Description

Technical Field

[0001] This application relates to the field of metal processing waste recycling and treatment technology, and in particular to a separation device for metal processing waste recycling and treatment. Background Technology

[0002] Metal processing generates a large amount of scrap and chips, which are classified as waste metals. For example, the chips generated during titanium alloy processing contain a certain amount of metals such as iron, nickel, and copper, and have high resource utilization value. When metals are machined, the chips produced account for approximately 20% of the weight of the casting, and sometimes even as much as 30%.

[0003] Currently, the main methods for recycling and treating titanium alloy scrap include smelting, electrochemical reduction, chemical reduction, physical methods, and solidification. Among these, smelting consumes a large amount of power, and chemical methods inevitably produce pollution. Therefore, physical methods are widely used in the recycling and treatment of titanium alloy scrap.

[0004] Physical methods mainly include sieving, centrifugation, and gravity separation.

[0005] As per the instruction manual Figure 3-5 The diagram shows the first step in the physical treatment of metal scrap. The large amount of scrap collected during processing is first separated into smaller clumps and then placed in a crusher for further crushing. This breaks down the tangled metal scrap into loose, untangled particles, which are then subjected to further crushing, screening, and embrittlement processes. Figure 3 As shown, after recycling companies transport large amounts of waste from multiple processing plants back to the site by vehicle, the waste is usually tangled and needs to be separated into small clumps for crushing. Currently, manual separation operations are as follows: Figure 3-5 As shown, a tool with separating teeth is used to separate small clumps of waste.

[0006] The waste chips are continuously entangled during processing, so during separation, unseparated waste chips will become entangled with the waste chips being separated, such as... Figure 5 As shown, the entangled waste debris is difficult to separate quickly and thoroughly, usually requiring manual separation. However, the debris is quite sharp and can cause injury. In addition, large accumulations of waste debris will prolong the processing cycle and increase processing costs. Summary of the Invention

[0007] To address the aforementioned problems, this application aims to provide a separation device for recycling and processing metal processing waste, which enables the entangled waste to detach smoothly from the waste to be separated, thereby allowing the waste to be separated from the waste pile quickly and effectively improving the efficiency of waste separation operations.

[0008] To achieve the above objectives, the technical solution adopted in this application is as follows: a separation device for recycling and processing metal processing waste includes a drive handle, and a separation device with not less than two separation teeth is vertically sleeved at one end of the drive handle. The device is characterized in that a separation drive mechanism is provided on the waste separation side of the separation device to drive the waste to be separated from the unseparated waste, and the separation drive mechanism moves axially relative to the drive handle.

[0009] Preferably, the disengagement drive mechanism includes a suspension ring arranged axially at intervals on the drive handle, a drive rod passing through the suspension ring, and at least two disengagement teeth arranged on the drive rod outside the disengagement teeth.

[0010] Preferably, each of the disengagement teeth is circumferentially rotatably mounted on the drive rod.

[0011] Preferably, a contraction ring is fitted on the drive handle outside the separator, an arc-shaped contraction surface that abuts against the release tooth is provided on the side surface of the contraction ring located on the release tooth side, and a torsion spring is provided between adjacent release teeth.

[0012] The beneficial effects of this application are: by disengaging the drive mechanism during the waste separation operation, the entangled waste debris wrapped around the waste debris to be separated can be driven in the opposite direction, so that the entangled waste debris is detached from the waste debris to be separated, thereby enabling the waste debris to be separated from the waste debris pile to be separated quickly, thus effectively improving the efficiency of waste debris separation operation.

[0028] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] See attached document Figures 1-14 The separating device for recycling and processing metal processing waste includes a drive handle 1, and a separating device 2 with no less than two separating teeth 21 is vertically sleeved at one end of the drive handle 1, as shown in the figure. Figure 1-2 As shown, it typically has two separating teeth 21. During operation, the separating teeth 21 are engaged in the waste by driving the handle 1, and then the drive handle 1 is moved backward, so that part of the waste can be separated from the waste pile by using the separating teeth 21.

