Technical Field

The invention relates to the field of atomization device structures, in particular to an atomization device for a dryer.

Background

The spray drying technique is a method for directly preparing microparticles from a solution or slurry by means of rapid evaporation, and comprises two processes of spraying and drying. The slurry is first sprayed into mist-like micro-droplets, then the water is evaporated and carried away by hot air, and then the solid matters in the droplets are gathered into dry particles. The powder particles formed by atomization and drying are approximately spherical with a plurality of fine particles agglomerated, the whole process is carried out in a closed system, and no dust or impurity pollution is caused.

The atomization device is always the core equipment of spray drying, the atomization effect is good or bad, and the uniformity and the quality of the product are directly influenced. When the weight of the mist liquid drops is increased, the settling speed is accelerated, so that the retention time of the mist liquid drops in the tower body is reduced, and finally the drying effect of the material is poor. And the material causes easily splashing at the atomizing disk high-speed rotation atomizing in-process, influences the atomizing effect.

Disclosure of Invention

The invention provides an atomizing device for a dryer, which solves the problems of poor drying effect caused by low atomizing uniformity of the existing atomizing device.

In order to solve the technical problems, the technical scheme of the invention is as follows:

the utility model provides an atomizing device for desiccator, includes the mounting base, install the back taper casing on the mounting base, fixed mounting has the motor in the casing, atomizing disk is installed to the power take off end of motor, the back taper hole has been seted up around the motor on the casing bottom surface, the casing overcoat is equipped with air ducting, air ducting's air-out end flushes with the bottom surface of casing.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, an atomizing device for desiccator, including mounting base 5, mounting base 5 is last to install back taper casing 7, fixed mounting has motor 1 in casing 7, atomizing disk 2 is installed to motor 1's power take off end, and atomizing disk 2 rotates at a high speed under motor 1's drive and produces centrifugal force, back taper hole 3 has been seted up around motor 1 on the casing 7 bottom surface, casing 7 overcoat is equipped with air ducting 4 for the hot guiding wind of transmission dries the droplet after atomizing disk 2 atomizing, and in getting into the drying tower of epilogue under guiding wind's drive, air-out end and the bottom surface of casing 7 of air ducting 4 flush.

When the drying tower is used, the motor 1 is started, the linear speed is generally regulated and controlled at 150-200m/s, the material liquid flows to the atomizing disc 2 through the inverted cone holes 3 in the bottom surface of the shell 7, the material is horizontally thrown out due to the action of centrifugal force in the contact process of the material and the atomizing disc 2 rotating at high speed to form fog drops with small diameter, the fog drops are immediately contacted with hot guide air guided out by the air guide device 4 after being formed, and moisture is evaporated to dry the material and enter a subsequent drying tower under the drive of the guide air.

According to the invention, materials can uniformly drop on the atomizing disc 2 through the inverted cone holes 3 on the bottom surface of the shell 7, and agglomeration is not easy to cause so as to influence the dispersion effect of the atomizing disc 2; through being equipped with air ducting 4 at casing 7 overcoat, and guarantee that air-out end of air ducting 4 flushes with casing 7's bottom surface, can make the fog drop after atomizing disk 2 atomizes carry out evaporation drying with hot-blast contact at once, promote drying efficiency greatly for atomizing disk 2's rotational speed can further promote.

In order to adjust the spraying amount of the atomizing device conveniently, the motor 1 is a variable frequency motor, and stepless speed regulation can be realized, so that the spraying amount of the atomizing device is changed by adjusting the rotating speed of the motor 1, and the granularity of a dried object is adjusted.

In order to improve the atomization uniformity of the atomization device and prevent splashing in the process of dispersing liquid drops, the atomization disc 2 is of a stepped structure, compared with the original disc-shaped structure, centrifugal force is generated after the material rotates at a high speed, and the liquid drops can be dispersed more uniformly after being buffered by the stepped atomization disc 2, so that the splashing phenomenon is not easily caused.

In order to guarantee the smoothness of material unloading, prevent to cause the jam, back taper hole 3 carries out polishing treatment for the internal surface in back taper hole 3 is smooth, guarantees the homogeneity of material in the whereabouts process.

In order to facilitate the disassembly and maintenance of the motor 1 in the shell 7, a mounting flange 6 is mounted on the upper end face of the shell 7, and the shell 7 is mounted on the mounting base 5 through the mounting flange 6.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, and the scope of protection is still within the scope of the invention.
