Boiler with water scale removing function

Abstract

The invention relates to a boiler with a water scale removing function. The boiler comprises a cylindrical boiler body, the boiler body is vertically arranged, a cleaning mechanism is arranged in the boiler body, a collecting mechanism is arranged at the bottom of the boiler body, and the cleaning mechanism comprises a cleaning ring, a rotating assembly and a lifting assembly. The rotating assembly comprises a connecting bearing, a rotating shaft, a ball screw pair, a floating disc and two fixing rods, the collecting mechanism comprises a fixing pipe, a sealing plate, a filter screen, a driving shaft, a one-way bearing, a paddle, a fixing ring, a sealing disc, two guide pipes and two transmission assemblies, and a mounting hole is formed at the bottom of the boiler body. The fixing pipe, the driving shaft, the fixing ring and the sealing disc are all coaxial with the rotating shaft. According to the boiler with the water scale removing function, the water scale removing function is achieved through the cleaning mechanism, and in addition, the function of collecting impurities in water is achieved through the collecting mechanism.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a boiler with scale removal function. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. [0003] In the process of heating water in the existing boiler, there will be impurities in the water, and the impurities will increase the anion and cation in the water, increase the salt content, accelerate the corrosion rate of the boiler, and cause the boiler water to foam and deteriorate the steam quality Not only that, after long-term use of the filter, more scale will be generated on the inner wall, and the scale will deteriorate the heat transfer performance of the heating surface, and the heat released by fuel combustion cannot be transferred to the pot water i...

[0003] In the process of heating water in the existing boiler, there will be impurities in the water, and the impurities will increase the anion and cation in the water, increase the salt content, accelerate the corrosion rate of the boiler, and cause the boiler water to foam and deteriorate the steam quality Not only that, after long-term use of the filter, more scale will be generated on the inner wall, and the scale will deteriorate the heat transfer performance of the heating surface, and the heat released by fuel combustion cannot be transferred to the pot water in time, and a large amount of heat will be carried by the flue gas. If the exhaust gas temperature is too high, the loss of exhaust gas will increase, and the thermal efficiency of the boiler will decrease.
