The anti-blocking rotary bucket type contracting device is simple in structure and has the characteristics of coal blockage prevention, contracting rate adjustment, small error, high sample preparation efficiency, no dust pollution and the like.
Description
Technical field
The utility model relates to a kind of reduction device, and a kind of anti-blocking rotation bucket type reduction device particularly is mainly used in large-size thermal power plant and other large-scalely enters the stove coal, enters in the sampling systems such as factory's coal, automobile and train with coal unit.
Background technology
development based on the power construction cause, the raising that the continuous operation operation and management of the large capacity of fire coal power plant requires, ature of coal is gathered and processed sample testing amount and is increased, mechanization automatic sampling collection equipment has progressively substituted artificial sample, its complexity is more and more higher, in the mechanization sampling design, reduction device is an apparatus that is mainly used to complete the contraction sample, it simultaneously is also the key equipment in sample-preparing system, in sample-preparing system, the effect of reduction device is to allow sample flow, rotating bucket is along with electric machine rotation, intercept part coal sample stream by two division adjustable ports on the del rotating bucket and realize division.In sampling check, the quantity of extraction is more, and minute cloth cover is more even, and result is more accurate, and precision is higher.
Because ature of coal is assorted, wide in variety and seriously inhomogeneous, extract representative sample difficult.The increment of different occasions, needs, coal, the check of ature of coal in batches has the regulation of strict number, weight and distribution thereof, guarantees that the sample that collects is representative, is impossible but whole increments of being adopted all will be chemically examined.Take out the representational a small amount of sample of a part and chemically examine from a large amount of samples of having adopted, by the even portioning of coal sample, more therefrom accept or reject by a certain percentage and complete division.The coal sample amount that last contraction becomes is division ratio with the ratio of the whole increment amounts of adopt.Sampling only needs as required sample size to regulate division ratio, simultaneously, to guarantee when rotating bucket rotate coal sample through stream the time turn at least the thoughtful n of l all (n is integer) in asking.
Thieff hatch on rotating bucket and the granule size of coal dust affect the size of division ratio, and the size of division ratio becomes the forward ratio on the impact of division precision with the size of division ratio; The rotating bucket speed of rotation is to coal sample miscarriage living " cutting ", and the speed of rotating bucket and the rotating speed of motor also have certain impact to the division precision.
Summary of the invention
The purpose of this utility model is, provides a kind of simple in structure, the anti-blocking rotation bucket type reduction device that charging hole adjustable dimension, division ratio can be regulated.
In order to realize above-mentioned task, the utility model adopts following technical solution:
A kind of anti-blocking rotation bucket type reduction device comprises cylindrical shell, it is characterized in that upper cover plate is arranged above cylindrical shell, on the cover board is connected with feed pipe, is connected with below cylindrical shell and abandons the coal pipe; On the cover board the central authorities of side are provided with the rotating shaft that is connected with cylindrical shell external motor and speed reduction unit, this rotating shaft is passed cover plate and is positioned at cylindrical shell, is connected with rotating bucket under rotating shaft, has two division adjustable ports on rotating bucket, the rotating bucket below is connected with the outlet coal sliding tube, and a manhole door is arranged on cylinder lateral wall.
Other characteristics of the present utility model are:
Described rotating bucket is the del rotating bucket; Also be provided with slide plate on two division adjustable ports, conveniently regulating the size of thieff hatch, thus the size of regulating division ratio,
One coal scraper plate also is housed on described rotating bucket.
Anti-blocking rotation bucket type reduction device of the present utility model, simple in structure, error is little, is difficult for chute blockage, and sample preparation efficient is high, no dust pollution.
Description of drawings
Fig. 1 is anti-blocking rotation rotary hopper-type reduction device structural representation of the present utility model;
Mark in figure represents respectively: 1, cylindrical shell, 2, rotating bucket 3, upper cover plate, 4, the division adjustable port, 5, feed pipe, 6, the manhole door, 7, revolving shaft, 8, the outlet coal sliding tube, 9, abandon the coal pipe.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Technical thought of the present utility model is, the del that rotating bucket arranges, above two thieff hatchs, also be provided with slide plate conveniently to regulate the size of thieff hatch on thieff hatch, thereby regulate the size of division ratio, be provided with reduction gear on revolving shaft, more easily regulate the size of division ratio, division ratio is adjustable, sampling quantity is controlled, good function and efficient, fabulous control sample rate and sample precision, have the manhole door on the cylindrical shell wall, convenient maintenance.
Referring to Fig. 1, the present embodiment provides a kind of anti-blocking rotation bucket type reduction device, comprises cylindrical shell 1, and upper cover plate 3 is arranged above cylindrical shell 1, is connected with feed pipe 5 on cover plate 3, and cylindrical shell is connected with for 1 time abandons coal pipe 9; Central authorities above cover plate 3 are provided with the rotating shaft 7 that is connected with cylindrical shell 1 external motor and speed reduction unit, this rotating shaft 7 is passed cover plate 3 and is positioned at cylindrical shell 1, rotating shaft is connected with rotating bucket 27 times, have two division adjustable ports 4 on rotating bucket 2, rotating bucket 2 belows are connected with outlet coal sliding tube 8, and a manhole door 6 is arranged on cylindrical shell 1 sidewall.
In the present embodiment, cylindrical shell 1 is cylindrical, and two division adjustable ports 4 are rectangle, on two division adjustable ports 4, the slide plate that can regulate size are arranged.
Rotating bucket 2 is del, and a coal scraper plate also is housed on rotating bucket 2, can remove the long-pending coal on rotating bucket 2.
Connect external motor and speed reduction unit, the size of more easily regulating division ratio in rotating shaft 7; When making, feed pipe 5 is goed deep into cylindrical shell 1, with the near distance of division adjustable port 4 a bit, be mainly to prevent that coal sample from descending slowly and lightly, the part coal sample can not be gathered, and makes the sample coal sample can enter more uniformly rotating bucket 2 inside, sampling is just representative, sampling precision is also high.
Adopt anti-blocking rotation bucket type reduction device of the present utility model, after operation, coal dust is flowed into by feed pipe 5, drive rotating bucket 2 rotations by motor and reductor, division adjustable port 4 on rotating bucket 2 is collected the coal sample that flows into from feed pipe 5, the coal sample of collecting enters collection sample bucket by outlet coal sliding tube 8, and other coal flows out through abandoning coal pipe 9.Can regulate when sampling quantity of division by the size of regulating electric machine rotating speed, thieff hatch and the time of sampling.
