Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-9 A cooling device for a natural circulation gasifier comprises a cooling box 1, an air outlet pipe 3 is fixedly mounted on the top of the cooling box 1, a controller 6 and a conveying pipe 5 are fixedly mounted on the outer wall of one end of the cooling box 1, an air inlet pipe 4 is fixedly mounted on the outer wall of the other end of the cooling box 1, a circular groove 9 is provided on the top of the cooling box 1, a movable groove 13 is provided on the inner wall of the air inlet pipe 4, a movable block 10 is movably connected to the inner wall of the cooling box 1, a heat pipe 7 is fixedly mounted on the inner wall of the cooling box 1, a temperature sensor 14 is fixedly mounted on the inner wall of the heat pipe 7 near one end of the conveying pipe 5, a solenoid valve 15 is fixedly mounted on the inner wall of the cooling box 1, a limit assembly 8 is provided on the inner wall of the air inlet pipe 4, an energy-saving assembly 12 is provided on the inner wall of the air outlet pipe 3, a limit groove 11 is provided on the inner wall of the air outlet pipe 3, and a gasifier body 2 is provided on the outer wall of the cooling box 1.

[0028] It should be noted that the hot air is transported to the inner wall of the heat pipe 7 by the inner wall of the air inlet pipe 4, and then the heat pipe 7 is cooled by the cold air in the cooling box 1. The air inside the heat pipe 7 is monitored by the temperature sensor 14. When the air inside the heat pipe 7 drops to a specific temperature, the temperature sensor 14 sends a signal to the solenoid valve 15 to open the valve, thereby transporting the cold air to the inner wall of the delivery pipe 5, and then transmitting it to the inner wall of the gasifier body 2 for cooling. After the air is exhausted, the limit assembly 8 returns to its unheated initial state to ensure that the interior of the heat pipe 7 is in a closed state to prevent hot air from mixing into the inner wall of the heat pipe 7 during the cold air delivery process, thereby ensuring effective cooling of the equipment.

[0029] In a preferred embodiment, the limit assembly 8 includes a limit block 801, the bottom of which is fixedly equipped with a movable column 802 and a spring 803, the end of the spring 803 away from the limit block 801 is fixedly equipped with a fixed block 804, and the outer wall of the movable column 802 is provided with an open groove 805.

[0030] It should be noted that when the heat of the inner wall of the air intake pipe 4 reaches a certain level, the limit block 801 moves on the inner wall of the limit groove 11 by virtue of the principle of thermal expansion and contraction, and at the same time drives the spring 803 to expand and contract. The limit block 801 drives the movable column 802 and the movable block 10 to move, so that the fixed block 804 is exposed to the inner wall of the heat pipe 7, thereby realizing the transfer of hot air from the inner wall of the air intake pipe 4 to the inner wall of the heat pipe 7.

[0031] In a preferred embodiment, the energy-saving component 12 includes a round block 1201, the top of the round block 1201 is fixedly equipped with a lifting block 1202, the top of the lifting block 1202 is respectively fixedly equipped with a spring 1203 and a fixed plate 1204, the inner wall of the fixed plate 1204 is rotatably connected to a fan 1205, and the outer wall of the fixed plate 1204 is rotatably connected to a rotor 1206.

[0032] It should be noted that after the hot air generated inside the cooling box 1 reaches a specific temperature, pressure is applied to the round block 1201 according to the principle of thermal expansion and contraction. As the round block 1201 moves, it drives the lifting block 1202 to expand and contract the spring 2 1203, so that the hot air inside the cooling box 1 flows from the inner wall of the lifting block 1202 to the inner wall of the outlet pipe 3. The hot air drives the fan 1205 to rotate on the inner wall of the fixed plate 1204, and then drives the rotor 1206 to rotate to generate electricity, thereby realizing energy saving of the equipment. After the hot air is discharged, the elastic potential energy of the spring 2 1203 is used to drive the spring 2 1203 to return to its initial state.

