Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a raw material screening device for producing furnace core bricks. Background Art

[0002] Small man-made blocks used in construction are divided into sintered bricks (mainly clay bricks) and unsintered bricks (lime sand bricks, fly ash bricks, etc.), commonly known as bricks. Among them, furnace core bricks are a type of sintered bricks. Clay bricks are made of clay (including shale, coal gangue and other powders) as the main raw material, and are made through mud processing, molding, drying and baking. China successively created square and long bricks during the Spring and Autumn Period and the Warring States Period. During the Qin and Han Dynasties, the technology, production scale, quality and variety of bricks were significantly developed, and they were known as "Qin bricks and Han tiles".

[0003] After searching: the authorization publication number is CN214975649U, which is a raw material screening device for building brick production. The raw material screening device for building brick production includes a machine table, a support frame is welded to the top surface of the machine table, a spring frame is bolted to the top of the support frame, a filter box is bolted to the top of the spring frame, a mounting seat is welded to the top of the machine table, and a belt feeder is bolted to the top of the mounting seat.

[0004] However, the above-mentioned raw material screening device for building brick production still has some shortcomings. First, it only uses a vibrating machine for vibration screening, which leads to poor screening effect and low efficiency. At the same time, a large amount of flying dust is easily generated during screening, and the flying dust overflows to the outside and easily causes environmental pollution. Therefore, we propose a raw material screening device for furnace core brick production to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the above-mentioned shortcomings and proposes a raw material screening device for furnace core brick production.
