Description

Technical Field

[0001] The present invention relates to the technical field of steel ring processing, and particularly relates to an anti-adhesion device for both sides of a steel ring. Background Art

[0002] When manufacturing a steel ring, the two sides of the steel ring are prone to adhesion due to heating. The adhered steel rings need to spend extra time and manpower for separation at the construction site, increasing the construction cost and reducing the construction progress. If a large number of steel rings are adhered, workers need to process them one by one, which will seriously delay the subsequent processes such as steel bar binding. Forcibly separating the adhered steel rings may cause damage such as scratches and deformations on the surface of the steel bars, reducing the mechanical properties of the steel bars and affecting the safety of the entire building structure. Scratches may become the stress concentration sites of the steel bars during use, accelerating the corrosion and fatigue failure of the steel bars. Summary of the Invention

[0004] Further, two groups of evenly arranged driving rollers are provided at the middle position of the main body, and the two groups of driving rollers are arranged in a Z shape up and down, and the rotational speed of the top driving roller is faster than that of the bottom driving roller. The two groups of driving rollers form a dropping section, and two groups of oppositely arranged temperature sensors are provided at the middle position between the two groups of driving rollers; the cooling component includes: cooling nozzles, cooling pipes, and a cooling fan; the two groups of cooling nozzles are rotatably connected inside the main body, and the cooling nozzles are connected to the cooling fan through the cooling pipes; the spraying component includes: spraying nozzles, spraying pipes, a spraying pump, and a storage tank; the spraying nozzles are provided on one side of the cooling nozzles, and the spraying nozzles are connected to the spraying pump through the spraying pipes; the storage tank stores a separating agent.

[0005] Further, the relationship between the cooling air volume q of the cooling nozzles in the cooling component, the total air volume Q of the cooling fan total and the number m of the nozzles is and the flow velocity u of the cooling air in the pipe satisfies the formula where A is the cross-sectional area of the pipe.

[0006] Further, the spraying pressure P and flow rate Q of the spraying pump are adjusted by the control system according to the formulas P = P0 + k1×(T - T0) + k2×(v - v0) and Q = Q0 + k3×(T - T0) + k4×(v - v0), where P0 and Q0 are the initial pressure and flow rate, T is the temperature of the steel bar coil, T0 is the reference temperature, v is the transmission speed of the steel bar coil, v0 is the reference speed, and k1 - k4 are adjustment coefficients; the rotation speed N of the cooling fan is adjusted by the control system according to the temperature T feedback by the temperature sensor, following the PID adjustment formula where N0 is the initial rotation speed, e(t) = T - T set is the temperature deviation, T set is the set temperature, K p 、K i 、K d are the PID parameters; when the transmission speed v of the steel bar coil and the temperature T satisfy v > v max and T > T max , the spraying pressure P of the release agent spraying assembly increases according to the formula , and the flow rate Q increases according to the formula ; when v < v min and T < T min , the spraying pressure P decreases according to the formula , and the flow rate Q decreases according to the formula , v max 、v min 、T max 、T min are the set speed and temperature extreme values.

[0007] Further, the working steps of the anti - adhesion device on both sides of the steel bar coil are as follows:

[0008] The temperature T of the steel bar coil is monitored in real - time by the temperature sensors installed at the entrance of the steel bar coil falling section and near the anti - adhesion device. When T > T set , according to the control signal generation formula S = K×(T - T set ), where S is the control signal intensity and K is the signal intensity coefficient; start the cooling fan and the spraying assembly;

[0009] The control system adjusts the rotation speed of the cooling fan according to the temperature signal feedback by the temperature sensor, according to the formula , where u(t) is the control output and \(e(t)\) is the temperature deviation;

[0010] According to the transmission speed v and temperature T of the steel bar coil, adjust the spraying pressure and flow rate of the spraying pump according to the formulas P = P0 + k1×(T - T0) + k2×(v - v0) and Q = Q0 + k3×(T - T0) + k4×(v - v0);

[0011] When the steel bar coil starts to be transported, according to the transport speed v and the set time interval Δt for spraying the release agent, the spraying length of the release agent on the surface of the steel bar coil is determined by the formula L = v×Δt to ensure uniform coverage.

[0012] Further, the temperature sensor converts the temperature signal into an electrical signal V and transmits it to the control system. The conversion formula is V = V0 + α×(T - T0), where V0 is the reference voltage and α is the temperature-voltage conversion coefficient.

