Abstract

The utility model relates to a self-lubricating high speed magnetic stirring reactor. The magnetic steel arrangement on the inner and outer magnetic steel rotors adopts an axial sliding magnetic path. The upper and lower bearings of a stirring shaft adopt the sliding bearings made from wear-resistant and dry milling resistant materials. The position of the stirring shaft which is immersed into the material liquid is provided with a screw liquid raiser. The structure design can form the self-lubricating system of the bearing in the reactor to avoid the additional lubricant. The service life of the reactor is increased and the contamination to the medium in the reactor that is caused by adding the lubricant to the bearing is thoroughly avoided. In addition, the magnetic stirring reactor is provided with the instruments for monitoring rotating speed, pressure and temperature.

Description

Self-lubricating high speed magnetic stirring reactor

The utility model relates to a kind ofly can accelerate the medium reaction speed in industrial processes such as chemical industry, medicine, food, light industry, microorganism, strengthen mass transfer, heat-transfer effect, strengthen immixture and don't pollution medium, and be convenient to the self-lubricating magnetic agitation reactor of control automatically.

The magnetic agitation reactor efficiently solves the problem that medium leaks in the still chamber, but structurally exists following three problems:

1, interior magnet steel rotor and agitator thereof are supported by rolling bearing, and rolling bearing depends on lubricant, and bearing lubricant can not be changed or be added when reactor turns round, and can only add when assembling is dispatched from the factory or when overhaul of the equipments or change.Therefore, in producing operation process, because the synergy of factors such as the Korrosionsmedium in the kettle, microparticle, temperature alternating, bearing lubricant is easy to lose efficacy, thereby causes rolling bearing to damage, and influences the operate as normal of reactor.

2, still inner bearing lubricant will leak, decompose, evaporates under the factor effects such as operating temperature, liquid corrosion and vibration equipment in still, and lubricated evaporant or leakage can be polluted medium in the still.

3, reactor work does not have monitoring instrument, can't carry out automatic control or collection control operation.

The purpose of this utility model provides the axial push-and-pull magnetic circuit of a kind of employing, the self-lubricating that abrasion-resistant slide bearing and liquid lifter are formed, pollution-free, the magnetic agitation reactor that can monitor.

Solving scheme of the present utility model is: 1, the magnet steel cloth of internal-external magnetic steel rotor is listed in axial formation push-and-pull magnetic circuit, the axial force of the weight of magnet steel rotor and agitator thereof in the magnetic force that this push-and-pull magnetic circuit is produced overcomes.2, the swivel bearing with internal rotor and agitator thereof is designed to sliding bearing, and this sliding bearing adopts the material of high abrasion, anti-dry grinding to make.3, shaft immersion liquid position is designed to screw rod, and screw rod rotates and promotes liquid, makes the interior liquid of still rise to the sliding bearing position, reaches the lubricating bearings purpose.4, internal rotor rotating speed induction indicator, temperature monitor, pressure monitor device are installed.

Below in conjunction with accompanying drawing content of the present utility model is described in further detail:

Fig. 3: properties of journal bearing lubricated graph structure.

Fig. 4: screw rod liquid lifter structure diagram.

Self-lubricating magnetic agitation reactor is made up of motor (comprising reductor), magnetic coupling, agitator, monitoring instrument and kettle.Magnet steel rotor (10) outer steel rotor (2) passes to moment of torsion by separation sleeve (9) in, interior magnet steel rotor is suspended state under the effect of between centers push-and-pull magnetic circuit (Fig. 2), shaft (7) is bearing in sliding bearing (3,12) on, sliding bearing is mainly used in the radial constraint to shaft except that the axial thrust of bearing when starting.The other design of plain bearing housing has fluid passage (Fig. 3), can make liquid pass through lubricating bearings.Shaft immerses the design of liquid position screw rod (13) and screw rod cover (14), screw rod rotates with axle, liquid promotes thereupon, it is lubricated to flow to two bearings, final liquid flows out upper bearing (metal) (3), returns in the still chamber, and monitoring instrument is by pressure monitor device (4), temperature monitor (5), Speed Controller (11) is formed.

Self-lubricating magnetic agitation reactor with said structure, the weight and the axial force of magnet steel rotor and agitator in axially the magnetic force of pushing magnetic circuit generation can overcome, sliding bearing guarantees running accuracy and bears the dry friction of short time that screw rod liquid lifter can make still intracavity liquid rising lubricating bearings.Like this, fundamentally stopped the pollution of lubricant, and improved the service life of bearing medium.Therefore, this self-lubricating magnetic agitation reactor of being furnished with rotating speed, pressure, monitoring temperature instrument, can be used widely at industrial departments such as chemical industry, medicine, food, light industry, microorganisms, and be specially adapted to the production and the high production procedure of high rotating speed automaticity of high-purity medium.

Claims

1, the self-lubricating magnetic agitation reactor that has motor (comprising reductor), magnetic coupling, agitator, monitoring instrument and kettle, medium and still separate outward fully in the still, the weight of interior magnet steel rotor and agitator thereof is born by the magnetic force that axial push-and-pull magnetic circuit is produced, of the present utility model being characterised in that: the magnet steel Boulez of outer steel rotor and interior magnet steel rotor is axial push-and-pull magnetic circuit.
