Description

Technical Field

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

[0002] In today's industrial production and daily life, the efficient utilization and recovery of energy is of paramount importance. Thermal energy, as a common form of energy, is widely present in various industrial production processes and some daily life scenarios. For example, the production processes in industries such as metallurgy, chemicals, and power generate large amounts of high-temperature waste gas, which contains abundant thermal energy. Effective recovery and utilization of this thermal energy can not only reduce energy consumption and production costs but also mitigate thermal pollution to the environment to some extent. However, in existing heat recovery devices, the gas often carries a large amount of moisture and impurities during its entry into the device. These moisture and impurities, once inside the heat exchange tubes, can cause rust and corrosion, reducing their service life. Simultaneously, impurities may clog the heat exchange tubes, affecting heat exchange efficiency and thus reducing the overall performance of the heat recovery device. Furthermore, most existing heat recovery devices are fixed installations, lacking flexibility. In some industrial production sites, adjustments to the production process or changes in equipment layout require relocation of the heat recovery device, making it difficult to conveniently and quickly move the device to a suitable location for use.

[0003] Therefore, it is necessary to provide a new heat recovery device to solve the above-mentioned technical problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a heat recovery device is provided to solve the above-mentioned problems.

[0005] The heat recovery device provided by this utility model includes: a box body; an air inlet pipe is provided on the top of one side of the box body, and an air outlet pipe is provided on the top of the other side; wherein, a filter cleaning component is provided inside the air inlet pipe, and the filter cleaning component can reduce the amount of moisture and impurities entering the heat exchange tube; a movable component is provided at the bottom of the box body, so as to flexibly adjust the position of the box body according to different usage scenarios and needs.

[0006] Preferably, the filter cleaning assembly includes a filter plate installed inside the air intake pipe, and a rotating head is rotatably connected to the side of the filter plate near the opening of the air intake pipe. Cleaning plates are connected to the top and bottom of the rotating head, and multiple cleaning brushes are connected to the side of the two cleaning plates near the filter plate.

[0007] Preferably, a sealing box is installed on the side of the filter plate away from the rotating head, and a driven bevel gear is rotatably connected to the inner wall of the sealing box. The driven bevel gear passes through the filter plate and is connected to the rotating head via a connecting shaft on the side near the filter plate. A driving bevel gear is rotatably connected to the inner bottom wall of the sealing box, and the bottom side of the driving bevel gear meshes with the driven bevel gear.

[0008] Preferably, a sealing tube is connected to the top of the sealing box, and the top of the sealing tube passes through the top of the air intake pipe and extends above the air intake pipe. A transmission rod is provided inside the sealing tube, and the bottom of the transmission rod passes through the top of the sealing box and is connected to the drive bevel gear. A first driving component for driving the transmission rod to rotate is installed at the top of the air intake pipe.

[0009] Preferably, the movable component includes support plates installed on both sides of the bottom of the housing, and two bidirectional screws are rotatably connected to the relatively close sides of the two support plates. Both outer ends of the two bidirectional screws are threaded with toothed plates, and the bottom of each toothed plate is meshed with a gear. Both sides of each gear are connected to the bottom of the housing through a connecting frame, and the bottom of each gear is connected with a movable wheel.

[0010] Preferably, one of the support plates has two spur gears rotatably connected to the side away from the other support plate. The outer sides of the two spur gears are connected by a synchronous belt drive. One side of each of the two spur gears passes through the support plate through a connecting rod and is connected to two bidirectional screws respectively. A second driving member for driving one of the bidirectional screws to rotate is installed on one side of the other support plate.

[0011] Compared with related technologies, the heat energy recovery device provided by this utility model has the following beneficial effects:

[0012] This invention, by installing a filter cleaning component inside the air inlet pipe, allows the filter plate to effectively intercept moisture and impurities in the gas, preventing them from entering the heat exchange tubes. This avoids damage to the heat exchange tubes due to moisture corrosion and impurity blockage, extends the service life of the heat exchange tubes, and ensures the normal operation of the heat energy recovery device. Simultaneously, the cleaning structure, composed of a rotating head, cleaning plate, cleaning brush, sealing box, driven bevel gear, driving bevel gear, sealing tube, transmission rod, and first driving component, can periodically clean the filter plate, preventing impurities from accumulating on it and ensuring that the filter plate maintains good filtration performance, thus improving the working efficiency and stability of the heat energy recovery device.

