[0037] like Figure 1 As shown, a traditional method for removing rust from the outer wall of a pipe using a simple device in a squatting position involves placing the pipe 6 on a square timber 7 and manually removing rust from the outer wall of the pipe 6 using a simple device 5.

[0038] like Figures 2 to 12 The diagram shows an embodiment of a pipe rust removal device of the present invention, which includes a support frame 1 and a rust removal component connected to the support frame 1, and a recycling component. The recycling component includes a dust collection component connected to the support frame 1 and a dust collection component 23 connected to the dust collection component.

[0039] The method of using this utility model includes the following steps:

[0040] The movable support frame 1 drives the rust removal components to remove rust from the outer wall of the pipe, and the dust collection component collects the residue from the rust removal process into the dust collection component 23. This invention avoids squatting operations, thereby improving rust removal efficiency and reducing harm to the environment and human health.

[0041] In this embodiment, the dust collection assembly includes a fan, a fan housing 21, and a dust collection pipe 22. The fan housing 21 is connected to the support frame 1, and the fan is housed inside the fan housing 21. The fan housing 21 has an air inlet and an air outlet. The air inlet is connected to the dust collection pipe 22 through a dust collection assembly 23. Preferably, the dust collection pipe 22 is a flexible hose and can be made of plastic. By cooperating with the fan and the dust collection pipe 22, rust residue and dust during rust removal can be collected into the dust collection assembly 23, reducing the splashing of rust residue and dust and minimizing harm to the environment or human health.

[0042] In this embodiment, the recovery component also includes a filter assembly 24, which is connected to the fan housing 21 and positioned between the fan and the dust collection assembly 23. The filter assembly 24 includes a filter housing and a filter bag housed within it. The filter housing is detachably connected to the fan housing 21, and the filter housing and filter bag are also detachably connected. This detachable connection facilitates the cleaning of rust and powder and component replacement, reduces the risk of clogging, extends the service life of the device, and ensures cost-effective rust removal. Preferably, the filter housing is threadedly connected to the fan housing 21, and the internal space of the filter housing, the internal space of the fan housing, and the dust collection assembly 23 are interconnected. When the fan drives airflow to draw rust and dust from the suction pipe 22 into the dust collection assembly 23, most of the rust and dust falls into the dust collection assembly 23 due to gravity. A small portion of the rust and dust drawn into the filter assembly 24 is blocked by the filter bag, ensuring normal operation of the fan.

[0043] In this embodiment, the support frame 1 includes a handheld rod 11 and multiple clamps 12. The fan housing 21 is connected to the handheld rod 11 via the clamps 12, and the filter housing is also connected to the handheld rod 11 via the clamps 12. The recovery component also includes a connecting pipe 25. The filter assembly 24 is connected to the dust collection assembly 23 via the connecting pipe 25. The connecting pipe 25 can reduce the amount of rust and dust sucked into the dust collection assembly 24. The connecting pipe 25 not only serves as a connection but also extends the service life of the filter bag, reduces the frequency of filter bag replacement, and ensures rust removal costs. Preferably, the dust collection assembly 23 and the suction pipe 22 are also detachably connected, which facilitates residue cleaning and reduces the risk of blockage. The dust collection assembly 23 can be made by connecting a connecting pipe and a connecting plate. Specifically, it can be made of stainless steel by 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 suction pipes 22. The second connecting pipe is connected to the connecting plate and communicates internally with the first connecting pipe for installing the suction pipes 22, so that each suction pipe 22 is connected to the dust collection assembly 23. The first connecting pipe can form a receiving space in the dust collection assembly 23 for storing rust and dust. The first connecting pipe is connected to 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 handle 11 through the clamp 12. The bottom height of the dust collection assembly 23 is lower than the height of the connection between the dust collection assembly 23 and the suction pipe 22. When rust and other materials are sucked into the dust collection assembly 23 through the suction pipe 22, the rust and other materials can fall into the bottom of the receiving space in the dust collection assembly 23 for storage under the action of gravity. In this embodiment, the suction pipe 22 can be fastened to the dust collection assembly 23 by clamp 12, that is, the suction pipe 22 is clamped to the outside of the second connecting pipe by clamp 12. The hand handle 11 can be made of bent steel pipe, which can be used for connecting and supporting various components, and can also be convenient for construction personnel to operate by hand; the end of the hand handle 11 away from the rust removal component can be equipped with an anti-slip sleeve to facilitate personnel grip; the end of the hand handle 11 near the rust removal component can be flattened to connect with the rust removal component.

