Description
Technical field:
The present invention relates to the mixing instrument of a kind of cement-based material gradient.
Background technology:
Cement-based material is as the construction material of consumption maximum, is that very big effect has been brought into play in the improvement of human civilization and living conditions in 20th century, also can't see the sign that is replaced by other material in following 100 years.Cement-based material has advantages such as raw material sources are wide, with low cost, convenient processing and manufacture, compression strength height, good endurance, but also exist tensile and compressive strength than shortcomings such as low, function singleness, poor toughness simultaneously, suppress its purposes widen and act on give full play to.The proposition of function-graded material notion provides a new way for the material that preparation has complex function, specific function or good mechanical property.At present, function-graded material all comes true in fields such as meticulous function ceramics, metal/ceramic composite, metal alloy compositions.But because the particularity of cement-based material (cement concrete) structural constituent and forming method does not have the equipment that is applicable to the cement based function-graded material at present as yet.The forming method of pottery, metal constant gradient functional material, can't be used for the production moulding of cement-based material at the method for precisely forming of atom, molecular level as ion sputtering method, chemical vapor deposition method etc., the forming method of tradition cement concrete material can't realize all that as methods such as artificial stirring moulding, mechanical agitation vibration moulding, roll-formings material component is changed continuously by the gradient of goods (member) side to opposite side.The manual zoning prepares burden, the prepared cement based functionally gradient material (FGM) of process of layering moulding comes down to component and is stepped change and adopt, and does not solve the problem that the component continuous gradient changes.In theory, adopt artificial unlimited multi-segment batching layering moulding, the class continuous gradient that can reach component changes.But because forming process numerous and diverse, speed is too slow, can't realize in the practice.
Summary of the invention:
The purpose of this invention is to provide among a kind of preparation technology who is applied to the cement based function-graded material, control the mixing instrument of cement-based material gradient that each component feeding system solves component continuous gradient distribution problem in cement-based material preparation by computer program.
In order to solve the continuous gradient variation issue of cement-based material component, the present invention has designed the mixing instrument of a kind of cement-based material gradient, controllable continuous by three component feeding systems changes feed, has realized that the continuous gradient of each component of cement-based material changes, and has obtained effect preferably.
The technical solution adopted in the present invention is: the mixing instrument of a kind of cement-based material gradient comprises vertical agitator, the mixing storehouse of level, flow regulator and two above Storage appts.s; Each Storage appts. is made up of hopper, variable frequency induction motor, change-speed gearing, screw feeder and tremie pipe, screw feeder and hopper UNICOM, and the upper end and the screw feeder of tremie pipe link, and lower end and vertical agitator link; Puddler is housed in vertical agitator, on puddler, has paddle, the following outlet of vertical agitator and the mixing storehouse of level UNICOM; Above the following outlet side of vertical agitator, be provided with flow regulator; Flow regulator is made up of high-pressure water pipe, dispersive nozzle and flow control valve.
Angle a＜90 of paddle and puddler °, with horizontal direction angle β＜5 °.
Adopt three component continuous feeding systems, wherein three kinds of solid phase components are by computer program-control, and liquid is controlled separately by the adjustable flow meter, and guarantee two parts synchronous working.Three kinds of solid phase components, according to its unit weight by speed change spiral stirring blade speed change feed in time under computer (set initial velocity and final speed) control.Moisture is sprayed into by three alternate 120 ° dispersive nozzles with atomised form before stirring afterwards, mix at solid material.Agitating device adopts leafy vertical shaft and housing to form (paddle and puddler angle α＜90 °, and horizontal direction angle β＜5 °), material vertical drop under the gravity effect of confessing by feeding device, realize instantaneously puddling for the first time through the agitator of at a high speed rotation, the spiral that drops at the uniform velocity rotation mixes and stirs cutter and water mixes.The device horizontal positioned of mixing is made up of spiral stirring blade and close-fitting housing.For mixing evenly, spiral stirring blade should have enough length.Material after mixing directly enters mould by distributing device, implements to keep original gradient distribution of its each component constant, extrusion forming behind vibration moulding or the cloth immediately along products thickness direction cloth.
Advantage of the present invention and effect are: the continuous gradient of having been realized component by the component continuous feeding system of computer program-control changes, and is applicable to that the gradient function concrete of small particle diameter aggregate is cut fortifying fibre or short production of cutting functional fibre cement based complex gradient functional material goods with lacking.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the vertical agitator structural representation.
The specific embodiment:
Accompanying drawing 1. has provided structural representation of the present invention, and arrow is represented the Flow of Goods and Materials direction among the figure.Accompanying drawing 2 has provided the structure of vertical agitator.
The course of work of the present invention:
A certain amount of cement, aggregate (sand) and chopped strand (surface treated carbon fiber) are put into three storage bin(hopper)s 1 respectively, under the gravity effect, fall into variable frequency induction motor 3 by the computer control transient speed, the screw feeder 4 that drives through change-speed gearing 2 feeds vertical agitator 6 through tremie pipe 5, (puddler 7 is that the ac three-phase asynchronous motor 13 by main controller 17 controls drives through belt 9 at the puddler 7 of gravity and at a high speed rotation (1400r/min) and paddle 23 to enter material in the vertical agitator 6,12 is the belt pulley protective cover) stirring under, rotation is fallen.Angle α＜90 of paddle 23 and puddler 7 °, with horizontal direction angle β＜5 °, material falls to 7 times 1/3rd chances of puddler and is carried through high-pressure atomization water flow regulator 15 meterings and 14 atomizings of process dispersive nozzle by high-pressure water pipe 16, under the stirring of puddler 7 spiral drop to the mixing storehouse 8 of level (the mixing spiral stirring blade 18 in the mixing storehouse 8 of level be by the ac three-phase asynchronous motor 11 of the main controller on the workbench 20 17 control through belt 9 drive and by change-speed gearing 10 speed changes), material is mixing and promote evenly to be distributed into the mould 21 that places on the shake table 22 by distributing device 19 through the rotation of mixing spiral stirring blade 18.Material is through vibration closely knit voluntarily (material also can be repressed closely knit after being covered with grinding tool).Material after closely knit (goods) enters the goods fog room with mould (after the demoulding of compacting goods), and maintenance is the finished product (present embodiment is that spontaneous heating is from the temperature control wallboard) that needs to the length of time of stipulating.
For guarantee mixing spiral stirring blade 18 life-span, spiral stirring blade must be by the hard alloy steel manufacturing, the pitch of spiral stirring blade and tooth depth are not less than three times of maximum aggregate size.Spiral stirring blade also must closely cooperate with its shell.
