Description

Rotary flash dryer

Technical Field

The utility model relates to the technical field of drying equipment, in particular to a rotary flash evaporation dryer.

Background

The rotary flash evaporation dryer is a novel continuous drying device integrating drying, crushing and screening, and is particularly suitable for drying cake-shaped, paste-shaped and slurry-shaped materials. The drying time of the wet material in the drying tower is only 5-8 seconds, the moisture is evaporated instantly, and the quality of the dried product is greatly related to the drying temperature, the drying wind speed, the drying wind quantity and the crushing speed. The existing spin flash dryer is fixed in structure and single in function, only stirring blades used for crushing materials are arranged at the bottom of the drying cylinder, the situation that the materials are not completely crushed and are taken out of the drying cylinder by hot air can occur in the using process, dead angles exist at the bottom of the drying cylinder, and partial materials cannot be driven by the hot air to flow upwards, so that the bottom of the machine barrel is blocked, and the drying effect is influenced to a certain extent.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect that the existing drying cylinder can not crush materials completely, the utility model provides a rotary flash evaporation dryer,

the technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a spin flash dryer, includes drying cylinder, pan feeding pipe, discharging pipe and stirring rake, and the drying cylinder middle part is provided with the pan feeding pipe of taking the hopper, and the drying cylinder top is provided with the discharging pipe, and the drying cylinder bottom is provided with stirring rake one, is provided with stirring rake two in the hopper, and the drying cylinder bottom is provided with and is used for the hot-blast wind dish of jetting, and wind dish upper surface equipartition jetting pipe, the fan intercommunication of tuber pipe and outside area heater is passed through to wind dish bottom.

Further, a feeding auger is arranged in the feeding pipe, one end of the feeding auger extends into the drying cylinder, and the other end of the feeding auger extends to the position right below the hopper.

Furthermore, the air pipe and the fan form a group of air supply units, and two groups of air supply units are symmetrically arranged at the bottom of the air disc.

Further, the wind plate is horizontally arranged below the stirring paddle, and the outer edge of the wind plate is provided with an inclined plane attached to the inner wall of the drying cylinder.

Furthermore, the stirring paddle is horizontally arranged in the hopper through a mounting cross rod arranged at the bottom of the hopper.

The utility model has the advantages that the stirring paddle arranged in the hopper is used for primarily crushing the materials, and the stirring paddle arranged in the drying cylinder is used for secondarily crushing the materials, so that the crushing effect of the materials is ensured, and the drying effect is improved; through setting up the wind dish in drying barrel bottom, guarantee that the jetting is dry even, stop the appearance at dead angle, avoid the barrel bottom to block up, improve drying efficiency.

Drawings

The utility model is further illustrated with reference to the following figures and examples.

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

fig. 2 is an enlarged view at a in fig. 1.

In the figure, 1, a drying cylinder, 2, a feeding pipe, 3, a discharging pipe, 4, a first stirring paddle, 5, a second stirring paddle, 6, an air disk, 7, an injection pipe, 8, an air pipe, 9, a fan, 10, a feeding auger, 11, an inclined plane and 12 are provided with cross bars.

Detailed Description

As shown in fig. 1, which is a schematic structural diagram of the present invention, a spin flash dryer includes a drying cylinder 1, a feeding pipe 2, a discharging pipe 3 and a stirring paddle, the feeding pipe 2 with a hopper is arranged in the middle of the drying cylinder 1, the discharging pipe 3 is arranged at the top end of the drying cylinder 1, the first stirring paddle 4 is arranged at the bottom of the drying cylinder 1, the second stirring paddle 5 is arranged in the hopper, an air disk 6 for blowing is arranged at the bottom of the drying cylinder 1, blowing pipes 7 are uniformly distributed on the upper surface of the air disk 6, and the bottom of the air disk 6 is communicated with a fan 9 with a heater outside through an air pipe 8.

During the use, inject into wind dish 6 after the heater heating with the outside air through fan 9, and blow in drying cylinder 1 from the jetting pipe 7 of wind dish 6 upper surface, put into the hopper with the material simultaneously, the preliminary kibbling material of second 5 via the stirring rake gets into in drying cylinder 1 under the drive of pay-off auger 10, the hot-air that blows off in jetting pipe 7 upwards flows, the tiny material that the hot-air will tentatively smash the completion back and form blows air drying, and blow the material and flow from discharging pipe 3 on drying cylinder 1 top, the heavier large granule material of moisture then drops downwards, it is dry to blow up by the hot-air again after the stirring of first 4 via the stirring of stirring rake is smashed, and flow from discharging pipe 3 on drying cylinder 1 top.

A feeding auger 10 is arranged in the feeding pipe 2, one end of the feeding auger 10 extends into the drying cylinder 1, and the other end of the feeding auger 10 extends to the position right below the hopper. The feeding auger 10 is more beneficial to stably feeding materials into the drying cylinder 1.

The air pipe 8 and the fan 9 form a group of air supply units, and two groups of air supply units are symmetrically arranged at the bottom of the air disc 6. Wind energy is provided for the wind disc 6 through the two groups of air supply units, so that the sufficient wind source is ensured, and the materials are effectively dried.

The second stirring paddle 5 is arranged in the hopper through a mounting cross rod 12 which is horizontally arranged at the bottom of the hopper. The mounting cross rod 12 is welded and fixed at the bottom of the hopper and used for stably mounting the second stirring paddle 5, and materials put into the hopper are preliminarily crushed under the stirring of the second stirring paddle 5 and fall into the feeding auger 10 right below.

As shown in figure 2, the air disk 6 is horizontally arranged below the first stirring paddle 4, and the outer edge of the air disk 6 is provided with an inclined surface 11 attached to the inner wall of the drying cylinder 1. The inclined plane 11 is inclined upwards, so that the material can be effectively prevented from falling to the bottom of the drying cylinder 1, and the blockage of the bottom of the cylinder is avoided.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
