Description

Technical Field

[0001] This application relates to the field of water treatment technology, and more specifically, to a water treatment ozone purification device. Background Technology

[0002] Ozone (O3) purification is a highly efficient and pollution-free advanced oxidation technology used in water treatment, and is widely applied in deep treatment, disinfection and decolorization, and removal of recalcitrant organic matter. Ozone is generated by an ozone generator, then mixed with wastewater using an ejector before being fed into the reaction tank.

[0003] In related technologies, when ozone purification devices for water treatment are used for mixed flow, the wastewater flowing through the throat of the ejector is subjected to high concentrations and high activity of ozone, which accelerates the oxidation of deposits and causes scaling. As the scale in the ejector throat increases, the throat gradually narrows, and the reduced inner diameter of the throat leads to a corresponding decrease in the efficiency of the ejector, thus reducing ozone utilization. To address scaling in the ejector throat, regular manual cleaning is usually required. This involves disassembling the ejector, opening the corresponding throat components, and cleaning with an acidic solution; alternatively, acidic solution can be periodically injected from the wastewater outlet to dissolve and clean. Manual cleaning is time-consuming and labor-intensive, and simple acidic solution dissolution is also time-consuming. Therefore, reducing the frequency of manual cleaning and shortening the acidic solution dissolution time are technical problems that need to be solved. Summary of the Invention

[0010] According to some embodiments of this application, the stepping axial flow impeller mechanism further includes a rotating support structure and a compression spring structure. The rotating support structures are respectively disposed in the jet ejector mechanism and the dual-purpose top tube. The axial flow impeller structure slides through multiple rotating support structures and can slide along multiple rotating support structures. The compression spring structure is disposed at the tail end of the axial flow impeller structure. The inner and outer rings of the compression spring structure can rotate relative to each other. The outer ring of the compression spring structure rotates with the axial flow impeller structure. The return spring presses against the inner ring of the compression spring structure.

[0011] According to some embodiments of this application, the rotating support structure includes a rotating support sleeve, a fixed support rod, and a tightening screw. One fixed support rod and two tightening screws are evenly arranged around the periphery of the rotating support sleeve. The fixed support rods on the plurality of rotating support structures are respectively fixedly connected to the lower side of the ejector mechanism and the inner wall of the dual-purpose top tube. The tightening screws on the plurality of rotating support structures pass through the ejector mechanism and the dual-purpose top tube through threaded seals. The fixed support rod supports the rotating support sleeve, and the tightening screws press the rotating support sleeve against the fixed support rod. The axial flow impeller structure slides through the rotating support sleeve.

[0012] According to some embodiments of this application, the compression spring structure includes an outer sleeve, a bearing, an inner sleeve, and a tightening nut. The outer sleeve is threaded onto the tail end of the axial flow impeller structure. The tightening nut tightens the outer sleeve onto the tail end of the axial flow impeller structure. The outer ring of the bearing is fixedly inserted into the outer sleeve. The inner sleeve is fixedly inserted into the inner ring of the bearing. The inner sleeve is fitted onto the axial flow impeller structure. The rear end of the return spring presses against the rotating support structure at the rear end, and the front end of the return spring presses against the side wall of the inner sleeve.

[0013] According to some embodiments of this application, an extension rod is fixedly connected to the outer wall of the outer sleeve, and a magnet is provided at the top end of the extension rod.

[0014] According to some embodiments of this application, the axial flow impeller structure includes an impeller shaft and an axial flow impeller, the axial flow impeller is fixedly sleeved on the impeller shaft, and the axial flow impeller is located between the liquid inlet pipe and the sewage outlet pipe.

