Description

Technical Field

[0001] The invention relates to the technical field of metal plate welding, in particular to a fume recovery and treatment device for metal plate welding. Background Art

[0002] Metal plate welding is a process of connecting metal plates together through heat or pressure. Common metal plate welding methods include arc welding, gas shielded welding, laser welding, stir friction welding, etc. When welding metal plates, it is necessary to consider factors such as metal type, plate thickness, welding position and required welding strength to select appropriate welding methods and welding materials. Welding can not only firmly connect metal plates together, but also ensure the sealing and structural strength of the connection parts. In the process of metal plate welding, a large amount of smoke is usually generated. In order to protect the environment, a metal plate welding fume recovery and treatment device is needed to treat the fume generated during metal plate welding.

[0003] Traditional metal plate welding fume recovery and treatment devices usually require a special suction device to absorb the fume generated during the metal plate welding process, and are generally used in a fixed location. During the treatment process, a filter is generally used to separate particles and gases. After the filter has been used for a period of time, the staff usually needs to replace the filter to ensure the quality of the filter.

The nozzle is installed in cooperation with the filter screen to facilitate the discharge of clean gas and cleaning of the filter screen.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. After the staff moves the equipment to the position where the metal plate welding fume needs to be treated, in order to ensure stability during the treatment process, the position of the equipment needs to be kept fixed. At this time, the staff operates the control switch group. After the control switch group is adjusted, the electric telescopic rod three starts to drive, and the telescopic end of the electric telescopic rod three drives the connecting plate to move downward, drives the fixed column to move, drives the two first limit columns on the rear side to move downward, drives the two fixed connecting plates to move, and drives the two first limit columns on the front side to move downward (during this process, the first limit columns always slide in the guide groove on the guide plate). At this time, the first limit column moves downward, driving the supporting leg to move downward synchronously until the lower end of the first limit column is stuck in the limit groove of the adjacent second limit column (at this time, the second limit column cannot rotate under the restriction of the first limit column, and the moving wheel cannot rotate), and the lower end of the supporting leg contacts the ground, which is convenient for movement and provides stable support when the device does not need to be moved.

[0021] 2. After the staff slides the slide plate into the interior of the mounting plate and inserts the pin into the two transversely connected slots and slides the slide plate into the mounting plate and connects it firmly, the staff puts the outlet pipe of the external air suction equipment into the interior of the connecting pipe. Then the staff rotates the swivel clockwise to drive the lever to rotate (the two connecting grooves on the connecting pipe provide a rotation avoidance for the lever during the process of the swivel driving the lever to rotate). At this time, the lever drives the adjacent connecting column to rotate. The connecting column slides and rotates in the driving groove on the lever, driving the splint to rotate. At this time, the splint rotates around the adjacent rotating shaft. The end of the splint close to the outlet pipe of the external air suction equipment gradually rotates close to the outlet pipe of the external air suction equipment and clamps the outlet pipe of the external air suction equipment. At this time, the staff inserts the plug into the jacks on the connecting pipe and the outer arc surface of the swivel in turn to ensure the stability of the clamping, so that the equipment can be suitable for different metal plate welding air suction equipment pipeline docking.

[0022] 3. In order to ensure the filtering quality of the filter, the filter needs to be cleaned after being used for a period of time. At this time, the staff operates the control switch group. After the control switch group is adjusted, the electric telescopic rod starts to drive, and the telescopic end of the electric telescopic rod drives the sealing plate to move to the left. At this time, the two pins 2 at the rear end of the sealing plate drive the lower end of the connecting rod to move to the left (the pins 2 slide and rotate in the grooves opened on the front side walls of the adjacent connecting rods). At this time, the connecting rod rotates around the adjacent mounting column, and the upper end of the connecting rod drives the filter to move to the right. At this time, the rear end of the filter slides inside the slide groove. The staff observes through the observation window. When the filter moves to the bottom of the nozzle (the sealing plate blocks the top of the absorption liquid tank to prevent the clean water from entering the absorption liquid tank and mixing with the absorption liquid when cleaning the filter, thereby reducing the decomposition efficiency of the absorption liquid), the staff operates the control switch group. After the control switch group is adjusted, the submersible water pump starts to drive. After the submersible water draws clean water from the water tank, it is sprayed out through the nozzle along the water pipe. At this time, the filter starts to be cleaned, which is convenient for cleaning the filter alone. Frequent replacement is not required, which greatly reduces the use cost of the metal plate welding fume recovery and treatment equipment. BRIEF DESCRIPTION OF THE DRAWINGS

