Abstract

The utility model relates to a mechanical type sampling contracting-separating device for granular materials, such as coal, ore, etc. The mechanical type sampling contracting-separating device is suitable for monitoring the material properties of thermal power plants, smelteries, etc. The device has a power-driven rotating material collecting groove, the broken granular materials fall from an upward patulous mouth of the material collecting groove and samples are extracted according to the predefined division ratio; the extracted samples are divided into two ways, one way is that the extracted samples are sent to a material collecting jar with a drying function and the other way is that the water in the samples is maintained by not heating and the extracted samples enter a material collecting box. The opening degree of the mouth of a rotating sample extracting material collecting groove can be adjusted to reach the needed ratio. The requirement of correctly extracting the samples and the probability theory can be realized with the device, the correct extracted samples can be given out once and the reliability and the work efficiency can be improved without manpower operation.

Description

Bulk sampling contracting-separating equipment

The present invention relates to a kind of to bulk material the sample device of division such as coal, ore for example.

For material composition and other characteristics to bulk materials a large amount of in the production routine are monitored, need carry out sampling analysis, for example will carry out continual sampling chemical examination to the ature of coal on thermal power plant's travelling belt, the process of this sampling chemical examination should be the sampling theory based on theory of probability, be that it is a collection, division process, this process should be able to guarantee to be captured on each parts of whole initial materials and take a sample, and only in this way sampling could correctly characterize the physicochemical characteristics of being gathered initial material.

Existing sampling division device all is manual operation, as " cross reduction device ", " riffle " etc., (seeing standard GB 474-83).Existing above-mentioned division device, its division process all require to the material particle that becomes the stacking shape cut apart, fusion, in heaps, cut apart again, fusion again, cut apart again ... send to detection until cutting apart remaining material.This cutting procedure of prior art is exactly the division process, because with manpower long-time operation repeatedly, work heavy and exist artificial error, because in principle, it is not to sample from each part of whole materials, but intercepts it partly quickly.Constantly stacking is cut apart the fusion operation in addition, will inevitably cause certain easily mistake composition loss in the former material, for example evaporation of institute's water content in the material, and this will cause the data distortion of material moisture.

Device of the present invention has embodied each the sampling principle of partly taking a sample from whole detected materials, has improved the reliability of accurate sampling, has reduced labor capacity, has improved efficient.

Design of the present invention is such: with the particle of detected material, forming a lot of shape arranges, the hopper of taking out with rotation, periodically from long string, intercept the sub-fraction sample, realized making by sample drawing and from a large amount of materials, taking out with having equal opportunities from the requirement of each local sampling of a large amount of materials.The most material that is not intercepted, the part that should be considered as being rejected.

For reduced sample is carried out detection of different nature, the sample of intercepting divides in the container that two-way is collected in drying function and in the container of no drying function to be deposited respectively, with guarantee to moisture content etc. easily the composition that scatters and disappears of evaporation carry out detection by quantitative.In our scheme, the temperature of drying container is controlled in the 50-80 ℃ of scope, never degenerates to guarantee the sample of being dried.

For former material is carried out division in difference extraction ratio, the gather materials aperture of notch of rotation is adjustable to reach required division ratio.

Device of the present invention, can be automatically once division go out to be used for two or more testing goal samples, reduced the interference that intermediate link is brought.

Below in conjunction with accompanying drawing an embodiment is described.

Fig. 1 is the main body synoptic diagram of embodiments of the invention,

Fig. 2-the 1st, the synoptic diagram of the sampling groove 2 of no material collecting box among Fig. 1,

Fig. 2-the 2nd, the synoptic diagram that Fig. 2-1 sampling notch aperture is regulated,

Fig. 3-the 1st has the insertion view of sampling groove 3 material collecting box 4 of material collecting box among Fig. 1,

Fig. 3-the 2nd, material collecting box is extracted view out among Fig. 3-1,

Fig. 4 is the structural representation of aggregate tank among Fig. 1.

Among Fig. 1, the A arrow represents that the initial material bulk goods that has been broken flows out the flow state that is the whereabouts shape from disintegrating machine, B is that turning axle 1 is in motor 7 sense of rotation under the drive of reducing gear 8, the 2nd, the sampling groove of no material collecting box, in the present embodiment, this hopper of taking out has five, and the 3rd, the hopper of taking out of material collecting box 4 is arranged, the 5th, the lid of aggregate tank 6, it rotates above jar 6 by direction B, and the 7th, motor, the 8th, reducing gear, the 9th, switchboard, the 10th, support, the 16th, stirrer gear, the 18th, axle 1 bottom is positioned at the material collecting tank mesopore, sampling by these hole material collecting tank 2 grades falls into aggregate tank 6, and sampling is stirred and dries moisture content wherein in this jar.

Fig. 2-the 1st takes out further specifying of hopper 2 among Fig. 1, and the 11st, notch aperture adjustable plate, it rotates around axle chain 12 and opens or closed angle, and the 13rd, locking mechanism, the state signal that Fig. 2-the 2nd, adjustable plate magnify.

Fig. 3-the 1st takes out further specifying of hopper 3 among Fig. 1, the 4th, the material collecting box that can extract out, it can be along C to pulling out, and the 14th, add the barrier apparatus of being located on the aperture adjustable plate 11, be used for further dwindling the division ratio of originally taking out hopper, originally take out the sampling division that hopper is used to keep material moisture content.

Fig. 4 is the synoptic diagram of aggregate tank 6, the 5th,,, be used for evaporating steam in the toilet-cleaning jar 6 to the lid on the aggregate tank 6 of being covered in that rotates with B in order to prevent that derelict grain from entering

jars

6,5 and 6 edge certain slit is arranged.The 16th, by the stirrer gear of B to rotation, the 17th, the removable bottom that can take out out, the oven dry material 18 when closed in the carrying jars 6, siccative 18 falls and carries out second-time breakage when taking out out, and the 15th, heating has insulator to isolate with jars 6, and bake out temperature is controlled at 50-80 ℃.

The present invention with as the way of above-mentioned embodiment explanation, from detected former expect pointwise draw samples, the more existing any dichotomy scheme of this scheme is superior, it can react the essence of tested material more accurately.

Another advantage of the present invention also shows in the present embodiment significantly, and promptly it is by power-actuated, and this has removed the heavy physical labor of artificial division from, has more deducted personal error.

Present embodiment is a concrete scheme that embodies the present invention's design, and any other scheme of all use the present invention designs also belongs within this patent protection domain.
