Description
Technical Field
[0001] This utility model relates to the field of disinfection equipment, and more specifically, to a sodium hypochlorite generator cabinet. Background Technology
[0002] Traditional sodium hypochlorite generator cabinets typically employ a highly integrated design, combining the brine preparation system, electrolysis system, and hydrogen venting system within a single enclosed space to achieve structural compactness. However, this integrated approach has significant drawbacks: the brine preparation system, due to prolonged contact with highly corrosive solutions, is prone to leakage, which can lead to chloride ion corrosion of critical components of the electrolysis system (such as electrode plates, circuit controllers, and power modules) within the cabinet, shortening equipment lifespan; simultaneously, the passive design of the hydrogen venting system within the cabinet makes it difficult to effectively dilute the gas in the confined space, and if the electrolysis cell seal fails or the pipeline becomes blocked, hydrogen accumulation may pose a fire and explosion hazard. Therefore, there is an urgent need for a cabinet structure that separates the brine preparation and hydrogen venting functions, with the electrolysis system at its core. This structure would avoid the coexistence of corrosion sources and hazardous gases in a confined space, while simplifying the internal component layout, fundamentally improving electrolysis efficiency and equipment safety.

[0030] Example:
[0031] A sodium hypochlorite generator cabinet 1 includes a cabinet body with a mounting plate 23 inside. The mounting plate 23 is vertically arranged and divides the interior of the cabinet body into a front compartment 21 and a rear compartment 22. The front compartment 21 is used to install piping equipment, and the rear compartment 22 is used to install electrical switches and a soft water tank. An inner lining plate 104 is provided at the bottom of the cabinet body, and a drain port 105 is provided on the inner lining plate 104. A lifting lug 13 is provided at the top of the cabinet body, and a pad 16 is provided at the bottom of the cabinet body. The cabinet 1 is specifically designed for the electrolysis system of a sodium hypochlorite generator, and achieves functional zoning and risk isolation through structural optimization. The interior of the cabinet body is divided into a front compartment 21 (piping equipment area) and a rear compartment 22 (electrical control area) by the vertical mounting plate 23. The front compartment 21 centrally houses electrolyte delivery pipes, reaction interfaces, and other liquid-contacting components, while the rear compartment 22 independently installs electrical switches, soft water tanks, and other equipment, forming a physical isolation barrier. The bottom inner lining plate 104 is equipped with a drain port 105 for diverting leaked liquid; the top lifting lug 13 and the bottom pad 16 ensure transport stability. The brine preparation and hydrogen venting system are externally located in the cabinet 1, with only the core electrolysis function module retained.
[0032] In one possible embodiment, the cabinet includes a top frame 102 and a bottom frame 103; the top frame 102 and the bottom frame 103 are connected by columns 101 to form a cubic frame structure; the cabinet has a left side panel and a right side panel 17 that are detachably connected to the columns 101 on both sides. Optionally, the left and right side panels 17 are connected to the columns 101 by bolts, and the detachable design of the side panels allows users to flexibly adjust the opening and closing state of the side panels according to heat dissipation needs (such as temporarily removing the side panels to enhance air circulation in high-temperature environments) to prevent the equipment inside the cabinet from overheating.
[0033] The cabinet is equipped with a front door 11 and a rear door 18 at the front and rear, respectively. The front door 11 and the rear door 18 are connected to the uprights 101 via hinges. The upper and lower ends of the mounting plate 23 are connected to the top frame 102 and the bottom frame 103, respectively. Optionally, the upper and lower ends of the mounting plate 23 are provided with a first connecting part and a second connecting part, respectively. An upper mounting seat is welded to the bottom of the top frame 102 corresponding to the position of the first connecting part, and a lower mounting seat is welded to the top of the bottom frame 103 corresponding to the position of the second connecting part. Both the upper and lower mounting seats are provided with through bolt holes, and the inner side of the upper mounting seat is provided with a positioning boss. During installation, the first connecting part at the top of the mounting plate 23 is embedded in the positioning boss of the upper mounting seat, and the second connecting part at the bottom is aligned with the lower mounting seat. The mounting plate 23 is then tightened and fixed by passing through the upper mounting seat, the first connecting part, the lower mounting seat, and the second connecting part in sequence with through bolts. This solution achieves rapid positioning and installation of the mounting plate 23.
[0034] A front exhaust vent 111 is provided below the front door 11; a front dustproof net 113 is provided on the back of the front exhaust vent 111; a rear exhaust vent 181 is provided below the rear door 18; a rear dustproof net 182 is provided on the back of the rear exhaust vent 181; the front dustproof net 113 is connected to the front door 11; an observation window 112 is provided above the front door 11. The cabinet 1 includes a top plate 12; a ventilation opening 14 and a reserved opening 15 are provided on the top plate 12, the reserved opening 15 being used for the product pipeline to extend. The front exhaust vent 111 and the rear exhaust vent 181 are independently provided below the front and rear doors 18, forming a through airflow channel. Utilizing the principle of natural rising of hot air, this promotes continuous convection between the air inside the cabinet 1 and the cold air outside (thermal chimney effect), significantly improving heat dissipation efficiency. The front dust filter 113 and rear dust filter 182 are installed close to the back of the front exhaust vent and rear exhaust vent 181, respectively. They adopt a multi-layer metal mesh or nylon filter structure and use a triple filtration mechanism of interception, adsorption and inertial impact to block external dust, insects and other foreign objects from entering the cabinet 1. At the same time, they avoid reducing filtration efficiency due to airflow turbulence caused by the dust filter being too far from the exhaust vent. An observation window 112 is integrated above the front door 11. It is made of double-layer tempered glass or polycarbonate transparent sheet. The inner layer can be coated with explosion-proof film or heated anti-fog coating. It allows operators to directly observe the operating status of the equipment inside the cabinet 1 (such as indicator lights and instrument panel readings) without opening the door, reducing the risk of heat dissipation efficiency fluctuations and dust intrusion caused by frequent door opening.
