Described water inlet pipe is provided with screwed pipe joint, is connected with pipeline by described screwed pipe joint.
Described housing upper end is provided with suspension ring, is suspended in Chi Dingshang by described suspension ring, is convenient to installation and removal simultaneously.
The beneficial effects of the utility model are:
1, a kind of sedimentation basin central draft tube of the utility model by after water inlet pipe successively through intake chamber, cross hydroecium and water-supplying chamber, and cross-sectional area increases successively, and make flow velocity more and more less, current are more and more stable;
2, a kind of sedimentation basin central draft tube of the utility model is provided with cowling panel and lower cowling panel, reduces impact load further by the effect of cowling panel;
3, a kind of sedimentation basin central draft tube of the utility model is provided with baffle plate, baffle plate is connected with housing by spring, and when apopore flow velocity is excessive, current meeting impact baffle plate also makes baffle plate move down, current flow out from the space of baffle plate and housing simultaneously, reduce impact load.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sedimentation basin central draft tube of the utility model.
In figure: 1 is water inlet pipe, 2 is housing, and 3 is intake chamber, and 4 was hydroecium, and 5 is water-supplying chamber, and 6 is upper cowling panel, and 7 is lower cowling panel, and 8 is baffle plate, and 9 is spring, and 10 is apopore, and 11 is screwed pipe joint, and 12 is suspension ring.
Detailed description of the invention
Below in conjunction with Fig. 1, the utility model is further illustrated, but the utility model protection domain does not limit to described content.
It mainly comprises water inlet pipe 1 and housing 2, water inlet pipe 1 is in inverted L-shaped, water inlet pipe 1 is arranged on the upper end, left side of housing 2, and the outlet of water inlet pipe 1 in housing 2 inside upward, housing 2 inside is divided into intake chamber 3, cross hydroecium 4 and water-supplying chamber 5, intake chamber 3 and excessively hydroecium 4 are separated by upper cowling panel 6, cross hydroecium 4 to be separated by lower cowling panel 7 with water-supplying chamber 5, water-supplying chamber 5 has baffle plate 8, the length of baffle plate 8 is greater than lower cowling panel 7, the length of lower cowling panel 7 is greater than cowling panel 6, baffle plate 8 is flexibly connected by spring 9 with the sidewall of water-supplying chamber 5, when hydraulic blow is excessive, current are by impact baffle plate 8, baffle plate 8 is moved down, play the effect of buffering, simultaneously water can flow out from baffle plate 8 and the space of housing 2, the sidewall of water-supplying chamber 5 is uniform-distribution with several apopores 10, water flows to sedimentation basin from apopore 10, water inlet pipe 1 is communicated in intake chamber 3, upper cowling panel 6 is perpendicular with the sidewall of intake chamber 3, the sidewall of lower cowling panel 7 and excessively hydroecium 4 is 40-80 degree angle, baffle plate 8 is 20-60 degree angle with the sidewall of water-supplying chamber 5, and baffle plate 8 and the angle of the sidewall of water-supplying chamber 5 are less than the angle of the sidewall of lower cowling panel 7 and mistake hydroecium 4, cross-sectional area is increased successively, thus make flow velocity more and more less, current are more and more stable, intake chamber 3 is cylindrical, cross hydroecium 4 and water-supplying chamber 5 in truncated cone-shaped, water inlet pipe 1 is provided with screwed pipe joint 11, be connected with pipeline by screwed pipe joint 11, housing 2 upper end is provided with suspension ring 12, Chi Dingshang is suspended in by suspension ring 12, be convenient to installation and removal simultaneously.
