Hot water auxiliary system for natatorium

Abstract

The invention discloses a hot water auxiliary system for a natatorium. A tail gas tube of a boiler body is emptied through a chimney after being subjected to heat exchange through a tubular heat exchanger, the upper part of the shell side of the tubular heat exchanger is connected to a water supplementation control valve, and the lower part of the shell side feeds water to a boiler through a tube; hot water of the boiler is supplied to bathing through a hot water storage tank, water return tubes enter the boiler after being merged, and therefore heating circulation is realized; water in a swimming pool is conveyed into a coil tube in the hot water storage tank by a circulating water pump and exchanges heat with the hot bathing water, and the heated warm water returns to the swimming pool; a coupling and a water pump shaft of the circulating water pump are assembled in a threaded mode, a water pump impeller and the water pump shaft of the circulating water pump are assembled in a threaded mode, the thread rotation direction is the automatic locking direction along with working and bearing, and rigid connection is realized. According to the system, the single boiler is used for supplying heat to the bathing water and the pool water simultaneously in a constant-temperature mode, the disassembly and assembly technology of the water pump is greatly modified, the problems that the water pump is continuously and automatically locked and is difficult to disassemble under the loading effect due to threaded assembly can be effectively solved, and large water pumps can be disassembled conveniently and quickly after being locked in a threaded mode.

Description

technical field [0001] The invention relates to a hot water auxiliary system of a natatorium with a circulating water pump which is convenient for disassembly and maintenance. Background technique [0002] Swimming is a sport with better fitness effects. If the swimming pool is to be open to the public all year round, it is essential to heat the swimming pool. The heating of the swimming pool includes constant temperature heating for pool water and heating for bathing water. , and heating, etc., because the swimming pool has a large heat supply, so there is also a lot of room for energy saving and emission reduction. [0003] Because the biomass fuel used in the biomass boiler is renewable, and the tail gas has low toxicity, easy natural degradation, and low pollution, it can also be used in densely populated residential areas, and can be used as a heat source for swimming and heating. Good heat recovery and dust removal for biomass boilers are of great significance for ene...

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
