Description

Technical Field

[0001] The invention relates to the technical field of oxide scale cleaning equipment, in particular to an automatic pulse oxide scale blowing device for processing wear-resistant steel balls. Background Art

[0002] Wear-resistant steel balls are the key grinding media in ball mills, and their quality directly affects the efficiency and cost of mineral processing. The current mainstream manufacturing process is to roll heated round steel into shape through hot rolling.

[0003] During this high-temperature rolling process, a thick layer of iron oxide scale (oxidized iron scale) forms on the surface of the round steel. This scale breaks down and falls off under the rolling force. Traditionally, simple collection troughs or pits have been installed beneath the rolling mill, allowing it to be collected naturally by gravity. However, this approach has significant drawbacks. First, the high-speed splashing of scale spreads over a large area, making collection efficiency extremely low. Large amounts of scale are scattered around the equipment, creating a harsh working environment and making cleaning and maintenance difficult. Second, the accumulated scale can increase equipment wear and corrosion, posing a safety hazard. While some technologies utilize high-pressure gas purging or negative pressure adsorption, these often suffer from undirected purges, consume significant energy, and cause the scale to scatter, severely impacting the working environment.

[0021] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example: like Figure 1-6 As shown, an automatic pulse oxide scale blowing device for processing wear-resistant steel balls includes a processing table 2, a feeder 1 is provided on one side of the processing table 2, and the feeder 1 feeds round steel 99 into a rolling mill 3, and a rolling mill 3 for hot rolling round steel 99 into steel balls is provided on the processing table 2, and a lower pressing rod 42 is provided below the double spiral of the rolling mill 3, and a collection groove 6 for the passage of oxide scale is opened on both sides of the lower pressing rod 42, and a high-pressure air curtain guide device 5 is provided on the collection groove 6, and the high-pressure air curtain guide device 5 includes a guide surface 53 for guiding airflow, and the guide surface 53 is arranged at the upper end of the collection groove 6, and the upper end top of the guide surface 53 is fixedly connected with a guide fin 54 for blocking airflow, and a nozzle 52 for ejecting gas is provided above the double spiral of the rolling mill 3.

[0023] The feeder 1 (e.g., a set of servo-driven feed rollers) precisely feeds the round steel 99 into the rolling centerline of the rolling mill 3. The rolling mill 3 utilizes rollers with a double-helix structure, which are the key actuators for rolling the round steel 99 into a spherical shape. A lower pressure rod 42 is fixedly mounted directly below the double-helix rollers. Its function is to cooperate with the upper pressure rod 41 above to prevent the round steel 99 from bouncing up and down during the rolling process. On either side of the lower pressure rod 42, elongated collection troughs 6 are machined, through which most of the detached oxide scale falls. The guide surface 53 of the high-pressure air curtain guide device 5 is welded to the upper edge of the collection trough 6 and is shaped as an outward-sloping slope. A row of inclined guide fins 54 is welded to the highest point of the guide surface 53. Multiple nozzles 52 are mounted above the double-helix rollers of the rolling mill 3, and the gas they eject is directed toward the guide surface 53, which is tilted downward.

[0024] It should be noted that if Figure 6As shown in the figure, there is a flow direction of some gases. First, the high-pressure gas from the nozzle 52 can blow off the oxide scale on the surface of the high-temperature round steel 99, which plays a cleaning role and prevents excessive oxide scale from scratching the surface of the steel ball during rolling. The blown-off oxide scale slides into the collection tank 6 under the action of gravity and gas guidance. At the same time, when the gas is blown onto the guide surface 53, it will flow upward along the guide surface 53, and contact the lower end of the double-helix roller through the guidance of the guide fin 54. At this time, an air curtain is formed, so that the oxide scale will not escape from the gap between the double-helix roller and the processing table 2.

[0025] At the same time, it should also be noted that the guide fin 54 is inclined inward. When the airflow blows onto the double-helix roller, the oxide scale in the gap of the double-helix roller can be blown away to prevent the oxide scale adhering to the double-helix roller from affecting the subsequent rolling of the steel balls. At the same time, the guide fin 54 is inclined inward to make the blown oxide scale float inward, and then cooperate with the downward airflow to send the oxide scale into the collection tank 6.

[0026] Furthermore, it also includes a limiting component 4, which includes an upper clamping rod 41. The upper clamping rod 41 is driven by a cylinder to move up and down, and cooperates with the lower clamping rod 42 to limit the round steel 99 in the rolling mill 3; the limiting component 4 is an important component to ensure the stability of the rolling process. The upper clamping rod 41 is driven by a cylinder and can move up and down. When the round steel 99 is fed into the rolling mill 3, the cylinder drives the upper clamping rod 41 to press down, and together with the fixed lower clamping rod 42, a narrow channel is formed, which accurately limits the round steel 99 to the biting area of ​​the double spiral rollers of the rolling mill 3. This prevents the round steel 99 from deviating up and down due to the rolling force, ensures the roundness of the steel ball and the smoothness of the rolling process, and also provides a relatively fixed falling area for the oxide scale (i.e., the collection trough 6 on both sides).

