Abstract
The invention belongs to the technical field of instruments, particularly relates to a fire coal meter, and aims to solve the problems of big errors, high cost and other problems occurring when fire coal of a chain grate boiler is measured by adopting a sensor. The fire coal meter is characterized by comprising a rotary table arranged on a rotating shaft, a magnet, a magnetic control switch matched with the magnet, and a digital display meter connected with the magnetic control switch through an electric wire, wherein the magnet is arranged on the rotary table. The fire coal meter has the advantages of convenience in assembly, accurate measurement, low cost and the like.
Description
Technical field
The invention belongs to the measurement instrument technical field, be specifically related to a kind of coal-fired gauging table.
Background technology
Existing dissimilar chain-grate boiler mostly carries out the fire coal metering with electronic belt scale, and concrete grammar is that a sensor is installed below belt, measures by sensor.This method is very strong to the dependence of belt, and belt is subjected to easily multiple cause influences such as weather, temperature, belt are new and old, tightness, so error in dipping is big, and this method investment is big, the cost height.
Summary of the invention
The present invention is primarily aimed at when chain-grate boiler adopts the sensor metering coal-fired and has problems such as error is big, cost height, and a kind of easy for installation, accurate measurement, coal-fired gauging table that cost is low are provided.
The present invention addresses the above problem the technical scheme of taking to be:
A kind of coal-fired gauging table comprises the rotating disk that is installed in the rotating shaft, wherein: also comprise magnet, with magnet magnetic switch that is complementary and the digital wash that is connected with magnetic switch by electric wire, described magnet is installed on the rotating disk.
The present invention adopts technique scheme, rotating disk is installed in the rotating shaft of feeder, magnetic switch is installed on the feeder body, constantly adjust feeder rotating speed coal-supplying amount during operation, every through circling, the magnetic switch closure once, digital wash is accumulated a number, so just, can automatically accumulate and supply with coal-fired quantity, this method is disobeyed shameless band, can not be subjected to the influence of belt.Therefore, compared with prior art, that the present invention has is easy for installation, accurate measurement, low cost and other advantages.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of coal-fired gauging table, comprise the rotating disk 1 that is installed in the rotating shaft 6, wherein: also comprise magnet 2, with magnet 2 magnetic switch 3 that is complementary and the digital wash 5 that is connected with magnetic switch 3 by electric wire 4, described magnet 2 is installed on the rotating disk 1.
Using method of the present invention: rotating disk 1 is installed in the rotating shaft 6 of feeder, magnetic switch 3 is installed on the feeder body, and rotating shaft 6 drives rotating disk 1 rotation, whenever circle, magnetic switch 3 closures once, numeral of digital wash 5 accumulative total just can calculate coal-fired quantity according to this numeral.
Claims (1)
1. coal-fired gauging table, comprise the rotating disk (1) that is installed in the rotating shaft (6), it is characterized in that: also comprise magnet (2), with magnet (2) magnetic switch (3) that is complementary and the digital wash (5) that is connected with magnetic switch (3) by electric wire (4), described magnet (2) is installed on the rotating disk (1).
