Production process of energy-saving sintered shale hollow blocks with full internal combustion once-by-combustion

Abstract

The invention discloses a full-internal combustion one-time palletizing burning production technology for energy-saving type sintered shale hollow blocks. The production technology comprises the four steps of raw material preparation and blending, blank manufacturing, drying and palletizing burning, and storing. The production technology is characterized in that firstly, the raw material preparation and blending is performed, to be specific, shale is smashed and finely ground, coal gangue is smashed and finely ground, and then the shale and the coal gangue are mixed and blended; secondly, the blank manufacturing is performed, to be specific, raw materials are subjected to aging processing, mixed and stirred, and then, the blanks are manufactured, cut, grouped and stacked; thirdly, the drying and palletizing burning are performed; finally, the obtained products are stored. According to the full-internal combustion one-time palletizing burning production technology for the energy-saving type sintered shale hollow blocks, the resources are reasonably utilized, and the automation degree is high; qualified hollow bricks can be effectively and quickly produced, so that resources are saved and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of hollow brick production, and in particular relates to an energy-saving sintered shale hollow block full internal combustion once-stacked production process. Background technique [0002] Hollow bricks are made of clay, shale, etc. as the main raw materials, after raw material processing, molding, and sintering. The advantages of hollow bricks are light weight, high strength, heat preservation, sound insulation and noise reduction performance. The use of hollow bricks is very scientific, and the quality requirements are also high. It is related to the investigation of whether the foundation is suitable for using hollow bricks, how to design them, and whether there are any problems with cement and other related ingredients during construction. At present, although the production technology of sintered shale hollow blocks is relatively advanced in China, it is still relatively backward compared with develop...

AI Technical Summary

Problems solved by technology

At present, backward natural stacking or semi-mechanization is generally used for powder aging. The plasticity, viscosity, muddyness, and uniformity of the aged powder are poor, and the particle gradation and moisture content of the powder are difficult to control and cannot be produced. Energy-saving sintered shale hollow blocks with a high void rate. At the same time, the aged powder needs to be rolled with high-power-consuming rolling equipment before it can be used. However, enterprises generally use secondary sintering to produce sintered shale hollow blocks. Blocks generally can only produce sintered shale hollow blocks with less than 30 holes and a porosity of about 40%. However, the hollow bricks produced by the secondary firing process cannot meet the technical requirements of building energy saving of 65%, and waste of resources is relatively high. Many, high cost, so people in this field are eager to research a production process for hollow bricks with high porosity with less process flow, rational use of resources and energy, and cost savings. 50% high porosity hollow brick
