Abstract
The utility model discloses a superfine vertical pulverizing machine which comprises a host machine body (16), a host machine shell (17), an electric motor (7), a speed reducer (6) connected with the electric motor (7), a grinding pan (5) driven to rotate by the speed reducer (6), and a grinding wheel (2) driven to rotate relatively by the grinding pan (5); and the superfine vertical pulverizing machine is characterized in that the grinding wheel (2) is provided with a sensing board for an upper electronic limit (3) and a sensing board for a lower electronic limit (4), the host machine body (6) and the host machine shell (17) are respectively provided with an approaching switch. When a hydraulic cylinder lifts up, the upper approaching switch approaches the sensing board for the upper electronic limit, and after reaching a preset distance, the approaching switch gives an electronic signal to stop the hydraulic cylinder, thus enabling a pull rod not to collide with the host machine body, and further preventing the equipment from being damaged; and similar condition appears to the lower electronic limit, thus being capable of preventing the grinding wheel from pressing the grinding pan directly, and further preventing the base of the host machine body from loosening, the welding seams on the equipment from cracking, the bolts from loosening, and the like.
Description
Technical field
The utility model belongs to milling apparatus, particularly a kind of ultra-fine vertical flour mill.
Background technology
Ultra-fine vertical flour mill is for grinding and the usefulness of screening micropowders.Traditional ultra-fine vertical flour mill comprises charging mechanism, motor, decelerator, drives the mill disc of rotation, drives through mill disc and grind roller in relative rotation and apply the hydraulic cylinder of pulling force for the mill roller by pull bar through decelerator.The mill roller grinds the material on the mill disc, grinds at last to be micropowders.Traditional structure has following shortcoming: the mill roller upwards, downward power realizes that by hydraulic cylinder the rotation of mill roller is rotated by mill disc and realized, the rotation of mill roller and the pulling force of hydraulic cylinder make that the mill roller can grinding material.When host-initiated, require No Load Start, at this moment hydraulic cylinder rises and drives mill roller and pull bar motion, if hydraulic cylinder rise stroke is too high, can make pull bar knock the main frame body like this, causes device damage; When equipment moves, when the bed of material is reduced to a certain degree or does not have material, because the pulling force of hydraulic cylinder makes mill roller being pressed on the mill disc tightly, can make the strong vibration of main frame body like this, thereby cause the consequences such as base flexible, the weld cracking on the equipment, bolt looseness of main frame body.
Summary of the invention
Thereby the utility model purpose provides a kind of ultra-fine vertical flour mill that protective device makes its stable operation that has.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of ultra-fine vertical flour mill, comprise main frame body, host shell, motor, the decelerator that is connected with motor, drive the mill disc of rotation, drive through mill disc and grind roller in relative rotation through decelerator, it is characterized in that: be separately installed with the sensory panel of electronic limit and the sensory panel of following electronic limit on the mill roller, be separately installed with near switch on the main frame body He on the host shell.
Also be provided with mechanical position limitation on the described main frame body, mechanical position limitation comprises gag lever post, spacing bearing, locking nut, and spacing bearing is welded on the main frame body, and gag lever post cooperates by trapezoidal thread with spacing bearing, and locks by locking nut.
Described spacing bearing is provided with jackscrew.
The beneficial effects of the utility model are:
When hydraulic cylinder rises, go up near the sensory panel of switch near last electronic limit, can send an electronic signal to predefined distance back near switch makes hydraulic cylinder stop to rise, so just can not make pull bar knock the main frame body, cause device damage, following electronic limit in like manner can prevent to grind roller and directly be pressed in consequences such as the base flexible that causes the main frame body on the mill disc, the weld cracking on the equipment, bolt looseness.Instantly during the electronic limit cisco unity malfunction, the spacing point on the mill roller can and mechanical position limitation contact, the pressure of mill roller is stopped, in order to avoid damage equipment; Make its aim of stable operation based on above cause to reach the utility model protection equipment.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model mill roller stopping means structural representation;
Fig. 2 is an A portion partial enlarged drawing among Fig. 1;
Fig. 3 is a B portion partial enlarged drawing among Fig. 1.
The specific embodiment
As Figure 1-3, the utility model comprises main frame body 16, host shell 17, motor 7, the decelerator 6 that is connected with motor 7, drives the mill disc 5 that rotates, drives through mill disc 5 and grind roller 2, charging mechanism 1 in relative rotation, give the hydraulic cylinder 8 that mill roller 2 applies pulling force, last electronic limit 3 and the following electronic limit 4 and the mechanical position limitation 10 of restriction mill roller 2 range of movement by pull bar 9 through decelerator 6.The sensory panel of wherein going up electronic limit 3 is installed on the mill roller 2, is installed on the host shell 17 near switch; The sensory panel of following electronic limit 4 also is mounted on the mill roller 2, then is installed on the main frame body 16 near switch.Mechanical position limitation 10 on the main frame body 16 comprises gag lever post 11, jackscrew 12, spacing bearing 13, locking nut 14, rotates handwheel 15, spacing bearing 13 is welded on the main frame body 16, gag lever post 11 and spacing bearing 13 cooperate by trapezoidal thread, and by locking nut 14 lockings.Each mill roller 2 has only a cover mechanical position limitation 10, mechanical position limitation 10 is spacing positions of adjusting mill roller 2 by trapezoidal thread, rotate handwheel 15 and make gag lever post 11 precessions or back-out, adjust behind the spacing position of gag lever post 11 with jackscrew 12 and locking nut 14 and gag lever post is fixed (prevent when the work vibration because of equipment make gag lever post 11 loosening), thereby reach the spacing of mill roller 2.
When host-initiated, require No Load Start, at this moment hydraulic cylinder 8 rises and drives mill roller 2 and pull bar 9 motions, if it is too high that hydraulic cylinder 8 rises stroke, going up will be near last sensory panel near switch, can send an electronic signal to predefined distance back near switch and make hydraulic cylinder 8 stop to rise, prevent that pull bar 9 from knocking the main frame body, causes device damage; When equipment moves, hydraulic cylinder 8 can give the mill roller 2 one downward pulling force by pull bar 9, make mill roller 2 pulverize material on the mill disc 5, when the bed of material is reduced to a certain degree or does not have material, descending will be near following sensory panel near switch, can send an electronic signal to predefined distance back near switch shuts down integral device, prevent because the pulling force of hydraulic cylinder 8 directly is pressed on the mill disc 5 mill roller 2, cause the consequences such as base flexible, the weld cracking on the equipment, bolt looseness of main frame body.Instantly during electronic limit 4 cisco unity malfunctions, the spacing point on the mill roller 2 can and mechanical position limitation 10 contact, 2 pressures of mill roller are stopped, in order to avoid damage equipment.
