The invention discloses a three-layer flow-extending snowflake-shaped glaze processing technology, which is characterized in that through cooperative work of matched processing equipment, a layered glazing and staged firing technology is combined to form runner, pinniform and snowflake-shaped three-layer glaze with clear layers, and through matching with a transparent glaze layer, the glossiness and the stability are improved. According to the technical scheme, the method is characterized in that the method is based on three-layer flow-extending snowflake-shaped glaze line machining related equipment, and the equipment comprises a ball mill, rolling forming equipment, a ventilation drying device, a rotary workbench, a feather-shaped smearing tool, kiln equipment and glaze dipping equipment; the aeration-drying device is used for adjusting the moisture content of a mud blank, the rotary workbench is used for fixing the disc body during glazing, the feather-shaped smearing tool is used for layered glazing, the kiln equipment is used for staged temperature control firing, and the glaze dipping equipment is used for applying transparent glaze; the method comprises the steps of pre-preparation, layered glazing, staged firing and transparent glaze layer forming.

The invention belongs to the technical field of solid waste resource utilization, and particularly relates to a pinniform non-cemented gangue paste filling treatment system and a treatment method utilizing the pinniform non-cemented gangue paste filling treatment system, the pinniform non-cemented gangue paste filling treatment system comprises a pinniform underground filling device, a ground input device and a control display, and the control display is wirelessly connected with an upward input device; the ground input device comprises a storage bin, a discharging port of the storage bin is connected with a three-way rotary distribution valve through a feeding pipeline, three pipe openings of the three-way rotary distribution valve are a feeding port, a discharging port and an overflow port respectively, and the three pipe openings correspond to the feeding pipeline, the discharging pipeline and the overflow pipeline in a one-to-one mode and are fixed through pipe hoops. A pressure detection device is welded on the feeding pipeline; according to the application of the device, goaf areas of different waste old roadways can be flexibly filled at the same time, the efficiency is high on the premise that a coal face is not affected, the adopted pressure detection device is simple in structure, an inner core body of the pressure detection device directly makes contact with a medium, the reliability of a detection result is greatly improved, and errors are effectively reduced.
