Description

Technical Field

[0001] The utility model relates to the technical field of cooling the temperature of magnesia carbon bricks, in particular to a magnesia carbon brick cooling device capable of adjusting the air outlet angle. Background Art

[0002] Nowadays, magnesia carbon bricks, as a composite refractory material, have been widely used in steelmaking enterprises around the world. Magnesia carbon bricks are made by mixing the refractory ingredients in a certain proportion, and then using a hydraulic brick press to press and form the magnesia carbon brick refractory products. After that, the bricks are stacked and sent to the drying kiln for drying. After drying, the magnesia carbon bricks can be directly coated and packaged to form finished products. Usually, the drying kiln is arranged side by side in a long and thin strip. The magnesia carbon bricks should be heated to about 200 degrees Celsius in the drying kiln for more than ten hours, and then stop heating and place in the kiln for about 6 hours. The magnesia carbon bricks after drying out of the kiln still retain a certain temperature. If the temperature is high, the plastic film will be softened and shrink and deformed when the magnesia carbon bricks are coated directly after leaving the kiln. The distorted plastic film has poor appearance, and in severe cases, the plastic film will be damaged by scalding, resulting in partial failure of the plastic film protection. If the magnesia carbon bricks are dried out of the kiln and the natural cooling time is at least several hours, the site area for turnover transportation out of the kiln will increase, and the large area occupied by natural cooling will cause great inconvenience in the transportation operation in the factory.

[0003] In the prior art, the method of air cooling the magnesia carbon bricks after they leave the kiln to speed up the cooling speed is a cooling method. However, since the blowing angle of the air cooling is fixed, there are dead corners for blowing, and the cooling efficiency of the magnesia carbon bricks is still not optimal, and there is still room for improvement.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a magnesium carbon brick cooling device with an adjustable air outlet angle to solve the shortcomings of the prior art. Utility Model Content

[0033] The utility model is further described in conjunction with the following embodiments.

[0034] Example 1.

[0035] like Figure 1-4As shown, a magnesium carbon brick cooling device with adjustable air outlet angle comprises a supporting platform 1 and two blowing hoods 2, the two blowing hoods 2 are symmetrically installed on both sides of either end of the supporting platform 1, a plurality of blowing rows 3 are opened on the blowing hood 2, each blowing row 3 comprises a plurality of air outlets 4, a blowing assembly 5 is installed at each air outlet 4, a driving mechanism 6 is fixedly installed on the supporting platform 1, L-shaped connecting rods 7 are symmetrically installed on both sides of the driving mechanism 6, a multi-connecting rod 8 is fixedly installed on one end of the two L-shaped connecting rods 7 away from the driving mechanism 6, and the multi-connecting rod 8 is connected to the blowing assembly 5.

[0036] The present application is used to perform air cooling on the magnesium carbon bricks after they leave the kiln, thereby achieving the beneficial effect of improving the efficiency of air cooling. First, two blowing hoods 2 are fixedly installed on both sides of either end of the supporting platform 1, and at the same time, an external blowing device is connected for blowing. A magnesium carbon brick frame with several rows of magnesium carbon bricks is placed between the two blowing hoods 2. Each blowing row 3 performs corresponding air cooling on each corresponding row of magnesium carbon bricks on the magnesium carbon brick frame. The driving mechanism 6 drives the L-shaped connecting rod 7 and the multi-connecting rod 8 to produce displacement, thereby driving the blowing assembly 5 to swing and adjusting the air outlet angle of the air outlet 4.

[0037] The blowing assembly 5 includes two air outlet baffles 51, which are rotatably installed on both sides of the air outlet 4 respectively. A movable ball groove 52 is opened on one side of the two air outlet baffles 51 close to the air outlet 4. A movable connecting piece 53 is rotatably installed inside the movable ball groove 52, and the bottom of the movable connecting piece 53 is fixedly connected to the multi-link 8.

