Description

TECHNICAL FIELD

[0001] The present application relates to composite sterilization technology, in particular to a mineral water processing series composite sterilization treatment system. BACKGROUND

[0002] It is known that mineral water needs to go through water taking, filtering, disinfection and packaging in the production process, and the disinfection step is the focus of production. The disinfection methods commonly used are ultraviolet (over-flow type ultraviolet sterilizer), ozone (micro-nano ozone bubbles) and high-efficiency activated carbon, which do not have chemical residues and are suitable for food-grade disinfection and sterilization.

[0003] For example, the application publication No. CN105293622B, application publication date is March 27, 2018, and the name is "a punch forming over-flow type ultraviolet disinfection device", which includes a disinfection device, including a main body provided with a water inlet and a water outlet provided with a water inlet device and a water outlet device; each end of the main body is provided with a structure symmetrical end head, the end head is a punch forming end head, the end head is provided with a plurality of uniformly distributed reference tables, each reference table is provided with a through hole, and each reference table is provided with a wire head for setting a sealing sleeve through welding; the ultraviolet lamp sleeve is arranged on the two reference tables symmetrically arranged on the two end heads; the distribution box is connected with the ultraviolet lamp sleeve, and is arranged below the main body through the barrel support. The disinfection device manufacturing process includes one-time punch forming and secondary punch forming of the end head, end head spinning forming, water inlet and water outlet punch forming, welding, assembly and other steps. Through the above design, the disinfection device realizes batch production, improves the quality of the equipment, reduces the production cost, and is beneficial to the later maintenance.

[0004] The existing technology has the following disadvantages: when the mineral water is deeply treated, the ultraviolet, high-efficiency activated carbon and micro-nano ozone bubbles are combined in series to carry out composite sterilization and filtration on the mineral water to ensure the quality of the mineral water. The ultraviolet sterilization includes UVC (short-wave ultraviolet) and UVA (long-wave ultraviolet), and when the UVA ultraviolet catalyzes the micro-nano ozone bubbles, the water flow is limited based on the over-flow type ultraviolet sterilizer. However, the high-concentration micro-nano ozone bubbles are easily adsorbed on the glass cover of the ultraviolet lamp during the movement with the water flow, which affects the catalysis of the UVA ultraviolet lamp on the micro-nano ozone bubbles.

DETAILED DESCRIPTION

[0033] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0034] Please refer to Figures 1-10 The embodiment of the present application provides a technical scheme: a mineral water processing series composite sterilization treatment system, comprising a UVC sterilizer 1, a plurality of micro-nano sterilizers 2 and a high-efficiency activated carbon sterilization filter 3 connected in sequence, all of which comprise a catalytic pipe 11, a bottom bin 12 and a top bin 13, the top bin 13 is fixedly connected with a water outlet pipe 16, the water outlet pipe 16 is connected with the bottom bin 12 of the next sterilizer in series, the bottom bin 12 is rotatably connected with a composite drive flow paddle 15, the number of micro-nano sterilizers 2 is 2-8, the UVC sterilizer 1 is used as the first sterilization equipment in series, and the mineral water is pumped into the bottom bin 12 of the UVC sterilizer 1 by a water pump.

[0035] The catalytic pipe 11 of the UVC sterilizer 1 is provided with a UVC lamp 14, the UVC lamp 14 is a short-wave ultraviolet lamp, and the purpose is to kill bacteria in the mineral water by short-wave ultraviolet rays, so as to achieve the effect of water purification, and the composite drive flow paddle 15 in the bottom bin 12 of the UVC sterilizer 1 is driven to rotate to assist the flow of mineral water into the catalytic pipe 11.

