Using resin material, the rotation direction of damping bearing 11 is set as in the rotation direction for corresponding to the insertion mounting groove 8 of installing frame 6
It is locked, it is freely rotated in the other directions.
Specific work process: directly that the filler 7 for needing to take out is right when needing to take out filler 7 and being replaced or safeguarded
The installing frame 6 answered proposes that during proposing installing frame 6, friction washer 12 offsets with vertical channel steel 9 from mounting groove 8, this
When damping bearing 11 be freely rotated, vertical channel steel 9 be installing frame 6 upward force of rolling friction is provided, force of rolling friction is smaller, peace
Framing up 6 smooth can propose.
During installing frame 6 is inserted into mounting groove 8, friction washer 12 offsets with installing frame 6, and damping bearing 11 is locked at this time
Extremely, vertical channel steel 9 is that installing frame 6 provides upward force of sliding friction, reduces the speed that installing frame 6 is inserted into, and with installation
The depth that frame 6 is inserted into mounting groove 8 increases, and the resistance provided is bigger, effectively protects to mounting groove 8.
Embodiment 3: small region sewage treatment system, as shown in fig. 6, including the contact-oxidation pool such as embodiment 1 or embodiment 2
2, it further include adjusting acidification pool 1, sedimentation basin 3 and clear water reserviors 4, wherein adjusting acidification pool 1, contact-oxidation pool 2, sedimentation basin 3 and clear
Pond 4 is sequentially connected, and contact-oxidation pool 2 is provided with submersible aerator, installing submersible pump (not shown) in clear water reserviors 4.
The utility model has the advantages that community wastewater is collected, is introduced into adjusting acidification pool 1, the organic matter in water is degraded, in anaerobism item
Phosphorus contained in sewage and bacterial cell is released under part with resolvability phosphorus, and is absorbed by bacterium；It adjusts in acidification pool 1
Sewage flow automatically to contact-oxidation pool 2 again, contact-oxidation pool 2 is provided with submersible aerator, waste water and the stirring strong in air
Effect is lower and sludge is sufficiently mixed, the organic matter in waste water because in sludge the metabolism of microorganism due to be absorbed removal
Fall, since aerobic aeration can be removed the amine nitrogen in waste water by nitrification；The water can be extracted out from the processing of sedimentation basin 3, sludge is flow to
Qualified environmental sanitation department is separately asked to handle；Supernatant liquor then flows into clear water reserviors 4 after being sterilized with bleaching powder, in clear water reserviors 4
Purified water is carried out reuse by installing submersible pump.
And when needing to take out filler 7 and being replaced or safeguarded, the corresponding installing frame of filler 7 that directly will need to take out
6 propose from mounting groove 8, simple to operate.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
