A side plate of a sieve frame of the vibration sieve is fixed with a tubular vibrating beam through an annular radial rubber spring; the upper part of the tubular vibrating beam is provided with halftone support brackets supporting a screen mesh, and two ends of each group of halftone support brackets are provided with halftone supports; a rubber decreasing vibration strip is fixed on each halftone support. Tubes at two ends of the tubular vibrating beam are provided with high-frequency vibration electrical motors. The screen mesh of the vibration sieve is paved on the rubber decreasing vibration strip of the halftone support. The vibration electrical motors are connected with a transducer and a control computer, and each vibration electrical motor is controlled to operate synchronously by the control computer. The vibrating beam type high-frequency vibration sieve has high vibrating frequency, large producing ability as well as adjustable amplitude and frequency, can be widely used for accurate screen separation of fine screen hole grade and wet state materials such as iron ore crocus and petroleum drilling mud, etc.
Description
Technical field
The utility model belongs to the vibration screening machinery field, mainly relates to vibration frequency and screening efficiency height, the vibration beam type high frequency shale shaker that production capacity is big.
Background technology
The vibratory sieve of industrial and mining enterprises' production application mainly is to realize screening operation by the mode that vibrator driving screen box vibrates.Because the volume and weight of vibratory sieve screen box is all bigger, its vibration frequency directly influences the service life of vibratory sieve screen box.So improving the vibration frequency of vibratory sieve is restricted.The vibrator and the screen cloth of existing vibration sieve directly tap into capable screening operation, because the position that is connected is several points, cause the vibration of whole compass screen surface inhomogeneous, so also be difficult to improve the screening efficiency and the production capacity of vibratory sieve.
Summary of the invention
The purpose of this utility model provides a kind of vibration beam type high frequency shale shaker, and this vibratory sieve adopts walking beam to drive the screening principle that the holder web plate makes the screen cloth vibration, can improve the vibration frequency and the screening efficiency of vibratory sieve greatly.
The utility model is realized by following measure.Mainly be made up of bearing, screen frame, walking beam and screen cloth, it is characterized in that: screen frame is installed on the bearing, is made up of biside plate, discharge gate, backboard and feed box, and by crossbeam biside plate is connected together; Vibratory sieve has 2-6 tubular type walking beam, is provided with the holder web plate support of mesh support screen above the tubular type walking beam, 2 holders of every group of holder web plate support two ends welding web plate, and the rubber damping bar is fixed on the holder web plate; In order between the screen cloth that guarantees tensioning and the holder web plate certain pressure to be arranged, the upper surface of holder web plate is downward-sloping arc shooting, makes compass screen surface be the approximate circle arc; Screen cloth two ends line and horizontal line angle α are 20-30 °, with the profound high H of curved screen be the 80-130 millimeter.The two ends of walking beam are installed in by the annular radial rubber spring on the side plate of screen frame, in the pipe at two ends vibrating motor are installed; The screen cloth of vibratory sieve be laid on holder web plate rubber damping bar above, exhaust end is fixed on the discharge gate of screen frame, material feeding end is fixed on the backboard by spring take-up; The material feeding end of screen cloth and both sides are by sponge rubber and screen frame sealing.In order to keep the smooth of screen cloth, the rubber damping bar on the holder web plate should be parallel to each other, and parallel with the tubular type walking beam.Vibrating motor is the built-in type dither motor of a side band eccentric block, be connected with the control computer with frequency converter, by the revolution of each vibrating motor of computer control, guarantee each vibrating motor synchronous operation of tubular type walking beam, holder is synchronously held screen cloth and is carried out dither.Described screen cloth is to be bonded by two kinds of order grade stainless steel screen clothes and Polyurethane.
Vibrating motor one side has two eccentric blocks, and the combination angle of eccentric block can be adjusted, in order to change the amplitude of walking beam.
In vibratory sieve when work,, moisture order stage material falls into the feed box of screen frame from outside chute, slips into the material feeding end of screen cloth.Screen cloth holds and carries out under the effect of circular motion in the holder of walking beam, and the springing material moves downward screening along the curved surface track.Material and moisture less than mesh are fallen chute off the net through screen cloth, are discharged by discharge gate greater than the material of mesh, finish the accurate classification of order level water-containing materials.
The beneficial effects of the utility model are, vibratory sieve adopts the vibration corbel to hold screen cloth, elastic tension before and after the screen cloth, and with the walking beam dither, screen frame does not participate in vibration.Have the vibration frequency height of screen cloth, production capacity is big, the characteristics of amplitude and frequency adjustable.Can be widely used in the accurate screening of detailed catalogue level hygrometric state materials such as iron ore grinding machine abrasive dust, oil drilling slurry.
Description of drawings
Fig. 1 and Fig. 2 are structural representation of the present utility model, among the figure 1 for discharge gate, 2 for side plate, 3 for connect crossbeam, 4 for feed box, 5 for backboard, 6 for spring take-up, 7 for the tubular type walking beam, 8 for holder web plate support, 9 for the holder web plate, 10 for the rubber damping bar, 11 for the annular radial rubber spring, 12 for screen cloth, 13 for vibrating motor, 14 for bearing, α be that screen cloth two ends line and horizontal line angle, H are the profound height of screen cloth two ends line and curved screen.
