A direct drinking water soluble organic matter adsorption interception treatment system

Abstract

This invention discloses a direct drinking water dissolved organic matter adsorption and interception treatment system, relating to the field of activated carbon filtration technology. The invention includes a direct drinking water organic matter adsorption and interception faucet, with an adsorption and interception mechanism at one end. A treated water outlet is located at the center of the bottom of the adsorption and interception mechanism. An installation mechanism is located at the top of the faucet, away from the adsorption and interception mechanism. The advantages are: in the pressure blocking mechanism, three pressure abutment blocks sense the water pressure inside the adsorption and interception mechanism in real time. When the activated carbon filter element experiences poor water flow and abnormally high internal pressure due to dissolved organic matter clogging the activated carbon molecular grid, the connecting rod pushes the blocking plate to move, automatically cutting off the inlet water path. This prevents excessive pressure from damaging the adsorption and interception mechanism and the direct drinking water organic matter adsorption and interception faucet, while simultaneously prompting the user to replace the filter element in time, ensuring the safe operation of the system.

Description

Technical Field

[0001] This invention relates to the field of activated carbon filtration technology, and more particularly to a system for adsorbing and retaining dissolved organic matter in drinking water. Background Technology

[0002] Currently, with the increasing demands of people for drinking water quality, household and commercial direct drinking water treatment devices have been widely used. Common direct drinking water purification devices or water purification equipment usually use activated carbon filter cartridges to adsorb residual chlorine, off-colors and odors, and dissolved organic matter in the water.

[0003] Dissolved organic matter includes small molecule DOM and large molecule DOM. Small molecule DOM can enter the micropores of activated carbon and be effectively adsorbed without clogging. Instead, it occupies adsorption sites until the activated carbon is saturated. Large molecule DOM cannot enter the micropores and will be adsorbed on the pore walls of mesopores or macropores or directly cover the outer surface of activated carbon particles. When used in a direct drinking water purification device, over time, the occupation of adsorption sites by small molecule DOM and the covering effect of large molecule DOM can lead to clogging, resulting in more water entering than leaving the device, increased internal pressure, and damage to the purification device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a direct drinking water dissolved organic matter adsorption and retention treatment system, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A direct drinking water dissolved organic matter adsorption and interception treatment system includes a direct drinking water organic matter adsorption and interception faucet. One end of the faucet is equipped with an adsorption and interception mechanism. A treated water outlet is located at the center of the bottom of the adsorption and interception mechanism. An installation mechanism is located at the top of the faucet, away from the adsorption and interception mechanism. A pressure blocking mechanism is located at the top of the faucet, between the installation mechanism and the adsorption and interception mechanism. A raw water outlet is located at the bottom of the faucet, away from the adsorption and interception mechanism. A ball valve mechanism is installed through the bottom of the faucet, away from the adsorption and interception mechanism. A sealing mechanism is located at the bottom of the installation mechanism. A ball valve groove is installed through the faucet, away from the adsorption and interception mechanism, and the ball valve mechanism is located within the ball valve groove.

[0006] Furthermore, the direct drinking water organic matter adsorption and interception faucet is connected to the adsorption and interception mechanism through a ball valve groove, and the installation mechanism is connected to the ball valve groove inside the direct drinking water organic matter adsorption and interception faucet through a sealing mechanism.

[0007] Furthermore, the installation mechanism includes a clamp sleeve, the top of which is provided with nut clamps evenly distributed around the central axis of the clamp sleeve, one side of the outer wall of each nut clamp is provided with a tightening external thread, the top of each nut clamp is provided with a limiting block, one side of the inner wall of each nut clamp is provided with an inner protrusion evenly distributed from top to bottom, the outer wall of the nut clamp is provided with a tightening nut, and the inner wall of the tightening nut is provided with a tightening internal thread.

[0008] Furthermore, the external threads on the outer walls of the multiple nut clamps form a complete tightening thread, and the tightening nut is threadedly connected to the complete tightening thread formed by the internal threads and the multiple external threads, so that the nut clamp is threadedly fitted onto the outer walls of the multiple nut clamps.

[0009] Furthermore, the ball valve mechanism includes a rotating part, and a ball valve body is provided at one end of the rotating part near the organic matter adsorption and interception faucet of the direct drinking water. A raw water passage is horizontally penetrated through the ball valve body, and the raw water passage and the rotating part are parallel to each other. A purified water passage is vertically penetrated through the ball valve body, and the purified water passage and the rotating part are perpendicular to each other. The purified water passage is not connected to the raw water passage, and the purified water passage enters from the top of the ball valve body and exits from the side of the ball valve body away from the rotating part. The ball valve body, the raw water passage, and the purified water passage are all located in the ball valve groove.

