Hydrocyclone is to utilize the difference of centrifugal sedimentation speed that material is carried out classification, it also is the visual plant that constitutes closed circuit grinding with grinding machine, but the efficient of this equipment generally is not higher than 50%, need sand pump when closed circuit with grinding machine, the required pressure of hydraulic classiciation is also high, so the use of equipment has also caused crossing the complicated of the generation of pulverizing and system configuration.

Medium supination screening machine is a kind ofly can constitute closed circuit screening plant automatically with grinding machine, but the sieve pore blockade of this equipment is serious unusually, and continuous production can't normally be carried out, and causes the not success of this equipment.

A kind of vibrating helical spire screening machine is disclosed in the patent No. is 93206610 patent, this machine is the good equipment that an energy and grinding machine constitute automatic closed circuit grinding, efficient is up to more than 90%, strict with the physical dimension classification, sand return promotes automatically, and the existence of functions such as cleaning of falling automatically makes this equipment be full of vitality.But the spiral screen casing processing difficulties of this equipment, when constituting as usefulness plane sieve plate, number of screen decks reaches hundreds of, and this brings difficulty for the processing of equipment and the replacing of screen cloth.

Because there is such-and-such deficiency in existing equipment at present, cause the sieve classification equipment that constitutes closed circuit grinding with grinding machine to be still spiral classifier and cement cyclone, therefore development is efficient, and can constitute closed circuit automatically fine sizing equipment with grinding machine is the heat subject in domestic and international material screening classification field always.

The design's purpose is that it is little to wear and tear for the fine sieve classification provides a kind of efficient height, is difficult for stopping up, and production capacity is big, can be closed circuit automatically with grinding machine, and strict Vibration cylinder water sieve by the physical dimension sieve classification.

The utility model is to realize by following technical scheme.

Fig. 1-6 is the design's a composition structure chart, and it mainly is made up of tubular sieve 1, supporting device 2, transmission system 3, vibrating device 4, water tank 5, mineral-feeding pipe 6 and oversize drain tank 7.There is supporting collars 10,11 at tubular sieve two ends with design on flange 8,9 connections, the flange 8,9, the supporting collars is connected on the roller rack 22 by carrying roller 12, roller rack 22 is supported on the water tank 5 by spring 13, design has a belt pulley 14 on the flange 9, and motor 15 connects with belt pulley 14 on the flange 9 by decelerator 16.Vibrating device 4 is made of vibrating motor and support, and vibrating motor is selected vibration frequency according to the granularity of screening material, adopts intermediate frequency during more slightly material screening, during the fine screening, adopts high frequency.The tubular sieve adopts horizontal installation, the angle β of its axis and horizontal line is 0-45 °, the tubular lower part of screen places the water of water tank 5, water logging there is not the degree of depth of tubular sieve to be no less than 1/4th of its diameter, the design of tubular sieve inner surface has the dividing plate 17 of equidistant installation, angle α between this dividing plate and the tubular sieve radius is 0-75 °, (height of dividing plate 17 designs according to the quantity greater than screen size in the feed, requirement is less than 1/3rd of radius), mineral-feeding pipe 6, to the even groove 19 that divides in ore deposit, discharge trough 7 is fixedly connected on on the discharge trough bolster 18, bolster 18 is fixed on the water tank 5.

The tubular sieve can be columnar, also can be polygonal tubular, and screen cloth can be selected silk screen, expanded metals for use, also can form with the steel plate punching.

The tubular sieve is under the drive of motor, decelerator, slowly run with speed less than critical speed (42.3/D), material to be sieved feeds by feed pipe 6 from the material feeding end of tubular sieve 1, and the material that enters in the tubular sieve is assigned to the inside that tubular is sieved uniformly under the effect of the even branch of feed groove.Material less than sieve aperture enters in the water tank by sieve aperture under the vibration effect of vibrating device, gets rid of from the screenings outlet 21 of water tank bottom.Material greater than sieve aperture can not pass through sieve aperture, under the effect of tubular sieve inner surface dividing plate 17, rotates with the tubular sieve, falls into the oversize drain tank after being thus lifted to certain altitude, gets rid of from tubular sieve mine-discharging terminal by oversize drain tank 7.

The design possesses following characteristics:

1, device structure is simple, and requirement on machining accuracy is not high, and cost is low.

2, sieve classification efficient height can reach 90%.

3, sieve aperture is difficult for stopping up.The screening of material is carried out in water, the rotation of water, and effect such as lubricated has prevented the obstruction of sieve aperture; The vibration of vibrating device has also prevented the obstruction of sieve aperture, strengthens sieving of material simultaneously; The tubular sieve rotates, when compass screen surface is in low level, and a sieving actoion, when compass screen surface is in a high position, reverse side during just in time with the screening material, the vibration of this moment and rinse water have played the effect of cleaning, guarantee that it all is unimpeded entering the compass screen surface that sieves the district at every turn.

4, the do not sieve automatic castering action of material.Material less than sieve aperture becomes undersize by sieve aperture, screened material is not then under the effect of tubular sieve inner surface dividing plate, be raised with the rotation of tubular sieve, after arriving certain height, fall in the oversize hopper and discharge, reached the purpose that the oversize material promotes automatically in the effect of rinse water.

5, the screen cloth wearing and tearing are little.Screen cloth is when the screening material, and compass screen surface immerses in the water, and water reduces the impulsive force of material to compass screen surface to the suspension effect of material, has also alleviated the weight of material on the compass screen surface greatly, thereby reduces the wearing and tearing of compass screen surface; The rotating speed of tubular sieve is low, generally at 1～10 rev/min, vibratory sieve with routine, sieve bends etc. are compared by the screening machine compass screen surface that material impacts continuously, the time that the design's compass screen surface is impacted by material have only these compass screen surfaces by the attack time 1/3 in addition few, the life-span of this compass screen surface also exceeds more than 3 times than the screening machine of routine with regard to the time of being impacted.
