Abstract

[0002] Molded bricks generally refer to small man-made blocks used in construction, which are divided into sintered bricks and unsintered bricks, commonly known as bricks. Sintered bricks refer to bricks made of clay or fly ash as raw materials, which are formed by high-temperature baking after adding a certain amount of additives. When sintered bricks are produced, they need to go through the following processes in sequence: soil collection, filtering and screening, mud making, blank making and drying and baking. Filtration and screening is to screen the raw material particles of different sizes.
[0003] A sintered brick raw material screening device with publication number CN214347868U is mainly composed of a screening box and a filter screen inside the screening box. When screening the raw soil, the raw soil is poured onto the filter screen in the screening box, and then the raw soil is filtered through the filter screen by vibrating the filter screen. Large particles of solid impurities in the raw soil remain on the filter screen, and the raw soil falls to the bottom of the screening box. During use, the large-particle material after screening sinks to the bottom and accumulates, which will affect the passage of subsequent small-particle materials. Utility Model Content

[0020] The material discharge port 5 is located below the rolling screen 2, and the debris discharge port 6 is located below the opening of one end of the rolling screen 2 away from the feed pipe 7. The material discharge port 5 and the debris discharge port 6 are separated by a partition.
[0021] Specifically, the screening mechanism includes a rotating shaft 9 and a screening plate 10. The inner cavity of the screening chamber 8 is rotatably connected to the rotating shaft 9 driven by a motor. The outer wall of the rotating shaft 9 is evenly provided with screening plates 10. The screening plate 10 is composed of screening rods 11 evenly distributed along the axial direction of the rotating shaft 9. The inner cavity of the feed pipe 7 is movably provided with an arc-shaped baffle 12 that cooperates with the screening plate 10.
[0022] In this embodiment, a groove is formed between each screening rod 11 so that small-diameter raw materials can pass through. When the rotating shaft 9 drives the screening plate 10 to rotate, the small-diameter raw materials pass through the grooves, and the large-diameter raw materials remain on the screening plate 10. When the screening plate 10 rotates to the discharge port 22, the raw materials are discharged from the discharge port 22 along the screening plate 10.
[0023] Specifically, a notch is provided on the side of the feed pipe 7 for the baffle 12 to move, and the top and bottom of the baffle 12 are fixedly connected with ear plates 13 that can fit with the outer wall of the feed pipe 7.

[0025] Specifically, the diameter of one end of the rolling screen 2 close to the feed pipe 7 is larger than the diameter of the other end thereof away from the feed pipe 7 .
[0026] In this embodiment, when the rolling screen 2 rotates, the raw materials to be screened can move from the direction of the feed pipe 7 to the direction of the impurity discharge port 6 so as to be screened.
