[0003] In the prior art, CN218993477U discloses a heat energy collection system for frying equipment. Although the above-mentioned prior art achieves the recovery and utilization of flue gas through the setting of a recovery hood, in actual use, in order to ensure the coverage area of ​​the flue gas recovery area, a large volume recovery hood is required. In order to ensure that the entire area is not missed, a large air volume is required to form a sufficient negative pressure field. The fan power is large and the energy consumption is relatively high, resulting in poor flue gas recovery effect in actual use. Furthermore, using a large fixed hood will also increase the floor space. In view of this, we propose a heat energy recovery device for frying equipment to solve the above problems.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A heat recovery device for frying equipment includes a frying equipment body 1. A movable pipe 2 is arranged between two vertical plates on both sides of the frying equipment body 1. A cavity 3 is opened inside the movable pipe 2. A through groove 4 is opened on the surface of the movable pipe 2, and the through groove 4 is connected to the cavity 3. At this time, the flue gas is circulated by the interface between the cavity 3 and the through groove 4. A sliding groove 5 is opened inside each of the two vertical plates on both sides of the frying equipment body 1. A sliding block 6 is slidably connected inside the sliding groove 5. A connecting rod 7 is rotatably sleeved inside each of the two sliding blocks 6. Fixed pipes 8 are fixedly connected to both ends of the movable pipe 2. Fixed flanges 9 are arranged between the two fixed pipes 8 and the two connecting rods 7. The interior of the left connecting rod 7 is hollow. The left fixed pipe 8 and the left connecting rod 7 are connected through the fixed flange 9. The fixed flange 9 makes it easy for the staff to disassemble and clean the movable pipe 2. The two connecting rods 7 rotatably pass through the interior of the two sliding blocks 6 respectively. A transmission component is arranged outside the two connecting rods 7. A recovery component is arranged on the left side of the frying equipment body 1.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the recycling assembly includes a first connecting pipe 11, a support plate 13 is fixedly connected to the outside of the first connecting pipe 11, the support plate 13 is fixedly connected to the frying equipment body 1, a second connecting pipe 10 is provided on the upper side of the first connecting pipe 11, a rotating flange 14 is provided between the second connecting pipe 10 and the left connecting rod 7, and the second connecting pipe 10 and the left connecting rod 7 are connected through the rotating flange 14.

[0030] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a flexible hose 12 is provided between the first connecting pipe 11 and the second connecting pipe 10. The first connecting pipe 11 and the second connecting pipe 10 are connected through the flexible hose 12. By connecting the first connecting pipe 11 to the external pump body, the negative pressure formed inside the pipe will draw the fumes generated by the frying equipment body 1 from the through groove 4 into the cavity 3, and then into the left fixed pipe 8 through the cavity 3. Subsequently, the fumes are drawn into the left connecting rod 7 through the cooperation of the left fixed pipe 8 and the left fixed flange 9, and then into the second connecting pipe 10 through the left connecting rod 7. Finally, the fumes enter the hose 12 and the first connecting pipe 11, thereby realizing the recovery of fumes.

[0031] In the above embodiments, the first connecting pipe 11 is also equipped with a grease filter, a heat exchanger, a steam-water separator, and a steam compressor. The grease filter removes grease and solid particles from the exhaust gas. The heat exchanger allows the pre-treated high-temperature exhaust gas to pass through, releasing heat and cooling down, causing the water vapor to condense into water. The steam-water separator allows the steam-water mixture to enter the separator, where the liquid water is separated by gravity. The exhaust gas is then recycled by the steam compressor. The steam can then be connected to an external steamer via an external pipe to replace or partially replace the original primary steam required, thereby greatly reducing the amount of live steam used by the steamer, significantly reducing energy consumption, and lowering production costs.

