Description

Technical Field

[0001] This invention relates to the field of electric power and power engineering technology, and specifically to an automatic cleaning and water replenishment system for rolling mills. Background Technology

[0002] The emulsion used in the lubrication system of a hot finishing mill is a mixture of concentrate, additives, and water, with water comprising over 90% of it. During rolling, due to the composition of this emulsion, it easily mixes with metal powder to form sludge, which adheres to the inside of the mill. This sludge may drip onto the sheet metal during rolling, affecting its surface quality. Furthermore, the long-term accumulation of sludge makes the inside of the mill extremely slippery and produces a strong odor, hindering maintenance personnel from entering the mill to address the problem.

[0003] As production progresses, the emulsion loses moisture, requiring the replenishment of deionized water. Both the replenishment and cleaning processes require manual operation, which is outdated and inefficient.

[0004] Currently, cleaning and water replenishment of hot finishing mills are mostly carried out separately. The emulsion tank is directly replenished quantitatively through an automatic water replenishment system, and specific parts are cleaned using some nozzles.

[0005] Existing technologies use centralized water replenishment, adding several tons of deionized water at once. Although the moisture content of the emulsion fluctuates within the standard range, it still has a certain impact on the stability of the product. Summary of the Invention

[0006] In view of this, the present invention provides an automatic cleaning and water replenishment system for rolling mills, which automatically replenishes deionized water to the emulsion during the rolling mill production process, thereby improving the stability of the emulsion inside the rolling mill and improving product quality.

[0011] A first branch line is connected to the main pipeline and the first nozzle above the front smoke hood of the rolling mill. The first nozzle is equipped with a first valve for cleaning the area where the front smoke hood of the rolling mill is located.

[0012] A second branch line is connected to the main pipeline and the second nozzle above the mill rear fume hood. The second nozzle is equipped with a second valve for cleaning the area where the mill rear fume hood is located.

[0013] The controller, connected to the first valve, the second valve, and the water replenishment calculation module, calculates the spraying duration of the first and second nozzles based on the water replenishment calculation module, combined with historical water replenishment data and the water volume to be sprayed by the first and second nozzles, and controls the state of the first and second valves to achieve cleaning of the inside of the rolling mill.

[0014] The first valve and the second valve are solenoid valves.

[0015] It also includes a valve status detection sensor connected to the first valve and the second valve, used to detect and output the valve status of the first valve and the second valve.

[0016] It also includes a valve status controller connected to the first valve and the second valve, used to control the status of the first valve and the second valve.

[0017] It also includes a first flow meter installed on the first branch and a second flow meter installed on the second branch, used to count the water consumption entering the front smoke hood and the rear smoke hood of the rolling mill.

[0018] It also includes a display for the valve status detection sensor, the first flow meter, and the second flow meter, for displaying the operating data of the valve status detection sensor, the first flow meter, and the second flow meter.

[0019] It also includes a communication unit connected to the first flow meter and the second flow meter, used to transmit the operating data of the first flow meter and the second flow meter.

[0020] The communication unit includes at least one of a wireless communication module and a wired communication module, wherein the wireless communication module is any one of a 5G module, a 4G module, and an infrared communication module.

[0021] The first nozzle and the second nozzle are 360° rotating nozzles.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of one embodiment of the automatic cleaning and water replenishment system for rolling mills provided in this invention.

[0030] One specific embodiment of the present invention provides an automatic cleaning and water replenishment system for rolling mills, comprising:

[0031] Deionized water tank 10 storing deionized water;

[0032] Main pipeline 20 connected to the deionized water tank 10;

[0033] A first branch line 30 is connected to the main pipeline 20 and the first nozzle 31 above the mill front fume hood 50. The first nozzle 31 is equipped with a first valve 32 for cleaning the area where the mill front fume hood 50 is located.

[0034] The second branch line 40 is connected to the main pipeline 20 and the second nozzle 41 above the mill rear fume hood 60. The second nozzle 41 is equipped with a second valve 42 for cleaning the area where the mill rear fume hood 60 is located.

[0035] The controller, connected to the first valve 32, the second valve 42, and the water replenishment calculation module, calculates the water spraying duration of the first nozzle 31 and the second nozzle 41 based on the water replenishment calculation module, historical water replenishment data, and the water volume to be sprayed by the first nozzle 31 and the second nozzle 41, and controls the state of the first valve 32 and the second valve 42 to achieve cleaning of the inside of the rolling mill.