[0013] This invention enables the heat recovery device to be movable by incorporating a movable component at the bottom of the housing. A support plate provides stable support for the movable component. The bidirectional screw, toothed plate, gear, movable wheel, spur gear, and second drive component work together to easily extend and retract the movable wheel. When movement is needed, the movable wheel is extended, allowing the device to move flexibly to a suitable position; when movement is not required, the movable wheel is retracted, allowing the device to be placed stably. This allows the heat recovery device to flexibly adjust its position according to different usage scenarios and needs, such as process adjustments in industrial production sites or changes in the location of temporary work areas, improving the device's applicability and convenience.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] This utility model provides a heat recovery device, which includes: a housing 1; an air inlet pipe 11 is provided on the top of one side of the housing 1, and an air outlet pipe 12 is provided on the top of the other side; wherein, a filter cleaning component is provided inside the air inlet pipe 11, and the filter cleaning component can reduce the amount of moisture and impurities entering the heat exchange tube; a movable component is provided at the bottom of the housing 1 so as to flexibly adjust the position of the housing 1 according to different usage scenarios and needs.

[0021] It should be noted that: Box 1, as the main structure of the heat recovery device, provides installation and housing space for other components, making the entire device a relatively independent system and ensuring the orderly conduct of the heat recovery process within a specific space. The inlet pipe 11 is located at the top of one side of the box, guiding the heat-containing gas into the interior of box 1; it serves as the heat input channel. The outlet pipe 12 is located at the top of the other side of the box, discharging the treated gas from box 1; it serves as the output channel for the treated gas. The filter and cleaning assembly is located inside the inlet pipe 11, filtering the heat-containing gas before it enters the box and exchanges heat with the heat exchange tubes. The filter and cleaning assembly effectively intercepts moisture and impurities in the gas, preventing these substances from entering the heat exchange tubes. The movable assembly is located at the bottom of box 1, giving the heat recovery device mobility. Since different usage scenarios may have different requirements for the location of the heat recovery device, for example, in some industrial production sites, it may be necessary to move the heat recovery device flexibly according to the adjustment of the production process or the change of equipment layout; in some temporary work sites, it is also necessary to be able to move the device to a suitable location for use. The structure inside the box 1 is the same as the structure inside the box 1 in the patent with publication number CN222418650U, and will not be described further here.

[0022] In an embodiment of this utility model, the filter cleaning assembly includes a filter plate 2 installed inside the air intake pipe 11. A rotating head 21 is rotatably connected to the side of the filter plate 2 near the opening of the air intake pipe 11. Cleaning plates 22 are connected to the top and bottom of the rotating head 21. Multiple cleaning brushes 23 are connected to the side of each cleaning plate 22 near the filter plate 2. A sealing box 24 is installed on the side of the filter plate 2 away from the rotating head 21. A driven bevel gear 25 is rotatably connected to the inner wall of the sealing box 24. The driven bevel gear 25 passes through the filter plate 2 via a connecting shaft on the side near the filter plate 2. Connected to the rotating head 21, a driving bevel gear 26 is rotatably connected to the inner bottom wall of the sealing box 24. The bottom side of the driving bevel gear 26 meshes with the driven bevel gear 25. A sealing tube 27 is connected to the top of the sealing box 24, and the top of the sealing tube 27 passes through the top of the air intake pipe 11 and extends to the top of the air intake pipe 11. A transmission rod 28 is provided inside the sealing tube 27, and the bottom of the transmission rod 28 passes through the top of the sealing box 24 and is connected to the driving bevel gear 26. A first driving member for driving the transmission rod 28 to rotate is installed at the top of the air intake pipe 11.

