Description

Technical Field

[0001] This utility model relates to the technical field of waste heat recovery heat exchange devices, and specifically discloses an energy-saving waste heat recovery heat exchange device. Background Technology

[0002] Waste heat recovery heat exchangers are typically installed on the boiler flue. The flue gas emitted during boiler operation contains a large amount of heat, and waste heat recovery devices are commonly used to recover this heat. The flue gas enters the waste heat recovery device, while water from the boiler enters the water tank at the top of the device via a pump and pipes. The flue gas comes into contact with the heat pipes inside the device, heating them. The heat pipes absorb the heat from the flue gas and conduct it to the water in the tank, heating the water there. The heated water then flows back into the boiler through the outlet, reducing the boiler's energy consumption and making the boiler more energy-efficient and environmentally friendly during operation.

[0003] In existing technologies, common energy-saving and environmentally friendly waste heat recovery heat exchangers absorb heat from the flue gas in the boiler flue. These devices are equipped with a cover; opening the cover allows for internal maintenance, and closing it after maintenance is complete. The cover is secured to the device by three handwheels and screws. Opening the cover requires turning each handwheel to disengage it from the screws, and closing it requires tightening each handwheel. This cumbersome process makes maintenance inconvenient. Therefore, an energy-saving waste heat recovery heat exchanger is needed to address this issue. Utility Model Content

[0004] This utility model proposes an energy-saving waste heat recovery heat exchange device. The cover and body of the box are connected by a snap-fit ​​method, which makes installation and disassembly convenient and easy to maintain.

[0005] This utility model is implemented as follows: an energy-saving waste heat recovery heat exchange device includes a box body and a box cover. First connecting blocks are fixedly connected to both ends of the box cover, and second connecting blocks are fixedly connected to both ends of the box body. Each of the two second connecting blocks has a connecting groove matching the first connecting block on its front end face. Each of the two connecting grooves has a locking groove on its upper and lower end faces. The two first connecting blocks are slidably connected to the two connecting grooves. Each of the two first connecting blocks has an installation groove inside. A U-shaped plate is slidably connected inside each of the two installation grooves. Four symmetrically distributed slots are through-holes on the outer walls of each of the two U-shaped plates. Two symmetrically distributed locking rods are slidably connected inside each of the two first connecting blocks. Short columns are fixedly connected to both ends of the locking rods. The short columns are slidably connected to the multiple slots, and one end of each locking rod is engaged inside the multiple locking grooves.

[0006] To facilitate the rebound of the locking rod, as a preferred energy-saving waste heat recovery heat exchange device of this utility model, two symmetrically distributed springs are provided between the U-shaped plate and the inner wall of the mounting groove.

[0008] To facilitate the handling of the lid, as a preferred energy-saving waste heat recovery heat exchange device of this utility model, the front end face of the lid is fixedly connected with two symmetrically distributed second handles.

[0009] In order to facilitate the sliding of the clamp rod into the first connecting block by the pressure of the second connecting block, as a preferred embodiment of the energy-saving waste heat recovery heat exchange device of this utility model, the end of the clamp rod extending to the outside of the first connecting block is inclined.

[0010] To prevent the clamping rod from rotating, the clamping rod, as an energy-saving waste heat recovery heat exchange device of this utility model, preferably has a rectangular cross-section.

[0011] In order to maintain a good seal between the lid and the body, as a preferred embodiment of the energy-saving waste heat recovery heat exchange device of this utility model, a sealing ring is provided on the rear end face of the lid.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0023] Please see Figure 1-6 An energy-saving waste heat recovery heat exchange device includes a housing 1 and a housing cover 2. First connecting blocks 3 are fixedly connected to both ends of the housing cover 2. Second connecting blocks 4 are fixedly connected to both ends of the housing 1. Connecting grooves matching the first connecting blocks 3 are opened on the front ends of the two second connecting blocks 4. Slots 12 are opened on the upper and lower ends of the two connecting grooves. The two first connecting blocks 3 are slidably connected to the two connecting grooves. Installation grooves 5 are opened inside the two first connecting blocks 3. U-shaped plates 6 are slidably connected inside the two installation grooves 5. Four symmetrically distributed slots 9 are opened through the outer walls of the two U-shaped plates 6. Two symmetrically distributed clamping rods 10 are slidably connected inside the two first connecting blocks 3. Short columns 11 are fixedly connected to both ends of the clamping rods 10. The short columns 11 are slidably connected to the slots 9. One end of each clamping rod 10 is engaged inside the slots 12.

