Description

Technical Field

[0001] The present invention belongs to the technical field of direct drinking water purification and sterilization equipment, and in particular relates to direct drinking water purification and sterilization equipment and a sterilization method. Background Art

[0002] Direct drinking water, also known as healthy living water, refers to water that is directly drinkable and has no pollution, no degradation, meets the physiological needs of the human body (contains beneficial mineral elements similar to the human body), and has a weakly alkaline pH value. Although tap water is treated by the water plant before being delivered to the user's home for use, tap water contains a large amount of ions such as calcium, magnesium, copper, etc., and may contain bacteria and microorganisms that have not been completely removed. Drinking it directly will affect people's health. Therefore, it is generally necessary to use purification and sterilization equipment to purify the tap water, thereby improving the quality of the tap water to meet the direct drinking standard.

[0003] Existing purification and sterilization equipment mainly uses ultraviolet light generated by ultraviolet sterilizers to purify and sterilize tap water. When the ultraviolet sterilizer purifies and sterilizes tap water, due to the short length of the ultraviolet sterilizer cylinder, the time for water to pass through the ultraviolet sterilizer cylinder is short, which makes the ultraviolet sterilizer have a poor sterilization effect on tap water; in addition, during long-term use, since there are generally multiple ultraviolet sterilization lamps in the ultraviolet sterilizer, the flow rate will decrease when the water flows through the position between multiple ultraviolet sterilization lamps, so that impurities in the water are easily gathered on the outer sleeve of the ultraviolet sterilization lamp, which makes the ultraviolet light emitted by the ultraviolet sterilization lamp easily blocked by impurities, which will also affect the sterilization effect of the ultraviolet sterilization lamp on tap water.

[0004] Therefore, it is necessary to invent a direct drinking water purification and sterilization device and a sterilization method to solve the above problems. Summary of the invention

An ultraviolet germicidal lamp 14 is plugged into the open end of the second sleeve 13. A plug 15 and an end cover 16 are respectively provided at both ends of the ultraviolet germicidal lamp 14. The plug 15 and the end cover 16 are respectively threadedly connected with two sealing plates 2. A plurality of second sleeves 13 are slidably sleeved with a cleaning assembly. An adjusting rod 17 is inserted through a vertical thread at the center of the cleaning assembly. One end of the adjusting rod 17 is vertically rotatably connected to the sealing plate 2 with the end cover 16 installed. The other end of the adjusting rod 17 is rotatably connected to the sealing plate 2 with the end cover 16 installed. The first fixing ring 9 and the second fixing ring 10 are respectively located on the side where the water inlet hole 7 and the water outlet hole 8 are separated, and the bottom end of the water inlet flange pipe 3 is opposite to the area between the first fixing ring 9 and the second fixing ring 10, and the water outlet flange pipe 4 is located on the side where the first fixing ring 9 and the second fixing ring 10 are away from each other;

[0036] The sealing assembly includes a sealing strip 22, and the sealing strip 22 is of hollow design. The sealing strip 22 is located at the bottom of the strip plate 12, and the sealing strip 22 can cover the bottoms of multiple drainage holes at the same time. The top of the sealing strip 22 is fixedly connected with multiple cross-shaped limiting rods 23, and the multiple limiting rods 23 are slidably inserted in the multiple drainage holes one by one, and the length and width of the limiting rods 23 match the length and width of the drainage holes respectively. The top of the limiting rod 23 is fixedly connected with a cross-shaped limiting plate 24 with the same shape as the limiting rod 23, and the length and width of the limiting plate 24 are both greater than the length and width of the drainage hole. The length of the limiting rod 23 is greater than the thickness of the strip plate 12, and the sum of the gravity of the multiple limiting rods 23 and the multiple limiting plates 24 is less than the buoyancy generated by the sealing plate 2;

[0037] Before using the present invention, first install the first sleeve 5, the second sleeve 13 and the ultraviolet germicidal lamp 14 into the ultraviolet germicidal tube 1, then install the sealing plate 2 and use the plug 15 and the end cover 16 to fix the first sleeve 5, the second sleeve 13 and the ultraviolet germicidal lamp 14, then connect the wire 21 on the ultraviolet germicidal lamp 14 with the controller 20, and after the connection is completed, connect the water inlet flange pipe 3 and the water outlet flange pipe 4 to the water inlet end and the water outlet end of the water supply pipeline respectively, and turn on the controller 20;

[0038] When the present invention is used, as the tap water flows into the ultraviolet disinfection cylinder 1 through the water inlet flange pipe 3, the tap water can flow along the upper half of the first sleeve 5 toward the direction of the water outlet flange pipe 4 under the obstruction of the two arc plates 11 and the two strip plates 12. When the tap water flows into the water inlet hole 7, the tap water can enter the first sleeve 5 through the water inlet hole 7. Since the two ends of the first sleeve 5 are blocked by the two sealing plates 2, the tap water entering the first sleeve 5 can flow along the inside of the first sleeve 5 toward the direction of the water inlet flange pipe 3. When the tap water flows to the water outlet hole When the ultraviolet sterilizing tube 1 is in position 8, the tap water can flow into the bottom inner wall of the ultraviolet sterilizing tube 1 through the water outlet hole 8, and then the tap water can flow toward the water outlet flange pipe 4 again under the restriction of the two strip plates 12 and the two arc plates 11. Then, as the water level in the ultraviolet sterilizing tube 1 continues to rise, the tap water can flow out of the ultraviolet sterilizing tube 1 through the water outlet flange pipe 4. In this process, the ultraviolet sterilizing lamp 14 can perform three sterilization operations on the tap water, thereby greatly improving the sterilization effect of the ultraviolet sterilizing lamp 14 on the tap water compared with the existing one-time sterilization operation.

