Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene (PTFE) production technology, specifically to a processing device for producing PTFE. Background Technology

[0002] In the production of polytetrafluoroethylene (PTFE), corresponding processing equipment is required to process the raw materials.

A protective box is fixedly connected to the upper surface of the housing. Using a motor, the anti-corrosion material and raw materials can be stirred, allowing for more uniform mixing. However, as described in the aforementioned patent, existing processing equipment for PTFE production struggles to vacuum the gas trapped inside the housing before PTFE preparation, thus affecting subsequent processes. Furthermore, after PTFE preparation is complete, it is difficult to effectively cool and recover the high-temperature waste gas, potentially causing safety hazards. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a processing apparatus for producing polytetrafluoroethylene (PTFE), comprising a housing, wherein a processing component for PTFE processing is connected within the housing, the processing component comprising:

[0005] A stirring component is installed on the upper part of the housing for stirring materials. The stirring component includes a motor installed on the rear side of the top of the housing. A stirring frame is rotatably connected to the upper part of the housing. A bevel gear assembly for driving the stirring frame is connected to the output end of the motor. A guide tube is fixedly connected to the top of the housing and rotatably connected to the upper part of the stirring frame. A filter ring is provided on the upper side of the main shaft of the stirring frame.

[0006] An adjusting component, installed on the upper side of the housing, is used for vacuuming and waste gas regulation.

[0022] Please see Figure 1-4This utility model provides a technical solution: a processing device for producing polytetrafluoroethylene, including a housing 1, and a processing component for processing polytetrafluoroethylene connected inside the housing 1. The processing component includes a stirring component 2, which is installed on the upper end of the housing 1 for stirring materials. The stirring component 2 includes a motor 21 installed on the rear side of the top of the housing 1. A stirring frame 23 is rotatably connected to the upper end of the housing 1.

[0024] The storage tank 4 is installed on the top left side of the shell 1 for material introduction; the output end of the motor 21 is coaxially and fixedly connected to the active bevel gear in the bevel gear assembly 22, and the driven bevel gear in the bevel gear assembly 22 is coaxially and fixedly connected to the stirring frame 23. The inner end of the upper side of the main shaft of the stirring frame 23 is provided with a connecting groove that communicates with the guide tube 24 and the filter ring 25 respectively; the processing component 33 also includes a second valve 333 set at the bottom of the cooling shell 331, a return pipe is set at the rear side of the cooling tube 332 near the outer end of the cooling shell 331, the left side of the cooling shell 331 is fixedly connected to the right side of the guide tube 24, a drain pipe is set at the bottom of the second valve 333, and the regulating component 3 also includes a third valve 35 installed at the bottom of the shell 1, a discharge pipe is set at the upper right side of the third valve 35;

[0025] The bottom of the storage tank 4 is equipped with a fourth valve that is fixedly connected to the top of the shell 1. The top of the storage tank 4 is equipped with a feeding pipe. The inner wall of the shell 1 is equipped with a heating block that is electrically connected to an external controller. The vacuum pump 31, the first valve 32, the cooling shell 331, the recovery tank 334, the conduit 24, the stirring rack 23, and the filter ring 25 work together to achieve filtration and vacuuming of the inner end of the shell 1. During the filtration and vacuuming process inside the shell 1, the water supply component 34 supplies water to the cooling pipe 332, so that the gas passing through the cooling shell 331 is cooled by heat absorption. The activated carbon mesh 335 in the recovery tank 334 adsorbs odors and impurities in the gas, reducing the impact on subsequent polytetrafluoroethylene production.

[0026] The main difference between the second implementation method and the first implementation method is that:

[0027] The water supply component 34 includes a water pump 341 installed on the front side of the top of the housing 1. A water pipe 342 is provided at the upper drain end of the water pump 341. A three-way valve 343 is installed on the rear side of the water pipe 342. A first pipe 344 fixedly connected to the front side of the cooling pipe 332 is installed on the right side of the three-way valve 343. A second pipe 345 is installed on the left side of the three-way valve 343. A water spray strip 346 fixedly connected to the second pipe 345 is provided on the top of the inner side of the housing 1.

[0028] The water pump 341 is equipped with a water pumping pipe at the water pumping end, and the bottom of the spray bar 346 is equipped with several spray holes that are connected to the second pipe 345. The water pump 341, the water pumping pipe, the water supply pipe 342, the three-way valve 343, and the first pipe 344 cooperate with each other to achieve water supply treatment in the cooling pipe 332. After the polytetrafluoroethylene production is completed and discharged, the three-way valve 343 is reversed. At this time, the water pumped by the water pump 341 sprays and cleans the outer surface of the rotating stirring frame 23 and the outer surface of the filter ring 25 through the water supply pipe 342, the three-way valve 343, the second pipe 345, and the spray bar 346.

[0029] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0030] In use, the user opens the first valve 32 and starts the vacuum pump 31. The vacuum pump 31 evacuates the inside of the housing 1 through the first valve 32, the processing component 33, the conduit 24, the inner connecting groove at the upper end of the stirring rack 23, and the filter ring 25. After the vacuum inside the housing 1 is completed, the vacuum pump 31 and the first valve 32 are closed, and the fourth valve at the bottom of the storage tank 4 is opened. Under the action of gravity and external air pressure, the solution used to prepare polytetrafluoroethylene is introduced into the housing 1 through the fourth valve. Before the liquid at the bottom of the storage tank 4 is drained, the fourth valve is closed. After the material in the housing 1 is introduced, power is supplied to the heating block in the inner wall interlayer of the housing 1 so that the heating block heats the inner wall of the housing 1. The motor 21 is started. The motor 21 drives the stirring rack 23 through the bevel gear assembly 22 to heat and stir the liquid solution in the housing 1. The edge of the stirring rack 23 scrapes against the inner wall of the housing 1 to promote the removal of residual material adhering to the inner wall of the housing 1. After the polytetrafluoroethylene is prepared, the power supply to the heating block is stopped.

[0031] Open the third valve 35. Under the action of gravity, the mixture of prepared polytetrafluoroethylene material and other solutions is discharged through the third valve 35 and the discharge pipe. After the material is discharged, close the third valve 35 and start the water pump 341. The water pump 341 draws water from the external source through the water pumping pipe. Then the water is injected into the cooling pipe 332 through the water pipe 342 and the three-way valve 343. Then the water flows back to the water source through the return pipe. Open the first valve 32 and repeat the above vacuuming operation. At this time, when the gas passes through the cooling shell 331, the water flowing through the cooling pipe 332 absorbs heat and cools the gas through heat exchange. The liquid that liquefies upon cooling remains at the bottom of the cooling shell 331. When the liquid needs to be discharged, open the second valve 333. The liquid is discharged through the second valve 333 and the drain pipe. When the gas passes through the recovery tank 334, the activated carbon mesh 335 in the recovery tank 334 adsorbs the odor and harmful impurities in the gas, which helps in the subsequent production of polytetrafluoroethylene.