[0036] The bottom bin 12 of the micro-nano sterilizer 2 is provided with a bubble generator 26 for outputting micro-nano ozone bubbles for sterilizing the mineral water. The catalytic tube 11 of the micro-nano sterilizer 2 is provided with a UVA lamp tube 23 which is a long-wave ultraviolet lamp. The long-wave ultraviolet light can catalyze the micro-nano ozone bubbles to break, increase the sterilization effect of the micro-nano ozone bubbles, and has the ability to remove odor. The composite flow driving paddle 15 includes a middle outlet pipe 152 and an inner paddle plate 154 arranged in the middle outlet pipe 152. The middle outlet pipe 152 is arranged vertically in the bottom bin 12 of the micro-nano sterilizer 2. The UVA lamp tube 23 extends into the middle outlet pipe 152, and a brewing channel is formed between the two, so that part of the mineral water output along the middle outlet pipe 152 is compressed and the flow rate is increased along the brewing channel. The bubbles attached to the UVA lamp tube 23 are washed to reduce the amount of attachment, thereby enhancing the catalytic efficiency. Another part of the mineral water directly mixes with the micro-nano ozone bubbles and then enters the catalytic tube 11. The flowing mineral water can also stir this part to produce a mixed flow, so that more bubbles are irradiated by the UVA lamp tube 23, further enhancing the catalytic efficiency. Figure 5 The UVA lamp tube 23 extends into the middle outlet pipe 152, and a brewing channel is formed between the two, so that part of the mineral water output along the middle outlet pipe 152 is compressed and the flow rate is increased along the brewing channel. The bubbles attached to the UVA lamp tube 23 are washed to reduce the amount of attachment, thereby enhancing the catalytic efficiency. Another part of the mineral water directly mixes with the micro-nano ozone bubbles and then enters the catalytic tube 11. The flowing mineral water can also stir this part to produce a mixed flow, so that more bubbles are irradiated by the UVA lamp tube 23, further enhancing the catalytic efficiency.

[0037] The catalytic tube 11 of the high-efficiency activated carbon sterilization filter 3 is provided with an activated carbon sterilization rod 31 which is stacked by a plurality of high-efficiency activated carbon rings. The activated carbon sterilization rod 31 is used to filter the remaining solid particle impurities in the mineral water and catalyze and absorb the residual ozone to reduce the content of residual micro-nano ozone bubbles in the sterilized mineral water.

[0038] The top of the bottom bin 12 of the micro-nano sterilizer 2 and the high-efficiency activated carbon sterilization filter 3 are both provided with a guide plate 25 which is a circular ring with a slope to guide the liquid into the catalytic tube 11.

[0039] In another embodiment of the present invention, multiple bottom chambers 12 are each provided with an inlet 121 tangential to the inner wall, allowing the liquid entering the bottom chamber 12 to flow along the inner wall of the bottom chamber 12. When mineral water enters the micro-nano sterilizer 2, the mineral water flowing along the inner wall of the bottom chamber 12 will generate a swirling flow, causing the micro-nano ozone bubbles and mineral water to mix. The top chamber 13 of the micro-nano sterilizer 2 is provided with an outlet pipe 16 leading to the next container. A diversion pipe 161 is fixedly connected between the bottom chamber 12 of the micro-nano sterilizer 2 and the outlet pipe 16. When the bubble generator 26 generates micro-nano ozone bubbles, it will generate large normal bubbles. These normal bubbles will rise quickly and are large in size. The micro-nano ozone bubbles cause a higher bubble content in the first micro-nano sterilizer 2 (only the first micro-nano sterilizer 2 has a bubble generator 26). The large normal bubbles will block (reflection, refraction, etc.) the ultraviolet rays emitted by the UVA lamp tube 23. At this time, some of the mineral water mixed with micro-nano ozone bubbles enters the outlet pipe 16 ahead of time along the diversion pipe 161 of the bottom chamber 12 of the micro-nano sterilizer 2, and reaches the next micro-nano sterilizer 2. This reduces the time that part of the mineral water and the large normal bubbles coexist, and enhances the catalytic efficiency. The large bubbles burst in the top chamber 13 after rising, and the waste gas is recovered.

[0040] Preferably, an outer paddle plate 151 is provided on the outside of the outlet pipe 152, such as... Figure 5 As shown, the outer paddle plate 151 delivers liquid to the bottom as the middle outlet pipe 152 rotates, so as to promote the mineral water mixed with micro-nano ozone bubbles to be transported to the bottom chamber 12 of the micro-nano sterilizer 2, so that part of the mineral water mixed with micro-nano ozone bubbles flows along the diversion pipe 161 to the outlet pipe 16 for mixing.

