Abstract

The utility model relates to a current disintegrator, and a machine body (1) is composed of a cylinder. The front end of the machine body (1) is connected with an air inlet pipe (2). The interior of the middle section of the machine body (1) is provided a Laval nozzle (3). The exterior of the machine body is provided with a material feeding hopper (4). The rear end of the machine body (1) is provided with a material discharging pipe (5). The tail end of the machine body (1) is provided with a target head (7) which is controlled by a handle (6). One surface of the target head (7) contacted with current and materials is a filing toothed surface and forms an inclination angle from 120 DEG to 150 DEG with the impact direction of the current. The design of the utility model enhances a shearing function and increases the disintegrating efficiency.

Description

Airslide disintegrating mill

The utility model relates to material process equipment field, especially a kind of airslide disintegrating mill.

Material grinding is a common procedure in the middle of the industrial production, and material-pulverizing device commonly used has bruisher, ball mill, flour mill, airslide disintegrating mill etc.And airslide disintegrating mill has obtained more application owing to the little advantage of temperature rise in further pulverizing that is particularly suitable for micro powder granule and the crushing process at medical industry.But present airslide disintegrating mill is owing to the target head is that a simple plane exists the not high defective of crush efficiency, and is just lower as the sporoderm-broken rate to spore class micro mist.

The airslide disintegrating mill that provides a kind of crush efficiency high is provided the purpose of this utility model.

The purpose of this utility model realizes by following technical proposals.

Airslide disintegrating mill of the present utility model constitutes body (1) by a cylinder, the front end of body (1) taps into tracheae (2), the middle intersegmental part of body (1) is equipped with Laval nozzle (3), loading hopper (4) is equipped with in the outside, the posterior segment in Laval nozzle (3) is opened in the outlet of loading hopper (4), the back segment of body (1) is equipped with discharge nozzle (5), the end of body (1) is equipped with the target head (7) by handle (6) control, target head (7) is the topping face with the one side that air-flow contacts with material, and becomes 120 °～150 ° inclination angle with the gas shock direction.

In the such scheme, discharge nozzle (5) links to each other with multi-cyclone again.

Airslide disintegrating mill of the present utility model is when work, material places loading hopper (4), compressed air is entered in the body (1) by air inlet pipe (2), behind the leading portion steady pressure of body (1), Laval nozzle (3) by body (1) stage casing produces the high velocity air that is twice in the velocity of sound again, to enter the material acceleration of Laval nozzle (3) posterior segment by loading hopper (4), material runs foul of each other in accelerator and pulverizes, at last bump body (1) terminal have the target head (7) of topping face the time further shear and pulverize, material after the pulverizing enters discharge nozzle (5) with air-flow, particle diameter as required carries out shaping and classification in multi-cyclone again, collect micro mist up to standard, below standard meal returns, and proceeds in the airslide disintegrating mill to pulverize again.Regulating handle (6), adjustable target head (7) stretch into distance, can change the target head and the difform topping face of different angles according to the material needs, thus the dynamics that changes bump and shear.

Airslide disintegrating mill of the present utility model is applicable to crystallization or the amorphous synthetic or natural macromolecular material that is fine-powdered under the normal temperature, as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), ethylene-vinyl acetate copolymer (EVA), polyvinyl alcohol (PVA), cellulose, polyamide (PA), Merlon (PC), polyformaldehyde (POM), polyester (PET, PBT), fluoroplastics, polyacrylamide, Chinese caterpillar fungus, glossy ganoderma, konjaku etc.

Airslide disintegrating mill of the present utility model has been owing to increased the topping face than the flat target head of prior art, thereby increased a shear action, makes crush efficiency improve greatly.

Be described in further detail the utility model below in conjunction with accompanying drawing.

Figure one is the schematic diagram of the utility model embodiment.

Figure two is classification operation schematic flow sheets of the present utility model.

Among the figure one, body (1) is a cylindrical shape, and the front end of body (1) taps into tracheae (2).The leading portion of body (1) is the stable gas pressure section, and air gauge (8) is housed.Laval nozzle (3) is equipped with in its inside, stage casing of body (1), and loading hopper (4) is equipped with in its outside, and the posterior segment in Laval nozzle (3) is opened in the outlet of loading hopper (4).The back segment of body (1) is equipped with discharge nozzle (5).The end of body (1) is equipped with the target head (7) by handle (6) control, and target head (7) is the topping face with the one side that air-flow contacts with material, and becomes the inclination angle that can regulate with the gas shock direction in 120 °～150 ° scopes.Body is supported by support (9) and is fixing.

Among the figure two, discharge nozzle (5) links to each other with the charging aperture of shaping grader (10).Secondary air enters shaping grader (10) from air inlet (11), drive micro mist through one-level whirlwind (12), secondary whirlwind (13) and enter sack cleaner (14), collect mouth from the micro mist of shaping grader (10), one-level whirlwind (12), secondary whirlwind (13) and sack cleaner (14) and collect the micro mist of different-grain diameter scope respectively, product up to standard wherein get finished product through packing, it is broken that below standard product are then sent airslide disintegrating mill relaying continued powder back to, till up to standard.

Claims

1. airslide disintegrating mill, constitute body (1) by a cylinder, the front end of body (1) taps into tracheae (2), the middle intersegmental part of body (1) is equipped with Laval nozzle (3), loading hopper (4) is equipped with in the outside, the posterior segment in Laval nozzle (3) is opened in the outlet of loading hopper (4), the back segment of body (1) is equipped with discharge nozzle (5), the end of body (1) is equipped with the target head (7) by handle (6) control, it is characterized in that the one side that target head (7) and air-flow contact with material is the topping face, and become 120 °～150 ° inclination angle with the gas shock direction.
