Description

Technical Field

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

[0002] It is well known that ozone has a relatively active chemical property and strong oxidizing property, which makes it widely used 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 delivered to the water body through a delivery pump, and relying on the strong oxidizing property of ozone, harmful substances in the water body can be killed.

[0003] For example, the Chinese patent document with the authorization announcement number CN209122956U, the announcement date 2019-07-19, and the name "A Pressurized Ozone Disinfection Cleaning Pool" includes a clean water pipeline for introducing clean water and a gas pipeline for introducing ozone, wherein the clean water pipeline includes a water inlet coil arranged along the rectangular surface of the tank body and a plurality of water outlet pipes vertically connected to the water inlet coil, and a spherical connector is arranged at the joint of the water inlet coil and the water outlet pipe; the gas pipeline includes an air inlet coil, which is arranged above the water inlet coil and parallel to the water inlet coil; it also includes a vertical connecting pipe for connecting the water inlet coil and the air inlet coil, and the spherical connector is also provided with a vent connected to the vertical connecting pipe; it also includes a high-pressure pump, which is connected to the gas pipeline. While injecting ozone, the utility model increases the flow rate and high pressure of the flushing disinfectant water, thereby improving the disinfection effect.

[0004] The shortcomings of the above-mentioned prior art are that multiple outlet pipes are connected to the water inlet pipe to increase the range of action of ozone.

[0020] 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.

[0021] In the description of the present invention, it is to be understood that Fig.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.

[0022] Reference Figure 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.

[0023] 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.

[0024] 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.

[0025] Furthermore, the dispersion disk 3 is provided with a passive adjustment mechanism for adjusting the conduction area of ​​the through hole 4. The passive adjustment mechanism includes a plurality of baffles 5, and the positions of the plurality of baffles 5 are arranged corresponding to the positions of the plurality of through holes 4; the baffles 5 have 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 rows, and the multiple baffle rods 5 are arranged corresponding to the positions of the multiple rows of through holes 4. When the baffle rod 5 is in the first position, the multiple baffle rods 5 respectively have overlapping parts with the multiple rows of through holes 4 to partially block the through holes 4. When the baffle rod 5 is in the second position, the multiple baffle rods 5 are completely separated from the multiple rows of through holes 4 to completely connect the through holes 4. The effect of such a setting is that when the pressure inside the transfer tube 2 is at a normal value, the baffle rod 5 is located between the first position and the second position, that is, the baffle rod 5 does not completely connect the through holes 4, but does not block as much of the through holes 4 as when the baffle rod 5 is in the first position (based on the convenience of description, the baffle rod 5 in this state is called the third position). At this time, ozone can be normally transported to the water body. When the power of the booster pump becomes larger, the baffle rod 5 is moved from the third position (such as Figure 6c ) to the second position (as shown) Figure 6b As shown), at this time, the through hole 4 is completely opened, thereby reducing the pressure of the gas output from the transfer tube 2. When the power of the boost pump becomes smaller, the blocking rod 5 is switched from the third position to the first position. At this time, the blocking rod 5 increases the area blocked by the through hole 4, thereby reducing the conductive area of ​​the through hole 4 to increase the pressure of the gas output from the transfer tube 2, thereby trying to maintain the constant pressure of the gas output from the transfer tube 2.

[0026] 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 of the plurality of rows of through holes 4 (eg Figure 6a As shown), at this time, each through hole 4 is divided into two left and right passing areas, which corresponds to the state when the internal pressure of the transfer tube 2 is relatively small. The advantages of such a setting are, firstly, further reducing the conduction area of ​​the through hole 4 to increase the output pressure of ozone, and secondly, the number of ozone shares is doubled, thereby increasing the number of ozone bubbles, and then increasing the contact area between ozone and water, so as to achieve the improvement of the disinfection effect of ozone.

