Description
Technical Field
The invention relates to an airflow dryer, and belongs to the technical field of material drying.
Background
The pneumatic drier is characterized in that when wet materials enter the pneumatic drier, the wet materials are subjected to high-speed strong crushing in sucked hot air, and the materials are quickly refined and quickly dehydrated through the collision, friction and shearing actions of the materials. The material moving upwards is acted by the rotary grading device, and the coarse and undried material returns to the crushing section and continues to be crushed and dried.
In the drying process of the existing materials, the temperature of air is gradually reduced in the upward conveying process of the air flow, so that the drying heat requirement of the materials cannot be completely met, the drying effect and the stability of the materials cannot be favorably ensured, and further improvement is needed.
Disclosure of Invention
The invention aims to overcome the defects and aims to provide the airflow dryer which is reasonable in structure and can effectively and uniformly dry materials.
The technical scheme adopted by the invention is as follows: the device comprises a conveying pipe (1), wherein a fan (2) is arranged at the bottom of the conveying pipe (1), a charging barrel (3) is arranged at the middle lower part of the conveying pipe (1), and a secondary heating device (4) is arranged at the middle upper part of the conveying pipe (1).
And a material crushing device is arranged at the lower part of the charging barrel (3) in the conveying pipe (1).
And a temperature monitoring device arranged at the lower part of the secondary heating device (4) is arranged on the conveying pipe (1).
Conveyer pipe (1) upper portion is provided with speedtransmitter, be provided with on fan (2) and receive the controlling means of speedtransmitter signal, controlling means control the air output and the air-out speed of fan (2).
And a cyclone dust collector is arranged at the rear part of the conveying pipe (1).
The crushing device comprises a rotating crushing disk (5), and crushing blades (6) rotating along with the crushing disk (5) are arranged on the crushing disk (5).
The lower part of the crushing device is provided with a sieve plate.
The invention has the advantages that: 1) according to the invention, the secondary heating device is arranged on the conveying pipe, and heat required by the secondary heating device can be conveyed from the outside, so that materials can be heated secondarily in the upward conveying process, and the drying effect of the materials is ensured;
2) the speed sensor is further arranged on the conveying pipe, and the air outlet quantity and the air outlet speed of the fan are controlled, so that the working state of the fan can be adjusted according to the actual state of the material when moving upwards, the energy consumption of the fan is reduced as far as possible on the basis of ensuring the material drying effect, the energy-saving effect is achieved, and the material drying cost is reduced.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
In the figure, 1 is a conveying pipe, 2 is a fan, 3 is a charging barrel, 4 is a secondary heating device, 5 is a crushing disk, and 6 is a crushing knife.
Detailed Description
The device comprises a conveying pipe 1, wherein a fan 2 is arranged at the bottom of the conveying pipe 1, a charging barrel 3 is arranged at the middle lower part of the conveying pipe 1, and a secondary heating device 4 is arranged at the middle upper part of the conveying pipe 1.
And a material crushing device is arranged at the lower part of the charging barrel 3 in the conveying pipe 1.
And a temperature monitoring device arranged at the lower part of the secondary heating device 4 is arranged on the conveying pipe 1.
The utility model discloses a fan, including conveyer pipe 1, fan 2, control device, conveyer pipe 1 upper portion is provided with speedtransmitter, be provided with on fan 2 and receive the controlling means of speedtransmitter signal, controlling means control the air output and the air-out speed of fan 2.
And a cyclone dust collector is arranged at the rear part of the conveying pipe 1.
The crushing device comprises a rotating crushing disk 5, and crushing blades 6 rotating along with the crushing disk 5 are arranged on the crushing disk 5.
The lower part of the crushing device is provided with a sieve plate.
The working process of the invention is as follows: the material enters the conveying pipe from the charging barrel 3, flows upwards under the blowing of the lower fan 2, is dried by the material blown by the fan 2 at the moment, and monitors the temperature of the material in real time by the temperature monitoring device in the process of flowing upwards, so that whether the upper secondary heating device 4 is put into use or not is determined; the speed sensor monitors the speed of the material in real time in the upward movement process of the material, if the speed of the material is monitored to be too low, the wind power is too small, the drying effect of the material and the upward movement power cannot be guaranteed, and the wind speed and the wind volume of the fan 2 are increased to solve the problems; if the speed of monitoring the material is too fast, the running time of the material in the conveying pipe 1 is too short, the drying effect of the material is also influenced, and at the moment, the control device controls the wind speed and the wind power of the fan 2 to be reduced, so that the drying effect of the material is ensured.
Meanwhile, the lower part of the conveying pipe 1 is provided with a crushing device, and the preferable crushing device adopts the structural form of a crushing disc 5 and a crushing knife 6, so that the crushing efficiency of falling materials is improved.
The crushing cutter 6 adopts a rotary structural form, so that the crushing effect of the materials can be fully ensured, the arrangement of the sieve plate at the lower part can effectively filter the materials, and the crushed materials can be ensured to enter the charging barrel again for drying.
The sieve plate is further designed into a double-open structure, so that the sieve plate is convenient to draw out and clean.
