Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, specifically a secondary water supply equipment capable of automatic disinfection and sterilization. Background Technology

[0002] Secondary water supply refers to a system where units or individuals store and pressurize urban public water supply or self-built water supply facilities before distributing it to users or for their own use through pipelines. Secondary water supply systems are primarily established to compensate for insufficient pressure in municipal water supply pipelines and to ensure water supply for residents living in high-rise buildings. General water supply equipment only has pressurization capabilities and cannot filter the water. After prolonged use, scale and other impurities easily accumulate inside the water supply network, leading to impurities in the water supplied to residents and affecting water quality.

[0007] Preferably, the sedimentation device includes a connecting pipe, an upper cylinder seat, a lower cylinder seat, a mounting ring, a sedimentation box, a guide plate, a mounting threaded ring bracket, and a drain pipe. The connecting pipe is installed at the bottom of the pressurization tank, the upper cylinder seat is installed at the bottom of the connecting pipe, the lower cylinder seat is installed at the bottom of the upper cylinder seat via threads, the mounting ring is installed on the outer wall of the lower cylinder seat, the sedimentation box is installed below the mounting ring via threads, the guide plate is installed on the inner side of the mounting threaded ring bracket via a bracket, the mounting threaded ring bracket is installed on the inner side of the sedimentation box via threads, and the drain pipe for draining water is installed on the outer wall of the upper cylinder seat.

[0008] Preferably, the filtration device includes a guide vane, an outer filter cover, a lower positioning ring frame, an upper positioning ring frame, and an inner filter cartridge. The guide vane is installed on the inner wall of the lower cartridge seat, the outer filter cover is installed on the inner side of the guide vane, the lower positioning ring frame is installed on the bottom inner wall of the outer filter cover, the upper positioning ring frame is installed on the bottom end of the drain pipe, the bottom end of the inner filter cartridge is snapped into the inner side of the lower positioning ring frame, and the top end of the inner filter cartridge is snapped into the inner side of the inner filter cartridge.

[0011] Preferably, the pressurization tank is equipped with an ultraviolet lamp for auxiliary sterilization of the water.

[0012] Compared with the prior art, this utility model provides a secondary water supply device capable of automatic disinfection and sterilization, which has the following beneficial effects:

[0013] 1. This secondary water supply equipment, which can automatically disinfect and sterilize, performs two filtrations on the water body through the cooperation of sedimentation and filtration devices. It filters and separates residual scale and impurities in the water body, thereby improving the water quality. Through the dual filtration method, large particles of impurities are filtered first, which can improve the filtration effect of the inner filter cartridge on fine particles and extend the filter life.

[0014] 2. This secondary water supply equipment, capable of automatic disinfection and sterilization, uses guide vanes to obstruct the flowing water, causing it to flow along a spiral trajectory. As the water flows along this spiral trajectory, the rotation causes impurities inside the water to move outward under centrifugal force. The impurities move downward along the spiral trajectory, preventing them from clogging the outer filter cover. After falling to the surface of the guide vanes, the impurities diffuse outward and move below the guide vanes. Floating impurities will float upward along the outside of the guide vanes after settling and enter the sedimentation box, located on the outside of the lower cylinder seat. This prevents floating impurities from rising into the lower cylinder seat and affecting the filtration effect. By collecting the filtered impurities, the equipment prevents impurities from remaining on the outside of the outer filter cover and affecting the filtration effect. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a secondary water supply device capable of automatic disinfection and sterilization, including a booster tank 1, a sedimentation device 4 for sedimentation and centrifugal separation filtration, and a filtration device 5 for secondary filtration of water. The bottom of the booster tank 1 is equipped with a support bracket 2, the top of the booster tank 1 is equipped with a water supply pipe 3, the bottom of the booster tank 1 is equipped with a sedimentation device 4 for sedimentation and centrifugal separation filtration, and the sedimentation device 4 is equipped with a filtration device 5 for secondary filtration of water.

