Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology, specifically relating to the structure of a dust removal suction head and a dust removal system. Background Technology

[0002] Machine tools with drill bits generate a lot of dust in the air during the drill bit's operation. To remove the dust, traditional milling machines are equipped with protective baffles around them to prevent the chips and dust generated during milling from flying everywhere. The baffles can be made of transparent materials to facilitate observation of the milling process during operation. However, the chips and dust will be blocked by the baffles and concentrated in a local area, making them difficult to clean, and there will be a lot of dust in the working environment.

[0003] To avoid excessive dust in the work environment, related technologies employ vacuum cleaners for dust removal. For small milling machines, the vacuum cleaner nozzle is placed close to the milling area to remove debris and dust generated during milling. For large milling machines or locations with high milling workloads, multiple pipes are connected to various parts of the milling machine. However, regardless of whether the vacuum cleaner nozzle is placed close to the processing area or multiple pipes are connected to the worktable for even dust collection, some dust will still accumulate near its source. Over a long period of production and processing, this can lead to a gradual increase in dust concentration in the work environment, posing certain safety hazards.

[0004] Therefore, how to prevent dust or smoke from spreading in the air is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0028] This utility model provides a dust removal suction head structure, mainly including: an assembly ring 41 and a retaining ring 45, and a sealing element 48, wherein the retaining ring 45 is provided with the sealing element 48.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] First, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Secondly, this utility model is described in detail using structural diagrams, etc. When detailing the embodiments of this utility model, for ease of explanation, the schematic diagrams showing the structure of the dust removal suction head and the dust removal system will be partially enlarged, not according to general proportions. Furthermore, these schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include three-dimensional space with length, width, and depth.

[0032] Please see Figure 2 , Figure 2 This is a three-dimensional schematic diagram of the dust removal suction head structure of this utility model. Figure 2 As shown, the dust removal suction head structure includes: an assembly ring 41, a holding ring 45, and a seal 48. In use, the assembly ring 41 is used to abut against the vicinity of the lathe drill bit. The drill bit needs to pass through the holding ring 45. The surface of the drill bit and the holding ring 45 are sealed by the seal 48. When the dust removal system and the holding ring 45 are connected, the aerosol will concentrate near the working surface of the drill bit, that is, in the inner cavity of the holding ring 45, achieving the effect of dust removal at the source, thereby effectively solving the problem of incomplete aerosol removal leading to diffused air.

[0033] The surface of the assembly ring 41 is provided with an annular groove 42, and a magnetic suction element 43 is embedded in the annular groove 42. The magnetic suction element 43 is suitable for connecting the assembly ring 41 to the machine tool; the attraction force of the magnetic suction element 43 allows the suction head structure 4 to be adsorbed around the drill bit as a whole.

[0034] The holding ring 45 is fixedly connected to the bottom surface of the assembly ring 41 by multiple vertical ribs 44. The vertical ribs 44 form a viewing window. The drill bit passes through the center of the assembly ring 41 and the holding ring 45, with part of its length exposed in the viewing window formed by the vertical ribs 44. The holding ring 45 includes an upper opening 46 and a lower opening 47. In addition, for the sealing effect, the radius of the upper opening 46 is smaller than the radius of the lower opening 47. The diameter of the upper opening 46 is sufficient to pass through the drill bit. The lower opening 47 abuts against the surface of the workpiece through the sealing element 48. The generated dust is concentrated between the upper opening 46 and the lower opening 47 and is drawn away.

[0035] A seal 48 is disposed at the bottom of the retaining ring 45, with a portion of the seal 48 suspended below the retaining ring 45. The seal 48 includes a flexible ring adapted to abut against the surface of the workpiece. The top inner surface of the flexible ring abuts against the outer wall of the retaining ring 45 at a lower position, and the bottom surface of the flexible ring abuts against the surface of the workpiece, specifically the surface near the drilling location, i.e., the area near where dust is generated. The flexible ring is connected to the retaining ring 45 by a clamp, enabling the flexible ring to be replaced.

[0036] One end of the air pipe 49 is connected to the side wall opening of the pressure ring 45, and the other end is connected to the dust removal system. The air pipe 49 is used to draw away the smoke and dust between the upper opening 46 and the lower opening 47.

[0037] Please see Figure 1 and to Figure 3 , Figure 1 This is a three-dimensional schematic diagram of the dust removal system of this utility model; Figure 3 This is a partial cross-sectional structural diagram of the spray box of this utility model. (See Figures 1 to 12). Figure 3 As shown, a dust removal system includes a spray box 1, an exhaust fan 2, a wastewater tank 3, and the aforementioned suction head structure 4. The exhaust fan 2 is located at the top of the spray box 1, and its air inlet is connected to the top of the circulation chamber 11. The wastewater tank 3 is located below the spray box 1. The air pipe 49 of the suction head structure 4 is connected to the spray box 1. The exhaust fan 2 transports the dust from the suction head structure 4 to the spray box 1 through the air pipe 49. Specifically, the suction force generated by the exhaust fan 2 causes the airflow to enter the primary settling cylinder 7 from the suction head structure 4, then vortex through the transition pipe 6 into the settling chamber 12, and finally move towards the circulation chamber 11 at the inclined position of the second drain outlet 16 until it is discharged from the air inlet of the exhaust fan 2 to the outside of the spray box 1. During this process, the dust will undergo two dust settling processes, and the wastewater will be discharged into the wastewater tank 3.

