Abstract
The invention relates to a spin flash dryer, which comprises a barrel, a stirrer, a frame and a stirring power. The inner wall of the barrel of a crushing knife set area is of an equilateral polygon, and the exterior angle of the polygon is 5 to 10 degrees. A material is crushed by a blade in the past, the rotary blade has the crushing effect except that the material just falls down when the rotary wind and the rotary blade act together, the material rotates upwards together with airflow along the smooth inner wall after the material is driven to rotate, and the relative speed of the material and the bade is reduced to minimum so as to affect the crushing effect; and after being improved, the material generates impact effect on the inner wall of the equilateral polygon and changes the flying direction so that the speed of the material is reduced, the contact frequency of the material and the knife is increased and the yield is increased by 10 to 15 percent. The crushing knife set on the stirrer comprises a straight knife back assembly and a splayed knife back assembly, the crushing knife in the straight knife back assembly is fan-shaped, and an oblique angle between the blade and the horizontal plane is 8 to 10 degrees. The crushing knife has an upward force so as to increase the crushing effect by over 250 percent and reduce the wall adhering phenomenon.
Description
Technical field
The present invention relates to a kind of Rotatingandflashstreamingdrier.
Background technology
As shown in Figure 1, existing Rotatingandflashstreamingdrier comprises cylindrical shell, agitator, frame and stirring power, cylindrical shell, agitator and stirring power are installed on the frame, cylindrical shell drives the agitator rotation at the stirring power of described cylindrical shell, has the cutter of pulverizing group on the agitator, pulverize the cutter group and be installed in the rotating shaft of agitator, the cylinder inboard wall of pulverizing cutter group zone is circular, and material grinding only relies on pulverizes the cutter comminuting matter.The pulverizing cutter of pulverizing simultaneously in the cutter group is a yi word pattern, two blades, and rotational line speed is 20M/S.
Summary of the invention
Technical problem to be solved by this invention is: it is better to design a kind of drying effect, simultaneously more energy-conservation Rotatingandflashstreamingdrier.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Rotatingandflashstreamingdrier, comprise cylindrical shell, agitator, frame and stirring power, cylindrical shell, agitator and stirring power are installed on the frame, stir power and drive the agitator rotation, has the cutter of pulverizing group on the agitator, pulverize the cutter group and be installed in the rotating shaft of agitator, the cylinder inboard wall of pulverizing cutter group zone is an equilateral polygon, and polygonal exterior angle H is 5～10 degree.Originally only by the blade comminuting matter, when rotation wind-force and rotating blade one worked, removing had crushing effect when material has just fallen, after material is driven to rotate, material makes progress with air-flow along the smooth inner wall rotation, and it is minimum that the relative velocity of material and blade reduces to, and influences crushing effect, after the improvement, material produces effect of impact on the equilateral polygon cylinder inboard wall, the change of flight direction reduces material speed, increase the frequency of exposure of material and cutter, output increases 10-15%.
Pulverizing cutter group on the agitator comprises combination of straight knife bar and the combination of Eight characters knife bar, and the pulverizing cutter in the combination of straight knife bar is a fan type, and blade and horizontal plane have the oblique angle of 8～10 degree.This pulverizing cutter has a power that makes progress, and increases crushing effect and reaches more than 250%, for glutinous wall material, reduces glutinous wall phenomenon.
Pulverizing cutter in the combination of straight knife bar has three blades.
The combination of straight knife bar is made up of three layers of pulverizing cutter.
The linear velocity of the pulverizing cutter rotation in the combination of straight knife bar is 40～45M/S.
The invention has the beneficial effects as follows: originally only by the blade comminuting matter, when rotation wind-force and rotating blade one worked, removing had crushing effect when material has just fallen, after material is driven to rotate, material makes progress with air-flow along the smooth inner wall rotation, and it is minimum that the relative velocity of material and blade reduces to, and influences crushing effect, after the improvement, material produces effect of impact on the equilateral polygon cylinder inboard wall, the change of flight direction reduces material speed, increase the frequency of exposure of material and cutter, output increases 10-15%.This pulverizing cutter has a power that makes progress to material, increases crushing effect and reaches more than 250%, for glutinous wall material, reduces glutinous wall phenomenon.By the improvement to barrel and blade, this Rotatingandflashstreamingdrier can save energy 10～15%

The specific embodiment
Rotatingandflashstreamingdrier shown in Fig. 2,3,4 and 5, comprise cylindrical shell 1, agitator, frame 3 and stir power, cylindrical shell 1, agitator and stirring power are installed on the frame 3, stir power and drive the agitator rotation, agitator has the cutter of pulverizing group, pulverize the cutter group and be installed in the rotating shaft of agitator, the cylinder inboard wall of pulverizing cutter group zone is an equilateral polygon, and polygonal exterior angle H is 5～10 degree.
Pulverizing cutter group on the agitator comprises combination 5 of straight knife bar and Eight characters knife bar combination 6, and the pulverizing cutter 51 in the straight knife bar combination 5 is a fan type, and blade and horizontal plane have the oblique angle of 8～10 degree.Pulverize cutter 51 three blades are arranged.Straight knife bar combination 5 is made up of three layers of pulverizing cutter 51.The linear velocity of pulverizing cutter 51 rotations is 40～45M/S.51 pairs of materials of this pulverizing cutter have a power that makes progress, and increase crushing effect and reach more than 250%, for glutinous wall material, reduce glutinous wall phenomenon.But manufacture difficulty height.The high 30%-35% of manufacturing cost needs the school static and dynamic equilibrium.The accuracy of manufacture and testing accuracy height.
Material is added in the cylindrical shell 1 by charging aperture 7, thermal current enters from air inlet 8, material under the acting in conjunction of hot blast and agitator to material produce strong shearing, blow floating, rotation, pulverization, so material is by little materialization and dry, dry material passes through discharging opening 9 dischargings under the carrying of hot blast.
