Description

Technical Field

[0001] This invention relates to the field of smoked duck production technology, specifically to a shell-and-tube heat recovery heat exchanger for smoked duck to prevent heat loss. Background Technology

[0002] In the traditional processing of poultry products such as smoked duck and roasted duck, the smoking or roasting process is crucial in determining the product's flavor, color, and texture. This process typically takes place in a closed or semi-closed smoking oven, requiring the oven temperature to be maintained within a specific range of approximately 150°C to 220°C for an extended period. To maintain the oven temperature and create the necessary smoking environment, high-temperature flue gas generated by the burners needs to be continuously or intermittently introduced into the oven.

[0003] Chinese Patent CN209894003U, authorized and published on January 3, 2020, discloses a shell-and-tube heat recovery heat exchanger for preventing heat loss in duck production. The heat exchanger includes a body, a mounting rod, and a drain port. The left and right ends of the body are connected to a connecting cover via flange connectors. An air inlet is provided in the middle of the connecting cover, and a first sealing gasket is connected to the surface of the connecting cover. An air inlet is provided on the connecting cover on the left side of the body. An outer tube is provided on the outside of the inner tube, and elbow tubes are connected between the inner tubes. An air outlet is provided in the middle of the connecting cover on the right side of the body.

[0004] In the aforementioned application documents, glass fiber is used as the insulation layer to prevent heat loss. However, in order to improve the heat exchange efficiency, when a rapidly flowing liquid that needs to be heated is introduced, the heat exchange sleeve inside the device is in a stationary state, which affects the heat exchange efficiency of the device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a shell-and-tube heat recovery heat exchanger for smoking duck to prevent heat loss, thus solving the problems mentioned in the background section. To achieve the above objectives, this invention is implemented through the following technical solution: a shell-and-tube heat recovery heat exchanger for smoking duck to prevent heat loss, comprising: The heat exchange chamber is equipped with an air inlet, an exhaust outlet, a liquid inlet, and a liquid outlet on its sides. The sides of the air inlet and the exhaust outlet are each equipped with a connecting hose.

Through the arrangement of the scale treatment component, the treatment brush one reciprocates on the inner wall of the heat exchange chamber, scraping away the scale on the inner wall of the heat exchange chamber, preventing scale accumulation from affecting the water storage capacity of the heat exchange chamber, thereby improving its heat exchange efficiency.

[0010] Preferably, the second sliding plate is located inside the heat exchange chamber and is in a sliding connection with the heat exchange chamber.

An arc-shaped rod is fitted to the side of the second hydraulic chamber. A rotating block is rotatably connected to the side of the fixed rod. A force-bearing plate and a second treatment brush are fixedly connected to the side of the rotating block. By configuring the auxiliary component, multiple second treatment brushes can reciprocate at a certain angle to scrape away scale on the sidewalls of the heat exchange chamber, further improving the cleaning effect.

[0012] Preferably, the end of the spring away from the force-bearing rod is mounted on the inner wall of the hydraulic chamber.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Example 1, please refer to Figures 1-4 A shell-and-tube heat recovery heat exchanger for smoked duck to prevent heat loss, comprising: The heat exchange chamber 100 is equipped with an air inlet 200, an exhaust port 300, a liquid inlet 400 and a liquid outlet 500 on its sides. The sides of the air inlet 200 and the exhaust port 300 are each equipped with a connecting hose 600. A fixed chamber 701 is mounted on the side of the heat exchange chamber 100, and an impeller 702 is rotatably connected inside the fixed chamber 701. During heat exchange operation, the air inlet 200 is connected to an external heat transfer pipe, and heated gas is introduced into the air inlet 200. A liquid pump is used to introduce the liquid to be heated into the heat exchange chamber 100 through the air inlet 200. The rapidly flowing liquid drives the impeller 702, which is rotatably connected to the fixed chamber 701, to rotate.

[0027] The heat exchange chamber 100 has a sliding plate 711 internally connected to it. A transmission component for transmission is assembled between the impeller 702 and the sliding plate 711. The transmission component includes a rotating rod 703 fixed to the side of the impeller 702, and a bevel gear 704 fixedly connected to the side of the rotating rod 703. When the impeller 702 rotates, it drives the rotating rod 703 fixedly connected to it to rotate, and the rotating rod 703 in the rotating state drives the bevel gear 704 fixedly connected to it to rotate.

