[0039] As Figure 1 shown, a traditional method for removing rust from the outer wall of a pipeline using a simple device for squatting operation. The pipeline 6 is placed on the square timber 7, and workers use the simple device 5 to remove rust from the outer wall of the pipeline 6.

[0040] As Figures 2 to 12 shown, a schematic diagram of an embodiment of a pipeline rust removal device of the present invention includes a support frame 1 and a rust removal component connected to the support frame 1, and further includes a recovery component. The recovery component includes a dust suction component connected to the support frame 1 and a dust collection component 23 communicated with the dust suction component.

[0041] On the other hand, the present invention also provides a method for using a pipeline rust removal device, including the following steps of use:

[0042] By moving the support frame 1, the rust removal component can be driven to move to remove rust from the outer wall of the pipeline. Through the dust suction component, the residues during rust removal can be collected into the dust collection component 23. The present invention can avoid squatting operation, thereby improving the rust removal efficiency and reducing the harm to the environment and the physical health of personnel.

[0043] In this embodiment, the dust suction component includes a fan, a fan housing 21, and a dust suction pipe 22. The fan housing 21 is connected to the support frame 1. The fan is arranged inside the fan housing 21. The fan housing 21 is provided with an air inlet and an air outlet. The air inlet is communicated with the dust suction pipe 22 through the dust collection component 23. Preferably, the dust suction pipe 22 is a flexible pipe and can be prepared from a plastic material. By the cooperation of the fan and the dust suction pipe 22, the rust slag and dust during rust removal can be collected into the dust collection component 23, reducing the splashing of rust slag and dust and reducing the harm to the environment or the health of personnel.

[0044] In this embodiment, the recycling component further includes a filtering assembly 24, which is connected to the blower housing 21 and disposed between the blower and the dust collection assembly 23. The filtering assembly 24 includes a filtering housing and a filter bag disposed inside the filtering housing. The filtering housing is detachably connected to the blower housing 21, and the filtering housing and the filter bag are also detachably connected. The detachable connection method facilitates the cleaning of rust slag and powder and the replacement of components, can reduce the risk of blockage, extend the service life of the device, and ensure the rust removal processing cost. Preferably, the filtering housing is threadedly connected to the blower housing 21, and the internal space of the filtering housing, the internal space of the blower housing, and the dust collection assembly 23 are interconnected. When the blower drives the air flow to drive the rust slag and dust to be sucked from the dust suction pipe 22 into the dust collection assembly 23, most of the rust slag and dust fall into the dust collection assembly 23 under the influence of gravity, and a small part of the rust slag and dust sucked into the filtering assembly 24 can be blocked by the filter bag to ensure the normal operation of the blower.

[0045] In this embodiment, the support frame 1 includes a hand-held rod 11 and a plurality of clamps 12. The blower housing 21 is connected to the hand-held rod 11 through the clamps 12, and the filter housing is also connected to the hand-held rod 11 through the clamps 12. The recovery component further includes a connecting pipe 25. The filter assembly 24 is communicated with the dust collection assembly 23 through the connecting pipe 25. The connecting pipe 25 can reduce the inhalation amount of rust slag and dust in the dust collection assembly 24. The connecting pipe 25 can not only play a connecting role, but also extend the service life of the filter bag, reduce the replacement frequency of the filter bag, and ensure the rust removal cost. Preferably, the dust collection assembly 23 and the dust suction pipe 22 are also detachably connected, which is convenient for residue cleaning and reduces the risk of blockage. The dust collection assembly 23 can be prepared by connecting a connecting pipe and a connecting plate. Specifically, stainless steel materials can be used for cutting and welding. In this embodiment, the dust collection assembly 23 includes a first connecting pipe, a connecting plate connected to the end of the first connecting pipe, and a second connecting pipe adapted to the number of the dust suction pipes 22. The second connecting pipe is connected to the connecting plate and the interior of the second connecting pipe is communicated with the first connecting pipe for installing the dust suction pipe 22, so that each dust suction pipe 22 is communicated with the dust collection assembly 23. The first connecting pipe can form a receiving space for the dust collection assembly 23 to store rust slag and dust. The first connecting pipe is communicated with the filter housing through the connecting pipe 25. The dust collection assembly 23 is also connected to the support frame 1 through the clamp 12. Preferably, the first connecting pipe is connected to the hand-held rod 11 through the clamp 12. The height of the bottom of the dust collection assembly 23 is lower than the height of the connection between the dust collection assembly 23 and the dust suction pipe 22. When rust slag and the like are sucked into the dust collection assembly 23 through the dust suction pipe 22, the rust slag can fall into the bottom of the receiving space in the dust collection assembly 23 under the action of gravity for storage. In this embodiment, the dust suction pipe 22 can be fastened to the dust collection assembly 23 through the clamp 12, that is, the dust suction pipe 22 is clamped outside the second connecting pipe through the clamp 12. The hand-held rod 11 can be prepared by bending a steel pipe, which can be used for connecting and supporting each component and is also convenient for the construction personnel to hold and operate. An anti-slip sleeve can be added to the end of the hand-held rod 11 away from the rust removal component to facilitate personnel to hold. The end of the hand-held rod 11 close to the rust removal component can be flattened to facilitate connection with the rust removal component.

