Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a sealing device for a transmission mechanism of a grate cooler used in cement production. Background Art

[0002] Cement production is a well-known industry. During the cement production process, the grate cooler is an important main equipment in the cement clinker burning system. Its main function is to cool and transport the cement clinker. At the same time, it provides hot air to the rotary kiln and decomposition furnace, and is the main equipment for heat recovery in the burning system. However, during the use of the grate cooler, its transmission mechanism is prone to dust leakage and other harmful phenomena. Therefore, the sealing of the transmission mechanism is also a problem that people are very concerned about.

[0026] A sealing device for a grate cooler transmission mechanism for cement production comprises: an equipment housing 1, a sealing chamber 11 mounted on the left side wall of the equipment housing 1, a transmission shaft 12 movably mounted on the inner side of the sealing chamber 11 via a bearing, and a cleaning brush 13 fixedly mounted in the middle of the transmission shaft 12;

[0027] A sealing structure 2 is installed on the equipment housing 1, and the sealing structure 2 includes a conical outer cover 21, which is fixedly installed on the right side wall of the equipment housing 1. A drainage groove 22 is provided at the left end of the bottom surface of the conical outer cover 21, and a conical inner cover 23 is fixedly connected to the inner side of the right end of the conical outer cover 21. A sealing brush 24 is fixedly installed on the inner left end of the conical inner cover 23. Through the cooperation of the conical outer cover 21 and the conical inner cover 23, the cover can be arranged on the outside of the connection between the equipment housing 1 and the drive shaft 12, and the conical outer cover 21 and the conical inner cover 23 are arranged in a ">" shape, which can guide dust to drift between the conical outer cover 21 and the conical inner cover 23 away from the gap between the conical inner cover 23 and the drive shaft 12, and cooperate with the sealing brush 24 to further prevent dust from escaping from the gap between the conical inner cover 23 and the drive shaft 12, thereby improving the sealing effect of the device.

[0028] Furthermore, a collecting structure 3 is installed on the sealed chamber 11, and the collecting structure 3 includes a collecting box 31, which is movably installed on the bottom surface of the sealed chamber 11, and a guide block 32 is fixedly connected to the top surface of the collecting box 31. A card slot 33 is opened on the inner wall of the collecting box 31, and a pull rod 34 is inserted into the inner side of the card slot 33. The surface of the pull rod 34 is sequentially installed with an upper arc plate 35 and a lower arc plate 36 from top to bottom. A movable plate 37 is installed at the bottom end of the inner side of the collecting box 31, and a handle 38 is fixedly connected to the bottom surface of the movable plate 37. The powder falls downward and can be The powder enters the collection box 31 at the connection point and is collected on the top surface of the movable plate 37. The gap between the upper arc plate 35 and the lower arc plate 36 is vertical, which can prevent the powder from flying out. By pulling the collection box 31, the guide block 32 slides on the sealed chamber 11, and the collection box 31 can be separated from the sealed chamber 11. The pull rod 34 is pulled, and the pull rod 34 can slide in the slot 33 to lift the upper arc plate 35 and the lower arc plate 36 from the collection box 31. Push the handle 38 upward to lift the movable plate 37 from the collection box 31, and the powder on the movable plate 37 can be ejected, which is convenient for processing the powder.

[0029] Furthermore, the transmission shaft 12 passes through the sealed chamber 11 and the device housing 1 , and the cleaning brush 13 is in contact with the inner wall of the sealed chamber 11 . The rotation of the transmission shaft 12 can drive the cleaning brush 13 to scrape the powder on the inner wall of the sealed chamber 11 .

[0030] Furthermore, the conical outer cover 21 and the conical inner cover 23 are both conical, and the cross-section of the connection between the conical outer cover 21 and the conical inner cover 23 is ">"-shaped. When the dust moves to the connection between the conical outer cover 21 and the conical inner cover 23, the dust can be guided to drift away from the gap between the conical inner cover 23 and the drive shaft 12, thereby reducing the emission of dust.

[0031] Furthermore, the inner wall of the sealing brush 24 is in contact with the outer wall of the transmission shaft 12 , and the sealing brush 24 can prevent powder from escaping from the gap between the conical inner cover 23 and the transmission shaft 12 .

When the dust moves to the connection between the conical outer cover 21 and the conical inner cover 23, the dust can be guided to drift away from the gap between the conical inner cover 23 and the transmission shaft 12, and the inner wall of the sealing brush 24 fits the outer wall of the transmission shaft 12, which can further prevent the dust from escaping from the gap between the conical inner cover 23 and the transmission shaft 12, thereby improving the sealing effect of the device.

[0034] When the cleaning brush 13 rotates inside the sealed chamber 11, it can brush off the powder on the inner wall of the sealed chamber 11. The powder falls downward and enters the collection box 31 through the connection between the upper arc plate 35 and the lower arc plate 36, and is collected on the top surface of the movable plate 37. The gap between the upper arc plate 35 and the lower arc plate 36 is vertical, which can prevent the powder from flying out.
