Abstract

The present invention relates to a target-absorbing superfine crusher with accelerating rotation, which solves the problems of high energy consumption, low efficiency, affected purity, etc. existing in the prior art. The present invention is provided with a machine frame on which a machine box and a power device are arranged. The present invention is characterized in that a semi-sealed target wheel is arranged in the machine box so as to form a rotary target-absorbing superfine crusher. A material feeding end of the machine box is provided with a shaped communicating pipe of which the front end is provided with a rotary target-absorbing superfine accelerator which is provided with a machine frame. A power device and a machine box in which a semi-sealed target wheel is arranged are arranged on the machine frame. The present invention has the advantages that the rotary target-absorbing superfine accelerator not only increases impact time of materials, but also accelerates the initial speed of material movements; when rotates and impacts materials, the semi-sealed target wheel completely avoid the wind reflection of high speed airflow impacting on a target surface because of the function of centrifugal absorbed wind; therefore, the present invention with strong crushing capability can crush materials into nanometer states.

Description

Quicken rotary ultrafine crusher

Technical field

The invention belongs to a kind of disintegrating apparatus, the rotary ultrafine crusher of particularly a kind of acceleration.

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, and the metal particle that comes off on stator and the rotor can enter into material, and material is polluted, or purity is affected, and is bigger for pharmaceutical, the harm of foodstuff material especially.

Summary of the invention

The technical problem to be solved in the present invention is, overcomes problems such as energy consumption height, efficient that above-mentioned prior art exists are low, purity is influenced, provide a kind of output height, energy consumption low, pollution-free, can carry out the rotary ultrafine crusher of acceleration that nanoscale is pulverized.

The present invention has a frame, cabinet and power set are housed on frame, its special character is, semiclosed impeller is housed in cabinet, center at cabinet, the side of opening wide of semiclosed impeller has a feeding mouth, constitute rotary reducing mechanism, a center line and the perpendicular mozzle of semiclosed impeller are installed on the feeding mouth of cabinet, a special-shaped communicating pipe is installed on the mozzle, make material directly enter semiclosed impeller, front end in communicating pipe also is equipped with rotary accelerator, described rotary accelerator has a frame, and cabinet and power set are housed on frame, and semiclosed impeller is housed in cabinet, utilize rotary accelerator material is pulverized and to be quickened, utilize rotary reducing mechanism that material is further pulverized again.

The invention has the advantages that:

1, at the feeding end of rotary reducing mechanism rotary accelerator is installed, material has just begun pulverizing before entering rotary reducing mechanism, both increased the number of times of material collision, also improved the movement velocity of material, simultaneously, communicating pipe rotary accelerator is connected with rotary reducing mechanism with abnormity with mozzle, wind is not obstructed, do not turn round, acceleration travels forward, high velocity air carries on the blade that material at first impinges upon semiclosed impeller in the rotary accelerator cabinet, the centrifugal air draught effect of blade makes the directed acceleration of material, strike again on the inwall of cabinet, also frictional impact between the material, and with high velocity air by being directly incident on mozzle and communicating pipe on the rotary reducing mechanism, semiclosed impeller on the rotary reducing mechanism is when the rotating percussion material, because the effect of centrifugal air draught, the wind of having avoided high velocity air to impinge upon on the blade face fully reflects, thereby the material high-speed motion is impinged upon on the blade, in being injected into the crushing process of semiclosed impeller, material is clashed at base plate place, impeller axle center earlier, the bump back enters between blade with high velocity air, because the centrifugal action of blade is quickened material once more, material with cabinet outer wall and high-speed motion bumps against then, material carries out multiple irregular bump and friction at blade edge and cabinet inwall like this, thereby grindability of the present invention is strong, effective energy utilization rate height, and material can be crushed to nanoscale.

2, adopt semiclosed impeller as crushing part, in the process of pulverizing, semiclosed impeller does not contact, does not grind with shell and other parts, in crushing process, material do not pushed, shears, grinds, cuts mechanisms such as stranding, turbulence, 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.
