Description

Technical Field

[0001] This utility model belongs to the technical field of welding and cutting equipment, specifically relating to a pressureless diesel welding and cutting machine. Background Technology

[0002] Diesel fuel is a light petroleum product, a complex mixture of hydrocarbons, and is used as fuel for diesel engines. It is mainly blended from diesel fractions produced by processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced from shale oil processing and coal liquefaction. It is divided into two main categories: light diesel and heavy diesel.

[0003] Because diesel fuel has a high viscosity and low volatility, it may be difficult to achieve good atomization under unpressurized conditions. Poor atomization can lead to uneven mixing of diesel fuel and oxygen, which can affect combustion efficiency, prevent the flame temperature from reaching the ideal welding and cutting requirements, or cause incomplete combustion and carbon buildup. To address these issues, a device is needed that can improve the atomization effect of diesel fuel and ensure uniform mixing of diesel fuel and oxygen. Therefore, an unpressurized diesel welding and cutting machine is required. Utility Model Content

[0004] The purpose of this utility model is to provide a pressureless diesel welding and cutting machine with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A pressureless diesel welding and cutting machine includes a diesel tank, an oxygen tank on one side of the diesel tank, an oil inlet on the top of the diesel tank, and an oxygen injection pipe on the top of the oxygen tank. A one-way valve is fixedly connected to the top of the oxygen injection pipe. A diesel regulating valve and an oxygen regulating valve are respectively installed on the tops of the diesel tank and the oxygen tank. The diesel regulating valve and the oxygen regulating valve are respectively connected to an oil-resistant rubber hose and a rubber hose. One end of the oil-resistant rubber hose and the rubber hose are rotatably connected to an oil connector and an oxygen connector, respectively. One end of the oil connector and the oxygen connector are fixedly connected to a mixing chamber. One end of the oil connector extends through the mixing chamber and is located inside. A mixing component is installed inside the mixing chamber, and a cutting component is fixedly connected to one side of the mixing chamber.

[0007] As a further optimization of this utility model, the mixing component includes a guide plate fixedly disposed inside the mixing chamber. The guide plate is semi-arc-shaped and located below the oxygen connector. A rotating shaft is provided on the inner side of the mixing chamber via a bearing. Several stirring blades are fixedly installed on the outer surface of the rotating shaft. A ventilation hole is provided on one side of the guide plate. The ventilation hole is located on one side of the rotating shaft and cooperates with the stirring blades on one side of the rotating shaft.

[0008] As a further optimization of this utility model, the cutting assembly includes a cutting air pipe connected to one end of the mixing box, one end of the cutting air pipe is fixedly connected to a welding nozzle, and an adjustment valve is provided on the outer surface of the cutting air pipe.

[0009] As a further optimization of this utility model, the bottom of the diesel regulating valve is connected to the diesel tank, and the bottom of the oxygen regulating valve is connected to the oxygen tank.

[0010] As a further optimization of this utility model, the oil filling port is provided with an oil tank cover through its internal threads, the diesel tank is provided with an atomizing plate inside, and the surface of the atomizing plate is provided with atomizing holes.

[0011] As a further optimization of this utility model, a handle is fixedly installed on the top surface of the mixing tank, and arc-shaped handles are fixedly installed on the top of both the diesel tank and the oxygen tank.

[0012] The beneficial effects of this utility model are as follows: By installing an atomizing plate inside the diesel tank, when the diesel fuel moves upward due to the pressure difference, it is compressed into fine particles through the atomizing holes on the atomizing plate due to the interaction between the hole size, the surface tension of the diesel fuel, and the flow rate. When the atomized diesel fuel and oxygen enter the mixing chamber through the oil-resistant rubber tube and rubber hose, the oxygen and atomized diesel fuel are redirected by the guide plate and stirring blades inside the mixing chamber. This causes the atomized diesel fuel and oxygen to flow out directionally through the ventilation holes. Due to the size of the ventilation holes, the high-speed oxygen flow further divides the atomized diesel fuel passing through the ventilation holes, increasing the contact area between the atomized diesel fuel and oxygen. The outflowing oxygen and atomized diesel fuel drive the stirring blades located on the right side of the rotating shaft to rotate, allowing the atomized diesel fuel and oxygen to mix and rotate simultaneously along the stirring blades, thus achieving a better combustion effect.

