Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a uniform feeding device for continuous casting of copper-aluminum composite plates. Background Technology

[0002] Copper-aluminum composite strip is a commonly used type of metal composite sheet. It is made by combining copper and aluminum together. The common manufacturing method is to first melt aluminum into liquid and continuously cast it to obtain aluminum strips. Then, it is pressed together with heated copper strips through rolling equipment. The commonly used continuous casting machine consists of a ladle turntable, tundish, crystallizer, cooling nozzles, etc. The aluminum sheet is cooled and formed in the crystallizer and then pulled out to form a whole aluminum strip.

[0003] In the existing technology, copper and aluminum strips need to be fed into the corresponding melting equipment by a feeding device before rolling to heat and melt them so that the copper and aluminum strips can be rolled into shape. However, the feeding devices on the market are not convenient for uniform feeding and have the problem of difficulty in accurately controlling the feeding amount, thus adding unnecessary burden to the heating furnace.

[0004] To address this issue, a uniform feeding device for continuous casting of copper-aluminum composite plates is proposed, which has the advantage of easy and precise control of the feed rate, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a uniform feeding device for continuous casting of copper-aluminum composite plates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a uniform feeding device for continuous casting of copper-aluminum composite plates, comprising a storage tank, a mounting frame welded to the bottom of the storage tank, and a feeding cylinder fixed to the inner side of the mounting frame by bolts; a guide shell welded to the inner side of the mounting frame is provided below the feeding cylinder, and a gate valve is installed at the material nozzle at the bottom of the feeding cylinder; a discharge hole is opened on the bottom surface of the storage tank, and the discharge hole is connected to the feeding cylinder; a motor is fixed on the top surface of the storage tank, and a stirring shaft is fixed to the output end of the motor through a coupling; several sets of stirring rods are equidistantly installed on the surface of the stirring shaft, and a disc is fixed at the bottom of the stirring shaft; a circular hole is opened on the surface of the disc, and a guide block is welded to the top surface of the disc.

[0007] As a further description of the above technical solution: a feed nozzle is connected to the edge of the top surface of the storage tank, and a flip cover is installed at the port of the feed nozzle by a hinge.

[0008] As a further description of the above technical solution: the guide shell is inclined about the mounting frame, and one end of the guide shell is integrally cast with a conical part.

[0009] As a further description of the above technical solution: the surface of the storage barrel is provided with a rectangular opening, and tempered glass is embedded in the rectangular opening.

[0010] As a further description of the above technical solution: the inner diameter of the circular hole is adapted to the inner diameter of the discharge hole of the storage barrel, and one of the points on the moving trajectory of the circular hole coincides with the position of the discharge hole.

[0011] As a further description of the above technical solution: the guide block has an overall triangular structure, and the guide block is set near the circular hole of the disk.

[0012] As a further description of the above technical solution: a rubber sealing ring is embedded in the top surface of the feeding cylinder, and the rubber sealing ring abuts against the inner side of the mounting frame; a mounting ear is welded to the upper surface of the feeding cylinder, and bolts connected to the mounting frame are inserted through the surface of the mounting ear.

[0013] This utility model has the following beneficial effects:

[0014] This invention comprises a storage hopper, a feeding cylinder, and a guide shell. A motor drives a stirring shaft to rotate, causing multiple stirring rods on the shaft to agitate the metal powder in the storage hopper. The stirring shaft then drives a disc and its top triangular guide block to agitate the metal powder at the bottom of the storage hopper, maintaining the powder's looseness. When the disc's circular hole aligns with the discharge hole at the bottom of the storage hopper, the metal powder falls into and fills the feeding cylinder. During the gate valve opening phase, the metal powder in the feeding cylinder is naturally discharged under gravity until it is guided by the inclined guide shell and fed into the heating furnace to melt into a liquid state. This feeding method offers advantages such as simple structure and precise control of the feed rate, solving the problem of uneven feed rate burdening the heating furnace.

A motor 4 is fixed on the top surface of the storage tank 1, and a stirring shaft 10 is fixed to the output end of the motor 4 through a coupling. Several sets of stirring rods are equidistantly installed on the surface of the stirring shaft 10. 11, and a disc 12 is fixed at the bottom of the stirring shaft 10. A circular hole 13 is opened on the surface of the disc 12, and a guide block 14 is welded to the top surface of the disc 12. The control method of the motor 4 in this utility model is to control it by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. In addition, this utility model is mainly used to protect mechanical devices, so the control method and wiring arrangement will not be explained in detail in this utility model. In order to facilitate installation, the extension parts on both sides of the inverted U-shaped structure mounting bracket 2 are provided with mounting holes. The metal powder of this device can be copper powder or aluminum powder.

[0024] In one embodiment, a feed nozzle 3 is connected to the edge of the top surface of the storage tank 1, and a flip cover is installed at the port of the feed nozzle 3 by a hinge. With this structure, it is easy to cover the feed nozzle 3 during the stirring stage to prevent metal powder leakage.

[0025] In one embodiment, the guide shell 6 is inclined about the mounting bracket 2, and one end of the guide shell 6 is integrally cast with a conical part 7. This structure is beneficial for guiding the metal powder and feeding it accurately into the heating furnace.

[0026] In one embodiment, a rectangular opening is provided on the surface of the storage bin 1, and a tempered glass 9 is embedded in the rectangular opening. With this structure, the remaining amount in the storage bin 1 can be observed intuitively.

With this structure, it is easy to discharge metal powder after the circular hole 13 and the discharge hole 15 coincide, which is beneficial to uniform feeding.

[0028] In one embodiment, the guide block 14 is generally triangular in shape and is positioned close to the circular hole 13 of the disc 12.

[0030] Working principle:

[0031] In use, first fix the mounting frame 2 to the feeding position of the heating furnace, and then use the vertical elevator to feed the metal powder into the feeding nozzle 3 until the metal powder fills the storage tank 1. When the heating furnace is being fed, start the motor 4 to drive the stirring shaft 10 to rotate, causing the multiple stirring rods 11 on the stirring shaft 10 to stir the metal powder in the storage tank 1. Then, the stirring shaft 10 drives the disc 12 and the triangular guide block 14 on its top surface to stir the metal powder at the bottom of the storage tank 1, keeping the metal powder loose. When the round hole 13 of the disc 12 coincides with the discharge hole 15 on the bottom surface of the storage tank 1, the metal powder falls into and fills the feeding cylinder 5. During the opening stage of the gate valve 8, the metal powder in the feeding cylinder 5 is naturally discharged under the action of gravity until it is fed into the heating furnace to melt into liquid under the guidance of the inclined guide shell 6. When it is necessary to adjust the feeding amount, disassemble the feeding cylinder 5 and then replace it with a feeding cylinder 5 of appropriate capacity.
