[0004] To achieve the above objectives, the present invention provides the following technical solution: A plasma rapid cutting device and method for ultra-heat resistant gradient structure composite steel plate includes a guide rail for moving the cutting machine body, the cutting machine body, a moving frame, and a cutting head.

A first air inlet pipe and a second air inlet pipe are fixedly connected to one end of the dust collection shell. The other end of the first air inlet pipe is connected to an extraction unit. The other end of the second air inlet pipe is connected to a liquid tank. An exhaust pipe is installed inside the liquid tank. The exhaust pipe is connected to the extraction unit via a straight pipe. A control unit is installed inside the other end of the extraction unit. The extraction unit includes a column shell. A connection hole is opened on the inner side of the lower end of the column shell. A second one-way valve is installed inside the connection hole. A return spring is installed inside the column shell.
[0005] As a further optimization of the present invention, the blocking unit includes a horizontal plate, and a plurality of protrusions are linearly and equidistantly fixedly connected on the side of the horizontal plate away from the guide rail, and the vertical projection of the protrusions is semi-circular.
[0006] As a further optimization of the present invention, the dust removal shell includes a shell, one end of the shell near the cutting head is flared, and the other end of the shell has three through holes on its inner side. The two through holes at both ends are connected to the first air inlet pipe, and the middle through hole is connected to the second air inlet pipe.
[0007] As a further optimization of the present invention, there are two first intake pipes, each of which is L-shaped and connected to the interior of the column housing via a second one-way valve. The two first intake pipes are parallel to each other.
[0008] As a further optimization of the present invention, the liquid tank includes a tank body, an exhaust fan with a drying filter is installed on the upper side of the end of the tank body away from the cutting head, a cleaning solution is placed inside the lower end of the tank body, and the liquid level of the cleaning solution is set at the lower end of the second air inlet pipe and the exhaust fan.
[0009] As a further optimization of the present invention, the exhaust pipe includes a bend, a first one-way valve is installed on the inner side of one end of the bend, and the other end of the bend is located below the liquid level of the cleaning solution placed inside the box.
[0010] As a further optimization of the present invention, two straight pipes, two exhaust pipes, and two extraction units are provided, and the straight pipes, two exhaust pipes, and two extraction units correspond one-to-one. The straight pipes are used for communication between the bends and the cylindrical shell.
[0011] As a further optimization of the present invention, the control unit includes a control rod, one end of which is arc-shaped, and the other end of which is fixedly connected to a piston. The piston is slidably connected inside the cylindrical shell, and the arc-shaped end of the control rod is in close contact with the blocking unit.
[0012] As a further optimization of the present invention, the side of the return spring away from the cylindrical shell is in close contact with the inner wall of the cylindrical shell, and the cross-section of the return spring is oriented in the direction of the return spring.
[0013] As a further optimization of the present invention, the following steps are included: Step 1: Equipment operation: During the operation of the equipment, an external industrial power supply is used. During the operation of the equipment, the guide rail and the main body of the cutting machine cooperate with each other, and the cutting head is moved by the moving frame. During the movement of the cutting head, the cutting of the steel plate is completed. Step 2: Alternating air extraction and dust removal: During the movement of the mobile frame, the dust collection box moves synchronously. During the movement of the dust collection box, the control rods set inside the dust collection unit alternately contact the protrusions, thereby pushing the control rods to complete the reciprocating movement. During the reciprocating movement of the control lever, the piston moves synchronously. As the piston moves toward the liquid tank, it pushes the gas inside the cylinder shell into the liquid tank through the straight pipe, the curved pipe, and the first one-way valve. After entering the liquid tank, this gas comes into full contact with the cleaning solution placed inside the liquid tank to remove impurities from the gas. At the same time, it is discharged to the outside of the dust removal box by the exhaust fan. During this process, the cleaning solution inside the liquid tank will splash as the gas comes into contact with the cleaning solution. Step 3: Exhaust fan dust removal: The exhaust fan continuously exhausts the gas inside the chamber. During this process, the straight pipe continuously draws out the smoke and dust from inside the shell to clean the smoke and dust. At the same time, the smoke and dust drawn into the chamber comes into contact with the splashed cleaning solution, further improving the cleaning effect. Step 4: Post-maintenance: After the equipment has been running for a certain period of time, the staff will replace the cleaning solution inside the cleaning tank for subsequent processing.
