Abstract
The utility model relates to the field of building material manufacturing equipment and in particular relates to a mechanical sand production system. The mechanical sand production system comprises a sand making machine, wherein the sand making machine is provided with a feed hole and a crushing cavity, and the crushing cavity is connected with a powder extraction pipeline. In the mechanical sand production system, all or most of stone powder produce in the sand making machine is extracted by the powder extraction pipeline as the crushing cavity of the sand making machine is connected with the dust extraction pipeline, so that stone powder is avoided being mixed in the sand making machine and mechanical sand is free of a follow-up powder-removing process, therefore, the production cost of mechanical sand is reduced.
Description
Technical field
The utility model relates to building materials producing apparatus field, particularly relates to a kind of Machine-made Sand production system.
Background technology
In Process of Engineering Construction, sandstone is as the important component part of concrete structure material, and quality and the weather resistance of its quality good or not on whole engineering has very important impact.Under the prerequisite meeting by sand performance index, select economically viable scheme, should meet construction quality requirement, effective production control cost again, like this in the area of natural sand resource shortage, Machine-made Sand is undoubtedly optimum selection.
Machine-made Sand refers to the sand processing by sand machine processed and other auxiliary facility.After soundness and endurance test, find carrying out, although the firm performance of Machine-made Sand is slightly poorer than river sand, can reach premium grads index completely, in normal concrete, use any problem that do not exist.
Machine-made Sand has three leading indicators to receive much concern in application: powder containing quantity, crush index and fineness modulus.Machine-made Sand in process of production, is inevitably accompanied with the stone flour that a small amount of particle diameter is less than 0.08mm.According to natural sand quality standard, be less than 0.08mm particle and be defined as mud, and the content restriction of mud is strict, in the time that content of stone powder is higher, there is disadvantageous effect to configuring concrete intensity.
But, mostly current production unit is screening plant coordinating for crusher and with crusher etc., but screening plant only can shine the excessive gravel of particle diameter, but cannot effectively sieve stone flour, this just causes the Machine-made Sand processing need to could use through follow-up deep processing toward contact, or brings disadvantageous effect to the quality of building after directly using.
Summary of the invention
The purpose of this utility model is to provide a kind of Machine-made Sand production system of the content of stone powder that can reduce Machine-made Sand, to reduce the production cost to Machine-made Sand.
In order to address the above problem, Machine-made Sand production system of the present utility model by the following technical solutions: Machine-made Sand production system, comprise sand machine processed, sand facility processed have opening for feed and crusher chamber, described crusher chamber is connected with dust suction pipeline.
One end away from crusher chamber of described dust suction pipeline is connected with fly-ash separator.
Fly-ash separator is electronic impulse fly-ash separator.
Between dust suction pipeline and sand machine processed, flange is connected.
Also comprise for the feeding device to sand machine input processed sandy plain material processed.
Described feeding device is belt-type feeding device.
On described dust suction pipeline, be serially connected with dust stripper.
Described dust stripper is cyclonic separator.
In this Machine-made Sand production system, because the crusher chamber of described sand machine processed is connected with dust suction pipeline, therefore, in sand process processed, the stone flour producing in sand machine processed is all or at least most of to be extracted out by dust suction pipeline, thereby can avoid it to be mixed in Machine-made Sand, make Machine-made Sand can avoid follow-up gumming processing, and then reduced the production cost to Machine-made Sand.
Further, fly-ash separator can be used for collecting stone flour, can reduce pollution on the one hand, is also convenient on the other hand the later use to stone flour; Dust stripper can further be distinguished the ducted dust of dust suction, thereby the dust of different grain size grade is further separated, and then facilitates follow-up use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of Machine-made Sand production system.
Embodiment
The embodiment of Machine-made Sand production system, as shown in Figure 1, this system comprises feeding device 11, sand machine 12 processed, dust pump-line 13, dust stripper 14 and fly-ash separator 15.
What feeding device adopted is belt-type feeding device, is specially charging belt machine, has upwards of movement large, safeguards easy characteristic, is widely used in excavation, metallurgy, coal and building material industry, and it is in the present embodiment for sand machine material loading processed.
Sand machine processed claims again vertical impact crusher, and it has opening for feed and crusher chamber, for material fragmentation (sand processed).The structure of vertical impact crusher is prior art, it has adopted a kind of middle impeller that can form building stones liner of producing, when work, this impeller is as the dry type building stones pump of same high speed rotating, constantly impelling of building stones is entered in crusher chamber, crusher chamber has a variety of structure configurations, to adapt to different operating modes, as: the crusher chamber that counterpunch board is housed is adapted to most of materials; For the very strong material of abrasiveness, in crusher chamber, generally do not fill counterpunch board and form material from lining, etc.The building stones that feed from machine its top feed mouth are accelerated in impeller, and while leaving impeller outlet, speed can be up to 60～85m/s, and impeller ceaselessly enters crusher chamber by building stones impelling.In this process, building stones and building stones, building stones and counterpunch board clash into mutually, and because stroke speed is very high, material is along its natural texture face fracture, and particle shape is cubes, and elongated particles is low.
Dust suction pipeline, for conveying and the sealing of dust, is formed by steel pipe and Plate Welding.
What dust stripper adopted is cyclonic separator, and the high velocity air (containing dust) in dust suction pipeline can high speed rotating after entering the separator cartridge of cyclonic separator.Because direction of motion sharply changes, channel cross-section expands, and air flow slows, so the larger particles (can be used for regulating the grating of sand) in air-flow just falls, slides into fine sand outlet along cyclone cylinder inwall and discharges; And less dust cannot be deposited in cyclone cylinder internal recycle, under the effect of air-flow, enter the further dedusting of pulse dust collector, purifying treatment.
What fly-ash separator adopted is electronic impulse fly-ash separator, this dust-removal system adopts two-stage dust removal to purify, first step expanding, second stage electronic impulse sack cleaner (jet---pulsed technique), one-level expanding fly-ash separator inlet mouth is connected with the crusher chamber of sand machine processed by dust suction pipeline, dust-contained airflow is tangentially entered in expanding dust settling chamber with higher speed by inlet mouth, because the dust-contained airflow of high-voltage high-speed enters in expansion dust settling chamber, air expands suddenly, gas velocity slows down suddenly, under the effect of centrifugal force, larger particles dust is assembled to bucket wall, under the squeezing action of follow-up air-flow, continue downward sedimentation, after extending to bottom, cone enters screw machine by casing, pure qi (oxygen) is turned back, and upwards (dustiness is at 30g/m
3left and right), enter secondary electrons pulse bag type dust collector decontamination chamber, then dusty gas enters in the filtration chamber that filter bag is housed.Dust is attached to filter bag outside surface, and purified gas enters upper box body by filter bag, then enters in atmosphere and go through high pressure blower pipeline.
