Description

Multiposition equi-speed aeration mixer

The utility model relates to a kind of multidigit with speed inflation mixing plant, is the special equipment of the energy-conservation building material made of production porous, belongs to construction material production equipment field.

At present, the method and apparatus of the energy-conservation building material made of production porous mainly contains following several in China's building material industry: a kind of is to adopt aluminium matter foaming agent slip is got angry and to stir and obtain porous article through chemical method.Though this method does not have specific (special) requirements to mixer, the condition of getting angry harshness; As: need degreasing in advance, and the environment temperature of foaming must be controlled at 43 ℃ ± 2 ℃ etc.Production technology is restive; Have aluminium matter foaming agent to cost an arm and a leg again, and raw material supply is in short supply often, so, still have a considerable amount of factories to fail ordinary production so far though promote through for many years; Another is that foaming agent is made foam in advance, and secondary mixes stirring and makes the energy-conservation building material made of porous with clean slip again.This method needs multiple mixing plant, and production technology and control of product quality are comparatively complicated, easily influences the stability of goods; Also have a kind of by while inflating rotation stir the slip be furnished with foam stabilizer and the method and the relevant device of production porous energy-conserving product, this equipment is referred to as rotation inflation self-overflow type mixer, it is mainly constructed and sees accompanying drawing 1.The operation principle of this method and process are such: at first start air compressor (4) and power drive system (5) is pressed into compressed air from motionless air inlet pipe, and enter inflatable chamber (2) and inflation medium (3) by the hollow spindle (1) that rotates, when hollow spindle (1) rotation and drive inflatable chamber (2) and inflation medium (3) when its axial line rotates jointly, compressed air sees through the micropore permeation of inflation medium (3) in the slip of mixing drum (6), so continuous stirring makes the slip of being furnished with foam stabilizer form more tiny and uniform pore, and the slip that stirs is from flash Overflow, and charging aperture advances virgin material continuously, just formed continuous production.Though this method is without foaming agent or blowing agent, production technology is simple, and equipment is required height, and have following point: (1) inflatable chamber area is big, and stressed concentrating in the chamber is so require high to the manufactured materials and the air-proof condition of inflatable chamber; (2) make concentric circular tracks and move because of drives inflatable chamber and inflation medium by hollow spindle rotation, make limit, heart mixing speed inconsistent, and easily cause the layering of foam slip; (3) serve as the arm of force and do rotation on a large scale because of inflatable chamber and inflation medium, make it stressed bigger, damaged easily, need frequent repair and replacement, more difficult raising rotating speed and strengthen radius of turn, thus influence production efficiency and quality; (4) also because of the inflation medium wall thickness and below the too little 10um of lip-deep micropore size, easily stopped up by slip, thereby both reduced charging efficiency, influence the service life of inflation medium again, material therefor PVC price is more expensive, and cost is higher.At above-mentioned phenomenon and problem, we have proposed a kind of novel inflation mixing plant.

The purpose of this utility model is exactly to provide a kind of novel multidigit with speed inflation mixing plant, it can realize effectively, reliably that limit inflation, limit multidigit are with turn round stirring fastly, make the slip of being furnished with foam stabilizer produce fine uniform air hole structure, make the energy-conservation building material made of high-quality porous through maintenance, and replacement aluminium powder and other blowing agent, additives and equipment, thereby simplification technology reduces cost.

The purpose of this utility model is achieved in that air compressor constantly is pressed into compressed air in the monoblock type rigidity inflatable chamber that constitutes by threading a pipe mutually, and rigid attachment is made in the arbitrfary point on the pipeline of inflation medium and inflatable chamber, when the drive of the bent axle in transmission system inflatable chamber integral body is done the plane rotation motion, each inflation medium is done multidigit with fast non-concentric circular tracks motion among a small circle, thereby the slip of being furnished with foam stabilizer around making produces even, fine and smooth micropore, and obtains the energy-conservation building material made of porous.

The utility model is because of adopting while inflating the energy-conservation goods of stirring method production porous, foaming of aluminium matter blowing agent chemical gas generation and stirring method and use foaming agent and secondary stirring method have been substituted, thereby simplified production technology, reduce production cost, alleviated the contradiction of aluminium powder raw material supply anxiety; Be source of the gas because of adopting compressed air again, the serviceability temperature wide ranges, 0 ℃-50 ℃, low to the environmental condition requirement, production process is grasped easily and is controlled, constant product quality, the yield rate height is so have very strong applicability and positive dissemination; Constitute monoblock type rigidity inflation pipe support because of adopting to thread a pipe mutually again, and replace the monoblock type inflatable chamber, cavity pressure is disperseed relatively, thus improved inflatable chamber service life, reduced requirement to material and air-proof condition; Do the plane rotation motion because of adopting crankshaft rotating and driving the inflation pipe support again, and make each inflation medium do plane rotation relatively independent, that multidigit is fast together, but not concentric circles rotates, thereby make each inflation medium movement velocity unanimity, stir, prevent the slurry layering, improved product quality; Because of adopting said structure, each inflation medium range of movement is dwindled relatively, and reduced resistance and the wearing and tearing that act on inflatable chamber and the inflation medium, thereby prolonged their service life again, also can corresponding raising rotating speed, boost productivity; Because of the micropore size on the inflation medium strengthens, reduced the obstruction probability again, above-mentioned advantage has further been strengthened.
