Rotary type pulse water distributor with corrugated guide rail

Abstract

The invention relates to a rotary type pulse water distributor with a corrugated guide rail. According to the rotary type pulse water distributor, the bottom of a water distribution groove (7) is provided with a water inlet pipe (10) and water distribution pipes (9); valve supporting seats (14) with the same number as that of the water distribution pipes (9) are fixedly connected to the inner wall of the water distribution groove (7), and each valve supporting seat (14) is internally provided with a piston valve rod (8); the piston valve rods (8) are fixedly connected with a roller cross rod (15); the roller cross rod (15) is fixedly connected with a roller fixing framework (20), and a pair of rollers (19) are arranged in the roller fixing framework (20); the top end of the water distribution groove (7) is provided with a bracket (5), and a bearing block (3) is arranged on the bracket (5); a speed reducer (2) and a guide rail wheel (6) are connected into a whole through a transmissionshaft (1); and a raised corrugated guide rail on the side surface of the guide rail wheel (6) is clamped into the pair of rollers (19) to slide. The rotary type pulse water distributor has the advantages of uniform water distribution and switching, controllability, convenience for mounting and compact structure and can be widely applied to water distribution of sewage or water treatment systems.

Description

technical field [0001] The invention relates to a corrugated guide rail rotary pulse water distributor, which is applied to the water distribution of sewage and water supply treatment systems, and belongs to the technical field of water treatment. Background technique [0002] The water distribution of the sewage and water supply treatment system, especially the hydrolytic acidification tank and the clarification tank, as the biochemical pretreatment process and advanced treatment process pool commonly used in the treatment of high-concentration sewage in sewage treatment, are more and more widely used in sewage treatment. Its technological requirements are also getting higher and higher. The effect of the hydrolytic acidification tank or clarification tank is largely determined by the water distribution and mixing method in the tank. At present, pulse water distributors are mostly used, and most of them realize the treatment of sewage such as hydrolysis acidification tanks ...

AI Technical Summary

Problems solved by technology

Although the vacuum pulse water distributor can flexibly adjust the pulse and cycle, it needs to install vacuum equipment during the construction process, and it produces a lot of noise during operation.

The door-cut water distributor installs a ring-shaped door on the central water inlet pipe, opens and closes the door with a pulse valve, and realizes the pulse cycle by the water level rise and fall time, but the processing of the pulse valve is difficult, and mud accumulation will cause the pulser to fail.

The structure of the siphon pulse water distributor is simple, but its production cycle and flow rate are fixed, so when the water inflow or process conditions of the hydrolysis acidification tank or clarification tank changes, the pulse cycle and flow rate cannot be adjusted according to the change of process conditions , which affects the sewage treatment effect of sewage treatment tanks such as hydrolytic acidification tanks or clarification tanks

The electric valve type water distributor is flexible in control, but requires electrical program settings. In addition to the main valve, it also needs to be equipped with maintenance valves, multi-point multi-valve, valves are not easy to disassemble and assemble, and the supporting cost is high.
