Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a waste concrete separation device for concrete processing. Background Technology

[0002] A large amount of waste concrete is generated when constructing new buildings or demolishing old ones. In the past, the main method of disposal was to transport this waste concrete to the suburbs for dumping or burial. However, this not only occupies land but also causes environmental pollution. In order to improve the environmental pollution caused by the disposal of waste concrete, it can be recycled by preparing recycled concrete. Currently, after the waste concrete is crushed, it is usually necessary to screen the crushed concrete to separate it into aggregates of different particle sizes for subsequent use.

[0003] However, existing separation equipment often fails to effectively separate and remove small amounts of metal parts such as iron nails, iron wires, or steel bars during the screening and separation process of crushed waste concrete. This results in aggregates containing metal parts entering downstream processes, causing equipment damage and negatively impacting the quality of subsequent concrete production. Utility Model Content

[0004] The purpose of this utility model is to provide a waste concrete separation device for concrete processing, which has the advantages of being able to screen and separate crushed waste concrete, and effectively remove the metal parts mixed in with it, so as to avoid the impact of metal parts on subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste concrete separation device for concrete processing, comprising a separation box, a screen plate movably connected to the middle of the inner cavity of the separation box, support springs fixedly connected to the four sides of the bottom of the screen plate, a hopper fixedly connected to the right end of the top of the separation box, a support frame fixedly connected to the top of the inner cavity of the separation box, an electromagnet fixedly installed at the bottom of the support frame, a fixed cover fixedly connected to the upper end of the front surface of the separation box, a drive motor fixedly installed at the right end of the bottom of the outer surface of the fixed cover, an adjusting screw fixedly installed at the output end of the drive motor, the top of the adjusting screw movably connected to the top of the inner cavity of the fixed cover via a bearing, a moving plate threadedly connected to the upper end of the adjusting screw, a push rod movably connected to the left end of the moving plate via a pin, a fixed rod movably connected to the lower end of the push rod via a pin, a rotating shaft fixedly connected to the left side of the fixed rod, the middle end of the rotating shaft movably connected to the upper end of the separation box via a bearing, and a guide frame fixedly connected to the back of the rotating shaft.

[0022] Example 1:

[0023] Please see Figures 1-4 As shown, this utility model provides a waste concrete separation device for concrete processing, including a separation box 1. A screen plate 12 is movably connected to the middle of the inner cavity of the separation box 1. Support springs 15 are fixedly connected to the four sides of the bottom of the screen plate 12. A hopper 7 is fixedly connected to the right end of the top of the separation box 1. A support frame 9 is fixedly connected to the top of the inner cavity of the separation box 1. An electromagnet 8 is fixedly installed at the bottom of the support frame 9. A fixed cover 2 is fixedly connected to the upper end of the front surface of the separation box 1. A drive motor 18 is fixedly installed at the right end of the bottom of the outer surface of the fixed cover 2. An adjusting screw 19 is fixedly installed at the output end of the drive motor 18. The top of the adjusting screw 19 is movably connected to the top of the inner cavity of the fixed cover 2 via a bearing. A moving plate 21 is threadedly connected to the upper end of the adjusting screw 19. A push rod 22 is movably connected to the left end of the moving plate 21 via a pin. A fixed rod 23 is movably connected to the lower end of the push rod 22 via a pin. A rotating shaft 17 is fixedly connected to the left side of the fixed rod 23. The middle end of the rotating shaft 17 is movably connected to the upper end of the separation box 1 via a bearing. A guide frame 6 is fixedly connected to the back of the rotating shaft 17.

[0024] In this technical solution, the hopper 7 facilitates the feeding of crushed waste concrete into the separation box 1. The guide frame 6 and screen plate 12 separate the waste concrete, allowing personnel to easily select aggregates of different particle sizes for use in subsequent concrete processing. Simultaneously, the electromagnet 8 magnetically attracts metal parts such as nails, wires, and short steel bars mixed in with the waste concrete rolling down from the guide frame 6, achieving separation and removal of these metal parts. This prevents metal contamination in the waste concrete from affecting subsequent production. Furthermore, the coordinated action of the drive motor 18, adjusting screw 19, moving plate 21, push rod 22, fixed rod 23, rotating shaft 17, and guide frame 6 facilitates the unloading of metal parts, greatly simplifying the work process.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-4As shown, a support frame 4 is fixedly connected to the middle of the right side of the outer surface of the separation box 1. A support rod 3 is fixedly connected to the bottom of the support frame 4 and the lower end of the right side of the outer surface of the separation box 1. A collection box 5 is placed in the inner cavity of the support frame 4. A mounting frame 10 is fixedly connected to the middle of the bottom of the screen plate 12. A vibration motor 11 is fixedly installed at the middle of the bottom of the mounting frame 10. A fixing block 13 is fixedly connected between the bottom of the support spring 15 and the lower end of the inner cavity of the separation box 1. A guide slide rod 14 is slidably connected to the right end of the fixing block 13. The top of the guide slide rod 14 is fixedly connected to the bottom of the screen plate 12. A limiting slide rod 20 is fixedly connected to the right side of the inner cavity of the fixing cover 2. The right end of the moving plate 21 is slidably connected to the surface of the limiting slide rod 20. A support shaft 16 is fixedly connected to the back of the guide frame 6. The back of the support shaft 16 is movably connected to the upper end of the inner cavity of the separation box 1 through a bearing. A first discharge port is opened at the lower end of the right side of the separation box 1, and a second discharge port is opened at the lower end of the left side of the separation box 1.

[0027] In this technical solution, the support frame 4 and support rod 3 support the collection box 5 and collect the metal parts falling from the guide frame 6 during the metal parts discharge process. The vibration motor 11 drives the screen plate 12 to vibrate rapidly during operation, effectively improving the screening and separation effect of the screen plate 12 on the crushed waste concrete. The guide slide rod 14 and fixing block 13 guide the screen plate 12 to prevent it from shifting. The limiting slide rod 20 guides the moving plate 21 to prevent it from rotating or tilting during movement. The support shaft 16 supports the back of the guide frame 6.

[0028] The working principle of this utility model is as follows: The hopper 7 allows personnel to easily feed crushed waste concrete into the separation box 1. The guide frame 6 guides the waste concrete to the left, allowing it to fall to the left end of the screen plate 12 and roll down the inclined surface of the screen plate 12 to the right. Simultaneously, the screen plate 12 separates the waste concrete, facilitating the selection of aggregates of different particle sizes during subsequent concrete processing. At the same time, the electromagnet 8 magnetically attracts metal components such as nails, wires, and reinforcing bars mixed in with the waste concrete rolling down above the guide frame 6, thus achieving the desired separation of metals. The separation and removal of metal parts prevents them from being mixed into the waste concrete and affecting subsequent production. After the separation is completed, the drive motor 18 is started to rotate the adjusting screw 19. The rotation of the adjusting screw 19 causes the moving plate 21 to move downward. The movement of the moving plate 21 can push the fixed rod 23, the rotating shaft 17 and the guide frame 6 to rotate via the push rod 22, causing the right side of the guide frame 6 to tilt downward. Then, by controlling the electromagnet 8 to stop working, the metal parts can fall without magnetic attraction and roll outward along the surface of the guide frame 6, which facilitates the discharge of metal parts and greatly facilitates the work of personnel.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
