Description

Technical Field

[0001] This utility model belongs to the field of residual liquid treatment technology, specifically relating to a collection tank for residual liquid from F142b pyrolysis preparation of VDF. Background Technology

[0002] In the process of producing VDF (vinylidene fluoride) from F142b by cracking, the residual liquid collection system is a crucial link in ensuring production safety and resource utilization. Modern cracking units employ multi-stage condensation separation technology, achieving efficient separation of VDF monomers and byproducts from the cracked gas through precise control of temperature and pressure parameters. The residual liquid mainly contains incompletely cracked F142b, HF byproducts, and high-boiling-point organic compounds, and its collection and treatment directly affect product purity and the stability of unit operation.

[0003] In the existing technology, the collection tank for VDF residue from F142b pyrolysis lacks effective filtration during the processing. This results in solid impurities such as polymer residues and catalyst particles generated during the pyrolysis process directly entering the collection system. These impurities not only contaminate valuable reusable components but also cause tray blockage during subsequent distillation, affecting separation efficiency. At the same time, viscous polymer residues and corrosive fluoride crystals easily accumulate on the tank walls and bottom, which are usually cleaned manually. This process is time-consuming, labor-intensive, inconvenient, and has low cleaning efficiency.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a collection tank for VDF residue from F142b pyrolysis to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A VDF residue collection tank prepared by Fb pyrolysis includes a processing tank. One end of the processing tank is fixed with a feed pipe communicating with the inside of the processing tank. The inside of the processing tank is provided with a frame plate. Multiple sides of the frame plate are fixed with densely distributed bristles that contact the inner sidewall of the processing tank. The end of the processing tank away from the feed pipe is provided with a discharge port. A filter plate is provided in the discharge port. A servo motor is fixed on the outer sidewall of the processing tank. The inside of the processing tank is provided with an adjustment component that drives the frame plate to reciprocate.

[0008] Preferably, the adjustment assembly includes a lead screw disposed inside the processing tank and arranged along the length of the processing tank. The two ends of the lead screw are rotatably connected to the side wall of the processing tank. The output end of the servo motor is fixed to one end of the lead screw. A connecting rod is fixed on the side of the frame plate, and a lead screw nut that is threadedly engaged with the lead screw is fixed to the end of the connecting rod.

[0009] Preferably, a guide rod is fixed to the bottom end of the lead screw nut, and a guide groove is provided on the inner side wall of the bottom end of the processing groove to slide and adapt to the guide rod.

[0010] Preferably, the end of the processing tank has two symmetrically distributed slots, and the filter plate is slidably inserted into the slots.

[0011] Preferably, the top of the processing tank is an opening, and a cover plate is hinged to the top opening of the processing tank.

[0012] Preferably, a lifting rod is fixed to the side of the filter plate, and a rubber sleeve is fitted onto the surface of the lifting rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The residual liquid is filtered through a filter plate to remove solid impurities, effectively reducing the solid impurity content in the waste liquid. This significantly reduces the solid content, meeting environmental emission standards and creating conditions for potential waste liquid reuse. Simultaneously, the collected solid impurities can be centrally processed, achieving waste classification management and improving resource utilization.

[0015] 2. After prolonged use, a significant amount of solid impurities accumulate on the sides of the filter plates, affecting flow efficiency. The servo motor is then activated, driving the adjustment component to move the frame plate back and forth within the treatment tank. This allows the brushes on the side of the frame plate to thoroughly clean the inner walls of the tank, eliminating the need for manual cleaning. This significantly reduces cleaning workload, saves manpower, improves cleaning efficiency, and provides a more comprehensive and effective cleaning. Attached Figure Description

[0026] See attached document Figure 1-5A VDF residue collection tank for F142b pyrolysis includes a treatment tank 3. A feed pipe 5, communicating with the interior of the treatment tank 3, is fixed to one end of the treatment tank 3. A frame plate 8 is installed inside the treatment tank 3. Multiple sides of the frame plate 8 are fixed with densely distributed bristles 9 that contact the inner wall of the treatment tank 3. An outlet 6 is opened at the end of the treatment tank 3 away from the feed pipe 5. A filter plate 7 is installed inside the outlet 6. A servo motor 4 is fixed to the outer wall of the treatment tank 3. An adjustment component 1, which drives the frame plate 8 to reciprocate, is installed inside the treatment tank 3. In use, the production residue is input into the treatment tank 3 through the feed pipe 5 and filtered by the filter plate 7. The filter plate 7 removes solid impurities from the residue, effectively reducing the solid impurity content in the waste liquid. The treated waste liquid has a significantly reduced solid content, meeting environmental emission standards and creating conditions for potential waste liquid reuse. Meanwhile, the solid impurities collected by filtration can be centrally processed, realizing the classified management of waste and improving resource utilization. After the treatment tank 3 has been used for a long time, a lot of solid impurities will adhere and accumulate on the side of the filter plate 7, affecting the flow efficiency. The servo motor 4 is started to work, and the output end of the servo motor 4 drives the adjustment component 1 to work. In turn, the adjustment component 1 drives the frame plate 8 to move back and forth inside the treatment tank 3. The brush bristles 9 on the side of the frame plate 8 thoroughly clean the inner wall of the treatment tank 3, eliminating the need for manual cleaning of the inside of the treatment tank 3, effectively reducing the cleaning workload, saving manpower, improving cleaning efficiency, and making the cleaning more comprehensive and effective.

