Utility model content
The purpose of this utility model is in view of the above shortcomings of the prior art, to propose a kind of high density sewage precipitation device, Mixing efficiency can be improved by the device, improve sludge and concentration is discharged, reduce reagent cost, reduce secondary pollution.
The technical solution of the utility model is: a kind of high density sewage precipitation device, including the stirring being connected in series with each other Pond, dosing pond, sedimentation basin and clear water reserviors connect the water inlet pipe being arranged on stirring pool, connect the water outlet being arranged on clear water reserviors Pipe, is arranged in stirring pool and speed reducer, support, blade and agitating shaft in dosing pond, and speed reducer in sedimentation basin, snail is arranged in Roller box, main shaft, stirring rod and spoil disposal blade are constituted;It is characterized by: the high density sewage precipitation device is also by mixing arrangement It is constituted with dehydration device;The bottom in the stirring pool and dosing pond is equipped with the drug feeding pipeline that connection communicates, and the mixing arrangement is set It sets in the drug feeding pipeline, the mixing arrangement is made of multiple mixed cells for intersecting board plug structure;The dehydration device The bottom of sedimentation basin is set, and the dehydration device is made of dehydration cylinder, setting in the intracorporal screw rod of dehydration tube and blade, described Screw rod is connected to a fixed with the main shaft in sedimentation basin, and the discharge port for being dehydrated cylinder is divided into two ports, and one of port passes through Coagulation sludge pipe is connect with water inlet pipe, another port is connected with mud mouth.
In vertically arranged, blade diameter is gradually incremented by the dehydration device from top to bottom.
The quantity of the mixed cell is no less than 2, and mixed cell welding is arranged on the horizontal segment of drug feeding pipeline.
The coagulation sludge pipe is equipped with check valve and pressurizing valve.
The utility model has the following beneficial effects: a kind of high density sewage precipitation device provided by the utility model, in tradition Dehydration device and mixing arrangement are increased on the basis of stirring pool, dosing pond, sedimentation basin and clear water reserviors, is added in mud discharging mouth One branch circuit allows partial sludge to flow back into coagulation stirring pool and participates in coagulation, reduces medicament and uses, increases coagulation effect, make miscellaneous Flowing is disorderly become uniformly by power stirring without chapter, thick dilute irregular raw water, mixing sufficiently, improves settling velocity and precipitating effect The sludge concentration of fruit, discharge is higher, reduces mud discharging bring secondary pollution.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram.
In figure: water inlet pipe 1, blade 2, support 3, stirring pool 4, agitating shaft 5, the first mixed cell 6, drug feeding pipeline 7, second Mixed cell 8, speed reducer 9, dosing pond 10, sedimentation basin 11, stirring rod 12, coagulation sludge pipe 13, main shaft 14, spoil disposal blade 15, Speed reducer 16, worm gear case 17, inclined tube 18, clear water reserviors 19, your defeated pipeline 20, dehydration cylinder 21, mud mouth 22, bottom of pond 23, water outlet Pipe 24.
Specific embodiment
