Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a water distribution device and an inclined tube sedimentation tank. Background Art

[0002] Inclined tube sedimentation tank usually refers to a sedimentation tank with inclined tubes in the sedimentation area. The assembly forms are generally divided into two types: inclined tubes and branch pipes. In the sedimentation area of ​​the horizontal flow or vertical flow sedimentation tank, inclined parallel tubes or parallel pipes (sometimes honeycomb fillers can be used) are used to divide it into a series of shallow sedimentation layers. The treated and settled sludge moves and separates in each shallow sedimentation layer, further achieving the purpose of mud and water separation.

[0003] The inclined tube sedimentation tank is mainly based on the shallow tank principle. Under the condition of a certain effective volume of the sedimentation tank, the larger the area of ​​the sedimentation tank, the higher the sedimentation efficiency of the sedimentation tank, and the shallower the sedimentation tank, the shorter the sedimentation time. In order to achieve a certain sedimentation efficiency, the traditional inclined tube sedimentation tank generally occupies a larger area.

[0004] In actual engineering use, water treatment equipment is mostly renovation projects. Even the space reserved for new projects is limited. In order to meet the on-site needs, the effective volume of the sedimentation tank is reduced. In actual production operations, sludge leakage and failure to reach the designed flow rate are prone to occur.

[0005] It was found during the actual project implementation that in the traditional process, the water distribution area is mainly the area connecting the reaction area and the sedimentation area. When designing the water distribution area, a special water distribution device is generally not set. When there is a special need, a baffle will be added as a water distribution device. However, this setting is prone to form dead corners in the water inlet pipe of the water distribution area and under the baffle, resulting in uneven water distribution, sludge accumulation at the water inlet end of the water distribution area, uneven water quality, etc., which affects the subsequent sedimentation and flocculation operation effect. In addition, sludge is easily attached to the inclined tube and the lower part of the inclined tube sedimentation tank, and dredging treatment is required frequently during the implementation process. Therefore, it is urgent to design a water distribution device and an inclined tube sedimentation tank to solve the above technical problems. Utility Model Content

They are used to explain the present disclosure together with the following detailed description, but do not constitute a limitation of the present disclosure. Example

[0036] A water distribution device is installed below the water inlet on the inner wall of a water treatment device. The water distribution device 4 includes a fixed rod 41 and a connecting rod 42. One end of the fixed rod 41 is fixed to the pool wall of the water distribution area 3, and the other end of the fixed rod 41 is connected to one end of the connecting rod 42. A sleeve 43 is sleeved on the connecting rod 42, and a plurality of elastic limit blocks 44 are provided on the connecting rod 42.

It has strong operability and is conducive to subsequent equipment maintenance.

[0044] Specifically, a water inlet pipe 32 is provided at the water inlet 31, and the water inlet pipe 32 is in an inverted "L" shape, and the outlet of the water inlet pipe 32 is aligned with the water distribution device 4. The horizontal kinetic energy of the sewage is eliminated through the pipe wall, ensuring that the sewage is diverted by the water distribution device 4.

[0045] Specifically, the water distribution device 4 is provided with at least two layers, and the lower water distribution device 4 is aligned with the end of the water distribution plate 452 of the upper water distribution device 4 away from the connecting rod 42 to achieve multi-layer diversion.

[0046] Specifically, the sludge area 2 is provided with a scraper device 21, and the sludge area 2 is provided with a sludge discharge port.

[0048] Working process: sewage enters the water distribution area 3 through the water inlet 31 and the water inlet pipe 32, flows to the water distribution device 4, and after being evenly distributed by the water distribution device 4, flows into the sedimentation area 1. In the sedimentation area 1, the sewage is effectively separated by the inclined pipe 11. After the sludge is separated, it settles to the bottom of the sludge area 2. The sludge is sent to the sludge discharge port for discharge through the sludge scraper device 21, and the supernatant flows from the first water outlet 12 to the next-level treatment equipment.
