arranged outside the mixing device. According to the ceramsite sand preheating and discharging device and the discharging and preheating method, the preheating device and the discharging device are arranged to control the feeding amount of materials, hot air in the rotary kiln enters the mixing device, the heat preservation device delays the heat leakage speed of equipment through heat circulation and water circulation, and under the action of the stirring device, the falling speed of the materials is deferred; the stirring frequency is increased, the preheating time of the materials is prolonged, the materials are preheated by utilizing redundant heat generated during working of the rotary kiln, the heat utilization rate is increased, the energy consumption is reduced, and the problems that traditional preheating equipment is low in heat utilization rate and high in energy consumption and does not conform to the green and environment-friendly production concept are solved.

Description

technical field [0001] The invention relates to the technical field of ceramsite production, in particular to a ceramsite sand preheating and blanking device and a blanking preheating method. Background technique [0002] Ceramsite, as the name suggests, is ceramic particles. Most of the appearance characteristics of ceramsite are round or elliptical spheres, but there are also some gravel-like ceramsites that are not round or elliptical spheres, but irregular gravel. The shape of ceramsite varies from process to process. Its surface is a hard shell, which is pottery or enamel, which has the function of water-proof and air-retaining, and gives ceramsite a higher strength. Ceramsite is generally used to replace crushed stones and pebbles in concrete. [0003] In the production process of ceramsite, because it needs to be calcined at high temperature, in order to avoid cracking caused by a sharp rise in the temperature of ceramsite, it is necessary to perform preheating trea...
