Description

Technical Field

[0001] The present invention relates to the technical field of water purification, and specifically 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 the water. The total amount of calcium and magnesium ions contained in water was formerly called the total hardness of water. It can be further divided into calcium hardness and magnesium hardness according to cations. Water with high hardness is not suitable for industrial and daily life use. In order to ensure that the hardness of the water to be used in industry and daily life is within the safe standard range, at present, people use various methods and devices to soften the hardened water. According to a Chinese patent with the application publication number CN109694148B, a pure water purification device and a pure water purification treatment method thereof are disclosed. The first liquid inlet branch pipe and the second liquid inlet branch pipe are respectively controlled whether to communicate with the main water pipe through a water quality hardness measuring instrument. The present invention can regulate whether the water body needs to be softened and the most suitable amount of softening through the water quality hardness measuring instrument, playing a role in saving costs and improving purification efficiency;

[0003] The above pure water purification device relies on the natural flow mode of the water body to filter impurities, resulting in a small flow rate of the water body through the filter screen, a small amount of pure water produced per unit time, and easy water accumulation at the water inlet. The pure water production efficiency is not ideal. For this reason, we propose a pure water purification device and a pure water purification treatment method thereof to solve the above technical problems. Summary of the Invention

[0034] As a preferred solution of the present invention, locking universal wheels are fixedly arranged at the four corners of the bottom of the square pipe frame.

[0035] A pure water purification treatment method for a pure water purification device includes the following treatment steps:

[0036] S1. The purified water enters the inside of the shut-off valve body through a plurality of water supply pipes, and enters the inside of the water retaining station ring through the shut-off valve body and the water inlet pipe, and is located in the inner area of the rubber water squeezing sleeve.

[0037] S2. The output shaft of the reduction motor is driven to rotate the central vertical shaft, thereby driving the upper and lower cross angle plates and the four water squeezing rollers to rotate together, rolling the outer walls of the four rubber water squeezing sleeves, so that the water entering the inner area of the rubber water squeezing sleeve quickly passes through the filter holes and enters the area between the pre-treatment tank body and the water retaining station ring.

[0038] S3. The preliminarily filtered purified water inside the pre-treatment tank body is pumped into the interior of the leftmost first filter element through a hose by a primary booster pump for fine filtration, and flows out through the output end of the leftmost first filter element, enters into a secondary booster pump located at the left end through the hose, is pressurized by this secondary booster pump, so that the purified water after primary fine filtration quickly enters into the interior of a filter element located in the middle for secondary fine filtration, and after flowing out through the output end of this filter element again, is discharged into the interior of the secondary booster pump located at the right end through the hose. After being pressurized by the secondary booster pump at the right end, the purified water after secondary fine filtration is conveyed into the interior of the rightmost filter element for final fine filtration to obtain pure water.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] 1. In the present invention, the output shaft of the reduction motor drives the central vertical shaft to rotate. The rotation of the central vertical shaft drives the rotation of the four water squeezing rollers through the connection of the upper and lower cross angle plates, rolls the outer walls of the four rubber water squeezing sleeves, causing the rubber water squeezing sleeves to contract, pressurizing the tap water in their internal areas, which can increase the flow rate of the tap water passing through the filter holes for preliminary filtration inside the water retaining station ring, and thus improve the preliminary filtration efficiency of pure water.

[0041] 2. In the present invention, through the elastic support of the elastic support arc strips on the inner side of the rubber water squeezing sleeves, it can prevent the rubber water squeezing sleeves from being pushed to one side by the water squeezing rollers, ensuring that the rubber water squeezing sleeves always contract towards the direction of the filter holes, thereby ensuring the pressurization effect on the tap water. Moreover, during the process of the rubber water squeezing sleeves contracting towards the direction of the filter holes, the elastic support arc strips are subjected to the contraction effect of the rubber water squeezing sleeves and slide along the square holes, so as not to interfere with the normal contraction of the rubber water squeezing sleeves. When the water squeezing rollers roll away from the outer walls of the rubber water squeezing sleeves, the elastic support arc strips recover under the action of their own resilience and slide reversely along the inner walls of the square holes to the initial position, jacking up the rubber water squeezing sleeves, providing support for the rubber water squeezing sleeves while also accelerating the resilience efficiency of the rubber water squeezing sleeves.

