Description
Technical Field
[0001] This invention relates to a laser cleaning machine, belonging to the field of laser rust removal technology. Background Technology
[0002] Metal workpieces will rust after being stored for a long time. At this time, it is necessary to use cleaning equipment to clean the rusted parts of the workpiece surface. Commonly used cleaning equipment includes laser rust removers and ultrasonic cleaners. At present, the application of laser rust removers is becoming more and more common.
[0003] Traditional laser rust removers come with a built-in dust collection device, which can absorb the metal dust generated by laser sintering or the gas generated by metal vaporization. Since the dust is easy to scatter and generate dust, it usually needs to be used in conjunction with a water mist spraying device. However, conventional water mist spraying devices will spray the atomized water droplets onto the surface of the workpiece after rust removal. This will cause the surface of the workpiece to become wet again after cleaning, thereby accelerating the repeated corrosion of the workpiece, which poses a certain problem. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a laser cleaning machine that solves the problem in the prior art where conventional water mist spraying devices spray atomized water droplets onto the surface of the workpiece after rust removal, which causes the cleaned surface of the workpiece to become wet again, thereby accelerating the repeated corrosion of the workpiece.
[0005] The technical problem to be solved by the present invention is achieved by the following technical solution: a laser cleaning machine, comprising...
[0006] The laser rust remover is electrically connected to an external power supply.
[0007] The dust collection bin is mounted on the laser rust remover. The bin is hollow, with through openings at both axial ends.
[0008] The suction device is installed at the axial end of the dust collection bin.
[0009] The guide blocks are fixedly installed in a ring shape inside the dustbin. Several guide blocks are provided, and they are evenly spaced along the axial direction of the dustbin.
[0010] A mixing pipe is installed inside the dustbin, with its axis aligned with that of the dustbin. The mixing pipe passes through a guide block, and several mixing pipes are arranged in a circular array at equal angles along the axis of the guide block. One end of each mixing pipe is connected to the suction device.
[0011] The air intake is located in the section of the mixing pipe between adjacent guide blocks.
[0012] The atomizing device is installed inside the dustbin and connected to the end of the mixing pipe away from the suction device.
[0013] The suction device draws gas from the dustbin through a mixing pipe, while the atomizing device sprays mist-like water droplets into the mixing pipe.
[0014] By adopting the above technical solution, the suction device extracts the gas from the dust collection bin, creating a negative pressure state inside. Gas from outside the dust collection bin enters through an opening at the other end, thus achieving the effect of adsorbing external air. When the laser rust remover operates, it cleans the rusted parts of the external metal surface, generating a certain amount of fine dust. This dust, along with the air, enters the dust collection bin and is sucked away by the suction device, achieving the purpose of dust removal. The dust entering the dust collection bin then enters the mixing pipe through the air inlet. At this time, the atomizing device sprays mist-like water droplets into the mixing pipe. The dust entering the mixing pipe through the air inlet then comes into contact with and combines with the mist-like water droplets. This prevents dust from scattering freely. The dust, combined with water droplets, then enters the suction device through the mixing pipe, achieving the purpose of dust removal and suppression. In this process, since the dust first enters the mixing pipe, the atomized water droplets and dust enter the suction device together under the suction force of the suction device. Compared with the traditional method of directly spraying atomized water droplets into the dust collection bin or the air inlet of the dust collection bin, this method can avoid the water droplets from accumulating and forming large water droplets or accumulating water in the dust collection bin or dripping onto the workpiece to be cleaned, thereby reducing the impact of atomized dust suppression on the cleaning and rust removal of the workpiece. At the same time, it avoids the situation where water droplets drip onto the already cleaned workpiece surface and cause the workpiece to rust again.
[0015] The present invention is further configured such that: the air intake device includes
[0016] The collection block is fixed to the opening end of the vacuum cleaner bin, and the collection block is connected to the end of the mixing pipe.
[0017] The exhaust pipe is located on the side of the collection block furthest from the dustbin. The exhaust pipe connects to the inside of the dustbin through the collection block, and the end of the exhaust pipe furthest from the collection block connects to the suction device.
