Description

Technical Field

[0001] The present invention relates to the field of water treatment, and particularly to a pressurized ozone disinfection device. Background Art

[0002] As is well known, ozone has relatively active chemical properties and strong oxidizing properties, which makes its application fields relatively wide, especially in the field of water resource purification, specifically involving the disinfection of civil water, industrial water, sewage, wastewater or other types of water. When disinfecting water bodies, ozone is transported into the water bodies through a delivery pump. Relying on the strong oxidizing property of ozone, harmful substances in the water bodies can be killed.

[0003] For example, in a Chinese patent document with the authorization announcement number CN209122956U, the announcement date of July 19, 2019, and the name "A Pressurized Ozone Disinfection and Cleaning Pool", it includes a clean water pipeline for introducing clean water and a gas pipeline for introducing ozone. The clean water pipeline includes an inlet coiled pipe arranged along the rectangular surface of the pool body and several outlet pipes vertically connected to the inlet coiled pipe. A spherical connector is provided at the joint of the inlet coiled pipe and the outlet pipes; the gas pipeline includes an intake coiled pipe, which is arranged above the inlet coiled pipe and parallel to the inlet coiled pipe; it also includes a vertical connecting pipe for connecting the inlet coiled pipe and the intake coiled pipe. The spherical connector is also provided with a ventilation hole connected to the vertical connecting pipe; it also includes a high-pressure pump, and the high-pressure pump communicates with the gas pipeline. The utility model improves the flushing disinfection water with fast flow rate and high pressure while injecting ozone, and improves the disinfection effect.

[0004] The disadvantages of the above prior art are that by setting multiple outlet pipes branched on the inlet pipe to increase the action range of ozone, but when the power of the delivery pump remains unchanged, increasing the number of outlet pipes will undoubtedly reduce the pressure inside each outlet pipe, making it impossible to transport ozone to deeper water layers.

[0037] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] In the description of the present invention, it is to be understood that Figure 10 The position of the first spring 10 relative to the abutment block 9 is on the left, and vice versa. The terms "center", "length", "width", "degree", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0039] Reference Figures 1-12 A pressurized ozone disinfection device provided in an embodiment of the present invention is used to disinfect water bodies by using ozone. The device comprises an outlet pipe 1 for conveying ozone, and a transfer pipe 2 is rotatably sealed on the outlet pipe 1. The outlet of the transfer pipe 2 is not coaxially arranged with the outlet pipe 1, so that when ozone is discharged from the transfer pipe 2, its reaction force drives the transfer pipe 2 to rotate around the central axis of the outlet pipe 1.

[0040] Specifically, ozone can be stored in a container, which is transported by a booster pump, that is, a connecting pipe is provided at the outlet of the container, a main pipe 25 is provided on the output port of the booster pump, and the connecting pipe is connected to the main pipe 25 through the booster pump, and the main pipe 25 is connected to a plurality of outlet pipes 1. When disinfecting a water body (which can be civil water, industrial water, sewage, wastewater or other water), the end of the outlet pipe 1 is vertically or horizontally inserted into the water body, and the ozone in the container is transported to various positions in the water body through the plurality of outlet pipes 1 by the booster pump, so as to disinfect the water body by the strong oxidizing property of ozone. This is a prior art and will not be described in detail (for details, see the patent document with the authorization announcement number CN209122956U). The embodiment of the present invention One of the core innovations is that a transfer tube 2 is rotatably sealed on the air outlet pipe 1, and the transfer tube 2 includes a vertical section 201, a first horizontal section 202 and a second horizontal section 203, and the three are perpendicular to each other, and a convex ring or other limiting structure is provided between the air outlet pipe 1 and the vertical section 201 to prevent the two from detaching from each other. The air outlet of the transfer tube 2 is not coaxially arranged with the air outlet pipe 1, and is preferably arranged horizontally or obliquely downward, so that when ozone is discharged from the transfer tube 2, its reaction force drives the transfer tube 2 itself to rotate around the central axis of the air outlet pipe 1, so that the ozone is ejected along the tangential direction of its movement stroke. Therefore, this method can increase the range of action of ozone while reducing the number of air outlet pipes 1, thereby indirectly increasing the pressure when ozone is added.