[0042] 3. In the present invention, during the period when the water squeezing rollers roll and press the rubber water squeezing sleeves, the rotation of the central vertical shaft just drives the cam to rotate together until the four convex parts contact the ends of the four push rods, thereby pushing the four push rods in the direction away from the central vertical shaft. The movement of the push rods drives the plunger to move together, intercepting the plunger inside the intercepting valve body. At the same time, the spring is stretched and stores energy. And when the plunger is intercepted inside the intercepting valve body, the interior of the intercepting valve body is intercepted, and the tap water flowing into the interior of the intercepting valve body through the water supply pipe cannot continue to be discharged into the water inlet pipe and further cannot enter into the interior of the water retaining station ring. That is to say, during the period when the water squeezing rollers roll and press the rubber water squeezing sleeves to contract, the device will not continue to supplement tap water into the interior of the rubber water squeezing sleeves, avoiding the rubber water squeezing sleeves from bursting due to excessive load.

Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0056] Please refer to Figures 1 to 11 , the technical solutions provided by the present invention specifically include the following embodiments:

[0057] A purification device for pure water includes a square pipe rack 100, a pre-filter unit 200, and a throttling unit 300. The pre-filter unit 200 is fixedly arranged at the left end inside the square pipe rack 100 and is used for the primary filtration of pure water. The throttling unit 300 is fixedly arranged at the upper end inside the pre-filter unit 200 and is used for controlling the water inlet of the pre-filter unit 200. Locking universal wheels 700 are fixedly arranged at the four corners of the bottom of the square pipe rack 100.

[0058] Furthermore, specifically referring to Figures 3 to 6 as shown:

[0059] The pre-filter unit 200 includes a pre-treatment tank body 201, a water retaining ring 202, filter holes 203, a rubber water squeezing sleeve 204, a water outlet hole 2012, a flange pipe 2013, and a water inlet pipe 2014. The pre-treatment tank body 201 is fixedly installed at the left end inside the square pipe rack 100. The water retaining ring 202 is fixedly installed inside the pre-treatment tank body 201. A plurality of filter holes 203 are formed in the outer wall of the water retaining ring 202 and are used for filtering large particles in water. The rubber water squeezing sleeve 204 is fixedly installed on the inner wall of the water retaining ring 202 and the number is four. The four rubber water squeezing sleeves 204 are arranged in a circumferential array. The water outlet hole 2012 is formed 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 around the opening of the water outlet hole 2012. The water inlet pipe 2014 is fixedly installed at the top of the water retaining ring 202 and the number is four. The positions of the four water inlet pipes 2014 correspond to the positions of the four rubber water squeezing sleeves 204 one by one.

[0060] Specifically, after the external tap water flows into the water inlet pipe 2014 through the throttling unit 300, it is discharged into the inside of the water retaining ring 202 through the water inlet pipe 2014 and is located in the inner area of the four rubber water squeezing sleeves 204. The tap water located in the inner area of the rubber water squeezing sleeve 204 is initially filtered through the filter holes 203 to remove some large particles and then enters the area between the pre-treatment tank body 201 and the water retaining ring 202 to achieve the preliminary filtration of the tap water.

[0061] Furthermore, specifically referring to Figure 6, Figure 7 as shown

[0062] The pre-filter unit 200 further includes a central vertical shaft 205, a cross-angle plate 206, a water squeezing roller 207 and a reduction motor 208. The central vertical shaft 205 is vertically arranged and rotatably installed inside the water retaining ring 202. The central vertical shaft 205 penetrates the bottom of the pre-treatment tank body 201. The cross-angle plate 206 is fixedly installed on the upper and lower outer walls of the central vertical shaft 205. The water squeezing roller 207 is rotatably installed between the upper and lower cross-angle plates 206, and the number is four. The reduction motor 208 is fixedly installed at 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 shaft 205 through a coupling.

[0063] Specifically, the output shaft of the reduction motor 208 drives the central vertical shaft 205 to rotate. 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 contract, increasing the pressure of the tap water in their internal areas, and improving the flow rate of the tap water passing through the filter holes 203 for primary filtration inside the water retaining ring 202, thereby improving the primary filtration efficiency of pure water.

