[0002] In modern industrial production activities, a large amount of coal and other fuels often need to be burned. For example, in the metallurgical industry, these fuels will generate a large amount of heat after combustion.

At this time, the sealing operation of the heat exchange plate 201 is completed. When in the connected state, the inner side of the heat exchange plate 201 is a hollow structure, and the heat exchange plate 201 is an arched structure as a whole, which is convenient for the liquid to flow inside the heat exchange plate 201. The openings on the sides of the upper and lower liquid separator blocks 301 are used as the inlet and outlet of the heat exchange liquid respectively, and the heat exchange liquid is pumped into the heat exchange plate 201 through an external water pump, so that the heat exchange liquid flows inside the heat exchange plate 201 through the liquid separator block 301, thereby realizing heat exchange. Through the arrangement of the liquid separator block 301, the heat exchange plate 201 can be independently disassembled and assembled, which is convenient for maintenance. The disassembly and assembly of the heat exchange plate 201 can be controlled by the squeezing rods 306 on both sides of the heat exchange box 1, and in order to fix the position of the squeezing rod 306, a card groove 701 is provided on the side of the squeezing rod 306. When the squeezing rod 306 is pressed to When the inner side of the mounting plate 203 is installed, the slot 701 on the side of the extrusion rod 306 will be engaged with the end of the positioning block 702 on the side. At this time, the extrusion rod 306 will maintain the pushing state for the liquid separator block 301, thereby maintaining the sealing state between the heat exchange plate 201 and the liquid separator block 301, thereby avoiding the leakage of the heat exchange liquid. When the engagement needs to be released, the user can rotate the rotating block 705 in the middle of the mounting plate 203, and the sliding column 706 on the bottom side of the rotating block 705 slides in the horizontal groove 704 on the positioning block 702, so that the positioning block 702 will be pushed to one side, thereby releasing the engagement state between the positioning block 702 and the extrusion rod. At this time, the pushing rod is reset under the push of the first spring 308, and the liquid separator block 301 and the heat exchange plate 201 are sealed. 01 is separated for easy operation. A motor 401 is installed on the side of the heat exchange box 1. The rotation of the drive shaft 403 can be controlled by intelligently controlling the electrical connection between the motor 401 and the external power supply. When the drive shaft 403 rotates, the multiple gears 404 arranged on the drive shaft 403 will drive the cleaning paddle 402 arranged on the side of the heat exchange plate 201 to rotate through the tooth groove 406. A cleaning paddle 402 is rotated on the rotating shaft blocks 405 on both sides of the heat exchange plate 201. The cleaning paddle 402 is pushed by the contact ring 407 and the third spring 408 to tightly contact the side of the heat exchange plate 201. With the rotation of the cleaning paddle 402, the impurities on the side of the heat exchange plate 201 can be scraped off in time to ensure the heat exchange effect of the heat exchange plate 201.To realize intelligent cleaning of the heat exchange plate 201 when the heat exchange effect decreases, according to different flue gas heat exchange requirements, the user can connect multiple heat exchange boxes 1 in series to utilize the waste heat of the flue gas. An air inlet pipe 601 and an exhaust pipe 602 are respectively provided at both ends of the heat exchange box 1. A filter plate 604 is provided in the middle of the exhaust pipe 602 to filter the exhausted flue gas. Combined with the cleaning effect of the cleaning paddle 402 on the heat exchange plate 201, the heat in the flue gas is fully utilized while avoiding direct discharge of impurities in the flue gas. When multiple heat exchange boxes 1 need to be connected in series, the user needs to connect the heat exchange boxes 1 The ends of the exhaust pipe 602 are connected to each other so that the exhaust pipe 602 conflicts with the end of the intake pipe 601. Then, the user needs to pull the control rod 603 on the side of the intake pipe 601 to make the locking block 610 on the side of the control rod 603 disengage from the positioning groove 609 provided on the intake pipe 601, and then rotate the control rod 603 to make the fastening sleeve 606 rotate to one side. As the fastening sleeve 606 rotates, since the edge portion of the exhaust pipe 602 is provided with a bevel structure, the extrusion protrusion 607 at the end of the fastening sleeve 606 will push the exhaust pipe 602 into the inner part of the intake pipe 601 through the bevel protrusion at the end of the exhaust pipe 602. Push sideways until the end of the exhaust pipe 602 is tightly in contact with the second sealing gasket 605 inside the intake pipe 601 to ensure the air tightness of the connection, and finally release the control rod 603 so that the locking block 610 on the side of the control rod 603 is re-engaged with the other positioning groove 609 to fix the current connection state, and the series use of the two heat exchange boxes 1 can be completed to improve the flexibility of the device. After the internal arrangement of the heat exchange box 1 is completed, a sealing plate 502 is provided on the top side of the heat exchange box 1, and the sealing plate 502 is connected to the screw holes 503 on the heat exchange box 1 through the fastening bolts 503 set at the four corners. 04 is fixed. When the threaded fixing of the fastening bolt 503 is completed, the sealing plate 502 will contact and seal with the top side of the heat exchange box 1. During this process, the sealing plate 502 will simultaneously push the extended part of the extrusion rod 306, thereby realizing the connection state between the liquid separation block 301 and the heat exchange plate 201, further ensuring the sealing of the flow of the heat exchange fluid. When the sealing plate 502 is opened, due to the clamping effect of the positioning clamp 702, the heat exchange plate 201 and the liquid separation block 301 will continue to maintain a connection state. The user can perform disassembly and assembly operations as needed, thereby improving the convenience of the device during maintenance. ,
