Description

Technical Field

[0001] The utility model relates to the technical field of laser surface treatment, in particular to a surface decontamination device combining laser treatment and vacuum adsorption. Background Art

[0002] When maintaining and overhauling power station equipment, it is often necessary to treat the rusty metal parts of the equipment. After treating the rusty parts, an anti-rust paint is applied to the surface to ensure the appearance of the equipment and extend its service life. At present, when removing rust from equipment, a wire brush is installed on an angle grinder for rust removal and grinding. Although good grinding effects can be achieved, there are also the following deficiencies: during grinding, the rust dust ground off is scattered with the high-speed rotation of the wire brush, causing environmental pollution around. In addition, in some special environments, after rust particles, dust, and broken bristles on the wire brush fall onto the equipment, it may cause short-circuit faults of the equipment. Therefore, before grinding, the equipment needs to be protected to prevent the equipment from being contaminated by rust dust and causing short-circuit accidents, but sometimes the protection workload is relatively large. Therefore, it is hoped to use a laser rust removal device for rust removal to prevent accidents caused by contamination of the equipment by rust particles, dust, etc.

[0030] The following will describe in detail the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0031] Please refer to Figure 1 、 2, a surface decontamination device combining laser treatment and vacuum adsorption, comprising a laser head 20 and a light guiding component 21, and further comprising a laser housing 10, an adsorption housing 30 and a blower 40. The adsorption housing 30 and the blower 40 are respectively installed at both ends of the laser housing 10. The laser head 20 is installed on the laser housing 10. The light guiding component 21 is located inside the laser housing 10 and extends towards the adsorption housing 30. The light guiding component 21 is connected to the laser head 20; a dust collection device is installed on the laser housing 10. When rust removal is carried out by laser, the blower 40 is turned on. Negative pressure is generated in the adsorption housing 30 by the blower 40, so as to absorb particulate matters and dust, and filter and collect them through the dust collection device, thereby preventing particulate matters and dust from polluting the equipment.

[0032] The laser head 20 and the light guiding component 21 are prior arts. When in use, the laser head 20 is connected to a laser generator through an optical fiber. In CN101947694A, a light guiding component 21 is disclosed. Specifically in this patent, the light guiding component 21 includes a light guiding tube 221, a reflection mirror 212 and a focusing adjustment device 213.

[0033] In order to protect the air outlet end of the blower 40, a protective net 41 is installed at the air outlet end of the blower 40. The blower 40 can be connected to the laser housing 10 by bolts.

[0034] In one of the solutions, the dust collection device is a filter bag tied to the blower 40. The filter bag is a prior art. A rope penetrates through the open end of the filter bag, and the filter bag is tied to the air outlet end of the blower 40 through the rope. The blower adopts a small axial flow blower. When in use, the adsorbed particulate matters and dust enter the filter bag after passing through the adsorption housing 30, the laser housing 10 and the blower 40.

[0035] In another solution, see Figure 2 , a partition 11 is arranged at one end of the adsorption housing 30 close to the blower 40. The partition 11 divides the inner cavity of the adsorption housing 30 into a dust suction cavity 12 and an air suction cavity 13. The blower 40 is installed at the end of the air suction cavity 13. A ventilation hole 14 is arranged at the position of the dust suction cavity 12 close to the partition 11. A dust collection cavity 15 is arranged at the corresponding position of the adsorption housing 30 for the ventilation hole 14. The dust collection cavity 15 is communicated with the air suction cavity 13. The dust collection device is a filter element 60 installed in the dust collection cavity 15. The open end of the filter element 60 is hermetically connected to the ventilation hole 14. Through the above structure, after the blower 40 is started, the adsorbed particulate matters and dust enter the inside of the filter element 60 after passing through the adsorption housing 30 and the laser housing 10, and thus are filtered and collected. The filtered gas is discharged from the air outlet of the blower 40. In this solution, the filter element 60 is a prior art, for example, a filter element with an opening at one end in a small vacuum cleaner is adopted.

[0036] Further, a end cover 16 is provided at the bottom of the dust collection chamber 15. The end cover 16 is rotationally connected and fixed to the dust collection chamber 15. The end cover 16 abuts against the bottom of the filter element 60 to fix the filter element 60. By providing the end cover 16, it is convenient to replace the filter element. When the end cover 16 is tightened, the bottom of the end cover 16 abuts against the filter element. There is a step in the ventilation hole 14, and the open end of the filter element has an annular rubber ring. The rubber ring is inserted into the ventilation hole 14 and abuts against the step. The end cover 16 is threadedly engaged and rotationally connected with the dust collection chamber 15. Under the extrusion of the end cover 16, the filter element 60 is fixed, and the sealing between the filter element 60 and the ventilation hole 14 is achieved.

[0037] In Figure 2 it is shown that the adsorption housing 30 includes an extension section 31 and a suction cup section 32 connected to one end of the extension section 31. The extension section 31 is connected to the laser housing 10, and a plurality of notches 321 are provided at the end of the suction cup section 32. By providing the notches 321, it is convenient for air to enter the adsorption housing 30. During use, the suction cup section 32 abuts against the surface of the equipment to be rust-removed, which can limit the distance between the laser and the equipment surface.

[0038] Further, a thread 311 is provided at one end of the extension section 31 away from the suction cup section 32. The extension section 31 is threadedly engaged and fixed with the laser housing 10. The threaded connection and fixation of the extension section 31 and the laser housing 10 facilitate replacement when the adsorption housing 30 is damaged.

[0039] See Figure 2 、 3 As shown in FIGS. 3 and 4, a wind guide ring 33 is further provided in the suction cup section 32. The wind guide ring 33 includes a first ring portion 331, a second ring portion 332, and a third ring portion 333. The outer circumference of the first ring portion 331 is connected to the inside of the suction cup section 32. The inner circumference of the first ring portion 331 is connected to one end of the second ring portion 332. The other end of the second ring portion 332 is connected to the third ring portion 333. A plurality of dust suction holes 334 are provided on the first ring portion 331. The third ring portion 333 is sleeved and supported outside the light guide assembly 21. With the above structure, while ensuring the ability to adsorb particulate matter and dust, it can support the light guide tube 221 and improve the stability of the light guide tube 221.

[0040] In this embodiment, the dust suction holes 334 are located at the outer edge of the first ring portion 331. Since during laser rust removal, the particulate matter falls downward and the dust diffuses in all directions, this can enable the particulate matter and dust to be adsorbed into the adsorption housing 30 from all around, making the particulate matter and dust as far away as possible from the end of the light guide assembly 21 and reducing the pollution at the end of the light guide assembly 21.

[0041] See Figure 2 、 3, an auxiliary device 50 is also provided on the laser housing 10. Specifically, the auxiliary device 50 can be a handle, which can be used for hand-holding; it can also be a connector connected to other devices, such as a connector connected to a robotic arm.

[0042] The working principle or operation process of the present utility model is as follows:

[0043] When the present utility model is in use, refer to Figure 2 , 3 , when rust removal is performed by laser, the blower 40 is turned on. The blower 40 causes a negative pressure to be generated inside the adsorption housing 30. Particulates and dust are sucked into the adsorption housing 30 from the dust suction holes 334. The adsorbed particulates and dust pass through the adsorption housing 30 and the laser housing 10 and enter the interior of the filter element 60, so as to be filtered and collected. The filtered gas is discharged from the air outlet of the blower 40, and the particulates and dust remain inside the filter element 60. After being used for a certain period of time, the filter element 60 is replaced.
