Description

Technical Field

[0001] The present invention relates to the technical field of water purification, in particular to a pure water purification device and a pure water purification treatment method thereof. Background Art

[0002] Water hardening is a phenomenon in which the content of cations such as calcium ions and magnesium ions in water increases due to certain reasons, thereby increasing the hardness of water. The total amount of calcium and magnesium ions contained in water was formerly called the total hardness of water. According to cations, it can be further divided into calcium hardness and magnesium hardness. Water with high hardness is not suitable for industrial and daily life use. In order to ensure that the hardness of water to be used in industry and daily life is within the safety standard range, people currently use various methods and devices to soften hardened water. According to a Chinese patent with application publication number CN109694148B, a pure water purification device and a pure water purification method thereof are disclosed. A water hardness meter is used to control whether the first liquid inlet water pipe and the second liquid inlet water pipe are connected to the liquid main water pipe. The present invention can control whether the water body needs to be softened and the most suitable amount of softening through a water hardness meter, which saves costs and improves purification efficiency.

[0003] The above-mentioned pure water purification device relies on the natural flow of water to filter impurities, resulting in a small flow rate of water through the filter, a small amount of pure water produced per unit time, water accumulation at the water inlet, and unsatisfactory pure water production efficiency.

[0035] A pure water purification method for a pure water purification device comprises the following processing steps:

[0036] S1. The clean water enters the interior of the shutoff valve body through multiple water supply pipes, and enters the interior of the water retaining station ring through the shutoff valve body and the water inlet pipe, and is located in the internal area of ​​the rubber water squeezing sleeve;

[0037] S2, the central vertical axis is driven to rotate by the output shaft of the reduction motor, thereby driving the upper and lower cross angle plates and four squeezing rollers to rotate together, rolling the outer walls of the four rubber squeezing jackets, so that the water in the inner area of ​​the rubber squeezing jackets can quickly pass through the filter holes and enter the area between the pre-treatment tank and the water retaining station circle;

[0038] S3. The clean water after the initial filtration in the pre-treatment tank is pumped through a hose to the first filter element on the left through a first-level booster pump for fine filtration, and flows out through the output end of the first filter element on the left, and enters a second-level booster pump located at the left end through a hose. The second-level booster pump is pressurized so that the clean water after the first-level fine filtration quickly enters a filter element located in the middle, is finely filtered again, and flows out through the output end of the filter element again, and is discharged into the second-level booster pump at the right end through a hose. After being pressurized by the second-level booster pump at the right end, the clean water after the second-level fine filtration is transported to the rightmost filter element for final fine filtration to obtain pure water.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] 1. In the present invention, the central vertical axis is driven to rotate by the output shaft of the reduction motor. The rotation of the central vertical axis drives four water squeezing rollers to rotate through the connection of the upper and lower cross angle plates, rolling the outer walls of the four rubber water squeezing jackets, causing the rubber water squeezing jackets to shrink, and pressurizing the tap water in the internal area thereof, which can increase the flow rate of the tap water inside the water retaining station circle through the filter holes for initial filtration, thereby improving the initial filtration efficiency of pure water.

[0041] 2. In the present invention, the elastic support arc strips on the inner side of the rubber water squeezing jacket can prevent the rubber water squeezing jacket from being pushed to one side by the water squeezing roller, ensuring that the rubber water squeezing jacket always contracts in the direction of the filter hole, thereby ensuring the pressurization effect on the tap water. In addition, during the contraction of the rubber water squeezing jacket in the direction of the filter hole, the elastic support arc strips are affected by the contraction of the rubber water squeezing jacket and slide along the square hole, thereby not interfering with the normal contraction of the rubber water squeezing jacket. When the water squeezing roller rolls off the outer wall of the rubber water squeezing jacket, the elastic support arc strips recover under the action of their own rebound force, and slide back along the inner wall of the square hole to the initial position again, lifting the rubber water squeezing jacket, providing support to the rubber water squeezing jacket, and accelerating the rebound efficiency of the rubber water squeezing jacket.

