Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cement storage and delivery system, in particular to a cement delivery system with multiple stable functions. BACKGROUND
[0002] The cement storage used in the new dry process cement production line is mainly a cylindrical concrete storage. The cylindrical concrete storage has the characteristics of simple structure, high utilization rate and flexible layout, and its structural forms include conical hopper, conical pressure reducing bin with air charging box, IBAU storage, etc. The air charging unloading device powered by a Roots blower is often arranged at the bottom of the storage for discharging, and the unloading equipment adopts pneumatic on-off valve and electric flow control valve.
[0003] In recent years, due to the demand for controlling the quality of cement, the CF storage originally commonly used for raw material homogenization storage is also increasingly applied to cement storage. Compared with the traditional cement storage, the CF storage has a higher homogenization ratio (up to 10-16), which can effectively ensure the quality requirements of the cement leaving the factory. The bottom of the CF storage is divided into seven equal-sized regular hexagonal unloading areas, each of which is composed of six triangular air charging areas and an unloading port. The air charging at the bottom is supplied by a Roots blower, and the opening time and sequence of the valves on the air supply pipeline and the valves on the unloading slots are controlled by a programmable controller, so that the materials in each triangular area at the bottom are discharged at different speeds and finally mixed into a buffer bin with a diameter of about 1 meter. The materials are discharged from the buffer bin to an air chute and then transported to the cement packaging and bulk loading workshops. In actual production, the unloading time and amount of each unloading device can be adjusted to achieve the best unloading distribution effect.
[0004] However, when the CF storage is used as a cement storage, the materials discharged from the storage mostly enter separate packaging or bulk loading workshops, the buffer bin is too small, and the system function is relatively single. Moreover, the problems of high cost of civil engineering and equipment, complex system for controlling homogenization and unloading, etc. still exist. Therefore, in order to promote the industry technology, better optimize the cement delivery process, control the cost as a whole, and improve the core technical competitiveness, the present application proposes a new implementation scheme different from the cement delivery system and application mode in the prior art.
