Description

Technical Field

[0001] This invention belongs to the technical field of air flotation water purification devices, and particularly relates to an air flotation water purification device and its usage method. Background Technology

[0002] The bubble releaser is one of the core components of the air flotation water purification device. Its main function is to convert compressed air into a large number of tiny, evenly distributed microbubbles, so that the bubbles can fully collide with and adsorb impurities such as suspended solids and oils in the water, forming scum with a density less than water that floats to the surface.

[0003] Existing bubble releasers often experience clogging during long-term operation. When clogging occurs, the releaser must be disassembled and cleaned, which is not only cumbersome but also costly to maintain. In addition, the release gap of most existing bubble releasers is a fixed structure, which cannot adjust the diameter and release density of bubbles in real time according to changes in influent water quality and suspended solids concentration. This limits their applicability and makes them difficult to adapt to complex and ever-changing water treatment conditions. To solve the above problems, there is an urgent need for a bubble releaser for flotation water purification devices and its usage method. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of difficult maintenance and inability to dynamically adjust bubble parameters in existing bubble releasers, and to propose a bubble releaser for air flotation water purification devices and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bubble release device for an air flotation water purification system, comprising a main shell, air pipes, and a base assembly. Multiple air pipes are installed at equal intervals on the outer wall of the main shell, and the multiple air pipes communicate with the inner cavity of the main shell. The base assembly includes a base body and an annular box. Bolts are used to fix the base body to the main shell. A sealing gasket is provided on the contact surface between the main shell and the base body. The annular box is fixedly installed at the center of the bottom surface of the inner cavity of the base body. The device also includes: The air distribution assembly includes an air distribution plate and a locking block. The locking block is fixedly installed on the bottom surface of the air distribution plate, and the central axis of the air distribution plate and the locking block are on the same straight line. The connecting assembly includes a fixed pile, a support rod, and a support plate. The fixed pile is fixedly connected to the outer wall of the locking block. The support rod movably passes through the top of the annular box. The support plate is fixedly installed on the top of the support rod. The support rod drives the fixed pile to move synchronously. An adjustment assembly is located inside the annular box. The adjustment assembly includes a lifting plate, a lead screw, and a guide rod. One end of the support rod inside the annular box is fixedly connected to the lifting plate. The lead screw is threaded and passes through the lifting plate. The guide rod is fixedly installed inside the annular box and moves through the lifting plate. The cleaning component includes multiple flip plates that are fitted into the center of the top of the air distribution plate.

[0006] As a further description of the above technical solution: The base assembly further includes: a mounting groove, which is located at the center of the annular box; a venting pipe, which is fixedly inserted through the central shaft hole of the mounting groove; and a sealing ring, which is fixedly installed on the outer wall of the venting pipe.

[0007] As a further description of the above technical solution: The base assembly further includes a drain plug, which engages with a drain port on the bottom surface of the base body, and the bottom end of the drain pipe is connected to the drain port on the bottom surface of the base body.

[0008] As a further description of the above technical solution: The gas distribution assembly further includes: a gas channel, which is opened through the gas distribution plate and the locking block, and the gas pipe is movably locked in the gas channel, with a sealing ring located between the gas pipe and the locking block.

[0009] As a further description of the above technical solution: The connecting component further includes a protrusion, which is fixedly installed at the bottom end of the fixed pile.

[0010] As a further description of the above technical solution: The connecting component further includes a groove, which is formed on the top of the tray, and the protrusion engages with the corresponding groove.

[0011] As a further description of the above technical solution: The adjustment assembly further includes: an adjustment knob, which is embedded in the bottom of the base body and a sealing ring is provided between the adjustment knob and the base body. The top of the adjustment knob is fixedly connected to one end of a lead screw, and the lead screw is rotatably installed in the inner cavity of the annular box.

[0012] As a further description of the above technical solution: The cleaning component further includes: a mounting base, which is fixedly installed on the inner wall of the unblocking air groove hole at the central axis of the air distribution plate; A flipping arm, one end of which is fixedly installed at the bottom end of the flipping plate, and the other end of which is movably engaged in the inner cavity of the mounting base; A pin is fixedly inserted through the tilting arm, and both ends of the pin are movably installed in the inner cavity of the mounting base.

