Abstract
The utility model discloses a kind of diving mixer with anti-winding function, this diving mixer anti-winding function structure is made up of impeller compacting ring, impeller, power transmission shaft, mechanical seal and mechanical sealing base.The cooperation of the sealing ring on impeller and mechanical sealing base forms labyrinth seal structure; radial and axial be matched in clearance simultaneously; make the twister outside main frame can not enter in the cavity at mechanical seal place, effective protection is formed to mechanical seal, ensure that diving mixer long-term safety is run.
Description
Technical field
The utility model belongs to environmental protection technical field, and what be specifically related to is the antiwind problem of mechanical seal in diving mixer.
Background technology
Diving mixer is widely used in sanitary sewage and technique for treating industrial wastewater, and be the capital equipment of sewage treatment process, diving mixer is primarily of compositions such as motor, bearing block, bearing, mechanical sealing base, mechanical seal and impellers.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, for the relative rotation closely, liquid is stoped to enter motor cavity side, prevent liquid from entering in motor cavity by the gap of armature spindle and the part such as mechanical sealing base and bearing block, the quality of its sealing property directly determines that can diving mixer normally use.
Diving mixer prolonged application is in wastewater media, and sanitary sewage and industrial wastewater complicated component, contain a large amount of various organic matters, inorganic solid, as suspension, precipitum, silt, the gravel of various density and shape.Diving apparatus is in operation, and the normal use impact of several situation on equipment is very large below.
1. some small-scale Sewage Disposal Craft, its technique is simple, front road sewage treatment process is less, the various solids entering diving mixer applying working condition are a lot, and the probability in the cavity making twister enter between mechanical sealing base and impeller increases greatly, and sealing surface can not tightly and uniformly be combined together, liquid is made to enter motor cavity side, or solid particle enters sealing surface damage sealing surface, makes sewage enter motor cavity equally, directly threatens mechanical seal safe operation.
Even if 2. large-scale water treatment technology front road sewage treatment process is perfect, but still the very little twister of some diameter or thickness enters in the cavity at mechanical seal place, forms harm equally to mechanical seal safe handling.
3., owing to always there is certain gap between impeller and seal receptacle, the twisters such as the fiber in sewage inevitably want some to enter in the cavity of mechanical seal, affect the safe handling of mechanical seal.
Summary of the invention
The utility model provides a kind of diving mixer with anti-winding function, twister can not be entered in the cavity at mechanical seal place, guarantee mechanical seal safe operation.
The matching design of feature of the present utility model mainly between impeller with mechanical sealing base becomes labyrinth seal structure, and twister cannot be entered in the cavity at mechanical seal place.Its main technical schemes: a kind of diving mixer with anti-winding function, comprises impeller and mechanical sealing base, sealing ring is contained in described impeller end, and between described sealing ring and described mechanical sealing base, matched in clearance forms labyrinth seal structure.
First seal groove of the first boss containing several annular on described sealing ring and annular, contains the second seal groove of the annular corresponding with the first boss on described sealing ring and the first seal groove and the second boss of annular at the end face of described mechanical sealing base; The first boss on described sealing ring inserts the second seal groove on described mechanical sealing base, and on described mechanical sealing base, the second boss inserts the first seal groove on described sealing ring, is matched in clearance radial and axial, and two mating parts form maze-type structure.Make the twister outside main frame can not enter in the cavity at mechanical seal place, effective protection is formed to mechanical seal.
The structure of described first boss and described second boss is rectangle or trapezoidal.
A kind of diving mixer with anti-winding function of the utility model, in the cavity that can prevent the twister in sewage from entering between mechanical sealing base and impeller, isolated and prevent from being wound around mechanical seal to it, thus ensure that diving mixer long-term safety uses, improve diving mixer service life.

Detailed description of the invention
The following description is only exemplary and be not to limit the disclosure, application or purposes in essence.Should be understood that, in whole accompanying drawing, corresponding Reference numeral represents identical or corresponding parts and feature.
As shown in Figure 1, with the diving mixer of anti-winding function.A kind of diving mixer with anti-winding function of the present utility model, comprises impeller compacting ring 1, impeller 2, power transmission shaft 3, mechanical seal 4, mechanical sealing base 5.Impeller 2 comprises wheel hub 21, blade 22, hemisphere 23, sealing ring 24, as shown in Figure 3.Wherein sealing ring 24 comprises the first boss 241 of annular and the first seal groove 242 of annular, as shown in Figure 5.Mechanical sealing base 5 comprises stationary ring installing hole 51, the second seal groove 52 of annular, the second boss 53 of annular, as shown in Figure 4.Described first seal groove 242 is annular groove with described second seal groove 52.
Mechanical sealing base 5 is arranged on main frame by securing member, and the stationary ring of mechanical seal 4 is arranged in mechanical sealing base 5 stationary ring installing hole 51, is assemblied in by impeller 2 on power transmission shaft 3, and wheel hub 21 is adjacent to the boss face of power transmission shaft 3, fixes impeller 2 with impeller compacting ring 1.The first boss 241 simultaneously on sealing ring 24 inserts the second seal groove 52 on described mechanical sealing base 5, and on described mechanical sealing base 5, the second boss 53 inserts the first seal groove 242 on described sealing ring 24, forms matched in clearance, as shown in Figure 6.Sealing ring 24 rotates with impeller 2, and mechanical sealing base 5, in inactive state, is matched in clearance radial and axial, and two mating parts form maze-type structure.Make the twister outside main frame can not enter in the cavity at mechanical seal place, effective protection is formed to mechanical seal, ensure that diving mixer long-term safety is run.
A kind of diving mixer with anti-winding function of the utility model, in the cavity that can prevent the twister in sewage from entering between mechanical sealing base and impeller, avoids twister and is wrapped on spring, ensures that mechanical seal was not lost efficacy.Thus ensure that diving mixer long-term safety uses, improve diving mixer service life.
