Technical Field

[0001] This invention relates to the technical field of automatic identification and processing methods for viscous iron concentrate silos, specifically to an automatic identification and processing method for viscous iron concentrate silos. Background Technology

[0002] During the production process, it is necessary for on-site personnel to observe and identify the phenomenon. The phenomenon cannot be automatically identified. When the on-site operator discovers the phenomenon, the usual methods are to manually poke the hopper or manually activate the air cannon to eliminate it. This method is dangerous, inefficient, and ineffective. In addition, it is also delayed and cannot eliminate the phenomenon in time, which affects the stability of product quality. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an automatic identification and handling method for viscous iron concentrate silos, solving the problems of high risk and poor effectiveness in existing methods.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic identification and processing method for viscous iron concentrate silos, comprising a hopper, an annular air duct fixedly installed inside the top side wall of the hopper, several high-pressure nozzles installed at the bottom of the annular air duct, the annular air duct passing through the side wall of the hopper and connected to an air duct, the other end of the air duct being connected to a high-pressure blower, a feed inlet provided inside the top of the hopper, a discharge outlet provided inside the bottom of the hopper, a support fixedly installed on the inner wall of the center of the hopper, several stirring steel bars fixedly installed at the bottom of the support, a vibration device provided on the outer wall of the hopper located at the support, and a buffer pad fixedly installed on the contact surface between the vibration device and the hopper.

[0005] Preferably, a fixed shaft seat is installed on one side of the outer wall of the hopper and below the vibration device. A bushing is movably installed on the fixed shaft seat. A counterweight plate is fixedly installed on the bushing. A detection plate is installed at the bottom end of the counterweight plate. A sensor is installed on the bottom outer wall of the hopper and on one side of the fixed shaft seat. A contact switch is installed at the detection end of the sensor.

[0006] Preferably, a conveyor belt is provided at the bottom of the discharge port, and side plates are fixedly installed on both sides of the conveyor belt, and a baffle is fixedly installed at one end of the conveyor belt located at the discharge port.

[0007] Preferably, the vibration device, the high-pressure fan, the sensor, and the detection plate are all wired to a controller.

[0008] Preferably, when the counterweight plate is in a naturally drooping state under the action of gravity, there is a certain gap between the detection plate and the upper surface of the conveyor belt, and the counterweight plate will contact the contact switch and press the contact switch into the sensor.

[0009] Preferably, it includes the following steps:

[0010] S1: Under normal conditions, the counterweight plate is tilted in the direction of material movement, the bottom of the detection plate is in contact with the material, the sensor is in the open state, the vibration device is not started, and the high-pressure blower is not started.

[0011] S2: When the hopper is in a sump-like state, the counterweight plate is in a natural downward state under the action of gravity. The counterweight plate presses the contact switch into the sensor, and the sensor is in a closed state. At the same time, the bottom of the detection plate is not in contact with the material. The sensor and the detection plate will transmit an electrical signal to the controller. The controller will start the vibration device and the high-pressure blower.

[0017] The following will refer to the appendices in the embodiments of the present invention. Figure 1-2 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a technical solution comprising a hopper 21, wherein an annular air duct 4 is fixedly installed inside the top side wall of the hopper 21, and several high-pressure nozzles 5 are installed at the bottom of the annular air duct 4. The annular air duct 4 passes through the side wall of the hopper 21 and is connected to an air duct 3. The other end of the air duct 3 is connected to a high-pressure blower 1. A feed inlet 6 is provided inside the top of the hopper 21, and a discharge outlet 10 is provided inside the bottom of the hopper 21. A support 8 is fixedly installed on the inner wall of the center of the hopper 21, and several stirring steel bars 20 are fixedly installed at the bottom of the support 8. A vibration device 7 is provided on the outer wall of the hopper 21 located at the support 8, and a buffer pad 9 is fixedly installed on the contact surface between the vibration device 7 and the hopper 21.

[0019] A fixed bearing seat 17 is installed on one side of the outer wall of the hopper 21 and below the vibration device 7. A bushing 16 is movably installed on the fixed bearing seat 17. A counterweight plate 15 is fixedly installed on the bushing 16. A detection plate 19 is installed at the bottom end of the counterweight plate 15. A sensor 14 is installed on the bottom outer wall of the hopper 21 and on one side of the fixed bearing seat 17. A contact switch 18 is installed at the detection end of the sensor 14.

