Description

Technical Field

[0001] The invention relates to the technical field of electrolytic ozone production, and in particular to a multi-layer sealed ozone water generating device. Background Art

[0002] Ozone water is a green, environmentally friendly, and highly efficient disinfectant with no byproducts. The existing low-voltage electrolysis method for producing ozone is currently the most widely used and most efficient method for producing ozone water. It uses boron-doped diamond sheets and solid electrolyte membranes to complete the electrolysis reaction. Based on the excellent chemical properties of boron-doped diamond electrodes, in order to give full play to the performance of boron-doped diamond electrodes, it is necessary to construct an electrolytic cell structure for installing electrodes. Most of the existing electrolytic cell structures focus on heat dissipation, disassembly, gas blockage, life, and ease of manufacturing. In practice, the sealing of the overall package has a great impact on the performance of electrode electrolysis. In long-term use, the existing electrode packaging structure is prone to electrode sheet breakage and poor contact; the ozone and hydrogen bubbles generated by the electrode sheet affect the gap between the electrode sheets, reducing the electrolysis efficiency; the part where the electrode is connected to the circuit is prone to water leakage. Therefore, a reliably sealed ozone water generation device is now needed.

The ozone generating device only considers the stability of the liquid supply during the electrolytic production of ozone, and does not fully consider the influence of the sealing of the electrolytic chamber on the efficiency and life of the electrolytic production of ozone, resulting in unstable amount of ozone produced.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-Figure 6 As shown, the present embodiment discloses a multi-layer sealed ozone water generating device, comprising a shell 1, an end cover 2, an anode assembly 4, a cathode assembly 5 and an electrode sheet assembly 3, wherein the anode assembly 4, the cathode assembly 5 and the electrode sheet assembly 3 are all arranged in the shell 1, and the anode assembly 4 and the cathode assembly 5 are respectively connected to the electrode sheet assembly 3, an electrolysis chamber 11 and an electrode chamber 12 are arranged in the shell 1, the electrode chamber 12 is arranged above the electrolysis chamber 11, the electrode chamber 12 penetrates the top wall of the shell 1 to form an opening, the end cover 2 is arranged on the opening, the electrode sheet assembly 3 is arranged in the electrolysis chamber 11, the anode assembly 4 and the cathode assembly 5 are both partially arranged in the electrode chamber 12, the electrode chamber 12 and the electrolysis chamber 11 are separated by a solid wall, the electrode sheet assembly 3 will not affect the anode assembly 4 and the cathode assembly 5 during operation, and the working state of electrolysis of water and ozone is stable.

[0029] Furthermore, the anode assembly 4 includes a first sealing gasket 41, an anode column 42, a first elastic element 43 and a second sealing gasket 44. The first sealing gasket 41, the first elastic element 43 and the second sealing gasket 44 are sequentially sleeved on the anode column 42. The first elastic element 43 applies pressure toward the electrolysis chamber 11 to the anode column 42. A first retaining ring is provided in the middle of the anode column 42. The first retaining ring protrudes from the surface of the anode column 42 and is used to limit the anode column 42 from falling into the electrolysis chamber 11. One end of the first elastic element 43 contacts the first retaining ring, and the other end contacts the end cover 2, pressing one end of the anode column 42 onto the anode sheet 31 to form a current path. The first sealing gasket 41 seals the gap between the anode column 42 and the electrode chamber 12, and the second sealing gasket 44 fixes the other end of the anode column 42.

[0030] Preferably, the anode assembly 4 also includes a first conductive belt 45, which is sleeved on the anode column 42 and compressed by the second sealing gasket 44. The first conductive belt 45 is connected to the external power supply line through the notch 62 on the side cover 6.

Compared with the existing glue filling from the end cover 2, when the glue flows to the electrode, the sealing contact is prone to form bubbles, resulting in poor sealing effect. Glue filling from the notch 62 and the hole into the electrode cavity 12 can be filled along the axial direction of the electrode column to prevent the airflow from escaping in time to form bubbles when the glue contacts the bottom wall of the electrode cavity 12, which can improve the effect of the glue filling process.

[0031] Furthermore, the cathode assembly 5 includes a third sealing gasket 51, a cathode column 52, a second elastic element 53 and a fourth sealing gasket 54. The third sealing gasket 51, the second elastic element 53 and the fourth sealing gasket 54 are sequentially sleeved on the cathode column 52.

The second conductive belts 55 on the cathode column 52 and the anode column 42 are connected to the external power supply circuit through the notch 62 on the side cover 6.

[0034] Furthermore, the electrode sheet assembly 3 includes an anode sheet 31 , a diaphragm 32 and a cathode sheet 33 stacked in sequence, one end of the anode column 42 abuts against the anode sheet 31 , and one end of the cathode column 52 passes through the anode sheet 31 and the diaphragm 32 and abuts against the cathode sheet 33 .

[0035] More preferably, the anode plate 31 is a boron-doped diamond electrode plate.

The two sides of the electrode sheet assembly 3 are respectively clamped in the groove 14. The protrusion 13 is below the electrode sheet assembly 3. There is a gap between the top of the protrusion 13 and the electrode sheet assembly 3, which can prevent the electrode sheet assembly 3 from bending and deforming downward and falling, thereby ensuring the stable and efficient operation of the electrode sheet assembly 3. The groove 14 is composed of two ribs extending from the side wall of the electrolysis chamber 11. The electrode sheet assembly 3 is clamped by the two ribs to support the electrode sheet assembly 3.

[0037] Preferably, the shell 1 also includes a sealing groove 15, which is arranged on the bottom wall of the electrode cavity 12.

The other end of the anode column 42 and the cathode column 52 has movable space to prevent the electrode sheet assembly 3 from being damaged by force, thereby extending the service life of the electrode sheet assembly 3.
