Description

Technical Field

[0001] The invention relates to the technical field of wastewater purification, and in particular to a water purifier with an anti-scaling function. Background Art

[0002] As people's demand for healthy drinking water continues to grow, water purifiers have become an indispensable part of many homes and commercial places. However, in the long-term use of traditional water purifiers, the filter element is prone to accumulate various impurities, such as suspended particles, organic matter, microorganisms and other pollutants, which not only reduces the filtration efficiency, but also may affect the safety of water quality, especially the PP cotton filter element, which is used as the first line of defense to remove large particles of impurities in the water, such as sand, rust, suspended matter and other pollutants. The internal environment affects the filtration quality and water safety of the subsequent filter element.

[0003] In the existing water purifier filter cleaning, manual disassembly and cleaning or ultrasonic cleaning are usually adopted. Manual cleaning takes a long time and has low efficiency. In ultrasonic cleaning, cavitation effect is generated in the liquid through high-frequency vibration to form countless tiny bubbles. When these bubbles collapse, strong local shock waves are generated, thereby removing pollutants on the surface and inside of the PP cotton. It has the advantage of good deep cleaning effect. However, when cleaning the PP cotton filter element, it relies on the tiny shock waves generated by the bubble cavitation effect to act on the pollutants on the surface of the filter element. However, the high-frequency vibration generated by the ultrasonic wave will exert continuous mechanical stress on the PP cotton filter element, resulting in microcracks inside the fiber, and eventually causing fatigue fracture. The cleaning method is single, which reduces the service life of the PP cotton filter element. Summary of the invention

[0004] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides a water purifier with anti-scaling function.

[0005] A water purifier with anti-scaling function comprises a water purifier body, a filter cartridge is fixedly connected in the water purifier body, a motor is fixedly connected in the water purifier body, a rotating shaft is fixedly connected to the output shaft of the motor, a rotating ring is fixedly connected to the rotating shaft, the filter cartridge is slidably connected to a lifting frame, the rotating ring is in contact with the lifting frame, two upper and lower first corrugated pipes are fixedly connected in the filter cartridge, the first corrugated pipe is fixedly connected to the lifting frame, the filter cartridge is connected to a sewage discharge pipe, the sewage discharge pipe passes through the water purifier body, a PP cotton filter element for pre-filtration is arranged in the filter cartridge, and the PP cotton filter The core is located between the upper and lower first corrugated tubes, the filter cartridge is connected to an air pumping pipe, an inflation rod is slidably connected between the air pumping pipe and the lifting frame, an air inlet valve for one-way air intake is fixedly connected to the air pumping pipe, an air outlet valve for one-way exhaust is fixedly connected to the air pumping pipe, at least one microporous diffuser is fixedly connected to one side of the filter cartridge close to the upper first corrugated tube, one side of the filter cartridge is connected to a water outlet pipe, the other side of the filter cartridge is connected to a water inlet pipe, the water outlet pipe is connected to the main filter element pipeline of the water purifier body, and a sealing component for blocking the water inlet pipe and the water outlet pipe is arranged outside the filter cartridge.

[0006] Furthermore, the blocking component includes an electric push rod, which is fixed to the outside of the filter cartridge. The electric push rod is fixed to a blocking frame, which is used to control the opening and closing of the water inlet pipe and the water outlet pipe.

[0007] Furthermore, the water inlet pipe and the water outlet pipe are both slidably connected to the blocking frame, and the blocking frame has circular holes corresponding to the water inlet pipe and the water outlet pipe respectively. When the water inlet pipe and the water outlet pipe are misaligned with the corresponding circular holes, the water inlet pipe and the water outlet pipe are blocked, and the waste water retained in the filter cartridge cannot be discharged.

[0008] Furthermore, it also includes a spring, which is wound on the inflation rod. Both ends of the spring are respectively fixed to the filter cylinder and the lifting frame. The inflation rod is fixed with a clamping tooth, the blocking frame is fixed with an elastic telescopic rod, and the elastic telescopic rod is fixed with a pushing tooth for clamping the clamping tooth.

[0009] Furthermore, the upper side surface of the latching tooth is set as a plane, and the lower side surface of the latching tooth is set as an inclined surface.

[0010] Furthermore, a diffusion frame is also included. The diffusion frame is fixed in the filter cartridge and is located above the PP cotton filter element.

[0011] Furthermore, it also includes a pressure relief pipe, which is connected to the filter cartridge, connected to the second bellows, fixedly connected to a pressure relief valve, a return pipe connected between the second bellows and the filter cartridge, and fixedly connected to a one-way valve.

[0012] Furthermore, the pressure relief valve restricts the waste water from flowing from the filter cartridge into the second bellows in one direction, and the one-way valve restricts the waste water from flowing from the second bellows into the filter cartridge in one direction.

