[0002] The existing liquefied gas economizer is composed of a cast aluminum body, a liquid phase input port and a gas phase output port, a gasification tube connected to the liquid phase input port and the gas phase output port in the cast aluminum body, and an electric tube that wraps the gasification tube. The structure of the liquefied gas economizer with this structure is relatively complicated. The electric heating device adopts the heating cable installed in the cast aluminum body and wraps the gasification tube.
Once the liquefied gas economizer with this structure is damaged, it cannot be repaired, and the liquefied gas economizer can only be replaced as a whole, which greatly increases the user's use cost
Heating with heating belt, the heating effect is not ideal, which affects the gasification effect

Embodiment Construction
[0016] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0017] As shown in the figure, the liquefied gas economizer includes a cast aluminum body 4, and an insulation layer 2 is provided outside the cast aluminum body 4. The cast aluminum body 4 in this embodiment is a cuboid, but it can also be a cube, a square, or a square in practical applications. Cylinder or other shapes, the gasification tube 5 is embedded in the cast aluminum body 4, the gasification tube 5 in this embodiment has four helical sections 501 arranged in a row, and the helical sections can also be arranged in two rows and two rows in practical applications Arranged or arranged in a ring, and a heating rod slot 3 is provided at the central gap corresponding to each helical segment 501 on the cast aluminum body 4, and the inner bottom surface of the heating rod slot 3 is flush wi...

The invention discloses a liquefied gas economizer. The liquefied gas economizer comprises an aluminum casting main body; a gasifying pipe is arranged in the aluminum casting main body; and the head end and the tail end of the gasifying pipe are respectively a liquid-phase input port and a gas-phase output port, and are leaded out from the surface of the aluminum casting main body. The liquefied gas economizer is characterized in that the gasifying pipe is provided with at least two spiral sections; and heating rod slots are formed in the surface of the aluminum casting main body correspondingto center gaps of all spiral sections of the gasifying pipe. Electric heating rods are separated from the aluminum casting main body, and are positioned out of the aluminum casting main body to achieve disassembly, so that a heating device is convenient to use and maintain. The electric heating rods are used for heating, so that the heating efficiency is high; and a wrapping form by heat accompanying strips is changed to an insertion form of the electric heating rods, so that the number and the length of the spiral sections can be increased under the same volume, and the gasifying effect is improved; and the liquefied gas economizer is simple in structure, low in production cost and wide in application range, not only can meet the use of multiple stainless steel stoves in large foodservice industry, but also can meet synchronous use of multiple general cast iron stoves in medium and small foodservice industry.
Description
technical field [0001] The invention relates to a liquefied gas economizer, in particular to a multi-purpose liquefied gas economizer connected with gas and liquid dual-purpose valve steel cylinders and suitable for various gas stoves in various large, medium and small catering industries. Background technique [0002] The existing liquefied gas economizer is composed of a cast aluminum body, a liquid phase input port and a gas phase output port, a gasification tube connected to the liquid phase input port and the gas phase output port in the cast aluminum body, and an electric tube that wraps the gasification tube. The structure of the liquefied gas economizer of this structure is relatively complicated. The electric heating device adopts the heating cable installed in the cast aluminum body and wraps the gasification pipe. Once the electric heating device of the liquefied gas economizer of this structure is damaged, it cannot be repaired, and the liquefied gas economizer c...
