Description
Technical field
The utility model embodiment is related to centrifugal spray drying technical field, specifically a kind of centrifugal spray drying device.
Background technology
Currently, drying machine with centrifugal spray is that certain liquid materials are dried using centrifugal type atomizer, it is current
One of most popular drying machine in industrial production.Spray drying is most widely used in liquid process forming and dry industry
Technique.It is best suited for generating powdery, granular product in solution, lotion, suspension and pumpability liquid/paste raw material.Therefore
When particle size distribution, residual moisture content, bulk density and grain shape meet accurate standard, spray drying is together
Very ideal technique.
The defect that centrifugal spray dryer in the prior art has is that general set-up mode is to sweep hot wind from gas
It is passed through at the top of pipe, since hot-air density is smaller, it is therefore desirable to which high-power air blast could advertise hot wind, and hot wind
From top to bottom injection keeps drying tower internal upper part temperature higher, and bad influence is generated on drying effect.
Therefore, there is an urgent need for one kind can reach the preferable centrifugal spray drying device of drying effect by specific structure.
Utility model content
The utility model embodiment provides a kind of centrifugal spray that can reach preferable drying effect by specific structure
Drying device is to solve the above problems.
In order to solve the above-mentioned technical problem, the utility model embodiment discloses following technical solution：
A kind of centrifugal spray drying device, including drying tower, the dry column overhead are provided with spraying device, the drying
The gas being provided in tower along the dry inner wall of tower rotation sweeps pipe, and the gas is swept pipe and driven by motor, the dry inner wall of tower
It is provided with ring-shaped guide rail, the gas is swept tube top end and slided along the ring-shaped guide rail, and the gas sweeps tube bottom end and is connected with rotation
Feeder, the rotation feeder drive shaft that includes shell and connect with the motor drive are arranged on the shell
There are hot wind air inlet pipe, the shell to sweep pipe with the gas and connect by the first sealing bearing, the gas, which is swept, is provided with connection in pipe
Plate is provided with several through-holes, the connecting plate and the driving axis connection on the connecting plate.
As a kind of optimal technical scheme of the utility model embodiment, the one end of the drive shaft far from the connecting plate
It is provided with cone bearing.
As a kind of optimal technical scheme of the utility model embodiment, the drive shaft be located at the hot wind air inlet pipe and
Be provided with shaft sealer between the cone bearing, the shaft sealer include be arranged in the drive shaft it is second close
Envelope bearing and the bearing block being arranged in the shell.
As a kind of optimal technical scheme of the utility model embodiment, the gas sweeps pipe close to the drying tower axle center
If side is evenly distributed with dry gas cleaning bottom of hole.
As a kind of optimal technical scheme of the utility model embodiment, the dry tower side wall is provided with discharge pipe.
As a kind of optimal technical scheme of the utility model embodiment, the drive shaft lower end by speed reducer with
The motor drive connection.
It is by above technical scheme as it can be seen that beneficial possessed by the centrifugal spray drying device that the utility model embodiment provides
Effect is：Pipe is swept by the gas of above structure and rotates feeder, and the lower section entrance that hot wind is swept pipe by gas, hot gas may be implemented
Density is smaller therefore is easier to make for moving, and material bottom is first heated in drying tower, and drying effect is more balanced, improves
Drying effect.
It disclosure satisfy that gas sweeps the effect of pipe rotation and gas supply by the rotation feeder of above structure, structure is relatively simple
And good seal performance, it can be adapted for the environment of high temperature in drying tower.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Description needed in attached drawing be briefly described, it should be apparent that, for those of ordinary skills,
Under the premise of not making the creative labor, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram for the centrifugal spray drying device that the utility model embodiment provides；
Fig. 2 is the structural schematic diagram that feeder is rotated in the utility model embodiment.
Specific implementation mode
In order to make those skilled in the art more fully understand the technical solution in the utility model, below in conjunction with this reality
With the attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on the utility model
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example should all belong to the range of the utility model protection.
It please refers to shown in attached Fig. 1 and 2, Fig. 1 is the structure for the centrifugal spray drying device that the utility model embodiment provides
Schematic diagram, Fig. 2 are the structural schematic diagram that feeder is rotated in the utility model embodiment, and spray is centrifuged disclosed in the present embodiment
Mist drying device, including side wall are provided with the drying tower 1 of discharge pipe 11, and 1 tower top of the drying tower is provided with spraying device 2,
It is provided with the gas rotated along 1 inner wall of the drying tower in the drying tower 1 and sweeps pipe 3, the gas is swept pipe 3 and driven by motor 4, institute
It states 1 inner wall of drying tower and is provided with ring-shaped guide rail 5, the gas is swept 3 top of pipe and slided along the ring-shaped guide rail 5, and the gas is swept
