Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a high temperature resistant double-layer impeller fan. Background Art

[0002] The impeller refers to the wheel disk with moving blades, which is a component of the impulse steam turbine rotor, and can also refer to the general term for the wheel disk and the rotating blades installed on it. A fan equipped with an impeller can increase the wind force of the fan.

[0003] After searching, a Chinese patent discloses a high-temperature resistant double-layer impeller fan (authorization announcement number CN204025100U), including a motor, a fan body and an impeller, the bottom surface of the motor is fixedly connected to the top surface of the fan body, and a main shaft is arranged at the bottom end of the motor, and the main shaft passes through the center position of the bottom surface of the fan body and is movably connected to the bottom surface of the fan body; the bottom end of the main shaft is fixedly connected to the impeller; a plug is arranged on the inner wall of the top surface of the fan body, and a water cooling jacket surrounding the main shaft is arranged on the top surface of the fan body, and a water outlet is arranged on the water cooling jacket, and a water inlet is arranged on the top surface of the fan body, and the water inlet is connected to the bottom surface of the water cooling jacket through a pipeline.

[0029] Reference Figure 1-4A high temperature resistant double-layer impeller fan comprises a shell 1, both sides of the inner wall of the shell 1 are provided with mounting grooves 2, a threaded rod 3 is rotatably connected inside one of the mounting grooves 2, a fixing rod 4 is fixedly connected inside the other mounting groove 2, a threaded block 6 is threadedly connected to the outer side of the threaded rod 3, a slider 10 is slidably connected to the outer side of the fixing rod 4, the threaded block 6 and the slider 10 are both slidably connected to the inner wall of the mounting groove 2, a driving motor 5 is arranged inside the shell 1, a rotating shaft 20 is arranged inside the shell 1 and on one side of the driving motor 5, two impeller bodies 9 are fixedly connected to the outer side of the rotating shaft 20, a clamping mechanism is arranged on the side of the slider 10 close to the threaded block 6, a detachable mechanism is arranged between the impeller body 9 and the driving motor 5, and a stabilizing mechanism is arranged on the inner wall of the shell 1.

[0030] When in use, the threaded block 6 can be driven to move in the installation groove 2 by rotating the threaded rod 3, and the driving motor 5 can be made more stable during movement by cooperating with the fixing rod 4 and the slider 10, so that the impeller body 9 can be pushed out from the deeper casing 1, thereby facilitating the staff to clean the impeller body 9 with dust attached to the surface and reduce the adhesion of dust, thereby improving the heat dissipation effect and service life of the impeller body 9.

[0031] Reference Figure 3 The clamping mechanism includes a connecting piece 11 fixedly connected to the side of the slider 10 close to the threaded block 6, and clamping blocks 12 are fixedly connected to both sides of the driving motor 5. A clamping groove used in conjunction with the clamping block 12 is opened inside the connecting piece 11, and the clamping groove is clamped with the clamping block 12. A through rod 13 is fixedly connected to one side of the clamping block 12 close to the connecting piece 11, and an external thread is provided on the outer side of the through rod 13. An anti-slip sheet 14 is provided on the outer side of the through rod 13, and a nut 15 is threadedly connected to the outer side of the through rod 13. The connecting piece 11, the anti-slip sheet 14 and the nut 15 are in conflict with each other.

[0032] When the damaged drive motor 5 needs to be removed from the housing 1, the detachable mechanism can be used to first release the fixing of the rotating shaft 20 and the drive motor 5, and loosen the nut 15 on the anti-drop sheet 14, and then move the drive motor 5 to the right, so that the clamping block 12 on the drive motor 5 can be separated from the clamping groove in the connecting piece 11, thereby facilitating the replacement operation of the damaged drive motor 5 with the connecting piece 11, avoiding the higher investment cost brought by the overall replacement, and the above-mentioned installation and disassembly methods are relatively convenient.

[0033] Reference Figure 4The stabilizing mechanism includes fixed blocks 18 fixedly connected to both sides of the inner wall of the shell 1, and the ends of the fixed blocks 18 away from the driving motor 5 are fixedly connected to the limiting rod 7. A stabilizing member 19 is provided on the side of the rotating shaft 20 away from the driving motor 5, and the end of the rotating shaft 20 away from the driving motor 5 is rotatably installed on the outside of the stabilizing member 19, and the stabilizing member 19 is slidably connected to the limiting rod 7.

[0034] During use, when it is necessary to clean the dust on the surface of the impeller body 9, the impeller body 9 needs to be pushed out of the shell 1 so that the stabilizing member 19 slides on the limiting rod 7. This not only improves the stability of the impeller body 9 during operation, but also activates the positioning function, so that during the installation process, the impeller body 9 can slide directly into the shell 1 according to the limiting rod 7, thereby improving the installation efficiency.

[0035] Reference Figure 4 The detachable mechanism includes two mounting plates 16 arranged between the output shaft of the driving motor 5 and the rotating shaft 20. The output shaft of the driving motor 5 and the rotating shaft 20 are fixedly connected to the corresponding mounting plates 16 respectively. Bolts 17 are equidistantly arranged between the two mounting plates 16. The two mounting plates 16 are connected by multiple bolts 17.

[0036] When in use, the bolts 17 and the mounting plate 16 are arranged to facilitate disassembly and installation of the rotating shaft 20 and the driving motor 5 .

[0037] Reference Figure 2 The end of the limit rod 7 away from the stabilizing member 19 is provided with an external thread, and the outer thread of the limit rod 7 is connected to a threaded seat 8. The setting of the threaded seat 8 can prevent the rotating shaft 20 from falling off after the fixing with the driving motor 5 is released.

[0038] Reference Figure 2 One end of the threaded rod 3 extends to the outside of the shell 1 and is fixedly connected with an adjusting knob. The surfaces of the shell 1, the impeller body 9 and the drive motor 5 are coated with high-temperature resistant materials. The adjusting knob is set to facilitate the threaded rod 3 to rotate.

[0039] Reference Figure 1 A maintenance door is sealed and hinged on the outer side of the shell 1. The maintenance door is a visual glass. Through the visual glass, the staff can easily observe the situation inside the shell 1.

[0040] Working principle: First, turn the adjusting knob, and the threaded block 6 can be driven to move in the installation groove 2 through the rotation of the threaded rod 3, and the driving motor 5 can be made more stable during the movement through the cooperation of the fixing rod 4 and the slider 10, so that the impeller body 9 can be pushed out from the deep housing 1, so that the staff can clean the impeller body 9 with dust on the surface and reduce the adhesion of dust, so as to improve the heat dissipation effect and service life of the impeller body 9;

[0041] When it is necessary to clean the dust on the surface of the impeller body 9, it is necessary to push the impeller body 9 out of the casing 1 so that the stabilizing member 19 slides on the limiting rod 7. The setting of the stabilizing mechanism can not only improve the stability of the impeller body 9 during operation, but also start the positioning function, so that the impeller body 9 can directly slide into the casing 1 according to the limiting rod 7 during the installation process, thereby improving the installation efficiency. When it is necessary to remove the damaged drive motor 5 from the casing 1, the detachable mechanism can be used to first release the fixing of the rotating shaft 20 and the drive motor 5, and loosen the nut 15 on the anti-slip sheet 14, and then move the drive motor 5 to the right, so that the clamping block 12 on the drive motor 5 can be separated from the clamping groove in the connecting member 11, thereby facilitating the replacement operation of the damaged drive motor 5 with the connecting member 11, avoiding the high investment cost brought about by the overall replacement, and the above-mentioned installation and disassembly methods are relatively convenient.
