Description

Technical Field

[0001] The utility model relates to the technical field of slag recovery, in particular to a slag recovery device. Background Art

[0002] Polyaluminum ferric chloride has a wide range of applications and is widely used in drinking water, industrial water, domestic sewage and industrial sewage treatment. When producing polyaluminum ferric chloride, basic aluminum chloride and basic ferric chloride solution are generally self-polymerized to form polyaluminum ferric chloride solution. The resulting solution is concentrated at a certain temperature to obtain polyaluminum ferric chloride.

[0003] The slag generated during the production of polyaluminium ferric chloride mainly includes waste residues. These waste residues are formed by the reaction of raw materials during the production of polyaluminium chloride, specifically including calcium chlorate powder, hydrochloric acid, bauxite and other materials. These waste residues are viscous, colloidal, and earthy yellow in color, and are weakly acidic and have a high water content. In previous treatment methods, these waste residues were mostly directly piled up or directly landfilled without drying. However, this treatment method is extremely harmful to the environment and land. Therefore, when recycling these waste residues, it is necessary to adopt an environmentally friendly and safe method to reduce the negative impact on the environment. In order to solve the above problems, a slag recovery device is now proposed to solve the above problems. Utility Model Content

[0004] In view of this, the utility model provides a slag recovery device, in which the slag enters the cleaning box through the slag conveying channel, and the cleaning water pump is started to supply the raw water in the water storage tank into the cleaning box through the cleaning pipe to clean and soak the slag. After cleaning, the slag will be rich in water due to its high water content, and another part of the water will be filtered through the filter and enter the circulation pipe to form circulating water and enter the water storage tank, and then be supplied into the cleaning box again through the cleaning water pump for secondary utilization. In this way, repeated cleaning is performed. When the raw water in the water storage tank is insufficient, water is replenished in the water storage tank through the raw water pipe and the second valve, which reduces the use of raw water and thus saves water resources. The discharge valve is opened to allow the water-containing slag to enter the drying silo, and the hot air unit is started to heat and enter the air diffuser through the hot air pipe. The slag is quickly dried with water through the large sweeping area of ​​the air diffuser to cause it to agglomerate, and finally the discharge door panel is opened to shovel the material and pack it.