[0064] Furthermore, specifically referring to Figure 4 , Figure 7 as shown

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

[0066] Specifically, during the shrinkage process of the rubber water squeezing sleeve 204 under the rolling pressure of the water squeezing roller 207, the elastic supporting arc strip 2010 can prevent the rubber water squeezing sleeve 204 from being pushed to one side by the water squeezing roller 207 through the elastic supporting effect on the inner side of the rubber water squeezing sleeve 204, ensuring that the rubber water squeezing sleeve 204 always shrinks towards the direction of the filter hole 203, thereby guaranteeing the pressurization effect on tap water. Moreover, during the process of the rubber water squeezing sleeve 204 shrinking towards the filter hole 203, the elastic supporting arc strip 2010 slides along the square hole 209 under the shrinking action of the rubber water squeezing sleeve 204, thus not interfering with the normal shrinkage of the rubber water squeezing sleeve 204. When the water squeezing roller 207 rolls away from the outer wall of the rubber water squeezing sleeve 204, the elastic supporting arc strip 2010 restores under its own resilience and slides reversely along the inner wall of the square hole 209 to the initial position, jacking up the rubber water squeezing sleeve 204. While providing support for the rubber water squeezing sleeve 204, it can also accelerate the resilience efficiency of the rubber water squeezing sleeve 204.

[0067] Further, specifically referring to Figure 9 as shown:

[0068] The intercepting unit 300 includes an intercepting valve body 301, a plunger 302, a push rod 303, a spring 304, a cam 305, and a water supply pipe 306. The intercepting valve body 301 is fixedly installed on the top of the water inlet pipe 2014. The plunger 302 is slidably installed horizontally inside the intercepting valve body 301, and the outer wall of the plunger 302 fits with the inner wall of the intercepting valve body 301. The push rod 303 is fixedly installed inside the plunger 302 and extends outwardly to the periphery of the intercepting valve body 301. The axis of the push rod 303 is perpendicular to the axis of the central vertical shaft 205. The spring 304 is fixedly arranged inside the intercepting valve body 301 and is located outside the push rod 303. The spring 304 is fixedly installed between the plunger 302 and one inner wall of the intercepting valve body 301. The cam 305 is fixedly installed on the outer wall of the central vertical shaft 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 intercepting valve body 301. The water supply pipe 306 penetrates through the inside of the pre-treatment tank body 201 and extends to the periphery of its top.

[0069] Specifically, when the water squeezing roller 207 rolls on the rubber water squeezing sleeve 204, the central vertical shaft 205 rotates just to drive the cam 305 to rotate together until the four convex parts contact the ends of the four taper rods 303, thereby pushing the four taper rods 303 away from the central vertical shaft 205. The movement of the taper rods 303 drives the plunger 302 to move together, so that the plunger 302 intercepts inside the shut-off valve body 301. At the same time, the spring 304 is stretched and stores energy. And when the plunger 302 intercepts inside the shut-off valve body 301, the inside of the shut-off valve body 301 is shut off, and the tap water flowing into the inside of the shut-off valve body 301 through the water supply pipe 306 cannot continue to drain into the inside of the water inlet pipe 2014, and even less can enter the inside of the water retaining station ring 202. That is to say, during the contraction of the rubber water squeezing sleeve 204 when the water squeezing roller 207 rolls, the device will not continue to supply tap water to the inside of the rubber water squeezing sleeve 204, avoiding the rubber water squeezing sleeve 204 from bursting 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 shaft 205 just drives the cam 305 to rotate until the four convex parts are misaligned with the ends of the four taper rods 303, ending the thrust on the taper rods 303. The resilience of the spring 304 is released, pushing the taper rods 303 together with the plunger 302 to move towards the central vertical shaft 205, ending the interception inside the shut-off valve body 301. The tap water can flow smoothly through the inside of the shut-off valve body 301, enter the inside of the water inlet pipe 2014 again, and be continuously drained into the inside of the water retaining station ring 202, and in the area inside the rubber water squeezing sleeve 204, repeating the above process to accelerate the primary filtration efficiency of pure water and improve the production capacity of pure water.

