Description

Technical Field

[0001] This invention relates to the field of pure water production and treatment technology, and in particular to a high-purity pure water production and treatment equipment. Background Technology

[0002] High-purity water has a wide range of important applications in many fields, including industrial production, laboratory research, and daily life. For example, in the manufacturing process of electronic chips, high-purity water is used to clean the chip surface to remove tiny impurity particles and chemical residues, ensuring the chip's performance and quality. In the biomedical field, pure water is the basic solvent for preparing various drugs and conducting biological experiments, and its purity directly affects the purity of the drugs and the accuracy of experimental results.

[0003] Existing pure water production and treatment equipment faces several pressing issues in the pure water preparation process. In the pretreatment stage, the removal of large particulate impurities and organic matter from the raw water is insufficient. Traditional pretreatment devices often have simple structures and single filtration methods, making it difficult to effectively intercept impurities of different particle sizes. This increases the burden on subsequent treatment stages and affects the overall efficiency of pure water production. For example, some pretreatment equipment uses only simple filter screens, which have limited ability to remove fine particles and some dissolved organic matter.

[0004] In the filtration process, it is difficult to balance the filtration efficiency and lifespan of filter components. As the usage time increases, impurities gradually accumulate on the surface of the filter components, leading to increased filtration resistance and decreased filtration speed. Moreover, most existing filter components cannot automatically clean the accumulated impurities, requiring regular manual disassembly and cleaning. This not only increases labor intensity but may also cause production interruptions, affecting the continuity of pure water supply.

[0005] Furthermore, existing equipment has shortcomings in impurity collection and treatment. The containers for collecting impurities are inconvenient to replace, and leaks are prone to occur during replacement, polluting the surrounding environment. Moreover, the connection between the containers and the equipment is not secure enough, and vibrations during operation may loosen it, affecting the normal collection of impurities.

[0014] As a further embodiment of the present invention, the collection assembly includes a waste bin, a fixed trapezoidal plate fixedly installed on one inner wall of the waste bin, two symmetrically arranged positioning grooves opened at the bottom of the waste bin, two symmetrically arranged positioning posts fixedly installed on the bottom inner wall of the pretreatment bin, the positioning posts engaging with the positioning grooves, a sliding baffle slidably connected to the outer wall of the pretreatment bin, a strip-shaped vertical hole opened on one side of the pretreatment bin, a connected rectangular groove opened on the top inner wall of the rectangular placement hole, the strip-shaped vertical hole communicating with the rectangular groove, a common L-shaped sliding plate slidably connected between the two inner walls of the rectangular groove, and a common fifth [unclear] between one side of the L-shaped sliding plate and one inner wall of the rectangular groove. A compression spring is included. A connecting crossbar is slidably connected inside the strip-shaped vertical hole. One end of the connecting crossbar is fixedly connected to one side of a sliding baffle. A triangular block is fixedly installed on the bottom side of the connecting crossbar. A fourth compression spring is provided between the top of the connecting crossbar and the top inner wall of the rectangular groove. The triangular block cooperates with an L-shaped sliding plate. Side strip blocks are fixedly installed on both inner walls of the rectangular placement hole. A common drain slope is fixedly installed between the two inner walls of the pretreatment box. The drain slope is sleeved on the outside of the filter cartridge. A rotating baffle is rotatably connected to one end of the drain slope. One end of the rotating baffle cooperates with the L-shaped sliding plate. One side of the rotating baffle cooperates with a fixed trapezoidal plate.

[0015] As a further embodiment of the present invention, a drainage hole is provided on one side of the bottom of the pretreatment box, a fixed partition is fixedly installed on one side of the bottom inner wall of the pretreatment box, the top of the fixed partition is fixedly connected to the bottom of the sewage discharge inclined plate, one side of the fixed partition abuts against one side of the waste box, and a drainage inclined plate is fixedly installed on the bottom inner wall of the pretreatment box.

