Detailed Implementation

[0042] To make the technical solutions and advantages in the embodiments of this application clearer, the following description is provided in conjunction with the appendix. Figure 1-4 The exemplary embodiments of this application will be described in further detail below. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0043] In the process of developing this application, the inventors discovered that during the smelting of aluminum ingots, workers transport the ingots to the furnace opening platform and push them into the furnace using a pusher rake. This pushing process is achieved using a forklift. This feeding process requires first opening the furnace lid and then manually adding the material, which is not only time-consuming and labor-intensive but also prone to causing heat loss from the furnace. Because the area near the furnace feeding port is constantly exposed to high temperatures during aluminum ingot processing, existing automatic feeding devices are difficult to use for extended periods due to the high temperatures. Furthermore, the fixed size of the feeding port cannot accommodate materials of different volumes, affecting the electrode switching operation.

[0044] To address the aforementioned problems, this application provides a feeding port switching mechanism, such as... Figures 1-4 As shown, it includes:

[0045] Positioning frame 101: Located above the feeding port, and the shape of the positioning frame 101 is adapted to the shape of the feeding port;

[0046] Fixing plate 102: placed on one side inside the positioning frame 101, covering part of the feeding port;

[0047] Opening and closing plate 103: It is movably installed on the other side of the positioning frame 101 and is connected to the driving end of the driving mechanism 20. Under the action of the driving mechanism 20, the opening and closing plate 103 can open or close the other part of the feeding port.

[0048] In practice, the positioning frame 101 is installed on the feeding port. Under normal circumstances, the opening and closing plate 103 is in the closed state (e.g., Figure 2As shown), its own weight, together with the fixing plate 102, seals the positioning frame 101, achieving a reliable seal on the feeding port and preventing temperature loss from the smelting furnace. When a pole-changing operation is required or a large volume of material needs to be fed, the drive mechanism 20 is activated. The opening and closing plate 103, which is movably connected to the positioning frame 101, rotates from the closed state to the open state under the drive of the output end of the drive mechanism 20 (as shown). Figure 1 As shown), the other part of the positioning frame 101 that was originally blocked by the opening and closing plate 103 is completely opened to form a feeding port for the feeding of large volume materials or the addition of electrode graphite rods for electrode replacement. After the electrode replacement is completed or the addition of large volume materials is not required for the time being, the drive mechanism 20 resets the opening and closing plate 103.

[0049] As a preferred option, such as Figure 3 As shown, the positioning frame 101 includes:

[0050] Border 104: Set on the feeding port, the shape of the border 104 is adapted to the shape of the feeding port;

[0051] Limiting frame 105: Horizontally set on the inner side of the bottom of the frame 104, the limiting frame 105 is used to support and limit the bottom surface of the fixing plate 102 and the opening and closing plate 103;

[0052] Rotating shaft 106: Installed on the side of the frame 104 away from the fixed plate 102, the opening and closing plate 103 is hinged to the frame 104 via the rotating shaft 106.

[0053] In practice, the shape of the frame 104 is adapted to the shape of the fixed plate 102 and the opening and closing plate 103. The bottom surface of the fixed plate 102 abuts against the limiting frame 105, and the side surface of the fixed plate 102 is in close contact with the frame 104, covering and sealing a part of the positioning frame 101. One side of the opening and closing plate 103 is hinged to the side of the frame 104 away from the fixed plate 102 through the pivot 106. In the closed state, the bottom surface of the opening and closing plate 103 abuts against the limiting frame 105, and the side surface is in close contact with the frame 104, sealing the other part of the positioning frame 101.

[0054] As a preferred embodiment, the fixing plate 102 is provided with a first inclined surface 107 on the side near the opening and closing plate 103, and the angle between the first inclined surface 107 and the bottom surface of the fixing plate 102 is an acute angle.

[0055] The opening and closing plate 103 is provided with a second inclined surface 108 on the side near the fixed plate 102. Corresponding to the first inclined surface 107, the angle between the second inclined surface 108 and the bottom surface of the opening and closing plate 103 is complementary to the angle between the first inclined surface 107 and the bottom surface of the fixed plate 102.

[0056] The first inclined surface 107 and the second inclined surface 108 fit tightly together when the opening and closing plate 103 is closed.