[0018] The dust collection component, located inside the collection block, is used to block small solid particles in the air that enters the exhaust pipe through the collection block.
[0019] By adopting the above technical solution, the air is drawn out of the dust collection bin through the exhaust pipe and the collection block. The air in the dust collection bin first enters the mixing pipe and then is discharged through the collection block and the exhaust pipe, thereby creating a negative pressure inside the dust collection bin. At this time, the air outside the dust collection bin will carry the dust into the dust collection bin. The dust collection operation is completed through the above process, and the dust removal effect is achieved, which helps to reduce the degree of air pollution to the surrounding environment caused by laser cleaning operations.
[0020] The present invention is further configured such that: the dust collection assembly includes
[0021] A receiving cavity is located inside the collecting block, and an opening is formed along the curved surface of the collecting block. The mixing pipe is connected to the receiving cavity.
[0022] The collection box is detachably installed inside the storage cavity, and the collection box contains...
[0023] The collection chamber opens axially along the dustbin, and a filter screen is fixed to the opening on the side of the collection chamber away from the dustbin.
[0024] A sealing block is placed at the opening of the storage cavity to seal it.
[0025] By adopting the above technical solution, the dust and gas in the dust collection bin enter the mixing pipe through the air inlet and finally enter the collection chamber. Then, the gas enters the collection chamber through the opening and is blocked by the filter screen, leaving the dust particles in the collection chamber. As the suction equipment continues to work, the mixing pipe continuously supplies gas into the collection chamber. At this time, the dust remaining in the collection chamber cannot flow back into the mixing pipe. The remaining clean gas passes through the filter screen and enters the exhaust pipe and is discharged from the suction equipment, thereby achieving the purpose of dust collection. After the cleaning machine is used up, the dust in the collection chamber is removed by removing the sealing block and taking out the collection box. When taking out the collection box, the opening of the collection chamber should be vertically upward to prevent the dust in the collection chamber from falling out. Since the dust is adsorbed by the atomized water droplets, the dust will not fly around randomly when the collection box is taken out and poured out, reducing the impact of dust on the surrounding environment when the collection box is poured out.
[0026] The present invention is further configured such that: the atomizing device includes
[0027] The atomizing chamber is located inside the wall of the dust collection bin, and is connected to the end of the mixing pipe furthest from the collection block.
[0028] The water storage chamber is located inside the dust collection bin wall, on the side of the atomizing chamber away from the mixing pipe, and is connected to the atomizing chamber.
[0029] The atomizing nozzle is fixedly installed at the connection between the water storage chamber and the atomizing chamber. The atomizing nozzle has an input end and an output end. The output end of the atomizing nozzle faces the atomizing chamber, and the input end of the atomizing nozzle faces the water storage chamber.
[0030] The water inlet is located on the end wall of the water storage chamber away from the atomizing chamber.
[0031] One end of the water inlet pipe is connected to the water inlet hole, and the other end of the water inlet pipe extends to the outside of the dust collection bin and is connected to the water supply equipment.
[0032] By adopting the above technical solution, the water supply equipment injects water into the water storage chamber through the water inlet pipe and water inlet hole. After the water storage chamber is filled with water, the water is pressed out from the atomizing nozzle. The atomizing nozzle can atomize the water in the water storage chamber and spray it into the atomizing chamber. Then, following the air intake process of the above-mentioned mixing pipe, the mixing pipe draws the gas and atomized water droplets in the atomizing chamber into the mixing pipe, thereby combining with the dust in the mixing pipe and collecting it into the collection chamber for storage. The dust stored in the collection chamber cannot be scattered at will, thus achieving the dust reduction effect.
[0033] The invention is further configured such that: a second drain pipe is connected to the side of the atomizing chamber near the water storage chamber, and the end of the second drain pipe away from the atomizing chamber extends through the dust collection bucket to the outside of the dust collection bucket and is connected to the wastewater collection device.
