DETAILED DESCRIPTION

[0016] The accompanying drawings show a specific embodiment of the present utility model.

[0017] The distributor of the novel thin film evaporator of the utility model comprises an inner ring baffle 1, an outer ring distribution plate 2, a supporting bottom plate 3, a shaft sleeve 4, and a connecting plate 5; the supporting bottom plate is in a circular ring shape, the inner ring baffle is vertically welded to the upper part of the inner circle of the supporting bottom plate, the outer ring distribution plate is vertically welded to the upper part of the outer circle of the supporting bottom plate, the inner ring baffle 1, the outer ring distribution plate 2, and the supporting bottom plate 3 are combined to form a circular ring groove with an upper opening; a plurality of connecting strips 5 are connected and fixed between the inner circle of the supporting bottom plate and the outer wall of the shaft sleeve at the center.

[0018] In the distributor, the height of the inner circle baffle plate 1 is higher than that of the outer circle distribution plate 2, so as to prevent the liquid material from flowing down from the inner circle of the supporting bottom plate.

[0019] The outer ring distribution plate 2 of the distributor is a toothed plate, and its upper edge is a toothed structure, so that the liquid material flows out evenly from each groove of the toothed structure and flows onto the inner wall of the evaporator cylinder.

[0020] The thin film evaporator of the utility model is equipped with a distributor 17 .

[0021] The thin film evaporator comprises a cylinder 19, a mounting seat 8 is fixed on the top cover of the cylinder, a reduction motor 6 and a coupling 7 are mounted on the mounting seat; a rotating shaft 16 is mounted from top to bottom inside the cylinder, the upper end of the rotating shaft is connected to the coupling, and the lower end of the rotating shaft is mounted on an inner bottom bracket 11 at the bottom of the cylinder through a bearing; a distributor 17 is mounted in the middle and upper part of the rotating shaft, a scraper 20 is mounted on the lower part of the rotating shaft through a scraper connecting rod 15, and the scraper contacts the inner wall of the cylinder; a feed pipe 10 is mounted on the cylinder above the distributor.

[0022] In the thin film evaporator, a jacket 14 is installed at the lower part of the outer side of the cylinder, and the jacket is connected to the steam input pipe 13, the drain pipe, and the steam output pipe 21; an exhaust valve 18 is installed at the upper part of the cylinder.

[0023] The working process is as follows: the steam input pipe inputs steam into the jacket to heat the cylinder. The liquid material is input from the feed pipe and falls on the distributor. It flows out from the tooth grooves of the toothed plate and sticks to the inner wall of the cylinder. It is heated, evaporated and concentrated while flowing downward, and then scraped off by the scraper and falls to the bottom of the cylinder and discharged from the discharge port. The steam generated by the material heating gathers at the top of the cylinder and is discharged from the exhaust valve.
