Technical Field

[0001] This utility model belongs to the field of additive manufacturing and relates to a dust removal device, and more particularly to a follow-up dust removal device. Background Technology

[0002] Arc welding equipment generates fumes during the printing of parts. If these fumes are not treated promptly and effectively, they can affect the workshop environment and pose a health hazard to workshop workers. Current methods to effectively solve the fume problem involve installing large dust hoods on top of the arc welding equipment, along with supporting structures and fume ducts, resulting in significant costs. Furthermore, this method hinders the hoisting or movement of the formed parts, making operation inconvenient. Additionally, the inaccessible dust hoods reduce workshop space and impede normal workshop operation. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A follow-up dust removal device is characterized in that: the follow-up dust removal device includes a sleeve, a dust discharge pipe, and a negative pressure suction device; the sleeve is generally in the form of a hollow cylindrical structure; the dust discharge pipe is disposed on the side of the sleeve and communicates with the inside of the sleeve; the negative pressure suction device is connected to the dust discharge pipe.

[0006] The aforementioned sleeve is provided with a set screw through hole along the radial direction of the sleeve. There are one or more set screw through holes. When there are multiple set screw through holes, the multiple set screw through holes are evenly distributed on the side wall of the sleeve.

[0007] The aforementioned follow-up dust removal device also includes a sealing plate disposed at the top of the sleeve; the sealing plate is generally annular; the outer diameter of the sealing plate is slightly smaller than the inner diameter of the sleeve.

[0008] The aforementioned sealing plate includes a first sealing piece and a second sealing piece that engages with the first sealing piece; the first sealing piece and the second sealing piece have the same structure and are both semi-circular.

[0009] The aforementioned sealing plate also includes connecting bolts; the first sealing plate is connected to the second sealing plate via the connecting bolts; the axial direction of the connecting bolts is parallel to the radial direction of the first sealing plate.

[0010] The aforementioned follow-up dust removal device also includes a dust intake pipe that is movably fitted outside the sleeve and moves freely along the axial direction of the sleeve.

[0011] The aforementioned smoke and dust intake pipe is connected to the sleeve by thread, snap-fit, or set screw.

[0012] The aforementioned smoke and dust intake pipe includes a cylindrical body and an annular nozzle; the cylindrical body is fitted outside the sleeve and can move freely along the axial direction of the sleeve; the annular nozzle is placed at the bottom of the cylindrical body; the outer diameter of the annular nozzle is smaller than the inner diameter of the cylindrical body; a smoke and dust passage window is provided between the annular nozzle and the cylindrical body.

[0015] The advantages of this utility model are:

[0016] This invention provides a follow-up fume removal device, including a sleeve, a fume discharge pipe, and a negative pressure suction device. The sleeve is a hollow cylindrical structure. The fume discharge pipe is located on the side of the sleeve and communicates with the inside of the sleeve. The negative pressure suction device is connected to the fume discharge pipe. In use, the sleeve is fitted over the welding torch, leaving a gap between them. When the welding torch is operating, the negative pressure suction device is activated, creating a negative pressure suction force in the fume discharge pipe and inside the sleeve, which then sucks away and collects the fume at the bottom of the welding torch. Because the sleeve and welding torch move together, the fume is sucked away and processed in real time when it is generated, resulting in higher fume processing efficiency. Furthermore, this invention eliminates the need for a large dust hood on top of the welding torch, increasing the utilization rate of workshop space. When fume treatment is complete, or when the welding torch needs maintenance or replacement, the sleeve can be easily removed from the welding torch. Obviously, the follow-up fume removal device provided by this utility model has the advantages of easy disassembly, no impact on the disassembly of the clamped substrate and parts, low cost, and strong adaptability to meet the needs of welding torches of different lengths.

[0023] See Figure 1 This utility model provides a follow-up dust removal device, including a sleeve 1, a dust discharge pipe 2, and a negative pressure suction device; the sleeve 1 is generally a hollow cylindrical structure; the dust discharge pipe 2 is located on the side of the sleeve 1 and communicates with the interior of the sleeve 1; the negative pressure suction device is connected to the dust discharge pipe 2. See also Figure 2 The following-motion fume removal device provided by this utility model involves fitting a sleeve 1 around the outside of the welding torch 5, with a gap between the sleeve 1 and the welding torch 5. When the welding torch 5 is operating, the negative pressure suction device is activated, creating a negative pressure suction force within the fume discharge pipe 2 and the sleeve 1, which then draws away and collects the fume from the bottom of the welding torch 5. Because the sleeve 1 and the welding torch 5 move in tandem, the fume is drawn away and processed in real time as it is generated, resulting in higher fume processing efficiency. Furthermore, this utility model eliminates the need for a large dust hood on top of the welding torch 5, increasing the utilization rate of workshop space. When fume processing is complete, or when the welding torch 5 needs maintenance or replacement, the sleeve 1 can be easily removed from the welding torch 5.

[0024] For example, the smoke and dust discharge pipe 2 can be connected to the negative pressure suction device via a PP flame-retardant pipe. The negative pressure suction device is a commonly used device, and its structure and operation are existing technologies, so they will not be described in detail here.