[0015] According to some embodiments of this application, the three-way blade holder includes a base, a mounting cylinder, an outer wall scraper, a flared scraper, and a throat scraper. The mounting cylinder is fixedly sleeved on the front end of the axial flow impeller structure. The base is fixedly connected to both sides of the rear end of the mounting cylinder. The outer wall scraper is fixedly connected to the front side of the outer end of the base. The blades of the two outer wall scrapers form an outward-flaring V-shape from back to front. The front end of the flared scraper is fixedly connected to the outer wall of the front end of the mounting cylinder. The rear end of the flared scraper is fixedly connected to the base. The blades of the two flared scrapers form an inward-retracting V-shape from back to front. The throat scraper is disposed on the side wall of the base. The blade surface of the outer wall scraper forms a ° angle with the outer wall of the throat of the jet ejector mechanism. The outer wall scraper gradually approaches the outer wall of the throat of the jet ejector mechanism from back to front. The flared scraper gradually extends into the interior of the throat of the jet ejector mechanism from back to front. The throat scraper gradually approaches the end of the throat of the jet ejector mechanism.

[0016] The beneficial effects of this application are as follows: When cleaning the scale in the throat of the jet ejector, the valves of the sewage inlet pipe, the sewage outlet pipe, and the ozone inlet of the jet ejector mechanism are closed. The dissolving liquid is injected through the inlet pipe and flows out through the first outlet pipe. The dissolving liquid flows in the dual-purpose top pipe. The flow of the dissolving liquid drives the axial flow impeller structure to rotate. The three-blade holder rotates with the axial flow impeller structure. The rotating three-blade holder scrapes away the scale in the throat of the jet ejector mechanism. At the same time, the axial flow impeller structure is subjected to axial thrust in the direction of water flow due to the flow of the dissolving liquid. The axial flow impeller structure moves forward along the axial direction. The three-blade holder moves with the axial flow impeller structure, realizing the cutting action of the three-blade holder. The return spring at the tail end of the axial flow impeller structure is compressed, and the elastic force of the return spring is flat. The axial thrust of the water flow on the axial impeller structure increases with the flow velocity of the dissolving liquid, and the axial thrust on the axial impeller structure in the direction of water flow also increases. The three-blade holder at the front end of the axial impeller structure gradually approaches the throat of the ejector mechanism. Through the rotation of the axial impeller structure, the scale in the throat of the ejector is scraped off layer by layer. Combined with the dissolution of the dissolving liquid, the scale in the throat of the ejector mechanism is reduced as much as possible. This reduces the impact of the scale in the throat of the ejector mechanism on its operation. Firstly, it can extend the time interval and frequency of manual cleaning. Secondly, since some of the scale in the throat is scraped off by the three-blade holder, the amount of scale is reduced. As the three-blade holder scrapes off the scale, the dissolving liquid comes into full contact with the scale, improving the dissolution efficiency and shortening the time required for the dissolving liquid to dissolve.

Detailed Implementation

[0030] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The following description, with reference to the accompanying drawings, describes a water treatment ozone purification device according to an embodiment of this application.

[0033] Please see Figures 1 to 10 The water treatment ozone purification device according to the embodiments of this application includes: a sewage inflow pipe 100, an ejector mechanism 200, a dual-purpose top pipe 300, and a stepping axial flow impeller mechanism 400.

[0034] Please see Figures 1 to 10The sewage inlet pipe 100 is fixedly connected to the flange inlet of the ejector mechanism 200. A first drain pipe 210 is fixedly connected to both the lower side of the ejector mechanism 200 and the lower side of the sewage inlet pipe 100. A dual-purpose top pipe 300 is fixedly connected to the flange outlet of the ejector mechanism 200. The tail end of the dual-purpose top pipe 300 is closed. An inlet pipe 310 and a sewage outlet pipe 320 are respectively installed at the front end of the upper side and the rear end of the lower side of the dual-purpose top pipe 300. Valves are installed at the inlet of the sewage inlet pipe 100, the outlet of the sewage outlet pipe 320, and the ozone inlet of the ejector mechanism 200. The flow rate of the dissolved liquid flowing into the inlet pipe 310 gradually increases. A stepping axial flow impeller mechanism 4... The 00 includes an axial impeller structure 410, a three-way cutter holder 420, and a return spring 430. The axial impeller structure 410 is rotatably disposed inside the rear section of the ejector mechanism 200 and the dual-purpose top tube 300. As the flow rate of the dissolving liquid increases, the axial impeller structure 410 can slide forward along the axial direction of the ejector mechanism 200 and the dual-purpose top tube 300. The three-way cutter holder 420 is fixed to the front end of the axial impeller structure 410 and can gradually approach the throat of the ejector mechanism 200. The return spring 430 is disposed at the rear end of the axial impeller structure 410, and the elastic force of the rear end of the return spring 430 presses the tail end of the axial impeller structure 410.

