Description
Technical field
The utility model relates to pharmaceutical fields, in particular for a kind of spiral feed type air-flow crushing of pharmacy crushing
Machine.
Background technique
Fluidized bed airflow pulverizer working principle is that material is rushed using the air-flow of several nozzles of two dimension or three-dimensional setting
It hits collision, friction that energy and its flow expansion are seethed in fluidized bed suspension and generated to be crushed, and under negative pressure gas flow drive
The turbine type grading plant being arranged by top, fine powder are discharged that machine is outer to be trapped by cyclone separator and bag collector, coarse powder by
Gravitational settling, which returns to disintegrating area, to be continued to crush.Existing some airslide disintegrating mill noises are larger, and land occupation is big, and product granularity is larger
(such as target formula airslide disintegrating mill), energy consumption is higher.
Summary of the invention
The invention provides a kind of spiral feed type airslide disintegrating mill, including feeding device, feed bin, screw feeder fill paper
And grinding device, the feeding device include feed hopper and the inlet control valve on feed hopper；The bottom of the feed bin
Equipped with screw feeder, screw feeder is connected to the disintegrating area of grinding device bottom；The grinding device includes bottom disintegrating area
With the fluidised bed zones on top；Disintegrating area is connected to the work nozzle for protruding into grinding device inner wall.
Preferably, the quantity of the work nozzle is 3-7.
Preferably, the work nozzle is connected with compressed air unit to obtain pressure-air, the grinding device top
Portion is equipped with grader and discharge port.
Preferably, the discharge port is connected with cyclone separator and bag collector.
The utility model has the beneficial effects that structurally reasonable, low noise is taken up little area, and product fineness is high, narrow particle size distribution,
Low energy consumption (about can save energy 30% ~ 40% compared with flat air flow crusher), flow field diversification, and crush efficiency is high.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure, feeding device 1, feed bin 2, screw feeder 3, disintegrating area 4, work nozzle 5, fluidised bed zones 6, Judas-hole 7,
Grader 8, discharge port 9.
Specific embodiment
With reference to the accompanying drawing, by the following detailed description, to be more clearly understood that the above and other of the invention
Objects, features and advantages.Hereinafter, the preferred embodiment of the invention will be described in detail with reference to the accompanying drawings.
Such as figure, the utility model is given in a kind of spiral feed type airslide disintegrating mill, including feeding device 1, feed bin 2, spiral
Material dress paper and grinding device.
The feeding device 1 include feed hopper and the inlet control valve on feed hopper, material via feed hopper simultaneously
Enter feed bin 2 through inlet control valve control.
The bottom of the feed bin 2 is equipped with screw feeder 3, and screw feeder is connected to the disintegrating area 4 of grinding device bottom.Object
Material is fed in grinding device via screw feeder 3, and the grinding device inner cavity includes the fluidisation on bottom disintegrating area 4 and top
Bed area 6.Disintegrating area 4 is connected to the work nozzle 5 for protruding into grinding device inner wall, and the quantity of work nozzle 5 described herein is 3-7
A, the nozzle may be provided in same plane or Different Plane；The work nozzle 5 is connected with compressed air unit to obtain
Pressure-air is obtained, is equipped with grader 8 and discharge port at the top of the grinding device.
Gas shock energy and its flow expansion of the material through several work nozzles 5 are seethed in fluidized bed suspension in fluidized bed
Area 6, material generates collision by this, friction is crushed, and is divided under negative pressure gas flow drive by the grader 8 that top is arranged
Grade, fine powder are trapped via outside discharge port discharge machine by cyclone separator and bag collector, and coarse powder is returned by gravitational settling and crushed
Continue to crush in area 4.
Herein preferably, for the ease of the situation in observation grinding device, grinding device body side is equipped with Judas-hole 7.
Although the preferred embodiment of the invention is disclosed for illustrative purpose, those skilled in the art
Member should be appreciated that under the premise of the scope and spirit created without departing substantially from appended claims present invention disclosed, various
Modification, increase and adulterium are all possible, it is noted that upper under the premise of without departing substantially from the invention scope and spirit
Stating various modifications, increase and altering should all cover within the interest field of the invention.
