Description

Technical Field

[0001] This utility model belongs to the field of sterilization device technology, specifically relating to a sterilization device for pure water production. Background Technology

[0002] In the process of pure water production, sterilization is a key step to ensure water quality safety. Traditional pure water sterilization devices usually use a combination of mechanical stirring and chemical disinfectants, such as mixing disinfectant with pure water by stirring blades.

[0003] However, these devices have some common problems. First, most stirring devices rely solely on unidirectional rotation, lacking axial motion, resulting in dead zones in mixing and unsatisfactory sterilization effects. Second, these devices often use filter materials (such as sponges or cotton filter cartridges) to remove impurities, but these materials tend to retain a large amount of water after filtration, leading to waste of purified water and hindering practical application. Therefore, there is an urgent need for a sterilization device for purified water production.

[0004] A patent with publication number CN220618571U discloses a sterilization device for pure water production. The device includes a drive motor, a first rotating rod, a second rotating rod, a first bevel gear, a second bevel gear, a third bevel gear, and stirring blades. In use, the drive motor is started, causing the first rotating rod to rotate via its output shaft. The first rotating rod, through the meshing of the first and third bevel gears and the meshing of the third and second bevel gears, causes the second rotating rod to rotate in the opposite direction to the first rotating rod. This allows the stirring blades on the first and second rotating rods to mix and sterilize the pure water and disinfectant.

[0005] Although the above solution can improve the mixing effect by rotating the first and second rotating rods in opposite directions during use, the mixing action of the stirring blades on the two rotating rods is fixed, and the mixing effect is mainly concentrated in the horizontal direction. The mixing capacity in the vertical direction is insufficient, resulting in limited overall mixing uniformity and affecting the sterilization efficiency. Therefore, it has certain limitations in practical applications. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a sterilization device for pure water production includes a treatment tank 1, a first stirring rod 11 is provided in the treatment tank 1 for reciprocating sliding along the vertical direction, a first transmission component is provided between the first stirring rod 11 and the treatment tank 1, and a driving mechanism for driving the first stirring rod 11 to rotate is provided on the outer surface of the treatment tank 1.

[0029] Specifically, the drive mechanism includes a servo motor 3, which is fixedly mounted on the top of the processing tank 1. A first pulley 4 is fixedly mounted on the output shaft of the servo motor 3. A support tube 7 is fixedly mounted on the top of the processing tank 1, and a second pulley 5 is rotatably mounted on the top of the support tube 7. A belt is worn between the first pulley 4 and the second pulley 5 for transmission. The top of the first stirring rod 11 passes through the top of the processing tank 1 and is connected to the second pulley 5 via a sliding key.

[0030] Specifically, the first transmission component includes steel balls 20, a fixing block 19 is fixedly embedded in the top inner wall of the processing tank 1, and a reciprocating thread 18 is formed at the upper end of the first stirring rod 11. The fixing block 19, the reciprocating thread 18, and the steel balls 20 form a ball screw pair. Through the ball screw pair structure, the first stirring rod 11 slides up and down reciprocally during rotation.

[0031] In addition, a second stirring rod 15 is provided in the processing tank 1, which is limited to reciprocating sliding in the vertical direction. A second transmission component is provided between the first stirring rod 11 and the second stirring rod 15. The first stirring rod 11 drives the second stirring rod 15 to rotate in the opposite direction through the second transmission component, and also drives the second stirring rod 15 to slide up and down reciprocally through the second transmission component.

[0032] Specifically, the second transmission component includes a connecting rod 14, which is vertically slidably positioned inside the treatment tank 1. A protective shell 1401 is integrally fixed to the middle of the connecting rod 14, and a second bevel gear 12 is rotatably mounted horizontally inside the protective shell 1401. The bottom of the first stirring rod 11 extends rotatably into the protective shell 1401 and is fixedly fitted with a first bevel gear 16. The top of the second stirring rod 15 extends rotatably into the protective shell 1401 and is fixedly fitted with a third bevel gear 17. The second bevel gear 12 engages with both the first bevel gear 16 and the third bevel gear 17 for transmission.

[0033] It should be noted that the rotating connections between the first stirring rod 11 and the second stirring rod 15 and the protective shell 1401 are all sealed.

