Description

Technical Field

[0001] This utility model relates to the field of material handling technology, specifically to a handling vehicle that facilitates unloading from a rotary kiln. Background Technology

[0002] Rotary kilns are widely used for melting various metal scraps. This equipment achieves uniform heating of the internal materials through continuous rotation, thereby gradually melting the metal scraps filled into the furnace into liquid metal. In actual scenarios, the metal scraps heated into liquid state by the tilting rotary kiln often need to be stored in aluminum ladles for transfer to the next processing stage.

[0003] However, due to the often high temperature of liquid metal, it is impossible to manually pour it into the aluminum ladle. Therefore, a guide channel is usually used to guide the liquid metal into the aluminum ladle. However, because a certain space needs to be left at the discharge port of the rotary kiln for workers to add material (tilting rotary kilns generally share a single furnace opening for both the feeding and discharge ports, such as the rotary kiln in the patent with publication number CN211695826U), the guide channel is often set to be too long. As a result, the temperature of the liquid metal drops after it flows into the aluminum ladle, making it impossible to efficiently store the liquid metal. Summary of the Invention

[0004] This invention addresses the problem in existing technology where the overall temperature of molten metal, heated to a molten state in a tilting rotary kiln, drops as it flows through a long guide channel into the aluminum ladle. The invention provides a transport vehicle that facilitates unloading from the rotary kiln. This transport vehicle can move the aluminum ladle to the discharge port of the tilting rotary kiln and is equipped with a guide component that directly guides the molten metal into the aluminum ladle, facilitating unloading from the rotary kiln and preventing excessive heat loss from the molten metal.

[0005] The technical solution of this utility model is: a transport vehicle for easy unloading of material from a rotary kiln, including a frame, wheels and a flow guiding assembly. The wheels are located at the bottom of the frame, and the frame can hold a storage box. The flow guiding assembly includes a flow guiding channel and a power unit. The flow guiding channel is rotatably connected to the frame, and the power unit is used to drive the flow guiding channel to rotate relative to the frame, so that the flow guiding channel can rotate to one end corresponding to the feed inlet of the storage box and the other end corresponding to the discharge outlet of the rotary kiln.

[0006] Using the above scheme, the chassis can hold the storage box, allowing the chassis to move easily under the drive of the wheels, thus efficiently transporting the storage box. By setting the guide channel in the guide component, one end can be rotated to correspond to the feed inlet of the storage box and the other end to the discharge outlet of the rotary kiln, so that the heated liquid metal can be introduced into the storage box by the rotary kiln turning over, which facilitates the unloading of the rotary kiln. Since the guide channel is directly connected to the feed inlet of the storage box and the discharge outlet of the rotary kiln, the liquid metal can quickly enter the storage box, thus avoiding the loss of heat from the liquid metal.

[0007] Based on the above solution, the present invention can be further improved as follows:

[0008] Furthermore, support rods are provided on the frame on both sides of the guide channel, and the guide channel is rotatably connected to the support rods. The support rods ensure that the guide channel never comes into contact with the frame.

[0009] With the above-mentioned further solution, the guide channel will never come into contact with the vehicle frame during rotation under the support of the support rod, which can avoid unnecessary collisions between the guide channel and the vehicle frame, thereby preventing damage to the guide channel.

[0010] Furthermore, the power unit is a telescopic structure, and the telescopic movement of the telescopic structure causes the guide channel to rotate relative to the vehicle frame.

[0011] Furthermore, the telescopic structure is an electric push rod, with the push rod end of the electric push rod rotatably connected to the guide channel and the base end of the electric push rod rotatably connected to the vehicle frame.

[0012] By adopting the above-mentioned further solution, the guide channel can be rotated by controlling the extension and retraction of the electric push rod.

[0013] Furthermore, the wheels are provided with grooves, enabling the transport vehicle to move along a set track path, thereby ensuring the stability of the transport vehicle during the transfer of storage boxes.

[0014] Furthermore, the rotation plane of the guide channel is perpendicular to the movement path of the transport vehicle, and a baffle is provided at the bottom of the guide channel when the telescopic structure is not extended.

[0015] By adopting the above-mentioned further solution, the baffle is set so that even if liquid metal adheres to the surface of the guide channel, it is not easy to drip onto the ground.

[0016] Furthermore, a support platform is provided in the middle of the vehicle frame, the storage box is placed on the support platform, and the support rod is perpendicular to the support platform.

[0017] Furthermore, the support platform is equipped with a guard plate on the frame at its edge to prevent the storage box from falling off during transport.

[0018] Furthermore, the frame is also equipped with a motor, the output end of which is connected to the wheels. By controlling the rotation direction and start / stop of the motor, the storage box can be transported.

[0019] Furthermore, the frame is also equipped with a battery that provides power to the motor and electric actuator.

[0020] The beneficial effects of this utility model through the above technical solution are as follows:

[0021] 1. In this utility model, the frame can hold the storage box, allowing the frame to move easily under the drive of the wheels, thereby efficiently transporting the storage box; and by setting the guide channel in the guide component, one end can be rotated to correspond to the feed port of the storage box and the other end to correspond to the discharge port of the rotary kiln, so that the heated liquid metal can be introduced into the storage box by the rotary kiln turning over, which facilitates the unloading of the rotary kiln. Moreover, since the guide channel is directly connected to the feed port of the storage box and the discharge port of the rotary kiln, the liquid metal can quickly enter the storage box, thereby avoiding the heat loss of the liquid metal.

