Self-cleaning type water tanks

Abstract

The invention discloses a self-purification water tank, wherein a tank body is arranged longitudinally; a settling area is under a water storage area; the water storage area and the settling zone are separated by a cone-shaped clapboard; the bottom of the settling zone is in an inverted cone shape; a certain gap is formed between the periphery edge of the cone-shaped clapboard and the inner wall of the tank body; the center of the bottom port of the settling zone is provided with a sewage cleaning opening; the water storage area is provided with a water outlet and inlet pipe, part of the water inlet and outlet pipe is arranged longitudinally and is in the center of the water storage area; the upper end of the water inlet and outlet pipe is open to communicate with a tap water pipe; the lower end of the water inlet and outlet pipe is provided with an opening on the vertical surface of the tank body on the lower part of the water storage area; and the part of the water inlet and outlet pipe arranged longitudinally is provided with a plurality of water inlet and outlet holes at intervals. The water storage area is often in a calm state and does not interfere the settling zone, and is provided with two conical surfaces so that settlings are gathered towards the settling zone and the sewage cleaning opening respectively and automatically; and the lower part of the gap (a first passage) is provided with a plurality of flow guide plates so that the settling zone generates rotary vortex automatically when the sewage is discharged, and water flows into the settling zone from a plurality of directions so that the sewage cleaning speed is improved and the cleaning effect is good, stable and reliable.

Description

technical field

[0001] The invention relates to a tap water tank. Background technique

[0002] At present, some water tanks are required for the domestic water supply of high-rise buildings, but the water tanks currently used need to be manually cleaned regularly, which is time-consuming and labor-intensive. Also someone has designed a kind of semi-artificial cleaning type water tank, and it is to install similar cleaning brush and so on device at the bottom of the water tank, realizes cleaning by manual rotation of cleaning brush, but this design is inconvenient to use, because long-term use cleaning brush itself also has pollution , and once the cleaning brush is damaged, there is no cleaning effect, and the work reliability is poor. Contents of the invention

[0003] In order to overcome the above defects, the present invention provides a self-cleaning water tank, which has reasonable design, convenient use, good cleaning effect, low cost and reliable operation. [0...
