Description

Technical Field

[0001] The invention relates to the technical field of return air, and in particular to a supply and return air duct of a waste heat recovery heat pump unit. Background Art

[0002] Because existing noodle processing manufacturers mostly use gas boilers and electric boilers in the process of drying noodles, a large amount of water vapor will be generated during the drying process of noodles, which needs to be discharged to the outside by dehumidification fans. This will cause a large amount of heat energy to be discharged from the drying room, resulting in a large heat loss and poor economic benefits. Our company uses the reverse Carnot principle of air source heat pump to recycle the heat brought out by dehumidification and send it back to the drying room for continued use. At the same time, the moisture in the dehumidified air is condensed into water after passing through the evaporator of the unit, and is discharged separately for recycling and reuse. It not only saves energy and protects the environment, but also reduces energy consumption. It brings great economic benefits to the enterprise and makes outstanding contributions to environmental protection:

[0003] The existing pipelines used for supply and return of heat pump units need to meet the needs of recovering condensed water for steam and hot air. Since the pipeline is in contact with not only hot air but also condensed water, it not only has high requirements on the hardness of the pipeline, but also on the material of the pipe body. The tolerance requirements of the pipe body material are relatively strict. The assembly process of the harder pipe body and the heat pump unit is also very important. The sealing of the pipe body needs to be ensured. The pipe body with better sealing can improve the utilization rate of heat recovery.

[0004] However, general pipelines and heat pump units are generally assembled using ordinary threaded connections, and ordinary rubber gaskets and rubber rings are generally used for sealing. The rubber rings will turn yellow and harden due to oxidation after long-term use. The yellowed and hardened rubber rings will break over time and be affected by the pressure inside the pipeline. At this time, the pipe connection port will leak, and the leaking pipeline will affect the transmission efficiency of thermal energy. Summary of the invention

The mass of the outer ring baffle plate 2 7 is greater than the mass of the outer ring baffle plate 1 6, so the hollow holes 31 opened on the side wall of the outer ring baffle plate 2 7 are used to drip the condensed water into the inner side of the first fixed block 10, which plays a guiding role.

The bottom end of one side of the linkage rod 22 is fixedly connected with a limiting rod 26. One end of the limiting rod 26 away from the linkage rod 22 is clamped with the inner side of the slot 3 28. A special-shaped rod 24 is provided at one end of the linkage rod 22. The inner side is clamped with one end of the fixing hook 25. In this embodiment, the raised ball 14 fixedly connected on the side wall of the card 13 passes through the inner side of the shrinkage groove 18 and is clamped with the fixing hole 21 inside the receiving ring 15. The fixing hook 25 connected at one end of the shrinkage groove 18 is clamped with one end of the special-shaped rod 24. When clamped, the overall inclination angle of the linkage rod 22 is driven to change. When the inclination angle of the linkage rod 22 changes, the bottom end of the linkage rod 22 is clamped on one side of the fixing hole 21, and the top end of the limiting rod 26 connected to the other end of the linkage rod 22 is clamped on the inner side of the clamping groove three 28, which limits the inclination angle of the linkage rod 22.

[0032] A connecting ring 19 is fixedly connected to the inner wall of the rubber ring 2 at equal intervals, a second card slot 17 is opened in the middle position of the inner side of the connecting ring 19, and a contraction groove 18 that cooperates with the protruding ball 14 is opened at equal intervals on the inner wall of the connecting ring 19, and a fixing hook 25 is fixedly connected to one end of the contraction groove 18. A through groove 29 is horizontally arranged on the inner side of the connecting ring 19, and the inner side of the through groove 29 is slidably connected to the inner wall of the card 13. In this embodiment, the aluminum alloy splicing tube 11 is spliced ​​on the top of the aluminum alloy tube body 1, and the aluminum alloy splicing tube 11 is spliced ​​on the top of the aluminum alloy tube body 1. The fixing ring 12 is inserted into the inner side of the aluminum alloy tube body 1. After being inserted into the inner side of the aluminum alloy tube body 1, the aluminum alloy splicing tube 11 is rotated. During the rotation, the aluminum alloy splicing tube 11 drives the fixing ring 12 to rotate. The fixing ring 12 rotates on the inner side of the aluminum alloy tube body 1. First, align the card 13 on one side of the fixing ring 12 with the card slot 2 17. The rotation of the fixing ring 12 drives the card 13 to slide on the inner side of the connecting ring 19. The card 13 penetrates the through groove 29 set on the inner side of the connecting ring 19 to complete the assembly.

[0033] Working principle: First, the tube bodies are spliced ​​together, the aluminum alloy splicing tube 11 is spliced ​​on the top of the aluminum alloy tube body 1, and the fixing ring 12 is inserted into the inner side of the aluminum alloy tube body 1. After inserting into the inner side of the aluminum alloy tube body 1, the aluminum alloy splicing tube 11 is rotated. The aluminum alloy splicing tube 11 drives the fixing ring 12 to rotate during the rotation process. The fixing ring 12 rotates on the inner side of the aluminum alloy tube body 1. First, align the card 13 on one side of the fixing ring 12 with the card slot 17. The card 13 is driven to slide on the inner side of the connecting ring 19 by the rotation of the fixing ring 12. The card 13 penetrates the inside of the through groove 29 set on the inner side of the connecting ring 19. When the card 13 rotates inside the through groove 29, the raised ball 14 fixedly connected on the side wall of the card 13 penetrates the shrinkage groove The inner side of 18 is clamped with the fixing hole 21 inside the receiving ring 15, and the fixing hook 25 connected to one end of the shrinkage groove 18 is clamped with one end of the special-shaped rod 24. When clamped, the overall inclination angle of the linkage rod 22 is driven to change. When the inclination angle of the linkage rod 22 changes, the bottom end of the linkage rod 22 is clamped on one side of the fixing hole 21, and the top end of the limiting rod 26 connected to the other end of the linkage rod 22 is clamped on the inner side of the clamping groove 28, which limits the inclination angle of the linkage rod 22, and completes the fixation of the shrinkage groove 18 on the inner side wall of the receiving ring 15. After the inner side wall of the receiving ring 15 is fixed, the rubber ring 2 attached to the inner side of the receiving ring 15 and the inner side of the aluminum alloy tube body 1 are indirectly fixed, which solves the problem of fixing the sealing position of the rubber ring 2.

[0034] After the fixation is completed, the main body of the aluminum alloy spliced ​​tube 11 is conducted with hot air, and the hot air enters the inner side of the aluminum alloy tube body 1 and the aluminum alloy spliced ​​tube 11 in turn. After entering the inner side of the aluminum alloy tube body 1 and the aluminum alloy spliced ​​tube 11 in turn, since the hot air will go to the top of the pipe, the connecting disc 9 is driven to rotate through the transmission of wind force, and the rotation of the connecting disc 9 drives the bolt blade 901 to rotate to realize the conduction of hot air, and at the same time, the condensed liquid falls into the inner side of the guide groove 1001 at the top of the first fixed block 10, and the water vapor will adhere to the bolt blade 901. The water vapor will be affected by the centrifugal force and adhere to one side of the outer ring baffle 1 6 and the outer ring baffle 2 7. The mass of the outer ring baffle 2 7 is greater than the mass of the outer ring baffle 1 6, so the hollow hole 31 opened on the side wall of the outer ring baffle 2 7 is used to drip the condensed water into the inner side of the first fixed block 10, which plays a guiding role and can position the condensed water for output.
