Abstract
The utility model provides a cantilever rod resonance screen surface vibrating screen, belongs to the field of vibration screening machinery, and aims at solving the problem of deep screening of humid granule coals. The cantilever rod resonance screen surface vibrating screen mainly comprises screen boxes, screen surfaces, motors, vibrators and a support frame. An integral screen surface is composed of the screen surfaces of a plurality of independent vibrating screen boxes through head-to-tail connection. Each screen box is arranged on the support frame through damper springs. The motors are respectively connected with the vibrators arranged on the screen boxes. The screen surface in each screen box is composed of a plurality of cantilever rod screen plates which are arranged in parallel. Each cantilever rod screen plate is composed of a plurality of elastic straight bars which are arranged in parallel mode, one ends of the elastic straight bars are fixed, and the other end of the elastic straight bars are arranged in freely cantilevered mode. The inclination angle of the screen surfaces of the screen boxes is between 20-30 degrees. The vibration amplitude of the screen surfaces of the screen boxes is between 9-12 millimeters. The vibration frequency of the screen surfaces of the screen boxes is between 890-970 rounds per minute (r/min). The elastic straight bars of the cantilever rod screen bars are made of spring steels. Aperture ratio of the screen surfaces is high and vibration intensity of the screen surfaces is large, and therefore the cantilever rod resonance screen surface vibrating screen can effectively clear away materials clamped in screen seams, enables a screening machine to have high processing volume and high screening efficiency, and can be widely used for screening various humid fine-level materials.
Description
Technical field
The utility model belongs to the vibration screening machinery field, mainly relates to carry out moist fine particulate coal the cantilever lever resonance screens vibration screen of dry deep-sizing.
Background technology
Screening is an important step in the coal processing and utilization process, the particularly dry deep-sizing of moist fine particulate coal (3mm-13mm), is one of hot issue of world today's screening Science and Technology research.Because coal is in recovery process, owing to the reasons such as coal seam infiltration, the dustproof water spray in down-hole and other mismanagement cause the raw coal free moisture more than 7%, this moist fine particulate coal is because granularity is little, specific area is large, add the existence of the compositions such as free moisture and clay, bonding is agglomerating mutually, be attached to and stop up sieve aperture on the compass screen surface, make the screening effect variation, screening process worsens.Existing flip-flow screening machine, piano wire screen, cascading sieve, single-beam sieve and vibration sieve etc. have all been obtained gratifying achievement in theory and practice, but only are adapted to the screening operation of partition size more than 6mm.Just helpless less than the moist fine particulate coal of 6mm for partition size.So, the vibratory sieve of urgent need a kind of deep screening moist fine particulate coal of exploitation (partition size can reach 3mm).
Summary of the invention
The purpose of this utility model provides a kind of cantilever lever resonance screens vibration screen, and this vibratory sieve has solved moist fine particulate coal and carried out the stifled sieve aperture of material that exists in the dry deep-sizing, the difficult problem that treating capacity is little and screening percentage is low.
The utility model is realized by following measures, mainly formed by screen box, compass screen surface, motor, vibrator and bracing frame, it is characterized in that: the whole compass screen surface of vibratory sieve is that the compass screen surface by the screen box of a plurality of Independent Vibrations connects to form from beginning to end, each screen box is installed on the bracing frame by shock-absorbing spring, and motor is connected with vibrator on the screen box; Compass screen surface in each screen box is installed side by side by polylith cantilever lever sieve plate and is formed, and every cantilever lever sieve plate is to be fixed by many ends, and the Elastic Straight of other end free arm rearranges at the sieve plate framework.The screen angle of screen box is 20-30 °; Amplitude is 9-12mm; Vibration frequency is 890-970r/min; The Elastic Straight material of cantilever lever sieve plate is spring steel.
The beneficial effects of the utility model are, the mass of vibration of whole screen(ing) machine is light, the percent opening of compass screen surface is high, oscillation intensity is large, the Elastic Straight of cantilever lever sieve plate can produce secondary vibration under the once vibration of screen box, can effectively remove the material that is stuck in the sieve seam, make the treating capacity of screening machine large, screening efficiency is high.Can be widely used in sieving the material of various moist fine particulate levels.
