Description

Technical Field

[0001] This utility model belongs to the technical field of metal separation equipment, and specifically relates to an improved metal separator. Background Technology

[0002] In metal processing, such as cast iron or steel processing, after processing is completed, it is necessary to separate the slag from the solid material so that they can proceed to the next production step. Traditional slag-iron separation and screening methods mostly rely on manual or simple mechanical operations, which are not only inefficient and labor-intensive, but also often fail to achieve the desired separation and screening results.

[0003] Currently, mechanical slag and iron separation equipment has appeared on the market, including vertical and horizontal structures. During use, the working principle of this type of equipment is to drive a high-speed rotating hammer to strike the material, thereby separating the slag from the object. The technical problem encountered is that when fixing the hammers, the hammer fixing plates are connected in series by a connecting rod and then locked at the end. This structure fixes several hammers, but during actual assembly, the hammer fixing plates often slide axially on the connecting rod. In addition, keyways need to be machined on the shaft to achieve assembly, which increases the assembly process and the unit price.

[0004] In view of the shortcomings of the existing technology and the numerous problems existing in such equipment, it is very necessary for technical R&D personnel in this industry to make structural improvements on the existing basis. By improving the fixing structure of the hammer, we can solve the many technical problems existing in the current metal separator. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this utility model provides an improved metal separator with a novel design. By designing a polygonal shaft, the hammer fixing plate can be directly formed by cutting, and then quickly assembled, which can improve assembly and maintenance efficiency and reduce the layout cost of important components.

[0006] To achieve the above technical objectives, the present invention adopts the following solution: an improved metal separator, comprising a frame, a feed inlet on the frame, a striking unit at the lower part of the feed inlet, a polygonal shaft mounted on the striking unit via a bearing seat, a fixed plate fixed on the polygonal shaft, a polygonal hole on the fixed plate to mate with the polygonal shaft, a plurality of fixed rods on the fixed plate to fix the hammer, and a protective sleeve between adjacent fixed plates to protect the polygonal shaft and provide axial positioning.

[0007] A vibrating screen is provided below the striking unit, a lower lifting frame is provided on the side of the vibrating screen, an upper lifting frame is provided on the frame, a spring is provided between the upper and lower lifting frames, and a centrifugal block is also provided on the vibrating screen.

[0008] The feed inlet is equipped with a material drop protection curtain, which consists of multiple pieces and is located at the connection between the feed inlet and the striking unit.

[0009] An external baffle is also provided on the outside of the feed inlet. The external baffle is inclined and inserted into the inside of the striking unit to prevent material backflow.

[0010] The hammer includes a connecting part and a striking part. The joint between the striking part and the connecting part is a right-angle transition. This structure effectively increases the collision force between the material and the hammer.

[0011] The striking unit is provided with a support base on the outside, and a cover is provided on the support base. A side protective plate is provided inside the cover. The side protective plate is fixed on the cover to isolate the cover from the material.

[0012] The beneficial effects of this utility model are as follows: This utility model features a polygonal shaft mounted within the striking unit via a bearing seat. A fixed plate is fixed to the polygonal shaft, and the fixed plate has polygonal holes that mate with the polygonal shaft. Several fixed rods are mounted on the fixed plate to secure the hammer. Protective sleeves are installed between adjacent fixed plates to protect the polygonal shaft and provide axial positioning. This structure is simple and easy to assemble, disassemble, and maintain. A vibrating screen is located below the striking unit, with a lower lifting frame on the side of the vibrating screen and an upper lifting frame on the frame. A spring is installed between the upper and lower lifting frames. This structure improves the assembly efficiency of the vibrating screen and enables rapid screen replacement.

[0019] The present invention will be described in detail below through specific embodiments. However, it should be noted that the specific embodiments described below do not limit the technical solution. Those skilled in the art can make further technical extensions under the guidance of the specific technical solutions described below.

