Description

Technical Field

[0001] This utility model relates to the field of grate cooler guard plate technology, specifically a guard plate structure for a grate cooler. Background Technology

[0002] The grate cooler is an important piece of mechanical equipment in the clinker calcination system of a cement plant. It is used to cool and transport cement clinker. The grate plate inside the grate cooler can exchange heat between hot air and cooling water through its surface, thereby cooling the cooling water and the equipment and machinery inside the grate cooler. To ensure the stability of the grate plate during use, a protective plate structure is usually installed on the grate plate to adjust the height of the grate plate and protect it.

[0003] A high-temperature resistant, detachable grate cooler guard plate, disclosed in CN216432536U, includes a base. Symmetrical through grooves are formed on the upper surface of the base, and an L-shaped guard plate is movably mounted on the upper surface of the base. Slide seats that are slidably connected to the through grooves are symmetrically mounted on the lower ends of the L-shaped guard plates. A fixed seat is mounted on one side of the L-shaped guard plate near its upper end, and a movable grate plate is movably mounted below the fixed seat. A sealing groove is formed on the upper surface of the movable grate plate, and a sealing gasket is installed inside the sealing groove. Springs are installed at equal intervals between the sealing gasket and the fixed seat. A support assembly is provided below the movable grate on one side of the base. A drive assembly for driving the slide is installed inside the base. The springs, sealing gaskets, and sealing grooves cause the movable grate to be subjected to downward pressure, thereby improving the connection stability between the movable grate and the support plate and improving the stability of the equipment after installation. The drive assembly drives the L-shaped guard plate to move, thereby adjusting the position of the L-shaped guard plate and improving the accuracy of equipment installation.

[0004] However, the above-mentioned grate cooler guard plate structure still has the following problems in use: The device uses an electric motor to adjust the height of the support plate, but the adjustment range is not large in actual use, and the adjustment interval is usually long, which increases the cost of use and damage. When fixing the grate plate, the upper end is squeezed and adhered. However, the length of the grate plate is long, so it is difficult to ensure that the grate plate is well pressed and fixed during the fixing process, and it is difficult to ensure the stability of the grate plate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a protective plate structure for a grate cooler. By rotating the handle, the height of the lower support plate can be adjusted, and then the grate can be stably pressed down by the support plate on the inclined structure.

[0006] This utility model provides the following technical solution: a grate cooler guard plate structure, including a grate guard plate, the lower end of which is slidably disposed on the upper end of a base, and an extension guard plate is fixedly installed on the right side of the base.

[0007] Furthermore, a movable sliding plate is fixedly installed at the lower end of the grate guard plate, and a sliding groove is provided on the base. The movable sliding plate is slidably connected to the base through the sliding groove on the base. A first bearing is installed on the base, and an adjusting screw is installed on the base through the first bearing. With the above structure, the movable sliding plate and the grate guard plate can be moved by rotating the adjusting screw.

[0008] Furthermore, a first threaded hole is provided at the middle position of the movable slide plate, and the adjusting screw is connected to the movable slide plate through the first threaded hole. A first positioning rod is provided through the left side of the adjusting screw, and the first positioning rod is engaged with the left side of the base. A first positioning spring is fixedly installed on the first positioning rod, and the first positioning spring is connected to the left side of the base. Through the above structure, the position of the adjusting screw can be fixed by the first positioning rod, so as to avoid the adjusting screw from rotating during subsequent use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a grate cooler guard plate structure, including a grate guard plate 1, the lower end of which is slidably disposed on the upper end of a base, and an extension guard plate 6 is fixedly installed on the right side of the base. A movable slide plate 2 is fixedly installed on the lower end of the grate guard plate 1, and a sliding groove is provided on the base. The movable slide plate 2 is slidably connected to the base through the sliding groove. A first bearing is installed on the base, and an adjusting screw 3 is installed on the base through the first bearing. A first threaded hole is provided at the middle position of the movable slide plate 2, and the adjusting screw 3 is connected to the movable slide plate 2 through the first threaded hole. A first positioning rod 4 is provided through the left side of the adjusting screw 3, and the first positioning rod 4 is engaged with the left side of the base. A first positioning spring 5 is fixedly installed on the first positioning rod 4, and the first positioning spring 5 is connected to the left side of the base.