[0016] The beneficial effects of this invention are as follows: After water enters the pretreatment tank through the inlet pipe, it pushes the top plate downwards, causing the filter plates to rotate. This allows the water to be dispersed and discharged through the drain strip outlet to the top of the filter plates. This design ensures that the water is evenly distributed on the filter plates, increasing the filtration area and improving the interception efficiency of large particulate impurities. Simultaneously, impurities remain at the top of the drain strip outlet for easy collection and treatment, effectively reducing the burden on subsequent treatment stages and laying a solid foundation for obtaining high-purity water.

[0017] The equipment employs a multi-stage filtration system with automatic cleaning. After passing through the primary filtration unit, water enters the secondary filtration unit. The filter cartridges in the secondary filtration unit perform a second, finer filtration, removing tiny particles and some dissolved impurities. Furthermore, an electric push rod drives a series of transmission mechanisms, enabling automatic rotation of the filter cartridges and automatic cleaning of the cartridges by the brushes. When the filter cartridge rotates 180 degrees, the filter screens on both sides are used alternately, ensuring continuous filtration efficiency. Simultaneously, the brushes move upwards under the drive of the lifting screw, cleaning the surface of the filter cartridges, removing impurities, and allowing them to slide down the drain plate into the waste bin. This prevents increased filtration resistance and decreased filtration speed due to impurity accumulation, thus improving the equipment's lifespan and pure water production efficiency.

[0018] The equipment is equipped with a comprehensive impurity collection system. The waste bin is securely connected to the pretreatment bin via a positioning slot and positioning post, ensuring stability during equipment operation. When the waste bin is full of impurities, a simple upward push will engage the waste bin with the sliding baffle, releasing the L-shaped sliding plate from restricting the rotating baffle. Simultaneously, the positioning slot and positioning post below the waste bin disengage, facilitating the horizontal removal of the waste bin for replacement. During replacement, the rotating baffle and drain ramp temporarily catch impurities, preventing leakage and environmental pollution. After a new waste bin is placed in, the sliding baffle moves downward, the triangular block resets, pushing the L-shaped sliding plate, causing the rotating baffle to fall into the waste bin for continued impurity collection. The operation is convenient and quick, improving production efficiency.

[0019] The entire system, from pretreatment to final pure water collection, operates with close coordination at each stage, forming a stable pure water production process. Pretreated water sequentially passes through a filtration tank, a reverse osmosis unit, and a deep desalination unit to progressively remove impurities and ions. The reverse osmosis unit, under high pressure, passes the water through a reverse osmosis membrane, producing mostly "primary pure water," with the concentrated water discharged. The deep desalination unit further removes trace ions, ultimately yielding high-purity pure water, which is collected in a pure water tank. This multi-stage treatment method ensures that the purity of the pure water meets the requirements of various fields, providing a reliable pure water supply for industrial production, laboratory research, and more.

[0022] 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. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0023] Reference Figures 1-14 The specific implementation method of a high-purity pure water production and treatment equipment is as follows: The main body of the equipment consists of a pretreatment tank 1, a raw water tank 3, a filter tank 5, a reverse osmosis unit 6, a pure water tank 7, and a deep desalination unit 8, forming a complete treatment chain. The pretreatment tank 1 is connected to the raw water tank 3 via pipelines. A stainless steel water pump 4 is installed between the raw water tank 3 and the filter tank 5 to achieve fluid transport. The filter tank 5 is connected to the reverse osmosis unit 6, and the reverse osmosis unit 6 is connected to the deep desalination unit 8 via dedicated pipelines. Finally, the pure water is stored in the pure water tank 7 after deep treatment.

