Heat supply system of biomass boiler

Abstract

The invention discloses a heat supply system of a biomass boiler. A high-position soft water pool supplies water to the boiler, a boiler body is provided with a hot water outlet pipe connected to rooms, and a high-temperature tail gas pipe of the boiler body is connected to an air induction fan; valves are arranged in the rooms for controlling hot water bathing, solenoid valves are additionally arranged and are linked to fan coils for working, and a water return pipe gathers flow and returns; a coupling and a fan shaft of the air induction fan are assembled in a threaded mode, a fan impeller and the fan shaft of the air induction fan are assembled in a threaded mode, and the thread rotation direction is the automatic locking direction along with working and bearing; the fan impeller is in threaded and rigid connection with the fan shaft after pressing a copper-lead torsion composite pad; the coupling and the other end of the fan shaft are connected rigidly through a clamp part. According to the system, heat recovery and purification treatment of tail gas of the boiler are realized, the disassembly and assembly technology of the air induction fan of the boiler is greatly modified, the problems that the air induction fan of the boiler is continuously and automatically locked and is difficult to disassemble under the loading effect due to threaded assembly can be effectively solved, and large boiler fans can be disassembled conveniently and quickly after being locked in a threaded mode.

Description

Technical field [0001] The invention relates to a biomass boiler heating system which is convenient for disassembly and maintenance of an induced draft fan. Background technique [0002] Biomass boiler heating systems mainly use biomass such as corn stalks as fuels. Biomass fuels are widely available in rural areas and are easily available. However, due to various restrictions on rural heating in my country, it is always difficult to solve. Therefore, the development of biomass boiler heating systems is An important way to solve the problem of rural heating. [0003] The boiler is the main equipment of the biomass boiler heating system. Both air supply and dust removal of the boiler cannot be separated from the long-term operation of the fan. Therefore, the fan is the key equipment of the boiler. The larger the tonnage of the boiler, the larger the fan used. , The structure of ordinary fans is generally that one end of the fan shaft is the fan impeller, and the other end is the mot...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
