Technical Field
[0001] This utility model relates to the field of refining slag production technology, and in particular to a pre-melted refining slag proportioning and weighing device. Background Technology
[0002] Pre-melted refining slag refers to refining slag made by mixing raw materials in a certain proportion, melting them into a liquid state at a high temperature above the melting point of the slag system in specialized equipment, and then cooling and crushing them for use in steelmaking. Pre-melted refining slag has high purity, uniform chemical composition, stable phase, low melting point, and fast slag formation speed, which can significantly shorten refining time and can be directly used for slag washing during the tapping process of converter steel ladles to improve the cleanliness of molten steel. In the production of pre-melted refining slag, it is necessary to weigh and proportion the raw materials to obtain accurate data for subsequent production.
[0003] Chinese patent discloses a pre-melted refining slag proportioning and weighing machine (publication number CN216726855U). This patented technology includes a base plate, with a stirring device support frame fixedly installed on the top of the base plate. A mixing tank is mounted on the stirring device support frame via bearings, and a gear ring is sleeved on the outer side of the mixing tank. A stirring motor is mounted on the left side of the stirring device support frame via a motor mounting compartment. A gear is fixedly mounted on the output shaft of the stirring motor, meshing with the gear ring. A weighing device mounting frame is fixedly installed on the top of the stirring device support frame, and a weighing device and a flow guiding device are fixedly installed on the weighing device mounting frame. A lifting gantry frame is fixedly installed on the top of the base plate, and the lifting gantry frame is slidably mounted on the batching bin assembly via a slide groove and a lifting slider. After proportioning and weighing, this device can directly stir and mix the materials. The mixed materials are directly conveyed to the slag furnace via a conveyor belt, effectively saving intermediate transfer links and improving work efficiency.
[0004] However, most existing proportioning and weighing methods rely on stirring rods within the mixing drum. This method fails to effectively agitate the raw materials between the stirring rods, and the materials tend to adhere to the drum wall, resulting in losses. For example, the aforementioned prior art uses a weighing and stirring method. In practical applications, when the proportioned refining slag raw materials are stirred within the mixing drum, they cannot be adequately agitated, affecting subsequent use. Therefore, those skilled in the art have provided a pre-melted refining slag proportioning and weighing device to address the problems mentioned in the background art. Utility Model Content

[0023] Please see Figure 1-4This utility model provides a technical solution for a pre-melted refining slag proportioning and weighing device, comprising: a proportioning and weighing platform 1, a proportioning and weighing cylinder 2 provided on the upper surface of the proportioning and weighing platform 1, a bottom sleeve 21 threadedly connected to the outside of the proportioning and weighing cylinder 2, and a bracket 3 bolted to the outside of the proportioning and weighing cylinder 2, a stirring motor 31 installed on the upper surface of the bracket 3, a rotating shaft 32 connected to the drive end of the stirring motor 31, a first stirring rod 33 and a second stirring rod 34 respectively provided on the outside of the rotating shaft 32 from left to right, and a scraper 35 connected to one end of the first stirring rod 33 and the second stirring rod 34. This arrangement utilizes the operation of the stirring motor 31 to make the first stirring rod 33 and the second stirring rod 34 outside the rotating shaft 32 stir the refining slag raw material inside the proportioning and weighing cylinder 2, and the scraper 35 can be used to scrape off the raw material on the inner wall of the proportioning and weighing cylinder 2.
[0024] A rear plate 6 is installed on the rear surface of the weighing platform 1. From left to right, a first storage box 4 and a second storage box 5 are respectively arranged on the front surface of the rear plate 6. The rear surfaces of the first storage box 4 and the second storage box 5 are both provided with mounting plates 51. A movable plate 7 is also provided on the rear surface of the rear plate 6. Two limiting rods 72 are symmetrically arranged on the front surface of the movable plate 7. This arrangement utilizes the sliding of the mounting plate 51 inside the mounting groove 61 to achieve quick installation of the first storage box 4 and the second storage box 5, so as to facilitate quick replacement.
[0025] like Figure 2 As shown, the front surface of the rear plate 6 is provided with an installation groove 61, and the installation plate 51 slides inside the installation groove 61 in a "T" shape. The lower surfaces of the first storage box 4 and the second storage box 5 are provided with discharge pipes above the proportioning weighing cylinder 2. The lower surfaces of the first storage box 4 and the second storage box 5 are provided with guide plates inclined below the discharge pipes. This arrangement utilizes the sliding of the installation plate 51 inside the installation groove 61 to realize the installation and disassembly of the first storage box 4 and the second storage box 5. The guide plates can guide the raw materials discharged from the discharge pipes to the proportioning weighing cylinder 2 for proportioning.
[0026] like Figure 2 and Figure 3 As shown, a cylinder 71 is installed at the middle position of the rear surface of the rear plate 6. The telescopic end of the cylinder 71 is connected to the middle position of the front surface of the movable plate 7. A limit hole is opened on the rear surface of the mounting plate 51. The front end of the limit rod 72 is embedded in the interior of the limit hole. This setting uses the operation of the cylinder 71 to make the movable plate 7 move, and when it moves, the limit rod 72 will be embedded in the interior of the limit hole, thus achieving the purpose of positioning the mounting plate 51.
[0027] like Figure 1 and Figure 4As shown, the first stirring rod 33 and the second stirring rod 34 are staggered on the outside of the rotating shaft 32.

[0028] The working principle of this utility model is as follows: When using the pre-melted refining slag proportioning and weighing device, the first storage box 4 and the second storage box 5 are first slidably mounted inside the mounting groove 61 via the mounting plate 51. This allows the first storage box 4 and the second storage box 5 to be mounted on the front surface of the rear plate 6. After installation, the operation of the cylinder 71 causes the moving plate 7 to move. During this movement, one end of the limiting rod 72 is inserted into the limiting hole on the rear surface of the mounting plate 51. This allows the first storage box 4 and the second storage box 5 to be mounted on the rear surface of the rear plate 6. Opening the first... The discharge pipes on the lower surfaces of the first storage bin 4 and the second storage bin 5 can discharge the raw materials inside to the proportioning weighing cylinder 2 for proportioning. During proportioning, the stirring motor 31 on the support 3 is started, which makes the first stirring rod 33 and the second stirring rod 34 outside the rotating shaft 32 efficiently stir and mix the raw materials inside the proportioning weighing cylinder 2. The scraper 35 can be used to clean the inner wall of the proportioning weighing cylinder 2. It is practical. After stirring and mixing, the bottom sleeve 21 can be separated from the proportioning weighing cylinder 2 to achieve the purpose of rapid material discharge.