[0046] In this embodiment, the rust removal component includes a base 31 and at least one grinding member 32. The base 31 is connected to the support frame 1, and each grinding member 32 is rotatably connected to the base 31. Preferably, the base 31 is connected to the bottom of the hand-held rod 11, and the grinding member 32 is a bowl-shaped grinding steel brush.

[0047] In this embodiment, the rust removal component further includes a protective plate 33. The protective plate 33 is connected to the base 31. The side of the base 31 facing the pipeline 6 is a curved surface and is adapted to the pipeline 6. The base 31 can be prepared by bending a steel plate. The protective plates 33 are multiple and are respectively arranged on both sides of the base 31. Each grinding member 32 is arranged between the multiple protective plates 33. The protective plate 33 can be prepared by cutting soft rubber, which is used to block the rust and dust generated during the rust removal of the pipeline 6, prevent the rust slag and dust from splashing, and facilitate the recovery component to collect the rust slag and dust.

[0048] In this embodiment, the rust removal component further includes a motor 34 that is adapted in number to the grinding members 32. The motor 34 is connected to the base 31 to drive the corresponding grinding members 32 to rotate. The rust removal component also includes a motor protective cover 35 and a locking nut 36. The motor 34 includes a motor body 341, a rotating shaft 342, a motor fixing base 343, and a fixing flange 344. The motor body 341 and the grinding members 32 are respectively disposed on both sides of the base 31. The motor body 341 drives the grinding members 32 to rotate through the rotating shaft 342. The locking nut 36 and the fixing flange 344 are respectively disposed on both sides of the grinding member 32, and both the locking nut 36 and the fixing flange 344 are threadedly connected to the rotating shaft 342. This can not only achieve the movable connection between the grinding member 32 and the rotating shaft 342 to adjust the position of the grinding member 32 along the length direction of the rotating shaft 342, improving the flexibility of the device when rust-removing different pipes 6, but also ensure the fixed stability of the grinding member 32 after the position adjustment, preventing the grinding member 32 from moving axially along the rotating shaft 342 during the rust removal operation. The motor protective cover 35 is connected to the base 31 to protect the motor 34. The motor body 341 is connected to the base 31 or the motor protective cover 35 through the motor fixing base 343. Preferably, the motor fixing base 343 is connected to the inside of the motor protective cover 35. The base 31 is provided with a rotating shaft mounting hole for inserting the rotating shaft and positioning the mounting position of the motor body 341. The remaining part of the base 31 is also provided with a dust suction pipe mounting hole, and a dust suction positioning pipe connected to the base 11 is provided at the dust suction pipe mounting hole. The dust suction positioning pipe is used to connect with the dust suction pipe 22 to serve as a suction channel for sucking rust and dust. In this embodiment, the dust suction pipe 22 is firmly clamped outside the dust suction positioning pipe through the clamp 12.

[0049] In this embodiment, a driving component is further included. The driving component includes a wire 41 and a driving switch 42 connected to the support frame 1. The driving switch 42 is electrically connected to the rust removal component and / or the dust suction component through the wire 41. Preferably, the driving switch 42 is electrically connected to the rust removal component and the dust suction component through the wire 41. The driving switch 42 is connected to the hand-held rod 11 for convenient switch control. The support frame 1 further includes a power cord pipe 13. The wire 41 is inserted into the hand-held rod 11, and the wire 41 can also extend out of the hand-held rod 11 and pass through the power cord pipe 13 to achieve the electrical connection between the driving switch 42 and the motor 34. The embedded installation method of the wire 41 can reduce the hidden danger of the wire 41 being damaged. Preferably, the driving switch 42 is also electrically connected to the blower; a multi-pin plug is provided at the end of the wire 41.

[0050] The specific use process of this embodiment is as follows:

[0051] Insert the multi - plug of the wire 41 into the socket of the on - site distribution box, place the pipe derusting device on the pipe 6, turn on the drive switch 42, the grinding part 32 rotates, and drives the grinding part 32 to move along the outer wall of the pipe 6 through the support frame 1 for derusting. The fan drives the air to flow from the air inlet of the fan housing 21 to the air outlet to suck the rust slag and dust during derusting into the dust collection component 23 through the dust suction pipe 22. A small part of the rust slag and dust is sucked into the filter housing and blocked by the filter bag. The inhalation amount of rust slag and dust in the filter component 24 can be reduced through the connecting pipe 25.

[0052] This embodiment is detachable, easy to assemble and disassemble, convenient for storage, replacement and maintenance; simple in structure, low in processing cost, reusable and small in occupied space; it can avoid squatting operation. Standing construction can ensure that the operator's head is far away from the grinding head, which can not only reduce the safety threat to the head, but also keep the operator's head away from the derusting dust. With the recycling components, it can further reduce the harm of derusting residues and dust to personnel or the environment; the device is easy to operate. Compared with the traditional squatting operation using simple devices, it can not only ensure the construction cost, reduce the space requirement for the construction environment, but also improve the derusting efficiency.

[0053] The above has described the embodiments of the present invention in detail, but the described content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
