Abstract
The utility model relates to a rotary manhole for a sewage treatment filter, and the rotary manhole is innovatively characterized by comprising a manhole fixed flange and a manhole cover, wherein the manhole cover is hinged with the manhole fixed flange, a plurality of locking grooves are uniformly distributed on the circumferential surface of the manhole cover, a plurality of moving bolts corresponding to the locking grooves are arranged on the circumferential surface of the manhole fixed flange, and the end part of a rod body of the moving bolt can rotate around a radial panel perpendicular to the manhole fixed flange; after the manhole cover covers the manhole fixed flange, the end part of the rod body of the moving bolt is rotatably embedded in the locking groove, and a locking nut is arranged on the rod body of the moving bolt through threaded connection; and the moving bolt is connected with the manhole fixed flange through a removable structure. The rotary manhole disclosed by the utility model has the advantages that when the manhole cover is required to be opened, through rotating the locking nut, the moving bolt rotates outwards so as to separate from the locking grooves, and the locking nut and the bolt are not required to be completely removed, thereby reducing the workload; and when the manhole cover is required to be locked, the locking is operated contrariwise, so that the rotary manhole is quick and convenient to install and disassemble.
Description
Technical field
The utility model relates to a kind of effluent treatment and filtering device manhole, particularly a kind of conveniently opening and closing rotary manhole of effluent treatment and filtering device efficiently.
Background technology
Sewage disposal is the water quality requirement of instigating sewage to reach a certain water body of draining or reuse, and to its process that purifies.Sewage disposal is widely used in building, agricultural, and the every field such as traffic, the energy, petrochemical industry, environmental protection, urban look, medical treatment, food and drink are also come into common people's daily life more and more.
The aging thalline that the effluent treatment and filtering device is mainly used in removing suspension in the waste water and comes off, traditional filter manhole adopts bolt to fix, contour installing/dismounting is inconvenience very, operating efficiency is low, in addition, the screw bolt and nut under the dismounting needs properly to place, if bolt and nut drops because of carelessness, then need to again pick up down to ground, increase workload.
Summary of the invention
The technical problems to be solved in the utility model provides the efficiently rotary manhole of effluent treatment and filtering device of a kind of conveniently opening and closing.
For solving the problems of the technologies described above, the technical solution of the utility model is: the rotary manhole of a kind of effluent treatment and filtering device, its innovative point is: comprise manhole mounting flange and manhole cover, the manhole mounting flange is welded on the filter head housings body sidewall, arrange on the manhole mounting flange along the radially-protruding articulated slab A of manhole mounting flange, manhole cover and manhole mounting flange match, and arrange on the manhole cover along the radially-protruding articulated slab B of manhole cover, and articulated slab B and articulated slab A through hole hinge axis are hinged; Be evenly distributed with some locking slots on the manhole cover periphery, some movable bolts corresponding with locking slot are set on the manhole mounting flange periphery, the rod end of movable bolt can wind perpendicular to the sagittal plane of manhole mounting flange and rotate; Manhole cover covers that the rod end of movable bolt rotatably embeds in the locking slot behind the manhole mounting flange, and locking nut is threaded on the movable bolt body of rod; Described movable bolt is connected by demountable structure with the manhole mounting flange.
Further, described demountable structure comprises bearing block, axle and bolt, groove milling on manhole mounting flange periphery, and bottom land bores bolt connecting hole, wears axle in the axis hole of movable bolt, and the two supports of axle is in bearing block, and bearing block is bolted on bottom land.
Further, be milled with seal groove on the flange face of described manhole mounting flange, seal groove is embedded with sealing ring.
The utility model has the advantage of: in the time of need to opening manhole cover, by the rotational lock nut, movable bolt is outwards rotated the disengaging locking slot get final product, need not to dismantle fully locking nut and bolt, reduce workload; Otherwise then carry out during the locking manhole cover, easy installation and removal is quick.

The specific embodiment
As shown in Figure 1, 2, 3, comprise manhole mounting flange 1, manhole cover 2, articulated slab A3, articulated slab B4, hinge axis 5, movable bolt 6, locking nut 7, bearing block 8, axle 9 and bolt 10.
Shown in Fig. 4,5, above-mentioned manhole mounting flange 1 is welded on the filter head housings body sidewall, arrange on the manhole mounting flange 1 along manhole mounting flange 1 radially-protruding articulated slab A3, manhole cover 2 matches with manhole mounting flange 1, arrange on the manhole cover 2 along manhole cover 2 radially-protruding articulated slab B4, articulated slab B4 and articulated slab A3 through hole hinge axis 5 are hinged.
Be evenly distributed with some locking slots on manhole cover 2 peripheries, some movable bolts corresponding with locking slot 6 are set on manhole mounting flange 1 periphery, the rod end of movable bolt 6 can wind perpendicular to the sagittal plane of manhole mounting flange 1 and rotate.
The rod end that manhole cover 2 covers manhole mounting flange 1 rear movable bolt 6 rotatably embeds in the locking slot, and the locking nut 7 that is threaded on movable bolt 6 bodies of rod, movable bolt 6 and manhole mounting flange 1 are connected by demountable structure.
Demountable structure comprises bearing block 8, axle 9 and bolt 10, groove milling on manhole mounting flange 1 periphery, and bottom land bores bolt connecting hole, wears axle 9 in the axis hole of movable bolt 6, and the two supports of axle 9 is in bearing block 8, and bearing block 8 is fixed on bottom land by bolt 10.
In addition, be milled with seal groove at the flange face of manhole mounting flange 1, seal groove is embedded with sealing ring.
Operation principle: when closing manhole, upset manhole cover 2 is so that manhole cover 2 is close to the flange face of manhole mounting flange 1, rotate movable bolt 6, so that the rod end of movable bolt 6 embeds locking slot, screw locking nut 7, by locking nut 7 and movable bolt 6 manhole cover 2 lockings are got final product; When opening manhole, unclamp locking nut 7, get final product so that movable bolt 6 is communicated with locking nut 7 outside counter-rotation.
