Description

Technical Field

[0001] This utility model relates to the field of chemical water treatment ultrafiltration and reverse osmosis technology, and in particular to a chemical water treatment ultrafiltration and reverse osmosis device. Background Technology

[0002] Ultrafiltration reverse osmosis (UOS) is an advanced water treatment technology developed to meet increasingly stringent water quality requirements for modern industrial wastewater discharge. Traditional filtration technologies are no longer sufficient to meet complex needs such as impurity removal and decolorization. UOS combines physical and semi-chemical processes to efficiently desalinate, decolorize, and purify water. Its unique functionality effectively removes dissolved impurities and organic matter from water, extending equipment lifespan while reducing energy consumption and maintenance costs, providing reliable technical support for industrial water treatment.

[0003] In the filtration process of ultrafiltration and reverse osmosis devices for chemical water treatment, the large particle size or physicochemical properties of the filter media can easily clog the filter cartridge pores, leading to a significant reduction in filtration efficiency or even complete stagnation. This phenomenon not only prolongs the lifespan of the filter cartridge but may also cause a decrease in the overall operating efficiency of the filtration system, affecting the stability and reliability of the entire water treatment system. Therefore, developing a filtration device design that can effectively solve this problem is crucial.

[0004] In response to this technical problem, this application proposes a chemical water treatment ultrafiltration reverse osmosis device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a chemical water treatment ultrafiltration reverse osmosis device that optimizes the water flow between filter element one and filter element two, prevents impurities from directly clogging the filter holes, significantly improves the filtration speed and stability of the two elements, enables rapid replacement, and significantly enhances maintenance efficiency and ease of operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A chemical water treatment ultrafiltration reverse osmosis device includes a filter chamber, a sealing door rotatably connected to the front end of the filter chamber, a connecting shell fixedly connected to the top of the filter chamber, an input pipe fixedly connected to the left end of the connecting shell, a fixing shell fixedly connected to the top of the connecting shell, a drive motor fixedly connected to the inner wall of the fixing shell, a transmission pipe and a transmission rod connected to the drive end of the drive motor via a stirring assembly, fixing blocks fixedly connected to the left and right sides of the bottom end of the connecting shell, a docking ring fixedly connected to the outer wall of each fixing block, a filter element connected to the inner wall of the docking ring via a disassembly assembly, and a discharge pipe fixedly connected to the bottom end of the connecting shell and penetrating the top of the filter chamber.

[0008] Furthermore, the stirring assembly includes a first bevel gear fixedly connected to the drive end of the drive motor, and a second bevel gear fixedly connected to the top of both the transmission tube and the transmission rod, wherein the first bevel gear and the second bevel gear are meshed together.

[0009] Furthermore, a stirring plate is rotatably connected to both the left and right ends of the transmission tube, a driven gear is fixedly connected to the top of the stirring plate, and an internal gear ring is fixedly connected to the outer wall of the bottom end of the connecting shell. The internal gear ring and the driven gear are meshed together.

[0010] Furthermore, a second filter element is fixedly connected to the inner wall of the first filter element, and a second stirring plate is fixedly connected to both ends of the transmission rod. The second stirring plate and the first stirring plate are respectively sleeved on the inner walls of the second filter element and the first filter element.

[0011] Furthermore, the disassembly assembly includes a spring fixedly connected to the inner wall of the docking ring, and a retaining post fixedly connected to the other end of the spring.

[0012] Furthermore, each of the left and right ends of the filter element is fixedly connected to a connector, and each connector is fixedly connected to a mating block at its top. A fitting ring is slidably connected to the outer wall of the top of the mating block.

[0013] Furthermore, conveying pipes are fixedly connected to all four sides of the inner wall of the discharge pipe, and floating plates are slidably connected to the bottom of the inner wall of the conveying pipe.

[0014] Furthermore, springs are fixedly connected to both the left and right sides of the inner wall of the conveying pipe, and a closing plate is fixedly connected to the other end of each spring. The opposite end of the closing plate is rotatably connected to the inner wall of the conveying pipe.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the starting drive motor drives the first bevel gear to drive the second bevel gears on both sides to rotate, so that the transmission tube and transmission rod rotate synchronously. The transmission rod drives the second stirring plate to stir inside the second filter element, promoting the mixing of water and impurities and improving filtration efficiency; the transmission tube drives the first stirring plate to revolve, and at the same time achieves rotation with the help of the driven gear and internal gear ring, so as to optimize the water flow between the first and second filter elements, prevent impurities from directly clogging the filter holes, and significantly improve the filtration speed and stability of the two elements.

