Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] see figure 1 , the vaporization chamber 3 is provided with a nozzle 5, a pressure switch 4 is provided at the position corresponding to the nozzle 5 in the vaporization chamber 3, a liquefied gas heating device 6 is provided at the bottom of the vaporization chamber 3, and a vertical wheel feeder is provided in the vaporization chamber 3. The ice device 1 is provided with a one-way feeding valve 2 on the vertical wheel ice delivery device 1 .

[0015] Referring to the accompanying drawings, the vertical wheel ice delivery device 1 adds dry ice 7 into the vaporization chamber 3, and the liquefied gas heating device 6 heats the dry ice 7. The dry ice 7 is vaporized after heating, and its volume expands 700-800 times after vaporization. A very high pressure is generated in the vaporization chamber 3, and when the pressure reaches a certain...

Abstract

The invention discloses a cold propeller, wherein, a vaporization room (3) is provided with a jet tube (5); a pressure switch (4) is arranged in the vaporization room (3) corresponding to the jet tube (5); a heating device and a feeder (1) for feeding solid material are arranged in the vaporation room(3). The heating device is either a liquefied gas heating device (6) or a diesel oil heating device. The feeder (1) for feeding solid material is provided with a one-way feeding valve (2). An impeller (8) is arranged on a main shaft (9) in the jet tube (5). The invention is a cold propeller with advantages of simple structure, easy manufacturing, reliable performance, environmental protection and low cost.

Description

technical field [0001] The invention relates to a propeller, in particular to a cold propeller. Background technique [0002] The jet engine currently used in some equipment or aircraft provides power. The jet engine has a turbine in the casing and has a very complicated structure. It uses liquid fuel such as gasoline, aviation kerosene, etc. to burn violently in the engine to generate high-temperature expansion gas. It is sprayed out from the nozzle at high speed to generate huge thrust, which makes the equipment run at high speed and the aircraft fly at high speed. But there is a shortcoming in this jet engine exactly that jet engine interior temperature is very high, very high to the material requirement of jet engine, has increased the cost of jet engine, and the fuel price that jet engine uses is expensive, and the cost of use is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cold thruster with sim...
