Abstract

An impeller accelerating crusher with airflow circulation is to solve problems such as much energy consumption, low efficiency, influence to purity and fineness in prior technology. The utility model frame is fixed with a machine box and a power device with features as: a semi-enclosed impeller in the case is to form an accelerating crushing device with impeller; an inlet and an outlet of the case are connected with a separation device respectively; the separation device is a separator, a tangential inlet stays at upside profile of such separator, and the tangential inlet is connected to the outlet of the case by means of connect pipe and the low part of the separator is connected with the inlet of the case by means of connect piping to form an airflow circulation separation system, which is characterized in that strong crushing capacity to crush grain to nanometer level with high utilization rate of valid energy. The separation device gives circulating separation to stuff and super-fine powder escape from the outlet and uncrushed powder enters crusher again until total crushing.

Description

The air-flow circulation impeller is quickened pulverizer

Technical field

The utility model belongs to a kind of disintegrating apparatus, and particularly a kind of air-flow circulation impeller is quickened pulverizer.

Background technology

At present, superfine communication technique extensive use in the every field of national economy, and become enhance product performance, the effective ways of quality, class and economic value added, caused the attention and the concern of various circles of society, various micron ultra shifters also arise at the historic moment.At present, ultramicro grinding equipment mainly contains ball mill, Raymond machine, eddy mill, high pressure homogenizer, colloid mill or the like.Because therefore the crushing process more complicated, does not set up complete crushing mechanism in the pulverizing field, ubiquity two hang-ups, the one, and the effective energy utilization rate that is used to pulverize is extremely low, pulverizes the energy consumption height, and the 2nd, the fiber-like material is difficult to ultramicro grinding.In addition, material is subjected to strong extruding, the shearing that is listed as, grinds, cuts mechanisms such as stranding, turbulence in the process of pulverizing, though reached the purpose of comminuting matter, but material appearance heavy metal break flour particulate in various degree in the process of accepting the metal material grinding is peeled off to be disengaged, as disengaging of heavy metals such as chromium, nickel, cadmium, titanium, iron, copper, lead, aluminium, arsenic, make the material of ultramicro grinding be subjected to severe contamination.As colloid mill, this micron ultra shifter is pulverized material in the mode of extruding and grinding.It mainly is made of the stator that has the truncated cone chamber that rotor and of support, casing, actuating unit and a truncated cone shape cooperates with rotor.On the conical surface of rotor and stator, have the tooth lapping that to shear each other respectively, the awl chamber of its stator is respectively different taperings with the cone of rotor, thereby between the feed end stator of bistrique and rotor, form the certain included angle gap, utilize this gap coarse fodder particle of nipping, and relatively rotating along with rotor and stator, the minimum clearance place that the coarse fodder particle is ground gradually cooperate with rotor into stator is broken into fine particles with its grounds travel.In the process that material is pulverized; the surface of stator and rotor also can be ground; the metal particle that comes off on stator and the rotor can enter into material; material is polluted; or purity is affected; especially bigger for the harm of pharmaceutical, foodstuff material, particularly when being crushed to 5 microns left and right sides, further pulverize very difficult.

Summary of the invention

The technical problems to be solved in the utility model is, problems such as energy consumption height, the efficient that overcomes above-mentioned prior art existence is low, purity is influenced, fineness is restricted provide a kind of output height, energy consumption air-flow circulation impeller low, pollution-free, that can carry out the nanoscale pulverizing to quicken pulverizer.

The utility model has a frame, cabinet and power set are housed on frame, its special character is, semiclosed impeller is housed in cabinet, constitute impeller and quicken reducing mechanism, the feeding end of cabinet is connected with separator respectively with discharge end, described separator has a separator, upper side at separator has a tangential feeding mouth, tangential feeding mouth is connected with the discharge end of cabinet by tube connector, the lower end of separator is connected with the feeding end of cabinet by tube connector, constitutes air-flow circulation piece-rate system.

Described semiclosed impeller level or vertical the setting are to satisfy different needs.

Advantage of the present utility model is:

1, adopt semiclosed impeller as reducing mechanism, material is carried out high-speed impact, the centrifugal air draught effect of impeller makes the directed acceleration of material, strike again on the inwall of cabinet and separator, make material carry out multiple irregular bump and friction, simultaneously at impeller and cabinet inwall, also frictional impact between the material, thereby grindability of the present utility model is strong, effective energy utilization rate height, and material can be crushed to nanoscale.

2, separator is installed on reducing mechanism, reducing mechanism is pulverized material, material is quickened, form the high velocity air that carries material, circular flow in separator, and in the process of operation, material is separated, to reach the ultra micro powder of pulverizing requirement and discharge from outlet, the material of Fen Suiing does not then reenter in the reducing mechanism, pulverizes once more, and circulation repeatedly, up to pulverizing fully.

3, in the process of pulverizing, impeller does not contact, does not grind with cabinet and other parts, and can determine the material of semiclosed impeller according to the difference of comminuting matter material, thereby, pollution-free to material, be particularly suitable for foodstuff, drug class or high-purity rare mineral matter material grinding.