[0024] In this embodiment: When disassembling the lid 2, grasp the two second handles 13 with both hands, hook the first handle 8 with the index and middle fingers of both hands respectively, and pull the first handle 8 forward. The first handle 8 drives the sliding rod 7 to slide forward, which in turn drives the U-shaped plate 6 to slide forward. The U-shaped plate 6 drives the upper and lower locking rods 10 to slide inward through the slot 9 and the short post 11, so that the locking rods 10 disengage from the slot 12. At this time, the first connecting block 3 can be pulled out from the second connecting block 4, that is, the lid 2 is separated from the box body 1. When installing the lid 2, insert the two first connecting blocks 3 into the two second connecting blocks 4 respectively, and push the lid 2 backward. When the lid 2 drives the locking rods 10 and the second connecting rods 11 to slide inward, the first connecting block 3 can be pulled out from the second connecting block 4, thus separating the lid 2 from the box body 1. When the connecting block 4 contacts, the second connecting block 4 presses the locking rod 10 inward. The locking rod 10 drives the U-shaped plate 6 to slide forward through the short column 11 and the slot 9, thereby compressing the spring 15. When the first connecting block 3 is inserted into the innermost side of the second connecting block 4, so that the locking rod 10 is aligned with the slot 12, the U-shaped plate 6 slides backward under the elastic force of the spring 15, and then drives the locking rod 10 to slide outward through the short column 11 and the slot 9, locking it into the slot 12, thus fixing the first connecting block 3 and the second connecting block 4, that is, fixing the box cover 2 to the box body 1. This utility model connects the box cover 2 to the box body 1 by a snap-fit ​​method, which makes it convenient to install and remove the box cover 2 and facilitates maintenance.

[0025] As a technical optimization of this utility model, two symmetrically distributed springs 15 are provided between the U-shaped plate 6 and the inner wall of the mounting groove 5.

[0026] In this embodiment: by setting two symmetrically distributed springs 15 between the U-shaped plate 6 and the inner wall of the mounting groove 5, the spring force of the springs 15 can be used to drive the locking rod 10 to rebound.

[0027] As a technical optimization of this utility model, a sliding rod 7 is fixedly connected to the front end face of the U-shaped plate 6. The sliding rod 7 is slidably connected to the first connecting block 3. The front end of the sliding rod 7 extends to the outside of the first connecting block 3 and is fixedly connected to the first handle 8.

[0028] In this embodiment: by fixing a slide rod 7 to the front end face of the U-shaped plate 6, and extending the front end of the slide rod 7 to the outside of the first connecting block 3 and fixing a first handle 8 thereto, it is convenient to pull the U-shaped plate 6 from the outside through the first handle 8.

[0029] As a technical optimization of this utility model, the front end face of the box cover 2 is fixedly connected with two symmetrically distributed second handles 13.

[0030] In this embodiment, two symmetrically distributed second handles 13 are fixedly connected to the front end face of the lid 2 to facilitate the taking and putting away of the lid 2.

[0031] As a technical optimization of this utility model, the end of the lever 10 extending to the outside of the first connecting block 3 is inclined.

[0032] In this embodiment: by setting one end of the lever 10 extending outside the first connecting block 3 as a slope, it is easier to press the lever 10 inward when it comes into contact with the second connecting block 4.

[0033] As a technical optimization of this utility model, the cross-section of the lever 10 is rectangular.

[0034] In this embodiment, the cross-section of the lever 10 is set to a rectangle to prevent the lever 10 from rotating.

[0035] As a technical optimization of this utility model, a sealing ring 14 is provided on the rear end face of the box cover 2.

[0036] In this embodiment, a sealing ring 14 is provided on the rear end face of the lid 2 to facilitate good sealing between the lid 2 and the box body 1.

[0037] The working principle and usage process of this utility model are as follows: When disassembling the box cover 2, grasp the two second handles 13 with both hands, hook the first handle 8 with the index and middle fingers of both hands respectively, and pull the first handle 8 forward. The first handle 8 drives the sliding rod 7 to slide forward, which in turn drives the U-shaped plate 6 to slide forward. The U-shaped plate 6 drives the upper and lower locking rods 10 to slide inward through the slot 9 and the short column 11, so that the locking rods 10 disengage from the slot 12. At this time, the first connecting block 3 can be pulled out from the second connecting block 4, that is, the box cover 2 is separated from the box body 1. When installing the box cover 2, insert the two first connecting blocks 3 into the two second connecting blocks 4 respectively, and push the box cover 2 backward. When the box cover 2 drives the locking rods... When the first connecting block 3 contacts the second connecting block 4, the second connecting block 4 presses the locking rod 10 inward. The locking rod 10 drives the U-shaped plate 6 to slide forward through the short column 11 and the slot 9, thereby compressing the spring 15. When the first connecting block 3 is inserted into the innermost side of the second connecting block 4, so that the locking rod 10 is aligned with the slot 12, the U-shaped plate 6 slides backward under the elastic force of the spring 15, and then drives the locking rod 10 to slide outward through the short column 11 and the slot 9, and locks it into the slot 12, fixing the first connecting block 3 and the second connecting block 4, that is, fixing the box cover 2 and the box body 1. This utility model connects the box cover 2 and the box body 1 by snap-fit, which makes it convenient to install and remove the box cover 2 and facilitates maintenance.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
