Description

Technical Field

[0001] This utility model relates to the technical field of grate cooler guard plates, specifically a split-type grate cooler guard plate. Background Technology

[0002] The grate cooler guard plate is an important component of the grate cooler in a cement plant. It is mainly used to protect the key parts of the grate cooler and prevent wear and damage. The grate cooler is an important piece of equipment in the clinker calcination system of a cement plant. Its main function is to cool and transport cement clinker, while providing hot air for rotary kilns and decomposition furnaces. It is the main equipment for heat recovery in the calcination system.

[0003] Chinese Patent Publication No. CN218210814U discloses a detachable grate cooler side guard plate, including a base plate. A replacement plate is movably mounted on the top of the base plate. Two symmetrical sliding grooves are formed at the upper end of the base plate, and sliders are slidably mounted in the sliding grooves. The upper end of each slider has a groove. The bottom of the replacement plate has symmetrical through grooves corresponding to the grooves. A positioning block is slidably mounted inside each through groove. A pull rod is fixedly mounted at the upper end of each positioning block, and the pull rod extends through the through groove to the top of the replacement plate. This detachable grate cooler side guard plate, by forming grooves in the sliding grooves and setting positioning blocks on the replacement plate, allows for easy replacement of the plate. When a new replacement plate needs to be replaced, the new plate is placed on it, and the positioning block is slid into the groove. When the positioning block slides to abut against the side wall of the groove near the assembly hole, the assembly hole on the replacement plate can be aligned with the assembly hole on the slider in the base plate, reducing the time spent by workers on the holes and making it more convenient to use.

[0004] In existing split-type grate coolers, a certain gap is left between the guard plate and the movable grate to avoid friction. During use, clinker can fall into this gap and get stuck. When the movable grate moves, it still causes wear between the guard plate and the movable grate. Therefore, we propose a split-type grate cooler guard plate. Summary of the Invention

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See also Figure 1-4A split-type grate cooler guard plate includes an upper guard plate 1, with a first mounting cavity 3 inside the upper guard plate 1. A first mounting protrusion 4 is integrally fixedly installed below the rear end of the upper guard plate 1. A lower guard plate 7 is installed below the upper guard plate 1, with a second mounting cavity 8 inside the lower guard plate 7. A conveyor roller 9 is installed inside the second mounting cavity 8, with mounting bearings 12 installed at both ends of the conveyor roller 9. A transmission belt 2 is installed on the outer surface of the conveyor roller 9. The transmission belt 2 is made of aluminum silicate ceramic fiber felt material. The inner wall of the second mounting cavity 8 has a groove... The bearing 12 is installed in a bearing mounting groove 13 corresponding to its bearing 12; the shape and size of the bearing 12 match the shape and size of the bearing mounting groove 13, and the conveyor roller 9 is detachably connected to the second mounting cavity 8 through the bearing 12 and the bearing mounting groove 13, and is also detachably connected to the first mounting cavity 3; the conveyor roller 9 rotates inside the second mounting cavity 8 through the bearing 12 and the bearing mounting groove 13, and the transmission belt 2 is driven inside the second mounting cavity 8 through the conveyor roller 9; the transmission belt 2 rotates inside the second mounting cavity 8 through the inner part of the split grate cooler guard plate. A transmission belt 2 is installed in the lower guard plate 7. When the movable grate plate reciprocates, the friction between the movable grate plate and the grate cooler guard plate drives the transmission belt 2, thus preventing friction damage caused by relative movement between them and extending their service life. A second mounting protrusion 5 is integrally fixedly installed above the rear end of the lower guard plate 7, and a third mounting protrusion 6 is integrally fixedly installed below the rear end of the lower guard plate 7. A first mounting bolt 10 passes through the first mounting protrusion 4. Inside, the first mounting bolt 10 passes through the interior of the first mounting protrusion 4 and the second mounting protrusion 5 in sequence. The first mounting protrusion 4 is bolted to the second mounting protrusion 5 through the first mounting bolt 10. The upper guard plate 1 is detachably connected to the lower guard plate 7 through the first mounting protrusion 4, the second mounting protrusion 5 and the first mounting bolt 10. The detachable upper guard plate 1 and lower guard plate 7 make it easy to disassemble the upper guard plate 1 and the lower guard plate 7 to replace the damaged transmission belt 2. The second mounting bolt 11 passes through the interior of the third mounting protrusion 6.

[0024] Working principle: When using this split-type grate cooler guard plate, firstly, the lower guard plate 7 is installed on the grate cooler using the second mounting bolt 11 on the third mounting protrusion 6. Then, during use, the movable grate plate will reciprocate. The movable grate plate will drive the transmission belt 2 through the conveyor roller 9 to achieve back-and-forth transmission inside the first mounting cavity 3 and the second mounting cavity 8 through friction. This effectively pushes the material and avoids friction between the movable grate plate and the transmission belt 2. Secondly, the transmission belt 2 is made of aluminum silicate ceramic fiber felt material, which has excellent high temperature resistance and ensures the normal temperature inside the grate cooler. Thirdly, when the transmission belt 2 is damaged and needs to be replaced, the first mounting bolt 10 on the first mounting protrusion 4 and the second mounting protrusion 5 is unscrewed, and the upper guard plate 1 is removed from the lower guard plate 7. The transmission belt 2 can then be disassembled and replaced. The installation method between the conveyor roller 9 and the first mounting cavity 3 is the same as the installation method between the conveyor roller 9 and the second mounting cavity 8. This is the working principle of this split-type grate cooler guard plate.

[0025] 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.
