Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0016] In the prior art, the slag separation operation after the cooling and demolding of the tungsten-iron alloy mainly relies on manual operation, which is not only low in efficiency, but also increases the labor intensity of the operators. Meanwhile, there are potential safety hazards in the manual separation process, and the separation effect is greatly affected by human factors, resulting in unstable product quality.

[0017] Therefore, the present application provides a slag-iron separation slide device suitable for smelting tungsten-iron by iron extraction method. Through the cooperation between the vertical slide, the inclined slide, the Teflon pad, the slag outlet, the roller, the protrusion, the blowing port, the dispersion pipe, the electromagnetic pulse valve, the slag collection hopper, the alloy collection hopper and the photoelectric sensor, the tungsten-iron alloy block after cooling and demolding is put into the slag-iron separation slide device. The surface of the tungsten-iron alloy block in the falling process is blown by high-pressure airflow, and the surface of the tungsten-iron alloy block is impacted by the roller and the protrusion during the movement of the tungsten-iron alloy block. The slag on the surface of the tungsten-iron alloy block is quickly separated from the alloy block under the double action of blowing and impact, and the slag and the alloy block are collected respectively. Thus, the slag on the surface of the tungsten-iron alloy block is efficiently and automatically separated, the separation effect of the slag, the production efficiency and the product quality are improved, the labor intensity of the workers is reduced, and the safety in the production process is improved.

[0018] Through the personnel in the art, all electrical components in the case are connected to their adapted power supply through wires, and appropriate controllers and encoders should be selected according to actual conditions to meet the control requirements. The specific connection and control sequence should be completed according to the working order between the electrical components in the following working principle. The detailed connection means is a well-known technology in the art. The working principle and process are mainly introduced below, and the electrical control is not described.

[0019] From Figures 1-3 It is known that a slag-iron separation chute device suitable for smelting tungsten-iron by iron extraction method, comprising a vertical chute 1, the bottom side of the vertical chute 1 is communicated with an inclined chute 2, the inner wall of the inclined chute 2 is provided with a Teflon pad 3 below the vertical chute 1, the inner wall bottom of the inclined chute 2 is provided with a slag falling port 4, the inside of the slag falling port 4 is rotatably connected with a roller shaft 5 at equal intervals, the outer wall of the roller shaft 5 is provided with a protrusion 6 at equal intervals, the top end outer wall of the vertical chute 1 is installed with a photoelectric sensor 22, the outer wall of the vertical chute 1 is provided with a blowing port 7 at equal intervals, the outer wall of the vertical chute 1 located at the blowing port 7 is provided with a dispersion pipe 8, the two sides of the dispersion pipe 8 are both installed with an electromagnetic pulse valve 9, the slag falling port 4 is provided below with a slag collecting hopper 10, the slag collecting hopper 10 collects the separated slag below the slag falling port 4, which is convenient for subsequent processing and utilization, the end of the inclined chute 2 is provided below with an alloy collecting hopper 11, the alloy collecting hopper 11 is used to collect the pure tungsten-iron alloy block after slag-iron separation, so as to facilitate subsequent processing;

[0020] In the implementation process, it is particularly worth pointing out that through the cooperation between the vertical chute 1, the inclined chute 2, the Teflon pad 3, the slag outlet 4 and the roller 5, the ferrotungsten block enters the inside of the vertical chute 1 after cooling and demolding, and moves downward under the action of gravity. When the ferrotungsten block contacts the Teflon pad 3, the Teflon pad 3 reduces the impact caused by the sliding of the ferrotungsten material through its good lubrication and wear resistance, reduces noise, and slides along the Teflon pad 3 to the roller 5. During the movement of the ferrotungsten block, the roller 5 and the protrusion 6 form an impact on the surface of the ferrotungsten block. The slag on the surface of the ferrotungsten block gradually separates from the alloy block under the action of the impact force and enters below the slag outlet 4. The ferrotungsten block enters the collecting device from the end of the inclined chute 2, realizing automatic separation of the slag on the surface of the ferrotungsten block. Through the cooperation between the vertical chute 1, the blowing port 7, the dispersion pipe 8, the electromagnetic pulse valve 9 and the photoelectric sensor 22, after the ferrotungsten block enters the vertical chute 1, the photoelectric sensor 22 is triggered. The photoelectric sensor 22 transmits a signal to the control system, and the control system automatically controls the electromagnetic pulse valve 9 to open, so that high-pressure gas enters the blowing port 7 through the dispersion pipe 8. The surface of the ferrotungsten block in the falling process is blown by the high-pressure gas flow, further promoting the separation of the slag and the alloy block. At the same time, the high-pressure gas blown can also clean the inside of the vertical chute 1 to prevent clogging caused by slag accumulation. The slag collecting hopper 10 collects the separated slag below the slag outlet 4, facilitating subsequent processing and utilization. The alloy collecting hopper 11 is used to collect the pure ferrotungsten alloy block after the slag-iron separation, so as to facilitate subsequent processing. Through the cooperation between the vertical chute 1, the inclined chute 2, the Teflon pad 3, the slag outlet 4, the roller 5, the protrusion 6, the blowing port 7, the dispersion pipe 8, the electromagnetic pulse valve 9, the slag collecting hopper 10, the alloy collecting hopper 11 and the photoelectric sensor 22, by putting the ferrotungsten block after cooling and demolding into the slag-iron separation chute device, the surface of the ferrotungsten block in the falling process is blown by the high-pressure gas flow, and during the movement of the ferrotungsten block, the roller 5 and the protrusion 6 form an impact on the surface of the ferrotungsten block. The slag on the surface of the ferrotungsten block is rapidly separated from the alloy block under the double action of blowing and impact, and the slag and the alloy block are collected respectively, so as to realize efficient and automatic separation of the slag on the surface of the ferrotungsten block, improve the separation effect of the slag, the production efficiency and the product quality, and reduce the labor intensity of workers, improve the safety in the production process.
