Abstract

The invention relates to an automatic alarm and protection device for a tank truck pneumatic conveying system, which includes a flux-sealed mine bin, a mine bin weighing system, a remote PLC mine bin control system, a material level alarm display, a flux conveying pipeline, a tank truck and a compressed air supply system , it is characterized in that: the weighing system of the ore bin is composed of a weighing level gauge arranged on the support of the flux-sealed ore bin platform, and one end of the communication bus is connected to the weighing level gauge, and the other end is connected to the remote PLC The material level alarm display of the mine control system is composed of a manual shut-off valve and an electric shut-off valve on the tank truck compressed air branch pipe and the flux conveying compressed air branch pipe respectively; the remote PLC mine bin control system passes The communication bus is respectively connected with the electric shut-off valve on the compressed air branch pipeline of the tanker and the electric shut-off valve on the compressed air branch pipeline for flux delivery. The invention has the advantages of effectively ensuring the control of the storage capacity of the flux-sealed ore and the safe production of sintering.

Description

Technical field [0001] The invention belongs to the technical field of flux tank car pneumatic conveying in the metallurgical sintering industry, and particularly relates to an automatic alarm and protection device for a tank car pneumatic conveying system. Background technique [0002] At present, in the metallurgical sintering industry, quicklime, light-burned dolomite and other fluxes are purchased outside the factory, and the finished products are transported into the factory by tankers, and transported to the flux-sealed mine bin in the batching room by means of compressed air blowing, and a cloth bag dust removal device is installed on the top of the bin to collect dust And pressure relief, the storage volume of the flux-sealed ore is measured with a weighing level gauge. [0003] Because the sintering production operation management has strict requirements on the reserves of the ore tank, the phenomenon of emptying and overloading of the ore tank is prevented in the sinterin...
