[0024] Please refer to Figure 1 , 2 , 3, 4, 5, 6 as shown, the present utility model provides a technical solution: a green body drying device for ceramic production, comprising: a drying oven 1, the interior of the drying oven 1 is provided with a receiving cavity, and the interior of the receiving cavity is provided with a heat insulation layer of foam insulation material. One end of the drying oven 1 is rotatably connected with a box door 2. The inner sides of the box door 2 and the drying oven 1 are both provided with arc plates 12. The centers of the arc plates 12 and the center of the hollow pyramid 9 are on the same vertical line. Electric heating plates 13 are equidistantly arranged on the outer sides of the arc plates 12 for providing drying heat; a placement mechanism is placed in the drying oven 1. The placement machine includes a transmission pipe 16 rotatably arranged inside the drying oven 1. The outer side of the transmission pipe 16 is fixedly connected with a rotating table 15. The top of the rotating table 15 is rotatably connected with a plurality of frosted outer wheels 17 for placing green bodies; a gas circulation mechanism is placed on the top of the drying oven 1. The gas circulation mechanism includes a hollow pyramid 9 for driving the transmission pipe 16 and a fan 11 for circulating gas. A driving part for driving the hollow pyramid 9 to rotate is arranged on the outer side of the hollow pyramid 9. When the driving part drives the transmission pipe 16 to drive the rotating table 15 to rotate, the rotating table 15 drives the frosted outer wheels 17 to rotate by rubbing against the arc plates 12.

[0025] It should be noted that in the present utility model, the green body is placed above the frosted outer wheel 17 at the top of the rotating table 15, and then the rotating table 15 is pushed into the drying oven 1. The oven door 2 is closed, and the driving part moves downward, so that the hollow pyramid 9 is inserted into the top of the transmission pipe 16. The driving part drives the transmission pipe 16 to rotate through the hollow pyramid 9, the transmission pipe 16 drives the rotating table 15 to rotate, and the rotating table 15 contacts the arc-shaped plate 12. When the transmission pipe 16 drives the rotating table 15 to rotate, the frosted outer wheel 17 and the arc-shaped plate 12 rotate by friction, thereby realizing the rotation of the frosted outer wheel 17 while revolving. The electric heating plate 13 dries the green body at the top of the frosted outer wheel 17. During this period, the blower 11 sends the heat inside the drying oven 1 into the transmission pipe 16, and the heat is dissipated through the exhaust port on the outer side of the transmission pipe 16, thereby realizing heating both in the middle and at the edge and ensuring the uniformity of heat reception.

[0027] It should be noted that the bottom of the base 14 of the present utility model is provided with rollers, which facilitates the movement of the base 14. The transmission pipe 16 is rotatably installed on the top of the base 14. When the base 14 is placed inside the drying oven 1, the positioning guide rail 20 is located inside the roller, thereby limiting the position of the base 14. When the rotating table 15 fits with the inner wall, the base 14 is installed in place, and the base 14 is fixed in the drying oven 1 by the extrusion of the oven door 2. At this time, the center of the transmission pipe 16 corresponds to the hollow pyramid 9, which facilitates the downward cooperation of the hollow pyramid 9 with the transmission pipe 16.

[0031] It should be noted that in the present utility model, the telescopic movement of the cylinder 5 drives the lifting of the lifting plate 4, and the lifting plate 4 drives the hollow pyramid 9 to lift, so as to realize the cooperation and separation of the hollow pyramid 9 and the transmission pipe 16. When the hollow pyramid 9 moves downward, it inserts into the top of the transmission pipe 16, and drives the transmission pipe 16 to rotate through the hollow pyramid 9. When the hollow pyramid 9 is separated from the transmission pipe 16, the transmission pipe 16 and the rotating table 15 can be pulled outwards.