[0017] 2. In this utility model, when replacing filter element one, the sealed door is opened to expose the filter chamber. Filter element one is lifted upwards, causing the connecting block of the connector to drive the mating ring to squeeze the locking post. The locking post slides along the mating ring to the bottom and is then released. The spring force causes the mating ring to move upwards, and the locking post disengages from the connecting block, completing the disassembly. During installation, the connecting block is inserted into the mating ring, and the locking post is locked under the action of the spring, enabling quick replacement and significantly improving maintenance efficiency and ease of operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-3This utility model provides an embodiment of a chemical water treatment ultrafiltration reverse osmosis device, comprising a filter chamber 1, a sealing door 4 rotatably connected to the front end of the filter chamber 1, a connecting shell 2 fixedly connected to the top end of the filter chamber 1, an input pipe 3 fixedly connected to the left end of the connecting shell 2, a fixing shell 5 fixedly connected to the top end of the connecting shell 2, a drive motor 6 fixedly connected to the inner wall of the fixing shell 5, and a transmission pipe 10 and a transmission rod 9 connected to the drive end of the drive motor 6 via a stirring assembly. The stirring assembly includes a bevel gear 7 fixedly connected to the drive end of the drive motor 6. (Refer to...) Figure 4 Both the top ends of the transmission tube 10 and the transmission rod 9 are fixedly connected to bevel gear 2 8. The bevel gear 1 7 and the bevel gear 2 8 are meshed. Both ends of the transmission tube 10 are rotatably connected to stirring plate 18. The top end of stirring plate 18 is fixedly connected to driven gear 17. The bottom outer wall of the connecting shell 2 is fixedly connected to internal gear ring 16. The internal gear ring 16 and driven gear 17 are meshed. The inner wall of filter element 12 is fixedly connected to filter element 2 15. Both ends of the transmission rod 9 are fixedly connected to stirring plate 2 19. Stirring plate 2 19 and stirring plate 18 are respectively sleeved on the inner walls of filter element 2 15 and filter element 12.

[0028] Specifically: When the external water source to be treated is introduced into the connecting housing 2 through the input pipe 3, the water flows to the filter element 2 15 through the discharge pipe 11. The water pressure flowing through the discharge pipe 11 acts on the delivery pipe 25 at the inlet of the filter element 2 15, causing the closing plate 28 to deflect and open, allowing water to enter the filter element 2 15 for filtration. In order to prevent the backflow of impurities in the primary filtration unit and maintain the system pressure balance, especially in the multi-stage RO pretreatment system, if the flow rate in the filter element 1 12, which represents primary filtration such as microfiltration, is too slow and causes the water level to rise, the float plate 26 floats up and releases the restriction on the closing plate 28. At this time, the elastic force of the second spring 27 immediately pushes the closing plate 28 to reset, tightly closing the outlet of the delivery pipe 25, effectively blocking the reverse permeation of water to the filter element 1 12. To improve filtration efficiency and prevent membrane fouling, the drive motor 6 is activated, driving the bevel gear 7 to rotate the two bevel gears 8 on both sides. This, in turn, causes the connected transmission pipe 10 and transmission rod 9 to rotate in tandem. The rotating transmission rod 9 directly drives the stirring plate 19 to stir within the filter element 15, enhancing the mixing and mass transfer of water and impurities such as colloidal particles, reducing concentration polarization and contaminant accumulation on the membrane surface, and improving the flux and anti-fouling properties of this stage. Simultaneously, the rotating transmission pipe 10 drives the stirring plate 18 on it to revolve, and through the driven gear 17, it rotates with the fixed... The engagement of the internal toothed ring 16 forces the stirring plate 18 to rotate, thereby generating highly turbulent flow in the interstage water region between filter element 12 and filter element 25. This strongly promotes water mixing and uniform distribution, forming continuous shear scouring to prevent suspended solids and colloidal particles from impacting and clogging the micropores of the filter membrane at the outlet of filter element 12 and the inlet of filter element 25. This significantly delays the formation of the filter cake / gel layer and reduces filtration resistance, ultimately greatly improving the filtration speed, flux stability, and extending the cleaning cycle of filter element 12 and filter element 25.

[0029] Reference Figure 5 and Figure 6 Fixed blocks 14 are fixedly connected to the left and right sides of the bottom of the connecting shell 2. A docking ring 21 is fixedly connected to the outer wall of the fixed block 14. A filter element 12 is connected to the inner wall of the docking ring 21 through a disassembly assembly. A discharge pipe 11 is fixedly connected to the bottom of the connecting shell 2 and passes through the top of the filter chamber 1. The disassembly assembly includes a spring 23 fixedly connected to the inner wall of the docking ring 21. A locking post 22 is fixedly connected to the other end of the spring 23. A connector 13 is fixedly connected to both ends of the filter element 12. A docking block 20 is fixedly connected to the top of the connector 13. A fitting ring 24 is slidably connected to the outer wall of the top of the docking block 20. A conveying pipe 25 is fixedly connected to all four sides of the inner wall of the discharge pipe 11. A floating plate 26 is slidably connected to the bottom of the inner wall of the conveying pipe 25. A spring 27 is fixedly connected to the left and right sides of the inner wall of the conveying pipe 25. A closing plate 28 is fixedly connected to the other end of the spring 27. The opposite end of the closing plate 28 is rotatably connected to the inner wall of the conveying pipe 25.

