Overview:
JGC type weighing belt feeder (stoker) is a tape feeder, belt scale, frequency electronic control as one of the feed metering equipment, widely used in metallurgy, electric power, coke, chemicals, building materials, wharf and other industries. Coal consumption is calculated to achieve a positive balance of ideal equipment is mainly coal equipment in closed state can not only uniform, continuous coal, and may be sub-furnace measurement, the thermal power plant in the milling system.
JGC type weighing feeder is also suitable for continuous conveying and metering of other industries in the field of bulk materials, and open-loop according to user requirements, the closed-loop flow control and plant management of regional networks.
Model and meaning:
working principle:
Stoker coal use tape drag operation, when the tape is pulled out from the coal bunker, driven by the tape, the tape by friction between the moving weight and balance forward, in order to achieve a continuous, uniform coal .
When the material passing through a power transmission mechanism acting on the load cell, produce a voltage proportional to the belt load signal into Totalizer; speed sensor attached to the cylinder, providing a series of pulses, each pulse represents a belt campaign frequency unit, the pulse is proportional to the belt speed. After weighing indicator weighing sensor and speed sensor receives two signals, through amplification, shaping, A / D conversion process and integration operation on the meter's display shows the cumulative volume and instantaneous volume of coal transported.
System features:
◆ weighing sensor with double seal, long life, good stability;
◆ speed signals using optical encoder, a speed signal is accurate and reliable, anti-jamming;
◆ has a detuning, anti-bias structure to ensure normal and stable operation of transport;
◆ use of electronic belt excellent performance of the company, to ensure accurate and long-term stability of the calculation;
◆ weighing indicator with optional RS232 / 485 communication interface;
◆ The optional frequency stepless speed running smoothly, not only saving energy, but also to meet the site open or closed loop regulation requirements of different flow;
◆ chain scraper cleaning device can automatically clean the dust foreign objects inside the machine;
◆ Perfect alarm system can promptly detect and exclude block of coal, coal-off, overload, over-temperature fault belt deviation;
◆ Configure temperature isolation gate to prevent hot air reflow, providing convenience for the safe production and maintenance.