[0027] Furthermore, the high-pressure air curtain guide device 5 also includes a compressor 51, which is connected to a nozzle 52 through an air duct. There are multiple nozzles 52, which are evenly distributed on the upper pressure rod 41. The nozzles 52 face the guide surface 53, and the angle α between the nozzle 52 and the side direction of the upper pressure rod 41 is 30°-60°. The power source of the high-pressure air curtain guide device 5 is a fixed air compressor 51. The high-pressure gas generated by the compressor 51 is transported to the multiple nozzles 52 evenly distributed on the upper pressure rod 41 through the air duct laid on the equipment. These nozzles 52 are not vertically downward, but their central axes form an angle α between 30° and 60° (preferably 45°) with the side direction of the upper pressure rod 41. This makes the direction of the ejected air flow obliquely point to the guide surface 53 downward.

[0028] Furthermore, a blanking assembly 8 is provided at the rear end of the rolling mill 3. This blanking assembly 8 includes a blanking port 81, which is located on the processing table 2. A guide channel 82 for guiding the steel balls is located below the blanking port 81, which is provided on the processing table 2 at the rear end of the rolling mill 3. After exiting the rolling mill 3, the formed, incandescent steel balls fall directly through this blanking port 81. Below this blanking port 81, an inclined guide channel 82 (typically made of heat-resistant steel plate) is welded to the bottom. The incandescent steel balls slide along this channel to subsequent quenching or conveying equipment, completing the blanking process after rolling.

[0029] Furthermore, a negative pressure suction device 9 is provided below the collection trough 6 to assist in collecting oxide scale. This device comprises a negative pressure chamber 91, fixedly connected to the lower end of the collection trough 6. A draft fan 92, separated by an isolation net, is located on one side of the collection trough 6. A collection chamber 94 for collecting oxide scale is fixedly connected to the lower end of the negative pressure chamber 91. An electric discharge valve 95 is located at the lower end of the collection chamber 94. Below the electric discharge valve 95, a transport vehicle 96 for transporting oxide scale is located. This transport vehicle 96 is slidably connected to tracks 98 via an electric runner 97. The oxide scale initially collected by the collection trough 6 continues to fall. Directly below the collection trough 6 is the negative pressure suction device 9. The core of this device is a negative pressure chamber 91. One side of the negative pressure chamber 91 is connected to the suction port of the draft fan 92 via an isolation net (not shown). This isolation net prevents oxide scale from being drawn into the fan impeller, providing protection. The bottom of negative pressure chamber 91 is connected to a collection chamber 94 for storing collected oxide scale. An electric discharge valve 95 is installed at the bottom outlet of collection chamber 94. When a certain amount of oxide scale accumulates in collection chamber 94, the control unit 100 commands the electric discharge valve 95 to open, unloading the oxide scale into a transport cart 96 located directly below. This transport cart 96 is moved on tracks 98 by electric carriages 97, enabling automated loading and transport, significantly reducing the labor intensity of manual cleaning.

[0030] Furthermore, a high-temperature linear laser array sensor 7 is fixedly connected to one end of the collection tank 6 to detect the presence of oxide scale. A control unit 100 is fixedly connected to the processing table 2 and is in communication with the high-temperature linear laser array sensor 7, the induced draft fan 92, and the electrically controlled proportional valve in the nozzle 52 pipeline. The high-temperature linear laser array sensor 7 monitors in real time whether the laser is obstructed by oxide scale. The control unit 100 is configured to generate a feedback control signal based on the actual oxide scale obstruction signal fed back by the high-temperature linear laser array sensor 7, compare it with a preset threshold signal, and dynamically fine-tune the rotation speed of the induced draft fan 92 and the electrically controlled proportional valve in the nozzle 52 pipeline, thereby achieving closed-loop control.

[0031] When a large amount of scale falls off, the laser is frequently and extensively obstructed. The sensor feeds this signal back to the control unit 100. The control unit 100 compares this signal with an internally preset threshold (for example, the upper limit of the number of obstructions per unit time). If the actual value far exceeds the threshold, indicating a large amount of scale shedding, the control unit 100 generates a feedback control signal: it increases the speed of the induced draft fan 92 to enhance suction and increases the opening of the electronically controlled proportional valve to increase the strength and sweeping force of the air curtain. Conversely, when scale shedding decreases, the system automatically reduces power and enters energy-saving operation mode. This achieves closed-loop control that automatically adjusts to actual operating conditions.

