[0002] When traditional cutting machine tools are used to cut or grind various parts, a lot of machining debris is often left on the cutting table of the machine tool. In order to respond to sustainable development practices, most machine tools are equipped with debris collectors to collect and recycle the debris from the machined parts.

[0003] Traditional metal scrap processing has a low degree of automation, incomplete impurity separation, and difficulty in achieving efficient separation of ferrous and non-ferrous metals, resulting in low resource utilization.

[0004] Therefore, those skilled in the art urgently need to develop a metal scrap recycling device for the production of thick metal castings. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a metal scrap recycling device for the production of thick metal castings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a metal scrap recycling device for the production of thick metal castings, comprising a recycling tank, a feeding hopper at the top of the recycling tank, and a first screen plate, a second screen plate and a guide plate arranged sequentially from top to bottom inside the recycling tank;

Impurities are circulated and screened by a screw conveyor via a diversion pipe. A scraper-assisted metal scraps are conveyed to a conveyor via a guide plate and a discharge hopper, connecting to the magnetic separation process. The entire system forms a closed loop of "screening-conveying-sorting-recycling," achieving automation and high efficiency in metal waste treatment.

[0024] Please see Figures 1-2 This utility model provides an embodiment: a metal scrap recycling device for the production of thick metal castings, including a recycling tank 1, a feeding hopper 2 on the top of the recycling tank 1, and a first screen plate 3, a second screen plate 4 and a guide plate 7 arranged sequentially from top to bottom inside the recycling tank 1;

[0025] The first sieve plate 3 is inclined to the lower left, and the inclination angle of the first sieve plate 3 is 15°-30°. The right end of the first sieve plate 3 is rotatably connected to the inner wall of the recycling tank 1. A vibration component is provided at the lower left of the first sieve plate 3. A first diversion pipe 17 is provided on the left side of the inner wall of the recycling tank 1 corresponding to the position of the first sieve plate 3.

[0026] The second screen plate 4 is horizontally set and fixedly connected to the inner wall of the recycling tank 1. The screen mesh of the second screen plate 4 is distributed around its perimeter. The first motor 5 is provided at the bottom center of the second screen plate 4. The output end of the first motor 5 extends out of the second screen plate 4 and is connected to the scraper shaft. The scraper shaft is provided with a scraper 6. The second diversion pipe 18 is provided on the left side of the inner wall of the recycling tank 1 corresponding to the position of the second screen plate 4.

[0027] The guide plate 7 is inclined to the lower right and is fixedly connected to the inner wall of the recycling tank 1. The discharge hopper 9 is provided on the right side of the inner wall of the recycling tank 1 corresponding to the position of the guide plate 7. The bottom of the guide plate 7 is provided with a vibration motor 8.

[0028] A vertically placed screw feeder 15 is provided at the left end of the recycling tank 1. The recycling tank 1 is connected to the screw feeder 15 through the first diversion pipe 17 and the second diversion pipe 18. A recycling pipe 20 is connected to the top right side of the screw feeder 15. The recycling pipe 20 is located above the feed hopper 2.

[0029] Furthermore, the first diversion pipe 17 and the second diversion pipe 18 are inclined to the lower left, and the top left side of the screw feeder 15 is connected to the waste pipe 19. The screw feeder 15 is equipped with a rotating feeding screw 16 inside, and the top of the screw feeder 15 is equipped with a drive motor to drive the feeding screw 16 to rotate.

[0030] The inclined arrangement of the first diversion pipe 17 and the second diversion pipe 18 facilitates the rapid flow of screened impurities into the screw feeder 15, while preventing backflow of materials inside the screw feeder 15. Furthermore, the first diversion pipe 17, the second diversion pipe 18, and the waste pipe 19 are all equipped with control valves. Screened impurities can be re-injected into the feed hopper 2 for screening via the recovery pipe 20, while the waste pipe 19 can directly discharge impurities. The corresponding valves can be switched on and off as needed. A cleaning port (not shown in the figure) is provided on the bottom side wall of the screw feeder 15 for later maintenance.

[0031] Furthermore, the vibration assembly includes a cam 22 located on the lower left of the first screen plate 3, and a second motor 21 connected to the outer wall of the recycling tank 1. The output end of the second motor 21 extends to the recycling tank 1 and is connected to the cam 22.

[0032] The second motor 21 controls the cam 22 to rotate up and down. The cam 22 intermittently lifts the lower left side of the first screen plate 3 to achieve vibration screening. The left end of the first screen plate 3 extends into the first diversion pipe 17.

[0033] The width of the first diversion pipe 17 can be optimized based on the up-and-down swing amplitude of the first sieve plate 3 to avoid interference with the inner wall.

[0034] Furthermore, a conveyor 10 is provided below the discharge hopper 9. A frame 14 is connected to the bottom of the discharge hopper 9 and the recycling tank 1. The conveyor 10 includes a frame, and a high magnetic roller and a drive wheel are respectively rotatably provided on the left and right sides of the frame. A third motor 11 is connected to the frame to control the rotation of the drive wheel. A conveyor belt is provided between the high magnetic roller and the drive wheel. A first receiving box 12 is provided on the lower left side of the high magnetic roller, and a second receiving box 13 is provided on the lower right side of the high magnetic roller.

[0035] The third motor 11 drives the drive wheel to rotate, thereby making the conveyor belt rotate counterclockwise. The screened metal scraps pass through the high magnetic roller. After the iron scraps are attracted, the other metals fall into the first receiving box 12 by inertia. After the iron scraps pass through the high magnetic roller, they fall into the second receiving box 13.

[0036] The working principle of this utility model is as follows: When in use, metal scraps are fed into the recycling tank 1 through the feed hopper 2. The first screen plate 3 vibrates to perform coarse screening, screening out large particles of wood chips and other impurities. The impurities flow into the screw feeder 15 through the first diversion pipe 17. The metal scraps fall into the second screen plate 4 after passing through the first screen plate 3. The first motor 5 drives the scraper 6 to rotate, and the metal scraps fall into the guide plate 7 through the second screen plate 4, and then into the conveyor 10 through the discharge hopper 9. The impurities flow into the screw feeder 15 through the second diversion pipe 18. The screw feeder 15 carries the impurities to the recycling pipe 20, and then feeds them back into the feed hopper 2 for screening. The screened metal scraps pass through the high magnetic roller. After the iron filings are attracted, the other metals fall into the first collection box 12 by inertia. After passing through the high magnetic roller, the iron filings fall into the second collection box 13.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
