Description

Technical Field

[0001] This invention relates to the field of filtration device technology, specifically to a high-efficiency integrated filtration water treatment device for defluorination and silicon removal. Background Technology

[0002] In the field of deep water treatment for defluoridation and desiliconization of groundwater and industrial wastewater, integrated filtration devices often use layered filter cartridges and membranes to achieve multi-stage purification of suspended solids, desiliconization, and defluorination.

[0003] Existing integrated water treatment filtration systems share a single longitudinal flow channel for filtration and backwashing. Normal filtration is a one-way flow from top to bottom, while backwashing relies solely on bottom-inlet reverse flushing, with the drain outlet located at the bottom of the equipment.

[0004] During cleaning, the viscous magnesium silicate flocs trapped in the upper layer must penetrate the entire filter layer from top to bottom before being discharged, resulting in a long travel distance. At the same time, the energy of the unidirectional aeration airflow at the bottom continuously decreases along the height of the filter layer, leading to insufficient cleaning power of the upper filter material and a large amount of sticky dirt residue.

[0005] To address the aforementioned problems, the inventors have proposed a highly efficient integrated fluoride and silica removal filtration water treatment device. Summary of the Invention

[0006] To address the issues of insufficient cleaning power and high levels of sticky residue, the present invention aims to provide a highly efficient integrated filtration water treatment device for defluorination and desilicon removal.

The filter valve has a drain port in the middle, and the drain port is vertically slidably fitted with a movable plate for opening and closing the drain port. The drain port is directly opposite the middle of the filter structure and the opposing water flow area. The filter valve is equipped with an airflow drive mechanism, which is pneumatically connected to a guide mechanism and a movable plate. The exhaust end of the airflow drive mechanism is connected to the middle of the filter structure. Compressed air cuts in from the middle and splits upward and downward. It mixes with the water flow flowing in opposite directions from the top and bottom of the filter valve in the middle of the filter structure to form bubbles.

[0008] The filter valve includes a valve head and a valve housing threaded to the bottom of the valve head, and a sealing ring is provided at the threaded connection between the valve head and the valve housing.

[0009] The filtration structure includes a filter element, a filter membrane, and a filter cylinder. The filter cylinder is installed between the bottom of the valve head and the valve housing. The filter element is installed on the outer wall of the filter cylinder. A gap is provided between the filter cylinder and the filter element, and the gap communicates with the flow chamber.

[0013] Preferably, the bottom of the air cylinder is connected to a connecting frame, the connecting frame is slidably connected to the air cylinder, the connecting frame includes a base frame and a top frame, the base frame and the top frame are interlocked, the interlocking point is limited by a pin, and the movable plate is connected to the outer wall of the base frame.

[0014] Preferably, the guiding mechanism includes a lower pressure plate, a second spring, a flow guide shell, and a base plate; The base plate is fixedly connected inside the valve head of the filter valve. A second spring is provided on the upper surface of the base plate. A lower pressure plate is slidably connected inside the valve head. The lower pressure plate is connected to the top frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the airflow in the middle mixes with the water flow from the top and bottom to generate a large number of cleaning bubbles. The bubbles fill the low-pressure stagnation zone formed by the opposing water flow. With the help of the spiral rod, the water flow from the top and bottom is concentrated and guided to the middle. The guided water flow works in conjunction with the bubbles in the low-pressure stagnation zone, pushing the cleaned material to flow from the top and bottom of the filter valve and quickly converge to the drain port in the middle for discharge.

[0032] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1 - Figure 10 As shown, the present invention provides a high-efficiency integrated fluoride and silicon removal filtration water treatment device, including a filter valve 1 and an inlet 11 and an outlet 12 disposed on both sides of the top of the filter valve 1. The filter valve 1 has a layered filtration structure inside, and the inner cavity of the filter valve 1 is divided into a central cavity 14 and a flow cavity 15. The central cavity 14 and the flow cavity 15, together with the layered filtration structure, form a U-shaped unidirectional flow channel. The top of the filter valve 1 is equipped with a guide mechanism 7, which is used to switch the water flow path between the central chamber 14 and the flow chamber 15. The filter valve 1 has a drain port 13 in the middle. The drain port 13 is vertically slidably fitted with a movable plate 9 for opening and closing the drain port 13. The drain port 13 is directly opposite the middle of the filter structure and the opposing water flow area. The filter valve 1 is equipped with an airflow drive mechanism 2, and the airflow drive mechanism 2 is pneumatically connected to a guide mechanism 7 and a movable plate 9. The exhaust end of the airflow drive mechanism 2 is connected to the middle of the filter structure. Compressed air cuts in from the middle and splits upward and downward. It mixes with the water flow that flows towards the top and bottom of the filter valve 1 in the middle of the filter structure to form bubbles.

