Technical Field
[0001] This utility model relates to the field of ferrochrome production, and specifically relates to a rotary iron selection device. Background Art
[0002] During the production process of low-carbon ferrochrome, after tapping, the smelting slag floating on the surface of the ladle needs to be poured into the water quenching pool for water quenching, while retaining the low-carbon ferrochrome in the ladle. However, during the slag pouring process, it is inevitable to pour out a part of the finished low-carbon ferrochrome, resulting in the loss of finished iron. Content of the Utility Model

The front part of the bottom of the material selection pipe is fixedly connected to a feeding bin. The bottom of the feeding bin slopes forward and downward. The front end of the feeding bin is fixedly connected to an iron tapping pipe, and the top end of the iron tapping pipe is fixedly connected to the material selection pipe. The front side of the top of the material selection pipe is fixedly connected to a feeding hopper. The middle part of the top of the material selection pipe is fixedly connected to a slag discharging pipe, and the outer edge of the top of the slag discharging pipe expands outward. The rear end of the top of the material selection pipe is fixedly connected to a water adding pipe. Valves are installed on both the water adding pipe and the iron tapping pipe. There is a rotating shaft inside the material selection pipe, and the front and rear ends of the rotating shaft are respectively rotatably connected to the inner walls of the front and rear ends of the material selection pipe. Two cutter blades are fixedly connected to the outer wall of the rotating shaft. The cutter blades are spiral, and the thread directions of the two cutter blades are opposite. The two cutter blades are symmetrically arranged front and back. A motor is fixedly installed at the front end of the material selection pipe. The front end of the rotating shaft penetrates through the inner wall of the front end of the material selection pipe, and the output shaft of the motor is fixedly connected to the front end of the rotating shaft.
[0006] Both the bottom of the motor and the outer wall of the rear end of the material selection pipe are fixedly connected to a support frame. The support frame is in a "冂" shape, and the bottom of the support frame is rotatably connected to a moving wheel.
[0007] Advantages of this utility model:
[0008] Through the rotation of the cutter blades and the push of water, this utility model utilizes the density difference between ferrochrome slag and finished iron to effectively separate the ferrochrome slag from the finished iron. The separation process is efficient and fast, improving the production efficiency. The separation process can be completed only by adding materials through the feeding hopper, opening the valve of the water adding pipe, and starting the motor. Description of the Drawings

Specific implementation mode
[0015] As Figure 1-5 shown: A rotary iron selection device includes a material selection pipe 1, the material selection pipe 1 extends forward and backward, the front part of the bottom of the material selection pipe 1 is fixedly connected and communicated with a blanking bin 2, the bottom of the blanking bin 2 slopes forward and downward, the front end of the blanking bin 2 is fixedly connected and communicated with an iron discharge pipe 3, the top end of the iron discharge pipe 3 is fixedly connected with the material selection pipe 1, the front side of the top of the material selection pipe 1 is fixedly connected and communicated with a feeding hopper 4, the middle part of the top of the material selection pipe 1 is fixedly connected and communicated with a slag discharge pipe 5, the outer edge of the top of the slag discharge pipe 5 expands outward, the rear end of the top of the material selection pipe 1 is fixedly connected and communicated with a water adding pipe 6, valves are installed on both the water adding pipe 6 and the iron discharge pipe 3, a rotating shaft 7 is provided in the material selection pipe 1, the front and rear ends of the rotating shaft 7 are respectively rotationally connected with the inner walls of the front and rear ends of the material selection pipe 1, two reamers 8 are fixedly connected to the outer wall of the rotating shaft 7, the reamers 8 are spiral, the two reamers 8 are symmetric front and back, and the thread directions of the two reamers 8 are opposite, a motor 9 is fixedly installed at the front end of the material selection pipe 1, the front end of the rotating shaft 7 penetrates through the inner wall of the front end of the material selection pipe 1, and the output shaft of the motor 9 is fixedly connected with the front end of the rotating shaft 7.
[0016] Both the bottom of the motor 9 and the outer wall of the rear end of the material selection pipe 1 are fixedly connected with a support frame 10, the support frame 10 is in a 冂 shape, and the bottom of the support frame 10 is rotationally connected with a moving wheel 11.
[0017] The moving wheel 11 facilitates the user to move the device to the required position.
[0018] First, add the water-quenched low-carbon ferrochrome slag into the material selection pipe 1 through the feeding hopper 4.
[0019] Then, open the valve of the water adding pipe 6 and inject an appropriate amount of water into the material selection pipe 1 until the material selection pipe 1 is filled with water.
[0020] Start the motor 9, the output shaft of the motor 9 starts to rotate, and drives the rotating shaft 7 to rotate in the material selection pipe 1.
[0021] The rotation of the rotating shaft 7 drives the two spiral reamers 8 to rotate in the material selection tube 1. Since the two reamers 8 are symmetrical, a thrust toward the middle is generated when the two reamers 8 rotate.
[0022] Since the density of ferrochrome slag is low and it is relatively light, the rotation of the reamer 8 will push the slag to the middle of the material selection pipe 1. The slag will gradually overflow from the slag discharge pipe 5 as it rotates and is pushed by water.
[0023] At the same time, the finished iron with a higher density will settle to the bottom of the lower silo 2 due to its heavy weight, and the finished iron will sink into the iron outlet pipe 3 along the inclined bottom of the lower silo 2.
[0024] When the separation process is completed, the motor 9 is turned off and the valve of the iron outlet pipe 3 is opened. The finished iron deposited in the iron outlet pipe 3 can flow out through the valve, thereby completing the material removal process.