[0034] By adopting the above technical solution, some heavier dust particles may settle into the atomization chamber due to gravity or the force of the suction after combining with water droplets. At this time, the atomization chamber will accumulate a mixture of water and dust on the side facing the water storage chamber. This mixture can be discharged through the second drain pipe and transferred to the wastewater collection device, thus preventing water from remaining in the atomization chamber and affecting the normal atomization. Water droplets will then enter the mixing pipe.
[0035] The invention is further configured such that: an air inlet connector pipe is provided at the opening of the dust collection bin away from the suction device, and an air inlet connector pipe is provided with...
[0036] Adjust the hose, connect it to the intake connector pipe, and seal the connection.
[0037] The vacuum head is fixed to the end of the adjusting hose furthest from the vacuum bin, and the vacuum head is connected to the inside of the vacuum bin through the adjusting hose.
[0038] By adopting the above technical solution, the opening end of the dustbin away from the suction device is the air inlet end. Installing an adjusting hose and a suction head at the air inlet end allows the position of the air inlet end of the dustbin to be changed by adjusting the position of the suction head, thereby increasing the freedom of adjustment of the air inlet end position of the dustbin and enabling users to adjust the air inlet end position of the dustbin in real time.
[0039] The invention is further configured such that the middle part of the adjusting hose is stacked along the axial direction of the dust collection bucket, and the adjusting hose can be stretched or compressed along the axial direction of the dust collection bucket.
[0040] By adopting the above technical solution, the adjusting hose is stacked along the axial direction of the dustbin. By unfolding or compressing the adjusting hose, the axial length of the adjusting hose can be changed, thereby further improving the adjustment range of the air inlet position of the dustbin.
[0041] The invention is further configured such that: a ring-shaped electromagnet is fixed inside the dust collection bin on the side away from the suction device; the electromagnet generates magnetism when energized; and the electromagnet is electrically connected to the laser rust remover.
[0042] By adopting the above technical solution, metal dust entering the dust collection bin may be unable to enter the mixing pipe through the air inlet due to the limited air intake of the suction device. At this time, this part of the dust will fall onto the guide block under the action of gravity and move towards the opening of the dust collection bin. When the metal dust passes by the electromagnet, it will be attracted by the electromagnet, thereby preventing the metal dust from falling from the opening of the dust collection bin to the outside of the dust collection bin, further reducing the impact of metal dust on the external environment.
[0043] The invention is further configured such that: a connecting block is provided on the outside of the laser rust remover, the connecting block is installed on the external rust removal equipment, a connecting ring is fixed on the connecting block, a total of multiple connecting rings are provided, the multiple connecting rings are distributed at equal intervals along the axial direction of the dust collection bucket, and the connecting rings are connected to the outside of the dust collection bucket.
[0044] By adopting the above technical solution, when the dust collection bucket is clamped on the connecting ring, the dust collection bucket and the connecting block can move synchronously. At this time, the external rust removal equipment drives the connecting block to rotate, thereby driving the dust collection bucket and the laser rust remover to rotate. This achieves the purpose of machine-controlled laser rust remover to automatically remove rust and clean the workpiece, eliminating the need for manual cleaning and reducing the labor intensity of manual labor.
[0045] The invention is further configured such that a handle is detachably and fixedly installed on the outer side of the laser rust remover away from the dust collection bin.
[0046] By adopting the above technical solution, a handle is installed on the laser rust remover, allowing manual operation of the laser rust remover to remove rust and clean the workpiece. This, combined with the machine-controlled laser rust remover for cleaning the workpiece, provides multiple operating modes for the laser rust remover, thereby improving the degree of freedom in operating the laser rust remover.
[0047] The beneficial effects of this invention are:
[0048] 1. Dust first enters the mixing pipe. Under the suction of the suction device, the atomized water droplets and dust enter the suction device together. Compared with the traditional method of directly spraying atomized water droplets into the dust collection bin or the air inlet of the dust collection bin to reduce dust, this method can avoid the water droplets from accumulating and forming large water droplets or water accumulating in the dust collection bin or dripping onto the workpiece to be cleaned. This reduces the impact of atomized dust reduction on the cleaning and rust removal of the workpiece. At the same time, it avoids the situation where water droplets drip onto the surface of the already cleaned workpiece and cause the workpiece to rust again.