[0070] Further, specifically refer to Figure 10 、 Figure 11 as shown in:

[0071] A plurality of filters 400 arranged side by side left and right are fixedly arranged at the right end inside the square pipe frame 100. An primary booster pump 500 is fixedly arranged at the lower right end inside the square pipe frame 100. The input end of the primary booster pump 500 is connected to the end of the flange pipe 2013 through a hose, and the output end of the primary booster pump 500 is connected to the input end of the leftmost filter 400 through a hose;

[0072] Two secondary booster pumps 600 arranged side by side left and right are fixedly arranged at the right end inside the square pipe frame 100. The input end of the leftmost secondary booster pump 600 is connected to the output end of the leftmost filter 400 through a hose, and the output end of this secondary booster pump 600 is connected to the input end of the filter 400 at the middle position through a hose, and the output end of this filter 400 is connected to the input end of the rightmost secondary booster pump 600 through a hose. The output end of the rightmost secondary booster pump 600 is connected to the input end of the rightmost filter 400 through a hose.

[0073] Specifically, the purified water after primary filtration inside the pre-treatment tank body 201 is pumped into the interior of the leftmost first filter element 400 through a hose by a primary booster pump 500 for fine filtration, and flows out through the output end of the leftmost first filter element 400, enters into a secondary booster pump 600 located at the left end through a hose. After being pressurized by this secondary booster pump 600, the purified water after primary fine filtration quickly enters into the interior of a filter element 400 located in the middle for re-fine filtration. After flowing out through the output end of this filter element 400 again, it is discharged into the interior of the secondary booster pump 600 located at the right end through a hose. After being pressurized by the secondary booster pump 600 at the right end, the purified water after secondary fine filtration is transported into the interior of the rightmost filter element 400 for final fine filtration to obtain pure water.

[0074] A method for purifying pure water in a pure water purification device includes the following treatment steps:

[0075] S1. The purified water enters into the interior of the throttle valve body 301 through multiple water supply pipes 306, and enters into the interior of the water retaining station ring 202 through the throttle valve body 301 and the water inlet pipe 2014, and is located within the inner region of the rubber water squeezing sleeve 204;

[0076] S2. The output shaft of the reduction motor 208 drives the central vertical shaft 205 to rotate, thereby driving the upper and lower two cross angle plates 206 and the four water squeezing rollers 207 to rotate together, roll-press the outer walls of the four rubber water squeezing sleeves 204, so that the water entering the inner region of the rubber water squeezing sleeve 204 quickly passes through the filter holes 203 for filtration and then enters into the region between the pre-treatment tank body 201 and the water retaining station ring 202;

[0077] S3. The purified water after primary filtration inside the pre-treatment tank body 201 is pumped into the interior of the leftmost first filter element 400 through a hose by a primary booster pump 500 for fine filtration, and flows out through the output end of the leftmost first filter element 400, enters into a secondary booster pump 600 located at the left end through a hose. After being pressurized by this secondary booster pump 600, the purified water after primary fine filtration quickly enters into the interior of a filter element 400 located in the middle for re-fine filtration. After flowing out through the output end of this filter element 400 again, it is discharged into the interior of the secondary booster pump 600 located at the right end through a hose. After being pressurized by the secondary booster pump 600 at the right end, the purified water after secondary fine filtration is transported into the interior of the rightmost filter element 400 for final fine filtration to obtain pure water.

