Description
Technical Field
The utility model relates to an evaporimeter technical field, concretely relates to wiped film evaporator of area stirring.
Background
The wiped film evaporator is a novel high-efficiency evaporator which is forced to form a film by a rotary wiped film device, flows at a high speed, has high heat transfer efficiency and short residence time (about 10-50 seconds) and can perform falling film evaporation under a vacuum condition. When the device works, the mixed material radially enters the evaporator from the upper part of the heating area, is distributed on the heating wall surface of the evaporator through the distributing device, and is continuously and uniformly scraped into a liquid film with uniform thickness by the rotary film scraper on the heating surface and is spirally pushed downwards. In the process, the rotating film scraper ensures that a continuous and uniform liquid film generates high-speed turbulence and prevents the liquid film from coking and scaling on a heating surface, thereby improving the total transmission coefficient. The light components are evaporated to form steam flow which rises and reaches an external condenser directly connected with the evaporator through a steam-liquid separator; the heavy component is discharged from a cone material port at the bottom of the evaporator.
When the existing wiped film evaporator is used, the defect exists that after light components are evaporated and separated, the left heavy components are easy to scale, agglomerate and the like at the position of a discharge hole at the bottom of the evaporator, so that the discharge hole is blocked.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wiped film evaporator of area stirring, its problem of phenomenon such as heavy component appears scale deposit, caking, agglomeration easily in evaporator bottom discharge gate position when having solved current wiped film evaporator operation.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
the utility model provides a wiped film evaporator of area stirring, wiped film evaporator is including motor, pivot and scraper blade, the output of motor is connected and is driven the scraper blade through the pivot, the bottom of pivot extends wiped film evaporator's discharge gate position, and is connected with the stirring rake in the bottom of pivot, the stirring rake rotates with the scraper blade is synchronous.
The further improvement lies in that the stirring paddle consists of a first plane stirring paddle and a second plane stirring paddle, and the first plane stirring paddle and the second plane stirring paddle are arranged at different heights of the rotating shaft at intervals.
The further improvement lies in that the first plane stirring paddle and the second plane stirring paddle respectively comprise a plurality of stirring rods, and the outer end of each stirring rod is provided with a stirring sheet.
The further improvement is that the stirring sheet is obliquely arranged and is kept parallel to the inner wall of the wiped film evaporator.
The stirring rod and the stirring blade are both composed of an internal main body part and a scratch-resistant layer coated on the surface of the main body part, the main body part is made of alloy materials, and the scratch-resistant layer is a DLC coating.
The beneficial effects of the utility model reside in that: according to the wiped film evaporator, the stirring paddle linked with the evaporator motor is additionally arranged, so that high-speed stirring of heavy components is realized, the phenomena of scaling, caking and agglomeration of the heavy components are avoided, and the bridging phenomenon is avoided through disturbance, so that blanking is facilitated; in addition, the wiped film evaporator has the advantages of good structural durability, low cost and convenient realization.