[0049] 2. The water supply equipment injects water into the water storage chamber through the water inlet pipe and water inlet hole. After the water storage chamber is full, the water is pressed out from the atomizing nozzle. The atomizing nozzle can atomize the water in the water storage chamber and spray it into the atomizing chamber. Then, following the air intake process of the above-mentioned mixing pipe, the mixing pipe draws the gas and atomized water droplets in the atomizing chamber into the mixing pipe, thereby combining with the dust in the mixing pipe and collecting it into the collection chamber for storage. The dust stored in the collection chamber cannot be scattered at will, thus achieving the dust reduction effect.
[0050] 3. Some heavier dust particles may settle into the atomization chamber due to gravity or the force of the suction after combining with water droplets. At this time, a mixture of water and dust will accumulate on the side of the atomization chamber facing the water storage chamber. This mixture can be discharged through the second drain pipe and transferred to the wastewater collection equipment to prevent water from remaining in the atomization chamber and affecting the normal atomization. Water droplets will then enter the mixing pipe. Attached Figure Description

[0058] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this invention, the invention will be further described below in conjunction with specific illustrations.
[0059] like Figure 1-6 As shown, a laser cleaning machine includes a laser rust remover 10, a dust collection bin 20, a mixing pipe 40, an air inlet 41, guide blocks 42, an air suction device, and an atomizing device. The laser rust remover 10 is electrically connected to an external power supply. The dust collection bin 20 is fixedly installed on the laser rust remover 10 and is hollow, with through openings at both axial ends. A handle 11 is detachably and fixedly installed on the outer side of the laser rust remover 10 away from the dust collection bin 20. The air suction device is installed at the axial end of the dust collection bin 20. Several guide blocks 42 are fixedly installed in a ring shape inside the dust collection bin 20, and these guide blocks 42 are evenly spaced along the axial direction of the dust collection bin 20. A mixing pipe 40 is disposed inside the dust collection bin 20, with its axial direction aligned with that of the dust collection bin 20. The mixing pipe 40 passes through a guide block 42, and several mixing pipes 40 are arranged in a circular array at equal angles along the axis of the guide block 42. One end of each mixing pipe 40 is connected to a suction device. An air inlet 41 is located in the portion of the mixing pipe 40 between adjacent guide blocks 42. An atomizing device is installed inside the dust collection bin 20 and connected to the end of the mixing pipe 40 furthest from the suction device. The suction device draws gas from the dust collection bin 20 through the mixing pipe 40, while the atomizing device sprays mist-like water droplets into the mixing pipe 40.
