AI Technical Summary

Technical Problem

The flow rate during the dry ash feeding process in existing power plants is unstable and difficult to control precisely. Furthermore, the drop height causes dust pollution, which endangers health and violates environmental protection requirements.

Method used

A control device was designed, including a transmission chamber, a diversion shell, a feeding hopper, and a telescopic assembly. The dry ash flow rate is controlled by a transmission auger and a motor. The height and flow rate of the discharge port are adjusted by the telescopic assembly and a manual control valve to avoid splashing and backflow.

Benefits of technology

It achieves stable control of dry ash flow rate, reduces dust, improves loading efficiency, adapts to ash transport vehicles of different heights, and avoids environmental pollution and health hazards.

Abstract

This utility model discloses a control device for controlling the flow rate of dry ash in power plants, specifically relating to the field of dry ash treatment technology in power plants. It includes an ash hopper, with a transmission chamber connected to the bottom of the ash hopper. A control switch is installed on the outer wall of the transmission chamber, and several diversion shells are connected to the bottom of the transmission chamber. Each diversion shell has a control valve installed on its top, and a main discharge shell is connected to the bottom of the transmission chamber's end. By setting up the transmission chamber and multiple diversion shells, this utility model can control the outflow of dry ash as needed during use, allowing the dry ash to flow out of the ash hopper faster or slower. Furthermore, by setting up a telescopic component, the extension and retraction can be adjusted using the hooks on the locking mechanism of the telescopic component. This facilitates adjustment of the height of the discharge port at the bottom of the discharge shell as needed during use, thereby allowing for adjustment and use on ash transport vehicles of different heights, improving applicability, and avoiding the problem of dry ash being blown up due to height differences.