[0024] In the internal structure of the pretreatment tank 1, two carbon steel fixed vertical plates 22 are symmetrically fixed to the inner walls on both sides. The two plates are arranged parallel to each other and a fixed horizontal plate 24 is welded to the top. A water storage component is installed on the top of the fixed horizontal plate 24: two sliding rectangular plates 21 are slidably connected to the fixed horizontal plate 24 through bottom slide rails. A first compression spring 23 is installed between one side of the sliding rectangular plate 21 and the inner wall of the pretreatment tank 1. A water inlet pipe 2 is welded to the middle of the top of the pretreatment tank 1, and its bottom opening is directly opposite the gap between the two sliding rectangular plates 21. When water flows in through the water inlet pipe 2, the water pressure pushes the sliding rectangular plates 21 to move to both sides, and the first compression spring 23 is compressed to form a buffer space, realizing automatic adjustment of the water inlet volume.

[0025] A drainage slot 19 is provided at the bottom of the fixed vertical plate 22. A push plate 60 is provided between the two plates, and four sets of symmetrically distributed protrusions 54 are welded to its bottom. Sliding blocks 53 are welded to both sides of the push plate 60, forming a sliding fit with the sliding grooves 20 provided on the side wall of the fixed vertical plate 22. A V-shaped baffle plate 32 is provided below the push plate 60. This plate is made of stainless steel, with circular vertical holes 33 inside, rubber strips glued to both ends, and a fixed rectangular plate 18 welded to its bottom. A primary filtration assembly is provided above the V-shaped baffle plate 32: two filter plates 30 are rotatably connected to the inner walls of both sides of the pretreatment box 1 through bearings, and a strip-shaped protrusion 31 is welded to the middle of one end of the filter plate 30. An arc-shaped fixing block 25 is welded to the inner wall of the pretreatment box 1, and a cylindrical cavity 29 is opened inside it. A sliding circular plate 27 is connected to the cylindrical cavity 29 through a bottom slide rail. A push rod 28 is welded to one end, and the push rod 28 forms an abutment with the strip-shaped protrusion 31 and the top of the filter plate 30. A second compression spring 26 is set between the other side of the sliding circular plate 27 and the inner wall of the cylindrical cavity 29. When the top plate 60 is pushed down by water pressure, the protrusion 54 presses the filter plate 30 to rotate, so that one end of the filter plate 30 is tightly attached to the bottom of the arc-shaped fixing block 25. The water flows through the drain strip 19 and is dispersed to the top of the filter plate 30. After preliminary filtration, it enters the next stage through the circular vertical hole 33.

[0026] A re-filtration assembly is installed inside the fixed rectangular plate 18: a semi-circular hole 34 is formed, and a middle baffle 74 is welded to the bottom.

An upper sliding semi-circular plate 80 is welded to the top of the lower sliding semi-circular plate 82. Nylon bristles 81 are bonded to the outer wall of the upper sliding semi-circular plate 80, and a semi-circular push block 79 is welded to the top of the upper sliding semi-circular plate 80. A hollow ring 72 is welded to the outer wall of the filter cartridge 57, and notches 71 are formed on both sides of its top. The middle baffle 74 has a first rectangular cutout 83 at the top and a second clearance groove 87 on one side. A connecting plate 85 is slidably connected inside, with a semi-circular sealing plate 84 welded to one side and a sealing baffle 86 welded to the other. The sealing baffle 86 is slidably connected to the second clearance groove 87. A sliding semi-circular top plate 73 is welded to the top, with a rectangular protrusion 77 welded to one end. The bottom of the fixed rectangular plate 18 has a first clearance groove 35 and a circular groove 38. A connecting column 36 slides through the circular groove 38, and a third compression spring 37 is installed between its top and the inner wall of the circular groove 38. The bottom is welded to the top of the sliding semi-circular top plate 73. When water flows through the semi-circular hole 34, the semi-circular sealing plate 84 controls the water flow path by moving up and down: when moving down, water flows through the outer gap of the semi-circular sealing plate 84 into the filter cartridge 57 near the fixed semi-circular bottom plate 78 for secondary filtration; when moving up, the semi-circular sealing plate 84 blocks the bottom of the fixed semi-circular top plate 75, pausing the filtration operation.

