Embodiment 1

[0047] The invention discloses a production process of antique green bricks, which comprises the steps of raw material treatment, billet making, drying, firing and drying.

[0048] Wherein, the raw material processing process includes raw material preparation and raw material stirring. During the raw material stirring process, steam is passed on the raw material while stirring. After the raw material stirring process is completed, the water content of the raw material is 16%-20%.

[0049] The present embodiment prepares 5 kilns respectively with water mixing process and steam mixing process and compares (other conditions are consistent, including mixing time), observes the surface and the section surface of the blue brick produced, and the blue brick prepared by steam mixing process, Its organizational structure is more consistent, the particles are consistent, the color is uniform, and the size of the pores is uniform; while the blue bricks mixed with water have some inclusion...

Embodiment 2

[0060] In order to implement the aforementioned process, the present invention also discloses an antique blue brick production equipment, which includes a double-screw mixing conveyor, a steam supply device, a screw conveyor, a heating room, a billet making machine and a drawer kiln.

[0061] Please refer to figure 1 , figure 2 and image 3 As shown, the two side walls of the double-screw mixing conveyor 1 are provided with a steam inlet 11, and the setting height H of the steam inlet 11 meets H1≤H≤(H1+H2), and the H1 is the screw shaft of the double-screw mixing conveyor 1 The height of the shaft center, the H2 is the height from the shaft center of the screw shaft to the center of the uplift of the material when the double-screw mixing conveyor is working. The steam supply device 2 supplies steam to the double-screw mixing conveyor 1 through the steam inlet 11 .

[0062] In this way, when the double-screw mixing conveyor 1 is working, the screw shaft on the left side run...

Abstract

The invention discloses an archaistic black brick production process. The archaistic black brick production process comprises the procedures of raw material processing, blank making, drying, firing and drying, wherein the raw material processing step comprises raw material preparing and raw material stirring, in the raw material stirring process, steam is introduced while raw materials are stirred, and after the raw material stirring process is completed, the water content of the raw materials is 16%-20%. Meanwhile, the invention further discloses equipment for realizing the process. In the raw material processing process, different from a conventional mode of directly adding water, stirring and mixing, a mode of adding steam while stirring is adopted for humidifying, so that the raw materials are fully mixed, meanwhile, water is more uniformly distributed in the raw materials, and the phenomenon of clumping can be effectively prevented, so that the color uniformity, flatness and mechanical properties of the fired black bricks are improved.

Description

technical field [0001] The invention relates to the field of green brick production, in particular to an antique green brick production process and equipment. Background technique [0002] Green bricks are fired from clay, which is the product of long-term weathering of certain aluminosilicate minerals, so it is named after its strong viscosity. The clay is mixed with water to make bricks, which are calcined in a brick kiln. Since the clay contains iron, it will produce red iron oxide when it is completely oxidized during the firing process, which is the most commonly used red brick; Add water to cool, so that the iron in the clay is not completely oxidized (Fe 3 o 4 ) is blue, that is, blue bricks. [0003] Green bricks have the advantages of high density, good frost resistance, no deformation, and no discoloration. At the same time, they have strong ancient charm. They are ideal materials for antique house walls and antique pavement decoration. [0004] Green bricks ha...