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a pressureless diesel welding and cutting machine includes a diesel tank 1, with an oxygen tank 2 located on one side of the diesel tank 1. The diesel tank 1 and oxygen tank 2 are separable and can be used independently. Both the diesel tank 1 and oxygen tank 2 have a fixed arc-shaped handle 20 on their tops. An atomizing plate 18 is installed inside the diesel tank 1. During use, the atomizing plate 18 disperses diesel fuel into fine particles through physical conversion. The surface of the atomizing plate 18 has atomizing holes 22. During use, the diesel fuel passing through the atomizing holes 22 is compressed or sheared into fine particles due to the interaction between the hole size, surface tension, and flow rate. The faster the diesel fuel passes through the atomizing holes 22, the greater the shearing force and the finer the atomization. The bottom of a diesel regulating valve 6 is connected to the bottom of the diesel tank 1. During use, the diesel regulating valve 6 can precisely regulate the flow rate, pressure, and direction of the diesel fuel to meet different needs. It dynamically adjusts the diesel fuel supply according to the working conditions to ensure combustion efficiency. The bottom of an oxygen regulating valve 7 is connected to the bottom of the oxygen tank 2. In operation, the oxygen regulating valve 7 precisely regulates the flow rate, pressure, and direction of oxygen, dynamically adjusting the oxygen supply according to demand to ensure a precise ratio with diesel fuel and meet oxygen concentration requirements. The diesel tank 1 has an oil inlet 3 at its top, allowing diesel fuel to be added to maintain energy supply. An oil tank cover 4 is threaded inside the oil inlet 3 to prevent diesel evaporation and impurities from entering. The oxygen tank 2 has an oxygen injection pipe 5 at its top, delivering oxygen from the gas source to the oxygen tank 2 to ensure stable oxygen supply. A one-way valve 21 is fixedly connected to the top of the oxygen injection pipe 5, ensuring safe and stable oxygen delivery, controlling unidirectional oxygen flow, and preventing backflow. When the pressure inside the oxygen injection pipe 5 exceeds the pressure at the delivery end, the one-way valve 21 automatically closes, cutting off the backflow path.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the top of the diesel tank 1 is equipped with a diesel regulating valve 6 and an oxygen regulating valve 7. The diesel regulating valve 6 and oxygen regulating valve 7 are respectively connected to an oil-resistant rubber hose 8 and a rubber hose 9. During use, the oil-resistant rubber hose 8 is made of oil-resistant rubber material, which can resist the erosion of oily media, prevent the hose from expanding, dissolving, or becoming brittle, and can meet different pressure requirements. Its smooth inner layer reduces oil flow resistance and prevents leakage, and it has a wide temperature resistance range. The rubber hose 9 has a certain degree of elasticity and flexibility, which can form a good seal at the connection point to prevent oxygen leakage. During oxygen transportation, the rubber hose can... It provides a certain buffering effect. One end of the oil-resistant rubber hose 8 and the rubber hose 9 are respectively rotatably connected to the oil connector 10 and the oxygen connector 11. One end of the oil connector 10 and the oxygen connector 11 is fixedly connected to the mixing box 12. One end of the oil connector 10 extends through the mixing box 12 and is located inside. A handle 19 is fixedly installed on the top surface of the mixing box 12. In use, the oil hose 8 and the rubber hose 9 can be inserted into one end through the oil connector 10 and the oxygen connector 11 installed on one side of the mixing box 12, so that diesel and oxygen can be input into the mixing box 12. The oil hose 8 and the rubber hose 9 can also be disassembled.

[0022] like Figure 2 and Figure 4 As shown, the mixing chamber 12 is equipped with a mixing assembly, which includes a guide plate 14 fixedly disposed inside the mixing chamber 12. The guide plate 14 is semi-arc-shaped and located below the oxygen connector 11. In use, the semi-arc-shaped guide plate 14 can change the flow direction and path of oxygen. When oxygen impacts the surface of the guide plate 14, it is dispersed into airflow in multiple directions. When the oxygen is ejected at high speed from the oxygen connector 11, it carries a certain pressure. The guide plate 14 can buffer the oxygen, and the semi-arc structure can alleviate the impact force of oxygen, making the oxygen flow more stable. The inner side of the mixing chamber 12 is provided with a rotating shaft 15 rotatably connected by bearings. Several stirring blades 16 are fixedly installed on the outer surface of the rotating shaft 15. One side of the guide plate 14 is provided with a ventilation hole 17. The ventilation hole 17 is located on one side of the rotating shaft 15 and cooperates with the stirring blade 16 on the side of the rotating shaft 15. In use, some of the oxygen input from the oxygen connector 11 will flow out through the ventilation hole 17 on the guide plate 14. When the oxygen is sprayed out of the ventilation hole 17 at high speed, it will generate a certain impact force. The impact force will drive the stirring blade 16 located on the right side of the rotating shaft 15. Since the oxygen is continuously supplied, it will continuously drive the stirring blade located on the right side of the rotating shaft 15 to rotate counterclockwise. When the atomized diesel drips onto the guide plate 14, the oxygen will blow the diesel upward along the arc and cut the diesel, so that the diesel can pass through the ventilation hole 17 and mix evenly with the oxygen.

