Description
Technical field
The invention belongs to airslide disintegrating mill construction applications, be specifically related to a kind of airslide disintegrating mill nozzle air inlet structure-improved.
Background technology
All by by compressed air during airslide disintegrating mill work, the disintegrating area of pulverizing cavity is spurted into through nozzle at high speeds, at the joint place material of multiply high pressure draught by impact several times, friction, shearing and pulverizing, material after pulverizing moves to graded region with ascending air, under the air-flow centripetal force effect that powerful centrifugal force and the blower negative pressure of the generation of grading wheel High Rotation Speed produce, thickness material realizes being separated, the fine grained meeting granularity requirements passes through grading wheel, collected discharging by rear road whirlwind wind from device, pulse dust collector, 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 supplies by gas distribution plate distribution the nozzle be located in airslide disintegrating mill afterwards, usually, gas distribution plate ringwise, forms the annular space of an airtight connection in gas distribution plate; The nozzle be communicated with gas distribution plate is provided with four, is uniformly distributed in the periphery of gas distribution plate, leaves gap between two relative nozzles.This nozzle air intake structure, when the air pressure of compressed air source and air consumption certain, nozzle diameter is relatively little, and it is far away apart from pulverizing barrel, be unfavorable for producing larger pulverizing impulse force, material near barrel is also not easy to enter in jet-stream wind, thus have impact on 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, because gas distribution plate is usual ringwise, surround whole pulverizing cylindrical shell, therefore, besel is forced to stagger up and down with gas distribution plate usually, thus sight line is observed in impact, is unfavorable for observing.
Summary of the invention
In order to solve the problem, the invention provides a kind of airslide disintegrating mill nozzle air inlet structure-improved, by by the structural improvement of traditional annular gas distribution plate be there is breach and breach end close annular gas distribution plate, reduce the nozzle quantity be communicated with it, three are changed into by four, under equal air consumption, nozzle can amplify, and more near pulverizing cylinder inboard wall, the effective range of nozzle can be increased, obtain larger impulsive force, the material by barrel also can enter jet-stream wind smoothly, improves 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, thus reach the object of being convenient to observe and operate.
The present invention in order to the technical scheme solving its technical problem and adopt is:
A kind of airslide disintegrating mill nozzle air inlet structure-improved, 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, a distribution space is formed in described gas distribution plate, described distribution space is communicated with external compressed air source by air inlet pipe, and described distribution space is communicated with several nozzles external by air inlet pipe.
As a further improvement on the present invention, be provided with three described nozzles, three described nozzles are communicated with external described distribution space also uniformly at intervals in the circumference of described gas distribution plate.
As a further improvement on the present invention, 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 a further improvement on the present invention, described pulverizing cylindrical shell is provided with besel, and described besel is positioned at described breach.
The invention has the beneficial effects as follows: airslide disintegrating mill nozzle air inlet structure-improved of the present invention has following advantage:
One, present invention improves over the structure of gas distribution plate: adopt there is breach and breach end close annular gas distribution plate structure, preferably, adopt there is breach and breach end close annular gas distribution plate structure, compared with traditional annular gas distribution plate structure, when Compressed Gas air pressure and air consumption certain, the more close of designs of nozzles can be pulverized cylinder inboard wall, the bore of nozzle is strengthened, thus the effective range of nozzle can be increased, also jet-stream wind can be entered smoothly by barrel logistics, obtain larger impulsive force, improve crush efficiency and the output of whole airslide disintegrating mill.
Two, the present invention makes traditional four nozzles into three nozzles, and the external place of the connection of three nozzles is uniformly at intervals in the circumference of gas distribution plate, preferably, be designed to wherein two nozzles and be communicated with external distribution space near breach, 3rd nozzle is equidistantly positioned between the two and is communicated with external distribution space, three nozzles can be made to obtain and better spray air pressure.
Three, present invention improves over the position of besel: be designed to there is breach by gas distribution plate and the airtight annular gas distribution plate structure of breach end, the space that gas distribution plate occupies can be saved, thus can by the gap position of besel design at gas distribution plate, like this, the object of being convenient to observe and operate can be reached.
