Link plate type high-temperature automatic constant weight feeder

Abstract

The invention provides a link plate type high-temperature automatic constant weight feeder, comprising a conveying control metering device arranged below a feeding hopper, a cleaning device arranged below the conveying control metering device, and a program control system. The link plate type high-temperature automatic constant weight feeder is mainly and technically characterized in that the conveying control metering device is a single-faced board turning link plate driven by a chain wheel; a link plate conveying belt is coated on the single-faced board turning link plate; a sensor device is further arranged below the conveying control metering device; the sensor device is provided with a plurality of flexible guide rails below the link plate conveying belt; a plurality of supporting guide rails are connected with the flexible guide rails at both sides; and sensors are respectively connected with the supporting guide rails. With the adoption of the link plate type high-temperature automatic constant weight feeder provided by the invention, the metering precision is influenced by the high temperature of a material in conveying and metering processes, and the influence on the precision, caused by factors of high temperature, belt stretching and the like when a high-temperature material is metered, are avoided, so that the metering precision is improved from 3% to 1%, and the cement quality can be effectively ensured.

Description

technical field [0001] The invention relates to production equipment in high-temperature environments such as cement and steel, in particular to special equipment for conveying high-temperature material ingredients and automatic metering during the production process. Background technique [0002] At present, most enterprises in the cement industry have various factors such as increasing production volume, resulting in high clinker temperature (50% of enterprises are at about 90°C, 30% of enterprises are at 120°C, 20% of enterprises are at 150°C, and some even reach 200°C), the conventional metering feeder is generally used at 150°C, and the high-temperature tape with a temperature resistance of 200°C has a service life of less than three months; especially in summer, it is even necessary to replace 1-3 belts a day, which is costly and The maintenance intensity is high and the production efficiency is low; more importantly, due to thermal expansion and cold contraction, the ...