[0060] like Figure 2-5As shown, the suction device includes an exhaust pipe 12, a collection block 23, and a dust collection assembly. The collection block 23 is fixed to the open end of the dust collection bin 20 and is connected to the end of the mixing pipe 40. The exhaust pipe 12 is located on the side of the collection block 23 away from the dust collection bin 20, and is connected to the interior of the dust collection bin 20 through the collection block 23. The end of the exhaust pipe 12 away from the collection block 23 is connected to the suction device. The dust collection assembly is located inside the collection block 23 and is used to block small solid particles in the air that enter the exhaust pipe 12 through the collection block 23. The dust collection assembly includes a sealing block 24, a collection box 25, a storage cavity 26, and a collection chamber 28. The storage cavity 26 is located inside the collection block 23 and has an opening along the curved surface of the collection block 23. The mixing pipe 40 is connected to the storage cavity 26. The collection box 25 is detachably installed inside the storage cavity 26. The collection box 25 contains a collection cavity 28, which opens axially along the dustbin 20. A filter screen 29 is fixed to the opening of the collection cavity 28 away from the dustbin 20. A sealing block 24 is installed at the opening of the storage cavity 26, sealing the storage cavity 26. A water collection cavity 37 is located within the collection block 23 on the side of the storage cavity 26 facing the dustbin 20. The water collection cavity 37 is directly connected to the storage cavity 26. The inner wall of the storage cavity 26 facing the dustbin 20 is an inclined surface that slopes towards the dustbin 20. The inclined surface slopes from the inner wall of the storage cavity 26 towards the connection point between the water collection cavity 37 and the storage cavity 26. A first drain pipe 13 is connected to the side wall of the water collection cavity 37 facing the dustbin 20. The other end of the first drain pipe 13 passes through the collection block 23 and extends to the outside of the collection block 23, where it collects wastewater. With the collection device connected, since the opening of the collection chamber 28 faces the dust collection bin 20, some of the dust in the collection chamber 28 will stick to the filter screen 29, and the other part will fall on the inclined surface of the storage chamber 26. At this time, the dust and atomized water droplets combine and gather on the inclined surface of the storage chamber 26 and slide in the refrigerator water collection chamber 37, and accumulate in the water collection chamber 37 to form mixed water. At this time, the mixed water can be discharged through the first drain pipe 13 to avoid excessive accumulation of water in the storage chamber 26, which would affect the air intake process from the opening of the mixing pipe 40.
[0061] like Figure 3 and Figure 4As shown, the atomizing device includes a water inlet pipe 15, a water storage chamber 33, a water inlet hole 34, an atomizing nozzle 35, and an atomizing chamber 36. The atomizing chamber 36 is located within the wall of the dust collection bin 20 and is connected to the end of the mixing pipe 40 away from the collection block 23. The water storage chamber 33 is located within the wall of the dust collection bin 20 and is situated on the side of the atomizing chamber 36 away from the mixing pipe 40. The water storage chamber 33 is connected to the atomizing chamber 36. The atomizing nozzle 35 is fixedly installed at the connection between the water storage chamber 33 and the atomizing chamber 36. The atomizing nozzle 35 has an input end and an output end. The output end of the atomizing nozzle 35 faces the atomizing chamber 36, and the input end of the atomizing nozzle 35 faces the water storage chamber 33. The water inlet hole 34 is located on the end wall of the water storage chamber 33 away from the atomizing chamber 36. One end of the water inlet pipe 15 is connected to the water inlet hole 34, and the other end of the water inlet pipe 15 extends to the outside of the dust collection bin 20 and is connected to the water supply equipment. A second drain pipe 14 is connected to the side of the atomizing chamber 36 near the water storage chamber 33. The end of the second drain pipe 14 away from the atomizing chamber 36 passes through the dust collection bin 20, extends to the outside of the dust collection bin 20, and is connected to the wastewater collection equipment.
[0062] like Figure 1 , Figure 3 and Figure 6As shown, an air inlet pipe 27 is provided at the opening of the dust collection bin 20 away from the suction device. An adjusting hose 21 and a suction head 22 are provided on the air inlet pipe 27. The adjusting hose 21 is threaded, snap-fitted, or plugged into the air inlet pipe 27, and the connection is sealed. The middle part of the adjusting hose 21 is stacked along the axial direction of the dust collection bin 20, allowing it to be stretched or compressed along the axial direction of the dust collection bin 20. The suction head 22 is fixed at the end of the adjusting hose 21 away from the dust collection bin 20, and communicates with the interior of the dust collection bin 20 through the adjusting hose 21. An annular electromagnet 32 is fixed inside the dust collection bin 20 on the side away from the suction device. The electromagnet 32 generates magnetism when energized and is electrically connected to the laser rust remover 10. The laser rust remover 10 has a