[0001] The utility model relates to the technical field of grate coolers, in particular to a leakage-proof sealing device for the air chamber of a grate cooler. Background Technique

[0002] A grate cooler is a device used to cool powdery or granular materials. It mainly consists of an inclined grate plate and an air chamber. The material enters from the top of the grate plate and, under the action of gravity and vibration, flows downward along the grate plate and contacts the cold air blown out from the air chamber, thereby realizing the cooling of the material. The air chamber of the grate cooler is an important part of the grate cooler. It is located below the grate plate and is used to provide cold air to cool the material. The air chamber is usually designed as a closed box body, and a fan and an air duct system can be installed to send cold air under the grate plate and form a flowing air layer under the grate plate to fully contact the material to achieve cooling.

[0003] In the prior art, when cooling air is provided for the material through the air chamber, the air chambers are generally separated by partition plates. However, due to the displacement of the cross beam of the air chamber during movement, the sealing structure between the cross beam and the partition plate is prone to wear or loss during long-term use, which will affect the sealing performance and easily cause air leakage. Therefore, in order to solve the above problems, a leakage-proof sealing device for the air chamber of a grate cooler is proposed. Content of the Utility Model

[0022] Please refer to Figures 1-5 One embodiment provided by the present utility model:

[0023] A leakage prevention and sealing device for the air chamber of a grate cooler, including a plate body. The plate body includes a cross beam 1, and a partition board 11 is arranged on the surface of the cross beam 1. Through the arrangement of the partition board 11, the air chamber of the grate cooler can be partitioned, facilitating the uniform and efficient passage of cold air through the clinker layer to achieve the best cooling effect;

[0024] A sealing mechanism is arranged on the surface of the partition board 11. The sealing mechanism includes a sealing plate 2. The sealing plate 2 is arranged on the surface of the partition board 11. A sealing block 21 is fixedly connected to the inner surface of the sealing plate 2. A sealing groove 22 is opened on the inner side of the sealing block 21. A fixing rod 23 is fixedly connected to the inner wall of the sealing groove 22. A first spring 24 is fixedly connected to the inner wall of the fixing rod 23. A telescopic rod 25 is fixedly connected to the surface of the first spring 24. An extrusion block 26 is fixedly connected to the surface of the telescopic rod 25. A gasket 27 is fixedly connected to the surface of the sealing plate 2. Through the arrangement of the gasket 27, the connection between the cross beam 1 and the partition board 11 can be sealed, thereby avoiding air leakage between the cross beam 1 and the partition board 11 and also avoiding the situation of material leakage.

[0025] Further, one end of the first spring 24 is fixedly connected to the fixed rod 23, and the other end of the first spring 24 is fixedly connected to the telescopic rod 25. By providing the first spring 24, a certain force can be applied to the telescopic rod 25, so that the extrusion block 26 can press against the inner wall of the sealing groove 22 under the action of the telescopic rod 25, facilitating the tight fit between the sealing block 21 and the surface of the cross beam 1, and better avoiding the occurrence of air leakage.

[0026] Further, the telescopic rod 25 is movably disposed inside the fixed rod 23, and the extrusion block 26 is fixedly connected to the end of the telescopic rod 25 away from the first spring 24. By providing the extrusion block 26, the inner wall of the sealing groove 22 can be extruded, so that the sealing block 21 can better contact the surface of the cross beam 1, thereby improving the sealing performance between the partition plate 11 and the cross beam 1.

[0027] Further, a replacement mechanism is provided on the surface of the sealing plate 2. The replacement mechanism includes a fixed block 3 fixedly connected to the surface of the sealing plate 2. An installation groove 31 is formed inside the partition plate 11, and a movable groove 32 is formed inside the fixed block 3. The movable groove 32 is formed inside the fixed block 3 and the sealing plate 2. A movable rod 33 is movably connected inside the movable groove 32. A plug 34 is fixedly connected to the surface of the movable rod 33. A slot 35 is formed in the inner wall of the installation groove 31. A second spring 36 is fixedly connected to the surface of the movable rod 33. By the movement of the movable rod 33 inside the movable groove 32, the plug 34 can be moved accordingly to engage and disengage with the slot 35, facilitating the replacement of the sealing plate 2 and ensuring the sealing effect of the sealing plate 2 on the partition plate 11.

[0028] Further, the fixed block 3 is fixedly connected to the sealing plate 2 in four groups, the installation groove 31 is formed in the partition plate 11 in four groups, and the plug 34 is movably disposed inside the movable groove 32. By providing the fixed block 3 and the installation groove 31, the installation of the sealing plate 2 on the partition plate 11 can be positioned, preventing misalignment during the installation of the sealing plate 2 and ensuring the installation effect of the sealing plate 2.

The sealing block 21 can also seal between the cross beam 1 and the partition 11, achieving double sealing. The first spring 24 enables the telescopic rod 25 to move inside the fixed rod 23 and apply a certain force to the extrusion block 26. Then, the extrusion block 26 presses against the inner wall of the sealing groove 22, so that the sealing block 21 can be closely attached to the surface of the cross beam 1. Even when the sealing block 21 is worn or damaged to a certain extent, the sealing performance can still be guaranteed.

[0031] By pulling the movable rod 33, the movable rod 33 will move inside the movable groove 32. Then, the insertion block 34 will be separated from the insertion slot 35 under the action of the movable rod 33. At this time, the second spring 36 is in a contracted state, and the locking of the fixed block 3 can be released. Then, the fixed block 3 can be pulled out from the installation groove 31 to replace the sealing plate 2. When installing the replaced sealing plate 2, insert the fixed block 3 into the installation groove 31 and then release the movable rod 33. The movable rod 33 can be reset under the rebounding action of the second spring 36, driving the insertion block 34 to reset and engage with the insertion slot 35, thus fixing the sealing plate 2 and completing the installation.
