As laser marking machines have diverse and flexible applications, the matching dust removal equipment needs to achieve good dust removal effect on fine dust while also being portable and flexible.

[0003] Existing wet scrubbing equipment typically uses a spray tower to form a flowing water curtain, continuously passing dust-laden gas through several water curtains for dust removal.

[0027] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the following description of the present invention with reference to the accompanying drawings is merely illustrative and not restrictive.

[0028] Where possible, the various embodiments described below can be rearranged to form other embodiments not shown in the following description; the various technical features described below can also be rearranged to form other embodiments not shown in the following description.

[0029] Example 1:

[0030] Please refer to the appendix. Figure 1 .

[0031] To address the technical problems of existing dust removal equipment's complex structure and poor performance in handling fine dust generated by laser marking machines, this embodiment provides an atomizing dust removal device for metal dust from laser marking machines. The device includes a sealed dust removal chamber 1, an atomizing nozzle 2 for continuously generating atomized liquid at the top of the chamber, and an air inlet 3 and a purified gas outlet 4 on the chamber. The air inlet is positioned no higher than the atomizing nozzle's mist outlet position, and the mist outlet position is no higher than the purified gas outlet. The atomizing nozzle converts the raw liquid into a mist, which is fully dispersed within the dust removal chamber. This ensures that the dust-laden gas entering through the air inlet fully contacts the atomized liquid, capturing, condensing, and settling the dust at the bottom of the dust removal chamber for collection. The dust-removed gas is then discharged through the purified gas outlet. The device is compact and portable, and effectively captures dust in the form of water mist, meeting the requirements for handling fine dust generated by laser marking machines. It can effectively solve the above-mentioned technical problems and is fully applicable to the field of dust removal for laser marking machines.

[0032] It is known that during laser marking, the material evaporates instantaneously due to localized high temperatures, resulting in metal dust particles that are much smaller than those from conventional metal cutting, sometimes reaching sub-micron levels—and can be termed fine dust. Furthermore, for alloy or coated materials, laser marking may generate more complex compounds, necessitating the removal of harmful substances to prevent direct emission. Because the metal dust generated by laser marking machines differs significantly in properties from that from conventional metal cutting, dust removal methods used for conventional metal dust are ineffective for laser marking.

[0033] Therefore, for the fine dust generated by laser marking, this embodiment uses an atomizing liquid with dispersing properties to capture it quickly and over a wide area. While achieving dust removal, it simplifies the device, making it adaptable to the flexible application scenarios of laser marking machines. When the atomizing dust removal device of this embodiment is working, the atomizing nozzle generates an atomizing liquid and evenly distributes it inside the dust removal chamber. Dust-laden gas is introduced through the air inlet, and upon contact with the atomizing liquid, the dust and gas separate. The dust combines and condenses upon contact with the atomizing liquid, falling to the bottom of the dust removal chamber to form a dust-laden liquid, while the gas is discharged through the purified gas outlet.

[0034] Furthermore, in the above design, the air inlet is positioned as low as possible below the atomizing nozzle and above the highest liquid level of the dust-laden liquid. This design maximizes the amount of dust-laden gas entering the bottom of the dust removal chamber, increasing its distribution range and thus increasing its contact area with the atomizing liquid. Additionally, the purified gas outlet is positioned as high as possible above the mist outlet to reduce the amount of atomized vapor or untreated dust-laden gas entering the purified gas outlet, and also to minimize the dust content in the gas entering the purified gas outlet.

[0035] During dust removal, the Brownian motion effect between the numerous tiny droplets in the atomizing liquid and the dust significantly enhances the collision probability. Simultaneously, the surface tension of the atomizing droplets can also adsorb charged dust particles, achieving a dual-effect capture. Furthermore, the atomizing liquid can be not only water mist but also contain weakly alkaline neutralizing agents such as sodium bicarbonate, which can better neutralize acidic substances generated by the high-temperature decomposition of laser coatings, preventing equipment corrosion or environmental pollution. It can also effectively combine with dust particles in dust-laden gases, increasing their weight and even causing them to clump together, thus facilitating aggregation and sedimentation. This is particularly effective for capturing submicron-level dust generated by laser marking.

[0036] Furthermore, the atomizing nozzle continuously generates atomized liquid, which is then evenly distributed throughout the dust removal chamber, effectively intercepting dust and thus achieving thorough dust removal of dust-laden gas, preventing dust from flying and eliminating static electricity. Moreover, the atomized liquid is lightweight, meaning that the volume of the liquid is increased within the dust removal chamber while maintaining the same mass, highlighting the device's compact and portable characteristics. This atomized dust removal device is particularly effective in laser marking machine applications, demonstrating significant dust removal efficiency.

