Embodiment Construction

[0012] As shown in accompanying drawing 1: ascending tube 6,15,17 is rigid straight tube, and bottom inlet (41) is trumpet shape, and top outlet (42) is mushroom shape, and the top cover 20 of mushroom outlet is fixed on by 4 fixing plates 18. On the bottom plate 19. The rising cylinder 17 is enclosed within the outside of the rising cylinder 15, and can slide up and down mutually. There is an upper guide sealing ring 30 on the top of the lower ascending cylinder 15, and a lower guiding sealing ring 29 is arranged on the bottom of the upper ascending cylinder 17. Two positioning latch boxes 16 are installed on the outer side of the lower end of the upper ascending cylinder 17, which are symmetrically arranged left and right. There are watertight bins 27 and 28 on the outside of the lower ascending cylinder 15, and the top of the upper ascending cylinder 17 is provided with a watertight chamber 32, which is used to provide buoyancy and keep the multifunctional aerator suspende...

Abstract

The multifunctional water pumping aerator as one efficient water mixing and aerating apparatus consists of central ascending tube, aerating chamber, air chamber and air releasing pipe. The central ascending tube is one circular tube capable of regulating length automatically based on water level, and its lower part constitutes aerating chamber and air chamber together with a large outside pipe. Via the perforated air releasing pipe installed in the inlet of the aerating chamber, compressed air is filled to the aerating chamber and filled air forms the large rising bubbles in the central ascending tube to drive the upward water flow in the central ascending tube. The multifunctional water pumping aerator is installed floated in water and anchored with bottom anchoring pier, and may be set in reservoir to inhibit the growth of algae, improve bottom ecological environment and inhibit the dissolving and diffusion of phosphorus, ammonia nitrogen, etc. in water.

Description

Technical field [0001] The invention relates to a hydraulic mixing aeration device, which is especially suitable for mixing reservoir water and lake water which are hydraulically stratified due to large water depth, and supplementing oxygen into the water. Background technique [0002] Reservoirs and lakes have large capacity, large water depth, and low fluidity, which bring some negative impacts. Due to the low mobility, many organic matter, nitrogen, phosphorus and other nutrients are deposited and accumulated in reservoirs and lakes, providing sufficient nutrition for algae and other phytoplankton. At the same time, due to the low mobility of water, the algae can stay in the surface water stably. , received sufficient light and reproduced in large numbers, which brought about the problem of eutrophication of the water body and affected the water quality. Due to the large water depth and low fluidity, it is easy to form water stratification phenomenon, that is, in summer,...