[0041] Furthermore, a dispersion disk 3 is fixedly connected inside the transfer tube 2, and a plurality of through holes 4 are formed on the dispersion disk 3. Specifically, the dispersion disk 3 is in the shape of a disk that matches the internal space of the second horizontal section 203, and the dispersion disk 3 is coaxially arranged with the second horizontal section 203. The effect of such arrangement is that the ozone entering the water body through the transfer tube 2 can be divided into multiple streams through the dispersion disk 3, so that a plurality of small bubbles are generated in the water body, so as to increase the contact area between the ozone and the water body, thereby improving the efficiency of disinfection.

[0042] Further, a passive adjustment mechanism for adjusting the conduction area of the through holes 4 is provided on the dispersion disc 3. The passive adjustment mechanism includes a plurality of blocking rods 5, and the positions of the plurality of blocking rods 5 are arranged corresponding to the positions of the plurality of through holes 4; the blocking rod 5 has a first position for partially blocking the through hole 4 and a second position for completely conducting the through hole 4. Specifically, the through holes 4 have multiple columns, and the plurality of blocking rods 5 are arranged corresponding to the positions of the multiple columns of through holes 4. When the blocking rod 5 is in the first position, the plurality of blocking rods 5 respectively have overlapping parts with the multiple columns of through holes 4 to partially block the through holes 4. When the blocking rod 5 is in the second position, the plurality of blocking rods 5 are completely away from the multiple columns of through holes 4 to completely conduct the through holes 4. The effect of such a setting is that when the pressure inside the adapter pipe 2 is at a normal value, the blocking rod 5 is located between the first position and the second position, that is, the blocking rod 5 does not completely conduct the through hole 4, but there is also no more part of the through hole 4 blocked when the blocking rod 5 is in the first position (for the convenience of description, the blocking rod 5 in this state is called the third position). At this time, ozone can be normally delivered to the water body. When the power of the booster pump becomes larger, the blocking rod 5 is switched from the third position (as shown in Figure 6c shown) to the second position (as shown in Figure 6b shown). At this time, the through holes 4 are completely opened, so as to reduce the pressure of the gas output from the adapter pipe 2. When the power of the booster pump becomes smaller, the blocking rod 5 is switched from the third position to the first position. At this time, the area blocked by the blocking rod 5 for the through hole 4 is increased, so that the conduction area of the through hole 4 becomes smaller, so as to increase the pressure of the gas output from the adapter pipe 2, so as to maintain the constancy of the gas output pressure of the adapter pipe 2 as much as possible.

[0043] Preferably, the width of the blocking rod 5 is smaller than the radial dimension of the through hole 4. Specifically, when the blocking rod 5 is in the first position, the plurality of blocking rods 5 are respectively located in the middle positions of the multiple columns of through holes 4 (as shown in Figure 6a shown). At this time, each through hole 4 is divided into two left and right passing areas, which corresponds to the state when the pressure inside the adapter pipe 2 is relatively small. The advantages of such a setting are as follows: First, it further reduces the conduction area of the through hole 4 to increase the output pressure of ozone. Second, the number of strands of ozone is doubled, so that the number of ozone bubbles can be increased, and then the contact area between ozone and the water body can be increased to improve the disinfection effect of ozone.