[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the transmission assembly includes a transmission gear 15, which is fixedly sleeved on the outside of the connecting rod 7. Toothed plates 16 are fixedly connected to both sides of the frying equipment body 1. The two toothed plates 16 are respectively meshed with the two transmission gears 15. Moving the sliding block 6 moves the connecting rod 7, which in turn moves the transmission gear 15. The movement of the transmission gear 15 and the engagement of the toothed plates 16 allow the connecting rod 7 to rotate. This rotation of the connecting rod 7 then rotates the fixed tube 8, which in turn rotates the moving tube 2. This allows for the collection of smoke from different angles, increasing the range of smoke collection and reducing the amount of smoke escaping.

[0033] Example 2

[0034] The heat recovery device of the frying equipment provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the second connecting pipe 10 is externally fixedly fitted with a lower protective cover 19 and an upper protective cover 20. The lower protective cover 19 and the upper protective cover 20 are detachably connected, which can be bolted or snap-fitted. The main purpose is to facilitate the disassembly of the upper protective cover 20, thereby facilitating the maintenance of the internal structure. The lower protective cover 19 and the upper protective cover 20 are fitted on the outside of the sliding block 6. Since the sliding block 6 is rectangular, when the lower protective cover 19 and the upper protective cover 20 move, they can drive the sliding block 6 to slide inside the sliding groove 5, thereby realizing the movement of the moving pipe 2.

[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, cylinders 17 are fixedly connected to both sides of the frying equipment body 1. The piston rods of the two cylinders 17 are fixedly connected to the two lower protective covers 19 respectively. Sliding rods 18 are fixedly connected to both sides of the frying equipment body 1. The two lower protective covers 19 are slidably sleeved on the outside of the two sliding rods 18 respectively. The setting of the sliding rods 18 effectively ensures the stability and smoothness of the sliding of the lower protective cover 19 and the upper protective cover 20.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, both lower protective covers 19 have recessed grooves 22 inside, and the two toothed plates 16 are located inside the two recessed grooves 22 respectively. The recessed grooves 22 effectively prevent interference between the lower protective cover 19 and the toothed plates 16 when they move. At the same time, the cooperation between the lower protective cover 19 and the upper protective cover 20 protects the transmission gear 15 and the toothed plates 16, effectively preventing external oil fumes from adhering to the surface of the transmission components, ensuring the smooth operation of the device, and reducing the maintenance frequency.

[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, pulleys 21 are embedded on both the upper and lower surfaces of the sliding block 6. The sliding block 6 contacts the inner wall of the sliding groove 5 through the pulleys 21. The setting of the pulleys 21 effectively improves the smoothness of the sliding block 6 sliding inside the sliding groove 5 and avoids jamming.

[0038] The heat recovery device for the frying equipment provided by this utility model is used as follows:

[0039] The controller activates the external device to create a negative pressure inside the first connecting pipe 11. At this time, the fumes generated by the frying equipment body 1 are drawn into the cavity 3 through the channel 4, and then into the left fixed pipe 8 through the cavity 3. Subsequently, the fumes are drawn into the left connecting rod 7 through the cooperation of the left fixed pipe 8 and the left fixed flange 9. The fumes then enter the second connecting pipe 10 through the left connecting rod 7, and then enter the hose 12 and the first connecting pipe 11, thereby realizing the recovery of fumes.

[0040] During heat recovery, the operator can activate cylinder 17. The movement of the piston rod of cylinder 17 moves the lower protective cover 19, which in turn moves the upper protective cover 20 synchronously. At this time, the lower protective cover 19 slides outside the sliding rod 18. The movement of the lower protective cover 19 and the upper protective cover 20 moves the sliding block 6 inside the sliding groove 5. The movement of the sliding block 6 moves the connecting rod 7, which in turn moves the transmission gear 15. The movement of the transmission gear 15 and the engagement of the toothed plate 16 enable the connecting rod 7 to rotate. The rotation of the connecting rod 7 drives the rotation of the fixed pipe 8, which in turn drives the rotation of the moving pipe 2. Ultimately, the moving pipe 2 can swing during its movement, thereby collecting flue gas from different angles, increasing the range of flue gas collection, reducing the amount of flue gas escaping, and improving heat recovery efficiency.
