Description

Technical Field

[0001] The present application relates to the technical field of casting, and in particular to a flow-inoculation feeding device. Background Art

[0002] Inoculation refers to the process of adding a small amount of inoculant to the liquid metal during the solidification process to promote nucleation, inhibit growth, and achieve the purpose of grain refinement. Generally, in-stream inoculation is not performed during cast iron production, but for products with high grades and strict material requirements, in-stream inoculation is required. In metallurgical operations, it is usually necessary to add inoculant to the liquid metal during pouring to promote graphitization, refine grains, and reduce the tendency of white cast iron. Inoculant is a kind of agent that can promote graphitization of cast iron, reduce the tendency of white cast iron, improve the morphology and distribution of graphite, increase the number of eutectic groups, and refine the matrix structure. It has a good effect in a short time after inoculation (about 5-8 minutes) and is mainly suitable for general castings or later instantaneous inoculation in various situations.

[0003] Chinese patent publication number 201610431108.5 discloses a hopper with a ladle and a hopper for storing inoculant, wherein a first support rod and a second support rod are fixed on both sides of the hopper on the same center line, the hopper is above the ladle, and a feeding port is provided at the top of the hopper, a plug is provided on the feeding port, and a discharge port is provided at the bottom of the hopper. Support plates are fixed on the outer wall of the ladle and on the parts on both sides of the ladle port, and the two support plates are respectively connected with a first fan-shaped groove plate and a second fan-shaped groove plate with relatively symmetrical positions, and the first fan-shaped groove plate and the second fan-shaped groove plate are each provided with a plurality of radial grooves, and the first support rod and the second support rod are respectively placed on the radial grooves corresponding to the first fan-shaped groove plate and the second fan-shaped groove plate, and the first support rod is provided with an insert plate matching the radial groove of the first fan-shaped groove plate, and the insert plate is inserted into the radial groove of the first fan-shaped groove plate.

[0004] In the related art, a plurality of radial grooves are respectively provided on the first sector trough plate and the second sector trough plate, thereby forming a plurality of gears at different angles. The hopper is mounted on the corresponding gears of the first sector trough plate and the second sector trough plate through the first support rod and the second support rod. The hopper rotates with the rotation of the ladle, and the pouring angle of the ladle will change during the pouring process. During the pouring process, the operator can conveniently adjust the gear position of the hopper and change the inclination angle of the hopper so that the discharge port of the hopper is always facing the molten iron flow.

[0005] Regarding the above-mentioned related technologies, the inventors believe that there are the following defects: when the ladle rotates at too large an angle, the hopper cannot be aligned with the ladle and the gear needs to be manually adjusted, which is not convenient to use. Secondly, after the hopper rotates at a large angle, the inoculant in the hopper will dump out, affecting the efficiency of the inoculant falling out, making the addition of the inoculant uneven. Utility Model Content

[0008] A flow-inoculation feeding device comprises a ladle and a pouring gate, support plates are fixed on both sides of the pouring gate, rotating rods are passed through the tops of the two support plates, the rotating rods are rotatably connected to the corresponding support plates, an inoculant storage hopper is fixedly connected to the inner sides of the two rotating rods, one of the rotating rods passes through the support plate and is fixedly connected to the first gear, the bottom of the first gear is meshed with a second gear, one side of the second gear passes through the support plate and is rotatably connected to the support plate, and the other end is connected to the output shaft of the rotating motor, and a tightening mechanism is provided on the top of the inoculant storage hopper;

[0010] By adopting the above technical solution, when the ladle rotates, the inoculant storage hopper is kept horizontally downward under the action of gravity, and the inoculant storage hopper can feed the inoculant into the ladle. When the rotation angle is too large and the inoculant storage hopper cannot feed the inoculant into the ladle, the controller is turned on to control the rotation of the rotary motor, thereby driving the second gear and the first gear to rotate, so that the inoculant storage hopper rotates and aligns with the ladle for easy use. The electric telescopic rod of the tightening mechanism extends when the inoculant storage hopper rotates, squeezing the sealing plate so that the sealing plate squeezes the inoculant inside the inoculant storage hopper to prevent the inoculant from dumping, so that the inoculant is always at the bottom of the inoculant storage hopper for easy discharge.

[0011] Preferably, a counterweight is provided around the outer side of the bottom of the inoculant storage hopper.

[0012] By adopting the above technical solution, when the ladle is rotating, the inoculant storage hopper is always kept vertically downward under the action of gravity.

[0013] Preferably, a discharge port is fixed at the bottom of the inoculant storage hopper, and the discharge port corresponds to the gate.

[0015] Preferably, the bracket is fixedly arranged on one side of the inoculant storage hopper, an extension edge is provided around the bottom of the sealing plate, and a pressure sensor fixedly connected to the sealing plate is provided inside the extension edge.

