The temperature and humidity of environment reaches the confined space effect of constant temperature and humidity；Operating personnel need to hold special welding gun, by fluoroplastics welding rod
It is welded on slowly and equably between two blocks of fluoroplastics.Fluoroplastics welding procedure is very complicated, and the operating time is caused significantly to increase
It is long；To ensure welding quality, costly funds to build constant temperature and humidity confined space；It welds Work tool and welding material is equal
Sufficiently expensive, labour cost is higher；And fluoroplastics when high-temperature soldering will produce toxic gas, and extensive work can even be made
At environmental pollution.When being attached with tube sheet using other modes exchange heat pipe, if close using high pressure gas progress in tube sheet
Feng Shi needs to consider the problems of that connection structure faces tube sheet anti-corrosion, internal high-pressure gas leakproof and bonding strength.
Invention content
The utility model provides a kind of tube plate structure of teflon heat exchanger, ensures the sealing of tube sheet internal high pressure air curtain
Property and the bonding strength between tube sheet and heat exchanger tube.
In order to reach the purpose, the utility model adopts the following technical solution：
A kind of tube plate structure of teflon heat exchanger, it is characterised in that：Including upper perforated plate, lower perforated plate and it is clipped on described
Casing between tube sheet and the lower perforated plate, described sleeve pipe form high-pressure gas seal with the upper perforated plate and the lower perforated plate
Chamber, the upper perforated plate upper surface and the lower perforated plate lower surface are equipped with fluoroplastics liner plate, and the fluoroplastics liner plate is to the set
Pipe side turns down, and described sleeve pipe inner surface is provided with annular groove, and metal tube expansion is equipped in described sleeve pipe and is clipped in the gold
Belong to the fluoroplastics heat exchanger tube between tube expansion and described sleeve pipe.
As a preferred embodiment, the groove section is rectangle.
As a preferred embodiment, the liner plate and the metal tube expansion be to bending on the inside of the groove, the patch portion with
Contact setting in ground on the inside of the groove.
As a preferred embodiment, described sleeve pipe is provided at both ends with the step structure of indent, the upper perforated plate and the lower perforated plate
It is clamped respectively with the step structure at described sleeve pipe both ends.
As a preferred embodiment, described sleeve pipe both ends inner side edge is provided with fillet.
As a preferred embodiment, the fluoroplastics liner plate is divided into liner plate and lower liner plate, the upper liner plate and the lower liner plate
End contacts setting with ground on the inside of the annular groove.
As a preferred embodiment, fluoroplastics heat exchanger tube one end is flushed with the upper backing surface, metal tube expansion end
Portion turns down and covers the heat exchange end surfaces.
To sum up, compared with prior art, the utility model has the advantage of：Fluoroplastics liner plate and the step on metal sleeve
Structure jointly limits tube sheet, and after expanded joint processing, fluoroplastics liner plate end is fixed in metal sleeve inboard groove, connection
Intensity is high；After hot cigarette warp, metal sleeve and tube sheet expand to a certain degree, liquid to be heated are flowed through inside metal tube expansion, therefore
Degrees of expansion is smaller, and two-way interaction strengthens the tightness to fluoroplastics liner plate, has ensured that structure was using conscientiously
Stability in journey.
