Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, a method for controlling a dust-settling and deodorizing device for a discharge opening includes the following steps;
s1, setting parameters: an operator sets a pressure value required by the high-pressure electromagnetic valve for spraying and drying and the delay time of the garbage truck during unloading through the touch screen;
s2, controlling the operation of a booster pump: the starting and stopping of the booster pump are controlled by the PLC according to the set pressure value and the deodorant storage tank liquid level meter, and the pressure in a pressure stabilizing tank connected with the booster pump can be kept stable when the booster pump runs;
s3, discharging: when unloading is to be carried out, a laser correlation photoelectric switch signal is detected, the garbage truck enters a berth, unloading is started, the PLC delays to open the high-pressure electromagnetic valve through the delay time set on the touch screen, and meanwhile, the booster pump extracts the deodorant in the liquid storage tank and sprays the deodorant in the unloading process;
s4, calculating the dosage of the deodorant: when the vehicle leaves, the PLC controls to close the high-pressure electromagnetic valve and automatically calculates the dosage of the deodorant sprayed during discharging;