[0037] In a preferred embodiment, the system further includes a pressure gauge 22 and several control valves 23; and the atomizing nozzle includes several groups of atomizing nozzles 21. The control valves control each group of atomizing nozzles respectively, facilitating more precise adjustment of the overall mist output of the atomizing nozzle. Furthermore, the operating status of the atomizing nozzle is determined by observing the pressure gauge reading, thus ensuring that the atomizing nozzle operates adjustablely within the normal pressure range.

[0038] In a further preferred embodiment, arranging the atomizing nozzle array helps to control the number of working atomizing nozzles through independent control valves, thereby classifying the mist output of the atomizing nozzles into different levels.

[0039] In another preferred embodiment, the top of the atomizing dust removal device is provided with at least two atomizing nozzles, and a control switch is provided for each atomizing nozzle, thereby achieving more precise control over the amount of mist output.

[0040] In another preferred embodiment, the air inlet is located at the top of the dust removal chamber and extends along the top of the chamber to its second end. By controlling the air inlet direction, the dust-laden gas can be transported as far as possible towards the bottom of the dust removal chamber, so that it can fully contact the evenly distributed atomized liquid in the dust removal chamber as it travels towards the purified gas outlet, thereby ensuring a good dust removal effect.

[0041] In another preferred embodiment, the air inlet is located on the side wall of the dust removal chamber. By controlling the air inlet position to be lower than the atomizing nozzle and making its opening face the bottom of the dust removal chamber, it is ensured that the dust in the dust-containing gas can fully contact the atomizing liquid, thereby optimizing the dust removal effect.

[0042] In another preferred embodiment, it further includes an exhaust pipe 41; the purified gas outlet is located at the top or side wall of the dust removal chamber; and the purified gas outlet is connected to the exhaust pipe for discharging the purified gas and condensing the small amount of atomized vapor entering the purified gas outlet and reflowing it back into the dust removal chamber.

[0043] In a further preferred embodiment, the air outlet pipe is arranged parallel to the length direction of the dust removal chamber, which can better condense and return the atomized liquid.

[0044] Example 2:

[0045] Please refer to the appendix. Figure 1 .

[0046] Based on Embodiment 1, this embodiment adds a liquid inlet module to the atomizing dust removal device, including a pressure pump 24, a liquid inlet pipe 25, and a raw liquid pipe 26. The first end of the pressure pump is connected to the raw liquid pipe, and a first shut-off valve is installed at the connection point. The second end of the pressure pump is connected to the second end of the liquid inlet pipe, and the first end of the liquid inlet pipe is connected to the atomizing nozzle. The raw liquid enters through the raw liquid pipe, is pumped into the liquid inlet pipe by the pressure pump, and is then transported to the atomizing nozzle to facilitate the generation of atomized liquid. The raw liquid pipe can be connected to an external liquid storage device to provide raw liquid to the atomizing dust removal device. The first shut-off valve controls the raw liquid inlet rate and can also close or open the raw liquid inlet. The raw liquid can be water, an acidic liquid, or an alkaline liquid, achieving dust removal while simultaneously destroying the polluting properties of harmful substances in the dust.

[0047] In a further preferred embodiment, a structure is added to the atomizing dust removal device to achieve self-priming internal circulation. This includes a liquid suction port 27 located on the side wall of the dust removal chamber. The suction port is connected to a pressure pump, and a screen and a second shut-off valve are installed at the connection point to draw the liquid phase from the dust-laden liquid into the atomizing nozzle for recycling. The screen's aperture is smaller than the minimum particle size of the solid phase, preventing the solid phase from entering the inlet pipe. The second shut-off valve opens or closes the suction port, thereby controlling the amount and rate of liquid phase drawn in during self-priming internal circulation.

[0048] In a further preferred embodiment, the screen can be integrated with a pressure sensor. By observing the pressure sensor reading, the content of solid phase drawn into the screen along with the liquid phase can be determined. When the content exceeds a set value, the second shut-off valve is closed and the first shut-off valve is opened, switching to the external liquid supply mode to prevent the screen from clogging and ensure stable atomization quality.

[0049] In a further preferred embodiment, the screen employs a double-layer stainless steel woven structure, thereby achieving efficient separation of residual solid phase from the inhaled liquid phase. Furthermore, this structure supports rapid disassembly and cleaning, is simple in design, and is suitable for applications such as laser marking machines that require simple and convenient dust removal mechanisms.

[0050] In another preferred embodiment, the inlet pipe may be equipped with a Y-shaped filter to further prevent the intake of solid phase from clogging the atomizing nozzle.

[0051] Example 3:

[0052] Please refer to the appendix. Figure 2 .

[0053] Based on Embodiment 1 or Embodiment 2, this embodiment provides an atomization dust removal device for metal dust from a laser marking machine, which further includes a drain port 5 and a switch valve at the bottom of the dust removal chamber. When the liquid phase of the dust-laden liquid participates in the self-priming internal circulation, the dust removal chamber continuously performs dust removal work. Therefore, the solid concentration in the accumulated dust-laden liquid will gradually increase. Thus, by adding a drain port at the bottom of the dust removal chamber, excess dust-laden liquid or dust-laden liquid with excessively high solid concentration can be discharged from the dust removal chamber.

