Description

Technical Field

[0001] The present invention relates to the technical field of kiln equipment, and in particular to a kiln sealing device. Background Art

[0002] In the prior art, ordinary tunnel kiln sand sealing troughs and kiln car sand sealing skirts are usually used to seal the kiln. The use of ordinary tunnel kiln sand sealing troughs and kiln car sand sealing skirts for sealing has the following disadvantages: (1) Ordinary tunnel kiln sand sealing troughs need to be filled with sand for sealing, and the kiln car sand sealing skirts extend into the sand. During the movement of the kiln car, the sand sealing skirts drive the sand to flow. The filling degree of sand in the sand sealing trough is not enough to completely isolate the air, allowing the wrong air to enter the kiln; (2) After running for a long time, the kiln car sand sealing skirts will deform and expand to varying degrees, causing the kiln car to wear, resulting in poor sealing, air leakage, and further causing the bottom temperature of the car to be too high, burning the kiln car bearings, and causing The thermal system in the kiln is abnormal, the temperature is uneven, and the brick baking temperature cannot be reached. The quality of the fired products is poor, or even the products cannot be fired. (3) In production, there is a common phenomenon that the kiln car scrapes the kiln wall (the kiln wall below the main car surface height) and the sand sealing groove of the tunnel kiln, causing the kiln car to be stuck in the kiln and unable to move forward or backward. The staff can only "risk" the fire to remove the car until they have to shut down the kiln, causing operational difficulties, increased heat consumption, increased load on the smoke exhaust equipment, increased damage in the kiln, waste of resources, unsafe kiln body, and increased operating costs and maintenance costs.

The spring 16 is sleeved on the first pipe fitting 14 and the second pipe fitting 15, and one end of the spring 16 abuts against the movable part 8 and the other end abuts against the fixed part 11; one end of the sealing plate 7 is fixedly connected to the side of the movable part 8 away from the fixed part 11; the fixed part 11, the movable part 8 and the sealing plate 7 are all arranged horizontally.

[0032] In this embodiment, the fixed member 11 is made of channel steel, the movable member 8 is made of C-shaped steel, and the sealing plate 7 is made of high-temperature resistant fiberboard. One end of the movable member 8 is inserted into the groove of the movable member 8. A rib plate 19 is fixed to each end of the fixed member 11. The rib plate 19 is connected to a connecting plate 20 via screws 21. The connecting plate 20 is welded to the column of the kiln wall 2. The diameter of the first pipe 14 is smaller than that of the second pipe 15. The other end of the first pipe 14 can be inserted into the second pipe 15. The first pipe 14 and the second pipe 15 are coaxial, and there is a gap between the side wall of the first pipe 14 and the side wall of the second pipe 15.

[0033] A slide groove is also provided on the kiln wall 2, and the moving part 8 slides with the slide groove, and the other end of the sealing plate 7 can extend out of the slide groove; a bent steel plate 9 and a special-shaped curved sealing steel plate 10 are provided on the kiln wall 2, and the bent steel plate 9 is L-shaped. The bent steel plate 9 includes a first horizontal plate and a first vertical plate. The bent steel plate 9 is located below the special-shaped curved sealing steel plate 10, and the bottom end of the special-shaped curved sealing steel plate 10 has a second horizontal plate. The first horizontal plate and the second horizontal plate form a slide groove.

[0034] The fixed member 11 is provided with a drive device and a transmission unit. The drive device can drive the movable member 8 toward the fixed member 11 through the transmission unit. Specifically, the transmission unit includes a main connecting rope 17 and a sub-transmission unit corresponding to each telescopic structure. The sub-transmission unit includes a sub-connecting rope 18 and a fixed pulley 22 provided on the fixed member 11. The fixed member 11 is provided with a through hole corresponding to each sub-connecting rope 18. The sub-connecting rope 18 passes through the first pipe 14, the second pipe 15, and the through hole to be fixedly connected to the main connecting rope 17. The sub-connecting rope 18 is wound around the fixed pulley 22 in the same transmission unit. The drive device is a cylinder 12. The piston rod of the cylinder 12 is provided with a fork joint. One end of the main connecting rope 17 is fixedly connected to the fork joint. In this embodiment, both the main connecting rope 17 and the sub-connecting rope 18 are made of fine steel wire rope.

[0035] The kiln wall 2 is also provided with a window, located on the side of the kiln wall 2 away from the sealing plate 7.

The specific operating process of the kiln sealing device of this embodiment is as follows: When the kiln car 6 needs to enter, the kiln door 1 is raised to a certain height. The limit switch transmits a signal to the cylinder 12, which drives the main connecting rope 17 and the sub-connecting rope 18, allowing the sealing plate 7 to separate from the kiln car side panels 5. Then, the kiln car 6 can be driven into the kiln. When the kiln car 6 reaches the set position, the kiln door 1 immediately drops. The limit switch transmits a signal to the cylinder 12, which loosens the main connecting rope 17 and the sub-connecting rope 18. The spring 16 is released, allowing the sealing plate 7 to be tightly attached to the kiln car side panels 5, preventing indoor air from passing through, and ensuring a tight seal without air leakage.
