The utility model content
The purpose of this utility model provides a kind ofly can improve production environment, reduces waste of heat, improves the novel energy-conserving steam shrinker of heat shrink quality and contractive effect.
For realizing that the technical scheme that the purpose of this utility model is taked is: a thermal circulation heat protection screen is set in the cavity of this machine pyrocondensation chamber, be furnished with two-layer steam jet up and down in the cover, the top of pyrocondensation chamber body is cone-shaped, pyramid tip is the collection steam ports, position, both sides, cone lower end is connected with gas and isolates baffle plate, and form the zone that exothermal gas flows through between the thermal circulation heat protection screen, and constitute the gas circulation channel thus.
Described steam jet is made up of the vertical steam jet pipe and the transverse jet steam pipe that are distributed in upper strata admission pipe, the lower floor's admission pipe around the thermal circulation heat protection screen and be connected symmetric arrangement on the admission pipe and have a jet apertures, wherein, upper and lower layer air inlet pipe is connected with steam conveying pipe respectively, is provided with at least more than 8 with the upper strata vertical steam jet pipe of admission pipe bonded assembly.
The novel energy-conserving steam shrinker of making according to such scheme, its reasonable in design, easy and simple to handle, owing in the pyrocondensation chamber, be provided with the thermal circulation heat protection screen, make thermal contraction space and outside production environment form two gradient temperature difference, the volume of actual contraction place (high-temperature zone) greatly reduces (be about original 1/4), and the temperature difference also reduces half, so energy-saving effect is fairly obvious.Especially when carrying out the thermal contraction of differing heights bottle, can adopt the top steam supply or the mode of steam supply simultaneously up and down according to actual needs respectively, thereby actv. has solved the present situation of the thermal contraction inequality that big bottle produces owing to the difference of heat supply temperature.This machine is under the operating mode of normal contraction effect, and steam pressure only needs 0.1Mp to get final product, because the machine internal gas pressure is lower, so the contraction situation is importing and exporting and can seeing very clearly, to the stable vital function that played of contraction quality; Secondly, outside shrinker, almost can't see the existence of steam fog, production environment is greatly improved, and alleviated the contradiction of producing the steam supply anxiety.Compared with prior art, these facility have energy-saving and cost-reducing, and heat shrink is even, thermal contraction is effective, characteristics such as finished product rate height, steady quality.
