Description

Vacuum rake dryer

Technical Field

The utility model relates to the technical field of drying equipment, in particular to a vacuum rake dryer.

Background

The rake dryer is designed by strengthening and improving various materials in a slurry state, a paste state, a granular state, a powder state, a fiber state and the like on the basis of the technology of the domestic traditional vacuum rake dryer, a transmission part adopts a cylindrical gear speed reducer which works stably and durably, a driving shaft adopts a thickened solid shaft, and the stable operation of the vacuum rake dryer under various severe working environments is fully ensured. The dried material is added from the middle above the shell, under the stirring of the continuous forward and reverse rotating rake teeth, the material moves back and forth axially, the surface contacted with the inner wall of the shell is continuously updated, the material is indirectly heated by steam, the rake teeth are uniformly stirred, the crushing rod crushes the material, so that the moisture on the surface of the material is more favorably discharged, and the gasified moisture is discharged from the outlet of the vacuum pump through the dry dust collector, the wet dust collector and the condenser. The existing rake dryer can not stir materials between the stirring rod and the rotating shaft well in the stirring process, so that the materials are not dried uniformly, and the drying quality of the materials is influenced to a certain extent.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defect of single structure of the existing stirring rod, the utility model provides a vacuum rake dryer, which solves the problem by the stirring rods with cross rods arranged in a staggered manner.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a vacuum rake dryer, includes drying cylinder and the puddler of setting in drying cylinder, and drying cylinder top is provided with the pan feeding mouth, and drying cylinder below is provided with the discharge gate, and the puddler mainly comprises the pivot that the level set up in drying cylinder and the crisscross rake lever that sets up in the pivot outside, and the rake lever outside is crisscross to be provided with the horizontal pole, and the rake lever tip is provided with the scraper blade of laminating drying cylinder inner wall.

Furthermore, the bottom surface of the drying cylinder is symmetrically arranged inclined planes which are symmetrically arranged at two sides of the discharge hole.

Furthermore, airbags are symmetrically arranged on two sides of the feeding port, and a steam inlet is formed above each airbag.

Furthermore, a plurality of air holes communicated with the drying cylinder are uniformly formed below the air bag.

Furthermore, the scraper consists of a mounting seat connected to the end part of the harrow bar and a material plate arranged in the mounting seat.

The utility model has the advantages that materials are stirred by the staggered harrow rods and the cross rods staggered on the harrow rods, so that the materials are uniformly stirred, and the stirring blind area is avoided, thereby ensuring better drying effect; the hot steam is preliminarily collected through the air bag, so that the damage to the inner wall of the drying cylinder caused by the impact of the steam is avoided, and the service life of the drying cylinder is prolonged.

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.

In the figure, 1 is a drying cylinder, 2 is a feeding port, 3 is a discharging port, 4 is a rotating shaft, 5 is a rake rod, 6 is a cross rod, 7 is an inclined plane, 8 is an air bag, 9 is a steam inlet, 10 is a mounting seat, and 11 is a material plate.

Detailed Description

As shown in fig. 1, which is a schematic structural diagram of the present invention, a vacuum rake dryer comprises a drying cylinder 1 and a stirring rod arranged in the drying cylinder 1, wherein a feeding port 2 is arranged above the drying cylinder 1, a discharging port 3 is arranged below the drying cylinder 1, the stirring rod mainly comprises a rotating shaft 4 horizontally arranged in the drying cylinder 1 and rake rods 5 staggered outside the rotating shaft 4, cross rods 6 are staggered outside the rake rods 5, and end portions of the rake rods 5 are provided with scrapers attached to an inner wall of the drying cylinder 1.

During the use, will treat that dry material adds from pan feeding mouth 2 of drying cylinder 1 top, inputs hot steam through gasbag 8 and steam inlet 9 in to drying cylinder 1, and the material is through the stirring of the rake arm 5 and the horizontal pole 6 of crisscross setting under the steam heating state, carries out even drying, discharges from discharge gate 3 of drying cylinder 1 below afterwards, accomplishes the drying.

The bottom surface of the drying cylinder 1 is symmetrically provided with inclined planes 7, and the inclined planes 7 are symmetrically arranged at two sides of the discharge hole 3. The inclination angle of the inclined plane 7 is not more than 15 degrees, and the stirring drying is not influenced, so that the discharging is convenient.

The two sides of the feeding port 2 are symmetrically provided with air bags 8, and a steam inlet 9 is arranged above each air bag 8. The hot steam is preliminarily stored in the air bag 8, and can be buffered, so that the damage to the inner wall of the barrel caused by the hot steam discharged by spraying is avoided.
