AI Technical Summary

Technical Problem

When the existing boiler anti-clogging return material device is in use, the material tends to accumulate at the bottom of the return material box as it passes through, causing blockage and reducing return efficiency. Furthermore, ash and slag in the flue gas tend to accumulate on the inner wall of the return material box, further increasing the risk of blockage.

Method used

A boiler anti-clogging return material device was designed. By setting up an anti-clogging component and an inclined tube, and utilizing a power component to drive a rotating push plate and scraper, the device addresses the technical problem of material accumulation at the bottom of the return material box. The device also addresses the issue of material accumulation by using a blower and air blowing pipe assembly to pump ash and other materials into the incinerator.

Benefits of technology

It effectively prevents the accumulation and blockage of materials and ash in the return box, improves the smoothness and efficiency of return, reduces the frequency of equipment cleaning, and improves the service life and operating efficiency of the equipment.

Abstract

This utility model discloses a boiler anti-clogging return material device, which relates to the field of boiler return material and ash discharge technology. Its structure includes a base, with an incinerator fixedly connected to one side of the top of the base. A feeding pipe is fixedly connected to one side of the incinerator, and a feeding funnel is fixedly connected to the top of the feeding pipe. A return material pipe is connected to the top of the other side of the incinerator, and a return material box is fixedly connected to the bottom of the return material pipe. An inclined pipe is fixedly connected between one side of the return material box and the surface of the incinerator. This boiler anti-clogging return material device can prevent the returned material and long-term accumulated ash from clogging the return material box, improving the return material efficiency of the device. Simultaneously, blowing air into the inclined pipe can accelerate the conveying of materials inside the inclined pipe, further improving the return material effect and efficiency of the device.
