Jet type hydraulic blender

Abstract

This invention relates to a jet type hydraulic blender. The jet type hydraulic blender comprises a blending body consisting of a hollow rotating shaft, a jet pipe and a nozzle, a main joint with a liquid inlet hole and a connecting hole which are communicated with each other. One end of the hollow rotating shaft is a perforated end, arranged in the connecting hole and communicated with the liquidinlet hole and the other end of the hollow rotating shaft is an unperforated end and is radially communicated with more than one jet pipe; a nozzle which forms an included angle of -45 to 45 degrees with a radial plane of the hollow rotating shaft and an included angle of 30 to 90 degrees with the jet pipe is fixed at the end of the jet pipe; and an axial position device is further arranged between the hollow rotating shaft and the main joint. When the hydraulic blender is used, the high-pressure liquid is ejected from the nozzle and the liquid is blended; the jet pipe is driven to rotate so as to blend the liquid by a reacting force generated by the ejected liquid; and the mechanical and hydraulic double blending function is realized on the premise of no increase of power equipment and energy consumption; the jet type hydraulic blender improves blending effect and efficiency, reduces energy consumption, has ingenious design, a simple structure and low cost, and is suitable to be usedas a blender in a methane-generating pit or a sewage treatment pond.

Description

technical field [0001] The invention relates to a mixer or an aerator, in particular to a jet type hydraulic mixer, which belongs to the technical field of mixers. Background technique [0002] In urban sewage treatment systems and biogas projects, it is generally necessary to use a mixer in an aeration tank or anaerobic tank to stir sewage containing suspended solids, thin mud, viscous liquid, etc., to strengthen liquid mixing and accelerate chemical reactions. There are three commonly used stirring methods: hydraulic stirring, pneumatic stirring and mechanical stirring. Hydraulic agitation is to set a number of nozzles in the reactor or reaction pool, and inject a certain pressure of liquid from the nozzles to drive the liquid in the reactor or reaction pool to move, so as to achieve the purpose of stirring. The position of hydraulic agitation is fixed, and the range of deflection Small, there is a stirring dead zone, but there is no phase boundary, which is beneficial to...
