The hot air becomes the drying medium, which is both a heat carrier and a moisture carrier. That is to say, noodle drying requires heat, and heat and moisture exchange is carried out by heat. Only after the wet noodles absorb heat can their own moisture vaporize and be discharged to achieve the purpose of drying. When the hot air is discharged from the workshop, the waste heat needs to be recovered to avoid waste of resources.

[0003] When the existing waste heat recovery device for a noodle workshop is in use, the waste heat recovery is not thorough.

[0028] In order to make the content of the present utility model easier to be clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0029] Embodiment 1

[0030] As Figures 1 to 4 shown, a waste heat recovery device for a noodle drying workshop includes a box body 1. An intake pipe 2 is installed at one end of the box body 1, and an exhaust pipe 3 is installed at the other end of the box body 1. The intake pipe 2 is used to connect the exhaust gas pipeline of the noodle drying workshop, and the gas with a lower temperature flows out from the exhaust pipe 3 after heat exchange inside the box body 1.

[0031] A water tank 4 is fixedly installed inside the box body 1. A heat exchange pipe 5 is installed on the surface of the water tank 4. The heat exchange pipe 5 is wound around the surface of the water tank 4 in an S shape. One end of the heat exchange pipe 5 is connected to the intake pipe 2, and the other end of the heat exchange pipe 5 penetrates through a partition board 6. The partition board 6 is fixedly installed inside the box body 1. A water injection port 23 is installed at the upper end of the water tank 4, and a cover plate is installed at the upper end of the water injection port 23. Water can be added into the box body 1 through the water injection port 23. A water outlet 24 is installed at the lower end of the water tank 4, and a valve is installed at the water outlet 24. Water can be drained through the water outlet 24.

[0032] Specifically, in the noodle drying workshop, the air in the drying room needs to be heated to dry the noodles. A large amount of heat is accompanied by the discharge of the air in the drying room. The pipeline for discharging the hot air is connected to the intake pipe 2. The hot air enters the inside of the heat exchange pipe 5 and exchanges heat with the water inside the water tank 4. The temperature of the hot air decreases, and the temperature of the water inside the water tank 4 increases. The S-shaped winding of the heat exchange pipe 5 can increase the contact area with the water tank 4.

[0033] A long plate 21 is installed inside the heat exchange tube 5. There are multiple groups of long plates 21 symmetrically arranged. The included angle between the long plate 21 and the inner wall of the heat exchange tube 5 is 45 degrees. A short plate 22 is installed on one side of the long plate 21, and the long plate 21 is parallel to the short plate 22.

[0034] When high-temperature gas enters the inside of the heat exchange tube 5, part of the air flow flows between the two long plates 21 on both sides, and the other part of the air flow rushes to the angle between the long plate 21 and the heat exchange tube 5 and flows back, converging with the air flow between the two long plates 21, thereby slowing down the air flow. When there are short plates 22 inside the two long plates 21, the air flow will form a vortex in the two long plates 21 and the short plates 22, also slowing down the overall air flow, so that the high-temperature gas slowly flows through the water tank 4, making the heat exchange more sufficient.

[0035] The filter net 7 is slidably installed inside the box body 1. An insertion structure 8 is installed at the upper end of the filter net 7, and a slot structure 9 is installed on one side of the filter net 7. Inserting the insertion structure 8 into the slot structure 9 is convenient for fixing the filter net 7.

[0036] The slot structure 9 includes a housing 10. One side of the bottom end inside the housing 10 is installed with a first spring 11. The upper end of the first spring 11 is installed with an engagement block 12. A second spring 13 is installed on one side of the first spring 11. The rotating rod 14 is L-shaped. The vertex of the rotating rod 14 is rotatably connected to the inside of the housing 10. One end of the rotating rod 14 is located above the second spring 13. A clamping block 15 is installed at the other end of the rotating rod 14. The pressing plate 16 is located above one end of the rotating rod 14, and the pressing plate 16 can slide inside the upper side of the housing 10.

[0037] The insertion structure 8 includes a cross plate 17. The lower end of the cross plate 17 is fixedly installed at the upper end of the filter net 7. A handle 18 is installed at the upper end of the cross plate 17. It is convenient to pull up the cross plate 17 and the filter net 7 through the handle 18, facilitating the removal of the filter net 7 for cleaning. A support plate 19 is fixedly installed at one end of the cross plate 17. An insertion plate 20 is installed at the lower end of the support plate 19. The insertion plate 20 can be inserted into the inside of the housing 10. A card slot is opened at the lower part of the insertion plate 20. A clamping block 15 is installed at one end of the rotating rod 14, and the clamping block 15 is clamped in the card slot. The surface of the clamping block 15 is a smooth curved surface.

[0038] Specifically, when installing the filter net 7, insert the filter net 7 into the inside of the box body 1. At the same time, insert the insertion plate 20 into the inside of the housing 10. The bottom end of the insertion plate 20 moves downward and compresses the first spring 11, so that the clamping block 15 is inserted into the card slot to fix the insertion plate 20. The gas after heat exchange passes through the filter net 7 and then flows out through the air outlet pipe 3, avoiding gas pollution to the environment. When it is necessary to disassemble, press down the pressing plate 16. The lower end of the pressing plate 16 compresses the second spring 13 through the rotating rod 14. The rotating rod 14 rotates around the vertex, so as to drive the clamping block 15 at one end of the rotating rod 14 to disengage from the card slot. The first spring 11 is restored, giving an upward elastic force to the insertion plate 20, so that the filter net 7 can be conveniently taken out through the handle 18.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, it is described that the noodle workshop needs to use the air in the heating and drying chamber to dry the noodles. A large amount of heat is discharged along with the air exhausted from the drying chamber. The pipe for exhausting the hot air is connected to the intake pipe 2. The hot air enters the interior of the heat exchange pipe 5 and exchanges heat with the water inside the water tank 4. The temperature of the hot air decreases, and the temperature of the water inside the water tank 4 increases. When the high-temperature gas enters the interior of the heat exchange pipe 5, part of the air flow flows between the two long plates 21 on both sides, and another part of the air flow rushes towards the angle between the long plate 21 and the heat exchange pipe 5 and flows back, converging with the air flow between the two long plates 21 on both sides, thereby slowing down the air flow. When there are short plates 22 inside the two long plates 21, the air flow will form a vortex in the two long plates 21 and the short plates 22, also slowing down the overall air flow, so that the high-temperature gas slowly flows through the water tank 4, making the heat exchange more sufficient.

[0041] When installing the filter net 7, insert the filter net 7 into the interior of the box body 1. At the same time, insert the insertion plate 20 into the interior of the housing 10. The bottom end of the insertion plate 20 moves downward and compresses the first spring 11, so that the clamping block 15 is inserted into the card slot to fix the insertion plate 20. The gas after heat exchange passes through the filter net 7 and flows out through the air outlet pipe 3, avoiding gas pollution to the environment. When it needs to be disassembled, press down the pressing plate 16. The lower end of the pressing plate 16 compresses the second spring 13 through the rotating rod 14. The rotating rod 14 rotates around the vertex, so as to drive the clamping block 15 at one end of the rotating rod 14 to disengage from the card slot. The first spring 11 resumes its original state, giving an upward elastic force to the insertion plate 20, so that the filter net 7 can be conveniently taken out through the handle 18.

[0042] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
