AI Technical Summary
The existing exhaust heating system of mining dump trucks cannot dynamically adjust the heating intensity according to the type of loaded material, which leads to excessively high material temperature triggering temperature alarms during coal hauling or insufficient heating in frozen and sticky conditions, causing difficulties in unloading and equipment damage.
It adopts an exhaust gas diversion unit, a zone heating unit, and a temperature detection unit, combined with an intelligent control unit, to achieve multi-mode intelligent control. It automatically adjusts the heating zone and intensity according to the material type, and performs closed-loop regulation through a PID control algorithm to ensure that the material temperature is within a safe range.
It effectively controls material temperature, avoids over-temperature alarms in the crusher, and provides strong heating in the case of freezing and sticking to prevent freezing and sticking. It maintains the zero-energy advantage of exhaust gas waste heat utilization and realizes the intelligent adaptive operation of the dump truck heating system.
