Material level detection device for powder silo and material level detection method

Abstract

The invention relates to a material level detection device for a powder silo and a material level detection method. The material level detection device comprises a silo body filled with materials, a detection port, a detection rope and a drop hammer, wherein the detection port is formed in the top of the silo body, a first end of the detection rope extends into the silo body from the detection port, a second end of the detection rope is wound and fixed on the outer side of the silo body, the drop hammer is fixedly arranged at the first end of the detection rope and disposed in the silo body, and a match sealing plug is arranged on the top surface of the drop hammer correspondingly to the detection port and used for plugging the detection port through lifting force of the detection rope. The material level detection device of the powder silo has the advantages that the material level detection device is capable of measuring the height of residual materials in the silo body accurately and then calculating the residual quantity of the materials so as to obtain more precise measurement results than those obtained by traditional human knocking, and does not require that workers climb the silo body for knocking measurement, so that unnecessary potential safety hazards can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a material level detection device and a detection method of a powder silo. Background technique [0002] The silo is a tank used to store cement and other powder materials on the concrete mixing plant. There are usually three to four silos in the concrete mixing plant, the quantity is variable, and the cement, fly ash, mineral powder, expansion agent and other admixtures are stored respectively (all are raw materials for the production of concrete). When the production volume of the mixing station is relatively large, the consumption of powder is very large. Sometimes when the low material level of the silo is alarmed before filling the material, it is likely to delay production and cause great losses to the enterprise. Therefore, it is very necessary for the production of enterprises to know exactly the height of materials through some method. [0003] However, ...
