Description
The invention belongs to comminutor and make the field.
Background technology of the present invention: existing centrifugal comminutor can be divided into two classes, i.e. central feeding and side charging two classes.(comminutor main shaft 23) passes through central feeding (Fig. 3) at the transmission mechanism center owing to fused solution, and high temperature often causes the generation of mechanical breakdown to the influence of driving member such as gear, bearing, oil sealing etc., and this kind equipment not too uses at present.Side charging (Fig. 4) is owing to changed feeding structure, and the volume of equipment, weight and maintenance have all had improvement, and the big-and-middle chemical fertilizer factory of present domestic introduction and the major part of homemade little chemical fertilizer all adopt the comminutor of this type.The opening port that an annular is arranged in the middle of revolving part prilling spry and the static element charging box, shower nozzle its internal liquid when rotated is to be hyperbolic wire (Fig. 5), when normal condition, liquid constantly sprays simultaneously through centrifugal action constantly to be mended again in the feed pipe, the liquid layer thickness of shower nozzle inside is constant, but it is for various reasons, blocked as the spray orifice part.Inlet amount increases suddenly.Rotating speed descends suddenly degradation often to cause solution layer thickness to thicken so that overflow from annular opening, and the solution that overflows can not become to drip cooling, accident (this type of accident is common in the less homemade little urea plant of tower diameter) at the bottom of Here it is the sticking tower that the chemical plant often says.In order to reduce this type of accident, often adopt increasing the shower nozzle eyelet is the way of perforated area, just equals to have reduced liquid layer thickness and increased perforated area, unfavorable again to the granulation effect like this, shows the less than normal even dust increase of particle diameter etc.
Purpose of design of the present invention: avoid the weak point in the existing background technology, design a kind of shortcoming that promptly can avoid central feeding in the background technology, can solve the bottom-mounted rotary-jointing granulating machine of the problem of side charging overflow again.
Design of the present invention: the principle of centrifugal granulating is: temperature is delivered to the high granulation tower of tens of rice at the chemical fertilizer liquid of 140 ℃ (fusing ureas) or 170 ℃ (fusion ammonium nitrates) through Melting pump, enter the prilling spry of unidirectional rotation through feed pipe, fused solution under the effect of prilling spry rotating centrifugal several apertures of blowing nose cone face circumference with the ejection of the speed of 2～8 meter per seconds, the resistance fracture that the thread of ejection is met air is divided into drop, drop solidifies in the freely falling body process, the spherical particles of generation with cooled off gradually when air contacts.In order to realize this purpose; this comminutor employing central feeding combines with the side charging; be that fused materials still enters swivel joint by the transmission mechanism outside through feed pipe; central duct through swivel joint enters prilling spry again; so promptly avoid the shortcoming of central feeding, solved the problem of side charging overflow again.On structural design, changed original charging box (24) into swivel joint (6) (Fig. 1) in existing side charging comminutor bottom, fused solution enters swivel joint (6) through feed pipe (3), metal hose (4), there is a spline hole swivel joint (6) upper surface, with the spline pin loose fit on the comminutor end face flange, the spline pin works to prevent that the swivel joint housing from rotating with core; The effect of metal hose (4) is that the error of processing and manufacturing process and the thermal expansion of metal tube are compensated.Its feed process: the feed process of bottom-mounted rotary-jointing granulating machine, the side charging combines with central feeding.The charging assembly is the side charging with being communicated with of swivel joint, and swivel joint is a central feeding with being communicated with of prilling spry.Its organization plan: bottom-mounted rotary-jointing granulating machine; it comprises comminutor motor (1), transmission mechanism (2), prilling spry (7); be swivel joint (6) between transmission mechanism (2) and the prilling spry (7), the discharging opening of charging assembly is communicated with the charging hole of swivel joint sidepiece.There is a spline hole upper surface of swivel joint (6) and is connected by the end face of spline pin (6) with transmission mechanism (2).Spline hole and spline pin are loose fit.The charging assembly is communicated with formation by feed pipe (3) and flexible pipe (4).The sidepiece of swivel joint (6) has charging hole, change core (8) middle part has several waist-shaped holes and communicates with the central well that changes core.
The present invention compares with background technology, the one, the charging assembly by the charging of swivel joint sidepiece charging hole after, enter the structural design of prilling spry again through the central duct of swivel joint, not only avoided the shortcoming of central feeding in the background technology, and solved the problem of side charging overflow in the background technology; The 2nd, granulation is effective, by about present granulation diameter 0.8mm about rising 2mm, makes the quality of product produce qualitative leap; The 3rd, structural design uniqueness, simple, its stable and reliable working performance.
