Abstract

The invention provides a coke pushing system for a dry distillation furnace. The coke pushing system comprises a hydraulic power mechanism, a hydraulic cylinder and a coke pushing trolley; the hydraulic power mechanism is used for supplying hydraulic oil to the hydraulic cylinder so as to drive a piston rod of the hydraulic cylinder to move linearly in a reciprocating mode; and one end of the piston rod of the hydraulic cylinder is connected with the coke pushing trolley for driving the coke pushing trolley to make linear reciprocating motion. According to the coke pushing system for the dry distillation furnace, in the moving process of the coke pushing trolley, force borne by the coke pushing trolley is acting force with the direction being the same as the moving direction of the coke pushing trolley, no upward or downward acting force is applied, and the problem that the coke pushing system is prone to breaking down or prone to being damaged in the prior art can be avoided. Comparedwith the prior art, the coke pushing system for the dry distillation furnace is higher in reliability and is not liable to be damaged; and moreover, structures such as an eccentric wheel are omitted,thus self-locking performance and structural seismic resistance can be improved, and meanwhile, the problem that blind points occur and consequently, and a coke pusher is shut down can be further avoided.

Description

technical field [0001] The invention relates to the field of coal pyrolysis and upgrading, in particular to a coke pushing system for a dry distillation furnace. Background technique [0002] Pyrolysis upgrading of low-rank coal is an important way to effectively develop and utilize low-rank coal, which can realize deep utilization of coal and avoid waste of resources. At present, carbonization furnaces are generally used for pyrolysis and upgrading of coal. [0003] The coke discharge system of the existing retort furnace is generally an eccentric wheel type coke pusher. It mainly includes structures such as frequency conversion motor, eccentric wheel, guide rail and coke pushing trolley; among them, the output end of the frequency conversion motor is connected with the eccentric wheel to drive the eccentric wheel to rotate; the eccentric wheel and the coke pushing trolley are connected through a connecting rod, And between the connecting rod and the eccentric wheel, as w...
