Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described in detail:
The following description is substantially merely exemplary and is not intended to the restriction disclosure, application or purposes.It should be appreciated that in whole accompanying drawings, corresponding accompanying drawing labelling represents identical or corresponding parts and feature.
As it is shown in figure 1, the efficient permanent magnet diving mixer containing sand control and anti-winding function, including impeller 1, back-up ring 2, slider 3, mechanical seal 4, mechanical sealing base 5, bearing block 6, efficient permanent magnet submersible electric motor 7, bearing 8 and sliding sleeve 9.Feature of the present utility model is mainly diving mixer and have employed efficient permanent magnet submersible electric motor and mechanical seal has sand control and anti-winding function.
As it is shown on figure 3, mechanical sealing base 5 comprises second concave surface the 51, second convex surface 52, mechanical sealing static ring mounting groove 53.
As shown in Figure 4, slider 3 comprises baffle plate 31, filter screen the 32, first concave surface the 33, first convex surface 34.
As depicted in figs. 1 and 2, make-up machinery seal receptacle 5, mechanical seal 4, slider 3, back-up ring 2 and impeller 1 successively in the end of described motor shaft.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 53.
Described slider 3 and mechanical sealing base 5 coordinate for labyrinth gap, are provided with the first convex surface 34 of annular and the first concave surface 33 of annular bottom described slider 3；Described mechanical sealing base 5 is provided with second concave surface 51 and second convex surface 52 corresponding respectively with described first convex surface 34 and the first concave surface 33；First convex surface 34 of described slider 3 matches with the second concave surface 51 of described mechanical sealing base 5；First concave surface 33 of described slider 3 and the second convex surface 52 of described mechanical sealing base 5 match, and are matched in clearance radial and axial.Slider 3 is fixing with the motor shaft of efficient permanent magnet diving mixer to be connected, along with motor shaft rotates.When electric machine rotation, slider 3 can relatively rotate with mechanical sealing base 5.
The sand control of this utility model and anti-winding function are achieved in that and are inserted in pond guide rod by the efficient permanent magnet diving mixer after assembling by sliding sleeve 9 thereon, in place fixing after dropping to precalculated position.Starting blender makes impeller high speed rotating that sewage to be done work.When in the cavity that some sand grains and fiber substance enter between impeller 1 and mechanical sealing base 5, the protective cover of slider 3 and mechanical sealing base 5 composition is by isolated to sand grains and fiber substance and mechanical seal 4.On the one hand, the labyrinth seal structure that slider 3 and mechanical sealing base 5 are formed will stop sand grains and fiber substance to enter in the protective cover at mechanical seal place.On the other hand; for ensureing the circulation of the water in protective cover; reduce the use temperature of mechanical seal 4; filter screen 32 on slider 3 rotates with motor shaft, and under the influence of centrifugal force, the water in protective cover throws away from inside to outside; water inlet is supplemented again by labyrinth structure; form the water circulation not containing sand grains and fiber substance, effectively reduce the water temperature in protective cover and stop the entrance of twister, thus protecting mechanical seal use reliably and with long-term.
This utility model with the efficient permanent magnet diving mixer of sand control and anti-winding function, have energy-saving and cost-reducing while, the infringement to sealing surface of the sand grains in sewage can be prevented, it is to avoid fiber-like twister is wrapped on spring, it is ensured that mechanical seal was not lost efficacy.
