Intelligent control system and method of bunker network

Abstract

The invention relates to an intelligent control system and method of a bunker network. The system comprises an electronic differential pressure gauge, a mechanical differential pressure gauge, a pinch valve barometric switch, a pipe clamp trigger switch, a mechanical charge level indicators, a foil gauge sensor, a strain type charge level indicator and a bunker safety controller, wherein the mechanical differential pressure gauge and the electronic differential pressure gauge are arranged at the top of a bunker, the pinch valve barometric switch controls a pinch valve, the pipe clamp trigger switch controls a pipe clamp, the mechanical charge level indicators are arranged in the upper and lower portions of the bunker respectively to monitor the charge level in the bunker, the strain type charge level indicator is arranged at the bottom of the bunker, and transmits charge level information to the bunker safety controller via the foil gauge sensor, and the electronic differential pressure gauge, the mechanical differential pressure gauge, the pinch valve barometric switch, the pipe clamp trigger switch and the mechanical charge level indicators are all connected with the bunker safety controller. The system and method have the advantages that the bunker can be managed intelligently, and safe and environment-friendly operation of the bunker is ensured.

Description

technical field [0001] The invention belongs to the field of silos, and in particular relates to a silo network intelligent control system and a control method. Background technique [0002] The silo is a device for storing materials. In order to fully reflect the advantages of the high-efficiency mixer, a premix silo is added. [0003] The silo in the concrete industry is used to store cement, fly ash, mineral powder or other additives in the concrete mixing station. Since the material is usually fed by air blowing, and the material is continuously conveyed through the screw conveyor, there are three main dangers that inevitably exist in the silo during use: ① overpressure, ② roof fall, ③ lack of material. The so-called overpressure means that the warehouse is in a positive pressure state during the feeding process, and the air is not discharged in time, which leads to exceeding the industry standard; the roof fall means that there is no material level display during the f...

AI Technical Summary

Problems solved by technology

The so-called overpressure means that the warehouse is in a positive pressure state during the feeding process, and the air is not discharged in time, which leads to exceeding the industry standard; the roof fall means that there is no material level display during the feeding process, causing the material to fill the warehouse body and sometimes rush out of the warehouse ;Material shortage means that during the material discharge process in the warehouse, the material storage reaches the lower limit, and there is no warning on the material level, which affects production

These hazards are caused by poor operational controls
