The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of the present invention will now be described.

[0028] An energy-saving, regenerative kiln flue gas waste heat recovery and utilization device, such as Figure 1 - Figure 9 As shown, the device includes a main body 1, a smoke inlet pipe 2, and a smoke outlet pipe 4. The smoke inlet pipe 2 is installed at the bottom of the main body 1, and the smoke outlet pipe 4 is installed at the top of the main body 1. Multiple sets of smoke guide plates 3 are installed inside the main body 1 of the device, and the multiple sets of smoke guide plates 3 are staggered inside the main body 1 of the device. The multiple sets of smoke guide plates 3 are inclined. The flue gas inside the kiln enters the main body 1 of the device through the smoke inlet pipe 2. The flue gas flows through the multiple sets of smoke guide plates 3 and contacts the outer wall of the multiple sets of smoke guide plates 3. The dust inside the flue gas adheres to the outer wall of the multiple sets of smoke guide plates 3. The inclined arrangement of the multiple sets of smoke guide plates 3 reduces the flow opening between the multiple sets of smoke guide plates 3, increases the contact time between the flue gas and the multiple sets of smoke guide plates 3, and improves the adhesion efficiency of the multiple sets of smoke guide plates 3 to the dust inside the flue gas. One end of the flue gas inlet pipe 2 is connected to the flue gas outlet of the kiln. The flue gas inside the kiln enters the main body 1 of the device through the flue gas inlet pipe 2. One end of the flue gas outlet pipe 4 is connected to the flue gas inlet of the heat exchange device. The flue gas enters the heat exchange device through the flue gas outlet pipe 4.

[0029] Please see Figure 3 - Figure 6A drive motor 5 is installed at the bottom of the main body 1 of the device. A drive shaft 6 is installed at the output end of the drive motor 5, and one end of the drive shaft 6 extends into the interior of the main body 1 of the device. Two sets of first drive bevel gears 7 and second drive bevel gears 15 are installed on the outer wall of the drive shaft 6. When the drive motor 5 is started, it drives the drive shaft 6 to rotate alternately clockwise and counterclockwise. When the drive shaft 6 rotates, it drives the two sets of first drive bevel gears 7 and second drive bevel gears 15 to rotate.

[0030] Please see Figure 3 - Figure 6 The main body 1 of the device has two sets of first transmission shafts 8 movably installed inside. Each set of first transmission shafts 8 has a first transmission bevel gear 9 installed at one end. The two sets of first transmission bevel gears 9 are respectively engaged with two sets of first drive bevel gears 7. The two sets of first drive bevel gears 7 rotate and are respectively engaged with the two sets of first transmission bevel gears 9. Therefore, the two sets of first transmission bevel gears 9 rotate, thereby driving the two sets of first transmission shafts 8 to rotate.

[0031] Please see Figure 2 - Figure 7 The main body 1 of the device is symmetrically equipped with mounting frames 13 on its outer wall. The inner walls of the two sets of mounting frames 13 are movably equipped with movable cylinders 10, and the multiple sets of movable cylinders 10 are connected by toothed synchronous belts. The two sets of first drive shafts 8 are respectively connected to two sets of movable cylinders 10 by toothed synchronous belts. The two sets of first drive shafts 8 rotate, and the two sets of first drive shafts 8 are respectively connected to two sets of movable cylinders 10 by toothed synchronous belts. Therefore, the two sets of movable cylinders 10 rotate, and the multiple sets of movable cylinders 10 are connected by toothed synchronous belts, so the multiple sets of movable cylinders 10 rotate synchronously.

[0032] Please see Figure 4 - Figure 7 Each set of movable cylinders 10 has a telescopic column 11 movably installed on its inner wall, and the outer walls of the telescopic columns 11 are threadedly connected to the inner walls of the movable cylinders 10. Each set of telescopic columns 11 extends into the main body 1 of the device and has a push plate 12 installed at one end. The outer walls of the push plates 12 are movably connected to the outer walls of the smoke guide plates 3. The movable cylinders 10 rotate synchronously. The inner walls of the movable cylinders 10 are threadedly connected to the outer walls of the telescopic columns 11, and each set of telescopic columns 11 has a push plate 12 installed at one end. Therefore, the telescopic columns 11 drive the push plates 12 to move.

[0033] Please see Figure 7Each of the multiple push plates 12 has a "V" shaped end and the back of the multiple push plates 12 is inclined. When the multiple push plates 12 clean the outer wall of the multiple smoke guide plates 3, the "V" shaped end of the multiple push plates 12 prevents dust from moving to the back of the multiple push plates 12. When the multiple push plates 12 are reset, the dust moves to the front of the multiple push plates 12 through the inclined surface of the back of the multiple push plates 12.

