AI Technical Summary

Technical Problem

In the original pneumatic ash conveying device, the pipelines and elbows are densely distributed, resulting in increased resistance during the ash conveying process, which is prone to leakage and blockage, which reduces the conveying efficiency and system stability. At the same time, the air system pressure is maintained at a low level, resulting in greater energy consumption.

Method used

A pneumatic ash conveying device distributed in multiple pipe segments is designed, using multiple bin pumps and timers to combine anti-wear ceramic lining materials and wear-resistant spherical elbows to achieve uniform dust conveying and anti-wear performance of the pipeline.

Benefits of technology

Through multi-pipe section distribution and precise control, uniform dust transport is achieved, transportation efficiency is improved, energy consumption and maintenance costs are reduced, and system stability and safety is enhanced.

Abstract

The utility model relates to the technical field of pneumatic ash conveying devices, and discloses a multi-pipe-section distributed pneumatic ash conveying device which comprises an ash silo, a first mother pipe and a second mother pipe are arranged on the top of the ash silo in a communicated mode, the bend positions of the first mother pipe and the second mother pipe are connected through an elbow, and a first bin pump, a second bin pump and a third bin pump are arranged below the first mother pipe respectively. A fourth bin pump, a fifth bin pump and a sixth bin pump are arranged below the second main pipe, the input ends of the first bin pump, the second bin pump, the third bin pump, the fourth bin pump, the fifth bin pump and the sixth bin pump are all connected with feeding pipes, the output ends of the first bin pump, the second bin pump, the third bin pump, the fourth bin pump, the fifth bin pump and the sixth bin pump are all connected with discharging pipes, and the discharging pipes communicate with the first main pipe and the second main pipe. A novel anti-abrasion ceramic lining material is adopted on a conveying pipeline, high-speed abrasion of the material to equipment is reduced, resistance of a system pipeline and an elbow is reduced, the abrasion resistance of the whole pipeline is improved, the consumption of compressed air is reduced, and the abrasion resistance of a pipeline system is improved while efficient ash conveying is achieved.
