AI Technical Summary

Technical Problem

In existing pneumatic ash conveying technology, the conveying cycle of multiple silo pumps is relatively long, resulting in low ash conveying efficiency. Furthermore, as the number of silo pumps increases, the conveying cycle also increases.

Method used

By determining the polling ash conveying sequence of N silo pumps, the first silo pump currently conveying ash is identified, and while it is conveying ash, the second silo pump, which is separated by a preset sequence interval, is controlled to perform feeding operations, thereby reducing waiting time and improving ash conveying efficiency.

Benefits of technology

By controlling the feeding of the second silo pump in parallel, the cycle of pneumatic ash conveying was significantly shortened, the ash conveying efficiency was improved, and the increase in the ash conveying cycle caused by the increase in the number of silo pumps was reduced.

Abstract

The application discloses a kind of pneumatic ash conveying control method and pneumatic ash conveying device, it is related to pneumatic ash conveying field, because same ash pipe simultaneously only allows one bin pump to carry out ash conveying to ash storehouse, so it needs to confirm the sequence of N bin pumps for polling ash conveying first.And other bin pumps are in waiting after the last bin pump completes ash conveying operation to carry out feeding operation, so only need to determine the first bin pump for carrying out ash conveying operation after determining the polling ash conveying sequence of N bin pumps, and determine the second bin pump separated from the first bin pump by preset sequence interval according to the polling ash conveying sequence, finally control the second bin pump to feed.In because the time of feeding is greater than the time of ash conveying, while the first bin pump is conveying ash, the second bin pump is controlled in parallel to feed, save time, greatly shorten the cycle of pneumatic ash conveying, improve the efficiency of pneumatic ash conveying.
