Description

Technical Field

[0001] This invention relates to the field of water treatment system technology, specifically a multi-stage reverse osmosis water treatment system. Background Technology

[0002] During water treatment, we need to settle and filter the water. In current water treatment equipment, scale often forms. Since it is inside the equipment, it is inconvenient for staff to clean it. There is a water treatment device with scale removal function (patent number: CN 213266040 U) that uses a brush to clean scale. Although it can remove some scale to a certain extent, it cannot clean most of the scale. The main reason is that the position of the brush cannot be adjusted as needed, that is, the working range cannot be adjusted, which limits the scope of use. There is also a water treatment device that is easy to clean scale (patent number: CN 217230413U) that uses a stirring mechanism and cleaning liquid for scale removal. This method can only dissolve and clean the surface scale and cannot clean the internal scale. At the same time, this device also has the following problems: (1) the scale cleaning is incomplete and there is no self-cleaning function; (2) it cannot speed up water treatment, which is time-consuming and laborious.

[0013] The cleaning mechanism includes a brush plate, which is connected to a pressurizing mechanism via a pipe. The brush plate is mounted on a partition B, and a collection box is mounted on one side of the brush plate. The collection box is slidably mounted on a partition C, and the outer shell is provided with an opening groove for the collection box to move.

[0014] A second air inlet and a second air outlet are provided on the lower side between the sealing sleeve A and the sealing sleeve B. A third air inlet and a third air outlet are provided on the upper side of the sealing sleeve B. Control valves are installed on the second air inlet, the second air outlet, the third air inlet, and the third air outlet. The second air inlet and the third air outlet are connected to a pressurizing mechanism through pipes.

[0015] Press the start button on the control panel to start the device. Add an appropriate amount of liquid through the filling port A. The liquid is sent to the water storage bag through the first water inlet and the pipeline. The liquid flow is controlled by the first control valve. Add the liquid to be treated through the filling port B. The liquid to be treated is sent to the settling tank for settling through the pipeline.

[0016] The drive motor drives the active dial to rotate, the active dial drives the grooved wheel to rotate by one unit angle, the grooved wheel drives the first transmission shaft to rotate, and the first transmission shaft drives the active disc, cam and active lever to rotate synchronously respectively.

[0017] At the same time, when the active disc rotates, the electromagnet is energized, and the electromagnet telescopic rod pushes out the pawl to engage with the rotating plate, causing the rotating plate to rotate by one unit angle;

[0018] Simultaneously, when the cam rotates, the pressurizing mechanism begins to work. The specific working process is as follows: When the cam rotates to its maximum stroke, it presses the piston rod to move and compresses the first return spring. The piston rod compresses the water storage bag on one side of the piston cylinder, so that the liquid in the water storage bag is transported to the spray nozzle and pressurizing chamber through the first outlet. When the cam completes its maximum stroke, the first return spring will be released. The first return spring pushes the piston rod to move in the opposite direction. The piston rod compresses the other side chamber of the piston cylinder, so that the compressed air in the other side chamber is transported to the pressurizing chamber, the air jet, the sealing sleeve A, and the sealing sleeve B through the first air outlet and the pipeline. The second control valve realizes segmented on / off control.

[0019] After the liquid settles in the settling tank for a period of time, a certain amount of impurities will be generated at the bottom of the settling tank. The remaining liquid is sent to the pressurization chamber through the pipeline. When the pressurization chamber is pressurized by the pressurization mechanism, the liquid pressure in the pressurization chamber increases and is transported to the spray nozzle through the pipeline. By rotating the rotating plate at a unit angle, the spray nozzle sprays the liquid sequentially onto reverse osmosis membranes A, B, C, and D. Through the gradually increasing filtration effect of reverse osmosis membranes A, B, C, and D, the liquid is filtered to different degrees to meet different application requirements. At the same time, reverse osmosis membranes A, B, C, and D can separate, purify, and remove bacteria from the liquid. Due to the pressurized spraying of the liquid, the liquid filtration speed can be accelerated to a certain extent, forming the first accelerated filtration.