[0044] Further, it further includes a power assembly for driving the shift lever 5 to switch between the first position and the second position. The power assembly includes a movable ring 6 and a contact rod 7 fixedly connected to the movable ring 6. A cross bar 8 is slidably arranged on the shift lever 5, and a contact block 9 is fixedly connected to the cross bar 8. The contact rod 7 abuts against the contact block 9, and a first spring 10 is arranged between the contact block 9 and the adapter pipe 2. Specifically, the inside of the movable ring 6 is open, and its outer diameter dimension is the same as the inner diameter dimension of the second horizontal section 203 away from the dispersion disc 3, and its inner diameter dimension is smaller than the inner diameter dimension of the second horizontal section 203 away from the dispersion disc 3, that is, the end of the movable ring 6 is located on the ozone delivery stroke. An activity groove 11 adapted to the movable ring 6 is provided in the inner wall of the second horizontal section 203 so that the movable ring 6 can axially move along the second horizontal section 203. Two installation grooves 12 are arranged inside the second horizontal section 203. There are two contact blocks 9, and the two contact blocks 9 are respectively slidably arranged in the two installation grooves 12, and a wedge surface is arranged on the contact block 9. The contact rod 7 is preferably two, one end of the contact rod 7 is fixedly connected to the end face of the movable ring 6, and the other end abuts against the wedge surface of the contact block 9. The cross bar 8 is perpendicularly arranged with the shift lever 5, that is, a mesh structure is formed between the cross bar 8 and the shift lever 5. The cross bar 8 penetrates through the side wall of the installation groove 12 and is fixedly connected to the contact block 9. The first spring 10 should be no less than one, one end of which is fixedly connected to the contact block 9, and the other end is fixedly connected to the side wall of the installation groove 12. The function of such a setting is that when the adapter pipe 2 is not in use, under the elastic force of the first spring 10 and the action of the contact block 9, the shift lever 5 is in the first position. When ozone is introduced into the adapter pipe 2, the ozone will contact the end face of the movable ring 6. When the pressure of the ozone on the movable ring 6 is greater than the elastic force of the first spring 10, it will push the movable ring 6 to slide into the activity groove 11, thereby driving the contact rod 7 to move synchronously. Since the contact rod 7 abuts against the contact block 9, the contact block 9, the cross bar 8 and the shift lever 5 will be driven to move synchronously, so that the shift lever 5 is passively switched from the first position to the third position, and the first spring 10 is charged. When the power of the booster pump increases, its acting force on the movable ring 6 will also increase, so that the contact block 9, the cross bar 8 and the shift lever 5 continue to move, so that the shift lever 5 is passively switched from the third position to the second position, and the first spring 10 is further charged. When the power of the booster pump decreases until it disappears, the elastic force of the first spring 10 is released, so that the shift lever 5 is switched from the second position to the third position and finally to the first position, so as to realize the passive switching of the shift lever 5 between the first position, the second position and the third position.

[0045] It should be noted that when the booster pump is in an abnormal state (or when the boosting multiple of the booster pump is greater than the applicable range of the adapter pipe 2), resulting in excessive power provided by it, ozone will quickly fill the inside of each pipeline, causing excessive pressure inside the pipeline and easily damaging the pipeline. To solve the above problems, as another embodiment of the present invention, a pressure relief hole 13 is provided on the adapter pipe 2, and a baffle 14 is slidably provided inside the adapter pipe 2. The baffle 14 has a first state of blocking the pressure relief hole 13 and a second state of opening the pressure relief hole 13. A second spring 15 is provided between the baffle 14 and the adapter pipe 2; further includes a locking member for fixing the baffle 14 in the first state. Specifically, the pressure relief hole 13 is arranged along the radial direction of the second horizontal section 203. The baffle 14 is an arc-shaped plate, and a through hole through which the abutting rod 7 can pass is provided inside it to avoid interference between the baffle 14 and the abutting rod 7. Moreover, the width of the abutting rod 7 is smaller than the radial dimension of the pressure relief hole 13. A receiving groove 16 is provided on the side wall of the pressure relief hole 13. The baffle 14 is slidably connected to the receiving groove 16, and the cross-sectional dimension of the baffle 14 is larger than the cross-sectional dimension of the pressure relief hole 13. One end of the second spring 15 is fixedly connected to the side wall of the receiving groove 16, and the other end is fixedly connected to the baffle 14, and the second spring 15 is in a stretched state. The first state of the baffle 14 is also that it coincides with the pressure relief hole 13 to block the pressure relief hole 13. The second state of the baffle 14 is also that it is away from the pressure relief hole 13 to open the pressure relief hole 13. The locking member can be an existing structure such as a bolt. That is, when the bolt is inserted into the baffle 14, the position of the baffle 14 is locked. When the bolt is away from the baffle 14, the position of the baffle 14 is unlocked. The function of such a setting is that the pressure inside the adapter pipe 2 can be measured by an existing structure such as a pressure gauge. When the pressure inside the adapter pipe 2 is normal, the baffle 14 is in the first state under the action of the locking member, and at this time the second spring 15 is in a stretched state to block the pressure relief hole 13. When the pressure inside the adapter pipe 2 is too high, the locking member is controlled to be away from the baffle 14. At this time, the baffle 14 is unlocked, and the elastic force of the second spring 15 is released, so that the baffle 14 slides into the receiving groove 16 to switch the baffle 14 from the first state to the second state. After the pressure relief is completed, the baffle 14 is pulled back to switch the baffle 14 from the second state to the first state. At this time, the locking member operates to fix the baffle 14 in the first state again.

