Description
One, technical field:
The present invention relates to a kind of plant equipment, specifically is a kind of foaming machine of making foamed bricks, belongs to building materials and makes the field.
Two, background technology
Foaming machine is a kind of equipment of producing foamed bricks, and its effect is to produce foam, afterwards these foams and slurry Forced Mixing is stirred, and foam is entered form bubble in the slurry, finally makes foamed bricks.
The basic principle of foaming is introduced air in the foaming agent solution exactly.Foam be formed with two important factors, the one, foaming agent solution, the 2nd, air, Neither of the two can be dispensed.Do not have foaming agent solution, the liquid film that surrounds gas just can not form, and does not just have bubble yet.And do not have gas, and single-shot infusion solution, bubble can not form.In the system that bubble forms, foaming agent solution is a decentralized medium, and gas is decentralized photo, and gas dispersion could form bubble in liquid, form foam by countless bubbles again.Except this key factor of blowing agent performance, it is the important factor of another one that gas is introduced foaming agent solution.And gas is introduced liquid, must finish by foaming machine, and promptly foaming machine adopts certain method that gas is introduced in the liquid.Different foaming machines is introduced the method difference of gas.
Generally speaking, the method that existing foaming machine is introduced gas has: 1, rotating vane is introduced gas at a slow speed, be that a kind of direct introducing is mixed with the method in the mortar (or concrete grout) of blowing agent, the defective that the method exists is that the rotary speed of blade gas slow, that introduce is few, so the bubble growing amount is little, foaming effect is not good enough, and efficient is lower.2, high speed rotational blade is introduced gas, and this is a kind of mode that relies on high speed rotational blade to introduce gas in foaming agent solution, and the active force of rotating vane is mainly leaned in the introducing of its gas.Basic principle is when impeller rotates at a high speed, and the foaming agent solution that drives in the foaming tube rotates thereupon, forms the circulation of a rolling, and produces a very big vortex.At this moment, be positioned at the gas-liquid two-phase particle of foaming agent solution top gas-liquid interface, will accompany and descend, be the bottom that quick helical form drops to vortex,, produce bubble thereby form a turbulent area from 2.5～5cm place, impeller edge.Shortcoming is that the mode of liquid bleed is slow and inhomogeneous, and bubble diameter is big, and particularly bubble diameter is uncontrollable, relies on the randomness of foaming machine fully, can't guarantee that bubble diameter and foam are even.3, utilize pressure to introduce gas, this is the bleed foaming mode of generally using domestic and international present stage, also is the comparison science, and cardinal principle is to utilize the various equipment that can produce air pressure, and air is pressed in the liquid phase, realizes the even mixing of two-phase.Under normal pressure, air enters liquid than difficult, and under certain pressure, then becomes than being easier to.This air pressure singly is not that gas is pressed in the liquid, liquid is pressed in the gas simultaneously yet, and actual is that two-phase is exerted pressure simultaneously.Like this, the mixing of two-phase is will speed fast, efficient is higher, even, bubble is less, has reached the more satisfactory effect of foam, but still has blowing agent insufficient phenomenon that foams.4, high-pressure spray is introduced gas, and basic principle is that the powerful dispersion force of utilizing jet to produce realizes that gas phase contacts with liquid phase big surface of moment, makes the two even mixing, and wraps up in gas formation foam with liquid.This method is state-of-the-art at present, also is that effect is best, can still have a lot of places to need to improve.
Three, summary of the invention
The purpose of this invention is to provide a kind of novel foaming machine, the foam bubble diameter of this foaming machine preparation is even, and foam stability is good, and bleeding rate is low, and another object of the present invention is the foam that can quantitatively distribute.
To achieve these goals, the foaming machine of making foamed bricks of the present invention, it is characterized in that: it comprises housing and is located at housing interior agitator arm and injection apparatus, described agitator arm is driven by external motor, the coaxial forward direction that is arranged on agitator arm of injection apparatus, injection apparatus comprises by the outer water lines that inserts of housing, blowing agent pipeline and high pressure airline, the water lines spout is vertical with the surfaces of revolution of agitator arm with the blowing agent spout, between water lines spout and blowing agent spout, be provided with the pressure-air spout and be used to import pressure-air, be provided with the outlet of foam in lower housing portion.
On water lines, blowing agent pipeline and high pressure airline, quantity control valve is housed, is used to regulate the ratio of water, blowing agent and the pressure of pressure-air, be used to produce the foam and the foam volume of different-diameter.
The scheme of sort this problem out of the present invention is: by pipeline blowing agent and water are injected in the housing, the injection of pressure-air is to adopt high-pressure spray to introduce the gas mode to generate foam, its powerful dispersion force of utilizing jet to produce realizes that gas phase contacts with liquid phase big surface of moment, make the two even mixing, and wrap up in gas formation foam with liquid.Remaining afterwards Puiescent, inoperative blowing agent stirs through impeller again, then is to have adopted rotating vane to introduce the gas mode to produce foam.In addition, because gases at high pressure enter housing, in housing, form certain superpressure, utilize pressure to introduce the gas principle so again and produced foam, foam mixes with slurry by a certain percentage through single valve and quantitative supply device of pressing, and mixes in fixing impeller stirring pipe and very abundant, by outlet output, be poured into in-mold molding again.
Advantage of the present invention is:
1, the foam of Chan Shenging is with the both direction adverse current, and stable back foam bubble diameter unanimity is between Φ 0.2mm～0.5mm.
2, blowing agent under high pressure is foamed into foam by agitator arm, and subsequent processing is that foam is forced to inject the flyash slurry, and require the foam in slurry to distribute very evenly, this is the key of producing qualified products, otherwise product density, the unequal defective of intensity can occur.This process is under high pressure to inject, and is provided with the agitating auger that leaves standstill in the carrier pipe, and slurry and foam around the agitating auger rotation of leaving standstill, so just can reach good effect in pipe.
Foaming machine of the present invention is to introduce the combination that gas and high-pressure spray introducing gas and pressure are introduced three kinds of modes of gas in conjunction with high speed rotational blade, it has eliminated the defective of four kinds of foam producing methods in the background technology, it is fast to have reached the bleed mode, foam is evenly tiny, the bleeding rate height, the advantage of good stability; The blowing agent utilization rate is very abundant, and water and blowing agent can enter by certain quantitative ratio, and so neither can waste water can not waste blowing agent yet, material utilization rate height.
