Abstract

Disclosed is a remainder heaters for domestic LPG cylinder, which is composed of an electric heater, a bracket and a weight-measuring indicator installed between the electric heater and the bracket. The utility model can directly measure out whether the inner of the liquefied petroleum gas cylinder used having remainder, so as to prevent the danger occurring caused by the pressure limiting valve is blocked and mistaken heating the heavy cylinder still having combustible gas inside. The electric heater can heat the remainder in the cylinder to 36-40 DEG C to cause the remainder in the cylinder to be gasified and burnt fully. The utility model has the advantages of simple structure, low cost and convenient use, and is an energy-saving device which can cause the remainder in the liquefied petroleum gas cylinder to be gasified and burnt fully.

Description

Remainder heaters for domestic LPG cylinder

The utility model belongs to household liquified gas tank raffinate Electric heating appliance.

Household liquified gas tank is after having used 60～90 hours, just no longer gasification of raffinate in the jar at normal temperatures, also misfired, remain combustable liquid about 0.75～2.25Kg like this jar because of can not toppling over by gasification combustion, cause waste, but also befouling environment, for a jar interior raffinate can fully be burnt, commercially available have a kind of YQ-1 of board energetically type raffinate heater, though this heater can heat raffinate, whether it can not directly be measured in the liquefied gas tank is raffinate, and need to confirm with other method, use trouble, and the insulation resistance 〉=5M Ω of YQ-1 type raffinate heater, also big inadequately.

The purpose of this utility model is to provide a kind of meter weight indicators that is equipped with for the deficiency that overcomes prior art, can measure used liquifier jar and be light jar (residual liquid tank) still liquefied gas tank raffinate heater of heavy jar (still having inflammable gas), can prevent from fully will weigh jar and heat and cause danger because of limited valve blocks miss.

The purpose of this utility model can reach by following measure.

Household liquified gas tank raffinate heater is made up of electric heater, meter weight indicators and carriage, electric heater is made up of electrical heating elements, chassis and guard shield, electric heater is placed on the carriage, the meter weight indicators is arranged between carriage and electric heater, the meter weight indicators is made up of the heavy spring of meter, the heavy pointer of meter and meter recalibration plate, and heavy jar, light jar indication arranged on meter recalibration plate.

Advantage of the present utility model:

1, being added with the meter weight indicators can prevent to cause danger because of pressure-limit valve blocks miss will weigh jar to heat.

2, can heat continuously residual liquid tank, not be subjected to time restriction.

3, also can be placed on liquefied gas tank bottom in the use during without the raffinate heater, replace base to use, can prevent that the liquefied gas tank bottom from making moist gets rusty, and prolongs to use and receives a mandate.

4, the insulation resistance of electric heater of the present utility model 〉=500M Ω, safety and reliability in the use.

Accompanying drawing 1 is the utility model overall structure and user mode schematic representation;

Accompanying drawing 2 is meter weight indicators structural representations.

1-electrical heating elements, 2-chassis, 3-guard shield, 4-carriage, the heavy spring of 5-meter, the heavy pointer of 6-meter, 7-meter recalibration plate, 8-liquefied gas tank

Embodiment:

Electrical heating elements 1 places in the chassis 2, adds a cover the integral body that guard shield 3 constitutes electric heaters on the chassis 2, and chassis 2 and guard shield 3 are made by refractory material.Electric heater places on the carriage 4, between electric heater and carriage 4, be equipped with the meter weight indicators of forming by the heavy spring 5 of meter, the heavy pointer 6 of meter and meter recalibration plate 7, meter recalibration plate 7 is marked with heavy jar, light jar two kinds of scales, can connect power supply, the use of can lighting a fire after about 15 minutes after being confirmed to be residual liquid tank after measured.Electrical heating elements is selected nickel-chromium resistance wire for use, power consumption 100W, 160 ℃ of the highest heating temperatures, owing to added guard shield 3, can guarantee that the highest heating temperature in liquefied gas tank bottom is 42 ℃ (when ambient temperature is 18 ℃, used 24 hours continuously), be in liquefied gas tank and manufacture and allow in the standard within operating temperature-40～60 ℃ scope.

Claims

1, a kind of household liquified gas tank raffinate heater of forming by electric heater and carriage 4, it is characterized in that between electric heater and carriage 4, being equipped with the meter weight indicators, the meter weight indicators is by the heavy spring 5 of meter, count heavy pointer 6 and meter recalibration plate 7 is formed, heavy jar (also having inflammable gas), light jar (residual liquid tank) two kinds of scales are arranged on the meter recalibration plate 7.

2, household liquified gas tank raffinate heater according to claim 1 is characterized in that the chassis 2 of electric heater and guard shield 3 made by refractory material, and electrical heater element 1 places in the chassis 2, on add a cover guard shield 3.
