Description
Technical Field
The invention relates to a processing method of a super-gravity purification bed, in particular to a method for processing a stator and a rotor of the super-gravity purification bed.
Background
The common supergravity purifying bed in the market at present has a double-layer stator and rotor structure and a three-layer stator and rotor structure, and is specifically calculated and selected according to the initial concentration of the ethanol to be purified and separated and the concentration of the ethanol required to be achieved after purification. In the production process, the stator and rotor processing deformation problem is faced no matter the double-layer stator and rotor structure or the three-layer stator and rotor structure. As shown in fig. 1, the stator comprises a stator disc and a stator retainer ring, a plurality of rings of annular grooves are formed in the stator disc, and the stator retainer ring is inserted into the annular grooves and welded and fixed with the stator disc. The rotor comprises a rotor disc and a rotor retainer ring, a plurality of rings of annular grooves are formed in the rotor disc, and the rotor retainer ring is inserted into the annular grooves and welded and fixed with the rotor disc.
Because the stator disc and the rotor disc are relatively thin (usually 5-7 mm), and are provided with a plurality of circles of annular grooves, a plurality of circles of stator check rings and rotor check rings are required to be welded, and the welding quantity is relatively large, so that the deformation of the stator disc and the rotor disc is difficult to control. The stator retaining ring and the rotor retaining ring are thinner, are only about 1mm, and only one end is a welding fixed structure when being welded with the stator disc and the rotor disc, the deformation of the stator retaining ring and the rotor retaining ring after welding is more difficult to control, and the formed stator retaining ring and rotor retaining ring are difficult to keep a regular cylindrical structure.
The stator is fixed on the super-gravity solvent purifying bed in the working process, the stator is a static part in the working process, the rotor is fixed on the transmission shaft and is a rotating part, and the rotor and the transmission shaft rotate together at high speed, and the rotating speed is about 600-1000 r/min. The materials separated and purified in the super-gravity solvent purification bed are generally a mixture of ethanol and water, the ethanol is an inflammable and explosive organic solvent, the design distance between the stator check ring and the rotor check ring at the outer ring of the super-gravity solvent purification bed is only 2-3mm, and if the deformation of the non-welded ends of the stator check ring and the rotor check ring is too large, friction can occur between the stator check ring and the rotor check ring and generate sparks when the rotor rotates at a high speed, so that safety accidents are caused.
At present, in the process of producing and processing stator and rotor, only a fixture can be used for fixing the stator disc and the rotor disc on a supporting frame in a spot welding manner, and the deformation of the stator disc and the rotor disc in the welding process is controlled. The deformation of the stator check ring and the rotor check ring can only be controlled by means of controlling the current during welding, intermittently staggering the azimuth welding and the like, and the effect of controlling the deformation by the means is not obvious. Especially for small-size supergravity solvent purification bed, stator retaining ring and rotor retaining ring design interval are less, can't satisfy the requirement.