[0038] 1. Spray box

[0039] The spray box 1 has a partition 15 inside, with two chambers on either side of the partition 15. One side of the partition 15 is a circulation chamber 11, and the other side is a settling chamber 12. The exhaust fan 2 is located at the top of the circulation chamber 11, and the bottom of the spray box 1 has a second drain outlet 16. The second drain outlet 16 is constricted and communicates with both the circulation chamber 11 and the settling chamber 12. Wastewater in the settling chamber 12 is suitable for discharge into the wastewater tank 3 through the second drain outlet 16. A first spray head 13 is located at the top of the settling chamber 12, and a second spray head 14 is located below the first spray head 13. The spray angle of the first spray head 13 and the second spray head 14 can cover the side wall of the partition 15 and the side wall of the spray box 1 to prevent caking.

[0040] II. Primary Settling Tank 7

[0041] A primary settling cylinder 7 is connected to one side of the settling chamber 12 via a transition pipe 6. The primary settling cylinder 7 has a circular cross-section, which causes the incoming airflow to form a vortex. The height of the transition cylinder is higher than that of the second spray head 14. Part of the water mist sprayed by the first spray head 13 flows into the settling chamber 12, while the rest flows through the transition pipe 6 into the primary settling cylinder 7. This allows the dust to form a vortex and move towards the transition pipe 6 under the action of the exhaust fan 2 after entering the primary settling cylinder 7. During this movement, some of the water mist sprayed by the first spray head 13 combines with the dust, achieving the first dust suppression effect. The resulting wastewater flows into the wastewater tank 3 through the first drain port 71. The top of the primary settling cylinder 7 is connected to the air pipe 49 of the suction head structure 4, and the bottom of the primary settling cylinder 7 is provided with the first drain port 71, which is connected to the wastewater tank 3 through a pipe.

[0042] III. Suction Head Structure 4

[0043] The suction head structure 4 includes an assembly ring 41, a holding ring 45, and a seal 48. In use, the assembly ring 41 is used to abut against the vicinity of the drill bit on the lathe. The drill bit needs to pass through the holding ring 45. The surface of the drill bit and the holding ring 45 are sealed by the seal 48. When the dust removal system is connected to the holding ring 45, the aerosol will concentrate near the working surface of the drill bit, that is, in the inner cavity of the holding ring 45, achieving the effect of dust removal at the source, thereby effectively solving the problem of incomplete aerosol removal leading to diffuse air.

[0044] IV. Sewage Tank 3

[0045] The spray tank 1 is fixed to the ground by a mounting bracket. The sewage tank 3 is located below the mounting bracket, directly below the spray tank 1. The sewage tank 3 has a certain depth. After sewage enters, sedimentation and stratification will occur. The upper layer of water near the top of the sewage tank 3 is clearer and can be recycled. In addition, a float structure is installed on the mounting bracket. The float structure floats on the liquid surface of the sewage tank 3. The float structure is connected to the mounting bracket by a long rod. As the water level changes, the float structure drives the long rod to move up and down on the fixed bracket, which is conducive to observing the liquid level.

[0046] It should be further explained that, as a preferred embodiment, multiple partitions are fixed inside the sewage tank 3, which divide the sewage tank 3 into multiple areas. Sewage first enters the bottom of the first area through the pipe. The height of the partition in this area is less than the depth of the sewage tank 3, and the sewage entering the first area has a longer settling time. As the water level rises, the liquid level in the sewage tank 3 is higher than the height of the partition, and thus enters the second area, the third area, and so on until it enters the last area. At this time, the water in the last area is relatively clear. When circulating water, the inlet pipe 51 extends into the last area, and its height is slightly lower than the liquid level.

[0047] 5. Water circulation pump

[0048] A water circulation pump 5 is fixed on the spray box 1. The input end of the water circulation pump 5 extends to the top of the sewage tank 3 through the inlet pipe 51. The output end of the water circulation pump 5 is connected to the first spray head 13 and the second spray head 14 through the drain pipe 52. The water circulation pump 5 is used to recycle the clear sewage after sedimentation and stratification.

[0049] Therefore, the dust removal system of this utility model can extract smoke and dust at the source. The sealing element 48 set during dust removal improves the sealing effect and avoids the phenomenon of smoke and dust spreading. By setting up the spray box 1 and the primary settling cylinder 7, the smoke and dust are sprayed and settled twice, which effectively improves the settling effect. By setting up the circulating pump 5, water circulation is realized, which is energy-saving and environmentally friendly. In addition, by setting up the suction head structure 4, this utility model can arbitrarily install the suction head structure 4 on milling machines, lathes, drilling machines, laser welding machines and other equipment with drill bits that can generate smoke and dust, thus expanding the scope of application.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
