Abstract
The invention relates to a gradually-changing diameter type drying machine with hollow blades. The device comprises a cylinder body (1) and a hollow blade (2) arranged in the cylinder body (1) and used for conveying materials, wherein a material pushing scraper (3) is arranged at the end part of the hollow blade (2); along the direction from the feeding end to the discharging end, the diameter of the hollow blade (2) is gradually increased, and the length of the corresponding material pushing scraper (3) is gradually reduced. The invention aims to improve the blade structure of the hollow blade, increase the propelling force of the blade, quickly push viscous materials to the rear end for even distribution, and maximally utilize the effective heat exchange area.
Description
Technical Field
The invention relates to a gradually-variable-diameter type drying machine with hollow blades, and belongs to the technical field of drying machinery.
Background
When the hollow blade dryer is used for drying materials (such as sludge) with large viscosity, the viscosity of the sludge is large, the spiral angle of the blades is small, the propelling force is small, the flowing speed of the materials is low, and the materials are accumulated at the feeding end after being fed. And the rear end has no or little material, which causes great waste of heat exchange area, thus being to be improved.
Disclosure of Invention
The invention aims to overcome the defects and provides the gradually-changing hollow blade type dryer which is reasonable in structure and can improve the service performance of the dryer.
The technical scheme adopted by the invention is as follows: the gradually-changing-diameter type drying machine with the hollow blades comprises a cylinder body (1) and hollow blades (2) arranged in the cylinder body (1) and used for conveying materials, wherein pushing scrapers (3) are arranged at the end parts of the hollow blades (2);
along the direction from the feeding end to the discharging end, the diameter of the hollow blade (2) is gradually increased, and the length of the corresponding material pushing scraper (3) is gradually reduced.
The barrel (1) is internally provided with an installation shaft (4) used for installing the hollow pressing sheet (2) and the pushing scraper (3), and the installation shaft (4) is internally provided with a pipeline (5) used for introducing a heat medium.
A cavity is arranged in the mounting shaft (4), and the pipeline (5) is mounted in the cavity, so that the heat medium forms a circulating channel in the cavity.
Along the direction from the feeding end to the discharging end, the material pushing scraper (3) is integrally arranged on the hollow blade (2).
Half of the hollow blades (2) and the pushing scrapers (3) are arranged straightly, and the thickness of the other half of the hollow blades is gradually reduced.
The invention has the advantages that: the invention aims to improve the blade structure of the hollow blade, increase the propelling force of the blade, quickly push viscous materials to the rear end for even distribution, and maximally utilize the effective heat exchange area.

FIG. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a cylinder, 2 is a hollow blade, 3 is a pushing scraper, 4 is a mounting shaft, and 5 is a pipeline.
Detailed Description
The hollow blade gradually-changing diameter type drying machine comprises a cylinder body 1 and hollow blades 2 arranged in the cylinder body 1 and used for conveying materials, wherein pushing scrapers 3 are arranged at the end parts of the hollow blades 2;
along the direction from the feeding end to the discharging end, the diameter of the hollow blade 2 is gradually increased, and the length of the corresponding material pushing scraper 3 is gradually reduced.
The barrel 1 is internally provided with an installation shaft 4 for installing the hollow pressing sheet 2 and the pushing scraper 3, and the installation shaft 4 is internally provided with a pipeline 5 for introducing a heat medium.
A cavity is provided in the mounting shaft 4 and the conduit 5 is mounted in the cavity such that the thermal medium forms a circulation channel in the cavity.
Along the direction from the feeding end to the discharging end, the material pushing scraper 3 is integrally arranged on the hollow blade 2.
And one half of the hollow blade 2 and the pushing scraper 3 are arranged straightly, and the other half of the hollow blade and the pushing scraper are arranged with gradually reduced thickness.
The invention reduces the diameter of the blade at the front section of the hollow blade, increases the length of the pushing scraper 3, gradually prolongs the diameter of the blade backwards, reduces the length of the scraper 3, increases the driving force of the front section, accelerates the material flowing speed, prevents the material from being accumulated at the feed inlet, and evenly distributes the material in the whole hollow blade cylinder 1, thereby improving the whole heat exchange efficiency.
