[0022] In this embodiment, Figure 1 and Figure 4 As shown, the driving pulley 3 is connected to the driven pulley 4 by a belt, and the driving pulley 3 and the driven pulley 4 form a rotating structure through the servo motor 2, and the rocker 5 moves in a circular motion along the surface of the driven pulley 4, and at the same time, the screening barrel 6 is in a reciprocating transmission structure in the middle of the frame 1 through the rocker 5 and the movable bracket 7; when the servo motor 2 drives the driving pulley 3 to rotate, the driven pulley 4 rotates under the action of the belt, so that the rocker 5 rotates in a circular motion on its surface accordingly with its rotation, thereby achieving the purpose of promoting the transmission of the screening barrel 6 welded at its tail end, and the screening barrel 6 is in a movable structure in the middle of the frame 1 through the movable bracket 7, and the structure of the front end rocker 5 is used to achieve the purpose of pushing it back and forth, so that the raw materials placed inside it are screened under the reciprocating motion structure, and impurities mixed in the raw materials are stripped away.

[0023] In this embodiment, Figure 1 and Figure 2 As shown, a tension spring 11 is welded to one side of the outer wall of the screening barrel 6 through a mounting frame, and one end of the tension spring 11 is installed and connected to one side of the frame 1, and the tension spring 11 forms an elastic telescopic structure through the screening barrel 6 and the movable bracket 7; the screening barrel 6 has a certain weight when loading raw materials, and when the screening barrel 6 is driven and reciprocated by the front driving pulley 3 and the driven pulley 4, its tail end is connected to the frame 1 through the tension spring 11, which ensures the support and stability of the screening barrel 6 during the movement, and the screening barrel 6 will generate a certain vibration when it is reciprocated. At the same time, when the screening barrel 6 is pushed forward, the tension spring 11 is elastically deformed by force. Due to its large elastic coefficient, it generates an equal reaction force when resetting. Under the impetus of this reaction force, the power of the reciprocating motion of the screening barrel 6 is increased, and this relative motion force is used to further improve the screening efficiency.

[0024] In this embodiment, Figure 3 As shown, the screening barrel 6 is made of metal and is rotatably connected to a sealing cover at the top through a lock provided on the outer wall, and the filter chassis 8 is embedded and plugged into the bottom of the screening barrel 6 through a trapezoidal protrusion provided on its surface, and the surface of the filter chassis 8 is a hollow panel with a cavity at the bottom, and the filter chassis 8 is located below the diversion port 9; the opening and closing structure of the screening barrel 6 facilitates the delivery of raw materials and ensures the internal sealing during reciprocating screening, greatly reducing the problem of dust spreading during the screening process, and when the raw materials are pushed back and forth inside the screening barrel 6, the internal impurities are peeled off and merged into the internal cavity of the filter chassis 8. After the raw material screening is completed, the separate structure of the filter chassis 8 facilitates the cleaning of internal impurities.

[0025] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the diverter ports 9 are distributed in a ring shape on the inner wall of the screening barrel 6, and the aperture specifications of the diverter ports 9 are different; the diverter ports 9 are set to have apertures of different specifications so that the raw materials inside the screening barrel 6 can be collected into the external collecting box 10 through the diverter ports 9 of the same aperture according to their own specifications during the reciprocating swing process. While filtering the impurities inside the raw materials, the screening barrel 6 uses the structure of the diverter ports 9 to complete the diversion and screening purpose according to the different specifications of the raw materials. Since the processing and smelting methods of raw materials of different sizes are different, the purpose of classified processing is achieved, thereby improving the overall production efficiency and ferrosilicon quality.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3As shown, the aggregate box 10 is made of metal, and is connected to the screening barrel 6 through the diversion port 9, and the aggregate box 10 is rotatably connected to a movable door at the bottom through a lock opened on its outer wall; the aggregate box 10 is used to classify and store raw materials of different specifications, and the opening and closing structure at the bottom facilitates the collection of internal materials.

[0027] The use method and advantages of the utility model: When the raw material screening device with a filtering structure is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the filter chassis 8 is embedded and inserted into the inside of the screening barrel 6, and the raw materials containing impurities are put into the inside of the screening barrel 6 again. The raw materials will be loaded on the surface of the filter chassis 8, and the sealing cover on the top of the screening barrel 6 is closed, and the barrel body and the top cover are locked with the lock provided on the outside. When the power servo motor 2 is started to drive the active pulley 3 to rotate, the driven pulley 4 rotates under the action of the belt so that the rocker 5 rotates in a circle on its surface accordingly with the rotation of the rocker 5. When the rocker 5 moves, the screening barrel 6 welded at its tail end will drive the movable bracket 7 to slide back and forth in the slide grooves at both ends of the inner wall of the frame 1, and when the screening barrel 6 is pushed to the front end, the tension spring 11 is elastically deformed by force, and the tension spring 11 produces the same reaction when it is reset. The relative kinetic force increases the reciprocating motion of the screening barrel 6, and the screening efficiency is further improved by using the relative kinetic force, while the support and stability of the screening barrel 6 during the screening process are increased. When the raw materials are pushed back and forth inside the screening barrel 6, the impurities mixed inside are stripped off and flow into the internal cavity of the filter chassis 8. During the reciprocating swinging process, the corresponding raw materials flow into the external collecting box 10 through the diversion port 9 of the same aperture according to their own specifications, until all the raw materials are filtered and screened, the power is turned off, and the lock on the outer wall of the collecting box 10 is used to open the movable door below for collection one by one. At the same time, the sealing cover of the screening barrel 6 is opened, the filter chassis 8 is taken out, and the impurities remaining in its cavity are dumped.
