Description

TECHNICAL FIELD

[0001] The utility model relates to electric kiln equipment technical field, concretely is a kind of auxiliary tool for purple sand teapot firing. BACKGROUND

[0002] After purple sand teapot blank is shaped by hand, dried and the like, it needs to be fired at high temperature to realize the physical and chemical conversion of mud material, and finally form the compact and hard finished product.In modern technology, electric kiln becomes the core equipment of purple sand teapot firing due to its precise temperature control ability, stable heating environment and convenient operation.Electric kiln can accurately simulate the temperature rising curve (such as oxidation and reduction stage) of traditional charcoal kiln, while avoiding impurity pollution caused by direct contact of open fire, ensuring the pure color and uniform shrinkage of purple sand teapot, and significantly reducing the risk of firing defects (such as cracking and deformation).

[0003] The existing electric kiln for purple sand teapot firing is mainly composed of electric kiln main body, heat insulation layer, flip cover design, electric heating system, boron plate and other core components.The electric kiln main body adopts a composite structure of high-temperature-resistant metal frame and ceramic fiber material to form a closed heating chamber.The heat insulation layer is embedded in the cavity wall of the electric kiln main body and is composed of multiple layers of ceramic fiber or alumina material to reduce heat loss and maintain the stability of the cavity temperature.The kiln door is of flip cover structure, and the inner side is also covered with a heat insulation layer, which tightly fits with the heat insulation layer inside the main body when closed to prevent heat loss.The heat insulation layer has uniform horizontal grooves inside, and high-resistance heating wires (such as nickel-chromium alloy material) are embedded in the grooves.The wires are connected to an external control terminal through wires, and the heating wires are distributed according to areas to support temperature zone control, ensuring the uniformity of the heat field in the cavity.The boron plate is placed at the bottom of the electric kiln main body chamber and is a porous plate made of refractory material (such as silicon carbide or cordierite) to support the purple sand teapot blank.The plate is spaced a certain distance from the electric heating system to avoid direct contact between the blank and the heat source, while allowing hot air circulation and penetration to achieve all-around heating.Through the above structure, the electric kiln can accurately execute the preset firing curve (such as temperature rising rate and holding time) and adapt to the characteristics of purple sand mud (such as shrinkage rate and sintering temperature) to ultimately ensure the quality of the finished purple sand teapot.

[0004] However, the existing electric kiln equipment for purple sand teapot firing still has the following shortcomings:Firstly, the existing electric kiln equipment for firing needs the operator to open the flip cover to take out the purple sand teapot from the inner wall of the electric kiln main body with a certain depth after firing is completed, but the inner wall of the electric kiln main body is installed with a heat insulation layer, so the firing space is relatively narrow and small, and the surface temperature of the fired purple sand teapot is high.The operator needs to put his hand deep into the electric kiln main body to take out the purple sand teapot with a tool or heat-resistant gloves, which is not only cumbersome but also may cause burns if not careful, posing a great safety hazard.