[0034] More specifically, guide rods 13 are fixedly installed on both inner walls of the treatment tank 1, and the two ends of the connecting rod 14 are slidably sleeved on the outer surface of the guide rods 13.

[0035] In addition, a mounting box 10 is fixedly installed at the bottom of the treatment tank 1. The treatment tank 1 is connected to the interior of the mounting box 10 through a drain outlet 26. A water outlet 9 is fixedly installed at the bottom of the mounting box 10. Inside the mounting box 10, a filter plate 24 is fixedly installed, and a movable plate 22 is slidably installed in a vertical direction. A dust-absorbing cotton 23 is placed between the movable plate 22 and the filter plate 24, and a third transmission component is provided between the movable plate 22 and the movable rod 8.

[0036] Specifically, several through holes are made on the movable plate 22.

[0037] Specifically, the drain outlet 26 has a built-in solenoid valve 25.

[0038] Specifically, the third transmission component includes a movable rod 8. The movable rod 8 is vertically sealed and slidably installed through the bottom of the treatment tank 1. A connecting block 21 is fixedly installed at one end of the movable rod 8 inside the treatment tank 1. The connecting block 21 is rotatably installed inside the second stirring rod 15. The other end of the movable rod 8 slides into the mounting box 10 and is fixedly connected to the movable plate 22.

[0039] In addition, the top of the treatment tank 1 is fixedly equipped with both the feed inlet 6 and the ozone generator 2, and the output end of the ozone generator 2 is connected to the interior of the treatment tank 1.

[0040] It should be noted that the ozone generator 2 and the dust-absorbing cotton 23 in this application are both conventional prior art, and will not be described in detail here. Additionally, this application features a detachable sealing door inside the mounting box 10, facilitating the replacement of the dust-absorbing cotton 23 within the mounting box 10.

[0041] Working principle: When in use, pure water and liquid treatment reagents are introduced into the treatment tank 1 through the feed port 6.

[0042] Start ozone generator 2 to input ozone into the interior of treatment tank 1 to sterilize and disinfect the air inside treatment tank 1.

[0043] The servo motor 3 is started, and its output shaft drives the first pulley 4 to rotate. The first pulley 4, via a belt, drives the second pulley 5 and the first stirring rod 11 to rotate. The first bevel gear 16 at the bottom of the first stirring rod 11 drives the second bevel gear 12 to rotate, which in turn drives the third bevel gear 17, which meshes with the second bevel gear 12, to rotate. Since the third bevel gear 17 is fixed to the top of the second stirring rod 15, it causes the second stirring rod 15 to rotate in the opposite direction to the first stirring rod 11, thereby improving the mixing and sterilization effect.

[0044] Meanwhile, as the first stirring rod 11 rotates, its reciprocating thread 18 and the steel ball 20 embedded in the fixing block 19 form a ball screw pair, causing the first stirring rod 11 to generate up-and-down reciprocating linear motion while rotating. This, in turn, drives the second stirring rod 15 to move up and down in a synchronized linear motion through the protective shell 1401, causing the connecting rod 14 to slide on the surface of the guide rod 13. This forms a multi-dimensional stirring that combines radial and axial forces, significantly improving the mixing effect and sterilization efficiency, and making it more suitable for practical application.

[0045] After the mixed sterilization is completed, the solenoid valve 25 is opened, and the water in the treatment tank 1 flows into the installation box 10 below through the drain outlet 26. The water flows through the filter plate 24 and the dust-absorbing cotton 23 in sequence, and the solid impurities are filtered out. The clean water passes through the through holes on the movable plate 22 and is finally discharged from the outlet 9.

[0046] After the drainage is completed, the solenoid valve 25 is closed. During the initial mixing and sterilization stage of the next batch processing (at this time there is no clean water in the tank), the up-and-down reciprocating motion of the second stirring rod 15 will push the movable rod 8 up and down through the connecting block 21, thereby driving the movable plate 22 to move up and down in the mounting box 10, and periodically squeezing the dust-absorbing cotton 23 located on it.

[0047] This squeezing action forces the pure water remaining in the pores of the vacuum cotton 23 out and discharges it through the water outlet 9. This process effectively recovers the pure water remaining in the filter medium, avoids water waste, and prevents secondary pollution caused by the growth of microorganisms in stagnant residual water.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
