Abstract
The utility model provides a spiral -flow type inspection shaft comprises inlet tube, outlet pipe, micro porous filtration board, sediment basket, inspection shaft pit shaft, manhole cover, sediment basket handle, inlet tube and outlet pipe lie in the both sides of inspection shaft respectively, are provided with the micro porous filtration board on one side of the outlet pipe, and inspection pit shaft and sediment basket are cylindrically to set up the sediment basket of removable formula below the inspection shaft, be convenient for handle the residue thing. The utility model provides a debris plug the pipe's problem in the dirty waste water, make debris hold back in the sediment basket of inspection shaft, improved the operational safety of pipe network.
Description
Technical field
The utility model belongs to municipal drainage pipeline design field, more particularly, to a kind of spiral-flow type inspection shaft.
Background technology
Inspection shaft is located at pipeline intersection, turning, caliber or gradient change and on straight line pipeline section every certain
At distance, it is easy for making regular check on auxiliary construction.The a large amount of debris carried in sewage, rainwater can cause the blocking of pipeline, shadow
The operation of the whole drainage pipeline networks of sound, it is therefore necessary to which necessary cleaning is carried out to the debris in water.
The content of the invention
The technical problems to be solved in the utility model is the drawbacks described above for overcoming prior art to exist, there is provided a kind of eddy flow
Formula inspection shaft.
The utility model solves the technical scheme that its technical problem adopted：
A kind of spiral-flow type inspection shaft, it is characterised in that by water inlet pipe 1, outlet pipe 2, micro-porous filtration plate 3, slag basket 4, inspection
Well shaft 5, manhole cover 6, slag basket handle 7 are constituted.
, respectively positioned at the both sides of inspection shaft, the stain disease in water inlet pipe 1 is along inspection shaft well for the water inlet pipe 1 and outlet pipe 2
5 tangential directions of cylinder flow into inspection shaft, form eddy flow.
The micro-porous filtration plate 3 is located at the side of outlet pipe 2, is made up of the aperture of some 3-10mm diameters, the dirt of eddy flow
Due to inertia, under by centrifugal action, the larger dirt of relative density is thrown toward pool wall to waste water, in Action of Gravity Field and micropore
Under the interception function of filter 3, proportion is larger, be retained down with diameter greater than the dirt particle of opening diameter, through retaining
Stain disease after filter flows out inspection shaft by outlet pipe 2.
The slag basket 4 is located at and checks bottom, and to hold the dirt that Jing is retained down, slag basket handle 7 is located at inspection shaft
The lower section of lid 6, inspection shaft is proposed by handle by slag basket, carries out the cleaning of slag basket.
The manhole shaft 5 is that stack shell is circular, and cylinder bottom is back taper, checks that pit shaft 5 is made of plastics.
The manhole cover 6 is truncated cone-shaped, is placed on inspection pit shaft 5.
The beneficial effects of the utility model are：The utility model provides a kind of spiral-flow type inspection shaft, the pit shaft of the inspection shaft
It is made of plastics, it is rounded, micro-porous filtration plate is installed in pit shaft, by eddy flow centrifugal force and micro-porous filtration plate crown_interception,
The debris in waste water are intercepted, debris are fallen in slag basket, realize the separation to debris in water, ensure that pipeline is not blocked, improve pipe
The safety in operation of net.
Description of the drawings
Fig. 1 is the utility model spiral-flow type inspection shaft generalized section.
Fig. 2 is the utility model spiral-flow type inspection shaft floor map.
Wherein：Water inlet pipe 1, outlet pipe 2, micro-porous filtration plate 3, slag basket 4, inspection pit shaft 5, manhole cover 6, slag basket handle 7.
Specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
According to Fig. 1, a kind of spiral-flow type inspection shaft, including water inlet pipe 1, outlet pipe 2, micro-porous filtration plate 3, slag basket 4, inspection pit shaft
5th, manhole cover 6, slag basket handle 7 are constituted, and the water inlet pipe 1 and outlet pipe 2 are respectively positioned at the both sides of inspection shaft body, inspection shaft
Cylinder 5 and slag basket 4 are all cylinders, and slag basket handle 7 is welded into one with slag basket 4.
Stain disease flows into inspection shaft by water inlet pipe 1, and because water inlet pipe 1 and manhole shaft 5 are in tangent line, the dirt of inflow is given up
After water tangentially flows, eddy flow is formed, under the action of the centrifugal force, the larger dirt of relative density is thrown toward pool wall, stain disease stream
Jing micro-porous filtration plates 3, are provided with the aperture of some 3-10mm diameters on micro-porous filtration plate 3, in the case where micro-porous filtration plate 3 is intercepted, proportion
It is larger, be retained down with diameter greater than the dirt particle of opening diameter, the stain disease after retention is filtered is flowed by outlet pipe 2
Go out inspection shaft.
Debris under being intercepted by micro-porous filtration plate 3 are fallen in slag basket 4, manhole cover 6 are opened, by slag basket handle 7 slag
Outside the proposition inspection shaft of basket 4, the cleaning to debris is realized.
