Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A residual anode charging system 100 according to an embodiment of the present invention is described below with reference to fig. 1-5.

As shown in fig. 1, the anode scrap feeding system 100 according to the embodiment of the present invention includes a vertical frame 1, a horizontal frame 2, a lifting frame 3 suitable for placing an anode scrap stack, a light curtain sensor for detecting whether the anode scrap stack is completely pushed into the vertical frame 1, a lifting frame position detection module for detecting whether the lifting frame 3 is moved in place, a first winch 4, a pulley, a frequency converter, a shaping device 5, a horizontal pushing device 6 for pushing the anode scrap stack on the lifting frame 3 into a metallurgical furnace, a rope pulling encoder, a remote control transmitter and a controller.

Specifically, the vertical frame 1 has an inlet 11 for a residual anode stack. The horizontal frame 2 is arranged at the upper part of the vertical frame 1. The lifting frame 3 is movably arranged in the vertical frame 1 between a loading position 31, a shaping position 32 and a discharge position 33, and the lifting frame 3 at the loading position 31 is opposite to the anode scrap pile inlet 11. The light curtain sensor is installed at the anode scrap stack inlet 11 of the vertical frame 1.

The first winch 4 comprises a winding drum on which the rope is at least partially wound and a rope, the pulley is arranged on the vertical frame 1, one end of the rope passes through the pulley to be connected with the hoisting frame 3 so as to drive the hoisting frame 3 to move between the loading position 31, the shaping position 32 and the unloading position 33, and the frequency converter is connected with a driving motor of the first winch 4. The vertical direction is indicated by an arrow B in fig. 1.

The shaping device 5 is arranged on the vertical frame 1. The horizontal pushing device 6 is arranged on the horizontal frame 2. The pulling rope of the pulling rope encoder is attached to the pusher 62 of the horizontal pushing device 6 to detect the displacement of the pusher 62. The controller is connected with the light curtain sensor, the lifting frame position detection module, the frequency converter, the driving motor, the shaping device 5, the horizontal pushing device 6, the pull rope encoder and the remote control transmitter.

Because the vertical lifting height drop of the lifting frame 3 is large, workers in the related art cannot observe the operation condition of the equipment conveniently when operating the original control box, an upper control box and a lower control box need to be arranged on site, and the two workers are matched to complete the operation, so that the labor is wasted. In addition, workers operating the upper control box are in a severe working environment due to the fact that the workers are close to the furnace mouth.

The utility model also provides an utilize according to the utility model discloses the anode scrap feeding method that the anode scrap feeding system 100 implemented. According to the utility model discloses anode scrap charging method includes following step:

and (3) conveying the residual anode stack to a lifting frame 3, detecting whether the residual anode stack is completely pushed into the vertical rack 1 by using a light curtain sensor, and if so, sending a starting signal by using a remote control transmitter.

After receiving the starting signal transmitted by the remote control transmitter, the controller controls the operation of the frequency converter and the driving motor of the first winch 4 so as to move the lifting frame 3 located at the loading position 31 to the shaping position 32. Through the removal of converter and driving motor control hoisting frame 3, can conveniently control hoisting frame 3 fast migration and the slow speed through the frequency control that changes the converter and remove, control is convenient.

The hoisting frame 3 stays at the shaping position 32 and the controller controls the shaping device to operate so as to shape the anode scrap stack on the hoisting frame 3 with the shaping device 5. Through carrying out the plastic to the anode scrap buttress, can make the relative rule of placeeing position of anode scrap buttress, the anode scrap buttress of being convenient for is pushed the metallurgical furnace smoothly.

The controller again controls the operation of the inverter and the driving motor of the first hoist 4 so as to move the lifting frame 3 located at the shaping position 32 to the discharging position 33.

The controller controls the operation of the horizontal pushing device 6 so that the anode scrap stack on the lifting frame 3 staying at the discharging position 33 is pushed into the metallurgical furnace by means of the horizontal pushing device 6.

