Abstract
The present invention is the prilling process of polyacrylamide, be characterized in the screw rod squeeze side to discharging, on the urceolus of rotation, open many apertures, being cut into micelle by a cutting knife at this jelly of extruding is dropping on the guipure that is turning round forward, send into far-infrared dryer and carry out drying, replace traditional prilling process with this, have that energy consumption is low, micelle does not stick, an advantage of efficient height, fast drying.
The present invention shows in trial production: granulation is smooth.
Description
Invention field the invention belongs to the polymer-type flocculant and makes the field, is the prilling process of acryl amide gel, and granulator, adopts screw rod extruding drum side direction discharging comminutor.
The concentration acryl amide gel, and granulator must be through granulation before dry in the technical background.Because the adhesion of this jelly is very strong, granulation is very difficult.The general screw extruder that adopts the meat grinder formula of past is transformed a little, increases by an outer cut and is cut into granular.Carry out heated-air drying with garden drum drier or roller drier again.These methods are difficult to produce the jelly particle of simple grain, easily heavily stick into bulk, the dissolution time when having influenced rate of drying and use.
Summary of the invention: the present invention adopts the screw rod comminution granulation, be very different but extrude with aforesaid screw rod, usefulness be screw rod extruding drum rotation side direction discharging comminutor.It is not axial discharging, but the side direction discharging.So just greatly perforate and distribution range have been enlarged, as shown in the figure.
The extruding drum comminutor is installed on the support (13); the screw rod of screw feeder (4), granulation screw (7) and cylinder (6) are driven by buncher (1) (having decelerator) respectively, and with sprocket wheel (3); (9), (12) and chain (10) transmission.Screw shaft and drum rotation axis all are bearing in roller bearings (2), on (5) and (11).Feeding spiro rod and granulation screw form with stainless steel or carbon steel car system or forging, but as use carbon steel, then must chromium plating.The cylinder material can be a metal, also can be duroplasts, also can the two dual-purpose.
On the side of cylinder, from front to back, be drilled with the hole of φ 2-φ 14, all Kong Jun are by necessarily regularly arranged, and are best with spirality.
The acryl amide gel, and granulator that is cut into strip is put into the hopper of screw feeder, deliver to the granulation section through feeding spiro rod, because the extruding of screw rod, jelly is extruded from the hole of cylinder side, cylinder rotates simultaneously, and its direction is opposite with the screw rod direction, helps extruding of micelle, the blade of the cutting knife that the adhesive tape of extruding is fixed (8) is cut into particle, directly is assigned on the guipure of operation forward.Guipure is driven by buncher and decelerator, delivers to the far-infrared ray drying device and carries out drying.
The present invention shows in trial production: granulation is smooth.
Such granulation, blanking and method of shipment can not make the jelly that is cut into grain stick together once again, help dry uniformity.
The width of guipure and drum length must be worked good.For adapting to the drying device of different abilities and speed, fabric thickness can be regulated.Utilize granulation screw, the thickness of cloth is regulated in the variation of cylinder and feeding speed, the uniformity and adaptability to the different hardness micelle.
