The centre hole of spray head cone bottom is matched with screw rod of the classifier blade bottom, and is coupling-positioned by means of nut, and between of spray head cone and upper lfnage of spray head is sealed by using fluoroelastomer o-ring seal. The invention grain size is large and its product quality is good, so that it can meet the requirements for agricultural production.
Description
The present invention relates to a kind of prilling spry, be specially adapted to the granulation of high viscosity fusion composite fertilizer.
Background technology of the present invention: existing prilling spry, on structural design, shower nozzle upper flanges and shower nozzle cone adopt bolt to combine as a whole or directly weld and be one, and dividing lodicule is straight plate structure.This prilling spry is mainly used in the granulation of single element fertilizer, and the granulation of inapplicable high viscosity fusion composite fertilizer.
Purpose of design of the present invention: avoid the weak point in the background technology, design a kind of high-viscosity melt rotary spraying granulation nozzle that can be suitable for high viscosity fusion compound fertilizer granulating.
Design of the present invention: molten three elements N; P; K (also can two element N; P or N; K) melt enters in the prilling spry of rotation through static comminutor feed pipe (1); with the centrifugal action of the branch paddle sheet (8) of shower nozzle rotation synchronously and shower nozzle cone (9) under; form certain thickness parabolic liquid layer; spray in the spray orifice that on shower nozzle cone circumference, gathers; be fractured into the drop of constant weight behind the melt jet chance air of ejection; drop is shrunk to spherical particle under the refrigerant effect; refrigerant adopts air or the undissolved liquid of melt material usually, as the mineral wet goods.Its organization plan: main body of the present invention is made up of shower nozzle upper flanges (6) branch paddle sheet (8) and shower nozzle cone (9).Feed pipe (1) is positioned at comminutor hollow spindle (2); shower nozzle upper flanges (6) adopts the half-round clamping ring structure to connect with comminutor hollow spindle (2); promptly half of two identical half-round clamping rings (5) is embedded in the annular groove of comminutor hollow spindle (2), and the part of second half protrusion is blocked shower nozzle supported flange (4) (shower nozzle supported flange (4) concave station and existing half-round clamping ring (5) arranged half match).4～8 connect all-in-one-piece stay-bolt (3) with branch paddle sheet (8) and shower nozzle upper flanges (6) and comminutor hollow spindle (2) are combined as a whole the sealed faying face of special-purpose preheating device when shower nozzle upper flanges (6) outer rim plane is the preheating shower nozzle.Shower nozzle upper flanges (6) end face matches with the table top of comminutor hollow spindle (2).Shower nozzle cone (9) matches with the screw rod that is positioned at branch paddle sheet bottom centre by its bottom centre hole and adopts nut (10) to connect the location, and the sealing of fluororubber O-type sealing ring is adopted in the sealing between shower nozzle cone (9) and shower nozzle upper flanges (6).Have on the shower nozzle cone (9) and the corresponding some spray orifices of discharge rate, spray orifice distributes from cone bottom to top zigzag shape, and the opening diameter of shower nozzle changes between Φ 2.2～Φ 4.8mm.Be provided with 4～8 branch paddle sheets that the identical symmetry of shape is uniform in the shower nozzle cone (9), each blade outer rim is all rolled over the flange that certain angle is arranged.
The present invention compares with background technology, and the one, structural design novelty, uniqueness, simple, stable and reliable working performance, production efficiency height; The 2nd, can adapt to the granulation of high viscosity NPK or high viscosity binary compound fertilizer, its grain sphere diameter of making is big, quality good, can satisfy the demand of agricultural production.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the sectional structure schematic diagram of A-A among Fig. 1.
1 and 2 couple of the present invention does with narration in conjunction with the accompanying drawings.
1. branch paddle sheet (8) has three effects: the one, and can make full-bodied melt material relatively be evenly distributed on shower nozzle cone (9) inwall, form thickness than consistent parabolic shape liquid layer; Two can make the rotating speed of melt material liquid layer and shower nozzle rotate as far as possible synchronously; Three can prevent that the shower nozzle of back taper from causing liquid object and solid delaminating deposition in the melt because of cyclonic action.2. be provided with 4～8 branch paddle sheets that the identical symmetry of shape is uniform in the shower nozzle altogether, each branch paddle sheet outer rim is all rolled over the flange that certain angle is arranged, this flange can be strengthened the mechanical strength of tabular minute paddle sheet, also can play slow compound material simultaneously and directly affact the effect that spray orifice influences jet direction because of centrifugal normal force.The screw rod of branch paddle sheet (8) bottom do not have that screw thread one end has a symmetry with machining process with minute identical straight trough of paddle sheet quantity, combine as a whole with welding manner after branch paddle sheet is bumped into this groove.3. shower nozzle cone (9) connects by a nut (10) with shower nozzle upper flanges (6), and its sealing is finished by the fluororubber O-type sealing ring.Shower nozzle upper flanges (6) and shower nozzle cone (9) taper fit.The sealed faying face of special-purpose preheating device when 4. shower nozzle upper flanges outer rim plane is the preheating shower nozzle.Shower nozzle upper flanges (6) adopts the half-round clamping ring structure with the connection of comminutor hollow spindle (2); two identical half-round clamping rings (5) half be embedded in the annular groove of comminutor hollow spindle (2), the part of second half protrusion blocks shower nozzle supported flange (4), shower nozzle upper flanges (6) and comminutor hollow spindle (2) are combined as a whole with branchs paddle sheet (8) connection all-in-one-piece stay-bolt (3) with 4～8.5. shower nozzle cone (9) has and corresponding several spray orifices of discharge rate, spray orifice distributes from cone bottom to top zigzag shape, the viscosity of the opening diameter visual fusion body material of shower nozzle does not coexist and changes between Φ 2.2～Φ 4.8mm, can be 2.2 or 2.3 or 2.4 or 2.5 or 2.6 or 2.7 or 2.8 or 2.9 or 3.0 or 3.1 or 3.2 or 3.3 or 3.4 or 3.5 or 3.6 or 3.7 or 3.8 or 3.9 or 4.0 or 4.1 or 4.2 or 4.3 or 4.4 or 4.5 or 4.6 or 4.7 or 4.8.