[0028] A rotating rod 705 is rotatably connected to the top of the heat exchange chamber 100. A bevel gear 706 and a sprocket 707 are fixedly connected to the outer side of the rotating rod 705. The bevel gear 706 meshes with the bevel gear 704. When the bevel gear 704 rotates, it drives the bevel gear 706 meshing with it to rotate. The rotating bevel gear 706 then drives the rotating rod 705 fixedly connected to it to rotate.

[0029] A chain 708 is mounted on the outer side of sprocket 707. A reciprocating screw 709 is rotatably connected inside the heat exchange chamber 100. A sliding plate 711 is located on the outer side of the reciprocating screw 709 and is connected to the reciprocating screw 709 by a thread. A sprocket 710 is fixedly connected to the outer side of the reciprocating screw 709. The end of the chain 708 away from sprocket 707 is mounted on the outer side of sprocket 710. A heat exchange sleeve 712 is mounted on the side of the sliding plate 711 and is mounted between two connecting hoses 600. When the sliding plate 711 reciprocates in the vertical direction, it drives the heat exchange sleeve 712 mounted on the side of the sliding plate 711 to reciprocate a certain distance in the vertical direction, thereby improving the heat exchange efficiency of the device.

[0030] In use, the air inlet 200 is connected to the external heat-conducting pipe body, and heated gas is introduced into the air inlet 200. The heated gas then flows into the heat exchange sleeve 712 through the connecting hose 600. Simultaneously, a liquid pump is used to introduce the liquid to be heated into the heat exchange chamber 100 through the air inlet 200. The rapidly flowing liquid drives the impeller 702, which is rotatably connected to the fixed chamber 701, to rotate. This causes the impeller 702 to drive the rotating rod 703, which is fixedly connected to it, to rotate. The rotating rod 703 then drives the bevel gear 704, which is fixedly connected to it, to rotate. This causes the bevel gear 704 to drive the bevel gear 706, which meshes with it, to rotate. The rotating bevel gear 706 then drives the rotating rod 704, which is fixedly connected to it, to rotate. Rotating rod 705 causes the rotating rod 705 to drive the sprocket 707 fixedly connected to it to rotate. In conjunction with the chain 708 mounted on the outside of sprocket 707, sprocket 710, which is connected to sprocket 707 via chain 708, rotates. The rotating sprocket 710 can drive the reciprocating screw 709 fixedly connected to it to rotate. The sliding plate 711, which is threadedly mounted on the outside of the reciprocating screw 709, is simultaneously restricted by the heat exchange chamber 100 slidably connected to it. As the reciprocating screw 709 rotates, the sliding plate 711 moves back and forth in the vertical direction, which can drive the heat exchange sleeve 712 mounted on the side of the sliding plate 711 to move back and forth a certain distance in the vertical direction.

[0031] Example 2, please refer to Figures 1-6 Based on Embodiment 1, the heat exchange chamber 100 is equipped with a scale treatment component 800, which includes a rotating rod 801 mounted on the bottom of a reciprocating screw 709. When the reciprocating screw 709 is rotating, it can drive the rotating rod 801, which is fixedly connected to it, to rotate.

[0032] A bevel gear 802 is fixedly connected to the outer side of the rotating rod 801. When the rotating rod 801 rotates, it drives the bevel gear 802 fixedly connected to it to rotate.

[0033] The heat exchange chamber 100 is internally connected to a reciprocating screw 2 803, and a bevel gear 4 804 is fixedly connected to the side of the reciprocating screw 2 803. The bevel gear 4 804 meshes with the bevel gear 3 802. When the bevel gear 3 802 rotates, it drives the bevel gear 4 804 to rotate, which in turn drives the reciprocating screw 2 803 fixedly connected to it to rotate.

[0034] A sliding plate 805 is threadedly connected to the outer side of the reciprocating screw 803. The sliding plate 805 is located inside the heat exchange chamber 100 and is slidably connected to it. A treatment brush 806 is fixedly connected to the side of the sliding plate 805. When the sliding plate 805 reciprocates horizontally, it drives the treatment brush 806 to reciprocate as well, scraping away scale on the inner wall of the heat exchange chamber 100. This prevents scale buildup from affecting the water storage capacity of the heat exchange chamber 100, thereby improving its heat exchange efficiency.

