Abstract
Provided is a multistage wet process screening system and a screening method. The screening system comprises a wet process production screening device. A pre-spray chute is arranged in front of the screening device. A slow down piece is arranged inside the pre spray chute. A feeding tape machine is matched with the pre spray chute. A spraying device is arranged on the front part of the feeding tape machine. A vaporific environment is arranged on the front part of the feeding tape machine, water content of materials is increased, and the affinity degree of water and small materials on the surface of raw materials is increased in the process that sandstone is carried by the tape machine. Turbulence and collision of building stones are avoided in tape transport process. Affinity with water and predissociation with the raw materials are accelerated. With the pre spray chute arranged in front of the screening device and the arranged slow down piece, the effects of soak drop friction and scrub are achieved. When the multistage wet process screening system and the screening method conduct wet process screening, too much equipment and devices are not needed. Three-stage wet process screening is used, and a shape varying stone washing process is added in the front stage of an ordinary screening washing process, drainage in the process is all focused on a screen surface, and drainage equipment is not added and a screening effect is good.
Description
Technical field
The present invention relates to aggregate screening technical field, be specifically related to a kind of multisection type wet sieving system and method for sieving.
Background technology
Up to standard for ensureing sandstone finished product material clay content, the sandstone of the system of processing of sandstone needs to rinse sandstone before entering vibrating screen classifier.For ensureing rinsing quality, the flushing pore that control to sieve flushing surface is arranged and uses water pressure.Its water consumption is the total water consumption more than 90% of wet production Preservation for Aggregate Production System.The common group of being mixed with in sandstone raw material, when being mixed with walk in screening raw material, even if wash institute's cloth pore to vibratory sieve machine side upper punch, increasing water pressure, increases water consumption, goes walk effect not remarkable, after sieve, material has and still has walk, directly affects end product quality.Need soak through stone scrubber, wash by rubbing with the hands, can walk be removed, obtain clean aggregate.Right mudstone acc power is large, and installation dimension is large, and equipment manufacturing cost is high.Conventional stone scrubber, also can only process the material being less than 40mm.
Summary of the invention
Technical problem to be solved by this invention is to provide one effectively can control water consumption, how under the condition of satisfied production, reduces and sieves and washes the water yield, energy-saving and cost-reducing stage wet method screening system and method for sieving.
The object of the present invention is achieved like this: a kind of multisection type wet sieving system, comprise wet production screening plant, arrange and spray chute in advance before screening plant, in pre-spray chute, configuration delays to fall the ridge, feed sealing-tape machine with in advance spray chute and match, at feed sealing-tape machine leading portion, sprayer unit is set.Material sealing-tape machine head is provided with sweeper.Be provided with nozzle in pre-spray chute, nozzle is distributed in outside pre-spray chute.
A method for syllogic wet sieving sandstone, comprises the following steps:
1) start sprayer unit, form vaporific space at feed sealing-tape machine feed end, make the sandstone water content entering feed sealing-tape machine bring up to 0.5% ~ 1%, infiltration is played to material and to rub stranding effect;
2) sandstone improving water content by vaporific space enters and sprays chute in advance, sprays chute in advance, the nozzle spray in pre-spray chute, improves sandstone water content further and bring up to 1% ~ 10%; Immersion is played to material and falls friction, wash effect by rubbing with the hands;
3) sandstone that water content is qualified enters into wet production screening plant, completes screening.
Provided by the invention kind of multisection type wet sieving system and method for sieving, vaporific environment is established at feed sealing-tape machine leading portion, increase the water content of material, improve sandstone in sealing-tape machine carry process, the affinity degree of the little material of water and raw material surface, avoid in Belt transport process, building stones jolt collision, accelerate with water affinity and with raw material pre-separation; Arrange before screening plant and spray chute in advance, configuration delays to fall the ridge, improves sandstone water content, and the present invention, when carrying out wet sieving, does not need to increase too much equipment.The walk producing and remove in sandstone can be had by the present invention, no longer need stone scrubber, simplify and wash technique, reduce production cost.This syllogic wet sizing process effect of stone effect, the common screening developing technique leading portion that coexists is set up simple and easy remodeling and is washed lapicide's skill, and the draining in technique all concentrates on compass screen surface, does not increase pumping equipment, and screening effect is good.Carry out pre-flush technique; Do not set up equipment, only set up water supply process pipeline.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the layout of equipment of the present invention.
Detailed description of the invention
Apparatus structure of the present invention as shown in Figure 1, comprise wet production screening plant 3, it is characterized in that: before screening plant 3, arrange pre-spray chute 2, in pre-spray chute 2, configuration delays to fall the ridge, feed sealing-tape machine 1 with in advance spray chute 2 and match, at feed sealing-tape machine 1 leading portion, sprayer unit is set.Material sealing-tape machine 1 head is provided with sweeper 4.Be provided with nozzle in pre-spray chute 2, nozzle is distributed in outside pre-spray chute 2, avoids material impact.
Utilize device of the present invention to carry out the method for syllogic wet sieving sandstone, concrete steps are as follows:
1) start sprayer unit 5, form vaporific space at feed sealing-tape machine 1 feed end, make the sandstone water content entering feed sealing-tape machine 1 bring up to 0.5% ~ 1%; Will note adjustment sealing-tape machine head cleaner 4 in process of production, appended by will returning under layer on adhesive tape, material removing is in head funnel.
2) enter pre-spray chute 2 by the sandstone of vaporific space raising water content, spray the nozzle spray in chute (2) in advance, improve sandstone water content further and bring up to 1% ~ 10%; In this segment process, sealing-tape machine delivery is complete, in sealing-tape machine head funnel chute dropping process, the initial kinetic energy of material, under gravity, and the impact between the impact of funnel chute and material and friction, increase the power of being washed of material and washed length of run, storing type chute has pre-soaking function concurrently.
3) sandstone that water content is qualified enters into wet production screening plant 3, completes screening.