connecting block 50 on its exterior, which is installed on the external rust removal equipment. Multiple connecting rings 51 are fixed to the connecting block 50 and are evenly spaced along the axial direction of the dust collection bin 20. The connecting rings 51 are connected to the exterior of the dust collection bin 20. An elastic sheet 30 is provided on the inner side of the dust collection bin 20 facing the air inlet connector pipe 27. The elastic sheet 30 is annular and forms an inflation chamber 31 with the inner wall of the dust collection bin 20. The inflation chamber 31 is sealed and separated from the inner wall of the dust collection bin 20. An air inlet pipe 16 is inserted and fixed into the dust collection bin 20. One end of the air inlet pipe 16 is connected to the inflation chamber 31, and the other end is connected to an external air supply device. After the external air supply device supplies air into the inflation chamber 31 through the air inlet pipe 16, the air pressure in the inflation chamber 31 increases, causing the elastic sheet 30 to expand and deform. Since the elastic sheet 30 is ring-shaped, part of the elastic sheet 30 expands towards the axis of the dust collection bin 20. At this time, the elastic sheet 30 gradually reduces the opening of the dust collection bin 20 away from the collection block 23. Since the power of the suction device remains unchanged, the amount of gas entering the dust collection bin 20 per unit time remains unchanged. As the opening of the dust collection bin 20 away from the collection block 23 gradually decreases, the flow rate of the gas through the inflation chamber 31 increases. At this time, the air flow rate in the inflation chamber 31 is greater than the air flow rate in the direction of the air inlet pipe 27. Therefore, the pressure in the inflation chamber 31 decreases, which helps to promote the gas to enter the dust collection bin 20 and improves the adsorption effect of the dust collection bin 20 on laser cleaning dust to a certain extent.
[0063] The suction device extracts the gas from the dust collection bin 20, creating a negative pressure inside. Gas from outside the dust collection bin 20 enters through the opening at the other end, thus achieving the effect of adsorbing external air. When the laser rust remover 10 operates, it cleans the rusted parts of the external metal surface, generating a certain amount of fine dust. This dust, along with the air, enters the dust collection bin 20 and is sucked away by the suction device, achieving the purpose of dust removal. The dust entering the dust collection bin 20 enters the mixing pipe 40 through the air inlet 41. At this time, the atomizing device sprays mist-like water droplets into the mixing pipe 40. The dust entering the mixing pipe 40 through the air inlet 41 mixes with the mist-like water droplets. The dust particles are combined with water droplets to prevent them from scattering. The dust particles, combined with water droplets, then enter the suction device through the mixing pipe 40, thus achieving the purpose of dust removal and suppression. In this process, since the dust particles first enter the mixing pipe 40, the atomized water droplets and dust particles will enter the suction device together under the suction force of the suction device. Compared with the traditional method of directly spraying atomized water droplets into the dust collection bin 20 or the air inlet of the dust collection bin 20 to suppress dust, this method can avoid the water droplets from accumulating and forming large water droplets or accumulating water in the dust collection bin 20 or dripping onto the workpiece to be cleaned, thereby reducing the impact of atomized dust suppression on the cleaning and rust removal of the workpiece. At the same time, it avoids the situation where water droplets drip onto the surface of the already cleaned workpiece, causing the workpiece to rust again.
[0064] The suction system draws air out of the dust collection bin 20 through the exhaust pipe 12 and the collection block 23. The air in the dust collection bin 20 first enters the mixing pipe 40 and then exits through the collection block 23 and the exhaust pipe 12, creating a negative pressure inside the dust collection bin 20. At this time, the air outside the dust collection bin 20 carries dust into the dust collection bin 20. Through the above process, the dust collection operation is completed, achieving the dust removal effect, which helps to reduce the degree of air pollution to the surrounding environment caused by laser cleaning operations. Due to the air intake limitation of the suction equipment, there is a possibility that some metal dust entering the dust collection bin 20 cannot enter the mixing pipe 40 through the air inlet 41. In this case, this part of the dust will fall on the inclined surface of the guide block 42 under the action of gravity and move along the inclined surface towards the opening of the dust collection bin 20. When the metal dust passes by the electromagnet 32, it will be attracted by the electromagnet 32, thereby preventing the metal dust from falling from the opening of the dust collection bin 20 to the outside of the dust collection bin 20 and reducing the impact of metal dust on the external environment. If the metal dust is not attracted by the electromagnet 32 when passing through it, the elastic sheet 30 can block some of the dust, preventing it from falling directly from the opening of the dust collection bucket 20 to the outside, thus further reducing the impact of the metal dust on the external environment.
