The utility model provides a kind of thin film evaporator flexible rotating scraper structure, not enough to solve above-mentioned prior art.
The scraper plate assembled by using high temperature resistant, anti-aging flexible material replaces the larger polytetrafluoroethylmaterial material of original hardness
Scraper plate, is conducive to avoiding being broken caused by scraper plate aging, comes off；Meanwhile, flexible scraper plate lighter weight does not easily cause spindle shaft
The skew of the heart, and save energy consumption.Further, be conducive to evaporating barrel in protection using the brush sample scraping article of bristles material
Meanwhile, reduce material film thickness, improve evaporation efficiency.
In order to realize the purpose of this utility model, intend using following technology：
A kind of thin film evaporator flexible rotating scraper structure, including main shaft, and rule are laid in outside the main shaft side wall
Some scraping blades and the scraper plate that is fixed at the scraping blade, it is characterised in that the scraper plate is made up of folded set of some flexible units,
The flexible unit is made up of two support bars clamping brush sample scraping article.
Further, the scraping blade includes two symmetrical scraping blade monomers, and the scraping blade monomer is L-shaped, two vertical plane inner clips
The fixed scraper plate is held, horizontal plane is fixed at the spindle outer wall by screw.
Further, the flexible unit is 2~4 groups.
Further, the support bar selects soft graphite material.
Further, the brush sample scraping article selects bristles.
Further, bag is provided with silica gel sealing layer on the outside of the brush sample scraping article.
The beneficial effects of the utility model are：
1st, the scraper plate that the utility model assembles by using high temperature resistant, anti-aging flexible material replaces original hardness
Larger polytetrafluoroethylmaterial material scraper plate, is conducive to avoiding being broken caused by scraper plate aging, comes off.
2nd, the flexible scraper plate that the utility model is used, lighter weight does not easily cause the skew of spindle axis, and is conducive to section
About energy consumption.
3rd, the utility model is conducive to while protection evaporation barrel, reducing material using the brush sample scraping article of bristles material
Film thickness, improves evaporation efficiency.
Brief description of the drawings
Fig. 1 shows that the utility model is cutd open to structural representation.

Embodiment
As depicted in figs. 1 and 2, a kind of thin film evaporator flexible rotating scraper structure, including main shaft 1, and rule are laid
In some scraping blades 2 outside the side wall of main shaft 1 and the scraper plate 3 being fixed at the scraping blade 2.The existing outer rim of the scraper plate 3 is often adopted
With dentalation, distance evaporation barrel is only 2mm；To ensure that the scraper plate 3 stable in high-speed rotation can scrape coat
Material, the scraping blade 2 is necessary for the scraper plate 3 and provides stable support, thus requires that the scraping blade 2 and the scraper plate 3 have and to the greatest extent may be used
Coincidence fixed-area more than energy, the distance for causing the existing scraping blade 2 and evaporation barrel is only that the dentalation of scraper plate 3 is high
Degree.It is existing studies have found that, the scraper plate 3 positioned at feed end is influenceed by larger mechanical strength and temperature change, and aging is most fast,
After breaking releasing, larger is influenceed on main shaft spin balancing.When main shaft rocks aggravation, scraping blade 2 described herein is in evaporative cylinder inwall
Contact, scraping.
The scraper plate 3 is made up of folded set of 2~4 groups of flexible units 4, and the flexible unit 4 clamps brush sample by two support bars 5 and scraped
Bar 6 is constituted.The support bar 5 selects soft graphite material, for strengthening blade coating of the brush sample scraping article 6 to steam barrel material
Intensity, while having the flexible and elasticity of increasing, when unfavorable factor causes it to contact with evaporation barrel, is not easy to cause barrel
Groove.The brush sample scraping article 6 selects bristles, high temperature resistant, anti-aging.Brush sample scraping article 6 described in wall scroll is not easy to evaporation barrel thing
Material is effectively scratched, but is combined after a plurality of brush sample scraping article 6, and fine and close bristles brush body fits in evaporation barrel and rotated
Sweep and scrape, can form thinner material bed, be conducive to improving evaporation efficiency.
The outside of brush sample scraping article 6 bag is provided with silica gel sealing layer 8.The silica gel sealing layer 8 is entered to the glued bar of bristles swipe
Row secondary seal, prevents the brush sample scraping article 6 to be scattered in knifing process in material.
Due to the flexible unit 4 use lightweight material, thus its rotation power consumption scraped significantly lower than existing polytetrafluoroethylene (PTFE)
Plate.
The scraping blade 2 includes two symmetrical scraping blade monomers 7, and the scraping blade monomer 7 is L-shaped, is clamped in two vertical planes 71
The fixed scraper plate 3, horizontal plane 72 is fixed at the outer wall of main shaft 1 by screw.By adding described 5 pairs of institutes of support bar
The supporting role of brush sample scraping article 6 is stated, it is described that the vertical plane 71 only needs the bottom for ensureing the scraper plate 3 to be stably fixed on
At main shaft 1, thus its height shortens than existing scraping blade highly significant, thus avoid its evaporation barrel is produced scrape and
Groove is formed, is conducive to extension device service life.
Illustrate that the utility model embodiment is as follows in conjunction with the embodiments：
As described in Figure 3, uniformly laid and be fixed on the outer wall of main shaft 1 using scraper plate 3 described in 6 groups in embodiment.It is described
Silica gel sealing layer 8 is wrapped in outside the brush sample scraping article 6, and it is described soft that the support bar 5 is clipped on the outer formation of the silica gel sealing layer 8
Property unit 4, the scraping blade 2 is clipped on outside the flexible unit 4 of closed assembly, and is fixed and is clamped by fastening structure.It is described
Brush sample scraping article 6 is in contact with evaporative cylinder inwall 9, the top of silica gel sealing layer 8 to the top of brush sample scraping article 6 distance for 5~
10mm, the top of support bar 5 to the top of silica gel sealing layer 8 distance is 2cm or so, the top of scraping blade 2 to the branch
The top of stay 5 distance at least 10cm.
Material is flowed into after the evaporative cylinder inwall 9, and the main shaft 1 drives the scraping blade 2 and the scraping article 3 to rotate, single group
The a plurality of brush sample scraping article 6 in the flexible unit 4 is under the support of the support bar 5 and the silica gel sealing layer 8, along institute
State evaporative cylinder inwall 9 and sweep and scrape material.Material under gravity, forms relatively thin coating materials layer along the evaporative cylinder inwall 9, with steaming
After vapour chuck 10 exchanges heat, the moisture evaporation in material, larger material was snapped down to receiving section along the evaporative cylinder inwall 9 and received the first time
Collection.