[0013] A method for using an air flotation water purification device with an air bubble release device includes the following steps: Step 1: Connect the dissolved air water pipeline to the main shell. The dissolved air water is distributed to multiple air pipes through the inner cavity of the main shell. Microbubbles are released from the end of the air pipes for air flotation water purification. Step 2: According to the water quality and treatment requirements, rotate the adjustment knob to make the screw rotate forward or backward. The lifting plate drives the support rod and the air distribution plate to rise or fall, increasing or decreasing the release gap between the air distribution plate and the base body, thereby adjusting the diameter and release density of the bubbles in real time during operation. Step 3: When the bubble release decreases or the pressure increases, stop the water intake or reduce the pressure. Then, introduce compressed air or high-pressure water into the air venting groove through the air venting pipe. The compressed air or high-pressure water impacts the tilting plate through the air venting groove, causing the tilting plate to rotate around the pin shaft. At the same time, the airflow or water flow flows backward from the top of the air distribution plate to flush out the impurities attached to the air distribution plate and restore the release performance.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, depending on the different influent water quality, suspended solids concentration and treatment requirements, the adjustment knob at the bottom of the base body can be rotated to drive the lead screw to rotate, causing the lifting plate to rise and fall along the guide rod and move the air distribution plate up and down through the support rod and the support plate. The release gap between the air distribution plate and the base body can be adjusted in real time, thereby precisely controlling the diameter and release density of the bubbles, so that the collision and adsorption efficiency of the bubbles and suspended solids reaches the optimal state, greatly improving the treatment effect and application range of the air flotation water purification device.

[0015] 2. In this invention, when a decrease in bubble release or an increase in system pressure is observed, there is no need to stop the machine and disassemble the device. Simply pull out the unblocking plug and introduce compressed air or high-pressure water into the unblocking air groove through the unblocking air pipe. This will push the flipping plate to flip upwards, and use the high-pressure medium to flush the impurities from the air pipe inlet and the surface of the air distributor plate from the top of the air distributor plate. This achieves thorough cleaning, quickly restores the release performance of the device, significantly shortens maintenance time, reduces operating costs, and ensures the continuous and stable operation of the air flotation system.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 8 The present invention provides a technical solution: an air flotation water purification device with an air bubble release device, including a main shell 1, an air pipe 2 and a base assembly 3. There are multiple air pipes 2, which are installed at equal intervals on the outer wall of the main shell 1 and the multiple air pipes 2 communicate with the inner cavity of the main shell 1. The base assembly 3 includes a base body 301 and an annular box 302. The base body 301 is fixedly connected to the main shell 1 by bolts 4. A sealing gasket 5 is provided on the contact surface between the main shell 1 and the base body 301. The annular box 302 is fixedly installed at the center of the bottom surface of the inner cavity of the base body 301.

[0027] Specifically, by setting multiple air pipes 2 at equal intervals on the outer wall of the main housing 1 and communicating with the inner cavity, multi-point synchronous exhaust can be achieved, ensuring uniform air pressure distribution in the inner cavity of the main housing 1 and avoiding uneven bubble release and inconsistent bubble size caused by excessively high or low local air pressure. Bolts 4 are used to fix the base body 301 to the main housing 1, which has high connection strength and is easy to disassemble and assemble, facilitating the maintenance and replacement of internal components of the device in the future. A sealing gasket 5 is set on the contact surface between the two, which can effectively improve the airtightness between the main housing 1 and the base body 301, preventing energy loss and reduced bubble generation quality caused by gas leakage. The annular box 302 is fixed to the center of the bottom surface of the inner cavity of the base body 301, providing an independent and stable installation space for the subsequent adjustment component 8 and connection component 7.

[0028] like Figure 2 and Figure 4 As shown, the base assembly 3 also includes: a mounting groove 303, a venting pipe 304, and a sealing ring 305. The mounting groove 303 is located at the center of the annular box 302; the venting pipe 304 is fixedly inserted into the central shaft hole of the mounting groove 303; and the sealing ring 305 is fixedly installed on the outer wall of the venting pipe 304.

[0029] Specifically, an installation groove 303 is provided in the center of the annular box 302, which can accurately position the unblocking air pipe 304, ensuring that the unblocking air pipe 304 coincides with the central axis of the entire device, and avoiding the obstruction of the air distribution plate 601 due to eccentricity. As an independent unblocking channel, the unblocking air pipe 304 can achieve online unblocking without disassembling the device, solving the pain point that traditional release devices must be stopped and disassembled for cleaning after blockage. A sealing ring 305 is provided on the outer wall of the unblocking air pipe 304, which can effectively seal the gap between the unblocking air pipe 304 and the locking block 602, preventing gas in the main housing 1 from leaking out of the gap, ensuring that all gas can enter the release gap to form effective bubbles, and improving gas utilization.

