As is well known, electronic belt scales are dynamic measuring instruments that can continuously and automatically weigh materials on a conveyor belt without subdividing or interrupting the operation of the conveyor. Due to their high measurement efficiency, they are widely used in industries such as mining, ports, metallurgy, and building materials for bulk material transportation.
However, in many situations, belt conveyors are also used to transport bulk materials, but ordinary electronic belt scales cannot be applied, such as in underground coal mine environments where many areas contain flammable and explosive substances such as gas and coal dust. However, these occasions do require electronic belt scales to detect coal production.
In response to the problem of the need for electronic belt scales in coal mines, Guonuo Technology has integrated mining explosion-proof electrical technology and dynamic measurement technology of electronic belt scales, and designed and manufactured a mining explosion-proof electronic belt scale specifically suitable for flammable and explosive environments in coal mines.
The electrical components of the mining explosion-proof electronic belt scale are equipped with explosion-proof technology, including stainless steel sealed explosion-proof shells, intrinsic safety circuits, etc., to ensure its stable, safe, and reliable operation underground in coal mines.
At the same time, the mining explosion-proof electronic belt scale has all the functions of ordinary electronic belt scales, and has better resistance to harsh environments. The mining explosion-proof electronic belt scale can integrate computer, network information and other technologies to create a mining explosion-proof electronic belt scale measurement system that connects the ground and underground.
The main functions of the mining explosion-proof electronic belt scale measuring system are:
(1) The remote control function allows for production detection, parameter setting, calibration, and other operations of the underground explosion-proof electronic belt scale in the ground monitoring center, without the need to open the instrument explosion-proof shell for operation. It is simple, convenient, and improves safety.
(2) In order to facilitate underground data query and improve data transmission efficiency, the explosion-proof electronic belt scale for mining is equipped with a belt scale substation, which can optimize the signal, centralize digital display, ensure accurate and real data transmission, and facilitate underground operators to view data.
(3) The mining explosion-proof electronic belt scale has a power-off protection function. In the event of communication or power interruption, the belt scale can form its own system, remember the production during the period, and continue to operate on the basis of weighing after communication or power is restored. It automatically accumulates and data can be transmitted and shared. The upper computer of the ground monitoring center can also query the measurement data during communication or power interruption.
(4) It can comprehensively query data, including shift accumulation, daily/monthly/annual accumulation, total accumulation, flow curve, historical data records, etc. It can generate reports and perform printing operations.
(5) Self diagnosis and automatic alarm function, real-time self-monitoring of operating conditions, fault diagnosis, automatic alarm, automatic recording, automatic diagnosis of communication faults, sensor faults, and scale body faults.
(6) Configure upper computer software system, industrial configuration software programming, menu options, easy operation. The page displays the name, operating status, flow rate, load, and other information of the mining explosion-proof electronic belt scale, making it convenient for regulatory personnel to grasp the actual operation of the belt scale.
(7) The measurement data and equipment operation status of the mining explosion-proof electronic belt scale can be remotely browsed and viewed through the network, making it convenient for leaders to manage.
