Diving mixer is mainly made up of motor, bearing block, bearing, mechanical sealing base, mechanical seal and impeller etc..Diving mixer prolonged application is in sewage, the impeller being arranged on armature spindle end rotates under the driving of motor, mechanical seal assembly is on mechanical sealing base, one group of fineness is made to be that the flat seal of minute surface is under the lubrication of liquid by the elastic reaction of spring, the most for the relative rotation, stoping liquid to enter motor cavity, the quality of its sealing property directly determines that can diving mixer normally use.
1. diving mixer prolonged application is in wastewater media, sanitary sewage and industrial wastewater complicated component, containing substantial amounts of float and the solid particle such as the grains of sand of various density and mud.Even across the process of front road technique, still some grains of sand and mud enter in subsequent technique.Diving apparatus is in operation; these solid particles can be deposited in the cavity at mechanical seal place, and on the one hand these solid particles can destroy the sealing surface of mechanical seal, makes liquid enter motor cavity; on the other hand making the heat radiation difficulty of sealing surface, causing diving mixer can not work until damaging.
2., owing to being constantly present certain gap between impeller and mechanical sealing base, the granule in sewage inevitably wants some to enter in the cavity at mechanical seal place, affects the safe handling of mechanical seal.
Summary of the invention
This utility model provides and uses efficient permanent magnet motor and containing the efficient permanent magnet diving mixer of pre-washing function, has energy-saving and cost-reducing and solid particle and can not be deposited in the cavity at mechanical seal place, it is ensured that effect of mechanical seal safe operation.
The technical solution of the utility model is as follows:
Efficient permanent magnet diving mixer containing pre-washing function, including impeller and mechanical sealing base, described impeller is assemblied on described mechanical sealing base formation cavity；Described mechanical sealing base is equipped with mechanical seal, in the cavity that described impeller and described mechanical sealing base are formed, is equipped with the miniature flushing wheel for rinsing described mechanical seal；Described miniature flushing wheel is assemblied on the wheel hub of described impeller, and along with described wheel rotation.
Described miniature flushing wheel is fixed on the wheel hub of described impeller by back-up ring.
Described miniature flushing wheel includes rinsing wheel body and diffuser；Described flushing wheel body is the curved surface frustum cone structure of circular platform type structure or side indent；Described diffuser is evenly distributed on the side of described flushing wheel body spirally.
The quantity of described diffuser is 2 ~ 5.
This utility model compared with prior art has the advantages that the efficient permanent magnet diving mixer that this utility model contains pre-washing function, can stop the solids particles precipitate in sewage in the cavity at mechanical seal place while energy-saving and cost-reducing, mechanical seal is rinsed by the minisize fluid that miniature flushing wheel produces, thus improves diving mixer service life.

Detailed description of the invention
Below in conjunction with the accompanying drawings the technical solution of the utility model is described in detail:
That the following description is substantially merely exemplary and be not intended to limit the disclosure, application or purposes.It should be appreciated that in whole accompanying drawings, corresponding reference represents identical or corresponding parts and feature.
As it is shown in figure 1, the efficient permanent magnet diving mixer containing pre-washing function, including impeller 1, miniature flushing wheel 2, back-up ring 3, mechanical seal 4, mechanical sealing base 5, bearing block 6, efficient permanent magnet submersible electric motor 7, sliding sleeve 8.Feature of the present utility model mainly diving mixer have employed efficient permanent magnet submersible electric motor, and impeller 1 is assemblied on mechanical sealing base 5, and impeller 1 is matched in clearance with mechanical sealing base 5, and forms the space of a constant volume between the two.
As in figure 2 it is shown, the efficient permanent magnet diving mixer containing pre-washing function comprises impeller 1, miniature flushing wheel 2, back-up ring 3 and mechanical sealing base 5.As it is shown on figure 3, described impeller 1 comprises blade 11 and wheel hub 12.As shown in Figure 4 and Figure 5, miniature flushing wheel 2 comprises flushing wheel body 21 and diffuser 22, rinses the curved surface frustum cone structure that wheel body 21 is circular platform type structure or side indent；Diffuser 22 is evenly distributed on the side rinsing wheel body 21 spirally, and in this utility model, the quantity of diffuser 22 is 2 ~ 5.Mechanical sealing base 5 comprises middle mechanical sealing static ring mounting groove 52 and the baffle 51 extended by mechanical sealing static ring mounting groove 52 to side.
Mechanical sealing base 5 is arranged on bearing block 6 by securing member, and the stationary ring of mechanical seal 4 is arranged in mechanical sealing base 5 stationary ring mounting groove 52.Miniature flushing wheel 2 is assemblied on impeller hub 12, and fixes with back-up ring 3.Miniature flushing wheel 2 is assemblied on the core of wheel hub 12 inner chamber of impeller 1, on the end of the armature spindle that impeller 1 assembles efficient permanent magnet submersible electric motor 7 by wheel hub 12, on the end of the armature spindle that the assembly of such impeller 1 and miniature flushing wheel 2 is just assemblied in efficient permanent magnet submersible electric motor 7.Taking turns 2 at impeller 1 and miniature flushing to rotate with the armature spindle of efficient permanent magnet submersible electric motor 7, mechanical sealing base 5 is in resting state, and impeller 1 and mechanical sealing base 5 form matched in clearance.
