Description

Take granule device that wind drenched

Technical Field

The utility model belongs to the technical field of pharmacy, and particularly relates to a granular granulation device with air showering.

Background

The existing commonly used granule granulating equipment in the pharmaceutical industry comprises swing granulation and extrusion granulation, the swing granulation usually generates a large amount of fine powder, the forming rate is low, the fine powder is easy to enter a shaft to be mixed with engine oil, and the fine powder falls out in the granulating process to pollute granules; the extrusion granulation is divided into horizontal screw extrusion granulation and vertical impeller extrusion granulation, and the horizontal screw extrusion granulation is easy to accumulate materials, generate heat, damage a screen and choke; the disassembly and the cleaning are difficult, and the working time is usually not long; the vertical impeller extrusion granulation is relatively practical, and the vertical structure is adopted, so that the screen can be automatically lifted, the cleaning is easy, and the choking phenomenon is avoided; the machine is provided with a feed hopper, an extrusion blade, an extrusion net, a receiving hopper, a motor, a water cooling system and the like; the wet medicine is fed from a feed hopper and extruded from an extrusion net by an extrusion blade to form a long cylindrical strip. After extrusion, the particles can lose water, become brittle and break, fall into a discharging hopper, are dried by a fluidized dryer and are granulated by a granulator to form short cylindrical particles; for example, the disclosed 'granule machine', patent No. CN201520178076.3, some are also provided with a water cooling system, which can realize continuous and long-time uninterrupted production; however, the method still has the disadvantages that the cold water cavity is cooled in the lower sealing disc of the extrusion cavity, but the impeller rotating at high speed rubs the material and the wall of the extrusion cavity to generate heat, so that the temperature of the just extruded cylindrical strip-shaped medicine still reaches more than 50 ℃, the outer ring of the screen is surrounded by the humid and hot air, the humid and hot air is condensed into water drops when meeting the outer surface of the lower sealing disc provided with the cold water cavity, the medicine cannot be rapidly dehydrated, becomes brittle and breaks after being extruded out of the screen, falls on the outer surface of the lower sealing disc, the water drops on the lower sealing disc become wet, soft and sticky, particularly, the traditional Chinese medicine granules have strong hygroscopicity, are more accumulated and more wet, form lumps and are difficult to dry, and have poor granularity after drying, even though some granules are generated by grading, compared with non-agglomerated scattered granules, the color of the granules is heavier, the integral granules have inconsistent color and have dark and light depth, and the appearance quality of the granules is influenced.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model aims to provide a granular granulating device with air showering.

The utility model adopts the following technical scheme for achieving the purpose:

a granule granulating device with air shower is provided with a feed hopper; the feed hopper is communicated with the receiving hopper through the extrusion net; a lower sealing disc is arranged between the extrusion net and the receiving hopper; an annular pipe is arranged between the feed hopper and the extrusion net; the annular pipe is fixed on a binding ring at the lower end of the feed hopper through a bayonet; the pipe orifice of the annular pipe is connected with a compressed air pipeline through a plastic pipe; the lower wall surface of the annular pipe is provided with a plurality of air outlet holes; the air outlet is needle eye shaped; a plurality of air outlet holes are communicated with the annular pipe; a plurality of the air outlets, the annular pipes and the compressed air pipeline jointly form a wind showering device which can downwards disperse the humid and hot air around the extrusion net and avoid the water vapor from condensing into water drops and adhering the medicine on the surface of the lower sealing disc.

The annular tube is fixed on the binding ring through a buckle.

And an air valve for adjusting the size of the compressed air is arranged on the compressed air pipeline.

According to the granulating device with the air showers, provided by the utility model, by adopting the technical scheme, the compressed air overflows from the air outlet hole, and the damp and hot air around the extrusion net is downwards dispersed, so that the water vapor is prevented from being condensed into water drops on the surface of the lower sealing disc to adhere to the medicine; the extruded long cylindrical medicine is dehydrated quickly, becomes semi-dry, brittle and broken, falls downwards into a receiving hopper, is dried by a boiling dryer, and is granulated by a granulating machine into cylindrical granules with consistent color and luster and uniform size; the forming rate of the particles and the appearance quality of the particles are improved.

Drawings

FIG. 1 is a schematic view of the present invention.

FIG. 2 is a schematic view showing the structure of the ring tube of the present invention.

In the figure: 1. the device comprises a feeding hopper, 2. a binding ring, 3. a buckle, 4. an annular pipe, 4-1. an air hole, 4-2. a pipe orifice, 5. an extrusion net, 6. a lower sealing disc, 7. a receiving hopper, 8. a plastic pipe, 9. an air valve and 10. a compressed air pipeline.

Detailed Description

The utility model will be further described with reference to the accompanying drawings, without limiting the scope of the utility model to the following:

as shown in figures 1 and 2, the granule granulating device with the air shower is characterized in that an annular pipe 4 is arranged below a binding ring 2 on an extrusion net 5, the annular pipe is fixed on the binding ring 2 through two buckles 3, a pipe opening 4-2 on the annular pipe is connected with a plastic pipe 8, the other end of the plastic pipe 8 is connected with a compressed air pipeline 10, and the size of air is adjusted through an air valve 9 on the compressed air pipeline. A plurality of pinhole-like air holes 4-1 are arranged below the annular tube, compressed air overflows from the air holes 4-1 and downwards disperses damp and hot air around the extrusion net 5, so that water vapor is prevented from being condensed into water drops on the surface of the lower sealing disc 6 to adhere to the medicine. The medicine is extruded from the extrusion net, becomes cylindrical, quickly loses water, becomes semi-dry, brittle and broken, directly falls into the receiving hopper 7, is subjected to boiling drying, and is granulated by a granulator to prepare short cylindrical granules with consistent color and uniform size.

The technical scheme has simple structure, convenient operation and obvious effect; the moist and hot air around the extrusion net is quickly dispersed, so that the extruded medicine strips are quickly dehydrated, become crisp and are not adhered; meanwhile, the cooling effect is achieved, and the continuous production time is prolonged.
