It is also called a ceramic stopper rod. It consists of a rod core, a sleeve brick and a plug brick. The rod core is usually made of ordinary carbon steel round steel with a diameter of 30 to 60 mm. The stopper rod can be divided into a combined stopper rod and an integral stopper rod. The combined stopper rod is made of a sleeve brick and a plug connected in series with a steel pipe. Due to the many joints and installation reasons of this rod, molten steel and slag can easily corrode the joints, causing the rod to break or the plug to fall off, and the accident rate is high. The integral stopper rod, that is, the rod body and the plug are directly connected together without a joint. However, the existing integral stopper rod cannot protect the surface when in use. When pouring steel, the surface of the integral stopper rod will be subjected to thermal shock and severe erosion, which can easily cause the middle part of the integral stopper rod to break, and the service life is relatively low. At the same time, the integral stopper rod cannot be guided for insertion, which can easily cause the integral stopper rod to tilt. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6 The utility model provides a technical solution: an anti-corrosion integral stopper rod, comprising a main body 10, a positioning plate 20, a sleeve 201, a transverse plate 202, a groove 203, a gasket 204, a hole 1 30, a hole 2 301, a baffle 302, a drainage groove 303, a drainage cavity 304 and a filter plate 305;

[0032] The integral stopper rod can reduce corrosion to the main body 10, and the specific implementation is as follows:

[0033] The main body 10 is configured as a cylindrical structure, and a positioning plate 20 is connected to one side of the surface of the main body 10; a protective structure is configured on the surface of the main body 10, and the protective structure includes: a sleeve 201 is sleeved and installed on the surface of the main body 10, and a transverse plate 202 is fixedly connected to one side surface of the sleeve 201, a groove 203 is embedded in one side surface of the transverse plate 202, and a gasket 204 is connected to the surface of the transverse plate 202, the main body 10 and the sleeve 201 are in sliding connection, the transverse plate 202 and the main body 10 are in sliding connection, the gasket 204 and the groove 203 are symmetrically arranged on the surface of the transverse plate 202, the positioning plate 20 and the groove 203 are correspondingly arranged, and the groove 203 and the positioning plate 20 are in a snap-fit ​​connection.

[0034] Move the horizontal plate 202 so that the bottom of the horizontal plate 202 fits with the surface of the mounting surface. At this time, the horizontal plate 202 drives the bottom of the gasket 204 to fit with the surface of the mounting surface. The horizontal plate 202 can be perpendicular to the mounting surface. At this time, the horizontal plate 202 drives the sleeve 201 to be inserted into the interior of the mounting surface. At this time, press the main body 10 downward, as shown in FIG. Figure 1 At this time, the main body 10 moves downward inside the cross plate 202 and the sleeve 201, so that the main body 10 is exposed from the bottom of the sleeve 201, and the main body 10 can be moved vertically downward so that the main body 10 is inserted into the inside of the installation surface. The main body 10 drives the positioning plate 20 to move downward. When the positioning plate 20 moves to the inside of the groove 203, the groove 203 engages with the positioning plate 20. At this time, the main body 10 no longer moves downward. At this time, the cross plate 202 and the positioning plate 20 can be fixed to the surface of the installation surface by screws. At this time, the sleeve 201 can protect the surface of the main body 10 to prevent the middle part of the main body 10 from breaking.

[0035] The integral stopper rod prevents impurities from entering the interior of the hole 30. The specific implementation method is as follows:

[0036] An anti-backflow mechanism is provided inside the main body 10, and the anti-backflow mechanism includes: a hole 1 30 is embedded in the inside of the main body 10 and the positioning plate 20, and a hole 2 301 is embedded in one side of the main body 10, a filter plate 305 is fixedly connected to the inner wall of the hole 2 301, and a baffle 302 is symmetrically fixedly connected to the inner wall of the hole 2 301, a drainage groove 303 is embedded in the surface of the baffle 302, and a drainage cavity 304 is symmetrically embedded in the inside of the main body 10, the hole 1 30 and the hole 2 301 are through-connected, and one side of the bottom of the main body 10 is set in an arc shape, and the hole 2 301 is set on the arc-shaped side of the main body 10, the baffle 302 is set at the bottom of the filter plate 305, and the surface of the baffle 302 is set as an inclined plane, the end of the drainage groove 303 is set corresponding to the position of the drainage cavity 304, and the drainage cavity 304 and the drainage groove 303 are through-connected.

[0037] When the air flow enters and moves upward from the bottom of hole 2 301, the gas drives the impurities upward. At this time, the gas drives the impurities to move to the filter plate 305. The filter plate 305 can adsorb the impurities and filter the air to prevent the impurities from moving upward. The filtered air continues to move upward and moves to the inside of hole 1 30 through hole 2 301. The impurities are adsorbed on the bottom of the filter plate 305. When the gas impacts the filter plate 305, the impurities at the bottom of the filter plate 305 fall down. At this time, the impurities fall on the surface of the baffle 302 and move downward along the bottom of the baffle 302. At this time, the impurities pass through the baffle 302 into the inside of the drainage groove 303, and enter the drainage cavity 304 along the drainage groove 303. The impurities are discharged from the inside of the main body 10 through the drainage cavity 304.

[0038] Working principle: When using the corrosion-resistant integral stopper rod, a positioning plate 20, a sleeve 201 and a cross plate 202 are provided to reduce corrosion to the main body 10. A baffle 302, a drainage groove 303, a drainage cavity 304 and a filter plate 305 are provided to prevent impurities from entering the interior of the hole 30, thereby increasing the overall practicality.
