[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat transfer element for a waste gas treatment heat exchanger. Background Technology

[0002] A waste gas treatment heat exchanger is a device used to recover and exchange heat energy during waste gas treatment. Tubular heat exchangers are commonly used as heat transfer elements in waste gas treatment heat exchangers. A tubular heat exchanger is a common heat exchange device, typically composed of multiple tubes through which fluid flows, and heat is transferred through the tube walls to the external fluid or vice versa. Some current tubular heat exchangers are relatively heavy and large, often requiring hoisting equipment for installation. However, the smooth surface of the tubular heat exchanger presents challenges when using hoisting equipment, especially during lifting and positioning, which can easily lead to slippage, displacement, or difficulty in precise placement. Utility Model Content

[0003] The purpose of this invention is to address the issue that some current tubular heat exchangers have relatively heavy structures and large volumes, and their size and weight usually require hoisting equipment for installation. However, the relatively smooth exterior of tubular heat exchangers poses certain challenges when using hoisting equipment, especially during hoisting and positioning, which can easily lead to problems such as the heat exchanger sliding, shifting, or being difficult to place accurately. Therefore, this invention proposes a heat transfer element for a waste gas treatment heat exchanger.

[0004] The technical solution of this utility model is as follows: A heat transfer element for a waste gas treatment heat exchanger includes a tubular heat exchanger body, and further includes: a pair of support sleeves sleeved on the tubular heat exchanger body, wherein the support sleeves are provided with a plurality of locking grooves arranged in a circumferential array; a sliding clamp block slidably disposed on the support sleeves, wherein the sliding clamp block is provided with a spring mechanism for locking into the locking grooves; and a hanging ring installed on the sliding clamp block.

[0005] Optionally, the rebound mechanism includes a sliding groove formed in the sliding clamp block. The inner wall of the sliding groove is provided with an interconnected telescopic groove and a sliding groove. A push spring is fixedly connected inside the telescopic groove. A sliding block that engages with a locking groove is fixedly connected to one end of the push spring away from the inner wall of the telescopic groove.

[0006] Optionally, the rebound mechanism further includes a stop plate disposed in the sliding groove. One end of the stop plate is fixedly connected to the sliding block. The sliding block has an inclined stop groove for the stop plate to be inserted into. The other end of the stop plate is fixedly connected to a pressing plate. A return spring is fixedly connected to the sliding clamp. The end of the return spring away from the sliding clamp is fixedly connected to the pressing plate.

[0007] Optionally, the pressing plate is provided with anti-slip texture.

[0008] Optionally, each sliding clamp is fixedly connected to a stop block, and a fixed support rod is fixedly connected to the end of each stop block away from the sliding clamp block. The end of each fixed support rod away from the stop block is fixedly connected to a hanging ring.

[0009] Optionally, the support sleeve is internally fixedly connected with a plurality of connecting blocks arranged in a circumferential array, and the end of each connecting block away from the support sleeve is fixedly connected to the outer wall of the tubular heat exchanger body.

[0010] Optionally, a pair of the support sleeves are symmetrically arranged at the center of the tubular heat exchanger body.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model utilizes the cooperation of structures such as support sleeve rod, locking groove, sliding clamp block, spring mechanism and hanging ring to provide a hanging ring as a fixing point for the body of the tubular heat exchanger during the hoisting process, ensuring that the equipment does not accidentally slide or tilt during the hoisting process, and reducing the safety hazards caused by sliding or instability of the equipment during the hoisting process.

[0013] The additional hanging ring can move freely on the support sleeve, ensuring that the tube heat exchanger body can face downwards at any position. This allows for flexible adjustment of the position of the tube heat exchanger body, ensuring that the equipment is in the appropriate angle and position, simplifying the installation work, and improving installation efficiency and accuracy.

