This utility model relates to pharmaceutical production apparatus field, is specifically related to a kind of drying equipment.

Background technology

During pharmaceutical production, generally requiring and be dried some bead dosage form, traditional is dry Dry mode is usually and uses dry gas to be dried, but traditional pneumatic conveying dryer needs to set Putting the longest drying tube and can be only achieved final drying purpose, for this problem, design is a kind of novel Gas drying apparatus be the most necessary.

Utility model content

For problem above, this utility model provides a kind of drying equipment, and material is at this utility model Inside rotate, increase material stroke, i.e. increase the time of staying of material, therefore, be dried Pipe can be oversize, solves the long problem of drying tube.

To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of drying equipment, Including frame and drying device, described drying device includes being dried cylinder, air inlet pipe, feed pipe and going out Trachea, described dry cylinder is fixedly mounted in frame, is provided with shaft in described cylinder, described in stir Mixing axle and be provided with stirring vane, described stirring vane uses sped structure, the end of described dry cylinder End connects air inlet pipe one end, and the top of described dry cylinder connects escape pipe, and described feed pipe is positioned at dry The side of dry cylinder, described feed pipe connects has feed hopper, described feed hopper to be arranged in frame, institute Being provided with spiral material extruder in stating feed pipe described in feed hopper, the other end of described air inlet pipe connects air blast Machine, described aerator is provided with heater.

Further, being provided with drainage screen in described drying body, drainage screen is active multi-layer structure, and Can be replaced according to preparation demand or increase and decrease.

Further, the mouth of pipe of described escape pipe is provided with protective cover.

The beneficial effects of the utility model:

Unit volume evaporability of the present utility model is high, and material can be made to be dried rapidly, reach efficiently, Quickly, the effect of the big production of skinny device；Material rotates in equipment, increases material stroke, I.e. increasing the time of staying of material, therefore, drying tube can be oversize, solves drying tube long Problem；Equipment center region is pneumatic conveying drying, makes area under control, rotary flashing drying center be strengthened, carries High rate of drying and dry yield；Owing to eddy flow exists with ascending air simultaneously, increase between air-flow, Air-flow and the mutual turbulent flow of storeroom, form eddy current fluidized drying, improve heat and mass transfer coefficient, accelerates The rate of drying of material, advantageously reduces the moisture content of product.

Being numbered in figure: 1-frame, 2-drying device, 3-is dried cylinder, 4-air inlet pipe, 5-escape pipe, 6-shaft, 7-stirring vane, 8-feed pipe, 9-feed hopper, 10-spiral material extruder, 11-aerator, 12-heater, 13-drainage screen, 14-protective cover.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.

As illustrated in fig. 1 and 2, a kind of drying equipment, including frame 1 and drying device 2, described dry Device 2 includes being dried cylinder 3, air inlet pipe 4, feed pipe 8 and escape pipe 5, described dry cylinder 3 It is fixedly mounted in frame 1, is provided with shaft 6 in described dry cylinder 3, described shaft 6 sets Having stirring vane 7, the bottom of described dry cylinder 3 connects air inlet pipe 4 one end, described dry cylinder 3 Top connect escape pipe 5, described feed pipe 8 is positioned at the side of dry cylinder 3, described feed pipe 8 Connecting has feed hopper 9, described feed hopper 9 to be arranged in frame 1, feed pipe described in described feed hopper 9 Being provided with spiral material extruder 10 in 8, the other end of described air inlet pipe 4 connects aerator 11, described drum Blower fan 11 is provided with heater 12.

On above-described embodiment preferably, described stirring vane 7 uses sped structure, makes stirring more Uniformly.

, being provided with drainage screen 13 in described dry cylinder 3, drainage screen 13 is on above-described embodiment preferably Active multi-layer structure, it is possible to be replaced according to preparation demand or increase and decrease, compares medicine filtering some The impurity that granule is little.

On above-described embodiment preferably, the mouth of pipe of described escape pipe 5 is provided with protective cover 14, prevents waste gas Fly around.

Concrete this utility model provides the gas being dried by aerator and heater, be dried gas by Air inlet pipe enters and is dried in cylinder 3, and material is entered by feed pipe 8 and is dried cylinder 3, is then dried gas Material is dried by body, and now, stirring vane 7 is stirred, and the material made is heated in cylinder The most elongated with heated time, escape pipe 5 is to discharge dried waste gas.

Based on above-mentioned, this utility model has advantages in that unit volume of the present utility model is evaporated Ability is high, material can be made to be dried rapidly, reach efficient, quick, the effect of the big production of skinny device；Thing Material rotates in equipment, increases material stroke, i.e. increases the time of staying of material, because of This, drying tube can be oversize, solves the long problem of drying tube；Equipment center region is that air-flow is done Dry, make area under control, rotary flashing drying center be strengthened, improve rate of drying and dry yield；By Exist with ascending air in eddy flow simultaneously, increase between air-flow, air-flow and the mutual turbulent flow of storeroom, shape Become eddy current fluidized drying, improve heat and mass transfer coefficient, accelerate the rate of drying of material, be conducive to fall The moisture content of low production.

The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle Deng, within should be included in protection domain of the present utility model.
