The sealing structure is used for being matched with the driving plates to keep the position of the sealing gasket on the driving plates to be limited when the gap between the driving plates changes. And the position of the sealing gasket can be limited through the embedding part, so that the falling phenomenon is avoided, and material leakage is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of grate cooler seals, and particularly relates to a drive plate seal structure for a cross bar grate cooler. Background Art

[0002] Since the fourth-generation cross bar grate cooler (FLSmisdth Cross-BarTM Cooler) launched by FLSmidth of Denmark in 2010, it has been promoted for its unique features such as separate clinker cooling and conveying systems; the grate bed is fixed and completely sealed between grate plates; the optimized clinker conveying method enables the realization of a horizontal grate bed; a mechanical automatic cooling air volume regulating valve; modular design and assembly, etc. Especially in recent years, many domestic cement enterprises have replaced the third-generation grate coolers, achieving remarkable results in improving thermal efficiency and reducing power consumption.

[0003] The reserved expansion joint size between the drive plates of the grate cooler is generally 5 mm. The existing sealing method is to pour silicone adhesive SI595 and fill nylon cord to form a tough, well-integrated and flexible rubber seal. However, due to the 200-mm-long vertical through-gap between the drive plates, it is difficult to fully fill and holes or voids are formed; and there is no fixed protection device on both sides of the through-gap, which is extremely easy to cause the seal to debond and fall off during the stroke movement of the drive plate. Summary of the Utility Model

[0004] Technical Objective: Aiming at the deficiency that the gap seal between the drive plates of the existing grate cooler is not good and prone to ash leakage, the utility model discloses a drive plate seal structure for a cross bar grate cooler that can ensure the sealing effect and avoid the seal from falling off.

[0005] Technical Solution: To achieve the above technical objective, the utility model adopts the following technical solution:

[0006] A drive plate seal structure for a cross bar grate cooler, including a gasket arranged between the mating gaps of two drive plates. The surface of the gasket is in clearance fit with the adjacent drive plate end face. The size of the gasket is consistent with the shape of the drive plate end face. A limiting structure is arranged at the upper end of the gasket to cooperate with the drive plate to limit the position of the gasket on the drive plate when the gap of the drive plate changes.

[0007] Preferably, the limiting structure of the utility model includes a fitting part extending towards the drive plate side along the direction perpendicular to the gasket. The fitting part and the gasket together form a T-shaped seal structure, and a keyway is arranged on the drive plate to cooperate with the fitting part.

[0008] Preferably, the width and depth of the keyway of the utility model are both 10 mm, and the length of the keyway matches the length of the fitting part.

[0009] Preferably, both the gasket and the fitting part of the present utility model are made of silicone rubber material.

[0010] Preferably, the gasket and the fitting part of the present utility model are integrally vulcanized and formed in a mold.

[0011] Preferably, the gap between the surface of the gasket of the present utility model and the end face of the adjacent drive plate is ≤ 0.5 mm.

[0012] Beneficial effects: The drive plate sealing structure for a cross-bar grate cooler provided by the present utility model can effectively seal between two drive plates of the grate cooler. At the same time, even if the gap between the drive plates changes, the position of the gasket can be restricted by the fitting part, avoiding the phenomenon of falling off, thereby avoiding material leakage.

[0019] Now, reference will be made in detail to the embodiments of the present disclosure, one or more examples of which are set forth below. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. On the contrary, the following description provides a convenient illustration for implementing the exemplary embodiments of the present disclosure. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the teachings of the present disclosure without departing from the scope or spirit of the present disclosure. For example, features shown or described as part of one embodiment can be combined with another embodiment to produce yet another embodiment. It is intended that the present disclosure cover such modifications and variations that fall within the scope of the appended claims and their equivalents. Other objects, features, and aspects of the present disclosure are disclosed or apparent from the following detailed description. It is to be understood by those of ordinary skill in the art that this discussion is only a description of exemplary embodiments and is not intended to limit the broader aspects of the present disclosure.

[0020] As shown Figures 1-4 in the figure, the utility model discloses a driving plate sealing structure for a cross bar grate cooler, which includes a sealing gasket 2 arranged between the mating gaps of two driving plates 1. The surface of the sealing gasket 2 is in clearance fit with the end face of the adjacent driving plate 1. The size of the sealing gasket 2 is consistent with the shape of the end face of the driving plate 1. A limiting structure is arranged at the upper end of the sealing gasket 2 for cooperating with the driving plate 1 to limit the position of the sealing gasket 2 on the driving plate 1 when the gap of the driving plate 1 changes.

[0021] The limiting structure of the utility model includes a fitting part 3 extending towards the side where the driving plate is located along the direction perpendicular to the sealing gasket 2. The fitting part 3 and the sealing gasket 2 together form a sealing structure with a T-shaped cross section. A keyway 4 is arranged on the driving plate 1 for cooperating with the fitting part 3.

[0022] Generally, the length * width * thickness dimensions of the driving plate of the grate cooler are 4000 * 200 * 20 mm, and the reserved gap is 5 mm. As shown Figure 3 in the figure, it is very difficult to completely fill the depth of 200 mm by perfusion. The sealing structure of the utility model is a modification on the original structure of the grate cooler, and is sealed by filling the sealing gasket. The gap between the two driving plates is 11 mm, the thickness of the sealing gasket 2 can be 10 mm, and the length of the sealing gasket is 200 mm, so that the gap between the surface of the sealing gasket 2 and the end face of the adjacent driving plate 1 is ≤ 0.5 mm, which not only ensures the sealing but also facilitates the assembly between the structures.

[0023] The width and depth of the keyway are both preferably 10 mm, and the length of the keyway matches the length of the fitting part 3. In the embodiment of the utility model, the embedding length is 35 mm to ensure that it can be embedded into the keyway to avoid crosstalk and falling off.

[0024] Both the sealing gasket 2 and the fitting part 3 of the utility model are made of silicone rubber material and are integrally vulcanized and formed in a mold. The temperature resistance is 170 - 200 degrees Celsius, and it has sufficient elasticity to fully meet the requirements of the deformation compensation amount caused by the thermal expansion and contraction of the driving plate. When the grate cooler is running, the gap between the driving plates is sealed through the sealing structure of the utility model.