[0035] When cleaning the scale in the throat of the jet ejector, the valves at the inlet of the sewage inlet pipe 100, the outlet of the sewage outlet pipe 320, and the ozone inlet of the jet ejector mechanism 200 are closed. The dissolving liquid is injected through the inlet pipe 310 and flows out through the first outlet pipe 210. The dissolving liquid flows within the dual-purpose top pipe 300. The flow of the dissolving liquid drives the axial flow impeller structure 410 to rotate. The three-way cutter holder 420 rotates with the axial flow impeller structure 410. The rotating three-way cutter holder 420 scrapes away the scale in the throat of the jet ejector mechanism 200. At the same time, the axial flow impeller structure 410 is subjected to axial thrust in the direction of water flow due to the flow of the dissolving liquid. The axial flow impeller structure 410 moves forward along the axial direction. The three-way cutter holder 420 moves with the axial flow impeller structure 410, realizing the cutting action of the three-way cutter holder 420. The return spring 430 at the tail end of the axial flow impeller structure 410 is compressed and returns to its original position. The elastic force of spring 430 balances the axial thrust of the water flow on the axial impeller structure 410. As the flow rate of the dissolving liquid increases, the axial thrust on the axial impeller structure 410 in the direction of water flow also increases. The three-blade holder 420 at the front end of the axial impeller structure 410 gradually approaches the throat of the ejector mechanism 200. Through the rotation of the axial impeller structure 410, the scale in the throat of the ejector is scraped off layer by layer. In conjunction with the dissolution of the dissolving liquid, the scale in the throat of the ejector mechanism 200 is reduced as much as possible. This reduces the impact of the scale in the throat of the ejector mechanism 200 on the operation of the ejector mechanism 200. Firstly, it can extend the time interval and frequency of manual cleaning. Secondly, since some of the scale in the throat is scraped off by the three-blade holder 420, the amount of scale is reduced. As the three-blade holder 420 scrapes off the scale, the dissolving liquid comes into full contact with the scale, improving the dissolution efficiency and shortening the time required for the dissolving liquid to dissolve.

[0036] Please see Figures 1 to 2 The sewage inflow pipe 100 includes a sewage inflow pipe 110 and a first connecting flange 120. A first drain pipe 210 is fixedly connected to the lower side of the sewage inflow pipe 110. The sewage inflow pipe 110 is fixedly connected to the flange inlet of the ejector mechanism 200 through the first connecting flange 120. A valve is installed on the sewage inflow pipe 110. The sewage inflow pipe 110 and the flange inlet of the ejector mechanism 200 are fixedly connected through the first connecting flange 120, and sewage flows into the ejector mechanism 200 from the sewage inflow pipe 110. When cleaning the scale in the throat of the ejector mechanism 200, the valve on the sewage inflow pipe 110 is closed, and the sewage treatment operation is suspended.