[0021] The left side of the grate plate is in contact with the grate plate guard plate 1, and the right side of the grate plate is in contact with the base. As the grate plate deforms or wears down with use, its length may shorten. In this case, pulling the first positioning rod 4 will cause it to move away from the adjusting screw 3. Because a first positioning spring 5 is fixedly installed on the first positioning rod 4, the spring 5 will be stretched and deformed until the first positioning rod 4 is no longer engaged with the base. At this point, the adjusting screw 3 can be rotated, as it moves through the openings on the sliding plate 2. The first threaded hole is connected to the movable slide plate 2. At this time, the movable slide plate 2 begins to move towards the grate. Because the grate guard plate 1 is fixedly installed on the upper end of the movable slide plate 2, the grate guard plate 1 begins to move towards the grate until it is tightly fitted with the left side of the grate. After adjusting to the appropriate position, the first positioning rod 4 is released. Under the action of the first positioning spring 5 restoring its deformation, the first positioning rod 4 begins to be pulled towards the base until it is engaged with the base again. At this time, the stability of the grate guard plate 1 can be guaranteed.

[0022] A rotating handle 7 is rotatably mounted at the middle position of the extension guard plate 6, and a drive gear 10 is fixedly mounted at the lower end of the rotating handle 7. A fixing plate 15 is fixedly mounted on the right side of the grate guard plate 1, and a second threaded hole is opened in the middle position of the fixing plate 15. A rotating screw 16 is installed in the second threaded hole on the fixing plate 15. An adjusting plate 17 is slidably mounted on the right side of the grate guard plate 1. A second bearing is installed in the middle position of the adjusting plate 17, and the adjusting plate 17 is rotatably connected to the rotating screw 16 through the second bearing. A guide rod 19 is fixedly mounted on the upper end of the adjusting plate 17, and the guide rod 19 is slidably connected to the fixing plate 15. An upper support plate 18 is fixedly mounted on the lower end of the adjusting plate 17, and the upper support plate 18 is slidably mounted on the lower end of the adjusting plate 17. The lower end of the support plate 18 is in contact with the upper surface of the grate plate. A second positioning rod 8 is provided through the rotating handle 7, and the second positioning rod 8 is engaged with the extension guard plate 6. A second positioning spring 9 is fixedly installed at the lower end of the second positioning rod 8, and the second positioning spring 9 is connected to the upper surface of the rotating handle 7. Two driven gears 11 are meshed on the side of the driving gear 10, and a rotating screw 12 is fixedly installed at the upper end of the driven gear 11. The rotating screw 12 is rotatably connected to the extension guard plate 6. A fixing sleeve 13 is threadedly connected to the upper end of the rotating screw 12, and a lower support plate 14 is fixedly installed at the upper end of the fixing sleeve 13. The upper surface of the lower support plate 14 is in contact with the lower end of the grate plate.

[0023] When the height of the grate needs to be adjusted (in the clinker cooling process, adjusting the installation height of the grate can affect the cooling effect and heat recovery efficiency of the clinker; when the position of the grate needs to be adjusted upwards), rotate the rotating screw 16. Because the rotating screw 16 and the adjusting plate 17 form a rotating connection, and the rotating screw 16 is connected to the fixing plate 15 through the second threaded hole on the fixing plate 15, the adjusting plate 17 begins to move upwards under the action of the guide rod 19. Because the upper support plate 18 is fixedly installed at the lower end of the adjusting plate 17, the upper support plate 18 also begins to move upwards, that is, the upper support plate 18 begins to move away from the grate. Then pull the second positioning rod 8, and the second positioning rod 8 begins to move away from the rotating handle 7 until the second positioning rod 8 is no longer engaged with the extension guard plate 6, because the lower end of the second positioning rod 8 is installed with... The second positioning spring 9 is stretched and deformed. Then, the rotating handle 7 is rotated. Since the lower end of the rotating handle 7 is fixedly installed with the driving gear 10, the driving gear 10 starts to rotate. Since the driving gear 10 and the driven gear 11 mesh with each other, the driven gear 11 starts to rotate. Since the upper end of the driven gear 11 is fixedly installed with the rotating screw 12, the rotating screw 12 starts to move upward. Since the rotating screw 12 is threadedly connected with the fixed sleeve 13, the fixed sleeve 13 starts to move upward. Since the upper end of the fixed sleeve 13 is installed with the lower support plate 14, the lower support plate 14 starts to move upward until the lower support plate 14 is in contact with the lower end of the grate, thereby pushing the grate upward until the upper end of the grate is in close contact with the lower end of the upper support plate 18, thereby realizing the adjustment of the grate's working height.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
