Abstract
The utility model discloses a rotary dividing machine for a laboratory, which comprises a rotating main shaft, a feeding hopper positioned at one end of the rotating main shaft, an agitating blade positioned in the feeding hopper and sleeved on the rotating main shaft, a sample division cylinder sleeved on the rotating main shaft and connected with the feeding hopper, a thrower positioned in the sample division cylinder and sleeved on the rotating main shaft and a reserved sample chute mounted at the notch, wherein a notch is formed on one side of the sample division cylinder on the peripheral direction. By applying the technical scheme, when falling off, materials are uniformly sprinkled on the thrower through rotating the agitating blade; and because the thrower is positioned in the sample division cylinder, a part of materials flies into the reserved sample chute mounted at the notch on the peripheral direction of the sample division cylinder under the action of centrifugal force, so that the division precision is ensured by uniform feeding. Compared with the prior art, the utility model solves the problem of inaccurate division precision caused by non-uniform feeding in the prior art.
Description
Technical field
The utility model relates to division machine technology field, more particularly, relates to a kind of laboratory with rotating the division machine.
Background technology
The division machine is mainly used in the sampling sample making course of coal, mine raw material, grain of ore, the fuel-burning power plant of steel plant etc.
Coal is the mineral products that quality is extremely inhomogeneous, quality discrepancy is very big as using the energy extremely widely.Quality difference, price variance are very big.In the coal transaction, to accomplish utmost fair dealing, need the quality of coal be detected, thereby the quality of accurately judging coal accurately be fixed a price for coal.The sampling sample preparation of coal and chemical examination are the means that realize that the coal quality is accurately analyzed, and the sample preparation link of wherein taking a sample is particularly important, facts have proved, account for about 85% of coal quality restriction total error by the sampling error that sample preparation produced.The division machine is one of equipment extremely crucial in the sampling sample making course, and on behalf of the feed separation of materials quality, it can.Whether there are deviation, precision whether to satisfy system requirements during division, directly determined the reliability and the reliability of total system.
In coal sampling sample preparation field, having now most popular is slot type division riffle.This slot type division riffle is a kind of artificial division mode, the hand-held dustpan that material is housed of operator moves back and forth, with material be sprinkled into that two groups of relative populations equate, in the cell of cross arrangement, the material in the cell is divided in two hoppers of two parts of equal belows of packing into.Because the homogeneity of the charging of existing slot type division riffle and the relation that how much has of pouring material at every turn, the inhomogeneous precision of division that causes of charging is inaccurate.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of laboratory with rotation division machine, to solve the inhomogeneous inaccurate problem of precision that causes division of charging in the prior art.
The utility model provides a kind of laboratory with rotating the division machine, comprising:
Rotary main shaft;
Be positioned at the feeder hopper of described rotary main shaft one end;
Be positioned at described feeder hopper, and be set in the stirring vane on the described rotary main shaft;
Be set on the described rotary main shaft, and the branch sample tube that links to each other with described feeder hopper, this minute the sample tube have breach in a side of circumferencial direction;
Be positioned at described minute sample tube, and be set in the dish that gets rid of on the described rotary main shaft;
Be installed in the chute that keeps sample of described indentation, there.
Preferably, the downside of described minute sample tube is installed and is abandoned the sample chute.
Preferably, also comprise and be installed on described minute sample tube and the described adjustable plate that keeps sample between the chute.
Preferably, the specification of the breach on the circumferencial direction of the specification of described keep sample chute and the breach of described minute sample tube touching position and described minute sample tube is identical.
Preferably, the scope of the breach angle on the circumferencial direction of described minute sample tube is 0～90 degree.
Preferably, described stirring vane, the described axial line that gets rid of dish and described rotary main shaft overlap.
From technique scheme as can be seen, the rotation under power source drives of the utility model embodiment rotary main shaft drives stirring vane simultaneously and gets rid of disc spins, and after material was poured feeder hopper into, the stirring vane of rotation was trickled down getting rid of on the dish in rotation uniformly with material.Be positioned at branch sample tube owing to get rid of dish, therefore a part of material flies under action of centrifugal force in the chute that keeps sample of indentation, there on the circumferencial direction that is installed in branch sample tube, and another part hits and falls on barrel.Use the technical program, when material falls during the stirring vane of rotation material trickle down uniformly and getting rid of on the dish, charging uniformly guarantees the precision of division, compared with prior art, has solved the inhomogeneous inaccurate problem of precision that causes division of charging in the prior art.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, the accompanying drawing that describes below only is some embodiment that put down in writing among the application, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The laboratory that Fig. 1 provides for the utility model embodiment a kind of structural representation of rotation division machine;
The laboratory that Fig. 2 provides for the utility model embodiment another kind of structural representation of rotation division machine;
The laboratory that Fig. 3 provides for the utility model embodiment the third structural representation of rotation division machine.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that is obtained under the creative work prerequisite.
Embodiment one
The laboratory that the utility model embodiment provides with a kind of structural representation that rotates the division machine as shown in Figure 1.Wherein:
1 is feeder hopper, and 2 is stirring vane, and 3 for getting rid of dish, and 4 for dividing the sample tube, and 5 for keeping sample chute, and 6 is rotary main shaft.
From technique scheme as can be seen, the rotation under power source drives of the utility model embodiment rotary main shaft 6, drive stirring vane 2 simultaneously and get rid of dish 3 rotations, after material was poured feeder hopper 1 into, the stirring vane 2 of rotation was trickled down getting rid of on the dish 3 in rotation uniformly with material.Be positioned at branch sample tube 4 owing to get rid of dish 3, therefore a part of material flies under action of centrifugal force in the chute 5 that keeps sample of indentation, there on the circumferencial direction that is installed in branch sample tube 4, and another part hits and falls on barrel.Use the technical program, when material falls during the stirring vane 2 of rotation material trickle down uniformly and getting rid of on the dish, charging uniformly guarantees the precision of division, compared with prior art, has solved the inhomogeneous inaccurate problem of precision that causes division of charging in the prior art.