[0037] Please see Figures 1 to 3The jetting mechanism 200 includes a flange inlet pipe 220, a flange outlet pipe 250, and an ozone intake pipe 280. The flange outlet pipe 250 is fixedly sleeved at the rear end of the flange inlet pipe 220. A tapered contraction section 230 is provided through the inside of the flange inlet pipe 220. The small-diameter outlet of the tapered contraction section 230 is the throat 240. A mixing straight section 260 and an anti-cone diffuser section 270 are provided at the front end inside the flange outlet pipe 250. The anti-cone diffuser section 270 is located at the rear end of the mixing straight section 260, and the throat 240 faces the small-diameter inlet of the anti-cone diffuser section 270. The ozone intake pipe 280 is fixedly connected to the upper side of the mixing straight section 260, and the first drain pipe 210 is fixedly connected to the lower side of the mixing straight section 260. A valve is provided on the ozone intake pipe 280. When the jet ejector mechanism 200 mixes wastewater and ozone, the wastewater passes through the conical contraction section 230, where the flow velocity increases and the pressure decreases. The wastewater is then ejected through the throat 240 of the jet ejector mechanism 200. According to Bernoulli's principle, a low-pressure zone is formed around the tip of the throat 240, drawing in ozone. The high-speed liquid flow tears apart the ozone column, forming numerous microbubbles, which are violently mixed in the strong turbulent field of the throat 240. The mixed flow enters the reverse conical diffusion section 270, where it decelerates and the pressure rises. During the pressure rise and residence time, the bubbles continue to diffuse and dissolve into the liquid phase, completing the mixing of wastewater and ozone. The mixed wastewater and ozone are then sent to the reaction tank through the wastewater outlet pipe 320 to participate in wastewater purification. When the jet ejector mechanism 200 is operating, the first drain pipe 210 and the inlet pipe 310 are closed, while the valves at the inlet of the wastewater inlet pipe 100, the outlet of the wastewater outlet pipe 320, and the ozone inlet of the jet ejector mechanism 200 are open.

[0038] Please see Figures 1 to 4 The dual-purpose top pipe 300 includes a dual-purpose top pipe 330 and a sealing flange plate 340. The sealing flange plate 340 securely seals the tail end of the dual-purpose top pipe 330. The front end of the dual-purpose top pipe 330 is fixedly connected to the flange outlet of the ejector mechanism 200. An inlet pipe 310 and a wastewater outlet pipe 320 are respectively fixedly connected to the upper side of the front end and the lower side of the rear end of the dual-purpose top pipe 330. The wastewater outlet pipe 320 is inclined upwards and backwards, while the inlet pipe 310 is inclined downwards and backwards. When the sealing flange plate 340 is opened, both ends of the dual-purpose top pipe 330 are opened, facilitating the installation of components at the tail end of the stepping axial flow impeller mechanism 400. The inlet pipe 310 is inclined to facilitate the flow of the dissolving liquid into the dual-purpose top pipe 330. The sewage outlet pipe 320 is inclined so that sewage flows out through the sewage outlet pipe 320. The water flow at the rear end of the dual-purpose top pipe 330 is reduced, which reduces the rotation of the stepping axial flow impeller mechanism 400 during the sewage treatment process, thereby reducing the interference of the stepping axial flow impeller mechanism 400 on the mixing of sewage and ozone.

[0039] Please see Figures 1 to 5The stepping axial flow impeller mechanism 400 also includes a rotating support structure 440 and a compression spring structure 450. The rotating support structures 440 are respectively disposed within the ejector mechanism 200 and the dual-purpose top tube 300. The axial flow impeller structure 410 slides through multiple rotating support structures 440, and the axial flow impeller structure 410 can slide along multiple rotating support structures 440. The compression spring structure 450 is disposed at the tail end of the axial flow impeller structure 410. The inner and outer rings of the compression spring structure 450 can rotate relative to each other. The outer ring of the compression spring structure 450 rotates with the axial flow impeller structure 410, and the return spring 430 presses the inner ring of the compression spring structure 450. In this embodiment, one rotating support structure 440 is disposed within the ejector mechanism 200, and two rotating support structures 440 are disposed within the dual-purpose top tube 300. The rotating support structure 440 is a hollow bracket, and the three-blade holder 420 is plate-shaped, which reduces the impact on the diameter of the inverse conical diffuser section 270 of the ejector mechanism 200, thereby reducing the influence of the stepping axial flow impeller mechanism 400 on the operation of the ejector mechanism 200. The compression spring structure 450 prevents the return spring 430 from rotating with the axial flow impeller structure 410, thus reducing the impact of the return spring 430 on the normal operation of the axial flow impeller structure 410.

