A first telescopic spring 21 is symmetrically fixedly connected between one side of the T-shaped rod 210 and the fixing box 209 1. The tension generated by the first telescopic spring 211 allows the plug block 212 to quickly fall off the second curved plate 205, thereby improving the disassembly efficiency of the heat exchanger 102. The first curved plate 204 and the second curved plate 205 are rotatably connected, and the first curved plate 204 and the second curved plate 205 are engaged and connected at one end away from the connection, and a positioning rod 213 is fixedly connected to one side of the extrusion block 208, and one end of the positioning rod 213 penetrates the installation box 206 and is slidably connected to the second curved plate 205.

The movement of the heat exchanger 102 drives the movement of the second connecting plate 307, and the movement of the second connecting plate 307 drives the wheel 310 to roll inside the slide rail 308, thereby greatly improving the stability of the heat exchanger 102 during disassembly and movement, which brings convenience to the staff when using it.

[0028] Working principle: Before using this waste heat boiler that is easy to clean scale, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, by merging the heat exchanger 102 and the boiler tank body 101, the fixing ring 201 and the connecting ring 202 are engaged, and by inserting a plurality of positioning blocks 203 into the connecting ring 202, the first arc plate 204 and the second arc plate 205 are rotatably sleeved in the fixing ring 201. At this time, the first arc plate 204 and the second arc plate 205 are engaged and connected at one end, and then the extrusion block 208 is driven to move by rotating the screw 207. The movement of the extrusion block 208 squeezes the T-bar 210, and the T-bar 210 is squeezed and moved, thereby driving the insert block 212 to be engaged and fixed between the second arc plate 205, thereby achieving the effect of quickly installing and removing the heat exchanger 102. Compared with the method of fixing with multiple sets of bolts in the prior art, it is more convenient, improves the overall disassembly efficiency of the device, and facilitates the staff to clean the scaling on the inner wall of the boiler tank body 101 later, which brings convenience to the staff when using it. The movement of the T-shaped rod 210 causes the first telescopic spring 211 to stretch. When the extrusion block 208 no longer squeezes the T-shaped rod 210, the tension generated by the first telescopic spring 211 causes the plug block 212 to quickly fall off the second arc plate 205, thereby improving the disassembly efficiency of the heat exchanger 102. The movement of the extrusion block 208 drives the positioning rod 213 to insert and limit the second arc plate 205, thereby making the first arc plate 204 and the second arc plate 205 more stably fixed. The plug rod 215 drives the retaining ring 216 to squeeze the second telescopic spring 217. The plug rod 215 is released, and the second telescopic spring 217 is reset, so that the plug rod 215 is engaged and fixed with the first arc plate 204 and the second arc plate 205, thereby further improving the fixing stability between the first arc plate 204 and the second arc plate 205, and reducing the probability of accidental falling off of the heat exchanger 102.

[0029] By starting the forward and reverse motor 306 to drive the threaded rod 304 to rotate, the rotation of the threaded rod 304 drives the movement of the first connecting plate 305, and the movement of the first connecting plate 305 drives the heat exchanger 102 to separate from the boiler tank body 101, thereby achieving the effect of quickly disassembling the heat exchanger 102, which brings convenience to the staff for subsequent inspection and maintenance of the heat exchanger 102 and the boiler tank body 101. The movement of the heat exchanger 102 drives the movement of the second connecting plate 307, and the movement of the second connecting plate 307 drives the rotating wheel 310 to roll inside the slide rail 308, thereby greatly improving the stability of the heat exchanger 102 during disassembly and movement, which brings convenience to the staff when using it.
