Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a sterile water treatment device for explosion-proof areas. Background Technology

[0002] In conventional pure water processes, ozone or ultraviolet sterilization is typically used for end-point sterilization. Ozone sterilization is a common method. Conventional ozone generators generally use high-voltage ionization of air to produce O3 ozone molecules, which then sterilize microorganisms in the pure water to meet the requirements for sterile pure water.

[0003] However, in explosion-proof areas, the presence of flammable and explosive gases or dust poses significant safety hazards when using high-voltage ionization processes, failing to meet explosion-proof electrical design specifications. Therefore, traditional ozone generators cannot be directly applied to pure water sterilization processes in explosion-proof areas, hindering the application of sterile pure water and limiting related production or experimental activities.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Please refer to Figure 1 , Figure 2 and Figure 3 The present invention relates to an explosion-proof sterile water treatment device, comprising an explosion-proof enclosure 1 and a water treatment mechanism 2 disposed inside the explosion-proof enclosure 1. The explosion-proof enclosure 1 is further provided with a control panel 3 for controlling the water treatment mechanism 2, an explosion-proof air conditioner 4 for cooling, and a micro-positive pressure treatment component 5 for maintaining a micro-positive pressure inside the explosion-proof enclosure 1.

[0028] The micro-positive pressure treatment component 5 includes a compressed air compressor 51 and a ventilation section formed on the explosion-proof enclosure 1. The compressed air compressor 51 supplies compressed air into the explosion-proof enclosure 1 to make the internal air pressure of the explosion-proof enclosure 1 greater than the external air pressure of the explosion-proof enclosure 1, thereby allowing hazardous gases and dust from outside the explosion-proof enclosure 1 to enter the explosion-proof enclosure 1. The ventilation section includes a plurality of ventilation holes 52, all of which penetrate the explosion-proof enclosure 1. Specifically, the plurality of ventilation holes 52 are arranged in a matrix to form a rectangular ventilation section. The function of the ventilation holes 52 is to replace the gas inside the explosion-proof enclosure 1, ensuring that any flammable gases or impurities inside the enclosure are completely discharged, thereby ensuring the safety of the environment inside the enclosure. The ventilation holes 52, in conjunction with the compressed air unit 51, continuously replenish the enclosure with clean protective gas (such as air or inert gas), maintaining a slightly positive pressure inside the enclosure to prevent the entry of external hazardous gases or dust. The ventilation holes 52 can also remove the heat generated by the electrical components inside the enclosure during operation, preventing excessively high temperatures that could affect the normal operation of the equipment. The explosion-proof enclosure 1 is equipped with a pressure sensor (not shown in the figure) capable of detecting the air pressure inside the enclosure. Both the pressure sensor and the compressed air unit 51 are connected to the control panel 3. The user sets the target pressure value inside the explosion-proof enclosure 1 through the control panel 3. The pressure sensor sends the detected pressure value signal to the control panel 3, which compares this detected value with the target value to adjust the delivery rate of the compressed air unit 51 as needed. The explosion-proof box 1 is also equipped with a cleaning component 6 at the position corresponding to the ventilation section to clean the ventilation section and prevent it from becoming clogged.

[0029] Please refer to Figure 4 , Figure 5 and Figure 6The cleaning component 6 includes a brush roller 61 for cleaning the ventilation hole 52 and a drive member 62 for reciprocating the brush roller 61. The brush roller 61 is arranged along the width or height direction of the ventilation section, and the drive member 62 drives the brush roller 61 to reciprocate along the height or width direction of the ventilation section to clean the ventilation hole 52. In the illustrated embodiment, the brush roller 61 is preferably arranged facing each other along the height of the ventilation section and reciprocates along the width direction of the ventilation section. Specifically, a fixing block 63 is provided on the inner wall of the explosion-proof box 1 at a position corresponding to the upper part of the ventilation section. The fixing block 63 is horizontally arranged along the width direction of the ventilation section, and the length of the fixing block 63 is greater than the width of the ventilation section. A groove 631 is formed inside the fixing block 63 along its own length direction. The groove 631 extends downward through the fixing block 63, and a slider 632 is slidably arranged in the groove 631. The slider 632 can slide along the length direction of the groove 631. The brush roller 61 is cylindrical and its outer circumference is covered with brushes. The brush roller 61 is vertically positioned below the fixed block 63, corresponding to the ventilation section. The upper end of the brush roller 61 has a connecting shaft 611 coaxial with it, which connects to the slider 632. Specifically, the connecting shaft 611 is rotatably connected to the slider 632, meaning it can rotate relative to the slider 632 around its own axis, thus driving the brush roller 61 to rotate around its axis. It is important to note that the height of the slider 632 is less than the internal height of the groove 631. A raised edge 633 is provided at the lower opening of the groove 631 to prevent the slider 632 from dislodging downwards from the groove 631. A rack 634 is provided inside the groove 631 above the slider 632, and the rack 634 is arranged along the length of the groove 631. The upper end of the connecting shaft 611 is fixedly connected to a gear 612 that meshes with the rack 634. The driving component 62 is configured as a cylinder (in other embodiments, the driving component 62 can also be other power devices, as long as they can drive the brush roller 61 to reciprocate). The cylinder is horizontally disposed on the inner wall of the explosion-proof box 1. The output shaft of the cylinder extends horizontally and is fixedly disposed with a connecting rod 621. The end of the connecting rod 621 away from the cylinder is connected to the brush roller 61. Specifically, the connecting shaft 611 and the end of the connecting rod 621 are rotatably connected, that is, the connecting shaft 611 can rotate relative to the connecting rod 621 around its own axis. When the cylinder is started, the driving shaft of the cylinder pushes the connecting rod 621 to move horizontally. At the same time, the connecting rod 621 rotates under the action of the gear 612 and the rack 634 to clean the ventilation section and prevent the ventilation holes 52 from being blocked by dust and other impurities.

