Description

Technical Field

[0001] This invention relates to the field of separation technology, specifically to an ultrafiltration device for water preparation based on an environmentally friendly and healthy all-membrane method. Background Technology

[0002] Ultrafiltration has a wide range of applications. It can remove impurities such as suspended solids, colloids, color, turbidity, organic matter, bacteria, and E. coli. With the development of membrane manufacturing technology, the uses of ultrafiltration are becoming more and more widespread. Currently, ultrafiltration membrane technology is used in seawater desalination, reclaimed water reuse, pretreatment of reverse osmosis systems, condensate treatment, and ultrapure water preparation. Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. Compared with conventional pretreatment, ultrafiltration technology has advantages such as standardized design, low investment, wide application range, high output, no need for continuous chemical addition, high stability, low labor requirements, small footprint, high degree of automation, and convenient operation.

[0003] The whole membrane water treatment process mainly combines different membrane technologies. It uses conventional water sources or municipal sewage and industrial wastewater that have been treated by biochemistry, filtration and other conventional methods to meet discharge standards as influent. It adopts a combination of ultrafiltration, reverse osmosis and EDI processes to achieve the purpose of efficient removal of pollutants and deep desalination, so as to meet the water quality requirements of various applications.

[0004] Existing all-membrane ultrafiltration technology still has some shortcomings. Since the ultrafiltration membrane is in direct contact with wastewater, some pollutants often adhere to the membrane surface, resulting in two situations: pollutants remain and adhere to the membrane surface and block the membrane pores. When the hardness, alkalinity, and sulfate ion concentration in the water are high, scaling will occur on the membrane surface, which is not conducive to the requirements of various water quality applications and is difficult to meet people's daily needs.

[0016] This invention provides an ultrafiltration device for water preparation based on an environmentally friendly and healthy all-membrane method. It has the following beneficial effects:

[0017] (i) The ultrafiltration device for water preparation based on the environmentally friendly and healthy all-membrane method enters the inner cavity of the metal outer cavity through the water injection pipe and the lower pipe, and impacts the separation device to a certain extent, so that the equipment has a certain driving effect and the basic effect of ultrafiltration.

[0018] (II) This environmentally friendly and healthy all-membrane water preparation ultrafiltration device uses wastewater to impact the membrane protection device, causing the main shaft to twist. The main shaft is linked to the membrane protection device for synchronous operation, and the membrane protection device drives the vertical strips to move synchronously. The membrane protection device provides a certain degree of stable support. The rotation of the vertical strips gradually links with the wiping component to clean the interior.

[0019] (III) This ultrafiltration device for water preparation based on the environmentally friendly and healthy all-membrane method gradually moves in a circular motion with the column and the linkage transmission component. The rotation of the transmission component and the collision between the inside of the push block are mutually generated. The transmission component transmits force to the push block. The deflection angle at the bottom of the transmission component squeezes the push block to move inward. The push block pushes the protective membrane on the outer surface to move.

[0020] (iv) The ultrafiltration device for water preparation based on environmental protection and health uses an all-membrane method to perform ultrafiltration on wastewater. The pusher and the agitator interact, causing the agitator to move towards the limiting frame seat. The agitator inserts into the interior of the limiting frame seat, which gradually pushes the descaling plate to operate. The descaling plate gradually removes the adhering wastewater that falls onto the upper surface of the ultrafiltration device, ensuring that the upper surface is clean and hygienic.

[0021] (V) This environmentally friendly and healthy all-membrane water preparation ultrafiltration device will deflect when the ultrafiltration device is rubbed. The ultrafiltration device will deflect synchronously with the metal support rod. The metal support rod will swing the wound buffer coil outward. The buffer coil will twist to a certain extent. The buffer coil will squeeze the mounting piece outward. The mounting piece will drive the unblocking strip to move. The unblocking strip will thus unblock the inner hole of the ultrafiltration device, ensuring that there is no sticking inside, achieving a certain processing effect, and completing the purification effect smoothly.

The lower surface of the water injection pipe 4 is provided with the separation device 5, and the lower surface of the water injection pipe 4 is fixedly connected to the outer surface of the separation device 5.

[0039] The main shaft 51 and the membrane protection device 52 are placed perpendicular to each other, and the width of the main shaft 51 is greater than the width of the membrane protection device 52. The membrane protection device 52 drives the vertical strip 53 to move synchronously. The membrane protection device 52 plays a certain role in stabilizing and supporting. A wiping element 54 is provided on the lower surface of the membrane protection device 52, and the lower surface of the membrane protection device 52 is fixedly connected to the upper surface of the wiping element 54.

[0040] The membrane protection device 52 also includes an installation component 521. The top of the installation component 521 is provided with a column 522, and the top of the installation component 521 is movably connected to the lower surface of the column 522. The column 522 gradually moves in a circular motion with the linkage transmission component 525. The transmission component 525 rotates and collides with the interior of the push block 526.

The outer side of the transmission component 525 is provided with a push block 526, and the outer side of the transmission component 525 is movably connected to the inner surface of the push block 526.

