Embodiment Construction

[0010] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0011] The present invention is mainly composed of bottom head 1, scraper frame 2, main shaft 3, movable scraper 4, jacket 5, evaporation section 6, distributor 7, separator 8, separation cylinder 9, motor and transmission system 10, etc.

[0012] When the present invention installs, install with 4 ear type bearings on the outer wall of the separating cylinder 9 and the frame.

[0013] The motor and transmission system 10 of the present invention adopts a 5.5KW 4-pole explosion-proof motor, which is equipped with a needle wheel reducer with a speed ratio of i11 and a mechanical seal of 205, and is connected and fixed on the LDJ65 frame. Through this mechanism, the main shaft 3 can obtain 130 rpm, that is, the linear velocity of the outer edge of the scraper is 4.08m / s. The separator 8 is placed in the vaporization chamber 9 (that is, the separation cy...

Abstract

The invention relates to a revolving scraper evaporator, particularly, a concentrate equipment for diluting materiel utilizing the mechanism of vacuum, heating and forced film-forming, and relates to the field of machining technology. The electric machine and the driving system jointly fix on the machine foundation, the separator mounted in the separating bowl fix on the principal axis where the distributor fixes, the movable scraper mounted on the rack of the scraper which mounts on the principal axis, and the side of the movable scraper is adjacent to the wall of the inner tube of vaporizing segment which mounts in the jacket. The invention has a big heat transfer coefficient, a short over current time and a big operating flexibility. The invention has a big intensity of evaporation, a low energy sources and operating cost, and a stable product quality. The invention adapts for evaporation, concentration, deoxygenation, and exsolution distilling purification for the heat-sensitive material, high viscosity material and easily crystallizing material with granules. The invention has an extensive use in the product of chemical engineering, petrochemical industry, medicine, agriculture chemicals, nature plant distill, biochemistry, daily chemical, food, fine chemical, and so on.

Description

technical field [0001] The invention relates to a rotary scraper evaporator, in particular to a device for concentrating diluted materials using vacuum, heating, and forced film-forming mechanisms, and belongs to the technical field of mechanical processing. Background technique [0002] In the prior art, single-effect, double-effect, triple-effect rising (falling) film evaporators are usually used as evaporators for falling film evaporation under vacuum conditions to achieve the purpose of concentrating diluted materials. But this kind of equipment has large volume, low efficiency and high investment. Taking the single-effect rising film evaporator as an example, the heater is of shell and tube type, and the evaporation intensity is low, and the evaporation intensity is 50-70kg / h.m 2 .h 2 o; Relatively speaking, the use of energy (steam) is wasteful, the operating cost is high, and the product quality is not stable enough. Contents of the invention [0003] The object ...
