[0046] Embodiment two

[0047] As Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, based on Embodiment 1, the collection component 6 includes a collection box 601. A suction pump 602 is mounted on the side wall of the collection box 601 via a mounting base. The air inlet of the suction pump 602 is connected to the other end of the delivery pipe 5, and the output end of the suction pump 602 is connected to the inside of the collection box 601. An exhaust pipe 603 with a filter screen is connected to the side wall of the suction pump 602. The gas discharged from the collection box 601 is filtered through the exhaust pipe 603 with a filter screen and then transported to the outside, reducing the secondary pollution of the environment by gaseous pollutants.

[0048] A sealing cover 604 is rotatably connected to the top surface of the collection box 601. A spherical protrusion 605 is fixed to the bottom surface of the sealing cover 604. A handle 606 is fixed to the sealing cover 604. Two locking blocks 607 are symmetrically fixed to the side wall of the sealing cover 604. An opening groove 608 is opened at the lower end of the locking block 607, and a locking groove 609 is opened on the outer wall of the lower end of the locking block 607. The bottom surface of the locking block 607 is inclined. Two positioning posts 610 are symmetrically fixed to the outer wall of the collection box 601. A semi-semi ... The spherical block 611 and the hemispherical block 611 are engaged with the slot 609. The outer end of the positioning post 610 is fixed with a round block 612. The outer peripheral wall of the positioning post 610 is fitted with a spring 613. One end of the spring 613 abuts against the hemispherical block 611, and the other end of the spring 613 abuts against the round block 612. The hemispherical block 611 is engaged with the slot 609 to fix the locking block 607, ensuring the sealing of the collection box 601, preventing pollutant leakage and secondary pollution to the environment, and facilitating the opening and closing and fixing of the sealing cover 604.

[0049] The bottom of the collection box 601 is inclined, and a guide groove 614 is provided on the bottom of the collection box 601. A drain pipe 615 is fixed at the lower end of the collection box 601. A baffle 617 is inserted into the drain pipe 615 through a limiting groove 616. A cylinder 618 is installed on the outer wall of the collection box 601 through a mounting base. The bottom surface of the piston rod of the cylinder 618 is fixedly connected to the top surface of the baffle 617. The piston rod of the cylinder 618 pulls the baffle 617 to slide along the limiting groove 616, opening the drain pipe 615 to discharge the accumulated liquid contaminants to the outside for treatment.

[0050] When in use, the suction pump 602 is connected to the recovery component 3 through the delivery pipe 5 to form a negative pressure environment, which sucks up the water vapor, smoke and debris generated during the cutting process. These pollutants are sucked into the collection box 601, which facilitates the centralized collection of pollutants.

[0051] The bottom of the collection box 601 is inclined, allowing pollutants to slide naturally to the guide channel 614 under gravity. Some suspended pollutants accumulate on the bottom surface of the spherical protrusion 605 and drip from the center of the bottom surface of the spherical protrusion 605 into the collection box 601. When the pollutants accumulate to a certain level, the piston rod of the cylinder 618 pulls the baffle 617 to slide along the limiting groove 616, opening the drain pipe 615 to discharge the accumulated liquid pollutants to the outside for treatment. The gas discharged from the collection box 601 is filtered through the exhaust pipe 603 with a filter screen before being transported to the outside, reducing the secondary pollution of the environment by gaseous pollutants.

[0052] Pulling handle 606 rotates the sealing cover 604, facilitating the opening of the collection box 601 for cleaning residual contaminants. The locking block 607 on the sealing cover 604 engages with the hemispherical block 611 on the positioning post 610 on the outer wall of the collection box 601, further enhancing the sealing performance. When it is necessary to open the sealing cover 604, pulling handle 606 causes the sealing cover 604 to rotate synchronously with the locking block 607, which pushes the hemispherical block 611 to compress the spring 613. Slide along the positioning post 610 to separate the hemispherical block 611 from the slot 609; when closing the sealing cover 604, the locking block 607 is inserted into the positioning post 610 through the opening slot 608, and the inclined part at the lower end of the locking block 607 presses against the hemispherical block 611, so that the hemispherical block 611 is engaged with the slot 609, thus fixing the locking block 607, ensuring the sealing of the collection box 601, preventing pollutant leakage from causing secondary pollution to the environment, and facilitating the opening, closing and fixing of the sealing cover 604.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
