[0016] The present invention provides a liquid heat transfer type heat preservation fan, which has the following beneficial effects:

[0017] 1. Since the outer shell and the inner shell of the present invention form a hollow structure, when the liquid with a certain temperature requirement outside is filled between the outer shell and the inner shell through the liquid pipette, a larger area can be used for heat transfer and heat preservation, so as to prevent the viscous medium from condensing in the casing and impurities from agglomerating and adhering to the impeller, thereby destroying the dynamic balance of the rotor and avoiding potential safety hazards to the safe operation of the unit. In addition, during operation, when the main shaft drives the impeller to rotate, the fan blades are also driven to rotate through the driving gear, the driven gear, the transmission cylinder and the transmission rod, so that negative pressure is formed at the bottom of the liquid pipette to adsorb liquid of a certain temperature. There is no need to add an additional driving source, and the position of the adjusting sleeve can be moved by only loosening the fastener, so that the driving gear is separated from the driven gear, thereby reducing the load on the main shaft when heat preservation is not required.

[0018] 2. The present invention utilizes the guide plate to pre-guide the airflow entering the fan, so that the airflow has a certain degree of deflection, reduces the airflow impact loss, and improves the efficiency of the fan. At the same time, the liquid overflowing from the outer shell will flow into the diversion sleeve through the liquid outlet pipe, and flow to the flow channel inside the guide plate through the first through hole on the rotating tube, so as to exchange heat with the guide plate and avoid condensation on the surface of the guide plate due to the low temperature. The liquid inside the guide plate will enter the fixed sleeve through the second through hole on the guide sleeve, and then be discharged through the return pipe. The liquid inside the fixed sleeve can exchange heat with the air inlet pipe, thereby increasing the overall heat exchange area and further enhancing the thermal insulation performance of the fan.

[0019] 3. When the electric cylinder is started, the synchronous ring will be driven to rotate outside the fixed sleeve. At this time, the slide rod will push and pull the top plate through the rotating plate and the rotating seat to rotate the rotating tube, thereby driving all the guide plates to rotate at the same time, so as to adjust the deflection angle of the guide plate according to the needs, guide the airflow to enter the impeller at a suitable angle, optimize the air intake angle, reduce the impeller load, and extend the service life of the equipment. At the same time, after the rotating tube rotates, it can still communicate with the diverter sleeve and the inside of the guide plate through the first through hole, and the guide sleeve can communicate with the inside of the fixed sleeve through the second through hole, so that the heat exchange effect is not affected after the angle is adjusted.

[0020] 4. The inner wall of the sealing sleeve of the present invention is in the shape of an inlaid maze, and cooperates with the sealing ring and the graphite ring to form a multiple sealing structure, which is beneficial to improving the overall sealing performance of the fan, ensuring that the sealing body structure is spark-proof, corrosion-resistant, zero-leakage, and anti-clogging. At the same time, the nitrogen chamber can be filled with nitrogen of a certain pressure through the one-way valve. At this time, the air pressure is detected by the air pressure sensor, and when the seal leaks due to aging or wear, the air pressure sensor will detect that the pressure is lower than the preset threshold, and the controller can start the buzzer to warn the staff so that the fan can be maintained and repaired in time. The impeller and the main shaft of the equipment adopt a tapered shaft, and a locking nut clamping structure is used to facilitate the rapid disassembly and assembly of the main shaft and the impeller, and there is no need to use the traditional red set assembly process, saving resources and avoiding safety hazards under installation conditions where open flames cannot be used.

The composite sealing assembly 5 includes a sealing sleeve 501, a sealing ring 502, a graphite ring 503 and a nitrogen chamber 504. A sealing sleeve 501 is arranged in the middle of one side of the inner shell 808, and a sealing ring 502 is arranged inside the sealing sleeve 501, a graphite ring 503 is arranged inside the sealing sleeve 501, and a nitrogen chamber 504 is arranged inside the sealing sleeve 501.

[0031] The specific operation is as follows: nitrogen is filled into the nitrogen chamber 504 inside the sealing sleeve 501 through the one-way valve 505 with a certain pressure of nitrogen. Then, when the motor 1 drives the main shaft 4 to rotate through the coupling 2 and the transmission box group 3, the inner wall of the sealing sleeve 501 is in the shape of an inlaid maze, and cooperates with the sealing ring 502 and the graphite ring 503 to form a multiple sealing structure, which is beneficial to improve the overall sealing performance of the fan.

When the main shaft 4 drives the impeller 7 to rotate, it will also drive the fan blade 805 to rotate through the driving gear 801, the driven gear 802, the transmission cylinder 803 and the transmission rod 804, so that negative pressure is formed at the bottom of the suction tube 806 to adsorb the liquid at a certain temperature. When the liquid with a certain temperature requirement fills the space between the outer shell 807 and the inner shell 808, there will be a larger area for heat transfer and heat preservation, so as to prevent the viscous medium from condensing in the casing and impurities from agglomerating and adhering to the impeller 7, thereby destroying the dynamic balance of the rotor and avoiding safety hazards to the safe operation of the unit. In addition, the position of the adjusting sleeve 810 can be moved by loosening the fastener 811, so that the driving gear 801 is separated from the driven gear 802, thereby reducing the load on the main shaft 4 when heat preservation is not required.

