Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to an aluminum alloy electric furnace for casting processing. Background Technology

[0002] Aluminum alloy furnaces are used for heating, melting, solution treatment, heat preservation, and quenching of aluminum alloy products, and are also used for low-temperature tempering of other metal parts.

[0003] Chinese patent document with application number CN202020679709.X, in the related technology, proposes a special smelting electric furnace for aluminum alloy production. It uses a first motor and a second motor on the crushing chamber to drive the first and second crushing rollers to rotate in opposite directions, thereby crushing waste aluminum alloy. The crushed aluminum alloy enters a rotating drum through a fixed cylinder. A heating chamber heats the rotating drum, and a third motor drives the rotating drum to rotate, ensuring even heating and sufficient smelting of the aluminum alloy. During the smelting process, there is residual heat inside the furnace. Water is added to the residual heat recovery tank through the inlet pipe, and the residual heat heats the water. The heated water is then available for use through the outlet pipe. After the aluminum alloy is smelted, it is poured into a recycling tank through the discharge pipe for convenient centralized processing.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: While the device can quickly crush waste aluminum alloys through its design, common waste aluminum alloys often contain a certain number of iron products such as screws or nuts. Existing devices are not convenient for removing these iron products, resulting in a large number of impurities in the recycled aluminum produced later, which reduces the quality of the recycled aluminum products. Therefore, an aluminum alloy electric furnace for casting processing is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: an aluminum alloy electric furnace for casting processing, comprising a base plate, a fixed box fixed on the base plate, a heating box fixed inside the fixed box, a rotating drum inside the heating box, a feeding cylinder on one side of the rotating drum, a cleaning mechanism on the base plate, and a crushing component on the cleaning mechanism.

[0007] The impurity removal mechanism includes a fixed plate, a mounting plate, an impurity removal box, and an electromagnet. The impurity removal box is fixed on the base. Mounting plates are obliquely arranged on both inner walls of the impurity removal box. An electric push rod is fixed inside the mounting plate.

[0010] Furthermore, the impurity removal box has a first discharge port on both sides, and one end of the screening plate is located inside the first discharge port. The screening plate is set at an angle.

[0011] Furthermore, a spring is fixed between one side of the screening plate and the inner wall of the impurity removal box, and multiple blocking blocks are fixed on the screening plate.

[0012] Furthermore, flow guides are fixed on both sides of the impurity removal box, with one end of the flow guide penetrating through the impurity removal box and extending into its interior.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 An aluminum alloy electric furnace for casting processing in this embodiment includes a base plate 1, on which a fixed box 4 is fixed. An external driving device for driving a rotating drum 3 to rotate is provided on the fixed box 4. A heating box 2 is fixed inside the fixed box 4. The rotating drum 3 is provided inside the heating box 2. The inner wall of the heating box 2 is connected to the outer wall of the rotating drum 3 through a bearing. A feed cylinder 5 is provided on one side of the rotating drum 3. A vertical plate is fixed to the top outer wall of the fixed box 4 by screws. A fixed cylinder is fixed to one end of the rotating drum 3 by screws. The outer wall of the fixed cylinder is connected to the outer wall of one side of the vertical plate through a bearing. A cleaning mechanism 7 is provided on the base plate 1. A crushing component 6 is provided on the cleaning mechanism 7.

[0024] The crushing assembly 6 includes a feed box and crushing rollers. The feed box is connected to the impurity removal box 701. Two rotatable crushing rollers are arranged horizontally inside the feed box. One end of the crushing rollers is driven to rotate by an external second motor.

[0025] The impurity removal mechanism 7 includes a fixed plate 704, a mounting plate 705, an impurity removal box 701, and an electromagnet 706. The impurity removal box 701 is fixed on the base. Mounting plates 705 are obliquely arranged on both inner walls of the impurity removal box 701. An electric push rod 702 is fixed inside the mounting plate 705. A push plate 703 is fixed at the output end of the electric push rod 702. The mounting plate 705 is fixed in the middle of the inner side of the impurity removal box 701.

[0026] Multiple electromagnets 706 are horizontally arranged on both sides of the mounting plate 705. One end of the feed cylinder 5 is connected to the bottom of the impurity removal box 701. The lower end of the impurity removal box 701 has a discharge port for discharging aluminum alloy into the feed cylinder 5. A discharge port (not shown in the figure) is provided inside the impurity removal box 701 on the side near the electromagnets 706, which facilitates the removal of iron products attracted by the electromagnets 706 by the operator.

