Abstract
The utility model discloses a kind of flour mill with back powder device, comprise by central shaft, be arranged on the grinding roller frame on central shaft, be arranged on the shaft of grinding roller on grinding roller frame, be arranged on the grinding roller on shaft of grinding roller, and the main frame of the bull ring matching with grinding roller formation, the top of main frame is connected with analytical engine, it is characterized in that: comprise back powder device, described back powder device comprises tray, powder feeding bucket, described tray is arranged between analytical engine shell and host housing, with analytical engine shell, host housing is abutted against, the upper end of described powder feeding bucket communicates with the bottom of tray, lower end extend between bull ring and grinding roller.This abrasive dust function reduces the sky mill phenomenon of main frame, reduces vibration, improves mill efficiency, and the problem that can solve raymond mill and can not make a call to the above fine powder of 400 order.
Description
Technical field
The utility model relates to mechanical milling device, particularly a kind of flour mill with back powder device.
Background technology
Machinery milling device, common as raymond mill, in the time carrying out abrasive dust, first, material becomes to be less than the fragment of 20 millimeters through crusher in crushing, quantitatively sent in flour mill main frame and ground by electro-vibrating feeder.The Burnisher apparatus hanging in main frame on grinding roller frame rotates around central shaft, grinding roller is simultaneously around shaft of grinding roller rotation, under the effect of centrifugal force, outwards swing and compress bull ring, the perching knife that material is rotated is kicked up, thrown between grinding roller and bull ring, grind to reach because of rolling of grinding roller and bull ring and pulverize and abrasive action.
The analytical engine that powder after grinding is blown to main frame top by the air-flow of air blast carries out sub-sieve, and the excessively thick powder of fineness still falls in main frame and refaces, and the powder that fineness meets the specification flows to the wind into willy-willy collector, and after collection, getting rid of through flour extraction pipe is finished product.Air-flow after purification flows into air blast through the pipeline of willy-willy collector upper end.Wind path circulates.
This flour mill freely falls in main frame and refaces the excessively thick powder of fineness, its shortcoming is in free-falling process, to have very most of material under the impact of wind-force, cannot fall in the gap of bull ring and grinding roller and reface, so the empty mill of machine phenomenon is serious while causing grinding the above fine powder of 400 order, vibration is large, yields poorly.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and the sky mill phenomenon that provides a kind of flour mill with back powder device, this abrasive dust function to reduce main frame reduces vibration, improve mill efficiency, and the problem that can solve raymond mill and can not make a call to the above fine powder of 400 order.
The purpose of this utility model is to realize by following technical scheme:
With a flour mill for back powder device, comprise
By central shaft, be arranged on grinding roller frame on central shaft, be arranged on shaft of grinding roller on grinding roller frame, be arranged on the grinding roller on shaft of grinding roller and main frame that the bull ring that matches with grinding roller forms, the top of main frame is connected with analytical engine, unlike the prior art: comprise back powder device, described back powder device comprises
Tray, described tray is arranged between analytical engine shell and host housing, is abutted against with analytical engine shell, host housing,
Powder feeding bucket, the upper end of described powder feeding bucket communicates with the bottom of tray, and lower end extend between bull ring and grinding roller, and powder is sent between grinding roller and bull ring.
Also comprise powder feeding bucket bracing frame, one end of described powder feeding bucket bracing frame is connected with powder feeding bucket, and the other end is connected with grinding roller frame.
Dividing by analytical engine the thicker particle sifting out is the particle of miss the mark fineness, be collected into powder feeding bucket by tray, directly deliver between bull ring and grinding roller and reface by powder feeding bucket, avoid air blast on point impact that the Particle free sifting out returns, thereby reduce the sky mill phenomenon of main frame, reduce vibration, improved mill efficiency, and solved the problem that raymond mill can not be made a call to the above fine powder of 400 order.
