Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology, specifically an energy-saving waste heat recovery system for heat treatment. Background Technology

[0002] Heat treatment is one of the important processes in mechanical manufacturing. Generally, heat treatment does not change the shape and overall chemical composition of the workpiece, but rather imparts or improves the performance of the workpiece by changing the internal microstructure or the chemical composition of the surface of the workpiece.

[0003] In existing technologies, after the heat treatment process is completed, the heat treatment device cools down naturally, resulting in a significant loss of heat resources and a waste of thermal resources. Furthermore, the heat treatment process generates a large amount of smoke and dust, which negatively impacts the working environment and worker comfort. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an energy-saving waste heat recovery system for heat treatment, which has the advantages of high waste heat recovery rate and high dust removal rate, thus solving the problems mentioned in the background technology.

A first conveying pipe is fixedly installed on one side of the heat treatment device, a fan is fixedly installed on one side of the first conveying pipe, a filter shell is fixedly installed on one side of the fan, multiple filter mechanisms are snapped onto the upper side of the front end face of the filter shell, a collection mechanism is snapped onto the lower side of the front end face of the filter shell, guide blocks are fixedly installed on the inner walls of both the front and rear sides of the filter shell, a second conveying pipe is fixedly installed on one side of the filter shell, a heat exchange box is fixedly installed on one side of the second conveying pipe, a heat exchange mechanism is fixedly installed on one side of the heat exchange box, a waste heat recovery shell is fixedly installed on one side of the heat exchange mechanism, a waste heat recovery device is fixedly installed inside the waste heat recovery shell, and a third conveying pipe is fixedly installed between the heat treatment device and the heat exchange box.

[0006] As a preferred embodiment of the present invention, the filtration mechanism includes a housing, and a filter screen is fixedly installed inside the housing.

[0007] As a preferred embodiment of this utility model, a sealing ring is fixedly installed on the front end face of the device housing, and a handle is fixedly installed on the front end face of the device housing.

[0008] As a preferred embodiment of this utility model, the heat exchange mechanism includes a heat exchange rod, an insulating shell is fixedly installed on the outside of the heat exchange rod, a first heat exchange plate is fixedly installed on one side of the heat exchange rod, and a second heat exchange plate is fixedly installed on the other side of the heat exchange rod.

[0009] As a preferred embodiment of this utility model, a plurality of heat collection plates are fixedly installed on one side of the first heat exchange plate, and a plurality of heat dissipation plates are fixedly installed on one side of the second heat exchange plate.

[0010] As a preferred embodiment of this utility model, the collection mechanism includes a collection box, and a second handle is fixedly installed on the front end of the collection box.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This energy-saving waste heat recovery system uses a filtration mechanism to filter the high-temperature air during air exchange between the heat treatment unit and the heat exchange box, thereby removing dust mixed in with the high-temperature air. The cleaned dust will accumulate on the surface of the filter screen. After reaching a certain level, the dust will be collected inside the collection mechanism under the action of gravity through the guide block. After the waste heat recovery is completed, the filtration mechanism and the collection mechanism can be removed through the first handle and the second handle to clean the dust uniformly, so as to facilitate the next waste heat recovery operation. This can prevent dust from spreading and affecting the working environment and working comfort.

[0012] 2. This energy-saving waste heat recovery system uses a fan to transport hot air from inside the heat treatment device to the heat exchange box via the first and second conveying pipes. The heat of the high-temperature air is then absorbed by the heat collection plates and transferred to the waste heat recovery shell through the first heat exchange plate, heat exchange rod, second heat exchange plate, and heat dissipation plate. Thus, the waste heat recovery device completes the heat recovery. The air, after its heat has been absorbed by the heat collection plates, returns to the heat treatment device through the third conveying pipe to reabsorb heat and is then driven by the fan to continue heat transfer. This allows for more comprehensive and efficient recovery of waste heat. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 An energy-saving waste heat recovery system for heat treatment includes a heat treatment device 1. A first conveying pipe 2 is fixedly installed on one side of the heat treatment device 1. A fan 3 is fixedly installed on one side of the first conveying pipe 2. A filter shell 4 is fixedly installed on one side of the fan 3. Multiple filter mechanisms 5 are snapped onto the upper side of the front end face of the filter shell 4. A collection mechanism 10 is snapped onto the lower side of the front end face of the filter shell 4. Guide blocks 13 are fixedly installed on both the front and rear inner walls of the filter shell 4. A second conveying pipe 6 is fixedly installed on one side of the filter shell 4. A heat exchange box 9 is fixedly installed on one side of the second conveying pipe 6. A heat exchange mechanism 8 is fixedly installed on one side of the heat exchange box 9. A waste heat recovery shell 7 is fixedly installed on one side of the heat exchange mechanism 8. A waste heat recovery device 12 is fixedly installed inside the waste heat recovery shell 7. A third conveying pipe 11 is fixedly installed between the heat treatment device 1 and the heat exchange box 9. In the above structure, the high-temperature air in the heat treatment device 1 is transported to the heat exchange box 9 by the fan 3 in conjunction with the first conveying pipe 2 and the second conveying pipe 6. During the transport process, the high-temperature air passes through the inner wall of the filter shell 4, and is filtered out by the filter mechanism 5 to remove dust and other impurities mixed in with the high-temperature air. After the dust accumulates on the surface of the filter mechanism 5 to a certain extent, it will be collected by the guide block 13 under the action of gravity. This avoids dust pollution of the working environment and also prevents dust from entering the heat exchange box 9 and affecting the heat exchange efficiency of the heat exchange mechanism 8. The high-temperature air entering the heat exchange box 9 will have its heat transferred by the heat exchange mechanism 8 to the waste heat recovery shell 7, and then the waste heat will be recovered by the waste heat recovery device 12. After losing heat, the high-temperature air in the heat exchange box 9 will re-enter the heat treatment device 1 through the third conveying pipe 11, reabsorb heat, and circulate repeatedly under the drive of the fan 3. This makes the heat absorption in the heat treatment device 1 more thorough, and thus the waste heat recovery more thorough and efficient.

