Description

Technical Field

[0001] This utility model belongs to the technical field of material separation devices, and particularly relates to metal separation devices. Background Technology

[0002] Metal separation devices are used to remove metal particles from granular materials. In existing technology, a falling metal detector is commonly used for metal particle separation. When the material to be tested passes through the metal detector head located inside the device, it is determined whether the material contains metal particles. The bottom of the device has a channel structure for switching directions (one direction for receiving good products, and the other for receiving defective products). The outlet of the metal detector head is directly connected to the inlet of the aforementioned channel structure. This structure has the following drawbacks: the switching direction is generally achieved through mechanical action, and defective products can easily enter the channel for receiving good products during the aforementioned mechanical action, thus affecting the accuracy of separation.

[0034] In one embodiment of this utility model, such as Figures 1-3As shown, a metal separation device is provided, including a drive assembly 50, a material placement chamber 12 arranged from top to bottom, a metal detection assembly 20, a communication assembly 30, and a material distribution chamber 41. The metal detection assembly 20 has a vertically arranged first channel 21, and the communication assembly 30 has a vertically arranged second channel 31 whose top end is connected to the first channel 21. The bottom of the material distribution chamber 41 has a vertically arranged material drop channel 421 extending outward, and the side has an inclined waste channel 431 extending outward. A flipping plate 44 is movably connected inside the material distribution chamber 41. The output end of the drive assembly 50 is connected to the flipping plate 44, enabling the material drop channel 421 or the waste channel 431 to communicate with the second channel 31. The metal detection assembly 20 is electrically connected to the drive assembly 50. Specifically, the metal detection component 20 is a metal detector head with a shell. The first channel 21 runs vertically through the metal detector head. The inner cavity of the metal detector head is equipped with a detection coil that is arranged around the outside of the first channel 21. When the metal detector head detects metal particles mixed in the falling material, it transmits an electrical signal to the processor 51. The processor 51 controls the solenoid valve 53 to perform an action according to the aforementioned electrical limit signal. The piston rod of the cylinder 52 is pulled back, causing the flip plate 44 to flip downward, so that the second channel 31 is connected to the waste channel 431. The defective material slides down the tilting direction to the outside of the dispensing chamber 41, thereby completing the removal of metal particles. When the metal detector head does not detect metal particles in the falling material, it transmits an electrical signal to the processor 51. The processor 51 controls the solenoid valve 53 to perform an action according to the aforementioned electrical limit signal. The piston rod of the cylinder 52 is pushed out, causing the flip plate 44 to flip upward, so that the second channel 31 is connected to the dropping channel 421.

[0035] In one embodiment of this utility model, such as Figures 1-2 As shown, the drive assembly 50 includes a processor 51, a cylinder 52, and a solenoid valve 53. The processor 51 and the solenoid valve 53 are electrically connected to the processor 51. The cylinder 52 is connected to an external air source through the solenoid valve 53. The end of the flipping plate 44 is provided with a rotating shaft 441, which is rotatably connected to the side wall of the material distribution chamber 41. The free end of the piston rod of the cylinder 52 is hinged to a swing arm 521, and the other end of the swing arm 521 is fixedly connected to the end of the rotating shaft 441. When the piston rod of the cylinder 52 is pushed out, the rotating shaft 441 drives the flipping plate 44 to flip upward, thereby connecting the material discharge channel 421 with the second through hole. When the piston rod of the cylinder 52 is pulled back, the rotating shaft 441 drives the flipping plate 44 to flip upward, thereby connecting the waste channel 431 with the second channel 31. The structure is simple and easy to assemble.

[0036] In one embodiment of this utility model, such as Figures 1-3As shown, the rotating shaft 441 includes a shaft body, with connecting rods arranged coaxially at both ends of the shaft body. The inner end of the connecting rod is fixedly connected to the shaft body, and the outer end is provided with a D-shaped step.

Specifically, the D-shaped step includes a first straight section, a first arc section, a second straight section, and a second arc section connected at the first and second ends. The outline of the notch corresponds to the D-shaped step. The two straight sections are used to avoid relative rotation between the connecting rod and the swing arm 521 during transmission, thereby reducing the possibility of gaps between the free end of the flipping plate 44 and the cavity wall of the dispensing cavity 41 due to incomplete flipping. In this embodiment, the inner end of the connecting rod is provided with a D-shaped step with the same structure as the outer end, and the end of the shaft body is provided with a groove adapted to the D-shaped step. The connecting rod is coaxially provided with screw holes from the outside to the inside. After the D-shaped step and the groove are engaged, the end of the shaft body is fixed to the connecting rod by screws.

Specifically, the flipping plate 44 is a rectangular plate structure, and its connecting end is fixedly connected to the right-angled step of the shaft body by welding. The free end of the piston rod of the cylinder 52 is provided with a hinge seat 522, and the hinge seat 522 is movably connected to the swing arm 521.

The metal detection component 20, the connecting component 30, and the dispensing chamber 41 are respectively disposed in the inner cavity of the hollow outer shell 10. The material placement chamber 12 is opened on the funnel 11. The funnel 11 is located on the outer top of the hollow outer shell 10, and its outlet is connected to the first channel 21. Specifically, several material particles to be detected are placed in the material placement chamber 12 of the funnel 11. When the filling is complete, the material placement space is connected to the first channel 21 by pushing the push-pull plate 14. The aforementioned material particles to be detected fall one by one through the first channel 21 of the metal detector.

[0039] In one embodiment of this utility model, such as Figure 3As shown, it also includes a first assembly plate 13 and a push-pull plate 14. The first assembly plate 13 has a first through hole 131 corresponding to the first channel 21. The bottom of the first assembly plate 13 is fixedly connected to the outer top of the hollow shell 10, and the top is aligned with and fixedly connected to the discharge port of the funnel 11. The top of the first assembly plate 13 has a sliding groove 132. The push-pull plate 14 has a second through hole 141 and slides with the sliding groove 132. When the push-pull plate 14 slides, it can connect the material placement cavity 12 with the first channel 21 or isolate the material placement cavity 12 from the second channel 31. Specifically, the first assembly plate 13 is made of aluminum, which helps to improve the support strength. Both ends of the push-pull plate 14 are provided with upward-extending paddles for easy operation by technicians.