[0030] Specifically: When it is necessary to replace or maintain filter element 12, such as the multi-media pre-filtration unit and filter element 15, which have failed due to membrane fouling, mechanical damage, or performance degradation after long-term operation, the operator first opens the sealing door 4 on the side of the device—this design must meet the sanitary sealing requirements of ASME BPE or GMP standards—to completely expose the sealed cavity of the internal filter chamber 1. When disassembling filter element 12, vertically lifting its main frame will trigger the connector 13 at the bottom, forcing the conical engagement ring 24 integrated in the mating block 20 of the connector 13 to mechanically interfere with the spring-loaded locking post 22 fixed on the support base: the locking post 22 is squeezed during the lifting action and slides along the guide slope of the engagement ring 24. When the locking post 22 passes the bottom edge of the engagement ring 24 and reaches the position of the ring groove below it, the spring 23 is compressed to its maximum. When the operator releases the filter element 12, the locking post 22 immediately retracts radially under the strong rebound of the spring 23. The locking tongue precisely engages with the release groove at the bottom of the engagement ring 24, causing the engagement ring 24 to drive the docking block 20 to move upward as a whole, and finally achieving complete disengagement of the locking post 22 from the docking block 20. This locking structure ensures that disassembly can be completed in a single action without tools, greatly reducing system downtime caused by membrane element replacement and avoiding the risk of disassembly contamination. When installing the new filter element 12, simply align the cleaned mating block 20 vertically with the tapered mating ring 21 on the support base and press it down. The locking bevel on its outer wall will guide the locking post 22 to temporarily expand outward. When the mating block 20 is fully inserted, the locking post 22 automatically returns to the locking groove of the mating block 20 under the constant pressure of the spring 23, forming a three-point circumferential mechanical lock. At the same time, a reliable flange sealing surface is established to ensure zero leakage under 1.0MPa operating conditions. This quick-release system significantly improves the maintenance efficiency of water treatment equipment, and is especially suitable for industrial scenarios that require frequent replacement of pretreatment filter elements or cleaning of reverse osmosis membrane stacks.

[0031] Working principle: When external water enters the connecting shell 2 through the inlet pipe 3, the water flows into the filter element 15 through the outlet pipe 11. As the water flows in the outlet pipe 11, the conveying pipe 25 of the filter element 15 in the outlet pipe 11 is affected by water pressure, causing the closing plate 28 to deflect, thus allowing the water to be discharged. When the water in the filter element 12 is too slow, the water flow rises, causing the float plate 26 to float upwards. This causes the closing plate 28 to close again in the conveying pipe 25 under the elastic force of the spring 27, preventing water from seeping back into the filter element 12. The drive motor 6 is started, causing the bevel gear 7 to drive the two bevel gears 8 on both sides to rotate, thereby causing the transmission pipe 10 and the transmission rod to rotate. The transmission rod 9 rotates, causing the stirring plate 19 to stir inside the filter element 15, thereby allowing water and impurities to flow through the filter element 15 for better filtration. The transmission tube 10 rotates, causing the stirring plate 18 to rotate. The stirring plate 18 rotates under the drive of the driven gear 17 and the internal gear ring 16, causing water to flow between the filter element 12 and the filter element 15, allowing it to pass through the filter element 12 for filtration. This prevents impurities in the flowing water from directly contacting the filter holes between the filter element 12 and the filter element 15, thereby increasing the filtration speed of the filter element 12 and the filter element 15.

[0032] When it is necessary to replace filter element 12 and filter element 15, open the sealing door 4 to expose the inner cavity of filter chamber 1. When filter element 12 is lifted upward, the mating ring 24 connected to the docking block 20 at the connector 13 is squeezed by the locking post 22. The locking post 22 will move along the surface of the mating ring 24. When the locking post 22 moves below the mating ring 24, the filter element 12 is released, and the locking post 22, under the elastic force of the spring 23, causes the mating ring 24 to move upward, allowing the locking post 22 to slide below the mating ring 24 and finally fall off from the docking block 20, thus completing the disassembly of filter element 12. During installation, the docking block 20 is aligned with the docking ring 21, and the locking post 22 is locked on the outside of the docking block 20 under the elastic force of the spring 23, thus completing the installation. This device facilitates the quick replacement of filter element 12.
