Description

Technical Field

[0001] The utility model relates to the technical field of ferrous metal casting, in particular to a melting furnace for ferrous metal casting. Background Art

[0002] Nonferrous metals mainly refer to iron and its alloys, such as steel, pig iron, iron alloys, cast iron, etc. When casting ferrous metals, the metal needs to be put into a melting furnace to melt first, and then the molten metal liquid is poured into a casting mold to cool and shape. However, the existing industrial metal melting furnaces are large in size and have a heavy furnace cover on the top. It is quite laborious to open it only by manpower, which brings inconvenience to the use of the melting furnace.

[0003] As disclosed in Chinese patent announcement number CN212620064U, a melting furnace for metal parts processing and casting is disclosed. When in use, the stepper motor is electrically connected to the controller through a wire. When in use, the controller controls the stepper motor to rotate forward, the stepper motor drives the bevel gear to rotate through the rotating shaft, the bevel gear drives the rotating rod to rotate through the bevel gear, and the rotating rod drives the winding wheel to rotate, so that the winding wheel winds the pull rope, and then the pull rope pulls the furnace cover to move through the connecting rod, so that the furnace cover is rotated and opened. When the furnace cover is rotated to vertical, the limit hook is inserted into the inner side of the limit frame, and then the furnace cover is fixed and limited, so that compared with the existing melting furnace for metal parts processing and casting, this device, in the actual use process, through the mechanical structure and electric drive, the heavy furnace cover can be easily opened, which greatly facilitates the opening of the furnace cover and provides convenience for the use of the melting furnace. The controller controls the stepper motor to reverse, and then rotates the limit hook to remove the limit hook from the inner side of the limit frame, and then the furnace cover can be rotated back to its original position.

[0004] However, the melting furnace for metal parts processing and casting in the above application has certain limitations because of the uneven heating due to the accumulation of metal when heating and melting the metal in the furnace. When the outer metal melts, the inner metal remains unmelted.

[0005] For this reason, we are in urgent need of providing a melting furnace for ferrous metal casting. Utility Model Content

[0006] The utility model aims to provide a melting furnace for ferrous metal casting, so as to solve the problem that when the metal in the furnace is heated and melted, the metal is piled up and heated unevenly, and when the outer layer of metal is melted, the metal inside is still not melted.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a melting furnace for ferrous metal casting, comprising a melting furnace and a crushing box, wherein the crushing box is installed on the right side of the melting furnace, a rotating device is arranged outside the melting furnace, and a crushing device is arranged inside the crushing box.

[0008] The rotating device includes a rotating wheel, a bearing seat, a rotating shaft, and a roller. The two rotating wheels are respectively fixedly connected to the left and right sides of the outer surface of the melting furnace, the two bearing seats are respectively installed on the left and right sides of the front end of the melting furnace, the rotating shaft is rotatably connected to the inside of the bearing seat, and the two rollers are respectively fixedly connected to the left and right sides of the outer surface of the rotating shaft, and are respectively rotatably connected to the inside of the rotating wheel.

[0009] A further improvement is that there are two groups of rotating devices, which are symmetrically installed at the front and rear ends of the melting furnace respectively. A driving motor is installed on the left bearing seat of the front rotating device, and the left end of the rotating shaft is connected to the output end of the driving motor. Starting the driving motor drives the rotating shaft to rotate inside the bearing seat, thereby driving the roller on the rotating shaft to rotate inside the rotating wheel, thereby driving the rotating wheel to rotate, and then driving the melting furnace to rotate, so that the molten metal inside it rotates, so that the metal inside and outside is flipped, and it is fully heated and melted.

[0010] A further improvement is that the interior of the melting furnace is provided with four installation chambers in a ring shape, and electric heating plates are respectively installed inside the four installation chambers. The electric heating plates are started to heat the interior of the melting furnace, thereby melting the metal inside into molten metal.

[0011] A further improvement is that a sealed furnace door is installed at the left end of the melting furnace, a feed pipe is fixedly connected to the middle of the right outer surface of the melting furnace, and an electric sealing valve is installed on the outer surface of the feed pipe. Metal is added into the interior of the melting furnace through the feed pipe, and the feed pipe is sealed by the electric sealing valve to prevent the molten metal from leaking through the feed pipe.

[0012] A further improvement is that the crushing device includes a crushing motor, a transmission member, a crushing knife group, and a side wall knife group. The crushing motor is installed on the back of the crushing box, and the two groups of transmission members are respectively installed on the left and right sides of the inside of the crushing box, and the rear end of the right transmission member is connected to the crushing motor. The two groups of crushing knife groups are respectively installed on the outer surface of the transmission member, and the two groups of side wall knife groups are respectively fixedly connected to the left and right inner walls of the crushing box. Starting the crushing motor drives the rotating shaft in the transmission member to rotate, and then drives the meshing gears at the rear end of the rotating shaft to mesh and rotate with each other, thereby driving the crushing knife groups on the two rotating shafts to rotate to crush the metal, which is more conducive to its melting and improves the melting efficiency.

[0013] A further improvement is that a feed hopper is fixedly connected to the top of the crushing box, and a discharge pipe is fixedly connected to the bottom center of the crushing box, and the metal is poured into the interior of the crushing box through the feed hopper.

[0014] A further improvement is that an electric sealing valve is also installed on the outer surface of the discharge pipe, and its left end is connected to the feed pipe. The discharge pipe is connected to the feed pipe, and then the electric sealing valves on the two are opened, so that the crushed metal particles can be discharged into the interior of the melting furnace. After the metal particles are discharged, the two are separated and the electric sealing valve is closed.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The ferrous metal casting melting furnace starts the crushing motor to drive the rotating shaft in the transmission part to rotate, and then drives the meshing gears at the rear end of the rotating shaft to mesh and rotate with each other, thereby driving the crushing knife groups on the two rotating shafts to rotate to crush the metal, which is more conducive to its melting and improves the melting efficiency.
