Vertical roller grinder powder concentrator stator blade distance automatic regulating device
Technical field
The present invention relates to a kind of vertical roller grinder powder concentrator, particularly a kind of vertical roller grinder powder concentrator stator blade distance automatic regulating device.
Background technology
Vertical Mill integrates fragmentation, drying, grinding, classification to be carried, and production efficiency is high, and block, graininess and powder raw material can be worn into desired granular material.
Vertical mill system comprises main drive, millstone device, lubricating arrangement, hydraulic means, powder selection device etc.Powder concentrator will carry out classification through the powder concentrator stator blade by the comminuting matter that gas is brought up, and the fine powder that will meet the product fineness requirement filters out.In order to satisfy Vertical Mill to the adaptability of various materials, and the different finished product of control fineness, the spacing of roller mill separator stator blade is very important, when the finished product grain graininess requires when thinner, should reduce the spacing of stator blade, when the requirement of finished product grain graininess is thicker, should increase the spacing of stator blade.The spacing of some grinding machine stator blade of current stage can't realize adjusting for what fix, greatly reduces like this Vertical Mill to the adaptive capacity of grinding material.Some powder concentrator stator blade can be adjusted, but needs just can be finished after vertical mill system is shut down by the operator, i.e. stator blade spacing adjustment also is in the manual stage at present.Manually adjust the stator blade spacing and had a strong impact on the automaticity of Vertical Mill, and greatly reduce the operation rate of Vertical Mill.
Summary of the invention
The present invention provides a kind of vertical roller grinder powder concentrator stator blade distance automatic regulating device for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of vertical roller grinder powder concentrator stator blade distance automatic regulating device, comprise the annular driving-disc that is horizontally set on the powder concentrator center, described annular driving-disc is provided with the outside break slot that equates and be evenly arranged with powder concentrator stator blade quantity, be inserted with a bearing pin in each described outside break slot, described bearing pin vertically is fixed on the horizontal rocking arm, described horizontal rocking arm is with vertically pivot is affixed, described vertical pivot and powder concentrator stator blade are affixed, and described vertical pivot and powder concentrator are rotationally connected; The inner ring of described annular driving-disc and at least three uniform guide wheel frictional connections, described guide wheel is installed on the powder concentrator; The outer ring of described annular driving-disc and two driving gear engagements that are arranged symmetrically with, each driving gear is provided with a driving mechanism, and described driving mechanism is installed on the powder concentrator; Described bearing pin is multidiameter, and described annular driving-disc is bearing on the shaft shoulder of described bearing pin.
The advantage that the present invention has with good effect is: the difference that can require according to the different and finished product of material grindability, automatically adjust the stator blade spacing, select powder fineness thereby change, strengthen Vertical Mill to the adaptability of material, with the quick reply market demand, improve operation rate, be convenient to realize the automation of vertical mill system.Reasonable in design of the present invention, simple, dismounting and easy to adjust and manufacturing and maintenance cost are cheap, are conducive to ensure that production line turns round continually and steadily, have huge economic benefit.

The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1~Fig. 4, a kind of vertical roller grinder powder concentrator stator blade distance automatic regulating device, comprise the annular driving-disc 3 that is horizontally set on the powder concentrator center, described annular driving-disc 3 is provided with the outside break slot 10 that equates and be evenly arranged with powder concentrator stator blade 8 quantity, be inserted with a bearing pin 6 in each described outside break slot 10, described bearing pin 6 vertically is fixed on the horizontal rocking arm 7, described horizontal rocking arm 7 is with vertically pivot 9 is affixed, described vertical pivot 9 is affixed with powder concentrator stator blade 8, and described vertical pivot and powder concentrator 1 are rotationally connected; The inner ring of described annular driving-disc 3 and at least three uniform guide wheel 2 frictional connections, described guide wheel 2 is installed on the powder concentrator 1; The outer ring of described annular driving-disc 3 and two driving gears, 5 engagements that are arranged symmetrically with, each driving gear 5 is provided with a driving mechanism 4, and described driving mechanism 4 is installed on the powder concentrator 1; Described bearing pin 6 is multidiameter, and described annular driving-disc 3 is bearing on the shaft shoulder of described bearing pin 6.
Operation principle of the present invention:
When needs are adjusted the stator blade spacing, driving mechanism 4 is passed to annular driving-disc 3 with power, annular driving-disc 3 will drive horizontal rocking arm 7 and rotate, horizontal rocking arm 7 drives 8 rotations of powder concentrator stator blade, spacing randomly changing between the powder concentrator stator blade 8, thereby realized that automatic control adjusts the purpose of stator blade spacing, and rotating flexibly in order to guarantee driving-disc, transmission device is arranged symmetrically with two covers.
The present invention realizes 8 rotations of powder concentrator stator blade, thereby reaches the purpose that changes powder concentrator stator blade 8 spacings by set up horizontal rocking arm 7 in the end of powder concentrator stator blade 8.Annular driving-disc 3 plays crucial gearing in the present invention, annular driving-disc 3 is installed on the powder concentrator 1, under the effect of transmission device, annular driving-disc 3 can be around the central rotation of powder concentrator 1, driving force will be delivered on the bearing pin 6, bearing pin 6 drives horizontal rocking arm 7 rotations, and horizontal rocking arm 7 drives powder concentrator stator blade 8 and realizes together automatically adjusting the stator blade spacing.
Although the above is described the preferred embodiments of the present invention by reference to the accompanying drawings; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away from the scope situation that aim of the present invention and claim protect, can also make a lot of forms, these all belong within protection scope of the present invention.
