[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments. Example

[0025] Reference Figure 1 , Figure 2 and Figure 7 This is the first embodiment of the present invention. This embodiment provides a waste heat recovery device for metal heat treatment. The waste heat recovery device for metal heat treatment includes a main body component and an installation component. The two cooperate with each other to provide sufficient working space for construction personnel during maintenance work, avoiding the problems of hand cuts and tools falling into the box and being difficult to remove.

[0026] Specifically, the main component 100 includes a housing 101 and a flue gas flange 102, with the flue gas flange 102 fixed to one side of the housing 101.

[0027] There are two flue gas flanges 102, one on each side of the housing 101. The flue gas flanges 102 allow the high-temperature flue gas to enter the inside of the housing 101 and then be discharged as low-temperature flue gas. The flange surface of the flue gas flange 102 is provided with grooves, which allow the rubber ring to be squeezed in the grooves during connection, ensuring the reliability of the seal.

[0028] Specifically, the installation component 200 is located on one side of the housing 101 and includes a movable component 201, a movable support component 202, a lifting component 203, and a limiting component 204. The movable component 201 is located on one side of the housing 101, the movable support component 202 is located outside the movable component 201, the lifting component 203 is located on top of the movable support component 202, and the limiting component 204 is located on one side of the lifting component 203.

[0029] By setting up movable part 201, construction workers have a larger working space during maintenance work, avoiding the safety hazard of being cut on their arms due to poor visibility caused by a crowded working space, thus improving work efficiency. Example

[0030] Reference Figure 2 Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] Specifically, the movable component 201 includes a slide rail 201a, a push-pull module 201b, and a fluid circulation pipe 201c. The slide rail 201a is fixed to the inside of the housing 101, the push-pull module 201b is movable inside the slide rail 201a, and the fluid circulation pipe 201c is fixed to the inside of the push-pull module 201b.

[0032] There are two slide rails 201a, both located inside the housing 101. The fluid circulation pipe 201c is fixed in the hole provided by the push-pull module 201b. The push-pull module 201b moves horizontally along the slide rail 201a, and moves the fluid circulation pipe 201c to the outside of the housing 101, thereby maximizing the working space. The vertical plate on one side of the push-pull module 201b and the opening on one side of the housing 101 are fixed with bolts during operation. Rubber is placed on the inner side of the contact surface between the vertical plate on one side of the push-pull module 201b and the opening on one side of the housing 101, making its sealing more reliable.

[0033] Specifically, the movable support component 202 includes a chassis 202a, casters 202b, and a drive motor 202c. The chassis 202a is movable on one side of the housing 101, the casters 202b are rotatably connected to the bottom of the chassis 202a, and the drive motor 202c is fixed to one side of the chassis 202a.

[0034] There are four casters 202b, all of which are installed on the chassis 202a. The casters 202b can lock the tires themselves to restrict their movement. A protruding frame is provided on one side of the chassis 202a. The size of the frame is consistent with the gap on the inside of the bottom support leg of the box 101, so that the chassis 202a will not shake at will.

[0035] Specifically, the movable support component 202 also includes a threaded rod 202d and a movable block 202e. One end of the threaded rod 202d is rotatably connected to one side of the chassis 202a, and the other end of the threaded rod 202d is fixed to the output end of the drive motor 202c. The movable block 202e is movable to the outside of the threaded rod 202d and is movably fixed to the inside of the push-pull module 201b.

[0036] By starting the drive motor 202c, the drive motor 202c drives the threaded rod 202d. The rotation of the threaded rod 202d causes the movable block 202e, which moves on its outer side, to move. The movable block 202e drives the push-pull module 201b, which is movably connected to it, to move. This allows the fluid circulation pipe 201c inside the housing 101 to be smoothly pulled out to the outside of the housing 101 during maintenance, enabling construction personnel to better observe the fault location and improving work efficiency.