[0030] like Figure 6 As shown, the base assembly 3 also includes a drain plug 306, which engages with the drain interface on the bottom surface of the base body 301, and the bottom end of the drain pipe 304 is connected to the drain interface on the bottom surface of the base body 301.

[0031] Specifically, by engaging the unblocking plug 306 within the unblocking interface on the bottom surface of the base body 301, an effective seal is formed at the bottom of the unblocking air pipe 304 during normal operation, preventing sewage and impurities in the flotation tank from entering the unblocking air pipe 304 and causing blockage, thus ensuring that the unblocking channel remains unobstructed for a long time. When unblocking operations are required, simply pull out the unblocking plug 306 to quickly connect to the compressed air or high-pressure water pipeline. The operation is simple and convenient, requiring no disassembly of the main body of the device, which greatly shortens the unblocking operation time and reduces the difficulty of maintenance.

[0032] like Figure 3 As shown, the air distribution assembly 6 includes an air distribution plate 601 and a locking block 602. The locking block 602 is fixedly installed on the bottom surface of the air distribution plate 601, and the central axis of the air distribution plate 601 and the locking block 602 are on the same straight line.

[0033] Specifically, the gas distribution plate 601, as the core component for bubble release, can evenly disperse the gas in the main housing 1 to the entire release gap, forming fine and uniform bubbles; the locking block 602 is coaxially set with the gas distribution plate 601, which can ensure that the gas distribution plate 601 always remains horizontal during the lifting and lowering process, avoiding uneven release gaps caused by tilting, and thus preventing the problem of local bubbles being too large or too small; the locking block 602 and the unblocking air pipe 304 cooperate to form a guide structure, further improving the stability and accuracy of the lifting and lowering of the gas distribution plate 601.

[0034] like Figure 3 As shown, the air distribution assembly 6 also includes: an air channel 603, which is opened through the air distribution plate 601 and the locking block 602. The air channel 304 is movably locked in the air channel 603, and the sealing ring 305 is located between the air channel 304 and the locking block 602.

[0035] Specifically, the air duct 603 serves both guiding and unblocking functions. It acts as a guide channel for the lifting and lowering of the air distribution plate 601, ensuring its smooth vertical movement, and also as a channel for delivering the unblocking medium, directly supplying compressed air or high-pressure water to the top of the air distribution plate 601 for reverse flushing. The movable engagement between the air duct 304 and the air duct 603 ensures guiding accuracy without creating additional resistance to the lifting and lowering of the air distribution plate 601. The sealing ring 305, located between the air duct 304 and the engaging block 602, maintains a good sealing effect throughout the entire lifting and lowering stroke of the air distribution plate 601, ensuring that gas does not leak from the gap between them.

[0036] like Figure 3 and Figure 4 As shown, the connecting component 7 includes a fixed pile 701, a support rod 703, and a support plate 704. The fixed pile 701 is fixedly connected to the outer wall of the locking block 602. The support rod 703 movably passes through the top of the annular box 302. The support plate 704 is fixedly installed on the top of the support rod 703. The support rod 703 drives the fixed pile 701 to move synchronously.

[0037] Specifically, the design of the support rod 703 moving through the top of the annular box 302 not only ensures the vertical lifting and lowering of the support rod 703, but also provides support and guidance for the support rod 703.

[0038] like Figure 3 As shown, the connecting component 7 also includes a protrusion 702, which is fixedly installed at the bottom end of the fixing pile 701.

[0039] Specifically, a protrusion 702 is provided at the bottom of the fixed pile 701, which can increase the contact area between the fixed pile 701 and the support plate 704 and improve the stability of power transmission; at the same time, the protrusion 702 can play a positioning role. When installing the air distribution plate 601, it is only necessary to align the protrusion 702 with the corresponding position on the support plate 704 to complete the precise positioning and avoid the air distribution plate 601 being installed off-center.

[0040] like Figure 4 As shown, the connecting component 7 also includes a groove 705, which is formed on the top of the support plate 704, and the protrusion 702 is movably engaged with the corresponding groove 705.

[0041] Specifically, the connection method of movable engagement between protrusion 702 and groove 705 ensures the reliability of power transmission and prevents slippage or misalignment, while also allowing for a small angular adjustment of the air distribution plate 601. This effectively compensates for machining and installation errors and avoids jamming problems caused by insufficient machining precision. This engagement structure achieves a stable connection without any fasteners, further simplifying the disassembly and assembly process of the air distribution plate 601.