[0020] The bottom of the discharge port 10 is provided with a conveyor belt 11, and side plates 13 are fixedly installed on both sides of the conveyor belt 11. A baffle 12 is fixedly installed at one end of the conveyor belt 11 located at the discharge port 10.

[0021] The vibration device 7, the high-pressure fan 1, the sensor 14, and the detection plate 19 are all wired to the controller 2.

[0022] When the counterweight plate 15 is in a naturally drooping state under the action of gravity, there is a certain gap between the detection plate 19 and the upper surface of the conveyor belt 11, and the counterweight plate 15 will contact the contact switch 18 and press the contact switch 18 into the sensor 14.

[0023] Includes the following steps:

[0024] S1: Under normal conditions, the hopper has the counterweight plate 15 tilted in the direction of material movement, the bottom of the detection plate 19 in contact with the material, the sensor 14 in the open state, the vibration device 7 not started, and the high-pressure blower 1 not started.

[0025] S2: When the hopper is in a slumped state, the counterweight plate 15 is in a natural downward state under the action of gravity. The counterweight plate 15 presses the contact switch 18 into the sensor 14, and the sensor 14 is in a closed state. At the same time, the bottom of the detection plate 19 is not in contact with the material. The sensor 14 and the detection plate 19 will transmit electrical signals to the controller 2. The controller 2 will start the vibration device 7 and the high-pressure blower 1. The vibration device 7 vibrates the hopper 21, and the support 8 and the stirring steel bar 20 in the hopper 21 vibrate together to stir and vibrate the material in the hopper 21, eliminating the slumping phenomenon. The high-pressure blower 1 sprays high-pressure air through the air duct 3, the annular air pipe 4 and the high-pressure nozzle 5 to clean the material adhering to the inner wall of the hopper 21 and generate pressure to push the material downward.

[0026] Those skilled in the art will be able to use the procedures in this case, and the specific connections and operating sequence should refer to the following working principle. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process.

[0027] Example: When slack formation occurs, material accumulates at the discharge port, interrupting the material flow on the conveyor belt. The counterweight plate 15 hangs freely under gravity, pressing the contact switch 18 on the sensor 14 inward. Upon receiving pressure from the counterweight plate 15, the sensor 14 transmits an electrical signal to the controller 2. The controller 2 then starts the high-pressure blower 1 and the vibration device 7. The high-pressure blower 1 compresses air, which then passes through the air duct 3 and the annular air pipe 4 before being ejected from the high-pressure nozzle 5. The high-pressure airflow ejected from the high-pressure nozzle 5 will... Pressure is generated on the surface of the material inside the hopper 21, pushing the material downward and cleaning the material remaining or adhering to the inner wall of the hopper 21. After the vibration device 7 is started, it will vibrate the entire hopper 21. The vibration of the hopper 21 will also cause the support 8 and the stirring steel bar 20 inside the hopper 21 to vibrate. Since the bottom end of the stirring steel bar 20 is unrestrained, the vibration force generated by the support 8 is transmitted to the bottom end of the stirring steel bar 20, making the movement amplitude of the bottom end of the stirring steel bar 20 greater, and vibrating the material inside and outside the hopper 21 at the same time, preventing the material from sticking and clumping together, and eliminating the clogging phenomenon.

[0028] After the clogging phenomenon occurs, the detection end of the detection plate 19 cannot contact the material, and it will also send an electrical signal to the controller 2 to start the high-pressure blower 1 and the vibration device 7 to eliminate the clogging phenomenon.

[0029] Once the material silo problem is eliminated, the material is discharged normally from the outlet. The material on the conveyor belt pushes the counterweight plate 15 in the direction of material movement, causing the contact switch 18 to pop out. After the sensor 14 no longer senses the pressure from the contact switch 18, it stops outputting electrical signals to the controller 2. After the detection plate 19 comes into contact with the material, it also stops outputting electrical signals to the controller 2. The controller 2 then shuts down the vibration device 7 and the high-pressure blower 1, allowing the device to discharge material normally.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
