At present, using evaporative cylinder on an evaporator all in straight tube shape, diameter keeps one i.e. up and down
Cause, feed liquid approximates whereabouts at the uniform velocity on the inwall of evaporative cylinder, due to feed liquid in evaporative cylinder dense
The time of contracting is affected by evaporative cylinder height, so under equal conditions, exists to extend feed liquid
The time (evaporating more solvent) concentrated in evaporative cylinder, it is necessary to increase the height of evaporative cylinder
Degree, it is relatively big that this results in whole scraper film evaporator volume, not readily transportable and use.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of high-efficient scraping
Plate-type thin film vaporizer, when it can extend feed liquid concentration in evaporative cylinder under equal height
Between, thus evaporate more solvent.
In order to realize above-mentioned target, this utility model adopts the following technical scheme that:
A kind of efficient scraper membrane evaporator, includes the most successively: evaporative cylinder (1),
Feeding cylinder (2), gas-liquid separation cylinder (3) and actuating device (4), wherein, evaporative cylinder (1)
Be internally provided with the scraper plate (5) driven by actuating device (4), outside is cased with heating jacket
(6), the top of heating jacket (6) is provided with steam inlet (61), bottom is provided with condensation
Water out (62), is provided with distributor (21) in feeding cylinder (2), it is characterised in that
Aforementioned evaporation cylinder (1) is made up of straight tube shape top (11) and conical lower (12),
The bottom of aforementioned conical lower (12) is provided with funnel shaped feed opening (13),
Aforementioned scraper plate (5) is plate-shaped, and inner side is provided with mounting seat (51), and passes through mounting seat
(51) being fixed in the rotary shaft of actuating device (4), outside has turning, turning and steaming
The changeover portion sending out cylinder (1) is contour, when actuating device (4) drives scraper plate (5) to rotate, scrapes
The inwall of evaporative cylinder (1) is close to by plate (5).
Aforesaid efficient scraper membrane evaporator, it is characterised in that the circular cone of evaporative cylinder (1)
Shape bottom is formed with some projections on (12).
Aforesaid efficient scraper membrane evaporator, it is characterised in that neighbouring is protruding wrong
Begin to rehearse cloth.
Aforesaid efficient scraper membrane evaporator, it is characterised in that aforementioned scraper plate (5) uses
Polytetrafluoro material or conductive carbon fibre material are made.
Of the present utility model have the beneficial effect that by changing the conventional straight tube shape of evaporative cylinder,
Its underpart is designed to cone, in the case of equal height, adds the road that feed liquid flows through
The length in footpath, and slow the speed that feed liquid flows downward, exist so effectively extending feed liquid
Concentration time in evaporative cylinder, such that it is able to evaporate more solvent, it is thus achieved that preferably concentrate
Effect, it is achieved efficient concentration.
Accompanying drawing explanation
Fig. 1 is the profile of a specific embodiment of membrane evaporator of the present utility model.
The implication of reference in figure: 1-evaporative cylinder, 2-feeding cylinder, 3-gas-liquid separation cylinder, 4-
Actuating device, 5-scraper plate, 6-heating jacket, 11-straight tube shape top, 12-conical lower,
13-feed opening, 21-distributor, 51-mounting seat, 61-steam inlet, 62-condensation-water drain.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model made concrete introduction.
With reference to Fig. 1, efficient scraper membrane evaporator of the present utility model wraps the most successively
Include: evaporative cylinder 1, feeding cylinder 2 (being inside provided with distributor 21), gas-liquid separation cylinder 3 and transmission
Device 4, wherein, evaporative cylinder 1 be internally provided with the scraper plate 5 driven by actuating device 4,
Outside is cased with heating jacket 6, and the top of heating jacket 6 is provided with steam inlet 61, bottom sets
It is equipped with condensation-water drain 62.
Evaporative cylinder 1 and the structure of scraper plate 5 are described in detail below.
Evaporative cylinder 1 is made up of straight tube shape top 11 and conical lower 12, and under cone
The bottom in portion 12 is provided with funnel shaped feed opening 13.
Conventional evaporative cylinder is straight tube shape, and upper and lower diameter is consistent all the time, and we are steamed by change
Send out the structure of cylinder, its underpart is designed to cone, so, in the situation of equal height
