The protective side plates 2 are perpendicular to the protective bottom plate 1, and the two protective side plates 2 are symmetrically arranged about the center line of the protective bottom plate 1. One end of the two protective side plates 2 is parallel, and the other end is inclined toward each other, that is, one end of the two protective side plates 2 is inclined toward the other protective side plate 2, so that the two protective side plates 2 are inclined as a whole, and a certain gap is retained at the ends of the two protective side plates 2 facing each other.
[0038] An inlet 4 is formed at one end of the two protective side panels 2 that are parallel to each other, and an outlet 5 is formed at one end of the two protective side panels 2 that face each other, so the width of the inlet 4 is greater than the width of the outlet 5. A flow channel 3 is formed in the middle of the two protective side panels 2, and the inlet 4 and the outlet 5 can be connected through the flow channel 3. The side edge of the protective bottom plate 1 is in contact with the protective side edge, so the overall shape of the protective bottom plate 1 is an isosceles trapezoid.
[0039] After the overflow port protection device provided by the present invention is embedded in the overflow port, the glass liquid flows from the inlet 4 to the protective bottom plate 1, and flows along the flow channel 3 to the outlet 5 under the constraint and guidance of the protective side plates 2 on both sides, and finally flows to the outside through the outlet 5.

The protective portion 22 is inclined, and the above-mentioned flow channel 3 is formed between the two protective portions 22.
[0052] The end of the protective bottom plate 1 near the inlet 4 is integrally formed with a liquid inlet step 11, which is inclined downward in a direction away from the inlet 4, and the two ends of the liquid inlet step 11 are tightly pressed against the inner side wall of the insertion portion 21 of the protective side plate 2. The end of the protective bottom plate 1 near the outlet 5 is integrally formed with a liquid outlet step 12, which is inclined downward in a direction away from the outlet 5, and the two ends of the liquid outlet step 12 are tightly pressed against the inner side wall of the slow flow portion 23 of the protective side plate 2.

The highest of the blocking sheets 6 shall not exceed the height of the protective side plates 2.
[0054] Reference Figure 3 and Figure 4 The present disclosure also provides a kiln brick, on which an inner inlet flow channel 7 and an outer flow channel 8 are provided, which are connected to each other for the glass liquid to flow out. The width of the inner inlet flow channel 7 is greater than the width of the outer flow channel 8. The above-mentioned overflow port protection device is provided at the connection point between the inner inlet flow channel 7 and the outer flow channel 8.
