Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery heat exchangers, and in particular to a low-energy heat pipe waste heat recovery heat exchanger. Background Technology

[0002] Waste heat recovery heat exchangers are devices used to recover and utilize waste heat generated during industrial processes. These devices can recover and reuse heat energy that would otherwise be wasted, improving energy efficiency and reducing energy consumption. Waste heat recovery systems are commonly used in industries such as steel, chemicals, power generation, and air conditioning.

[0003] Existing technologies, such as the utility model patent with publication number CN222812221U, disclose a waste heat recovery heat exchanger. This patent uses a heat exchanger shell, within which a heat exchange coil is fixedly connected. Both ends of the heat exchange coil are fixedly connected to reducing couplings. One end of one set of reducing couplings is fixedly connected to a first circulation pipe, and one end of the first circulation pipe is fixedly connected to a first flange. The other set of reducing couplings is fixedly connected to one end of a second circulation pipe, and one end of the second circulation pipe is fixedly connected to a second flange. This utility model has a compact internal structure, effectively improving heat exchange efficiency and enabling more complete recovery and utilization of waste heat. It also includes a fan to accelerate the heat exchange process and allows for rapid adjustment of the heat exchange rate when needed, improving the device's practicality. Furthermore, the flange connections facilitate disassembly and individual maintenance of each component, enhancing the device's convenience.

[0004] The inventors discovered in daily use that existing waste heat recovery heat exchangers, especially shell-and-tube and plate heat exchangers, are typically large, complex in structure, and heavy. This makes them inconvenient to move or redeploy, especially when maintenance, replacement, or relocation is required, which can present considerable difficulties. Furthermore, since manual handling is not possible, mechanical transport is necessary, which not only increases transportation costs but also results in long lead times from locating the machinery to hoisting it.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

A support ring is fixedly connected to the end of the support rod away from the slip ring. A threaded tube is rotatably connected to the end of the slip ring away from the device body.

[0029] 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.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 4 The present invention provides a low-energy heat pipe waste heat recovery heat exchanger, comprising: a body 2, a plurality of heat exchange plates 1 installed inside the body 2, a plurality of connectors 3 fixedly connected to both ends of the body 2, movable structures 4 on both sides of the body 2, and support structures 5 at both ends of the body 2.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The movable structure 4 includes four limiting blocks 409, which are arranged in pairs. Two pairs of limiting blocks 409 are fixed to both sides of the body 2. A sliding rod 410 is fixedly connected to the inner wall of each limiting block 409. A sliding plate 414 is slidably connected to the arc surface of the sliding rod 410. A movable plate 405 is fixedly connected to the side of the two sliding plates 414 that are close to each other. A threaded ring 404 is fixedly connected to the upper surface of the movable plate 405. Two fixing rods 401 are fixedly connected to both sides of the body 2. A servo motor 402 is installed at one of the close ends. A screw 403 is fixedly connected to the output end of the servo motor 402. The screw 403 is threadedly connected to a threaded ring 404. The screw 403 is slidably connected to a moving plate 405. A fixed plate 406 is rotatably connected to the lower end of the screw 403. The fixed plate 406 is fixedly connected to the body 2. A connecting shaft 407 is fixedly connected to the lower surface of the slide plate 414. A connecting frame 408 is rotatably connected to the lower end of the connecting shaft 407. A wheel 412 is rotatably connected to the inner wall of the connecting frame 408. When the heat exchanger needs to be moved, the servo motor 402 is started to run. The servo motor 402 drives the screw 403 to rotate. The screw 403 rotates on the fixed plate 406. The screw 403 drives the threaded ring 404 to rotate. The threaded ring 404 drives the moving plate 405 to move. The moving plate 405 drives the sliding plate 414 to move. The sliding plate 414 slides on the arc surface of the sliding rod 410. The sliding plate 414 drives the connecting shaft 407 to move. The connecting shaft 407 drives the connecting frame 408 to move. The connecting frame 408 drives the wheel 412 to move. The wheel 412 lifts the entire heat exchanger and then drives the heat exchanger to move. The arc surface of the wheel 412 has several slots 413, which are evenly distributed on the wheel 412. The groove 413 increases the friction between the wheel 412 and the contact surface, preventing the wheel 412 from slipping and wearing during use. Several limiting rods 411 are fixedly connected to the arc surface of the slide rod 410, and these limiting rods 411 are slidably connected to the slide plate 414. The limiting rods 411 limit the slide plate 414, preventing them from shifting during use and improving the stability of the slide plate 414. The fixing rod 401 has an "L"-shaped cross-section and is made of stainless steel. The stainless steel material increases the service life of the fixing rod 401 and prevents excessive corrosion during use.

[0033] In the embodiments of this utility model, please refer to Figure 1 and Figure 4The support structure 5 includes a lead screw 51, which is fixedly connected to the body 2.

A support ring 54 is fixedly connected to the end of the support rod 53 away from the slip ring 52. A threaded pipe 56 is rotatably connected to the end of the slip ring 52 away from the body 2. The threaded pipe 56 is rotatably connected to the lead screw 51. When it is necessary to support the external pipeline, the threaded pipe 56 is rotated and moved. The threaded pipe 56 moves on the lead screw 51, which drives the slip ring 52 to move. The slip ring 52 slides on the arc surface of the lead screw 51, which drives the support rods 53 to move. The support rods 53 drive the support ring 54 to move. After moving to the appropriate position, the support ring 54 supports the external pipeline. Several friction grooves 57 are opened on the arc surface of the threaded pipe 56, and the friction grooves 57 are evenly distributed on the threaded pipe 56. The friction groove 57 increases the friction between the threaded pipe 56 and the hand, preventing slippage when rotating the threaded ring 404. A protective sleeve 55 is fixedly connected to the inner wall of the support ring 54; the protective sleeve 55 has an annular cross-section. The protective sleeve 55 protects the external pipe, preventing excessive wear on the support ring 54 when supporting the external pipe.

[0034] The working principle of the low-energy heat pipe waste heat recovery heat exchanger provided by this utility model is as follows: When the heat exchanger needs to be moved, the servo motor 402 is started to operate. The servo motor 402 drives the screw 403 to rotate. The screw 403 rotates on the fixed plate 406, which in turn drives the threaded ring 404 to rotate. The threaded ring 404 drives the moving plate 405 to move, which in turn drives the sliding plate 414 to move. The sliding plate 414 slides on the arc surface of the sliding rod 410, which in turn drives the connecting shaft 407 to move. The connecting shaft 407 drives the connecting frame 408 to move. The connecting frame 408 moves the wheel 412, which lifts the entire heat exchanger. The groove 413 increases the friction between the wheel 412 and the contact surface, preventing the wheel 412 from slipping and wearing during use. The limiting rod 411 limits the slide plate 414, preventing it from shifting during use and improving the stability of the slide plate 414. The stainless steel material increases the service life of the fixing rod 401 and prevents it from rusting excessively during use.

[0035] When external pipes need support, the threaded tube 56 is rotated and moved. The threaded tube 56 moves on the lead screw 51, which drives the slip ring 52 to move. The slip ring 52 slides on the arc surface of the lead screw 51, and the slip ring 52 drives the support rod 53 to move. The support rod 53 drives the support ring 54 to move. After moving to the appropriate position, the support ring 54 supports the external pipe. The friction groove 57 can increase the friction between the threaded tube 56 and the hand to prevent slippage when rotating the threaded ring 404. The protective sleeve 55 can protect the external pipe and prevent the support ring 54 from excessive wear when supporting the external pipe.
