A conveying frame 32 is movably clamped on the outer side of the limit frame 3. A separation box 4 is installed on the conveying frame 32. A sedimentation pipe 5 is provided on the top of the separation box 4. The top of the sedimentation pipe 5 is connected to an external exhaust device. The sedimentation pipe 5 and the separation box 4 are connected. When it is necessary to laser cut the parts, the transmission base 1 and the transmission plate 12 can be moved to drive the cutting head 2 to move, and laser cutting can be performed. The external exhaust device can be connected to the sedimentation pipe 5, and the smoke generated by the laser cutting can be sucked into the separation box 4 under the action of negative pressure, so as to ensure that the environment during the processing is not polluted by smoke and reduce the damage to the health of the operator. With the help of the separation box 4, part of the debris can be separated, and with the help of the sedimentation pipe 5, the smoke is circulated in the water to quickly screen out particulate suspended matter.

[0033] like Figure 4 and Figure 5 As shown, smoke and dust are easily attached to the guide plates 45 during the recovery process. Rectangular grooves are provided on the side walls at both ends of the separation box 4, and a rectangular frame 42 is installed inside the rectangular groove. A plurality of rotating shafts are rotatably provided inside the rectangular frame 42, and guide plates 45 are installed on the rotating shafts.

Excess debris and dirt can fall on the extension plate at the bottom. With the help of the adsorption sheets 451, excess oil and dirt inside can be absorbed, which is convenient for subsequent unified cleaning. In addition, the support rings 46 can knock and squeeze the bottom of the guide plate 45 during the movement of the guide plate 45, and can quickly shake off excess debris into the extension plate, which is convenient for subsequent unified cleaning and maintenance.

[0036] To facilitate subsequent separation processing, the top of the separation box 4 is open, and a sealing plate 41 is provided inside the separation box 4. A dust suction pipe 47 is installed at the bottom of the sealing plate 41. A circular groove is provided on the sealing plate 41, and a fixed sieve plate is installed inside the circular groove. The fixed sieve plate on the surface of the sealing plate 41 is used for the sedimentation pipe 5 and the dust suction pipe 47 to pass through. A plurality of arc grooves are provided on the side wall of the dust suction pipe 47, and the arc grooves are symmetrically arranged at both ends of the dust suction pipe 47. With the help of negative pressure, smoke and dust can be transmitted to the inside of the dust suction pipe 47.

[0037] like Figure 6 As shown, smoke can be separated during the transmission process, a circular groove begins to be formed at the bottom of the dust suction pipe 47, a reset plug rod 471 is inserted at the bottom of the dust suction pipe 47, the reset plug rod 471 is "U"-shaped and elastic, the top of the reset plug rod 471 is clamped at the bottom of the sealing plate 41, and a blocking disk 472 is installed at the bottom of the reset plug rod 471, the blocking disk 472 is elastic and the circular groove position corresponds, an adsorption shaft 48 is arranged inside the reset plug rod 471, the adsorption shaft 48 is an elastic grid tube and has activated carbon inside, and the adsorption shaft 48 is clamped inside the arc groove. When smoke enters the separation box 4 After the dust collection tube 47 is completed, the blocking disk 472 can be reset under the action of the reset rod 471, and the surface of the adsorption shaft 48 can be squeezed and cleaned with the help of the reset rod 471 to prevent the accumulation of dirt and sludge on the surface from affecting the subsequent screening efficiency.

[0038] like Figure 7As shown, in order to remove the high-temperature oil and harmful substances contained in the smoke, a clamping disc 511 is installed on the top of the sedimentation tube 5, and an air transmission hole is opened inside the clamping disc 511. A delivery pipe 51 is provided inside the sedimentation tube 5. A fixing ring is installed at the bottom of the side wall of the delivery pipe 51, and the fixing ring is connected to the inside of the sedimentation tube 5 to form an annular storage chamber. The top of the delivery pipe 51 is sealed, and a plurality of guide pipes 52 are installed on the delivery pipe 51. The guide pipes 52 are connected with the delivery pipe 51, and the guide pipes 52 are "J" shaped. The top of the guide pipe 52 is higher than the liquid level inside the sedimentation tube 5 to prevent backflow, and the smoke can be transferred to the water in the storage chamber to quickly separate the oil and harmful substances.

