Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in FIG. 1, a graphite blade evaporator comprises

The device comprises a cylinder body 10, wherein a circulating cavity 11 is formed in the side wall of the cylinder body 10; the circulating cavity 11 is arranged in the side wall of the cylinder 10, and a heat-conducting medium is introduced into the circulating cavity to heat the cylinder 10, so that the heating is more uniform.

The inner cavity 20 is located inside the barrel 10, the side wall of the inner cavity 20 is provided with a graphite layer, and the graphite layer on the side wall of the inner cavity 20 enables some corrosive flue gas to be isolated from a metal frame, so that the reactor is better protected.

The upper part of the cylinder body 10 is also provided with a feed inlet and a discharge outlet.

The inner cavity 20 is provided with

A stirring shaft 40, one end of which is connected with the driver 30, the other end is positioned at the lower fixing device 44 at the bottom of the inner cavity 20,

the stirring shaft 40 is driven to rotate by the driver 30.

Referring to fig. 2, one end of the stirring blade 41 is connected to the stirring shaft 40, and the other end is provided with a scraper 42;

and graphite layers are wrapped outside the scraping plate 42 and the stirring blade 41.

The stirring blades 41 are provided with a plurality of stirring blades 41, and the stirring blades 41 are arranged in layers; the squeegee 42 is vertically disposed.

The scraper 42 is a toothed scraper, and the toothed part is attached to the side wall of the inner cavity 20.

The scraper 42 rotates along with the stirring blade 41, and in the rotating process, the scraper 42 scrapes off substances on the side wall, so that the concentrated solution is ensured to be concentrated and dried rapidly.

The end parts of the stirring blades 41 on the same layer are respectively provided with two scraping plates 42, and the two scraping plates 42 are staggered at the same height at the scraping plate teeth.

For example, in fig. 2, the two stirring blades 41 on the upper layer are led to rotate, two scraping plates 42 are provided, the end surfaces of the two scraping plates 42 on the two sides are both in tooth shapes, and the tooth-shaped scraping parts reduce the influence of movement when scraping the wall, thereby preventing the material to be scraped from moving to the two sides; when the side wall hanging device is used, the two scraping plates 42 are staggered in the longitudinal direction, so that the scraping teeth on the two scraping plates 42 can fill up gaps mutually, and a better effect is achieved when the side wall is hung.