[0034] The filter valve 1 includes a valve head and a valve body threaded to the bottom of the valve head, and a sealing ring 8 is provided at the threaded connection between the valve head and the valve body; The purpose of this design is to allow filter valve 1 to be installed and disassembled separately. During installation, a sealing ring 8 is provided to seal the connection.

[0035] The filtration structure includes a filter element 3, a filter membrane 4, and a filter cylinder 5. The filter cylinder 5 is installed between the bottom of the valve head and the valve housing. The filter element 3 is installed on the outer wall of the filter cylinder 5. A gap is provided between the filter cylinder 5 and the filter element 3. This gap communicates with the flow chamber 15. The central cavity 14 extends from the top of the filter cylinder 5 to the bottom outside of the filter cylinder 5. The bottom center port of the filter cartridge 5 is provided with an inner ring, and several filter membranes 4 are stacked sequentially on the upper surface of the inner ring; The purpose of this design is to allow water to enter through the inlet 11 during the filtration process, then flow through the flow chamber 15 into the gap, pass through the filter element 3 and the filter membrane 4, undergo secondary filtration, and then flow along the central chamber 14 towards the outlet 12, thereby achieving the filtration effect on the water flow.

[0036] The filter cartridge 5 includes an upper cartridge 52 and a lower cartridge 51 threaded to the bottom of the upper cartridge 52. The filter element 3 has several filter holes on the side near the gap, and the bottom of the lower cartridge 51 has several fine holes 510. The bottom of the filter cartridge 5 extends into a bottom tube, and several flow ports 10 are provided on the outer wall of the bottom tube. The purpose of this design is that the incoming water flows through the gaps to the filter element 3 for filtration, passes through several fine holes 510 to the filter membrane 4 for filtration, and the water at the bottom of the filter valve 1 is supplemented and pressurized through the flow port 10. After being filtered by the filter membrane 4, it is discharged through the outlet 12.

[0037] The airflow drive mechanism 2 includes a ring body 21 and an impeller 22. The impeller 22 is rotatably connected inside the ring body 21. An air inlet 210 is connected to the outer wall of the ring body 21. A rotating shaft is connected to the middle of the ring body 21. The rotating shaft extends to the top of the filter cartridge 5. Two spiral rods 6 are symmetrically connected to the outer wall of the rotating shaft. The two spiral rods 6 are respectively located at the top of the upper cylinder 52 and the bottom of the lower cylinder 51. The purpose of this setup is to allow compressed gas to be introduced into the air inlet 210 during cleaning and sewage discharge, causing the impeller 22 to rotate. This rotation drives the two spiral rods 6 to rotate, pushing the water flow from the top of the upper cylinder 52 downwards and the water flow from the bottom of the lower cylinder 51 upwards, thus rinsing the stacked filter membranes 4. Figure 5 and Figure 9 As shown, the rinsing water flows through several fine holes 510 in the middle of the lower cylinder 51, is discharged into the gap, passes through the middle of the filter element 3, and is discharged to the drain port 13. This achieves the water flow converging from the top and bottom in the filter structure. During the convergence process, the filter membrane 4 and filter element 3 are rinsed, and finally discharged from the drain port 13 in the middle, shortening the sewage discharge path and improving the sewage discharge efficiency.

