Description

Technical Field

[0001] This utility model belongs to the field of cast iron technology, specifically relating to an anti-splashing, sealed automatic inoculant adding device for molten iron. Background Technology

[0002] Iron inoculant is a chemical substance added to molten iron during the cast iron production process, primarily used to improve the microstructure and properties of cast iron.

[0003] Chinese patent CN217192461U discloses a device for adding inoculant in a flow path. The specification describes a device that uses a weighing sensor to weigh the molten iron inside a ladle, with a touch-screen controller performing proportional calculations for increased convenience. A second electric valve allows molten iron to be poured into the ladle, at which point the touch-screen controller calculates the required inoculant weight and controls the opening of the first electric valve to allow the inoculant to fall into the feeding hopper. A tensile weighing device then weighs the inoculant in the feeding hopper. When the weight reaches the required proportion, the touch-screen controller closes the first electric valve and simultaneously opens the second electric valve, allowing the inoculant in the feeding hopper to fall into the ladle, achieving fully automatic inoculant addition. A scale label facilitates observation of the inoculant stored in the feeding hopper by the operator.

[0004] In the aforementioned application, the inoculant is poured directly into the molten iron ladle from a high position. The impact force when the inoculant enters the molten iron is relatively large, which can easily cause the molten iron to splash. Furthermore, if the addition speed is too fast, a large amount of inoculant will enter the molten iron in a short period of time, which will also cause the molten iron to churn violently and splash. Utility Model Content

[0005] The purpose of this invention is to provide an anti-splashing, sealed automatic inoculant adding device for molten iron, so as to solve the problem in the prior art that molten iron is easily splashed when adding inoculant.

[0013] Preferably, the cross-sectional shape of the two first protrusions at one end away from each other is triangular, and the two first protrusions are respectively located below the two second protrusions.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model allows for adjustment of the cover plate position by sliding the slide rod. The cover plate blocks the top of the molten iron ladle, thus preventing splashing of molten iron when adding inoculant. Furthermore, with the help of the connecting pipe, the inoculant can be added to the molten iron ladle normally without being affected by the movement of the cover plate.

[0016] 2. In this utility model, when the first and second protrusions are pressed, the second protrusion can slide, and with the help of the spring force, the position of the cover plate can be stabilized, so that the cover plate does not stick to the molten iron ladle.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 As shown, this utility model provides an anti-splash, sealed automatic inoculant addition device for molten iron, including a base plate 1, a fixing frame 101 fixedly connected to the end face of the base plate 1, a molten iron ladle 102 provided on the end face of the base plate 1, a storage tank 103 installed on the end face of the fixing frame 101, an auxiliary mechanism 2 provided on the surface of the fixing frame 101, the auxiliary mechanism 2 including two sliding rods 201 slidably inserted into the surface of the fixing frame 101, a cover plate 202 fixedly connected to one end of the two sliding rods 201 near the base plate 1, a round tube 203 connected to the end face of the cover plate 202, a conduit 205 connected to the bottom of the storage tank 103, and a connecting pipe 204 connected to one end of the round tube 203 and the conduit 205 that are close to each other.

[0024] In this embodiment, the connecting pipe 204 is a telescopic pipe so that the connecting pipe 204 is not affected when the cover plate 202 moves, and does not cause movement interference.

[0025] In an optional embodiment: the top of the conduit 205 passes through the fixing frame 101, and a valve 207 is installed on the arc surface of the conduit 205. The valve 207 is a solenoid valve.

[0026] It should be noted that by energizing valve 207, the inoculant in storage tank 103 can be automatically released.

[0027] In an optional embodiment: a handle 206 is fixedly connected to the arc surface of the cover plate 202, and the bottom surface of the cover plate 202 is in contact with the end face of the molten iron ladle 102.

[0028] It should be noted that the handle 206 serves to facilitate the movement of the cover plate 202.

[0029] In an optional embodiment: First protrusions 209 are fixedly connected to the arc surfaces of both slide rods 201. Rectangular holes 208 are provided on both sides of the inner wall of the fixing bracket 101. Springs 211 are fixedly connected to the inner walls of both rectangular holes 208. Second protrusions 210 are fixedly connected to the ends of the two springs 211 that are close to each other. The cross-sectional shape of the end of the second protrusion 210 away from the spring 211 is triangular. The cross-sectional shape of the ends of the two first protrusions 209 that are far from each other is triangular, and the two first protrusions 209 are respectively located below the two second protrusions 210.

[0030] It should be noted that when the first protrusion 209 and the second protrusion 210 are pressed, the second protrusion 210 can slide. With the help of the elastic force of the spring 211, the position of the cover plate 202 can be stabilized, so that the cover plate 202 does not stick to the molten iron ladle 102.

[0031] The working principle of this utility model is as follows: During use, the operator pulls down the handle 206, causing the cover plate 202 to move downwards. The two sliding rods 201 slide along the surface of the fixing frame 101. The two first protrusions 209 first press against the two second protrusions 210. After being pressed, the second protrusions 210 contract, and the spring 211 is compressed until the first protrusions 209 pass over the second protrusions 210. Finally, the cover plate 202 covers the ladle 102. Figure 2 As shown, when the cover plate 202 moves, the connecting pipe 204 will extend, and then by opening the valve 207, the inoculant inside the storage tank 103 will fall into the molten iron ladle 102 to complete the addition. During this process, the molten iron in the molten iron ladle 102 will not splash to the outside.
