Abstract
Description
Technical Field
[0001] This utility model belongs to the field of direct drinking water treatment technology, specifically a direct drinking water treatment device based on ceramic membrane filtration. Background Technology
[0002] Direct drinking water treatment is a process that uses physical filtration and deep purification to purify raw water such as municipal tap water and rural well water into water that meets the "direct drinking" requirements of the "Standards for Drinking Water Quality". Currently, most mainstream direct drinking water treatment devices adopt the technical approach of "pretreatment + core membrane filtration + deep purification". Among them, ceramic membranes are widely used in small and medium-sized household and commercial direct drinking water devices due to their advantages such as resistance to pollution, long life and ability to retain minerals.
[0003] Existing direct drinking water treatment devices based on ceramic membranes generally adopt a static ceramic membrane filtration structure in the core filtration stage. Impurities in the raw water tend to accumulate on the surface of the ceramic membrane. At the same time, the flow path of the raw water remains unchanged, and the impurities cannot detach from the membrane surface on their own, affecting the filtration efficiency of the ceramic membrane. Consequently, the ceramic membrane needs to be rinsed frequently. Therefore, this utility model provides a direct drinking water treatment device based on ceramic membrane filtration. Utility Model Content
[0004] To overcome the shortcomings of existing technologies and solve the problem of impurities accumulating on the surface of ceramic membranes, this utility model proposes a direct drinking water treatment device based on ceramic membrane filtration.

[0006] The rotating mechanism includes a motor, a gear, an external gear ring, and a first fixed plate. An external block is fixedly installed on the outer end of the upper half of the ceramic membrane filter tank. A motor is fixedly installed on the upper end of the external block. The output end of the motor passes through the surface of the external block and is connected to the gear. The gear meshes with the external gear ring on the inner end. The external gear ring is fixedly installed on the outer surface of the first fixed plate.
[0007] A second fixing plate is installed at the lower end of the first fixing plate, a third fixing plate is installed at the lower end of the second fixing plate, and a fourth fixing plate is installed at the lower end of the third fixing plate. A fixing post is fixedly installed on the outer side of the lower surface of the first fixing plate, and the lower end of the fixing post passes through the surfaces of the second and third fixing plates and is fixedly connected to the fourth fixing plate.
[0008] Limiting rings are provided at the connection points of the No. 1, No. 2, No. 3 and No. 4 fixing plates with the ceramic membrane filter tank, and the limiting rings are fixedly installed on the inner wall surface of the ceramic membrane filter tank.
[0009] A water-blocking ring plate is fixedly installed on the upper surface of the first fixed plate. A plurality of conical grooves are evenly arranged on the upper surface of the first fixed plate corresponding to the inner end of the water-blocking ring plate. A fixing pipe is fixedly installed at the lower end of the conical groove.
[0010] Multiple drainage holes are evenly arranged on the surface of the fixed tube, and an inner protrusion is provided at the lower end of the drainage hole. A ceramic membrane is installed inside the fixed tube.
[0011] The collection mechanism includes a collection chamber and a drain pipe. Multiple collection chambers are fixedly installed on the outer surface of the ceramic membrane filter tank. Circular grooves are set on the surface of the ceramic membrane filter tank corresponding to the positions of the collection chambers. Drain pipes are fixedly installed on the outer side of the collection chambers, and the positions of the multiple drain pipes are staggered.
[0012] The ceramic membrane filter tank is provided with a lid at the top. Multiple bolts are evenly arranged on the outer side of the lid. The lid is connected to the upper surface of the ceramic membrane filter tank by the bolts. A sealing gasket is provided at the connection between the lower end of the lid and the ceramic membrane filter tank and the water baffle plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The direct drinking water treatment device based on ceramic membrane filtration described in this utility model controls the rotation of the first fixed plate through a rotating mechanism. The fixed column drives the first to fourth fixed plates to be rigidly connected. At the same time, the fixed pipe is fixed between the fixed plates. When the rotating mechanism is started, the fixed pipe and the ceramic membrane rotate synchronously, changing the single water flow path. When the raw water comes into contact with the ceramic membrane through the conical groove, the centrifugal force generated by the rotation throws impurities toward the inner wall of the fixed pipe, and then discharges them into the collection chamber through the drain hole of the fixed pipe. This realizes that impurities are separated before they come into contact with the micropores of the ceramic membrane, avoiding the accumulation of impurities on the membrane surface, thereby reducing the number of times the ceramic membrane is frequently rinsed.
[0015] 2. The direct drinking water treatment device based on ceramic membrane filtration described in this utility model ensures that impurities are quickly discharged without backflow through multiple collection chambers and staggered drain pipes, reducing the risk of contact between impurities and the ceramic membrane; the limiting ring radially limits the rotating parts, and the inner protrusion at the lower end of the drain hole fixes the position of the ceramic membrane to prevent the membrane from shifting during rotation and causing uneven filtration; at the same time, the tank lid sealing gasket and water supply pipe are sealed to prevent water leakage and external pollution.

