Description

Technical Field

[0001] The utility model relates to the technical field of full hydrogen bell-type furnaces, in particular to an energy-saving circulating fan for full hydrogen bell-type furnaces. Background Art

[0002] The full hydrogen bell-type furnace is a common metal heat treatment equipment, mainly used for annealing. During the operation of the full hydrogen bell-type furnace, cooling starts from the heating bell still on the furnace table. First, air must be blown into the heating bell, and then the heating bell is removed, and then the cooling bell is hoisted. The fan on the cooling bell draws air from the surrounding environment to cool the inner bell. The energy-saving circulating fan for the full hydrogen bell-type furnace is a fan specially designed for the full hydrogen bell-type furnace. Its main function is to provide a strong airflow to help the materials in the furnace to cool quickly and effectively.

[0003] The impeller and shaft of the existing full hydrogen bell-type furnace energy-saving circulating fan are operated in a high temperature environment of 800°C for a long time. Since the impeller and shaft are mostly made of metal, the surface temperature of the impeller and shaft is high, which can easily transfer the high temperature to the inside of the fan, making the internal temperature of the fan too high, which can easily affect the service life of the fan and may easily cause internal damage to the fan. To this end, we provide an energy-saving circulating fan for full hydrogen bell-type furnace to solve the above problems. Utility Model Content

[0025] It includes a fan body 1, a first combination shell 5 and a second combination shell 12. The first combination shell 5 and the second combination shell 12 are both semi-cylindrical closed shells, and the first combination shell 5 and the second combination shell 12 are threadedly detachably connected. The bottom end of the first combination shell 5 is symmetrically penetrated with multiple groups of through holes 10, and the bottom end of the through holes 10 is provided with a nozzle 11. The top of the second combination shell 12 is symmetrically penetrated with three groups of through grooves 14, and the through grooves 14 are located below the nozzle 11.

[0026] The combination shell No. 1 5 and the combination shell No. 2 12 are both semi-circular cylindrical shells, and the combination shell No. 1 5 and the combination shell No. 2 12 are both provided with two layers. A certain amount of cooling water can be stored inside the combination shell No. 1 5 and the combination shell No. 2 12. After the combination shell No. 1 5 and the combination shell No. 2 12 are threadedly assembled, the combination shell No. 1 5 and the combination shell No. 2 12 can be wrapped around the outside of the fan body 1 in a cylindrical shape to cool and protect the fan body 1. The external water supply equipment is connected with the water inlet pipe 6, so that the external cooling water can be transported into the interior of the combination shell No. 1 5. The cooling water inside the combination shell No. 1 5 can enter the interior of the nozzle 11 through the through hole 10 to spray the running shaft 2, thereby effectively reducing the temperature of the shaft 2. The excess cooling water sprayed by the nozzle 11 can flow through the through groove 14 to the interior of the combination shell No. 2 12 for storage.

[0027] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: an energy-saving circulating fan for a full hydrogen bell-type furnace;

[0028] A rotating shaft 2 is disposed at the output end of the fan body 1, an impeller 3 is disposed at the other end of the rotating shaft 2, a first blocking ring 4 is disposed on the outer side of the rotating shaft 2, and two groups of the first blocking ring 4 are symmetrically arranged.

[0029] The fan body 1 is an energy-saving circulating fan for a full hydrogen hood-type furnace. When the fan body 1 is running, the rotating shaft 2 arranged at the output end of the fan body 1 can drive the impeller 3 to rotate inside the full hydrogen hood-type furnace. The airflow generated by the rotation of the impeller 3 can help the material in the full hydrogen hood-type furnace to be quickly and effectively cooled. The No. 1 blocking ring 4 is symmetrically arranged on the outside of the rotating shaft 2. After the two symmetrically arranged groups of No. 1 blocking rings 4 are respectively staggered with the combined No. 1 combination ring 8, No. 2 combination ring 9, No. 3 combination ring 15 and No. 4 combination ring 16, the No. 1 blocking ring 4 can effectively prevent the cooling water sprayed from the nozzle 11 from leaking into the interior of the No. 2 combination shell 12.
