Description
Technical field
The utility model relates to airslide disintegrating mill technical fields, are especially provided with the air-flow crushing of overbottom pressure bleeder
Machine.
Background technique
The working principle of airslide disintegrating mill is: compressed air (or inert gas) passes through Bearing score after filtration drying
Your nozzle at high speeds spurts into crushed zone, at the joint of multiply high pressure draught, material by impact several times, friction, shearing and
It crushes, smashed material moves to separated region with ascending air under blower draft effect, in high-speed rotating classification whirlpool
Under the powerful centrifugal force effect that wheel generates, make thickness feed separation, the fine grained for meeting granularity requirements enters rotation by grading wheel
Wind separator and deduster are collected, and coarse granule, which drops to crushed zone, to be continued to crush.
After crushed work stops, it is first shut off the gas circuit of compressed air, then makes residual voltage in crushed zone gradually
It reduces.However, the residual voltage at the beginning between section still can be maintained at a high value, material in crushed zone can be blown into
Gas circuit, when restarting airslide disintegrating mill, the material in gas circuit is sprayed from Laval nozzle high speed, will cause the tight of nozzle
Damage is refaced even to damage.
Summary of the invention
Technical problem to be solved in the utility model is to prevent the material in crushed zone as residual voltage is blown into gas circuit,
Abrasion of the material to nozzle when avoiding restarting.
In order to solve the above-mentioned technical problem, the utility model provides: a kind of air-flow powder being provided with overbottom pressure bleeder
Broken machine, comprising: along the cylinder that vertical axial direction extends, the lower part of the cylinder is crushed zone, and top is Disengagement zone
Domain；Tracheae at the crushed zone and a plurality of Laval nozzles are set, and the annulus trachealis is arranged around cylinder, the Bearing score
You are connected to the tracheae and cylinder by nozzle；Grading wheel and discharge port at the separated region are set；It is connected on the cylinder
Have overbottom pressure bleeder, the overbottom pressure bleeder includes relief tube, the connecting tube that is connected to the relief tube and cylinder and
Switch in the connecting tube is set.
Further, it can releasably be connected between the relief tube and connecting tube.
Further, multiple openings are offered on the relief tube, the opening is closed by strainer.
Further, the relief tube is in the form of a column, and is arranged side by side with the cylinder.
Further, described to be open towards cylinder.
Due to the adoption of the above technical solution, the utility model has the advantage that said flow pulverizer stops in work
After only, the first step is that the switch opened on overbottom pressure bleeder turns off later so that the residual voltage in crushed zone reduces rapidly
The gas circuit of compressed air.Therefore, the excessively high state of residual voltage in crushed zone is avoided, namely avoids material and is blown into gas
Road, the risk sprayed again from nozzle high speed later, avoid abrasion of the material to nozzle, and nozzle greatly improved uses the longevity
Life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the airslide disintegrating mill of one specific embodiment of the utility model.
It is as shown in the figure: 1, cylinder, 11, crushed zone, 12, separated region, 2, tracheae, 3, Laval nozzle, 4, grading wheel,
5, discharge port, 6, feed inlet, 7, overbottom pressure bleeder, 71, relief tube, 711, opening, 712, strainer, 72, connecting tube, 73, open
It closes.
Specific embodiment
The above objects, features, and advantages of the utility model in order to facilitate understanding, are illustrated below with reference to embodiment.It answers
Understand, these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.For these implementations
A variety of modifications of example will be apparent to those skilled in the art, the general principles defined herein,
It can be achieved in other embodiments without departing from the spirit or scope of the present utility model.
A kind of airslide disintegrating mill shown in Figure 1, comprising: along the cylinder 1 that vertical axial direction extends, the cylinder
The lower part of body 1 is crushed zone 11, and top is separated region 12；Tracheae 2 at the crushed zone 11 and a plurality of is set
Laval nozzle 3, the tracheae 2 arrange that the Laval nozzle 3 is connected to the tracheae 2 and cylinder 1 around cylinder 1；Setting exists
Grading wheel 4 and discharge port 5 at the separated region 12.Feed inlet 6 is additionally provided on cylinder 1, feed inlet 6 is usually located at separation
At region 12.
It is connected with overbottom pressure bleeder 7 on the cylinder 1, which includes relief tube 71, with the pressure release
The connecting tube 72 and the switch 73 being arranged in the connecting tube 72 that pipe 71 is connected to cylinder 1.It is opened up on the relief tube 71
There are multiple openings 711, the opening 711 is closed by strainer 712, therefore gas can be flowed out out of relief tube 71, and material quilt
Strainer 712 is retained in relief tube 71.It can releasably be connected between relief tube 71 and connecting tube 72, so that relief tube 71 can be with
It disassembles and carries out material and topple over and/or filter screen cleaning, improve the service life of relief tube 71.The relief tube 71 is in the form of a column,
It is arranged side by side with the cylinder 1, to save arrangement space.It is described to be open 711 towards cylinder 1, to avoid spraying on relief tube 71
The air-flow at place damages personnel, improves safety.
For said flow pulverizer, after crushed work stops, the first step is opening on overbottom pressure bleeder 7 to be opened
73 are closed, at this point, the residual voltage in crushed zone 11 reduces rapidly, second step is the gas circuit for closing compressed air.In the above process, keep away
The excessively high state of residual voltage in crushed zone 11 is exempted from, namely has avoided material and be blown into gas circuit, later again from nozzle high speed
The risk of ejection avoids abrasion of the material to nozzle, the service life of nozzle greatly improved.
