Novel observable aerodynamic liquid backflow device

Technical Field

The utility model belongs to the technical field of sewage treatment device, concretely relates to novel observable aerodynamic liquid backward flow device.

Background

The reflux device (sludge reflux and aerobic pool mixed liquid reflux) applied to the small buried sewage treatment device at present can not be matched with a complete pump valve device like a large sewage treatment project, so that the reflux device which can replace the conventional reflux device with a water pump and can also pass through smaller energy consumption and lower equipment investment is required to be invented. In conclusion, I designed a novel observable aerodynamic liquid reflux device.

Disclosure of Invention

In order to solve the existing problem, the utility model provides a novel observable aerodynamic liquid backflow device.

The utility model discloses a realize through following technical scheme:

the utility model provides a novel observable aerodynamic liquid backward flow device, includes that fan, air distribution use expansion tank, air branch pipe, the exit end of fan is installed the expansion tank for the air distribution: the top of the expansion tank for air distribution is connected with a plurality of vertically arranged air branch pipes; the air branch pipes are respectively provided with an independent manual adjusting valve; the top ends of the plurality of air branch pipes form a pipeline through the merging head to be conveyed to the liquid pool and are connected to the side part of the liquid return pipe; and the other end of the liquid return pipe is connected with a water outlet open trough.

As a further optimization scheme of the utility model, the liquid return pipe is an inverted L-shaped structure; the lowest end of the liquid return pipe is connected with a conical head.

As a further optimization scheme of the present invention, the connection position of the air branch pipe and the liquid return pipe is close to the low end of the liquid return pipe, and the air branch pipe and the liquid return pipe are internally ventilated.

As a further optimization scheme of the utility model, the water outlet open trough adopts an open standard-size structural form, and the backflow flow is calculated by observing the flow velocity change in the water outlet open trough, so that the flow control can be realized, and the formula is as follows; q is V S, (Q is reflux flow, V is water flow velocity in the open groove, and S is water outlet section area of the open groove).

Compared with the prior art, the beneficial effects of the utility model are that: the novel sewage treatment device emphatically overcomes the defects that the conventional backflow device is high in energy consumption, large in installation space and incapable of visually observing backflow liquid, so that the small sewage treatment device can realize the backflow function same as that of a medium and large sewage treatment system, and the small sewage treatment device really achieves' the effect of keeping sparrows in small five internal organs; and the liquid reflux is realized on the premise of less investment and lower energy consumption; and the condition that the return water flow cannot be accurately measured in the conventional aerodynamic liquid reflux device is solved.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1-2, a novel observable aerodynamic liquid backflow device comprises a fan (1), an expansion tank (2) for air distribution and an air branch pipe (3), wherein the expansion tank (2) for air distribution is installed at the outlet end of the fan (1): the top of the expansion tank (2) for air distribution is connected with a plurality of vertically arranged air branch pipes (3); the air branch pipes (3) are respectively provided with an independent manual adjusting valve; the top ends of the air branch pipes (3) form a pipeline through a merging head to be conveyed to the liquid pool and are connected to the side part of the liquid return pipe (4); the other end of the liquid return pipe (4) is connected with a water outlet open trough (5); the liquid return pipe (4) is an inverted L-shaped structure; the lowest end of the liquid return pipe (4) is connected with a conical head; the connecting position of the air branch pipe (3) and the liquid return pipe (4) is close to the lower end of the liquid return pipe (4), and the air branch pipe is communicated with the interior of the liquid return pipe (4); the water outlet open trough (5) adopts a structural form of an open standard size, the reflux flow is calculated by observing the change of the flow velocity in the water outlet open trough (5), and the flow control can be realized; q is V S, (Q is reflux flow, V is water flow velocity in the open groove, and S is water outlet section area of the open groove).

The novel device in this embodiment, the novel device utilizes the principle of stripping and is optimally designed on the basis of the principle. Firstly, air is conveyed into the liquid return pipe through the air pipe, the air bubbles rise in water by virtue of buoyancy of the air bubbles, and the liquid above the bubbles is lifted together in the rising process of the bubbles, so that the aim of stripping is fulfilled.

However, the reflux realized by the stripping action often cannot accurately control the flow, so that aiming at the problem, a group of water outlet open grooves which can be conveniently observed and can be metered are matched at the water outlet end of the liquid reflux pipe, the water outlet open grooves adopt a structural form of an open standard size, the reflux flow is calculated by observing the flow speed change in the open grooves, and the flow control can be realized.

Note: q ═ V × S