[0041] Preferably, the bottom chamber 12 of the micro-nano sterilizer 2 is provided with a limiting spiral plate 21, such as... Figure 5 As shown, an upward channel is formed between the limiting spiral plate 21 and the outer paddle plate 151. The length of the upward channel is between 3mm and 7mm. The cross-section of the limiting spiral plate 21 is inclined. When large-sized bubbles are pushed to the bottom of the bottom chamber 12 of the micro-nano sterilizer 2 by the outer paddle plate 151, they can float up along the limiting spiral plate 21. However, micro-nano ozone bubbles do not float easily. When water enters through the inlet 121, it will fill the bottom chamber 12 to increase the mineral water pressure at the limiting spiral plate 21, causing the mineral water mixed with micro-nano ozone bubbles to enter the diversion pipe 161.

[0042] In another embodiment of the present invention, a coupling 18 is rotatably connected to the bottom of the bottom chamber 12. The coupling 18 is connected to a drive unit (which can be a motor and a reducer). A composite propeller 15 is disposed on the coupling 18. An opening leading to the outlet pipe 152 is provided on the coupling 18. When the coupling 18 is located in the bottom chamber 12 of the micro-nano sterilizer (e.g.) Figure 5As shown in FIG. 1, the mineral water entering the bottom compartment 12 of the UVC sterilizer 1 will flow into the middle outlet pipe 152 through the opening, and be driven by the inner paddle 154 in the middle outlet pipe 152 to flow along the brewing channel.

[0043] In another embodiment of the present application, the bottom compartment 12 of the UVC sterilizer 1 is provided with a coarse-hole active filter plate 17 and an inverted middle outlet pipe 152, as shown in FIG. 2. Figure 3 As shown in FIG. 2, the middle outlet pipe 152 is inverted, and the outer paddle 151 of the middle outlet pipe 152 is arranged at the top and transports the mineral water to the catalytic pipe 11 of the UVC sterilizer 1 as the middle outlet pipe 152 rotates. The water inlet 121 on the bottom compartment 12 of the UVC sterilizer 1 is located below the coarse-hole active filter plate 17, so that the mineral water entering the bottom compartment 12 of the UVC sterilizer 1 will be filtered by the coarse-hole active filter plate 17 (which is made of high-efficiency activated carbon). The opening of the coupling 18 has the ability to output liquid when it is located in the bottom compartment 12 of the UVC sterilizer 1, thereby agitating the mineral water in the bottom compartment 12 of the UVC sterilizer 1, reducing the deposition of impurities, and making the impurities suspended and filtered by the coarse-hole active filter plate 17.

[0044] In another embodiment of the present application, the composite flow-driving paddle 15 in the bottom compartment 12 of the high-efficiency activated carbon sterilization filter 3 is upright, as shown in FIG. 3. Figure 6 As shown in FIG. 3, the bottom compartment 12 of the high-efficiency activated carbon sterilization filter 3 is provided with a middle outlet pipe 152, and the middle outlet pipe 152 is provided with an outer paddle 151. The outer layer of the outer paddle 151 is provided with a partition plate 32. The bottom compartment 12 of the high-efficiency activated carbon sterilization filter 3 is not provided with a shunt pipe 161, and is in a closed state. The mineral water driven by the outer paddle 151 is output into the middle outlet pipe 152, so as to increase the flow rate of the liquid output by the middle outlet pipe 152 and accelerate the mineral water passing through the activated carbon sterilization rod 31 with resistance. The partition plate 32 blocks the backflow of the liquid entering the bottom, so that the mineral water driven by the outer paddle 151 can only be output from the middle outlet pipe 152.

