Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sintering mixers, and particularly relates to a non-powered self-cleaning sintering mixer water beam and a material accumulation alarm system thereof. BACKGROUND

[0002] As a core equipment of a high-quality sinter production line, the sintering mixer is responsible for the sintering mixing process, which mainly functions to effectively mix and granulate the sintering raw materials such as mixed materials, coke powder, dolomite, quicklime and returned ore, which have completed the process proportioning, while rotating with the sintering mixer. The sintering mixer water beam, as a key component of the sintering mixer, directly determines whether the sintering mixing process can proceed smoothly.

[0003] Due to the high proportion of dolomite and quicklime in the sintering raw materials and the sticky nature of the sintering raw materials themselves, the traditional sintering mixer water beam, which needs strong bearing capacity due to the fixed water pipe and other devices, is usually made of rigid stainless steel material to form a rigid body structure and is arranged in the sintering mixer cylinder. When the sintering raw materials in the sintering mixer cylinder rotate with the sintering mixer cylinder, they are affected by gravity, fall and adhere to the surface of the water beam, continuously accumulate and harden to form large material accumulation lumps in a long maintenance period, causing the material accumulation problem of the sintering mixer water beam.

[0004] The material accumulation problem of the traditional sintering mixer water beam has three aspects. First, the large and heavy material accumulation lumps (weighing up to 7-8 tons) cause permanent deformation of the water beam, resulting in excessive deflection and irreversible damage to the equipment. Second, the material accumulation lumps are easily detached from the sintering mixer water beam during the maintenance period, causing blockage of the discharge outlet. The detachment of the material accumulation lumps (with a volume of up to 800mmx500mmx500mm) causes blockage of the discharge outlet of the sintering mixer, leading to shutdown of the sinter production line. Since the single fault handling time is not less than 2 hours, the production of the sinter production line fluctuates, and the cleaning and removal of the material accumulation lumps are time-consuming and labor-intensive, which not only has certain safety hazards but also causes environmental pollution. Third, the hardness of the falling material accumulation lumps causes damage to the lining plate and hopper, increasing the maintenance workload, restricting the maintenance progress of the sinter production line, and causing a sharp increase in the cost of spare parts for the sinter production line.
