Description
Technical field
The utility model relates to a kind of grinding machine, especially relates to the dynamic powder selection device of a kind of grinding machine internal combustion.
Background technology
The dynamic powder selection device of grinding machine internal combustion is the important component part of grinding machine; Its effect is to utilize the dynamic wind of the dynamic powder selection device ejection of internal combustion that the material on the mill is carried out sorting; Qualified material is selected; Defective material continues to stay mill mills, and prevents that qualified material from milling again to cause material to cross to pulverize and form waste product.At present, the dynamic powder selection device of no internal combustion in the common grinding machine, material are moved outside mill by the centrifugal force that only depends on mill to rotate after milling on mill, do not have the powder process of selecting.Its problem one is because above-mentioned material after being milled on the mill, is still milled when qualified material leaves mill under centrifugal action once more or repeatedly, is easy to generate a large amount of waste products; Its problem two is to lean on the centrifugal force of mill rotation toward sending material outside, and efficient is lower, so and lower because of being easy to generate waste product production efficiency.The method of head it off all concentrates on rotating speed that changes grinding machine or the measures such as shape that change mill now; Though these methods can reduce percent defective and the production efficiency that improves grinding machine to a certain extent; But but can't change the higher and production capacity phenomenon on the low side of percent defective; Increased manufacturing, installation difficulty and investment of devices simultaneously, higher to the electrical control requirement, also can bring some other unpredictalbe problems.
The utility model content
In order to solve the technical problem that above-mentioned prior art exists, the utility model provides a kind of grinding machine internal combustion dynamic powder selection device, and this device has been realized the yield rate of grinding machine and improved the production efficiency of grinding machine.
The technical scheme that adopts is:
The dynamic powder selection device of grinding machine internal combustion comprises support body, nozzle ring, lower seal case, mill, abrasive disk seat, conical lid, it is characterized in that described nozzle ring is fixed on support body inside and concentric; The lower seal case is fixed on support body interior lower end and concentric; The lower seal box cavity is concentric and form two annular gaps with the abrasive disk seat lower end, and perforate communicates with the lower seal case on abrasive disk seat center cavity and the sidewall, and mill is fixed on abrasive disk seat upper end and concentric with it; It is also concentric with it that conical lid is fixed on the abrasive disk seat upper end; Conical lid is in the inside of mill simultaneously, and conical lid is inner to communicate conical lid band internal combustion nozzle with the abrasive disk seat center cavity; Nozzle therefrom mind-set is jetted outward, and nozzle ring is in the outside of mill and concentric with it.
Operation principle: support body and lower seal case are all fixing; After interior winding-up wind gets into the lower seal case; Perforate through on the abrasive disk seat sidewall enters into the abrasive disk seat center cavity, and interior winding-up wind directly gets into conical lid inside through the abrasive disk seat center cavity again, through the internal combustion nozzle on the conical lid; Preliminary sorting is directly carried out with the qualified material on the mill in interior winding-up wind ejection back; Qualified material through interior winding-up selection by winnowing goes out is carried out sorting once more through the main road wind of nozzle ring ejection again, and qualified material is taken out of grinding machine by main road wind fully, and defective material is delivered to mill once more and milled until qualified.Abrasive disk seat rotates in the work; Because the lower seal case is concentric and form two annular gaps with the abrasive disk seat lower end; Interior winding-up wind can directly get in the abrasive disk seat through the perforate on the abrasive disk seat sidewall in fixing lower seal case; Thereby winding-up wind is through the winding-up effect of conical lid in can realizing, interior winding-up wind can carry out sorting and outside boosting to the material on the mill.
The utility model has solved because above-mentioned material after being milled on the mill, is still milled when qualified material leaves mill under centrifugal action once more or repeatedly, is easy to generate the problem of a large amount of waste products; Also solved simultaneously by the centrifugal force of mill rotation is past and sent material outside, efficient is lower, so and because of being easy to generate the lower problem of waste product production efficiency.The utility model in the course of the work, utilizes the nozzle on the conical lid that interior winding-up wind is pushed mill through winding-up wind in increasing; Qualified material in the mill is selected from bank by interior winding-up wind, has avoided qualified material once more by pan-milling, has reduced the percent defective of material; Material has promoted material and outside mill, has moved under the blowing of interior winding-up wind simultaneously, has improved production efficiency; Because abrasive disk seat rotates at work always, so the pneumatic attitude of interior winding-up of conical lid ejection has not only solved problem; Also saved a large amount of investments, and simple in structure and be a dynamic powder selection device of cocksure grinding machine internal combustion.