[0027] A transmission mechanism is installed at the bottom of the pretreatment box 1: a lower cylindrical tube 11 is welded to the inner wall of the bottom, connecting covers 12 are welded to both sides, and an upper cylindrical tube 13 is welded to the bottom of the middle baffle 74, which is located directly above the lower cylindrical tube 11 with a gap. An annular baffle 61 is rotatably fitted onto the outer walls of the connecting covers 12 and the lower cylindrical tube 11 via bearings. Two connecting rectangular plates 63 are welded to the inner wall of the baffle 61, and a rotating shaft 64 is welded between the two plates. A one-way gear 65 is fixed to the outer wall, and a second gear 66 meshes with the outer wall of the one-way gear 65. Rectangular blocks 70 are welded to both sides of the filter cartridge 57, and a side vertical rod 62 is welded to the bottom, with its bottom welded to the top of the annular baffle 61. The inner wall of the lower cylindrical tube 11 is rotatably connected to the first gear 69 via a mounting base. The internal thread of the first gear 69 passes through the lifting screw 55. The top of the lifting screw 55 sequentially passes through the lower sliding semicircular plate 82, the upper sliding semicircular plate 80, the sliding semicircular top plate 73, and the fixed rectangular plate 18. A horizontal plate 58 is welded to the top of the first gear 69, and a vertical rod 59 is welded to the top of the horizontal plate 58. The top of the vertical rod 59 is welded to the bottom of the pushing top plate 60. A protective shell 9 is welded to the outer wall of the pretreatment box 1. An electric push rod 56 is fixed inside, with its piston rod extending into the connecting cover 12. A second rack 68 is welded to the end of the rod, and a first rack 67 is welded to one end of the second rack 68. When the electric push rod 56 is activated, the piston rod drives the second rack 68 and the first rack 67 to move: the second rack 68 drives the second gear 66 to rotate, which drives the annular baffle 61 to rotate through the rotating shaft 64, thereby causing the filter cartridge 57 to rotate 180 degrees to achieve filter screen alternation; the first rack 67 drives the first gear 69 to rotate, which drives the lifting screw 55 to rise, so that the upper sliding semicircular plate 80 drives the brush bristles 81 to clean the filter cartridge 57, and at the same time releases the braking state of the sliding semicircular top plate 73, pushing the impurities to slide down along the sewage discharge inclined plate 41.

[0028] The impurity collection system includes a waste bin 10 made of high-density polyethylene. A trapezoidal plate 39 is welded to the inner wall of one side, and two positioning grooves 44 are formed at the bottom, engaging with positioning posts 43 welded to the inner wall of the bottom of the pretreatment bin 1. A sliding baffle 17 is connected to the outer wall of the pretreatment bin 1 via a slide rail. A strip-shaped vertical hole 48 is formed on one side, and a rectangular groove 49 is formed on the inner wall of the top of the rectangular placement hole 50, connecting the two. An L-shaped sliding plate 51 is connected to the rectangular groove 49 via a slide rail, and a fifth compression spring 52 is installed between one side of the L-shaped sliding plate 51 and the inner wall of the rectangular groove 49. A connecting crossbar 46 is slidably connected within the strip-shaped vertical hole 48, with one end welded to the sliding baffle 17, a triangular block 45 welded to one side of the bottom, and a fourth compression spring 47 installed between the top of the crossbar 51 and the inner wall of the top of the rectangular groove 49. Side strip blocks 40 are welded to the inner walls of both sides of the rectangular placement hole 50. A drain slope 41 is welded between the inner walls of both sides of the pretreatment box 1, which is fitted onto the outside of the filter cartridge 57. One end is connected to a rotating baffle 42 via a rotating shaft. One end of the rotating baffle 42 engages with an L-shaped sliding plate 51, and the other side abuts against a fixed trapezoidal plate 39. When the waste bin 10 is full, it is pushed upwards to disengage from the positioning post 43, causing the triangular block 45 to disengage from the L-shaped sliding plate 51. The fifth compression spring 52 pushes the L-shaped sliding plate 51 laterally, and the fixed trapezoidal plate 39 lifts the rotating baffle 42 to engage with the L-shaped sliding plate 51, preventing impurity leakage. After replacing the waste bin 10, the sliding baffle 17 moves downwards, causing the triangular block 45 to reset under the action of the fourth compression spring 47, pushing the L-shaped sliding plate 51 and causing the rotating baffle 42 to fall into the waste bin 10 for continued collection.

