The two arc-shaped guide rails are fixedly installed on the upper and lower side walls of the valve groove respectively, the upper and lower side walls of the closing door are slidably installed in the two guide rails respectively, and the push block is fixedly installed in the middle of the end of the closing door.

[0012] In one embodiment, the water storage component includes a support frame, a water tank, a water inlet pipe and a water supply pipe. The support frame is placed on the ground, the water tank is installed on the top of the support frame, the water inlet pipe and the water supply pipe are respectively installed on the two side walls of the water tank, and the water supply pipe is connected to the water inlet pipe.

[0013] In one embodiment, multiple cleaning knocking components are all mounted in the cooling section, and each cleaning knocking component includes an expansion buoyancy component, multiple knocking components and multiple impact components. The expansion buoyancy component is mounted on the middle side wall of the cooling section, and the expansion buoyancy component includes a brush, an elastic expansion block with a ring-shaped opening and an elastic buoyancy plate with a ring-shaped opening. One end of the brush is abutted and mounted on the middle side wall of the cooling section, the side wall of the elastic expansion block is fixedly connected to the other end of the brush, and the elastic buoyancy plate is installed on the bottom of the elastic expansion block.

[0014] In one embodiment, multiple knocking members and multiple impact members are all installed on the side wall of the elastic expansion block, and the multiple knocking members and the multiple impact members are staggered. Each knocking member includes a connecting long rope and a metal hollow ball. The upper end of the connecting long rope is fixedly connected to the side wall of the elastic expansion block, and the metal hollow ball is fixedly connected to the lower end of the connecting long rope. Each impact member includes a connecting short rope and a small hollow ball. The upper end of the connecting short rope is fixedly connected to the side wall of the elastic expansion block and the small hollow ball is fixedly connected to the lower end of the connecting short rope.

[0015] The present invention provides an elastic scraper plate. After the filter is clogged, the pressure on the filter increases, the filter will move upward, and the scraper follows the filter upward. The filter will squeeze the four telescopic parts to move upward. The four telescopic parts are compressed, and the elastic scraper plate of the scraper will break away from the abutment of the block. The driving fan will rotate under the blowing of upward hot air, the rotating rod follows the driving fan to rotate, and the elastic scraper plate follows the rotating rod to rotate, which is used to scrape off the fixed fuel particles clogged on the top of the filter. The fixed fuel particles clogged on the top of the filter move toward the end of the elastic scraper plate away from the rotating rod under the action of centrifugal force. When the elastic scraper plate rotates and approaches the pushing block, the elastic scraper plate will squeeze the pushing block to open in the direction of rotation of the elastic scraper plate, and the pushing block squeezes the closed door to open a part of the opening. The fixed fuel particles scraped by the elastic scraper plate will enter the collection pipe through the part of the opening under the action of centrifugal force. Due to the blockage of the filter screen, the fixed fuel particles will not be sucked back to the top of the filter screen by the fan and the opening of the closed door is not large. When the closed door moves to the other end of the guide rail, the elastic scraper plate will bend to enable the elastic scraper plate to separate from the pushing block. After the elastic scraper plate separates from the abutment of the pushing block, it continues to scrape the fixed fuel particles blocked on the top of the filter screen. The pushing block is After being pushed away by the elastic scraper plate, the other end of the closed door is connected to a restoring spring, which restores after the pushing block is separated from the push of the elastic scraper plate, causing the closed door to close the upper end opening of the collecting tube, preventing the fixed fuel particles from flowing back to the bottom of the filter screen. This is repeated to unclog the filter screen, and at the same time, the clogged fixed fuel particles can fall along the collecting tube into the combustion tank, where they continue to act as fuel, thereby increasing the combustion material for the boiler and saving resources. At the same time, when the boiler is working, the boiler combustion will generate vibration, which can accelerate the falling of the fixed fuel particles in the collecting tube, thereby causing them to fall into the combustion tank and continue to burn, thereby accelerating the temperature rise of the water.

[0016] By setting up an elastic buoyancy plate, when the water tank is filled with water, the elastic buoyancy plate will float on the water surface, and the elastic buoyancy plate moves upward along with the water surface, so that the brush can follow the height of the water surface in the water tank to clean the surface of the cooling section, thereby preventing impurities from being adsorbed on the surface of the cooling section, thereby reducing the heat transfer efficiency of the cooling section.

