Description

Technical Field

[0001] This application relates to the technical field of steel bar surface rust removal devices, and particularly relates to a steel bar surface rust removal device. Background Art

[0002] Construction projects often stop due to various reasons such as tight funds and force majeure factors. During the shutdown period, some steel bars of the building are still not wrapped by concrete and are exposed to the air, thus coming into contact with water molecules in the air and causing rust. After resuming work, workers need to use wire brushes to remove rust from these rusty steel bars, but the manual brushing force is small, resulting in incomplete rust removal.

[0003] In the prior art, generally, other tools such as wire balls are used manually to grind and brush the steel bars. This method has a high labor intensity for operators, low operation efficiency, and it is difficult to guarantee the quality of rust removal. In some cases, chemical methods can also be used for rust removal, such as using hydrochloric acid for rust removal. Although this method is simple, it pollutes the environment and has a high cost. And the existing mechanical grinding rust removal devices often have a large weight of the grinding device, and can only be fixed in position for grinding during use, unable to move and unable to adapt to steel bars of various diameter sizes. The technical personnel in this field provide a steel bar surface rust removal device to solve the problems raised in the above background art. Utility Model Content

[0004] In order to solve the problems raised in the above background art, this application provides a steel bar surface rust removal device.

[0005] The steel bar surface rust removal device provided by this application adopts the following technical solutions:

[0006] A steel bar surface rust removal device includes a rust removal box. A fuel storage tank is fixedly installed near one side at the upper end of the rust removal box. An oil inlet pipe is connected to the upper end of the fuel storage tank. The lower end of the fuel storage tank penetrates into the interior of the rust removal box and is connected to a drip pipe. And a circular ring one is fixedly installed inside the rust removal box. A wet sponge is attached to the inner wall of the circular ring one. And the lower end of the drip pipe is in contact with the wet sponge. A PLC controller is fixedly installed on one side of the fuel storage tank.

[0007] Preferably, U-shaped seats are fixedly installed at the front and rear ends of the rust removal box. And a driving rod is movably installed inside the U-shaped seats. Two limiting rollers are symmetrically and fixedly installed on the outer part of the driving rod. The driving rod is powered by electricity.

[0008] Preferably, two electric push rods penetrate through both sides of the rust removal box. And a fixing plate is fixedly installed at one end of the electric push rod inside the rust removal box.

[0009] Preferably, three rotating rollers are movably installed horizontally and equidistantly at the upper end of the fixing plate, and a number of rust removal brushes are fixedly installed on the outer part of the rotating rollers. The rotating rollers are powered by a rotating motor.

[0010] Preferably, a second ring is fixedly installed between the fixing plate and the first ring inside the rust removal box. A driving ring is movably installed inside the second ring, and abrasive paper sheets are symmetrically and fixedly installed on the outer part of the driving ring.

[0011] In summary, the present application includes the following beneficial technical effects: Through the provided oil storage tank, the oil inside the oil storage tank is soaked into the wet sponge inside the first ring through the drip pipe. The rust-removed steel bar passes through the wet sponge, thereby applying oil to the surface of the steel bar, isolating the water vapor in the air in a short time, preventing the steel bar from rusting again, and improving the rust removal efficiency.

[0012] Through the second ring, the rust-removed steel bar first passes through the two abrasive paper sheets, and the driving ring drives the two abrasive paper sheets to rotate, thereby rubbing the surface of the steel bar again and cleaning the small debris remaining on the surface of the steel bar after rust removal, making the rust removal efficiency higher.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0019] Such as Figures 1 - 4As shown in the figure, a device for removing rust from the surface of steel bars includes a rust removal box 1. One side of the upper end of the rust removal box 1 is fixedly installed with an oil storage tank 6. The upper end of the oil storage tank 6 is connected with an oil inlet pipe 7. The lower end of the oil storage tank 6 penetrates into the interior of the rust removal box 1 and is connected with a drip pipe 12. And a first ring 13 is fixedly installed inside the rust removal box 1. A wet sponge 14 is attached to the inner wall of the first ring 13. And the lower end of the drip pipe 12 is in contact with the wet sponge 14. A PLC controller 11 is fixedly installed on one side of the oil storage tank 6. First, place the steel bar to be rust-removed above the limiting roller 4 and then transfer it into the rust removal box 1. After the two electric push rods 5 position the fixing plate 8 in a suitable position, the rust removal brush 10 on the surface of the rotating roller 9 grinds and removes rust from the surface of the steel bar. Through the provided oil storage tank 6, the oil inside the oil storage tank 6 is soaked into the wet sponge 14 inside the first ring 13 through the drip pipe 12. The rust-removed steel bar penetrates through the wet sponge 14, thereby applying oil to the surface of the steel bar, isolating the water vapor in the air in a short time, preventing the steel bar from rusting again, and improving the rust removal efficiency.

[0024] The implementation principle of a rust removal device for the surface of steel bars in an embodiment of this application is as follows: First, place the steel bars to be rust-removed above the limiting rollers 4 and then convey them into the interior of the rust removal box 1. After the two electric push rods 5 position the fixed plate 8 in a suitable position, the rust removal brushes 10 on the surface of the rotating rollers 9 polish and remove rust from the surface of the steel bars. Through the provided oil storage tank 6, the oil inside the oil storage tank 6 is soaked into the wetting sponge 14 inside the first ring 13 through the drip pipe 12. The rust-removed steel bars pass through the wetting sponge 14, thereby applying oil to the surface of the steel bars, isolating the water vapor in the air in a short time, preventing the steel bars from rusting again, and improving the rust removal efficiency. The rust-removed steel bars first pass through two sandpaper sheets 17, and the driving ring 16 drives the two sandpaper sheets 17 to rotate, thereby rubbing the surface of the steel bars again and cleaning the small debris remaining on the surface of the steel bars after rust removal, making the rust removal efficiency higher.
