Abstract
Description
Technical Field
[0001] This utility model relates to the field of rust removal technology, and in particular to a pneumatic slag removal and rust removal tool. Background Technology
[0002] Steel components inevitably rust during use, necessitating a rust removal tool. Chinese Patent Application No. 202021215856.8 discloses a rust removal device for steel structures, including a base. A fan is fixedly connected to the bottom and center of the base. A storage box is bolted to the bottom of the base and to the right of the fan. The exhaust port of the fan is connected to the storage box via a connecting pipe. An exhaust pipe is fixedly connected to the upper right side wall of the storage box. A filter screen is fixedly connected to the inner wall of the storage box and to the left of the exhaust duct. A discharge port is opened on the top of the storage box and slightly to the left. A flow guide plate is fixedly connected to the top of the base and close to the side wall. A handle is fixedly connected to the front side wall of the flow guide plate. A protective baffle is fixedly connected to the top of the flow guide plate. A first rust removal shaft is rotatably connected to the right inner wall of the protective baffle and slightly to the rear of the middle via a bearing. A rust removal motor is fixedly connected to the right side wall of the protective baffle and directly opposite the first rust removal shaft.
[0003] While the aforementioned technology achieves a certain degree of rust removal, when cleaning the top of magnetic steel components, the lack of a component to adhere it to the steel means that the operator must hold the device in place throughout the process. This requires not only applying force to move the device but also applying an upward force to prevent it from sagging and failing to adhere to the steel surface, leading to hand fatigue. Therefore, to address the inconvenience of the aforementioned technology in removing rust from top steel components, we propose a pneumatic rust removal tool. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pneumatic slag removal and rust removal tool.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A pneumatic slag and rust removal tool includes a mounting shell. Rollers are mounted on both sides of the upper surface of the mounting shell, and magnetic rings are installed inside the rollers. A mounting seat is provided inside the mounting shell. A flow cavity is provided inside the lower side of the mounting seat. Several ventilation holes are provided on the upper side of the mounting seat corresponding to the flow cavity. A rotating shaft is rotatably installed in the ventilation holes. A fan blade is provided in the middle of the rotating shaft corresponding to the ventilation hole. The upper end of the rotating shaft extends to the top of the mounting seat and is equipped with several brush strips. A connecting pipe is connected to the lower side wall of the mounting seat corresponding to the flow cavity. An air extraction component is provided at the end of the connecting pipe away from the mounting seat.
[0007] Preferably, the air extraction assembly includes an air extractor and a filter, the filter being installed on the body of the connecting pipe, and the end of the connecting pipe furthest from the mounting base being connected to the air extractor.
[0008] Preferably, airbags are installed at both ends of the bottom surface of the mounting housing, and the lower surface of the mounting base is connected to the upper surface of the airbags.
[0009] Preferably, the upper surface edge of the mounting base is provided with an upwardly protruding collection frame, and the upper surface of the lifting frame is equipped with ball bearings.
[0010] Preferably, the bottom surface of the flow cavity protrudes upward at both ends, and the inner surface of the flow cavity is a smooth surface.
[0011] Preferably, the rotating shaft is connected to the mounting base via a bracket, and the brush strip is connected to the rotating shaft via bolts.
[0012] Preferably, each end of the mounting shell is provided with a pair of tension brackets, and the inner bottom surface of the mounting shell is provided with a through-hole corresponding to the connecting pipe.