[0017] In a preferred embodiment, the filtering mechanism 5 includes a device housing 501, a filter screen 502 fixedly installed inside the device housing 501, a sealing ring 503 fixedly installed on the front end face of the device housing 501, and a first handle 504 fixedly installed on the front end face of the device housing 501. In the above structure, the filter mechanism 5 is snapped into the filter housing 4 through the device housing 501, and uses the filter screen 502 to filter out dust in the air. The sealing ring 503 can prevent high-temperature air from leaking out from the gap between the filter mechanism 5 and the filter housing 4, causing heat loss and dust to scatter. After the waste heat recovery is completed, the filter mechanism 5 can be taken out through the first handle 504 for cleaning, so as to ensure that the filter mechanism 5 can play a role in the next waste heat recovery.

[0018] In a preferred embodiment, the heat exchange mechanism 8 includes a heat exchange rod 801, an insulating shell 802 is fixedly installed on the outside of the heat exchange rod 801, a first heat exchange plate 803 is fixedly installed on one side of the heat exchange rod 801, a second heat exchange plate 805 is fixedly installed on the other side of the heat exchange rod 801, a plurality of heat collection plates 804 are fixedly installed on one side of the first heat exchange plate 803, and a plurality of heat dissipation plates 806 are fixedly installed on one side of the second heat exchange plate 805. In the above structure, by setting multiple heat collection plates 804, the contact area between the heat exchange mechanism 8 and the high-temperature air is increased, thereby increasing the heat exchange efficiency. The heat absorbed by the heat collection plates 804 is transferred to the interior of the waste heat recovery shell 7 through the first heat exchange plate 803, the heat exchange rod 801, the second heat exchange plate 805 and multiple heat dissipation plates 806, and is recovered by the waste heat recovery device 12. The heat insulation shell 802 is wrapped around the outside of the heat exchange rod 801, which can reduce the heat loss during the heat exchange process.

[0019] In a preferred embodiment, the collection mechanism 10 includes a collection box 1001, and a second handle 1002 is fixedly installed on the front end face of the collection box 1001; In the above structure, the dust filtered by the filter mechanism 5 will enter the collection box 1001 through the guide block 13 under the action of gravity. After the waste heat recovery is completed, the collection box 1001 can be taken out through the second handle 1002 for unified dust treatment.

[0020] Working principle: The high-temperature gas inside the heat treatment device 1 is transported to the heat exchange box 9 by the fan 3. The heat in the high-temperature air is then transferred to the waste heat recovery shell 7 by the heat exchange mechanism 8, and the waste heat is recovered by the waste heat recovery device 12. During the high-temperature air transport process, it passes through the filter mechanism 5, which filters out the dust mixed in with the air. After the dust accumulates to a certain level, it will be guided by gravity and enter the collection mechanism 10 through the guide block 13 to be collected. This not only avoids dust pollution of the working environment and affects the comfort of the workers, but also prevents a large amount of dust from entering the heat exchange box. Inside 9, the heat exchange efficiency of the heat exchange mechanism 8 is affected. After the waste heat collection is completed, the filter mechanism 5 and the collection mechanism 10 can be taken out and cleaned through the first handle 504 and the second handle 1002 to ensure the filtration effect of the filter mechanism 5 in the next waste heat recovery. The air that has absorbed the heat by the heat exchange mechanism 8 will return to the heat treatment device 1 through the third conveying pipe 11 and be carried out again by the fan 3. The cycle is repeated until the heat inside the heat treatment device 1 is completely absorbed. This can recover the heat inside the heat treatment device 1 more thoroughly and efficiently.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
