Description

Technical Field

[0001] The utility model relates to the technical field of chemical product processing, in particular to a device for rapidly heating and condensing materials. Background Art

[0002] At present, the existing domestic methods for heating and cooling materials in the chemical industry mainly include jacketed double-layer reactors to produce finished products, followed by built-in coil stirring production, and finally internal and external coil bidirectional reactors.

[0003] The jacketed enamel reactor is heated and cooled between the outer jacket and the inner cylinder, and the heat exchange or cooling is carried out on the whole surface, so the reaction time is long and the cost is high. The built-in coil type goes directly into the tank, and the effect is better than the jacket, but the efficiency is average due to the long pipeline. The inner and outer double coils are more efficient than the first two, but because the pipelines are long and there is no deflection during the stirring process, the ideal effect cannot be achieved.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In this embodiment, refer to Figure 1A device for rapidly heating and condensing materials comprises a kettle shell 1 and an end cover 2, the end cover 2 being designed as a dome structure, and a feed port 8 is arranged on the end cover 2. The upper end cover 2 and the lower kettle shell 1 are connected by upper and lower docking flanges 9, a transmission shaft arranged at the output end of a motor reducer 3 arranged at the top of the end cover 2 is rotatably connected to a stirring shaft 5 through a coupling 4, the stirring shaft 5 is vertically inserted into the interior of the kettle shell 1, a multi-layer stirring blade 6 is arranged on the shaft of the stirring shaft 5, an anchor-shaped stirring paddle 7 is arranged at the bottom of the stirring shaft 5, and a baffle 11 is arranged on the inner wall of the kettle shell 1.

[0020] The stirring shaft 5 rotates clockwise at a constant speed to stir the materials in the kettle body and fully blend them. During the stirring process, a vortex phenomenon will be generated, and the liquid will hit the baffle 11 on the tank wall to form a vortex phenomenon.

[0021] A double-layer inner coil is arranged on the inner side of the baffle 11 and is respectively designed as an inner coil type A 15 and an inner coil type B 16. Both the inner coil type A 15 and the inner coil type B 16 are disc-shaped pipes. The inner coil type B 16 is located on the inner side of the inner coil type A 15. At the same time, the pitch and diameter of the inner coil type A 15 are greater than the pitch and diameter of the inner coil type B 16. An outer coil is arranged on the outer wall of the kettle shell 1.

[0022] Here, the inner coil is set with two turns and the outer coil is set with one turn. When the material is stirred, the two-way flow of the outer coil and the inner coil can quickly heat up or cool down, thus saving time.

[0023] As attached Figure 1 As shown,

[0024] Regarding the structure of the inner coil A type 15: the inner coil A type 15 has a pipeline area divided into an upper section of the inner coil A type I section 1501 and a lower section of the inner coil A type II section 1502;

[0025] Regarding the structure of the inner coil B type 16: the pipe area of ​​the inner coil B type 16 is divided into the upper half of the B type inner coil I section 1601 and the B type inner coil II section 1602;

[0026] Regarding the structure of the external coil: the pipeline of the external coil is divided into the upper section of the external coil A section 12, the middle section of the external coil B section 13 and the bottom lower head coil C section 14.

[0028] Each coil is divided into several sections, so that the opening and closing of each section port can be selectively controlled according to the actual processing needs. With this design, the temperature rise or cooling in the kettle can be instantly controlled, and the temperature can be adjusted at will. Because the coils are separated, the pressure of the fluid in the coil can be increased, and the temperature rise and fall can be accelerated or slowed down, thereby controlling costs, improving efficiency, and increasing output.

[0029] Finally, it should be supplemented that the bottom surface of the kettle shell 1 is convex downward to form an arch surface, and a discharge port 10 is opened in the center of the arch surface, through which the material can be discharged to the outside.