[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the dust removal unit is set up to treat the smoke and dust by means of exhaust fan and suction. The suction is powered by the movement of the cutting machine body and can stably assist in the adsorption of smoke and dust, reducing the power requirements of the exhaust fan and effectively reducing energy consumption. 2. In this invention, by setting up a liquid tank, an exhaust pipe, an air extraction unit, and a dust removal shell, the smoke and dust entering the chamber can be mixed with the cleaning solution in a timely manner, which can improve the effect of smoke and dust treatment. In addition, the water mist splashed during the mixing process can further treat the gas entering the chamber through the second air inlet pipe, thereby comprehensively improving the effect of smoke and dust treatment. 3. In this invention, the reset spring is used to make the gas passing through the inside of the cylinder shell form a spiral, thereby accelerating the efficiency of gas entry and exit. This achieves piston reset control while guiding the gas flow, which has high practical value. Attached Figure Description

[0018] As a further implementation of this solution, the blocking unit 3 includes a horizontal plate 31. On the side of the horizontal plate 31 away from the guide rail 1, a plurality of protrusions 32 are linearly and equidistantly fixedly connected. The vertical projection of the protrusions 32 is semi-circular. Through the above arrangement, it is convenient to stably control the reciprocating movement of the control rod 781. As a further implementation of this solution, the dust collector 71 includes a housing 711. The end of the housing 711 near the cutting head 5 is flared. The other end of the housing 711 has three through holes 712 on its inner side. The two through holes 712 at both ends are connected to the first air inlet pipe 72, and the middle through hole 712 is connected to the second air inlet pipe 73. Through the above arrangement, the dust generated by the cutting head 5 during the cutting of the steel plate can be treated. As a further implementation of this solution, there are two first air inlet pipes 72. The first air inlet pipes 72 are L-shaped and are connected to the inside of the column housing 771 through the second one-way valve 774. The two first air inlet pipes 72 are parallel to each other. With the above arrangement, the smoke and dust generated during cutting can be extracted from multiple locations into the inside of the box 741. As a further implementation of this solution, the liquid tank 74 includes a tank body 741. An exhaust fan 742 with a drying filter is installed on the upper side of the end of the tank body 741 away from the cutting head 5. A cleaning solution is placed inside the lower end of the tank body 741. The liquid level of the cleaning solution is set at the lower end of the second air inlet pipe 73 and the exhaust fan 742. With the above settings, the smoke and dust entering the tank body 741 can be treated in a timely manner. As a further implementation of this solution, the exhaust pipe 75 includes a bend 751. A first one-way valve 752 is installed on the inner side of one end of the bend 751, and the other end of the bend 751 is located below the liquid level of the cleaning solution placed inside the housing 741. With the above arrangement, the problem of backflow of the cleaning solution placed inside the housing 741 can be prevented. As a further implementation of this solution, two straight pipes 76, two exhaust pipes 75, and two extraction units 77 are provided. The straight pipes 76, two exhaust pipes 75, and two extraction units 77 correspond one-to-one. The straight pipe 76 is used to connect the bend 751 and the cylindrical shell 771. Through the above arrangement, the overall stability of the equipment during operation can be further improved. As a further implementation of this solution, the control unit 78 includes a control rod 781. One end of the control rod 781 is arc-shaped, and the other end of the control rod 781 is fixedly connected to a piston 782. The piston 782 is slidably connected inside the cylindrical shell 771. The arc-shaped end of the control rod 781 is in close contact with the blocking unit 3. Through the above arrangement, the extraction of gas can be controlled by the movement of the piston 782. As a further implementation of this solution, the side of the return spring 772 away from the cylindrical shell 771 is in close contact with the inner wall of the cylindrical shell 771. The cross-section of the return spring 772 is oriented in the direction described above. With the above arrangement, the gas passing through the interior of the cylindrical shell 771 can be made to form a spiral by using the return spring 772, thereby accelerating the efficiency of gas entry and exit. As a further implementation of this solution, step 1: equipment operation: During the operation of the equipment, an external industrial power supply is used. During the operation of the equipment, the guide rail 1 and the main body of the cutting machine 2 cooperate with each other and use the moving frame 4 to drive the cutting head 5 to move. During the movement of the cutting head 5, the cutting of the steel plate is completed. Step 2: Alternating air extraction and dust removal: During the movement of the moving frame 4, the dust removal box 6 moves synchronously. During the movement of the dust removal box 6, the control rod 781 set inside the dust removal unit 7 alternately contacts the protrusion 32, thereby pushing the control rod 781 to complete the reciprocating movement. During the reciprocating movement of the control lever 781, the piston 782 moves synchronously. As the piston 782 moves toward the liquid tank 74, it pushes the gas inside the cylinder shell 771 into the liquid tank 741 through the straight pipe 76, the bent pipe 751 and the first one-way valve 752. After entering the liquid tank 74, this part comes into full contact with the cleaning solution placed inside the liquid tank 74 to remove impurities from the gas. At the same time, it is discharged to the outside of the dust removal box 6 through the exhaust fan 742. During this process, the cleaning solution inside the liquid tank 74 will splash as the gas comes into contact with the cleaning solution. Step 3: Exhaust fan dust removal: The exhaust fan 742 continuously exhausts the gas inside the housing 741. During this process, the straight pipe 76 continuously draws out the smoke and dust from inside the housing 711 to help clean the smoke and dust. At the same time, the smoke and dust drawn into the housing 741 comes into contact with the splashed cleaning solution to further improve the cleaning effect. Step 4: Post-maintenance: After the equipment has been running for a certain period of time, the staff will replace the cleaning solution inside the cleaning chamber 741 for subsequent processing.
