Description

Technical Field

[0001] The utility model relates to the field of copper powder production, in particular to a separation device for copper powder production. Background Art

[0002] Copper powder is used in various industries and uses high-purity copper powder. However, it is inevitable that various substances such as plastic or rubber are mixed into the copper powder when it is produced. Therefore, a separation device for copper powder production is very necessary. However, the existing separation device generally uses a centrifuge for separation. This method is costly and inefficient, cannot meet the current use needs, and cannot be effectively separated in large quantities, which reduces the use effect. To solve the above problems, after searching, a separation device for copper powder production with the authorization publication (announcement) number CN214913668U was found. The article proposes that: a drive motor 21 provides the necessary power output for mixing and stirring the entire device, and drives the transmission rod 23 to rotate inside the movable bearing 22, thereby driving the stirring blade 24 to rotate to complete the mixing task;

[0003] However, when the above device is actually used, the stirring blades are set above the copper powder. When the stirring blades rotate, the copper powder cannot be fully stirred, so that the rubber impurities contained in the copper powder pile cannot float on the water surface above the copper powder, and the effect of separating impurities from the copper powder is poor.

[0005] To achieve the above-mentioned purpose, a separation device for copper powder production is provided, comprising a separation tank, a fixed plate fixedly installed on the top of the separation tank, and a reduction motor screwed and fixed on the surface of the fixed plate, while the output shaft of the reduction motor is fixedly connected to the stirring rod through a coupling, and a stirring and separation assembly is fixedly installed on the bottom of the stirring rod, a feeding port is installed on the surface of the fixed plate, a powder discharge pipe is fixedly provided at the bottom of the separation tank, and a suction pipe is fixedly provided in the middle of the separation tank, the stirring and separation assembly includes an outer stirring blade, and a middle stirring blade is provided on the inner side of the outer stirring blade, and an inner stirring blade is provided on the side of the middle stirring blade away from the outer stirring blade.

[0006] Preferably, a limiting tube is provided in the middle of the interior of the separation tank, and a limiting hole is provided inside the limiting tube, and the stirring rod is adapted to the size of the limiting hole, and the stirring rod is inserted into the limiting hole.

[0007] Preferably, the axial cross-section of the limiting tube and the stirring rod is a concentric circle structure, and four groups of reinforcement frames are evenly arranged on the circumferential outer wall of the limiting tube. At the same time, the reinforcement frame is fixedly arranged on the inner wall surface of the separation tank at one end away from the limiting tube, and the reinforcement frame is arranged in an isosceles trapezoid.

[0008] Preferably, the stirring and separating component is arranged in a daisy shape as a whole, and the stirring and separating component is driven to rotate by a stirring rod and a reduction motor at the bottom of the separation tank.

[0009] Preferably, the stirring and separating components are evenly arranged in eight groups along the outer circumferential wall of the bottom of the stirring rod, and the eight groups of stirring and separating components are centrally symmetrical structures about the stirring rod.

[0010] Preferably, the outer stirring blade, the middle stirring blade and the inner stirring blade are all made of stainless steel and are "C"-shaped structures, and are fixed by two sets of connecting columns. At the same time, the curvature of the outer stirring blade, the middle stirring blade and the inner stirring blade are consistent, and the curvature of the outer stirring blade is consistent with the curvature of the inner wall of the bottom of the separation tank.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The distance between the bottom of the stirring and separating component and the bottom surface of the separation tank is 1 cm. When the stirring and separating component rotates, it can evenly stir the copper powder that has settled on the bottom. The rubber impurities accumulated inside the copper powder pile come into contact with water and float on the water surface, making it easy to remove.

[0013] 2. The utility model can generate a complex fluid flow pattern during the stirring process by designing the stirring and separating components into a chrysanthemum shape; this enables the copper powder and the water to be fully stirred in different directions, thereby improving the uniformity of the mixing; and can more effectively evenly distribute the components. During the process of sufficient mixing and contact between the copper powder and the water, the rubber impurities in the copper powder can come into contact with the water and float on the water surface under the action of buoyancy. The end of the suction pipe is externally connected to a suction pump to extract and remove the rubber impurities floating on the water surface, thereby achieving sufficient separation of the copper powder and rubber impurities.
