Technical Field

[0001] This utility model relates to the field of water recycling technology, and in particular to an online recycling device for resin recycled materials. Background Technology

[0002] The mixture extracted under negative pressure in the resin production line includes water, oil, and recycled material, and the recycled material in the mixture needs to be recycled and reused.

[0003] However, existing technologies generally collect the mixture directly without separation, and then process the mixture in a later stage to recover the material. Since the mixture contains a large amount of oil and water, manual separation is required, which results in low efficiency and high cost of recovering the material, and the process is cumbersome and complicated.

[0004] Therefore, in order to solve the above problems, it is necessary to develop an online resin recycling device that can separate and collect recycled materials, oil and water online without the need for secondary processing, avoid the impact of oil and water on production efficiency, and achieve efficient and low-cost recycling of recycled materials.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0029] like Figure 1-2 As shown, an online separation and recycling device for resin recycled materials includes a reaction vessel 1, an oil-water separation component 2, a condenser 3, an oil collection component 4, a vacuuming component 5, a storage tank 70, and a water collection tank 80.

[0030] The vacuum port 1a of the reactor 1 is connected to the air inlet of the oil-water separation component 2 through the first connecting pipe assembly 6.

[0031] The first connecting pipe assembly 6 includes a first coil 61, a heating element 62, and a heat insulation layer 63;

[0032] The two ends of the first coil 61 are connected to the vacuum port 1a and the air inlet of the oil-water separation component 2, respectively, and the first coil 61 is wound around the heating element 62.

[0033] The insulation layer 63 is fitted onto the outside of the first coil 61;

[0034] The oil outlet of the oil-water separation component 2 is connected to the condenser 3 through the second connecting pipe 7, and the liquid outlet is connected to the storage tank 70. The oil-water separation component 2 is used to separate oil and water in the recovered material. The oil and water enter the condenser 3 through the second connecting pipe 7, and the recovered material enters the storage tank 70 after passing through the oil-water separation component 2.

[0035] The condenser 3 is connected to the oil collection assembly 4 via a third connecting pipe 8;

[0036] The oil collection component 4 is connected to the vacuum component 5 via the vacuum pipe 10, and the vacuum component 5 is connected to the water collection tank 80 via the water pipe 90.

[0037] In this embodiment, under the action of the vacuum assembly 5, the mixture generated by the continuous operation of the reactor 1 enters the oil-water separation assembly 2 through the first coil 61; during the process, the mixture before entering the oil-water separation assembly 2 is fully reacted by the high temperature heating of the first connecting pipe assembly 6.

[0038] Then, under the action of the oil-water separation component 2, the recovered material is separated from the oil and water. The oil and water enter the condenser 3 through the second connecting pipe 7. The oil and water are condensed and liquefied under the action of the condenser 3 and stored in the oil collection component 4. Then, the water in the oil and water is turned into water vapor and separated from the oil under the action of the vacuum component 5. Then the water vapor enters the water collection tank 80 through the water pipe 90.

[0039] This enables online separation and collection of recycled materials, oil, and water, eliminating the need for secondary processing and avoiding the impact of oil and water on production efficiency, thus achieving efficient and low-cost recycling of recycled materials.

[0040] In this embodiment, the reaction temperature can be controlled at 180-190 degrees Celsius by setting the first connecting pipe assembly 6, ensuring that the mixture reacts fully.

[0041] Furthermore, such as Figure 1 As shown, in order to improve the separation efficiency of recycled materials, the oil-water separation component 2 is a multi-stage oil-water separation component 2.

[0042] Furthermore, such as Figure 1 As shown, in order to improve the processing capacity of recycled materials and oil-water separation and enhance processing reliability, the oil-water separation component 2 includes at least two oil-water separators 9 connected in parallel.

[0043] In this embodiment, the parallel connection method is suitable for high flow scenarios, avoids overloading of a single oil-water separator 9, and reduces the cost of investing in a large oil-water separator 9.

[0044] Furthermore, such as Figure 1 As shown, in order to improve the separation efficiency and effect of the recycled material, the oil-water separation component 2 includes at least two oil-water separators 9 with different separation accuracies and connected in series.

[0045] In this embodiment, coarse separation is performed by a primary oil-water separator 9 to separate large particles or high-concentration oil phases; and residual fine oil droplets are separated by a secondary oil-water separator 9, thereby achieving efficient separation of recycled material and oil and water through step-by-step refining.

[0046] In this embodiment, the two-stage series connection can buffer changes in flow rate, avoid insufficient separation due to excessively high flow rate, and ensure system stability.

[0047] Furthermore, such as Figure 1 , 2As shown, the third connecting pipe 8 is a spiral coil.

[0048] In this embodiment, the third connecting pipe 8 of the coil structure can delay the residence time of oil and water in the condenser 3, so that the recovered material can be fully and evenly separated in the oil-water separation component 2, thereby improving the separation effect and effectively reducing the cost of recycled water.

[0049] Furthermore, such as Figure 1 As shown, the oil collection assembly 4 includes at least two oil collection tanks 41 connected in parallel.

[0050] In this embodiment, the parallel connection of the oil collection tanks 41 ensures the efficient and stable operation of the device through redundancy, flexible control and convenient maintenance, while also taking into account scalability and space adaptability to ensure the efficient and stable operation of the device.

[0051] Furthermore, such as Figure 1 As shown, in order to stabilize the device pressure, reduce the fluctuating load of the vacuum pump 52, and extend the life of the vacuum pump 52, the vacuum assembly 5 includes a vacuum buffer tank 51 and a vacuum pump 52 connected in sequence; the vacuum pump 52 is connected to the vacuum buffer tank 51 at one end and to the water collection tank 80 at the other end through a water pipe 90.

[0052] In this embodiment, if the mixture (including water, oil and recycled materials) is directly extracted by the vacuum pump 52 during the mixture extraction process, the instantaneous gas volume may fluctuate drastically due to uneven evaporation rate of the mixture or changes in liquid level in the reactor 1. Therefore, the vacuum buffer tank 51 can absorb sudden changes in gas flow by providing a certain volume space, thus avoiding damage to the vacuum pump 52 due to frequent start-stop or sudden load changes. In addition, it can reduce the "surging" phenomenon of the vacuum pump 52 and reduce the risk of mechanical wear and motor overload.

[0053] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