[0026] Example

[0027] like Figures 1 to 5 As shown, the present invention proposes a heat transfer element for a waste gas treatment heat exchanger, including a tubular heat exchanger body 1, and further including a pair of support sleeves 2 sleeved on the tubular heat exchanger body 1. The pair of support sleeves 2 are symmetrically arranged at the center of the tubular heat exchanger body 1. The symmetrical arrangement of the pair of support sleeves 2 at the center of the tubular heat exchanger body 1 ensures that the tubular heat exchanger body 1 will not tilt in the air due to center offset when the lifting device is hoisted. The support sleeve 2 has multiple connecting blocks 21 arranged in a circular array inside. The ends of the connecting blocks 21 furthest from the support sleeve 2 are fixedly connected to the outer wall of the tubular heat exchanger body 1. The support sleeve 2 has multiple locking grooves 22 arranged in a circular array. These locking grooves 22 are shallow recesses in the support sleeve 2 and do not affect the overall strength of the support sleeve 2. A sliding clamping block 3 is slidably mounted on the support sleeve 2. The sliding clamping block 3 has a spring-loaded mechanism that engages with the locking groove 22 for locking. A hanging ring 304 is installed on the sliding clamping block 3. A pair of hanging rings 304 ensures that the lifting device is symmetrically hung, thereby ensuring that the lifted tubular heat exchanger body 1 is suspended horizontally. The hanging ring 304 is an important component, mainly used for bearing and securing loads. It is usually used in conjunction with slings, straps, chains, or other lifting devices to ensure that heavy objects can be safely lifted, transported, or secured.

[0028] Furthermore, the rebound mechanism includes a sliding groove 301 formed within the sliding clamp 3. The inner wall of the sliding groove 301 has interconnected telescopic grooves 31 and 32. A push spring 33 is fixedly connected inside the telescopic groove 31. The push spring 33 causes the sliding block 34, which is not blocked, to automatically protrude from the telescopic groove 31, and the sliding block 34 is normally engaged in the locking groove 22. The end of the push spring 33 away from the inner wall of the telescopic groove 31 is fixedly connected to the sliding block 34, which engages in the locking groove 22.

[0029] The rebound mechanism also includes a stop plate 36 disposed within the sliding groove 32. One end of the stop plate 36 is fixedly connected to the sliding block 34. The sliding block 34 has an inclined groove 35 for the stop plate 36 to engage. The inclined groove 35 causes the sliding block 34 to retract into the telescopic groove 31 after being stopped by the end of the stop plate 36. The other end of the stop plate 36 is fixedly connected to a pressing plate 37. The pressing plate 37 has anti-slip texture 39. The anti-slip texture 39 refers to a texture with a certain shape and structure formed on the surface of an object through a specific processing technology, used to increase the friction of the object surface and prevent slipping. A return spring 38 is fixedly connected to the sliding clamp 3. The end of the return spring 38 away from the sliding clamp 3 is fixedly connected to the pressing plate 37.

[0030] Furthermore, each sliding clamp 3 is fixedly connected to a stop block 302, and each stop block 302 is fixedly connected to a fixed support rod 303 at the end away from the sliding clamp 3. The end of the fixed support rod 303 away from the stop block 302 is fixedly connected to the hanging ring 304.

[0031] In this embodiment, when the exhaust gas treatment heat exchanger requires the use of heat transfer elements, such as... Figure 1 As shown, to ensure the corresponding position of the tubular heat exchanger body 1 is downward, simply adjust the sliding clamps 3 on the pair of support rods 2 to the opposite position to the downward orientation. Then, when using the sliding clamps 3 to lift the tubular heat exchanger body 1, gravity will cause the corresponding position to be downward. Simultaneously, during the lifting process, the binding ropes will not slip due to the smooth surface of the tubular heat exchanger body 1. When adjusting the position of the sliding clamps 3 on the support rods 2, as... Figure 3 As shown, simply press the pressing plate 37 towards the sliding clamp 3. The anti-slip texture 39 on the pressing plate 37 prevents the hand from slipping when in contact with it. The pressing plate 37 will cause the abutment 36 to slide along the sliding groove 32. Then, the abutment 36 will cause the inclined abutment groove 35 to engage with the inclined abutment groove 35 inside the sliding block 34. Since the inclined abutment groove 35 is inclined, the sliding block 34 will retract into the telescopic groove 31 after the abutment 36 engages with the inclined abutment groove 35. At this time, the sliding clamp 3 can slide on the support sleeve 2, and it can slide smoothly on the support sleeve 2 through the sliding groove 301 inside the sliding clamp 3. Next, as the sliding clamp 3 slides, it sequentially moves the corresponding abutment 302, fixed support rod 303, and hanging ring 304 until the sliding clamp 3 moves to the appropriate locking groove 22 on the support sleeve rod 2. At this point, the pressing plate 37 can be released, and the pressing plate 37 returns to its original position through the elastic thrust of the return spring 38. Then, the abutment 36 can no longer hold the sliding block 34, and the sliding block 34 pushes the elastic thrust of the spring 33 in the telescopic groove 31, causing the sliding block 34 to re-engage in the corresponding locking groove 22. Finally, the locking of the sliding clamp 3 on the corresponding support sleeve rod 2 is completed.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