[0013] Further, in the cooling air control step, when the control system adjusts the rotation speed of the cooling fan according to the PID algorithm, the integral term I int has an accumulation formula of I int (t) = I int (t - Δt) + K i ×e(t)×Δt, and the differential term D diff has a calculation formula of

[0017] Beneficial effects

[0018] The cooling air nozzle is rotatably connected to the inside of the main body, and the angle and direction of the cooling air can be adjusted according to actual needs to ensure better cooling effect on the steel bar coil. The spraying nozzle is arranged on one side of the cooling air nozzle, so that the cooling and spraying operations can be closely coordinated to improve the overall anti-adhesion effect.

[0019] By clarifying the relationship between the cooling air volume of the cooling air nozzle, the total air volume of the cooling fan and the number of nozzles, as well as the flow velocity formula of the cooling air in the pipeline, the accurate control of the cooling air volume and flow velocity can be achieved, ensuring the stability and reliability of the cooling effect.

[0020] The rotation speed of the cooling fan is PID-regulated by the control system according to the temperature feedback by the temperature sensor, and the cooling intensity can be adjusted in real time according to the actual temperature of the steel bar coil, making it easier to control the temperature of the steel bar coil within a suitable range and preventing adhesion problems caused by too high temperature.

[0021] The spraying pressure and flow rate of the spraying pump are adjusted by the control system according to factors such as the temperature of the steel bar coil and the transmission speed through a specific formula, and the spraying amount can be automatically adjusted according to the actual situation of the steel bar coil, avoiding the waste of the release agent while ensuring the anti-adhesion effect.

[0022] When the transmission speed and temperature of the steel bar coil change, there are corresponding dynamic adjustment formulas for the spraying pressure and flow rate, further improving the adaptability and accuracy of spraying, so that the spraying of the release agent can better adapt to different production conditions.

[0023] By installing temperature sensors at the entrance of the steel bar coil falling section and near the anti-adhesion device to monitor the temperature of the steel bar coil in real time, and performing operations such as starting and adjusting the cooling fan and spraying components according to the temperature signal, the whole process of the anti-adhesion process of the steel bar coil is monitored and accurately controlled in real time.

[0024] Based on the transmission speed of the steel bar coil and the set spraying time interval of the release agent, the spraying length of the release agent on the surface of the steel bar coil is determined, which can ensure that the release agent evenly covers the surface of the steel bar coil and effectively improve the anti-adhesion effect.

[0025] When the temperature sensor fails, there is a backup temperature estimation formula to estimate the temperature, maintain the operation of the equipment, avoid production interruption caused by sensor failure, and ensure the continuity and stability of production.

[0026] When the cooling fan overloads and stops, it can stop the working of the release agent spraying component according to the corresponding formula and start the backup cooling fan, preventing the abnormal temperature of the steel bar coil due to the failure of the cooling fan, and at the same time avoiding the waste of resources and possible quality problems caused by continuous spraying without cooling.

[0027] When the spraying pump is blocked, start the cleaning program according to the cleaning pressure formula, which can timely solve the problem of the blocked spraying pump, ensure the normal operation of the equipment, and reduce the impact of equipment failures on production.

[0028] The formula for the thickness of the isolation layer formed by the release agent on the surface of the steel bar coil, the spraying flow rate, the transmission speed of the steel bar coil, and the spraying time is given, which helps to accurately adjust parameters such as the spraying flow rate, the transmission speed, and the spraying time according to the required thickness of the isolation layer during actual operation, and achieve precise control of the quality of the isolation layer.

[0081] Summary of experimental data on the anti - adhesion device on both sides of the steel bar ring

[0082] Cooling fan speed regulation: In Experiment 1, for different temperatures of the steel bar ring, the speed of the cooling fan was regulated through the PID regulation mechanism. When the temperature of the steel bar ring was higher than the set temperature, for example, when the temperature was 750 °C, the set temperature was 120 °C, the temperature deviation was 630 °C, and the initial speed was 1000 rpm. With the PID parameter settings of a proportional coefficient of 0.5, an integral coefficient of 0.1, and a derivative coefficient of 0.2, the adjusted speed reached 1100 rpm; when the temperature was 700 °C and the deviation was 600 °C, the adjusted speed was 1050 rpm. This shows that the cooling fan can effectively adjust its speed according to the temperature deviation to achieve the cooling of the steel bar ring.

