Description

Sectional type scraper blade structure

Technical Field

The utility model relates to an evaporimeter field, in particular to sectional type scraper blade structure.

Background

The scraper type evaporator thins the material on the inner wall of the evaporator cylinder body through a scraper and efficiently and stably separates the organic solvent or the volatile solvent in a heat exchange mode.

The effect of scraper blade then lies in spreading out the material thin with the barrel inner wall, and the scraper blade structure on the current market is mainly rigid scraper blade as an organic whole, is fixed in on the rotor, but this kind of scheme, the interval of scraper blade and section of thick bamboo wall is fixed, and application scope limits, but the material receives many factors influence in the evaporation process, like residence time, self viscosity etc. thickness distribution is different.

And some raw materials are processed at the front end and then enter a vacuum heating environment, so that surface expansion is easy to occur, bubbles are formed, and the bubbles escape from a vacuum pipeline, so that waste is generated.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned problem, provide a sectional type scraper blade structure, adopt the scraper blade structure of sectional type, drunkenness and centrifugation are whipped from top to bottom, can let every section scraper blade according to material thickness, self-regulation and section of thick bamboo wall interval, under the effect of centrifugal force, thinner pressure to section of thick bamboo wall on, increase evaporation efficiency.

Furthermore, the foam is smashed to the defoamer, avoids because piling up of foam, leads to the material to descend slowly, avoids the raw materials extravagant simultaneously.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a sectional type scraper blade structure, includes central pivot and is fixed in the last chuck of central pivot upper and lower side and lower chuck, goes up and is equipped with at least three scraper blade fixed axles between chuck and the lower chuck, and scraper blade fixed axle coincide cover is equipped with a plurality of hollow cylinder scraper blades, and has the offset between cylinder scraper blade and the scraper blade fixed axle, and cylinder scraper blade border position protrusion is in last chuck and lower chuck.

Further, the distance between the cylindrical scraper at the topmost side and the upper chuck is 2-5 mm.

Furthermore, a defoamer is arranged on the upper side of the upper chuck of the central rotating shaft.

Furthermore, the defoamer is of a symmetrical paddle structure, and tapered through holes are uniformly distributed in the paddles.

Further, the number of the scraper fixing shafts is 4, and the upper chuck and the lower chuck are equally divided on the periphery.

To sum up, the utility model discloses possess following advantage:

the utility model discloses a scraper blade structure of sectional type, upper and lower drunkenness and centrifugal whipping can let every section scraper blade according to material thickness, self-regulation and section of thick bamboo wall interval, under the effect of centrifugal force, thinner pressure to section of thick bamboo wall on, increase evaporation efficiency.

Drawings

FIG. 1 is a schematic view of the present invention;

fig. 2 is an enlarged schematic view of part a.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

a segmented squeegee structure, as shown in FIGS. 1 and 2, includes a central shaft 1 and upper and

lower chucks

11 and 12 fixed to upper and lower sides of the central shaft 1.

The upper chuck 11 and the lower chuck 12 are hollow circular disc structures, at least three scraper fixing shafts 3 are arranged between the upper chuck 11 and the lower chuck 12, four scraper fixing shafts are arranged in the embodiment, and the upper chuck 11 and the lower chuck 12 are uniformly arranged on the periphery.

The scraper fixing shaft 3 is overlapped and sleeved with a plurality of hollow cylindrical scrapers 4, offset exists between the cylindrical scrapers 4 and the scraper fixing shaft 3, and meanwhile the distance between the cylindrical scraper 4 at the topmost side and the upper chuck 11 is 2-5mm, so that the scrapers can be self-adjusted in the working process.

And, the edge position of the cylindrical squeegee 4 protrudes from the upper chuck 11 and the lower chuck 12.

With continued reference to fig. 1 and fig. 2, the central spindle 1 is further provided with a defoamer 5 on the upper side of the upper chuck 11.

Specifically, the defoamer 5 is a symmetrical blade structure, and tapered through holes 51 are uniformly distributed on the blades.

The central rotating shaft rotates under the action of the motor, so that the cylindrical scraper can move up and down in a string manner and do centrifugal swinging.

The material gets into in the barrel of evaporimeter from between defoamer and the last chuck, evaporimeter during operation, because the effect of vacuum pump is in vacuum state in the barrel, and some raw materials, behind front end technology, after the heating of reentrant vacuum environment, surface tension expansion appears easily in the solvent class, and it is the same like blowing soap bubble, produces the foam.

The foam can carry some raw materials to escape from vacuum pipe, causes the waste, also can pile up because the foam in the barrel simultaneously, leads to the material to descend slower, and at this moment under the effect of defoamer, the foam can be scraped into in the bell mouth from the macropore side of bell mouth, extrudes from the aperture at the bottom of the toper again, and the foam is here circulated and is broken up, will break the whereabouts, and the in-process solvent class can be followed the vacuum because of the evaporation of being heated and is gone out, and liquid raw materials whereabouts.

In this scheme, diameter, length, the weight of cylinder scraper blade are confirmed according to specification, evaporation area, the barrel diameter of evaporimeter, and the evaporimeter of less specification, scraper blade size can be littleer, and the weight and the length of scraper blade are generally just decided according to the material, and the more viscous material, the scraper blade is longer, and weight is also heavier.

The weight of the blade is changed by changing the wall thickness and length of the blade, and the diameter of rotation of the blade shaft is changed by changing the wall thickness and length so as not to affect the efficiency of the blade.

Generally, the weight of the scraper is larger than that of the scraper, and the use effect is better.

Furthermore, the segmented flights have the advantage that the distance of the flights of each segment to the interior of the barrel is self-adjusting.

For example, the thickness of the material on the inner wall of a certain section of cylinder body is a little thicker due to the detention time and the viscosity, and the natural distance from the cylinder wall is a little larger when the scraper of the section works.

Similarly, if the material of section of thick bamboo wall other places is very thin, then because the effect of centrifugal force, the scraper blade will press to section of thick bamboo wall naturally, and the interval will dwindle by oneself, just so can let every section of scraper blade, according to the thickness of material, the self-regulation self and the distance of section of thick bamboo wall, the centrifugal force of material through the center pin rotation production as far as, and thinner pressure increases evaporation efficiency to section of thick bamboo wall.

To sum up, this scheme adopts the scraper blade structure of sectional type, and drunkenness and centrifugal whipping from top to bottom can let every section of scraper blade according to material thickness, self-regulation and section of thick bamboo wall interval, under the effect of centrifugal force, on thinner pressure section of thick bamboo wall, increase evaporation efficiency.
