Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, and in particular to an anti-clogging silicon carbide heat exchanger. Background Technology

[0002] A heat exchanger is a device that enables heat transfer between materials. Through different structural designs, it allows two or more fluids to exchange heat without mixing. It is widely used in chemical, power, and HVAC fields to achieve purposes such as heating, cooling, and condensation.

[0003] In existing technologies, anti-clogging silicon carbide heat exchangers often struggle to automatically clean scale from the outside of the heat exchange tubes, requiring periodic manual disassembly and cleaning. This is not only time-consuming and labor-intensive but also prone to damaging the equipment. Over time, scale buildup can significantly reduce heat exchange efficiency and even cause pipe blockages, greatly impacting the heat exchanger's lifespan and operational stability.

[0004] To address the above problems, an anti-clogging silicon carbide heat exchanger is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-clogging silicon carbide heat exchanger, which aims to improve the problem that existing anti-clogging silicon carbide heat exchangers often have difficulty in automatically cleaning scale on the outside of the heat exchange tubes, requiring manual disassembly and cleaning periodically. This is not only time-consuming and labor-intensive, but also easily damages the equipment. After long-term use, scale accumulation will lead to a significant decrease in heat exchange efficiency and even cause pipe blockage, which greatly affects the service life and operational stability of the heat exchanger.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-clogging silicon carbide heat exchanger, comprising two sleeves, a movable seat slidably connected inside the sleeves, a heat exchanger body fixedly connected to the top of the movable seat, a connecting block fixedly connected between the two sleeves, an adjustment component provided on the outside of the sleeves, multiple silicon carbide heat exchange tubes installed inside the heat exchanger body, and a scale cleaning component provided on the outside of the silicon carbide heat exchange tubes; The scale cleaning component includes a support block, which is fixedly connected to the outside of the heat exchanger body. A motor is fixedly connected to the outside of the support block, and a turntable is fixedly connected to the output end of the motor. A rotating shaft is fixedly connected to the outer edge of the turntable, and a hollow shell is slidably connected to the outside of the rotating shaft. A connecting rod is fixedly connected to the outside of the hollow shell, and multiple cleaning discs are fixedly connected to the outside of the connecting rod. Multiple sliders are fixedly connected to the outside of the cleaning discs.

[0007] As a further description of the above technical solution: The adjustment assembly includes a second motor and a rack. The rack is fixedly connected to the inner wall of the movable seat on the outside. The second motor is fixedly connected to the outside of the sleeve on the outside. A rotating rod is fixedly connected to the output end of the second motor. Two gears are fixedly connected to the outside of the rotating rod, and the gears are meshed with the rack.

[0008] As a further description of the above technical solution: The connecting rod is slidably connected to the outside of the heat exchanger body.

[0009] As a further description of the above technical solution: The slider is slidably connected to the inner wall of the heat exchanger body on its outer side.

[0010] As a further description of the above technical solution: The outer side of the rotating rod is rotatably connected to the inside of the sleeve, and the outer side of the rotating rod is rotatably connected to the inside of the connecting block.

[0011] As a further description of the above technical solution: The bottom of the sleeve is fixedly connected to a mounting base.

[0012] As a further description of the above technical solution: The cleaning disc is slidably connected to the inner wall of the heat exchanger body on its outer side.

[0013] As a further description of the above technical solution: The silicon carbide heat exchange tube is made of silicon carbide material.

[0014] This utility model has the following beneficial effects: 1. In this utility model, after the motor is started, it drives the turntable to rotate, and the rotating shaft on the edge of the turntable also makes a circular motion. Since the rotating shaft is slidably connected to the hollow shell, the hollow shell and the connecting rod connect multiple cleaning discs. The slider on the cleaning disc slides on the inner wall of the heat exchanger body, so that the cleaning disc can reciprocate along the direction of the silicon carbide heat exchange tube inside the heat exchanger body, realizing the automatic cleaning of scale on the outside of the silicon carbide heat exchange tube, avoiding the problem of reduced heat exchange efficiency and pipe blockage caused by scale accumulation, extending the service life of the heat exchanger, and ensuring the efficient and stable operation of the heat exchanger.

[0015] 2. In this utility model, the motor is started, and its output end drives the rotating rod to rotate. The two gears on the rotating rod rotate accordingly. Since the gears are meshed with the rack on the inner wall of the moving seat, the rack drives the moving seat to slide up and down in the sleeve under the rotation of the gears. This allows for flexible adjustment of the position of the heat exchanger body, making it convenient to install, disassemble and repair the heat exchanger, thus improving the convenience of operation and maintenance efficiency.

Motor 3 drives the turntable 9 to rotate, providing power for the scale cleaning component. Turntable 9 drives the rotating shaft 4 to make circular motion. The rotating shaft 4 connects the turntable 9 and the hollow shell 5 to transmit motion. The hollow shell 5 connects the rotating shaft 4 and the connecting rod 6, and drives the cleaning disc 7 to move under the action of the rotating shaft 4. The connecting rod 6 connects the hollow shell 5 and the cleaning disc 7, and slides on the outside of the heat exchanger body 1 to ensure the stability of the movement of the cleaning disc 7. The cleaning disc 7 is used to clean the scale on the outside of the silicon carbide heat exchange tube 10. The slider 8 is used to slide and cooperate with the inner wall of the heat exchanger body 1 to ensure that the cleaning disc 7 makes stable reciprocating motion along the direction of the silicon carbide heat exchange tube 10, so as to achieve effective cleaning.

