Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective slag slurry mixing, and in particular to a slurry mixing device for producing protective slag. Background Technology
[0002] Currently, all continuous casting processes use protective slag. Protective slag serves several functions, including heat insulation, air isolation, prevention of secondary oxidation of molten steel, purification of the steel-slag interface, adsorption of inclusions in the molten steel, lubrication of the billet shell, and improvement of solidification heat transfer. In actual continuous casting production, protective slag is generally produced through spray granulation. Spray granulation involves fluidizing, dust removal, atomizing, and solidifying the material. To ensure good uniformity of the produced protective slag product, a stirring device is usually installed before spray granulation to agitate the slurry, making it more uniform and thus guaranteeing the uniformity of the protective slag product. In practice, after agitation, residual slurry adheres to the inner wall of the agitation chamber, wasting resources and increasing the cleaning steps required, leading to time-consuming and labor-intensive technical problems. Utility Model Content
[0003] One objective of this invention is to provide a slurry mixing device for producing protective slag that at least solves any of the aforementioned technical problems.
[0004] A further objective of this invention is to avoid slurry residue inside the mixing chamber.
[0005] Another further objective of this invention is to improve the mixing effect and reduce the cleaning steps required inside the mixing chamber.
[0006] In particular, this utility model provides a slurry mixing device for producing protective slag, including a mixing tank;
[0007] A stirring mechanism is provided, which has a stirring rod and a symmetrically arranged stirring frame at the lower end of the stirring rod; a bearing and a fixing rod are provided on the inner side of the stirring frame, the bearing is fixedly connected to the stirring frame through the fixing rod, a rotating shaft is provided inside the bearing, a rotating shaft block is provided at one end of the rotating shaft, a top cap is provided at the other end, and stirring blades are provided on the rotating shaft block;
[0008] A scraper is disposed on one side of the mixing frame, and the middle part of the scraper is fixedly connected to the pressure rod, which is movably connected to the mixing frame.
[0009] Furthermore, the stirring rack is movably connected to the pressure rod at two-tenths of its length.
[0010] Furthermore, the stirring rack is provided with a pad, and the side of the pad near the pressure rod is provided with a movable groove for mounting the pressure rod.
[0011] Furthermore, the stirring blades are inclined, and the inclination angle is 30°-60°.
[0012] Furthermore, the end of the pressure bar away from the scraper is located at the rear end of the top cap.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] This invention utilizes rotatable bearings and rotating shaft blocks between the mixing racks. When the mixing rod rotates, it drives the mixing rack to rotate. As the mixing rack rotates, the material passes through it, and the slurry pushes the mixing blades to rotate, causing the blades to agitate the slurry and thus ensuring uniform mixing. Simultaneously, a pressure rod and scraper are provided on one side of the mixing rack. The pressure rod and the mixing rack are connected to form a lever. When the scraper contacts the inner wall of the cleaning cylinder, the other end of the pressure rod abuts against the rear end of the top cap, thereby cleaning the stains at the rear of the top cap.

[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.

[0024] This embodiment provides a slurry mixing device for producing protective slag, including a mixing tank 1, a mixing mechanism 2, and a scraper 208. The mixing mechanism 2 has a mixing rod 201 extending into the mixing tank 1. Figure 4 As shown, a symmetrically arranged stirring frame 202 is provided at the lower end of the stirring unit. The stirring frame 202 has a trapezoidal cross-section. A bearing 210 and a fixing rod 209 are provided on the inner side of the stirring frame 202. The bearing 210 is fixedly connected to the stirring frame 202 through the fixing rod 209. A rotating shaft is provided inside the bearing 210. A rotating shaft block 205 is provided at one end of the rotating shaft, and a top cap 206 is provided at the other end. During use, the rotating shaft can extend and retract a short distance within the bearing 210. Stirring blades 203 are provided on the rotating shaft block 205, and the stirring blades 203 are arranged in a circular array around the rotating shaft block 205. A scraper 208 is provided on one side of the stirring frame 202, and the middle part of the scraper 208 is fixedly connected to a pressure rod 207. The pressure rod 207 is movably connected to the stirring frame 202. Figure 4 and Figure 5 As shown, the pressure rod 207 and the pad 211 are in a lever state. The stirring frame 202 is movably connected to the pressure rod 207 at two-tenths of its length. During use, the rotation of the stirring rod 201 drives the stirring blades 203 set between the stirring frames 202 to rotate, thereby realizing the stirring of the slurry. At the same time, when the rotating shaft is subjected to force and moves, it drives the top cap 206 to move. The end of the pressure rod 207 away from the scraper 208 is located at the rear end of the top cap 206. When the top cap 206 moves, it causes one end of the pressure rod 207 to be subjected to force, thereby improving the cleaning effect of the scraper 208. At the same time, one end of the pressure rod 207 can clean the stains at the rear of the top cap 206.
[0025] It should be further explained that a pad 211 is provided on the stirring rack 202, and a movable groove 204 for installing the pressure rod 207 is provided on the side of the pad 211 near the pressure rod 207, and the pressure rod 207 is installed in the movable groove 204.
[0026] It should be further noted that the stirring blades 203 are inclined, and the inclination angle is 30°-60°, which can be adapted according to the usage and the condition of the slurry.
[0027] It should be further noted that the rotating shaft can be replaced with a drive motor, which drives the rotating blades to rotate.
[0028] Working principle of this utility model:
[0029] In use, a rotatable bearing 210 and a rotating shaft block 205 are provided between the mixing racks 202. When the mixing rod 201 rotates, it drives the mixing rack 202 to rotate. When the mixing rack 202 rotates, the material passes through the mixing rack 202. When passing through the mixing rack 202, the slurry pushes the mixing blades 203 to rotate, so that the blades stir between the slurry, thereby making the slurry evenly mixed. At the same time, a pressure rod 207 and a scraper 208 are provided on one side of the mixing rack 202. The pressure rod 207 and the mixing rack 202 are connected to form a lever state. When the scraper 208 contacts the inner wall of the cleaning cylinder of the mixing tank 1, the other end of the pressure rod 207 abuts against the rear end of the top cap 206, thereby cleaning the stains on the rear of the top cap 206.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
