2results about How to "Drying stability" patented technology

The application relates to a phosphogypsum cross-flow flash drying system and process, which comprises a hot blast stove, a first cyclone, a V-type powder concentrator, a dynamic powder concentrator, a second cyclone and a dust collector; the air outlet of the hot blast stove is communicated with the air inlet of the first cyclone, and is used for providing hot air to the first cyclone; the discharge port of the first cyclone is communicated with the feeding port of the V-type powder concentrator; the air outlet of the V-type powder concentrator is communicated with the air inlet of the dynamic powder concentrator; the air outlet of the dynamic powder concentrator is communicated with the air inlet of the second cyclone; the second cyclone is used for deep drying of screened phosphogypsum; and the second cyclone is further communicated with the dust collector and the air inlet of the first cyclone. The scheme provided by the application realizes efficient, energy-saving, stable and continuous drying of phosphogypsum through multi-stage cross-flow drying, grading separation, crushing and backflow, double-path waste heat circulation, dispersion, heat exchange and grading of the material in the airflow, and backflow and re-drying of large particles after crushing.

The utility model relates to the field of copper clad plate gluing and drying, especially to a copper clad plate gluing and drying device. It comprises a feeding roll, a material receiving roll and a drying box. A first gluing roller and a second gluing roller are horizontally arranged on one side below the feeding roll, and the first gluing roller and the second gluing roller extend into a gluing groove. The material receiving roll is arranged on one side above two limiting transmission rollers. Electronic glass fiber cloth is sequentially immersed in the gluing groove through the first gluing roller and the second gluing roller from the feeding roll. The feeding roll and the material receiving roll are driven to rotate by a motor. The device uses negative pressure to form an air duct for drying. The opening of the air outlet faces downward, and the arc-shaped air outlet guide surface on one side can make the air outlet larger, so that the air speed of the air duct is smaller. The air inlet groove is provided with multiple air inlets, and the shape of the air inlet groove is an arc that curves upward. Hot air that goes out of the air inlet groove will be guided to move obliquely upward. The multiple air inlets can not only prevent the hot air from being directly blown but also make the drying process more gentle.