[0039] like Figure 8 As shown, in order to avoid backflow in the subsequent separation process, a through groove is opened at the top of the guide tube 52, and a movable rod 53 is inserted inside the through groove. The upper end of the movable rod 53 is a grid tube, and the lower end is a plastic shaft. A rubber ball is installed on the top of the movable rod 53, and a suspension ring 531 is clamped at the bottom of the movable rod 53. As the debris accumulates in the water, the liquid level will rise, and the suspension ring 531 can move under the action of buoyancy. When it reaches a certain limit and needs to be cleaned, the plastic part of the movable rod 53 can be against the inside of the guide tube 52, thereby stopping the smoke recovery, and the operator replaces the sewage to avoid incomplete subsequent smoke treatment.

[0040] like Fig. 9 As shown, in order to further separate the smoke, a screening ring 54 is installed at the bottom of the guide pipe 52, and water inlet rings are provided at both ends of the screening ring 54, and the water inlet rings are mesh plastic rings. Barrier tubes 55 are installed on both sides of the screening ring 54, and a plurality of water inlet holes are provided on the surface of the barrier tube 55 for separating larger debris. Under the action of negative pressure, the smoke flows along the guide pipe 52 into the sedimentation tube 5. With the help of the screening ring 54 and the barrier tube 55, the larger debris can be collected, and the remaining smoke enters the water for separation. The harmful substances in the smoke can be reduced by means of multi-layer screening, which can effectively improve the treatment effect.

[0041] Working principle: First, when it is necessary to perform laser cutting on parts, the driving base 1 and the driving plate 12 can be used to move the cutting head 2, so that laser cutting can be performed, and the external exhaust device can be connected to the sedimentation pipe 5, and the smoke and dust generated by the laser cutting can be sucked into the separation box 4 under the action of negative pressure, so as to ensure that the environment during the processing is not polluted by the smoke and reduce the damage to the health of the operators. With the help of the separation box 4, part of the debris can be separated, and with the help of the sedimentation pipe 5, the smoke can be circulated in the water, and the suspended particles can be quickly screened out, and the laser cutting of the equipment can be performed. When the smoke is removed, the position of the conveyor frame 32 can be adjusted to recover the smoke and dust according to the cutting direction. In the smoke and dust removal process, the position of the conveyor belt 43 can be adjusted according to the different materials being cut, thereby driving the guide plate 45 to move, and the air inlet direction of the air inlet can be controlled. Adjustments can be made for different materials to prevent the smoke and dust from spreading in the air. In addition, a small amount of particulate matter and debris mixed in some smoke and dust are likely to remain on the guide plate 45, and can fall onto the extension plate at the bottom of the guide plate 45 as they accumulate, and can be collected with the aid of the adsorption sheet 451.

[0042] Then, when the smoke enters the separation box 4, it can be separated from the suspended particles by the action of the airflow along the arc groove under the action of the adsorption shaft 48, and with the action of the airflow, the blocking plate 472 at the bottom can be adsorbed on the circular groove at the bottom of the dust suction pipe 47 by the airflow, which is used to drive the reset plug 471 to deform. When the smoke recovery and separation is completed, the blocking plate 472 can be reset under the action of the reset plug 471, and the surface of the adsorption shaft 48 can be squeezed and cleaned with the help of the reset plug 471 to prevent the accumulation of dirt and sludge on the surface from affecting the subsequent screening efficiency;

[0043] Finally, under the action of negative pressure, the smoke and dust flow along the guide pipe 52 to the inside of the sedimentation pipe 5. With the help of the screening ring 54 and the barrier tube 55, the larger debris can be collected, and the remaining smoke and dust enters the water for separation. The harmful substances in the smoke and dust can be reduced with the help of multi-layer screening. As the debris accumulates in the water, the liquid level will rise. The suspension ring 531 can move under the action of buoyancy. When it reaches a certain limit and needs to be cleaned, the plastic part of the movable plug rod 53 can be against the inside of the guide pipe 52, thereby stopping the smoke and dust recovery, and the operator replaces the sewage.

[0044] 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.
