[0020] 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.

[0021] According to an embodiment of the present invention, an anti-clogging integral breathable brick is provided.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figs. 1-3 As shown, an anti-clogging integral permeable brick according to an embodiment of the present invention includes a permeable brick core 1 and a seat brick 2 installed around it. The seat brick 2 is arranged around the permeable brick core 1, and refractory coating 4 is filled between the seat brick 2 and the permeable brick core 1. A hollow steel disc 5 is embedded in the bottom of the permeable brick core 1, and a venting pipe 6 is connected to the bottom of the hollow steel disc 5. The bottom of the venting pipe 6 extends to the outside of the seat brick 2. Two air inlet channels 3 are opened inside the permeable brick core 1, and both air inlet channels 3 are connected to the hollow steel disc 5. Two inclined baffles are welded inside the hollow steel disc 5. Plate 7, and several vents 8 are arranged side by side on the upper part of the two inclined baffles 7. The top surface of the ventilated brick core 1 is fixed with an I-shaped seat 11, and a connecting block 12 is installed on the I-shaped seat 11. A circular baffle 10 is welded on the connecting block 12 corresponding to the air inlet channel 3. The vent pipe 6 is connected to an external gas storage device. Argon gas can be used to prevent the molten steel in the furnace from being oxidized and contaminated. In order to facilitate the installation of the ventilated brick core 1, a conical cavity is opened inside the seat brick 2. After the ventilated brick core 1 is installed into the conical cavity, the bottom of the ventilated brick core 1 is sealed with refractory material.

[0023] In one embodiment, the two inclined baffles 7 are symmetrical about the vertical centerline of the hollow steel disc 5, and the two inclined baffles 7 are distributed on the left and right sides of the vent pipe 6. By setting the two inclined baffles 7, the blockages entering through the two air intake channels 3 can be blocked.

[0024] In one embodiment, the top surface of the hollow steel disc 5 has two air holes 9, and the two air holes 9 correspond one-to-one with the two air inlet channels 3. The air holes 9 are provided to keep the hollow steel disc 5 connected to the two air inlet channels 3.

[0025] In one embodiment, the upper surface of the inclined baffle 7 is provided with a number of through holes, and the number of through holes corresponds one-to-one with a number of vents 8. By setting the inclined baffle 7, a small amount of blockage material can be prevented from entering the vent pipe 6 and causing blockage. By setting the number of vents 8, the smoothness of air intake can be maintained when a small amount of blockage material enters the vent pipe 6.

[0026] In one embodiment, a round rod is provided in the middle of the I-shaped base 11, and a connecting hole is provided on the surface of the connecting block 12 corresponding to the round rod. The round rod is inserted into the connecting hole of the connecting block 12, so that the circular baffle 10 can be rotated so that it can be automatically opened during the air intake stage to facilitate air intake.

[0027] In one embodiment, the end of the permeable brick core 1 with the circular baffle 10 extends to the top of the seat brick 2. By the part of the permeable brick core 1 protruding from the seat brick 2, the height of the two air intake channels 3 is higher than that of the seat brick 2, thereby preventing impurities or other blockages from entering the air intake channels 3 to a certain extent, and protecting the circular baffle 10 from corrosion by molten steel.

[0028] Working principle:

[0029] In use, two air inlet channels 3 are opened inside the permeable brick core 1, penetrating the hollow steel disc 5. A circular baffle 10 is rotatably connected to the air inlet channel 3 on the top surface of the permeable brick core 1 using an I-shaped base 11 and a connecting block 12. When air is introduced, the gas enters the hollow steel disc 5 at the bottom of the permeable brick core 1 through the vent pipe 6, and then is introduced into the two air inlet channels 3 through the air hole 9. As the air pressure inside the air inlet channel 3 increases, the circular baffle 10 is lifted up, realizing the air intake of the furnace body. When one air inlet channel 3 is blocked, the other air inlet channel 3 can maintain normal air intake, achieving the purpose of preventing blockage of the furnace body air intake. By setting an inclined baffle 7 and a vent 8 inside the hollow steel disc 5, the inclined baffle 7 can block the blockage entering the hollow steel disc 5, while the vent 8 located above the inclined baffle 7 keeps the gas flowing smoothly, further ensuring the anti-blockage effect.

[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.