[0027] Further as Figure 3 and Figure 5 As shown, it is worth noting that the adjustment component 1 includes a lead screw 104 disposed inside the processing tank 3 and arranged along the length of the processing tank 3. The two ends of the lead screw 104 are rotatably connected to the side wall of the processing tank 3. The output end of the servo motor 4 is fixed to one end of the lead screw 104. A connecting rod 101 is fixed on the side of the frame plate 8, and a lead screw nut 102 that is threadedly engaged with the lead screw 104 is fixed to the end of the connecting rod 101. When the processing tank 3 has been used for a long time, a lot of solid impurities adhere to and accumulate on the side of the filter plate 7, affecting the flow efficiency. The servo motor 4 is started to work, and the output end of the servo motor 4 drives the lead screw 104 to rotate back and forth. Thus, the lead screw 104 and the lead screw nut 102 work together to drive the frame plate 8 to move back and forth inside the processing tank 3. Thus, the brush bristles 9 on the side of the frame plate 8 thoroughly clean the inner side wall of the processing tank 3, eliminating the need for manual cleaning of the inside of the processing tank 3, effectively reducing the amount of cleaning work, saving manpower, improving cleaning efficiency, and making the cleaning more comprehensive and effective.

[0028] Further as Figure 3 and Figure 5As shown, it is worth noting that a guide rod 103 is fixed to the bottom end of the lead screw nut 102, and a guide groove is provided on the inner side wall of the bottom end of the processing groove 3 to slide and adapt to the guide rod 103. When the lead screw nut 102 moves, the lead screw nut 102 drives the guide rod 103 to slide in the guide groove. Thus, the lead screw nut 102 and the guide groove cooperate to guide and limit the movement of the frame plate 8, thereby improving the stability of the movement adjustment of the frame plate 8.

[0029] Further as Figure 4 As shown, it is worth noting that two symmetrically distributed slots 10 are provided at the end of the treatment tank 3, and the filter plate 7 is slidably inserted into the slot 10. In actual operation, the filter plate 7 can be easily pulled out through the slot 10, which is convenient for operation.

[0030] This solution has the following working process: Production residue is fed into the treatment tank 3 through the feed pipe 5, and filtered by the filter plate 7. The filter plate 7 removes solid impurities from the residue, effectively reducing the content of solid impurities in the waste liquid. The solid content of the treated waste liquid is significantly reduced, which not only meets the environmental emission standards, but also creates conditions for possible subsequent waste liquid reuse. After the treatment tank 3 has been used for a long time, a lot of solid impurities will accumulate on the side of the filter plate 7, affecting the flow efficiency. The servo motor 4 is started to work. The output end of the servo motor 4 drives the lead screw 104 to rotate in both directions. The lead screw 104 and the lead screw nut 102 work together to drive the frame plate 8 to move back and forth inside the treatment tank 3. The brush bristles 9 on the side of the frame plate 8 thoroughly clean the inner wall of the treatment tank 3, eliminating the need for manual cleaning of the inside of the treatment tank 3.

[0031] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the top of the processing tank 3 is set as an opening, and a cover plate 2 is hinged to the top opening of the processing tank 3; in actual operation, by opening the cover plate 2, it is convenient to maintain the inside of the processing tank 3 and to facilitate operation.

[0032] Further as Figure 3 As shown, it is worth noting that a lifting rod is fixed on the side of the filter plate 7, and a rubber sleeve is fitted on the surface of the lifting rod; in actual operation, the filter plate 7 can be easily pulled by the lifting rod, which facilitates operation.

[0033] In summary: The filter plate 7 filters the residual liquid, removing solid impurities and effectively reducing the solid impurity content in the waste liquid. The significantly reduced solid content of the treated waste liquid meets environmental emission standards and creates conditions for potential waste liquid reuse. Simultaneously, the collected solid impurities can be centrally processed, achieving waste classification management and improving resource utilization. After prolonged use, a significant amount of solid impurities accumulates on the sides of the filter plate 7, affecting flow efficiency. Activating the servo motor 4 activates the adjustment component 1, which in turn moves the frame plate 8 reciprocating within the treatment tank 3. This allows the brush bristles 9 on the side of the frame plate 8 to thoroughly clean the inner walls of the treatment tank 3, eliminating the need for manual cleaning, effectively reducing workload, saving manpower, improving cleaning efficiency, and achieving a more comprehensive and effective cleaning.

[0034] The servo motor 4 can be purchased from the market. The servo motor 4 is equipped with a power supply. It is a mature technology in this field and has been fully disclosed. Therefore, it will not be described again in the specification.