[0033] In a preferred embodiment, the fixed block 804 is fixedly assembled with the inner wall of the cooling box 1, the movable column 802 is fixedly assembled with the movable block 10, the spring 2 1203 is fixedly assembled with the inner wall of the limiting groove 11, the spring 1 803 is fixedly assembled with the inner wall of the movable groove 13, and the fan 1205 is fixedly assembled with the rotor 1206.

[0034] It should be noted that by firmly connecting the fixed block 804 to the inner wall of the cooling box 1, it is ensured that when the spring 1 803 applies pressure to the fixed block 804, the fixed block 804 is prevented from falling off. At the same time, the position of the spring 1 803 is limited by the movable groove 13.

[0035] In a preferred embodiment, the temperature sensor 14 and the solenoid valve 15 are both electrically connected to the controller 6 , and the temperature sensor 14 is electrically connected to the solenoid valve 15 , and the rotor 1206 is electrically connected to the temperature sensor 14 and the solenoid valve 15 .

[0036] It should be noted that the controller 6 transmits a signal, and the device starts running after receiving the signal. At the same time, the temperature sensor 14 directly sends a signal to the solenoid valve 15, so that the solenoid valve 15 starts working immediately after receiving the signal from the temperature sensor 14, and generates electricity by means of the rotation of the rotor 1206, and then transmits electricity to the temperature sensor 14 and the solenoid valve 15, thereby achieving the energy saving goal.

[0037] In a preferred embodiment, the air inlet pipe 4 and the delivery pipe 5 are both fixedly assembled with the outer wall of the gasifier body 2 , and the inner wall of the heat pipe 7 is larger than the outer wall of the air inlet pipe 4 .

[0038] It should be noted that the hot gas and cold air are transported and output to the inner wall of the gasifier body 2 with the help of the air inlet pipe 4 and the delivery pipe 5. Since the inner wall size of the heat pipe 7 is larger than the inner wall of the air inlet pipe 4, it is ensured that the moving block 10 and the moving column 802 will not cause damage to the inner wall of the heat pipe 7 when migrating to it.

[0039] Working principle: during the operation of the equipment, when the hot air generated inside reaches a certain temperature, according to the principle of thermal expansion and contraction, the hot air generates pressure on the component round block 1201, and through the movement of the round block 1201, the lifting block 1202 is driven to expand and contract the spring 2 1203, so that the hot air flows from the inner wall of the lifting block 1202 into the inner wall of the outlet pipe 3, and the hot air drives the fan 1205 to rotate on the inner wall of the fixed plate 1204, thereby driving the rotor 1206 to rotate to generate electricity, thereby realizing energy saving of the equipment. After the hot air is discharged, with the help of the elastic potential energy of the spring 2 1203, it drives the energy-saving component 12 to return to its initial state. When the hot air inside the gasifier body 2 is transported to the inner wall of the cooling box 1, the hot air reaches a certain temperature, and through thermal expansion and contraction, the limit block 801 moves on the inner wall of the limit groove 11, and at the same time drives the spring 1 803 is extended and retracted, and the movable column 802 and the movable block 10 are driven to move by the limit block 801, so that the fixed block 804 is exposed to the inner wall of the heat pipe 7, and the hot air is transported from the inner wall of the air inlet pipe 4 to the inner wall of the heat pipe 7, and the heat pipe 7 is cooled by the cold air inside the cooling box 1. The air inside the heat pipe 7 is detected by the temperature sensor 14. When the air inside the heat pipe 7 drops to a certain temperature, the temperature sensor 14 sends a signal to the solenoid valve 15 to open the valve. After the cold air is transported to the inner wall of the delivery pipe 5, it is continuously transported to the inner wall of the gasifier body 2 to cool the gasifier body 2. After the air is exhausted, the limit assembly 8 is restored to its initial unheated state to ensure that the inside of the heat pipe 7 is in a closed state to prevent hot air from entering the inner wall of the heat pipe 7 during the cold air delivery process, thereby improving the cooling effect of the equipment.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