[0042] like Figure 5 As shown, the adjustment component 8 is located in the inner cavity of the annular box 302. The adjustment component 8 includes a lifting plate 801, a lead screw 802, and a guide rod 803. One end of the support rod 703 in the cavity of the annular box 302 is fixedly connected to the lifting plate 801. The lead screw 802 is threadedly connected to and passes through the lifting plate 801. The guide rod 803 is fixedly installed in the inner cavity of the annular box 302 and moves through the lifting plate 801.

[0043] Specifically, the transmission structure using a lead screw 802 features high transmission accuracy and good self-locking performance, which can precisely control the lifting distance of the air distribution plate 601, thereby achieving precise adjustment of the release gap and ensuring the adjustment accuracy of bubble diameter and release density. The guide rod 803 prevents the lifting plate 801 from rotating with the lead screw 802, ensuring that the lifting plate 801 moves smoothly only in the vertical direction, thus ensuring the smooth lifting of the support rod 703 and keeping the air distribution plate 601 in a horizontal state at all times. As an intermediate component for power transmission, the lifting plate 801 can convert the rotational motion of the lead screw 802 into the linear motion of the support rod 703, with a simple and reliable structure and high transmission efficiency.

[0044] like Figure 6 As shown, the adjustment assembly 8 also includes an adjustment knob 804, which is embedded in the bottom of the base body 301, and a sealing ring is provided between the adjustment knob 804 and the base body 301. The top of the adjustment knob 804 is fixedly connected to one end of the lead screw 802, and the lead screw 802 is rotatably installed in the inner cavity of the annular box 302.

[0045] Specifically, the adjustment knob 804 is embedded in the bottom of the base body 301, allowing operators to make adjustments directly from outside the device without opening the main housing 1 or entering the device, making operation safe and convenient. A sealing ring is provided between the adjustment knob 804 and the base body 301 to effectively prevent water from the flotation tank from entering the inner cavity of the annular box 302, extending the service life of the transmission mechanism. The adjustment knob 804 is directly fixedly connected to the lead screw 802, resulting in high transmission efficiency and no intermediate transmission links, enabling precise control of the rotation angle of the lead screw 802, thereby achieving fine adjustment of the bubble parameters.

[0046] like Figure 7 As shown, the cleaning component 9 includes multiple flip plates 901, which are fitted into the center of the top of the air distribution plate 601.

[0047] Specifically, multiple flip plates 901 are fitted and installed at the top center of the air distribution plate 601. During normal operation, the flip plates 901 remain flush with the top surface of the air distribution plate 601, which will not interfere with the normal bubble release path and ensure the uniformity and stability of bubble release. When dredging is carried out, the high-pressure medium can push the flip plates 901 upward to form multiple reverse flushing channels, allowing the high-pressure airflow or water flow to spread in all directions and directly impact the impurities at the top surface of the air distribution plate 601 and the inlet of each air pipe 2, achieving thorough cleaning without dead angles. This effectively solves the technical problem that it is difficult to clean the impurities in the dead angles inside the traditional release device and that it is easy to repeatedly clog.

[0048] like Figure 8 As shown, the cleaning component 9 also includes: a mounting base 902, a tilting arm 903, and a pin 904. The mounting base 902 is fixedly installed on the inner wall of the unblocking air groove 603 hole at the central axis of the air distribution plate 601; one end of the tilting arm 903 is fixedly installed on the bottom end of the tilting plate 901, and the other end of the tilting arm 903 is movably engaged in the inner cavity of the mounting base 902; the pin 904 is fixedly inserted through the tilting arm 903, and both ends of the pin 904 are movably installed in the inner cavity of the mounting base 902.

[0049] Specifically, the hinged flip structure using pin 904 allows the flip plate 901 to flip only upwards in one direction. It automatically opens during reverse flushing and automatically closes after unblocking due to its own weight and the gas pressure during normal operation. No additional reset mechanism is required, making the structure simple, reliable, and with a low failure rate. The mounting base 902 is fixed to the inner wall of the unblocking air channel 603, without occupying the effective release area of ​​the air distribution plate 601, and will not affect the normal bubble generation. The movable engagement connection between the flip arm 903 and the mounting base 902 facilitates the individual replacement of the flip plate 901 assembly, reducing maintenance costs.