[0029] A drain hole 15 is provided on one side of the bottom of the pretreatment tank 1, and a fixed partition 14 is welded to one side of the bottom inner wall. The top of the partition is welded to the bottom of the sewage discharge inclined plate 41, and one side is in contact with the waste tank 10. A drainage inclined plate 16 is welded to the bottom inner wall to ensure smooth water discharge. This equipment achieves the interception of large particles, adsorption of organic matter, and removal of trace ions through the coordinated work of multi-stage filtration components. The transmission mechanism realizes automatic switching and cleaning of the filter screen, and the collection system ensures the sealed treatment of impurities. The overall structure is compact, the filtration efficiency is improved, and the maintenance cycle is extended.

[0030] Working principle: During use, water is sent into the pretreatment tank 1 through the inlet pipe 2. After pretreatment in the pretreatment tank 1, the water is sent into the raw water tank 3. The water pump 4 draws the water out of the inlet pipe 2 and into the filter tank 5. The water then enters the sand filter tank 5 to remove large particles and the carbon filter tank 5 to remove organic matter and residual chlorine, thus initially purifying the water. The pretreated water enters the reverse osmosis unit 6 and passes through the reverse osmosis membrane under high pressure. Most of the water becomes "primary pure water" and the concentrated water is discharged. The water produced by the reverse osmosis unit 6 enters the deep desalination unit 8 to further remove trace ions. Finally, the pure water enters the pure water tank 7, completing the entire pure water production process. After water enters the pretreatment tank 1 through the inlet pipe 2, it pushes the top plate 60 downward. At this time, the top plate 60 pushes the two filter plates 30 to rotate, pressing one end of the filter plate 30 against the bottom of the arc-shaped fixing block 25. At this time, the water is dispersed and discharged to the top of the two filter plates 30 through the two drain strip ports 19. After being filtered by the filter plates 30, it enters the top of the V-shaped baffle plate 32, and impurities remain on the top of the drain strip ports 19. Water is discharged through the interior of the circular vertical hole 33 to the interior of the semi-circular hole 34, and can also be fed in through the interior of the fixed semi-circular top plate 75. The size of the semi-circular sealing plate 84 is smaller than the size of the fixed semi-circular top plate 75, but larger than the size of the central hole of the fixed semi-circular top plate 75. When the semi-circular sealing plate 84 moves upward, it abuts against the bottom of the fixed semi-circular top plate 75 to prevent water from continuing to pass through. When the semi-circular sealing plate 84 moves downward, it can be conveyed downward through the gap around the semi-circular sealing plate 84, and filtered again through the side of the filter cartridge 57 near the fixed semi-circular bottom plate 78 before being discharged. Finally, it is sent to the next process through the drain hole 15. The electric push rod 56 can be activated. The piston rod of the electric push rod 56 drives the second rack 68 and the first rack 67 to move. The second rack 68 drives the second gear 66 to rotate. The second gear 66 drives the rotating shaft 64 to rotate. The rotating shaft 64 drives the connecting rectangular plate 63 to rotate. The connecting rectangular plate 63 drives the annular baffle 61 to rotate. The annular baffle 61 drives the side vertical rod 62 to rotate. The side vertical rod 62 drives the connecting rectangular block 70 to rotate. The connecting rectangular block 70 drives the filter cartridge 57 to rotate. The filter cartridge 57 rotates 180 degrees, so that the filter screens on both sides alternate to ensure filtration efficiency. At