[0020] Example 1: Referring to the figure, an improved metal separator adopts a horizontal structure, including a frame 1, on which a feed inlet 11 is provided, and a striking unit 3 is provided at the lower part of the feed inlet 11. A polygonal shaft 31 is mounted in the striking unit 3 through a bearing seat. In this embodiment, the polygonal shaft 31 is a hexagonal shaft. This hexagonal shaft can be directly cut from a profile, which is made of high-strength steel.

[0021] A fixing plate 34 is fixed on the hexagonal shaft. The fixing plate 34 has polygonal holes that mate with the polygonal shaft. These polygonal holes can be directly machined by wire cutting. Several fixing rods 36 are provided on the fixing plate 34 to fix the hammer. Protective sleeves 32 are provided between adjacent fixing plates 34. The protective sleeves 32 are fitted onto the polygonal shaft 31 to protect the polygonal shaft 31 and provide axial positioning. This structure is easy to manufacture and assemble. Since the hammer is a consumable part that needs to be replaced periodically, this structure makes it even easier to replace the hammer.

[0022] This invention also includes a vibrating screen 2 located below the striking unit 3. A lower lifting frame 20 is provided on the side of the vibrating screen 2. In this embodiment, there are four lower lifting frames 20, with corresponding upper lifting frames on the frame body 1. Fixing holes are provided on both the upper and lower lifting frames 20. A spring 4 is installed between the upper and lower lifting frames 20. This structure allows for easy disassembly. By using the lifting frames to position the spring 4 outside the vibrating screen 2 without contacting it, vibration can prevent the spring 4 from being compressed and affecting the release of its elastic force. A centrifugal block 24 is also provided on the vibrating screen 2. This design increases the amplitude of the vibrating screen 2 without affecting the normal operation of the spring 4.

[0023] When this utility model is in operation, the striking unit 3 is connected to the motor I 15 at the top of the frame 1, and the vibrating screen 2 is connected to the motor II 16. The motor I 15 at the top drives the striking unit 3 to work, and the motor II 16 drives the vibrating screen 2 to run. The vibrating screen 2 adopts a three-layer structure, with a double-layer screen inside and three levels of discharge ports, namely the bottom discharge port 21, the middle discharge port 22, and the high discharge port 23. The discharge of materials of different fineness is realized through the three levels of discharge ports.

[0024] The key design feature of this utility model is that a material drop protection curtain 18 is provided on the feed inlet 11. The material drop protection curtain 18 consists of multiple pieces and is hinged at the top of the feed inlet 11 at the connection between the feed inlet 11 and the striking unit 3. It can effectively limit the flow of material when it falls and prevent a large flow of material from entering the striking unit 3 and causing jamming.

[0025] An external baffle 17 is also provided on the outside of the feed inlet 11. The external baffle 17 is inclined between the feed inlet 11 and the striking unit 3 and is inserted into the striking unit. Its purpose is to work with the material drop protection curtain 18 to prevent the debris from splashing back and causing damage to external personnel or equipment when the material is struck.

[0026] Furthermore, the hammer disclosed in this utility model includes a connecting part 37 and a striking part 38. The striking part 38 and the connecting part 37 are joined by a right-angle transition. This structure increases the edge and straight surface structure, effectively improving the collision force between the material and the hammer. After actual verification, this structure is 10% more efficient than the current arc transition structure. After selecting manganese steel to make the hammer, its stability is also greatly improved.

[0027] Furthermore, the striking unit 3 is provided with a support base 14 on the outside, and a cover 12 is bolted to the support base 14. A side protective plate 33 is provided inside the cover 12. The side protective plate 33 is fixed to the cover 12 to isolate the cover 12 from the material. Since the cover 12 is only used for side protection and its thickness is limited, the side protective plate 33 is used to achieve internal protection in order to avoid the material from damaging the cover.

[0028] The above structure is simple and easy to assemble, disassemble and maintain. A vibrating screen 2 is set below the striking unit 3. A lower lifting frame 20 is set on the side of the vibrating screen 2. An upper lifting frame is set on the frame 1. A spring 4 is set between the upper lifting frame and the lower lifting frame. This structure improves the assembly efficiency of the vibrating screen 2 and enables quick replacement of the screen.
