Description

Energy-saving fire dispenser

technical field

The utility model belongs to a fire distribution device for kitchen gas or liquid fuel stoves in the catering industry and a related similar fire distribution device for stove head heating.

Background technique

The combustion mode of existing burner head is: gaseous fuel directly enters burner head or distributing device, and gaseous fuel is to exit from the vent hole around the distributing device; burning. The disadvantages are: the mixture of fuel and blast air is poor, and the combustion is not thorough enough; when the blast volume is constant, the fire will be blown out when it is adjusted to a small fire. And for the liquid fuel, because the area of the fire divider is large, the temperature of the gasification place of the liquid fuel is low, causing the gasification of the liquid fuel to be incomplete, insufficient combustion, and the stock of the liquid fuel at the burner is also larger, wasting fuel.

Contents of the invention

The technical problem to be solved by the utility model is to provide an energy-saving fire distributor, which can fully burn the fuel, and can keep the tiny fire from being blown out under the condition of constant blast volume.

The utility model energy-saving fire distribution device includes a cover body, which is characterized in that the cover body is divided into an upper gasification pressurized chamber and a lower micro-fire combustion fire distribution chamber by a bottom cover in the cover body, and the bottom cover is provided with an air outlet. The fuel conduit is connected with the bottom cover and communicated with the gasification pressurized chamber.

The wall of the low flame combustion fire distribution chamber is preferably provided with fire distribution grooves at intervals.

The utility model utilizes the characteristic that the upper 1/2 place of the fire distributor has the highest temperature when the burner burns, and divides the fire distributor into an upper gasification pressurized chamber and a low-flame combustion fire distribution chamber at the lower end of the bottom cover through the bottom cover. Use the fuel conduit to guide the fuel into the gasification and pressurization chamber first. Due to the high temperature of the gasification and pressurization chamber: the gaseous fuel will be heated by the high temperature of the gasification and pressurization chamber, and the volume of the fuel gas will expand instantly. Pressurized ejection; for liquid fuel, the liquid fuel will be vaporized and pressurized instantly due to the high temperature heating of the vaporization pressurized chamber, and then pressurized and ejected from the air outlet hole on the bottom cover. After the fuel is pressurized and ejected from the air outlet of the bottom cover, it is fully mixed with the blast air in the furnace, and ignited and burned at the low-flame combustion fire distribution chamber. The fire power is evenly distributed to the furnace for heating through the fire distribution groove on the fire distribution chamber of the micro-flame combustion. And under the condition of constant blast volume, it can keep the tiny fire from being blown out.

The lower port of the fuel conduit is connected with the burner fuel outlet or the fuel outlet of the diversion connector added by the energy-saving fire dispenser. The flow guiding connector is a component connected with the energy-saving fire distributor of the present invention, which is provided for the burner with side outlet fuel. There is a fuel outlet at the upper end of the diversion connector, which is used to connect with the fuel conduit on the bottom cover of the energy-saving fire distributor; there is a diversion pipe (a threaded telescopic conduit can be used) on the side of the diversion connector, which is connected to the fuel conduit at the upper end of the connector. The export is connected. The inlet of the draft pipe is connected with the fuel outlet on the side of the burner, and the fuel is diverted to the center of the burner and then enters the energy-saving fire distributor.

The outer wall at the top of the cover preferably extends upwards to form an outer cavity. The height of the outer cavity is adapted to the stove head, which stabilizes the burning direction of the firepower and concentrates the combustion; quickly transmits the heat to the outer wall of the gasification pressurized chamber to ensure the temperature in the gasification pressurized chamber.

The advantages of the energy-saving fire divider are: the fuel gasifies quickly, mixes well with the blast air in the furnace, the fuel burns fully, and can keep the tiny fire from being blown out when the blast volume remains unchanged. And for the liquid fuel stove, reduce the stock of liquid fuel in the burner, save fuel.

Experiments have shown that: with an ordinary firearm, an oil stove burns for one hour, burns six pots of water about 100 kg, and uses 2.8 kg of diesel oil; a gas stove burns for one hour, burns five pots of water for about 85 kg, and uses 3.2 kg of gas.

After using the energy-saving firearm of the utility model instead, under the same conditions, the oil stove burns for one hour, burns about 100 kilograms of six pots of water, and uses 2.4 kilograms of diesel oil; gas.

Detailed ways

As shown in Fig. 1, in the cover body 1 of the utility model, the bottom cover 3 (set at the 1/2 height of the cover inner cavity) divides the cover inner cavity into the upper gasification pressurized chamber 2 and the lower low-flame combustion distribution chamber 5. The bottom cover 3 is provided with a plurality of air outlet holes 4, the fuel conduit 7 is connected to the bottom cover 3 and communicated with the gasification pressurized chamber 2, and a plurality of fire distribution grooves are arranged at intervals on the wall of the micro-flame combustion distribution chamber 5 6. The top outer wall of the cover body extends upward for a section to form an outer cavity 10 .

The lower port of the fuel conduit 7 can be directly connected to the fuel outlet of the burner, and for the burner with fuel on the side, a diversion connector shown in Figure 2 is added to connect with the fuel outlet 8 of the diversion connector. The upper end of the guide connector is a fuel outlet 8 , and a guide pipe 9 is arranged on the side to communicate with the fuel outlet 8 . The inlet of the draft tube 9 is connected with the fuel outlet on the burner side.

The fuel conduit 7 guides the fuel into the gasification pressurization chamber 2 first, and the gaseous fuel will be heated by the high temperature of the gasification pressurization chamber, and the volume of the fuel gas will expand instantaneously, and then pressurized and sprayed out from the air outlet 4 on the bottom cover 3; The liquid fuel will be vaporized and pressurized instantly due to the high temperature heating of the gasification pressurization chamber 2, and then pressurized and ejected from the air outlet 4 on the bottom cover. After the fuel is pressurized and ejected from the air outlet hole 4 of the bottom cover, it is fully mixed with the blast air inside the furnace, and is ignited and burned at the low-flame combustion distribution fire chamber 5. The fire power is evenly distributed to the furnace for heating through the fire distribution groove 6 on the fire distribution chamber of the micro-flame combustion. Under the condition of constant blast volume, the tiny fire can be kept from being blown out.

The height of the outer chamber 10 is adapted to the stove head, and when the firepower is ejected from the fire distribution tank, it plays the role of stabilizing the burning direction of the firepower and concentrating the combustion; the heat is quickly transferred to the outer wall of the gasification pressurization chamber to ensure that the gasification pressurization chamber temperature.