[0020] Simultaneously, the active lever drives the reciprocating gear, which meshes with the toothed plate. The reciprocating gear, through the first boss and the first waist hole, drives the vibrating plate to continuously rotate forward and backward within a certain angle, generating vibration. The vibrating plate drives the rotating plate to vibrate. It should be noted that in this state, the electromagnet is de-energized, the electromagnet telescopic rod retracts, and the pawl, under the action of the second torsion spring, will not mesh with the rotating plate. The rotating plate is completely controlled by the vibrating plate and vibrates continuously following the vibrating plate. Through the above design, the filtration speed of the liquid can be accelerated, forming a second accelerated filtration. At the same time, a cleaning mechanism is designed in combination with the above. Through the reciprocating vibration of the rotating plate, the brush plate contacts the reverse osmosis membrane D, brushing the impurities at the position of the reverse osmosis membrane D into the collection box, and then blowing them into the collection box through the upper jet nozzle.

[0021] The liquid filtered sequentially through reverse osmosis membranes A, B, C, and D is transported to the outlet via a liquid guide tube and pipeline.

[0022] During the aforementioned liquid treatment process, scale and impurities easily accumulate in the settling tank, necessitating cleaning. The cleaning mechanism then commences operation, with the specific process as follows: First, the pressurizing mechanism pressurizes the lower chamber of reciprocating plate A through the second air inlet. Reciprocating plate A compresses the third return spring on guide column A. Reciprocating plate A drives the rotating shaft to rotate via the connecting rod assembly. The rotating shaft then drives the telescopic sleeve A to rotate, which in turn drives telescopic sleeves B and C to rotate, bringing the cleaning plate into contact with the surface of the settling tank. The first cleaning motor drives the sealing sleeves A and B to rotate, which in turn drives the cleaning plate and spiral agitator on telescopic sleeve C to rotate, thus cleaning and agitating the settling tank. In the above design, the cleaning plate and spiral agitator... The cleaning plate and the spiral stirring blade are controlled by different methods. The cleaning plate is controlled by the rotation of the reciprocating plate A, and the reciprocating plate A and the lower side of the reciprocating plate A are set up with the same structure. In order to facilitate cleaning different positions of the settling tank, the telescopic sleeves A, B, and C are controlled by air pressure. The specific working process is as follows: the pressurizing mechanism pressurizes the internal chamber and the first air pressure channel of the telescopic sleeve C through the pipeline to control the extension length of the telescopic sleeves A, B, and C. The telescopic sleeve C controls the extension length of the cleaning plate and the spiral stirring blade to clean and stir different positions of the settling tank. After completing the above work, the settling is reset by the limiting spring A, etc., so as to facilitate the cyclic operation.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] 1. Multiple accelerated filtration and reverse osmosis settings cater to various applications. When the pressurization chamber is pressurized by the pressurization mechanism, the liquid pressure inside increases and is transported to the spray nozzle through the pipeline. The spray nozzle, through unit angle rotation of the rotating plate, sequentially sprays the liquid onto reverse osmosis membranes A, B, C, and D. These membranes can perform separation, reverse osmosis, purification, and bacterial removal on the liquid. Due to the pressurized spraying, the liquid filtration speed is accelerated to a certain extent, forming the first accelerated filtration. The active lever drives the reciprocating gear, which meshes with the toothed plate. The reciprocating gear, through the first boss and the first waist hole, drives the vibrating plate to continuously rotate forward and backward within a certain angle, creating vibration. The vibrating plate drives the rotating plate to vibrate, further accelerating the liquid filtration speed, forming the second accelerated filtration.

[0025] 2. The cleaning mechanism can clean impurities in different locations, meeting the needs of various applications. The pressurizing mechanism pressurizes the lower chamber of reciprocating plate A through the second air inlet. Reciprocating plate A compresses the third return spring on guide column A. Reciprocating plate A drives the rotating shaft to rotate via the connecting rod assembly. The rotating shaft drives the telescopic sleeve A to rotate. Telescopic sleeve A drives telescopic sleeves B and C to rotate, bringing the cleaning plate into contact with the surface of the settling tank. The first cleaning motor drives the sealing sleeves A and B to rotate. The sealing sleeves A and B drive the cleaning plate and spiral agitator on telescopic sleeve C to rotate, cleaning and agitating the settling tank. In the above design, the cleaning plate and spiral agitator are controlled differently. The cleaning plate is controlled by the rotation of reciprocating plate A, and the spiral agitator... The rotation of the plate is controlled by the reciprocating plate A, and the reciprocating plate A and its lower side have the same structure. To facilitate cleaning different parts of the settling tank, the telescopic sleeves A, B, and C are controlled by air pressure. The specific working process is as follows: The pressurizing mechanism pressurizes the internal chamber and the first air pressure channel of the telescopic sleeve C through the pipeline to control the extension length of the telescopic sleeves A, B, and C. The telescopic sleeve C controls the extension length of the cleaning plate and the spiral stirring blades to clean and stir different parts of the settling tank. After completing the above work, the plate is reset by the limiting spring A, etc., to facilitate cyclic operation.