[0032] Furthermore, two sets of high-temperature linear laser array sensors 7 are provided, one on each side. The control unit 100 is configured to compare the actual scale obstruction signals fed back by the high-temperature linear laser array sensors 7 on both sides. If the difference between the two sets of signals exceeds a preset threshold, the control unit 100 transmits a nozzle 52 blockage signal to an external terminal. The presence of two symmetrical sets of high-temperature linear laser array sensors 7 allows the control unit 100 to perform more advanced diagnostic functions. Under normal operating conditions, the amount of scale shed from the rollers on both sides should be roughly equal, so the signal strength and frequency fed back by the sensors on both sides should also be similar. The control unit 100 continuously compares the two sets of signals. If the signal on one side is consistently significantly weaker than the other (the difference exceeds a preset threshold, such as 30%), it is highly likely that the nozzle 52 on that side is partially blocked, causing the air curtain's guidance function to fail and preventing the scale from being effectively blown into the sensor's monitoring area. In this case, the control unit 100 does not immediately adjust the equipment parameters. Instead, it generates a "nozzle 52 blocked" alarm signal and transmits this signal to the host computer in the central control room or the operator's mobile phone terminal, prompting maintenance inspection. This enables a predictive maintenance function based on data comparison.

[0033] Furthermore, the control unit 100 is configured to calculate the scale shedding load based on existing rolling process parameters and generate a feedforward control signal accordingly, preemptively adjusting the speed of the induced draft fan 92 and the air supply pressure of the electronically controlled proportional valve in the nozzle 52 pipeline. The control unit 100 stores a mathematical model based on process knowledge (for example, larger steel balls require greater rolling force, resulting in greater scale shedding). When the system prepares to roll large 100mm Φ steel balls, the control unit 100 obtains the process parameters of "high rolling force, low speed" from the main control system of the rolling mill 3. Based on the model, it predicts that a large amount of scale will be generated. Therefore, it issues a feedforward control signal in advance: before the scale is shed and before the sensor detects a signal, the speed of the induced draft fan 92 is increased to a higher preset value and the opening of the electronically controlled proportional valve is increased. This way, by the time a large amount of scale actually begins to shed, the collection system is already operating at optimal power and in a "ready" state, achieving seamless integration and optimal control. It constitutes an intelligent system with rapid response, precise control and optimal energy consumption.

[0034] The workflow is as follows: The feeder 1 delivers the heated round steel 99 to the rolling center line of the rolling mill 3. The upper clamping rod 41 of the limit assembly 4 works together with the lower clamping rod 42 under the drive of the cylinder to radially constrain the round steel 99 to ensure the stability of the rolling process.

[0035] The twin-helical rollers of rolling mill 3 begin rolling round steel 99 into shape. During this process, the oxide scale on the surface of round steel 99 falls off due to plastic deformation. Control unit 100 acquires rolling process parameters in real time, uses a built-in algorithm to predict the amount of oxide scale generated, and outputs a feedforward control signal to the electronically controlled proportional valves in the induced draft fan 92 and nozzle 52 pipelines, pre-adjusting system operating parameters.

[0036] The nozzles 52 of the high-pressure air curtain guide device 5 are distributed along the upper compression rod 41, with their spray direction forming an angle of 30°-60° with the vertical. The airflow provided by the compressor 51 forms a directional air curtain, directing the detached oxide scale toward the collection trough 6. The guide surface 53 and guide fins 54 work together to ensure that the oxide scale is concentrated and enters the inlet of the collection trough 6.

[0037] The scale passes through the collection trough 6 and enters the negative pressure suction device 9. An induced draft fan 92 generates a negative pressure field within the negative pressure chamber 91, transporting the scale to the collection chamber 94. When the material in the collection chamber 94 reaches the set capacity, the control unit 100 activates the electric discharge valve 95, unloading the scale into the transport vehicle 96. The electric vehicle 97 automatically transports the material along the track 98.

[0038] High-temperature linear laser array sensor 7 monitors the flow of oxide scale at the inlet of collection tank 6 in real time and transmits the detection signal to control unit 100. Control unit 100 implements closed-loop regulation of induced draft fan 92 speed and nozzle pressure 52 based on the difference between the feedback signal and a preset threshold. The system also diagnoses and issues an alarm for nozzle blockage 52 by comparing the symmetry of the signals from high-temperature linear laser array sensors 7 on both sides.

[0039] The steel balls that have completed rolling and scale removal are transported to the subsequent process through the discharge port 81 and the guide channel 82. The entire system achieves a dynamic balance between efficient scale removal and energy consumption through the combination of feedforward control and feedback regulation.