[0057] As a preferred embodiment, the fixing plate 102 is provided with a feed inlet 109, which is located on one side of the first inclined surface 107. The first inclined surface 107 is provided with a first notch 1010, and the feed inlet 109 is connected to the first notch 1010.

[0058] In specific implementation, in the closed state, the first inclined surface 107 and the second inclined surface 108 are tightly fitted together, sealing the feeding port. The inlet 109 of the fixed plate 102 can be used to feed small-volume materials. The opening and closing plate 103 is pressed onto the first inclined surface 107 of the fixed plate 102 by the second inclined surface 108. By setting the contact surface between the fixed plate 102 and the opening and closing plate 103 as an inclined surface that can fit tightly together, the gap between the contact surface of the fixed plate 102 and the opening and closing plate 103 is effectively sealed, further sealing the positioning frame 101 and further strengthening the sealing of the feeding port. Moreover, the setting of the inclined surface helps the opening and closing plate 103 to reset by its own weight, and during the reset, it uses its own weight and the inclined surface to seal and press the fixed plate 102. Even if the drive end of the drive mechanism 20 is loose, it will not affect the reset of the opening and closing plate 103. The included angle between the first inclined surface 107 and the bottom surface of the fixed plate 102 The acute angle is designed to avoid interference with the opening and closing of the hinge plate 103. When the hinge plate 103 is closed, the close fit, smooth surface, and large contact area between the first inclined surface 107 and the second inclined surface 108 bring the intermolecular distance very close. The intermolecular attraction, such as van der Waals forces, pulls the two surfaces together. At the same time, the smooth surface has fewer impurities and defects, which allows the surface tension to more effectively "bond" the two surfaces together. This means that when the hinge plate 103 is opened, it must not only resist its own gravity but also the surface tension. By setting a second notch 205 on the first inclined surface 107 and connecting it to the feed port 109, the surface tension formed between the first inclined surface 107 and the second inclined surface 108 is effectively reduced, which is more conducive to opening the hinge plate 103. This reduces the work required by the drive mechanism 20 and extends its lifespan.

[0059] To address the aforementioned issues, this application also provides a switch device for the feed port of a precision aluminum tank, such as... Figures 1-4 As shown, it includes:

[0060] Switching mechanism 10: is the feeding port switching mechanism provided in the above embodiment, and the positioning frame 101 in the switching mechanism 10 is located above the feeding port of the fine aluminum tank;

[0061] Drive mechanism 20: includes:

[0062] Base 201: Located on the side of the positioning frame 101 near the opening and closing plate 103;

[0063] Take-up shaft 202: Rotatably mounted on base 201 via bearing seat, and a braking device is installed on take-up shaft 202;

[0064] Traction rope 203: One end of the traction rope 203 is connected to the top surface of the opening and closing plate 103, and the other end of the traction rope 203 is wound around the winding shaft 202. The driving end of the driving mechanism 20 is the end of the traction rope 203 connected to the opening and closing plate 103.

[0065] As a preferred option, such as Figure 4 As shown, the drive mechanism 20 also includes:

[0066] Motor 208: Located on one side of the winding shaft 202 on the base 201;

[0067] Reducer 209: Its input shaft is connected to the output shaft of motor 208, and the output shaft of reducer 209 is connected to winding shaft 202 through a coupling.

[0068] In practice, when a pole-changing operation is required or a large volume of material needs to be fed, the drive mechanism 20 is started. The motor 208 transmits power to the winding shaft 202 through the reducer 209. By rotating the winding shaft 202, the traction rope 203 is wound up, thereby driving the opening and closing plate 103 to rotate outward around the hinge point towards the positioning frame 101 until the other part of the positioning frame 101 blocked by the opening and closing plate 103 is completely opened to form a feeding port. The opening angle of the opening and closing plate 103 is set so as not to affect the pole-changing operation or the passage of large volume of material through the feeding port.

[0069] As a preferred embodiment, the drive mechanism 20 further includes:

[0070] Vertical plate 204: disposed between base 201 and positioning frame 101;

[0071] A second notch 205 is provided above the vertical plate 204;

[0072] At the second notch 205, a rope winding shaft 206 is rotatably mounted via a bearing seat;

[0073] The other end of the traction rope 203 passes through the second notch 205, goes over the rope shaft 206, and then wraps around the take-up shaft 202.

