Abstract

The utility model relates to a granulator used for mechanically extruding powdery fertilizer into granular fertilizer, which is particularly suitable for the granulation of powdery ammonium chloride. The granulator comprises a roller, a cutter arranged on the body of the granulator and a granulation die which is driven by a hollow shaft perpendicular to the shaft line of the roller and provided with die holes. The granulator can be used for continuously pressing powdery ammonium chloride, forming degree is high, die is not difficult to release, die plates can be processed conveniently, and the die plates can not clot in the process of transportation. The granulator has convenience for mechanically fertilizing, and the granulator is an ideal device for the granulation of powdery ammonium chloride.

Description

Granulator for ammonium-chloride monomer

The utility model is a kind of powdered fertilizer to be processed as the granulating equipment of particulate state fertilizer by mechanical presses, is particularly suitable for the granulation of powdery ammonium chloride.

The design of " chemical machinery " 1985 the 5th phase double roller compaction granulators of publishing according to chemical machinery institute of Ministry of Chemical Industry "; its purpose of design; be mechanical presses effect by pair roller, powdered fertilizer is made the granulated fertilizer of certain granules shape.

Double roller compaction granulator sees that Fig. 1 main composition is a pair of horizontal positioned; the roll that diameter is identical; two roll shop buildings have certain interval; both do opposite spin with same rotational speed; many shapes have been arranged on the roller surface regularly; the hole, spheroid cave that size is identical; pulverulent material adds down continuously equably from two rolls top; continuous rotation along with roll; reduce gradually in the space that material occupies; and be compressed gradually; and reach the forming pressure maximum value, and pressure reduces gradually subsequently, and the agglomerate of pressing increases because of the elastic recovery size; the applying of agglomerate and cave hole wall is damaged, and adds the weight of itself and successfully comes off.

The main deficiency of rolling the formula tablets press is: the hole, cave of roller surface is the oblate spheroid type, and the cave hole number is many, requirement on machining accuracy height, thereby processing difficulties, and expense is big; The wearing and tearing of roll width direction are irregular, cause two roll seams irregular, are difficult to repair, and make it to scrap too early; Moreover because the gap of roll shop building and the distance between the hole, cave, when rolling small-particle, the type ball joins together.Chinese patent application number adopts multiple roller granulation for the tablets press of the suitable bicarbonate of ammonia that 85202155U proposed; has the pellet throwing mechanism; because push rod can not head into the darker position of nib; so short grained ejecting still had certain difficulty, and output is also low.

The purpose of this utility model is to develop a kind of ratio of briquetting height, and the demoulding is easy, and mould is easy to process, economical, easy to be changed, and is particularly suitable for the granulating equipment of powdery ammonium chloride granulation.

The purpose that the utility model proposes solves by following technical proposal, granulating equipment primary member of the present utility model comprises the running roller that is installed on the rolling axle, and its maximum characteristics are also to comprise the pellet-forming mould ring with nib that drives with the orthogonal tubular shaft of this rolling axle axis and are fixed on cutting knife on the body; With pellet-forming mould ring the running roller in one gap is arranged, produce friction and drive running roller and do rotation because powder is got involved the gap; In order to increase friction, the groove parallel with the running roller medullary ray arranged at the running roller outside surface.For producing the needs of different densities and the granular ammonium chloride of particle length, the gap of pellet-forming mould ring and liquid wheel can utilize packing ring adjustment, and the distance of cutting knife and pellet-forming mould ring also can be adjusted; In order to prevent grain breakage, external form is that the batch mixing pan and the body inwall of cone can be lined with buffer substrate tablet simultaneously; Nib on the pellet-forming mould ring can have been made upper and lower two-part hole, and the bottom is a circular hole, and top is a taper material guide hole.The plane that the maximum radius of gyration of this nib constitutes is positioned at the running roller side; The inner cover of granulating equipment is fixed on the pellet-forming mould ring.

The utility model has solved the difficult problem of powdery ammonium chloride mechanical pelleting, can suppress granular ammonium chloride continuously, and there is not the demoulding difficulty in the ratio of briquetting height, and template is easy to process, economical.Particle ammonium chloride is used as when topdressing, and sticking leaf can not occur and burn the seedling phenomenon, can not lump in transportation, brings great convenience to the user, has saved wrapping material, is convenient to the mechanized application operation.

Drawing is described as follows:

Fig. 1 is a double roller compaction granulator sketch in the prior art.

Fig. 2 is the synoptic diagram of ammonium chloride granulating equipment.

Fig. 3 is the schematic top plan view of ammonium chloride granulating equipment.

Powder is evenly distributed on the pellet-forming mould ring 7 of the garden shape that is covered with nib 3 through outer cover 1 and inner cover 2 feed hole, inner cover 2 adopts screw attachment with pellet-forming mould ring 7, hold-down nut is fixed on running roller seat 4 on the central shaft 5, by bearing running roller 3 and running roller seat 4 is linked up; When making continuous operation with the pellet-forming mould ring 7 that axle connects by key 16 with 6 drives of bearing 15 bonded tubular shafts, inner cover 2 is with pellet-forming mould ring 7 rotations, powder is nipped by running roller 3, because the rubbing effect of powder makes running roller 3 do rotation.Be placed with packing ring 14 between tubular shaft step and the pellet-forming mould ring to adjust the gap of pellet-forming mould ring and running roller; Powder on the pellet-forming mould ring just constantly is pressed into nib 8 like this, the strip-shaped materials that is extruded from the nib below is cut into desired length by the cutting knife 9 that is contained on the body 12 that can adjust with pellet-forming mould ring 7 spacings, granule materials is through posting soft plastic 11, push down by packing ring 14 and pellet-forming mould ring 7, and with the batch mixing pan 10 of pellet-forming mould ring 7 rotation to discharge port 13, thereby finished the granulation of powdery ammonium chloride.
