Spraying cleaning abrasive particles of different sizes sequentially can enhance the rust removal effect on the steel surface. Most structural designs incorporate two parallel cleaning structures along the steel conveying path. The steel moves to different positions and the surface is cleaned sequentially. The above structures require two sets of cleaning auxiliary devices, which increases the size of the equipment and reduces the efficiency of rust removal. Utility Model Content

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0022] To improve the efficiency and effectiveness of steel processing, some steel materials need to have their surface rust and oxide removed before cutting.

[0023] High-pressure gas is used to spray cleaning sand onto the steel surface to effectively remove rust. Compared with chemical or high-pressure water gun rust removal, no water stains remain on the steel surface after rust removal, and no separate drying treatment is required afterward.

[0024] To enhance the rust removal effect of cleaning abrasive, some designs spray cleaning abrasive particles of different sizes sequentially to clean the steel surface. Spraying cleaning abrasive particles of different sizes sequentially can enhance the rust removal effect on the steel surface. Most structural designs incorporate two parallel cleaning structures along the steel conveying path. The steel moves to different positions and the surface is cleaned sequentially. The above structures require two sets of cleaning auxiliary devices, which increases the size of the equipment and reduces the efficiency of rust removal.

[0025] To solve the above problems, please refer to the appendix. Figure 1 -Appendix Figure 4 A continuous rust removal device for the surface of a large-scale semi-autogenous grinding mill liner includes a cutting body 100, a feeding body 200, and a closed rust removal device 400 installed between the cutting body 100 and the feeding body 200. The closed rust removal device 400 continuously removes rust from the surface of the cut workpiece 300.

[0026] The aforementioned workpiece 300 is an extra-large semi-autogenous grinding mill liner with a large length span.

[0027] Specifically, the enclosed rust removal device 400 includes an air blowing assembly 420 located above and a collection tank 410 located below. The air blowing assembly 420 continuously sprays cleaning sand towards the collection tank 410 to complete the continuous rust removal of the surface of the cut workpiece 300. The collection tank 410 can collect the sprayed cleaning sand in a concentrated manner to prevent the cleaning sand from spilling everywhere. A negative pressure structure can be installed in the collection tank 410 to enhance the concentrated collection effect of airflow and cleaning sand.

[0028] The air blowing assembly 420 here includes a relatively fixed first air nozzle 422 and a second air nozzle 423, which are located on the same arc-shaped connecting line. The first air nozzle 422 sprays out cleaning sand one, and the second air nozzle 423 sprays out cleaning sand two. The air blowing assembly 420 also includes a first drive shaft 421 for controlling the deflection of the first air nozzle 422 and the second air nozzle 423. The first drive shaft 421 is connected to an external electrical control device, which can control the first air nozzle 422 and the second air nozzle 423 to rotate synchronously. The first air nozzle 422 and the second air nozzle 423 are controlled to face the cutting workpiece 300 in turn, so as to complete two rust removal processes on the surface of the cutting workpiece 300, thereby improving the effect and efficiency of rust removal.

[0029] A cleaning auxiliary device 600 is also installed at the upper end of the collection tank 410. The cleaning auxiliary device 600 controls the cutting workpiece 300 to be raised to a predetermined height and rotated directionally around a predetermined axis. The cleaning auxiliary device 600 can control the directional rotation of the cutting workpiece 300, and can continuously clean the rust on the circumferential surface of the cutting workpiece 300 during the directional rotation process.

[0030] The collection tank 410 and the air blowing component 420 are adapted to the length of the workpiece 300 and extend along the length of the workpiece 300. The sprayed cleaning sand can thoroughly clean the rust on the surface of the workpiece 300, ensuring the overall cleaning effect.

[0031] In summary, through the above structural design, only one set of cleaning auxiliary device 600 needs to be designed to be opposite to the first air nozzle 422 and the second air nozzle 423, so as to control the cutting workpiece 300 to complete two different rust removal and cleaning in the same position, which greatly improves the effect and efficiency of rust removal and cleaning. At the same time, the equipment occupies a small volume and the control process is simple and convenient.

[0032] A first negative pressure collection opening 412 and a second negative pressure collection opening 413 are provided at the bottom of the collection tank 410. A flow guide valve group 500 located between the first negative pressure collection opening 412 and the second negative pressure collection opening 413 is also installed inside the collection tank 410. The flow guide valve group 500 controls the first negative pressure collection opening 412 or the second negative pressure collection opening 413 to be in the open state.

[0033] By controlling the first negative pressure collection opening to be in the open state and the second negative pressure collection opening to be in the closed state through the flow guide valve group 500, it is possible to guide and collect cleaning sand particles of different sizes.

