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.

Referring to fig. 1-3, the present invention provides a technical solution: this flourishing appearance device of pitch film oven is through flourishing appearance dish 1 of the rotating-structure last gomphosis in pitch film oven box, through rotary rod 2 and the gomphosis of embedding hole 6 on flourishing appearance dish 1 and the bellied spacer block 4 of carousel 3 upper surface and the gomphosis of slot hole 7 of flourishing appearance dish 1 bottom, then drive flourishing appearance dish 1 uniform velocity rotation through rotating-structure, thereby can be at the pitch film oven box external well pitch sample of steadily fixing, the sample dish of drying by fire of avoiding being equipped with the pitch sample produces the slip at the in-process that carousel 3 starts and closes, the time of placing the pitch sample has greatly been practiced thrift simultaneously, the loss of box internal temperature when placing the pitch sample has been avoided, the accuracy of experimental data has been improved.

Specifically, 4 sample placing holes 5 are arranged, and the 4 sample placing holes 5 are structures formed by symmetrically digging out a geometric body formed by a large cylinder with the upper half part of 14mm in diameter and 5mm in height and a small cylinder with the lower half part of 8mm in diameter and 5mm in height from the sample containing disc 1, and are used for placing and fixing the sample drying disc, so that the sample drying disc is ensured not to slide in position; the embedding hole 6 is a hole hollowed in the sample containing disc 1, and the planar shape of the embedding hole is a U-shaped shape formed by a semicircle with the radius of 10mm and a rectangle with the length of 200mm and the width of 10mm, and is used for embedding the sample containing disc 1 into the rotating rod 2; the groove holes 7 are of cuboid structures with the bottoms of the sample containing discs 1 being recessed inwards by 10mm, the lengths of the groove holes being 140mm and the widths of the groove holes being 10mm, are distributed on the sample containing discs 1 in a T shape, and are used for being buckled with the separating blocks 4 on the rotary disc 3 and fixing the sample containing discs 1 on the rotary disc 3.
