Abstract
Description
Technical Field
[0001] This utility model relates to a cement raw material feeding device, and more particularly to the structure of the cement raw material feeding device. Background Technology
[0002] Cement is a powdered hydraulic inorganic binder that forms a paste when mixed with water. It hardens in air or water and can firmly bind materials such as sand and stone together. As an important binder, cement is widely used in civil engineering, water conservancy, and national defense projects. Cement is made by firing cement raw materials, which are materials composed of calcareous raw materials, clay raw materials, and a small amount of corrective materials (sometimes with the addition of mineralizers, seed crystals, etc.) in a specific ratio.
[0003] In cement production, conveyor belts are used to transport cement raw materials to the rotary kiln. The existing method usually involves directly feeding the cement raw materials discharged from the cement raw material mixing and crushing equipment onto the conveyor belt. Since there is a certain height difference between the cement raw material mixing and crushing equipment and the conveyor belt, the cement raw materials falling onto the conveyor belt at high speed will impact the conveyor belt, causing damage to the conveyor belt and generating a large amount of dust, which pollutes the environment.
[0004] The purpose of this invention is to solve the problem of damage to the conveyor belt and dust generation when cement raw materials are fed onto the conveyor belt. Summary of the Invention
[0005] To address the aforementioned problems, this utility model provides a cement raw material feeding device, comprising a box body 1 and a buffer device 2. The box body 1 has an inlet 11 at its upper part and an outlet 12 at its bottom, forming a buffer cavity 13 inside. The buffer device 2 is disposed within the buffer cavity 13 and includes multiple buffer members 3 staggered on opposite side walls of the box body 1. Each buffer member 3 includes a support plate 31, a buffer plate 32, and multiple buffer springs 33. One end of the support plate 31 is fixedly connected to the inner wall of the box body 1, and the other end extends inclined downwards towards the center of the box body 1. The buffer springs 33 are vertically disposed on the support plate 31, with their lower ends fixedly connected to the top surface of the support plate 31. The multiple buffer springs 33 are evenly distributed on the support plate 31. The buffer plate 32 is located above the support plate 31, and the bottom surface of the buffer plate 32 is fixedly connected to the upper ends of each buffer spring 33.
[0006] When using this utility model, the device is installed between the cement raw material mixing and crushing equipment and the conveyor belt, so that the feed inlet 11 of the box body 1 is located below the discharge port of the cement raw material mixing and crushing equipment, and the discharge port 12 of the box body 1 is located above the conveyor belt. After the cement raw material comes out of the discharge port of the cement raw material mixing and crushing equipment, it enters the box body 1 through the feed inlet 11, is buffered by the buffer components 3 of the buffer device 2, and is discharged from the discharge port 12, slowly falling onto the conveyor belt.
[0007] This invention utilizes multiple staggered buffer elements 3 to ensure that the cement raw material falls slowly along a zigzag path within the housing 1. This reduces the falling speed of the cement raw material, preventing it from impacting the conveyor belt and causing damage, and also reduces dust generation. Buffer springs 33 cushion the buffer plate 32, reducing the impact of cement material on it and preventing damage, further minimizing dust generation. This invention effectively solves the problem of conveyor belt damage and dust generation when cement raw material is fed onto the conveyor belt.

[0009] By setting a sliding rod 34 and a sliding groove 311 on the support plate 31, the lower end of the sliding rod 34 is inserted into the sliding groove 311. The sliding rod 34 can limit the buffer plate 32 and prevent the buffer plate 32 from sliding diagonally downward along the support plate 31.

[0029] The buffer device 2 is installed in the buffer cavity 13 and includes multiple buffer components 3. The multiple buffer components 3 are arranged in two groups opposite to each other in the buffer cavity 13.
