Description
Technical Field
The invention relates to a spiral feeder, in particular to a double-spiral variable-pitch spiral feeder of a continuous feeding device of a vacuum drier.
Background
The existing vacuum type drying machines are operated intermittently, the vacuum continuous operation is difficult to realize, the main problem is the feeding problem, and the continuous concentrate equipment is difficult to keep constant vacuum degree and maintain stable feeding speed. The reason is that the dryer is in a negative pressure state, the conveyor is in a normal pressure state, if the pressure maintaining effect cannot be achieved, the phenomenon of poor sealing occurs, the dryer cannot maintain high vacuum degree, and the vacuum drying effect cannot be achieved.
Disclosure of Invention
The invention aims to overcome the defects and provides the spiral feeder which is reasonable in structure and realizes continuous drying operation production.
The technical scheme adopted by the invention is as follows: the device comprises a conveying bin (1), wherein a feeding hole (2) is formed in one end of the conveying bin (1), and a discharging hole (3) is formed in the other end of the conveying bin (1);
a rotating shaft (4) is arranged in the conveying bin (1), and a spiral blade (5) is arranged on the rotating shaft (4); along feed inlet (2) to discharge gate (3) direction, the space between helical blade (5) and transport storehouse (1) inner wall reduces gradually.
The pitch of the helical blades (5) is gradually reduced along the direction from the feed port (2) to the discharge port (3), and the size of the conveying bin (2) is consistent.
Two groups of rotating shafts (4) which are arranged in parallel are arranged in the conveying bin (1), and the helical blades (5) on the two rotating shafts (4) are arranged in a helical reverse direction.
The pitches of the helical blades (5) are reduced in an equal difference mode.
The two ends of the conveying bin (1) are provided with rotating devices (6) for supporting the conveying bin (1), and the rotating device (6) at one end is provided with a driving device (7) for driving the conveying bin (1) to rotate.
The invention has the advantages that: the invention provides a double-helix variable-pitch spiral feeder for realizing continuous feeding of a vacuum drier and ensuring the vacuum degree of the drier, which can ensure the internal vacuum degree of the vacuum drier while meeting quantitative conveying of materials and realize continuous drying operation and production.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a conveying bin, 2 is a feeding hole, 3 is a discharging hole, 4 is a rotating shaft, 5 is a helical blade, 6 is a rotating device, and 7 is a driving device.
Detailed Description
The invention comprises a conveying bin 1, wherein a feeding hole 2 is formed in one end of the conveying bin 1, and a discharging hole 3 is formed in the other end of the conveying bin 1;
a rotating shaft 4 is arranged in the conveying bin 1, and a spiral blade 5 is arranged on the rotating shaft 4; along the direction from the feed inlet 2 to the discharge outlet 3, the space between the helical blade 5 and the inner wall of the conveying bin 1 is gradually reduced.
The pitch of the helical blades 5 is gradually reduced along the direction from the feed port 2 to the discharge port 3, and the size of the conveying bin 2 is consistent.
Two groups of rotating shafts 4 which are arranged in parallel are arranged in the conveying bin 1, and the helical blades 5 on the two rotating shafts 4 are arranged in a helical reverse direction.
The pitches of the helical blades 5 are reduced in an equal difference mode.
And two ends of the conveying bin 1 are provided with a rotating device 6 for supporting the conveying bin 1, and the rotating device 6 at one end is provided with a driving device 7 for driving the conveying bin 1 to rotate.
The screw pitch of the double-screw feeder is changed, the pitch at the feeding end is large, the pitch at the discharging end is small, the pitch distance at the front end of the conveying bin 1 is large in the conveying process of materials, the volume of the materials is large after the materials enter, the volume between the two spiral blades 5 is reduced along with the reduction of the pitch in the conveying process, the materials which are originally relatively fluffy are extruded by the spiral blades 5 to be more compact, the pitch is smaller, the materials are pressed to be more compact in the conveying process, a good sealing effect is achieved, and meanwhile, in the compacting process, the hollowing phenomenon cannot occur due to the fact that the negative pressure inside the drying machine is higher.
The double-helix feeding device has the advantages that the double-helix feeding device has a self-cleaning function, and meanwhile, the material conveying capacity can be further improved.
