Description

Technical Field

[0001] This utility model relates to a remote inoculant feeding device, belonging to the field of casting technology. Background Technology

[0002] In-flow inoculation refers to the process of uniformly adding an inoculant to the molten iron while pouring the metal during casting to achieve the purpose of inoculation. It is used to promote graphitization, refine grains, improve graphite morphology, reduce the tendency of white iron, and improve mechanical properties.

[0003] Traditional inoculants are mostly added manually with an iron spoon. Manual addition suffers from high labor intensity, low safety, and uneven inoculant addition speed control. To address this issue, CN201520966608.X discloses an in-flow inoculant adding device, including a mounting frame with an inoculant hopper fixed on it, and a valve body fixed at the outlet of the inoculant hopper. Automatic addition of the inoculant is achieved by manually controlling the valve stem. However, during manual valve stem control, the operator remains close to the molten metal, resulting in high working temperature and unfavorable environmental conditions, necessitating improvements in the safety of the feeding process.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

Detailed Implementation

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0020] Example 1 like Figures 1-2 As shown in the figure, this utility model provides a remote inoculant feeding device, including a hopper 1, which is used for storing inoculant. The bottom of the hopper 1 is provided with a discharge port 2, and a baffle plate 3 is hinged to the bottom of the discharge port 2. The baffle plate 3 can swing along the hinge, thereby realizing the opening or closing of the discharge port 2.

[0021] The baffle plate 3 is connected to the counterweight block 5 via the connecting rod 4, and the baffle plate 3 and the counterweight block 5 are fixedly installed at both ends of the connecting rod 4.

[0022] The middle part of the connecting rod 4 is fixedly connected to one end of the traction rope 6. The traction rope 6 is wound around the pulley 7, which is located on the hopper or other equipment on site.

[0023] When molten iron is transferred from the spheroidizing ladle to the casting ladle, the traction rope 6 is pulled, the counterweight 5 is raised, the baffle plate 3 leaves the discharge port 2, and the inoculant in the hopper 1 flows out into the molten iron flow. It enters the casting ladle along with the molten iron flow and fully mixes and reacts with the molten iron. After the molten iron flow stops, the traction rope 6 is released, the counterweight 6 hangs down under the action of gravity, and the baffle plate 3 tilts up to block the discharge port 2, thus realizing remote control of the inoculant feeding.

[0024] Example 2 like Figures 3-5 As shown in the figure, this utility model provides a remote inoculant feeding device. The difference between Example 2 and Example 1 is that: In Example 2, a flow guiding mechanism 8 is provided directly below the discharge port 2. The flow guiding mechanism 8 guides the inoculant to a suitable feeding position. The end of the traction rope 6 away from the connecting rod 4 is connected to the traction locking mechanism 9. The traction locking mechanism 9 is used to control the opening and closing angle of the baffle plate 3.

[0025] The flow guiding mechanism 8 includes a flared mouth 81, and a spherical shell 82 that communicates with the inner cavity of the flared mouth 81 is fixedly connected to the bottom of the flared mouth 81. The inner cavity of the spherical shell 82 is arranged longitudinally through the flared mouth 82. The spherical shell 82 is installed in a ball seat 83. The ball seat 83 is fixedly connected to the top end of the flow guiding pipe 84. The flow guiding pipe 84 communicates with the inner cavity of the spherical shell 82.

[0026] The guide tube 84 and the ball seat 83 can rotate and swing along the ball shell 82 to adjust the discharge port of the guide tube 84, so that the inoculant is added to the appropriate position.

[0027] The traction locking mechanism 9 includes a fixed arm 92 arranged in the horizontal direction. One end of the fixed arm 92 is mounted on the frame 97 via a slider 94. The height of the fixed arm 92 can be adjusted. The end of the fixed arm 92 away from the slider 94 is hinged to a swing arm 91 of a T-shaped structure.

[0028] The bottom end of the swing arm 91 is connected to the end of the traction rope 6, and the swing arm 91 drives the traction rope 6 to move.

[0029] The side of the swing arm 91 is fixedly connected to the arc-shaped arm 93, and the arc-shaped arm 93 has a plurality of evenly distributed adjustment holes 95; the fixed arm 92 has a locking hole 96, and the locking hole 96 is adapted to the position of the adjustment hole 95.

[0030] A pin is inserted into the locking hole 96 and the corresponding adjusting hole 95. The swing angle of the swing arm 91 is adjusted by the pin, and then the opening and closing angle of the baffle plate 3 is controlled by the traction rope 6.
