Description

Liquefied petroleum gas energy-saving stove

technical field

The utility model relates to a liquefied gas energy-saving stove, which adopts the method of preheating the liquefied gas before igniting and burning, and has remarkable energy-saving effect, belonging to the technical field of kitchen utensils.

Background technique

The combustion method of old-fashioned stoves has always been to open the stove valve and ignite directly. The problem is that the natural gasification reaction of liquefied gas in the indoor liquefied gas tank is slow, and the firepower is obviously insufficient when using larger medium-pressure stoves in major hotels and restaurants. The reason is that there is always a certain amount of residual liquid in the liquefied gas tank that cannot be gasified and burned, causing a lot of waste. In addition, in the cold winter in the north, the liquefied gas tank cannot be used outdoors.

Contents of the invention

In order to solve the above problems, the purpose of this utility model is to provide an energy-saving stove for liquefied gas, which firstly heats the liquefied gas to a certain temperature and then ignites and burns, so that the combustion is more complete and completely solves the problem of slow natural gasification reaction at room temperature. For practical problems, one liquefied gas tank can use one or more large medium-pressure gas stoves at the same time. In addition, the residual liquid is basically burned to save energy and reduce environmental pollution. It can also be used outdoors in cold northern regions.

The technical solution adopted by the utility model to solve the technical problems is: the liquefied gas energy-saving stove, which is composed of a stove head, a stove valve, a connecting pipe head, a gasification ring pipe, an electric heating pipe, a preheater, and a preheater shell. , Circuit control part. An annular gasification ring pipe is fixed on the outside of the furnace head. The head end of the gasification ring pipe is connected to the gas inlet pipe through a connecting pipe head. A preheater is installed at the end of the gasification ring pipe. connection, the preheater is in the shape of a double-walled long cylinder, an electric heating tube is inserted into the inner cavity of the preheater, a preheater shell is arranged outside the preheater, and a circuit is installed on the outside between the preheater and the preheater shell Control section. The circuit control part is composed of a power switch, a manual anti-dry burner, a temperature controller, a red indicator light for heating, a green indicator light for heat preservation, electrical connection of resistance R ₁ and resistance R ₂ . The manual anti-dry burner and the temperature controller are fixed on the outer wall of the preheater, and the power switch, the red indicator light for heating, and the green indicator light for heat preservation are fixed on the shell of the preheater.

The beneficial effects of the utility model are: the device is simple in structure, economical and applicable, has the function of automatic control of preheating temperature and over-temperature protection, and only needs to be energized for heating at the beginning, and the waste heat is used to preheat the gas after ignition and combustion, which is suitable for use in hotels and restaurants .

Detailed ways

Please refer to Figure 1, Figure 2, and Figure 3, the liquefied gas energy-saving stove, which is controlled by the furnace head, stove valve, connecting pipe head, gasification ring pipe, electric heating pipe, preheater, preheater shell, and circuit Partial composition. An annular gasification ring pipe (4) is fixed on the outside of the furnace head (5), and the head end of the gasification ring pipe (4) is connected with the gas inlet pipe (1) through a connecting pipe head (3), and the gasification ring pipe (4) ) end is provided with a preheater (6), and the end of the preheater (6) is connected to the stove valve (2). ) is inserted with an electric heating tube (9), a preheater casing (7) is arranged outside the preheater, and a circuit control part is arranged between the preheater (6) and the preheater casing (7). The circuit control part is composed of a power switch (12), a manual anti-dry burner (10), a thermostat (11), a heating indicator red light (13), a heat preservation indicator green light (14), a resistor R ₁ (15), a resistor R ₂ (16) is electrically connected. Manual anti-dry burner (10) and thermostat (11) are fixed on the outer wall of preheater (6), and power switch (12), heating indication red light (13), heat preservation indication green light (14) are fixed on the preheater (6). on the heater shell (7).

Use process: Before using the gas stove, first turn on the power switch on the preheater, the red light of the heating indicator is on after the power is turned on, the thermostat is powered off after the heating reaches the specified temperature, the red light of the heating indicator is off, and the green light of the heat preservation indicator is on, at this time The angle valve of the liquefied gas tank can be opened, the gas is preheated when it passes through the preheater, and then the stove valve is opened to ignite and burn. Since the gasification ring pipe is arranged around the furnace head, the gasification ring pipe uses the waste heat to heat up the gas when the fire is used. The gas is preheated, and the power switch on the preheater is turned off at the same time after the stove ceases to fire. The function of the manual anti-dry burner is to cut off the power when the preheating temperature exceeds the specified temperature. After finding out the cause and troubleshooting, manually press the manual The button on the anti-boiler can be reset and works normally.
