Description

Power-less automatic continuous sampler

The utility model belongs to quality inspection sampler in a kind of granular material production run.

Quality for the granular material that guarantees to produce by the plurality of raw materials proportioning, often will extract sample segment to its product in process of production tests, whether reach desired in advance technical indicator so that understand its product, and then feed back to preceding working procedure, proportioning is carried out necessary adjustment, make it satisfy intrinsic technical indicator to greatest extent.

The sampling method of custom generally has two kinds: the one, and take a sample at regular intervals once (determined by inspection frequency interval time) is commonly called as " instantaneous sample ".The 2nd, sampling is carried out synchronously with production, is commonly called as " sample continuously ".

The instantaneous sample method is fairly simple, and what equipment it does not need, and just opens a sample tap at a certain position of granular material conveying equipment, and timing or not timing ground take out sample, test.The shortcoming of this kind method maximum is exactly that institute's sample thief can not be represented between two sub-samplings quality of integral product in the whole process, and is promptly representative relatively poor, therefore too high if product quality requires, or the fluctuation of furnish component material quality is big, should not adopt this method.Though this method has very big shortcoming, it is simple, thereby is still adopting in many enterprises (particularly, small cement plant), and this also is to cause one of these enterprises (especially cement industry) principal element that product quality is not high.

Because continuous sampling is to carry out synchronously with production, overcome the drawback of instantaneous sample method, institute's sample thief is representative, and its analysis result is produced commander, very important to end product quality, at present many enterprises's (especially cement industry) are the active adoption continuous sampling all.

The method of each cement mill serial sampling of China has two kinds at present: the one, and traditional " steel wire bullet sample method "; The 2nd, " rap cutter spiral sampling method ".

Steel wire bullet sample method is to open a duck eye to insert steel wire below the conveying mangler shaft center line of screw machine, one end of steel wire stretches into certain distance in the reamer, be generally about 20mm, the other end of steel wire is fixed on the proper site of the outer wall or the sample-collecting box of screw machine, when reamer the time at convey materials, the reamer blade is stirred steel wire, and it is external that the material in the screw machine is ejected screw machine, reaches the purpose of serial sampling.The advantage of this method is a simple structure, and economy is easy to do.But maximum shortcoming is the purpose that does not often reach serial sampling sometimes, and reason is that the sample that ejects in official hour is checked use inadequately if too smallly wide open, particularly runs into material tide or rainy weather, and the discharging duck eye is easy to stop up, and makes the sampling failure.Otherwise as with little wide open too much, the material in the screw machine easily takes place have the raft material to flow out from flow phenomenon (particularly mobile big material) in official hour, not only can't check, and influence workshop hygiene.Even little wide open big or small more satisfactory, but in use still will be subjected to expecting the influence of various factors such as the degree of wear of matter, weather, flow pressure, steel wire, when occurring during bullet stream Shi Duan etc. influence sampling quality.

Rap cutter spiral sampling method is that suitable position is opened a suitable hole above the conveying mangler shaft center line of screw machine, rap cutter spiral sampler level is installed in the place, hole, the one end inserts the hole, be advisable to bump less than the reamer in the screw machine, as long as start the control device of rap cutter spiral sampler, rap cutter spiral sampler just can continuously be taken out the material in the end that falls in the course of conveying in the screw machine in the rap cutter spiral sampler insertion screw machine under the rap cutter is forced, this method has overcome the shortcoming of steel wire bullet sample method, has reached the purpose of serial sampling.But its complex structure is made difficulty, moves reliably inadequately, and cost is higher, and it is more easy to wear particularly to work in the granular material environment, and the big many shortcomings of maintenance load have influenced and applied.

The utility model is for not enough separately provide a kind of simple in structure, easy to make of above-mentioned two kinds of continuous sampling systems in the granular material production run, the unpowered automatic continuous sampling device of service-strong are provided.

The unpowered automatic continuous sampling device a kind of by shell 1, that sample-collecting box 6 is formed is characterized in that being equipped with in the shell 1 club 4 that is with pad 5 and spring 2.And an end of shell 1 is equipped with a blind nut 3 with holes.

According to above-described club 4, it is characterized in that the diameter of the diameter of hemisphere face body greater than club 4 bars.

According to above-described club 4, its feature is that also the end that club 4 has hemisphere has a plane convex, and the slightly larger in diameter of convex is in the diameter of the hemisphere face body of club 4 and the diameter of spring 2.

According to above-described blind nut 3, the slightly larger in diameter in Qi Gai hole is in the diameter of club 4 straight-bars.
