Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a mixing device for the production of modified PTFE. Background Technology

[0002] PTFE is a high-performance polymer material, originally used as a special engineering plastic. Due to its excellent chemical stability, electrical insulation, extremely low coefficient of dynamic friction, non-flammability, and chemical corrosion resistance, it is known as the "King of Plastics". However, it has poor creep resistance and low surface hardness. Therefore, it needs to be modified and added during use. Currently, there are two types of modification additives: inorganic and organic. Different additives can meet the requirements of different working conditions.

[0003] A search revealed that Chinese patent CN218535218U discloses a PTFE production line mixer, including a top plate. Each of the four bottom corners of the top plate is fixedly connected to a column. A mixing cylinder is detachably connected to the bottom of the top plate. An auger, rotatably connected to the top plate, is located inside the mixing cylinder. A feed pipe is fixedly connected to one side of the top plate, and a matching guide pipe is fitted around the outside of the auger.

[0004] In actual use, this patent has the following drawbacks:

[0005] When mixing PTFE raw materials in a mixer, a motor is needed to drive the auger and stirring rod to rotate. The auger and stirring rod rotate in a relatively unidirectional direction, which leads to uneven mixing of the PTFE raw materials and reduces the mixing effect of the mixer. Utility Model Content

[0006] In view of the technical problem that the rotation direction of the auger and stirring rod in the existing technology is relatively uniform, resulting in uneven mixing of PTFE raw materials, this utility model provides a mixing device for modified PTFE production.

[0007] The technical solution adopted by this utility model is: a mixing device for modified PTFE production, including a mixing frame and a stirring rod. The stirring rod is disposed within the mixing frame, and a mixing assembly for completely mixing PTFE raw materials is disposed within the mixing frame. The mixing assembly includes a rotating plate, a first gear, a second gear, a circular plate, a third gear, a gear ring plate, a paddle, a fixed plate, a circular ring plate, and a motor. The rotating plate is rotatably mounted on the top of the inner wall of the mixing frame. The first gear is rotatably mounted on the bottom of the rotating plate, and the second gear is rotatably mounted on the bottom of the rotating plate. A circular groove is opened at the bottom of the rotating plate, and the circular plate is rotatably mounted in the circular groove. The circular plate is fixedly connected to the mixing frame, and the third gear is fixedly mounted on the bottom of the circular plate.

[0008] Furthermore, the stirring rod is fixedly installed at the bottom of the first gear, and the gear ring plate is fixedly installed at the top of the inner wall of the mixing frame.

[0009] Furthermore, the blade is fixedly installed at the bottom of the second gear, the fixing plate is fixedly installed at the bottom of the rotating plate, and the annular plate is fixedly installed on one side of the fixing plate.

[0010] Furthermore, the motor is fixedly installed on the top of the mixing frame, the rotating plate is connected to the output end of the motor, and a feeding trough is provided on the top of the mixing frame.

[0011] Furthermore, a cooling assembly for cooling the PTFE raw material during the mixing process is provided on one side of the mixing frame. The cooling assembly includes a cooling frame, a circulating cooling mechanism, a first connecting pipe, a second connecting pipe, and a discharge valve. The cooling frame is fixedly installed on the outside of the mixing frame.

[0012] Furthermore, the circulating cooling mechanism is disposed outside the cooling frame, the first connecting pipe is fixedly connected to the outside of the cooling frame, the second connecting pipe is fixedly connected to the outside of the cooling frame, the first connecting pipe is fixedly connected to the output end of the circulating cooling mechanism, and the second connecting pipe is fixedly connected to the input end of the circulating cooling mechanism.

[0013] Furthermore, a discharge trough is provided between the cooling frame and the mixing frame, and the discharge valve is fixedly installed in the discharge trough.

[0014] The beneficial effects of this utility model are:

[0015] This invention enables complete mixing of PTFE raw materials through a mixing component, thereby preventing uneven mixing of PTFE raw materials caused by the unidirectional rotation direction of the stirring rod and blades when the mixing device is mixing PTFE raw materials, thus increasing the mixing effect of the mixing device on PTFE raw materials.

[0016] Secondly, this invention uses paddles to move the PTFE material from the bottom to the top, thereby improving the mixing efficiency of the mixing device for PTFE material.
