Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a hydraulic mixing dosing mixer. Background Art

[0002] In the process of sewage treatment, it is often necessary to add coagulants, flocculants, disinfectants and other chemicals, and the sewage and chemicals need to be mixed quickly and evenly, so a dosing mixer is needed. The mixer described in the utility model specifically refers to a static pipeline mixer, which does not require external power, but through the three functions of cutting and diverting, reverse reflux, and vortex mixing, the added chemicals are quickly mixed with the water body.

[0003] Existing static pipeline mixers are equipped with fixed spoiler baffles to change the water flow in the pipeline to facilitate mixing of sewage and chemicals. However, after long-term use, impurities in the sewage will accumulate on the spoiler baffles and the inner wall of the pipeline at this point and are difficult to clean. Long-term accumulation can easily clog the pipeline. If corrosive impurities are encountered again, the spoiler baffles and pipelines will also be corroded, thereby affecting the normal use of the pipeline mixer. Utility Model Content

[0004] The utility model aims to provide a hydraulic mixing dosing mixer which is convenient to clean and has a longer service life.

[0005] The purpose of the utility model is achieved as follows: a hydraulic mixing dosing mixer comprises a pipeline, wherein the pipeline comprises a curved dosing section and a horizontal mixing section; a water inlet is provided at the upper end of the dosing section, and a mounting seat is provided at the outer end thereof; a water outlet is provided at the right end of the mixing section, a flushing groove distributed along its length is provided at the upper end of its outer periphery, and a sewage discharge groove distributed along its length is provided at the lower end of its outer periphery, a detachable flushing cover is provided on the flushing groove, and a detachable sewage discharge cover is provided on the sewage discharge groove; a dosing pipe, wherein the dosing pipe is arranged at the water inlet; a spoiler assembly, wherein the spoiler assembly is rotatably arranged in the mixing section, and is used to interfere with the water flow so as to fully mix the medicine; a driving mechanism, wherein the driving mechanism is arranged on the mounting seat and is transmission-connected to the spoiler assembly, and is used to drive the spoiler assembly to rotate.

[0006] Compared with the prior art, the beneficial effects of the utility model are: the mixer provided by the utility model is convenient for cleaning the mixing section, thereby reducing the failure rate and extending the overall service life of the mixer; specifically, a flushing trough and a sewage trough are opened at the mixing section of the pipeline to facilitate flushing and sewage discharge; in addition, a driving mechanism is provided to drive the spoiler component to rotate, thereby facilitating multi-directional flushing of the spoiler component; in addition, as the spoiler component rotates, the left-handed blades and the right-handed blades continuously scrape the inner wall of the mixing section of the pipeline; in addition, the spoiler component is also arranged to be detachable, thereby facilitating subsequent more thorough flushing and maintenance thereof.

[0007] Furthermore, the flow spoiler assembly includes a fixing frame, an intermediate shaft arranged on the central axis of the fixing frame and rotatably connected to the fixing frame at the right end, and a plurality of left-handed blades and right-handed blades sequentially spaced and distributed on the intermediate shaft. The flow spoiler assembly designed in this way has a better flow spoiler effect, so that the water flow and the medicine are mixed more fully.

[0008] As a preferred solution of the utility model, the dosing section is detachably mounted on the left side of the mixing section, a support frame is provided at the joint between the dosing section and the mixing section, a fixed seat is provided in the middle of the support frame, a rotatable rotating seat is provided on the fixed seat, and the left end of the intermediate shaft is detachably plugged into the rotating seat; the driving mechanism includes a transmission shaft rotatably plugged into the mounting seat and connected to the rotating seat at the right end, a worm gear reducer provided on the mounting seat and connected to the transmission shaft, and a handwheel provided at the input end of the worm gear reducer.
