Abstract
The utility model relates to a kind of circumference efficient sedimentation tanks, it includes circular settling tank and the rectangular sedimentation basin that is connected with circular settling tank by discharge orifice, priming reservoir is provided in rectangular sedimentation basin, the rectangular sedimentation basin is connected with priming reservoir by through-hole, and promotion water pump is provided on priming reservoir；The utility model is in such a way that circular settling tank and rectangular sedimentation basin combine, and circular settling tank is as rotational flow settling pond, and rectangular sedimentation basin is as horizontal sedimentation tank.Water is first precipitated in circular settling tank, remove the iron scale of larger particles, then water outlet is flowed into rectangular sedimentation basin and carries out advection sedimentation, remove the iron scale of smaller particle, it is entered in priming reservoir after removing oil slick using oil skimming machine, next stage water processing establishment is then pumped to by promotion water.
Description
Technical field
The utility model relates to field of water treatment equipment, specifically a kind of circumference efficient sedimentation tank.
Background technique
Continuous casting turbid circulating water, the steel rolling turbid circulating water of traditional iron and steel enterprise use horizontal sedimentation tank or rotational flow settling pond to carry out level-one
Precipitating.Horizontal sedimentation tank impact resistance is poor, water influence of fluctuations sedimentation effect, and especially when grabbing slag, water is in turbulent flow
State is unfavorable for precipitating, poor processing effect；Cyclone sediment tank depth is big, and general depth is applied in 18 ~ 24m using underground open caisson
Work, vulnerable to geological hydrology and Effect of Underground Water Level, difficulty of construction is big, and uncertain factor is more, and investment cost is high.
Utility model content
It is good that the technical problem to be solved by the utility model is to provide a kind of sedimentation effects, can effectively remove water oxygen
The circumference efficient sedimentation tank of the impurity such as iron sheet, greasy dirt.
The technical scheme adopted by the utility model is a kind of circumference efficient sedimentation tank comprising circular settling tank and
The rectangular sedimentation basin being connected with circular settling tank by discharge orifice is provided with priming reservoir in rectangular sedimentation basin, described rectangular
Sedimentation basin is connected with priming reservoir by through-hole, and promotion water pump is provided on priming reservoir.
The utility model is provided with water inlet on the side wall of the circular settling tank, the water inlet direction of the water inlet with
The inner wall of circular settling tank is tangent.
The utility model is provided with water pipe on the promotion water pump, and the water pipe extend into the bottom of priming reservoir.
The good effect of the utility model are as follows: the side that the utility model uses circular settling tank and rectangular sedimentation basin to combine
Formula, circular settling tank is as rotational flow settling pond, and rectangular sedimentation basin is as horizontal sedimentation tank.Water first carries out in circular settling tank
Precipitating, removes the iron scale of larger particles, and then water outlet is flowed into rectangular sedimentation basin and carries out advection sedimentation, removes smaller particle
Iron scale, using oil skimming machine remove oil slick after enter in priming reservoir, next stage water process is then pumped to by promotion water
Facility.The utility model combines the characteristics of high treating effect and horizontal sedimentation tank depth as shallow of rotational flow settling pond, and the two is had
Machine is fused together, and has high-efficient, the remarkable advantage of low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the utility model water inlet structure schematic diagram.
Specific embodiment
As shown in attached drawing 1,2, the utility model includes circular settling tank 1 and passes through 8 phase of discharge orifice with circular settling tank 1
The rectangular sedimentation basin 2 of connection, circular settling tank 1 play the role of rotational flow settling pond, and rectangular sedimentation basin 2 plays horizontal sedimentation tank
Effect.Priming reservoir 4 is provided in rectangular sedimentation basin 2, the rectangular sedimentation basin 2 is connected with priming reservoir 4 by through-hole 3,
It is provided on priming reservoir 4 and promotes water pump 6.Two kinds of sedimentation basins are organically fused together by the utility model, and deposition efficiency is higher,
The impurity such as iron scale, the greasy dirt in waste water can be effectively removed, and cost is lower.
Water inlet 7, the lateral wall of the water inlet 7 and round precipitating are provided on the side wall of the circular settling tank 1
The inner wall in pond 1 is tangent.So that water enters central tube along the circular inner wall tangential direction of circular settling tank 1, water fast speed,
In 2 ~ 3m/s, water rotates in central tube, first is that playing the role of energy dissipating；Second is that precipitation is played, the iron scale warp in water
Eddy flow and play the role of accelerating settling velocity, deposition efficiency is high, and removal rate is up to 70%.
Circular settling tank water outlet overflows to rectangular sedimentation basin 2 from discharge orifice 8, and rectangular sedimentation basin 2 belongs to horizontal sedimentation tank, carefully
Little particle continues to precipitate, removal rate 20%；Oil slick is swum on liquid level, and liquid level is more tranquil to be stablized, convenient for that will be floated using oil receiving equipment
Oil is removed.
Water pipe 5 is provided on the promotion water pump 6, the water pipe 5 extend into the bottom of priming reservoir 4, and promoting water pump 6 will
Water in priming reservoir send to next stage water processing establishment and is further processed.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by embodiment is stated to modify or equivalent replacement of some of the technical features；And these are repaired
Change or replaces, the spirit and scope for the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution.
