Its main function is: scraping the powder coke from the quenching water sedimentation tank to the storage pool. According the PROFIBUS-DP fieldbus technology to complete the Data communication between PLC and running, scraper lifting inverter and encoder, laser level gauge and other components. The data communication and the control program developed in combination with the process realize the precise control of the locomotive running and scraping speed, displacement and running direction. Monitor the production status from the set workstation.
The technology can be extended to other technical fields of material collection, classification, transfer and transportation with similar physical and chemical characteristics of powder coke.
1 process design
Two powder coke collecting and water filtering joint tanks are designed at the end of the quenching pump room of the coke oven system, and a filtering device is designed between the powder coke collecting pool and the pump pool. The bottom elevation of the powder coke collecting pool is higher than the bottom level of the filtering tank. With a difference of 2.5 m, a quenching canal is designed on the side of the second tank, which is connected to the quenching tower. The exit of the quenching tower water channel is designed with a fan-shaped gate. There is a quenching water inlet at the relevant position of the powder coke collecting tank. There are several outlets for filtered water at the bottom of the filter tank. The outlet is the same as the quenching water channel, and the filtered water is directly Return to the powder coke pool, the purpose is to achieve the recycling of quenching water and powder coke water.
Between the powder coke collection tank and the filter water connection tank is designed as a slope, and the automatic powder coke processing equipment is arranged on each of the two pools to realize one for use and one for preparation.
2 work program design
The main function of the automatic powder coke collecting device: the machine is to scrape the powder coke from the quenching water sedimentation tank to the storage pool, and at the same time complete the smoothing and effective stacking of the powder coke in the storage pool. The main working procedures are based on the running mechanism, scraper lifting mechanism, frequency converter, signal detection component, PLC control system, and control software to achieve automatic material collection and material leveling, to achieve unmanned operation and monitoring. At the same time, the effective volume of the storage tank is fully increased.
