Its main functions include rapid cooling and conveying of cement clinker, while providing hot air for the rotary kiln and decomposition furnace. The grate cooler cools the clinker from 1300-1400℃ to below 100℃ within minutes by spreading the clinker into a layer of a certain thickness and blowing in cold air. The existing grate cooler has a relatively complex grate plate installation method, making it difficult to quickly disassemble and assemble the grate plates, which brings inconvenience to the cleaning or replacement of the grate plates and affects the convenience of later maintenance of the grate cooler. Based on this, this utility model designs a fixed grate plate for a grate cooler to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide a fixed grate plate for a grate cooler to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A fixed grate for a grate cooler includes a frame, a grate, a pressure seat, and a U-shaped seat. Support seats are provided on both sides of the frame. Two side ears are symmetrically arranged on both sides of the grate. A first upright is fixedly connected to the upper end of each support seat, and a second upright is fixedly connected to the bottom end of each pressure seat. The opposite end faces of the first and second uprights are in contact. The side ears are slidably fitted onto the first and second uprights. An elastic component I is provided between the support seat and the side ears, and an elastic component II is provided between the pressure seat and the side ears. A lower groove adapted to the bottom side of the U-shaped seat is provided on the side of the support seat, and an upper groove adapted to the top side of the U-shaped seat is provided on the side of the pressure seat. A locking component is provided between the pressure seat and the U-shaped seat.

[0006] As a preferred embodiment of this utility model, the elastic component I includes a lower spring and a retaining ring I. The lower spring is fixedly connected between the support base and the retaining ring I, and the side ear is in contact with the opposite end face of the retaining ring I.

[0007] As a preferred embodiment of this utility model, the elastic component II includes an upper spring and a retaining ring II. The upper spring is fixedly connected between the pressure seat and the retaining ring II, and the side ear is in contact with the opposite end face of the retaining ring II.

[0008] As a preferred embodiment of this utility model, the retaining ring I is slidably sleeved on the outside of the first upright, and the retaining ring II is slidably sleeved on the outside of the second upright.

[0009] As a preferred embodiment of this utility model, the locking assembly includes a locking stud and a knob block, the U-shaped seat and the pressure seat are both threadedly connected to the locking stud, and the knob block is fixedly connected to the end of the locking stud.

[0010] As a preferred embodiment of this invention, the cross-sectional shape of the knob block is a regular hexagon.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model allows for easy removal of the grate plate from the pressure seat by loosening the locking assembly and pulling out the U-shaped seat. After cleaning or replacing the grate plate, when it needs to be installed, the side ear is slidably fitted onto the outside of the first upright. The elastic component I supports the side ear, the second upright is inserted into the side ear, and the opposite end faces of the first and second uprights are in contact. The elastic component II presses against the side ear, and the bottom side of the U-shaped seat is inserted into the lower groove on the side of the support seat, while the top side of the U-shaped seat is inserted into the upper groove on the side of the pressure seat. The locking assembly is then used to lock and fix the U-shaped seat and the pressure seat. This simplifies the installation of the grate plate in the grate cooler, facilitates quick disassembly and assembly of the grate plate, makes cleaning or replacing the grate plate more convenient, and improves the ease of maintenance of the grate cooler.

[0013] 2. This utility model, by setting up elastic component I and elastic component II, allows cement clinker to fall onto each grate plate. The force causes the side ears of the grate plate to drive the retaining ring I to descend, compressing the lower spring. After absorbing and buffering the force, the elastic force of the lower spring pushes the retaining ring I to move the grate plate upward. The retaining ring II then compresses the upper spring. Thus, the elastic components I and II can achieve a good buffering effect, thereby effectively protecting the grate plate. Attached Figure Description
