Description

Technical Field

[0001] The invention relates to a porcelain embryo drying device and a drying method for ceramic processing, belonging to the technical field of ceramic processing. Background Art

[0002] Ceramics is a general term for pottery and porcelain. Any object made from two different types of clay, pottery clay and porcelain clay, through a series of processes including mixing, shaping, drying, and firing can be called ceramic. After the pottery is finished, it needs to be dried.

[0003] Patent application publication number CN209751624U discloses a ceramic embryo drying device for ceramic processing, comprising a drying barrel and a ceramic embryo body. A drying device is connected to the middle of the left side of the drying barrel. The drying device includes a hot air box. The right side of the hot air box is welded to the left side of the drying barrel. The inner wall of the hot air box is connected to an electric heating wire. The top and bottom of the right side of the hot air box are both connected to a hot air duct. The right side of the hot air duct passes through the left side of the drying barrel and extends into the inner cavity of the drying barrel. When the device is in use, the counterweight wheel sequentially presses down the trapezoidal blocks, which in turn pulls the lifting rod downward, thereby moving the support plate downward, and then the support plate moves away from the ceramic embryo body, so that the bottom of the ceramic embryo body can be dried conveniently. This device can quickly and easily dry the ceramic embryo, significantly improving the yield rate of ceramic processing. Although the above device can dry the bottom of the ceramic, because the ceramic needs to be placed, the placement will be blocked, which will affect the drying process.

[0030] See also Figure 1 、 Figure 2 and Figure 5A technical solution for a ceramic embryo drying device for ceramic processing: A ceramic embryo drying device for ceramic processing includes a drying box 1, a placement component 2 arranged on the bottom surface of the drying box 1, and a drying component 3 assembled on the inner wall of the drying box 1.

The receiving ring 21 is fixedly connected to the mounting seat 24, the power box 23 is arranged on the top surface of the mounting seat 24, the receiving plate 22 is connected to the top of the power box 23, and the power mechanism in the power box 23 drives the receiving plate 22 to perform a cyclic lifting movement. When the receiving plate 22 rises to the highest point, it is higher than the top surface of the receiving ring 21. When the receiving plate 22 drops to the lowest point, it is lower than the bottom surface of the receiving ring 21;

[0031] The drying assembly 3 is composed of a first drying mechanism 31 and a second drying mechanism 32. The first drying mechanism 31 is arranged at the top of the drying box 1 and is located directly above the porcelain embryo; the second drying mechanism 32 is arranged at the inner end of the drying box 1 and is located to the side of the porcelain embryo.

The cylinder 35 is electrically connected to the detection unit.

[0032] By changing the distance between the infrared lamp 34 and the surface of the porcelain embryo, when a certain surface of the porcelain embryo is convex or concave, the infrared lamp 34 at that location is retracted or extended accordingly, keeping the distance between the infrared lamp 34 and the surface at that location the same as that at other locations.

[0033] See also Figure 3 and Figure 4A cam 25 is assembled in the power box 23, and the cam 25 is powered by an external first motor 26. A moving seat 27 is provided in the power box 23, and the cam 25 is located below the moving seat 27. A plurality of connecting rods 28 are provided on the top surface of the moving seat 27.

[0038] In step 2, the detection unit performs non-contact detection on the surface contour of the ceramic embryo and sends the contour information to the drying component 3. The infrared heating lamp 34 on the first drying mechanism 31 descends to the mud mold mouth of the ceramic embryo. The second drying mechanism 32 compares the received detection data with the current corresponding ceramic embryo surface and adjusts the position of each infrared heating lamp 34 on the second drying mechanism 32; the temperature of the infrared heating lamp 34 on the first drying mechanism 31 is 50-70 degrees, and the temperature of the infrared heating lamp 34 on the second drying mechanism 32 is 60-70 degrees.

[0039] Step three, the receiving ring 21 rotates to drive the porcelain embryo to rotate slowly and heat evenly. After the receiving ring 21 rotates one circle, the receiving plate 22 starts to rise. The receiving plate 22 rises and contacts the bottom surface of the porcelain embryo and continues to drive the porcelain embryo to separate from the receiving ring 21. After the receiving plate 22 receives the porcelain embryo and rotates one circle, the receiving plate 22 starts to descend. The time for the receiving ring 21 to rotate one circle is 3 minutes.
