Problems solved by technology

During the production and processing of brown fused alumina, more brown fused alumina dust will be formed. These brown fused alumina dusts are usually discarded directly, which will cause environmental pollution and waste of related materials, which is not conducive to environmental protection and energy saving.

Embodiment 1

[0033] Taking embodiment 1 as an example, a kind of lightweight brick production method comprises the following steps:

[0034] A. Feeding: According to the above-mentioned raw materials, pour them into the hopper through shipment, and evenly add the materials into the pouring mixer after automatic measurement;

[0035] B. Stirring: add water to make the raw material into a slurry, fully stir evenly;

[0036] C. Pouring: pour the stirred slurry into the prepared mold in turn;

[0037] D. Demoulding: After a period of time, after the green body solidifies and reaches the cutting strength, demoulding is carried out;

[0038] E. Cutting: The green body after demoulding is sent to the cutting equipment line for vertical cutting and cross cutting, and made into corresponding product specifications;

[0039] F. Stacking: The cut products are transported to the finished product stacking area and placed neatly one by one;

[0040] G. Sintering: Put the neatly arranged products into...

Embodiment 4

[0049] In step C, during the process of pouring the slurry into the mold cavity of the mold, sometimes the material will be spilled outside the mold cavity, at this time, it is necessary to manually sweep the spilled material on the mold into the mold cavity , the operation is troublesome. Therefore, this embodiment discloses a mold. By improving the structure of the mold, the material spilled outside the mold cavity can be automatically swept into the mold cavity.

[0050] Basic as attached Figure 1-Figure 2 As shown, a mold includes a plate body 1, a mold cavity 8 is provided on the top of the plate body 1, and a ring gear 2 is rotatably connected to the top of the plate body 1. The ring gear 2 is an external gear ring, and the mold cavity 8 is located At the central part of the ring 2, the rotation mode of the ring gear 2 is as follows: the top of the plate body 1 is provided with an annular groove, and the ring gear 2 is slidably installed in the annular groove. A motor ...

Abstract

The invention relates to the field of light bricks, in particular to a light brick and a production method thereof.The light brick comprises 20-40 parts of brown fused alumina recycled powder, 10-45 parts of light aggregate, 30-50 parts of dry ash and 5-15 parts of light aggregate; the brown fused alumina recovery powder is prepared from the following components in parts by weight: 29 to 31 parts of Al2O3, 38 to 39 parts of SiO2, 16 to 17 parts of K2O, 3 to 4 parts of Fe2O3, 0.5 to 1 part of TiO2, 0.5 to 1 part of MgO, 0.1 to 0.2 part of CaO and 0.5 to 1 part of Na2O; the light brick production method comprises the following steps of A, feeding, B, stirring, C, pouring, D, demolding, E, cutting, F, stacking and G, sintering. According to the scheme, the brown fused alumina powder is recycled, and meanwhile, the performance of the light brick is improved.

Description

technical field [0001] The invention relates to the field of lightweight bricks, in particular to a lightweight brick and a production method thereof. Background technique [0002] Brown corundum, commonly known as corundum, is a brown artificial corundum obtained by melting and reducing three raw materials of bauxite, carbon material and iron filings in an electric arc furnace. Brown corundum is the most basic abrasive, and it is widely used because of its good grinding performance, wide application range and low price. During the production and processing of brown fused alumina, more brown fused alumina dust will be formed. These brown fused alumina dusts are usually discarded directly, which will cause environmental pollution and waste of related materials, which is not conducive to environmental protection and energy saving. Contents of the invention [0003] The present invention intends to provide a lightweight brick and its production method, so as to realize the r...