[0042] 3. In the present invention, during the period when the water squeezing roller rolls the rubber water squeezing jacket, the rotation of the central vertical axis just drives the cam to rotate together until the four protruding parts contact the ends of the four push rods, thereby pushing the four push rods in the direction away from the central vertical axis. The movement of the push rod drives the plunger to move together, so that the plunger is intercepted inside the shut-off valve body. At the same time, the spring is stretched and stored, and the plunger is intercepted inside the shut-off valve body, resulting in the inside of the shut-off valve body being intercepted. The tap water that flows into the inside of the shut-off valve body through the water supply pipe cannot continue to be discharged into the inside of the water inlet pipe, and cannot enter the inside of the water retaining station ring. In other words, during the period when the water squeezing roller rolls the rubber water squeezing jacket and contracts, the device will not continue to replenish tap water to the inside of the rubber water squeezing jacket, so as to avoid the rubber water squeezing jacket from being subjected to excessive load and ruptured.

DETAILED DESCRIPTION

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] See also Figures 1 to 11 The technical solution provided by the present invention specifically includes the following embodiments:

[0057] A pure water purification device includes a square tube rack 100, a pre-filter unit 200 and a cut-off unit 300. The pre-filter unit 200 is fixedly arranged at the inner left end of the square tube rack 100, and the pre-filter unit 200 is used for the pre-filtering of pure water. The cut-off unit 300 is fixedly arranged at the inner upper end of the pre-filter unit 200 and is used for the water inlet control of the pre-filter unit 200. Locking universal wheels 700 are fixedly arranged at the four corners of the bottom of the square tube rack 100.

[0058] For further details, please refer to Figure 3 to Figure 6 As shown:

[0059] The pre-filter unit 200 includes a pre-treatment tank 201, a water retaining ring 202, filter holes 203, a rubber water squeezing jacket 204, a water outlet 2012, a flange pipe 2013, and a water inlet pipe 2014. The pre-treatment tank 201 is fixedly installed at the left end of the interior of the square tube frame 100, and the water retaining ring 202 is fixedly installed inside the pre-treatment tank 201. The outer wall of the water retaining ring 202 is provided with a plurality of filter holes 203, and the filter holes 203 are used for filtering large particles in the water. The rubber water squeezing jacket 204 is fixedly installed. On the inner wall of the water retaining ring 202, there are four rubber water squeezing sleeves 204 distributed in a circular array, the water outlet 2012 is opened through the lower part of the outer wall of the pre-treatment tank body 201, the flange pipe 2013 is fixedly installed on the outer wall of the pre-treatment tank body 201, and is located outside the opening of the flange pipe 2013, the water inlet pipe 2014 is fixedly installed on the top of the water retaining ring 202, and there are four water inlet pipes 2014, and the positions of the four water inlet pipes 2014 correspond one by one to the positions of the four rubber water squeezing sleeves 204.

[0060] Specifically, after the external tap water flows into the water inlet pipe 2014 through the intercepting unit 300, it is discharged into the interior of the water retaining station circle 202 through the water inlet pipe 2014 and is located in the internal area of ​​the four rubber water squeezing sleeves 204. The tap water in the internal area of ​​the rubber water squeezing sleeve 204 passes through the filter hole 203 to initially filter out some large particles, and then enters the area between the pre-treatment tank body 201 and the water retaining station circle 202 to achieve preliminary filtration of the tap water.

[0061] For further details, please refer to Figure 6, Figure 7 As shown:

[0062] The pre-filter unit 200 also includes a central vertical axis 205, a cross-angle plate 206, a water squeezing roller 207 and a reduction motor 208. The central vertical axis 205 is vertically arranged and rotatably installed inside the water retaining ring 202. The central vertical axis 205 passes through the bottom of the pre-treatment tank body 201. The cross-angle plate 206 is fixedly installed on the upper part of the outer wall of the central vertical axis 205 and the lower part of the outer wall. The water squeezing roller 207 is rotatably installed between the upper and lower central vertical axes 205, and there are four of them. The reduction motor 208 is fixedly installed on the bottom of the pre-treatment tank body 201, and the output shaft of the reduction motor 208 is fixedly connected to the bottom of the central vertical axis 205 through a coupling.

[0063] Specifically, the central vertical axis 205 is driven to rotate by the output shaft of the reduction motor 208. The rotation of the central vertical axis 205 drives the four water squeezing rollers 207 to rotate through the connection between the upper and lower cross angle plates 206, rolling the outer walls of the four rubber water squeezing sleeves 204, causing the rubber water squeezing sleeves 204 to shrink, thereby pressurizing the tap water in its internal area, which can increase the flow rate of the tap water inside the water retaining station circle 202 through the filter hole 203 for initial filtration, thereby improving the initial filtration efficiency of pure water.

