Abstract
The utility model provides a rotational flow sedimentation tank, which comprises a tank body and a central barrel, wherein the central barrel is arranged inside the tank body; the central barrel is arranged above a residue funnel through a support column; and an iron sheet ditch intake water flowing groove is inserted into the upper part of the central barrel along the tangential direction of the central barrel. The sedimentation tank is characterized in that a flow adjusting plate is arranged on the support column; and a gap is reserved between the flow adjusting plate and the inner wall of the residue funnel. According to the sedimentation tank, the oxidation iron sheet in the sedimentation area slides into the residue funnel along the gap between the flow adjusting plate and the residue funnel; a water absorbing well in an existing rotational flow sedimentation tank is omitted; the sedimentation area and the water absorbing well are combined integrally; the area of the sedimentation area is enlarged; the retention period of water is increased; the content of the oxidation iron sheet at the outtake water of the sedimentation area is reduced; the abrasion of the pump is reduced greatly; the change period of quick-wear parts is prolonged; the maintenance expense of the equipment is reduced; the later treatment load is reduced; and meanwhile, the working intensity of operation personnel is reduced and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of deposition structures that are used for production wastewater treatment, is specifically related to a kind of cyclone sediment pond.
Background technology
Metallurgical Factory needs to use a large amount of water that equipment is cooled off in continuous casting, steel rolling production process, and water contacts the back with base, plate, pipe, rod, line, the section bar of equipment and high temperature contaminated, and a large amount of iron scales gets in the cooling water.At present, precipitation mode is adopted in the processing of this factory effluent, promptly adopt the mode in scale pit and cyclone sediment pond to carry out precipitation process, the iron scale of post precipitation adopts the mode of grab bucket to remove.Existing cyclone sediment pond comprises the pond body, is arranged on central tube and the outer settling zone of central tube in the body of pond, and is provided with independently absorbing well, absorption well in the settling zone, gets into absorbing well, absorption well behind factory effluent process central tube, the settling zone, is pumped to the next stage processing structures at last.Because the water through post precipitation still contains certain iron scale, can precipitate behind the absorbing well, absorption well of these iron scales entering settling zones, cause the absorbing well, absorption well deposition, thereby cause wearing and tearing water pump.For fear of the wearing and tearing of deposition to water pump, need operating personnel regularly the mud of absorbing well, absorption well to be cleared up, two weeks will be cleared up once usually, and not only labour intensity is big, and influences normally carrying out of producing.
The utility model content
The purpose of the utility model is to provide a kind of cyclone sediment pond of simple in structure and not deposition.
The purpose of the utility model is to realize like this; A kind of cyclone sediment pond; Comprise that Chi Tihe is arranged on the central tube in the body of said pond, said central tube is arranged on above the slag bucket through support column, and iron sheet ditch water inlet chute inserts central tube top along said central tube tangential direction; It is characterized in that: said support column is provided with cowling panel, and leaves the slit between said cowling panel and the said slag bucket inwall.
For the iron scale that gathers on the cowling panel is slipped in the slag bucket smoothly, the slit between above-mentioned cowling panel and the slag bucket inwall is not less than 800mm.
Above-mentioned cowling panel is a perforated plate.
In order to guarantee the setting angle of cowling panel, the angle between above-mentioned support column and the horizontal plane is not less than 45 °.
After factory effluent gets into central tube; Current are eddy flow from top to bottom; Most of iron scale is deposited in the slag bucket, and current are up along the cowling panel that is arranged on the support column, and are assigned to the settling zone equably; The iron scale of settling zone deposition at first gathers on the cowling panel, is slipped in the slag bucket through the slit between cowling panel and the slag bucket inwall then; Water through post precipitation directly is pumped into the next stage processing structures by water pump; Iron scale in the slag bucket is removed with grab bucket and is got final product.
The utlity model has following beneficial effect, the central tube of the utility model is arranged on above the slag bucket through support column, be provided with on the support column cowling panel and and the slag bucket inwall between leave the slit so that the iron scale of settling zone slips into slag bucket; Cancel the absorbing well, absorption well in the existing cyclone sediment pond, settling zone and absorbing well, absorption well have been united two into one, enlarged the area of settling zone; Increase the time of staying of water, made the iron scale content of settling zone water outlet reduce the wearing and tearing that alleviated water pump significantly; Prolong the replacement cycle of consumable accessory, reduced the maintenance of equipment expense, alleviated the subsequent treatment load; Simultaneously also alleviate labor intensity of operating personnel, improved operating efficiency.

The specific embodiment
Embodiment, a kind of cyclone sediment pond comprises the pond body; Being provided with central tube 2 in the body of pond, is settling zone 6 outside the central tube 2, and central tube 2 is arranged on above the slag bucket 5 through support column 3; Angle between support column 3 and the horizontal plane is equal to or greater than 45 °, and iron sheet ditch water inlet chute 1 inserts central tube 2 tops along central tube 2 tangential directions, and support column 3 is provided with cowling panel 4; Leave the slit of minimum 800mm between cowling panel 4 and slag bucket 5 inwalls, cowling panel 4 is a perforated plate.
After factory effluent gets into central tube 2 from iron sheet ditch water inlet chute 1; Current are eddy flow from top to bottom; Most of iron scale is deposited in the slag bucket 5, and current are up along the cowling panel 4 that is arranged on the support column 3, are assigned to settling zone 6 equably; The iron scale of settling zone 6 depositions at first gathers on the cowling panel 4, is slipped in the slag bucket 5 through the slit between cowling panel 4 and slag bucket 5 inwalls then; Water through post precipitation directly is pumped into the next stage processing structures by water pump; Iron scale in the slag bucket 5 is removed with grab bucket.
