Abstract
The utility model discloses an automatic negative pressure control regulating system for fluid energy milling of a fluidized bed. The automatic negative pressure control regulating system comprises a fluid energy milling machine and a cyclone segregating machine which are mutually connected, and the fluid energy milling machine is sequentially connected with a freezer dryer, an air storage tank and an air compressor. The cyclone segregating machine is sequentially connected with a dust collector and a high pressure fan. The automatic negative pressure control regulating system is formed by the high pressure fan and the dust collector, and negative pressure can be adjusted at any time according to different requirements of product granularity. The automatic negative pressure control regulating system is applicable to superfine grinding of a plurality of materials, does not need adding any auxiliary electronic control system, and is simple in structure and high in production efficiency.
Description
Technical field
The utility model relates to a kind of fluidized bed airflow pulverizing and controls to adjust system with automatic negative-pressure, belongs to the mechanotronics field.
Background technology
Fluidized bed air flow crusher is a kind of equipment of realizing dry type material ultramicro grinding with high velocity air; It is formed by pulverizing nozzle, classification rotor, screw feeder etc.; Workflow as the one of which is: material gets into pulverizing chamber through screw feeder, presses the superonic flow nozzzle of fast air through particular arrangement to the pulverizing chamber high velocity jet, and material quickens in the superonic flow nozzzle jet; And, reach pulverizing in the repeated stock of nozzle intersection, collision.Got into grading room by comminuting matter with ascending air; Because classification is changeed from rotation at a high speed, particle had both received the centrifugal force that the classification rotor produces, and received the centripetal force that the air-flow viscous effect produces again; When particle receives centrifugal force greater than centripetal force; Be that the directly above corase particles of classification returns pulverizing chamber continuation impact comminution, the fine particle below the classification footpath gets into cyclone separator, trap collection with air-flow, and gas is discharged by air-introduced machine.
A kind of good equipment as ultra-fine grinding; Airslide disintegrating mill often is designed and is introduced in the different ultramicro grinding systems, because material concentration and charging rate that this equipment can not be consistent through Artificial Control need to get involved automatic control equipment usually; Cost is higher; And set through automatic control equipment and to be difficult for after each parameter revising, can not adjust charging rate and material concentration at any time, versatility is not extensive.
Summary of the invention
The utility model provides a kind of fluidized bed airflow to pulverize and controls to adjust system with automatic negative-pressure, regulates material concentration and charging rate at any time, realizes regulating automatically through negative pressure control, and versatility is extensive.
The utility model is to realize through following technical scheme:
A kind of fluidized bed airflow is pulverized and is controlled to adjust system with automatic negative-pressure, comprises interconnected airslide disintegrating mill and cyclopneumatic separator, and said airslide disintegrating mill connects freeze drier, air accumulator and air compressor successively; Said cyclopneumatic separator connects dust arrester and high pressure positive blower successively.
As a kind of preferred implementation of the utility model, said airslide disintegrating mill is a fluidized bed air flow crusher.
As a kind of preferred implementation of the utility model, a control valve is installed between said high pressure positive blower and the dust arrester.
As a kind of preferred implementation of the utility model, a control valve is installed between said dust arrester and the cyclopneumatic separator.
The beneficial effect of the utility model is:
1, adjusts negative pressure at any time, control simultaneously by the charging rate of comminuted material and material concentration, quantitatively control appliance;
2, the requirement of different material and change of granularity can both obtain effectively satisfying and realizing easily, improves the versatility of equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
Like Fig. 1; It is the structural representation of the utility model; Be that a kind of fluidized bed airflow pulverizing controls to adjust system with automatic negative-pressure, comprise interconnected airslide disintegrating mill 4 and cyclopneumatic separator 5, by knowing among the figure; Airslide disintegrating mill 4 also connects freeze drier 3, air accumulator 2 and air compressor 1 successively and forms the air-flow disintegrating apparatus, control comminuting matter concentration; Said cyclopneumatic separator 5 connects dust arrester 6 and high pressure positive blower 7 successively.
Wherein airslide disintegrating mill is a fluidized bed air flow crusher, and a control valve 8 is installed between high pressure positive blower and the dust arrester.In addition, control valve 8 can also be installed between dust arrester and the cyclopneumatic separator.The utility model is regulated high pressure positive blower 7 and the exhausting negative pressure system that dust arrester 6 constitutes through control valve, can frequently adjust at any time according to different comminuting matters and product granularity requirement, can quantitatively control.Need not to increase any auxiliary electrical sub-control system, the requirement of different material and change of granularity can both obtain effectively satisfying and realizing easily.