[0036] The automatic cleaning and water replenishment system for the rolling mill includes a deionized water tank 10 storing deionized water; a main pipeline 20 connected to the deionized water tank 10; a first branch pipeline 30 connected to the main pipeline 20 and a first nozzle 31 above the front fume hood 50 of the rolling mill, the first nozzle 31 being equipped with a first valve 32 for cleaning the area where the front fume hood 50 of the rolling mill is located; and a second branch pipeline 40 connected to the main pipeline 20 and a second nozzle 41 above the rear fume hood 60 of the rolling mill, the second nozzle 41 being equipped with a second valve 42 for cleaning the rear fume hood of the rolling mill. The area in section 60 is cleaned. A controller connected to the first valve 32, the second valve 42, and the historical water replenishment data storage device calculates the spraying duration of the first nozzle 31 and the second nozzle 41 based on the water replenishment calculation module, historical water replenishment data, and the required water volume of the first nozzle 31 and the second nozzle 41. This controls the state of the first valve 32 and the second valve 42, achieving internal cleaning of the rolling mill and replenishment of the emulsion with deionized water, improving the cleanliness of the rolling mill and the stability of the emulsion. By adopting a combined approach, the original cleaning and water replenishment processes are integrated, achieving process integration. The structure is simple, easy to implement and maintain, utilizes the original structure with minimal modifications, and has strong reversibility and low modification costs. It has a wide range of applications and broad practical value.

[0037] The controller in this application uses water volume calculated based on previously collected water replenishment data (which could be a statistical table of each replenishment or other water replenishment statistics). After analysis and matching with the sprinkler heads, the controller controls the valve opening and closing based on time. The controller (such as a PLC controller) controls the valve to open for a certain period of time (obtained through calculation), and then the sprinkler heads spray water. The flow meter can detect the specific amount of water sprayed, and technicians can use the flow meter data to verify and revise the calculated water volume.

[0038] This application does not limit the type, size, etc. of the first valve 32 and the second valve 42. Generally, the appropriate type is selected according to different needs. In one embodiment, the first valve 32 and the second valve 42 are solenoid valves.

[0039] To further improve management efficiency, in one embodiment, the automatic cleaning and water replenishment system for the rolling mill also includes valve status detection sensors for the first valve 32 and the second valve 42, for detecting and outputting the valve status of the first valve 32 and the second valve 42.

[0040] The valve status detection sensor automatically detects and outputs the valve status of the first valve 32 and the second valve 42. By comparing the status with the current execution command, it can be determined whether the current equipment is operating normally, thus improving management efficiency.

[0041] This application does not limit the structure of the valve status detection sensor; it can be implemented using a switching circuit or a photoelectric signal, etc.

[0042] To enable remote control, in one embodiment, the automatic cleaning and water replenishment system for the rolling mill further includes a valve status controller connected to the first valve 32 and the second valve 42, for controlling the status of the first valve 32 and the second valve 42.

[0043] By providing a valve status controller, the status of the first valve 32 and the second valve 42 can be remotely controlled, achieving centralized control and improving control efficiency.

[0044] This application does not limit the structure of the valve status controller, including but not limited to the use of relays.

[0045] To further achieve precise control over the flow rate of deionized water at various locations, in one embodiment, the automatic cleaning and water replenishment system for the rolling mill also includes a first flow meter 33 installed in the first branch 30 and a second flow meter 43 installed in the second branch 40, for counting the water consumption entering the front fume hood 50 and the rear fume hood 60 of the rolling mill.

[0046] By setting the first flow meter 33 and the second flow meter 43, precise control of water consumption at various locations can be achieved, improving the effectiveness of deionized water usage.

[0047] This application does not limit the type or structure of the first flow meter 33 and the second flow meter 43.

[0048] Furthermore, to improve management efficiency, in one embodiment, the automatic cleaning and water replenishment system for the rolling mill also includes a display for the valve status detection sensor, the first flow meter 33, and the second flow meter 43, for displaying the operating data of the valve status detection sensor, the first flow meter 33, and the second flow meter 43.

[0049] Furthermore, to facilitate data transmission, in one embodiment, the automatic cleaning and water replenishment system for the rolling mill also includes a wireless communication unit connected to the first flow meter 33 and the second flow meter 43, for transmitting the operating data of the first flow meter 33 and the second flow meter 43.

[0050] The wireless communication unit enables remote transmission of the operating data of the first flow meter 33 and the second flow meter 43, improving the flexibility of data transmission.

[0051] This application does not limit the type of wireless communication unit, which includes one of the following: 5G module, 4G module, and infrared communication module, or other types of wireless communication module.

[0052] This application does not limit the number or type of nozzles, and the first nozzle 31 and the second nozzle 41 are 360° rotating nozzles.

