[0029] Example

[0030] like Figure 1-2As shown, the utility model provides a device for uniformly feeding refining agents in precision casting, including: a storage bin 1, a bracket 2, a rotating motor 3, and a discharge trough 4. A feed port 100 is arranged at the top of the storage bin 1, a first filter screen plate 110 is arranged at the bottom of the storage bin 1, the bracket 2 is arranged at the top edge of the storage bin 1, the rotating motor 3 is arranged at the top center of the storage bin 1, the output shaft 300 of the rotating motor 3 passes through from the top of the storage bin 1 to the bottom of the storage bin 1 and extends outward, the discharge trough 4 is arranged below the first filter screen plate 110, the end of the output shaft 300 is connected to the center of the discharge trough 4, a second filter screen plate 400 is arranged at the bottom of the discharge trough 4, and a third filter screen plate 410 is arranged on the side wall of the discharge trough 4. The device is arranged on the feeding port of the smelting metal, and the device is suspended in the feeding port through the bracket 2. The rotating motor 3 is started to rotate so that the discharging trough 4 rotates. Since the refining agent is stored in the storage bin 1 from the feeding port 100, the refining agent enters the discharging trough 4 from the first filter screen plate 110. The discharging trough 4 rotates to evenly throw the refining agent from the second filter screen plate 400 and the third filter screen plate 410 to the surface of the smelting metal. The smelting metal can be better fused with the refining agent, thereby improving the use effect of the refining agent.

[0031] In this embodiment, the bracket 2 includes: a connecting plate 200, a buckle plate 210, and a spring 220. One end of the connecting plate 200 is fixed at the top edge of the storage bin 1, and the bottom surface of the buckle plate 210 extends downward. One end of the spring 220 is connected to the connecting plate 200, and the other end is connected to the buckle plate 210. When the device is set at the feeding port of the smelting furnace, the buckle plate 210 is stretched so that the buckle plate 210 is connected to the outer wall of the feeding port. The spring 220 is in a stretched state so that the device can be more tightly connected to the feeding port.

[0032] In this embodiment, the number of meshes of the first filter plate 110 is smaller than that of the second filter plate 400, and the number of meshes of the first filter plate 110 is smaller than that of the third filter plate 410. The holes of the first filter plate 110 are larger, so that the refining agent can fall into the discharge trough 4 better. At the same time, the number of meshes of the second filter plate 400 and the third filter plate 410 is smaller than that of the first filter plate 110, so that the refining agent can be released more evenly. It should be noted that vibration will be generated during the rotation of the rotating motor 3, and the vibration will be transmitted to the storage bin 1, so that the refining agent can enter the discharge trough 4 from the first filter plate 110 more conveniently.

[0033] Preferably, the side wall of the storage bin 1 is made of transparent material, so that the operator can more quickly observe the delivery of the refining agent in the storage bin 1. In order to further accurately measure the amount of the refining agent, a scale is preferably set on the outer wall of the storage bin 1.

[0034] In this embodiment, if Figure 1-2As shown, the inner diameter of the discharge trough 4 is larger than the outer diameter of the storage bin 1, the upper edge height of the discharge trough 4 is higher than the bottom height of the storage bin 1, and the discharge trough 4 can surround the bottom of the storage bin 1, so that the refining agent in the storage bin 1 can enter the discharge trough 4 more fully. The storage bin 1 is a cylindrical structure, and the discharge trough 4 is a circular trough structure. The circular trough-shaped discharge trough 4 rotates more smoothly and has less wind resistance.

[0035] In this embodiment, two sets of sealed bearings 5 ​​are also included, one sealed bearing 5 is arranged at the top connection between the output shaft 300 of the rotating motor 3 and the storage bin 1, and the other sealed bearing 5 is arranged at the bottom connection between the output shaft 300 of the rotating motor 3 and the storage bin 1 (not shown). The arrangement of the sealed bearings 5 ​​facilitates the rotating motor 3 to drive the discharging chute 4 to rotate.

[0036] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
