Description
Technical field
The present invention relates to a kind of air sieve, particularly relate to a kind of dry type Machine-made Sand air sieve.
Background technology
In Process of Engineering Construction, sand is as the important component part of concrete structure material, and its quality good or not has very important impact to the quality of whole engineering and durability.Under the prerequisite of satisfied sand performance indications, select economically viable scheme, construction quality requirement should be met, production control cost effectively again, like this in the area of natural sand resource shortage, employment mechanism sand carries out concrete construction production and is not only feasible, and its comprehensive benefit is also significant.Simultaneously in Machine-made Sand uses, also can carry out the development test of construction material subject aspect, accumulate experience, for foundation stone is established in the development of subject.
Machine-made Sand refers to the sand processed by sand machine processed and other auxiliary device, and finished product is more regular, can require the sand being processed into different gradation specification and size, more can meet daily demand according to different process.Machine-made Sand will have the equipment of specialty just can make qualified applicable sand.
The equipment such as Machine-made Sand production line has oscillating feeder, disintegrating machine, vibratory sieve, air to sieve, companion wet machine, deduster, powder tank and adhesive-tape machine combine.According to different technological requirements, the equipment of various model combines, and meets the different process requirement of client.First, building stones carry out preliminary fragmentation by boulder crusher, then, the coarse fodder produced is delivered to fine crusher by rubber conveyer and carries out further fragmentation, building stones after in small, broken bits enter Vibration Screen and separate two kinds of stones, meet the stone system sand Machine-made Sand of sand machine feed size processed, another part returning charge thin broken.
Air sieve is as the nucleus equipment in existing dry type Machine-made Sand production process, there is huge market demand, the air sieve of Kotobuki Engineering & Mfg. Co Ltd of Japan represents the level of current world advanced person, the said firm is the patent of CN101795774A at the notification number that China applies for, not being both of the 1st sorting unit described in its accompanying drawing 1 and the design that we do maximum (or crying significantly, or be key):
(1) material of this sorting unit is entered without sieving in advance, the material of more than granularity 4.75mm also enters sorting unit together, screen cloth is provided with in sorting unit, the material of more than granularity 4.75mm is discharged by foldback road after adjustment plate and screen cloth are separated out, directly cause device structure complicated, material is little through the throughput of screen cloth, and production capacity cannot improve.
(2) material enters in body does not have disperser, and directly cause material to fail fully to spread, separating effect is poor, the dust containing a large amount of below 0.075mm in the material that Ji Shakou flows out.
And the selling price of above-mentioned complete equipment more than 1,000 ten thousand yuans, price is extremely expensive, and common customer cannot accept such price! Also there is the shortcoming that disposal ability is very low, only have the applying unit (as: nuclear power sand) of minority state-owned enterprise and specific use to use at present, the market demand that domestic infrastructure sand using amount is huge cannot be met at all, and the demand of numerous sandstone manufacturing and processing enterprise.
Through us years of researches and test, find that current existing air sieve also exists production disposal ability little, complex structure, the shortcomings such as buying and use cost height, especially vibration screen is built in air sieve in existing air sieve, cause the maximum bottleneck improving throughput and production capacity, production capacity is directly caused to improve, if existing air sieve will be enhanced production capacities, so to reach conventional production capacity, the volume of the air sieve single product of built-in screening wire will have the size in a house, the production of little micro-throughput can only be met, the demand of the numerous sandstone manufacturing enterprise of Chinese market can not be met completely.
Summary of the invention
(1) technical problem that will solve