Adopt light curtain sensor to detect whether the anode scrap buttress is pushed in vertical frame 1 completely, when fork truck placed the anode scrap buttress on hoisting frame 3 promptly, light curtain sensor can detect the anode scrap buttress position to detect whether the anode scrap buttress is put in place by fork truck. The position of the anode scrap stack is detected through the light curtain sensor, workers do not need to get off to observe whether the anode scrap stack is placed in place by a forklift or not in a short distance, whether a starting key is pressed or not can be determined according to signals of the light curtain sensor, and time is saved. If the anode scrap stack is not completely pushed into the vertical rack 1, the anode scrap stack is not put in place, and the light curtain sensor can send out a field alarm signal. When the forklift worker observes that the light curtain sensor has an alarm signal, the forklift worker can operate the forklift to continue to move the residual anode stack without getting off the vehicle until the residual anode stack is put in place and then the start key is pressed, so that the processing time can be saved, and the production efficiency is improved.

Because the remote control emitter and the light curtain sensor are arranged, a forklift worker can conveniently press the start key of the remote control emitter after observing that the light curtain sensor has no alarm signal. In other words, a forklift can remotely operate the anode scrap charging system 100 through the remote control transmitter, thereby saving labor and keeping field personnel away from a harsh working environment (a working environment close to the fire hole). Meanwhile, the remote controller also has the functions of pause and reset, when an operator finds an emergency, the operator can press a pause key, the anode scrap feeding process is paused at the moment, and the feeding process can be continued by pressing the pause key after the emergency is relieved; and the equipment can be automatically restored to the initial state by pressing a reset key. The safety and reliability of the system are effectively improved.

Meanwhile, the light curtain sensor is also connected with the controller, the controller can control the frequency converter and the driving motor to work according to signals of the light curtain sensor, and when the light curtain sensor sends out an alarm signal, the residual anode charging system 100 cannot be started even if a forklift operator mistakenly presses a starting key of the remote control transmitter. Therefore, the situation that the anode scrap stacks collide with the vertical rack 1 when the lifting frame 3 is lifted due to the fact that the anode scrap stacks are not completely pushed into the vertical rack 1 can be prevented, and the safety and reliability of the anode scrap feeding system 100 are improved.

In addition, the pulling-up encoder can accurately position the displacement position of the pushing head 62 of the horizontal pushing device 6, and when the pushing head 62 extends out, the pulling rope is driven to be pulled out from the body of the pulling-up encoder so as to detect the horizontal displacement signal of the furnace throwing device and ensure that the pushing head 62 accurately throws materials according to the set position, so that the working reliability of the anode scrap feeding system 100 can be improved.

Therefore, according to the utility model discloses anode scrap charging system 100 and anode scrap charging method have that production efficiency is high, use manpower sparingly, make the workman keep away from advantages such as adverse work environment, fail safe nature height.

As shown in fig. 1 to 5, the anode scrap feeding system 100 includes a vertical frame 1, a horizontal frame 2, a lifting frame 3 adapted to place an anode scrap stack, a light curtain sensor for detecting whether the anode scrap stack is completely pushed into the vertical frame 1, a lifting frame position detecting module for detecting whether the lifting frame 3 is moved in place, a first hoist 4, a frequency converter, a shaping device 5, a horizontal pushing device 6 for pushing the anode scrap stack on the lifting frame 3 into the metallurgical furnace, a rope pulling encoder, a remote control transmitter and a controller.

Furthermore, according to the utility model discloses anode scrap charging system 100 still includes hydraulic pressure part and switch board. The hydraulic part comprises an oil station, an oil pump and an oil pipe. The hydraulic part is used for providing power for the shaping device 5 and the horizontal pushing device 6. The power distribution cabinet distributes power for field devices such as an oil station, an oil pump, a first winch, a second winch and a third winch.

As shown in fig. 1, the vertical stand 1 has an inlet 11 for a residual anode stack. The lifting frame 3 is movably arranged in the vertical frame 1 between a loading position 31, a shaping position 32 and a discharge position 33, and the lifting frame 3 at the loading position 31 is opposite to the anode scrap pile inlet 11. The light curtain sensor is installed at the anode scrap stack inlet 11 of the vertical frame 1. The first hoist 4 is connected to the hoisting frame 3 so as to drive the hoisting frame 3 to move between a loading position 31, a shaping position 32 and a discharge position 33, and the frequency converter is connected to a drive motor of the first hoist 4.

