Description

Technical Field

[0001] The present application relates to the field of aluminum rod processing, and in particular to a continuous automatic feeding mechanism and feeding method for a melting furnace. Background Art

[0002] The processing process of aluminum rods in factories usually involves melting qualified aluminum ingots at high temperature (about 900 degrees) in a melting furnace, then letting them stand in a standing furnace for a certain period of time, and then draining the molten aluminum through a launder to a casting machine for cooling and forming. The formed aluminum is then rolled into aluminum rod products of corresponding specifications through a rolling mill.

[0003] There are generally two types of factory melting furnaces. One is a vertical furnace, which mainly consists of a chimney, a vertical furnace, a melting furnace, a base, a loader, and a combustion device. The other is a horizontal furnace, which mainly consists of a flue, a smoke (dust) hood, a base, a combustion device, and a furnace body.

[0004] Comparing the two types of furnaces, we found that the vertical furnace's feed port is located above the furnace. A loading mechanism lifts the material to the top port, where it enters the melting furnace in a free-falling motion caused by its own weight. This trajectory is not a straight free-fall, but rather a parabolic free-fall. The entire stack of aluminum ingots is prone to scattering and colliding during its fall, easily causing them to strike the furnace wall, damaging it. This leads to frequent vertical furnace failures and increased maintenance costs. Furthermore, the top feed port remains open for extended periods, resulting in significant energy losses and, as a result, has been abandoned by aluminum foundries. Vertical melting furnaces have been gradually replaced by horizontal melting furnaces.

[0005] The process from melting to rolling out aluminum rod products is basically mechanized and automated, but the process of feeding aluminum ingots (aluminum regrind) into the melting furnace is relatively primitive, arduous, dangerous, and has high energy loss. There are two types of feeding in production:

[0006] A. Feeding before ignition

[0007] B. Feeding in continuous production process

[0008] The first feeding method is relatively simple. Although there are certain problems, since it is an operation in a static state before production, the risk is relatively small and the energy loss is also small.

[0009] 1. The feeding method and process in the current continuous production process:

[0010] The melting furnace door is 2.4m long, 1.4m high and 0.9m above the ground. During the production process, a hopper with a slope is placed in front of the furnace door. The hopper is 2.1m long, 2.2m wide and 1.5m high. Aluminum ingots or recycled material blocks are placed on the hopper with a forklift. Then the furnace door is fully opened and the fork of the forklift is used to push the material into the furnace. After adding appropriate amount of material, the hopper is removed and the furnace door is closed to complete the feeding process.

[0011] 2. The whole process has the following problems:

[0012] A. When the furnace door is fully opened, the energy loss is too great, which increases the smelting cost.

[0013] B. All furnace doors are open, causing the ambient temperature to rise, which can easily cause heatstroke among on-site workers and pose a safety hazard.

[0014] C. Due to the increase in ambient temperature, the seals of the forklift system are seriously damaged, increasing the equipment maintenance cost. At the same time, the forklift is too close to the furnace door, and there are serious safety hazards when the forklift mast is operated in the upper position. The above shortcomings are all caused by the furnace door being fully opened.

[0015] D. Since the stacks of materials are pushed into the melting furnace by a forklift, it is easy to cause local accumulation in the furnace. At this time, it is necessary to use a forklift or operators to use special tools to push and stir them. This process increases labor intensity and safety risks and also increases energy consumption losses. Summary of the Invention

[0016] The purpose of the embodiments of the present application is to provide a continuous automatic loading mechanism and loading method for a melting furnace, which does not require the furnace door to be fully opened, and workers do not need to operate close to the furnace door, thereby reducing the labor intensity of workers.

[0017] To achieve the above objectives, this application provides the following technical solutions:

[0018] In the first aspect, an embodiment of the present application provides a continuous automatic feeding mechanism for a melting furnace, comprising a material support, a pendulum and a mechanism body, wherein the material support is installed on the mechanism body to support the aluminum ingot to a corresponding height, and the pendulum is used to quickly feed the aluminum ingot that has reached the corresponding height into the melting furnace, the pendulum is connected to the lower end of the pendulum arm, and the upper end of the pendulum arm is connected to the transmission shaft, and the transmission shaft is connected to the pendulum arm drive system, and the mechanism body is also equipped with a double-row transmission chain for driving the aluminum ingot to run, and the double-row transmission chain is driven by a sprocket, and the double-row transmission chain is also provided with a positioning block for positioning the aluminum ingot on the double-row transmission chain, and the mechanism body is also provided with a front-end sensor, a rear-end sensor and an upper sensor, and the front-end sensor and the rear-end sensor are used to monitor the position of the aluminum ingot on the double-row transmission chain, and the upper sensor is used to monitor the position of the pendulum arm.