[0030] Please refer to Figure 7 The water treatment unit 2 includes a pure water tank 21, a circulating pump 22, a UV sterilizer 23, a conductivity monitor 24, an ozone concentration monitor 25, and a PEM ozone device 26. The pure water tank 21, the circulating pump 22, the UV sterilizer 23, and the conductivity monitor 24 are sequentially connected via a delivery pipe 27. The PEM ozone device 26 is mounted on the pure water tank 21 and communicates with the interior of the tank to regulate the ozone concentration. The ozone concentration monitor 25 is mounted on the delivery pipe 27 to monitor the ozone concentration in the water flowing out of the pure water tank 21. An outlet 28 is provided on the delivery pipe 27, and a solenoid valve 29 is installed at the outlet 28. The solenoid valve 29, the circulating pump 22, the UV sterilizer 23, the conductivity monitor 24, and the PEM ozone device 26 are all connected to the control panel 3. Users can set the target conductivity and target ozone concentration of the water quality through the control panel 3. The conductivity monitor 24 and the ozone concentration monitor 25 transmit the detected numerical signals to the control panel 3, which compares them with the target values ​​to adjust the working status of the UV sterilizer 23 and the PEM ozone device 26.

[0031] One embodiment of the explosion-proof sterile water treatment device of this utility model operates as follows: The circulating pump 22 pumps water out of the pure water tank 21. The pumped water passes sequentially through the UV sterilizer 23, the conductivity monitor 24, and the ozone concentration monitor 25. The user can monitor the readings of the conductivity monitor 24 and the ozone concentration monitor 25 through the control panel 3, thereby monitoring the status of the circulating water. The control panel 3 can also control the operation of the PEM ozone device 26 and the UV sterilizer 23, thereby making real-time adjustments to the water treatment process.

[0032] The explosion-proof air conditioner 4 is connected to the control panel 3 via a signal. The user can control the operating temperature of the explosion-proof air conditioner 4 through the control panel 3. The function of the explosion-proof air conditioner 4 is to remove the heat generated by the various devices inside the explosion-proof box 1.

[0033] As the device is used for an extended period, the explosion-proof enclosure 1 contains several electrically powered devices, including a circulating pump 22, an explosion-proof air conditioner 4, and a compressed air compressor 51. The heat generated during operation raises the air temperature, causing the hot air to rise. This convection current carries away surrounding dust, leading to dust accumulation near the ventilation vent 52. This can easily clog the ventilation vent 52, affecting its ventilation efficiency and thus the overall working environment within the explosion-proof enclosure 1. To address this, the cylinder can be configured via the control panel 3 to clean the ventilation vent 52 periodically, ensuring its unobstructed flow. During cleaning, the cylinder's drive shaft pushes the connecting rod 621 horizontally, while the connecting rod 621 rotates under the interaction of the gear 612 and the rack 634, driving the brush roller 61 to clean the ventilation section. Compared to simple linear movement, the brush roller 61 can rotate to increase the contact frequency and friction between the bristles and the surface of the object, thereby improving the cleaning effect. At the same time, the rotation of the brush roller 61 also makes it easier to shake off the dust adhering to it, reducing the rate at which dust accumulates on the brush roller 61.

[0034] Compared with existing technologies, this invention's explosion-proof sterile water treatment device effectively improves water treatment efficiency and quality by integrating real-time monitoring and control functions, while optimizing the working environment inside the explosion-proof enclosure. Furthermore, the cleaning component uses a cylinder-driven brush roller to periodically clean the ventilation holes. Its combination of rotation and horizontal movement significantly improves cleaning effectiveness, reduces dust accumulation, and keeps the ventilation holes clear, thereby further optimizing the overall working environment inside the explosion-proof enclosure. This design not only improves the automation and intelligence level of the equipment but also reduces maintenance costs, extends equipment lifespan, and enhances operational convenience, demonstrating significant practical value and market competitiveness.
