[0002] The firing process of ceramic processing is a crucial part of ceramic production, which directly affects the quality and production efficiency of ceramic products. Existing ceramic firing equipment mostly adopts the traditional single-furnace design, which usually requires multiple firing furnaces to handle ceramic products of different sizes or types. For example, for small-sized ceramic products and large-sized ceramic products, two sets of side-by-side firing furnaces are often required to handle different needs respectively. However, this solution has problems such as large equipment space, high production costs, and complex control systems. Especially in a production environment with limited space and diverse production needs, it is often impossible to optimize space and costs.

[0009] 1. Low space utilization. For high-density production, it may be limited by space and cannot efficiently process ceramic products of various specifications;

[0010] 2. There are inadequate designs for waste gas recovery and thermal efficiency improvement, and there is a lack of sophisticated design for independent temperature control of different firing areas.

[0011] In addition, the existing technology for firing ceramic products of various sizes and specifications mostly uses two firing boxes side by side. The two firing boxes occupy a large space, and their control systems are independent, and centralized control cannot be achieved. Summary of the Invention

[0012] The purpose of the present invention is to provide a firing device for ceramic processing and a method for using the same.

Based on the principle that hot air rises and cold air falls, the hot air is naturally emitted from the bottom and rises upward. The post-firing chamber can be equipped with additional shelves to simultaneously process large-volume and small-volume ceramic products. The storage slots on the shelves can be used to place small-sized ceramic products, and the brackets themselves can be used to place large-sized ceramic products.

[0026] The specific technical effects include:

[0027] 1) Double-Sided Design, Saving Space and Cost: The firing device of this invention utilizes a double-sided design, with the front and rear firing chambers located on the front and rear sides of the firing furnace, respectively. Compared to two sets of firing furnaces placed side by side, this design not only reduces the use of control systems and equipment costs, but also significantly saves space. The double-sided design also prevents interference between the front and rear firing chambers, allowing ceramic products of different sizes to be processed simultaneously within the same device, improving the overall utilization rate of the equipment.

[0028] 2) Precise temperature control and rapid heating: Auxiliary heaters and thermostats are installed in both the front and rear firing chambers. Each chamber can precisely adjust the temperature as needed, achieving meticulous control over small-volume ceramic products. The heating equipment includes a heating box, an exhaust hood, and an air inlet duct. The exhaust hood ensures that the ceramic products are fully preheated by evenly supplying heat. Combined with the combined action of the main and auxiliary heaters, the ceramic products can be heated quickly, improving production efficiency.

[0029] 3) Adapt to the firing of ceramic products of different sizes: Shelves are set up in the post-firing room. Through the design of storage slots and brackets, it can adapt to the firing of both small and large ceramic products. The design of brackets and storage slots effectively improves the uniform firing effect of ceramic products. The design of the first ventilation slot and the second ventilation slot ensures that ceramic products of different sizes can obtain uniform heat distribution during the firing process.

[0030] 4) Flue gas waste heat recovery and energy saving: The design of the flue gas waste heat recovery chamber and air heat exchanger can effectively recover the waste heat generated during the firing process. The cold air is introduced into the heat exchanger through the induced draft fan, and the hot air is then returned to the firing chamber through the exhaust hood for preheating. This not only improves the utilization efficiency of thermal energy and reduces energy consumption, but also optimizes equipment operating costs.

[0031] 5) Easy Operation and Precise Control: The sealed lid assembly features a flip-open design that allows for timing according to firing requirements, making it suitable for the precise firing of small-sized ceramic products. The combination of the sealed lid assembly and the chamber temperature controller allows operators to more easily adjust the temperature and firing time of each chamber, achieving higher-precision firing operations.
