Description
Technical field
The invention belongs to the roller mill technical field for sleeping in that solid material grindings such as ore, slag, sinter are used, be specifically related to a kind of double material bed horizontal roller mill.
Background technology
Existing roller for sleeping in mill mainly is made up of the rotating cylinder and the free rotating pressure roller of an accumbency in cylindrical shell of a rest on four hydraulic pressure crawler shoes.Mainly contain running part, undercarriage arrangement, host machine part, slide shoe bearing, grinding roller system, take-up device hydraulic system, high-low pressure Lubricating-oil Station etc., rotating cylinder is driven by motor via reducer, drive pinion, bull gear.With certain speed rotation.Liner plate is laid in the cylindrical shell inboard, accumbency pressure roller in the cylindrical shell, and cylindrical shell charging and discharging end cap is passed at its two ends, is carried on the bearing block at two ends by pressure arm by oil cylinder.Cylindrical shell grinding band is with abrasion-proof backing block, and pressure roller is exerted pressure by the material of hydraulic cylinder on liner plate, and rotates with rotating cylinder.The roller mill that crouches is based on material bed crushed work mechanism, energy-efficient, have once by, repeatedly squeeze function, apparatus arrangement compactness, take up an area of less, advantages such as flow process is simple, easy operating.But because huge pressure is all born at the pressure roller two ends, and concentrate on the stage casing of pressure roller relatively for the support force of pressure roller at grinding district cylindrical shell, this bears very big moment of flexure with regard to the centre that makes pressure roller, produce very big stress, along with the rotation of pressure roller with cylindrical shell, under the effect of alternate stress, pressure roller is easy to produce rupture failure.
For this reason, the present invention is on the basis that does not change material bed pulverization principle, a kind of " recessed " type liner plate has been invented in design, under the situation that does not change running parameter, original material bed is divided into two to be become " extra quality bed ", each section material bed is in a corresponding crawler shoe respectively and supports the top, make cylindrical shell stressedly also improve, the stress deformation of pressure roller shaft reduces, the life-span prolongs.
In addition, the roller mill is a low-speed heave-load thump equipment owing to crouch, and its running stability is had higher requirement, existing roller mill still adopts patrilineal line of descent with only one son in each generation moving, flank profil width to the gear ring of this design will be very big, tooth force on the gear ring is also very big, for this reason, the present invention has designed a kind of pair of kind of drive, this kind of drive reduces by half the tooth force of every pair of engagement, flank profil width, the transmission that can reduce the transmission gear ring that is installed on cylindrical shell advantage such as tend to be steady, and can reduce the axial length of cylindrical shell.
Summary of the invention
The objective of the invention is to overcome the deficiency of the existing roller mill that crouches, make improvements, a kind of double material bed horizontal roller mill is provided,
To achieve these goals, the present invention mainly improves both ways,
1, on the basis that does not change material bed pulverization principle, the extruding grinding district of the roller mill that crouched is originally become extra quality bed by single material bed by " recessed " type liner plate, extruding grinding material bed is constant at axial total length, this " recessed " type liner plate constitutes (see figure 3) by main liner plate and secondary liner plate, pressure roller has also been made corresponding change, the wear-resisting pattern zone at original middle part has been divided into two parts, and the centre is that light face wearing layer separates (see figure 4).This programme also can independently be used to pass on a skill from a master to a single disciple the roller mill for sleeping in of flowing mode.
2, change two transmissions into original patrilineal line of descent with only one son in each generation is moving, two kinds of forms are specifically arranged, the one, the two transmission (see figure 5)s of single motor, the 2nd, the two transmission (see figure 6)s of bi-motor.So-called two transmission is exactly that two gear transmission power are arranged on the bull gear of cylindrical shell.This programme also can independently be used for the roller mill for sleeping in of thin material bed.
Two kinds of schemes are combined into one, and promptly form double material bed horizontal roller mill.
