[0035] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] like Figures 1-6 As shown, a pipe grinding and dust removal device includes a frame 1, a collection hood 2, a dust collection box 3, a telescopic connecting sleeve 4, a lifting drive mechanism, and a negative pressure dust removal mechanism 5.

[0037] The collection cover 2 has an upward-facing collection cavity 6, and the bottom of the collection cover 2 is provided with a first communication port 7 that communicates with the collection cavity 6. The collection cover 2 is slidably connected to the frame 1 in the vertical direction.

[0038] The dust collection box 3 is connected to the frame 1 and located below the collection cover 2. The dust collection box 3 has a dust collection cavity 8 and a second communication port 9 at the upper end of the dust collection box 3 that communicates with the dust collection cavity 8.

[0039] The telescopic connecting sleeve 4 is installed between the collecting cover 2 and the dust collection box. The upper end of the telescopic connecting sleeve 4 is connected to the bottom of the collecting cover 2 and communicates with the first communication port 7. The lower end of the telescopic connecting sleeve 4 is connected to the upper end of the dust collection box 3 and communicates with the second communication port 9.

[0040] The lifting drive mechanism is connected to the collection cover 2 and is used to drive the collection cover 2 to rise so that the collection cover 2 covers the part of the pipe to be repaired;

[0041] The negative pressure dust removal mechanism 5 is connected to the dust collection chamber 8 in the dust collection box 3 and is used to draw air from the dust collection chamber 8. Specifically, firstly, the lifting drive mechanism drives the collection cover 2 to rise, and the raised collection cover 2 covers the part of the pipe to be ground. The negative pressure dust removal mechanism 5 draws air from the dust collection chamber 8, thereby creating a negative pressure environment in the dust collection chamber 8 and forming a negative pressure suction. Under the action of negative pressure suction, the dust generated from grinding the pipe will pass through the collection chamber 6, the first connecting port 7, the telescopic connecting sleeve 4, and the second connecting port 9 and enter the dust collection chamber 8. Then, the dust in the dust collection chamber 8 will be sucked away by the negative pressure dust removal mechanism 5. Thus, the dust generated from grinding the pipe can be collected and treated by negative pressure, avoiding dust from being dispersed in the air, preventing workers from inhaling dust, and improving the production environment in the workshop. More specifically, when the lifting drive mechanism drives the collection cover 2 to rise, the collection cover 2 will cover the part of the pipe to be ground, at which time the part of the pipe to be ground is located in the collection cavity 6; when the lifting drive mechanism drives the collection cover 2 to fall, the collection cover 2 will separate from the pipe, at which time the pipe can be transported and transferred. In this embodiment, the dust collection box 3 can be fixedly connected to the frame 1.

[0042] In this embodiment, the pipe material is a steel pipe, oil casing pipe, pipeline pipe, etc.

[0043] Specifically, the telescopic connecting sleeve 4 can be an accordion-style telescopic sleeve.

[0044] like Figures 1-3 As shown, the collection cover 2 may be provided with an upward-facing opening groove 10. The opening groove 10 is used for the pipe to be inserted and passed through when the collection cover 2 is raised, so that the collection cover 2 can cover the part of the pipe to be repaired.

[0045] like Figures 1-4 As shown, the lifting drive mechanism may include a lifting cylinder 11, which is connected to the frame 1 and the collection cover 2 and is used to drive the collection cover 2 to rise and fall; in this embodiment, there are two lifting cylinders 11.

[0046] like Figures 1-3 As shown, the collection cover 2 can be slidably connected to the frame 1 in the vertical direction by at least two guide rods 12; wherein, one end of the guide rod 12 is connected to the collection cover 2, and the guide rod 12 is slidably connected to the frame 1 in the vertical direction; in some embodiments, there are 4 guide rods 12.

[0047] like Figures 1-4As shown, the bottom of the dust collection box 3 may be provided with a first dust collection drawer 13; specifically, grinding the pipe will not only produce fine dust but also some larger impurities. These impurities cannot be sucked in by the negative pressure suction and will pass down through the collection inner cavity 6, the first connecting port 7, the telescopic connecting sleeve 4, and the second connecting port 9 before falling into the dust collection inner cavity 8 and onto the first dust collection drawer 13. When cleaning, you only need to pull out the first dust collection drawer 13 and empty it.

[0048] like Figure 1 , 5 As shown in Figures 6 and 7, the negative pressure dust removal mechanism 5 may include a cabinet 14, a negative pressure fan 15, and at least one dust removal filter cartridge 16.

[0049] The cabinet 14 is provided with a partition 17, which divides the cabinet 14 into an upper chamber 18 and a lower chamber 19.

