Abstract

The invention relates to a hub and spoke connecting structure of a drum-shaped filter screen and the drum-shaped filter screen. The hub and spoke connecting structure of the drum-shaped filter screen comprises a hub, a plurality of spokes, a plurality of connecting bolts, a plurality of supporting blocks and a plurality of adjusting screw rods. According to the connecting structure of the hub and the spokes of the drum-shaped filter screen, the force (namely the shearing force borne by the connecting bolts) borne by the connecting bolts in the length direction X of the spokes is reduced, and the risk that the connecting bolts are sheared off and the potential safety hazard are reduced. Besides, when the spokes are installed on the hub, the installation gaps between the spokes and the hub can be adjusted through the adjusting screws, and the spokes and the hub are fixed through the connecting bolts after the installation gaps between the spokes and the hub are adjusted, so that the meshing precision of the gear ring of the drum-shaped filter screen and the gear of the driving device is guaranteed, and the precision requirement of the drum-shaped filter screen is met.

Description

Technical field [0001] The present invention relates to the technical field of circulating water filtration systems, in particular to the hub and spokes of the drum screen, a drum filter. Background technique [0002] The drum filter is used as a nuclear power plant cold source "depth defense" system to resist the last level of large-scale filtration equipment of the sea organism. Its performance directly determines the safety and stability of the power plant cold source safety and unit safety, once the drum filter is faulty, It may cause the unit drop-up power or even the reactor stop. [0003] The drum filter is generally divided into two forms of "foreign inside out" and "inner progress", the difference between the "Intronization" type drum filter runs, drum filter Water outside water. Conversely, when the "external direction" type drum filter is run, the drum screen is in the inner water, so that the garbage such as sea organism can be intercepted on the outside of the drum f...