[0016] By adopting the above technical solution, the sealing plate can be extended to push the inoculant to the middle of the inoculant storage hopper when it is squeezed downward, so as to facilitate rapid and flat extrusion. The pressure sensor can sense the pressure at the bottom of the sealing plate and then control the extension and retraction of the electric telescopic rod.

[0017] Preferably, a controller is fixed to one side of the ladle, the controller is electrically connected to the pressure sensor, and the electric telescopic rod is electrically connected to the controller.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. Through the setting of the rotary motor, the second gear and the first gear, when the ladle rotates too much and the inoculant storage hopper cannot deliver the inoculant into the pouring gate, the controller is turned on to control the rotary motor to rotate, thereby driving the second gear and the first gear to rotate, so that the inoculant storage hopper rotates and aligns with the ladle, which is convenient for use;

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The present application discloses a flow-inoculation feeding device, referring to Figure 1-3, including a ladle 1 and a gate 2, support plates 3 are fixed on both sides of the gate 2, and a rotating rod 4 is passed through the top of the two support plates 3, and the rotating rod 4 is rotatably connected to the corresponding support plate 3. The inner sides of the two rotating rods 4 are fixedly connected to the inoculant storage hopper 5, and one of the rotating rods 4 passes through the support plate 3 and is fixedly connected to the first gear 6. The bottom of the first gear 6 is engaged with the second gear 7. One side of the second gear 7 passes through the support plate 3 and is rotated to be connected to the support plate 3, and the other end is connected to the output shaft of the rotating motor 8. The rotating motor 8 rotates, thereby driving the second gear 7 and the first gear 6 to rotate, so that the inoculant storage hopper 5 rotates and aligns with the ladle 1 for easy use. A tightening mechanism 9 is provided on the top of the inoculant storage hopper 5;

[0027] The tightening mechanism 9 includes a sealing plate 91, an electric telescopic rod 92, a spring 93 and a bracket 94. The top of the inoculant storage hopper 5 is fitted with a sealing plate 91. The top of the sealing plate 91 is fixedly connected to the electric telescopic rod 92. A spring 93 is sleeved on the thin end of the electric telescopic rod 92. The end of the electric telescopic rod 92 away from the sealing plate 91 is fixedly connected to the bracket 94. The electric telescopic rod 92 extends when the inoculant storage hopper 5 rotates, squeezing the sealing plate 91 so that the sealing plate 91 squeezes the inoculant inside the inoculant storage hopper 5 to prevent the inoculant from tipping over, so that the inoculant is always at the bottom of the inoculant storage hopper 5, which is convenient for discharging.

[0028] Reference Figure 1-2 A counterweight block 10 is provided around the outer side of the bottom of the inoculant storage hopper 5 , and a discharge port 11 is fixed at the bottom of the inoculant storage hopper 5 , and the discharge port 11 corresponds to the gate 2 .

[0029] Reference Figure 1-3 The bracket 94 is fixedly arranged on one side of the inoculant storage hopper 5. The bottom of the sealing plate 91 is surrounded by an extension edge 12, which is convenient for the sealing plate 91 to push the inoculant to the middle of the inoculant storage hopper 5 when the sealing plate 91 is squeezed downward, so as to facilitate rapid extrusion and flattening. A pressure sensor 13 fixedly connected to the sealing plate 91 is provided on the inner side of the extension edge 12. The pressure sensor 13 can sense the pressure at the bottom of the sealing plate 91, and then control the extension and contraction of the electric telescopic rod 92. A controller 14 is fixed on one side of the ladle 1. The controller 14 is electrically connected to the pressure sensor 13, and the electric telescopic rod 92 is electrically connected to the controller 14.

[0030] The implementation principle of a flow-inoculation feeding device in the embodiment of the present application is as follows:

[0031] During use, when the ladle 1 is tilted, the inoculant storage hopper 5 remains vertically downward under the action of gravity, aligned with the gate 2, and inoculant is added to the gate 2. When the ladle 1 rotates at too large an angle, the discharge port 11 of the inoculant storage hopper 5 cannot be aligned with the gate 2, and the rotating motor 8 is started by the controller 14, so that the second gear 7 drives the first gear 6 to rotate, thereby driving the inoculant storage hopper 5 to rotate, so that the discharge port 11 is aligned with the gate 2. During use, the controller 14 controls the electric telescopic rod 92 to extend, so that the sealing plate 91 squeezes the inoculant in the inoculant storage hopper 5, so that the inoculant accumulates at the bottom of the inoculant storage hopper 5 and does not tilt, thereby improving the uniformity of inoculant addition.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, principle and application direction of the present application should be included in the scope of protection of the present application.