[0010] Furthermore, the adsorption interception mechanism includes an adsorption interception chamber, the top of which is provided with a detachable outer cover, the top of the inner wall of the adsorption interception chamber is provided with a surrounding adsorption interception internal thread, the bottom of the outer wall of the detachable outer cover is provided with a surrounding adsorption interception external thread, and the adsorption interception chamber is connected to the detachable outer cover through the threaded connection of the adsorption interception internal thread and the adsorption interception external thread. The bottom of the adsorption interception chamber is provided with an annular filter element mounting ring, the top of which is provided with an activated carbon filter element, the bottom of the outer wall of the activated carbon filter element is provided with a filter element external thread, and the inner wall of the filter element mounting ring is provided with a mounting ring internal thread. The activated carbon filter element is threadedly connected to the filter element mounting ring through the cooperation of the filter element external thread and the mounting ring internal thread.

[0011] Furthermore, the activated carbon filter element also includes an activated carbon filter element shell, inside which are uniformly stacked activated carbon layers, and between each of the activated carbon layers are filter element flat membranes, and between the ends of the activated carbon filter element shell closest to the filter element mounting ring are water outlet layers.

[0012] Furthermore, the pressure blocking mechanism includes a pressure blocking housing, with three pressure grooves running through it. A blocking plate groove runs through the end of the pressure blocking housing near the installation mechanism, and the pressure grooves and the blocking plate grooves are interconnected. Each pressure groove is provided with a connecting rod, and each connecting rod is provided with a pressure abutment block at the end near the adsorption and interception mechanism. A blocking plate is provided in the blocking plate groove, and the connecting rod extends towards the installation mechanism and connects to the blocking plate.

[0013] Furthermore, the sealing mechanism includes a rubber base pad, which is annular in shape. The top of the rubber base pad has evenly distributed clearance grooves, and the inner wall of the rubber base pad has evenly distributed eight-part ring plates. Each of the eight-part ring plates has a rotating abutment claw that is rotatably connected to it. The outer side of the top of each abutment claw has an outwardly expanding end, and the same side of the abutment claw away from the outwardly expanding end has an abutment compression end. The outer wall of the top of the abutment claw has a surrounding rubber sealing ring, which is annular in shape. One side of the inner wall of the rubber sealing ring has an annular recessed groove, and the outwardly expanding ends are all located in the recessed groove and are engaged.

[0014] Compared with existing technologies, the advantages of this invention are: 1. In the pressure blocking mechanism, three pressure contact blocks sense the water pressure inside the adsorption and interception mechanism in real time. When the activated carbon filter cartridge is clogged by dissolved organic matter, resulting in poor water flow and abnormally high internal pressure, the connecting rod pushes the blocking plate to move, automatically cutting off the water inlet path. This prevents excessive pressure from damaging the adsorption and interception mechanism and the direct drinking water organic matter adsorption and interception faucet. At the same time, it reminds the user to replace the filter cartridge in time to ensure the safe operation of the system.

[0015] 2: In the adsorption and interception mechanism, multiple layers of activated carbon are evenly stacked inside the activated carbon filter element, which can efficiently adsorb residual chlorine, organic matter, and odors. A filter element flat plate membrane is set between adjacent activated carbon layers, which can not only prevent the loss of activated carbon particles, but also further intercept tiny impurities. The effluent layer collects clean water. The multi-layer composite structure significantly improves the removal effect of dissolved organic matter and ensures the quality of drinking water.

[0016] 3. The installation mechanism adopts a split-type nut clamp with a threaded fit to the tightening nut. When tightened, the nut clamp contracts radially, firmly gripping the water inlet pipe through the inner protrusion. The limit block prevents over-tightening. It can quickly and easily seal and fix the water supply pipe without special tools. It has high installation efficiency and good adaptability. The sealing mechanism uses the lever principle. The axial pressure acts on the abutting and squeezing end, causing the abutting rotating claw to rotate. The outward expansion end pushes the rubber sealing ring outward, making it radially close to the inner wall of the shell. Therefore, the greater the water pressure or tightening force, the tighter the seal. After the pressure is released, the rubber elasticity can help to reset, effectively avoiding pressure and water leakage problems during long-term use, and maintaining the pressure range within the direct drinking water dissolved organic matter adsorption and interception treatment system, which can better activate the pressure blocking mechanism.

