Description

Technical Field

[0001] The utility model relates to the technical field of grate plates, in particular to a grate plate structure of a grate type cooler. Background Art

[0002] Grate cooler is a quenching cooler. After the clinker enters the cooler from the kiln, it forms a material layer of a certain thickness on the grate plate. The cold air blown in passes through the material layer moving on the grate bed in a mutually perpendicular direction to quench the clinker. The clinker can be quenched from 1300-1400℃ to below 100℃ in a few minutes. Traditional grate coolers are divided into three types: rotary, vibrating and push-type. However, since the first two types have been eliminated, the push-type grate cooler has become the main cement clinker cooler model used in the off-kiln decomposition kiln. The grate bed is the main component of the cooler, and the push-type grate plate is composed of fixed grate plates and movable grate plates arranged in rows.

[0003] The existing grate plates still have some shortcomings. First of all, when most of the grate plates are connected to the grate cooler on both sides, they are mostly installed and connected with the grate cooler by cumbersome bolts. During installation, the grate plate is fixed to the frame of the grate cooler from both sides by bolts, and the installation process takes a long time. At the same time, the grate plate may become loose after working for a period of time in the bolt connection method, which makes the bolt connection not only inconvenient to install, but also consumes more operating time due to maintenance and reinstallation, reducing the normal working efficiency of the grate cooler.

[0004] Therefore, it is necessary to provide a grate plate structure of a grate type cooler to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide a grate plate structure of a grate type cooler, which has the advantages of simple installation and operation, and the grate plate body is not easy to loosen and fall off, thereby ensuring the normal operation of the grate type cooler.

[0006] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a grate plate structure of a grate type cooler, including a grate plate body, a placement groove is opened in the grate plate body, and a positive and negative threaded screw is rotatably installed in the placement groove, and the thread directions of the two ends of the positive and negative threaded screw are opposite, and main sliding grooves are opened on both sides of the grate plate body, and the two main sliding grooves are connected with the placement groove, and mounting plates are slidably connected in the two main sliding grooves, and bolts are threadedly connected on the two mounting plates, and the bolts are provided in plurality, and the two mounting plates are respectively threadedly connected to the two ends of the positive and negative threaded screw, and a rotating groove is opened on the grate plate body, and the rotating groove is connected with the placement groove, and a swivel is fixedly installed on the outside of the positive and negative threaded screw, and the swivel is located in the rotating groove, and a limiting mechanism is provided in the two main sliding grooves.

[0007] By adopting the above technical scheme, during the use of the grate cooler, the grate plate body is placed in the frame on the grate cooler, and the frame is used to wrap the grate plate body. After roughly adjusting the position, the positive and negative threaded screws are rotated through the swivel. When the positive and negative threaded screws are rotated, the mounting plates threaded at both ends will move outward, so that the two mounting plates are completely fitted with the inner wall of the frame. The limiting mechanism prevents the two mounting plates from being separated from the grate plate body. After the mounting plates on both sides of the grate plate body are fitted with the frame, multiple bolts are rotated to fix the mounting plates to the frame through the bolts. When the grate cooler is running, the positive and negative threaded screws squeeze the mounting plates at both ends into the frame and lock them to prevent the grate plate body from falling off. The grate plate body is then reinforced with bolts to fix the grate plate body on the grate cooler. The installation process is simple to operate, and the grate plate body is not easy to loosen or fall off, thereby ensuring the normal operation of the grate cooler.

[0008] The utility model is further configured as follows: the two mounting plates are respectively of "[" type and "]" type, and connecting blocks are fixedly installed on the relative inner sides of the two mounting plates, and the two connecting blocks are respectively adapted to the corresponding main slide grooves.

[0009] By adopting the above technical solution, the two mounting plates are slidably connected to the corresponding main sliding grooves through the connecting blocks respectively.

[0010] The utility model is further configured as follows: the limiting mechanism includes a limiting plate and a limiting groove, the limiting plates are fixedly installed on the relative inner sides of the two connecting blocks, the limiting grooves are provided on the relative outer sides of the two main slide grooves, the size of the limiting plate is the same as that of the main slide groove, and the size of the limiting groove is smaller than that of the main slide groove.

[0011] By adopting the above technical solution, since the size of the limit groove is smaller than that of the main slide groove, and the size of the limit plate is the same as that of the main slide groove, when the forward and reverse thread screws rotate, the connecting blocks and the mounting plates at both ends can slide in the main slide groove, but the limit plate cannot slide out of the limit groove, so that the connecting blocks and the mounting plates at both ends will not fall off the main slide groove.

[0012] The utility model is further configured as follows: a rotating handle is fixedly mounted on the outer side of the rotating ring, and a plurality of rotating handles are provided.

[0013] By adopting the above technical solution, during installation, it is more convenient for the operator to rotate the swivel through the rotating handle, and then rotate the forward and reverse thread screw.

[0014] The utility model is further configured as follows: both sides of the grate plate body are provided with secondary slide grooves, and two secondary slide grooves are provided on both sides of the grate plate body, and the plurality of secondary slide grooves are respectively matched with corresponding mounting plates.

[0015] By adopting the above technical solution, the protruding parts of the two mounting plates slide in the sliding grooves, further preventing the two connecting blocks and the mounting plates from being separated from the grate plate body.

[0016] The utility model is further configured as follows: a sealing door is arranged in the rotating groove, the sealing door is slidably connected to the grate plate body, and a protrusion is fixedly installed on the sealing door.

[0017] By adopting the above technical solution, during installation, after adjusting the position of the mounting plate by rotating the rotating ring and the forward and reverse threaded screws through the rotating handle, the sealing door is pushed through the protrusion to close the rotating groove to prevent the clinker on the grate plate body from clogging the rotating groove when the grate cooler is running.

[0018] In summary, the utility model has the following beneficial effects: the utility model rotates the swivel ring and the forward and reverse threaded screw by the turning handle. When the forward and reverse threaded screw rotates, the mounting plates with threads at both ends will move outward, thereby squeezing the mounting plates at both ends into the frame and locking them, and then rotating multiple bolts to fix the mounting plates to the frame through the bolts, and fixing the grate plate body on the grate cooler. The installation project is simple to operate, and the grate plate body is not easy to loosen and fall off, thereby ensuring the normal operation of the grate cooler.