[0078] When a pure water purification device of this solution is working, the tops of four water supply pipes 306 are connected to a tap water pipe, and tap water flows into the interiors of four intercepting valve bodies 301 through the four water supply pipes 306. Immediately afterwards, the tap water flows into the interior of a water retaining station ring 202 through a water inlet pipe 2014 and is located in the inner area of four rubber water squeezing sleeves 204. The tap water in the inner area of the rubber water squeezing sleeves 204 is initially filtered through filter holes 203 to remove some large particles and then enters the area between a pre-treatment tank body 201 and the water retaining station ring 202. At the same time, the output shaft of a reduction motor 208 drives a central vertical shaft 205 to rotate. The rotation of the central vertical shaft 205 drives four water squeezing rollers 207 to rotate through the connection of upper and lower cross angle plates 206, and the outer walls of the four rubber water squeezing sleeves 204 are rolled. As a result, the rubber water squeezing sleeves 204 contract, pressurizing the tap water in their inner areas, which can increase the flow rate of the tap water in the water retaining station ring 202 initially filtered through the filter holes 203, thereby improving the filtration efficiency. Moreover, during the process of the water squeezing rollers 207 rolling on the outer walls of the rubber water squeezing sleeves 204 and causing the rubber water squeezing sleeves 204 to contract, due to the elastic support effect of elastic support arc strips 2010 on the inner sides of the rubber water squeezing sleeves 204, the rubber water squeezing sleeves 204 can be prevented from being pushed to one side by the water squeezing rollers 207, ensuring that the rubber water squeezing sleeves 204 always contract towards the direction of the filter holes 203, thereby guaranteeing the pressurizing effect on the tap water. Furthermore, during the process of the rubber water squeezing sleeves 204 contracting towards the filter holes 203, the elastic support arc strips 2010 are affected by the contraction of the rubber water squeezing sleeves 204 and slide along square holes 209, so as not to interfere with the normal contraction of the rubber water squeezing sleeves 204. When the water squeezing rollers 207 roll away from the outer walls of the rubber water squeezing sleeves 204, the elastic support arc strips 2010 recover under the action of their own resilience and slide reversely along the inner walls of the square holes 209 to the initial positions again, jacking up the rubber water squeezing sleeves 204. While providing support for the rubber water squeezing sleeves 204, it can also accelerate the resilience efficiency of the rubber water squeezing sleeves 204;

[0079] During the squeezing roller 207 rolling and pressing the rubber squeezing sleeve 204, the central vertical shaft 205 rotates just to drive the cam 305 to rotate together until the four convex parts contact the ends of the four taper rods 303, so as to push the four taper rods 303 in the direction away from the central vertical shaft 205. The movement of the taper rod 303 drives the plunger 302 to move together, so that the plunger 302 intercepts inside the shut-off valve body 301. At the same time, the spring 304 is stretched and stores energy. And when the plunger 302 intercepts inside the shut-off valve body 301, it causes the inside of the shut-off valve body 301 to be shut off. The tap water flowing into the inside of the shut-off valve body 301 through the water supply pipe 306 cannot continue to drain into the inside of the water inlet pipe 2014, and even less can enter the inside of the water retaining station ring 202. That is to say, during the contraction of the squeezing roller 207 rolling and pressing the rubber squeezing sleeve 204, the device will not continue to supplement tap water into the inside of the rubber squeezing sleeve 204, avoiding the rubber squeezing sleeve 204 from bursting due to excessive load. And when the squeezing roller 207 rolls away from the outer wall of the rubber squeezing sleeve 204, the central vertical shaft 205 just drives the cam 305 to rotate until the four convex parts are misaligned with the ends of the four taper rods 303, ending the thrust on the taper rods 303. The resilience of the spring 304 is released, pushing the taper rods 303 together with the plunger 302 to move in the direction close to the central vertical shaft 205, ending the interception inside the shut-off valve body 301. The tap water can flow smoothly through the inside of the shut-off valve body 301, enter the inside of the water inlet pipe 2014 again, and be continuously drained into the inside of the water retaining station ring 202, and in the area inside the rubber squeezing sleeve 204, repeating the above process to accelerate the primary filtration efficiency of pure water and improve the production capacity of pure water;

[0080] The primary filtered purified water inside the pre-treatment tank body 201 is pumped into the inside of the leftmost first filter element 400 through a hose by the first-stage booster pump 500 for fine filtration, and flows out through the output end of the leftmost first filter element 400, enters into a second-stage booster pump 600 located at the left end through a hose. Through the pressurization of this second-stage booster pump 600, the purified water after the first-stage fine filtration quickly enters into the inside of a filter element 400 located in the middle for re-fine filtration, and after flowing out through the output end of this filter element 400 again, it is drained into the inside of the second-stage booster pump 600 located at the right end through a hose. After being pressurized by the second-stage booster pump 600 at the right end, the purified water after the second-stage fine filtration is transported into the inside of the rightmost filter element 400 for final fine filtration to obtain pure water.

[0081] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