The flow tube 909, an adjustment component 10 is arranged on the outer side of one end of the fixed sleeve 902, and the adjustment component 10 includes an electric cylinder 1001, a synchronous ring 1002 and a slide bar 1003. The outer side of the fixed sleeve 902 is rotatably connected to the electric cylinder 1001, and one end of the electric cylinder 1001 is rotatably connected to the synchronous ring 1002, the synchronous ring 1002 is rotatably connected to the fixed sleeve 902, and a slide bar 1003 is fixed to one side of the synchronous ring 1002. The adjustment component 10 also includes a rotating plate 1004, a rotating seat 1005 and a top plate 1006. The outer side of the slide bar 1003 is sleeved with the rotating plate 1004, and the end of the rotating plate 1004 is rotatably connected to the rotating seat 1005, and the bottom of the rotating seat 1005 is rotatably connected to the top plate 1006, and the top plate 1006 is fixedly connected to the rotating tube 904;

[0033] The specific operation is as follows: first, start the electric cylinder 1001 to drive the synchronous ring 1002 to rotate outside the fixed sleeve 902. At this time, the slide bar 1003 will push and pull the top plate 1006 through the rotating plate 1004 and the rotating seat 1005, so that the rotating tube 904 can rotate, thereby driving all the guide plates 908 to rotate at the same time, so as to adjust the deflection angle of the guide plates 908 according to needs. Therefore, when the main shaft 4 drives the impeller 7 to rotate through the cone shaft 6 and sucks the airflow into the air inlet pipe 901, the airflow is guided to enter the impeller 7 at a suitable angle, optimize the air intake angle, reduce the load of the impeller 7, extend the service life of the equipment, and improve the fan. The efficiency is improved. At the same time, the liquid overflowing from the shell 807 will flow into the diverter sleeve 903 through the liquid outlet pipe 809, and flow to the flow channel inside the guide plate 908 through the first through hole 905 on the rotating tube 904, so as to exchange heat with the guide plate 908, thereby avoiding condensation on the surface of the guide plate 908 due to the low temperature. The liquid inside the guide plate 908 will enter the fixed sleeve 902 through the second through hole 907 on the guide sleeve 906, and then be discharged through the return pipe 909. The liquid inside the fixed sleeve 902 can exchange heat with the air inlet pipe 901, thereby increasing the overall heat exchange area and further enhancing the thermal insulation performance of the fan.

[0034] In summary, when the liquid heat transfer type heat preservation blower is used, firstly, the nitrogen chamber 504 inside the sealing sleeve 501 is filled with nitrogen of a certain pressure through the one-way valve 505, and then, the motor 1 drives the main shaft 4 to rotate through the coupling 2 and the transmission box group 3. At this time, the inner wall of the sealing sleeve 501 is in the shape of an inlaid maze, and cooperates with the sealing ring 502 and the graphite ring 503 to form a multiple sealing structure, which is beneficial to improve the overall sealing performance of the blower. At this time, the air pressure is detected by the air pressure sensor 506, and when the seal leaks due to aging or wear, the air pressure sensor 506 will detect that the pressure is lower than the preset threshold value, and the buzzer 508 can be activated through the controller 507 to warn the staff in time To maintain and repair the fan, then, when the main shaft 4 drives the impeller 7 to rotate, it will also drive the fan blade 805 to rotate through the driving gear 801, the driven gear 802, the transmission cylinder 803 and the transmission rod 804, so that negative pressure is formed at the bottom of the suction tube 806 to adsorb the liquid at a certain temperature. When the liquid with a certain temperature requirement fills the space between the outer shell 807 and the inner shell 808, there will be a larger area for heat transfer and heat preservation, so as to prevent the viscous medium from condensing in the casing and impurities from agglomerating and adhering to the impeller 7, thereby avoiding safety hazards to the safe operation of the unit, and only need to loosen the fastener 811 to move the position of the adjusting sleeve 810, so that the driving gear 801 is separated from the driven gear 802, thereby When heat preservation is not required, the load on the main shaft 4 is reduced. Then, when the main shaft 4 drives the impeller 7 to rotate through the conical shaft 6, the air flow will be sucked into the air inlet pipe 901. At this time, the guide plate 908 can be used to pre-guide the air flow entering the fan, so that the air flow has a certain degree of deflection, reducing the impact loss of the air flow. At the same time, the liquid overflowing from the shell 807 will flow into the diversion sleeve 903 through the liquid outlet pipe 809, and flow to the flow channel inside the guide plate 908 through the first through hole 905 on the rotating tube 904, so that the guide plate 908 can be heat exchanged to avoid condensation on the surface of the guide plate 908 due to the low temperature, and the liquid inside the guide plate 908 will enter through the second through hole 907 on the guide sleeve 906. The liquid in the fixed sleeve 902 can exchange heat with the air inlet pipe 901, thereby increasing the overall heat exchange area and further enhancing the thermal insulation performance of the fan. Finally, the electric cylinder 1001 can be started to drive the synchronous ring 1002 to rotate outside the fixed sleeve 902. At this time, the slide bar 1003 can push and pull the top plate 1006 through the rotating plate 1004 and the rotating seat 1005, so that the rotating tube 904 can rotate, thereby driving all the guide plates 908 to rotate at the same time, so as to adjust the deflection angle of the guide plate 908 according to the needs, guide the airflow to enter the impeller 7 at a suitable angle, optimize the air intake angle, reduce the load of the impeller 7, and extend the service life of the equipment.