this time, the second rack 68 continues to drive the first rack 67 to move. The first rack 67 meshes with the first gear 69. The first gear 69 rotates, driving the lifting screw 55 to rise. The lifting screw 55 drives the internal lower sliding semicircular plate 82 and upper sliding semicircular plate 80 to move upward. The upper sliding semicircular plate 80 drives the bristles 81 to clean the filter cartridge 57. Since the notch 71 corresponds to the rectangular protrusion 77 at this time, the braking state of the sliding semicircular top plate 73 is released. The upper sliding semicircular plate 80 drives the semicircular push block 79 to move upward. The semicircular push block 79 lifts the sliding semicircular top plate 73 upward. The impurities on the surface of the upper sliding semicircular plate 80 slide out and slide down along the sewage discharge inclined plate 41. Furthermore, the sliding semi-circular top plate 73 drives the sealing baffle 86 and the connecting plate 85 to move upward. The connecting plate 85 drives the semi-circular sealing plate 84 to move upward. The semi-circular sealing plate 84 can temporarily close the fixed semi-circular top plate 75, temporarily stopping the filtration operation. The lifting screw 55 drives the connecting horizontal plate 58 to move upward. The connecting horizontal plate 58 drives the connecting vertical rod 59 to move upward. The connecting vertical rod 59 drives the pushing top plate 60 to move upward. The pushing top plate 60 drives the slider 53 to slide inside the trough 20, gradually blocking the drainage strip 19. The ash that enters will temporarily remain between the two fixed vertical plates 22 and will push the sliding rectangular plate 21 to move to both sides, leaving space. When the top plate 60 is pushed up, the protrusion 54 no longer presses down on the filter plate 30. The two filter plates 30 rotate, and the sliding circular plate 27 and the push rod 28 can extend under the elastic force of the second compression spring 26 to help the filter plate 30 rotate. The bottom side of the filter plate 30 abuts against the rubber pad at the top end of the V-shaped baffle 32, which can then be deformed to help the impurities on the surface slide off. The impurities on the side closer to the waste bin 10 slide directly into the interior of the waste bin 10, while the impurities on the side farther from the waste bin 10 slide off the surface of the drain slope 41 into the interior of the waste bin 10. At this time, the piston rod of the electric push rod 56 extends again to help the device reset. Due to the setting of the one-way gear 65, the rotating circular shaft 64 will not reverse at this time. When the waste bin 10 is full, it can be pushed upwards. The waste bin 10 pushes the sliding baffle 17 upwards, which in turn moves the connecting crossbar 46 and the triangular block 45 upwards. At this time, the triangular block 45 no longer presses against the L-shaped sliding plate 51. The L-shaped sliding plate 51 moves laterally under the elastic force of the fifth compression spring 52, and the positioning groove 44 and positioning post 43 below the waste bin 10 disengage, allowing the waste bin 10 to be pulled out laterally. At this time, the fixed trapezoidal plate 39 on one side of the waste bin 10 will rotate the baffle 42 towards... The rotating baffle 42 is temporarily engaged with the L-shaped sliding plate 51 to prevent it from falling. The rotating baffle 42 and the sewage discharge ramp 41 temporarily catch the impurities. At this time, the sliding baffle 17 is kept in place by hand so that the waste bin 10 can be pulled out horizontally normally. After the new waste bin 10 is put in, the sliding baffle 17 moves down and the triangular block 45 is reset under the elastic force of the fourth compression spring 47. The L-shaped sliding plate 51 is pushed to one side and the rotating baffle 42 falls into the interior of the waste bin 10 to continue collection.
