Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of waste slag cooling, and particularly relates to a waste slag water quenching treatment equipment for zinc oxide production. BACKGROUND

[0002] A rotary kiln is a commonly used device for zinc oxide production. The furnace body is a long steel cylinder, which is lined with refractory material. The furnace body is supported on several pairs of supporting wheels. The furnace body is slowly rotated by a motor through a gear. The material is added from the higher tail end, and the waste slag is directly discharged from the lower furnace head end after high-temperature calcination and reduction of the oxidation. The existing treatment method for high-temperature waste slag is to directly pour it into water for rapid cooling to form water quenched slag. The water quenched slag has high recycling value. For example, low-iron water quenched slag can be used to prepare cement, environment-friendly bricks, etc., and high-iron water quenched slag can be used as raw material for blast furnace system to recover iron.

[0003] The patent application file with publication number CN117403072A discloses a waste slag treatment equipment for zinc oxide production, which includes a treatment pool and a slag discharge bin for discharging waste slag. A cooling zone for rapidly cooling high-temperature waste slag and a water storage zone for naturally cooling water after absorbing heat are arranged on the treatment pool. A sliding mechanism is arranged above the cooling zone, and the slag discharge bin is slidingly arranged on the sliding mechanism. A partition plate one is arranged in the cooling zone. The movable discharging avoids the accumulation of waste slag in the cooling chamber, which affects the cooling effect. The high-temperature waste slag entering the cooling chamber can be rapidly cooled, and the rapidly cooled waste slag can be directly discharged from the cooling chamber and further crushed, avoiding the overflow of water in the cooling chamber due to the deposition of waste slag, prolonging the replacement cycle of the cooling water in the cooling chamber, and improving the waste slag treatment efficiency. The device lacks water draining treatment of the waste slag, like the existing water quenching treatment system. A large amount of cooling water is discharged from the treatment pool with the water quenched slag, which not only wastes water resources, but also prolongs the drying period of the water quenched slag, which is not conducive to subsequent recycling. In addition, the escaped water vapor carries a large amount of cooling water and heat, causing a large amount of energy loss.

[0004] Therefore, the present application provides a waste slag water quenching treatment equipment for zinc oxide production, which can effectively solve the above problems. SUMMARY

After adding a proper amount of waste residue from the feeding funnel into the water quenching cylinder, the first cylinder is started, the sealing plate is driven to slide, the through hole is completely disengaged from the feeding funnel, the water quenching cylinder is sealed, the first circulating device is started, the cooling water in the water storage tank is added into the water quenching cylinder to contact the waste residue, and the waste residue is subjected to water quenching and cooling treatment.