[0013] Beneficial effects of the present invention: The present invention drives the first bellows to move by rapid rotation of the rotating ring so that water flows rapidly between the PP cotton filter elements. During the flow of water, gas is injected into the filter cartridge to generate microbubbles through cooperation with the inflation rod, thereby achieving gentle and rapid cleaning of the PP cotton filter element. Compared with ultrasonic cleaning, the PP cotton filter element can be flushed in a gentler manner by combining water flow and microbubbles, which can reduce damage to the PP cotton filter element while ensuring the cleaning effect. Compared with traditional water flushing, efficient cleaning can be completed with less water.

[0014] The present invention automatically pushes the inflation rod to reset itself after the PP cotton filter element is cleaned through the cooperation of the spring and the inflation rod, thereby ensuring the sustainable use of the inflation rod; and through the cooperation of the latching tooth and the pushing tooth, the inflation rod is automatically locked after the inflation rod completes one inflation of the filter cartridge, thereby preventing the spring from pushing the inflation rod to reset itself, causing the lifting frame to repeatedly push the inflation rod, repeatedly inflating the inside of the filter cartridge and affecting the cleaning quality of the PP cotton filter element.

[0015] When the PP cotton filter element is seriously clogged, the present invention temporarily stores waste water through the second bellows to achieve an overpressure protection effect, thereby avoiding overpressure deformation of the filter cartridge due to serious clogging of the PP cotton filter element when the filter cartridge is cleaning the PP cotton filter element.

DETAILED DESCRIPTION

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Embodiment 1: A water purifier with anti-scaling function, such as Figure 1-Figure 6As shown, it includes a water purifier body 101, the lower left part of the water purifier body 101 is set as a main filter element for post-filtering wastewater, a filter cartridge 102 is fixedly connected to the water purifier body 101, a motor 103 is fixedly connected to the water purifier body 101, the output shaft of the motor 103 is fixedly connected to a rotating shaft 104, the rotating shaft 104 is rotatably connected to the shell of the water purifier body 101, and a rotating ring 105 is fixedly connected to the middle part of the rotating shaft 104, so that one side of the rotating ring 105 is high and the other side is low, and the right side of the filter cartridge 102 slides in the up and down direction. The filter cartridge 102 is connected to a lifting frame 106, and the rotating ring 105 is in contact with the lifting frame 106, so that when the rotating ring 105 rotates, the lifting frame 106 can be driven to intermittently move up and down. The filter cartridge 102 is fixedly connected with two upper and lower first bellows 107, and the first bellows 107 is fixedly connected to the lifting frame 106. When the lifting frame 106 falls downward, the first bellows 107 on the lower side is stretched and the first bellows 107 on the upper side is compressed. The lower side of the filter cartridge 102 is connected to a sewage discharge pipe 108, and the sewage discharge pipe 108 passes through the water purifier body 101. The filter cartridge 102 02 is provided with a PP cotton filter element 109 for pre-filtering wastewater, and the PP cotton filter element 109 is located between the upper and lower first corrugated tubes 107. The upper right part of the filter cartridge 102 is connected with an air pumping pipe 110, and an air charging rod 111 is slidably connected between the air pumping pipe 110 and the lifting frame 106 along the up and down direction. An air inlet valve 112 is fixedly connected to the middle of the right side of the air pumping pipe 110, and the air inlet valve 112 is used for one-way air intake. An air outlet valve 113 is fixedly connected to the lower side of the air pumping pipe 110, and the air outlet valve 113 is used for one-way exhaust. Two microporous diffusers 114 are fixedly connected to one side of the first corrugated tube 107, the left side of the filter cartridge 102 is connected to a water outlet pipe 115, and the right side of the filter cartridge 102 is connected to a water inlet pipe 116. Wastewater enters the filter cartridge 102 through the water outlet pipe 115, and is pre-purified by the PP cotton filter element 109 to mainly remove larger particulate matter, such as mud, rust, suspended matter, etc., which can increase the service life of the main filter element of the water purifier body 101, and then is discharged through the water outlet pipe 115, and the water outlet pipe 115 is connected to the main filter element pipeline of the water purifier body 101.

[0032] like Figure 7 and Figure 8As shown, it also includes an electric push rod 201, which is fixedly connected to the outside of the filter cartridge 102. The pushing part of the electric push rod 201 is fixedly connected to the blocking frame 202. The water inlet pipe 116 and the water outlet pipe 115 are both slidably connected to the blocking frame 202. The left and right sides of the blocking frame 202 are respectively provided with circular holes corresponding to the water inlet pipe 116 and the water outlet pipe 115. When the water inlet pipe 116 and the water outlet pipe 115 are misaligned with the corresponding circular holes, the water inlet pipe 116 and the water outlet pipe 115 are both blocked, and the waste water retained in the filter cartridge 102 cannot be discharged. Under the up and down action of the upper and lower first corrugated tubes 107, the waste water retained in the filter cartridge 102 moves up and down, thereby cleaning the PP cotton filter element 109.