[0019] Example 1 Reference Figures 1-13 A direct drinking water dissolved organic matter adsorption and interception treatment system includes a direct drinking water organic matter adsorption and interception faucet 1, an adsorption and interception mechanism 5 at one end of the faucet 1, a treated water outlet 6 at the center of the bottom of the adsorption and interception mechanism 5, an installation mechanism 3 at the top of the faucet 1 away from the adsorption and interception mechanism 5, a pressure blocking mechanism 7 at the top of the faucet 1 between the installation mechanism 3 and the adsorption and interception mechanism 5, and a bottom of the faucet 1 away from the adsorption and interception mechanism. One end of the bottom of the device 5 is provided with a raw water outlet 2. The end of the direct drinking water organic matter adsorption and interception faucet 1 away from the adsorption and interception mechanism 5 is provided with a ball valve mechanism 4. The bottom of the installation mechanism 3 is provided with a sealing mechanism 8. The end of the direct drinking water organic matter adsorption and interception faucet 1 away from the adsorption and interception mechanism 5 is provided with a ball valve groove 9, and the ball valve mechanism 4 is located in the ball valve groove 9. The direct drinking water organic matter adsorption and interception faucet 1 is connected to the adsorption and interception mechanism 5 through the ball valve groove 9. The installation mechanism 3 is connected to the ball valve groove 9 in the direct drinking water organic matter adsorption and interception faucet 1 through the sealing mechanism 8.

[0020] The top of the direct drinking water organic matter adsorption and interception faucet 1, away from the adsorption and interception mechanism 5, is equipped with an installation mechanism 3 for connecting the direct drinking water organic matter adsorption and interception faucet 1 to the water supply pipeline. A sealing mechanism 8 is installed at the bottom of the installation mechanism 3 to ensure the sealing of the connection. At the top of the direct drinking water organic matter adsorption and interception faucet 1, between the installation mechanism 3 and the adsorption and interception mechanism 5, a pressure blocking mechanism 7 is configured. Its function is to automatically block the water path and remind the user to replace it in time when the water filtration effect is poor due to water-soluble organic impurities clogging the activated carbon molecular grid inside the adsorption and interception mechanism 5, and the pressure is too high due to the water output being less than the inlet water.

[0021] The bottom of the direct drinking water organic matter adsorption and interception faucet 1, away from the adsorption and interception mechanism 5, is provided with a raw water outlet 2, which can separately release daily water that has not undergone deep adsorption treatment. The end of the direct drinking water organic matter adsorption and interception faucet 1 away from the adsorption and interception mechanism 5 is provided with a ball valve mechanism 4 through it horizontally. At the same time, a matching ball valve groove 9 is opened in the corresponding position inside the faucet. The ball valve mechanism 4 is installed in the ball valve groove 9, and the water path can be switched by rotating the ball valve.

[0022] The installation mechanism 3 is connected to the ball valve groove 9 inside the direct drinking water organic matter adsorption and interception faucet 1 through the sealing mechanism 8. The ball valve groove 9 is then connected to the flow channel inside the adsorption and interception mechanism 5. After the raw water enters from the installation mechanism 3, it passes through the sealing mechanism 8 and reaches the ball valve groove 9. The flow direction is controlled by the ball valve mechanism 4. One is to directly guide it to the raw water outlet 2, providing raw water that has not been adsorbed and treated. The other is to guide it to the adsorption and interception mechanism 5. After adsorbing and intercepting dissolved organic matter, high-quality direct drinking water is output from the treated water outlet 6. The pressure blocking mechanism 7 monitors the pressure of the adsorption flow channel throughout the process, realizing overpressure protection to prevent excessive pressure inside the adsorption and interception mechanism 5. In conjunction with the pressure blocking mechanism 7, the water inlet is blocked, and the user is promptly reminded to replace the internal filter element.

[0023] Example 2 Reference Figures 2-3 A direct drinking water dissolved organic matter adsorption and interception treatment system includes an installation mechanism 3 comprising a clamp sleeve 301. The top of the clamp sleeve 301 is provided with nut clamps 302 evenly distributed around the central axis of the clamp sleeve 301. Each nut clamp 302 has an external tightening thread 303 on one side of its outer wall, a limiting block 304 on the top of each nut clamp 302, and internal protrusions 305 evenly distributed from top to bottom on one side of its inner wall. A tightening nut 306 is fitted onto the outer wall of the nut clamp 302, and an internal tightening thread 307 is provided on the inner wall of the tightening nut 306. Multiple external tightening threads 303 on the outer walls of the nut clamps 302 form a complete tightening thread. The tightening nut 306 is threadedly connected to the complete tightening thread formed by the internal tightening thread 307 and the multiple external tightening threads 303, thus threading the nut clamps 302 onto the outer walls of the multiple nut clamps 302.

