Description

Technical Field

[0001] The utility model relates to the technical field of metal granulation, in particular to a metal granulation device. Background Art

[0002] In order to improve metal transportation efficiency, save metal storage space, or realize the chemical properties of metals, metals need to be made into particles.

[0003] Therefore, Chinese patent CN106077686B discloses a metal particle preparation device and preparation method, including a rotary granulation system, a cooling system, a metal particle collection structure and a cooling water collection structure; in the rotary granulation system, molten metal is injected into a turntable, and the turntable is driven by a driving motor to rotate to granulate the molten metal; the cooling system cools the metal particles splashed out by the granulation.

[0004] In the above device, metal granulation is achieved by rotating a turntable, which is not only costly and complex in structure, but also causes the metal particles to be subjected to inconsistent centrifugal forces from the turntable, resulting in relatively large differences in the shapes of the metal particles. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model discloses a metal granulation device.

[0006] The utility model provides a metal granulation device, comprising a liquid storage cylinder and a drip plate;

[0007] The drip plate is arranged horizontally and is provided with a plurality of drip holes arranged vertically and penetrating the upper and lower sides of the drip plate;

[0008] The outer ring of the drip plate is provided with a baffle ring protruding upward;

[0009] The liquid storage cylinder is used to store liquid metal. A liquid outlet is arranged at the lower end of the liquid storage cylinder, and the outlet of the liquid outlet is directly opposite to the center position of the drip plate.

[0010] First, place the liquid metal in the liquid storage cylinder, and the liquid metal will enter the drip plate along the liquid outlet hole; the liquid metal at the drip hole will fall into the water in the form of water drops along the drip hole, and cool into particles; and when the liquid metal falls to the water surface, it will be blocked by the surface tension of the water, thus forming a disc shape, which ensures that it is easy to transport and store. When used by subsequent customers, the metal particles have a large surface area and a thinner thickness, so they are easier to melt, easier to react, and have better performance. Compared with the traditional structure, the utility model has a simple structure, low cost, and the shape of the metal particles is consistent, and the quality is higher.

[0011] If the distances at which liquid metals fall into the water surface are inconsistent, there will be a difference in the solidification temperature of the liquid metal that is close and the liquid metal that is far away, resulting in a large difference in the shape of the metal particles. Based on this, further improvements are: the drip plate is provided with multiple layers of drip holes from the inside to the outside; each layer is provided with multiple rotationally symmetrical drip holes; the circles formed by the drip holes of each layer are concentric, and the spacing between the formed circles is equal.

[0012] When the liquid metal falls onto the drip plate, its flow direction is difficult to control, so the liquid metal on the drip plate is unevenly distributed, which affects the metal granulation efficiency. Based on this, further improvements are: the upper end of the drip plate is provided with concentrically arranged convex rings; the drip holes are provided between the convex rings and the retaining rings. In this way, the liquid metal will first accumulate between the convex rings, and when the convex rings are full and overflow, they will flow evenly to the surroundings, so that the liquid metal is evenly distributed between the convex rings and the retaining rings; the outlet of the liquid outlet is directly opposite to the center of the convex ring.

[0013] In order to improve the stability of the liquid metal flowing out of the convex ring, a further improvement is that the cross section of the convex ring is an upwardly convex inferior arc shape. In this way, the liquid metal passing over the top of the convex ring will flow out immediately and will not be retained on the top of the convex ring.

[0014] In order to further improve the uniformity of liquid metal distribution, specifically: multiple spacer rings with the same spacing, concentric arrangement, and upward protrusion are arranged between the convex ring and the retaining ring; the height of the spacer ring is lower than the height of the convex ring; the spacer rings and the spacer rings and the convex rings are transitioned through concave arc surfaces; the drip holes are set at the bottom of the arc surface. In this way, multiple spaced liquid storage tanks will be directly formed between the spacer rings and between the spacer rings and the convex rings. When the liquid metal flows out of the outer side of the convex ring, it will fill the liquid storage tanks one by one, so that the liquid metal in each liquid storage tank is more evenly distributed.

[0015] In order to ensure that the liquid metal can drip out of the dripping hole stably and evenly, a further design is that the dripping hole has a wedge-shaped cross section with the expanded end facing upward.

[0016] If the height of the convex ring is higher than the retaining ring, when the liquid metal overflows from the convex ring, an impact force will be formed, which is easy to overflow from the inside of the retaining ring to the outside, causing a safety accident. Based on this, a further improvement is that the height of the convex ring is lower than the retaining ring.

[0017] To facilitate the installation of the drip plate, a further design is: a bracket is installed at the lower end of the liquid storage cylinder; the brackets are arranged in two symmetrical positions, both are L-shaped, and are composed of a vertical plate arranged vertically and a horizontal plate arranged horizontally; the horizontal plates are opposite; an outer flange is also provided on the top of the retaining ring; the lower end surface of the outer flange abuts against the upper end surface of the horizontal plate.

