Description

Technical Field

[0001] The utility model relates to a micro nitrogen supplement structure for a food-grade rPET detoxification and viscosity increasing device, belonging to the technical field of detoxification and viscosity increasing devices. Background Technique

[0002] The technology of detoxification and viscosity increasing devices has significantly extended the recycling life cycle of PET, and greatly improved the resource efficiency and sustainability of PET by ensuring that the material quality does not decline during the recycling process. The recycling and utilization of non-degradable resources has a profound impact on achieving a true circular economy, not only reducing the demand for new materials, minimizing the impact on the environment, but also promoting the efficient and sustainable utilization of resources.

[0003] When the material reacts in the detoxification and viscosity increasing device, it may encounter uneven air circulation, which will cause the impurities of the material to not be effectively removed and ultimately affect the quality of the particles.

[0004] Therefore, a micro nitrogen supplement structure for a food-grade rPET detoxification and viscosity increasing device is proposed. Content of the Utility Model

[0005] In view of this, the utility model provides a micro nitrogen supplement structure for a food-grade rPET detoxification and viscosity increasing device to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0006] The technical solution of the utility model is realized as follows: A micro nitrogen supplement structure for a food-grade rPET detoxification and viscosity increasing device includes a bottom plate. A nitrogen generator is fixedly installed on the top of the bottom plate. An injection pipe is connected to the left side of the nitrogen generator. A suction pump is fixedly installed on the right side of the nitrogen generator. The output end of the suction pump is connected to a first inlet pipe. A second inlet pipe is provided at one end of the first inlet pipe away from the suction pump. A pipe heater is fixedly installed on the surface of the second inlet pipe. The second inlet pipe is connected to a reaction chamber at one end away from the first inlet pipe. The reaction chamber is fixedly installed on the right side of the top of the bottom plate. A motor is fixedly installed at the bottom of the reaction chamber.

[0007] Further preferably, a gas flow counter is connected to one end of the first inlet pipe away from the suction pump. A display panel is fixedly installed on the front side of the gas flow counter. The second inlet pipe is connected to the right side of the gas flow counter. The first inlet pipe and the second inlet pipe are interconnected.

[0008] Further preferably, a support frame is fixedly installed on the top of the bottom plate. The top of the support frame contacts the bottom of the gas flow counter.

[0009] Further preferably, an air intake valve is fixedly installed at the middle end of the second air intake pipe, and an air valve switch is movably connected to the top of the air intake valve.

[0010] Further preferably, the four sides of the bottom plate surface are threadedly connected with anchor bolts, and the bottoms of the anchor bolts are threadedly connected to the ground.

[0011] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0012] 1. The utility model uses nitrogen to be heated by a pipeline heater and then measured and controlled by a gas flow counter under a certain pressure range. A small amount of high-temperature nitrogen is added into the reaction chamber to drive air flow, remove impurities and detoxify the materials in the reaction chamber.

[0013] 2. The utility model provides a gas flow counter, which can facilitate the understanding of the value of the injected nitrogen, and avoids excessive or insufficient nitrogen injection, which affects the removal of impurities and toxins inside the reaction chamber. The support frame can support the gas flow counter, and avoid the gas flow counter falling due to its own weight after long-term use. The air inlet valve and the air valve switch can be provided to manually control the switch when the nitrogen enters the reaction chamber, so that the injection of nitrogen can be stopped at any time. The anchor bolts can stabilize the entire equipment, and avoid the overall tipping of the equipment due to accidental collision.

[0026] After nitrogen is heated by the pipeline heater 8 and metered and controlled by the gas flow counter 6 under a certain range of pressure, a small amount of high-temperature nitrogen is supplemented into the reaction chamber 10 to drive the air flow and remove impurities in the materials in the reaction chamber 10 for detoxification.

[0027] Embodiment 2

[0028] As Figure 1-5As shown, in one embodiment, the end of the first air inlet pipe 5 away from the air pump 4 is connected to the gas flow counter 6, and a display panel 61 is fixedly installed on the front side of the gas flow counter 6. The second air inlet pipe 7 is connected to the right side of the gas flow counter 6. The first air inlet pipe 5 and the second air inlet pipe 7 are connected to each other. A support frame 13 is fixedly installed on the top of the base plate 1, and the top of the support frame 13 is in contact with the bottom of the gas flow counter 6. An air inlet valve 9 is fixedly installed on the middle end of the second air inlet pipe 7, and the top of the air inlet valve 9 is movably connected to the air valve switch 91. The four sides of the surface of the base plate 1 are threaded with anchor bolts 12, and the bottom of the anchor bolts 12 are threadedly connected to the ground.

[0029] By providing a gas flow counter 6, it is convenient to understand the value of the injected nitrogen, and avoid excessive or insufficient nitrogen injection, which affects the removal of impurities and toxins inside the reaction chamber 10. By providing a support frame 13, the gas flow counter 6 can be supported to avoid the gas flow counter 6 from falling due to its own weight after long-term use.

Then, the air valve switch 91 is turned to open the air inlet valve 9, so that the heated nitrogen enters the reaction chamber 10 through the second air inlet pipe 7 and begins to remove impurities and detoxify the materials in the reaction chamber 10.
