Description

Technical Field

[0001] The utility model relates to the technical field of tamping machines, in particular to an intelligent multi-hammer hydraulic tamping machine. Background Art

[0002] The tamping machine is an important equipment in coke oven machinery. It uses the tamping equipment outside the coke oven to pound the coking coal into briquettes slightly smaller than the carbonization chamber according to the size of the carbonization chamber. The briquettes are pushed into the carbonization chamber from the side of the carbonization chamber for high-temperature distillation. The mature coke is pushed out of the carbonization chamber by the tamping and pushing machine, and sent to the quenching tower by the coke intercepting car and the coke quenching car. After being quenched with water, it is placed on the coke cooling platform and transported by belt conveyor to be classified into commercial coke of different particle sizes through coke screening.

[0003] The following problems are prone to occur when using existing tamping machine equipment. First, the tamping equipment in the tamping machine is fixed, and it cannot tamp the coal powder at different positions in the coal box. The working area is small and the tamping efficiency is low. Second, different types of coal will be tamped during production, but the tamping power of the existing tamping machine is fixed, which leads to the coal cake density of some types of coal not meeting the standard, poor stability, easy collapse, and reduced coke quality. Third, the tamping hammers are mostly connected by bolts and nuts, but the bolts are very easy to loosen during the frequent vibration of the tamping hammer, increasing the safety hazards of the use of the tamping hammer. Therefore, in response to the above problems, we proposed an intelligent multi-hammer hydraulic tamping machine. Utility Model Content