[0044] In this embodiment, the rust removal component includes a base 31 and at least one grinding element 32. The base 31 is connected to the support frame 1, and each grinding element 32 is rotatably connected to the base 31. Preferably, the base 31 is connected to the bottom of the hand handle 11, and the grinding element 32 is a bowl-shaped grinding steel brush.

[0045] In this embodiment, the rust removal component also includes a protective plate 33, which is connected to the base 31. The base 31 has a curved surface facing the pipe 6 and is adapted to the pipe 6. The base 31 can be made by bending steel plate. There are multiple protective plates 33, which are respectively disposed on both sides of the base 31. Each grinding component 32 is disposed between multiple protective plates 33. The protective plates 33 can be made by cutting soft rubber to block rust and dust generated during the rust removal of the pipe 6, prevent rust residue and dust from splashing, and facilitate the collection of rust residue and dust by the recovery component.

[0046] In this embodiment, the rust removal component also includes a motor 34 adapted to the number of grinding parts 32. The motor 34 is connected to the base 31 to drive the corresponding grinding parts 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 mounting base 343, and a fixing flange 344. The motor body 341 and the grinding parts 32 are respectively disposed on both sides of the base 31. The motor body 341 drives the grinding parts 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 parts 32, and both the locking nut 36 and the fixing flange 344 are threadedly connected to the rotating shaft 342. This allows the grinding parts 32 to be movably connected to the rotating shaft 342 to adjust the position of the grinding parts 32 along the length of the rotating shaft 342, improving the flexibility of the device when removing rust from different pipes 6, and also ensuring the stability of the grinding parts. The fixed stability after the position adjustment of 32 is ensured to prevent the grinding part 32 from moving axially along the rotating shaft 342 during rust removal operations. 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 seat 343. Preferably, the motor fixing seat 343 is internally connected to the motor protective cover 35. The base 31 has a rotating shaft mounting hole for inserting the rotating shaft and positioning the motor body 341. The empty part of the base 31 also has 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 removing rust and dust. In this embodiment, the dust suction pipe 22 is fastened and clamped to the outside of the dust suction positioning pipe by the clamp 12.

[0047] In this embodiment, a driving component is also 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 collection component via the wire 41. Preferably, the driving switch 42 is electrically connected to the rust removal component and the dust collection component via the wire 41. The driving switch 42 is connected to the handheld lever 11 for switching control. The support frame 1 also includes a power cord conduit 13. The wire 41 is inserted into the handheld lever 11. The wire 41 can also extend out of the handheld lever 11 and pass through the power cord conduit 13 to realize the electrical connection between the driving switch 42 and the motor 34. The embedded installation method of the wire 41 can reduce the risk of damage to the wire 41. Preferably, the driving switch 42 is also electrically connected to the fan. Multiple plugs are provided at the end of the wire 41.

[0048] The specific usage process of this embodiment is as follows:

[0049] Insert the multi-plug of wire 41 into the socket of the on-site distribution box, place the pipe rust removal device on pipe 6, turn on the drive switch 42, the grinding part 32 rotates, and the grinding part 32 moves along the outside of the pipe 6 through the support frame 1 to remove rust. The fan drives the air to flow from the air inlet of the fan housing 21 to the air outlet to suck the rust residue and dust during rust removal into the dust collection assembly 23 through the dust suction pipe 22. A small part of the rust residue and dust is sucked into the filter housing and blocked by the filter bag. The amount of rust residue and dust sucked into the filter assembly 24 can be reduced through the connecting pipe 25.

[0050] This embodiment is detachable, easy to assemble and disassemble, and convenient for storage, replacement, and maintenance; it has a simple structure, low processing cost, is reusable, and occupies little space; it avoids squatting operations, and standing construction ensures that the operator's head is away from the grinding head, which not only reduces the safety threat to the head, but also keeps the operator's head away from rust removal dust. With the addition of a recycling component, the harm of rust removal residue and dust to personnel or the environment can be further reduced; the device is easy to operate, and compared with the traditional use of simple devices for squatting operations, it can not only ensure construction costs, reduce the space requirements of the construction environment, but also improve rust removal efficiency.