[0027] Furthermore, it also includes a power assembly for driving the baffle rod 5 to switch between the first position and the second position. The power assembly includes a movable ring 6 and an abutment rod 7 fixed to the movable ring 6, a cross bar 8 is slidably provided on the baffle rod 5, and an abutment block 9 is fixed to the cross bar 8, the abutment rod 7 abuts against the abutment block 9, and a first spring 10 is provided between the abutment block 9 and the transfer tube 2. Specifically, the interior of the movable ring 6 is open, and its outer diameter is the same as the inner diameter of the end of the second horizontal section 203 away from the dispersion disk 3, and its inner diameter is smaller than the inner diameter of the end of the second horizontal section 203 away from the dispersion disk 3, that is, the end of the movable ring 6 is located on the ozone conveying stroke, and a movable 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 move axially along the second horizontal section 203, and two mounting grooves 12 are provided inside the second horizontal section 203, and there are two abutment blocks 9, and the two abutment grooves 12 are provided. The blocks 9 are respectively slidably arranged in the two mounting grooves 12, and a wedge-shaped surface is arranged on the abutting block 9. There are preferably two abutting rods 7, one end of the abutting rod 7 is fixedly connected to the end surface of the movable ring 6, and the other end is abutted with the wedge-shaped surface of the abutting block 9. The cross bar 8 and the blocking rod 5 are arranged vertically, that is, a mesh structure is formed between the cross bar 8 and the blocking rod 5. The cross bar 8 passes through the side wall of the mounting groove 12 and is fixedly connected to the abutting block 9. There should be no less than one first spring 10, one end of which is fixedly connected to the abutting block 9, and the other end is fixedly connected to the side wall of the mounting groove 12. The effect of such a setting is that when the transfer tube 2 is not When in use, under the action of the elastic force of the first spring 10 and the abutment block 9, the blocking rod 5 is in the first position. When ozone is introduced into the transfer tube 2, the ozone will contact the end surface 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, the movable ring 6 will be pushed to slide toward the inside of the movable groove 11, thereby driving the abutment rod 7 to move synchronously. Since the abutment rod 7 abuts against the abutment block 9, the abutment block 9, the cross bar 8 and the blocking rod 5 will be driven to move synchronously, so that the blocking rod 5 is passively switched from the first position to the third position. The first spring 10 is charged, and when the power of the boost pump increases, the force acting on the movable ring 6 will also increase, so that the abutment block 9, the cross bar 8 and the blocking rod 5 continue to move, so that the blocking rod 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 boost pump decreases until it disappears, the elastic force of the first spring 10 is released, so that the blocking rod 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 blocking rod 5 among the first position, the second position and the third position.

[0028] It should be noted that when the boost pump is in an abnormal state (or the pressurization multiple of the boost pump is greater than the applicable range of the transfer tube 2), so that the power it provides is too large, ozone will quickly fill the inside of each pipe, causing the pressure inside the pipe to be too high, which can easily damage the pipe. To solve the above problem, as another embodiment of the present invention, a pressure relief hole 13 is provided on the transfer tube 2, and a baffle 14 is slidably provided inside the transfer tube 2. The baffle 14 has a first state for blocking the pressure relief hole 13 and a second state for opening the pressure relief hole 13. A second spring 15 is provided between the baffle 14 and the transfer tube 2; and a locking member for fixing the baffle 14 in the first state is also included. Specifically, the pressure relief hole 13 is arranged along the radial direction of the second horizontal section 203, and the baffle 14 is an arc-shaped plate, and a through hole is provided inside the baffle 14 for the abutment rod 7 to pass through, so as to avoid interference between the baffle 14 and the abutment rod 7, and the width of the abutment rod 7 is smaller than the radial dimension of the pressure relief hole 13, and a receiving groove 16 is provided on the side wall of the pressure relief hole 13, and 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, and the first state of the baffle 14 is that it coincides with the pressure relief hole 13 to block the pressure relief hole 13, and the second state of the baffle 14 is that it is away from the pressure relief hole 13 to open the pressure relief hole 13, and the locking member can be an existing structure such as a latch, that is, the latch is plugged into the baffle 14 When the latch and the baffle 14 are separated, the position of the baffle 14 is locked, and when the latch and the baffle 14 are separated, the position of the baffle 14 is unlocked. The purpose of such a setting is that the pressure inside the transfer tube 2 can be measured by an existing structure such as a pressure gauge. When the pressure inside the transfer tube 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 transfer tube 2 is too large, the locking member and the baffle 14 are controlled to be separated. 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 accommodating 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 in the opposite direction 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.

[0029] It should be noted that, in order to prevent water from entering the pressure relief hole 13, a blocking plate 17 can be rotatably provided at one end of the pressure relief hole 13 away from the central axis of the dispersion disk 3, and a first torsion spring (not shown) is provided between the blocking plate 17 and the transfer tube 2, and the blocking plate 17 is blocked by the inner wall of the pressure relief hole 13, so that the elastic force of the first torsion spring has a tendency to drive the blocking plate 17 to rotate toward the central axis of the dispersion disk 3, but the blocking plate 17 can rotate in a direction away from the central axis of the dispersion disk 3, so that The purpose of the setting is that under the action of the elastic force of the first torsion 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 in the direction away from the central axis of the dispersion disk 3, and accumulate force in the first torsion spring to open the pressure relief hole 13 and 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, so as to achieve the effect of one-way pressure relief.

