Abstract
The utility model relates to a high-frequency translational sieve which belongs to the field of vibration screening machinery. The high-frequency translational sieve is designed to solve the problems that when the existing electromagnetic high-frequency vibration mesh sieve is used for fine or super-fine screening of materials, only an electromagnetic microvibration is used to drive a link rod and a swinging rocker to knock and vibrate a sieve, so the whole screening surface can not obtain uniform vibrating force, and has small vibration amplitude, easy blocking at part of the sieve, lower screening efficiency, small processing quantity and the like. The high-frequency translational sieve is characterized in that an inertial vibrator or a vibrating motor is adopted as a vibrating source at both symmetrical sides of the sieve, the sieve is thoroughly translational, the frequency reaches 48.33 Hz, and double-amplitude reaches 4 mm, so problems of ununiform vibrating force and small vibration amplitude of the screening surface of an electromagnetic high-frequency vibration mesh sieve are solved, the screening efficiency is improved, and the processing quantity is large. The high-frequency translational sieve can be widely applied to fine or super-fine material screening such as metallurgy, milling grinding, chemical engineering paint, abrasive material processing and the like.
Description
Technical field:
The utility model belongs to the vibration screening machinery field, mainly relates to thin or ultra-fine material screening operations such as metallurgical ore grinding, chemistry painting industry, abrasive material processing, can effectively improve the screening efficiency of vibratory sieve and the high frequency translation dusting cover in service life.
Background technology:
The electromagnetic high-frequency vibration sieve of utilization is when carrying out thin or ultra-fine material screening at present, only rely on that electromagnetism is little to shake drivening rod and swing rocking arm to knock screen cloth vibration, owing to knock and be limited in scope, and the exciting force that whole compass screen surface is obtained is inhomogeneous, amplitude is little, and the easy plug-hole in local screen cloth place causes screening efficiency low, treating capacity is little, and the screen cloth that is beaten the place is fragile.
The utility model content:
The utility model provides a kind of high frequency translation dusting cover, and it is even to make compass screen surface obtain exciting force everywhere during work, and amplitude is relatively big, material is difficult for plug-hole, the screening efficiency height, and treating capacity is big, exciting force is little to the destructive power of screen frame during the screen(ing) machine operation, whole screen(ing) machine long service life.
The utility model is realized by following measure.The body vibration sieve is made up of screen frame, compass screen surface, exciting source, vibration damping holder device.Its arrangement is: (exciting source can be an inertia vibrator in the screen frame bilateral symmetry two identical exciting sources of performance to be installed, also can be vibrating motor), the axis of two exciting sources is parallel to each other and perpendicular to horizontal plane, the application point that two exciting sources generation is simultaneously made a concerted effort will act on screen(ing) machine joins on the center of gravity of shaking, make the exciting source direction of rotation unanimity of both sides during work, its operation characteristic is: two exciting sources produce exciting force make a concerted effort drive compass screen surface and do " plane translation " circular motion track, make the motion of material existing X-direction and Z-direction on compass screen surface, have again to climb rolling of Y direction and move along screen angle.Can be during design according to characteristics that are sized material and requirement, screen angle is selected between 25 °～40 °; The number of plies of compass screen surface can be by the technological requirement that is sized operation by the selection of one deck to multilayer.
The utility model has compensated the deficiency of electromagnetic high-frequency vibration sieve, and changed the stressed and motion mode of conventional mechanical inertial oscillation high frequency sieve, make vibratory sieve have that screening efficiency height, treating capacity are big, the characteristics of long service life, help the high efficiency and the large scale development of high frequency sieve.
Description of drawings:
Accompanying drawing 1 and Fig. 2 are structural representation of the present utility model, i.e. high frequency translation dusting cover is assemblied by screen frame 1, compass screen surface 2, exciting source 3, vibration damping holder device 4.Its arrangement is: (exciting source can be an inertia vibrator in screen frame 1 bilateral symmetry two identical exciting sources 3 of performance to be installed, also can be vibrating motor), the axis of two exciting sources 3 is parallel to each other and perpendicular to horizontal plane, the application point that two exciting sources, 3 generations are simultaneously made a concerted effort will act on screen(ing) machine joins on the center of gravity of shaking.Screen frame 1 is installed on the vibration damping holder device 4, makes the exciting source 3 direction of rotation unanimities of both sides during work.Can be during design according to characteristics that are sized material and technological requirement, the inclination alpha of compass screen surface 2 is selected between 25 °～40 °; The number of plies of compass screen surface 2 can be by the selection of one deck to multilayer.Fig. 2 be the A of Fig. 1 to view, expression be the relative position relation of both sides exciting source 3.
The specific embodiment:
In conjunction with the accompanying drawings 1 and Fig. 2 one of them embodiment of the present utility model is described: a kind of high frequency translation dusting cover GPX2020 is assemblied by screen frame 1, compass screen surface 2, inertia vibrator 3, vibration damping holder device 4.Its arrangement is: the axis of identical inertia vibrator 3, two inertia vibrators 3 of two performances being installed in screen frame 1 bilateral symmetry is parallel to each other and perpendicular to horizontal plane, and two inertia vibrators 3 produce the application point of making a concerted effort and will act on the screen(ing) machine ginseng and shake on the center of gravity simultaneously.Screen frame 1 is installed on the vibration damping holder device 4, makes the inertia vibrator 3 direction of rotation unanimities of both sides during work.GPX2020 type high frequency translation dusting cover, what compass screen surface 2 produced during work is " plane translation " circular motion track, and double-amplitude is 4mm, and frequency is 48.33HZ, and the compass screen surface width is 2000mm, and screen length is 2000mm, and the compass screen surface design is one deck, and screen angle α is 30 °.