[0045] In another embodiment of the present application, the top compartment 13 of the UVC sterilizer 1 is provided with a separation mechanism 4. The separation mechanism 4 can be arranged on the top compartment 13 of the first UVC sterilizer 1 or the top compartment 13 of the first two UVC sterilizers 1, and does not need to be arranged on the top compartment 13 of each UVC sterilizer 1. The separation mechanism 4 comprises a secondary cover 22 rotatably connected in the top compartment 13, as shown in FIG. 4. Figure 4 As shown in FIG. 4, the secondary cover 22 is provided with a coupling ring 222 extending out of the top compartment 13. The coupling ring 222 is drivingly coupled with a driving source 24 (which can be a motor or a motor cooperating with a speed reducer), so as to rotate the secondary cover 22. When rotating, the liquid moves to the inner wall of the secondary cover 22 due to the inertial centrifugal force. The large-size gas bubbles floating up and the micro-nano ozone gas bubbles breaking at the water surface will generate gas. After the water body moves along the two sides, the gas will converge along the axis, so as to facilitate the recovery of waste gas.

[0046] Preferred, such as Figure 4 As shown, the inner wall of the sub-distribution hood 22 is provided with a high position and a low position. A liquid outlet trough 221 is opened at the low position. A liquid outlet channel is formed between the top chamber 13 of the UVC sterilizer 1 and the sub-distribution hood 22. As the sub-distribution hood 22 rotates, the liquid will enter the liquid outlet trough 221 at the low position and then enter the liquid outlet channel. As the outer wall of the sub-distribution hood 22 rotates, it will accelerate into the water outlet pipe 16, increasing the flow rate and pressure entering the water outlet pipe 16.

[0047] In another embodiment of the present invention, a pressure relief port 153 is provided on the outlet pipe 152. Because of the rounded corners on the pressure relief port 153, the inner wall opening of the pressure relief port 153 is smaller than the outer wall opening. When the pressure relief port 153 is in the UVC sterilizer 1, such as Figure 3 As shown, a portion of the mineral water enters the bottom chamber 12 in advance to contact the coarse-pore activated filter plate 17 for filtration. When the pressure relief port 153 is in the micro-nano sterilizer 2, as... Figure 5 As shown, due to the limitation of the brewing channel, the internal liquid can be discharged from the pressure relief port 153 into the bottom chamber 12 when the pressure is high, assisting in the mixing of micro-nano bubbles and mineral water. When the pressure relief port 153 is in the high-efficiency activated carbon sterilization filter 3, such as... Figure 6 As shown, the mineral water that quickly passes through the pressure relief port 153 will carry the mineral water in the bottom tank 12 into the tank, increasing the output flow of the middle outlet pipe 152.

[0048] First, the mineral water is pumped into the bottom chamber 12 of the UVC sterilizer 1 and pre-filtered by the coarse-pore active filter plate 17. Then, it is sterilized by short-wave ultraviolet light emitted by the UVC lamp tube along the catalytic tube 11 of the UVC sterilizer 1. After sterilization, the mineral water enters the bottom chamber 12 of the first micro-nano sterilizer 2 along the top chamber 13 of the UVC sterilizer 1.

[0049] The mineral water mixed with the bubble generator 26 in the bottom chamber 12 of the first micro-nano sterilizer 2 emits micro-nano ozone bubbles. At this time, some mineral water mixed with normal bubbles and micro-nano bubbles enters the catalytic tube 11 of the micro-nano sterilizer 2 and is irradiated by the UVA lamp tube for sterilization. At the same time, the liquid out of the middle outlet pipe 152 washes the glass tube on the outer wall of the UVA lamp tube along the rinsing channel. After the mineral water entering the catalytic tube 11 flows to the top, it is separated from the broken bubbles by the rotation of the sub-distribution hood 22 and enters the next sterilizer through the inlet 121. Meanwhile, another part of the mineral water mixed with micro-nano bubbles (and a small amount of normal bubbles, because normal bubbles will float and are not easy to be pumped away) is restricted by the outer paddle 151 and transported to the bottom chamber 12 of the next micro-nano sterilizer 2 for continued sterilization.

[0050] The last micro-nano sterilizer 2 outputs mineral water to the high-efficiency activated carbon sterilization filter 3, so that it passes through the activated carbon sterilization rod 31 to complete the composite sterilization work.

[0051] Certain exemplary embodiments of the present application have been described above by way of illustration, and it is to be understood that certain modifications can be made without departing from the spirit and scope of the application as set forth in the claims. Accordingly, the above description and drawings are to be construed in an illustrative, and not a restrictive, sense.
