Description
Technical field
The utility model relates to a kind of crushing system with the various material of ultra-fine grinding and dispersing nanometer powder reuniting particle.
Technical background
In prior art, airflow milling crushing technology is conventional superfine technique, is widely used in the ultra-fine grinding of nonmetallic mineral, nano-powder and industrial chemicals.
Its operation principle is that material charger evenly feeds in raw material to airflow milling charging aperture, and magazine-less system afterbody is provided with air nozzle, is connected and ejects compressed air with compressed air.According to venturi injection principle, in charging aperture, material is compressed suction feed introduction, and is mixed to form with compressed air the crushing chamber that airflow milling is spurted in logistics.After logistics is entered crushing chamber by injection, be subject to being located at crushing chamber surrounding and pulverize repeatedly repeatedly the clashing into of the supersonic airstream that nozzle tangentially sprays, shear, and collide with the chamber wall of crushing chamber and upper and lower covers, rub, reach the object of pulverizing.In crushing process, the particle of different fineness, in swirling eddy, produce different centrifugal force, coarse granule is thrown toward periphery because suffered centrifugal force is greater than the active force of centripetal air-flow, continues to pulverize; By exhaust airstream band to discharging opening, entering collector by pipeline carries out gas solid separation because the active force of centripetal air-flow is greater than centrifugal force for the particle of qualified fineness, thus obtains finished product.Tail gas is drained through filter collector again.
Because of dried Nano metal powder exist larger powder ball, such large powder ball easily blocks airflow milling charging aperture affects charging, and if it directly enters in air-flow mill chamber, can not finally being affected product dispersiveness by disperseing completely, causing product defective.
Utility model content
The utility model object is the efficient pulverizing system providing a kind of automation, solves airflow milling charging aperture and is easily caused the problem of regurgitating by foreign matter or big particle blocking, provides stable feed system to realize balanced feeding in raw material and ensure that production stability.
A kind of efficient pulverizing system, comprises charger, magazine-less system, air nozzle, airflow milling and tail gas collection system, it is characterized in that: described charger is oscillating batch charger, and oscillating batch charger discharging opening is provided with filter.
Described oscillating batch charger controllable silicon halfwave rectifier is powered, and realizes the centralized Control of production process and automatically controls.
Described filter adopts lattice-shaped structure, sieves material.
Described tail gas collection system adopts two-stage filter, filters to reach the object that purifies air to tail gas, and system, by a part of tail gas supply workshop after purification, is supplemented and caused production scene lack of air because venturi injection causes and present negative pressure appearance.
The utility model beneficial effect:
The utility model passes through the lattice-shaped filter increasing certain size at oscillating batch charger discharging end, to remove the large powder ball of part in metal powder.Adopt new-type oscillating batch charger to realize stable charging, ensure that production stability.This system also carries out cascade filtration, a part of qualified discharge to the air of discharge, recycling in another part air circulating vehicle, has and supplements air to either inside and reduce wetness action.

Detailed description of the invention
Below in conjunction with Fig. 1, the utility model is described further.
The utility model is the crushing system of the various material of a kind of ultra-fine grinding and dispersing nanometer powder reuniting particle, comprise: hopper 1, air-introduced machine 9, filter collector 10, filter collector 11, muffler 12, evacuated tube 13, filter 3 to be welded on oscillating batch charger on 2, air nozzle 4 is installed in magazine-less system 5, it is inner that crushing chamber 7 is positioned at airflow milling 6, and airflow milling discharging opening is connected on dust-precipitator 8 by pipeline.
Working method is that material is evenly fed in raw material to airflow milling 6 charging aperture from hopper by oscillating batch charger 2, and in charging aperture, material is compressed suction feed introduction, and is mixed to form with compressed air the crushing chamber 7 that airflow milling is spurted in logistics.After logistics is entered crushing chamber 7 by injection, be subject to being located at crushing chamber surrounding and pulverize repeatedly repeatedly the clashing into of the supersonic airstream that nozzle tangentially sprays, shear, and collide with the chamber wall of crushing chamber 7 and upper and lower covers, rub, reach the object of pulverizing.By exhaust airstream band to discharging opening, entering dust-precipitator by pipeline carries out gas solid separation because the active force of centripetal air-flow is greater than centrifugal force for the particle of qualified fineness, thus obtains finished product.Tail gas is again through filter collector dedusting emptying.
Oscillating batch charger 2 adopts Near resonance oscillating principle, powers by controllable silicon halfwave rectifier, in use infinitely can regulate feeding coal, achieves the centralized Control of production process and automatically controls.It also has the plurality of advantages such as volume is little, lightweight, operating cost is low.
Oscillating batch charger 2 feed opening adopts lattice-shaped structure to make, and grid size can make according to comminuting matter granular size.Have and sieving actoion is carried out to material, foreign matter or big particle are separated in trash receptacle, prevent its blocking airflow milling charging aperture, and to product, there is certain impurity removal function.
Native system adopts two-stage filter to exhaust collection, and secondary filter can adopt PE-M bag filter or clapboard type filter to tail gas filtering to reach the object that purifies air.
