Description

Technical Field

[0001] The utility model relates to the field of casting impurity removal devices, in particular to a separation and impurity removal device for manufacturing high-wear-resistant castings. Background Art

[0002] In the casting manufacturing industry, scrap metals need to be recycled and reused. These recycled scrap metals have often been preliminarily sorted, but they may still be mixed with various impurities, such as wood chips, dust and plastics. These impurities need to be removed or separated before re-melting to ensure the quality and purity of the metal.

[0003] However, the current separation process mainly relies on manual labor, which includes multiple steps such as removing plastics, wood chips and dust one by one, making the entire separation process cumbersome and inefficient, resulting in high labor and time costs.

[0004] Therefore, in view of the above-mentioned situation that impurities need to be separated manually from scrap metal, which results in high labor and time costs, a separation and impurity removal device for the manufacture of highly wear-resistant castings can be designed. Through a threaded transmission structure and a filtering separation structure, impurities can be separated from the old metal while avoiding the trouble of manual separation. Utility Model Content

[0007] Preferably, the bottom plate is the base of the entire device, and the support legs at the lower end of the bottom plate serve to support and stabilize the entire device. The collection box is used to collect impurities separated from the separation box. When the collection box is full of impurities, it can be easily taken out of the separation box and emptied. The ultrasonic generator assists the separation process by generating ultrasonic waves. The vibration of the ultrasonic waves can separate the impurities in the scrap metal from the metal body, thereby improving the separation efficiency. The separation component can effectively separate impurities such as wood chips, dust and plastic from the scrap metal through the screening net. The lifting component is driven by a motor, thereby driving the stirring component to perform lifting and lowering movements. The stirring component flips and stirs the scrap metal pile to make it better contact with the ultrasonic waves generated by the ultrasonic generator, thereby improving the separation efficiency.

[0008] Preferably, the separation assembly includes a support plate, a cylinder, and an articulated seat; there are two support plates that are symmetrically fixed to the inner wall of the separation box, two groups of front-to-back symmetrical cylinders are installed on the upper end of the left support plate, and an articulated seat is installed on the upper end of the right support plate. The support plate is the basic part of the separation assembly and there are two of them. The cylinder serves as a power source. When the cylinder is actuated, the piston rod will push the screening plate to rotate, and through the articulated seat, the angle of the screening plate can be adjusted so that the screened metal can be taken out from the discharge port.

[0009] Preferably, the separation assembly also includes a screening plate, a screening net, and a discharge port; the right end of the screening plate is rotatably connected to the hinge seat, the lower surface of the left end of the screening plate is connected to the power output element of the cylinder, a screening net for separating impurities is installed in the screening plate, and the discharge port is opened at the right end of the separation box.

Impurities in scrap metal are separated through its mesh holes, while ensuring that the metal body can be isolated at the upper end of the screening net. The discharge port is used for allowing staff to take out the separated metal.

When the motor receives a control signal, its output shaft will drive the No. 1 threaded rod to rotate. The No. 1 rotating groove provides a support and rotation track for the No. 1 threaded rod and the No. 2 threaded rod, ensuring the stability of the No. 1 threaded rod and the No. 2 threaded rod during the rotation process. The No. 1 threaded rod and the No. 2 threaded rod interact with the lifting plate through threaded connection to realize the lifting movement of the lifting plate.

[0011] Preferably, the lifting assembly also includes a lifting plate, a driving wheel, a driven wheel, and a belt; there are two lifting plates and internal threads are provided inside thereof, which are compatible with the external threads of the No. 1 threaded rod and the No. 2 threaded rod.

The No. 2 servo motor serves as the power source of the stirring assembly. When the No. 2 servo motor receives a control signal, its output shaft will drive the No. 2 coupling and the rotating shaft to rotate. The stirring blades are used to generate stirring force when the rotating shaft rotates, so that it can better contact with the ultrasonic wave generated by the ultrasonic generator, thereby improving the separation efficiency.

At the same time, since the second threaded rod 905 is connected to the first threaded rod 904 through the belt 909, the driving wheel 907 and the driven wheel 908, the second threaded rod 905 will also rotate synchronously, thereby ensuring that the two lifting plates 906 can be lifted and lowered synchronously. The stirring assembly includes a fixed plate 1001 and a second rotating groove 1002; the fixed plate 1001 is fixedly connected to the upper end of the lifting plate 906 on the left side, and the second rotating groove 1002 is installed at the right end of the fixed plate 1001.

[0028] When performing metal separation, the staff first places the old metal to be processed on the screening net 805, and then starts the No. 1 servo motor 901, which drives the No. 1 threaded rod 904 to start rotating. Due to the effect of the thread, the lifting plate 906 will smoothly descend along the threaded rod. At the same time, since the No. 2 threaded rod 905 is connected to the No. 1 threaded rod 904 through the belt 909, the driving wheel 907 and the driven wheel 908, the No. 2 threaded rod 905 will also rotate synchronously, ensuring that the two lifting plates 906 can descend in a coordinated manner.

[0030] When the separation work is completed, pull the collecting box 4 to remove the impurities collected therein. Then, by controlling the lifting assembly, the stirring assembly will slowly rise. Finally, control the cylinder 802 to move, and the piston rod pushes the screening plate 804 to rotate through the hinge seat 803 to achieve the angle adjustment of the screening plate 804, so that the screened metal can be smoothly taken out from the discharge port 806.

[0031] Through the above steps, when the separation component, the lifting component and the stirring component work together, not only can the impurities be effectively separated from the scrap metal, but the scrap metal pile can also be cleverly turned and stirred to ensure that these metals are in full contact with the ultrasonic waves generated by the ultrasonic generator 5, thereby greatly improving the separation efficiency. The lifting component shows its flexibility and can adjust the height of the stirring component as needed, effectively avoiding potential interference with other components, and solving the problem of manually separating impurities from scrap metal, thereby causing high labor costs and time costs.
