Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 As shown, a novel screening device for decorative engineering comprises a base 1 arranged on one side of a crushing device, a conveyor belt 2 is fixed on the top of the base 1, a fixing frame 3 is bolted to one side of the top of the conveyor belt 2, an electromagnet 4 is arranged inside the fixing frame 3, and a lifting structure 5 for controlling the up and down movement of the electromagnet 4 is arranged above the electromagnet 4, a rotating rod 6 is rotatably connected to the lower part of the inner wall of the fixing frame 3, a first motor 7 is fixed below the front of the fixing frame 3, and the output shaft of the first motor 7 passes through the fixing frame 3 and is fixedly connected to the front end of the rotating rod 6, a stirring plate 8 is fixed on the surface of the rotating rod 6, a mounting frame 9 is fixed to the right side of the top of the base 1, and an eddy current magnetic separation roller 10 is installed above the mounting frame 9, a first recovery box 11 is arranged on the right side of the base 1, and a second recovery box 12 is placed on the right side of the first recovery box 11.

[0022] The lifting structure 5 includes a threaded rod 51, a second motor 52, a movable block 53 and a connecting rod 54. The threaded rod 51 is rotatably connected to the top of the inner wall of the fixed frame 3. The threads on the front and rear sides of the surface of the threaded rod 51 are arranged in opposite directions. The second motor 52 is fixed above the front side of the fixed frame 3, and the output shaft of the second motor 52 passes through the fixed frame 3 and is fixedly connected to the front end of the threaded rod 51. The movable block 53 is arranged on the front and rear sides of the surface of the threaded rod 51, and the movable block 53 is threadedly connected to the threaded rod 51. The connecting rod 54 is rotatably connected to the left and right sides of the movable block 53, and the other end of the connecting rod 54 is hinged to the top of the electromagnet 4. The connecting rod 54 is tilted as a whole. When the second motor 52 is turned on, the threaded rod 51 rotates, and the movable blocks 53 on the front and rear sides of the surface of the threaded rod 51 can move in opposite directions, thereby making the connecting rods 54 on both sides movable, and the electromagnet 4 below is driven to rise or fall through the connecting rods 54.

[0023] Limiting grooves 14 are provided on both the front and rear sides of the top of the inner wall of the fixed frame 3, and a limiting rod 13 is fixed on the top of the movable block 53. The top end of the limiting rod 13 extends to the inside of the limiting groove 14 and is bolted to the limiting block 15, and the limiting block 15 is slidably connected to the inner wall of the limiting groove 14. When the threaded rod 51 rotates, the upper limiting block 15 can limit the movable block 53 below, so that the movable block 53 can only move in the front and rear directions, so as to control the height of the electromagnet 4 below.

[0024] The stirring plate 8 is L-shaped as a whole, and is distributed in a ring shape on the four sides of the surface of the rotating rod 6. During the rotation of the rotating rod 6, the stirring plate 8 can stir the waste generated by the decoration project so that the metal in the waste can contact the electromagnet 4 above, so that the electromagnet 4 can recycle the metal iron.

[0025] A shielding plate 16 is fixed on the right side of the top of the second recycling box 12, and the shielding plate 16 is set at an angle. When non-ferrous metals fly out, the shielding plate 16 can shield the non-ferrous metals and guide them into the interior of the second recycling box 12 so that the staff can carry out subsequent recycling work.

[0026] The eddy current magnetic separation roller 10 is a device for material sorting. Its working principle is to use the interaction between magnetic force and electric force to separate metal and non-metal materials in the material. The eddy current magnetic separation roller 10 is mainly composed of a roller, an excitation coil and a control system. The surface of the roller is covered with a layer of conductive material. When the excitation coil is energized, an eddy current will be generated on the surface of the roller. When materials with different conductive properties pass through the surface of the roller, the metal material with good conductive properties will be induced by the eddy current to generate a magnetic field, thereby being attracted to one side of the roller, while the non-metal material will not be affected, thus achieving the separation of metal and non-metal.

[0027] Working principle: When the staff needs to screen the decoration engineering waste, the staff first pours the waste into the crushing equipment on one side of the base 1. The large volume of waste falls on the surface of the conveyor belt 2 after being crushed. The staff opens the conveyor belt 2 so that the conveyor belt 2 transports the waste to the right. At the same time, the staff turns on the first motor 7 and the second motor 52 to rotate the rotating rod 6, and the electromagnet 4 above the rotating rod 6 falls down, so that the electromagnet 4 is as close to the stirring plate 8 below as possible. When the waste passes through the stirring plate 8, a large amount of waste on the surface of the conveyor belt 2 is turned up by the stirring plate 8, and the electromagnet 4 above can suck out the metal iron contained in the waste, and then the conveyor belt 2 continues to transport the waste to the right. The staff opens the eddy current magnetic separation roller 10 below. When the waste moves above the eddy current magnetic separation roller 10, the non-ferrous metals in the waste will be ejected and fall into the second recycling box 12, while other waste will fall into the first recycling box 11, so as to complete the screening operation of the decoration engineering waste.