[0022] 2. In a further embodiment of this utility model, the guide channel will never come into contact with the vehicle frame during rotation under the support of the support rod, which can avoid unnecessary collisions between the guide channel and the vehicle frame, thereby preventing damage to the guide channel; at the same time, the baffle makes it difficult for liquid metal to drip onto the ground even if it adheres to the surface of the guide channel.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] like Figures 1-3As shown, a transport vehicle for easy unloading of rotary kiln includes a frame 1, wheels 2 and a flow guide assembly 3. The frame 1 is square, and the wheels 2 are located at the bottom of the frame 1 and at the four corners of the frame 1. The frame 1 can hold a storage box, which is an aluminum ladle. This allows the frame 1 to move easily under the drive of the wheels 2, thereby efficiently transferring the storage box.

[0029] The flow guiding assembly 3 includes a flow guiding channel 301 and a power unit. The flow guiding channel 301 is rotatably connected to the frame 1. The cross-section of the flow guiding channel is U-shaped. The power unit is used to drive the flow guiding channel 301 to rotate relative to the frame 1, so that the flow guiding channel 301 can rotate to one end corresponding to the feed inlet of the storage tank and the other end corresponding to the discharge outlet of the rotary kiln. This allows the heated liquid metal to be introduced into the storage tank by the rotary kiln through rotation, which facilitates the unloading of the rotary kiln. Since the flow guiding channel is directly connected to the feed inlet of the storage tank and the discharge outlet of the rotary kiln, the liquid metal can quickly enter the storage tank, thereby avoiding heat loss of the liquid metal.

[0030] As one possible implementation, support rods 302 are provided on the frame 1 on both sides of the guide channel 301. The guide channel 301 is rotatably connected to the support rods 302. The support rods 302 ensure that the guide channel 301 never contacts the frame 1. This can prevent unnecessary collisions between the guide channel 301 and the frame 1, thereby preventing damage to the guide channel 301.

[0031] In one possible implementation, the power unit is a telescopic structure, and the telescopic movement of the telescopic structure causes the guide groove 301 to rotate relative to the frame 1.

[0032] In one possible implementation, the telescopic structure is an electric push rod 303. The push rod end of the electric push rod 303 is rotatably connected to the guide channel 301, and the base end of the electric push rod 303 is rotatably connected to the vehicle frame 1, so that the guide channel 301 can be rotated by controlling the extension and retraction of the electric push rod 303; Figure 3 Based on the orientation shown, when the telescopic structure is not extended, the bottom end of the guide channel 301 is provided with a baffle 304. When the electric push rod 303 is extended, the lower end of the guide channel 301 gradually rotates from the lower left to the upper left, so that the end with the baffle 304 is connected to the discharge port of the rotary kiln. This makes it difficult for liquid metal to drip onto the ground even if the surface of the guide channel 301 is covered with liquid metal when the lower end of the guide channel 301 rotates to the lower left.

[0033] As one possible implementation, the wheel 2 is provided with grooves, which enables the transport vehicle to move along a set track path, thereby ensuring the stability of the transport vehicle during the transfer of the storage box.

[0034] As one possible implementation method, Figure 1 Based on the orientation shown, the wheel 2 is provided with grooves along the left and right directions, so that the transport vehicle can move along the set track path, thereby ensuring the stability of the transport vehicle during the transfer of the storage box; the flow guiding component 3 is provided on the rear frame 1, and the center line of rotation of the flow guiding channel 301 is also along the left and right directions, so that the rotation plane of the flow guiding channel 301 is perpendicular to the movement path of the transport vehicle, thereby enabling the transport vehicle to move to the position of the flow guiding channel 301 below the discharge port of the rotary kiln, so that the flow guiding channel 301 can rotate to connect with the discharge port of the rotary kiln.

[0035] As one possible implementation, a support platform 101 is provided in the middle of the frame 1, the storage box is placed on the support platform 101, and the support rod 302 is perpendicular to the support platform 101.

[0036] As one possible implementation, a guard plate 102 is provided on the frame 1 at the edge of the support platform 101 to prevent the storage box from falling off during transportation.

[0037] As one possible implementation, the frame 1 is also equipped with a motor 4 and a battery 5. The output end of the motor 4 is connected to the wheel 2. By controlling the rotation direction and start and stop of the motor 4, the storage box can be transferred. The battery 5 provides power to the motor 4 and the electric push rod 303.

[0038] In this embodiment, the motor 4 is model XQ-3kwX2, and is used in conjunction with the reducer GF-68×2 to drive the wheel 1 to rotate. The battery 5 is a 48V 400Ah lithium battery, which provides power to the motor 4 and the electric push rod 303. The start and steering of the motor 4 are controlled by a handle button and remote control (this button and remote control method can adopt the control method in the prior art, such as the control method of remote control racing cars, etc.), so that the operator can operate from a safe distance from the transport vehicle. This not only avoids the safety risks caused by close-range operation by personnel in dangerous environments, but also improves the convenience of operation.

[0039] In this embodiment, when used:

[0040] Workers operate the transport vehicle from a safe distance using a handle button and remote control to move it under the rotary kiln, ensuring that the guide trough 301 is aligned with the discharge port of the rotary kiln. Then, by controlling the button, the electric push rod 303 extends, causing one end of the guide trough 301 with the baffle 304 to rotate and align with the discharge port of the rotary kiln, while the other end of the guide trough 301 aligns with the inlet of the aluminum ladle. By controlling the rotation of the rotary kiln (which is controlled by another method), the liquid metal can be guided through the guide trough 301 into the aluminum ladle.

[0041] After all the molten metal in the rotary kiln has been poured out, the rotary kiln is first restored to its original state. Then, the electric push rod 303 is retracted via a button, causing the end of the guide trough 301 equipped with the baffle 304 to rotate to the position where... Figure 3 As shown, by blocking the inlet of the molten aluminum ladle, the transport vehicle can be controlled via the handle button and remote control to transfer the molten aluminum ladle to the next processing stage.
