Automatic contraposition hydraulic cylinder protection device for coke dry quenching

Abstract

The invention relates to a protection device of an automatic aligning hydraulic cylinder used for dry coke. The protection device which comprises two automatic aligning hydraulic cylinders is characterized in that an automatic aligning hydraulic cylinder movement indicating lamp system is arranged and connected with the automatic aligning hydraulic cylinder, and a release delaying program and an interlocking program of the automatic aligning hydraulic cylinder are arranged on a programmable controller. The protection device of the automatic aligning hydraulic cylinder used for the dry coke has simple structure and rational design, and does not require large-scale transformation to a prior automatic aligning system, can realize the protection for the automatic aligning hydraulic cylinder and the driving safety of a coke tank truck, and eliminate the accident of damaging the automatic aligning hydraulic cylinder by the coke tank truck because of the false signal of a magnetic switch, thereby, the maintenance cost and the hot shut down event of the dry coke operation are not existent. The invention can be widely used for the dry coke aligning system widely used in China.

Description

technical field [0001] The invention belongs to dry quenching equipment in the field of coal chemical coking industry, and in particular relates to an automatic alignment hydraulic cylinder protection device for dry quenching coke coke tank car positioning and alignment system. Background technique [0002] Dry coke quenching is to use the heat exchange between the red hot coke block and the inert gas in the dry quenching furnace to cool the coke. The tumbling steam carries dust and other exhaust gas discharge conditions. At the same time, the heated inert gas can transfer heat to the heat exchange surface of the boiler to generate steam, which can be directly used for power generation and realize the comprehensive utilization of resources. Dry coke quenching can recover 80% of the sensible heat of red coke, and can also generate steam that can be further used for power generation, so it is widely used in the current coking industry. [0003] At present, the CDQ device for...

AI Technical Summary

Problems solved by technology

However, the defects of this equipment and device are: after the hydraulic cylinder releases the coke tank car, it cannot return to the original position immediately, but because the hydraulic cylinder is already in the released state, the driver of the coke tank car received the signal that the car can be driven. If the tanker continues to move, it will cause the coke tanker to hit the automatic alignment hydraulic cylinder, causing damage to the locking release mechanism or rupture of the hydraulic oil pipe

This will cause thermal shutdown of CDQ equipment and increase maintenance costs
