Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0014] Such as figure 1 As shown, the ultra-high temperature fan casing installation structure of the present invention includes a casing 2 installed on the main shaft 1 of the fan, a sealing assembly for sealing is arranged between the main shaft 1 and the casing 2, and the casing 2 is along the periphery of the casing 2 A connecting portion 6 is provided, and the connecting portion 6 is located on the plane on the casing 1 that is consistent with the horizontal plane of the fan shaft axis. The casing 2 is arranged on at least two supporting frames 4 through the connecting portion 6. Perform fixed support, and make a certain gap between the bottom of the casing 2 and the fan base 5;
[0015] In this example, if figure 1 and 2 , Two support frames 4 are arranged on the fan base 5, and the two support frames 4 are respectively located on the ...

The invention relates to the technical field of draught fans, in particular to an ultrahigh temperature draught fan shell installation structure with the working temperature being 650 DEG C and the highest resistant temperature being 800 DEG C. The ultrahigh temperature draught fan shell installation structure comprises a shell installed on a spindle of a draught fan; a sealing assembly used for sealing is arranged between the spindle and the shell; the shell is provided with connection parts along the periphery of the shell; the connection parts are located in the plane, consistent with the horizontal plane of the axis of the spindle of the draught fan, of the shell; the shell is arranged on at least two supporting frames through the connection parts; the connection parts are fixedly connected with the supporting frames; and the supporting frames are fixedly installed on a base of the draught fan. The installation mode of supporting the center of the shell is adopted, an upper shell body and a lower shell body of the shell extend towards the upper and lower sides of the center of the shell correspondingly, accordingly, sealing of the spindle of the draught fan cannot be influenced, and the sealing performance of the draught fan is ensured.
Description
technical field [0001] The invention relates to the field of fan technology, in particular to a fan casing installation structure with an operating temperature of 650°C and a maximum temperature resistance of 800°C. Background technique [0002] At present, in the field of high-temperature centrifugal fan technology, the working temperature of the fan is usually around 300°C. For example, the working temperature of the high-temperature fan in the denitrification system of a coal-fired power plant is between 300°C and 350°C. However, this high-temperature fan is difficult to apply to higher Operating temperature. In the domestic fan industry, the working temperature is 650°C, the pressure reaches 10kPa and above, and the air volume is 1500Nm 3 The demand for the application of ultra-high-temperature and high-pressure fans with small flow rate and high pressure is increasing; but at present, domestically, such ultra-high-temperature fans have not been applied to the urea pyro...
