Material level detection device and container of high-temperature solid material

Abstract

The invention relates to the field of chemical engineering and discloses a material level detection device and a container of a high-temperature solid material. The material level detection device comprises a high temperature resistant detection pipe, wherein a gas pipe is disposed in the high temperature resistant detection pipe; a material level detection hole is disposed on the high temperature resistant detection pipe; one end of the gas pipe communicates with a gas source; the other end of the gas pipe communicates with the material level detection hole; gas of the gas source is discharged out from the material level detection hole; and a pressure sensor is disposed on the gas pipe. The material level detection device disclosed by the invention is characterized in that the gas pipe is guided by the high temperature resistant detection pipe; the gas of the gas source is guided to be blown to the material; the material level detection hole is stopped by the material, and the gas pressure in the gas pipe is changed; and thus the material level of the material can be detected. By the technical scheme, the material level detection of the high-temperature solid material can be achieved; the problem in difficult setting of a sensor under a high temperature can be solved; effects of a high-temperature environment on detection results of the sensor can be avoided; the structure is simple; measurement accuracy is high; and applicability is high.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a material level detection device and container for high-temperature solid materials. Background technique [0002] In the field of coal chemical industry, for example, in the process of coal chemical industry such as drying or pyrolysis coal, it is usually necessary to measure the level of high-temperature materials stored in containers. However, none of the current material level gauges can withstand high temperature. Even if the measurement is not in direct contact with the material, it is easily affected by the high temperature environment and the measurement result is inaccurate. Therefore, there is no effective method for measuring the material level of the high temperature material. Contents of the invention [0003] The object of the present invention is to provide a material level detection device for high-temperature solid materials, which uses the change of gas press...