[0023] It should be noted that the filter plate 2, installed inside the air inlet pipe 11, is the core component of the filter. When heat-containing gas enters through the air inlet pipe 11, it effectively intercepts moisture and impurities in the gas, preventing them from entering the heat exchange tubes inside the housing 1, protecting the heat exchange tubes from corrosion and blockage, and ensuring the normal operation and heat exchange efficiency of the device. To keep the filter plate 2 clean and prevent impurities from accumulating and affecting the filtration effect, a cleaning structure is provided. The rotating head 21 is rotatably connected to the side of the filter plate 2 near the opening of the air inlet pipe 11, serving as the rotation center of the cleaning structure. The top and bottom of the rotating head 21 are connected to the cleaning plate 22, and multiple cleaning brushes 23 are connected to the side of the cleaning plate 2 near the filter plate 2. When the rotating head 21 rotates, it drives the cleaning plate 22 and cleaning brushes 23 to make a circular motion around the surface of the filter plate 2. Through the friction between the bristles of the cleaning brushes 23 and the filter plate 2, the attached impurities are brushed off, keeping the filter plate 2 clean and maintaining good filtration performance. The rotation power of the rotating head 21 comes from the transmission system inside the sealed box 24. The sealing box 24 is installed on the side of the filter plate 2 away from the rotor 21, providing a sealed working environment for the transmission components, preventing gas leakage and the entry of external impurities, and protecting the transmission components. A driven bevel gear 25 is rotatably connected to the inner wall of the sealing box 24, and it is connected to the rotor 21 via a connecting shaft passing through the filter plate 2. A driving bevel gear 26 is rotatably connected to the bottom wall of the sealing box 24, with one bottom side meshing with the driven bevel gear 25. When the driving bevel gear 26 rotates, it drives the driven bevel gear 25 to rotate, thereby driving the rotor 21 to rotate. The power of the driving bevel gear 26 is transmitted by a transmission rod 28, which is located inside a sealing tube 27. The sealing tube 27 is connected to the top of the sealing box 24, and its top extends through the top of the air inlet pipe 11 and upwards. The bottom of the transmission rod 28 passes through the top of the sealing box 24 and connects to the active bevel gear 26. The first driving component installed on the top of the air inlet pipe 11 drives the transmission rod 28 to rotate. The first driving component is an electric motor. Through the transmission system, the cleaning brush 23 cleans the filter plate 2, ensuring that the filter cleaning assembly works continuously and effectively. The filter cleaning assembly can filter the gas before it enters the box and exchanges heat with the heat exchange tube. If a small amount of impurities enter the box 1, they are discharged through the impurity and moisture removal mechanism in the box 1. For details of the impurity and moisture removal mechanism, please refer to the patent content with publication number CN222418650U.

[0024] In an embodiment of this utility model, the moving component includes support plates 3 respectively installed on both sides of the bottom of the housing 1. Two bidirectional screws 31 are rotatably connected to the relatively close sides of the two support plates 3. The outer ends of the two bidirectional screws 31 are threaded with toothed plates 32. The bottom of each toothed plate 32 is meshed with a gear 33. The two sides of each gear 33 are connected to the bottom of the housing 1 through a connecting frame. The bottom of each gear 33 is connected with a moving wheel 34. Two spur gears 35 are rotatably connected to the side of one support plate 3 away from the other support plate 3. The outer sides of the two spur gears 35 are connected by a synchronous belt drive. One side of each of the two spur gears 35 passes through the support plate 3 through a connecting rod and is connected to the two bidirectional screws 31 respectively. A second driving member for driving one of the bidirectional screws 31 to rotate is installed on one side of the other support plate 3.

[0025] It should be noted that the movable component provides the device with flexible mobility, facilitating adjustments to the position of the housing 1 according to different usage scenarios and needs. Support plates 3 are installed on both sides of the bottom of the housing 1, providing support and a mounting base for other components, ensuring a stable connection between the movable component and the housing 1. Two bidirectional screws 31 are rotatably connected to the relatively close sides of the two support plates 3, with threaded connections to toothed plates 32 at their outer ends. When the bidirectional screws 31 rotate, their bidirectional thread characteristics cause the toothed plates 32 to move linearly in opposite directions. The bottom of the toothed plates 32 meshes with gears 33, which are connected to the bottom of the housing 1 via connecting brackets on both sides, with movable wheels 34 connected to their bottom. The linear movement of the toothed plates 32 drives the gears 33 to rotate, thereby causing the movable wheels 34 to extend or retract. When the movable wheels 34 extend and contact the ground, the housing 1 can move flexibly; when retracted, the housing 1 can be stably positioned. To ensure the synchronous rotation of the two bidirectional screws 31, two spur gears 35 are rotatably connected to the outside of one of the support plates 3. These gears are connected via a synchronous belt drive, and each gear is connected to one of the two bidirectional screws 31 via a connecting rod passing through the support plate 3. This achieves synchronous movement of the two moving wheels 34, ensuring the stability and balance of the housing 1 during movement and placement. The power for the moving assembly is provided by a second drive unit, which is an electric motor, installed on one side of the other support plate 3. This motor drives one of the bidirectional screws 31 to rotate, and then, through the transmission of the spur gears 35 and the synchronous belt, drives the other bidirectional screw 31 to rotate synchronously. Ultimately, this allows the moving wheels 34 to unfold or retract, meeting different usage requirements of the device.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
