Description
Technical field
The utility model is mainly concerned with sample making apparatus field, refers in particular to a kind of sample pulverizer.
Background technology
In numerous technical fields of prior art, all need the making carrying out sample of material.Such as, in the field tests of coal sample, before carrying out multiple analysis of experiments to coal sample, just need to make representative coal charge sample.In manufacturing process, often need to carry out leading fragmentation to coal sample, and then collect, can not there be the loss of sample period, can not make sample that some physics or chemical change occur, otherwise will impact final result of the test.
In sample making course, what be often used to is sample pulverizer, and it utilizes crushing cutter to carry out crushing operation to the material sent into from material bin, and then is directly poured in a bottle by the material after fragmentation and collects.In this process, often there is following problem:
1, when receiving flask is less, because cutter at high speeds in pulverizing process rotates, the heat of generation can not distribute in time, causes the coal dust temperature that obtains too high, affects quality of pc, even the representativeness of sample is affected.
2, coal dust enters after in bottle, can produce certain air-flow, and under the effect of air-flow, coal sample floatingly can affect the accuracy of collecting, or is taken away by other equipment (as dust collection equipment).And a large amount of existence of air-flow also can have influence on the smoothness sending into coal charge.
3, under the impact of bottle inner sealing air-flow, the screen cloth of output section often occurs the problem of hanging powder, need dismounting cleaning coal dust to remain, make it be unlikely to block screen cloth, coal dust sticks to problem screen cloth also easily producing caking, the contaminated samples that drops for a long time.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existed for prior art, the utility model provide a kind of simple and compact for structure, the sample pulverizer with return air channel that reliability and precision are pulverized in sample preparation can be improved further.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of sample pulverizer with return air channel, comprise frame, Control Component and powder process assembly, described powder process assembly includes hopper, crushing knife mechanism, disposable box and actuator, described material bin is positioned at the top of crushing knife mechanism, described crushing knife mechanism comprises crushing chamber and is installed on the crushing knife in crushing chamber, described crushing knife is connected with the output of actuator, described crushing chamber is communicated with disposable box, between described disposable box and material bin or crushing chamber, return air channel is set, by return air channel between material bin and disposable box or disposable box and crushing chamber form circulating current.
As further improvement of the utility model: described disposable box is the cavity with certain altitude.
As further improvement of the utility model: described disposable box is arranged more than one vibrations blanking parts.
As further improvement of the utility model: the interface of described disposable box and crushing chamber arranges blanking deflector.
As further improvement of the utility model: the interface of described disposable box and crushing chamber arranges screen cloth.
As further improvement of the utility model: the bottom of described disposable box is provided with the bottle that gathers materials.
As further improvement of the utility model: described disposable box is arranged in the surrounding of crushing chamber ringwise and is communicated with crushing chamber.
As further improvement of the utility model: the interface of described disposable box and crushing chamber arranges screen cloth.
As further improvement of the utility model: arrange sealing between the cavity top of described disposable box and the support plate of material bin.
As further improvement of the utility model: the interface of described disposable box and crushing chamber is arranged at the side of disposable box cavity.
Compared with prior art, the utility model has the advantage of: the utility model is connected to form Inner eycle air-flow at material bin-disposable box-return air channel or material bin-crushing chamber-return air channel three, coal dust sedimentation falls into disposable box, non-subsidence part divide through return air channel reclaim enter pan feeding place, one can reclaim the coal dust in reflux gas, air-flow forms Inner eycle, coal dust does not contact air, the hermetically sealed design of fuel pulverizing plant, do not leak powder, not contaminated air, reduces toxic emission, improves working environment; Two, increase area of dissipation, the Inner eycle air-flow of formation is also beneficial to heat radiation, and solve because cutter at high speeds in pulverizing process rotates, the heat of generation can not distribute in time, causes the coal dust temperature that is worth too high, affects the problems of quality of pc.Meanwhile, after forming Inner eycle air-flow, screen cloth will not hang powder, do not need dismounting cleaning coal dust to remain, non clogging screen net, solves on original device screen cloth and easily hangs powder, blocking screen cloth causes the abatement of wind, and coal dust to stick on screen cloth caking for a long time and to drop the problem of contaminated samples.

Detailed description of the invention
Below with reference to Figure of description and specific embodiment, the utility model is described in further details.
Embodiment 1: as shown in Figure 1, the sample pulverizer with return air channel of the present utility model, comprise frame 1, Control Component 2 and powder process assembly, powder process assembly includes hopper 3, crushing knife mechanism 4, disposable box 5, gather materials bottle 6 and actuator 7, material bin 3 is positioned at the top of crushing knife mechanism 4, crushing knife mechanism 4 comprises crushing chamber and is installed on the crushing knife in crushing chamber, crushing knife be connected with the output of actuator 7 and under the driving of actuator 7 high-speed rotation, fragmentation is carried out to the material (as: coal sample) sent into from material bin 3, actuator 7 can adopt motor or other actuators according to actual needs.Disposable box 5 sent into by broken complete material, utilizes the collection of disposable box 5 and guiding that material is sent into the bottle 6 that gathers materials be arranged in bottom disposable box 5, completes the collection of material.The utility model is at disposable box 5 and material bin 3 or arrange return air channel 8 between disposable box 5 and crushing chamber, return air channel 8 is utilized to be communicated with crushing chamber with disposable box 5 or disposable box 5 by material bin 3, namely material bin 3-disposable box 5-return air channel 8 or material bin 3-crushing chamber-return air channel 8 three form Inner eycle air-flow, coal dust sedimentation falls into disposable box 5, and non-subsidence part is divided to reclaim again through return air channel 8 and entered material bin 3 or crushing chamber place.By arranging return air channel 8, one can utilize return air channel 8 to reclaim coal dust in reflux gas, and air-flow forms Inner eycle, coal dust does not contact air, and whole fuel pulverizing plant forms hermetically sealed design, does not leak powder, not contaminated air, reduces toxic emission, improves working environment.Two by arranging return air channel 8, can also increase area of dissipation, and the Inner eycle air-flow of formation is also beneficial to heat radiation.
