Abstract
The continuous fluid mixer includes the following members: inlet pipe, stator, casing, mixing rotor, driver and material outlet, and its stator, casing and mixing rotor are set coaxially. Each of the stator and the mixing rotor includes 2-20 layers of teeth in different diameters crossly arranged radially, and each of stator layers and rotor layers has 6-40 teeth. The angle between adjacent rotor teeth and stator teeth decreases gradually with the increasing stator layer and rotor layer diameters. The mixer can on-line mix continuously in high mixing efficiency.
Description
Technical field
The invention belongs to the mixer that has gyratory agitation device in fixed container, more particularly, is a kind of fluid continuous mixing device.
Background technology
In industries such as chemical industry, food, pharmacy, metallurgy, building materials, often need carry out on-line mixing with the two or more big colloids of viscosity to two kinds, the concentration of require mixing the back material is very even, wishes that simultaneously this equipment has little, the advantage such as online continuously of mixing efficiency height, energy consumption.
At present, liquid mixes with liquid generally all uses static mixer, and this hybrid mode is mixed liquid liquid, even, online, the continuous mixing of energy; Yet for colloid and colloid, colloid and liquid mixed system, if carry out on-line mixing with this static mixer, must select higher high-pressure pump of pressure or plunger displacement pump for use, thereby higher requirement is proposed for equipment, pipeline, energy also consumes bigger, cause blender, pipeline blockage easily, particularly for cream pasty state sticky material, difficulty is bigger; Thereby can't guarantee online, continuous mixing.For this material to this character generally adopts change can mixer, shears other batch mixers mixing such as excellent blender, double arm kneading mixer, the on-line continuous perhaps very big with power, that mixing efficiency is very low is mixed the machine that grinds and is mixed.
Change can mixer is relatively simple for structure, and cost is lower, uses widely in some noncontinuity hybrid techniques, as in paint production technology; And for example in producing, adopts solid rocket fuel the planetary change can mixer of high load capacity; Seal advantages such as tight though change can mixer has, there is discontinuous shortcoming in this equipment, can't carry out the serialization industrial production.
For another deciding the groove blender, shearing excellent blender, double arm kneading mixer etc. and all belong to above-mentioned discontinuous blender, though they have separately advantage in separately application, but for the continuous online production of colloid (particularly cream pasty state sticky material), these equipment are all inapplicable.And some equipment dynamic consumption is very big, has problem such as waste energy.
Certainly, in colloid mixes, some continuous on-line mixing equipment are arranged also, as single-screw extruder, double helix machine, Rietz extruder, the compound kneader of Baker Perkins etc., these equipment mainly are that colloid is carried, mediated, wherein also have immixture concurrently, but be not to be mixed into the master, more not have other effects such as fragmentation, homogeneous, when granularity in the raw material is uneven, just can't guarantee that mixed material is even; And some equipment dynamic consumption is very big, has problem such as waste energy.
CN1111166A is a kind of glue fat mixer, it belongs to a kind of online static mixer that is similar to screw rod, this mixed pole is longer, blade on the bar is four prismatic blades, the rotary speed of mixed pole is limited,, flowability general to toughness be glue preferably, and for example, the Combination of resorcinol phenol glue, phenol glue, urine formaldehyde resin adhesive etc. is better; Then must select higher high-pressure pump of pressure or plunger displacement pump for use if mix the very big slurry of toughness, thereby equipment, pipeline are proposed higher requirement, energy consumption is bigger; Also cause pipeline, blender mixture to stop up easily.More there are not functions such as fragmentation, homogeneous.Therefore strict especially to the requirement of charging, the granularity that requires when each raw material must be ground into the mixed material discharging.
CN1076885A and CN1134684A structural similarity, belong to plasticising, the continuous mixing and blending machine of plasticizing multiscrew, this structure is to utilize twin-screw, mainly be a kind of kneading, the mixed machine that grinds, it is to utilize engaged screw rod to mix under low speed to grind, the shape of the screw thread on the screw rod, spacing, screw thread etc. changes with axis direction, also screw rod is divided into material metering section, homogenizing zone, mixer, mixed problem such as grind that this equipment is suitable for those special sticky materials, material that water content is very low, and the mixing of several colloids is not fit to.
CN1307935A is a kind of shearing, strike, hole micronizer, it is made up of spindle (fixed ring), rotor (rotating ring), the gap is identical between each spindle and the rotor, the angle of each layer tooth is identical, yet material mix, in the crushing process internally the center move to the outside, material can be more and more thinner, if the gap is identical between each spindle and the rotor, material can reduce in the operating efficiency of mixing, crushing process ectomesoderm part tooth, can not give full play to the effect of outer tooth.
Summary of the invention
The objective of the invention is to provide on the basis of existing technology a kind of novel flow mixer that is applicable to the serialization industrial processes.
Flow mixer provided by the invention comprises with lower member: inlet tube 1, spindle 2, mixer case 3, mixed rotor 4, transmission device 5, discharging opening 8, wherein, the coaxial setting of spindle, mixer case and mixed rotor; Described spindle and mixed rotor all comprise the spindle tooth or the rotor tooth of 2-20 layer different-diameter, and described spindle tooth layer and rotor tooth layer radially being staggered along this blender; Described spindle tooth layer and rotor tooth layer all comprise 6-40 combination tooth, and along with the progressively increase of spindle tooth layer and rotor tooth layer diameter, the angle of adjacent rotors tooth and spindle tooth reduces gradually.
The invention has the advantages that: the present invention has continuously, the on-line mixing function, the mixing efficiency height, also have functions such as pulverizing, homogeneous simultaneously, can solve two kinds and the big liquid of two or more viscosity and mix with liquid on-line with colloid or colloid with liquid, colloid, this equipment of while has little, the continuous advantage such as online of mixing efficiency height, energy consumption.Can be widely used in industries such as chemical industry, food, pharmacy, metallurgy, building materials, have vast market prospect.
