The foreign matter attached to the electrode plate acts as a factor of damaging the expensive electrode and reducing the disinfection efficiency, and may increase the maintenance cost of the electrolysis device.

In order to solve the above problems, the present invention is to provide an electrode protective cover that can minimize the foreign matter attached to the electrode plate end in the electrolysis device for water treatment.

The present invention is to pass through the water, to cover the end of the electrode plate provided in the electrolysis tank provided with the inlet and outlet, respectively on one side and the other side, the bottom surface is installed along the electrode plate end located on the inlet side part; Side portions extending from the bottom portion to the front and rear surfaces of the electrode plate, respectively; It provides an electrode protective cover of the electrolysis device for water treatment.

The electrode plate is plate-shaped or mesh-shaped electrode reaction portion; A plate-type current applying unit provided at both ends of the electrode reaction unit; The electrode protective cover is characterized in that for covering the current application.

In addition, the bottom portion and the edge connecting the side portion is characterized in that the curved shape, the side portion is characterized in that the outer surface of the side portion is composed of an inclined surface so that the thickness becomes thicker toward the bottom side, the electrode protective cover is It is characterized in that the fitting to the electrode plate.

In addition, the present invention provides a coupling protrusion formed on each of the front and rear of the current applying unit; A coupling groove formed in a shape corresponding to the coupling protrusion on an inner surface of the side portion of the electrode protective cover; Is formed, the coupling groove is characterized in that the electrode protection cover is fitted to the electrode plate by sliding along the coupling projection.

The electrode protective cover is characterized in that the insulating material, the insulating material is characterized in that the synthetic resin or synthetic rubber.

According to the present invention as described above it can minimize the foreign matter attached to the end of the electrode plate can increase the lifetime of the electrode and the disinfection efficiency of ballast water. Therefore, it is expected to reduce the cost of maintenance of the electrolysis device.

Electrode protection cover 30 of the present invention, as shown in Figure 1, the water 40 is passed through, the electrode plate is installed in the electrolysis tank 10 provided with inlet and outlet respectively on one side and the other side (20) It is for covering an end part.

Here, the water 40 includes not only ballast water, but also wastewater or other raw water for generating disinfectant water, which can be treated by an electrolysis device.

As shown in FIGS. 2A to 2C, the electrode protective cover 30 includes a bottom portion 32 installed along an end portion of the electrode plate 20 positioned at the inlet side; Side portions (34) extending from the bottom portion (32) to the front and rear surfaces of the electrode plate (20), respectively; Characterized in that consists of.

The electrode protective cover 30 may be installed at both the inlet and outlet of the water 40, but foreign matter at the end of the electrode plate 20 located at the inlet side of the water 40 is introduced into the electrolysis tank 10. Since the possibility of this attachment is relatively large, the electrode protective cover 30 may be provided only at the end of the electrode plate 20 located on the inlet side.

In the present invention, the electrode protective cover 30 may be fitted and fitted to insert the electrode plate 20 from the outside of the electrode plate 20.

In particular, as shown in Figure 3a, the engaging projections 26 are formed to protrude on the front and rear of the current application portion 24, respectively; A coupling groove 36 formed in a shape corresponding to the coupling protrusion 26 on a side surface 34 of the electrode protective cover 30; Is formed, the coupling groove 36 is slid along the coupling protrusion 26 is possible to configure the electrode protective cover 30 is fitted to the electrode plate 20.

Therefore, the electrode protective cover 30 of the present invention can be applied to the existing electrolysis device without additional costs.
