Taking-out back water reciprocating flue type boiler

Abstract

The invention belongs to an extraction back-water reciprocating flue-type boiler. The boiler is divided into two parts of an upper boiler body and a lower boiler body; the upper boiler body, the lower boiler body and an extraction type water inner are independently arranged and combined into a whole body by assembly; the upper boiler body at the lower end of a water storage tank is the water inner of the upper boiler body; the lower boiler body is positioned at the lower end of the upper boiler body; the upper part of the lower boiler body is provided with an extraction slot which is used for being placed or extracted by the extraction type water inner; the extraction type water inner is positioned in the extraction slot; an uplink flue is spiral, the lower end of the uplink flue communicates with the upper end of the extraction slot, and the lower end of the extraction slot communicates with a boiler chamber. The extraction back-water reciprocating flue-type boiler of the invention adopts the separated independent production and the assembly combination, increases the area of the uplink flue in a water jacket to fully absorb the heat of the boiler body and further has the extraction type water inner structure, which can rapidly replace the structure of a water pipe in the high-temperature area that is positioned at the upper end of the boiler chamber, thus having the advantages of simple structure, low production cost, fast fire ignition, good safety, high thermal utilization ratio and long service life.

Description

technical field [0001] The invention belongs to a reciprocating flue boiler with extraction and backwater. Background technique [0002] Most of the traditional heating boilers adopt an integrated structure, which is to set interlayers on the side and top of the furnace body to form a water-absorbing tank. The water inlet pipe is connected to the lower end of the water-absorbing pipe, and the outlet pipe is connected to the upper end of the water-absorbing pipe. The cold water enters the water-absorbing pipe and the water-absorbing pipe from the water-inlet pipe. The water inside becomes hot water, and is discharged from the furnace body through the water outlet pipe at the upper end of the water-absorbing water tank. This traditional heating boiler uses cold water to enter the water-absorbing tank near the furnace at the lower end of the furnace body, then gradually heats up, absorbs heat and turns it into hot water, and then flows out of the furnace body through the outle...
