Abstract

The utility model relates to a residual gas promotion device for a liquefied gas bottle. At present, quite a part of residual gas can not be sufficiently combusted when people use liquid gas, the liquid gas is more difficult to be combusted up especially in winter or the north for the air temperature is low for cold, and the liquid gas only can be used by rocking, upending and scalding by hot water generally. Economization is not convenient, time and labor are consumed, and simultaneously the life time of the gas bottle is also influenced. A residual gas promotion sleeve device for the liquefied gas bottle is designed by the utility model, a movable gas promotion sleeve is installed on the liquefied gas bottle, the gas promotion sleeve is totally provided with three layers: an inner insulation layer, a middle electric heating layer and an external insulation layer, the gas promotion sleeve is made into the shape of an electric heating sleeve, and temperature is controlled by a timer. The utility model has the advantages of simple structure, convenient manufacture, energy saving and little investment.

Description

Gasification-promoting jacket for liquified-gas jar

The utility model relates to a kind of removing liquified petroleum gas cylinder residue residual gas, it is burnt fully reach energy-conservation new product, and liquified petroleum gas cylinder residual air is urged the air-casing device.

As everyone knows, along with the electrified continuous development of China, liquid gas uses more and more universal in the city, and liked by users, but China is the big country of 1,200,000,000 populations, scientific and technological level is also very backward, also supply falls short of demand in the use of liquid gas, do not reach the needs that satisfy the life of people's goods and materials far away, and this just requires us better to make full use of fuel, energy saving makes it fully burn and reach and make full use of it.At present, people find to have in the gas cylinder quite a few residual air to fail fully burning, especially winter or northern cold weather when using liquid gas, and more difficult to burn is intact.People often adopt and shake gas cylinder or scald or find time to liquefied gas station with hot water, find time each 1.5 yuan, so not only have been unfavorable for saving but also waste time and energy, and also influence the working life of gas cylinder.

The purpose of the utility model design is for overcoming above-mentioned deficiency, designing a kind of liquified petroleum gas cylinder residual air and urge the air-casing device from economy principle.

Below in conjunction with accompanying drawing this product is illustrated

Fig. 1 urges air-casing integral installation schematic representation for liquified petroleum gas cylinder residual air;

Fig. 2 urges the air-casing structural drawing for liquified petroleum gas cylinder residual air.

The utility model gasification-promoting jacket for liquified-gas jar as shown in Figure 1, it by liquefied gas bottle (1), urge air-casing (2), the bonding commissure of nylon (3), attaching plug (4), timer (5) to form. Be about to urge air-casing to be made into the movable sleeve of liquefied gas bottle size, as shown in Figure 2, set up the bonding commissure of nylon (3) on the cover limit of urging air-casing (2) cover is fixed on the gas cylinder. Control preheating time and temperature when loading onto power-line plug (4) power supply through timer (5), on timer box (5), also load onto strong and weak switch (6) and be used for The power of control temperature. After electric heating urged air-casing to be heated, the effect liquefied gas bottle made residue liquefied gas residue gasification in the liquefied gas bottle, fully burning. This liquefied gas bottle residual air urges air-casing (2) to be made up of interior insulation sleeve (7), nickel chromium triangle heat-conducting layer (8), external insulation layer (9); make the electric jacket shape; utilize nickel-chromium resistance wire to make conduction thermosphere (8); inside and outside insulating barrier (7), (9) adopt asbestos, artificial leather, plastics, coarse cloth, viscose glue to make seal protection layer, play anticreep safeguard protection effect.

This product designs according to pure third, butane temperature inversion, when 0 ℃ of temperature, is 4.8 atmospheric pressure, when temperature is 10 °, and 6.5 atmospheric pressure, in the time of 20 °, 8.5 atmospheric pressure in the time of 30 °, are 11 atmospheric pressure, are 14 atmospheric pressure in the time of 40 ℃. Be 0.17～0.3 atmospheric pressure when temperature 1 ℃ of time difference that raises, but the steel cylinder burst pressure generally has 80 atmospheric pressure, the butane saturated vapour pressure is 1.2,1.7,2.3,3.2,4.2 atmospheric pressure, when temperature increases 1 ℃, air pressure increases by 0.05～0.1, in the time of 41 ℃, also only have 4.3 atmospheric pressure, and the pressure-reducing valve inlet pressure is 0.2～10Kg/cm²So, as long as the external world heats 1 ℃ after the source of the gas of gas cylinder uses up, just can convert remaining liquid to gaseous state, also be safe and reliable simultaneously.

The utility model liquid gas residual air is urged the air-casing device, saves good energy-conserving effect, and is simple in structure, easy to make, little investment, and the benefit advantages of higher receives praises from customers.