[0064] For further details, please refer to Figure 4 , Figure 7 As shown:

[0065] The pre-filter unit 200 also includes a square hole 209, an elastic support arc strip 2010 and a limit block 2011. The square hole 209 is opened on the outer wall of the water retaining ring 202 and extends to the inside of the water retaining ring 202. The elastic support arc strip 2010 is slidably installed inside the square hole 209. The elastic support arc strip 2010 is arranged in an arch shape, and the arch surface of the elastic support arc strip 2010 abuts against the inner wall of the rubber water extrusion sleeve 204. The limit blocks 2011 are fixedly installed at both ends of the elastic support arc strip 2010.

[0066] Specifically, during the process of the water squeezing roller 207 rolling and shrinking the rubber water squeezing jacket 204, the elastic support arc strip 2010 can prevent the rubber water squeezing jacket 204 from being pushed to one side by the water squeezing roller 207, thereby ensuring that the rubber water squeezing jacket 204 always shrinks toward the filter hole 203, thereby ensuring the pressurization effect of the tap water. In addition, during the process of the rubber water squeezing jacket 204 shrinking toward the filter hole 203, the elastic support arc strip 2010 is supported by the rubber water squeezing jacket 204. The elastic support arc strip 2010 is affected by the contraction of the rubber water squeezing jacket 204 and slides along the square hole 209, thereby not interfering with the normal contraction of the rubber water squeezing jacket 204. When the water squeezing roller 207 rolls away from the outer wall of the rubber water squeezing jacket 204, the elastic support arc strip 2010 recovers under the action of its own resilience and slides back along the inner wall of the square hole 209 to the initial position, lifting the rubber water squeezing jacket 204. While providing support to the rubber water squeezing jacket 204, it can also accelerate the rebound efficiency of the rubber water squeezing jacket 204.

[0067] For further details, please refer to Fig. 9 As shown:

[0068] The shutoff unit 300 includes a shutoff valve body 301, a plunger 302, a push rod 303, a spring 304, a cam 305 and a water supply pipe 306. The shutoff valve body 301 is fixedly installed on the top of the water inlet pipe 2014, and the plunger 302 is horizontally slidably installed inside the shutoff valve body 301. The outer wall of the plunger 302 fits the inner wall of the shutoff valve body 301. The push rod 303 is fixedly installed inside the plunger 302 and movably extends to the periphery of the shutoff valve body 301. The axis of the push rod 303 is perpendicular to the axis of the central vertical axis 205. The spring 304 is fixedly arranged inside the shut-off valve body 301 and is located on the periphery of the push rod 303. The spring 304 is fixedly installed between the plunger 302 and the inner wall of one side of the shut-off valve body 301. The cam 305 is fixedly installed on the outer wall of the central vertical axis 205 and is located at the end of the push rod 303. The outer edge of the cam 305 abuts against the end of the push rod 303. The water supply pipe 306 is fixedly installed on the top of the shut-off valve body 301. The water supply pipe 306 runs through the interior of the pre-treatment tank 201 and extends to the periphery of its top.

[0069] Specifically, when the squeezing roller 207 rolls the rubber squeezing sleeve 204, the central vertical shaft 205 rotates and just drives the cam 305 to rotate together until the four protruding parts contact the ends of the four pushing rods 303, thereby pushing the four pushing rods 303 in the direction away from the central vertical shaft 205. The movement of the pushing rod 303 drives the plunger 302 to move together, so that the plunger 302 is intercepted in the interior of the shut-off valve body 301. At the same time, the spring 304 is stretched and stored, and the plunger 302 is intercepted in the interior of the shut-off valve body 301, resulting in the shut-off valve body 301 being intercepted. The tap water that flows into the shut-off valve body 301 through the water supply pipe 306 cannot continue to be discharged into the interior of the water inlet pipe 2014, and cannot enter the interior of the water retaining ring 202. In other words, when the squeezing roller 207 rolls the rubber squeezing sleeve 204 and contracts, the device is not The rubber water squeezing sleeve 204 will continue to be replenished with tap water to prevent the rubber water squeezing sleeve 204 from being broken due to excessive load. When the water squeezing roller 207 rolls away from the outer wall of the rubber water squeezing sleeve 204, the central vertical axis 205 just drives the cam 305 to rotate until the four protruding parts are misaligned with the ends of the four push rods 303, thereby terminating the thrust effect on the push rods 303. The resilience of the spring 304 is released, pushing the push rods 303 together with the plunger 302 to move in the direction close to the central vertical axis 205, thereby terminating the interception effect on the interior of the shut-off valve body 301. The tap water can smoothly pass through the interior of the shut-off valve body 301 and enter the interior of the water inlet pipe 2014 again, and continue to be discharged into the interior of the water retaining station circle 202 and located in the internal area of ​​the rubber water squeezing sleeve 204. The above process is repeated to accelerate the primary filtration efficiency of pure water and improve the production capacity of pure water.