After filtration inside ceramic membrane filter tank 4, it is led out to activated carbon filter tank 6 through secondary water pipe 5 at the lower center of ceramic membrane filter tank 4. The clean water entering activated carbon filter tank 6 through secondary water pipe 5 comes into contact with columnar activated carbon in the tank.

The gear 10 drives the external gear ring 11 to rotate through meshing. The external gear ring 11 is fixed on the outer surface of the first fixed disk 12, so the first fixed disk 12 rotates synchronously with the external gear ring 11.

The limiting rings 22 are fixed to the inner wall of the ceramic membrane filter tank 4 to radially limit the rotating components such as the first fixed plate 12 and the second fixed plate 13, so as to prevent them from shifting during rotation and provide support.
[0037] A lid 24 is provided at the upper end of the ceramic membrane filter tank 4. Multiple bolts 25 are evenly arranged on the outer side of the lid 24. The lid 24 is connected to the upper surface of the ceramic membrane filter tank 4 by the bolts 25. A sealing gasket is provided at the connection between the lower end of the lid 24 and the ceramic membrane filter tank 4 and the water baffle plate 16 to prevent water from leaking out from the water baffle plate 16.
[0038] A water-blocking ring plate 16 is fixedly installed on the upper surface of the first fixed plate 12. A plurality of conical grooves 17 are evenly arranged on the upper surface of the first fixed plate 12 corresponding to the inner end of the water-blocking ring plate 16. A fixed pipe 19 is fixedly installed at the lower end of the conical groove 17. The water-blocking ring plate 16 restricts the raw water within a certain range.