[0017] By installing an elastic expansion block, heat within the cooling section is transferred to the cooling section, which in turn transfers the heat to the water in the water tank, preheating the water and making full use of resources. After the heat is transferred from the cooling section to the water in the water tank, the water in the water tank heats up, and the elastic expansion block expands due to the heat. This expansion squeezes the brush closer to the cooling section, allowing the brush to adhere closely to the cooling section, thereby more thoroughly removing impurities adhering to the surface of the cooling section, thereby improving heat transfer efficiency and reducing energy waste.

[0018] By providing the metal hollow balls and the small hollow balls, when the water tank is filled with water, the elastic buoyancy plate will float on the water surface and move upward with the water surface. When the water tank is filled with water, the water surface inside the water tank shakes, causing the metal hollow balls floating on the water surface to shake with the water surface. The metal hollow balls can then strike the surface of the cooling section, causing impurities attached to the inner and outer surfaces of the cooling section to fall off, thereby improving heat transfer efficiency and reducing energy waste. The metal hollow balls are relatively large, and when striking the cooling section, they will not contact the elastic expansion block and the elastic buoyancy plate. When the water tank is filled with water, the water surface inside the water tank shakes, causing the small hollow balls floating on the water surface to shake with the water surface. The small hollow balls can then strike the elastic expansion block, causing impurities adsorbed on the brush to fall off. After the water temperature inside the water tank rises, the water inside the water tank boils and shakes, causing the metal hollow balls to hit the surface of the cooling section, thereby causing impurities attached to the inner and outer surfaces of the cooling section to fall off, thereby improving heat transfer efficiency and reducing energy waste; and then causing the small hollow balls floating on the water surface to shake with the water surface, and then the small hollow balls can hit the elastic expansion block, thereby causing impurities adsorbed on the brush to fall off, preventing the brush from being unable to clean the surface of the cooling section.

[0019] The present invention has an ingenious structure and can make good and full use of resources. It can not only reduce energy waste, but also prevent the filter from being blocked, thereby extending the service life of the filter and reducing maintenance and replacement costs. At the same time, the present invention can also make good use of waste heat to preheat water, prevent impurities from adhering to the inner and outer surfaces of the pipe, thereby reducing heat transfer.

[0044] 2. After the filter 211 is clogged, the pressure on the filter 211 increases, the filter 211 will move upward, and the scraper 22 will follow the filter 211 to move upward. The filter 211 will squeeze the four telescopic members 210 to move upward. The four telescopic members 210 are compressed, and the elastic scraper plate 222 of the scraper 22 will break away from the abutment of the block 135. The driving fan 223 will rotate clockwise under the blowing of the upward hot air, and the rotating rod 220 will rotate along with the driving fan 223. The elastic scraper plate 222 follows the rotating rod 220 to rotate, which is used to scrape off the fixed fuel particles clogged on the top of the filter 211. Under the action of centrifugal force, the fixed fuel particles clogged on the top of the filter 211 move toward the end of the elastic scraper plate 222 away from the rotating rod 220. When the elastic scraper plate 222 rotates and approaches the pushing block 232, the elastic scraper plate 222 will squeeze the pushing block 232 to open in the direction of rotation of the elastic scraper plate 222, and the pushing block 232 squeezes the closing door 231 to open a part of the opening. The fixed fuel particles scraped by the elastic scraper plate 222 will enter the collection pipe 14 through the part of the opening under the action of centrifugal force. Because the filter screen 211 is blocked, the fixed fuel particles will not be sucked back to the top of the filter screen 211 by the fan and the opening of the closing door 231 is not large. When the closing door 231 moves to the other end of the guide rail 230, the elastic scraper plate 222 will bend so that the elastic scraper plate 222 can break away from the pushing block 232. After the elastic scraper plate 222 breaks away from the contact with the pushing block 232, it continues to scrape the fixed fuel particles blocked on the top of the filter screen 211. The fuel particles are prevented from flowing back to the bottom of the filter screen 211 by the closing door 231. This is repeated to clear the filter screen 211, and at the same time, the clogged fixed fuel particles can fall along the collecting pipe 14 into the combustion tank 130, where they continue to act as fuel, thereby increasing the combustion material for the boiler and saving resources. At the same time, when the boiler is working, the boiler combustion will generate vibration, which can accelerate the falling of the fixed fuel particles in the collecting pipe 14, thereby causing them to fall into the combustion tank 130 and continue to burn, thereby accelerating the temperature rise of the water. After the filter screen 211 is unblocked, the pressure on the filter screen 211 decreases, and the filter screen 211 moves downward until the elastic scraping plate 222 abuts against the pushing block 232, and the elastic scraping plate 222 stops rotating.

