Spiral-flow type water cap

Abstract

The invention provides a spiral-flow type water cap, which comprises a conical water cap body and a center water pipe. The spiral-flow type water cap is characterized in that a plurality of water outlets inclined in the vertical direction are formed in the conical water cap body; the center water pipe is arranged in the conical water cap body; a water passing opening is formed in the center water pipe; the plurality of water openings inclined in the vertical direction and the center water pipe form a water spiral flow passage. The conical water cap body and the center water pipe are integrally formed by plastics. The spiral-flow type water cap has the advantages that the structure is reasonable; the filtering efficiency is high; the reverse flushing effect is good; the service life is long, and the like.

Description

technical field [0001] The invention relates to the field of water treatment equipment, and is a swirling water cap, which is widely used in the treatment of water in petrochemical, metallurgy, electric power, papermaking, food, municipal and other industries. Background technique [0002] In petrochemical, metallurgy, electric power, papermaking, food, municipal and other industries, water consumption is large, and there are various types of water treatment equipment to meet different water quality requirements. As the main water passing device of the packing supporting layer of large-scale water treatment equipment, the water cap is usually installed and fixed on the supporting plate, which prevents the filter material from passing through and only allows water to pass through. It is suitable for equipment with various filter materials, such as ion exchangers with ion exchange numbers, filters with activated carbon, quick filters with quartz sand or multimedia, etc. [00...

AI Technical Summary

Problems solved by technology

[0004] The prior art water cap related to the present invention is a plastic water cap. The water outlets of this plastic water cap are all vertical straight ports. From the analysis of the water distribution effect, the disadvantages of the structure of the vertical straight ports are , when the water treatment equipment is running in the forward direction, the water flow from the vertical straight port is scattered, and the scattered water flow has poor compaction on the filter material of the filter equipment, and the density and depth of the filter material are insufficient, and the filtering effect Poor; when the water treatment equipment is in the backwashing state, water enters from the central water pipe of the water cap, and then exits through the vertical straight outlet, so that the backwashing water is not mixed enough, the agitation of the filter material is poor, the backwashing effect is poor, and the backwashing effect is poor. The force makes the nuts connecting the water cap relative to the supporting plate of the filter equipment loose or even fall off, which reduces the service life of the water cap