[0040] The collection mechanism includes a collection chamber 23 and a drain pipe 26. Multiple collection chambers 23 are fixedly installed on the outer surface of the ceramic membrane filter tank 4. Circular grooves are set on the surface of the ceramic membrane filter tank 4 corresponding to the positions of the collection chambers 23. Drain pipes 26 are fixedly installed on the outer side of the collection chambers 23. The positions of the multiple drain pipes 26 are staggered. A collection chamber 23 is set between every two corresponding fixed discs. The collection chamber 23 collects the impurity water discharged between the corresponding two fixed discs separately. A drain pipe 26 is set on the outer side of each collection chamber 23. The drain pipe 26 discharges the impurity water inside the collection chamber 23 for corresponding treatment.
[0041] A lid 24 is provided at the upper end of the ceramic membrane filter tank 4. Multiple bolts 25 are evenly arranged on the outer side of the lid 24. The lid 24 is connected to the upper surface of the ceramic membrane filter tank 4 by the bolts 25. A sealing gasket is provided at the connection between the lower end of the lid 24 and the ceramic membrane filter tank 4 and the water baffle plate 16. The lid 24 is provided at the upper end of the ceramic membrane filter tank 4. Multiple bolts 25 are evenly arranged on the outer side of the lid 24. The lid 24 is fixed to the upper end of the ceramic membrane filter tank 4 by the bolts 25. A sealing gasket is provided at the connection between the lower end of the lid 24 and the ceramic membrane filter tank 4 and the water baffle plate 16 to prevent water from leaking out from the water baffle plate 16.
[0042] Working principle: Support plate 1 provides stable support. Raw water tank 2 temporarily stores the raw water to be treated. Activated carbon filter tank 6 is filled with columnar granular activated carbon. After the raw water passes through ceramic membrane filter tank 4, it undergoes deep filtration. The top cover 24 of ceramic membrane filter tank 4 is sealed to the tank body by bolts 25. The connection between the lower end of the cover 24 and the ceramic membrane filter tank 4 and the water baffle plate 16 is sealed with a gasket to prevent leakage. Limiting ring 22 is fixed to the inner wall of ceramic membrane filter tank 4, radially limiting rotating components such as the first fixing plate 12 and the second fixing plate 13, preventing displacement during rotation while providing support. When water pump 7 is started, the raw water to be treated in raw water tank 2 is pressurized by water pump 7 and flows through... The water is transported through the primary water supply pipe 3 to the ceramic membrane filter tank 4. The connection between the primary water supply pipe 3 and the ceramic membrane filter tank 4 is sealed to prevent raw water leakage. After entering the ceramic membrane filter tank 4, the raw water flows downward into the space above the first fixed plate 12. The water baffle plate 16 is fixed to the upper surface of the first fixed plate 12 and can rotate synchronously with the first fixed plate 12. The water baffle plate 16 restricts the water flow inside, reducing the range of raw water movement. The raw water flows evenly into the area of the fixed pipe 19 below through the guiding action of the conical groove 17. The motor 9 is started, and the output shaft of the motor 9 drives the gear 10 to rotate. The gear 10 drives the external gear ring 11 to rotate through meshing. The external gear ring 11 is fixed to the outer surface of the first fixed plate 12, so the first fixed plate 12... The fixed plate 12 rotates synchronously with the external gear ring 11. The first fixed plate 12 is rigidly connected to the second fixed plate 13, the third fixed plate 14, and the fourth fixed plate 15 through the fixed column 18. Therefore, when the first fixed plate 12 rotates, it drives the second fixed plate 13, the third fixed plate 14, the fourth fixed plate 15, and all the fixed pipes 19 and ceramic membranes 21 to rotate synchronously through the fixed column 18. The raw water flowing in through the conical groove 17 comes into contact with the ceramic membrane 21 inside the fixed pipe 19. When the fixed pipe 19 rotates, the raw water rotating with the fixed pipe 19 is thrown towards the inner wall of the fixed pipe 19 under the action of centrifugal force. At the same time, drainage holes 20 are evenly arranged on the surface of the fixed pipe 19. Impurities thrown to the inner wall of the fixed pipe 19 are discharged through the drainage holes. The water 20 is thrown out of the interior of the fixed tube 19 and enters the inner chamber corresponding to the ceramic membrane filter tank 4; the lower end of the drain hole 20 is provided with an inner protrusion to axially position the ceramic membrane 21 and prevent the ceramic membrane 21 from sliding down during rotation. The impurity water thrown out through the drain hole 20 of the fixed tube 19 enters the inner chamber corresponding to the ceramic membrane filter tank 4. Under the guidance of gravity and centrifugal force of rotation, it enters the collection chamber 23 corresponding to the side end of the ceramic membrane filter tank 4. The collection chamber 23 is connected to the ceramic membrane filter tank 4. The impurity water enters the collection chamber 23 and is discharged through the drain pipe 26 connected to the outside of the collection chamber 23. The drain pipes 26 are staggered and multiple sets are provided on the fixed plate to avoid interference between the pipes when multiple sets of collection chambers 23 drain.Multiple collection chambers 23 are provided, with one collection chamber 23 located outside every two corresponding fixed plates. The raw water is treated individually based on its quality. Clean water permeating into the hollow inner cavity of the ceramic membrane 21 flows downwards along the inner cavity and exits from the lower end of the ceramic membrane 21. It converges at the lowest region of the ceramic membrane filter tank 4 and is then led to the activated carbon filter tank 6 via a secondary water supply pipe 5 at the center of the lower end of the ceramic membrane filter tank 4. The clean water entering the activated carbon filter tank 6 through the secondary water supply pipe 5 comes into contact with the columnar activated carbon inside the tank. The activated carbon adsorbs residual chlorine, odor substances, and some organic pollutants in the clean water, further improving the taste. The water is then connected to an external pipeline via an external connecting pipe for the next step of the process.