[0039] In the process of sterilizing tap water of the present invention, as the ultraviolet sterilizing cylinder 1 is filled with tap water, the sealing strip 22 can seal the drainage hole from the bottom of the strip plate 12 under the action of its own buoyancy, so that the tap water entering the ultraviolet sterilizing cylinder 1 can be sterilized three times in the above manner;

[0040] During long-term use, impurities in the water are easily attached to the outer wall of the second sleeve 13, thereby affecting the sterilization effect of the ultraviolet germicidal lamp 14. At this time, the hand wheel 18 can be used to drive the adjustment rod 17 to rotate. As the adjustment rod 17 rotates, the cleaning component can clean the outer wall of the second sleeve 13 and the inner wall of the first sleeve 5 along the inside of the first sleeve 5, thereby ensuring the light transmittance of the first sleeve 5 and the second sleeve 13, and further ensuring the sterilization effect of the ultraviolet germicidal lamp 14 on tap water;

[0041] When the cleaning is completed, first close the external water supply pipeline, then open the drain valve 19 to release the cleaned sewage. As the water level in the ultraviolet sterilization tube 1 gradually decreases, when the water level is lower than the bottom of the strip plate 12, the sealing strip 22 can move downward under the action of gravity, and the drainage hole is opened at this time, so that the sewage located on the top of the strip plate 12 can flow smoothly downward through the drainage hole. When the sewage in the ultraviolet sterilization tube 1 is drained, close the drain valve 19 and open the external water supply pipeline to fill the ultraviolet sterilization tube 1 with clean water, then close the external water supply pipeline again and open the drain valve 19, so as to realize the flushing operation of the first sleeve 5 and the second sleeve 13. After the flushing is completed, close the drain valve 19 and restore the external water supply pipeline.

[0042] like Figure 5 and Figure 6 As shown, the cleaning assembly includes a circular cleaning disc 25, and a plurality of through holes are formed between the two sides of the cleaning disc 25. The cleaning disc 25 is slidably sleeved on the plurality of second sleeves 13, and the adjusting rod 17 is threadedly inserted and inserted at the center of the cleaning disc 25. The positions on both sides of the cleaning disc 25 that are opposite to the second sleeves 13 are fixedly connected with convex rings 26, and the convex rings 26 are sleeved on the periphery of the corresponding second sleeves 13. The inner side of the port of the convex ring 26 is fixedly connected with a first rubber cleaning ring 27, and the inner side of the first rubber cleaning ring 27 is fitted with the outer wall of the second sleeve 13. The outer side of the cleaning disc 25 is fixedly sleeved with a second rubber cleaning ring 28, and the outer side of the second rubber cleaning ring 28 is fitted with the inner wall of the first sleeve 5.

[0043] In the process of ultraviolet sterilization of tap water of the present invention, after the tap water enters the first sleeve 5, due to the small gaps between the plurality of second sleeves 13, impurities in the water are easily attached to the outer wall of the second sleeve 13 during long-term use, thereby affecting the sterilization effect of the ultraviolet germicidal lamp 14. At this time, by providing a cleaning disk 25, when the light transmittance of the second sleeve 13 decreases, the external water supply pipeline is first closed, and then the adjusting rod 17 is driven to rotate by the hand wheel 18. As the adjusting rod 17 rotates, the cleaning disk 25 can be moved on the adjusting rod. 17 is driven to move along the inside of the second sleeve 13. During this process, the first rubber cleaning ring 27 in the end of the convex ring 26 can scrape against the surface of the second sleeve 13, so as to scrape off the impurities attached to the surface of the second sleeve 13 from the second sleeve 13. In addition, since the convex ring 26 and the first rubber cleaning ring 27 are provided on both sides of the cleaning disk 25, as the cleaning disk 25 moves, the first rubber cleaning rings 27 on both sides of the cleaning disk 25 can perform two scraping operations on the surface of the second sleeve 13, thereby improving the cleaning effect on the surface of the second sleeve 13.

[0044] At the same time, during the movement of the cleaning disc 25, the second rubber cleaning ring 28 located on the outside of the cleaning disc 25 can perform a scraping operation along the inner wall of the first sleeve 5, thereby cleaning the inner wall of the first sleeve 5 and ensuring the light transmittance of the first sleeve 5, thereby improving the sterilization effect of the ultraviolet sterilization lamp 14 on tap water through the first sleeve 5 and the second sleeve 13, and in the above cleaning process, the cleaning disc 25 can be moved back and forth multiple times, thereby improving the cleaning effect of the first rubber cleaning ring 27 and the second rubber cleaning ring 28 on the second sleeve 13 and the first sleeve 5.