[0054] In a further preferred embodiment, the bottom of the dust removal chamber is an inverted conical surface, and a drain port is opened at the position of the cone head to quickly settle the solid phase in the dust-laden liquid to the drain port.

[0055] Setting the bottom of the dust removal chamber to an inverted cone shape can encourage the solid phase in the dust-laden liquid to settle towards the location of the drain port as much as possible. It can also effectively prevent the suction port from sucking in too much solid phase and clogging the screen when the self-priming internal circulation is activated when the solid phase concentration increases.

[0056] Example 4:

[0057] Please refer to the appendix. Figure 2 .

[0058] Based on any of the atomizing dust removal devices in Examples 1-3, this embodiment provides an atomizing dust removal device for metal dust from a laser marking machine, which further includes a level gauge 6, an indicator light 7, and an observation window disposed on the side wall of the dust removal chamber. The level gauge is disposed along the length of the dust removal chamber and is used to observe the liquid level of the dust-laden liquid inside; the level gauge can be disposed on or outside the side wall. The indicator light is adjacent to the level gauge and disposed outside the dust removal chamber, used to observe the working status of the dust removal chamber. The observation window is disposed above the outer side wall of the dust removal chamber; the observation window is sealed and transparent, used to observe the concentration of the atomizing liquid in the dust removal chamber.

[0059] In a preferred embodiment, the level gauge is configured as an inductive level gauge, a transparent level gauge, a magnetic float level gauge, or a capacitive dual-redundant level gauge. Among these, the inductive level gauge has no moving parts and has a relatively reliable structure; the transparent level gauge is easily visible; the magnetic float level gauge is easy to maintain and highly adaptable; and the capacitive dual-redundant level gauge has high accuracy and good stability. All of these are suitable for the level gauge in this embodiment.

[0060] In another preferred embodiment, the indicator light can be a three-color LED (green, yellow, red). A green indicator light illuminates when the internal dust-laden liquid is at the normal level; a yellow indicator light illuminates when the internal dust-laden liquid level is too high and self-priming internal circulation can begin; a red indicator light illuminates when the dust-laden liquid is about to overflow, triggering a warning and requiring the discharge of some of the dust-laden liquid. By observing the indicator light status, the first and second throttling valves on the pressure pump side can be adjusted to activate self-priming internal circulation, or the valve at the drain outlet can be adjusted to discharge some of the dust-laden liquid.

[0061] In another preferred embodiment, a laser scattering sensor is integrated inside the observation window. By detecting changes in light transmittance, the atomization concentration is fed back in real time and the atomizing nozzle is linked to adjust the amount of mist output, thereby achieving controllable atomized liquid concentration.

[0062] In another preferred embodiment, the observation window covers the upper half of the dust removal chamber to better observe the degree of internal atomization.

[0063] In another preferred embodiment, a suitable supplementary light is provided at the edge of the observation window to assist in observing the internal fog flow field state during manual inspection.

[0064] In another preferred embodiment, several observation windows are provided to facilitate observation of the internal mist flow field from different angles, thereby obtaining more reliable observation conclusions on the concentration of the atomizing liquid.

[0065] Example 5:

[0066] Please refer to the appendix. Figure 1 , 2 .

[0067] Based on any of the atomizing dust removal devices in Embodiments 1-4, this embodiment provides an atomizing dust removal device for metal dust from a laser marking machine, which further includes a universal tube 32 and a suction pipe 31. The second end of the universal tube is connected to the first end of the suction pipe, and a fan 33 is provided at the connection point. The second end of the suction pipe is connected to an air inlet. When the fan is working, the dust-containing gas is drawn into the suction pipe from the universal tube and then enters the dust removal chamber through the air inlet.

[0068] This design uses a fan to provide power at the connection between the universal joint and the suction pipe, effectively guiding dust-laden gas into the dust removal chamber, improving gas flow efficiency, ensuring the smooth introduction of dust-laden gas and the high efficiency of the treatment process, simplifying the system structure and enhancing ease of operation.

[0069] In a further preferred embodiment, the diameter of the universal joint is smaller than that of the suction pipe. This design, based on Bernoulli's principle, increases the gas flow rate, thereby enhancing suction. Furthermore, the first end of the universal joint is a flared opening. This flared opening, combined with the universal joint design, increases the area covering the suction, enhances suction power, and is more compatible with the dust-laden gas outlet of the laser marking machine. The suction pipe is also equipped with an airflow regulating valve, which allows for flexible control of the flow rate of dust-laden gas entering the dust removal system according to actual needs. This helps optimize the aerodynamic characteristics during the dust removal process, ensuring that the gas enters the dust removal chamber at an appropriate rate, thereby improving the operational stability and efficiency of the entire dust removal structure.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