[0034] Please see Figure 4 - Figure 8 A second drive shaft 16 is movably installed on the inner wall of the main body 1 of the device. A second drive bevel gear 17 is installed at one end of the second drive shaft 16, and the second drive bevel gear 17 is meshed with the second drive bevel gear 15. The second drive bevel gear 15 rotates, and the second drive bevel gear 15 is meshed with the second drive bevel gear 17. Therefore, the second drive bevel gear 17 rotates, thereby driving the second drive shaft 16 to rotate.

[0035] Please see Figure 3 - Figure 4 The device body 1 has a material drop chute 14 at the bottom, and the upper end of the material drop chute 14 is inclined. A collection box 24 is installed at the bottom of the material drop chute 14. Dust clumps fall to the upper end of the material drop chute 14 and then enter the collection box 24 through the material drop chute 14.

[0036] Please see Figure 4 - Figure 9 A first baffle 20 is movably installed on the upper end of the material discharge chute 14. Two sets of first limiting shafts 18 are mounted on the outer end of the main body 1 of the device, and the two sets of first limiting shafts 18 are connected by a toothed synchronous belt. One end of one set of first limiting shafts 18 is provided with a first one-way bearing 19, and one end of one set of first limiting shafts 18 is connected to the second transmission shaft 16 by a toothed synchronous belt. The outer walls of both sets of first limiting shafts 18 are provided with reciprocating threaded grooves, and the inner wall of the first baffle 20 is provided with protrusions that are movably connected to the reciprocating threaded grooves on the outer walls of the two sets of first limiting shafts 18. The second transmission shaft 16 is connected to one set of first limiting shafts 18 by a toothed synchronous belt. Therefore, one end of one set of first limiting shafts 18 rotates, and the two sets of first limiting shafts 18 are connected by a toothed synchronous belt and rotate synchronously. The reciprocating threaded grooves on the outer walls of the two sets of first limiting shafts 18 are movably connected to the protrusions on the inner wall of the first baffle 20, so the first baffle 20 moves back and forth.

[0037] Please see Figure 4 - Figure 9A first baffle 20 is movably installed on the upper end of the material discharge chute 14. Two sets of first limiting shafts 18 are mounted on the outer end of the main body 1 of the device, and the two sets of first limiting shafts 18 are connected by a toothed synchronous belt. One end of one set of first limiting shafts 18 is provided with a first one-way bearing 19, and one end of one set of first limiting shafts 18 is connected to the second transmission shaft 16 by a toothed synchronous belt. The outer walls of both sets of first limiting shafts 18 are provided with reciprocating threaded grooves, and the inner wall of the first baffle 20 is provided with protrusions that are movably connected to the reciprocating threaded grooves on the outer walls of the two sets of first limiting shafts 18. The second transmission shaft 16 is connected to one set of first limiting shafts 18 by a toothed synchronous belt. Therefore, one end of one set of first limiting shafts 18 rotates, and the two sets of first limiting shafts 18 are connected by a toothed synchronous belt and rotate synchronously. The reciprocating threaded grooves on the outer walls of the two sets of first limiting shafts 18 are movably connected to the protrusions on the inner wall of the first baffle 20, so the first baffle 20 moves back and forth.