[0020] The sprocket is connected to the synchronous pulley, the synchronous pulley is connected to the synchronous belt transmission system, the synchronous belt transmission system is connected to the main reducer, the main reducer is connected to the V-belt transmission system, the V-belt transmission system is connected to the main motor, the main motor drives the V-belt transmission system to rotate, the V-belt transmission system drives the main reducer, the main reducer drives the synchronous belt transmission system to rotate, the synchronous belt transmission system drives the synchronous pulley to rotate, the synchronous pulley drives the sprocket to rotate, and the sprocket drives the double-row transmission chain.

[0021] The main body of the mechanism is also provided with a lifting guide wheel system, a tension adjustment pressure wheel system and a tension adjustment supporting wheel. The tension adjustment pressure wheel system and the tension adjustment supporting wheel manually adjust the chain tension. The lifting guide wheel system ensures that the double-row transmission chains and aluminum ingots move linearly in the same plane.

[0022] An anchor bolt is embedded below the rear end of the mechanism body, and a fastening nut and a plane bearing are provided on the upper end of the anchor bolt. The plane bearing supports the mechanism body, and the fastening nut fastens the mechanism body.

[0023] There are two fastening bolts at the corresponding position of the front end of the mechanism body, and two pre-buried anchor nuts at the corresponding position on the ground. The mechanism body is fixed by using the two fastening bolts and the pre-buried anchor nuts.

[0024] Two universal wheels are provided at the bottom of the front end of the mechanism body to support the mechanism body.

[0025] A lifting cylinder is provided below the material bracket.

[0026] The melting furnace is provided with a material hole for convenient feeding of aluminum ingots.

[0027] In a second aspect, an embodiment of the present application provides a method for continuous automatic loading of a melting furnace, comprising the following specific steps:

[0028] The aluminum ingot is placed between the four positioning blocks on the double-row transmission chain at the rear end of the mechanism body. The rear sensor receives and sends a signal, and sends a rotation command to the main motor. The power is output by the main motor and transmitted to the main reducer through the V-belt transmission system. Then, the output shaft of the main reducer is transmitted to the synchronous pulley through the synchronous belt transmission system. The power of the synchronous pulley is transmitted to the sprockets on both sides by the pulley shaft and key. The sprocket drives the double-row transmission chain, the positioning blocks and the aluminum ingot to move forward in a straight line.

[0029] When the double-row transmission chain and positioning block drive the aluminum ingot to the front position, the front sensor receives the signal and issues a command to complete the following actions:

[0031] The lifting cylinder air supply system starts working, supplying air to the cylinder, and the material bracket rises to lift the aluminum ingot to the corresponding position;

[0032] When the material bracket lifts the aluminum ingot to the corresponding height, the front sensor sends an operating instruction to the auxiliary motor;

[0033] After receiving the operation command, the auxiliary motor starts to operate, transmitting power to the reducer through the belt drive system, and then to the large gear through the intermittent gear to drive the transmission shaft to operate. The transmission shaft transmits power to the pendulum and drives the pendulum to the corresponding height. When the pendulum reaches the corresponding height, the upper sensor receives the signal and issues a command to complete the following actions:

[0034] The auxiliary motor stops supplying power, and the intermittent gear stops at the position where the opening faces the large gear. At this time, the large gear can rotate freely. Due to gravity, the pendulum of the pendulum rotates, and the potential energy of the pendulum is converted into kinetic energy. The pendulum uses the energy to hit the aluminum ingot, quickly sending it into the melting furnace.

[0035] After the pendulum completes its action, due to the impact, the pendulum drives the pendulum rod to rebound in the opposite direction. When the pendulum rod reaches the corresponding position, the upper sensor sends a signal, the lifting cylinder air supply system stops supplying air, and the lifting cylinder moves down.

[0036] When the lifting cylinder reaches the lowest position, the front sensor sends a signal command, the main motor starts running, and the entire system completes the next cycle.

[0058] A lifting cylinder 24 is provided below the material bracket 1 .