[0045] 3. The hot air transferred to the multiple smoke pipes 123 passes through the exhaust pipe 13 and the high-temperature section 310 and then enters the cooling section 311. The hot air in the cooling section 311 can preheat the water in the water tank 321, preventing energy waste. When the water tank 321 is filled with water, the elastic buoyancy plate 412 will float on the water surface and move upward with the water surface, allowing the brush 410 to follow the height of the water surface in the water tank 321 to clean the surface of the cooling section 311, preventing impurities from accumulating on the surface of the cooling section 311 and reducing the heat transfer efficiency of the cooling section 311.

[0046] 4. The heat within the cooling section 311 is transferred to the cooling section 311, which in turn transfers the heat to the water within the water tank 321, preheating the water therein and making full use of resources. After the heat within the cooling section 311 is transferred to the water within the water tank 321, the water within the water tank 321 heats up, causing the elastic expansion block 411 to expand due to the heat. This expansion of the elastic expansion block 411 presses the brush 410 toward the cooling section 311, allowing the brush 410 to adhere closely to the cooling section 311, thereby more thoroughly removing impurities adhering to the surface of the cooling section 311. This improves heat transfer efficiency and reduces energy waste.

[0047] 5. When the water tank 321 is filled with water, the elastic buoyancy plate 412 will float on the water surface, and the elastic buoyancy plate 412 will move upward along with the water surface. When the water tank 321 is filled with water, the water surface inside the water tank 321 will shake, so that the metal hollow balls 421 floating on the water surface can shake along with the water surface, and then the metal hollow balls 421 can knock on the surface of the cooling section 311, so that impurities attached to the inner and outer surfaces of the cooling section 311 fall off, thereby improving the heat transfer efficiency and reducing energy waste. The metal hollow ball 421 is relatively large in size. When hitting the cooling section 311, the metal hollow ball 421 will not contact the elastic expansion block 411 and the elastic buoyancy plate 412; when the water tank 321 is filled with water, the water surface inside the water tank 321 shakes, so that the small hollow ball 431 floating on the water surface can shake with the water surface, and then the small hollow ball 431 can hit the elastic expansion block 411, thereby causing the impurities adsorbed on the brush 410 to fall off. After the water temperature inside the water tank 321 rises, the water inside the water tank 321 boils and shakes, so that the metal hollow balls 421 can knock on the surface of the cooling section 311, so that impurities attached to the inner and outer surfaces of the cooling section 311 fall off, thereby improving the heat transfer efficiency and reducing energy waste; and the small hollow balls 431 floating on the water surface can shake with the water surface, and the small hollow balls 431 can hit the elastic expansion block 411, so that impurities adsorbed on the brush 410 fall off, preventing the brush 410 from being unable to clean the surface of the cooling section 311.

[0048] The present invention is provided with an elastic scraper plate 222. After the filter screen 211 is blocked, the pressure on the filter screen 211 increases, the filter screen 211 will move upward, and the scraper 22 will follow the filter screen 211 to move upward. The filter screen 211 will squeeze the four telescopic members 210 to move upward. The four telescopic members 210 are compressed, and the elastic scraper plate 222 of the scraper 22 will break away from the abutment of the block 135. The driving fan 223 will rotate under the blowing of the upward hot air, and the rotating rod 220 will rotate along with the driving fan 223. The elastic scraper plate 222 follows the rotating rod 220 to rotate, and is used to scrape off the fixed fuel particles blocked on the top of the filter screen 211. The fixed fuel particles blocked on the top of the filter screen 211 move toward the end of the elastic scraper plate 222 away from the rotating rod 220 under the action of centrifugal force. When the elastic scraper plate 222 rotates and approaches the pushing block 232, the elastic scraper plate 222 will squeeze the pushing block 232 to open in the direction of rotation of the elastic scraper plate 222, and the pushing block 232 squeezes the closing door 231 to open a part of the opening. The fixed fuel particles scraped by the elastic scraper plate 222 will enter the collection pipe 14 through the part of the opening under the action of centrifugal force. Because the filter screen 211 is blocked, the fixed fuel particles will not be sucked back to the top of the filter screen 211 by the fan and the opening of the closing door 231 is not large. When the closing door 231 moves to the other end of the guide rail 230, the elastic scraper plate 222 will bend so that the elastic scraper plate 222 can break away from the pushing block 232. After the elastic scraper plate 222 breaks away from the contact with the pushing block 232, it continues to scrape the fixed fuel particles blocked on the top of the filter screen 211. The fuel particles, after the push block 232 is separated from the push of the elastic scraper plate 222, the other end of the closed door 231 is connected to a restoring spring, and the restoring spring is restored after the push block 232 is separated from the push of the elastic scraper plate 222, so that the closed door 231 closes the upper end opening of the collection pipe 14, preventing the fixed fuel particles from flowing back to the bottom of the filter screen 211. This is repeated to clear the filter screen 211, and at the same time, the blocked fixed fuel particles can fall along the collection pipe 14 into the combustion tank 130, and continue to act as fuel in the combustion tank 130, thereby increasing the combustion material for the boiler and saving resources. At the same time, when the boiler is working, the boiler combustion will generate vibration, which can accelerate the falling of the fixed fuel particles in the collection pipe 14, and then make them fall into the combustion tank 130 to continue burning, thereby accelerating the temperature rise of the water.