[0026] 3. Equipped with a pressurizing mechanism, requiring no external equipment. When the cam rotates, the pressurizing mechanism begins operation. The specific working process is as follows: When the cam rotates to its maximum stroke, it presses the piston rod to move and compresses the first return spring. The piston rod compresses the water storage bag on one side of the piston cylinder, causing the liquid in the water storage bag to be transported through the first outlet to the spray nozzle and pressurizing chamber. When the cam completes its maximum stroke, the first return spring is released, pushing the piston rod to move in the opposite direction. The piston rod compresses the other chamber of the piston cylinder, causing compressed air from the other chamber to be transported through the first air outlet and pipeline to the pressurizing chamber, air jet, sealing sleeve A, and sealing sleeve B. The second control valve enables segmented on / off control. Through the above design, liquid pressurization and auxiliary cleaning mechanisms for impurity removal can be achieved.

[0058] At the same time, when the active disk 55 rotates, the electromagnet 54 is energized, and the telescopic rod of the electromagnet 54 pushes out the pawl 53 to engage with the rotating plate 5, and drives the rotating plate 5 to rotate by one unit angle.

[0059] Simultaneously, when cam 51 rotates, the pressurizing mechanism begins to work. The specific working process is as follows: When cam 51 rotates to its maximum stroke, it presses piston rod 72 to move and compresses the first return spring. Piston rod 72 compresses the water storage bag 7 on one side of piston cylinder 71, so that the liquid in the water storage bag 7 is transported to the spray nozzle 42 and pressurizing chamber 4 through the first outlet. When cam 51 has rotated to its maximum stroke, the first return spring will be released. The first return spring pushes piston rod 72 to move in the opposite direction. Piston rod 72 compresses the other side chamber of piston cylinder 71, so that the compressed air in the other side chamber is transported to the pressurizing chamber 4, spray nozzle 41, sealing sleeve A2, and sealing sleeve B21 through the first air outlet and pipeline, and the segmented on / off control is achieved through the second control valve.

[0060] After the liquid settles in the settling tank 14 for a period of time, a certain amount of impurities will be generated at the bottom of the settling tank 14. The remaining liquid is sent to the pressurizing chamber 4 through the pipeline. When the pressurizing chamber 4 is pressurized by the pressurizing mechanism, the liquid pressure in the pressurizing chamber 4 increases and is transported to the spray nozzle 42 through the pipeline. By rotating the rotating plate 5 by a unit angle, the spray nozzle 42 sprays the liquid sequentially onto the reverse osmosis membranes A56, B561, C562, and D563. Through the gradually increasing filtration effect of the reverse osmosis membranes A56, B561, C562, and D563, the liquid is filtered to different degrees to meet different application requirements. At the same time, the reverse osmosis membranes A56, B561, C562, and D563 can separate, purify, and remove bacteria from the liquid. Due to the pressurized spraying of the liquid, the liquid filtration speed can be accelerated to a certain extent, forming the first accelerated filtration.

[0061] Simultaneously, the active lever 58 drives the reciprocating gear 62, which, through the first boss and the first waist hole, drives the vibrating plate 52 to continuously rotate forward and backward within a certain angle, generating vibration. The vibrating plate 52 drives the rotating plate 5 to vibrate. It should be noted that in this state, the electromagnet 54 is de-energized, the electromagnet 54 telescopic rod retracts, and the pawl 53, under the action of the second torsion spring, will not engage with the rotating plate 5. The rotating plate 5 is completely controlled by the vibrating plate 52 and vibrates continuously following the vibrating plate 52. Through the above design, the filtration speed of the liquid can be accelerated, forming a second accelerated filtration. At the same time, a cleaning mechanism is designed in combination with the above. Through the reciprocating vibration of the rotating plate 5, the brush plate 8 contacts the reverse osmosis membrane D563, brushing the impurities at the position of the reverse osmosis membrane D563 into the collection box 19, and then blowing them into the collection box 19 through the upper jet port 41.