[0041] The height of the arc guide 523 is lower than the height of the mounting assembly 521. The arc guide 523 moves in conjunction with the column 522. The guide rail 524 can move better along the groove on the outer surface of the metal outer cavity 1. The center lines of the arc guide 523 and the mounting assembly 521 are on the same straight line. The column 522 and the mounting assembly 521 are perpendicular to each other.

[0042] The diameter of the transmission component 525 is smaller than that of the column 522. The transmission component 525 transmits force to the push block 526. The deflection angle at the bottom of the transmission component 525 squeezes the push block 526 to move inward. The push block 526 pushes the protective membrane on the outer surface to move. The protective membrane and the wastewater inside treat each other. Both the transmission component 525 and the column 522 are made of stainless steel. A pad is provided between the transmission component 525 and the column 522.

[0043] The ultrafiltration device 55 also includes a core disk 551. The upper surface of the core disk 551 is provided with a toggle bar 552. When the toggle bar 552 moves, it moves towards the limiting frame 553 and penetrates into the interior of the limiting frame 553. The upper surface of the core disk 551 is movably connected to the lower surface of the toggle bar 552. The lower surface of the toggle bar 552 is provided with the limiting frame 553, and the outer surface of the toggle bar 552 is movably connected to the inner surface of the limiting frame 553. The inner surface of the limiting frame 553 is provided with a descaling plate 554, and the inner surface of the limiting frame 553 is movably connected to the outer surface of the descaling plate 554.

[0044] The descaling plate 554 contacts the limiting frame 553, the actuating bar 552 penetrates into the interior of the limiting frame 553, and the limiting frame 553 gradually pushes the descaling plate 554 to run. The outer side of the descaling plate 554 is matched with the inner groove of the limiting frame 553, and the center lines of the descaling plate 554 and the limiting frame 553 are on the same straight line.

[0045] The anti-blocking device 6 includes a metal support rod 61, which swings the wound buffer coil 62 outward, causing the buffer coil 62 to twist to a certain extent. The outer surface of the metal support rod 61 is provided with the buffer coil 62, and the outer surface of the metal support rod 61 is movably connected to the inner surface of the buffer coil 62. The outer surface of the buffer coil 62 is provided with a mounting member 63, and the outer surface of the buffer coil 62 is slidably connected to the inner surface of the mounting member 63. The top end of the mounting member 63 is provided with a clearing strip 64, and the top end of the mounting member 63 is fixedly connected to the bottom end of the clearing strip 64.

[0046] When using the device, first check the installation, fixation, and safety protection of the device. Place the wastewater to be purified inside the water injection pipe 4. The water injection pipe 4 enters the inner cavity of the metal outer cavity 1 through the pipe below and impacts the separation device 5 to a certain extent, thereby giving the device a certain driving effect and the basic effect of ultrafiltration.

[0047] When the wastewater impacts the membrane protection device 52, the main shaft 51 undergoes a certain torsional action. The main shaft 51 is linked to the membrane protection device 52 for synchronous operation. The membrane protection device 52 drives the vertical strips 53 to move synchronously. The membrane protection device 52 provides a certain degree of stable support. As the vertical strips 53 rotate, they gradually link with the wiping component 54 to clean the interior. The wiping component 54 treats the sludge and other impurities inside, thereby ensuring that the sludge inside can be basically cleaned and playing a certain auxiliary cleaning effect.

[0048] When the vertical bar 53 rotates, it will collide with the arc guide 523. The arc guide 523 moves due to the collision, and the arc guide 523 moves in conjunction with the column 522. The guide rail 524 facilitates better movement along the groove on the outer surface of the metal outer cavity 1. The column 522 gradually moves in a circle with the linkage transmission component 525. The transmission component 525 rotates and collides with the inside of the push block 526. The transmission component 525 transmits force to the push block 526. The deflection angle at the bottom of the transmission component 525 squeezes the push block 526 to move inward. The push block 526 pushes the protective membrane on the outer surface to move. The protective membrane treats the wastewater inside, avoiding reverse osmosis and ensuring that the wastewater inside can be treated again, thus increasing the cleaning effect.

[0049] The pusher block 526 will gradually interact with the ultrafiltration device 55, which performs ultrafiltration on the wastewater. The pusher block 526 interacts with the actuating bar 552, causing the actuating bar 552 to move towards the limiting frame 553. The actuating bar 552 penetrates into the interior of the limiting frame 553, and the limiting frame 553 gradually pushes the descaling plate 554 to operate. The descaling plate 554 gradually removes the adhering wastewater that falls onto the upper surface of the ultrafiltration device 55, ensuring that the upper surface is clean and hygienic.

[0050] A metal support rod 61 is provided at the bottom of the ultrafiltration device 55. When the ultrafiltration device 55 is rubbed, it will deflect. The ultrafiltration device 55 and the metal support rod 61 deflect synchronously. The metal support rod 61 throws the wound buffer winding 62 outward. The buffer winding 62 undergoes a certain twist. The buffer winding 62 squeezes the mounting piece 63 outward. The mounting piece 63 drives the unblocking strip 64 to move. The unblocking strip 64 thus unblocks the inner hole of the ultrafiltration device 55, ensuring that there is no sticking inside, achieving a certain processing effect, and completing the purification effect smoothly.