[0033] When the water purifier body 101 is purifying normally, waste water (concentrated water that is not filtered and cannot reach the reference standard) enters the filter cartridge 102 through the outlet pipe 115, passes through the PP cotton filter element 109 for pre-purification, and then is discharged into the main filter element pipeline of the water purifier body 101 through the outlet pipe 115 for post-purification. After multi-stage filtration, pure water that finally reaches the reference standard is finally obtained. The purifier stops purifying at regular intervals to self-clean the PP cotton filter element 109 to prevent scaling of the PP cotton filter element 109. The specific operation is as follows: The electric push rod 201 is started to drive the blocking frame 202 to move backward, and the water inlet pipe 116 and the water outlet pipe 115 of the filter cartridge 102 are closed, so that some waste water remains in the filter cartridge 102. The motor 103 is started, and the output shaft of the motor 103 drives the rotating shaft 104 to rotate rapidly, and the rotating shaft 104 drives the rotating ring 105 to rotate rapidly, thereby pushing the lifting frame 106 to move up and down continuously. When the lifting frame 106 moves upward, the first bellows 107 on the upper side is stretched, and the first bellows 107 on the lower side is compressed. , so that the water is squeezed into the first bellows 107 on the upper side, and the water in the first bellows 107 on the lower side is squeezed out; conversely, when the lifting frame 106 moves downward, the first bellows 107 on the upper side is compressed, and the first bellows 107 on the lower side is stretched, so that the water is squeezed into the first bellows 107 on the lower side, and the water in the first bellows 107 on the upper side is squeezed out; this reciprocates, and the water in the filter cartridge 102 continuously acts on the PP cotton filter element 109 up and down, thereby achieving the effect of quickly flushing the PP cotton filter element 109.

[0034] Initially, external gas enters the air pumping pipe 110 through the air inlet valve 112. In the above process, when the lifting frame 106 moves downward for the first time, it pushes the inflation rod 111 to move downward, so that the gas in the air pumping pipe 110 is unidirectionally injected into the wastewater in the filter cartridge 102 through the air outlet valve 113. The air is wrapped by the water flow and continuously moves up and down in the filter cartridge 102. When the bubbles pass through the microporous diffuser 114, these bubbles are acted upon by the microporous diffuser 114 and are decomposed into micro bubbles in the water flow. When the micro bubbles collide with the PP cotton filter element 109, the bubbles burst, and the pressure inside the bubbles is rapidly released when they burst, generating a local high-pressure shock wave. The micro bubbles are The local high pressure generated during the explosion can effectively loosen and remove stubborn dirt attached to the PP cotton filter element 109. Under the shear force generated by the combined action of bubbles and water flow, the pollutants attached to the PP cotton filter element 109 can be quickly peeled off, and the high-frequency vibration of the ultrasonic wave is avoided from exerting continuous mechanical stress on the PP cotton filter element 109, thereby preventing microcracks from appearing inside the fibers of the PP cotton filter element 109 and causing fatigue fracture, thereby increasing the service life of the PP cotton filter element 109. After the flushing of the PP cotton filter element 109 is completed, the wastewater mixed with other pollutants or impurities is discharged through the sewage discharge pipe 108, completing the flushing of the PP cotton filter element 109 and preventing scaling.

[0035] In summary, the first bellows 107 is driven to move by the rapid rotation of the rotating ring 105 so that the water flows rapidly through the PP cotton filter element 109. During the flow of water, gas is injected into the filter cartridge 102 through cooperation with the inflation rod 111 to generate microbubbles, thereby achieving gentle and rapid cleaning of the PP cotton filter element 109. Compared with ultrasonic cleaning, the PP cotton filter element 109 can be flushed in a gentler manner by combining water flow and microbubbles, which can reduce damage to the PP cotton filter element 109 while ensuring the cleaning effect. Compared with traditional water flushing, efficient cleaning can be completed with less water.

[0036] Embodiment 2: Based on embodiment 1, Figure 8-Figure 10 As shown, it also includes a spring 301, which is wound around the outside of the inflation rod 111. The upper and lower ends of the spring 301 are respectively fixed to the lifting frame 106 and the filter cartridge 102. A latch tooth 302 is fixed to the lower front side of the inflation rod 111. The upper side surface of the latch tooth 302 is set as a plane, and the lower side surface of the latch tooth 302 is set as an inclined surface. An elastic telescopic rod 304 is fixed to the right part of the blocking frame 202, and a pushing tooth 303 for clamping the latch tooth 302 is fixed to the rear end of the elastic telescopic rod 304. When the latch tooth 302 moves downward, the lower inclined surface of the latch tooth 302 is squeezed and matched with the pushing tooth 303.

