Description

Technical Field

[0001] The present invention relates to the technical field of welding fume processors, and particularly to a new type of energy-saving welding fume processor. Background Art

[0002] During the welding operation in the infrastructure production process, a large amount of fumes will be generated. These fumes contain various toxic substances that will cause great harm to the human body and seriously pollute the environment. The traditional infrastructure welding fume processor is large in volume and heavy in weight, making it inconvenient for workers to move and unable to be effectively used throughout the process. The power fan of the traditional infrastructure welding fume processor is arranged inside the processor body, and the air flow line is from top to bottom, which does not conform to the principle of hot air rising in thermodynamics. The negative pressure suction generated by the fan is greatly attenuated after passing through the filter element, the cavity of the body, and the flue duct wall, greatly reducing the suction effect on the welding fumes. The traditional infrastructure welding fume processor is powered by 380V or 220V AC voltage. The long-distance power supply line in a poor working environment is prone to breakage and leakage, posing a great potential safety hazard in electricity use. The traditional infrastructure welding fume collector cannot be used under the working conditions where gas welding and gas cutting do not require power supply.

[0003] Therefore, it is very necessary to propose a new type of energy-saving welding fume processor to solve the above problems. Summary of the Invention

[0028] The present invention provides a Figures 1 to 7 shown new energy-saving welding fume processor, including a suction fan head 1, a telescopic smoke exhaust pipe 2 and a processor body 3. Inside the processor body 3, there is a ventilation duct 15. Inside the ventilation duct 15, a mixed-flow fan 4 is fixedly installed. One end of the telescopic smoke exhaust pipe 2 is communicated with the suction fan head 1, and the other end of the telescopic smoke exhaust pipe 2 is communicated with the bottom end of the ventilation duct 15.

[0029] A magnetic attraction device 102 is fixedly connected to the outer wall of the suction fan head 1. The magnetic attraction device 102 can use a magnet. A multifunctional bracket 16 is movably arranged outside the suction fan head 1. During specific use, the suction fan head 1 is directly mounted above the welding point through the magnetic attraction device 102 or the multifunctional bracket 16.

[0030] An independent fan 104 is installed inside the suction fan head 1. A flow guide net 103 is arranged inside the suction fan head 1, which can achieve the filtering effect; a smoke induction probe 101 is installed on the inner wall of the suction fan head 1, which can detect the change of the smoke concentration generated during the welding process; and a processor is arranged inside the processor body 3 to cooperate with the smoke induction probe 101.

[0031] An air outlet 6 is arranged at the top of the processor body 3. A filtering device is arranged at the top end of the processor body 3. The filtering device includes a hazardous gas treatment device 8 and a multi-stage filtration device 9. The hazardous gas treatment device 8 is located above the multi-stage filtration device 9. The hazardous gas treatment device 8 includes structures such as activated carbon to purify the waste gas; the multi-stage filtration device 9 includes structures such as filter nets to intercept fine particles in the waste gas. And the hazardous gas treatment device 8 and the multi-stage filtration device 9 can be installed at the top of the processor body 3 by plugging, which is convenient for cleaning and replacement.

[0032] A control panel 5 is installed on the side wall of the processor body 3. On the control panel 5, there are an emergency stop button 501, a power indicator and a charging status indicator light 502, a first gear switch 503, a second gear switch 504, and an external power interface 505. The first gear switch 503 is used to control the independent blower 104; the second gear switch 504 is used to control the mixed-flow blower 4.

[0033] When performing welding operations, first place the suction nozzle 1 directly above the welding point through the magnetic attraction device 102 or the multi-functional bracket 16. The telescopic smoke exhaust pipe 2 extends or retracts as the suction nozzle 1 moves. Turn on the emergency stop button 501 on the control panel 5, and then turn on the first gear switch 503 and the second gear switch 504 in sequence, so that the independent blower 104 and the mixed-flow blower 4 operate simultaneously to form a coaxial suction force. In the manual mode, the first gear switch 503 and the second gear switch 504 can be adjusted differently according to the construction environment to adjust the motor speed to achieve the best processing effect.

[0034] In the automatic mode, when the smoke induction probe 101 does not receive the induction source (smoke) for a long time, the processor controls the first gear switch 503 and the second gear switch 504 to close, and the independent blower 104 and the mixed-flow blower 4 stop operating and enter the standby mode. When the smoke induction probe 101 receives the induction source (smoke), the processor controls the first gear switch 503 and the second gear switch 504 to open, and the independent blower 104 and the mixed-flow blower 4 enter the working mode, and can automatically adjust the motor speed according to the size of the welding fume and adjust the wind force to achieve the purpose of saving electricity and energy.