[0083] Adjustment of Spray Pump Parameters: Experiment 2 demonstrated the adjustment of spray pump parameters under different steel ring transmission speeds and temperatures. Taking the initial pressure of 0.3 MPa, the initial flow rate of 5 L / min, and the adjustment coefficient of 0.2 as an example, when the transmission speed was 0.5 m / s and the temperature was 750 °C, the spray pressure was adjusted to 0.32 MPa and the flow rate was adjusted to 5.2 L / min. When the transmission speed and temperature changed, the spray pump parameters changed accordingly, reflecting the adaptability to different working conditions.

[0084] Fault Handling:

[0085] Temperature Sensor Failure: Experiment 3 showed that when the temperature sensor failed, the temperature could be estimated through the backup temperature estimation method to maintain the operation of the equipment.

[0086] Cooling Fan Overload Shutdown: Experiment 4 showed that when the cooling fan overloaded and shut down, the spray stop pressure could be calculated according to a specific method. For example, when the current spray pressure was 0.35 MPa, the current fan speed was 800 rpm, and the rated speed was 1000 rpm, the spray stop pressure was 0.28 MPa to ensure the safety of the equipment.

[0087] Spray Pump Blockage: Experiment 5 showed that when the spray pump was blocked, the cleaning pressure could be calculated according to the cleaning pressure calculation method. For example, when the coefficient was 1.5 and the pressure difference before and after blockage was 0.1 MPa, the cleaning pressure was 0.15 MPa, and then the cleaning procedure was started.

[0088] Release Agent Isolation Layer Thickness: Experiment 6 gave the isolation layer thickness formed by the release agent on the surface of the steel ring under different spray flow rates, transmission speeds, and spray times. For example, when the spray flow rate was 6 L / min, the transmission speed was 0.5 m / s, the spray time was 10 s, and the total area to be sprayed on both sides of the steel ring was 2 \(m^2\), the isolation layer thickness was 0.05 mm. These data helped to understand the relationship between the spraying effect of the release agent and various parameters.

[0089] Specific usage method and function of this embodiment: In the present invention, when the steel bar coil passes by, the temperature sensors 4 at the entrance of the steel bar coil dropping section and near the device continuously monitor the temperature of the steel bar coil. When the temperature reaches the set condition, a control signal whose strength is determined by the correlation coefficient is generated according to the control signal generation rule. Then, the cooling fan 202 and the spraying component are started. After that, the temperature sensor 4 feeds back the temperature signal to the control system. The control system adjusts the rotation speed of the cooling fan 202 according to the temperature deviation, the initial rotation speed, and the set PID parameters according to the PID adjustment algorithm. The cooling fan 202 changes the cooling air volume of the cooling air nozzle 2 through the cooling pipeline 201 to cool the steel bar coil. At the same time, the control system adjusts the spraying pressure and flow rate of the spraying pump 302 according to the transmission speed and temperature of the steel bar coil, in combination with the reference speed, the reference temperature, and the adjustment coefficient according to the corresponding formula, so that the release agent is evenly sprayed on the surface of the steel bar coil from the storage tank 303 through the spraying pump 302 and the spraying pipeline 301 by the spraying nozzle 3. When the transmission speed and temperature of the steel bar coil meet specific conditions, the spraying pressure and flow rate increase according to the corresponding formula; if they do not meet the conditions, they decrease. When the steel bar coil starts to be transmitted, the spraying length is determined according to the transmission speed and the set release agent spraying time interval according to the relevant formula. During this period, the temperature sensor 4 converts the temperature signal into an electrical signal according to a specific formula involving the reference voltage and the temperature-voltage conversion coefficient and transmits it to the control system. The control system comprehensively adjusts the rotation speed of the cooling fan 202 and the parameters of the spraying pump 302 based on this. When the temperature sensor 4 fails, the control system estimates the temperature using the standby temperature estimation formula with the relevant data before the failure to maintain the operation of the equipment. When the cooling fan 202 overloads and stops, the control system calculates the stop spraying pressure according to the corresponding formula based on the current spraying pressure, the fan rotation speed, and the rated rotation speed, stops the operation of the release agent spraying component, and then starts the standby cooling fan 202. When the spraying pump 302 is blocked, the control system calculates the cleaning pressure according to the cleaning pressure formula based on the coefficient and the pressure difference before and after the blockage and starts the cleaning program. Finally, the release agent forms a release layer on the surface of the steel bar coil according to a specific formula related to the spraying flow rate, the transmission speed, and the spraying time and involving the total spraying area required on both sides of the steel bar coil. The processed steel bar coil moves through the driving roller 101.
