Anti-scale steam boiler convenient to clean

Abstract

The invention discloses an anti-scale steam boiler convenient to clean and relates to the technical field of boiler equipment, the anti-scale steam boiler comprises a boiler, a threaded pipe is slidably connected to the center of the upper surface of the boiler in a penetrating mode, a first connecting pipe is fixedly connected to the lower end of the threaded pipe, and a first through hole is formed in the circumferential side face of the first connecting pipe in a penetrating mode; and the lower end of the first through hole is fixedly connected with a second connecting pipe, a first threaded groove is formed in the upper end of the inner wall of the second connecting pipe, scraping rods are fixedly connected to the front side face and the rear side face of the second connecting pipe, through grooves are formed in the side faces of the scraping rods, and second through holes are formed in the lower end of the inner wall of the second connecting pipe and the inner walls, close to the second connecting pipe, of the through grooves in a penetrating mode. The technical problems that an industrial boiler is generally large in size, the interior of a boiler shell cavity is deep, a long tool needs to be used when a filtering device is taken out, meanwhile, the problem that scale falls into a boiler shell due to the fact that the filtering device inclines laterally when the filtering device is taken out is solved, the operation of taking out the scale is tedious, errors are prone to occurring, labor is consumed, and the efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to an anti-scaling steam boiler that is easy to clean. Background technique [0002] Steam boilers can be divided into electric steam boilers, oil-fired steam boilers, gas-fired steam boilers, etc. according to the fuel. Since the water in the steam boiler is mostly tap water or industrial water, there is a lot of scale in the water, and long-term use is likely to cause damage to the inner wall and bottom of the furnace shell. A large amount of scale is accumulated, which is not easy to clean and affects the heating of the boiler. Therefore, a steam boiler that can be easily descaled is required. [0003] For example, according to the "steam boiler with descaling and antiscaling function" provided by the Chinese patent authorization announcement number CN 209325757 U, by setting a filter device in the inner cavity of the furnace shell, the scale entering the inner cavity of...

Problems solved by technology

[0004] The object of the present invention is to provide an easy-to-clean anti-scaling steam boiler, which solves the problem that industrial boilers are generally large in size and deep in the furnace shell cavity. When taking out, the side of the filter device is tilted and the scale falls into the furnace shell. The operation of taking out the scale is cumbersome and prone to mistakes, and the technical problem is that the labor cost is low.