[0018] When the liquid metal falls onto the drip plate, the temperature will drop, thus affecting the stability of the liquid metal falling. Based on this, a further improvement is that a heating wire is also installed on the outer wall of the vertical plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0025] like Figure 1 As shown, the utility model discloses a metal granulation device, comprising a liquid storage cylinder 1 and a circular drop plate 2. A bracket is installed at the lower end of the liquid storage cylinder 1, and a bracket 8 is installed on the bracket. The bracket 8 is provided with two symmetrically arranged brackets 8, both of which are L-shaped, and are composed of a vertically arranged vertical plate 81 and a horizontally arranged horizontal plate 82; the horizontal plates 82 are opposite.

[0026] The lower end of the liquid storage cylinder 1 is provided with a liquid outlet hole 11, and the liquid metal flows downward from the liquid outlet hole 11. The drip plate 2 is arranged horizontally and is arranged directly below the liquid outlet hole 11. The drip plate 2 is provided with a plurality of drip holes 3 arranged vertically and penetrating the upper and lower sides of the drip plate 2. The liquid metal drips downward from the drip holes 3 into the water in the shape of water drops and is cooled into particles.

[0027] The drip hole 3 has a wedge-shaped cross section with the expanded end facing upwards, so as to increase the amount of liquid metal at the inlet of the drip hole 3, and when liquid metal drips out of the outlet of the drip hole 3, the missing amount can be replenished immediately, so that the liquid metal can drip stably and continuously.

[0028] like Figure 3As shown, the drip holes 3 are arranged in multiple layers, and each layer is provided with multiple rotationally symmetrical drip holes 3; the circles formed by the drip holes 3 in each layer are concentric, and the spacing between the formed circles is equal. And the corresponding drip holes 3 in each layer are arranged linearly, and the straight line formed by them coincides with the center of the circle of the drip plate 2. In this way, the distance when the liquid metal falls into the water surface is consistent, so that the shape of the metal particles remains consistent when they are formed.

[0029] like Figure 2 As shown, the outer ring of the drip plate 2 is provided with an upwardly protruding baffle ring 4, so that a liquid storage cavity is formed on the upper side of the drip plate 2. The top of the baffle ring 4 is also provided with an integrally formed outer flange 41, which is arranged horizontally, and its lower end face abuts against the upper end face of the horizontal plate 82, so that the drip plate 2 can be installed below the liquid storage cylinder 1, which is convenient for the stable progress of the metal granulation process. The outer wall of the vertical plate 81 is also installed with an electric heating wire 9, which can heat the liquid metal, so that the temperature of the liquid metal flowing into the drip plate 2 remains stable, and the liquid metal is prevented from affecting the stability of dripping due to the temperature drop.

[0030] The upper end of the drip plate 2 is provided with a concentrically arranged convex ring 5; the drip hole 3 is provided between the convex ring 5 and the retaining ring 4, and the outlet of the liquid outlet hole 11 is directly opposite to the center position inside the convex ring 5. With such a configuration, the liquid metal will first accumulate between the convex rings 5, and when the convex rings 5 ​​are full and overflowing, they will flow evenly to the surroundings, so that the liquid metal is evenly distributed between the convex ring 5 and the retaining ring 4. The cross section of the convex ring 5 is an inferior arc shape that bulges upward. With such a configuration, when the liquid metal passes over the top of the convex ring 5, it will immediately flow outwards and will not stay on the top of the convex ring 5, thereby improving the stability of the liquid metal flowing out from the convex ring 5.

[0031] The height of the convex ring 5 is lower than the baffle ring 4. With such an arrangement, when the liquid metal overflows from the convex ring 5, an impact force will be formed. This impact force will act on the baffle ring 4. Since the baffle ring 4 is higher than the convex ring 5, the baffle ring 4 will be higher than the liquid level of the liquid metal, so that the baffle ring 4 can block the liquid metal in the liquid storage chamber and will not overflow to cause a safety accident.

[0032] A plurality of spacer rings 6 with the same spacing, concentric arrangement and upward protrusion are also arranged between the convex ring 5 and the retaining ring 4; the height of the spacer rings 6 is lower than that of the convex ring 5; the spacer rings 6 and the spacer rings 6 and the convex ring 5 are transitioned through concave arc surfaces 7; and the drip holes 3 are arranged at the bottom of the arc surfaces 7. In this arrangement, a plurality of spaced liquid storage tanks are directly formed between the spacer rings 6 and between the spacer rings 6 and the convex ring 5. When the liquid metal flows out of the outer side of the convex ring 5, it will fill the liquid storage tanks one by one, so that the liquid metal in each liquid storage tank is more evenly distributed.

[0033] First, place the liquid metal in the liquid storage cylinder 1, and the liquid metal will enter the drip plate 2 along the liquid outlet hole 11; the liquid metal at the drip hole 3 will fall into the water along the drip hole 3 in the shape of water drops, and cool into particles; and when the liquid metal falls to the water surface, it will be blocked by the surface tension of the water, thus forming a disc shape, which ensures that it is easy to transport and store. When used by subsequent customers, the metal particles have a large surface area and a thinner thickness, so they are easier to melt, easier to react, and have better performance. Compared with the traditional structure, the utility model has a simple structure, low cost, and the shape of the metal particles is consistent, and the quality is higher.

[0034] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