[0024] The clamp sleeve 301 is cylindrical in shape. Multiple nut clamps 302 are evenly distributed around its central axis at the top of the clamp sleeve 301. The nut clamps 302 are spaced apart, forming a segmented structure with a certain degree of radial elasticity. Each nut clamp 302 has a section of tightening external thread 303 on its outer wall. When multiple nut clamps 302 are joined together, the threaded section on the outer wall of each nut clamp 302 forms a complete tightening thread. Each nut clamp 302 has a limiting block 304 at its top to prevent the nut from being over-screwed. The inner wall of each nut clamp 302 has evenly arranged inner protrusions 305 from top to bottom to increase clamping capacity. Due to friction, a tightening nut 306 is fitted onto the outside of multiple nut clamps 302. The inner wall of the tightening nut 306 is machined with a tightening internal thread 307. During installation, simply insert the water inlet pipe into the inner hole formed by the multiple nut clamps 302, and then screw the tightening nut 306 from top to bottom. The tightening nut 306 is threadedly connected to the outer wall of the multiple nut clamps 302 through its tightening internal thread 307. As the tightening nut 306 is continuously tightened, it will evenly compress all the nut clamps 302 towards the center, causing them to contract radially. This, in turn, firmly holds the internal pipe through the inner protrusion 305, completing the sealing and fixing.

[0025] Example 3 Reference Figures 5-7 A direct drinking water dissolved organic matter adsorption and interception treatment system includes a ball valve mechanism 4 comprising a rotating part 401. A ball valve body 402 is located at one end of the rotating part 401 near the direct drinking water organic matter adsorption and interception faucet 1. A raw water passage 403 is horizontally penetrating inside the ball valve body 402, and the raw water passage 403 and the rotating part 401 are parallel to each other. A purified water passage 404 is vertically penetrating inside the ball valve body 402, and the purified water passage 404 and the rotating part 401 are perpendicular to each other. The purified water passage 404 is not connected to the raw water passage 403, and the purified water passage 404 enters from the top of the ball valve body 402 and exits from the side of the ball valve body 402 away from the rotating part 401. The ball valve body 402, the raw water passage 403, and the purified water passage 404 are all located within the ball valve groove 9.

[0026] The ball valve mechanism 4 consists of a rotating part 401 and a ball valve body 402. The ball valve body 402 has two non-communicating channels: a horizontal raw water channel 403 parallel to the rotating part 401 and a vertical purified water channel 404 perpendicular to the rotating part 401. The entire ball valve mechanism 4 is installed in the ball valve slot 9 and the water path switching between raw water and purified water is realized by rotation.

[0027] Example 4 Reference Figure 2 , Figure 4 , Figure 8 , Figure 9 and Figure 10A direct drinking water dissolved organic matter adsorption and interception treatment system includes an adsorption interception mechanism 5 comprising an adsorption interception chamber 501. The top of the adsorption interception chamber 501 is provided with a removable outer cover 504. The top of the inner wall of the adsorption interception chamber 501 is provided with a surrounding adsorption interception internal thread 502. The bottom of the outer wall of the removable outer cover 504 is provided with a surrounding adsorption interception external thread 505. The adsorption interception chamber 501 is connected to the removable outer cover 504 via the threaded connection of the adsorption interception internal thread 502 and the adsorption interception external thread 505. The bottom of the adsorption interception chamber 501 is provided with an annular filter element mounting ring 506, and the top of the filter element mounting ring 506 is provided with an activated carbon filter element 503. The activated carbon filter element 503 has an external thread 508 on the bottom of its outer wall and an internal thread 507 on the inner wall of its mounting ring 506. The activated carbon filter element 503 is threadedly connected to the mounting ring 506 through the engagement of the external thread 508 and the internal thread 507. The activated carbon filter element 503 also includes an activated carbon filter element shell 5031. The activated carbon filter element shell 5031 contains uniformly stacked activated carbon layers 5032. Each of the activated carbon layers 5032 has a filter element flat membrane 5033 between them. The activated carbon filter element shell 5031 contains an outlet layer 5034 between the two ends near the mounting ring 506.

