Vertical electrode hot water boiler device

Abstract

The invention discloses a vertical electrode hot water boiler device. The device is characterized in that a three-petal-shaped opening is formed in the middle of an insulation shell and serves as a water guide opening, and the insulation shell is provided with three heating spaces with the inner sides communicated; three electrode plates are bent rectangular plates and are used for being attached to the inner side wall of an electrode supporting plate; a movable shield central pipe is connected with three shield plates which are in a rectangular plate shape, form an included angle of 120 degrees and are used for isolating the electrode plates; and the upper end of a lead screw which penetrates through a nut coaxially arranged with the central pipe and is in threaded fit with the nut penetrates out of a large tank and is connected with a stepping motor. The problem that the electrode structure is unstable is solved through a new structural form, and a zero electrode is omitted; by optimizing the electrode design, the total height of equipment is reduced, the size is reduced, and the applicability of the equipment is improved; the problem of electrification of a tank body is solved, the safety of the equipment is improved, and the equipment cost is reduced; the installation difficulty of internal parts is reduced, the installation cost is saved, and the quality assurance capability is improved; and by optimizing the sealing structure, the sealing reliability is improved.

Description

technical field [0001] The invention relates to an electrode hot water boiler device. Background technique [0002] The main body of the existing vertical electrode hot water boiler device is a large tank, and a manhole is opened on one side of the tank body, so as to install internal parts and maintenance equipment. Electrodes in the shape of three-phase small jars are symmetrically distributed in the tank, and each electrode corresponds to its own cylindrical zero electrode. A triangular connecting plate is used between each zero electrode to realize circuit conduction and achieve the purpose of zero potential. The zero electrode is directly fixed in the tank through the connecting plate. A movable shield of insulating material is arranged between each electrode and the corresponding zero electrode. Each movable shield is fixed on the traction shaft through the traction frame. The traction shaft is located on the central axis of the large tank and is connected to the l...

AI Technical Summary

Problems solved by technology

The space inside the tank is small, the number of electrodes and movable shields is large, the weight is too large, the installation and construction environment is harsh, the efficiency is low, and the quality is difficult to guarantee

[0005] Second, three-phase current imbalance

The electrodes are arranged in a hanging manner, which has poor stability

When working, the lower pump water directly flushes the electrodes, which easily distorts the electrodes, reduces the distance between the electrodes and the zero electrode, and increases the single-phase discharge, resulting in unbalanced three-phase currents, affecting the stability of the circuit, and also causing the zero voltage to return. Zero, device case live

[0006] Third, the tank is charged and the safety is poor

The zero electrode is directly connected to the large tank, causing the tank to be charged

Complicated insulating and isolating devices must be installed at all parts connected to the large tank, such as the support, the connecting pipe, and the stepping electrode, which will directly increase the production cost

[0007] Fourth, the height of the equipment is large

Such a design will increase the cost of the client computer room and reduce the applicability of the equipment

[0008] Fifth, the traction shaft is difficult to seal

The relative movement between the traction shaft and the tank is vertical movement, the sealing surface is large, and the dynamic sealing effect is not good

[0009] Sixth, the cost of electrode production is high

The jar-shaped electrode is essentially a small pressure vessel, and oval heads need to be welded at both ends of the seamless pipe. The welding requirements are relatively high and the equipment cost will be increased.