[0065] Dust and gas in the dust collection bin 20 enter the mixing pipe 40 through the air inlet 41 and finally enter the collection chamber 26. Then, they enter the collection chamber 28 through the opening and are blocked by the filter screen 29, leaving the dust particles in the collection chamber 28. As the suction device continues to work, the mixing pipe 40 continuously supplies gas into the collection chamber 26. At this time, the dust remaining in the collection chamber 28 cannot flow back into the mixing pipe 40. The remaining clean gas passes through the filter screen 29 and enters the exhaust pipe 12 and is discharged from the suction device, thus achieving the purpose of dust collection. After the cleaning machine is used up, the dust in the collection chamber 28 is removed by removing the sealing block 24 and taking out the collection box 25. When taking out the collection box 25, the opening of the collection chamber 28 should be vertically upward to prevent dust from falling out of the collection chamber 28. Since the dust is adsorbed by the atomized water droplets, the dust will not fly around randomly when the collection box 25 is taken out and poured out, reducing the impact of dust on the surrounding environment when the collection box 25 is poured out. The water supply equipment injects water into the water storage chamber 33 through the water inlet pipe 15 and the water inlet hole 34. After the water storage chamber 33 is filled with water, the water is squeezed out from the atomizing nozzle 35. The atomizing nozzle 35 can atomize the water in the water storage chamber 33 and spray it into the atomizing chamber 36. Then, following the air intake process of the mixing pipe 40, the mixing pipe 40 draws the gas and atomized water droplets in the atomizing chamber 36 into the mixing pipe 40, thereby combining with the dust in the mixing pipe 40 and collecting it into the collection chamber 28 for storage. The dust stored in the collection chamber 28 cannot be scattered at will, thereby achieving the dust reduction effect.
[0066] Some heavier dust particles may combine with water droplets and settle into the atomizing chamber 36 due to gravity or the force of the suction. At this time, the atomizing chamber 36 on the side facing the water storage chamber 33 will accumulate a mixture of water and dust. This mixture can be discharged through the second drain pipe 14 and transferred to the wastewater collection device to prevent water from accumulating in the atomizing chamber 36 and affecting the normal atomization. Water droplets will then enter the mixing pipe 40.
[0067] The opening end of the dust collection bin 20 furthest from the suction device is the air inlet end. An adjusting hose 21 and a suction head 22 are installed at the air inlet end, allowing the position of the air inlet of the dust collection bin 20 to be changed by adjusting the position of the suction head 22. This increases the freedom of adjustment for the air inlet position of the dust collection bin 20, enabling users to adjust the air inlet position of the dust collection bin 20 in real time. The adjusting hose 21 is stacked along the axial direction of the dust collection bin 20. By unfolding or compressing the adjusting hose 21, its axial length can be changed, further increasing the adjustment range of the air inlet position of the dust collection bin 20.
[0068] When the dust collection bucket 20 is clamped onto the connecting ring 51, the dust collection bucket 20 and the connecting block 50 can move synchronously. At this time, the external rust removal equipment drives the connecting block 50 to rotate, thereby driving the dust collection bucket 20 and the laser rust remover 10 to rotate. This achieves the purpose of machine-controlled automatic rust removal and cleaning of the workpiece by the laser rust remover 10, eliminating the need for manual cleaning and reducing the labor intensity of workers. A handle 11 is installed on the laser rust remover 10, allowing workers to hold the laser rust remover 10 to remove rust and clean the workpiece. Combined with the aforementioned machine-controlled cleaning of the laser rust remover 10, this provides multiple operating modes for the laser rust remover 10, thereby increasing the degree of freedom in operating the laser rust remover 10.
[0069] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention, all of which fall within the scope of protection claimed by the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