[0040] Please see Figures 1 to 5 The axial flow impeller structure 410 includes an impeller shaft 411 and an axial flow impeller 412. The axial flow impeller 412 is fixedly sleeved on the impeller shaft 411 and is located between the inlet pipe 310 and the sewage outlet pipe 320. The axial flow impeller 412 is positioned between two rotating support structures 440 within the dual-purpose top pipe 300, placing it in a state similar to a simply supported beam. This reduces the radial runout of the axial flow impeller 412, making its rotation and stepping more stable. Furthermore, since the axial flow impeller 412 is located between the inlet pipe 310 and the sewage outlet pipe 320, the dissolved liquid flows into the dual-purpose top pipe 300 through the inlet pipe 310, allowing the axial flow impeller 412 to operate along with the flow of the dissolved liquid. When the inlet pipe 310 is closed, the sewage flows out through the sewage outlet pipe 320, reducing the effect of the sewage flow on the axial flow impeller 412, thereby reducing the kinetic energy consumption of the axial flow impeller 412 on the sewage flow, resulting in a decrease in sewage flow velocity, and achieving the purpose of reducing the interference of the axial flow impeller 412 on the mixing of sewage and ozone.

[0041] Please see Figures 1 to 6The rotating support structure 440 includes a rotating support sleeve 441, a fixed support rod 442, and a tightening screw 443. One fixed support rod 442 and two tightening screws 443 are evenly arranged around the rotating support sleeve 441. The fixed support rods 442 on the multiple rotating support structures 440 are respectively fixedly connected to the lower side of the inner wall of the jet ejector mechanism 200 and the dual-purpose top tube 300. The tightening screws 443 on the multiple rotating support structures 440 pass through the jet ejector mechanism 200 and the dual-purpose top tube 300 through threaded seals. The fixed support rod 442 supports the rotating support sleeve 441, and the tightening screws 443 press the rotating support sleeve 441 onto the fixed support rod 442. The axial flow impeller structure 410 slides through the rotating support sleeve 441. When installing the stepper axial flow impeller mechanism 400, three rotating support sleeves 441 are respectively fitted onto the impeller shaft 411. A three-blade tool holder 420 is installed at the front end of the impeller shaft 411. The impeller shaft 411 with the three-blade tool holder 420 is inserted into the ejector mechanism 200. The foremost rotating support sleeve 441 is pushed onto the fixed support rod 442 inside the ejector mechanism 200. The rotating support sleeve 441 is locked using a tightening screw 443. The latter two rotating support sleeves 441 are then pushed onto the dual-purpose top pipe 330. On the fixed support rod 442 inside, the rotating support sleeve 441 is locked with the tightening screw 443. Since the two rotating support sleeves 441 inside the dual-purpose top pipe 330 can slide along the impeller shaft 411, the position of the dual-purpose top pipe 330 is adjusted, and the flange outlet of the dual-purpose top pipe 330 and the jet mechanism 200 are connected and fixed. The return spring 430 is put on the rear end of the impeller shaft 411, the compression spring structure 450 is installed, and finally the tail end of the dual-purpose top pipe 330 is sealed with the sealing flange plate 340. The outer wall of the rotating support sleeve 441 is provided with a positioning groove. The fixed support rod 442 is composed of a support rod body 4421 and a positioning plate 4422. The positioning plate 4422 is fixedly connected to the top of the support rod body 4421 and is inserted into the positioning groove to position the rotating support sleeve 441. The tightening screw 443 is composed of a threaded rod part 4431 and a butterfly tightening part 4432. The butterfly tightening part 4432 is fixedly connected to the top of the threaded rod part 4431. The bottom end of the threaded rod part 4431 used on the jet ejector mechanism 200 passes through the jet ejector mechanism 200 and is pressed into the positioning groove of the rotating support sleeve 441. The bottom end of the threaded rod part 4431 used on the dual-purpose top pipe 330 passes through the dual-purpose top pipe 330 and is pressed into the positioning groove of the rotating support sleeve 441. The fixed support rod 442 and the tightening screw 443 are evenly arranged around the periphery of the rotating support sleeve 441 to form three pressing support points, thereby stabilizing the rotating support sleeve 441.