[0025] See Figure 1 as well as Figure 2 To facilitate the assembly of the sleeve 1 and the welding torch 5, the sleeve 1 used in this invention is provided with a set screw through hole along the radial direction of the sleeve 1. There may be one or more set screw through holes; when there are multiple set screw through holes, they are evenly distributed on the side wall of the sleeve 1. After the sleeve 1 is fitted onto the outside of the welding torch 5, the relative positions of the sleeve 1 and the welding torch 5 are adjusted, and then the two are connected by set screws. For example, three set screws can be used to fix the sleeve 1 and the welding torch 5 from different directions along the radial direction of the sleeve 1. When fume treatment is completed, the sleeve 1 can be removed from the outside of the welding torch 5 by loosening the set screws.

[0026] To improve the absorption of fumes, the follow-up fume removal device provided by this invention also includes a sealing plate 4 disposed at the top of the sleeve 1. The sealing plate 4 reduces the gap between the top of the sleeve 1 and the welding torch 5, ensuring a proper gap or opening between the bottom of the sleeve 1 and the welding torch 5, thereby ensuring efficient fume absorption. For example, the sealing plate 4 is generally annular; its outer diameter is slightly smaller than the inner diameter of the sleeve 1. The annular sealing plate 4 is fitted over the welding torch 5 and then placed on top of the sleeve 1.

[0027] For easy mounting of the sealing plate 4 onto the outside of the welding torch 5, see [link to documentation]. Figure 3 The sealing plate 4 used in this utility model includes a first sealing piece 41 and a second sealing piece 42 that engages with the first sealing piece 41. The first sealing piece 41 and the second sealing piece 42 have identical structures, both being semi-circular. After the first sealing piece 41 and the second sealing piece 42 are engaged, the entire structure forms a ring. For example, the sealing plate 4 also includes a connecting bolt 43; the first sealing piece 41 is connected to the second sealing piece 42 via the connecting bolt 43; the axial direction of the connecting bolt 43 is parallel to the radial direction of the first sealing piece 41. That is, the first sealing piece 41 and the second sealing piece 42 are engaged on the outside of the welding torch 5, and connected by the connecting bolt 43 to form an integral structure, which is finally placed on top of the sleeve 1.

[0028] See Figure 1 , Figure 2 as well as Figure 4The follow-up fume removal device provided by this utility model also includes a fume suction pipe 3 that is movably fitted outside the sleeve 1 and can move freely along the axial direction of the sleeve 1. The free movement of the fume suction pipe 3 along the axial direction of the sleeve 1 allows for easy adjustment of the relative position between the fume suction pipe 3 and the sleeve 1, accommodating welding torches of different lengths and offering greater adaptability. For example, the fume suction pipe 3 is connected to the sleeve 1 by a thread, a snap-fit ​​connection, or a set screw connection. Taking a threaded connection as an example, the inner wall of the fume suction pipe 3 is provided with an internal thread, and the outer wall of the sleeve 1 is provided with an external thread. The fume suction pipe 3 and the sleeve 1 are connected by a thread, and their relative position can be adjusted by adjusting the thread pitch when the fume suction pipe 3 is screwed on. When the fume suction pipe 3 and the sleeve 1 are connected by a set screw, one or more set screw through holes can be opened on the fume suction pipe along the radial direction of the fume suction pipe. After adjusting the relative position of the fume suction pipe 3 and the sleeve 1, they are fixed by the set screw. When the smoke suction pipe 3 and the sleeve 1 are connected by a snap-fit, for example, a spring-loaded ball can be installed on the outside of the sleeve 1. Multiple countersunk holes or through holes that match the ball are evenly distributed on the side wall of the smoke suction pipe 3. When it is necessary to adjust the relative position of the smoke suction pipe 3 and the sleeve 1, the smoke suction pipe 3 is pulled, causing the spring-loaded ball on the outside of the sleeve 1 to match the different countersunk holes on the smoke suction pipe 3, ultimately achieving the adjustment of their relative position. It should be noted that the structure of the spring-loaded ball, the method of setting the countersunk holes, the method of installing the spring-loaded ball, and the method of mating the spring-loaded ball with the countersunk holes are all existing technologies and will not be described in detail here.

[0029] See Figure 4 The fume extraction pipe 3 used in this invention includes a cylindrical body 31 and an annular suction nozzle 33 located at the bottom of the cylindrical body 31. The cylindrical body 31 is fitted outside the sleeve 1 and can move freely along the axial direction of the sleeve 1. A fume passage window 32 is provided between the annular suction nozzle 33 and the cylindrical body 31 to facilitate effective fume extraction. The outer diameter of the annular suction nozzle 33 is smaller than the inner diameter of the cylindrical body 31. On the one hand, the annular suction nozzle 33 is fitted outside the welding torch 5 to limit the position of the cylindrical body 31 and prevent the cylindrical body 31 from moving, thus ensuring the fume extraction effect. On the other hand, the fume passage window 32 between the annular suction nozzle 33 and the welding torch 5 can increase the probability of fume being extracted into the sleeve 1.

[0030] For example, the smoke inhalation pipe 3 and sleeve 1, as well as the sleeve 1 and smoke discharge pipe 2 used in this utility model can all be integral structures, such as being directly formed by 3D printing, which is also very convenient to use.
