Description
Technical field
This utility model relates to metering control, it is specifically related to a kind of material on-line analysis constant load metering control system, refers to the continuous metering control system to conveying material on-line dynamic analysis in the applications such as metallurgy, electric power, mine, harbour, chemical industry, building materials, grain.
Background technology
At present, multielement in-line analyzer is arranged on the metering conveyer belt of operation continuously, and feed conveyer belt is with constant speed feed, it is desirable to material keeps certain load on metering conveyer belt, can only control to measure conveyer belt speed according to material load.Common controlling arrangement has a disadvantage in that
1. speed governing scale, mainly controls flow by control scale body speed, and material load speed is the slowest, will keep setting flow, thus cannot keep constant load；
2. constant speed scale, the speed of major control batcher, scale body runs with constant speed, will keep setting flow, also cannot keep the constant of material load；
3. conveyer belt craft variable frequency adjustment, to some extent solves the material uniformity on the conveyor belt, but, labor strength is big, and automaticity is relatively low.
Summary of the invention
In order to improve existing on-line analysis to the accuracy of material and the deficiency of former measure control mode, this utility model provides a kind of material on-line analysis constant load metering control system, this system not only solves original control mode and makes the inaccurate difficult problem of in-line analyzer, it can also be made also to increase in terms of automatization, also achieve the control of the continuous dynamic measuring of constant load.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: a kind of material on-line analysis constant load metering control system, including disintegrating machine, feed conveyer belt, metering conveyer belt, sets full suspension weighing balance frame at the charging aperture of described metering conveyer belt, full suspension weighing balance frame sets three groups of carrying rollers, set two load sensor framves respectively in full suspension weighing balance frame both sides, each load sensor frame sets load sensor respectively；Setting speed measuring device on full suspension weighing balance frame, be located at line analysis instrument apparatus on the shelf of metering conveyer belt, each load sensor, speed measuring device and on-line analysis instrument apparatus are connected with metering control cabinet respectively.
Described full suspension weighing balance frame is positioned at the charging aperture 200cm of metering conveyer belt.
This utility model uses a kind of material on-line analysis constant load metering control system designed by technique scheme, and scale body is taked combination type entirely to suspend measurement structure by this system, it is simple to dismantle and maintenance.In control mode, by constant load, scale body speed being carried out variable frequency adjustment, remain that conveyer belt material load is consistent with assumed load, namely material thickness remains at the thickness of setting, greatly improve the in-line analyzer accuracy to material analyzing, there is good using effect.
Accompanying drawing explanation
Fig. 1 represents of the present utility model and watches structural representation attentively；
Fig. 2 represents the structural representation of this utility model metering conveyer belt.
Detailed description of the invention
The structure of material on-line analysis constant load metering control system a kind of to this utility model illustrates below in conjunction with the accompanying drawings.
See Fig. 1 and Fig. 2; this utility model one material on-line analysis constant load metering control system; including disintegrating machine 1; feed conveyer belt 2; metering conveyer belt 3; charging aperture 4 at metering conveyer belt 3 sets full suspension weighing balance frame 7 at 200cm; three groups of carrying rollers 11 are set on full suspension weighing balance frame 7; two load sensor framves 10 are set respectively in full suspension weighing balance frame both sides; set two load sensors 9 on each load sensor frame 10 respectively, full suspension weighing balance frame 7 also sets protector for sensor frame for protecting sensor.Setting speed measuring device 8 on full suspension weighing balance frame 7, be located at line analysis instrument apparatus 6 on the shelf of metering conveyer belt 3, each load sensor 9, speed measuring device 8 and on-line analysis instrument apparatus 6 are connected with metering control cabinet 5 respectively.
During utility model works, material crushes through disintegrating machine 1, enters metering conveyer belt 3 through feed conveyer belt 2 through the charging aperture 4 of metering conveyer belt 3 after crushing.Material starts stress from load sensor 9 during through first group of carrying roller 11 of full suspension weighing balance frame 7, and when crossing the 3rd group of carrying roller 11, after load sensor 9, stress terminates.The signals such as weight of material are transmitted to metering control cabinet 5 by material by the load sensor 9 on full suspension weighing balance frame 7 and speed measuring device 8, and metering control cabinet 5 calculates material load by inner parameter scale body length and load sensor parameter.Metering control cabinet 5 need to set negative severe according to on-line analysis instrument apparatus 6, deviation according to assumed load Yu actual load, after PID arithmetic, output control signal, the speed of service of metering conveyer belt 3 is regulated by converter, make material with constant load by on-line analysis instrument apparatus 6, to reach to control the purpose of load.Metering control cabinet 5 carries out computing by gathering the rate signal come with the load signal calculated, calculate actual flow and cumulative amount, and then control to make material with constant negative material by being installed on the on-line analysis instrument apparatus 6 of metering conveyer belt 3, it is ensured that the accuracy that material thing is analyzed by on-line analysis instrument apparatus 6.
Claims (2)
1. a material on-line analysis constant load metering control system, including disintegrating machine, feed conveyer belt, metering conveyer belt, it is characterized in that at the charging aperture of described metering conveyer belt, set full suspension weighing balance frame, set three groups of carrying rollers on full suspension weighing balance frame, set two load sensor framves respectively in full suspension weighing balance frame both sides, each load sensor frame sets load sensor respectively；Setting speed measuring device on full suspension weighing balance frame, be located at line analysis instrument apparatus on the shelf of metering conveyer belt, each load sensor, speed measuring device and on-line analysis instrument apparatus are connected with metering control cabinet respectively.
A kind of material on-line analysis constant load metering control system the most according to claim 1, is characterized in that described full suspension weighing balance frame is positioned at the charging aperture 200cm of metering conveyer belt.