In order to ensure the filtering quality of the filter screen 121, the filter screen 121 needs to be cleaned after being used for a period of time. At this time, the staff operates the control switch group 6. After the control switch group 6 is regulated, the electric telescopic rod 19 starts to drive, and then the telescopic end of the electric telescopic rod 19 drives the sealing plate 122 to move to the left. At this time, the two pin shafts 128 at the rear end of the sealing plate 122 drive the lower end of the connecting rod 125 to move to the left (the pin shaft 128 slides and rotates in the groove opened on the front side wall of the adjacent connecting rod 125).

The upper end of the connecting rod 125 drives the filter screen 121 to move to the right. At this time, the rear end of the filter screen 121 slides inside the slide groove 126. At this time, the staff observes through the observation window. When the filter screen 121 moves to the bottom of the nozzle 711 (the sealing plate 122 blocks the top of the absorption liquid tank 123 to prevent the clean water from entering the absorption liquid tank 123 and mixing with the absorption liquid when cleaning the filter screen 121, thereby reducing the decomposition efficiency of the absorption liquid), the staff operates the control switch group 6. After the control switch group 6 is regulated, the submersible water pump 17 starts to drive, and then the submersible water pump 17 absorbs the clean water in the water storage tank 7 and sprays it out through the nozzle 711 along the water pipe 71. At this time, the filter screen 121 starts to be cleaned. When When the absorption liquid needs to be replaced, the staff operates the control switch group 6. After the control switch group 6 is regulated, the electric telescopic rod 16 starts to drive, and then the extension of the electric telescopic rod 16 drives the baffle 15 to move backward. At this time, the discharge port is released, and the absorption liquid is discharged along the discharge port to the inside of the wastewater tank 4. After the absorption liquid is discharged, the staff operates the control switch group 6. After the control switch group 6 is regulated, the electric telescopic rod 16 starts to drive, and then the extension of the electric telescopic rod 16 drives the baffle 15 to move forward. At this time, the discharge port is closed. After the staff opens the replacement door on the left side of the shell 1, the new absorption liquid is poured into the absorption liquid tank 123, which is convenient for handling metal plate welding fumes and cleaning the filter.

[0040] The working principle of the metal plate welding fume recovery and treatment device provided by the present invention is as follows:

