Description

Technical Field

[0001] This application relates to the field of gypsum mold shell firing technology, and more particularly to a gypsum mold shell firing device that is easy to control in temperature. Background Technology

[0002] In the processing of gypsum mold shells, there is a very important step, which is firing. Currently, the most common firing method is to use a firing furnace. Firing furnaces can perform high-temperature synthesis, calcination, sintering, ashing, incineration, melting, and heat treatment of various solid materials.

[0003] Currently, in the process of calcining gypsum mold shells, the gypsum mold shells are usually placed inside the calcining furnace for calcination. This process is prone to uneven heating and makes it difficult to automatically control the temperature, thus reducing the calcination effect of the furnace on the gypsum mold shells. Therefore, to solve the above problems, we provide a gypsum mold shell calcination device that is easy to control the temperature. Utility Model Content

[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

[0013] This temperature-controlled gypsum mold shell firing device uses an electric heating rod to heat and fire the gypsum mold shell above the carrier plate from the center. Activating the electric heating plate heats the exterior of the gypsum mold shell. Simultaneously, the rotating shaft and connecting cylinder work together to slowly rotate the gypsum mold shell above the carrier plate, ensuring more even heating and preventing uneven heating during firing.

Specifically, the electric heating rod 9 and the electric heating plate 3 can heat the exterior of the gypsum mold shell, and the cooperation of the rotating shaft 7 and the connecting cylinder 8 will make the gypsum mold shell heated more evenly.

[0024] In this embodiment, a drive cover 4 is fixedly installed on the upper surface of the baking cover 2, and a drive motor 5 is fixedly installed on the inner top wall of the drive cover 4. The output end of the drive motor 5 is fixedly connected to the top end of the rotating shaft 7. The upper surface of the carrier plate 12 is provided with a ring-shaped arrangement of placement grooves 21, and the outer surface of the connecting cylinder 8 is provided with a ring-shaped arrangement of baking holes 20. Specifically, the drive motor 5 can be installed through the drive cover 4, and the drive motor 5 can provide power for the rotation of the rotating shaft 7. The multiple placement grooves 21 facilitate the uniform placement of multiple plaster mold shells.

[0025] In this embodiment, an annular slide rail 11 is fixedly connected to the upper surface of the support platform 1. The upper surface of the annular slide rail 11 is slidably connected to the bottom surface of the carrier plate 12. A sealing door 17 is hinged to the front of the roasting hood 2 by a pin. A groove 18 is opened on the front of the sealing door 17. A through hole 10 is opened on the bottom surface of the support platform 1. The top end of the electric heating rod 9 passes through the through hole 10 and extends into the interior of the connecting cylinder 8.

The operation of the drive motor 5 can drive the rotating shaft 7, the connecting cylinder 8, and the plaster mold shell above the carrier plate 12 to rotate slowly, thereby making the plaster mold shell heat more evenly. Furthermore, the temperature sensor 14 can sense the temperature of the plaster mold shell during baking, resulting in better temperature control.