[0028] The adsorption interception chamber 501 serves as the main container, with a removable outer cover 504 at its top opening. To achieve a secure connection and facilitate disassembly and assembly, the top of the inner wall of the adsorption interception chamber 501 is machined with a surrounding internal adsorption interception thread 502, while the bottom of the outer wall of the removable outer cover 504 has a corresponding external adsorption interception thread 505. The two are connected by threaded engagement to achieve a reusable, sealed connection. At the bottom of the adsorption interception chamber 501, there is an annular filter element mounting ring 506. The inner wall of this mounting ring is machined with an internal mounting ring thread 507 for fixing the activated carbon filter element 503. The activated carbon filter element 503 is cylindrical or tubular in shape, and its bottom outer wall has an external filter element thread 508. The activated carbon filter element 503 can be screwed and fixed onto the filter element mounting ring 506 by the engagement of the external thread 508 of the filter element and the internal thread 507 of the mounting ring, ensuring that the filter element is stable in the chamber and that water flow will not leak from the bypass. The activated carbon filter element housing 5031 provides structural support and accommodates the internal filter media. The activated carbon layer 5032 is located inside the activated carbon filter element housing 5031 and has multiple layers of activated carbon evenly stacked and distributed, which are used to adsorb residual chlorine, organic matter, and odors. The filter element flat sheet membrane 5033 is set between adjacent activated carbon layers 5032, which plays the role of separation and secondary filtration, preventing the loss of activated carbon particles, and further intercepting small impurities. The water outlet layer 5034 is located inside the activated carbon filter element housing 5031 near the filter element mounting ring 506. The purified water after filtration by activated carbon and flat sheet membrane is collected through this layer.

[0029] Example 5 Referring to 13, a direct drinking water dissolved organic matter adsorption and interception treatment system includes a pressure blocking mechanism 7 comprising a pressure blocking shell 701, three pressure grooves 702 extending through the pressure blocking shell 701, and a blocking plate groove 703 extending through the pressure blocking shell 701 near the installation mechanism 3, wherein the pressure grooves 702 and the blocking plate grooves 703 are interconnected, each pressure groove 702 is provided with a connecting rod 705, and each connecting rod 705 near the adsorption and interception mechanism 5 is provided with a pressure abutment block 706, and the blocking plate groove 703 is provided with a blocking plate 704, wherein the connecting rod 705 extends towards the installation mechanism 3 and connects with the blocking plate 704.

[0030] The pressure blocking mechanism 7 consists of a pressure blocking housing 701, three pressure grooves 702, a blocking plate groove 703, three connecting rods 705 with pressure abutment blocks 706, and a blocking plate 704. The pressure grooves 702 are connected to the blocking plate groove 703. One end of the connecting rod 705 is connected to the pressure abutment block 706 near the adsorption interception mechanism 5, and the other end extends to the blocking plate groove 703 and is fixedly connected to the blocking plate 704. When the water pressure is too high, the pressure abutment block 706 is forced to push the connecting rod 705, which in turn drives the blocking plate 704 to move, blocking the water flow, playing an overpressure protection role, and reminding the user to replace the filter element in time.

[0031] Example 6 Reference Figure 12 A direct drinking water dissolved organic matter adsorption and interception treatment system includes a sealing mechanism 8 comprising a rubber base pad 801, which is annular in shape. The top of the rubber base pad 801 has evenly distributed clearance grooves 802. The inner wall of the rubber base pad 801 has evenly distributed eight-part ring plates 803. Each of the eight-part ring plates 803 has a rotating abutment claw 806 rotatably connected to it. The outer side of the top of each abutment claw 806 has an outwardly expanding end 807. On the same side of the abutment claw 806 away from the outwardly expanding end 807, there is an abutment compression end 808. The outer wall of the top of the abutment claw 806 is provided with a surrounding rubber sealing ring 804, which is annular in shape. One side of the inner wall of the rubber sealing ring 804 has an annular recessed groove 805, and the outwardly expanding ends 807 are all located within the recessed groove 805 and engaged.

[0032] The sealing mechanism 8 consists of an annular rubber base pad 801, evenly distributed eight-part ring plates 803, eight rotatable abutting rotating claws 806, and an annular rubber sealing ring 804 with an inner groove 805. Each abutting rotating claw 806 has an outwardly expanding end 807 at one end, which is inserted into the inner groove 805, and an abutting compression end 808 at the other end. When axial pressure is applied to the abutting compression end 808, the outwardly expanding end 807 is pushed outward by lever rotation to open the rubber sealing ring 804, thereby achieving radial compression to enhance the seal. After the pressure is removed, it elastically resets. The mechanical linkage converts the axial force into a radial expansion force, improving the reliability of the seal.