[0042] Please see Figures 1 to 7The compression spring structure 450 includes an outer sleeve 451, a bearing 452, an inner sleeve 453, and a tightening nut 454. The outer sleeve 451 is threaded onto the tail end of the axial flow impeller structure 410. The tightening nut 454 tightens the outer sleeve 451 onto the tail end of the axial flow impeller structure 410. The outer ring of the bearing 452 is fixedly inserted into the outer sleeve 451. The inner sleeve 453 is fixedly inserted into the inner ring of the bearing 452. The inner sleeve 453 is fitted onto the axial flow impeller structure 410. The rear end of the return spring 430 is pressed against the rotating support structure 440 at the rear end, and the front end of the return spring 430 is pressed against the side wall of the inner sleeve 453. When the compression spring structure 450 is installed, the outer sleeve 451 is fixedly sleeved on the outer ring of the bearing 452, and the inner sleeve 453 is inserted into the inner ring of the bearing 452. The inner sleeve 453 is sleeved on the impeller shaft 411. The inner sleeve 453 does not rotate with the impeller shaft 411. The front side wall of the inner sleeve 453 presses against the rear end of the return spring 430. The front end of the return spring 430 presses against the side wall of the rear rotating support sleeve 441. The middle part of the outer sleeve 451 is screwed onto the tail end of the impeller shaft 411 by threads, and then tightened and fixed by the tightening nut 454, thus fixing the outer sleeve 451 on the impeller shaft 411. The outer sleeve 451 rotates with the impeller shaft 411, reducing the influence of the return spring 430 on the rotation of the impeller shaft 411.

[0043] Please see Figures 1 to 8 An extension rod 455 is fixedly connected to the outer wall of the outer sleeve 451. A magnet 456 is installed at the top of the extension rod 455. An installation plate 350 is installed on the outer wall of the dual-purpose top pipe 300. A magnetic induction device 460 is installed on the installation plate 350. The magnetic induction devices 460 are arranged side by side. When the magnet 456 rotates with the outer sleeve 451 and approaches the magnetic induction device 460, the magnetic induction device 460 can sense the magnetic force of the magnet 456. The magnetic induction device 460 is set as an iron pointer, similar to a compass. The pointer is made of iron or uses a magnetic field detection sensor, such as a Hall sensor. The dual-purpose top pipe 330 is made of non-magnetic steel pipe. When the outer sleeve 451 drives the magnet 456 to gradually approach the magnetic induction device 460 via the extension rod 455, the magnetic induction device 460 displays the approach of the magnet 456, which can further reflect that the impeller shaft 411 and the three-way cutter holder 420 are rotating. When the magnetic induction device 460 does not detect the magnet 456 approaching or the magnet 456 moving away, it indicates that the impeller shaft 411 and the three-way cutter holder 420 are not rotating, and the three-way cutter holder 420 may be stuck. Reduce the flow rate of the dissolving liquid to make the three-way cutter holder 420 move away, and then increase the flow rate of the dissolving liquid again to reduce the occurrence of the three-way cutter holder 420 being stuck by scale and unable to continue working.

[0044] Please see Figures 1 to 9The three-way blade holder 420 includes a base 421, a mounting cylinder 422, an outer wall scraper 423, a flared scraper 424, and a throat scraper 425. The mounting cylinder 422 is fixedly sleeved on the front end of the axial flow impeller structure 410. The base 421 is fixedly connected to both sides of the rear end of the mounting cylinder 422. The outer wall scraper 423 is fixedly connected to the front side of the outer end of the base 421. The blades of the two outer wall scrapers 423 form an outward flare shape from back to front. The front end of the flared scraper 424 is fixedly connected to the outer wall of the front end of the mounting cylinder 422. The rear end is fixedly connected to the base 421. The blades of the two flared scrapers 424 form an inward V-shape from back to front. The throat scraper 425 is set on the side wall of the base 421. The blade surface of the outer wall scraper 423 is at a 25° angle to the tangential angle of the outer wall of the throat of the jet ejector mechanism 200. The outer wall scraper 423 gradually approaches the outer wall of the throat of the jet ejector mechanism 200 from back to front. The flared scraper 424 gradually extends into the interior of the throat of the jet ejector mechanism 200 from back to front. The throat scraper 425 gradually approaches the end of the throat of the jet ejector mechanism 200. As the three-blade holder 420 rotates, the blades of the two outer wall scrapers 423 flare outwards in a V-shape from back to front, gradually bringing the blades of the two outer wall scrapers 423 closer to the outer wall of the throat 240. The cutting surface of the outer wall scraper 423 forms a 25° angle with the tangential angle of the outer wall of the throat of the jetting mechanism 200, allowing the outer wall scraper 423 to maintain sufficient tangential force. The blades of the two flaring scrapers 424 flare inwards in a V-shape from back to front. The outer diameter of the front end of the two flaring scrapers 424 is small, and the outer diameter of the rear end is large, which can enlarge the inner diameter of the throat 240 that has shrunk due to scaling. The throat end scraper 425 scrapes away the scale at the end of the throat 240.

