The invention discloses a suspension roller pulverizing machine with a vibration isolation structure. The suspension roller pulverizing machine comprises a drive unit, a suspension roller pulverizing unit and an analyzer unit which are arranged from bottom to top. The suspension roller pulverizing unit comprises a machine seat with a pulverizing ring lined inside, a pulverizing barrel fixed to the machine seat, a suspension roller assembly arranged in the pulverizing barrel and driven by the drive unit and an air inflow volute arranged around the side wall of the machine seat, wherein an inner cavity of the air inflow volute is communicated with an inner cavity of the pulverizing barrel through a flow guide port formed in the side wall of the machine seat, and the section of the air inflow volute is of a side opening structure shaped like a left square bracket formed by a top wall, a bottom wall and a vertical wall. The suspension roller pulverizing machine has the advantages that vibration of a main machine and vibration generated by the analyzer unit are isolated, and the phenomenon that a pulverizing barrel is vibrated to crack by the main machine is avoided.
Description
Technical field
The present invention relates to suspension mill, especially relate to the suspension mill with vibration insulation structure.
Background technology
Suspension mill is widely used in the industries such as metallurgy, building materials, chemical industry, mine, expressway construction, water conservancy and hydropower, carries out powder crushing process processing to mineral products material.Suspension mill is primarily of compositions such as support, spiral case, cylindrical shell, overhang roll assembly, analytical engine and transmission mechanisms; Extrude by the overhang roll assembly of the bull ring on support and rotation and grind powder process work.Along with equipment maximizes increasingly, suspension mill vibration problem is become increasingly conspicuous.Trace it to its cause, analytical engine rotor is rotatable parts, the overhang roll assembly be installed on main frame is also rotatable parts, and both vibrations can cause the phenomenons such as weldment sealing-off, abrasive dust cylindrical shell ftracture, support foundation bolt loosens, and whether it directly affects whole pulverized coal preparation system and can safely and steadily run.At present, in suspension mill equipment, the structure of isolating above-mentioned two vibration sources has two kinds: one increases spring between abrasive dust cylindrical shell and analytical engine, effectively the isolating technique of analytical engine vibration and main frame can be come, but the vibration because of main frame cannot be avoided to be shaken by abrasive dust cylindrical shell split, have a strong impact on it and produce.Another kind is supported abrasive dust cylindrical shell and analytical engine steelframe, separate with main frame, connect with main frame by adopting canvas and anchor ear, two vibration sources can be kept apart like this, reduce complete machine oscillation, avoid abrasive dust cylindrical shell to be shaken to split, but because of suspension mill processing is building stones, there is a large amount of stone grains to exist at the canvas place of abrasive dust cylindrical shell, these stone grains carry out moving and rubbing with canvas under the drive of high velocity air, canvas worn-off is caused and seriously leaks powder, directly affect the normal operation of suspension mill equipment.
Summary of the invention
The object of the invention is to provide a kind of suspension mill with vibration insulation structure.
For achieving the above object, the present invention takes following technical proposals:
The suspension mill with vibration insulation structure of the present invention, comprises the driver element, overhang roll abrasive dust unit, the analytical engine unit that arrange from bottom to top; The support of bull ring is lined with in described overhang roll abrasive dust unit comprises, be fixed on the abrasive dust cylindrical shell on described support, with be arranged in described abrasive dust cylindrical shell by the overhang roll assembly of described drive unit drives, and around the air intake spiral case that support sidewall is arranged, described air intake spiral case inner chamber is connected with abrasive dust cylinder lumen by the flow-guiding mouth be opened on support sidewall; " the side opening structure of ［ " font that the section configuration of described air intake spiral case is made up of roof, diapire and wall; It is described that " side opening of ［ " font is fastened on the sidewall of support, that is: described " ceiling edge of ［ " font is positioned at the upper surface of support, and " bottom wall edge of ［ " font is positioned in the land of support lower sidewall; Be positioned at and " between the ceiling edge of ［ " font and frame upper surface, be provided with the upper damping washer that abrasive rubber is made; Be positioned at that " be provided with the lower damping washer that abrasive rubber is made between the bottom wall edge of ［ " font and the described land of support lower sidewall, " diapire of ［ " font is by the land bolt of studs through described lower damping washer and support lower sidewall; " roof of ［ " font is fixedly connected with the lower nozzle of abrasive dust cylindrical shell by bolt.
The upper surface of described upper damping washer is single convex cone structure; The upper surface of described lower damping washer is biconvex cone structure, lower damping washer offers the through hole passed for described studs between the described biconvex conical surface, studs by rubber damping cover through described " diapire of ［ " font and the land bolt of described support lower sidewall.
Advantage of the present invention is mainly reflected in following several respects:
1, the section configuration of air intake spiral case is arranged to " ［ " font side opening structure be made up of roof, diapire and wall, and respectively the roof of air intake spiral case, diapire are connected with support by upper and lower damping washer, thus the isolating technique vibration (vibration produced during host driven overhang roll component operation) of main frame and analytical engine unit produced comes, avoid abrasive dust cylindrical shell and occurred by the main frame phenomenon split of shaking;
2, the section configuration of air intake spiral case is that " ［ " font side opening structure, plays the damping effect of flexural spring during work, that is: " ［ " font side opening place exists longitudinal extension amount, can eliminate the vibration from longitudinal direction;
3, the upper damping washer arranged between the roof and frame upper surface of air intake spiral case, and the upper surface of upper damping washer is arranged to single convex cone structure, play the effect of aiding support, stably support abrasive dust cylindrical shell and analytical engine parts, guarantee equipment normally runs;
4, the upper surface of upper damping washer is arranged to single convex cone structure, and the upper surface of lower damping washer is arranged to biconvex cone structure; Make the conical top of upper and lower damping washer contact with smooth spiral case roof, bottom wall surface like this, by reducing contact area, increasing contact, improve dust-proof effect.