[0037] Specifically, the lifting component 203 includes a base plate 203a, a slide rail square tube 203b, and a top support gear rack 203c. The base plate 203a is fixed to the top of the chassis 202a, the slide rail square tube 203b is fixed to the top of the base plate 203a, and the top support gear rack 203c is movable inside the slide rail square tube 203b.

[0038] There are two slide rail square tubes 203b and top support gear racks 203c. The slide rail square tube 203b is provided with a slide rail on the inner side, so that the top support gear rack 203c can move horizontally along the outer side of the slide rail. Example

[0039] Reference Figures 5-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0040] Specifically, the lifting component 203 also includes an extension slide rail 203d, a transmission rod 203e, a first gear 203f, and a quick throttle 203g. The extension slide rail 203d is fixed to the top of the top support gear rack 203c. The transmission rod 203e is rotatably connected to one side of the base plate 203a. The first gear 203f is fixed to the outside of the transmission rod 203e and meshes with the top support gear rack 203c. The quick throttle 203g is fixed to the end of the transmission rod 203e.

[0041] There are two extension slide rails 203d. The movement of the top support gear rack 203c drives the extension slide rails 203d to move. The extension slide rails 203d are designed so that when the push-pull module 201b moves to the outside of the box, it can move inside the extension slide rails 203d, thus achieving a smooth movement function and avoiding the problem of the entire equipment tilting due to weight imbalance caused by the movement of the push-pull module 201b. There are two first gears 203f. By rotating the quick turn handle 203g, the quick turn handle 203g drives the transmission rod 203e, the transmission rod 203e drives the first gears 203f, and the first gears 203f drive the top support gear rack 203c to move.

[0042] Specifically, the limiting component 204 includes a second gear 204a, a housing 204b, a wedge-shaped limiting rod 204c, a handle 204d, a baffle 204e, and a spring 204f. The second gear 204a is fixed to the outside of the transmission rod 203e, the housing 204b is fixed to one side of the base plate 203a, one end of the wedge-shaped limiting rod 204c passes through the housing 204b and meshes with the second gear 204a, the other end of the wedge-shaped limiting rod 204c is fixed to the end of the handle 204d, the baffle 204e is fixed to the outside of the wedge-shaped limiting rod 204c, and the end of the spring 204f is fixed to one side of the baffle 204e.

[0043] The end of the wedge-shaped limiting rod 204c is wedge-shaped, allowing the second gear 204a to rotate in one direction. When the second gear 204a needs to rotate in the opposite direction, the handle 204d is pulled. The handle 204d causes the wedge-shaped limiting rod 204c to no longer mesh with the second gear 204a. The wedge-shaped limiting rod 204c drives the baffle 204e, which in turn moves to compress the spring 204f. When the handle 204d is released, the spring 204f pushes the baffle 204e, which in turn causes the end of the wedge-shaped limiting rod 204c to mesh with the second gear 204a, thus achieving the limiting function.

[0044] In use, first move the chassis 202a into the gap inside the bottom support legs of the housing 101, then lock the caster 202b. Next, loosen the screws connecting the vertical plate on one side of the push-pull module 201b to the opening on one side of the housing 101. Then, movably fix the movable block 202e inside the push-pull module 201b. Start the drive motor 202c. When the movable block 202e moves the push-pull module 201b a certain distance, pull the handle 204d to disengage the wedge-shaped limit rod 204c from the second gear 204a. Turn the quick-release handle 203g to rotate the transmission rod 203e, which in turn drives the first gear 203f. 203f drives the top support gear rack 203c to move. When the top support gear rack 203c drives the extension slide rail 203d to move to the required height, the handle 204d is released so that the wedge-shaped limit rod 204c meshes with the second gear 204a. The second gear 204a restricts the transmission rod 203e, thus achieving the ability to limit and lock. Then, the motor is started so that the push-pull module 201b can be moved to the required position to complete the maintenance work. The movable block 202e is no longer connected to the push-pull module 201b. After the screws at the connection between the vertical plate on one side of the push-pull module 201b and the opening on one side of the box 101 are tightened, the chassis 202a can be moved to the storage position.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