[0013] The pneumatic slag and rust removal tool proposed in this utility model has the following advantages:
[0014] 1. In this invention, the air extraction component forces air through the ventilation holes, pushing the internal blades. These blades, via a rotating shaft, drive the brush strips to rotate. The rotating brush strips then clean rust from the steel surfaces they contact. By using the air extraction component to provide power, the parts requiring manual operation do not need heavy components like motors, thus reducing the strain on the operator's hands. Simultaneously, the mounting shell can be magnetically attached to external steel surfaces using magnetic rings. This allows the mounting shell and all internal components to maintain contact with the steel surface without manual effort, making the device more user-friendly. The operator only needs to push or pull the mounting shell to move it, without having to exert extra force to support the device against the steel part. This effectively saves manpower. Furthermore, since the mounting shell and the steel part are in contact through rollers, the mounting shell still has good mobility. Therefore, compared with the traditional solution, this solution only requires the operator to provide horizontal force to move the device, which effectively reduces the manpower required and alleviates the soreness of the operator's hands. Even if the operator works for a long time, the absence of heavy components such as motors in the mounting shell further reduces the overall weight of the device, thereby further reducing the manpower required.
[0015] 2. The airbag in this invention allows the mounting base to move vertically to a certain extent, enabling the airbag to push the mounting base upwards, thus pushing it to fit against the surface of the steel component on the outside. This allows the brush strip to have a good fit with the surface of the steel component, facilitating the cleaning of rust from the brush strip's surface. The lifting frame facilitates the collection of rust residue brushed off to a certain extent. The ball bearings create a gap between the lifting frame and the steel component surface, allowing outside air to enter the ventilation hole through this gap. Furthermore, the friction between the lifting frame and the steel component changes from sliding friction to rolling friction, effectively reducing the resistance during the movement of the lifting frame (mounting base) and saving manpower. Because the bottom ends of the flow cavity bulge upwards, rust residue entering the flow cavity can move more smoothly towards the connecting pipe, facilitating its outflow through the connecting pipe.

[0025] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0026] Example 1
[0027] Reference Figure 1-4A pneumatic slag and rust removal tool includes a mounting shell 1. Rollers 2 are mounted on both sides of the upper surface of the mounting shell 1. Magnetic rings 3 are installed inside the rollers 2. A mounting seat 4 is provided inside the mounting shell 1. A flow cavity 5 is provided inside the lower side of the mounting seat 4. Several ventilation holes are provided on the upper side of the mounting seat 4 corresponding to the flow cavity 5. A rotating shaft 6 is rotatably installed inside the ventilation holes. A fan blade 7 is provided in the middle of the rotating shaft 6 corresponding to the ventilation holes. The upper end of the rotating shaft 6 extends to the top of the mounting seat 4 and is equipped with several brush strips 8. A connecting pipe 9 is connected to the lower side wall of the mounting seat 4 corresponding to the flow cavity 5. An air extraction component is provided at the end of the connecting pipe 9 away from the mounting seat 4.
[0028] Example 2
[0029] Reference Figure 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:
[0030] The air extraction assembly includes an air extractor 10 and a filter 11. The filter 11 is installed on the body of the connecting pipe 9. The end of the connecting pipe 9 away from the mounting base 4 is connected to the air extractor 10. The air extraction assembly allows fresh air from the outside to be drawn into the circulation chamber 5 through the ventilation hole under negative pressure, and then into the air extractor 10 through the connecting pipe 9. During this process, the filter 11 filters and collects rust and debris mixed in with the air. Airbags 12 are installed at both ends of the bottom surface of the mounting housing 1. The lower surface of the mounting base 4 is connected to the upper surface of the airbags 12. The airbags 12 allow the mounting base 2 to move vertically to a certain extent, thereby allowing the airbags 12 to push the mounting base 4 upwards. The mounting base 4 is pushed to fit against the surface of the steel part on the top of the exterior, so that the brush strip 8 can have a good fit with the surface of the steel part on the top of the exterior, which makes it easier to clean the rust on the surface of the steel part of the brush strip 8. The upper edge of the mounting base 4 is provided with an upwardly protruding collection frame, and the upper surface of the lifting frame is equipped with ball bearings 13. The lifting frame is designed to collect the rust residue brushed off to a certain extent, while the ball bearings 13 are designed to create a certain gap between the lifting frame and the surface of the steel part, so that outside air can enter the ventilation hole through this gap. On the other hand, it changes the sliding friction between the lifting frame and the external steel part to rolling friction, which effectively reduces the resistance when the lifting frame, i.e., the mounting base 4, moves, thus saving manpower.