[0021] Reference Figures 1-6 The adjustment assembly includes a second motor 14 and a rack 15. The rack 15 is fixedly connected to the inner wall of the movable seat 12 on the outside. The second motor 14 is fixedly connected to the outside of the sleeve 11 on the outside. A rotating rod 17 is fixedly connected to the output end of the second motor 14. Two gears 16 are fixedly connected to the outside of the rotating rod 17. The gears 16 are meshed with the rack 15.

[0022] Specifically, motor 14 provides power to drive rotating rod 17 to rotate; rotating rod 17 connects motor 14 to two gears 16 to transmit the power of motor 14; gear 16 meshes with rack 15 to convert the rotational motion of rotating rod 17 into linear motion; rack 15 cooperates with gear 16, and under the drive of gear 16, drives the fixedly connected movable seat 12 to slide up and down inside sleeve 11, thereby realizing the adjustment of the position of heat exchanger body 1 fixed on top of movable seat 12, which facilitates the installation, maintenance and other operations of heat exchanger body 1.

[0023] Reference Figures 1-6 The outer side of the connecting rod 6 is slidably connected to the outer side of the heat exchanger body 1, the outer side of the slider 8 is slidably connected to the inner wall of the heat exchanger body 1, the outer side of the rotating rod 17 is rotatably connected to the inside of the sleeve 11, the outer side of the rotating rod 17 is rotatably connected to the inside of the connecting block 13, the bottom of the sleeve 11 is fixedly connected to the mounting base 18, the outer side of the cleaning disc 7 is slidably connected to the inner wall of the heat exchanger body 1, and the material of the silicon carbide heat exchange tube 10 is silicon carbide.

[0024] Specifically, the connecting rod 6 connects the hollow shell 5 and the cleaning disc 7, with its outer side slidably connected to the outer side of the heat exchanger body 1. Driven by the hollow shell 5, it ensures that the cleaning disc 7 moves smoothly along the heat exchanger body 1, thus cleaning the scale on the silicon carbide heat exchange tube 10. The slider 8 slides against the inner wall of the heat exchanger body 1, limiting the movement trajectory of the cleaning disc 7 and ensuring that the cleaning disc 7 reciprocates stably along the direction of the silicon carbide heat exchange tube 10 inside the heat exchanger body 1. The rotating rod 17 transmits the power of the motor 14, with its outer side rotatably connected to the inside of the sleeve 11 and the connecting block 13, ensuring the stability of the rotating rod 17 during rotation. The smooth operation of the gear 16 drives the rack 15 to slide the moving seat 12; the mounting seat 18 at the bottom of the sleeve 11 is used to fix the entire anti-clogging silicon carbide heat exchanger in a designated position, providing stable support; the cleaning disc 7 is used to clean the scale on the outside of the silicon carbide heat exchange tube 10, and its outside is slidably connected to the inner wall of the heat exchanger body 1. With the cooperation of the connecting rod 6 and the slider 8, the silicon carbide heat exchange tube 10 is effectively cleaned; the silicon carbide heat exchange tube 10 is made of silicon carbide material to achieve efficient heat transfer. Because its material has excellent thermal conductivity, wear resistance and corrosion resistance, it ensures the stable and reliable operation of the heat exchanger.

[0025] Working principle: When the position of the heat exchanger body 1 needs to be adjusted, the motor 14 installed on the outside of the sleeve 11 starts, and its output end drives the rotating rod 17 to rotate. The rotating rod 17 passes through the sleeve 11 and the connecting block 13 and rotates inside it, while simultaneously driving the two gears 16 fixed on the rotating rod 17 to rotate synchronously. Since the gears 16 mesh with the rack 15 on the inner wall of the moving seat 12, when the gears 16 rotate, the rack 15 drives the moving seat 12 to slide up and down inside the sleeve 11, thereby realizing the flexible adjustment of the position of the heat exchanger body 1. Regarding the cleaning of scale on the silicon carbide heat exchanger tube 10, the support block 2 is fixed to the outside of the heat exchanger body 1. After the motor 3 installed on it is started, it drives the turntable 9 connected to it to rotate, and the rotating shaft 4 on the edge of the turntable 9 makes a circular motion accordingly. Because the rotating shaft 4 is slidably connected to the hollow shell 5, and the hollow shell 5 is connected to multiple cleaning discs 7 through the connecting rod 6, and the connecting rod 6 slides on the outside of the heat exchanger body 1, and the slider 8 on the cleaning disc 7 slides on the inner wall of the heat exchanger body 1, the circular motion of the rotating shaft 4 can be converted into the reciprocating motion of the cleaning disc 7 along the direction of the silicon carbide heat exchanger tube 10 inside the heat exchanger body 1, thereby effectively cleaning the scale on the outside of the silicon carbide heat exchanger tube 10.