[0070] For further details, please refer to Fig.10 , Fig.11 As shown:

[0071] A plurality of filter cartridges 400 arranged in parallel on the left and right are fixedly arranged at the inner right end of the square tube rack 100, a primary booster pump 500 is fixedly arranged at the inner right lower end of the square tube rack 100, an input end of the primary booster pump 500 is connected to the end of the flange pipe 2013 via a hose, and an output end of the primary booster pump 500 is connected to an input end of a filter cartridge 400 at the far left end via a hose;

[0072] Two secondary booster pumps 600 are fixedly arranged in parallel on the left and right sides at the inner right end of the square tube rack 100, wherein the input end of a secondary booster pump 600 located on the left is connected to the output end of a filter element 400 at the far left through a hose, and the output end of the secondary booster pump 600 is connected to the input end of a filter element 400 at the middle position through a hose, and the output end of the filter element 400 is connected to the input end of a secondary booster pump 600 on the right through a hose, and the output end of a secondary booster pump 600 located on the right is connected to the input end of a filter element 400 at the far right through a hose.

[0073] Specifically, the clean water after the initial filtration in the pre-treatment tank 201 is pumped through a hose to the first filter element 400 on the left through the first booster pump 500 for fine filtration, and flows out through the output end of the first filter element 400 on the left, and enters the interior of a secondary booster pump 600 located at the left end through a hose. The secondary booster pump 600 is pressurized so that the clean water after the first-level fine filtration quickly enters the interior of a filter element 400 located in the middle, is finely filtered again, and flows out through the output end of the filter element 400 again, and is discharged into the interior of the secondary booster pump 600 at the right end through a hose. After being pressurized by the secondary booster pump 600 at the right end, the clean water after the second-level fine filtration is transported to the interior of a filter element 400 at the far right for final fine filtration to obtain pure water.

[0074] A pure water purification method for a pure water purification device comprises the following processing steps:

[0075] S1, the purified water enters the interior of the shut-off valve body 301 through the multiple water supply pipes 306, and enters the interior of the water retaining ring 202 through the shut-off valve body 301 and the water inlet pipe 2014, and is located in the inner area of ​​the rubber water squeezing sleeve 204;

[0076] S2, the central vertical shaft 205 is driven to rotate by the output shaft of the reduction motor 208, thereby driving the upper and lower cross angle plates 206 and the four squeezing rollers 207 to rotate together, rolling the outer walls of the four rubber squeezing jackets 204, so that the water in the inner area of ​​the rubber squeezing jacket 204 is quickly filtered through the filter holes 203 and then enters the area between the pre-treatment tank body 201 and the water retaining station circle 202;

[0077] S3. The clean water after the initial filtration in the pre-treatment tank 201 is pumped through a hose to the first filter element 400 on the left through the first booster pump 500 for fine filtration, and flows out through the output end of the first filter element 400 on the left, and enters the second booster pump 600 located at the left end through the hose. The second booster pump 600 is pressurized so that the clean water after the first fine filtration quickly enters the filter element 400 located in the middle, is finely filtered again, and flows out through the output end of the filter element 400 again, and is discharged into the second booster pump 600 at the right end through the hose. After being pressurized by the second booster pump 600 at the right end, the clean water after the second fine filtration is transported to the rightmost filter element 400 for final fine filtration to obtain pure water.