[0050] The cabinet 14 is provided with an air inlet 20 communicating with the lower chamber 19 and an air outlet 21 communicating with the upper chamber 18. The air inlet 20 is connected to the dust collection chamber 8 in the dust collection box 3 through a pipe 22.

[0051] The partition plate 17 is provided with a third communication port 23 corresponding to the dust removal filter cartridge 16. The dust removal filter cartridge 16 is located in the lower chamber 19 and connected to the partition plate 17 and is aligned and connected to the corresponding third communication port 23.

[0052] The negative pressure fan 15 is installed in the upper chamber 18 and is used to draw air from the upper chamber 18 and discharge it from the air outlet 21. Specifically, after the negative pressure fan 15 draws air from the upper chamber 18 and discharges it from the air outlet 21, it creates a negative pressure environment in the upper chamber 18, thereby generating negative pressure suction. Under the action of the negative pressure suction in the upper chamber 18, the air in the dust collection chamber 8 is drawn through the pipe 22 and the air inlet 20 and enters the lower chamber 19. The air in the lower chamber 19 passes through the dust collector filter cartridge 16 and enters the interior of the dust collector filter cartridge 16. The dust collector filter cartridge 16 can filter out dust in the air. Then, the air inside the dust collector filter cartridge 16 passes through the third connecting port 23 and enters the upper chamber 18. Then, the air in the upper chamber 18 is drawn by the negative pressure fan 15 and discharged from the air outlet 21. The specific structures of the negative pressure fan 15 and the dust collector filter cartridge 16 are existing technologies well known to those skilled in the art, and will not be described in detail in this embodiment. More specifically, the upper chamber 18 is provided with a mounting plate, the negative pressure fan 15 is connected to the mounting plate, and the outlet of the negative pressure fan 15 is connected to the air outlet 21; in this embodiment, multiple dust collector filter cartridges 16 are provided.

[0053] like Figure 5 , 6 As shown, the negative pressure dust removal mechanism 5 may also include a back-blowing mechanism for blowing air into the dust removal filter cartridge 16 to blow off the dust adsorbed on the dust removal filter cartridge 16.

[0054] like Figure 5 , 6 As shown, the back-blowing mechanism may include an air storage tank 24, an air blowing pipe 25 corresponding to the dust removal filter cartridge 16, and a valve 26 corresponding to the air blowing pipe 25;

[0055] The gas storage tank 24 is used to receive and store pressurized gas, and the gas storage tank 24 can be connected to an external gas source;

[0056] The inlet of the valve 26 is connected to the gas storage tank 24;

[0057] One end of the air blowing pipe 25 is connected to the outlet of the corresponding valve 26;

[0058] The other end of the air blowing pipe 25 passes through the third connecting port 23 and extends into the corresponding dust collector filter cartridge 16. After a period of use, more and more dust accumulates on the dust collector filter cartridge 16. At this time, the valve 26 can be controlled to open so that the pressurized gas in the air storage tank 24 can be blown into the dust collector filter cartridge 16 through the air blowing pipe 25 for backflushing, thereby blowing off the dust adsorbed on the dust collector filter cartridge 16. In this embodiment, the air blowing pipe 25 corresponds one-to-one with the dust collector filter cartridge 16, and the valve 26 corresponds one-to-one with the air blowing pipe 25. The valve 26 can be a solenoid valve.

[0059] like Figure 1 , 5 As shown in Figure 6, the bottom of the cabinet 14 is provided with a second dust collection drawer 27, which is located below the dust removal filter cartridge 16. Specifically, the dust blown off the dust removal filter cartridge 16 can fall into the second dust collection drawer 27, and cleaning only requires pulling out the second dust collection drawer 27 and emptying it.

[0060] In summary, firstly, the lifting drive mechanism drives the collection cover 2 to rise, and the raised collection cover 2 covers the part of the pipe to be ground. The negative pressure dust removal mechanism 5 draws air from the dust collection cavity 8, thereby creating a negative pressure environment in the dust collection cavity 8 and forming a negative pressure suction. Under the action of negative pressure suction, the dust generated from grinding the pipe passes through the collection cavity 6, the first connecting port 7, the telescopic connecting sleeve 4, and the second connecting port 9 and enters the dust collection cavity 8. Then, the dust in the dust collection cavity 8 is sucked away by the negative pressure dust removal mechanism 5. Thus, the dust generated from grinding the pipe can be collected and treated by negative pressure, avoiding dust from being dispersed in the air, preventing workers from inhaling dust, and improving the production environment in the workshop.
