A feeding opening is arranged on the middle part of the cover plate. The utility model has the advantage of high efficiency. The utility model is suitable for grinding soft and hard materials with various hardness grades.
Description
The utility model relates to a kind of size reduction machinery, particularly be a kind of airslide disintegrating mill.
Chinese patent notification number CN2181993Y discloses a kind of " spiral-flow type air flow crushing device ", its formation comprises vertically upward a columniform pulverizer, a drive unit and a grading plant that is installed in swirling eddy wherein, an air current circulation and a dust arrester installation.Dust arrester installation links to each other with grading plant in the crushing chamber by a transfer tube.Its drive unit is made of rotating disk, the backplate that radially is fixed on the aerofoil on the rotating disk and is fixed on rotating disk outer rim place along rotating disk.Rotate under the driving of motor by rotating disk, drive aerofoil driving air-flow and in crushing chamber, form swirling eddy, the grind materials for the treatment of in the chamber is collided to reach the purpose of pulverizing in this swirling eddy mutually.The shortcoming of this reducing mechanism is that its cylindrical crushing chamber only plays a part to form swirling eddy, do not produce collision with material, thereby its crush efficiency is low, and fineness of grind is also limited.
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of crush efficiency height is provided, and fineness of grind can reach the centrifugal ultra tiny autogenous tumbling mill of vertical circulation of submicron order.
The formation that realizes the centrifugal ultra tiny autogenous tumbling mill of vertical circulation of the utility model purpose comprises that one is provided with the pulverizing chamber of charging aperture, a classification mechanism that is horizontally set on the rotating disk that has aerofoil in the pulverizing chamber and is located at the pulverizing chamber top, the inwall of described pulverizing chamber is an inner concavity inwall, the aerofoil of described rotating disk is provided with a cover plate, has a feeding mouth at the middle part of cover plate.During work, the rotation of driven by motor rotating disk, in pulverizing chamber, form spiral air-flow, treat the feeding mouth that grind materials from rotating disk cover plate be provided with next from the charging aperture of pulverizing chamber enters the rotating disk, under action of centrifugal force, collide from throwing away rotating disk at the inwall of pulverizing chamber and realize once pulverizing by the passage that constitutes between blade, enter thereupon and do continuous gas-solid ternary screw in the spiral air flow in the pulverizing chamber, compound action such as the material formula that is subjected to each other catching up with is impacted, collision, friction shearings, the flutter of gas-solid dither and realize the autogenous grinding pulverizing.Material after the pulverizing enters under the effect of spiral air-flow in the classification mechanism above the pulverizing chamber, and the particle that will not meet granularity requirements by classification mechanism is told and fallen back to pulverizing chamber and continue grinding.Qualified products then externally enter under the extracting effect of blower fan collect in the gatherer product.
For strengthening the intensity of formed spiral air flow, can on the bottom surface of rotating disk, set up some arc shaped blades that rotating disk turns to that bend towards.
The longitudinal cross-section of described arc shaped blade is designed to the shape of the right-angled trapezium shape of narrow inner width outward, formed air-flow better effects if.
Between pulverizing chamber and classification mechanism, can be provided with one and impact discrete rectifier, the material after the pulverizing is fully disperseed, form the gas-solid laminar flow and enter in the classification mechanism, simultaneously the coarse granule material be dammed to get off, fall back to pulverizing chamber and participate in collision again and pulverize.Help further improving crush efficiency.
For improving the uniformity that material enters rotating disk, a crown material distributing cap can be set in the centre of rotating disk.
In the outer end of described aerofoil a block of stretching on passage is set, can plays when initial material is thrown away and be lived and reside in this place's formation material from bed course, reduce the wearing and tearing of aerofoil, also can play cushioning effect on the other hand by shelves.
Below the rotating disk of pulverizing chamber, but a wind gathering dish and an air inlet that has air register are set, can play the effect of regulating the air-flow size.
Described classification mechanism can be horizontal setting.Also can be vertical setting.
In the periphery of pulverizing chamber a water-cooled ring set can be set, so that the temperature of pulverizing chamber remains under the normal condition of work.
The utility model advantage compared with prior art is efficient height, energy savings; And simple and compact for structure, vibrate for a short time, highly versatile is applicable to the crisp rigid material of pulverizing various hardness leveles.
Provide embodiment below in conjunction with accompanying drawing.But content of the present utility model is not limited in this embodiment.
Fig. 1 is a structural representation of the present utility model
Fig. 2 be among Fig. 1 rotating disk overlook enlarged drawing
Fig. 3 is the upward view of Fig. 2
Fig. 4 is the structural representation of horizontal classification mechanism
As shown in Figure 1, the inwall 2 of pulverizing chamber 1 is the inwall of an inner concavity.This inwall can be various cambered surfaces, or is constituted by the curved section of different curvature radius.Rotating disk 3 is located in the pulverizing chamber 1, joins with motor 25 by soft shaft coupling 24 and main shaft 27, and motor 25 is installed on the support 13.Cover plate 4 lids are connected on the aerofoil 5, constitute the logical material 6 of material, and referring to Fig. 2, Fig. 3,23 is block among the figure.Have feeding mouth 7 at the middle part of cover plate 4.8 tops that are connected on feeding mouth 7 by a lower oblique tube 9 of the charging aperture of pulverizing chamber.For guaranteeing that material enters rotating disk from feeding mouth 7, be provided with a funnelform feed back dish 10.The middle part of rotating disk is provided with a crown material distributing cap 26.For increasing the intensity of the spiral air flow that in pulverizing chamber, forms, on the bottom surface of rotating disk 3, also have additional some arc-like sheets 11 that bend towards the rotating disk steering direction.The longitudinal cross-section of this arc shaped blade 11 can be designed to outer narrow inner width the right-angled trapezium shape, better effects if.Classification mechanism 14 can be continued to use the place, top position that the version that has grader now is arranged on pulverizing chamber.Join with motor 17 by power transmission shaft 15 and belt wheel transmission mechanism 16.What present embodiment provided is a kind of form of vertical setting.Also can adopt horizontal form setting as shown in Figure 4.Impacting discrete rectifier 18 is located between pulverizing chamber 1 and the classification mechanism 14.
