Abstract
The utility model discloses an energy-dissipation water inlet rotational flow sedimentation tank. The energy-dissipation water inlet rotational flow sedimentation tank comprises a rotational flow sedimentation tank body with a sheet iron trench, and a center cylinder is arranged at the center of the rotational flow sedimentation tank body. The energy-dissipation water inlet rotational flow sedimentation tank is characterized in that a water power energy-dissipation section is arranged between the sheet iron trench and the center cylinder, the water power energy-dissipation section is a sluice with a slope extending towards the center cylinder, the sluice is arranged along the direction of water flow of the sheet iron trench, the sluice and a tangent line of the center cylinder are intersected, and the slope of the sluice is larger than 20 degrees. According to the energy-dissipation water inlet rotational flow sedimentation tank, the velocity produced when the water flows into the center cylinder is reduced, the rotating water can not enable a grab bucket to rotate, slag removing operation is facilitated, operation speeds are accelerated, and the service life of a steel wire rope of the grab bucket is prolonged.
Description
Technical field
The utility model relates to a kind of precipitation structures for the production of wastewater treatment.
Background technology
Metallurgical works needs to use a large amount of water to carry out the cooling of equipment in continuous casting, steel rolling production process, it is contaminated after water contacts with base, plate, pipe, rod, line, the section bar of equipment and high temperature, in a large amount of iron scale water inlet cooling waters, the processing of this factory effluent is adopted the mode of precipitation, namely adopt the mode of scale pit and rotational flow settling pond to carry out precipitation process, the iron scale after the precipitation adopts the mode of grab bucket to remove.When adopting rotational flow settling pond as the precipitation structures, because the water inlet tangential direction enters the rotational flow settling pond central tube, cause the water flow rotary in the central tube, improved the effect of precipitation, but in the process of grab bucket scarfing cinder, the current of rotation cause the grab bucket rotation, cause that the grab bucket steel cable twines, and then can't carry out the scarfing cinder operation.
The utility model content
The purpose of this utility model provides a kind of energy dissipating water inlet rotational flow settling pond, can reduce central tube water flow rotary speed.
To achieve these goals, by the following technical solutions: a kind of energy dissipating water inlet rotational flow settling pond, comprise the rotational flow settling pond with iron sheet ditch, the center of rotational flow settling pond has central tube, it is characterized in that: be provided with waterpower energy dissipating section between described iron sheet ditch and the central tube, wherein the chute of waterpower energy dissipating Duan Weiyi bar gradient direction slope aspect central tube.
Described chute is arranged along iron sheet ditch water (flow) direction, and is intersected with the central tube tangent line.
The gradient of described chute is greater than 20 °.
The length of described chute is not shorter than 1.5m.
Flow velocity when the utility model reduces current and enters central tube, the current of rotation can not cause the grab bucket rotation, are convenient to the scarfing cinder operation, have accelerated operating speed, have prolonged steel wire rope of grab bucket service life.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As depicted in figs. 1 and 2, a kind of energy dissipating water inlet rotational flow settling pond, comprise the rotational flow settling pond 1 with iron sheet ditch 2, the center of rotational flow settling pond 1 has central tube 3, is provided with waterpower energy dissipating section between iron sheet ditch 2 and the central tube 3, wherein the chute 4 of waterpower energy dissipating Duan Weiyi bar gradient direction slope aspect central tube, wherein chute 4 is arranged along iron sheet ditch water (flow) direction, and intersect with central tube 3 tangent lines, the gradient of chute 4 is 40 °, and length is 2m.
The utility model is by arranging an energy dissipating section before the iron sheet ditch enters the rotational flow settling pond central tube, the energy of the rapid current of iron sheet ditch is eliminated, be controlled in certain scope so that enter the water velocity of rotational flow settling pond central tube, although rotation, but speed is slower, can not cause the grab bucket rotation, thereby reach the purpose of smooth scarfing cinder.