[0035] During welding operations, the suction nozzle 1 is equipped with an independent blower 104, which can directly act above the welding point smoke, quickly suck the welding fume into the telescopic smoke exhaust pipe 2 and transmit it to the ventilation duct 15 inside the processor body 3, accelerating the smoke collection efficiency and preventing the smoke from spreading outwards, and the gas flow rate is further increased after being pressurized by the mixed-flow blower 4.

[0036] By setting the harmful gas treatment device 8 and the multi-stage filtration device 9, the purpose of purifying the welding fume is achieved, and the design of the welding fume processor's filtered gas flow line from low to high conforms to the principle of hot gas rising in thermodynamics, reducing the flow resistance of the welding fume while also improving the filtration efficiency.

[0037] A handle 7 is fixedly connected to the top of the processor body 3, which is convenient for the operator to hold the handle 7 to move the welding fume processor. A bracket storage bin 10 is arranged on the side wall of the processor body 3.

[0038] A multi-functional touch panel 17, a gas detection probe 18, and a speaker 19 are installed on the side wall of the processor body 3.

[0039] An integrated circuit compartment 14 is provided inside the processor body 3 for arranging wires, etc., and a rainproof ventilation mesh window 12 is provided at the integrated circuit compartment 14 to improve the heat dissipation effect of the integrated circuit compartment 14 in the case of rain protection.

[0040] A DC power supply compartment 13 is provided at the bottom of the processor body 3, and a universal power supply unit 1301 of 60V or less is provided inside the DC power supply compartment 13. The universal power supply unit 1301 is a battery, which supplies power to the independent fan 104 and the mixed flow fan 4. A power supply quick socket body 1304 is provided at the top of the universal power supply unit 1301, and a plug connector 1302 and a socket 1303 are provided on the power supply quick socket body 1304.

[0041] The DC power supply compartment 13 and the logic processing center circuit module in the integrated circuit compartment 14 are connected to the manual control panel 5 and the multi-function touch panel 17 through the communication power supply line. The communication power supply line of the logic processing center circuit module in the integrated circuit compartment 14 is connected to the suction head 1 and the mixed flow fan 4. Manual control, related data query and parameter adjustment can be performed on the manual control panel 5 and the multi-function touch panel 17.

[0042] The welding smoke processor uses a DC power supply unit of 60V and below, which is highly safe and avoids electrical safety hazards such as wiring leakage during traditional construction. The quick-plug battery interface makes the power supply unit highly interchangeable and convenient for charging and replenishing energy, making smoke treatment more convenient for gas welding and gas cutting operations that do not require power.

[0043] The bottom end of the side wall of the processor body 3 is provided with a cleaning port 11, and a cover plate is provided at the cleaning port 11, and the cleaning port 11 cooperates with the vent 15. When there are many residues at the bottom of the vent 15, the cleaning port 11 can be used for cleaning.

[0044] During welding, the suction head 1 is first placed above the welding point using the magnetic suction device 102 or the multifunctional bracket 16 to collect smoke. The telescopic smoke guide pipe 2 is extended or shortened as the suction head 1 moves. The emergency stop button 501 is turned on the control panel 5. At this time, the multifunctional touch panel 17 is started at the same time. Then, the first gear switch 503 of the independent fan 104 of the suction head 1 and the second gear switch 504 of the mixed flow fan 4 are adjusted in turn to make the suction head 1 and the mixed flow fan 4 run at the same time to form coaxial suction.

[0045] When the concentration of harmful gases such as carbon monoxide or carbon dioxide in the welding operation space reaches the set dangerous value, the gas detection probe 18 will trigger the logic processing center in the integrated circuit compartment 14 to send a screen flashing alarm to the multi-function touch panel 17 and a warning sound of "Danger please evacuate" from the speaker 19 to remind personnel to evacuate to achieve the purpose of early warning.

[0046] The multi-functional touch panel 17 is operated through the touch screen buttons. The multi-functional touch panel 17 can record and display relevant data parameters such as temperature, humidity, smoke concentration, harmful gas concentration, and fan speed. The multi-functional touch panel 17 can realize the retrieval and query of various recorded parameters and the function settings of the parameters.
