Embodiment
The preferred embodiment of the present invention is illustrated below in conjunction with attached drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment：As shown in Figure 1, a kind of energy-efficient scraper film evaporator of the present invention, including driving motor 1,
Retarder 2, cylinder 3, gas-liquid separator 4, steam (vapor) outlet 5, material inlet 6, distributing device 7, evaporation cylinder 8, strut 9, shaft
10th, insulation jacket 11, scraper plate 12, pivoted frame 13, end socket 14 and material outlet 15,8 top of evaporation cylinder are connected with cylinder 3, and
Steam (vapor) outlet 5 is embedded with 3 side wall of cylinder, gas-liquid separator 4 is installed, and run through on gas-liquid separator 4 and set in cylinder 3
There is shaft 10, cylinder 3 is provided with distributing device 7 with 8 junction of evaporation cylinder, and 7 one end of distributing device is equipped with material inlet 6, steams
10 upper hinge of shaft in hair cylinder 8 is provided with some pivoted frames 13, and 13 end of pivoted frame is fixedly connected with scraper plate 12, pivoted frame 13 it
Between by strut 9 support connect, evaporation 8 outside tight of cylinder have one layer of heat preservation chuck 11.
Shaft 10 and the retarder 2 at the top of cylinder 3 are rotatablely connected, and 2 one end of retarder is equipped with driving motor 1, passes through
Retarder 2 adjusts 10 rotating speed of shaft.
Shaft 10 is connected through 8 inside of evaporation cylinder with the end socket 14 of its bottom, improves the stability of device entirety.
14 bottom of end socket is equipped with material outlet 15, and feed liquid is discharged by material outlet 15 after concentration.
Strut 9 is made of high intensity, corrosion resistant metal material, in the environment of high temperature and high humility, high intensity, corrosion resistant
The strut 9 of erosion can effectively improve the service life of device.
