Description
Technical field
The utility model relates to a kind of grinder, is specifically related to a kind of Raymond roller mill of abrasive micropowder.
Background technology
The Raymond mill milling apparatus can be used for the production of powders such as carborundum; This grinder comprises parts such as grinding roller, bull ring and perching knife; Perching knife comprises perching knife panel and perching knife side plate washer, and its operation principle is: the grinding roller that is driven in the rotating shaft by variable-frequency motor makes its generation centrifugal force press to bull ring, thereby forms an abrasive power; When grinding roller when bull ring moves in a circle with self spinning motion, this abrasive power is with improved grinding to required granularity; Material grinds via under the acting in conjunction of perching knife panel and perching knife side plate washer material being taken up and shed between bull ring and grinding roller.Material after the grinding takes up through grinding cavity and graded chamber via the air-flow of Raymond mill inferior part of the cylinder block air inlet; After the classifying turbine screening; Granularity meets the requirements of particle can get into next step classification through classifying turbine, does not reach returning in the grinding cavity of granularity requirements and does further grinding.
The problem that existing similar grinder exists is:
The part that the grinding cavity of existing Raymond mill links to each other with graded chamber becomes the right angle of 90 degree, design unreasonablely, has hindered and has ground flowing of cavity internal gas flow, the part particle that reaches granularity requirements stopped and by grinding once more, has caused excessive pulverizing.Therefore, need improve, so that flowing of air-flow do not caused obstruction, thereby reduce excessive crushing quantity, improve yield rate the shape of cavity discharging opening.The design of existing perching knife structure discharge end is also unreasonable, and quality is shed, pulverized to material and crush efficiency has all produced influence.So, also need improve the structure of perching knife, be optimized with the face of the shedding decentralization of material is dished out direction and material, pulverize quality and crush efficiency thereby improve.
The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art; Optimal design through the discharging airflow pipeline; With excessive pulverizing and the raising yield rate that reduces material; The direction of material being dished out through perching knife simultaneously and the face of the shedding decentralization optimization of material are to improve grinding efficiency and Grinding Quality.
For realizing above-mentioned purpose, the technical scheme of the utility model has provided a kind of Raymond roller mill, and said grinder comprises grinding roller and the bull ring that cooperatively interacts and be used for grinding material; Lower end at said grinding roller and bull ring is provided with perching knife; Said perching knife is connected with driving shaft, and said grinding roller also is connected and is positioned at the upper end of perching knife through connecting rod with said driving shaft, and said perching knife, grinding roller and bull ring are positioned at the grinding chamber of grinder; Be provided with the classification chamber in the upper end of said grinding chamber; In said classification chamber, be provided with classifying turbine, it is characterized in that, between said grinding chamber and classification chamber, be provided with the tapering transition face; Said perching knife is a convex arc edge in a side that is positioned at bull ring; Hypomere at said convex arc edge is provided with longitudinal baffle; Said convex arc edge is provided with second convex arc edge that seamlessly transits in the upper end that is positioned at longitudinal baffle, said perching knife is provided with top flap at the top on the said second arc limit.
Wherein, the surface of described tapering transition face is streamlined, or is the surface of taper seat shape.
Wherein, said longitudinal baffle is pressed close to the edge of perching knife convex arc edge, and vertical with the knife face of said perching knife.
Wherein, the upper end of said longitudinal baffle is an arcs of recesses.
Wherein, the angle of the said convex arc edge and the second convex arc edge intersection tangent line is 160 °～175 °.
Wherein, the knife face of said top flap and perching knife is vertical and press close to the edge at perching knife top.
Wherein, the angle of the top of said perching knife and intersection, the second convex arc edge end is 30 °～50 °.
Wherein, the top of said perching knife is the arcs of recesses limit.
Wherein, the opposite side of said perching knife is the arcs of recesses limit, and the bottom of said perching knife is horizontal straight flange.
The advantage and the beneficial effect of the utility model are: the utility model is through with being provided with the tapering transition face between grinding chamber and the classification chamber, thereby optimized the pipeline of airflow passes, avoided the air-flow of discharging to be stopped, reduced the excessive pulverizing of material.In addition through perching knife is designed to convex arc edge in a side that is positioned at bull ring; Hypomere at convex arc edge is provided with longitudinal baffle; Convex arc edge also is provided with second convex arc edge that seamlessly transits in the upper end that is positioned at longitudinal baffle, perching knife is provided with top flap at the top of second convex arc edge.Such structure more helps material that perching knife scoops up the dishing out of perching knife discharge end, and has increased the face of shedding of material, thus indirect increase effective abradant surface of grinding roller and bull ring, improve and pulverize quality and crush efficiency; Since the discharge end of perching knife panel have one be different from perching knife panel radian curved end, the further optimization of the direction that has realized material is dished out and the face of shedding of material is pulverized quality and crush efficiency thereby further improve.
