The utility model relates to a rectifying still's of high-purity ethyl acetate further improves the part and lies in, and the terminal surface still is provided with decurrent extension plate under the kettle cover, the lateral wall of the extension plate laminating cauldron body.

The utility model relates to a rectifying still's of high-purity ethyl acetate further improves the part and lies in, and the annular groove is kept away from a lateral wall upper end slope of through-hole and is laid, and the annular groove on otic placode and the second otic placode offsets and is formed with and be annular closed angle concavity, the sealed inside wall that fills up is provided with the arch, protruding card is gone into the closed angle concavity.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses it has the connecting fastener cooperation to support the pole to support tight sealedly to be provided with the sealing pad, compares in directly establishing sealed effect of filling up better, sets up the extension plate simultaneously, reduces the possibility that gaseous entering otic placode and second otic placode binding face, has further strengthened sealed effect.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of a portion of FIG. 1;

in the figure: the reaction kettle comprises a kettle body 1, a kettle cover 2, lug plates 3, second lug plates 4, through holes 5, annular grooves 6, sealing gaskets 7, pressing plates 8, communicating holes 9, protruding parts 10, extension plates 11 and sharp-corner recesses 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the rectifying still for high-purity ethyl acetate comprises a still body 1 and a still cover 2, wherein an ear plate 3 facing to the periphery side is arranged on the upper end surface of the still body, a second ear plate 4 facing to the periphery side is also arranged on the lower end surface of the still cover, a plurality of through holes 5 are formed in the ear plates and the second ear plate, and connecting fasteners are arranged at the through holes and can be bolt and nut fasteners. Relative annular grooves 6 are formed in the ear plates and the second ear plate, sealing gaskets 7 are arranged in the annular grooves, communicating holes 9 are formed between the two annular grooves and the through holes, supporting rods are arranged in the communicating holes, and two ends of each supporting rod respectively support the connecting fastener and the sealing gasket. The bolt penetrates through the through hole and abuts against the abutting rod, so that the sealing gasket is further abutted against, and a good sealing effect is guaranteed.

Further, one side of the annular groove, which is close to the through hole, is also provided with an arc-shaped pressing and supporting plate 8, the pressing and supporting plate is provided with four groups of surrounding walls which are annularly arranged in the annular groove, the pressing and supporting plate is also provided with a protruding part 10, and the protruding part extends into a communication hole formed in the ear plate. Because the quantity of through-hole and connecting fastener is limited, set up and press the board and all press sealed periphery side to support, guarantee sealed effect.

Furthermore, the lower end face of the kettle cover is also provided with a downward extension plate 11, and the extension plate is attached to the side wall of the kettle body. Reduce the contact of gas and two otic placode contact surfaces, improve sealed effect.
