A vertical electrode hot water boiler device

Abstract

The invention discloses a vertical electrode hot water boiler device. The middle part of the insulating shell has a three-lobed opening as a water guide, and the insulating shell has three heating spaces connected on the inside; the three electrode plates are bent rectangular plates. It is used to fit the inner side wall of the electrode support plate; the central tube of the movable shield is connected with three rectangular plates with an angle of 120° and is used to isolate the shield plate of the electrode plate; it passes through the nut coaxially arranged with the central tube and is connected with the The upper end of the lead screw that the nut thread fits passes through the large tank and is connected with a stepping motor. The problem of unstable electrode structure is solved through a new structural form, and the zero electrode is canceled; by optimizing the electrode design, the overall height of the equipment is reduced, the size is reduced, and the applicability of the equipment is improved; the problem of tank electrification is solved, and the The equipment is safe, and the cost of the equipment is reduced; the difficulty of installing internal parts is reduced, the installation cost is saved, and the quality assurance ability is improved; and the sealing reliability is improved by optimizing the sealing structure.

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 for installation of internal parts and maintenance equipment. Three-phase small pot-shaped electrodes are symmetrically distributed in the tank, and each electrode corresponds to its own cylindrical zero-position electrode. A triangular connection board is used between the zero electrodes to realize the circuit conduction and achieve the purpose of zero potential. The zero electrode is directly fixed in the large 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 connect...

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.