[0046] It should be noted that, to prevent water from entering the pressure relief hole 13, a sealing plate 17 can be rotatably arranged at one end of the pressure relief hole 13 away from the central axis of the dispersion plate 3. A first torsion spring (not shown) is provided between the sealing plate 17 and the rotating connecting pipe 2. Under the action of the inner wall of the pressure relief hole 13 blocking the sealing plate 17, the elastic force of the first torsion spring has a tendency to drive the sealing plate 17 to rotate towards the central axis direction of the dispersion plate 3. However, the sealing plate 17 can rotate away from the central axis direction of the dispersion plate 3. The purpose of this setting is that under the action of the elastic force of the first spring, the sealing plate 17 blocks the pressure relief hole 13. When ozone enters the pressure relief hole 13 and the thrust of the ozone on the sealing plate 17 is greater than the elastic force of the first torsion spring, the sealing plate 17 will rotate away from the central axis direction of the dispersion plate 3 and store energy for the first torsion spring to open the pressure relief hole 13 to achieve pressure relief. After the pressure relief is completed, the elastic force of the first torsion spring is released to drive the sealing plate 17 to automatically reset to achieve the function of one-way pressure relief.

[0047] Preferably, the locking member includes a locking rod 18 provided on the abutting block 9. A locking hole 19 adapted to the locking rod 18 is formed on the baffle 14, and the locking rod 18 is inserted into the locking hole 19. Specifically, the locking rod 18 is an L-shaped rod, and the direction of the locking hole 19 is perpendicular to the sliding direction of the baffle 14. One end of the locking rod 18 is fixedly connected to the abutting block 9, and the other end is inserted into the locking hole 19. The purpose of this setting is that under the action of the insertion of the locking rod 18 into the locking hole 19, the position of the baffle 14 can be fixed, so that the baffle 14 cannot slide along the axial direction of the second horizontal section 203. When the power of the booster pump increases abnormally, the acting force of the ozone on the movable ring 6 will increase, causing the movable ring 6 to slide a greater distance towards the movable groove 11, and further causing the abutting block 9 to move a greater distance. When the abutting block 9 moves, it will drive the locking rod 18 to slide away from the locking hole 19. When the locking rod 18 is completely separated from the locking hole 19, the elastic force of the second spring 15 is released, driving the baffle 14 to switch from the first state to the second state to open the pressure relief hole 13 to achieve the function of passive pressure relief. Moreover, this method can open the pressure relief hole 13 without the high-pressure ozone completely filling the pipeline, thus improving safety. After the pressure relief is completed, the locking rod 18 is provided with a force away from the locking hole 19 through the cross bar 8 and the abutting block 9, and the first spring 10 is stored with energy. At this time, the baffle 14 is controlled to move horizontally. When the locking hole 19 coincides with the locking rod 18, the force on the cross bar 8 and the abutting block 9 is cancelled. At this time, the elastic force of the first spring 10 is released to insert the locking rod 18 into the locking hole 19 again, thereby fixing the baffle 14 in the first state.