[0022] Furthermore, the sedimentation device 4 includes a connecting pipe 41, an upper cylinder seat 42, a lower cylinder seat 43, a mounting ring 44, a sedimentation box 45, a guide plate 46, a mounting threaded ring bracket 47, and a drain pipe 48. The connecting pipe 41 is installed at the bottom of the pressure tank 1, the upper cylinder seat 42 is installed at the bottom of the connecting pipe 41, the lower cylinder seat 43 is installed at the bottom of the upper cylinder seat 42 by threads, the mounting ring 44 is installed on the outer wall of the lower cylinder seat 43, the sedimentation box 45 is installed below the mounting ring 44 by threads, the guide plate 46 is installed on the inner side of the mounting threaded ring bracket 47 by a bracket, the mounting threaded ring bracket 47 is installed on the inner side of the sedimentation box 45 by threads, and the drain pipe 48 for draining water is installed on the outer wall of the upper cylinder seat 42. The sedimentation device 4 settles and filters large particulate impurities in the water and stores the filtered impurities.

[0023] Furthermore, the filtration device 5 includes a guide vane 51, an outer filter cover 52, a lower positioning ring frame 53, an upper positioning ring frame 54, and an inner filter cartridge 55. The guide vane 51 is installed on the inner wall of the lower cartridge seat 43, the outer filter cover 52 is installed on the inner side of the guide vane 51, the lower positioning ring frame 53 is installed on the bottom inner wall of the outer filter cover 52, the upper positioning ring frame 54 is installed on the bottom end of the drain pipe 48, the bottom end of the inner filter cartridge 55 is snapped into the inner side of the lower positioning ring frame 53, and the top end of the inner filter cartridge 55 is snapped into the inner side of the inner filter cartridge 55. The filtration device 5 filters the water twice, improving the filtration effect and quality through layered filtration. The guide vane 51 blocks the water, allowing it to flow and flush rapidly outside the outer filter cover 52, preventing blockage and extending its service life.

[0024] Furthermore, the guide vane 51 is spiral-shaped, and the outer side of the guide vane 51 bends downward. When the water flows along the guide vane 51, the impurities in the water are shifted to the outside under the action of centrifugal force, and are separated by centrifugal force. At the same time, the outer side of the guide vane 51 bends downward, so that the impurities on the surface of the guide vane 51 will move to the outside, preventing the outer filter cover 52 from being blocked.

[0025] Furthermore, the top of the guide plate 46 is conical, and the diameter of the guide plate 46 is larger than the diameter of the lower cylinder seat 43. The obstruction of the guide plate 46 causes impurities falling below the guide plate 46 to float to the inside of the sedimentation box 45 at the position outside the bottom of the lower cylinder seat 43 when they float, thus preventing impurities from entering the interior of the lower cylinder seat 43.

[0026] Furthermore, the inside of the pressurization tank 1 is equipped with an ultraviolet lamp for auxiliary sterilization of the water, which performs a final auxiliary sterilization of the water before it enters the household.

[0027] During use, water is pressurized into the booster tank 1 through the water supply port 3. After entering the booster tank 1, the water is disinfected by an ultraviolet lamp, and then enters the upper cylinder seat 42 through the connecting pipe 41. From there, it flows into the lower cylinder seat 43. Inside the lower cylinder seat 43, the water flows along the guide vanes 51 on the outside of the outer filter cover 52. The guide vanes 51 restrict the water flow in a spiral trajectory. As the water flows along this spiral trajectory, large particles of impurities are deflected outwards by centrifugal force. The cleaner water on the inner side flows inwards after being filtered by the outer filter cover 52. Impurities flowing above the guide vanes 51 finally fall into the lower cylinder seat 43. Inside the sedimentation box 45, impurities fall onto the surface of the guide plate 46 and diffuse outwards, settling and storing inside the sedimentation box 45. The water filtered by the outer filter cover 52 flows inwards and is then filtered again by the inner filter cartridge 55. The water filtered by the inner filter cartridge 55 flows upwards along the inside of the inner filter cartridge 55 and is finally discharged through the drain pipe 48 for water supply. When maintenance is required, the sedimentation box 45 can be disassembled from the mounting ring 44 to clean the inside of the sedimentation box 45. The lower cylinder seat 43 can be rotated to remove the bottom of the upper cylinder seat 42, allowing for cleaning of the inside of the lower cylinder seat 43 and replacement of the inner filter cartridge 55. The maintenance operation is simple.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