[0037] When the electric push rod 201 is started, the electric push rod 201 drives the pushing tooth 303 and the elastic telescopic rod 304 to move backward through the blocking frame 202. When the inflation rod 111 slides downward for the first time, the spring 301 is compressed, and the inflation rod 111 drives the latch tooth 302 to move downward. The latch tooth 302 squeezes the pushing tooth 303 forward by the lower inclined surface, and the elastic telescopic rod 304 is compressed until the latch tooth 302 is completely aligned with the pushing tooth 303. The elastic telescopic rod 304 resets and drives the pushing tooth 303 to move backward and clamp the latch tooth 302, and the upper side plane of the latch tooth 302 makes it impossible for the latch tooth 302 to squeeze the pushing tooth 303. In this way, the inflation rod 111 is interlocked and fixed by the latch tooth 302 and the pushing tooth 303 when it moves downward for the first time. After locking, the PP cotton filter element 109 is cleaned.

[0038] When the cleaning of the PP cotton filter element 109 is stopped, the electric push rod 201 is controlled to reset. The electric push rod 201 drives the pushing tooth 303 and the elastic telescopic rod 304 to move forward through the blocking frame 202, so that the pushing tooth 303 is disengaged from the latching tooth 302. At this time, the spring 301 is reset to drive the inflation rod 111 to move upward, thereby driving the latching tooth 302 to move upward and reset.

[0039] In summary, through the cooperation of the spring 301 and the inflation rod 111, after the PP cotton filter element 109 is cleaned, the inflation rod 111 is automatically pushed to complete the reset, thereby ensuring the sustainable use of the inflation rod 111, and through the cooperation of the latch tooth 302 and the pushing tooth 303, after the inflation rod 111 completes one inflation of the filter cartridge 102, the inflation rod 111 is automatically locked to prevent the spring 301 from pushing the inflation rod 111 to reset, causing the lifting frame 106 to repeatedly push the inflation rod 111, repeatedly inflating the inside of the filter cartridge 102, and affecting the cleaning quality of the PP cotton filter element.

[0040] like Fig.11 As shown, a diffusion frame 401 is also included. The diffusion frame 401 is fixedly connected to the filter cartridge 102 , and the diffusion frame 401 is located above the PP cotton filter element 109 .

[0041] When the wastewater passes through the diffusion frame 401, it can diffuse circumferentially onto the PP cotton filter element 109, and the generated bubbles can also be evenly diffused onto the PP cotton filter element 109 through the diffusion frame 401, thus expanding the scope of cleaning the PP cotton filter element 109.

[0042] Embodiment 3: Based on embodiment 2, Fig.12 and Fig.13As shown, it also includes a pressure relief pipe 501, which is connected to the left side of the filter cartridge 102, and the top of the pressure relief pipe 501 is connected to the second bellows 502. A pressure relief valve 503 is fixedly connected to the upper part of the pressure relief pipe 501, and the pressure relief valve 503 limits the unidirectional flow of waste water from the filter cartridge 102 into the second bellows 502. A return pipe 504 is connected between the right side of the second bellows 502 and the filter cartridge 102, and a one-way valve 505 is fixedly connected to the return pipe 504, and the one-way valve 505 limits the unidirectional flow of waste water from the second bellows 502 into the filter cartridge 102.

[0043] If the PP cotton filter element 109 is severely clogged, when the upper first bellows 107 is squeezed downward to clean the PP cotton filter element 109, waste water enters the filter cartridge 102 and is difficult to be squeezed into the lower first bellows 107, resulting in increased water pressure in the filter cartridge 102. In order to prevent the filter cartridge 102 from deforming, the over-pressured waste water in the filter cartridge 102 is introduced into the second bellows 502 through the pressure relief pipe 501, and the second bellows 502 expands and stretches adaptively. The pressure relief valve 503 allows the waste water in the pressure relief pipe 501 to enter the second bellows 502 in one direction to prevent the waste water from flowing back.

[0044] When the first bellows 107 on the upper side is stretched upward, the waste water in the second bellows 502 is drawn into the return pipe 504 in one direction through the one-way valve 505, and then flows back into the filter cartridge 102 through the return pipe 504, and the second bellows 502 is reset, and this cycle repeats. When the PP cotton filter element 109 is severely clogged, the waste water can be temporarily stored in the second bellows 502 to achieve an overpressure protection effect, thereby preventing the filter cartridge 102 from being deformed by overpressure due to severe clogging of the PP cotton filter element 109 when cleaning the PP cotton filter element 109.

[0045] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