The controller is connected with the light curtain sensor, the lifting frame position detection module, the frequency converter, the driving motor and the remote control transmitter.

A worker operates a forklift to place the packed anode scrap stack on the lifting frame 3, and presses a start key of the remote control transmitter after observing that the light curtain sensor has no alarm signal. After the controller receives a starting signal transmitted by the remote control transmitter, the controller firstly starts self-checking according to an internal program, and if the state of the anode scrap feeding system 100 meets the starting requirement (the state of a hydraulic part and a frequency converter is normal, an oil pump is opened, and other parts are all in an initial state), the controller controls the lifting frame 3 to rapidly ascend so that the lifting frame 3 can reach the shaping position 32.

It should be noted that the remote control transmitter is held by a field worker and has functions of starting, suspending, resetting and the like. The staff can reset, pause the operation to the system according to the condition in the material feeding process: and (3) pressing a reset button, stopping the feeding action of the system at once, sequentially returning all the components to the initial state, and finally returning the whole system to the initial state before feeding. The first time the pause button is pressed, the system immediately stops the feeding action. And pressing the pause button again, and resuming the feeding action by the system.

As shown in fig. 4, the poppet position detecting module includes an incremental encoder, a first poppet limit switch for detecting that the poppet 3 reaches the loading position 31, a second poppet limit switch for detecting that the poppet 3 reaches the shaping position 32, and a third poppet limit switch for detecting that the poppet 3 reaches the discharging position 33. An incremental encoder is mounted on the drive motor and is used to detect the vertical displacement of the lifting frame 3. Each of the first hoisting frame limit switch, the second hoisting frame limit switch and the third hoisting frame limit switch is arranged on the vertical frame 1.

The first hoisting frame limit switch is located below the residual anode stack inlet 11 and is spaced from the residual anode stack inlet 11 by a preset distance, and when the hoisting frame 3 moves to the material loading position 31, the first hoisting frame limit switch can be triggered. The second lifting frame limit switch and the shaping device 5 are located at the same level, and the second lifting frame limit switch is triggered when the lifting frame 3 is moved to the shaping position 32. The third hoisting frame limit switch and the horizontal pushing device 6 are located at the same level, and the third hoisting frame limit switch is triggered when the hoisting frame 3 is moved to the discharge position 33.

The feeding process of the anode scrap stack comprises the horizontal action of the shaping device 5, the horizontal action of the horizontal pushing and conveying device 6 and the horizontal movement of the anode scrap stack. In order to prevent the shaping device 5 and the horizontal pushing device 6 from colliding with the lifting frame 3 when they move horizontally and the anode scrap stack from colliding with the horizontal machine frame 2 when they move horizontally, the anode scrap feeding system 100 has high requirements for the accuracy of alignment of the lifting frame 3 at the loading position 31, the shaping position 32, and the unloading position 33.

The incremental encoder is used as a part of the lifting frame position detection module, so that the detection precision is greatly improved, and the safety of system operation can be improved. Meanwhile, the controller can set a speed reduction point in a program according to the use condition at will in the debugging process of the equipment, and compared with a mode of adopting a limit switch as a speed reduction point, the method is more flexible and convenient, and the incremental encoder is more reliable and durable.

Since the position detection of the hoisting frame 3 may cause a malfunction of the system in case of a problem. Therefore, when the incremental encoder is arranged, a first lifting frame limit switch, a second lifting frame limit switch and a third lifting frame limit switch are also arranged. The following description will take the first hoisting frame limit switch as an example to illustrate the effects of the first hoisting frame limit switch, the second hoisting frame limit switch and the third hoisting frame limit switch: during operation of the system, for example when the lifting frame 3 is moved from the shaping position 32 to the loading position 31, the controller detects the real-time position of the lifting frame 3 by means of the incremental encoder and reduces the speed of the lifting frame 3 to a lower speed at a preset deceleration point position, reducing the inertia of the movement of the apparatus. After the lifting frame 3 collides with the first lifting frame limit switch at a low speed, the controller stops outputting an operation signal to the frequency converter, and simultaneously outputs a brake signal, so that the lifting frame 3 starts braking, and the lifting frame 3 finally and accurately falls on the material loading position 31. The safety and reliability of the system operation are improved.