[0050] Working principle: Dissolved air water enters the inner cavity of the main shell 1, and after distribution, it is released into microbubbles through multiple air pipes 2. Depending on the water quality and treatment requirements, rotating the adjustment knob 804 at the bottom of the base body 301 drives the lead screw 802 to rotate forward or reverse, causing the lifting plate 801 to rise and fall vertically along the guide rod 803. The lifting plate 801 drives the support rod 703 and the top support plate 704 to move synchronously. The support plate 704, through the engagement of the groove 705 and the protrusion 702, drives the fixing pile 701, the engaging block 602, and the air distribution plate 601 to rise or fall, increasing or decreasing the release gap between the air distribution plate 601 and the base body 301, thereby adjusting the diameter and release density of the bubbles in real time during operation. When bubble release is observed... When the flow rate decreases or the pressure increases, stop the water intake or reduce the pressure. Pull out the unblocking plug 306 on the bottom of the base body 301, and introduce compressed air or high-pressure water into the unblocking air groove 603 through the unblocking air pipe 304. The high-pressure medium impacts the flip plate 901 at the top of the air distribution plate 601, causing the flip plate 901 to flip upwards around the pin 904 on the mounting base 902 via the flipping arm 903. At the same time, the airflow or water flow flows backward from the top of the air distribution plate 601 to flush the inlet of the air pipe 2 and the surface of the air distribution plate 601, flushing out the attached impurities. After the unblocking is completed, stop the introduction of high-pressure medium. The flip plate 901 will automatically close by its own weight and the gas pressure during normal operation. Reinstall the unblocking plug 306 to restore the normal operation of the device.

[0051] A method for using a bubble release device in an air flotation water purification system: Step 1: Connect the dissolved air water pipeline to the main shell 1. The dissolved air water is distributed to multiple air pipes 2 through the inner cavity of the main shell 1. Microbubbles are released from the end of the air pipes 2 to perform air flotation water purification.

[0052] Step 2: According to the water quality and treatment requirements, rotate the adjustment knob 804 to make the lead screw 802 rotate forward or backward. The lifting plate 801 drives the support rod 703 and the air distribution plate 601 to rise or fall, increasing or decreasing the release gap between the air distribution plate 601 and the base body 301, thereby adjusting the diameter and release density of the bubbles in real time during operation.

[0053] Step 3: When the amount of bubble release decreases or the pressure increases, stop the water intake or reduce the pressure. Then, introduce compressed air or high-pressure water into the air duct 603 through the air duct 304. The compressed air or high-pressure water impacts the flip plate 901 through the air duct 603, causing the flip plate 901 to flip around the pin 904. At the same time, the airflow or water flow washes the air duct 2 in the opposite direction from the top of the air distribution plate 601, flushing out the impurities attached to the air distribution plate 601 and restoring the release performance.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

The bubble release device for an air flotation water purification system according to claim 1, characterized in that, The adjustment component (8) further includes: An adjustment knob (804) is embedded in the bottom of the base body (301), and a sealing ring is provided between the adjustment knob (804) and the base body (301). The top of the adjustment knob (804) is fixedly connected to one end of the lead screw (802), and the lead screw (802) is rotatably installed in the inner cavity of the annular box (302).

8. The bubble release device for an air flotation water purification apparatus according to claim 4, characterized in that, The cleaning component (9) also includes: Mounting base (902), which is fixedly installed on the inner wall of the unblocking air groove (603) hole at the central axis of the air distribution plate (601); A flip arm (903) is provided, one end of which is fixedly installed at the bottom end of the flip plate (901), and the other end of which is movably engaged in the inner cavity of the mounting base (902). Pin (904) is fixedly inserted through the flip arm (903), and both ends of the pin (904) are movably installed in the inner cavity of the mounting base (902).

9. A method for using the bubble release device of the air flotation water purification apparatus according to any one of claims 1 to 8, characterized in that, Includes the following steps: Step 1: Connect the dissolved air water pipeline to the main shell (1). Dissolved air water is distributed to multiple air pipes (2) through the inner cavity of the main shell (1). Microbubbles are released from the end of the air pipes (2) to perform air flotation water purification. Step 2: According to the water quality and treatment requirements, rotate the adjustment knob (804) to make the lead screw (802) rotate forward or reverse. The lifting plate (801) drives the support rod (703) and the air distribution plate (601) to rise or fall, increasing or decreasing the release gap between the air distribution plate (601) and the base body (301), thereby adjusting the diameter and release density of the bubbles in real time during operation. Step 3: When the amount of bubble release decreases or the pressure increases, stop the water intake or reduce the pressure. Then, through the air duct (304), introduce compressed air or high-pressure water into the air duct (603). The compressed air or high-pressure water impacts the flip plate (901) through the air duct (603), causing the flip plate (901) to flip around the pin (904). At the same time, the airflow or water flow washes the air duct (2) in the opposite direction from the top of the air distribution plate (601), flushing out the impurities attached to the air distribution plate (601) and restoring the release performance.
