Abstract
The utility model discloses a vertical flow sedimentation basin which comprises a basin body (1), a sludge hopper (2) arranged at the lower part of the basin body (1) and a water collection tank (3) arranged at the upper part of the basin body (1), wherein a sludge pipe (4) going out of the basin body (1) is arranged at the bottom of the sludge hopper (2); a central flow guide barrel (6) communicated with a water inlet pipe (5) is arranged in the basin body (1); a reflection cone 7 connected with the central flow guide barrel (6) is arranged at the lower side of the central flow guide barrel (6); and the conical angle of the reflection cone 7 is 25 to 40 degrees. According to the vertical flow sedimentation basin, the conical angle of the reflection cone is reduced, so that sludge on the conical surface of the reflection cone slides to the sludge hopper under the gravity and the impact of water flow and is difficult to deposit; and the vertical flow sedimentation basin has the characteristics of simple structure and good using effect and is suitable for popularization and use.
Description
Technical field
The utility model relates to water-treatment technology field, specifically a kind of vertical sedimentation tank for the treatment of waste water.
Background technology
Existing vertical sedimentation tank, the central draft tube downside that arranges in the body of pond is provided with reflection cone, but because the cone angle of reflection cone is excessive, so that easily deposition on the reflection cone, if process the vertical sedimentation tank that is similar to biochemical waste water, then after wastewater treatment after a while, because the deposition of reflection cone, the phenomenon that the sludge anaerobic come-up causes the water quality variation can occur, and can't reach the water treatment effect of expection.
Summary of the invention
The purpose of this utility model is the defective for prior art, and a kind of vertical sedimentation tank that solves the reflection cone deposition is provided.
The purpose of this utility model solves by the following technical programs:
A kind of vertical sedimentation tank, comprise the water leg that the top of sludge bucket that pond body, body bottom, pond arrange and pond body arranges, the bottom of sludge bucket is provided with leads to the external sludge pipe in pond, in the body of pond, be provided with the central draft tube that is connected with water inlet pipe, the downside of central draft tube is provided with coupled reflection cone, and the cone angle that it is characterized in that described reflection cone is 25 °～40 °.
The underrun connector of described reflection cone links to each other with the central draft tube of its upside, the bottom surface circumferentially-spaced of the lower end edge reflection cone of described connector.
The bottom surface of described reflection cone is positioned at the upside on edge on the sludge bucket.
Described central draft tube comprises the reducing cylinder of straight tube and its downside, and the lower end of straight tube links to each other with the sealing of the upper end of reducing cylinder and straight tube is connected with water inlet pipe.
The diameter of described reducing cylinder upper end is not less than the diameter of the diameter of straight tube and reducing cylinder lower end greater than the diameter of reducing cylinder upper end.
The lower end week side of described reducing cylinder links to each other with the bottom surface of reflection cone by connector.
The top of described pond body is provided with downflow weir, and the upper edge that described downflow weir is positioned at the inside circumference of water leg and downflow weir is higher than the bottom of water leg.
The utility model has the following advantages compared to existing technology:
The utility model diminishes by the cone angle with reflection cone so that drop on the reflection cone conical surface mud under the impact of gravity and current along conical surface landing to sludge bucket and be difficult for deposition, have characteristics simple in structure, that result of use is good, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations that the reflection cone of central draft tube of the present utility model and its downside links to each other.
Wherein: 1-pond body; 2-sludge bucket; 3-water leg; 4-sludge pipe; 5-water inlet pipe; 6-central draft tube; 7-reflection cone; 8-connector; 9-straight tube; 10-reducing cylinder; 11-downflow weir.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Shown in Fig. 1-2: a kind of vertical sedimentation tank, comprise pond body 1, the water leg 3 that the sludge bucket 2 that body 1 bottom in pond arranges and the top of pond body 1 arrange, be provided with downflow weir 11 on the top of pond body 1 in addition, the upper edge that this downflow weir 11 is positioned at the inside circumference of water leg 3 and downflow weir 11 is higher than the bottom of water leg 3, the bottom of sludge bucket 2 is provided with the sludge pipe 4 that leads to outside the pond body 1, in pond body 1, be provided with the central draft tube 6 that is connected with water inlet pipe 5, central draft tube 6 comprises the reducing cylinder 10 of straight tube 9 and its downside, the upper end sealing of the lower end of straight tube 9 and reducing cylinder 10 links to each other and straight tube 9 is connected with water inlet pipe 5, and the diameter of these reducing cylinder 10 upper ends is not less than the diameter of the diameter of straight tube 9 and reducing cylinder 10 lower ends greater than the diameter of reducing cylinder 10 upper ends; The downside of central draft tube 6 is provided with coupled reflection cone 7, the cone angle of this reflection cone 7 is set as 25 °～40 °, the underrun connector 8 of reflection cone 7 links to each other the bottom surface circumferentially-spaced of the lower end edge reflection cone 7 of connector 8 with the lower end week side of the reducing cylinder 10 of its upside.Be in addition the too urgent impact value sludge bucket 2 of current in the anti-central draft tube 6, so the bottom surface of reflection cone 7 has certain spacing between the upper edge of the bottom surface of the upside on edge on the sludge bucket 2 and reflection cone 7 and sludge bucket 2.
The utility model in use, sewage enters in the straight tube 9 of central draft tube 6 through water inlet pipe 5, flow velocity reduced gradually when the sewage in the straight tube 9 was flowed through reducing cylinder 10 downwards, sludge settling in the sewage is to reflection cone 7, the conical surface along reflection cone 7 is slipped in the sludge bucket 2, by sludge pipe 4 collection and treatments, sewage changes flow direction through the reflection of reflection cone 7 simultaneously, is spilled over to water leg 3 interior gravity flow water outlets by downflow weir 11 at last.The utility model diminishes by the cone angle with reflection cone 7, so that drop on reflection cone 7 conical surfaces mud under the impact of gravity and current along conical surface landing to sludge bucket in 2 and be difficult for deposition, have characteristics simple in structure, that result of use is good, suitable promoting the use of.
The technology that the utility model does not relate to all can be realized by prior art.
