Description
Technical field
The utility model relates to a kind of thermal power generation station-service raw coal sample devices technical field, relates in particular to a kind of gate-type train sampling machine revert system.
Background technology
Thermal power generation is as a kind of generation modes maximum in China's electric system, and the main energy source of thermal power generation is in coal, in order to allow the energy producing in coal burning process change as far as possible fully, and raw coal self whether benefit be also directly connected to burning whether fully and the quality of energy conversion; Therefore, there is certain requirement fuel-burning power plant to the raw coal quality of its use, so raw coal sampling machine can be set conventionally, inspect the raw coal being used by random samples and whether can reach standard.
Gate-type Sampling Machine is as conventional a kind of raw coal sampling machine, and this gate-type Sampling Machine is mainly comprised of sampling small car, batcher, disintegrating machine, reduction device, sample collecting device, remaining coal handling system and big or small travel mechanism.First by drilling through formula sampling head, extract coal sample, by closed belt feeder, send into disintegrating machine, enter reduction device after fragmentation, the coal sample after division enters sample collecting device, and unnecessary coal sample enters raw coal compartment by remaining coal handling system.
But inventor finds in realizing process of the present utility model, there are some problems in existing gate-type Sampling Machine, such as remaining coal revert system exists airborne dust large, remaining coal can not be back to the problem in train loaded vehicle compartment completely, to surrounding environment, pollute very large like this, a large amount of remaining coals can not reclaim in time and cause very large waste, and tippler is weighed to loaded vehicle and also can be had error simultaneously, has affected the sampling and testing accuracy of whole Sampling Machine.
Utility model content
In order to solve the above-mentioned technical matters existing in gate-type Sampling Machine in prior art, the utility model provides a kind of gate-type Sampling Machine revert system that remaining coal reclaims of being convenient to.
A kind of gate-type train sampling machine revert system that the utility model provides, described gate-type train sampling machine comprises: disintegrating machine, the reduction device being connected with disintegrating machine, below reduction device, be provided with coal dropping port, it is characterized in that, described revert system comprises and is arranged on the coal spout being connected with described coal dropping port, the two parts that are at least provided with predetermined angular are set on described coal spout, and coal spout cross section is arc line shaped.
Preferably, on above-mentioned coal spout, be predefined for 50 °～70 °.
Preferably, above-mentioned coal spout is made by Buddha's warrior attendant material.
Preferably, on above-mentioned coal spout, be also provided with returning charge door.
Preferably, in above-mentioned arbitrary a kind of gate-type train sampling machine revert system, described revert system also comprises the coal breakage electric motor of shaker that is arranged on coal spout outside.
After adopting technique scheme, the two parts that are at least provided with predetermined angular are set on coal spout, and coal spout cross section is arc line shaped, can reduce coal flow resistance like this, and according to scene, need to change the trend of coal spout, when each point sampling, guarantee remaining coal can returning charge to railway carriage.Further, increase coal breakage electric motor of shaker, can guarantee, when any coal is situated between, in coal spout, not to be stained with coal.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of gate-type train sampling machine of relating to of the utility model embodiment;
Fig. 2 is the partial schematic diagram of a kind of gate-type train sampling machine revert system of relating to of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, it should be noted that, these specific descriptions just allow those of ordinary skills be more prone to, clearly understand the utility model, but not to limited explanation of the present utility model.
Embodiment
As shown in Figure 1, preferably, a kind of gate-type train sampling machine 1 that the present embodiment provides comprises: bracket upright post 2, and track girder 3, drive motor 4, is arranged on the sampling small car 5 on track girder 3, comprises sample devices, the sample making apparatus of sampling head; Pulpit 6, is provided with control operation platform and program control facility in pulpit 6, such as PLC control system; Revert system.Gate-type train sampling machine 1 comprises: disintegrating machine, the reduction device 7 being connected with disintegrating machine, below reduction device 7, be provided with coal dropping port, and revert system comprises the coal spout 8 being connected with coal dropping port, the two parts that are at least provided with predetermined angular are set on described coal spout, and coal spout cross section is arc line shaped.
As shown in Figure 1, Figure 2, the angle β between two sections of coal spout 8a, 8b is 50 °～70 °, and preferably optimum value is 60 °, can reduce coal flow resistance like this.And coal spout is arranged on described coal dropping port rotationally, can need to change the trend of coal spout according to scene like this, when each point sampling, guarantee remaining coal can returning charge to railway carriage.
Preferably, coal spout 8 is made by Buddha's warrior attendant material, because Buddha's warrior attendant material wear-resistant performance is very good, and lightweight, skin resistance is little, thus contribute to very much coal flowing in coal spout 8 again, and also maintenance cycle can be longer.And on coal spout 8, be also provided with returning charge door 9, can control better the moment of coal breakage.Preferably, coal spout 8 xsect in short transverse is of a size of 500mm * 400mm, so in terms of existing technologies, has greatly increased the size of coal spout 8, thereby allows coal breakage easily discharge further.
As described in Figure 2, preferably, in gate-type train sampling machine revert system, also comprise the coal breakage electric motor of shaker 10 that is arranged on coal spout outside, the electric power of electric motor of shaker is 300W; By coal breakage electric motor of shaker 10, can guarantee, when any coal is situated between, in coal spout, not to be stained with coal.
The optimal technical scheme that adopts the present embodiment to provide, while thoroughly having solved Sampling Machine operation, coal, problem that airborne dust is large are spread by former remaining coal revert system place, have eliminated the environmental pollution that coal dust causes, and meet environmental protection policy while making equipment operation; And the loaded vehicle compartment Weighing inaccurate problem causing while having solved original system operation; Also solve former gate-type Sampling Machine reliability and be subject to problem that effect on coal quality is large and the problem of the easy chute blockage of former revert system.
Finally it should be noted that, above-mentioned explanation is only most preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction.Any those of ordinary skill in the art; do not departing within the scope of technical solutions of the utility model; all can utilize way and the technology contents of above-mentioned announcement to make many possible changes and simple replacement etc. to technical solutions of the utility model, these all belong to the scope of technical solutions of the utility model protection.