[0035] In use, based on Embodiment 1, when the reciprocating screw 709 is in a rotating state, it can drive the rotating rod 801 fixedly connected to it to rotate, so that the rotating rod 801 drives the bevel gear 802 fixedly connected to it to rotate. The rotating bevel gear 802 can drive the bevel gear 804 meshing with it to rotate, so that the bevel gear 804 drives the reciprocating screw 803 fixedly connected to it to rotate. Meanwhile, the sliding plate 805, which is threadedly mounted on the outside of the reciprocating screw 803, is simultaneously restricted by the heat exchange chamber 100 slidably connected to it. So that during the rotation of the reciprocating screw 803, the sliding plate 805 moves back and forth in the horizontal direction. The sliding plate 805 in the moving state can drive the treatment brush 806 fixedly connected to it to move back and forth together to scrape off the scale on the inner wall of the heat exchange chamber 100.

[0036] Example 3, please refer to Figures 1-8 Based on Embodiments 1 and 2, an auxiliary component 900 is installed inside the heat exchange chamber 100. The auxiliary component 900 includes a fixed rod 901 fixed inside the heat exchange chamber 100 and a hydraulic chamber 902. A force-bearing rod 903 is slidably connected to the side of the hydraulic chamber 902 via a piston. When the sliding plates 805 on both sides move to the positions on both sides of the heat exchange chamber 100, the sliding plates 805 can press the force-bearing rod 903, and the force-bearing rod 903 pressed by the sliding plates 805 can move to the side.

[0037] A spring 904 is mounted on the side of the force-bearing rod 903. The end of the spring 904 away from the force-bearing rod 903 is mounted on the inner wall of hydraulic chamber 1 902. A hydraulic hose 905 is mounted on the top of hydraulic chamber 1 902. A hydraulic chamber 2 906 is mounted on the side of the fixing rod 901. The end of the hydraulic hose 905 away from hydraulic chamber 1 902 is mounted on the side of hydraulic chamber 2 906 and communicates with hydraulic chamber 2 906. An arc-shaped rod 907 is mounted on the side of hydraulic chamber 2 906. When the oil in hydraulic chamber 2 906 is squeezed and flows towards the side closer to the arc-shaped rod 907, it can drive the arc-shaped rod 907, which is slidably connected to hydraulic chamber 2 906 via a piston, to move out of hydraulic chamber 2 906.

[0038] A rotating block 908 is rotatably connected to the side of the fixed rod 901. A force-bearing plate 909 and a second treatment brush 910 are fixedly connected to the side of the rotating block 908. The force-bearing plate 909 is located on the side of the arc-shaped rod 907 and is fixed to the arc-shaped rod 907. When the rotating block 908 rotates reciprocally, it drives multiple second treatment brushes 910 to rotate reciprocally at a certain angle, thereby scraping away scale on the side wall of the heat exchange chamber 100 and further improving its cleaning effect.

[0039] In use, based on Embodiments 1 and 2, when the sliding plates 805 on both sides move to the positions on both sides of the heat exchange chamber 100, the sliding plates 805 can press the force rod 903. The force rod 903, pressed by the sliding plates 805, can move laterally. This, combined with the hydraulic chamber 902 connected to the force rod 903 via a piston, causes the force rod 903 to press the oil originally stored in the hydraulic chamber 902 as it moves into it. The oil, under pressure, flows into the hydraulic hose 905 connected to the hydraulic chamber 902, further pressing the oil originally stored in the hose. A portion of the oil in the hydraulic hose 905 then flows into the hydraulic chamber 906 connected to the hose, causing the oil in the hydraulic chamber 906 to be compressed and pushed towards... The flow near the arc-shaped rod 907 causes the arc-shaped rod 907, which is connected to the hydraulic chamber 2 906 by a piston sliding connection, to move out of the hydraulic chamber 2 906. As the arc-shaped rod 907 moves, the force plate 909, which is fixedly connected to the arc-shaped rod 907, rotates at a certain angle. The rotating arc-shaped rod 907 then drives the rotating block 908, which is fixedly connected to it, to rotate. This causes the rotating block 908 to drive the processing brush 910, which is fixedly connected to it, to rotate at a certain angle. As the sliding plate 805 continues to rotate and moves away from the force plate 903, the force plate 903 loses its restraint and can be reset under the action of the spring 904. Similarly, the processing brush 910 is reset. The multiple processing brushes 910, which are rotating back and forth at a certain angle, can scrape off the scale on the side wall of the heat exchange chamber 100.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