[0078] When the pure water purification device of the present scheme is working, the top of the four water supply pipes 306 are connected to the tap water pipe, and the tap water flows into the interior of the four shut-off valve bodies 301 through the four water supply pipes 306, and then the tap water flows into the interior of the water retaining station circle 202 through the water inlet pipe 2014, and is located in the internal area of ​​the four rubber water squeezing sleeves 204. The tap water in the internal area of ​​the rubber water squeezing sleeve 204 passes through the filter hole 203 to filter out some large particles, and then enters the area between the pre-treatment tank body 201 and the water retaining station circle 202. At the same time, the central vertical shaft 205 is driven to rotate by the output shaft of the reduction motor 208. The rotation of the central vertical shaft 205 drives the four water squeezing rollers 207 to rotate through the connection of the upper and lower cross angle plates 206, and rolls the outer walls of the four rubber water squeezing sleeves 204, causing the rubber water squeezing sleeves 204 to shrink, and pressurizes the tap water in its internal area, which can increase the flow rate of the tap water in the water retaining station circle 202 through the filter hole 203 for initial filtration, thereby improving the water retention capacity. The filtration efficiency is improved, and in the process of the water squeezing roller 207 rolling the rubber water squeezing jacket 204 to shrink, the elastic support arc strip 2010 on the inner side of the rubber water squeezing jacket 204 can prevent the rubber water squeezing jacket 204 from being pushed to one side by the water squeezing roller 207, ensuring that the rubber water squeezing jacket 204 always shrinks toward the direction of the filter hole 203, thereby ensuring the pressurization effect on the tap water, and in the process of the rubber water squeezing jacket 204 shrinking toward the direction of the filter hole 203, the elastic support arc strip 2010 ... thereby ensuring that the rubber water squeezing jacket 204 always shrinks toward the direction of the filter hole 203, thereby ensuring the pressurization effect on the tap water, and in the process of the rubber water squeezing jacket 204 shrinking toward the direction of the filter hole 203, the elastic support arc strip 2010 can prevent the rubber water squeezing jacket 204 from being pushed to the inner side of the rubber water squeezing jacket 204, 0 is subjected to the contraction of the rubber water squeezing jacket 204 and slides along the square hole 209, so as not to interfere with the normal contraction of the rubber water squeezing jacket 204. When the water squeezing roller 207 rolls off the outer wall of the rubber water squeezing jacket 204, the elastic support arc strip 2010 recovers under the action of its own resilience and slides back along the inner wall of the square hole 209 to the initial position again, lifting the rubber water squeezing jacket 204, providing support to the rubber water squeezing jacket 204 and accelerating the rebound efficiency of the rubber water squeezing jacket 204;

[0079] When the squeezing roller 207 rolls the rubber squeezing sleeve 204, the central vertical shaft 205 rotates and just drives the cam 305 to rotate together until the four protruding parts contact the ends of the four pushing rods 303, thereby pushing the four pushing rods 303 in the direction away from the central vertical shaft 205. The movement of the pushing rod 303 drives the plunger 302 to move together, so that the plunger 302 is intercepted in the interior of the shut-off valve body 301. At the same time, the spring 304 is stretched and stored, and the plunger 302 is intercepted in the interior of the shut-off valve body 301, resulting in the shut-off valve body 301 being intercepted. The tap water that flows into the shut-off valve body 301 through the water supply pipe 306 cannot continue to be discharged into the interior of the water inlet pipe 2014, and cannot enter the interior of the water retaining station circle 202. In other words, the squeezing roller 207 will not continue to be discharged into the interior of the water inlet pipe 2014 during the contraction of the rolling rubber squeezing sleeve 204. The rubber water squeezing sleeve 204 is continuously replenished with tap water to prevent the rubber water squeezing sleeve 204 from being broken due to excessive load. When the water squeezing roller 207 rolls away from the outer wall of the rubber water squeezing sleeve 204, the central vertical axis 205 just drives the cam 305 to rotate until the four protruding parts are misaligned with the ends of the four push rods 303, ending the thrust effect on the push rods 303. The resilience of the spring 304 is released, pushing the push rods 303 together with the plunger 302 to move in the direction close to the central vertical axis 205, ending the interception effect on the inside of the shut-off valve body 301. The tap water can smoothly pass through the inside of the shut-off valve body 301 and enter the inside of the water inlet pipe 2014 again, and is continuously discharged into the inside of the water retaining station circle 202 and located in the internal area of ​​the rubber water squeezing sleeve 204. The above process is repeated to accelerate the primary filtration efficiency of pure water and improve the production capacity of pure water.

[0080] The clean water after the initial filtration in the pre-treatment tank 201 is pumped through a hose to the first filter element 400 on the left by the first-level booster pump 500 for fine filtration, and flows out through the output end of the first filter element 400 on the left, and enters the interior of a secondary booster pump 600 located at the left end through a hose. The secondary booster pump 600 is pressurized so that the clean water after the first-level fine filtration quickly enters the interior of a filter element 400 located in the middle, is finely filtered again, and flows out through the output end of the filter element 400 again, and is discharged into the interior of the secondary booster pump 600 at the right end through a hose. After being pressurized by the secondary booster pump 600 at the right end, the clean water after the second-level fine filtration is transported to the interior of a filter element 400 at the far right for final fine filtration to obtain pure water.

[0081] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
