Abstract

The invention relates to a rotary kiln catch wheel hydraulic system and a working method thereof. The system comprises an oil tank A, a gear pump, a first one-way valve, a first pressure switch, a first electromagnetic directional valve, a first one-way throttle valve, a second one-way throttle valve, a second pressure switch, a second one-way valve, a third one-way valve, a first filter, an overflow valve, a second filter, a third pressure switch, a fourth one-way valve, an oil tank B, a small-flow high-pressure pump, a catch wheel oil cylinder, a fifth one-way valve and a second electromagnetic directional valve. The rotary kiln catch wheel hydraulic system and the working method thereof aim to shorten the oil supplementing time of the catch wheel hydraulic system, and the adjusting result of the throttle valves is not damaged in the oil supplementing process; and in addition, the hydraulic system is used for monitoring the stress state of a rotary kiln during running, key components of the rotary kiln are effectively protected, and the service life of the rotary kiln is prolonged.

Description

technical field [0001] The invention relates to the technical field of rotary kiln, in particular to a rotary kiln retaining wheel hydraulic system and a working method thereof capable of realizing fast refueling and safety protection functions. Background technique [0002] The rotary kiln is a widely used thermal kiln. Its working principle is: through the motor and transmission device, the cylinder is driven to roll continuously on the supporting wheel, so that the material moves from the high end to the low end of the rotary kiln. If the relative position of the rolling ring and the supporting wheel of the rotary kiln remains unchanged, grooves will be formed on the supporting wheel due to wear, which will affect the operation of the rotary kiln and increase the rotational resistance. [0003] Large-scale rotary kilns are generally equipped with a retaining wheel to cooperate with the thrust wheel to push the wheel to move up and down on the supporting wheel, so as to av...
