Embodiment Construction
[0027] Embodiments of the present invention will be described below in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, a method for controlling loading and unloading of a rotary kiln comprises the following steps:
[0029] 101. At the raw material inlet and clinker outlet of the rotary kiln, wind pressure negative pressure gauges for measuring the wind pressure at the raw material inlet and clinker outlet are respectively installed, and a discharge gate is installed at the clinker outlet of the rotary kiln, with a display The upper computer of the screen is connected with the rotary kiln, the discharge ram and the alarm device.
[0030] The upper computer is connected with the rotary kiln, and controls the start and stop of the feeding system of the rotary kiln at the same time, and collects the pressure value of the air pressure negative pressure gauge, and the monitoring screen in the rotary kiln is also displayed on the display screen of the...

The invention discloses a feeding and discharging control method of a rotary kiln. By optimizing programs and adding equipment interlocking points, possible faults are judged in advance, staff on post are warned or protective measures are taken automatically, and the situation that material blocking occurs inside the rotary kiln, and consequently the production efficiency is affected is prevented. The method includes the steps that (1) negative air pressure meters are mounted at an inlet and an outlet of the rotary kiln, a blanking gate board is mounted at the outlet, and an upper computer is connected with the rotary kiln, the blanking gate board and an alarm device; (2) feeding is started, timekeeping is performed, the position of a material head is judged, and after materials are full fed and both the inlet air pressure and the outlet air pressure are detected to be within the range of preset values, material discharging is started from the outlet; and (3) feeding is stopped, the position of a material tail is judged according to timekeeping and the rotating speed of the rotary kiln and feeding is stopped, and after feeding is stopped for a preset time, discharging is finished.
Description
technical field [0001] The invention belongs to the field of gypsum board production, and in particular relates to a method for controlling loading and unloading of a rotary kiln. Background technique [0002] In the production of gypsum board, the rotary kiln of the pulverizing system is the key equipment of the clinker system. There are many steam pipes inside the kiln. The raw gypsum completes heat exchange with the steam during the movement, loses moisture and becomes mature gypsum. In the actual production process, due to the high temperature of the steam pipe and the long-term heavy load inside the rotary kiln, the steam pipe is easily deformed, resulting in material blockage inside the rotary kiln and difficult cleaning. Contents of the invention [0003] The object of the present invention is to provide a method for controlling loading and unloading of a rotary kiln, which can prevent the above problems generated in the production process of the rotary kiln from af...