[0059] The melting furnace 28 is provided with a material hole for convenient feeding of the aluminum ingot 29 .

[0060] like Figure 1 As shown, the embodiment of the present application also provides a method for continuous automatic loading of a melting furnace, comprising the following specific steps:

[0061] The aluminum ingot 29 is placed between the four positioning blocks 12 on the double-row transmission chain 13 at the rear end of the mechanism body 25. The rear-end sensor 11 receives and sends a signal, and sends a rotation command to the main motor 21. The power is output by the main motor 21 and transmitted to the main reducer 19 through the V-belt transmission system 20. The output shaft of the main reducer 19 is then transmitted to the synchronous pulley 15 through the synchronous belt transmission system 16. The power of the synchronous pulley 15 is transmitted to the sprockets 14 on both sides by the pulley shaft and key. The sprocket 14 drives the double-row transmission chain 13, the positioning blocks 12 and the aluminum ingot 29 to move forward in a straight line.

[0062] When the double-row transmission chain 13 and the positioning block 12 drive the aluminum ingot 29 to the front end position, the front end sensor 30 receives the signal and issues a command to complete the following actions:

[0063] The main motor 21 stops and brakes immediately, and the aluminum ingot 29 maintains its current position;

[0064] The air supply system of the lifting cylinder 24 starts working, supplying air to the cylinder, and the material bracket rises to lift the aluminum ingot 29 to the corresponding position;

[0065] When the material bracket 1 carries the aluminum ingot 29 to the corresponding height, the front sensor 30 sends an operation instruction to the auxiliary motor 9;

[0066] After receiving the operation command, the auxiliary motor 9 starts to operate, and transmits the power to the reducer 7 through the belt transmission system 8. Then, the power is transmitted to the large gear 5 by the intermittent gear 6 to drive the transmission shaft 4 to operate. The transmission shaft 4 transmits the power to the pendulum 3 and drives the pendulum 2 to the corresponding height. When the pendulum 3 reaches the corresponding height, the upper sensor 32 receives the signal and issues a command to complete the following actions:

[0067] The auxiliary motor 9 stops supplying power, and the intermittent gear 6 stops at a position where the opening faces the large gear 5. At this time, the large gear 5 can rotate freely. Due to gravity, the pendulum 2 of the pendulum rod 3 rotates, and the potential energy of the pendulum 2 is converted into kinetic energy. The pendulum 2 uses this energy to forcefully hit the aluminum ingot 29, quickly sending it into the melting furnace 28.

[0068] After the pendulum 2 completes its movement, due to the impact, the pendulum 2 drives the pendulum rod 3 to rebound in the opposite direction. When the pendulum rod 3 reaches the corresponding position, the upper sensor 32 sends a signal, the air supply system of the lifting cylinder 24 stops supplying air, and the lifting cylinder 24 descends.

[0069] When the lifting cylinder 24 reaches the lowest position, the front sensor 30 sends a signal command, the main motor 21 starts to run, and the entire system completes the next cycle.

The tension adjustment system can manually adjust the chain tension, and the lifting guide wheel system can basically ensure that the chain and the aluminum ingots move linearly in the same plane.

[0071] If there is no site restriction and the power is sufficient, the device can be extended indefinitely. In actual application, the rear end can be made lower than the front end to facilitate workers' operation.

[0072] To facilitate slag removal and stirring within the furnace, this device is designed as a rotatable system. Pre-embedded anchor bolts are provided at the rear end, and the device body is supported by a flat bearing. These pre-embedded anchor bolts have nuts that secure the body. When the front end rotates, it is supported by two universal casters. These casters allow the device to rotate 90° left and right, each around the pre-embedded anchor bolts.

[0073] There are two fastening bolts at the corresponding position of the front end of the mechanism body, and two pre-buried anchor nuts at the corresponding position on the ground. When the device is in working state, the two fastening bolts can be used to fix the device to avoid vibration and jumping during operation, which will affect the accuracy and stability of the machine operation.

[0074] Since the dimensions of aluminum ingots and aluminum regrind are different, the sprocket shaft can be designed as a positive and negative wire adjustment shaft to adjust the width between the two sprockets, and at the same time adjust the positioning block on the chain to meet the requirements of different material dimensions.

[0075] The above description is merely an embodiment of the present application and is not intended to limit the scope of protection of the present application. For those skilled in the art, various modifications and variations of the present application are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