[0030] To address the current problem of entanglement between the waste to be separated and the unseparated waste during waste separation, such as... Figure 7-8As shown, a disengagement drive mechanism is provided on the waste separation side of the separator 2 to drive the waste to be separated from the unseparated waste. This disengagement drive mechanism moves axially relative to the drive handle 1. During operation, the separation teeth 21 and the disengagement drive mechanism are first simultaneously engaged in the waste pile by the drive handle 1. During the separation process, the disengagement drive mechanism is driven in the reverse direction by moving the drive handle 1 backward, driving the entangled waste on the waste to be separated in the reverse direction, which can cause the entangled waste to be separated from the waste to be separated, thereby enabling the waste to be separated from the waste pile quickly, thus effectively improving the efficiency of waste separation operation.

[0031] Specifically, such as Figure 6-8 As shown, the disengagement drive mechanism includes suspension rings 3 spaced axially along the drive handle 1, with a drive rod 4 passing through the suspension ring 3. At least two disengagement teeth 41 are provided on the drive rod 4 outside the disengagement teeth 21. During operation, as... Figure 7-8 As shown, firstly, the axial movement of the drive rod 4 causes the disengagement tooth 41 to approach the separation tooth 21. The drive handle 1 then simultaneously inserts both the separation tooth 21 and the disengagement tooth 41 into the waste pile. During the separation process, as the drive handle 1 moves backward, the drive rod 4 drives the disengagement tooth 41 in the opposite direction. The disengagement tooth 41 reverses the movement of the entangled waste debris on the waste pile to be separated, allowing the entangled waste debris to detach from the waste pile, thus enabling rapid separation of the waste pile from the waste pile. Before the next separation operation, the drive rod 4 again moves the disengagement tooth 41 closer to the separation tooth 21 and simultaneously inserts it into the waste pile.

[0032] Since the detachment area of ​​the detachment tooth 41 is limited, while the entanglement range of the waste chips is usually large, in order to increase the detachment area of ​​the detachment tooth 41, such as Figure 11 As shown, each of the release teeth 41 is circumferentially rotatably mounted on the drive rod 4. During the process of inserting the release teeth 41 into the waste and separating the waste, rotating each release tooth 41 increases the circumferential release area formed by the release teeth 41. Figure 11 As shown in the attached diagram on the right, this allows for the effective separation of tangled waste.

[0033] To further improve ease of operation, such as Figure 9-10As shown in Figures 12-14, a shrink ring 5 is fitted onto the drive handle 1 on the outside of the separator 2. An arc-shaped shrinking surface 5a is provided on the side surface of the shrink ring 5 located on the side of the release tooth 41, which abuts against the release tooth 41. A torsion spring (not shown in the figure) is provided between adjacent release teeth 41. Before operation, the release teeth 41 are moved toward the shrink ring 5 by the axial drive of the drive rod 4. After the release teeth 41 abut against the arc-shaped shrinking surface 5a on the shrink ring 5, they slide toward each other along the surface of the arc-shaped shrinking surface 5a, so that adjacent release teeth 41 (preferably two release teeth 41 in this application) overcome the force of the torsion spring and shrink together. After shrinking, they have a smaller width and can be inserted into the waste along with the separator 21. During the process of moving the drive handle 1 backward, the drive rod 4 is pushed in the opposite direction, causing the release tooth 41 to disengage from the arc-shaped contraction surface 5a of the contraction ring 5. Then, under the driving action of the torsion spring, the adjacent release teeth 41 rotate away from each other, thereby increasing the release area of ​​the entangled waste chips. The entangled waste chips can be completely separated, thereby improving the convenience of the waste chip separation operation and further improving the operation efficiency.

[0034] The principle of this application is as follows: Before the separation of waste chips, the axial drive of the drive rod 4 causes the release tooth 41 to move toward the shrink ring 5. After the release tooth 41 abuts against the arc-shaped shrink surface 5a on the shrink ring 5, it slides toward each other along the surface of the arc-shaped shrink surface 5a, so that the adjacent release teeth 41 overcome the force of the torsion spring and move closer to shrink. After shrinking, it has a smaller width and can be inserted into the waste chips together with the release tooth 21.

[0035] During the process of moving the drive handle 1 backward, the drive rod 4 is pushed in the opposite direction, causing the release tooth 41 to disengage from the arc-shaped contraction surface 5a of the contraction ring 5. Then, under the driving action of the torsion spring, the adjacent release teeth 41 rotate away from each other, thereby increasing the release area of ​​the entangled waste chips. The entangled waste chips can be completely separated, thereby improving the convenience of the waste chip separation operation and further improving the operation efficiency.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
