Abstract
The utility model relates to a magnetic stirrer, in particular to a magnetic stirrer which is mounted at the bottom of a cylinder. The technical scheme includes that the magnetic stirrer comprises a driving device, an inner steel magnet with a stirring paddle, an isolation sleeve, a movable bearing and an outer steel magnet, an output shaft of the driving device is in linkage with the outer steel magnet, and the isolation sleeve is fixedly connected with a casing of the driving device. The magnetic stirrer is characterized in that a cylinder connection flange is sleeved on the isolation. The cylinder connection flange and the isolation sleeve are provided with lugs which are fixedly connected through bolts, and are hermetically matched. By the above technical scheme, for overcoming defects of the prior art, the magnetic stirrer which is convenient to mount and demount with the cylinder is provided.
Description
Technical field
The utility model relates to a kind of agitator, refers to especially be installed in the magnetic stirring apparatus under the cylinder body bottom.
Background technology
Magnetic stirring apparatus all is the agitator by magnetic drives, be totally-enclosed, without leak, free of contamination agitating mode; Because it is that to make it by magnetic drives be the non-contact type transmitting torque that does not have power transmission shaft, replaced the movable sealing of power transmission shaft with the static seal of separation sleeve isolation method, can thoroughly solve the insurmountable leakage problem of mechanical seal, this equipment is mainly used in the usefulness of the industry dissolvings such as pharmacy, food, mixing, batching; At present its problem of existing be and cylindrical shell between installation inconvenient, perhaps dismantle loaded down with trivial details.
Summary of the invention
For the deficiency that prior art exists, the utility model provide and cylindrical shell between install, the novel magnetic stirring apparatus of convenient disassembly.
For achieving the above object, the utility model adopts following technical scheme: a kind of magnetic stirring apparatus, include drive unit, interior magnet steel with paddle, separation sleeve, live bearing and outer steel, the wherein output shaft of drive unit and outer steel interlock, separation sleeve is fixedly connected with the housing of drive unit, it is characterized in that: be arranged with the cylindrical shell adpting flange on the described separation sleeve, be respectively arranged with lug on cylindrical shell adpting flange and the separation sleeve, be bolted to connection between the lug of cylindrical shell adpting flange and the lug on the separation sleeve, be sealed and matched between described cylindrical shell adpting flange and the separation sleeve.
By adopting such scheme, we just can be fixedly welded on the cylindrical shell adpting flange on the cylindrical shell, because cylindrical shell adpting flange and separation sleeve are sealedly and fixedly connected, get final product so only need to unclamp bolt in dismounting again, very convenient, and good sealing effect.
Of the present utility modelly further be set to: be provided with the shoulder rank on the outer peripheral face of described separation sleeve, be provided with on the described cylindrical shell adpting flange can with the boss of shoulder rank compression fit, be provided with sealing ring between described shoulder rank and the boss; Be provided with annular groove on the described shoulder terrace, described sealing ring is O-ring seals, and O-ring seals is arranged in the annular groove, and described separation sleeve is fixed on the housing of drive unit by connecting flange.
The purpose that the utility model further arranges is: make to be connected more rationally between cylindrical shell adpting flange and the separation sleeve, sealing effectiveness is better.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is that the utility model embodiment uses the status architecture schematic diagram;
Fig. 3 is the A section enlarged drawing among Fig. 1.
The specific embodiment
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of magnetic stirring apparatus, include drive unit 1, interior magnet steel 2 with paddle, separation sleeve 3, live bearing 4 and outer steel 5, the wherein output shaft of drive unit 1 and outer steel 5 interlocks, driving outer steel 5 rotates, separation sleeve 3 is fixedly connected with the housing of drive unit 1, present embodiment is that separation sleeve 3 is fixed on the housing of drive unit 1 by connecting flange 6, individual in the present embodiment, be arranged with cylindrical shell adpting flange 7 on the described separation sleeve 3, be respectively arranged with lug 71 on cylindrical shell adpting flange 7 and the separation sleeve 3,31, be bolted to connection between the lug 71 of cylindrical shell adpting flange 7 and the lug 31 on the separation sleeve 3, be sealed and matched between described cylindrical shell adpting flange 7 and the separation sleeve 3, adopt such scheme, we just can be welded on cylindrical shell adpting flange 7 fixing seals on the cylindrical shell, again owing to cylindrical shell adpting flange 7 and separation sleeve 3 are sealedly and fixedly connected, get final product so in dismounting, only need to unclamp bolt, very convenient, and good sealing effect.
In the utility model embodiment, be provided with shoulder rank 32 on the outer peripheral face of described separation sleeve 3, be provided with on the described cylindrical shell adpting flange 7 can with the boss 72 of shoulder rank 32 compression fit, be provided with sealing ring 8 between described shoulder rank 32 and the boss 71; In the present embodiment, for sealing ring 8 is more firm, be provided with annular groove 321 on 32 on the described shoulder rank, described sealing ring 8 is O-ring seals, and O-ring seals is arranged in the annular groove 321.