[0041] First, the staff moves the equipment to the position where the metal plate welding fume needs to be treated. At this time, in order to ensure stability during the treatment process, the position of the equipment needs to be kept fixed. At this time, the staff operates the control switch group 6. After the control switch group 6 is regulated, the electric telescopic rod three 56 starts to drive, and then the telescopic end of the electric telescopic rod three 56 drives the connecting plate 54 to move downward, and then drives the fixed column 53 to move, and then drives the two first limiting columns 57 on the rear side to move downward, and then drives the two fixed connecting plates 58 to move, and then drives the two first limiting columns 57 on the front side to move downward (in this process, the first limiting columns 57 always slide in the guide groove on the guide plate 52). At this time, the first limiting columns 57 move downward, thereby driving the supporting legs 55 to move synchronously. The first stopper 57 moves downward until the lower end of the first stopper 57 is stuck in the stopper groove of the adjacent second stopper 59 (at this time, the second stopper 59 cannot rotate under the restriction of the first stopper 57, and the moving wheel cannot rotate), and the lower end of the supporting leg 55 contacts the ground. Then the staff slides the slide plate 21 into the interior of the mounting plate 28 and inserts the latch 24 into the two transversely connected slots and slides the slide plate 21 into the mounting plate 28. After the connection is firmly connected, the staff puts the air outlet pipe of the external air suction equipment into the interior of the connecting pipe 22, and then the staff rotates the swivel 23 clockwise, thereby driving the lever 231 to rotate (in the process of the swivel 23 driving the lever 231 to rotate, the two connecting grooves on the connecting pipe 22 provide a rotation avoidance for the lever 231). At this time, the lever 231 drives the adjacent connecting column 27 to rotate, and the connecting column 27 both slides and rotates in the toggle groove on the lever 231, thereby driving the clamping plate 26 to rotate. At this time, the clamping plate 26 rotates around the adjacent rotating shaft 25, and then the end of the clamping plate 26 close to the air outlet pipe of the external air suction device gradually rotates close to the air outlet pipe of the external air suction device and clamps the air outlet pipe of the external air suction device. At this time, the staff inserts the plug column 29 into the jacks on the outer arc surface of the connecting pipe 22 and the rotating ring 23 in turn to ensure the stability of the clamping, and then the staff turns on the external air suction device, and the external air suction device starts to drive, and then the external air suction device absorbs the smoke during the metal plate welding process, and then discharges it from the air outlet pipe of the external air suction device along the connecting pipe 22 and the inlet pipe 3. The welding fume enters the interior of the ceramic cone barrel 10 through the inlet pipe 3 (the inner wall of the ceramic cone barrel 10 is smooth, and the particles in the welding fume will not remain), and then enters the interior of the absorption liquid bin 123 through the exhaust pipe 14. At this time, the welding fume reacts with the absorption liquid poured into the absorption liquid bin 123 by the staff in advance (in order to prevent the absorption liquid from flowing back, the absorption liquid poured into the absorption liquid bin 123 cannot exceed the lower edge of the rear end of the ceramic cone barrel 10). After that, some of the particles in the welding fume of the metal plate are decomposed, and a small amount of particles that cannot be directly decomposed float out of the absorption liquid with the rising of the gas. Then the gas rises and passes through the heat conducting plate 11. At this time, the welding fume exchanges heat with the heat conducting plate 11, and the heat in the heat conducting plate 11 is dissipated through the heat dissipation plate 111.Then the gas continues to rise, and when passing through the filter 121, the residual particles of the welding fume are separated by the filter 121, and the clean gas enters the exhaust pipe 8 along the collection pipe 81 and is discharged from the equipment. In order to ensure the filtering quality of the filter 121, the filter 121 needs to be cleaned after being used for a period of time. At this time, the staff operates the control switch group 6. After the control switch group 6 is regulated, the electric telescopic rod 9 starts to drive, and then the telescopic end of the electric telescopic rod 9 drives the sealing plate 122 to move to the left. At this time, the sealing plate 122 is behind The two second pins 128 at the ends drive the lower end of the connecting rod 125 to move to the left (the second pin 128 slides and rotates in the groove provided in the front side wall of the adjacent connecting rod 125). At this time, the connecting rod 125 rotates around the adjacent mounting column 127, and the first pin 124 slides and rotates in the adjacent groove, so that the upper end of the connecting rod 125 drives the filter screen 121 to move to the right. At this time, the rear end of the filter screen 121 slides inside the slide groove 126. At this time, the staff observes through the observation window that when the filter screen 121 moves to the bottom of the nozzle 711 ( The sealing plate 122 blocks the top of the absorption liquid tank 123 to prevent the clean water from entering the absorption liquid tank 123 and mixing with the absorption liquid when cleaning the filter screen 121, thereby reducing the decomposition efficiency of the absorption liquid). The staff operates the control switch group 6. After the control switch group 6 is regulated, the submersible water pump 17 starts to drive, and then the submersible water pump 17 absorbs the clean water in the water storage tank 7 and sprays it along the water pipe 71 through the nozzle 711. At this time, the filter screen 121 starts to be cleaned. When the absorption liquid needs to be replaced, the staff operates the control switch group 6. After the control switch group 6 is After the electric telescopic rod 16 is adjusted, the electric telescopic rod 16 starts to drive, and the extension of the electric telescopic rod 16 drives the baffle 15 to move backward. At this time, the discharge port is released, and the absorption liquid is discharged into the wastewater tank 4 along the discharge port. After the absorption liquid is discharged, the staff operates the control switch group 6. After the control switch group 6 is adjusted, the electric telescopic rod 16 starts to drive, and the extension of the electric telescopic rod 16 drives the baffle 15 to move forward. At this time, the discharge port is closed. After the staff opens the replacement door on the left side of the shell 1, the new absorption liquid is poured into the absorption liquid tank 123.
