Abstract
Disclosed is a rotary drum filter screen which is the structural improvement on the water filtration device used for nuclear power plant, in particular to the improvement on the structure of the rotary filter screen. The utility model solves the problems of poor rigidity, heavy main shaft wheel hub and high manufacturing cost found in the rotary filter screen in the prior art. The rotary drum filter screen comprises a main shaft, wheel hubs, main spokes and circular support pieces; the wheel hubs are mounted on the main shaft; the main spokes are respectively mounted on the wheel hubs which are symmetrically mounted; the main spokes are symmetrical and evenly mounted on each wheel hub; the main spokes construct the A-shaped structure to improve the structural strength and the structural rigidity; thereby, the stability is improved; the volumes of main shaft and wheel hubs are reduced while the strength, rigidity and stability are improved; the structural weight is reduced so that the manufacturing cost is reduced.
Description
Technical field:
The invention is the improvement to the equipment for filtering water structure that is used for nuclear power plant, especially to the improvement of rotary sieve structure.
Background technology:
At present, the rotary sieve that uses in thermal power plant, nuclear power plant is to make a king spoke annular groove is installed on the main shaft wheel hub, and king spoke is installed in and forms the I word shape in the annular groove, the king spoke place in one plane, this poor structure rigidity, the main shaft wheel hub structure is big, weight is big, the manufacturing cost height.
Summary of the invention:
The purpose of the invention provides and a kind ofly can improve structural strength, structural rigidity, increases stability, reduces construction weight, reduces manufacturing cost; The purpose of the invention is to realize by following technical scheme; Cydariform rotary sieve: comprise main shaft, wheel hub, king spoke, circle support member, king spoke is installed on the wheel hub, wheel hub is installed on the main shaft, it is characterized in that king spoke is installed in respectively on the wheel hub of two symmetry installations, becoming on each wheel hub distributes symmetrically and evenly installs king spoke, king spoke constitutes " A " font structure, king spoke is connected with justifying support member in the outer rim of king spoke.
The advantage of the invention: owing to king spoke being mounted to " A " font structure, increased structural strength, improved structural rigidity, thereby improved stability, thereby on intensity, rigidity, stability-enhanced basis, reduced the volume of main shaft, wheel hub, reduce the weight of structure, therefore reduced manufacturing cost.
Description of drawings:
Fig. 1 is the structural representation of cydariform rotary sieve;
Fig. 2 is the side view of Fig. 1.
Among the figure: 1. king spoke 2. wheel hubs 3. main shafts 4. are justified support members
The specific embodiment:
The cydariform rotary sieve, comprise main shaft, wheel hub, king spoke, circle support member, wheel hub is installed on the main shaft, king spoke is installed in respectively on the wheel hub of two symmetry installations, becoming on each wheel hub distributes symmetrically and evenly installs king spoke, king spoke constitutes " A " font structure, king spoke is connected the support member of installation warp-wise between king spoke with the circle support member in the outer rim of king spoke.
The technical program is that king spoke is mounted to " A " the font structure, triangularity, utilize leg-of-mutton stability, reach the purpose that improves its rigidity, the main shaft stress point is distributed near the both sides, center 2 points by the center, thereby improves the stress of the stressed and wheel hub of main shaft, reduced the size of main shaft and wheel hub, alleviate weight, reached the raising rigidity, reduced the purpose of manufacturing cost.
