Abstract
The utility model discloses a high-efficiency high-frequency vibratory screen belonging to the field of vibrating screening machines, which solves the problems of the unstable direction angle of high-frequency screening and unclean dewatering of coals.A box-type gear compelling vibration exciter adopted by the vibratory screen is arranged above a screen frame and is driven by a dynamo-electric gear with a vibration direction angle of 30 - 40 degrees. The feeding end of the screen frame is equipped with a section of a screen surface. The inclination angle of the screen surface with the horizontal plane is 45 degrees. The rest section of the screen surface is a zigzag screen surface comprising a plurality of sections of zigzag folded surface, wherein the negative inclination angle of each section of the zigzag folded surface with the horizontal plane is 3 - 10 degrees. The vibration direction angle of the screen box is accurate and stable, so that the running speed of materials is stable and the material layer is uniform.Sheet shape slime can be cut off repeatedly by the zigzag screen surface, so that slime blocks are turned off and loosened and the dehydration effect of the dehydration effect is improved. The high-frequency vibratory screen is suitable for the dehydration of viscous and damp materials.
Description
Technical field
The utility model belongs to the vibration screening machinery field, mainly relates to improve the high efficiency high frequency vibratory sieve of the dehydrating effect of adhesional wetting materiels such as coal slime.
Background technology
High frequency shale shaker of the prior art mainly is coal slime dewatering, and vibrator is by two electric motor driven motor synchronizing linear vibration exciters.Compass screen surface is whole planar shaped, and screen angle is negative 5 °, and promptly the discharge end compass screen surface is higher than the compass screen surface of material feeding end.Because the concentration of coal slime and the flow of feed constantly change, and make the thickness of feed layer on the compass screen surface inhomogeneous, have caused the instability of the synchronous effect and the vibrating direction angle of vibratory sieve.In addition, coal slime is in screening process, and the sheet coal slime that forms on the negative incidence compass screen surface of integral body is not loose, and the moisture in the coal slime takes off unclean, and the dehydrating effect of vibratory sieve is affected.
Summary of the invention
The purpose of this utility model provides a kind of high efficiency high frequency vibratory sieve, and this vibratory sieve can cut off the sheet coal slime that forms on the compass screen surface repeatedly, improves the dehydrating effect of vibratory sieve, improves the efficient of screening.
The utility model is realized by following measure.Mainly form by screen frame, vibrator, compass screen surface and vibration damping support device, it is characterized in that: described vibrator is that box gear forces vibrator, be installed in the top of screen frame, drive by a transmission gear for electric motor, make screen frame and compass screen surface form the straight-line oscillation track in fore-and-aft plane, vibrating direction angle is 30～40 °; At the material feeding end of screen frame one section compass screen surface with horizontal plane inclination angle at 45 is arranged, the zigzag compass screen surface that remaining compass screen surface is made up of the zigzag folding face of multistage, every section zigzag compass screen surface becomes 3～10 ° negative incidence with horizontal plane.In order to adapt to the needs of different material screening, it is 1～2 that box gear forces the quantity of vibrator, is connected with transmission gear for electric motor by universal drive shaft.
At the screen frame material feeding end and compass screen surface horizontal plane inclination angle at 45, can dewater and classification to material, can prevent that again adhesional wetting materiel is excessive, material is evenly distributed on the compass screen surface gradually.Zigzag folding face compass screen surface can cut off the sheet coal slime on the compass screen surface repeatedly, plays effect loose and that stir, is convenient to purify the moisture content in the coal slime.
The beneficial effects of the utility model are, use box gear and force vibrator, make the vibrating direction angle of screen box accurately stable, and the speed of service of material is stable, and the bed of material is even.Zigzag folding face compass screen surface can cut off the sheet coal slime that forms on the compass screen surface repeatedly, make the coal slime piece turn over, loose, improved the dehydrating effect of vibratory sieve, improved the screening efficiency of vibratory sieve.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model, Fig. 2 is the left view of Fig. 1, and 1 is screen frame, the 2nd among the figure, and box gear forces vibrator, the 3rd, and zigzag compass screen surface, the 4th, vibration damping support device, the 5th, material feeding end compass screen surface, the 6th, transmission gear for electric motor, α are that vibrating direction angle, the β of vibrator is that material feeding end screen angle, δ are the inclination angles of every section zigzag compass screen surface and horizontal plane.
The specific embodiment
Below in conjunction with a description of drawings embodiment of the present utility model.Mainly be made up of screen frame 1, vibrator, compass screen surface and vibration damping support device 4 etc., two box gears force vibrator 2, are installed on the driving beam of screen frame 1 top, are driven by transmission gear for electric motor 6 by universal drive shaft, and vibrating direction angle α is 35 °; There is one section to be 45 ° compass screen surface at the material feeding end of screen box with the horizontal plane angle of inclination beta, the zigzag compass screen surface 3 that remaining compass screen surface is made up of the zigzag folding face of multistage, every section zigzag compass screen surface 3 is negative 5 ° with the inclination angle δ of horizontal plane.
Claims (2)
