Description

Technical Field

[0001] The utility model relates to the technical field of flame welding, in particular to a methanol microwave atomization device. Background Art

[0002] There are currently two main methods for welding copper wires and copper tubes: one is to use pure hydrogen and oxygen for welding. The hydrogen and oxygen flame produced by this method has the characteristics of high temperature and concentration, but the flame color is lighter and difficult to observe during operation; the other method is to let hydrogen and oxygen pass through alcohol liquid and mix with volatile alcohol molecules before burning and welding. This improves the problem of light flame color and excessive concentration, but the mixing amount of alcohol is not easy to control, resulting in large changes in flame temperature. Therefore, a new type of welding supporting equipment is urgently needed to solve this problem. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 The utility model provides a technical solution: a methanol microwave atomization device, comprising a tank body 1, a liquid adding port 2 is fixedly connected to the top of the tank body 1, the liquid adding port 2 is used to add methanol liquid, a sealing cover is provided on the liquid adding port 2 to ensure the airtightness of the device, and an air outlet 3 is provided below the liquid adding port 2 for outputting a methanol aerosol mixture mixed with compressed air.

[0019] A safety valve 4 is fixedly installed on the top of the tank body 1 away from the gas outlet 3. A pressure sensor 5 is arranged below the safety valve 4. When the internal pressure exceeds the set value, the safety valve 4 can automatically open to release the excess pressure to ensure the safety of the device. The pressure sensor 5 is used to monitor the pressure inside the tank body in real time.

[0020] A liquid observation window 10 is provided in the middle of one side of the tank body 1 away from the safety valve 4 , and an operator can observe the liquid level change of the methanol liquid in the tank body through the liquid observation window 10 .

[0021] A heating ring 7 is fixedly mounted at the bottom of the tank body 1 to heat the methanol liquid in the tank body so that it is easier to atomize.

[0022] A temperature sensor 6 is provided above the heating coil 7 for real-time monitoring of the temperature of the liquid in the tank to ensure that the atomization process is carried out at a suitable temperature.

[0023] A breathable steel 8 is installed at the center of the bottom of the inner cavity of the tank body 1. The breathable steel 8 is stainless steel breathable steel. Its function is to disperse the input compressed air into tiny bubbles, further promote the atomization of methanol liquid, and increase the pressure of the mixed gas.

[0024] Stainless steel is a special stainless steel material with good gas permeability and corrosion resistance. It is usually composed of a stainless steel matrix and a gas permeable medium, which can exchange gas through the pores or channels in the stainless steel matrix. This material has a wide range of application prospects in many industrial applications, especially in environments where gas circulation and corrosion resistance are required.

[0025] The main features of stainless steel breathable steel include:

[0026] 1. Breathability: The material has tiny pores or channels inside that allow gas to pass through.

[0027] 2. Corrosion resistance: It has excellent corrosion resistance and is suitable for various corrosive environments.

[0028] 3. Mechanical strength: It has sufficient mechanical strength to be used in high-pressure environments.

[0029] 4. High temperature resistance: can maintain stable performance under high temperature conditions.

[0030] Application areas include but are not limited to:

[0031] Chemical industry: used to manufacture corrosion-resistant and breathable equipment and pipelines.

[0032] Food Processing: Used in the manufacture of food processing equipment that requires gas exchange.

[0033] Pharmaceutical industry: used to manufacture medical equipment that requires gas circulation.

[0034] Environmental protection industry: used to manufacture sewage treatment and waste gas treatment equipment.

[0035] In short, stainless steel combines the corrosion resistance of stainless steel with the permeability of gas media, giving it unique advantages in many industrial applications.

[0036] A one-way valve 9 is fixedly installed at the bottom of the tank body 1. The one-way valve 9 is installed on the connecting pipe at the bottom of the tank body 1. Compressed air is input into the tank body 1 through the connecting pipe and turns into small bubbles in the immersion environment of methanol liquid, thereby diluting and pressurizing the methanol mist.

[0037] The inner cavity of the tank body 1 is provided with a float chamber 11, on which an atomizer 12 is fixedly mounted. The atomizer 12 is a microwave atomizer. With the help of the float chamber 11, the microwave atomizer floats on the surface of the liquid and atomizes the liquid fuel in the tank body. The microwave atomization technology can improve the atomization efficiency and atomization quality, making the output methanol aerosol mixture more stable and uniform.

[0038] Microwave atomizer is a device that uses microwave energy to atomize liquid. It uses microwave energy to heat the liquid to a boiling state, thereby forming fine droplets. This atomization technology has a wide range of applications in many fields, such as pharmaceuticals, chemicals, food processing and environmental protection.

[0039] The main working principle of microwave atomizer is:

[0040] 1. Microwave heating: Microwave energy is absorbed by the liquid, causing the liquid to heat up rapidly.

[0041] 2. Liquid boiling: When the liquid temperature reaches the boiling point, a large number of bubbles are generated on the surface and inside the liquid.

[0042] 3. Droplet formation: When the bubbles burst, the liquid is ejected into fine droplets.

[0043] Compared with traditional atomization methods, microwave atomization has the following advantages:

[0044] 1. Efficient atomization: Microwave energy can directly heat the inside of the liquid, making the atomization process faster and more efficient.

[0045] 2. Uniform atomization: Microwave atomization can produce uniform droplets, thereby improving the atomization effect.

[0046] 3. Energy saving: The microwave atomizer has high energy utilization rate and can complete the atomization process in a shorter time, thus saving energy.

[0047] 4. Easy to control: The atomization process can be precisely controlled by adjusting the microwave power and atomization time.

[0048] Application areas include but are not limited to:

[0049] Pharmaceutical industry: used to prepare drug aerosols for the treatment of respiratory diseases.

[0050] Chemical industry: used to prepare various chemical aerosols and for homogeneous mixing during the reaction process.

[0051] Food processing: used to prepare aerosol of food additives for uniform spraying on food surface.

[0052] Environmental protection: used to prepare chemical reagent aerosol for waste gas treatment and to remove harmful gases.

[0053] In short, microwave atomizers have important application value in many industries by utilizing microwave energy to achieve efficient and uniform atomization process.

[0054] In the utility model, the working steps of the device are as follows:

[0055] During operation, methanol liquid is injected to a suitable liquid level through the liquid filling port 2 , and the liquid level can be monitored in real time through the liquid level observation window 10 .

[0056] With the addition of methanol liquid, the float chamber 11 will float up as the liquid level rises, driving the microwave atomizer to be located on the liquid surface.

[0057] After sealing the liquid filling port, the power is turned on. When the system pressure and temperature are within the normal range, the pressure sensor 5 and the temperature sensor 6 transmit signals to activate the heating coil 7 and the microwave atomizer.

[0058] At the same time, the pressure and flow of the compressed air passing through the stainless steel breathable steel and the one-way valve 9 can be adjusted.

[0059] Stainless steel can make compressed air form tiny bubbles, effectively controlling liquid fluctuations. Under the action of heating and microwave atomization, methanol liquid is converted into mist, and under the action of compressed air, a low-pressure and low-concentration methanol gas flow is formed and discharged through the gas outlet 3.

[0060] If the system pressure increases abnormally, the safety valve 4 will automatically open to release the pressure to ensure the safety of the equipment.

[0061] The electrical components mentioned in this article are all connected to the external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer, etc. Therefore, the structure and working principle of the system and circuit involved in the device are well-known technologies in the market and will not be described in detail here.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