[0034] Through the above structural design, the first negative pressure collection opening 412 and the second negative pressure collection opening 413 can guide and collect cleaning sand of different sizes, avoiding the mixing of cleaning sand particles of different sizes and reducing the difficulty of subsequent screening and sorting.

[0035] Specifically, the flow guide valve assembly 500 includes a flow guide sealing plate 510 and a second drive shaft 520 for controlling the deflection of the flow guide sealing plate 510. The first negative pressure collection opening 412 and the second negative pressure collection opening 413 are located on the path of the deflection of the flow guide sealing plate 510. Controlling the flow guide sealing plate 510 to deflect to different angles can complete the opening and closing control of the first negative pressure collection opening 412 and the second negative pressure collection opening 413.

[0036] The first negative pressure collection opening 412 and the second negative pressure collection opening 413 are located on the same horizontal plane, and both are located on the rotation path of the flow guiding sealing plate 510, controlling the flow guiding sealing plate 510 to be in a position of... Figure 4 When tilted as shown, the first negative pressure collection opening 412 can be controlled to be in a conducting state and the second negative pressure collection opening 413 to be in a closed state, thereby realizing the automatic guidance of the cleaning sand.

[0037] With the above structural design, there is no need to design separate valves in the first negative pressure collection opening 412 and the second negative pressure collection opening 413. The conduction control can be completed by controlling a set of flow guiding sealing plates 510 to tilt in different directions. This is simple and convenient, and greatly improves the effect and efficiency of conduction control.

[0038] Furthermore, the inclined guide sealing plate 510 can guide the falling cleaning sand, accelerating its entry into the corresponding negative pressure collection opening for centralized collection, thus preventing cleaning sand of different sizes from mixing in the collection tank 410.

[0039] It should be noted that the bottom of the collection tank 410 can be designed to be arc-shaped to fit the rotating flow guide sealing plate 510, or flexible buffer pads or elastic airbags can be installed on both sides of the flow guide sealing plate 510 so that it can abut against the inner wall of the collection tank 410 after the flow guide sealing plate 510 rotates to its limit position, thereby enhancing the sealing performance of the overall structure.

[0040] Air blowing openings 414 are installed at the upper ends of the first negative pressure collection opening 412 and the second negative pressure collection opening 413. Both air blowing openings 414 are inclined inward, and gas can be blown outward through the air blowing openings 414, which can accelerate the flow of cleaning sand on the surface of the guide sealing plate 510 and speed up the discharge time.

[0041] The air blowing opening 414 here can be designed with a separate valve to control the opening and closing of the air blowing opening 414. This valve can be controlled in conjunction with the flow guide valve group 500, which reduces the difficulty of control.

[0042] Inside the collection tank 410, a guide block 411 is also installed. The guide block 411 is located at the lower end of the cleaning auxiliary device 600. The upper surface of the guide block 411 is also inclined inward, which can guide the cleaning sand and realize the concentrated collection of cleaning sand on both sides in the length direction.

[0043] The cleaning aid 600 and the guide block 411 here can be designed in multiple sets to enhance the load-bearing capacity of the large-mass cutting workpiece 300.

[0044] The feeding body 200 includes inclined guide rails 210, with at least two sets of guide rails 210. The cleaning auxiliary device 600 is located on the yarn tube extending from the guide rails 210. The cutting workpiece 300 can roll along the guide rails 210 to the side of the cleaning auxiliary device 600. The cleaning auxiliary device 600 lifts the cutting workpiece 300 at a predetermined position and controls the directional rotation of the cutting workpiece 300. At the same time, a retractable locking protrusion can be installed on the upper end of the guide rails 210. The locking protrusion can intercept the cutting workpiece 300 and reduce the impact of the cutting workpiece 300 on the cleaning auxiliary device 600.

[0045] The cleaning auxiliary device 600 includes a rotary drive assembly 620 for controlling the rotation of the cutting workpiece 300 around a predetermined axis and a lifting assembly 610 for controlling the lifting and lowering of the cutting workpiece 300. The lifting assembly 610 can be selected as multiple sets of hydraulic telescopic rods, and the rotary drive assembly 620 can be selected as two sets of spaced electric rollers, so as to realize the lifting and rotation control of the cutting workpiece 300.

[0046] For ball mill liners with opposite sides, columnar clamping devices can be installed on both sides to clamp the ball mill liner and control it to rotate around a predetermined axis, thus completing continuous surface rust removal during continuous rotation.

[0047] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
