Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a spheroidizing agent adding device for casting ductile iron castings. Background Art

[0002] Spheroidizing is a process for treating alloy liquid during cast iron casting to obtain spheroidized graphite, thereby improving the mechanical properties of cast iron. There are many spheroidizing processes, such as flushing method, bell method, wire feeding method, etc. When molten iron is spheroidized by flushing method, a barrel-shaped container called a spheroidizing bag is used to increase the contact time between molten iron and spheroidizing agent, improve the absorption rate of spheroidizing agent and stabilize the spheroidizing effect. Ferrosilicon is used as spheroidizing agent and needs to be added to the spheroidizing bag through a feeding device.

[0003] When the existing spheroidizer adding device is used, the spheroidizer is usually placed inside the silo, and then the spheroidizer is discharged from the silo to fall into the weighing device for weighing. The discharge speed of the spheroidizer inside the silo is not fixed. When the discharge speed is too fast, it is easy to cause too much spheroidizer inside the weighing device, and the excess spheroidizer needs to be manually removed. The accuracy of automatic batching is poor, and the spheroidizer is in an irregular solid form and is easily accumulated at the lower end of the silo, causing spheroidizer blockage. Utility Model Content

[0004] The utility model aims to provide a spheroidizing agent adding device for casting ductile iron castings, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A spheroidizing agent adding device for casting ductile iron castings comprises a silo and a support foot fixedly mounted on the lower surface of the silo, a support ring fixedly mounted on the inner surface of the silo, a base fixedly mounted on the inner surface of the support ring, a material guide assembly fixedly mounted above the base, the material guide assembly comprises a No. 1 motor fixedly mounted on the upper surface of the base, a No. 1 conical cover fixedly mounted on the output end of the No. 1 motor, a No. 2 conical cover rotatably connected to the outer side of the No. 1 conical cover, a weighing assembly fixedly mounted on the lower surface of the silo, the weighing assembly comprises a fixing frame fixedly mounted on the lower surface of the silo, a rotating shaft is rotatably connected between the fixing frames, a weighing device is fixedly mounted on the outer surface of the rotating shaft, and a spiral feeding mechanism is fixedly mounted on the outer surface of the silo.

[0007] Furthermore, a protective cover is fixedly installed on the outer side of the No. 1 motor and the inner surface of the No. 1 cone cover.

[0008] Furthermore, a rotating rod is fixedly mounted on the upper end surface of the No. 1 cone cover, a bearing is fixedly embedded in the upper end surface of the No. 2 cone cover, the rotating rod is fixedly passed through the inner ring of the bearing, and a top cap is fixedly mounted on the upper end surface of the rotating rod.

[0009] Furthermore, a plurality of No. 1 discharge troughs are equidistantly provided on the outer surface of the No. 1 conical cover, a plurality of No. 2 discharge troughs are equidistantly provided on the outer surface of the No. 2 conical cover, a plurality of stirring rods are equidistantly fixedly installed on the outer surface of the No. 2 conical cover, and a plurality of limit strips are equidistantly fixedly installed on the inner surface of the No. 2 conical cover on one side of the No. 2 discharge trough.

[0010] Furthermore, a collecting bin is fixedly mounted on the upper end of the outer surface of the spiral feeding mechanism through a bracket.

[0011] Furthermore, a No. 3 motor is fixedly mounted on one side surface of the fixed frame, the output end of the No. 3 motor is fixedly connected to the rotating shaft, a weighing bin is fixedly mounted on the upper surface of the weighing device, a No. 3 discharge trough is opened on the outer surface of the weighing bin, and a baffle is movably embedded inside the No. 3 discharge trough.

[0012] Preferably: the upper surface of the weighing bin is symmetrically fixed with connecting seats on both sides of the No. 3 discharge trough, the upper end of the baffle passes through the connecting seat and is rotatably connected to the connecting seat, the upper end surface of the weighing bin is fixedly installed with a No. 2 motor, and the output end of the No. 2 motor is fixedly connected to the upper end of the baffle.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The No. 1 motor is driven to rotate the No. 1 cone cover. At this time, the No. 2 cone cover is fixed under the pressure of the spheroidizer on the No. 2 cone cover. When the No. 1 discharge trough and the No. 2 discharge trough overlap, the spheroidizer falls from the overlapping part. The feeding speed is determined according to the overlapping area. Then the No. 1 motor drives the No. 1 cone cover to rotate in the opposite direction, so that the No. 1 cone cover blocks the No. 2 discharge trough and presses against the limit bar set on the inner side of the No. 2 cone cover, so that the No. 1 cone cover can drive the No. 2 cone cover to rotate synchronously, and the spheroidizer inside the silo is stirred by the stirring rod to prevent the spheroidizer from being blocked. Therefore, the material guide component is set inside the silo to control the feeding speed of the spheroidizer, and the spheroidizer inside the silo is stirred at the same time to prevent the spheroidizer from being blocked at the bottom of the silo, so that the spheroidizer can be discharged smoothly.

[0015] 2. When there is too much spheroidizer in the weighing bin, the No. 3 motor starts to operate, driving the weighing bin to flip in the opposite direction. Then the No. 2 motor starts to operate, driving the baffle to rotate and open the bottom of the No. 3 discharge chute. According to the opening area of ​​the No. 3 discharge chute and the flipping angle of the weighing bin, the discharge speed of the spheroidizer is controlled, so that the excess spheroidizer is poured into the collection bin and fed into the silo through the spiral feeding mechanism. Therefore, when the discharge speed is too fast and there is too much spheroidizer in the weighing device, the excess spheroidizer is automatically removed to improve the accuracy of automatic batching.

[0027] In this embodiment, for the sake of clarity, the No. 1 motor 201 is running, driving the No. 1 cone cover 202 to rotate. At this time, the No. 2 cone cover 206 is fixed under the pressure of the spheroidizing agent on the No. 1 cone cover 206. When the No. 1 discharge trough 205 and the No. 2 discharge trough 207 overlap, the spheroidizing agent falls from the overlapping part, and the discharge speed is determined according to the overlapping area.
