High-temperature material sucking and discharging truck

Abstract

The invention provides a high-temperature material sucking and discharging truck for sucking high-temperature materials by negative pressure and discharging the high-temperature materials by positive pressure. The high-temperature material sucking and discharging truck comprises a high temperature resistant truck chassis, wherein a vacuum pump and a material tank are mounted on the truck chassis; the material tank is connected with an air compressor; a material sucking hole and a tail gate discharging device are mounted at the bottom of the material tank; an air filtering device is mounted in the material tank, fixed at the material sucking hole at the bottom of the material tank, sealed with the material tank and connected with a fine filtering and dust removal chamber outside the material tank through an air pipeline; the fine filtering and dust removal chamber is connected with a metal filter through the air pipeline; the metal filter is connected with a silencer and the vacuum pump through the air pipeline; the air filtering device adopts a sheet-shaped porous ceramic filter; and a filter pipe is also mounted in the fine filtering and dust removal chamber and adopts a tubular porous ceramic filter. According to the high-temperature material sucking and discharging truck, the high-temperature deformation of the filter and the pipeline can be prevented for avoiding the adhesion phenomenon, and the materials can be sucked by the negative pressure and discharged by the positive pressure.

Description

technical field [0001] The invention relates to a high-temperature-resistant material suction and discharge vehicle, in particular to a high-temperature material suction and discharge vehicle for negative-pressure suction and positive-pressure discharge of high-temperature-resistant materials. Background technique [0002] At present, pneumatic suction and discharge vehicles are widely used in steel, thermal power generation and other industries. It collects dust materials at room temperature from containers or scattered ground with vacuum and negative pressure, and discharges the collected materials to other containers through the compressed air generated by the on-board air compressor. In order to realize the long-distance transportation and reuse of dust. However, due to the temperature of dust removal in iron-making and steel-making plants reaching more than 100°C, the temperature of sintering ash in steel-making plants can sometimes reach 600°C, and general suction and ...

AI Technical Summary

Problems solved by technology

[0004] (1) During the working process, the filter layer of the air filter device of the suction and discharge vehicle is deformed and melted, so that the vacuum pump cannot effectively extract the air in the material tank, and cannot form enough negative pressure to complete the suction function;

[0005] (2) The service life of conventional high-temperature cloth bags is relatively short, and it is easy to adhere to the skeleton at high temperatures, making the filter bags difficult to replace and repair;

[0006] (3) The high temperature resistance of the suction pipe is insufficient
