Abstract
A kind of efficiently from clear classifying screen, belonging to vibration screening machinery field, is the oscillation intensity in order to improve compass screen surface, ensures that sieve aperture is unimpeded, improves screening efficiency and designs.Primarily of screen frame, compass screen surface, vibrator, transmission gear for electric motor and vibration damping support device composition, two groups of eccentric block type vibrators are arranged on the side plate of screen frame, drive antiport by transmission gear for electric motor.Composition screen frame the crossbeam supporting compass screen surface is rectangle crossbeam, adopts rivet interlacement between the sieve plate bracing frame on rectangle crossbeam and rectangle crossbeam; The position that the side plate of screen frame is installed vibrator is provided with stiffening plate; Compass screen surface is made up of polylith cantilever lever sieve plate or Linear screen plate capable of being tensioned.The oscillation intensity of this classifying screen is large, and screen frame structural reliability is high, and sieve plate, while vibrating with screen frame, can produce secondary vibration, effectively remove the material be stuck in sieve aperture, ensures that sieve aperture is unimpeded, improves screening efficiency, be applicable to the classification to various material.
Description
Technical field
The utility model belongs to vibration screening machinery field, mainly relate to that compass screen surface oscillation intensity is large, screening efficiency is high, material not plug-hole and main frame long service life efficient from clear classifying screen.
Background technology
The classifying screen of existing structure, because of by limiting in screen box structure, vibrator structure and service life, its oscillation intensity is generally between 3 ~ 5g.For classifying screen, oscillation intensity is larger, its treating capacity and screening effect better, but excessive oscillation intensity can make shorten the service life of vibratory sieve, occurs earlier period damage.Desirable screening plant is that screen frame runs under low-inertia force, and compass screen surface vibrates under high oscillation intensity, makes material not plug-hole, and screening efficiency is high.Because the vibration frequency of compass screen surface is identical with screen box, prior art does not also have way simply and effectively to improve the oscillation intensity of compass screen surface, obtains higher screening efficiency.
Summary of the invention
The purpose of this utility model is to provide one efficiently from clear classifying screen, and this classifying screen can improve the oscillation intensity of compass screen surface effectively, ensures that sieve aperture is unimpeded, improves screening efficiency.
The utility model is realized by following measures, form primarily of screen frame, compass screen surface, vibrator, transmission gear for electric motor and vibration damping support device, two groups of eccentric block type vibrators are arranged on the side plate of screen frame, antiport is driven by transmission gear for electric motor, it is characterized in that: composition screen frame the crossbeam supporting compass screen surface is rectangle crossbeam, between the sieve plate bracing frame on rectangle crossbeam and rectangle crossbeam, adopt rivet interlacement; The position that the side plate of screen frame is installed vibrator is provided with stiffening plate; Compass screen surface is made up of polylith cantilever lever sieve plate or Linear screen plate capable of being tensioned.Screen angle α is 10 ~ 20 °, and vibrating direction angle β is 50 ~ 60 °.
The beneficial effects of the utility model are, the crossbeam supporting compass screen surface have employed rectangle crossbeam, and sieve plate bracing frame and rectangle crossbeam are riveted, and compass screen surface is made up of polylith cantilever lever sieve plate or Linear screen plate capable of being tensioned, make the oscillation intensity of this classifying screen large, screen frame structural reliability is high, and sieve plate, while vibrating with screen frame, can produce secondary vibration, effective removing is stuck in the material in sieve aperture, guarantee sieve aperture is unimpeded, improves screening efficiency, is applicable to the classification to various material.
Accompanying drawing explanation
Fig. 1 is efficient from sorting level sieve structure schematic diagram; Fig. 2 is the cross section view of the crossbeam supporting compass screen surface.In figure, the cantilever lever sieve plate of 1 be screen frame, 2 are vibrators, 3 are transmission gear for electric motor, 4 are compass screen surfaces, 5 are vibration damping support devices, 6 to be side plates, 7 be composition compass screen surface or Linear screen plate capable of being tensioned, 8 are crossbeams, 9 of supporting compass screen surface are sieve plate bracing frames, 10 are stiffening plates, 11 is rivet interlacement; α is screen angle, β is vibrating direction angle.
Detailed description of the invention
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described, forms primarily of screen frame, compass screen surface, vibrator, transmission gear for electric motor and vibration damping support device.Two groups of eccentric block type vibrators 2 are arranged on the side plate of screen frame 1, drive antiport by transmission gear for electric motor 3, make vibratory sieve produce the oscillation trajectory of straight line.Composition screen frame 1 crossbeam 8 supporting compass screen surface is rectangle crossbeams, adopts rivet interlacement between the sieve plate bracing frame 9 on rectangle crossbeam and rectangle crossbeam; The position that the side plate of screen frame 1 is installed vibrator is provided with stiffening plate 10; Compass screen surface 4 is made up of polylith Linear screen plate capable of being tensioned 7.Screen angle α is 15 °, and vibrating direction angle β is 55 °.