[0023] like Figure 1 and Figure 2As shown, a cutting assembly 13 is fixedly connected to one side of the mixing chamber 12. The cutting assembly 13 includes a cutting gas pipe 1301 connected to one end of the mixing chamber 12. During use, a mixture of oxygen and diesel atomized will flow inside the cutting gas pipe 1301 to prevent leakage. At the same time, the cutting gas pipe 1301 also has an anti-static function. A welding nozzle 1302 is fixedly connected to one end of the cutting gas pipe 1301. A regulating valve 1303 is provided on the outer surface of the cutting gas pipe 1301. During use, an igniter is provided on one side of the welding nozzle 1302 (not shown in the figure). The welding nozzle 1302 is the channel for outputting the mixed diesel and oxygen. The diesel and oxygen that are fully mixed in the mixing chamber 12 are transported to the welding nozzle 1302 through the pipe and then sprayed out from the nozzle of the welding nozzle 1302. The igniter ignites the mixed diesel and oxygen, which can make the sprayed mixed gas form a concentrated flame.

[0024] It should be noted that when using this pressureless diesel welding and cutting machine to weld and cut plates, first rotate the oil drum cap 4 to allow diesel fuel to enter the diesel drum 1 through the oil inlet 3. Then, rotate the oil drum cap 4 to seal the oil inlet 3. Next, insert the oxygen delivery pipe into the one-way valve 21 and use the oxygen injection pipe 5 to send oxygen into the oxygen tank 2. After the oxygen pipe has been injected, pull it out and connect the oil-resistant rubber hose 8 and the rubber hose 9 to the oil connector 10 and oxygen connector 11 on one side of the mixing box 12, respectively. Rotate to open the oxygen regulator. The throttle valve 7 and the diesel regulating valve 6 deliver oxygen into the mixing chamber 12 through the rubber hose 9. Because the mixing chamber 12 contains a guide plate 14, the direction of the oxygen is changed, creating a pressure difference with the oil connector 10. Due to this pressure difference, diesel fuel in the diesel storage chamber is drawn out. As the diesel fuel passes through the atomizing plate 18, it is compressed into fine particles by the interaction of the atomizing holes 22 on the atomizing plate 18 with the surface tension and flow rate of the diesel fuel. The initially atomized diesel fuel is then sent into the mixing chamber through the oil-resistant rubber hose 8. Inside the mixing chamber 12, a guide plate 14 and an agitator 16 are installed. The oxygen changes direction on the guide plate 14, causing the atomized diesel fuel to flow out directionally from the ventilation holes 17 on the guide plate. Due to the high-speed flow of oxygen through the ventilation holes 17, the atomized diesel fuel is further separated. The outflowing oxygen and atomized diesel fuel drive the agitator 16 located on the right side of the rotating shaft 15 to rotate, causing the atomized diesel fuel and oxygen passing through the ventilation holes 17 to mix and rotate simultaneously along the agitator 16, thus mixing the atomized diesel fuel and oxygen. While rotating, the mixture is evenly mixed. At this time, the operator holds the handle 19 to pick up the mixing box 12 and the cutting assembly, and then rotates to open the regulating valve 1303, so that the evenly mixed atomized diesel and oxygen are delivered into the welding and cutting nozzle 1302 through the cutting air pipe 1301. When the evenly mixed atomized diesel and oxygen are sprayed out from the welding and cutting nozzle 1302, the igniter is turned on to ignite the mixture and form a cutting flame, thereby cutting the plate until all the diesel and oxygen in the diesel tank 1 and oxygen tank 2 are used up.

[0025] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