[0035] Preferably, the front dustproof net 113 and the rear dustproof net 182 are fixed to the front and rear hatches 18 by plug-in slots or magnetic attraction, which can be disassembled, cleaned or replaced by hand without additional tools, ensuring long-term dustproof performance, especially suitable for industrial scenarios with high dust concentration.
[0036] Optionally, a panel 31 is provided below the rear hatch 18; the panel 31 has a first through hole 311 and a second through hole 312; the first through hole 311 is used for pipe connection; the second through hole 312 is used for wiring connection. Preferably, three first through holes 311 and three second through holes 312 are provided. The panel 31 is fixedly connected to the column 101. The panel 31 is located on the back and bottom of the cabinet, and the first through holes 311 and second through holes 312 are provided on the panel 31 for connecting pipes and wiring. The layout is reasonable and avoids safety hazards caused by complex wiring at the front of the cabinet.
[0037] In one possible embodiment, a crossbeam is provided inside the front compartment 21; the crossbeam is used to fix the electrolytic cell; the crossbeam includes longitudinal beams 41; one end of the longitudinal beam 41 is connected to the column 101 and the other end is connected to the mounting plate 23; it includes two longitudinal beams 41; the two longitudinal beams 41 are respectively arranged on the left and right sides of the front compartment 21; the two ends of the crossbeam 42 are respectively connected to the two longitudinal beams 41. This technical solution solves the problems of insufficient rigidity, low disassembly and assembly efficiency, and poor layout adaptability of traditional electrolytic cell fixing methods by setting a modular crossbeam structure composed of symmetrical longitudinal beams 41, crossbeams 42 and mounting plate 23 in the front compartment 21. Specifically, the longitudinal beams 41 on both sides are rigidly connected to the compartment body through the column 101, and the crossbeam 42 spans the longitudinal beams 41 to form a load-bearing frame. The weight of the electrolytic cell is evenly transferred to the column 101 by multi-point distributed support, which significantly improves the vibration and impact resistance.
[0038] Preferably, the longitudinal beam 41 and the mounting plate 23 are connected by bolts for easy removal. Combined with the quick-locking design of the crossbeam 42, tool-free positioning installation and maintenance of the electrolytic cell can be achieved. Furthermore, by adjusting the spacing of the longitudinal beam 41 and the opening of the mounting plate 23, it can be adapted to electrolytic cells of different sizes, meeting the needs of high load, frequent maintenance and compact space in chemical, energy equipment and other scenarios.
[0039] In one possible embodiment, an inner door 51 is provided inside the forward cabin 21; the inner door 51 is used to secure an operation panel with a display; a display window 511 is provided on the inner door 51; the display of the operation panel with the display is shown to the outside through the display window 511. The position of the display window 511 corresponds to the position of the observation window 112. This facilitates viewing the information on the display without opening the forward cabin door 11.
[0040] Preferably, the inner door 51 is connected to the column 101 via inner door frames 52 on both sides; the inner door frame 52 is provided with a pin hole 521; the inner door 51 is provided with a through shaft hole; a pin passes through the pin hole 521 and the shaft hole to fix the inner door 51 to the inner door frame 52. The pin is a removable latch. When both sides of the inner door 51 are connected to the inner door frame 52 via latches, it can fix the inner door 51. When one side of the latch is removed, the inner door 51 can be opened.
[0041] Preferably, a first electrical rack and a second electrical rack are arranged on the left side of the rear compartment 22; the first electrical rack and the second electrical rack are arranged vertically; the soft water tank is located on the right side of the rear compartment 22. The electrical rack is used to install air switches, relays, and other equipment, and works with the operation panel to control the equipment in the cabinet 1.
[0042] Preferably, the inner lining plate 104 has an inclined surface facing the drain port 105; the inclined surface is used to guide the liquid to the drain port 105 and discharge it from the cabinet; the inner lining plate 104 is made of PE material. The cabinet and mounting plate 23 are made of anti-corrosion sheet material; the anti-corrosion sheet material consists of a metal layer 61, a primer layer 62, and a PTFE layer 63 from the inside out. The inclined surface of the inner lining plate 104 is designed to face the drain port 105. Utilizing the liquid's own weight and the low surface tension characteristics of PE material (contact angle > 90°), the liquid forms a continuous liquid film along the inclined surface and is quickly guided to the drain port 105, avoiding the risk of localized corrosion or electrical short circuits caused by liquid accumulation inside the cabinet. The measured drainage efficiency is more than 40% higher than that of a flat-bottom structure. The inner lining plate 104 is made of PE (polyethylene) material, and the seamless inclined surface structure is achieved through an injection molding process. Its acid and alkali resistance and organic solvent resistance complement the anti-corrosion layer of the cabinet, making it particularly suitable for chemical, electroplating, and other highly corrosive liquid exposure scenarios. The anti-corrosion material of the cabinet and mounting plate 23 adopts a composite structure of "metal layer (such as aluminum alloy) - primer layer (epoxy resin) - PTFE (polytetrafluoroethylene) layer". The primer layer enhances the adhesion between the metal layer and the PTFE layer through chemical bonding. The PTFE layer plays a role in its inertness, low coefficient of friction and temperature resistance (-200℃~260℃), effectively blocking the penetration of corrosive media. The coating peeling is avoided by high-temperature sintering and curing process. The measured salt spray test life is >5000 hours (ISO 9227 standard).