[0074] As a preferred embodiment, the drive mechanism 20 further includes:

[0075] Buffer component 207: Located on the top of the vertical plate 204 near the positioning frame 101. During the opening and closing process of the opening and closing plate 103 under the action of the traction rope 203, the buffer component 207 abuts against the opening and closing plate 103 and contracts to store elastic potential energy.

[0076] In practice, to facilitate the passage of the traction rope 203 through the vertical plate 204, a second notch 205 is made above the vertical plate 204. As the opening / closing plate 103 rotates from the closed state to the open state, the motor 208 and reducer 209 drive the winding shaft 202 to wind it up. The taut traction rope 203 applies traction force to the opening / closing plate 103. After the opening / closing plate 103 rotates 90 degrees, its top surface abuts against the buffer assembly 207, and winding continues until the buffer assembly 207 is compressed under the continued rotation of the opening / closing plate 103, storing sufficient spring force for the opening / closing plate 103 to rebound. The elastic potential energy is stored in the buffer assembly 207. At this time, the motor 208 is turned off and the braking device is activated to brake the winding shaft. With the assistance of the buffer assembly 207, smooth braking is achieved, thereby storing the elastic potential energy stored in the buffer assembly 207 when the opening and closing plate 103 is in the open state. When the pole changing operation is completed or when it is not necessary to add large volume materials temporarily, the braking device is released, the elastic potential energy stored in the buffer assembly 207 is released, and the opening and closing plate 103 rotates inward under the push of the buffer assembly 207. After that, the opening and closing plate 103 does not need power and can continue to rotate inward under its own gravity to complete the reset.

[0077] It needs to be emphasized that, Figures 1-4 The installation position of the drive mechanism 20 is only for illustration. In actual application, the motor 208, reducer 209, winding shaft 202 and related components in the drive mechanism 20 are actually kept at a considerable distance from the vertical plate 204. This ensures that the drive mechanism 20 is kept away from high-temperature areas. Combined with the heat insulation effect of the vertical plate 204, its service life is further extended.

[0078] As a supplement to the preferred solution, the vertical plate 204 is a heat insulation plate made of high-temperature resistant materials, such as glass fiber reinforced resin composite material, ceramic fiber board, glass fiber reinforced resin composite material, etc., so that the vertical plate 204 has excellent high-temperature heat insulation performance and is suitable for long-term heat insulation protection of the drive mechanism 20.

[0079] As a preferred embodiment, the buffer assembly 207 is a compression spring.

[0080] As a preferred option, the top surface of the hinged panel 103 is provided with a handle 1011, which can be installed, disassembled, or replaced by a hoisting mechanism.

[0081] As a preferred solution, an automatic aluminum ingot feeding robot can be installed at the feeding port and its operation can be linked with the opening and closing of the opening and closing plate 103 to achieve automated material feeding.

[0082] The feeding port switching mechanism and aluminum trough feeding port switching device provided in this application embodiment achieve reliable sealing of the feeding port by setting a fixed plate and an opening and closing plate inside the positioning frame to block the positioning frame; the opening and closing of the feeding port is automated by driving the hinged opening and closing plate through the drive mechanism, which can realize the feeding of materials of different volumes without removing the positioning frame and the cover plate, and also take into account the pole changing operation; the vertical plate protects the drive mechanism from high temperature damage and extends the service life of the equipment; the opening and closing plate is opened by components such as traction rope and winding shaft, and the buffer component accumulates elastic potential energy during the opening and closing process and completes the closing and resetting by the self-weight of the opening and closing plate, which greatly simplifies the structure required for the automatic opening and closing of the opening and closing plate, and no motor is required during the resetting process, making the structure simple and reliable; the contact surface between the fixed plate and the opening and closing plate is set as an inclined surface that can fit tightly, which helps the opening and closing plate to reset by its own weight, and seals and compacts the fixed plate by its own weight and the inclined surface during the resetting; a second notch communicating with the feeding port is opened on the first inclined surface, which effectively reduces the surface tension between the contact inclined surfaces. The feeding port switch mechanism and the aluminum trough feeding port switch device provided in this application have a simple and reliable structure, can accommodate the feeding of materials of different volumes and the pole changing operation, and can be used for a long time in the feeding operation of smelting furnaces in medium and high temperature environments, and have strong practicality.