[0062] The liquid filtered sequentially through reverse osmosis membranes A56, B561, C562, and D563 is transported to the outlet 132 via a liquid guide tube 57 and a pipeline.

[0063] During the aforementioned liquid treatment process, scale and impurities easily accumulate in the settling tank 14, necessitating cleaning. The cleaning mechanism then commences operation, with the specific process as follows: First, the pressurizing mechanism pressurizes the lower chamber of the reciprocating plate A22 through the second air inlet. The reciprocating plate A22 compresses the third return spring on the guide column A27. The reciprocating plate A22 drives the rotating shaft 24 to rotate via the connecting rod assembly 26. The rotating shaft 24 drives the telescopic sleeve A32 to rotate, which in turn drives the telescopic sleeves B33 and C34 to rotate, bringing the cleaning plate 3 into contact with the surface of the settling tank 14. The first cleaning motor drives the sealing sleeves A2 and B21 to rotate, which in turn drives the cleaning plate 3 and the spiral stirring blade 31 on the telescopic sleeve C34 to rotate, thus cleaning and stirring the settling tank 14. In the above design, the cleaning plate 3 and the spiral stirring blade 31... The control methods for the agitator blades 31 are different. The cleaning plate 3 is controlled by the rotation of the reciprocating plate A22, and the spiral agitator blades 31 are controlled by the rotation of the reciprocating plate A22. The reciprocating plate A22 and the lower side structure of the reciprocating plate A22 are set up in the same way. In order to facilitate cleaning different positions of the settling tank 14, the telescopic sleeves A32, B33, and C34 are controlled by air pressure. The specific working process is as follows: the pressurizing mechanism pressurizes the internal chamber and the first air pressure channel of the telescopic sleeve C34 through the pipeline to control the extension length of the telescopic sleeves A32, B33, and C34. The telescopic sleeve C34 controls the extension length of the cleaning plate 3 and the spiral agitator blades 31 to clean and agitate different positions of the settling tank 14. After completing the above work, the settling tank 14 is reset by the limiting spring A32, etc., so as to facilitate the cyclic operation.

[0064] Working principle of the invention:

[0065] Press the start button on the control panel 1 to start the device. Add an appropriate amount of liquid through the filling port A13. The liquid is sent to the water storage bag 7 through the first water inlet and the pipeline. The liquid flow is controlled by the first control valve. Add the liquid to be treated through the filling port B131. The liquid to be treated is sent to the settling tank 14 for settling through the pipeline from the filling port B131.

[0066] The drive motor 18 drives the active dial 61 to rotate, the active dial 61 drives the grooved wheel 6 to rotate by one unit angle, the grooved wheel 6 drives the first transmission shaft to rotate, and the first transmission shaft drives the active disc 55, cam 51 and active lever 58 to rotate synchronously respectively.

[0067] At the same time, when the active disk 55 rotates, the electromagnet 54 is energized, and the telescopic rod of the electromagnet 54 pushes out the pawl 53 to engage with the rotating plate 5, and drives the rotating plate 5 to rotate by one unit angle.

[0068] Simultaneously, when cam 51 rotates, the pressurizing mechanism begins to work. The specific working process is as follows: When cam 51 rotates to its maximum stroke, it presses piston rod 72 to move and compresses the first return spring. Piston rod 72 compresses the water storage bag 7 on one side of piston cylinder 71, so that the liquid in the water storage bag 7 is transported to the spray nozzle 42 and pressurizing chamber 4 through the first outlet. When cam 51 has rotated to its maximum stroke, the first return spring will be released. The first return spring pushes piston rod 72 to move in the opposite direction. Piston rod 72 compresses the other side chamber of piston cylinder 71, so that the compressed air in the other side chamber is transported to the pressurizing chamber 4, spray nozzle 41, sealing sleeve A2, and sealing sleeve B21 through the first air outlet and pipeline, and the segmented on / off control is achieved through the second control valve.

