TECHNICAL FIELD

[0001] The application relates to the technical field of tundish stopper production equipment, in particular to a refractory coating device for the inner hole of a tundish stopper. BACKGROUND

[0002] The tundish stopper is a key component for controlling the flow of molten steel in the continuous casting process, and its working environment is harsh, and it needs to withstand the scouring and erosion of high-temperature molten steel. In order to improve the service life and performance of the stopper, refractory coating is usually applied to the inner hole surface.

[0003] However, the existing coating device has many problems when coating and drying the inner hole of the stopper. For example, some devices cannot uniformly coat the inner hole of the stopper, resulting in inconsistent coating thickness and affecting the overall performance of the stopper; and some drying devices cannot effectively and uniformly dry the inner hole, resulting in insufficient drying of the coating and easy cracking and peeling.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] like Figures 1-3 As shown, a refractory coating device for the inner hole of a stopper rod in an intermediate package includes: a linear drive assembly is provided on the housing 1, and a bearing plate 5 is fixedly connected to the output end of the linear drive assembly;

[0028] The two ends of the support plate 5 are connected to adjustable support seats 6 by fasteners. The support seats 6 are respectively provided with paint pipe conduit 7 and air pipe conduit 11.

[0029] The paint pipe 8 is inserted through the paint pipe conduit 7, and the end is connected to the paint distributor 9 which is equipped with atomizing nozzles 10 in a circumferential direction;

[0030] The trachea 12 passes through the tracheal tube 11 and is connected at the end to a gas splitter 13 with a circumferentially oriented guide head 14. The guide head 14 has a guide airway 15.

[0031] Specifically,

[0032] Furthermore, the linear drive assembly includes: synchronous pulleys 2, there are two synchronous pulleys 2, which are disposed inside the housing 1, and the motor 20 is fixed to the outer wall of the housing 1 and drives the synchronous pulleys 2 to rotate;

[0033] A timing belt 3 is arranged around a timing pulley 2, and a connecting block 4 for connecting to a bearing plate 5 is fixedly connected to its bottom.

[0034] Specifically, the bottom opening of the housing 1 avoids the connecting block 4. The synchronous belt 3 uses the connecting block 4 to drive the bearing plate 5 to move horizontally, which can simultaneously move the two bearing seats 6, so that the paint tube 7 and the air tube 11 on the bearing seat 6 can simultaneously enter and exit the inner hole of the stopper rod, and simultaneously apply paint and dry the paint.

[0035] Furthermore, the slide bar 16 is slidably mounted on the bearing seat 6, and its two ends are connected to the belt conveyor 21 through the mounting plate 17. The belt conveyor 21 is equipped with a rubber belt 22 with a stopper groove 23.

[0036] Specifically, when the support seat 6 is moved by the support plate 5, the support seat 6 slides on the slide rod 16, so that the slide rod 16 can guide the displacement of the support seat 6 and keep it in linear displacement.

[0037] Furthermore, the bearing plate 5 is provided with a bearing seat positioning groove 19, and the bearing seat 6 adjusts the guide tube spacing by adjusting the position of the fasteners in the positioning groove.

[0038] Furthermore, the atomizing nozzles 10 are evenly distributed around the paint distributor 9, with adjacent nozzle axes forming an angle of 30-60°.

[0039] Furthermore, the inner surface of the stopper groove 23 is provided with anti-slip texture, and the groove depth is 1 / 4 to 1 / 3 of the stopper diameter.

[0040] Specifically, the belt conveyor 21 and the rubber belt 22 are existing technologies. By setting a stopper groove 23 on the rubber belt 22, the stopper placed therein is prevented from rolling, and the inner hole of the horizontally placed stopper can face the paint pipe duct 7 and the air pipe duct 11, which facilitates the application of paint and drying.

[0041] Furthermore, the mounting plate 17 is provided with a slide rod positioning groove 18, and the installation position of the slide rod 16 is adjusted by fasteners.

[0042] Specifically, when it is necessary to adjust the distance between the coating tube 7 and the tracheal tube 11, loosen the fasteners of the fixed support 6 and the slide rod 16, then adjust the distance between the coating tube 7 and the tracheal tube 11, and then fix the support 6 and the slide rod 16 with the fasteners after the adjustment is completed.

[0043] Furthermore, the air outlet of the air guide duct 15 is oriented at an angle of 15-45° toward the rear of the air tube 12 so as to blow hot air out of the inner hole.

[0044] In the above structure, the belt conveyor 21 is powered on, and the intermediate bag stopper is placed horizontally in the stopper groove 23. The intermediate bag stopper is transported by the rubber belt 22. The motor 20 is powered on, driving the synchronous pulley 2 to rotate. The synchronous belt 3 drives the connecting block 4 to move back and forth, so that the paint distributor 9 and the gas distributor 13 can enter and exit the inner hole of the intermediate bag stopper. After entering the inner hole, the feeding equipment is started to pump the paint into the paint pipe 8, and then spray it from the atomizing nozzle 10 to the inner hole wall. The hot air equipment sends hot air into the air pipe 12, and then the hot air enters the gas distributor 13 and is sprayed out from the guide head 14. After being guided by the guide head 14, the hot air flows out of the hole, which accelerates the drying of the paint and realizes continuous coating and drying.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed. The scope of protection of this application is defined by the appended claims and their equivalents.
