Description

Technical Field

[0001] The invention relates to the field related to lithium slag bricks, in particular to a device for pressing and forming lithium slag bricks. Background Art

[0002] Lithium slag comes from the lithium salt production process, which is divided into acidic slag and alkaline slag. Acidic lithium slag is the waste slag produced when lithium carbonate is produced by sulfuric acid method. It is produced after lithium concentrate is roasted at 1300℃ and acidified, leached under normal pressure, and separated by liquid and solid. Acidic lithium slag is an active mixed material with extremely low alkali content. Using lithium slag to produce cement bricks can not only achieve the purpose of comprehensive utilization of industrial waste slag to turn harm into benefit, but also increase the output of cement bricks, reduce production costs, improve the performance of cement bricks, adjust the grade of cement bricks, and improve the safety of cement bricks; it can also manufacture high-strength cement brick piles. For cement unfired bricks, when the optimal ratio of cement-based binder is 80%, 10%, and 10% for cement bricks, fly ash, and slag powder respectively; the increase in the amount of cement-based binder can significantly improve the strength, water resistance, and frost resistance of lithium slag unfired bricks.

[0003] In the production process of unfired cement bricks, molding equipment is used during molding; currently, the molds for producing square cement bricks are generally fixed-size molds, and different-sized bricks require different molds; it is difficult to achieve that the same mold can adapt to the production of square bricks of different sizes at the same time. Even if there is an adjustable mold as described above, it is still a big problem to realize the automation of the adjustable mold.

[0004] In addition, the upper mold is generally used to press the lower mold during molding. After molding, the lower mold is flipped to pour out the bricks. This demoulding method increases the complexity of the mold movement and the external driving structure of the mold. At the same time, due to the existence of the flipping action, the efficiency of brick forming is reduced to a certain extent, and there is also a risk of cracking the bricks during flipping.