[0031] The bottom surface of the flow cavity 5 protrudes upwards at both ends, and the inner surface of the flow cavity 5 is a smooth surface. Because the bottom surface of the flow cavity 5 protrudes upwards at both ends, the rust residue entering the flow cavity 5 can move more smoothly to the connecting pipe 9, thus facilitating its flow out along the connecting pipe 9. The rotating shaft 6 is connected to the mounting base 4 through a bracket, and the brush strip 8 is connected to the rotating shaft 6 through bolts. The bracket facilitates the installation of the rotating shaft 6, while the detachable brush strip 8 facilitates the replacement and maintenance of the brush strip 8. Each end of the mounting shell 1 is provided with a pair of pull brackets, and the bottom surface of the mounting shell 1 is provided with a through-hole corresponding to the connecting pipe 9. The pull brackets facilitate the movement and force application of the mounting shell 1 by personnel, while the through-hole facilitates the insertion of the connecting pipe 9.
[0032] Operating principle and advantages: During use, the air extraction component generates suction, allowing outside air to enter the circulation chamber 5 of the mounting base 4 through the ventilation hole, and then be extracted through the connecting pipe 9. During this process, the air flowing through the ventilation hole pushes the blades 7 inside, thereby causing the blades 7 to drive the brush strips 8 to rotate through the rotating shaft 6. The rotating brush strips 8 can then clean rust from the surface of the steel parts in contact with it. By providing power through the air extraction component, the parts of the device that need to be operated by hand do not need to have heavy components such as motors, thus reducing the stress on the hands of the operator to a certain extent.
[0033] Meanwhile, during the above process, since the mounting shell 1 is equipped with rollers 2 and the rollers 2 are equipped with magnetic rings 3, the mounting shell 1 can be attracted to the surface of the external magnetic steel part through the magnetic rings 3. At this time, the mounting shell 1 and the various components installed inside it can maintain the connection with the steel part without the need for manual force. Thus, the personnel only need to push or pull the mounting shell 1 to move it. Their hands do not need to exert additional force to support the device and fit it against the steel part, which effectively saves manpower. Furthermore, since the mounting shell 1 and the steel part are in contact through the rollers 2, the mounting shell 1 can still have good mobility.
[0034] It should be further explained that the exhaust assembly allows fresh air from the outside to be drawn into the circulation chamber 5 through the ventilation hole under negative pressure, and then into the exhaust pump 10 through the connecting pipe 9. During this process, the filter 11 filters and collects rust and debris mixed in with the air. The airbag 12 allows the mounting base 2 to move vertically to a certain extent, which allows the airbag 12 to push the mounting base 4 upward, that is, to push the mounting base 4 to fit against the surface of the steel part on the outside. This allows the brush strip 8 to have a good fit with the surface of the steel part on the outside, thus facilitating the cleaning of rust on the surface of the steel part of the brush strip 8. The lifting frame facilitates the collection of rust and debris brushed off to a certain extent, while the roller... The setting of bead 13, on the one hand, creates a certain gap between the lifting frame and the surface of the steel part, so that outside air can enter the ventilation hole through this gap. On the other hand, it changes the sliding friction between the lifting frame and the outside steel part into rolling friction, thereby effectively reducing the resistance when the lifting frame, i.e. the mounting base 4, moves, thus saving manpower. Since the bottom ends of the flow cavity 5 protrude upward, the rust residue entering the flow cavity 5 can move more smoothly to the connecting pipe 9, so as to facilitate the flow out along the connecting pipe 9. The setting of the holding frame makes it easy for personnel to move and apply force to the mounting shell 1, and the convenience of personnel movement device can be further improved by connecting the traction rope to the holding frame. The setting of the through hole facilitates the installation of the connecting pipe 9.
[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
