Abstract

The present invention provides a method and system for simulating the movement state of bricks in a kiln. The method for simulating the movement state of bricks in a kiln comprises the steps: dividing a kiln into a plurality of areas on the basis of variable frequency drives; calculating a cycle time required for bricks to pass through each area; on the basis of the actual number of kiln sections in each area, using a corresponding number of bytes to simulate the area; calculating a refresh time on the basis of the cycle time and the number of bytes; setting marks at character bits of each byte to simulate the current position of the bricks in the area; and on the basis of the refresh time and the number of character bits, updating the positions of the marks in the bytes to simulate the movement state of the bricks in the roller kiln. According to the present invention, the position of bricks in a kiln can be simulated, an operator can directly observe the current accurate position of the bricks, and after the operator knows the accurate position of the bricks, the operator can be guided to carry out proper intervention and temperature control, thereby improving the automation level of the system, reducing manual intervention, and improving the production efficiency.

Abstract

The present invention belongs to the field of ceramic sintering apparatuses. Disclosed are an intelligent temperature control system and method for a ceramic kiln. The intelligent temperature control system for a ceramic kiln comprises a heating device, a cooling device and a temperature control device. In the intelligent temperature control method for a ceramic kiln, by means of comparing upper and lower limit critical points of temperature with set values to expand the temperature sensing range, it is determined whether to open or close an igniter and a gas valve, so that the igniter and the gas valve will not be frequently opened and closed when the temperature reaches the upper or lower limit critical point or when the temperature fluctuates greatly, thereby prolonging the service life of equipment, and the amplitude of temperature change in the ceramic kiln is small, thereby improving the product quality and reducing the gas consumption.