[0038] The airflow drive mechanism 2 also includes an air cylinder 24. The top of the air cylinder 24 is connected to a connecting pipe 23, and the bottom end of the connecting pipe 23 is connected to the ring body 21. An air guide cylinder 26 is slidably connected to the inner wall of the air cylinder 24. An opening is provided on the outer wall of the air guide cylinder 26. An extension pipe 27 is connected between the air cylinder 24 and the filter valve 1. A first spring 28 is provided between the air guide cylinder 26 and the air cylinder 24. The first spring 28 is made of corrosion-resistant material to prevent water flow from corroding it. The purpose of this setup is to combine Figure 2 - Figure 3 As shown, the airflow inside the ring 21 is transported through the impeller 22 and the connecting pipe 23. The airflow pushes the air guide cylinder 26 to slide downward along the inner wall of the air cylinder 24 and squeezes the first spring 28. Then the port is connected to the extension pipe 27, and then the compressed gas is injected into the interior of the filter valve 1, where it mixes with the water flow that converges in the middle, top and bottom of the filter element 3 to form bubbles. The air-water mixture generates bubbles that burst in the gaps between the filter membrane 4 and the filter element 3, releasing micro-shock waves. Countless bubbles stir the water, creating strong turbulence. The tightly packed silico-fluorine sludge is broken up into fine suspended solids, making it difficult for it to settle and accumulate in dead corners.

[0039] The air bubbles in the middle are split upwards and downwards, respectively flushing the upper interception layer and the lower defluorination layer, while forming an air curtain barrier to prevent the upper silica flocs from settling and contaminating the lower defluorination filter material, thus avoiding filter material failure.

[0040] The water flow at the top and bottom counteracts the water pressure in the middle of the filter element 3, creating a low-pressure stagnation zone. Air bubbles fill this zone, pushing the dispersed dirt quickly towards the middle drain outlet 13, preventing dirt from sticking back to the filter media.

[0041] The bubbles themselves have a disturbance capability, resulting in uniform cleaning force between the upper and lower filter layers.

[0042] The bottom of the air cylinder 26 is connected to a connecting frame 25, which is slidably connected to the air cylinder 24. The connecting frame 25 includes a base frame 251 and a top frame 252. The base frame 251 and the top frame 252 are inserted into each other, and a pin 253 is used to limit the insertion. The movable plate 9 is connected to the outer wall of the base frame 251. The purpose of this design is to allow the pin 253 to be removed when disassembling the valve head and valve body of filter valve 1, so that the base frame 251 and top frame 252 can be disassembled automatically, facilitating subsequent maintenance of filter valve 1.

[0043] Combination Figure 5 - Figure 8 As shown, the guide mechanism 7 includes a lower pressure plate 71, a second spring 72, a flow guide shell 73, and a base plate 74; The substrate 74 is fixedly connected to the inside of the valve head of the filter valve 1. A second spring 72 is provided on the upper surface of the substrate 74. A lower pressure plate 71 is slidably connected inside the valve head. The lower pressure plate 71 is connected to the top frame 252. The bottom of the lower pressure plate 71 is slidably connected to the substrate 74. The bottom of the lower pressure plate 71 is connected to the flow guide shell 73. The purpose of this arrangement is that when the top frame 252 moves vertically downward, it drives the lower pressure plate 71 to move downward, squeezing the second spring 72, and the guide shell 73 moves vertically downward.

[0044] A long opening is provided on the top of one side of the flow guide shell 73, with the long opening near the end of the inlet 11. A round hole is provided on one side of the flow guide shell 73, with the round hole near the end of the outlet 12. The purpose of this setup is to combine Figure 6 and Figure 8 As shown, in the filtration state, the round hole is connected to one end of the outlet 12, and the guide shell 73 isolates one end of the inlet 11. After filtration, the water flows out from the outlet 12. In the cleaning state, the elongated opening is connected to the inlet 11, and the guide shell 73 isolates the outlet 12 to guide the water flow.

[0045] Several rubber soft balls 512 are respectively arranged on the inner walls of the lower cylinder 51 and the upper cylinder 52. The spiral rod 6 and the rubber soft balls 512 cooperate with each other. The spiral rod 6 and the rubber soft balls 512 are made of fumed silica gel, which has been treated by de-volatilization and boiling water, so that no free additives are released, thus preventing pollution to the passing water flow. The purpose of this arrangement is to allow the spiral rod 6 to contact and vibrate with several rubber soft balls 512 during rotation. In the specific arrangement, the rubber soft balls 512 can be embedded, with a portion exposed on the inner wall of the lower cylinder 51 and the upper cylinder 52. During the high-frequency vibration, the vibration is transmitted to the lower cylinder 51 and the upper cylinder 52, which, together with the air bubbles, improves the cleaning effect of the filter membrane 4 and the filter element 3. Simultaneously, the injected airflow is pressurized, and the water flows upward and downward and is discharged from the drain outlet 13 in the middle. There is discharge pressure, which draws away the internal cleaning materials and further improves the discharge efficiency.

