Abstract

The utility model relates to a heating pot using steam as a heat source. The existing steam heating pot is composed of an upper cover (1), an outer cover (2), an inner liner (3), and a stirring device (4); the smooth inner liner has low heat transferring efficiency. The utility model is the improvement of the inner liner; the inner liner of a vertical part is changed into an accidented structure; the inner liner (3) with the structure adds heat transferring area, enhances pressure resistant intensity, can reduce the wall thickness of the inner liner (3), and thus, enhances heat efficiency, saves energy, and enhances work efficiency.

Description

A kind of Steam Heating still

It is the heating kettle of thermal source with steam that the utility model relates to a kind of.

Existing Steam Heating still all is thermal source with steam generally, and the inner bag of the heat energy of steam by the heating kettle chuck conducts to the heated medium in the still, to realize certain variation of medium, as chemical reaction, evaporation, crystallization or the like.Vertical heating kettle is a round barrel shape, and its primary structure is made up of agitating device, loam cake, staving, and staving comprises overcoat and inner bag, and the heating kettle that has then can not be provided with loam cake.Steam is entered in the interlayer of being made up of overcoat and inner bag by air intake, Low Temperature Steam is discharged by steam vent, in the steam flow process, the part heat is passed to medium in the heating kettle by ganoid inner bag, in heating process, medium in the continuous agitating heating still of stirring system makes its thermally equivalent, with sufficient chemical reaction or evaporation or crystallization or the like the purpose that reaches medium.As known from the above, the thermal efficiency of heating kettle is by the heat transfer area of inner bag and wall thickness decision.The shortcoming of this heating kettle is that level and smooth inner bag heat transfer efficiency is low, thereby causes the result that work efficiency is low, energy consumption is high.

The purpose of this utility model is to overcome the shortcoming of existing heating kettle, under the constancy of volume situation of heating kettle, increases the heat transfer area of inner bag, reaching the purpose that improves the inner bag heat transfer efficiency, so that improve work efficiency, cut down the consumption of energy.

Task of the present utility model is achieved in that under the constant situation of other structure of heating kettle, it is characterized in that the inner bag surface design of vertical part is become rough structure.

Advantage of the present utility model is that rough inner bag total surface area is higher than the total surface area of level and smooth inner bag far away, thereby has improved heat transfer area, and its direct effect is to improve work efficiency, reduces the steam consumption, has promptly reduced energy resource consumption.

Description of drawings: accompanying drawing is the utility model structure chart.

First embodiment: the Steam Heating still is formed by loam cake (1), agitating device (4) and by overcoat (2) and inner bag (3).Vertically the rough inner bag of part staving (3) is designed to wave structure, and the inner bag of bottom still is that level and smooth sphere is so that discharging smoothly.Because inner bag (3) is a corrugated, so its total surface area is far longer than the area of level and smooth inner bag, thereby has increased heat transfer area, improved the programming rate of medium in the heating kettle, thereby improved work efficiency, saved the energy.Because of the compression strength of corrugated inner bag (3) is higher than the compression strength of smooth surface inner bag, thus the inner bag wall thickness can design more thinner, thereby also can further improve the heat transfer efficiency of inner bag.

Second embodiment: based on first embodiment, vertically the rough inner bag of part (3) is designed to helical corrugation shape inner bag, this inner bag is except that the advantage with first embodiment, after entering in the interlayer that overcoat (2) and inner bag (3) constitute by air intake (5), advance again along the cycle of inner bag helical ripple direction and to discharge, make full use of the heat of steam, reduce the temperature of exhaust steam by exhaust hole (6), just can further cut down the consumption of energy for this reason, improve work efficiency.

Above embodiment describes concrete structure of the present utility model in detail, especially the concrete structure of inner bag (3).Hence one can see that, and the utility model has reached and given the phase purpose, has not both reduced the dischargeable capacity of Steam Heating still, increased the heat transfer area of inner bag (3) again, improved the heat transfer efficiency of inner bag (3), thereby improved work efficiency, saved the energy.