[0069] After the liquid settles in the settling tank 14 for a period of time, a certain amount of impurities will be generated at the bottom of the settling tank 14. The remaining liquid is sent to the pressurizing chamber 4 through the pipeline. When the pressurizing chamber 4 is pressurized by the pressurizing mechanism, the liquid pressure in the pressurizing chamber 4 increases and is transported to the spray nozzle 42 through the pipeline. By rotating the rotating plate 5 by a unit angle, the spray nozzle 42 sprays the liquid sequentially onto the reverse osmosis membranes A56, B561, C562, and D563. Through the gradually increasing filtration effect of the reverse osmosis membranes A56, B561, C562, and D563, the liquid is filtered to different degrees to meet different application requirements. At the same time, the reverse osmosis membranes A56, B561, C562, and D563 can separate, purify, and remove bacteria from the liquid. Due to the pressurized spraying of the liquid, the liquid filtration speed can be accelerated to a certain extent, forming the first accelerated filtration.

[0070] Simultaneously, the active lever 58 drives the reciprocating gear 62, which, through the first boss and the first waist hole, drives the vibrating plate 52 to continuously rotate forward and backward within a certain angle, generating vibration. The vibrating plate 52 drives the rotating plate 5 to vibrate. It should be noted that in this state, the electromagnet 54 is de-energized, the electromagnet 54 telescopic rod retracts, and the pawl 53, under the action of the second torsion spring, will not engage with the rotating plate 5. The rotating plate 5 is completely controlled by the vibrating plate 52 and vibrates continuously following the vibrating plate 52. Through the above design, the filtration speed of the liquid can be accelerated, forming a second accelerated filtration. At the same time, a cleaning mechanism is designed in combination with the above. Through the reciprocating vibration of the rotating plate 5, the brush plate 8 contacts the reverse osmosis membrane D563, brushing the impurities at the position of the reverse osmosis membrane D563 into the collection box 19, and then blowing them into the collection box 19 through the upper jet port 41.

[0071] The liquid filtered sequentially through reverse osmosis membranes A56, B561, C562, and D563 is transported to the outlet 132 via a liquid guide tube 57 and a pipeline.

[0072] During the aforementioned liquid treatment process, scale and impurities easily accumulate in the settling tank 14, necessitating cleaning. The cleaning mechanism then commences operation, with the specific process as follows: First, the pressurizing mechanism pressurizes the lower chamber of the reciprocating plate A22 through the second air inlet. The reciprocating plate A22 compresses the third return spring on the guide column A27. The reciprocating plate A22 drives the rotating shaft 24 to rotate via the connecting rod assembly 26. The rotating shaft 24 drives the telescopic sleeve A32 to rotate, which in turn drives the telescopic sleeves B33 and C34 to rotate, bringing the cleaning plate 3 into contact with the surface of the settling tank 14. The first cleaning motor drives the sealing sleeves A2 and B21 to rotate, which in turn drives the cleaning plate 3 and the spiral stirring blade 31 on the telescopic sleeve C34 to rotate, thus cleaning and stirring the settling tank 14. In the above design, the cleaning plate 3 and the spiral stirring blade 31 are controlled in different ways, resulting in different cleaning... Plate 3 is rotated by reciprocating plate A22, and spiral stirring blade 31 is rotated by reciprocating plate A22. The reciprocating plates A22 and A22 have the same structure on their lower sides. To facilitate cleaning different positions of the settling tank 14, telescopic sleeves A32, B33, and C34 are connected by pneumatic telescopic control of their lengths. The specific working process is as follows: The pressurizing mechanism pressurizes the internal chamber and the first air pressure channel of telescopic sleeve C34 through pipelines to control the extension length of telescopic sleeves A32, B33, and C34. The telescopic sleeve C34 controls the extension length of cleaning plate 3 and spiral stirring blade 31 to clean and stir different positions of the settling tank 14. After completing the above work, the settling tank 14 is reset by limiting spring A32, etc., to facilitate cyclic work. The spiral stirring blade 31 rotates to stir different positions inside the settling tank 14.
