Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery equipment technology, and in particular to a heat recovery device. Background Technology

[0002] In industrial production, heat treatment equipment generates a significant amount of heat during operation, which is typically released directly into the surrounding environment, leading to substantial energy waste. In traditional heat treatment workshops without dedicated heat recovery systems, high-temperature exhaust gases are directly discharged into the atmosphere. On one hand, this results in a large loss of thermal energy, increasing energy costs for businesses. On the other hand, the emission of high-temperature exhaust gases significantly raises the workshop temperature, deteriorating the working environment for employees.

[0003] While some heat recovery devices exist on the market, the insulation performance of the heat transfer pipes in some devices is poor, resulting in significant heat loss during heat transfer and low recovery efficiency. Furthermore, these devices cannot be flexibly adjusted according to actual operating conditions, making it difficult to effectively control the operating costs of the entire heat recovery system. In addition, existing devices exhibit poor adaptability when matched with different types and specifications of heat treatment equipment and heat-consuming equipment, failing to meet diverse industrial production needs. Utility Model Content

[0030] like Figures 1 to 3As shown, the preferred embodiment of this utility model provides a heat recovery device for recovering and recycling heat generated by heat treatment equipment. It includes a heat-conducting pipe assembly 1 for collecting heat generated by the heat treatment equipment, a fan assembly 2 connected to the heat-conducting pipe assembly 1, and an exhaust assembly 3 located at the outlet of the heat-conducting pipe assembly 1. The fan assembly 2 generates airflow within the heat-conducting pipe assembly 1 and drives the airflow through the assembly, allowing it to be heated by the heat collected within the assembly. The exhaust assembly 3 provides the airflow generated by the fan assembly 2 and heated by the heat collected in the heat-conducting pipe assembly 1 to heat-using equipment that requires heat recycling. By designing a reasonable heat-conducting pipe assembly 1, fan assembly 2, and exhaust assembly 3, the heat generated by the heat treatment equipment is effectively collected and transferred to heat-using equipment that requires heat recycling, such as for heating air or liquid required in other process steps, or for preheating workpieces to be processed. This not only enables energy recovery and reuse, reducing energy consumption and production costs for enterprises, but also improves the workshop environment, reduces thermal pollution and pollutant emissions to the atmosphere, and has significant economic, environmental, and social benefits.

[0031] Specifically, the heat-conducting pipe assembly 1 is connected to the heat treatment equipment on one hand to collect the heat generated by the equipment; on the other hand, it is connected to the fan assembly 2, allowing the airflow generated by the fan assembly 2 to flow inside it, thereby achieving heat transfer; and its outlet is also connected to the exhaust assembly 3, facilitating the delivery of the heated airflow to the exhaust assembly 3. Its internal space provides a flow channel for the airflow, allowing the airflow generated by the fan assembly 2 to flow within it. During the flow, the airflow can fully absorb the heat collected by the heat-conducting pipe assembly 1, realizing the transfer of heat from the pipe to the airflow, thereby transferring heat in the form of airflow carrying it.

[0032] The fan assembly 2 provides airflow to the interior of the heat-conducting pipe assembly 1, driving the airflow to flow within the heat-conducting pipe assembly 1, thereby ensuring sufficient contact between the airflow and the heat collected in the heat-conducting pipe assembly 1 to complete the heating process. The exhaust assembly 3 is installed at the outlet of the heat-conducting pipe assembly 1, receives the airflow heated by the heat collected in the heat-conducting pipe assembly 1, and then provides the airflow to the heat-using equipment that needs to recycle the heat, thus realizing the recycling of heat.

[0033] In this embodiment, the heat-conducting pipe assembly 1 includes multiple manifolds 11 and a heat-conducting main pipe 12. The multiple manifolds 11 are used to collect heat from multiple areas of the heat treatment equipment, and the heat-conducting main pipe 12 is simultaneously connected to the multiple manifolds 11. Since the heat generated in different areas of the heat treatment equipment may vary during operation and the heat distribution is relatively dispersed, the multiple manifolds 11 can collect heat from different areas respectively, ensuring that the heat generated in each area can be effectively collected. The heat-conducting main pipe 12 serves as the converging channel for the multiple manifolds 11, integrating the heat collected and converged by each manifold 11, enabling the heat to be transmitted at a large flow rate and in a relatively stable state, providing a sufficient heat source for subsequent heat and airflow heat exchange.

[0034] Specifically, the piping assembly also includes a plurality of support frames 13 connected to the heat conduction main pipe 12 for supporting the heat conduction main pipe 12, and the plurality of support frames 13 are alternately arranged with the plurality of manifolds 11.