[0038] The blowing assembly 5 adjusts the air outlet angle of the air outlet 4 through the synchronous rotation of the two air outlet baffles 51. The two air outlet baffles 51 achieve synchronous rotation through the rotation coordination of the movable connecting piece 53 and the movable ball groove 52. At the same time, the movable connecting piece 53 is connected through the bottom and the multi-link 8 to realize the displacement driven by the driving mechanism 6.

[0039] The multi-link 8 includes a connecting vertical rod 81, one side of which is fixedly connected to the driving mechanism 6, and the other side is equipped with a plurality of positioning cross rods 82. The number of the positioning cross rods 82 is the same as the number of the blowing rows 3. The positioning cross rods 82 are installed under the corresponding blowing rows 3, and the top of the positioning cross rod 82 is connected to the bottom of the movable connecting piece 53 of the corresponding blowing row 3.

[0040] The multi-link 8 is connected to the driving mechanism 6 by connecting the vertical rod 81 to realize the driving of the driving mechanism 6. At the same time, it drives the positioning cross rod 82 and the movable connecting member 53 to move and then drives the two air outlet baffles 51 to rotate synchronously, adjusts the air outlet angle, and performs air cooling on the magnesia carbon bricks at different angles.

[0041] The movable connecting member 53 includes a T-shaped column 531 , and ball heads 532 are fixedly installed at both horizontal ends of the T-shaped column 531 . The ball heads 532 are rotatably matched with the movable ball groove 52 , and the bottom of the T-shaped column 531 is fixedly connected to the corresponding positioning cross bar 82 .

[0042] The movable connecting piece 53 is rotatably installed in the movable ball groove 52 through the ball heads 532 at both ends of the T-shaped column 531. The opening diameter of the movable ball groove 52 at the bottom of the T-shaped column 531 is smaller than the diameter of the ball head 532 to prevent the ball head 532 from falling off. Then, the bottom of the T-shaped column 531 is connected to the positioning cross bar 82 to realize the multi-link 8 to drive the movable connecting piece 53 and then drive the angle of the blowing assembly 5 to rotate, adjust the blowing angle, and increase the cooling rate of the magnesium carbon brick. The T-shaped column 531 and the ball head 532 cooperate with the movable ball groove 52 to ensure that the two air outlets always rotate synchronously, and a certain opening is maintained to blow air to the magnesium carbon bricks for cooling.

[0043] Limit baffles 9 are installed on both sides of the blowing assembly 5 on the blowing cover 2.

[0044] The limiting baffle 9 can prevent the two air outlet baffles 51 from tilting at too large an angle, thereby affecting the air outlet volume.

[0045] The driving mechanism 6 includes a driving motor 61, which is fixedly mounted on the supporting platform 1. A ball screw 62 is fixedly mounted on the output end of the driving motor 61. A positioning end plate 63 is also fixedly mounted on the supporting platform 1. The end of the ball screw 62 away from the driving motor 61 is rotatably mounted on the positioning end plate 63. A nut 64 is spirally mounted on the ball screw 62, and L-shaped connecting rods 7 are fixedly mounted on both sides of the nut 64.

[0046] The driving mechanism 6 drives the ball screw 62 to rotate through the output of the driving motor 61, and then drives the nut 64 that is spirally matched with it to perform linear displacement. The nut 64 drives the L-shaped connecting rod 7 and the multi-link 8 to displace, thereby adjusting the blowing angle of the blowing assembly 5.

[0047] The utility model uses two blowing hoods 2 to air-cool the magnesia-carbon bricks on both sides of the magnesia-carbon brick frame after leaving the kiln, and at the same time realizes the periodic change of the blowing angle of the magnesia-carbon bricks through the cooperation of the driving mechanism 6 and the blowing component 5, thereby reducing the dead angle of the magnesia-carbon bricks air-cooling and improving the efficiency of the magnesia-carbon bricks air-cooling.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
