Description
The present invention relates to a kind of suspension type polytetrafluorethylespecial special bruiser, relate in particular to a kind of serialization and produce suspension type polytetrafluorethylespecial special bruiser.
The suspension method teflon resin is the fabulous material of a kind of performance.It can be ageing-resistant, and the electrical insulating property and the good lubricity of better chemical stability, excellence arranged, and the use temperature scope is wide, by the every profession and trade widespread use.The polymerization of present domestic suspension method teflon resin factory, smash to pieces, dryly all adopt traditional gap method to produce, this technology is backward, labour intensity is big, and influences the visual appearance of product.
Purpose of the present invention is exactly the shortcoming that has now in the suspension method teflon resin production process in order to overcome, and suspension type polytetrafluorethylespecial special bruiser is produced in a kind of serialization that reduces labor intensity, improves the quality of products of design.
The technical scheme that solves the object of the invention is such: a kind of suspension type polytetrafluorethylespecial special bruiser is characterized in that: form by smashing bucket, agitator and spiral separation auger to pieces, agitator and spiral separation auger are by transmission mechanism drive work; The described bucket of smashing to pieces comprises staving and bucket cover: described staving is provided with cooling jacket outward, and correspondence is provided with at least two toothed baffle plates in the staving, a sheathed strainer in the rising pipe of staving bottom; Described bucket cover covers by middle barrel that links to each other and goes up the bucket cover and constitutes, and is located at the top of staving, and described middle barrel of cover is provided with opening for feed and visor; Described agitator is installed in staving at interior the end, and this agitator is three layers, and the upper strata is a propeller blade, and the middle level is a shear-blade, and lower floor is centrifugal slurry; The leading portion of described spiral separation auger is stretched in last bucket cover, and it is horizontal by an angle α who leans forward.
Because the present invention has adopted above structure, make one smash that device can be smashed to pieces to pieces, washing, solid-liquid separation and the multiple unit associations operation of input and output material, and because continuous completely in the production process, pipeline is totally-enclosed, material and external environment are contactless, and the possibility that impurity is carried secretly in the material into is little, and the median size of therefore using the suspension injecting tetrafluoroethylene resin that this device prepares is 0.05 millimeter-0.20 millimeter, tap density is 300g/l-500g/l, and product performance are good.
Be further understanding performance of the present invention, feature, existing as follows in conjunction with a preferred embodiment and description of drawings:
Accompanying drawing one is the overall structure synoptic diagram of preferred embodiment of the present invention;
Accompanying drawing two is structural representations of the axle envelope of the foregoing description.
See also accompanying drawing:
Accompanying drawing 1 is the overall structure synoptic diagram of a preferred embodiment of the present invention, a kind of suspension type polytetrafluorethylespecial special bruiser of the present invention, form by support 1, rack-mount smash to pieces bucket 2, agitator 3 and spiral separation auger 4, agitator and spiral separation auger are by transmission mechanism drive work, and the described bucket 2 of smashing to pieces comprises staving 21 and bucket cover.Described staving 21 is cylindrical, can avoid material to produce the dead angle in smashing process to pieces.Be provided with cooling jacket 211 in staving 21 peripheries.In order to strengthen stirring intensity, enhancement of heat transfer and mass transfer, correspondence is provided with at least two toothed baffle plates 212 in staving 21, and present embodiment is provided with six baffle plates at the equal equal portions of staving inwall, so that the tooth on swiftly flowing particle and the baffle plate plays the impact milling action.Be provided with a water inlet pipe 213 and a rising pipe 214 in staving bottom, material taken out of when preventing water outlet, in the rising pipe 214 of staving bottom, also be provided with a strainer (not shown).Described bucket cover is made of middle bucket cover 22 and last bucket cover 23, and middle bucket cover 22 is tubaeform, and last bucket cover 23 is square, is located at the top of staving 21 after interconnecting.Be provided with opening for feed 221 and visor 222 on middle bucket cover 22, opening for feed 221 links to each other with polymeric kettle by feed-pipe.
At the bottom of passing barrel by it, described agitator 3 is installed in the inside of staving 21.Agitator mainly plays the effect of puddle, mixing and washing.For preventing that a small amount of microparticle from can not produce yellow point or stain when entering the axle envelope, the axle envelope of agitator of the present invention adopts tetrafluoro radiation fins 341 and tetrafluoro seat 342 to constitute, and adopts to be rotatably connected relatively, asks for an interview shown in Figure 2.When smashing to pieces, for the reaction promoter in the washing material, the heat of being convenient to produce when smashing to pieces is taken away, and must add an amount of deionized water.For making stirring, comminuting matter effective, described agitator adopts compound agitator, combine by three layers: the upper strata is a propeller blade 31, and the place has the edge of a knife in sense of rotation, can produce very big cycle rate during the work of this propeller blade and to material by the shearing porphyrization; The middle level is a shear-blade 32, is provided with flanging 321 in the blade outer end, to shear comminuting matter; Lower floor is centrifugal slurry 33, produces certain centrifugal force during high speed rotating, can prevent that the tetrafluoro particle from entering the axle envelope.Like this, when agitator was worked, tetrafluoroethylene was because gravity and buoyancy function in the water, and above the particle that particle diameter is little floated over, the particle that particle diameter is big was positioned at the bottom, was subjected to high speed impact, shearing and pulverized.
Before the dry materials, must and water sepn, take the water yield out of in order to reduce, adopt elongated cylindrical tilting spiral separation auger 4, its leading portion by last bucket cover about hole on two walls be erected in the bucket cover 23, the material of these spiral separation auger 4 promotion water entrainments moves forward helical feed; For being flow backwards, the water in the material advances to smash to pieces bucket, design and installation spiral separation auger 4 of the present invention has the angle α that leans forward with horizontal plane, this angle [alpha] is advisable with 10 °-30 °, and it is 20 ° that present embodiment is selected forward leaning angle, reaches the purpose of thing, water sepn and conveying.Spiral separation auger 4 is selected the varying pitch formula for use, and along with material moves forward, pitch increases gradually, makes material keep loose, prevents that the material caking from entering feeder, blocking pipe.
Transmission mechanism of the present invention comprises electric motor 5, variator 6 and travelling belt.Electric motor 5 is connected with stir shaft by one group of travelling belt, and stir shaft extend in the staving from smashing the staving bottom to pieces, and this structure has and turns round steady, good seal performance, long service life and be convenient to take over the characteristics of installation.Electric motor 5 also drives another group travelling belt by variator 6 and is connected with the transmission shaft of spiral separation auger 4, drives 4 work of spiral separation auger.
Suspension type polytetrafluorethylespecial special bruiser of the present invention, can under the totally enclosed condition of pipeline, serialization produce the tetrafluoroethylene product, thereby operator have been cut down, alleviated labour intensity, improved quality product, month ratio of first-grade products can improve 6%, and has reduced tankage, for country has created good economic benefit and social benefit.
