Therefore, the above terms should not be understood as limiting the present invention.

[0021] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0022] like Figure 1-2 As shown, a preferred embodiment of the present invention provides a drawing powder recovery and separation device, comprising a cleaning mechanism, a filtering mechanism and a drying mechanism, wherein the cleaning mechanism comprises a cleaning cylinder 1, an upper stirring part 3 and a lower stirring part 2; The cleaning cylinder 1 is used to contain wire drawing powder, a cleaning liquid inlet 1-1 is provided at the top of the cleaning cylinder 1, a discharge port 1-2 is provided at the bottom of the cleaning cylinder 1, the upper stirring part 3 and the lower stirring part 2 are both located in the cleaning cylinder 1, and the upper stirring part 3 is arranged at the top of the cleaning cylinder 1, and the lower stirring part 2 is arranged at the bottom of the cleaning cylinder 1; The filtering mechanism comprises a rectangular filter cylinder 4 and a filter plate 5 arranged in the filter cylinder 4, and the discharge port at the bottom of the cleaning cylinder 1 is connected to the top of the filter cylinder 4 through a pipeline; The drying mechanism 6 is connected to the filtering mechanism to recover and dry the filtrate flowing out of the filtering mechanism.

[0023] In the above technical scheme, wire drawing powder and cleaning liquid are mixed in the cleaning cylinder 1. Under the cleaning of the cleaning liquid, the wire drawing powder will dissolve in the cleaning liquid, and metal chips such as aluminum chips will be separated from the wire drawing powder. The liquid will be discharged into the filter mechanism through a pipe. Under the filtering action of the filter mechanism, the liquid containing the wire drawing powder will be separated from the metal chips and fall to the bottom of the filter plate. The liquid is then processed, dried and recovered. The specific composition of the cleaning liquid can be selected according to the composition of the wire drawing powder. For example, if the wire drawing powder is soluble in water, water can be used as the cleaning liquid.

[0024] In the cleaning cylinder, the upper stirring part and the lower stirring part are arranged separately, and whether to start both stirring parts at the same time or only start the lower stirring part can be determined according to the amount of liquid to be stirred. If the amount is small, only the lower stirring part needs to be started, and there is no need to start the upper stirring part.

[0025] In another technical solution, the upper stirring part 3 and the lower stirring part 2 both include a vertically arranged stirring shaft 2-1 and a plurality of stirring paddles 2-2 connected to the stirring shaft 2-1. The stirring paddles 2-2 are distributed up and down. The stirring shaft rotates when driven by a motor. One end of the stirring paddle 2-2 is connected to the stirring shaft 2-1, and the other end is close to the inner wall of the cleaning cylinder.

[0026] In the lower stirring part, the lowest stirring paddle is L-shaped, with its horizontal section close to the bottom of the cleaning cylinder and the vertical section close to the bottom of the cleaning cylinder, and the outer side of the L-shaped stirring paddle is connected to a straight rubber strip 2-3, the straight rubber strip 2-3 is a triangular prism, and one of the surfaces of the right-angle rubber strip is close to the bottom or inner wall of the cleaning cylinder.

[0027] The lowest stirring paddle in the lower stirring section is set to be L-shaped and close to the bottom and inner wall of the cleaning cylinder. This is because the liquid contains metal debris such as aluminum chips, which are easy to sink to the bottom due to their large mass, and the side walls are also easy to stick. A right-angle rubber strip is provided. As the stirring paddle rotates and stirs, the right-angle rubber strip can scrape off the sticky material on the bottom of the cylinder side wall.

[0028] In another technical solution, the stirring shaft of the upper stirring part 3 and the stirring shaft of the lower stirring part 2 rotate in opposite directions, so that the stirring effect is better.

[0029] In another technical solution, the filter mechanism further includes a vertically arranged support rod 7, one end of which is fixed to the bottom of the filter cylinder 4, and the other end of which can be rotatably hinged to the bottom of the filter plate 5. The support rod 7 supports the filter plate to improve its stability. The support rod is plate-shaped, and one side of it can be rotatably hinged to the bottom of the filter plate 5.

[0030] In another technical solution, the filter plate 5 includes a filter main board 5-1 and two filter side boards 5-2 at both ends thereof. The interior of the filter main board 5-1 is hollow, and the inner side wall of the filter main board 5-1 is provided with a limiting groove along its length direction. The filter side boards 5-2 slide left and right along the limiting groove, and the two filter side boards 5-2 are connected by a plurality of springs 5-3.

[0031] When the spring is in the shortest compression state, the two filter side plates extend out of the two ends of the filter main plate and abut against the inner wall of the filter cylinder, and the filter plate is in a horizontal state; When the spring is in the longest compression state, the two filter side plates extend out of the two ends of the filter main plate and abut against the inner wall of the filter cylinder, and the filter plate is in an inclined state.

[0032] When the filter plate 5 is tilted, one end thereof reaches the highest point and the other end reaches the lowest point. A discharge port is provided on the filter cylinder 4 at a position corresponding to the lowest point, and an electric valve is provided at the discharge port.

[0033] When a lot of metal powder is filtered and accumulated on the filter plate, the filter plate 5 is adjusted to be tilted, so that the metal debris on its surface can be quickly discharged and collected through the discharge port. However, considering that when the filter plate is tilted, there must be gaps between its two ends and the side wall of the cylinder, and the metal debris will leak out, a structure is provided so that the length of the filter plate can be adjusted by itself. As the filter plate is further tilted, the spring will be further released and rebounded, thereby driving the two filter side plates to extend from the two ends of the filter main plate and then against the inner wall of the cylinder.

[0034] In another technical solution, a hydraulic support rod 8 is vertically arranged below the filter side plate, the fixed end of the hydraulic support rod is fixed to the bottom of the filter cylinder, the telescopic end of the hydraulic support rod is connected to the bottom of the outer end of the filter side plate, and the hydraulic support rod is connected to a PLC controller. After receiving external instructions, the PLC controller raises and lowers the hydraulic support rod according to the external instructions. During the tilting process of the filter plate, the hydraulic support rod will provide good support for the filter plate, and the hydraulic support rod can also actively lead the filter plate to achieve the tilting adjustment process.

[0035] In another technical solution, the outer end surface of the filter side plate is wrapped with an anti-collision layer, which can prevent the filter side plate from scratching the side wall of the cylinder during the tilting process and causing damage.

[0036] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
