[0062] The production process parameters of ceramic zinc oxide are input, including temperature condition T (s), time condition t and atmosphere condition A.

[0063] Step B: generation of temperature curve

[0064] According to the process parameters, the overall temperature curve of each functional area (preheating zone, sintering zone and cooling zone) is generated:

[0065] Step C: area division and weight coefficient setting

[0066] Each functional area is divided into i x j, and for i x j unit areas in each functional area, a weight coefficient is set according to the positional relationship, wherein the positional relationship of the weight coefficient includes the following factors: the distance from the kiln wall, the distance from the temperature control subunit, the air conduction characteristics and the heat conduction characteristics.

[0067] In some embodiments of the present application, the setting module further comprises:

[0068] The distance from the (i, j) unit area to the nearest kiln wall is The first weight is The first weight is calculated by the following formula:

[0069] ;

[0070] Wherein is the first adjustment coefficient, used to control the decay speed caused by the distance variation from the kiln wall, and represents the distance from the kiln wall of the (i, j) unit area.

[0071] Specifically, the kiln wall is usually colder than the central area inside the kiln, so the temperature of the unit area closer to the kiln wall is relatively low, which is represented by a decreasing function; and represents the distance from the kiln wall of the (i, j) unit area. The width of the kiln is W, the height is H, and the coordinates of the unit area (i, j) are (x, y), so the distance from the kiln wall is The kiln wall is usually colder than the central area inside the kiln, so the temperature of the unit area closer to the kiln wall is lower, and the distance from the kiln wall can be divided into the distance from the four boundaries, and the minimum value of these distances is taken as , that is The calculation is obtained by the following formula:

[0072] ;

[0073] In some embodiments of the present application, the setting module further comprises:

[0074] For a plurality of temperature control sub-units inside the kiln, the position is , the nearest distance from the corresponding (i, j) unit area to the temperature control sub-unit is denoted as , and the second weight is , which is calculated by the following formula:

[0075] ;

[0076] wherein is the second adjustment coefficient, used to control the decay speed caused by the distance variation from the temperature control sub-unit, and represents the distance between the (i, j) unit area and the nearest temperature control sub-unit.

[0077] Specifically, the temperature control sub-unit is a key device for controlling temperature, which is distributed in the kiln body 1, and the temperature of each unit area is affected by the distance from these temperature control sub-units, because the closer the distance, the more obvious the temperature control effect. The position coordinates of the temperature control sub-unit are , and the coordinates of the unit area (i, j) are . The Euclidean distance is used to calculate , that is The calculation is obtained by the following formula:

[0078] ;

[0079] wherein, ​The distance from each unit area (i, j) to all temperature control sub-units is calculated, and the minimum value is taken, so as to find the nearest temperature control sub-unit to the unit area (i, j), because the nearest temperature control sub-unit has the greatest influence on the temperature of the unit area.

[0084] Specifically, the flow of the air flow will affect the conduction of heat. Assuming that the air flow mainly flows in the x direction, the unit area closer to the air flow inlet 14 in the x direction will be more easily heated.

[0088] wherein is a constant representing the heat conduction performance weight of the kiln body 1 in the present embodiment, and a heat performance coefficient is set for different shapes or angles .

[0089] Specifically, the heat performance coefficient ​The following technical ideas are defined: when the tunnel kiln is rectangular, the thermal performance coefficient can be considered to consider the influence of the length-width ratio on heat conduction. For example, for a relatively narrow kiln body 1, the thermal performance coefficient may be lower because its heat conduction capacity may be limited under the same material thickness; for a circular tunnel kiln, the influence of its radius on heat conduction may need to be considered. The kiln body 1 with a larger radius may have higher heat conduction performance because its surface area is relatively large and can dissipate heat more effectively; tunnel kilns made of different materials have different heat conduction performance. For example, metal materials may have higher heat conduction performance, while ceramic materials may have lower heat conduction capacity. Therefore, for tunnel kilns made of different materials, different thermal performance coefficients can be set to reflect their material properties; for inclined or curved tunnel kilns, the angle may affect the way heat is conducted within the kiln body 1. Steeper angles may cause heat to conduct downward more quickly, while flatter angles may cause heat to stay within the kiln body 1 for a longer period of time. Therefore, the thermal performance coefficient can be set according to the angle of the kiln body 1 to reflect this influence.

[0090] In some embodiments of the present application, the setting module further comprises:

[0095] The temperature curve of the s-th moment of the sintering zone is T s (s), wherein the unit area temperature curve of the preheating zone at the (i, j) is T s,ij (s)=T s (s)× ;

[0096] The temperature curve of the s-th moment of the cooling zone is T c (s), wherein the unit area temperature curve of the preheating zone at the (i, j) is T c,ij (s)=T c (s)× ;

[0097] In particular, the embodiment relates to a tunnel kiln device for directly producing ceramic zinc oxide, comprising a kiln body 1, a setting module and a control module. A plurality of functional areas are provided, each of which has a temperature control unit, including a plurality of temperature control sub-units. The setting module is used to obtain quality standards in the ceramic zinc oxide production process, and generate production requirement information in each functional area according to the standards. The control module controls the temperature of the temperature control sub-units according to the production requirement information.

[0098] In the embodiment, the kiln body 1 comprises a preheating zone, a sintering zone and a cooling zone, and a plurality of unit areas are provided in each zone, each of which has a corresponding temperature control sub-unit and a temperature sensing unit. The setting module is used to extract key quality standards according to the ceramic zinc oxide production process parameters, including the temperature curve in each functional area. In addition, the setting module also maps the temperature curve of each unit area according to the positional relationship and weight coefficient, taking into account factors such as distance from the kiln wall, distance from the temperature control sub-unit, air conduction characteristics and heat conduction characteristics.

[0099] Specifically, the weight coefficient is set according to the position of the unit area and is obtained through a series of calculation formulas. Among them, the adjustment coefficient is used to control the influence of the change of the distance from the kiln wall or the temperature control sub-unit on the weight. These weight coefficients are used to map the overall temperature curve into the preheating zone, sintering zone and cooling zone temperature curves of each unit area. Finally, according to the temperature curve obtained by mapping, the setting module further calculates the temperature curve in each functional area, and uses it for production requirement generation and temperature control of the control module.