[0045] Please see Figures 1 to 10 The valves at the inlet of the sewage inflow pipe 100, the outlet of the sewage outflow pipe 320, and the ozone inlet of the jet ejector mechanism 200 are set as solenoid valves. Solenoid valves are also set at the first drain pipe 210 and the inlet pipe 310. The ozone inlet of the jet ejector mechanism 200 is connected to the ozone generator through the solenoid valve. The inlet pipe 310 is connected to the variable frequency booster pump through the solenoid valve. The inlet of the variable frequency booster pump is connected to the solution tank and the clean water tank through two two-position three-way valves respectively. The solenoid valves connected to the two first drain pipes 210 are then connected to the return ports of the solution tank and the clean water tank through two two-position three-way valves respectively.

[0046] When the ejector mechanism 200 is performing wastewater treatment, the solenoid valves on the first drain pipe 210 and the inlet pipe 310 are closed, while the solenoid valves at the inlet of the wastewater inflow pipe 100, the outlet of the wastewater outflow pipe 320, and the ozone inlet of the ejector mechanism 200 are open. This ensures that the dissolved liquid and clean water do not affect wastewater treatment.

[0047] When cleaning the scale in the throat of the jet injector, the solenoid valves at the inlet of the sewage inlet pipe 100, the outlet of the sewage outlet pipe 320, and the ozone inlet of the jet injector mechanism 200 are closed, while the solenoid valves at the first drain pipe 210 and the inlet pipe 310 are opened. The two-position three-way valve on the variable frequency booster pump is switched to connect the variable frequency booster pump to the solution tank. The two-position three-way valve on the first drain pipe 210 is switched to connect the first drain pipe 210 to the return port of the solution tank. The variable frequency booster pump works to send the solution through the inlet pipe 310 and return it through the first drain pipe 210.

[0048] After cleaning is completed, the two-position three-way valve on the variable frequency booster pump switches to connect the pump to the clean water tank. The two-position three-way valve on the first drain pipe 210 switches to connect the drain pipe 210 to the return port of the clean water tank. The variable frequency booster pump then pumps clean water through the inlet pipe 310, which then flows back through the first drain pipe 210. This reduces the residue of the dissolved solution in the sewage inlet pipe 100, the ejector mechanism 200, and the dual-purpose top pipe 300.