[0048] When the dispersion disc 3 is in use, impurities will continuously adhere to the inner wall of its through hole 4. Over time, the through hole 4 will be blocked, thereby affecting the passing efficiency of ozone. To solve the above problems, as another embodiment of the present invention, a passive cleaning member for removing impurities inside the through hole 4 is provided on the dispersion disc 3. The passive cleaning member includes a transmission ring 20 rotatably provided on the dispersion disc 3. A scraping plate 21 is provided on the transmission ring 20. The scraping plate 21 is in contact with the inner wall of the through hole 4. A transmission rod 22 is fixedly connected to the transmission ring 20. The transmission rod 22 is located on the movement stroke of the stop rod 5, and an avoidance groove 23 adapted to the transmission rod 22 is provided on the stop rod 5.Specifically, the number and position of the transmission rings 20 are arranged corresponding to the through holes 4, and the transmission rings 20 are rotatably arranged on the side of the dispersion plate 3 away from the pressure relief holes 13. The inner diameter size of the transmission rings 20 is adapted to the inner diameter size of the through holes 4. An annular groove 24 is formed in the through holes 4 on this side. The transmission rings 20 are rotatably connected to the annular groove 24, and a limiting structure for preventing the two from separating is arranged between the transmission rings 20 and the annular groove 24. There are multiple scraping plates 21, and the multiple scraping plates 21 are arranged on the inner circumferential surface of the transmission rings 20. The length of the scraping plates 21 plus the axial length of the transmission rings 20 is equal to the axial length of the through holes 4. The transmission rods 22 are preferably cylindrical rods, which are fixedly connected to the end faces of the transmission rings 20 away from the through holes 4 and are located on the moving stroke of the blocking rods 5. The avoidance grooves 23 are horizontally arranged and are on the same straight line as the left and right ends of the through holes 4. The purpose of such a setting is that since the position of the transmission rings 20 is not fixed, under the action of factors such as the friction between the transmission rings 20 and the annular groove 24, the self-gravity of the transmission rods 22, and the resistance of the water body, the multiple transmission rods 22 can be located at different positions and the positions are not fixed. Therefore, when the blocking rods 5 move horizontally to switch between their respective positions, the following two situations will occur. First, this is the most common situation. The transmission rods 22 are located at positions away from the left and right ends of the through holes 4, that is, at this time, they are located on the moving stroke of the main body of the blocking rods 5. At this time, the blocking rods 5 will abut against the transmission rods 22 to drive the transmission rods 22 and the transmission rings 20 to rotate around the central axis of the through holes 4, thereby driving the scraping plates 21 on their inner walls to rotate synchronously. Since the scraping plates 21 are in contact with the inner walls of the through holes 4, the scraping plates 21 will scrape off the impurities on the inner walls of the through holes 4 to achieve passive cleaning of the through holes 4. Finally, the transmission rods 22 will move to the left and right ends of the through holes 4. At this time, the transmission rods 22 will pass through the avoidance grooves 23 and will not block the blocking rods 5, enabling the baffle plates 14 to switch normally between their respective positions. Second, this is a very rare situation. The transmission rods 22 are located at the left and right ends of the through holes 4, causing the movement of the blocking rods 5 to drive the avoidance grooves 23 to move synchronously, so that the transmission rods 22 pass through the avoidance grooves 23 to avoid interference between the transmission rods 22 and the blocking rods 5. Under the action of various external factors, the transmission rods 22 will not always be in this position. As long as the transmission rods 22 are not in this position, the main body of the blocking rods 5 will abut against them to achieve the effect of passive cleaning.

[0049] As a preferred embodiment of the present invention, in order to fix the movement stroke of the transmission rods 22, that is, to fix the rotation angle of the transmission rings 20, a second torsion spring or other structures can be arranged between the transmission rings 20 and the annular groove 24, so that it has the ability to automatically reset after rotation.

[0050] Only certain exemplary embodiments of the present invention have been described above by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