[0027] The device activates an electric push rod 702 and an electromagnet 706 on one side. The electric push rod 702 drives the push plate 703 to move towards the mounting plate 705. Then, the push plate 703 abuts against the mounting plate 705, causing the crushed aluminum alloy in the feed box to fall into the impurity removal box 701. The material then flows from the other side of the push plate 703, where it does not abut against the mounting plate 705, onto the electromagnet 706. The electromagnet 706 then attracts the iron products in the crushed raw material.

[0028] The mounting plate 705 is hinged to both sides with screening plates 707. A rotatable shaft 710 is horizontally arranged inside the impurity removal box 701. One end of the shaft 710 is rotated by an external first motor. Two cams 711 are fixed on the shaft 710. The outer side of the cams 711 is slidably connected to the lower end face of the screening plate 707.

[0029] The impurity removal box 701 has first discharge ports 709 on both sides. One end of the screening plate 707 is located inside the first discharge port 709. The screening plate 707 is inclined. A spring 712 is fixed between one side of the screening plate 707 and the inner wall of the impurity removal box 701. By starting the external first motor, the external first motor shaft 710 rotates, and then the shaft 710 drives two cams 711 to rotate. Subsequently, the cams 711 drive the screening plate 707 to move up and down reciprocally. When the screening plate 707 moves up and down, it stretches the spring 712, which enables the crushed raw material to move up and down reciprocally. Under the magnetic force of the electromagnet 706, iron products in the crushed raw material can be attracted.

[0030] Meanwhile, multiple blocking blocks 714 are fixed on the screening plate 707. By setting the blocking blocks 714, the aluminum alloy stays on the screening plate 707 for a longer time.

[0031] In addition, guide hoods 708 are fixed on both sides of the impurity removal box 701. One end of the guide hood 708 passes through the impurity removal box 701 and extends into its interior. The impurity removal box 701 has a second discharge port 713 on both sides. The first discharge port 709 is located above the second discharge port 713, which facilitates the guidance of the aluminum alloy discharged from both sides of the impurity removal box 701, which then enters the impurity removal box 701 through the second discharge port 713, and then enters the feed cylinder 5 through the discharge port.

[0032] The impurity removal box 701 has a second discharge port 713 on both sides, and the first discharge port 709 is located above the second discharge port 713.

[0033] The working principle of the above embodiments is as follows:

[0034] First, the recycled aluminum alloy is poured into the feed box. Then, the external second motor is started, and the external first motor drives the crushing roller to rotate and crush the aluminum alloy. Then, by starting one side of the electric push rod 702 and electromagnet 706, the electric push rod 702 drives the push plate 703 to move towards the mounting plate 705. Then, the push plate 703 abuts against the mounting plate 705, so that the crushed aluminum alloy in the feed box falls into the impurity removal box 701. Then, it flows from the other side of the push plate 703, where it does not abut against the mounting plate 705, onto the electromagnet 706. The electromagnet 706 then adsorbs the iron products in the crushed raw material.

[0035] The aluminum alloy falls onto the screening plate 707. Then, by starting the external first motor, the external first motor shaft 710 rotates, which in turn drives the two cams 711 to rotate. Subsequently, the cams 711 drive the screening plate 707 to move up and down. When the screening plate 707 moves up and down, it stretches the spring 712, which allows the crushed raw material to move up and down. With the setting of the blocking block 714, the aluminum alloy stays on the screening plate 707 for a longer time. Under the magnetic force of the electromagnet 706, iron products in the crushed raw material can be attracted.

[0036] The aluminum alloy is then discharged from the first discharge port 709, flows into the guide shroud 708, enters the bottom of the impurity removal box 701 through the second discharge port 713, and then enters the feed cylinder 5 through the discharge port, flowing into the rotating drum 3. The heating box 2 heats the rotating drum 3.

[0037] When it is necessary to clean the iron filings on the electromagnet 706, the push plate 703 can be moved towards the mounting plate 705 by activating the electric push rod 702 on one side. Then the push plate 703 abuts against the mounting plate 705, thereby cleaning the iron products on the electromagnet 706. The channel on the other side of the mounting plate 705 can work normally, thus enabling the machine to work without stopping.