[0049] Specifically, the working principle of this water treatment ozone purification device is as follows: When cleaning the scale in the throat of the ejector, the solenoid valves at the inlet of the sewage inlet pipe 100, the outlet of the sewage outlet pipe 320, and the ozone inlet of the ejector mechanism 200 are closed, while the solenoid valves at the first drain pipe 210 and the inlet pipe 310 are opened. The two-position three-way valve on the variable frequency booster pump switches, connecting the variable frequency booster pump to the solution tank. The two-position three-way valve on the first drain pipe 210 switches, connecting the first drain pipe 210 to the return port of the solution tank. The variable frequency booster pump works to send the solution through the inlet pipe 310 into the dual-purpose top pipe 330, and the solution flows back through the first drain pipe 210. The solution flows in the dual-purpose top pipe 300, and the flow of the solution drives the axial flow impeller 412 to rotate. The impeller shaft 411 rotates with the axial flow impeller 412, and the impeller shaft 411 drives... The three-way tool holder 420 rotates, and simultaneously, the axial flow impeller 412, under the influence of the dissolved liquid flow, experiences axial thrust on the impeller shaft 411 in the direction of water flow. The impeller shaft 411 moves forward along the axial direction, and the three-way tool holder 420 moves with it. The return spring 430 is compressed by the compression spring structure 450 at the tail end of the impeller shaft 411, increasing the elastic force of the return spring 430. This elastic force balances the axial thrust of the water flow on the axial flow impeller structure 410, achieving the cutting action of the three-way tool holder 420. The flow rate of the dissolved liquid is gradually increased by the variable frequency booster pump. As the flow rate increases, the axial thrust on the axial flow impeller 412 in the direction of water flow also increases, causing the impeller shaft 411 to move forward axially. The return spring 430 is compressed, and its increased elastic force balances the increased thrust, achieving the purpose of gradual cutting. This causes the scale at the throat of the jet ejector mechanism 200 to be scraped off layer by layer. The blades of the two outer wall scrapers 423 are arranged in an outward V-shape from back to front, so that the blades of the two outer wall scrapers 423 gradually approach the outer wall of the throat 240. The cutting surface of the outer wall scraper 423 is at a 25° angle to the tangential angle of the outer wall of the throat of the jet mechanism 200, so that the outer wall scraper 423 can maintain sufficient tangential force. The blades of the two flared scrapers 424 are arranged in an inward V-shape from back to front. The outer diameter of the front end of the two flared scrapers 424 is small and the outer diameter of the rear end is large, which can make the inner diameter of the throat 240, which has been reduced due to scale buildup, expand again. The throat end scraper 425 scrapes off the scale at the end of the throat 240. The dissolving solution helps to minimize the scale in the throat of the ejector mechanism 200, thereby reducing the impact of the scale on the operation of the ejector mechanism 200. Firstly, it can extend the interval between manual cleaning and reduce the number of manual cleanings. Secondly, since some of the scale in the throat is scraped off by the three-blade holder 420, the amount of scale is reduced. As the three-blade holder 420 scrapes off the scale, the dissolving solution comes into full contact with the scale, improving the dissolution efficiency and shortening the time required for the dissolving solution to dissolve.

[0050] When the outer sleeve 451 drives the magnet 456 to gradually approach the magnetic induction device 460 via the extension rod 455, the magnetic induction device 460 displays the approach of the magnet 456, which can further reflect that the impeller shaft 411 and the three-way cutter holder 420 are rotating. When the magnetic induction device 460 does not detect the magnet 456 approaching or the magnet 456 moving away, it indicates that the impeller shaft 411 and the three-way cutter holder 420 are not rotating, and the three-way cutter holder 420 may be stuck. Reduce the flow rate of the dissolving liquid to make the three-way cutter holder 420 move away, and then increase the flow rate of the dissolving liquid again to reduce the occurrence of the three-way cutter holder 420 being stuck by scale and unable to continue working.

[0051] When the jet ejector mechanism 200 is performing wastewater treatment, the solenoid valves on the first drain pipe 210 and the inlet pipe 310 are closed, while the solenoid valves at the inlet of the wastewater inlet pipe 100, the outlet of the wastewater outlet pipe 320, and the ozone inlet of the jet ejector mechanism 200 are opened, so that the dissolved liquid and clean water do not affect the wastewater treatment. At this time, the elastic force of the return spring 430 moves backward and returns to its original position through the compression spring structure 450, the axial flow impeller 412, and the three-way cutter holder 420. The wastewater flows out through the wastewater outlet pipe 320. The axial flow impeller 412 is located at the rear end of the wastewater outlet pipe 320, which reduces the effect of the wastewater flow on the axial flow impeller 412, thereby reducing the kinetic energy consumption of the axial flow impeller 412 on the wastewater flow and causing the wastewater flow velocity to decrease. This achieves the purpose of reducing the interference of the axial flow impeller 412 on the mixing of wastewater and ozone.

[0052] It should be noted that the specific models and specifications of the magnetic field detection sensor, solenoid valve, ozone generator, variable frequency booster pump, and two-position three-way valve need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.
