[0002] The boiler slag removal structure is a core auxiliary system of the boiler, mainly used in industrial boilers in thermal power, metallurgy, chemical and other industries. Its core function is to remove the slag produced by boiler combustion in a timely manner, and at the same time complete the slag cooling, transportation and solid-liquid separation to avoid slag accumulation affecting boiler combustion efficiency or causing safety hazards.

[0003] In existing boiler ash removal structures, the spiral blades and shaft of the spiral rod are an integral structure. If a section of the blades is worn, corroded, or deformed due to insufficient wear resistance, it is impossible to replace the damaged part individually, and the entire part must be scrapped and replaced. To address this issue, this utility model proposes a boiler ash removal structure. Utility Model Content

[0004] The purpose of this utility model is to provide a boiler slag removal structure to solve the problem that the spiral rod of the boiler slag removal structure mentioned in the background art is an integral structure, which requires the entire structure to be replaced when there is partial damage.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 5This utility model provides a technical solution: a boiler slag removal structure, including a conveying structure 2 disposed inside a shell 1. The shell 1 is the outer casing of the equipment, serving to accommodate slag and support internal components; forming a closed conveying space to prevent slag leakage and protect the internal conveying structure from external environmental interference. The conveying structure 2 consists of a conveying component A21, a conveying component B22, and a connecting component 23. The conveying structure 2 is the core component for realizing slag conveying. The conveying component A21 consists of a spiral shaft A211 and blades A212, with blades A212 sleeved and fixed to the surface of the spiral shaft A211. The conveying component B22 consists of a spiral shaft B221 and blades B222, with blades B222 sleeved and fixed to the surface of the spiral shaft A211. The connecting assembly 23 is located on the surface of the screw shaft B221, with the end of the screw shaft A211 and the end of the screw shaft B221 in a fitted state. The connecting assembly 23 is positioned at the fitted point between the ends of the screw shaft A211 and the screw shaft B221. The designed conveying structure 2 is a split structure, allowing for independent manufacturing in sections. If a section of the blade is worn, corroded, or deformed, only the damaged section needs to be replaced, eliminating the need to scrap the entire screw shaft. This avoids the entire screw shaft becoming unusable due to localized damage, thus preventing resource waste. The ends of blade A212 and blade B222 are in a fitted state. The connecting assembly 23 consists of multiple positioning components 231 and a preliminary installation component 232. The preliminary installation component 232 consists of a screw groove 2321 and a screw... The spiral column 2322 is composed of a spiral groove 2321 at the end of the spiral shaft B221. The spiral column 2322 is fixed to the end of the spiral shaft A211, and the spiral column 2322 and the spiral groove 2321 are threaded together. Multiple positioning components 231 are disposed on the end surfaces of the spiral shaft A211 and the end surfaces of the spiral shaft B221. Each positioning component 231 consists of a positioning crossbar 2311 and symmetrically arranged fixing components 2312. One end of the positioning crossbar 2311 is fixed to the surface of the spiral shaft A211, and the other end of the positioning crossbar 2311 is in contact with the surface of the spiral shaft B221. The symmetrically arranged fixing components 2312 consist of bolts and mounting holes, all of which are formed on the surface of the spiral groove 2321. On the inner side of the initial installation component 232, bolts pass through the inner side of the installation holes. A slag inlet is provided on one end surface of the housing 1, which communicates with the inner side of the housing 1. A drive component 3 is provided on the surface of the housing 1. The drive component 3 consists of a motor, a reducer, and a coupling. After the motor is powered on, the internal rotor rotates and outputs an initial speed and torque. The motor power is transmitted to the reducer. Through the meshing transmission of gears or worm gears, the high speed and low torque are converted into low speed and high torque to meet the power requirements of the screw shaft to push the slag. The power processed by the reducer is transmitted to the conveying structure 2 through the coupling to realize the continuous pushing of the slag and complete the slag cleaning and conveying process. A slag outlet is provided at the bottom of the other end of the housing 1.

[0016] The working principle and usage process of this utility model: During the boiler slag cleaning process, the slag produced by boiler combustion is discharged from the boiler slag discharge port and first enters the feed port of the slag cleaning equipment. Then, the conveying structure 2 rotates under the drive of the drive component 3, continuously pushing the slag along the inside of the shell 1. During the pushing process, the slag is conveyed and initially crushed. Finally, the slag is discharged from the slag outlet at the other end of the shell 1 and enters the subsequent crushing or external transportation stage to complete the slag cleaning. During the disassembly of conveying structure 2, which consists of conveying component A21, conveying component B22, and connecting component 23, the disassembly must follow these steps: Stop the operation of drive component 3, disconnect the power supply to the equipment, ensure operational safety, and then remove connection component 23. First, operate positioning component 231, loosen fixing component 2312, and release the positioning constraints of conveying component A21 and conveying component B22. Then, operate preliminary installation component 232. By rotating conveying component A21 or conveying component B22, the spiral groove 2321 and spiral column 2322 between spiral shaft A211 and spiral shaft B221 are separated. Then, the conveying component A21 or conveying component B22 can be pulled out.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
