Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to a dust suction connection component of a ball mill for preparing aerated concrete blocks. Background Art

[0002] Aerated concrete blocks are a new type of building material that is lightweight, porous, thermally insulating, fireproof, can be nailed, sawed, planed, and has a certain degree of earthquake resistance. It is an excellent new type of building material and has the advantages of environmental protection. The ball mill is a key equipment for crushing materials after they are broken. The aerated concrete block raw material ball mill is a ball milling equipment for finely crushing the raw materials of concrete blocks, which is beneficial to the full mixing of concrete blocks during manufacturing and achieves excellent use effects.

[0003] For example, Chinese patent CN217491086U discloses a dust removal mechanism for a ball mill, which includes a ball mill body, a support frame is provided above the ball mill body, the support frame has a cleaning brush arranged along the length direction of the ball mill body, and a height adjustment mechanism for driving the cleaning brush to approach or move away from the ball mill body; the height adjustment mechanism includes two electric telescopic rods arranged at both ends of the bottom of the support frame, the electric telescopic rods are extended and retracted toward the ball mill body, and a connecting plate is provided at the bottom thereof, and both ends of the cleaning brush are connected to the corresponding connecting plates; a dust suction component is also arranged on the support frame.

[0004] During the wet ball milling process of materials for preparing aerated concrete blocks, the ball mill usually transports the materials into the ball mill barrel through the feed end. During the continuous ball milling process, dust is usually generated at the feed end because the materials are crushed to a small particle size. Generally, the ball mill is equipped with a dust suction mechanism at the feed end to prevent dust diffusion and reduce dust pollution. However, since the materials are crushed to a small particle size and the dust suction mechanism is not sufficiently sealed when connected to the feed end of the ball mill, some dust is not removed in time and diffuses to the surrounding environment, causing dust to float in the air, causing environmental pollution, and thus being easily inhaled by surrounding staff, increasing safety hazards for staff. In view of the above problems, a dust suction connection component for a ball mill for preparing aerated concrete blocks is proposed. Utility Model Content
