Technical field
The utility model relates to a kind of screening plant, be specifically related to a kind of single-deck screen subset, be applicable to the screening of the large-scale treating capacities of fine fraction difficult screened material such as mineral, coal, according to the granular size difference, the screening plant that the treating capacity difference is effectively sieved belongs to machinery manufacturing technology field.
Background technology
In recent years, different progress has been arranged in the development of screening plant both at home and abroad, very big progress has been arranged in the processing of moist fine particulate level difficult screened material especially, along with modern development in science and technology, everybody has also had very big breakthrough in the dry method screening, particularly under the situation to the western lack of water of China, the dry method screening is particularly important, more require the characteristics of efforts at environmental protection, as screening plants such as common circular shale shaker, rotary probability screen, vertical cylinder sieve, banana screens, there is the problem that much is difficult to resolve on its mechanical strength and the screening effect.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of single-deck screen subset is provided, and this equipment is made up of multistage sieve basket, each sieve basket self-movement separately; Screening adopts amplitude adjustable separately, satisfy the screening of difficult sieve fine fraction and moist material, the employing double-amplitude is 14-30mm, oscillation intensity is 5-8Aw/g, high inclination-angle 15-30 °, change the frame for movement and the compass screen surface structure of sieve, adopt body vibration, the big vibration of sieve basket, in screening process, compass screen surface is rectilinear motion up and down, obtains good screening treating capacity, by the driven by motor vibrator, make the sieve basket do mechanical movement, carry out vibration damping one time by primary and secondary shock-absorbing spring group, complete machine carries out the secondary vibration damping by the secondary shock-absorbing spring, reduces the dynamic load of sieve to ground; Sieve is formed dust cover by protective plate, prevents from that the material dust from waving to raise, and reduces the pollution to air, keeps good working environment, thereby reaches environmental requirement.
The utility model is realized with following technical scheme: a kind of single-deck screen subset, this equipment includes frame, frame one side has independent adjustable motor supporting leg, the sieve basket is arranged on the frame, it is characterized in that: multistage sieve basket is arranged on the described frame, and the sieve basket is made up of compass screen surface and vibrator, sieve basket and compass screen surface are participated in vibration simultaneously, there is safety guard every section sieve basket both sides, between frame and the vibrator main vibration spring are arranged, organic frame secondary shock-absorbing spring between frame and the ground.
Described compass screen surface is made up of the independently square sifter of polylith, and compass screen surface spreads by pressing plate, wood and wood spreads backing plate and is fixed on the sieve basket.
Vertically be arranged with some silk screens on the described square sifter, silk screen is fixed on the silk screen plate, and is porose on the silk screen plate, its bore dia is slightly larger than the silk screen diameter, the silk screen two ends are all gapped apart from frame, and silk screen is rotatable and play on the silk screen plate, and silk screen direction and flow direction of material are vertical configuration.
Described vibrator is connected with motor on the independent adjustable motor supporting leg by being flexible coupling.
Multistage sieve basket is arranged on the described frame, and all there is safety guard every section sieve basket both sides, and the safety guard between the multistage sieve basket has constituted dust cover.
The utility model has the advantages that: this equipment is by complete machine oscillation, and the secondary vibration damping makes complete machine in the course of the work, and the vibration force of carrying the basis is reduced; Primary and secondary vibration (main shaking) drives the sieve basket by vibrator, carries out the strong vibration of need of work; Secondary vibration damping (inferior shaking) is to reduce screening plant at work, to the vibration force of basic body, also reduces the sound that mechanical impact takes place simultaneously, thereby reduces noise, satisfies environmental requirement; The compass screen surface of sieve basket is combined by a plurality of square sifters, as required can be by the combination of multistage sieve basket; Silk screen vertically is arranged in the square sifter, and rotatable and play produces rotation under the vibration effect, clear up compass screen surface automatically; Motor independence adjustable support leg is fixed on a plurality of monomer adjustable supports by a plurality of motors, can be according to the needs free adjustment motor height of screening plant, the center that guarantees motor and vibrator keeps synchronous concentric motion at sustained height, prolongs the service life of each parts.