[0045] like Figure 3 , Figure 7 and Fig. 9 As shown, a plurality of scraping strips 29 are distributed in an annular manner on the periphery of the first sleeve 5, and a connecting ring 30 is fixedly connected between the two ends of the plurality of scraping strips 29, and the two connecting rings 30 are respectively rotatably sleeved on the positions near the two ends of the first sleeve 5, and a rotating ring 31 is fixedly connected between the plurality of scraping strips 29, and the rotating ring 31 is rotatably mounted on the inner side of the first fixed ring 9, and the rotating ring 31 and the first sleeve 5 are rotatably connected, and a narrow and long notch matching the length of the strip plate 12 is provided on the side of the strip plate 12 close to the first sleeve 5, and the width of the notch matches the thickness of the scraping strip 29, and the water flow at the notch is less than the water flow of the water inlet hole 7 and the water outlet hole 8, and a spiral long strip blade 32 is fixedly connected between two adjacent scraping strips 29, and the blade 32 is located on the side of the first fixed ring 9 away from the second fixed ring 10, and the width of the blade 32 is equal to the vertical distance from the outer side of the first sleeve 5 to the inner wall of the ultraviolet sterilization tube 1, and the head and tail parts of the two adjacent blades 32 overlap in different planes;

[0046] By providing the scraper strips 29, when the water in the first sleeve 5 flows toward the outlet flange pipe 4 through the water outlet, the water flow can impact the blades 32 located in the bottom area of ​​the strip plate 12, and then the spiral blades 32 can drive the multiple scraper strips 29 to scrape around the outer wall of the first sleeve 5 under the impetus of the water flow. When the multiple scraper strips 29 rotate around the outside of the first sleeve 5, when the scraper strips 29 move to the position of the strip plate 12, the scraper strips 29 can continue to rotate through the narrow notch of the strip plate 12 close to the side of the first sleeve 5, thereby ensuring that the scraper strips 29 will not be blocked by the strip plate 12, and as the scraper strips 29 scrape along the outer wall of the first sleeve 5, impurities attached to the outer wall of the first sleeve 5 can be scraped off by the scraper strips 29, thereby ensuring the cleanliness of the outer wall of the first sleeve 5, and further ensuring the sterilization effect of the ultraviolet germicidal lamp 14 on tap water through the first sleeve 5.

[0047] like Figure 5 As shown, rubber washers 33 are provided on opposite sides of the two sealing plates 2, and the two rubber washers 33 are respectively fitted with the two ends of the first sleeve 5; after the rubber washers 33 are installed into the ultraviolet sterilization tube 1, as the two sealing plates 2 are installed at the two ends of the ultraviolet sterilization tube 1, the rubber washers 33 can protect the two ends of the first sleeve 5 to prevent the two ends of the first sleeve 5 from colliding with the sealing plates 2.

[0048] like Fig.10 As shown, a plurality of rubber protective rings 34 are evenly sleeved on the ultraviolet germicidal lamp 14, and the outer sides of the rubber protective rings 34 are in contact with the inner walls of the second sleeve 13. By providing the rubber protective rings 34, when the ultraviolet germicidal lamp 14 is installed into or removed from the second sleeve 13, the rubber protective rings 34 can protect the outer sides of the ultraviolet germicidal lamp 14, thereby preventing the ultraviolet germicidal lamp 14 or the second sleeve 13 from being damaged due to collisions during the disassembly process.

[0049] The present invention also provides a sterilization method using a direct drinking water purification and sterilization device, the method comprising the following steps:

[0050] Step 1: Connect the water inlet flange pipe 3 and the water outlet flange pipe 4 of the ultraviolet sterilization cylinder 1 to the water inlet end and the water outlet end of the water supply pipeline respectively, and allow water to flow into the ultraviolet sterilization cylinder 1 through the water inlet flange pipe 3, and then turn on the controller 20;

[0051] Step 2: After the water flows into the ultraviolet sterilization tube 1, the water flows along the upper part of the ultraviolet sterilization tube 1 first, and enters the first sleeve 5 through the water inlet pipe, and then the water flows into the first sleeve 5 through the water outlet hole 8 to the lower part of the ultraviolet sterilization tube 1 and finally flows out through the water outlet flange pipe 4, thereby completing three flow operations and increasing the sterilization time of the water by the ultraviolet sterilization lamp 14;

[0052] Step 3: After a period of sterilization operation, close the water supply pipeline, and then turn the hand wheel 18 to drive the cleaning component to clean the first sleeve 5 and the second sleeve 13;

[0053] Step 4: After cleaning is completed, open the drain valve 19 to discharge the cleaned sewage from the drain valve 19;

[0054] Step 5: When the sewage is completely drained, close the sewage valve 19 and reopen the water supply pipeline.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