[0038] The working principle of this invention is as follows: When the staff uses this device to recover and utilize the waste heat of flue gas, the flue gas inside the kiln enters the main body 1 of the device through the flue gas inlet pipe 2. The flue gas flows through multiple sets of smoke guide plates 3 and contacts the outer wall of the multiple sets of smoke guide plates 3. The dust inside the flue gas adheres to the outer wall of the multiple sets of smoke guide plates 3. The multiple sets of smoke guide plates 3 are inclined, which reduces the flow opening between the multiple sets of smoke guide plates 3, increases the contact time between the flue gas and the multiple sets of smoke guide plates 3, and improves the adhesion efficiency of the multiple sets of smoke guide plates 3 to the dust inside the flue gas. Then the flue gas enters the heat exchange device through the flue gas outlet pipe 4 to recover and utilize the waste heat of the flue gas. When the flue gas enters the main body 1 of the device, the drive motor 5 starts and drives the drive shaft 6 to rotate alternately clockwise and counterclockwise. When the drive shaft 6 rotates clockwise, it drives the two sets of first drive bevel gears 7 and the second drive bevel gears 15 to rotate clockwise. The two sets of first drive bevel gears 7 are respectively meshed with the two sets of first transmission bevel gears 9, so the two sets of first transmission bevel gears 9 rotate, thereby driving the two sets of first transmission shafts 8 to rotate. The two sets of first transmission shafts 8 are respectively connected to two sets of movable cylinders 10 through toothed synchronous belts, so the two sets of movable cylinders 10 rotate. When two sets of movable cylinders 10 rotate, the multiple sets of movable cylinders 10 are connected to each other by toothed synchronous belts, so the multiple sets of movable cylinders 10 rotate synchronously. The inner walls of the multiple sets of movable cylinders 10 are threadedly connected to the outer walls of the multiple sets of telescopic columns 11, and each set of telescopic columns 11 is equipped with a push plate 12 at one end. Therefore, the one end of the multiple sets of telescopic columns 11 moves towards the outer wall of the multiple sets of movable cylinders 10, thereby driving the multiple sets of push plates 12 to move. The multiple sets of push plates 12 clean the dust adhering to the outer wall of the multiple sets of smoke guide plates 3, so as to prevent the multiple sets of smoke guide plates 3 from losing their ability to adhere to dust in the flue gas after dust adheres to the outer wall, thus affecting the dust cleaning effect in the flue gas and improving the long-term use effect of the multiple sets of smoke guide plates 3. When the second drive bevel gear 15 rotates, it meshes with the second transmission bevel gear 17, causing the second transmission bevel gear 17 to rotate, which in turn drives the second transmission shaft 16 to rotate. The second transmission shaft 16 is connected to a set of first limiting shafts 18 and a set of second limiting shafts 21 via toothed synchronous belts. Therefore, one end of the set of first limiting shafts 18 and one end of the set of second limiting shafts 21 rotate. Due to the setting of the second one-way bearing 22, the other end of the set of second limiting shafts 21 does not rotate. When one end of a set of first limiting shafts 18 rotates, the other end of a set of first limiting shafts 18 rotates. The two sets of first limiting shafts 18 are connected by a toothed synchronous belt. The two sets of first limiting shafts 18 rotate synchronously. The reciprocating thread grooves on the outer walls of the two sets of first limiting shafts 18 are movably connected to the protrusions on the inner walls of the first baffle 20. Therefore, the first baffle 20 moves back and forth, so that the upper end of the discharge chute 14 is in a reciprocating opening and closing state. After the multiple sets of push plates 12 push the dust adhering to the outer walls of the multiple sets of smoke guide plates 3, the dust combines into a block during the pushing process and falls down through the inclined multiple sets of smoke guide plates 3, and finally falls to the upper area of ​​the discharge chute 14. At this time, the upper end of the discharge chute 14 is in a reciprocating opening and closing state, and the clump of dust falls to the upper end of the second baffle 23. When the multiple sets of push plates 12 move to one end of the multiple sets of smoke guide plates 3 respectively, the first baffle 20 moves to the upper end of the discharge chute 14. When the discharge chute 14 is in the closed state, the drive motor 5 drives the drive shaft 6 to rotate counterclockwise, so that the multiple sets of push plates 12 reset displacement. Since the back ends of the multiple sets of push plates 12 are all inclined, the outer wall of the multiple sets of smoke guide plates 3 is cleaned again during the reset process of the multiple sets of push plates 12. Some dust clumps slide down through the inclined surface of the back end of the multiple sets of push plates 12 to the front end area of ​​the multiple sets of push plates 12, and finally the dust clumps fall to the upper end of the first baffle 20. When the drive shaft 6 rotates counterclockwise, it drives the second transmission shaft 16 to rotate, thereby driving one end of a set of first limiting shafts 18 and one end of a set of second limiting shafts 21 to rotate. Due to the setting of the first one-way bearing 19, the other end of the set of first limiting shafts 18 does not rotate, while the other end of the set of second limiting shafts 21 rotates. The two sets of second limiting shafts 21 are connected by a toothed synchronous belt, so the two sets of second limiting shafts 21 rotate synchronously. The reciprocating thread grooves on the outer wall of the two sets of second limiting shafts 21 are movably connected to the protrusions on the inner wall of the second baffle 23. The second baffle 23 moves back and forth, so that the lower end of the discharge chute 14 is in a reciprocating opening and closing state. The dust clumps on the upper end of the second baffle 23 fall into the collection box 24, and the collection box 24 collects the dust clumps.