[0046] Working principle: External raw water enters the valve head through the inlet 11 at the top of the filter valve 1. The guide shell 73 inside the guide mechanism 7 is kept in the upper position under the support of the second spring 72. The round hole of the guide shell 73 is connected to the outlet 12, and the long opening closes the water inlet channel. Water flows through the flow chamber 15 into the gap between the filter cylinder 5 and the filter element 3. First, it passes through the filter holes on the side wall of the filter element 3 to intercept suspended solids. The water continues to flow downward and reaches the bottom inner ring of the filter cylinder 5 through the fine hole 510 at the bottom of the lower cylinder 51. The multi-layer stacked filter membrane 4 completes the desiliconization and defluorination deep filtration. The filtered clean water flows into the central cavity 14, flows upward along the central cavity 14 back to the inside of the valve head, and is then transported outward from the outlet 12 through the round hole of the guide shell 73. During this stage, the airflow drive mechanism 2 has no air source input, the impeller 22 and the screw rod 6 remain stationary, and the rubber soft ball 512 on the cylinder wall only plays a role in buffering and stabilizing the flow, weakening the impact of high-speed water flow, avoiding disturbance to the stratified filter membrane 4, ensuring stable stratified filtration, and the movable plate 9 blocks the middle sewage outlet 13, preventing sewage leakage.

[0047] Compressed air is introduced into the ring body 21 through the air inlet 210. One airflow drives the impeller 22 to rotate, and the other airflow is sent into the air cylinder 24 through the connecting pipe 23. The air pressure pushes the air guide cylinder 26 to slide downward and squeeze the first spring 28. The opening on the outer wall of the air guide cylinder 26 is connected to the extension pipe 27. Compressed air is sent into the middle of the filter structure through the extension pipe 27. As the air guide tube 26 moves downward, it simultaneously drives the bottom connecting frame 25 to move downward as a whole. On one hand, the base frame 251 drives the movable plate 9 to slide downward, opening the middle drain outlet 13. On the other hand, the top frame 252 presses down the lower pressure plate 71 of the guide mechanism 7. The lower pressure plate 71 overcomes the elastic force of the second spring 72 and drives the guide shell 73 to move downward. The long opening of the guide shell 73 aligns with the water inlet 11 and the round hole seals the water outlet 12, cutting off the water production channel and switching to the cleaning water path.

[0048] Clean water is introduced into the inlet 11, and the water flow is divided into two paths: one path enters the upper part of the filter cylinder 5 along the flow chamber 15, forming a top cleaning water flow from top to bottom; the other path enters the bottom of the filter cylinder 5 through the bottom pipe flow port 10, forming a bottom cleaning water flow from bottom to top. The two water flows collide with each other in the middle of the filter cylinder 5. Compressed air supplied through extension pipe 27 cuts into the middle of the filter structure, and the airflow is split into two directions, upward and downward, and fully mixed with the two-way countercurrent water flow to generate a large number of micron-sized cleaning bubbles. The bursting of the bubbles generates cavitation impact, which peels off the viscous silicone colloid in the micropores of filter element 3 and filter membrane 4. The gas and liquid phases form strong turbulence, which breaks up the clumps of sludge. The airflow in the middle forms an air curtain barrier, separating the dirt in the upper and lower filter layers and preventing cross-layer pollution.

[0049] The airflow inside the ring 21 continuously drives the impeller 22 to rotate, and the rotating shaft drives the upper and lower spiral rods 6 to rotate synchronously. During the rotation of the spiral rods 6, they continuously and elastically impact the rubber soft balls 512 on the inner wall of the upper cylinder 52 and the lower cylinder 51, generating high-frequency micro-vibrations, which shake off the sludge attached to the cylinder wall and the surface of the filter element. The rotating screw 6 synchronously agitates the water inside the cylinder. The bottom spiral blades push the bottom water upwards, and the upper spiral blades push the upper water downwards, enhancing the bidirectional confluence and flushing effect. During the flushing process, pressure is generated, which helps to quickly discharge the cleaned material out of the nearby open drain outlet 13.

The specific mechanical connection methods for each part can also employ conventional methods such as bolts, rivets, and welding, which are already well-established in the prior art and will not be elaborated upon here.
