Electrode Boiler Heating Electrode Rod Device

Abstract

The invention discloses an electrode boiler heating electrode rod device which comprises a conductive rod and an insulating sleeve. The conductive rod is arranged in the insulating sleeve, the electrode boiler heating electrode rod device also comprises an electrode head, the electrode head is a solid-core electrode head, and the electrode head is directly or indirectly fixedly connected with theconductive rod. The electrode boiler heating electrode rod device has the following beneficial effects that the solid-core electrode head is adopted as the electrode head, no space exists in the electrode head, no residual substance is accumulated in the electrode head, and stable operation parameters of an electric boiler during operation are guaranteed; and meanwhile, grooves are formed in the outer wall surface of the electrode head, so that the contact area between the electrode head and water is enlarged, the resistance between the electrode head and water is increased, the surface current of the electrode head is reduced, and the safety factor of the electrode head is increased.

Description

technical field [0001] The invention relates to the field of electrode boilers, in particular to an electrode boiler heating electrode rod device. Background technique [0002] Now the amount of electric boilers is increasing, and the electrode is a very critical part of the electric boiler. Patent CN2016100342402 provides a new type of submerged heating electrode. There is a round hole (number 4 in the reference number) at the lower bottom, but this will cause water in the boiler to enter the body from the round hole, and as long as the electric boiler is in the working process state, the body of the electrode is always immersed in water In this way, the water inside the body is "dead water". When the boiler is used to drain the water, there will be water inside and outside the body, and the dissolved substances in the water will precipitate on the inner and outer walls of the body. When people wash it, they can only wash away the precipitated substances on the outer wall ...

[0002] Now the amount of electric boilers is increasing, and the electrode is a very critical part of the electric boiler. Patent CN2016100342402 provides a new type of submerged heating electrode. There is a round hole (number 4 in the reference number) at the lower bottom, but this will cause water in the boiler to enter the body from the round hole, and as long as the electric boiler is in the working process state, the body of the electrode is always immersed in water In this way, the water inside the body is "dead water". When the boiler is used to drain the water, there will be water inside and outside the body, and the dissolved substances in the water will precipitate on the inner and outer walls of the body. When people wash it, they can only wash away the precipitated substances on the outer wall of the body, but the substances precipitated on the inner wall of the body cannot be washed away

[0003] Because the water used in the use of the electric boiler is not pure water, but water with a certain amount of electrolyte dissolved in it, and the electrolyte used in each use of the electric boiler is not fixed, it is determined according to the specific use requirements, such as this Electrolyte A is used for the first time, and electrolyte B is likely to be used next time, so there is a problem. Assuming that this use is the first time the electric boiler is completed, after the use is completed, electrolyte will be deposited on the inner wall of the body. A. When electrolyte B is used for the second time, the electrolyte A attached to the inner wall of the body will be redissolved in the water, and this will cause the electrolyte in the water in the actual boiler to change, resulting in unstable operating parameters of the electric boiler
