Detailed Description
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
The inventor makes the following improvement in order to solve the problem that the filter screen is easily blocked when primary treatment is performed on the construction site sewage in the prior art.
A primary treatment device for construction site sewage comprises a container 1, wherein the container 1 is used as a filter cavity, a feed inlet 2 is formed above the container 1, the feed inlet 2 is used for introducing sewage, and the inner diameter of the feed inlet 2 is larger in consideration of primary treatment and more stones or sands. And a discharge port 3 is arranged below the feed port 2 and used for discharging the sewage after primary treatment. The wall of the container 1 has a certain thickness.
The inside swing mechanism that is provided with of container 1, swing mechanism transmission is connected in the filter screen, and during operating condition, sewage enters into the inside filter screen of container 1 through feed inlet 2, and the filter screen is in the state of swing and vibration under swing mechanism's transmission, and sewage comes out through discharge gate 3 discharges from the filter screen again, filters gravel and sand in the filter screen, and the filter screen of vibration is garrulous with silt vibration, flows along with the rivers.
Further, the filter screen includes: the filter screen comprises a placing frame 4, a clamping ring 5 which is fixed at the top of the placing frame 4 and is turned outwards, a placing plate 6 which is fixed at the bottom of the placing frame 4, and a filter screen body 7 which is placed inside the placing frame 4; wherein, the clamping ring 5 is movably clamped in the container 1.
Because the filter screen has a certain blocking effect on the water flow, the phenomenon of crowding or reverse flow can occur, as shown in fig. 2, the filter screen body 7 and the placing frame 4 have the same structure and are both inverted round tables, and the filter screen has an inclined angle, so that the cross-sectional area of the water flow is increased.
In order to realize the swing of the filter net, as shown in fig. 3 and 4, the swing mechanism includes: the container comprises a bracket 8 fixed inside the container 1, a waist-shaped groove 9 formed in the bracket 8 along the length direction of the bracket 8, a fixed ring 10 fixed inside the bracket 8, and a revolving component arranged inside the fixed ring 10; the revolving component is in transmission connection with the placing plate 6.
The turn-around assembly includes: the transmission is connected 14 rings of gears 11 in the retainer plate 10 are installed the pivot 12 of 8 bottom central points of support department of putting, fixed connection are in swinging boom 13 in the pivot 12 is installed swinging boom 13 of swinging boom 13 active end department, with gear 14 is coaxial coupling's linking arm 16, and fixes 16 terminal connecting cylinder 15 of linking arm, gear 14 with 14 rings of gears 11 intermeshing, the top of connecting cylinder 15 is passed waist type groove 9 and with the transmission of the centre of a circle department of placing board 6 is connected. The rotating shaft 12 is connected with a rotating motor in a transmission manner, and the rotating motor is arranged on the container 1.
Namely, the swing mechanism realizes that the gear 14 rotates around the rotating shaft 12 by the rotation of the rotating arm 13 in combination with the meshing of the gear 14 and the ring 11 of the internal gear 14, and then the connecting cylinder 15 is combined with the limitation of the waist-shaped groove 9, the connecting cylinder 15 in the annular groove on the surface of the gear 14 reciprocates along the waist-shaped groove 9, namely, the placing plate 6 in transmission connection with the connecting cylinder 15 is also driven to do reciprocating motion, so that the whole filter screen is driven to do reciprocating motion, and in the motion process, the filter screen body 7 can vibrate under the action of inertia. Meanwhile, in order to prevent the clamping ring 5 from being separated from the container 1, sewage is discharged without passing through the filter screen. The diameter of the gear wheel 14 is therefore equal to the length of the connecting arm 16, which is smaller than the width of the ring in which the snap ring 5 is located. The wall thickness of the container 1 is greater than the diameter of said gear 14.
