Description

PAM pipeline normal water cleaning device

Technical Field

The utility model relates to a water cleaning device in a PAM pipeline.

Background

The efficient sedimentation tank is applied to a sewage advanced treatment process section and comprises a mixing sub-tank, a reaction sub-tank and a sedimentation sub-tank which are sequentially communicated. PAM is required to be added into the reaction sub-tank through a PAM adding pipeline for stirring the flocculating agent. Because of PAM throws the medicine mouth on the spray tube of throwing the pipeline and must adopt the small-bore, can form a large amount of debris on the pipeline and adhere to, if the irregular cleaning, it blocks up easily to add the medicine mouth, leads to adding medicine inhomogeneous, influences the flocculation and precipitation effect. PAM throws the spray tube of throwing the pipeline and is located the bottom in reaction branch pond, and the washing degree of difficulty is big, needs the interior evacuation of pond during the washing, influences production, and the operation is wasted time and energy, and is inefficient.

The utility model is further described with reference to the following figures.

Fig. 1 is a schematic diagram of the structure of the device.

In the figure: 1-reaction separation; 2-PAM spray pipe; 3-a medicament delivery conduit; 4-a dosing pump; 5-reclaimed water conveying pipe; 6-a flushing pipe; 7-valve A; 8-a transparent observation tube; 9-connecting pipe; 10-valve B; 11-a discharge pipe; 12-a discharge valve; 13-flocculation stirrer impeller.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in figure 1, a PAM pipeline normal water cleaning device, divide the PAM spray tube 2 in the pond 1 including being located the reaction, the interval is provided with a plurality of dosing mouths on the PAM spray tube, two way medicament pipeline 3 are connected at least to the PAM spray tube, every way medicament pipeline all connects dosing pump 4, medicament pipeline connects factory normal water conveyer pipe 5 through the flushing pipe 6 that has valve A7 all the way, two way medicament pipeline is linked together through the connecting pipe 9 that has valve B10, the flushing pipe, all install transparent observation tube 8 on the connecting pipe, transparent observation tube lower extreme sets up the delivery pipe 11 that has discharge valve 12.

In this embodiment, the transparent observation tube is a tapered plastic tube sleeve with a large top and a small bottom, and two ends of the tapered plastic tube sleeve are provided with connectors for connecting pipelines.

In this embodiment, the top of PAM spray tube all is equipped with flocculation mixer impeller 13, the PAM spray tube is the annular spray tube, and last adding medicine mouth of annular spray tube sets up. The annular spray pipe ensures that the path of the chemical adding port distributed in the water body is long, thereby being beneficial to the large-scale spraying of the chemical. The dosing port is used as a dosing point, and after the medicament is sprayed out, the medicament is directly stirred and mixed by the impeller of the flocculation stirring machine, so that flocculation reaction is fully generated. Annular spray tube pipe diameter is little, and water pressure is big, and the medicament sprays out under pressure, then stirs through flocculation mixer impeller, makes medicament and sewage intensive mixing reaction, is favorable to exerting the drug effect.

In this embodiment, in order to facilitate observation and control, the transparent observation tubes on the flushing pipe and the connecting pipe are arranged side by side, and the output port of the discharge pipe is located right above the reaction sub-tank.

During washing, the valve A and the valve B are opened, high-pressure reclaimed water enters the medicament conveying pipeline through the reclaimed water conveying pipe and enters the PAM spray pipe to carry out high-pressure circulating washing on the pipeline, the discharge valve is opened, the transparent observation barrel is observed at the same time, whether the reclaimed water in the barrel contains more sundries to be washed or not is observed, and when the observed sundries are less, the valve A and the discharge valve are closed after the reclaimed water is washed for a period of time.

If this patent discloses or refers to parts or structures that are fixedly connected to each other, the fixedly connected may be understood as: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In the description of this patent, it is to be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the patent, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the patent.
