Squeeze type ceramic green body drying device using temperature difference and pressure

Abstract

The invention belongs to the technical field of ceramic processing, and discloses an extrusion type ceramic body drying device utilizing temperature difference and pressure. The extruded ceramic body drying device using temperature difference and pressure includes a drying box, the four corners of the lower surface of the drying box are fixedly connected with outriggers, the top opening end of the drying box is covered with a box cover, and the lower surface of the box cover A box plug is bonded, and the box plug is plugged in the inside of the drying box. The upper and lower sides of the right side of the drying box are respectively fixed with a hot air blower and a vacuum pump, and the middle part of the box cover is plugged with a heat supply pipe. The extruded ceramic embryo body drying device using temperature difference and pressure uses a vacuum pump to extract the gas in the drying box, and at the same time extracts the moisture in the air. It is quickly vaporized and separated from the green body and is drawn out of the drying oven by a vacuum pump, which helps the moisture in the ceramic green body to quickly detach, and the ceramic green body can be dried quickly.

Description

technical field [0001] The invention relates to the technical field of ceramic processing, in particular to an extruding ceramic body drying device utilizing temperature difference and pressure. Background technique [0002] Ceramic body drying refers to the process of removing moisture from the ceramic body. After drying, the strength of the green body is improved. After the green body is shaped, it is easy to carry out subsequent processing and handling. Obtaining the drying position has higher requirements on the drying process. Chinese patent (notification number CN 207422854U) discloses a ceramic body drying device, including a blower, an air duct connected to the air outlet of the blower, and the air duct has a downward direction. The air outlet pipe, the ceramic embryo body is located below the air outlet pipe, which uses a blower to blow the ceramic embryo body for a long time to dry, it is difficult to achieve uniform drying of the ceramic body during processing, an...

After the green body is shaped, it is easy to carry out subsequent processing and handling. Obtaining the drying position has higher requirements on the drying process. Chinese patent (notification number CN 207422854U) discloses a ceramic body drying device, including a blower, an air duct connected to the air outlet of the blower, and the air duct has a downward direction. The air outlet pipe, the ceramic embryo body is located below the air outlet pipe, which uses a blower to blow the ceramic embryo body for a long time to dry, it is difficult to achieve uniform drying of the ceramic body during processing, and the drying process takes a long time, Chinese patent (publication number CN 108195142 A) Disclosed is a ceramic green body drying device in the ceramic production process, which includes two support columns, on which a drying mechanism is installed, and the front and rear of the drying mechanism are respectively connected with a front drying mechanism connector and a rear drying mechanism connector. Use the drying mechanism to dry the ceramic body in all directions, but it still only realizes the drying of the body by simply accelerating the air temperature and flow rate, which takes a long time
