Description
(1) technical field:
The present invention relates to the powder process equipment, be specially a kind of centering type grinding roller list dual-gripper ring roller mill.
(2) background technology:
For the abrasive dust main frame that solves traditional single support ring roller mill shakes the problems such as large, that noise is high, grinding efficiency is low, output is little, mechanical loss is large, patent of invention that the applicant has proposed a kind of " straight-through type double-support ultra-fine ring roller grinder ", its abrasive dust main frame adopts dual-gripper and top charging, material after multilayer is ground outside the bottom is transported to machine the structure of grader.The abrasive dust main frame of this ring roller mill is not subjected to grader classification quantitative limitation, discharging does not leak outside, so under equal service condition, can throw in more material, can make material bed thicker between grinding roller and the bull ring, improved grinding efficiency, alleviated mechanical collision and wearing and tearing between grinding roller and the bull ring, so abrasive dust main frame noise is low, mechanical loss is little, output is higher.
Further research is found, along with the improvement of " straight-through type double-support ultra-fine ring roller grinder " structure, original grinding roller mechanism has been not suitable with the raising of production capacity.
The Burnisher apparatus of superfine ring-roll mill still adopts traditional structure, be that grinding roller is coaxially installed on the shaft of grinding roller, shaft of grinding roller is installed in the radial groove of offering on the grinding roller frame, and the rotation of grinding roller frame produces centrifugal force, grinding roller is mobile being pressed on the bull ring radially, and both interaction partners therebetween material roll.
Roll in the process, can't disposablely pulverize such as large granular materials, the reaction force of large granular materials bump grinding roller then makes grinding roller with radially opposite direction rollback in chute, continues down to mill unclassified stores thereby dodge out large granular materials.
And the vibrations when the continuous bump between grinding roller and the large granular materials has caused flour mill work just because the vibrations of flour mill have caused the rotating speed of abrasive dust main frame to be restricted and can't to improve, and then have limited efficient and the production capacity of flour mill.
(3) summary of the invention:
For the weak point that single dual-gripper superfine ring-roll mill Burnisher apparatus remains, the objective of the invention is to design a kind of centering type grinding roller list dual-gripper ring roller mill that alleviates vibrations and then enhance production capacities.
Can realize the centering type grinding roller list dual-gripper ring roller mill of above-mentioned purpose, the shell of its abrasive dust main frame is installed on the base, Burnisher apparatus and bull ring are located in the described shell, described Burnisher apparatus is installed on the main shaft, described bull ring and shell gapless are installed, the lower end of described main shaft is supported by main shaft lower bearing list and is installed, or install by main shaft upper bearing (metal) and the dual-gripper of main shaft lower bearing the top and bottom of main shaft, difference is that described Burnisher apparatus is centering type grinding roller mechanism, comprise the grinding roller frame, grinding roller and shaft of grinding roller, described shaft of grinding roller is divided into three sections, be respectively, the concentric shaft part of hypomere and the eccentric shaft part of interlude, described eccentric shaft part and the coaxial installation of the axis hole of grinding roller, the axle center of described concentric shaft part is in main shaft rotation center radially, and the axle center of described eccentric shaft part deviates from the axle center of concentric shaft part with the opposite direction of main shaft gyration; Centering type grinding roller mechanism comprises that also the shaft of grinding roller that promotes concentric shaft part pushes away frame and thrust mechanism, described shaft of grinding roller pushes away the frame slip and is located in the annular groove of grinding roller frame, described grinding roller is located at shaft of grinding roller and is pushed away in the frame, described concentric shaft part is snug fit at or is snug fit at by axle bed in the radial slot of annular groove top and bottom grinding roller frame, and the thrust mechanism that shaft of grinding roller is pushed away frame generation radial thrust is located at grinding roller frame annular groove rear portion.
Utilize thrust mechanism to apply an extra radial pressure to grinding roller, the centrifugal force stack of this radial pressure and grinding roller self produces larger grinding pressure and acts on the material, thereby obtains the production capacity of larger crushing efficiency and Geng Gao.
The mounting means in described concentric shaft part and axle bed hole is being slidingly installed of axle and axle bed hole, or is being slidingly installed of axle and axle bed hole internal axle sleeve, or is that axle cooperates installation with the rolling of axle bed hole inner bearing.
The mounting means of described eccentric shaft part and grinding roller axis hole is being slidingly installed of axle and axis hole, or is being slidingly installed of axle and the interior sliding shaft sleeve of axis hole, or is that axle cooperates installation with the rolling of axis hole inner bearing.
Described thrust mechanism can adopt hydraulic mechanism or adopt air pressure mechanism.
Described centering type grinding roller mechanism also can not dispose shaft of grinding roller and push away frame and thrust mechanism, and centering type grinding roller mechanism relies on centrifugal force work.
Described grinding roller can be made as one deck, be to improve abrasive dust efficient, and described grinding roller can be made as two-layer or multilayer, and is corresponding, offers on the described bull ring and one deck, two-layer or one, two or more pieces mill road that the multilayer grinding roller is corresponding.
Advantage of the present invention:
1, the abrasive dust main frame of centering type grinding roller list dual-gripper ring roller of the present invention mill adopts thrust mechanism that centering type grinding roller mechanism is applied extra-push model except centrifugal force, increase grinding roller to the grinding pressure of material, thereby can obtain the further raising of better crushing effect and production capacity.
2, the present invention just transforms Burnisher apparatus, and the agent structure of original ring roller mill abrasive dust main frame does not have any change, does not have the impact on the mechanical performance of abrasive dust main frame, but has obtained obvious prouctiveness.
3, the present invention adopts eccentric shaft of grinding roller structure, grinding roller in the course of work has one to rotate reciprocal beat amount with the flour mill main shaft with respect to the concentric shaft part of shaft of grinding roller, can make grinding roller easily, flexibly, effectively dodge the bump of large granular materials, vibrations when alleviating flour mill work, be beneficial to the raising of the flour mill speed of mainshaft, because square being directly proportional of the size of centrifugal force and rotating speed, therefore can increasing considerably production capacity and enhance productivity.