The invention is described in further detail below with reference to the drawings and specific examples of the specification.
Fig. 2 to 4 show an embodiment of the present invention, as shown in fig. 1 and 2, a method for processing a super gravity purification bed stator and a rotor of the present embodiment, wherein the processing method of the stator includes:
s1, inserting an inner stator retainer ring 1 into an inner stator disc groove 41 and fully welding and fixing the inner stator retainer ring 1 on a stator disc 4;
s2, inserting the next stator retainer ring 1 into the adjacent stator disc grooves 41 of the fully welded stator retainer ring 1, positioning by spot welding, placing a limiting component 3 between the stator retainer ring 1 and the adjacent fully welded stator retainer ring 1 to limit welding deformation, and fully welding and fixing the stator retainer ring 1 on the stator disc 4;
s3, repeatedly executing the step S2 to fix all the stator retainer rings 1 on the stator disc 4 in a welding way;
the processing method of the rotor comprises the following steps:
s1, inserting an inner rotor retainer ring 2 into an inner rotor disc groove 51 and fully welding and fixing the inner rotor retainer ring on a rotor disc 5;
s2, inserting the next rotor retainer ring 2 into the adjacent rotor disc groove 51 of the fully welded rotor retainer ring 2, positioning by spot welding, then placing a limiting component 3 between the rotor retainer ring 2 and the adjacent fully welded rotor retainer ring 2 to limit welding deformation, and fully welding and fixing the rotor retainer ring 2 on the rotor disc 5;
and S3, repeatedly executing the step S2 to weld and fix all the rotor retainer rings 2 on the rotor disc 5.
According to the method for processing the stator and the rotor of the super-gravity purification bed, the inner stator check ring 1 (or the rotor check ring 2) is fully welded and fixed on the stator disc 4 (or the rotor disc 5), the diameter of the inner stator check ring 1 (or the rotor check ring 2) is minimum, and meanwhile, the gap between the inner stator check ring 1 (or the rotor check ring 2) and the adjacent stator check ring 1 (or the rotor check ring 2) is maximum, so that the method is suitable for being used as a limiting reference of the subsequent stator check ring 1 (or the rotor check ring 2). When each stator check ring 1 (or rotor check ring 2) outside is welded, the stator check ring 1 (or rotor check ring 2) is firstly subjected to spot welding positioning, then a limiting component 3 is placed between the stator check ring 1 (or rotor check ring 2) and the adjacent fully welded stator check ring 1 (or rotor check ring 2) to limit welding deformation, the deformation of the stator check ring 1 (or rotor check ring 2) during subsequent full welding can be effectively controlled, and experiments show that the deformation can be controlled between 0.3 and 0.5mm, meanwhile, due to the fact that the limiting component 3 is arranged, the intermittent welding time is greatly shortened, and the processing efficiency is improved.
Further, in the present embodiment, the stopper member 3 is placed at the end of the non-welded end of the stator ring 1 or the rotor ring 2 (see fig. 1, i.e., the lower end of the stator ring 1 or the upper end of the rotor ring 2). The farther the stator retainer ring 1 or the rotor retainer ring 2 is from the welding end, the larger the deformation amount during welding is, and the limiting component 3 is placed at the end part of the non-welding end of the stator retainer ring 1 or the rotor retainer ring 2, so that the welding deformation amount can be controlled more conveniently.
Further, in this embodiment, the limiting member 3 is cut by laser blanking of the plate material and burrs at the edges are removed. The limiting component 3 is obtained by cutting and removing the edge burrs through plate laser blanking, so that the machining precision of the limiting component 3 is guaranteed, and the welding deformation of the stator retainer ring 1 or the rotor retainer ring 2 is controlled.

Of course, in other embodiments, the limiting component 3 may also adopt a plurality of fan-shaped limiting blocks, and the plurality of fan-shaped limiting blocks are uniformly arranged along the circumferential direction, so that the effect of controlling welding deformation can be achieved, which is disadvantageous in that when the welding deformation is required to be placed or taken out, repeated operations are required, and therefore, the efficiency is lower than that of adopting a limiting ring plate.
Further, in this embodiment, the limiting member 3 is further provided with a handle 31. The inner side and the outer side of the limiting part are clung to the stator check ring 1 or the rotor check ring 2, so that the limiting part is not easy to take and place. The handle 31 is arranged, so that the stator retainer ring 1 or the rotor retainer ring 2 is conveniently placed in the machine, and meanwhile, the limiting component 3 is conveniently taken out after the welding of the stator retainer ring 1 or the rotor retainer ring 2 is finished, so that the recycling of the limiting component 3 is realized.

Of course, in other embodiments, the spacing component 3 is provided with a taking and placing hole, or the spacing component 3 is perforated, and the spacing component 3 is taken out or placed in through the perforation, so that the problem that the spacing component is not easy to take out or put in from between the adjacent stator retaining rings 1 or rotor retaining rings 2 can be solved.
While the invention has been described with reference to preferred embodiments, it is not intended to be limiting. Many possible variations and modifications of the disclosed technology can be made by anyone skilled in the art, or equivalent embodiments with equivalent variations can be made, without departing from the scope of the invention. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention shall fall within the scope of the technical solution of the present invention.