[0049] By setting up the elastic buoyancy plate 412, when the water tank 321 is filled with water, the elastic buoyancy plate 412 will float on the water surface, and the elastic buoyancy plate 412 moves upward along with the water surface, so that the brush 410 can follow the height of the water surface in the water tank 321 to clean the surface of the cooling section 311, thereby preventing impurities from being adsorbed on the surface of the cooling section 311, thereby reducing the heat transfer efficiency of the cooling section 311.

[0050] By providing the elastic expansion block 411, heat within the cooling section 311 is transferred to the cooling section 311. The cooling section 311 then transfers the heat to the water in the water tank 321, thereby preheating the water in the water tank 321 and making full use of resources. After the heat from the cooling section 311 is transferred to the water in the water tank 321, the water in the water tank 321 heats up, and the elastic expansion block 411 expands due to the heat. The expansion of the elastic expansion block 411 presses the brush 410 toward the cooling section 311, allowing the brush 410 to adhere closely to the cooling section 311, thereby more thoroughly removing impurities adhering to the surface of the cooling section 311, thereby improving heat transfer efficiency and reducing energy waste.

[0051] By setting the metal hollow balls 421 and the small hollow balls 431, when the water tank 321 is filled with water, the elastic buoyancy plate 412 will float on the water surface, and the elastic buoyancy plate 412 will move upward along with the water surface. When the water tank 321 is filled with water, the water surface inside the water tank 321 will shake, so that the metal hollow balls 421 floating on the water surface can shake along with the water surface, and then the metal hollow balls 421 can knock on the surface of the cooling section 311, so that impurities attached to the inner and outer surfaces of the cooling section 311 fall off, thereby improving the heat transfer efficiency and reducing energy waste. The metal hollow ball 421 is relatively large in size. When hitting the cooling section 311, the metal hollow ball 421 will not contact the elastic expansion block 411 and the elastic buoyancy plate 412; when the water tank 321 is filled with water, the water surface inside the water tank 321 shakes, so that the small hollow ball 431 floating on the water surface can shake with the water surface, and then the small hollow ball 431 can hit the elastic expansion block 411, thereby causing the impurities adsorbed on the brush 410 to fall off. After the water temperature inside the water tank 321 rises, the water inside the water tank 321 boils and shakes, so that the metal hollow balls 421 can knock on the surface of the cooling section 311, so that impurities attached to the inner and outer surfaces of the cooling section 311 fall off, thereby improving the heat transfer efficiency and reducing energy waste; and the small hollow balls 431 floating on the water surface can shake with the water surface, and the small hollow balls 431 can hit the elastic expansion block 411, so that impurities adsorbed on the brush 410 fall off, preventing the brush 410 from being unable to clean the surface of the cooling section 311.

[0052] The present invention has an ingenious structure and can make good and full use of resources. It can not only reduce energy waste, but also prevent the filter 211 from being blocked, thereby extending the service life of the filter 211 and reducing maintenance and replacement costs. At the same time, the present invention can also make good use of waste heat to preheat water, prevent impurities from adhering to the inner and outer surfaces of the pipe, and thus reduce heat transfer.

[0054] The above-described embodiments merely represent several embodiments of the present invention.