[0030] Preferably, the locking member includes a locking rod 18 disposed on the abutment block 9, and a locking hole 19 adapted to the locking rod 18 is provided on the baffle 14, and the locking rod 18 is plugged 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 fixed to the abutment block 9, and the other end is plugged into the locking hole 19. The effect of such a setting is that, under the effect of the plugging of the locking rod 18 and 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 force of ozone on the movable ring 6 will increase, so that the movable ring 6 slides a greater distance toward the movable groove 11, and then the abutment block 9 moves a greater distance. When the abutment block 9 moves, it will drive the locking rod 18 to slide in the direction away from the locking hole 19. When the locking rod 18 is completely disengaged from the locking hole 19, the locking rod 18 will be completely disengaged from the locking hole 19. After the pressure relief is completed, the elastic force of the second spring 15 is released, thereby driving the baffle 14 to switch from the first state to the second state, so as to open the pressure relief hole 13 and realize the passive pressure relief. In this way, the pressure relief hole 13 can be opened without the need for high-pressure ozone to completely fill the pipeline, thereby improving safety. When the pressure relief is completed, the cross bar 8 and the abutment block 9 provide a force for the locking rod 18 to move away from the locking hole 19, and the first spring 10 is charged. 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 abutment block 9 is canceled. 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.

[0031] When the dispersion disc 3 is in use, impurities will continue to adhere to the inner wall of the through hole 4. If this continues for a long time, the through hole 4 will be blocked, thereby affecting the passing efficiency of ozone. To solve the above problem, as another embodiment of the present invention, the dispersion disc 3 is provided with a passive cleaning member for removing impurities inside the through hole 4. The passive cleaning member includes a transmission ring 20 rotatably arranged on the dispersion disc 3, the transmission ring 20 is provided with a scraper 21, the scraper 21 is in contact with the inner wall of the through hole 4, the transmission ring 20 is fixed with a transmission rod 22, the transmission rod 22 is located on the movement stroke of the baffle rod 5, and the baffle rod 5 is provided with an avoidance groove 23 adapted to the transmission rod 22.Specifically, the number and position of the transmission ring 20 are arranged corresponding to the through hole 4, and the transmission ring 20 is rotatably arranged on the side of the dispersion disk 3 away from the pressure relief hole 13. The inner diameter of the transmission ring 20 is adapted to the inner diameter of the through hole 4. The through hole 4 is provided with an annular groove 24 on this side. The transmission ring 20 is rotatably connected to the annular groove 24, and a limiting structure for preventing the two from being separated is provided between the transmission ring 20 and the annular groove 24. There are multiple scrapers 21, and multiple scrapers 21 are provided on the inner circumferential surface of the transmission ring 20. The length of the scraper 21 plus the axial length of the transmission ring 20 is equal to the axial length of the through hole 4. The movable rod 22 is preferably a cylindrical rod, which is fixed to the end face of the transmission ring 20 away from the through hole 4 and is located on the movement stroke of the blocking rod 5. The avoidance groove 23 is arranged horizontally and is in the same straight line as the left and right ends of the through hole 4. The effect of such a setting is that, since the position of the transmission ring 20 is not fixed, under the influence of factors such as the friction between the transmission ring 20 and the annular groove 24, the gravity of the transmission rod 22 itself, and the resistance of the water body, multiple transmission rods 22 can be located at different positions, and the positions are not fixed. Therefore, in the process of the blocking rod 5 moving horizontally to realize its own switching between various positions, the following will occur: There are two situations. First, this situation is the majority of situations. The transmission rod 22 is located at a position far away from the left and right ends of the through hole 4, that is, at this time it is located on the movement stroke of the blocking rod 5 body. At this time, the blocking rod 5 will abut against the transmission rod 22 to drive the transmission rod 22 and the transmission ring 20 to rotate around the central axis of the through hole 4, thereby driving the scraper 21 on the inner wall thereof to rotate synchronously. Since the scraper 21 fits the inner wall of the through hole 4, the scraper 21 will scrape off the impurities on the inner wall of the through hole 4 to achieve passive cleaning of the through hole 4. The transmission rod 22 will eventually move to the positions of the left and right ends of the through hole 4. At this time, the transmission rod 22 will pass through the avoidance groove 23 and will not block the baffle rod 5, so that the baffle plate 14 can switch normally between various positions. Secondly, this situation is a very rare case. The transmission rod 22 is located at the left and right ends of the through hole 4, so that the movement of the baffle rod 5 will drive the avoidance groove 23 to move synchronously, so that the transmission rod 22 passes through the avoidance groove 23 to avoid interference between the transmission rod 22 and the baffle rod 5. Under the influence of various external factors, the transmission rod 22 will not always be in this position. As long as the transmission rod 22 is not in this position, the baffle rod 5 body will abut against it to achieve a passive cleaning effect.

[0032] As a preferred embodiment of the present invention, in order to make the movement stroke of the transmission rod 22 fixed, that is, the rotation angle of the transmission ring 20 fixed, a second torsion spring or other structure can be set between the transmission ring 20 and the annular groove 24, which has the ability to automatically reset after rotation.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
