Description
Technical field
The invention belongs to a kind of water-treatment technology field, specifically for the facility of the desanding of the rain of pipeline, channel, flood, sewage etc., a kind ofly by precipitation, carry out separated device, particularly a kind of rotational flow grit chamber with guide shell containing sand grains in sand sewage or rainwater.Also can be for carrying the desanding of water body in various pipelines, channel.
Background technology
In city, a large amount of sewage, rainwater and other water bodys all will lean on underground piping to carry or discharge.In these water bodys, often contain silt particle, these silt particles need from water body, to remove in time, otherwise not only affect the clean and quality of water body, but also easily by line clogging, cause the damage of pipeline and surface structures.In sewage treatment plant, if larger particles silt not removed, also will cause silting up of subsequent treatment facility, and cause disposal ability to decline, the problems such as equipment attrition, the safe and stable operation of harm sewage treatment plant.For a long time, people have proposed many water body desanding technology.Rotational flow grit chamber is the structure comparatively generally adopting at present, can remove to a certain extent the silt particle in water body.For example Chinese patent ZL 02220513.6, " a kind of rotational flow sand sinking device ", Chinese patent ZL200820206062.8, the Bi Shi rotational flow grit chamber of " desander for rotational flow grit pit " and U.S. Smith & Loveless company.Their common ground is: a cylindric pond body is set, an impeller is installed in body bottom, pond, the rotation by impeller promotes current, brings out center, current direction pond and converges, and makes sludge settling in the sand collecting hopper of pond central lower.Their common shortcomings are: the first, rotatablely moving of impeller is easy to make the sand grains having precipitated to disperse, and reduce sand grains precipitation removal effect; The second, impeller is open design, impeller promotes current and brings out mobile that Xiang center converges, owing to not having, the constraint effect of solid boundaries is strong not, and the 3rd, because wheel speed is low, rotatablely move obvious not to the organic soil washing adhering on sand grains.Therefore, need to improve prior art.
Summary of the invention
The present invention, in order to solve the problems of the technologies described above, proposes a kind of rotational flow grit chamber with guide shell, and this setting pot is provided with the guide shell of novel structure, and it is more reasonable that the position of impeller arranges, and greatly improved the effect of desanding.
The present invention takes following technical scheme:
A kind of rotational flow grit chamber with guide shell, be provided with main tank body, the pool wall of this main tank body is cylindrical shape, one side of Qi Chi bottom centre is provided with water inlet and is communicated with canal for water conveyance water inlet one end, on the pool wall of main tank body, the same side of Chi bottom centre, the oblique upper of described water inlet is provided with delivery port and is communicated with canal for water conveyance water outlet one end, it is characterized in that: in main tank body, on pool wall, lean on into, delivery port one side is provided with dividing plate, this dividing plate is horizontally disposed with, described water inlet is below dividing plate, described delivery port is above dividing plate, this dividing plate is semicircle, its outer edge is closely connected with pool wall, bottom centre place at main tank body is provided with sand collecting hopper, the top of this sand collecting hopper is provided with a columnar guide shell, the diameter of this guide shell is greater than described sand collecting hopper diameter, guide shell is fixed on the top of sand collecting hopper along upper support member the end of by, at the bottom of guide shell along and the pond of main tank body at the bottom of between leave gap, guide shell bottom is the thick barrel of main body, upper end is provided with the thin barrel that diameter is less, the end opening of thin barrel is tightly connected by the suitable for reading of connecting plate and thick barrel, the upper port place of thin barrel is fixed with a hollow shaft, this hollow shaft lower end periphery is provided with an impeller in thin barrel, and the blade construction of impeller is: during rotation, to main tank body top, promote water, in hollow shaft, be provided with a sediment transport pipe, the lower port of this sediment transport pipe is communicated with the airlift pump that promotes upward silt particle or slag stock pump in being located at sand collecting hopper, described hollow shaft and a controllable motor transmission link.
The upper end of described thick barrel be provided with one for detection of guide shell in the sample suction pipe that draws water of water body.By this suction pipe, can extract easily water body sample in guide shell, understand silt particle and promote situation, be convenient to regulate exactly at any time the rotating speed of controllable motor and impeller, guarantee silt particle sedimentation better.
The running of setting pot of the present invention: enter main tank body containing sand sewage or rainwater along inlet channel or channel, under the pool wall constraint of dividing plate and main tank body, rotate and flow and lifting, reach the top of dividing plate after rotating a circle, enter outlet canal; The sand grains that current carry is deposited on main tank body base plate under Action of Gravity Field; The flow direction pool wall on top under eddy flow centrifugal action, bottom water flow flows to center, pushes the sand grains being deposited on main tank body base plate to central area; The sand collecting hopper lower than main tank body that central area arranges, sand grains falls under gravity into wherein; After sand grains accumulation certain hour, airlift pump or the work of slag stock pump, be pumped into other device processing by sand grains and a certain amount of water along sediment transport pipe, and motor rotates in concentric with it thin barrel by decelerator and hollow shaft impeller; The blade of impeller at an angle to the horizontal direction, to the water generates lifting force that makes progress, causes on current direction and flows during rotation; Guide shell is divided into center and peripheral two regions by the water body in main tank body, the motion of impeller and the high flow rate in thin barrel can not produce large disturbance to peripheral current, but in guide shell bottom, current can accelerate to enter center by gap under the lifting force effect of impeller; By the rotational speed regulation of designing and calculating and motor and decelerator, make current upflow velocity in the thick barrel of central area be controlled at a certain specific flow velocity, assurance floating velocity can not be taken away by ascending current higher than the sand grains of this value, and enter sand collecting hopper in central area rolling, sinking, for example be less than the upflow velocity of 0.02m/s, the sand grains that can make diameter be greater than 0.2mm is trapped in guide shell, finally falls into sand collecting hopper after rolling; Sand grains rolls and also the organic matter sticking on sand grains can be eluted in guide shell, reduces the load of the follow-up equipment that shakes out.
Beneficial effect of the present invention:
The first, the castering action of impeller is owing to there being the effect of contraction of barrel to strengthen flowing that main tank body bottom inwardly converges, and the sand grains that collecting precipitation gets off better prevents its deposition or again suspends and cause and disperse;
The second, the interior flow velocity promoting of thick cylinder is controlled, guarantees that large sand grains can not stirred from cylinder and fly ease by impeller;
Three, in thick cylinder, the rolling effect of sand grains has increased washed-out sand effect.
Four, guide shell is simple in structure, not high to shape, positional precision and sealing requirements, so manufacture craft is simple, consumable material is few, can be used for existing setting pot transformation, also can be used for newly-built setting pot, has practical extending application value.
