Technical field

The utility model relates to the metal cover for seat of a kind of ceramic marmite or metal pan (bucket), is specifically related to the energy-conservation metal cover for seat of a kind of ceramic marmite or metal pan (bucket).

Background technology

Present both at home and abroad traditional marmite or the metal pan (bucket) used of family expenses, commercialization, collective, basic structure difference is little, all is cylindrical pan (bucket), domestic regulations is littler, commercialization or collective with specification more greatly.General traditional marmite or metal pan (bucket) all will be placed on the cooking stove long period and decoct medicinal herbs to be apt to, or boil and cook rice over a slow fire, cook gruel or stewed stewing kindred, Baoshang or the like, because it is flat, heating surface area is little, the thermal-flame flue gas hot-fluid of cooking stove has only the part and the medicine of marmite or metal pan (bucket) lining heat exchange such as to be apt to, most of high-temperature flue gas hot-fluid is dispersed into the ambient atmosphere with short the overflowing from pot (bucket) bottom surface of heat-exchange time because of heat exchange area is little, its heat exchange efficiency is 40-45% only, belong to the highly energy-consuming maximum discharge, someone attempts to change into concavo-convex or increase a little fins flat, but the efficient increase rate is little.

Summary of the invention

The purpose of this utility model is at existing ceramic marmite or the low inferior situation of metal pan (bucket) heat exchange efficiency, using the aerothermodynamic theory combines with the innovation structure layout is ingenious, the energy-conservation metal cover for seat of the corresponding different size of a kind of ceramic marmite of the shroud different size of breaking through the traditional structure pattern or metal pan (bucket) is provided, solves the technical problem that traditional marmite or metal pan (bucket) are little with cooking stove thermal-flame flue gas hot-fluid heat exchange area and heat-exchange time is short by a relatively large margin (one times).

The utility model, comprise and be provided with the tubular body that forms matched in clearance with ceramic marmite or metal pan outer wall, described gap becomes the heat exchange exhaust passage, lower edge at the tubular body is provided with reducing diameter part, between the bottom of a pan of described reducing diameter part and ceramic marmite or metal pan, be provided with 3 or 4 bearings that are uniformly distributed along the circumference, in tubular upper part of body inboard, be provided with 3 or 4 the metal washers that are uniformly distributed along the circumference, metal washer and ceramic marmite or metal pan outer wall are loose fit.

The utility model, described tubular body comprise inner sleeve and the outer sleeve that is provided with the inner sleeve of not being with the insulation layer and band insulation layer, between inner sleeve and outer sleeve, are provided with the insulation layer.The insulation layer can or vacuumize or be formed by silicate thermal insulation paint and the setting of filled with polyurethane foam blowing agent by air.

The utility model, described inner sleeve and ceramic marmite or metal pan lateral wall be 3-8mm apart from a; The distance b in described inner sleeve and ceramic marmite or the metal pan the bottom of a pan is 8-20mm.

The utility model in the upper edge of described tubular body, is provided with a pair of carrying handle.

The utility model is provided with the annular row gas port or the radially uniform a plurality of steam vents of enclosed of open type in described tubular upper part of body.

The utility model has following advantage:

1, using the aerothermodynamic theory combines with the structure innovation layout is ingenious, make the energy-conservation metal cover for seat of corresponding different size of set shroud different size marmite or metal pan (bucket), increase heat exchange area effectively significantly (more than one times) and prolong heat-exchange time, make traditional marmite or metal pan (bucket) heat exchange efficiency bring up to 65% from 40-45%, adapted ZL200820028312.3 combustion gas injection collides burner mutually, its heat exchange efficiency can be brought up to 70-75%, fuel savings consumes 20-30%, the corresponding CO that reduces ₂Discharging 20-30%;

2, compact conformation, good looking appearance, working service is easy, and is safe and reliable durable, is applicable to various gas furnaces, oil and gas stove, blind coal furnace, honeycomb briquet stove.Be average family, collective unit, the desirable good merchantable brand of quick-meal stall, restaurant trade company, average family some months commonly used is saved the recoverable purchase price cost of burnup expense, and trade company, collective unit's two weeks commonly used are saved the recoverable purchase price cost of burnup expense;

3, market prediction, domestic have 50,000,000 potential user's demands at least, produces hundred million yuan of output value demands of 1-2 per year, gross profit 60% above returns of investment, corresponding flood tide fuel consumption and the flood tide CO of reducing ₂Discharging creates more jobs and social benefit such as tax revenue.
