Abstract
The utility model relates to a rotational flow debris basin. The rotational flow debris basin is composed of the rotational flow debris basin body and a spiral sand-water separator, and the rotational flow debris basin is characterized in that a mud inlet end of the spiral sand-water separator is arranged on the bottom of a sand hopper of the rotational flow debris basin body; and a mud outlet end of the spiral sand-water separator is provided with a mud discharging pipe, and a screw propeller is axially arranged in the rotational flow debris basin body. The rotational flow debris basin provided by the utility model has the advantages that the structure is simple, the installation is easy, and the desanding efficiency is effectively improved; the axial screw propeller can drive intake water and water flow in a pool to the pool center and then move upwards to form a circulating flow state, sand grains are slowly and horizontally pushed to an annular sand hopper port, organic matters attached on the sand grains are separate from the sand grains in the flat movement process so as to return back in waste water, rise along with the water flow and flow to a water outlet pipe along the ascending waterflow, and organic substances and peculiar smell in desilting are greatly reduced; and the spiral sand-water separator can separate silt on the bottom of the sand hopper, the sand-water separator does not need to be separately arranged, and the floor area is small.
Description
Technical field
The utility model relates to a kind of rotational flow grit chamber, belongs to the sewage disposal environmental technology field.
Background technology
In sewage disposal process, because contain silt in sewage, will affect the treatment effect of subsequent processing device, will sink collection in the pond as not processing, so need sand-catching apparatus, protect follow-up water treatment facilities.Rotational flow grit chamber adopts the forced vortex principle to reach the purpose of sand fallout, sewage enter be in line after straight inlet channel mobile, the turbulent fluctuation of water inlet is minimized, water inlet enters in the pond along rotational flow grit chamber periphery tangential direction, make it to produce wall attachment effect, formerly be deposited in sand grains at the bottom of canal along slope current to flat and be captured thereby make.Prior art employing air lift is promoted to grit water separator except sand pump, needs equipment more, and air lift needs compressed air except sand pump, and power consumption is higher, separately also needs independent installation grit water separator and supernatant more.Therefore need a kind of rotational flow grit chamber, can carry out simultaneously sand moisture from.
The utility model content
The purpose of this utility model is to provide a kind of rotational flow grit chamber, have simultaneously sand setting and sand moisture from characteristics.
The purpose of this utility model is achieved through the following technical solutions: a kind of rotational flow grit chamber, formed by rotational flow grit chamber and spiral grit water separator, and it is characterized in that: the mud inlet end of described spiral grit water separator is arranged on the sand hopper bottom of rotational flow grit chamber; The mud outlet end of described spiral grit water separator is installed discharge pipeline; Screw axially is installed in described rotational flow grit chamber.
The sand hopper of described rotational flow grit chamber is installed evacuated tube.
Further, the pool wall tangent line of described rotational flow grit chamber is installed into water pipe.
the utility model operation principle: after the sewage of sewage treatment plant is removed suspended particulate through fine fack, sewage enters in the pond through the pool wall tangent line of water inlet pipe along rotational flow grit chamber, in the rotational flow grit chamber center, one axial screw oar is housed, be used for guaranteeing the suitable rotation of all current in the pond, screw, entry deflector and water inlet current combine, will produce the circulation fluidised form, under the effect of circulation fluidised form, the effect of centrifugal force make sand grains to greatest extent with flat collision, and captured by current, and sand grains is in case become trapped on flat, the bottom speed that produces with regard to membership circulation fluidised form is pushed to central authorities, fall into sand hopper.Along flat when being pushed to the setting pot center, rotary blade will speed up flow when sand grains, makes lighter organic matter be raised and be back in the water outlet of setting pot and goes.When in sand hopper, the stored sand grains that has was abundant, the spiral grit water separator that sand grains is installed at the bottom of by the pond was isolated, and falls into go-cart from discharge pipeline.
The utility model compared with prior art has following advantage and beneficial effect: a kind of rotational flow grit chamber of the utility model, and this apparatus structure is simple, is easy to install, and can effectively improves desanding efficiency; Axial screw can be with water inlet and pool inner water stream to the pond heart, then make progress, form the circulation fluidised form, and slowly flatly push sand grains to the ring-shaped sand quarrel, the organic matter that is attached on sand grains breaks away from sand grains in flat motion process, come back in waste water, and rise with current, flow to outlet pipe, this has greatly reduced the appearance of contained organic substance and peculiar smell in the sand setting; The spiral grit water separator is isolated the silt of sand hopper bottom, does not need to arrange separately grit water separator, and floor space is little.
Description of drawings
Fig. 1 is sectional structure chart of the present utility model;
Fig. 2 is plane of the present utility model.
Mark and corresponding parts title in accompanying drawing: 1-rotational flow grit chamber, 2-sand hopper, 3-water inlet pipe, 4-outlet pipe, 5-screw, 6-railing, 7-cat ladder, 8-support, 9-evacuated tube, 10-spiral grit water separator, 11-discharge pipeline, 12-go-cart, 13-platform.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but embodiment of the present utility model is not limited to this.
Embodiment: as shown in Figures 1 and 2, the utility model is comprised of rotational flow grit chamber 1 and spiral grit water separator 10, it is characterized in that: the mud inlet end of described spiral grit water separator 10 is arranged on sand hopper 2 bottoms of rotational flow grit chamber 1; The mud outlet end of described spiral grit water separator 10 is installed discharge pipeline 11; Screw 5 axially is installed in described rotational flow grit chamber 1.
The sand hopper 2 of described rotational flow grit chamber 1 is installed evacuated tube 9.
Further, the pool wall tangent line of described rotational flow grit chamber 1 is installed into water pipe 3.
during the operation of the utility model device: after the sewage of sewage treatment plant is removed suspended particulate through fine fack, sewage enters in the pond through the pool wall tangent line of water inlet pipe along rotational flow grit chamber 1, in rotational flow grit chamber 1 center, one axial screw oar 5 is housed, be used for guaranteeing the suitable rotation of all current in the pond, screw 5, entry deflector and water inlet current combine, will produce the circulation fluidised form, under the effect of circulation fluidised form, the effect of centrifugal force make sand grains to greatest extent with flat collision, and captured by current, and sand grains is in case become trapped on flat, the bottom speed that produces with regard to membership circulation fluidised form is pushed to central authorities, fall into sand hopper 2.Along flat when being pushed to the setting pot center, rotary blade will speed up flow when sand grains, makes lighter organic matter be raised and be back in the water outlet of setting pot and goes.When in sand hopper 2, the stored sand grains that has was abundant, the spiral grit water separator 10 that sand grains is installed at the bottom of by the pond was isolated, and falls into go-cart 12 from discharge pipeline 11.
As mentioned above, just can realize well the utility model.
