Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and is directed to rectangular particle sizing and has energy-conservation, consumption reduction, the efficient and housing construction large-scale horizontal reciprocating resonance screening machine without disorder vibration.
The purpose of this utility model is achieved in that
A kind of large-scale horizontal reciprocating resonance screening machine, it comprises the support of arranging from bottom to top, motor cabinet and screen box, between described support and motor cabinet, be provided with beam, between described motor cabinet and screen box, be provided with steel spring and flat spring assembly, steel spring is provided with two groups that left and right is arranged, two groups of steel springs are arranged between the two ends, left and right of motor cabinet and screen box, flat spring assembly is provided with many groups from left to right, every group of flat spring assembly comprises upper fixed seat, lower fixed seat and flexure strip, fixed seat is arranged on screen box, described lower fixed seat is arranged on motor cabinet, described flexure strip is arranged between upper fixed seat and lower fixed seat, the front and back bilateral symmetry of described motor cabinet is provided with vibrating motor, described vibrating motor, flat spring assembly and steel spring be oblique layout all, described vibrating motor is consistent with the oblique direction of flat spring assembly, the oblique opposite direction of described flat spring assembly and steel spring.
Preferred as one, in described screen box, be provided with from top to bottom the first horizontally disposed coarse fodder screen cloth, the second coarse fodder screen cloth and fines screen cloth, the flow field end of described the first coarse fodder screen cloth and the second coarse fodder screen cloth is provided with the coarse fodder mouth that gathers materials, the flow field end of described fines screen cloth is provided with the fines mouth that gathers materials, and the flow field end of described fines screen cloth below is provided with the powder mouth that gathers materials.
Preferred as one, the mesh size of described the first coarse fodder screen cloth and the second coarse fodder screen cloth is 4mm ~ 6mm, and the mesh size of described fines screen cloth is 2mm ~ 2.5mm.
Compared with prior art, the beneficial effects of the utility model are:
The utility model overcomes low, the rectangular particle of traditional vibration screening efficiency and screens out undesirable shortcoming, work with resonance form, utilizing symmetric double vibrating motor to produce exciting force drive motor seat vibrates in certain angle direction, drive the vibration of screen box generation resonance form thereupon, all the time there is in the horizontal direction reciprocally swinging in compass screen surface, make the forms of motion of rectangular particle for moving horizontally instead of bob, remove rate for the long material screen of 10mm and be greater than 98%, be more than the twice that screening effeciency is common screening machine.And because resonance principle has efficient energy-saving, Oscillation Amplitude is steadily adjustable, sound level is below 60dB, far below in industry mean level, can the similar vibration material screening machine of loss-rate low by 30 ~ 50%.Therefore this large-scale horizontal reciprocating resonance screening eedle has advantages of that for rectangular particle sizing energy-conservation, noise reduction, efficient and housing construction vibrate without disorder.