[0053] Different nozzles are used according to different needs, and the number of nozzles can also be designed as needed. Moreover, the flow rate can be achieved through water pressure.

[0054] This application does not limit the type of the first branch 30 and the second branch 40, which can be flexible hoses or rigid pipes.

[0055] In one embodiment, the automatic cleaning and water replenishment system for the rolling mill mainly consists of a deionized water tank 10, pipelines, solenoid valves, and 360° rotating nozzles. Based on the existing cleaning and water replenishment system, a branch line is branched off from the inlet pipeline of the deionized water tank 10. This branch line is controlled by a manual ball valve, and then splits into two branches leading to the front and rear fume hoods of the rolling mill, respectively. Each branch is controlled by a solenoid valve and then connected to the nozzles below the fume hoods via flexible hoses. To ensure complete cleaning coverage inside the rolling mill, the nozzles are 360° rotating nozzles commonly used in tank cleaning systems.

[0056] Based on the existing water replenishment data, the amount of water loss in the emulsion after each coil is estimated by the hot finishing mill. Combined with the cleaning time after each coil is produced, the required nozzle flow rate is obtained. Finally, a suitable 360° rotating nozzle is selected based on relevant data.

[0057] Work process: After the hot finishing mill finishes producing a coil, the production staff presses a button, the electromagnetic gate valve opens, and deionized water drives the 360° rotating nozzle to rotate and spray out to clean the inside of the mill. The cleaning water mixes with the emulsion and flows back to the emulsion tank through the drain to complete the water replenishment. When the cleaning reaches the set time, the electromagnetic gate valve closes, and the cleaning and water replenishment ends.

[0058] This application may use only the aforementioned automatic mill cleaning and water replenishment system for fully automatic cleaning, eliminating the original manual cleaning pipelines, or it may retain the original cleaning and water replenishment pipelines for manual cleaning during shutdown and for large-scale water replenishment, serving as a backup to improve the reliability of cleaning. Alternatively, the automatic mill cleaning and water replenishment system of this application may be added directly to the existing manual cleaning pipeline technology. This application does not limit the choice of which method to use.

[0059] By employing 360° rotating nozzles and using deionized water, full-coverage cleaning of the rolling mill's interior was achieved. Furthermore, by using existing water replenishment data, the average water loss was estimated, and nozzles with appropriate flow rates were selected to achieve quantitative water replenishment.

[0060] The 360° rotating nozzle used in this application is to achieve full-coverage cleaning. By controlling fewer nozzles, a larger area can be cleaned, reducing control difficulty and increasing coverage.

[0061] Of course, if staff need to perform precision cleaning on certain key or specific areas, they can use nozzles with fixed positions to clean those areas specifically; this application does not impose any restrictions on this.

[0062] This application employs a combined approach, integrating the original cleaning and water replenishment processes to achieve process integration. The rolling mill is likened to a tank, and a 360° rotating nozzle, commonly used in tanks, is used to clean the interior of the rolling mill, achieving full coverage.

[0063] This application features a simple structure, facilitating implementation and maintenance. It utilizes existing structures with minimal modifications, exhibits strong reversibility, and has low modification costs. It has a wide range of applications and broad practical value for promotion.

[0064] In summary, the automatic cleaning and water replenishment system for rolling mills provided in this application includes a deionized water tank storing deionized water; a main pipeline connected to the deionized water tank; a first branch pipeline connected to the main pipeline and a first nozzle above the front fume hood of the rolling mill, the first nozzle being equipped with a first valve for cleaning the area where the front fume hood of the rolling mill is located; a second branch pipeline connected to the main pipeline and a second nozzle above the rear fume hood of the rolling mill, the second nozzle being equipped with a second valve for cleaning the area where the rear fume hood of the rolling mill is located; and a controller connected to the first valve, the second valve, and a historical water replenishment data storage device, which calculates the spraying duration of the first nozzle and the second nozzle based on the water replenishment calculation module combined with the historical water replenishment data and the water volume to be sprayed by the first nozzle and the second nozzle, and controls the state of the first valve and the second valve to achieve cleaning of the inside of the rolling mill and replenishment of deionized water to the emulsion, thereby improving the cleanliness of the inside of the rolling mill and the stability of the emulsion. By employing a combined approach, the original cleaning and water replenishment processes are integrated, achieving process consolidation. The structure is simple, easy to implement and maintain, utilizes the existing structure with minimal modifications, and possesses strong reversibility and low transformation costs. It has a wide range of applications and broad practical value for promotion.
