Abstract
An internal circulation-type scarper film evaporator with a hollow spindle belongs to the field of chemical machinery equipment and is mainly applicable for such technical processes as concentration, evaporation, distillation and the like in industries of chemical engineering, food processing, pharmaceutical manufacturing, environmental protection, etc. The scarper film evaporator adopts the following method: a spindle of a conventional scraper film evaporator is replaced by the hollow spindle which can serve as a channel of internal circulation; a feed liquid accommodated at the bottom of the evaporator is injected into the hollow spindle, then led upwards to a liquid discharge hole at the upper end of the hollow spindle and discharged, and scattered on the surface wall of a heating chamber once again for cyclic evaporation after that. The steps are repeated several times until the feed liquid meets requirements, and finally the feed liquid is discharged.
Description
Technical field:
The circulation scraper film evaporator belongs to the chemical mechanical equipment field in a kind of hollow shaft, mainly be applicable in the industry such as chemical industry, food processing, pharmacy, environmental protection concentrate, technical process such as evaporation, distillation.
Background technology:
Scraper film evaporator is widely used in chemical industry, food processing, pharmacy, industrial circles such as environmental protection, be to utilize to rotate at a high speed liquid distribution is become homogeneous film and the evaporation of heating, thereby concentrate or distillating liquid, also can carry out deodorization, a kind of chemical mechanical equipment of deaeration, scraper film evaporator is mainly by rotating shaft, the feed liquid distribution plate, scraper plate, vaporization chamber and chuck heating clamber are formed, during work, feed liquid enters vaporization chamber from the top feed pipe, via the feed liquid distribution plate that rotates, throw to chuck heating clamber table wall, in feed liquid along the defluent while of heating clamber table wall, the scraper plate that is contained in the rotating shaft constantly rotates, feed liquid is spread to film along cylindric heating clamber table wall, make feed liquid be subjected to the heating of heating clamber table wall like this and evaporate, because the effect of feed liquid weight and scraper plate, the feed liquid film constantly is updated and is evaporated, at last, feed liquid adfluxion after the evaporation is in base of evaporator, become concentrate, the indirect steam that produces in concentrating can and flow to into gas-liquid separator with concentrate, or rises to the discharge of vaporization chamber top with countercurrent direction.This traditional method is very practical, but, because feed liquid is short in the heating clamber table wall time of staying, fast with the speed of gravity fall, evaporation process is uncontrollable, the feed liquid enrichment of flush distillation may be not enough, also need repeatedly to enter evaporimeter, perhaps also will strengthen evaporimeter, it is big to do equipment investment like this, complex process, and product quality is difficult to control.
Summary of the invention:
For improving existing scraper film evaporator efficient, reduce use cost, circulation scraper film evaporator in a kind of hollow spindle is now proposed, its main implementation method is such: the main shaft of scraper film evaporator that will be at present general makes hollow spindle into, because the main shaft of scraper film evaporator does not have other purposes except the transmission scraper plate at present, so the utility model is its effect expansion, with it as interior peripheral passage; Establish vaporization chamber in the chuck heating clamber, establish scraper plate in the vaporization chamber, scraper plate is equipped in hollow spindle.
Set end opening in the hollow spindle lower end near the base of evaporator place, outage is offered in the hollow spindle upper end, and hollow spindle links to each other with main reducing motor axle, establishes a screw by driven by servomotor at opening part.
Described screw is located at hollow spindle lower ending opening place, links to each other with servo motor shaft.
Like this, when the feed liquid evaporimeter of flowing through, when concentrating base of evaporator, the screw of described hollow spindle lower end rotates, and the feed liquid that will be collected in base of evaporator is injected hollow spindle, and on cause the hollow spindle upper end outage discharge, be dispensed onto heating clamber table wall once more, carry out circulating and evaporating, repeated multiple times just is discharged from up to satisfactory feed liquid like this.
Advantage of the present utility model is, has simplified the evaporation technology of scrapper thin film evaporator, has reduced equipment investment, and makes the evaporation technology process be easy to control.
Description of drawings:
Accompanying drawing 1 is the utility model section of structure, wherein:
(1) servomotor, (2) packing seal, (3) screw, (4) scraper plate, (5) hollow spindle, (6) vaporization chamber, (7) distributor, (8) main reducing motor, (9) concentrated solution outlet, (10) lower ending opening, (11) chuck heating clamber, (12) indirect steam outlet, (13) feed liquid inlet, (14) outage.
The specific embodiment:
As shown in Figure 1, feed liquid enters vaporization chamber (6) from feed liquid inlet (13), the distributor that is rotated (7) spills cloth to the inner surface wall of chuck heating clamber (11), spread to liquid film and constantly evaporation by scraper plate (4), scraper plate (4) is equipped on hollow spindle (5), hollow spindle (5) is driven by main reducing motor (8), when feed liquid concentrates base of evaporator, the screw (3) that hollow spindle lower ending opening (10) is located rotates, the feed liquid that is collected in base of evaporator is injected hollow spindle (5), and on cause hollow spindle (5) upper end outage (14) discharge, be dispensed onto the inner surface wall of chuck heating clamber (11) once more, carry out circulating and evaporating, like this repeated multiple times, be discharged from from concentrated solution outlet (9) up to satisfactory feed liquid, the indirect steam adverse current that evaporation produces is discharged from the indirect steam outlet (12) of evaporimeter upper end.
Claims (3)
1. the interior circulation scraper film evaporator of hollow shaft comprises: servomotor, screw, scraper plate, hollow spindle, vaporization chamber, distributor, main reducing motor, concentrated solution outlet, lower ending opening, chuck heating clamber, indirect steam outlet, the feed liquid inlet, outage is characterized in that: establish vaporization chamber in the chuck heating clamber, establish scraper plate in the vaporization chamber, scraper plate is equipped in hollow spindle, and hollow spindle lower ending opening place establishes screw.
2. according to the scraper film evaporator that circulates in the described a kind of hollow shaft of claim 1, it is characterized in that: described hollow spindle is set end opening, and outage is offered in the hollow spindle upper end, and hollow spindle links to each other with main reducing motor axle.
