Embodiment 1

[0036] see Figure 6 , is a flowchart of an intelligent control method for the drying end point of sintered fuel provided by this application. Such as Figure 6 As shown, the method includes:

[0037] 601. Acquire the current weight of the sintered fuel according to a preset period.

[0038] Material is a technical term in the field of production. Production enterprises are accustomed to refer to all materials that circulate in the production field other than the final product, including fuel, parts, semi-finished products, outsourcing parts, and leftovers, waste materials and various wastes that are inevitably generated during the production process. ". Obtaining the current weight of the sintered fuel is during the microwave drying process of the sintered fuel. When the microwave drying is too heavy, the current weight of the sintered fuel is continuously obtained according to the preset cycle. The preset period can be determined according to the water content of the s...

Embodiment 2

[0051] see Figure 7 , is a flow chart of another intelligent control method for the drying end point of sintered fuel provided by this application. Such as Figure 7 As shown, the method includes:

[0052] 701. Obtain the initial weight of the sintered fuel.

[0053] Obtaining the initial weight of the sintered fuel before starting drying makes the calculated drying rate results more accurate. Specifically include: if a drying start instruction is received, generate a mass acquisition instruction, which is used to acquire the weight of the sintered fuel; respond to the mass acquisition instruction, find the current weight of the sintered fuel; determine the search result as the initial weight. The drying start instruction can be generated by the user operating the external button of the microwave drying equipment, or it can be sent remotely by the user through a wireless terminal, or it can be automatically generated after the previous processing of the sintered fuel is co...

Embodiment 3

[0068] see Figure 8 , is a flow chart of another intelligent control method for the drying end point of sintered fuel provided by this application. Such as Figure 8 As shown, the method includes:

[0069] 801. Acquire the current weight of the sintered fuel according to a preset period.

[0070] During the microwave drying process, the water content of the sintered fuel is constantly changing. The weight of the sintered fuel is continuously obtained according to the preset period, so as to grasp the drying condition of the sintered fuel in real time. The preset period can be determined according to the water content of the sintered fuel, the drying rate, and the total mass of a single microwave drying. In the embodiment of this application, there is no limitation on the determination and placement of the preset period. The preset period may be a fixed value or a variable value, which is not limited in this embodiment of the present application. Since during the drying p...

Abstract

The invention discloses an intelligent control method and device for a sintered fuel drying end point, relates to the technical field of automatic control, and aims to solve the problem in the prior art that the safety risk of determining drying time according to manual experience is high. The method comprises the following steps: acquiring the current weight of a sintered fuel according to a preset period; calculating current drying rate according to a preset drying rate formula; judging whether the current drying rate is smaller than the drying rate of the previous period or not; if the current drying rate is smaller than the drying rate of the previous period, then judging whether the current drying rate is smaller than a preset critical drying rate or not; and if the current drying rate is smaller than the preset critical drying rate, then generating and sending a stop instruction to turn off microwave and stop drying. The intelligent control method and device are mainly used in the sintered fuel drying process.

Description

technical field [0001] The present application relates to the field of automatic control, in particular to an intelligent control method and device for the drying end point of sintered fuel. Background technique [0002] At high temperature, the solid particles are bonded to each other, the grains grow, and the voids and grain boundaries gradually decrease. Through the transfer of substances, the total volume shrinks and the density increases, and finally becomes a dense polycrystalline sintered with a certain microstructure. body, this phenomenon is called sintering. Microwave is an electromagnetic wave with a wavelength between 1mm and 1m and a frequency ranging from 300MHz to 3000GHz. Microwave heating does not require heat conduction between substances. Microwaves can directly penetrate the entire object, and use its energy dissipation to make all parts of the material gain heat at the same instant and heat up to directly heat the entire material. Such as figure 1 and...
