Background technology
Airslide disintegrating mill when work is all by by compressed air, enter to pulverize the disintegrating area of cavity through nozzle high velocity jet, at the joint place of multiply high pressure draught, material is repeatedly collided, is rubbed, is sheared and pulverized, material after pulverizing moves to graded region with ascending air, under the air-flow centripetal force effect that the powerful centrifugal force producing at grading wheel High Rotation Speed and blower negative pressure produce, thickness material is realized and being separated, the fine grained that meets granularity requirements passes through grading wheel, Bei Hou road whirlwind wind is collected discharging from device, pulse dust collector, and coarse granule returns to disintegrating area to be continued to pulverize.
In prior art, the pulverizing cylindrical shell of airslide disintegrating mill is fixed in frame, pulverizing cylindrical shell bottom is disintegrating area, outside disintegrating area, there is gas distribution plate, gas distribution plate is communicated with external compressed air source by air inlet pipe, and compressed air is supplied with the nozzle of being located in airslide disintegrating mill after distributing by gas distribution plate, conventionally, gas distribution plate ringwise, forms the annular space of an airtight connection in gas distribution plate; The nozzle being communicated with gas distribution plate is provided with four, is uniformly distributed in the periphery of gas distribution plate, between two relative nozzles, leaves gap.This nozzle air intake structure, in the case of the air pressure of compressed air source and air consumption certain, nozzle diameter is relatively little, and barrel is far away apart from pulverizing, be unfavorable for producing larger pulverizing impulse force, material near barrel is also not easy to enter in jet-stream wind, thereby has affected crush efficiency and the output of whole airslide disintegrating mill.In addition, the disintegrating area of pulverizing cylindrical shell is typically provided with besel, for observing crushing process and state, due to gas distribution plate conventionally ringwise, surround whole pulverizing cylindrical shell, therefore, besel is forced to stagger up and down with gas distribution plate conventionally, thereby sight line is observed in impact, is unfavorable for observing.
Summary of the invention
In order to address the above problem, the utility model provides a kind of airslide disintegrating mill nozzle air inlet structure-improved, by by the structural improvement of traditional annular gas distribution plate being the annular gas distribution plate with breach and the sealing of breach end, reduce the nozzle quantity being communicated with it, change three into by four, equating under air consumption, nozzle can amplify, and more near pulverizing cylinder inboard wall, can increase the effective range of nozzle, obtain larger impulsive force, also can enter smoothly jet-stream wind by the material of barrel, improved crush efficiency and the output of whole airslide disintegrating mill.And said structure is easy to process, save the space that gas distribution plate occupies, be conducive to the setting of besel, thereby reach the object of being convenient to observation and operation.
The utility model for the technical scheme that solves its technical problem and adopt is:
Nozzle air inlet structure-improved for a kind of airslide disintegrating mill, comprise and pulverize cylindrical shell and tool annular gas distribution plate jaggy, described gas distribution plate is installed in the periphery of described pulverizing cylindrical shell, the breach two ends of described gas distribution plate are airtight, in described gas distribution plate, form a distribution space, described distribution space is communicated with external compressed air source by air inlet pipe, and described distribution space is communicated with external several nozzles by air inlet pipe.
As further improvement of the utility model, be provided with three described nozzles, three described nozzles be communicated with external described distribution space and uniformly at intervals in described gas distribution plate circumferentially.
As further improvement of the utility model, wherein, two described nozzles are communicated with external described distribution space near described breach, and the 3rd described nozzle is equidistantly positioned between the two and is communicated with external described distribution space.
As further improvement of the utility model, described pulverizing cylindrical shell is provided with besel, and described besel is positioned at described breach.
The beneficial effects of the utility model are: airslide disintegrating mill of the present utility model has following advantage with nozzle air inlet structure-improved:
One, the utility model has improved the structure of gas distribution plate: adopt the annular gas distribution plate structure with breach and the sealing of breach end, preferably, employing has the annular gas distribution plate structure of breach and the sealing of breach end, compared with traditional annular gas distribution plate structure, at Compressed Gas air pressure and air consumption certain in the situation that, can be by the more close cylinder inboard wall of pulverizing of designs of nozzles, the bore of nozzle is strengthened, thereby can increase the effective range of nozzle, also can enter smoothly jet-stream wind by barrel logistics, obtain larger impulsive force, improve crush efficiency and the output of whole airslide disintegrating mill.
Two, the utility model makes four traditional nozzles into three nozzles, and the external place of the connection of three nozzles uniformly at intervals gas distribution plate circumferentially, preferably, be designed to wherein two nozzles and be communicated with external distribution space near breach, the 3rd nozzle is equidistantly positioned between the two and is communicated with external distribution space, can make three nozzles obtain the better air pressure that sprays.
Three, the utility model has improved the position of besel: gas distribution plate is designed to have breach and the airtight annular gas distribution plate structure of breach end, can save the space that gas distribution plate occupies, thereby besel can be designed to the gap position at gas distribution plate, like this, can reach the object of being convenient to observation and operation.
