Method for improving quality of brick and tile products and gas feeder

Abstract

The invention relates to a method for improving quality of brick and tile products and a gas feeder so as to manufacture building materials of high quality. The method comprises the step of feeding steam with the pressure higher than 0.4 MPa into materials in the middle of an upper-stage agitating tank or a common agitator of a vacuum extruder during production of brick and tile products. The gas feeder for implementing the method is provided with a steam boiler. A gas feeding tube of the gas boiler is connected with a gas separation cylinder, and the gas separation cylinder is provided with an agitating tube which is used for feeding steam into the materials in the middle of the upper-stage agitating tank or the common agitator of the vacuum extruder. According to the method for improving quality of brick and tile products and the gas feeder, heating steam is fed into pug in the process of the extruder or agitator, so that the materials can be melted and resolved in winter, and the method and the gas feeder have great significance in production of high-grade products and achieving of novel wall materials and energy-saving buildings.

Description

technical field

[0001] The invention belongs to the field of sintered wall material production, in particular to a method for improving the quality of mud blanks extruded by vacuum extruders and mixers. Background technique

[0002] In recent years, with the further advancement of the national wall reform policy, a reform of wall materials with the theme of "prohibiting solids and limiting stickiness, energy saving and waste" has been fully launched in my country's brick and tile industry, especially the national third-step construction The design standard of 65% energy saving requires the characteristics of a single material such as low thermal conductivity, good thermal performance, and high porosity. Only by developing sintered thermal insulation blocks can energy saving, light weight, and thin walls be achieved. Sintered thermal insulation block is a high-grade, high-grade, high-value-added product. It is large, light, and thin-walled, and it is difficult to form. The tra...

Embodiment Construction

[0009] The method for improving the quality of brick and tile products is to pass water vapor with a pressure greater than 0.4 MPa into the middle part of the upper mixing tank of the vacuum extruder or the middle part of the ordinary mixer during the production of the brick and tile products.

[0010] The basic structure of the gas supply device is shown in the figure. It has a steam boiler 9 (vertical coal-fired steam boiler). The gas supply pipe 10 of the steam boiler 9 is connected to a sub-cylinder 13. The middle part of the superior mixing tank of the machine or the stirring tube in the raw material in the middle part of the ordinary mixer. The agitating tubes include the first agitating tube 15 for supplying air to the first agitator, the second agitating tube 16 for aerating the secondary agitator, the upper agitating tube 17 for the extruder superior agitating and aerating, and the first agitating tube 15. The second stirring pipe 16 and the upper stirring pipe 17 of ...
