Description
Technical field
The utility model is related to a kind of sampling division system, more particularly to a kind of Sampling Machine belt division system.
Background technology
Thermal power generation is the main generation mode of China, and coal is that fuel main comes during thermal power generation
Source.Therefore combustion management is most important during thermal power generation, while combustion management is also a complicated engineering.Coal
The acquisition of qualitative data need to be by adopting, making, changing three processes, and this three processes are connected each other and independent mutually, any one
Link, which is made a fault, can all influence the degree of accuracy of subsequent analysis result.And the reasonability of the wherein sampling process of coal is most to attach most importance to
The link wanted, this link has influence on the 80% of the result of laboratory test degree of accuracy.The sampling process of coal include Sampling Machine sampling, it is broken,
Division and the Four processes that keep sample.Division mode common at present has two kinds, and one kind is roller leakage modus ponens, and one kind is that belt is swept
Formula.But both division modes have certain defect, roller leakage modus ponens can not realize the Automated condtrol of division ratio；Belt
Sweep formula and carry out division according to fixed division ratio, cause its result inaccurate.In order to result it is inaccurate the problem of, application
Number be 201210270841.5 patent《A kind of system and method for intelligent division of coal samples in heat power plant》By being set at drill bit
Bucket weighing device is put to measure the quantity at dump skip to control division ratio, to improve the accuracy of testing result, to a certain degree
On solve problem, but still there is system complex and coal sample is transported to using during device in dump skip and easily let out
Leakage, causes have certain error in the coal sample finally collected and dump skip between coal amount, influences the accuracy of result.Existing contracting
Divide device control to be controlled using constant division number of times, because raw coal sample is uneven by the amount on division belt after crushing, make
It is inconsistent into division increment amount.
Utility model content
The purpose of this utility model is that offer is a kind of simple in construction and can accurately measure coal sample weight and rationally controlled
Division works, it is ensured that the consistent Sampling Machine belt division system of division increment amount.
This Sampling Machine belt division system that the utility model is provided, including division belt, it also includes coal influenza should
Device, reduction device, collection sample bucket, weighing device and PLC control cabinet, coal stream inductor and reduction device are arranged on division belt, collect sample
Bucket position is connected in the feed opening under division belt with reduction device, and it is lower for measuring coal in collection sample bucket that weighing device is located at collection sample bucket
Weight；Whether there is coal to control whether reduction device works on coal stream inductor detection division belt, contracted when having detected coal stream
The work of point device makes the coal stream after division enter when detecting that coal amount reaches sampling request in collection sample bucket to weighing device in collection sample bucket
Control reduction device is stopped.
In order to reduce the impulsive force of coal sample dropping process, the degree of accuracy of check weighing is improved, makes the reduction device and the collection sample
Bucket is connected by Z-type pipe.
In order to further reduce the impulsive force of coal sample dropping process, make the collection sample bucket is shaped as funnel type, the Z-type
The inwall that the bottom of pipe stretches into collection sample bucket with collection sample bucket is fitted.
In order to further improve the accuracy of coal amount in collection sample bucket, the end for stretching into collection sample bucket in Z-type pipe is externally provided with switch
Valve.
In order to avoid collection sample bucket is rocked by coal sample impact, being provided with the bottom centre position of the collection sample bucket is used to position
Groove.
Preferably, the weighing device includes gravity sensor and weight display screen.
In order to realize the fixation of collection sample bucket, provided with the projection for being matched with the groove on the gravity sensor.
The utility model detects whether there is coal on division belt to control contracting by coal stream inductor in use
Divide whether device works, reduction device work makes the coal stream after division interior to weighing device detection into collection sample bucket when detecting coal stream
Coal amount reaches in collection sample bucket controls reduction device to be stopped during sampling request, simple in construction and ensure that taken coal sample
The accuracy of weight, the reasonability of division is reasonably controlled by weight, it is ensured that increment amount is consistent, beneficial to raising testing result
The degree of accuracy.
Brief description of the drawings
Fig. 1 is the arrangement schematic diagram of one preferred embodiment of the utility model.
Illustrate sequence number：
1-division belt, 2-coal stream inductor, 3-reduction device, 4-collection sample bucket, 6-PLC control cabinet, 7-Z-type pipe,
8-switch valve, 51-gravity sensor, 52-weight display screen.
Embodiment
As shown in figure 1, this Sampling Machine belt division system that the present embodiment is provided, including division belt 1, coal influenza should
Device 2, reduction device 3, collection sample bucket 4, weighing device, PLC control cabinet 6, Z-type pipe 7 and switch valve 8, weighing device include gravity sensitive
Device 51 and weight display screen 52, coal stream inductor and reduction device are arranged on division belt, and gravity sensor is located under collection sample bucket
Weight for measuring coal in collection sample bucket.Collect sample bucket position in being connected under division belt by Z-type pipe with the feed opening of reduction device, Z
Type pipe can avoid coal stream from directly impacting the bottom of collection sample bucket, reduce impulsive force, improve the accuracy weighed, and will collection sample bucket
Shape be designed as funnel type, make Z-type pipe bottom stretch into collection sample bucket in collection sample bucket inwall fit, with it is further reduce punching
Hit power improve check weighing result the degree of accuracy, also by be arranged on Z-type pipe stretch into collection sample bucket at switch valve can timely cut
