Abstract

A cyclone granulator includes a barrel, a cyclone column and a diverter arranged in the barrel, a feeding device, an atomizing device and a discharge bucket. The rocket-shaped cyclone column is arranged at the bottom of the barrel, the inverted conical diverter is arranged on the top of the barrel, the bottom of the barrel is provided with an air inlet and the top with an air outlet, and the designed air volume into and out of the barrel is the same. The feeding device consists of a feeding barrel and a pneumatic discharge tube, the nozzle of the atomizing device is arranged between the inverted conical diverter and the rocket-shaped cyclone column, and the discharge bucket is arranged below the rocket-shaped cyclone column. The utility model can complete the whole process of powder granulation by using only one equipment. Compared with the prior granulator, the utility model has the advantages of simple equipment, advanced technology, small occupied area, high production efficiency, low energy consumption, ball diameter adjustment through the air volume and wide application scope. The utility model can be used in industries, which need granulation, such as sugar tablets, medicine tablets, feed grain, concrete additives and chemical fertilizers.

Description

The cyclone comminutor

(1) technical field

The utility model belongs to Granulation Equipments, is specifically related to a kind of cyclone comminutor.

(2) background technology

At present, the Granulation Equipments that is used for chemical industry and pharmaceutical industry is bulky, complex process, need process and material, stirring, compressing tablet, slitting, pelletizing, roll grain, wrap up in operation streamline productions such as skin, oven dry, quality is wayward, the energy consumption height, the equipment manufacturing cost height uses the integrated cost height.

(3) summary of the invention

Technical problem to be solved in the utility model is that Granulation Equipments is bulky, complex process, and quality is wayward, now provides a kind of volume little, and cost is low, and production technology is simple, constant product quality, the cyclone comminutor that purposes is wide.

Technical solution of the present utility model is; The cyclone comminutor comprises staving, is arranged on whirlwind post and current divider, drawing-in device, sprayer unit and discharge bucket in the staving.Rocket shape whirlwind post is arranged on the staving bottom, and the back taper current divider is arranged on the staving top, and staving bottom circumference is provided with air inlet, and the staving top circumference is provided with exhaust outlet, and the air quantity design of turnover staving equates; Drawing-in device is arranged on the staving upper outside, is made up of feeding bucket, pneumatic discharge tube, and the discharging opening of feeding bucket is connected with pneumatic discharge tube; The water tank of sprayer unit is arranged on the staving outside, and its shower nozzle is between back taper current divider and rocket shape whirlwind post, and discharge bucket is positioned at rocket shape whirlwind post below.

Be vertically installed with screw feeder in the above-mentioned feeding bucket.

The utility model is provided with air inlet in the staving bottom, at the staving top exhaust outlet is set, because the air quantity design of turnover staving is equal, makes and forms stable dynamic swirling eddy in the staving.Be provided with rocket shape whirlwind post at the staving center, air-flow forms high wind district and time high wind district successively at rocket shape whirlwind columnar region; The top is owing to the effect of back taper current divider, and air-flow forms the eddy current center in this zone, forms the high wind district once more; Between staving top back taper current divider and rocket shape whirlwind post, do not stop that air-flow slows down at this regional rotating speed, form the apoplexy district.

During work, granular material is poured in the feeding bucket, advanced through screw feeder, granular material quantitatively falls into the wind-force discharge tube, and under the effect of air blast, granular material is vaporific and sprays in the bucket, under the effect of apoplexy district eddy airstream, the granular material that sprays into is unsettled rotation shape.At this moment, quantitative water smoke is evenly sprayed to the granular material of rotation by sprayer unit, after granular material gets wet, form particulate, particulate is changed tracks in rotary course, under the acting in conjunction of centrifugal force and gravity, rotation is from top to bottom rolled descending, particulate forms spheroid, and weight and volume increases gradually; Spheroid passes through time high wind district and high wind district successively, along with the rotation rolling speed strengthens, spheroid centrifugal force also strengthens with the rolling compaction power that the bucket wall forms, and ball density is increased, intensity improves, and meets the requirements of the spheroid product and falls into discharge bucket along rocket shape whirlwind post lower taper slope.In the granular material rotary course, the part particulate is rotated air-flow and carries secretly to the staving top, under the effect of the high wind district eddy airstream that top back taper current divider forms, the particulate rotation is sunk and is continued to be advanced into granulation process under the rotation in company with the granular material that has just sprayed into.

The utility model only just can be finished the overall process of granular material granulation with an equipment; its equipment is simple, technology advanced person, low cost of manufacture; to compare floor space little with existing comminutor; the production efficiency height, it is low to consume energy, and workshop does not have dust emission; noiselessness; the sphere diameter of producing can be regulated by the air quantity of adjusting the turnover staving, and is applied widely, and can be used for sugar grain, medicine grain, feed grain, concrete additive, chemical fertilizer etc. needs the industry of granulation to use.

(4) description of drawings

Further describe the utility model below in conjunction with accompanying drawing:

Fig. 1 is a cyclone comminutor structural representation;

Fig. 2 is a cyclone comminutor drawing-in device structural representation.

(5) specific embodiment

As shown in Figure 1, the cyclone comminutor is made up of staving 6, drawing-in device 4, sprayer unit 9, discharge bucket 12 and the whirlwind post 7 and the current divider 3 that are arranged in the staving.Staving is installed on the frame 11, is evenly distributed in three air inlets 8 in the staving bottom, and the staving top circumference is evenly equipped with three exhaust outlets 2, and the air quantity design of turnover staving equates.

Whirlwind post 7 is a rocket shape, is fixed on the staving bottom, and the current divider 3 of back taper is fixed on the staving top.Drawing-in device 4 is arranged on the staving upper outside, be vertically installed with screw feeder 14 in the feeding bucket 13, the discharging opening of feeding bucket is connected with pneumatic discharge tube 5, discharge tube 5 is communicated with staving 6, blower fan 17 is installed in the discharge tube end, screw feeder 14 is by motor 16, belt 15 transmissions, as shown in Figure 2.

The water tank of sprayer unit 9 is arranged on the staving outside, and its shower nozzle 10 is arranged between back taper current divider 3 and the rocket shape whirlwind post 7, and discharge bucket 12 is positioned at rocket shape whirlwind post 7 belows.

For avoiding a spot of dust to be taken out of from exhaust outlet 2 by exhaust blower, the exhaust duct outer end that is connected with exhaust outlet is provided with device for recovering powder 1, and the minitype particle of being taken out of by air-flow can reclaim by retracting device like this.
