Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1-Figure 4 , a heat recovery device shown in the figure includes an inner liner box 102 arranged in a furnace body 101, two opposite side walls of the inner liner box 102 are provided with U-shaped handles 103, and also includes a fixing mechanism arranged on the furnace body 101 for fixing the inner liner box 102;

[0023] The fixing mechanism includes two fixing holes 201 provided on two inner walls opposite to each other of the furnace body 101. The two fixing holes 201 on the same side are symmetrically arranged. The liner box 102 is provided with two mounting holes 202 on both sides close to the furnace body 101. A fixing block 203 is slidably connected in the two mounting holes 202 on the same side. The two fixing blocks 203 are matched with the fixing holes 201. A driving mechanism for driving the two fixing blocks 203 is provided on the U-shaped handle 103.

[0024] It should be noted here that: through the setting of the fixing mechanism, under the action of the driving mechanism, while ensuring the firmness of the lining box 102, under the impact of the fixing block 203, it is used to warn the operator during installation, and there is no need to observe the installation of the lining box 102, thereby improving the accuracy and speed of the installation of the lining box 102, and the overall fixing mechanism is connected to the lining box 102, thereby avoiding the risk of loss.

[0025] It is worth noting that: the utility model is an improvement on the prior art. For the specific structure and working principle of the furnace body 101, please refer to the authorization publication number CN220017368U, a heat recovery device, which will not be elaborated here.

[0026] See also Figure 3, the two fixing blocks 203 shown in the figure are provided with inclined surfaces 204 on one side close to the furnace body 101, and the two inclined surfaces 204 slide on the inner wall of the furnace body 101;

[0027] It should be noted here that: through the setting of the inclined surface 204, when the fixing block 203 on the liner box 102 abuts against the side wall of the furnace body 101, the interaction force of the inclined surface 204 and the guiding action of the guide assembly will push the fixing block 203 to retract into the mounting hole 202.

[0028] See also Figure 3 The U-shaped handle 103 shown in the figure is provided with a guide assembly for guiding the movement of the two fixed blocks 203, and the guide assembly includes a guide groove 301 provided on the U-shaped handle 103, and a guide plate 302 is slidably connected to the guide groove 301, and one end of the guide plate 302 penetrates the liner box 102 and is connected to the fixed block 203, and a guide tube 303 is fixedly connected to the bottom wall of the guide groove 301, and a guide rod 304 is slidably connected to the guide tube 303, and one end of the guide rod 304 is connected to the guide plate 302, and an extrusion assembly for extruding the fixed block 203 is provided on the guide tube 303;

[0029] It should be noted here that: by setting the guide component, a guiding and limiting function is provided for the movement of the fixed block 203.

[0030] See also Figure 3 The extrusion assembly shown in the figure includes an extrusion plate 401 slidably connected in the guide tube 303, the other end of the guide rod 304 is connected to the extrusion plate 401, a spring 402 is provided on the other side of the extrusion plate 401, and the other end of the spring 402 is connected to the bottom wall of the guide tube 303;

[0031] It should be noted that: through the arrangement of the extrusion assembly, when the fixing block 203 is matched with the fixing hole 201 , the fixing block 203 is pushed into the fixing hole 201 under the elastic action of the extrusion assembly and abuts against the bottom wall of the fixing hole 201 .

[0032] Working principle: When the liner box 102 needs to be installed, first, under the guidance of the guide bar and the guide groove, the liner box 102 is inserted into the furnace body 101. When the fixing block 203 on the liner box 102 abuts against the side wall of the furnace body 101, the fixing block 203 is pushed to shrink into the installation hole 202 under the interaction force of the inclined surface 204 and the guiding action of the guide component. As the liner box 102 is continuously pushed, when the fixing block 203 is combined with the fixing hole 201, the inner liner box 102 is squeezed. Under the elastic action of the assembly, the fixing block 203 is pushed to move into the fixing hole 201 and abut against the bottom wall of the fixing hole 201, so that the inner liner box 102 is installed and fixed under the abutting action of the fixing block 203, and when the fixing block 203 abuts against the bottom wall of the fixing hole 201, it will collide with the bottom wall of the fixing hole 201, so that a sound is generated under the impact, which is used to warn the operator that the inner liner box 102 is installed in place and does not need to be pushed anymore;

[0033] When the liner box 102 needs to be disassembled, under the action of the driving mechanism, the two fixing blocks 203 are disengaged from the fixing holes 201 and retracted into the mounting holes 202, thereby releasing the fixing effect on the liner box 102, making it easy to remove the liner box 102 from the furnace body 101. The operation is simple and the implementation is convenient. There is no need to observe the installation of the liner box 102, and the overall fixing mechanism is connected to the liner box 102 to avoid the risk of loss.

[0034] Example 2

[0035] See also Figure 2 and Figure 3 , this embodiment further explains Example 1, the driving mechanism in the figure includes a driving plate 501 slidably connected in the U-shaped handle 103, a T-shaped rod 502 is fixedly connected to the side of the driving plate 501 away from the liner box 102, and driving grooves 503 are opened on the two opposite side walls of the U-shaped handle 103, and the two driving grooves 503 are connected to the guide groove 301, and the two ends of the driving plate 501 slide in the driving grooves 503 and are connected to the guide plate 302;

[0036] It should be noted here that: through the setting of the driving mechanism, when the inner lining box 102 needs to be disassembled, when the inner lining box 102 is pulled by the U-shaped handle 103, the palm part is against the side wall of the U-shaped handle 103, so that two fingers clamp the T-shaped rod 502, and pull the T-shaped rod 502 to drive the driving plate 501 to move. When the driving plate 501 moves, it will drive the fixing block 203 out of the fixing hole 201, thereby releasing the fixation of the inner lining box 102. At this time, the inner lining box 102 can be moved out from the inside of the furnace body 101 by pulling it.