[0035] In this embodiment, the fan assembly 2 includes a fan 21 for generating airflow, a frequency converter for adjusting the rotational speed of the fan 21, and a connection structure 22 for connecting the fan 21 to the heat transfer pipe 12. The fan 21 drives an impeller to rotate via a motor, causing air or other gases to flow, providing a continuous and stable airflow for the entire heat recovery system, allowing heat to be transported and utilized along with the airflow. The frequency converter adjusts the rotational speed of the fan 21, achieving energy saving and precise control; the connection structure 22 prevents airflow leakage between the fan 21 and the heat transfer pipe 12, avoiding airflow loss and reduced heat transfer efficiency due to leakage.

[0036] Specifically, the connection structure 22 includes a flexible joint 221 and a clamp 222. The flexible joint 221 connects the fan 21 and the heat transfer main pipe 12. The clamp 222 is installed on the flexible joint 221 to prevent heat dissipation from the flexible joint 221. The clamp 222 is fitted onto the flexible joint 221 and is tightly connected to the flexible joint 221 by means of clamping and fixing, thus constraining and protecting the flexible joint 221.

[0037] In this embodiment, the heat-conducting pipe assembly 1 further includes a conveying pipe 14 for conveying airflow, installed between the fan 21 and the exhaust assembly 3. The conveying pipe 14 is a conveying channel for the airflow that has been driven by the fan 21 and heated by the heat-conducting pipe assembly 1.

[0038] Specifically, the exhaust assembly 3 includes an air intake structure 31 and a flow delivery unit. The air intake structure 31 is connected to the delivery pipe 14 and is responsible for receiving the heated airflow delivered from the delivery pipe 14. The flow regulation unit is located between the fan 21 and the air intake structure 31 and is used to control the flow rate of the heated airflow.

[0039] Specifically, the air intake structure 31 includes an air intake chamber 311 connected to the delivery pipe 14 for accommodating the heated airflow, a rectifier plate 312 for guiding the flow direction of the heated airflow, an acceleration channel 313 for accelerating the heated airflow, and an air outlet 314 for discharging the heated airflow. The inlet of the air intake chamber 311 is directly connected to the outlet of the delivery pipe 14. The heated airflow in the delivery pipe 14 first enters the air intake chamber 311, which can act as a buffer space to buffer and stabilize the flow velocity and pressure of the airflow to a certain extent. The rectifier plate 312 is located inside the air intake chamber 311, usually on the airflow channel of the air intake chamber 311, and guides the flow direction of the heated airflow entering the air intake chamber 311, making the flow of the airflow in the air intake chamber 311 more orderly and stable. The inlet of the acceleration channel 313 is connected to the outlet of the air intake chamber 311 and adopts a tapering pipe structure. When the airflow passes through the acceleration channel 313, its flow velocity increases as the cross-sectional area of ​​the channel decreases.

[0040] In this embodiment, the heat recovery device also includes a drying device connected to the exhaust assembly 3 for using the heated airflow discharged from the exhaust assembly 3 to dry the target that needs to be dried.

[0041] In this embodiment, the heat recovery device further includes heat insulation components installed on the exterior of the heat conduction pipe assembly 1, the exhaust assembly 3, and the fan assembly 2. Specifically, the heat insulation components can be heat insulation materials such as glass wool or vacuum insulation panels.

[0042] This utility model provides a heat recovery device for recycling heat generated by heat treatment equipment. It includes a heat-conducting pipe assembly 1 for collecting heat generated by the heat treatment equipment, a fan assembly 2 connected to the heat-conducting pipe assembly 1, and an exhaust assembly 3 located at the outlet of the heat-conducting pipe assembly 1. The fan assembly 2 generates airflow within the heat-conducting pipe assembly 1 and drives the airflow through the assembly, allowing it to be heated by the heat collected within the assembly. The exhaust assembly 3 provides the airflow generated by the fan assembly 2 and heated by the heat collected in the heat-conducting pipe assembly 1 to heat-using equipment that requires heat recycling. By rationally designing the heat-conducting pipe assembly 1, fan assembly 2, and exhaust assembly 3, the heat generated by the heat treatment equipment is effectively collected and transferred to heat-using equipment that requires heat recycling, such as for heating air or liquid required in other processes, or for preheating workpieces to be processed. This not only enables energy recovery and reuse, reducing energy consumption and production costs for enterprises, but also improves the workshop environment, reduces thermal pollution and pollutant emissions to the atmosphere, and has significant economic, environmental, and social benefits.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
