Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a deep treatment and desalination device for reclaimed water reuse. Background Technology

[0002] Reclaimed water, also known as greywater, refers to wastewater that has been properly treated to meet certain water quality standards and usage requirements. Depending on its quality, treated greywater can be used for various purposes such as urban greening, vehicle washing, fire fighting, and industrial cooling. Compared to traditional long-distance water transfer projects, greywater reuse technology can provide a stable and sustainable local water source, reduce energy consumption, and decrease the demand for wastewater treatment plants and some basic water treatment facilities. Greywater reuse technologies mainly include: physicochemical methods, such as filtration, adsorption, and coagulation sedimentation, but the effluent quality is not high; biological methods, such as activated sludge and biofilm processes, utilize microorganisms to degrade organic pollutants to purify wastewater, but have disadvantages such as difficult operation and maintenance and large land area requirements; and membrane separation methods, which mainly use selectively permeable membrane materials. External pressure is applied to force water through the membrane while pollutants and salts are retained, such as ultrafiltration and reverse osmosis membranes, but the water production rate is not high.

[0003] When desalinizing greywater, water molecules are forced through a reverse osmosis membrane under high external pressure, while salts and organic matter are retained. Over time, a large amount of inorganic scale and organic matter accumulates on the surface and internal pores of the reverse osmosis membrane, requiring the membrane unit to be removed and replaced. During replacement, the membrane unit is often positioned too low in the treatment tank, necessitating a lengthy manual removal process, which increases the replacement time and ultimately reduces the greywater treatment efficiency. This is because backwashing can damage the membrane structure inside the reverse osmosis membrane. Therefore, we propose a greywater reuse deep treatment desalination device. Utility Model Content

[0026] Please see Figures 1-7This utility model provides a technical solution: a deep treatment and desalination device for recycled water, including a treatment tank 1 and a reverse osmosis device body 5. The treatment tank 1 has a placement groove 3 starting from the middle of its upper end. A water outlet mechanism 2 is provided on the lower right side of the treatment tank 1. A reverse osmosis device removal mechanism 4 is provided on the treatment tank 1. The reverse osmosis device removal mechanism 4 includes a bottom limiting component 47, a passing component 48, and a limiting component 49. The passing component 48 is positioned above the limiting component 49, and the limiting component 49 is positioned above the reverse osmosis device. The bottom limiting component 47 of the reverse osmosis device is located on the upper part. The bottom limiting component 47 includes a base plate 471.

[0028] Specifically, the reverse osmosis unit removal mechanism 4 can control the electric push rod 42 via an external synchronizer and external power supply. At this time, the output end of the electric push rod 42 drives the top plate 43 and the cover 44 to move upward. The cover 44 drives the side plate 415 and the moving column 414 to move upward. The moving column 414 moves in the spiral groove 413, thereby driving the contact shaft 412 to rotate. The contact shaft 412 drives the follower shaft 411 and the first rotating rod 410 to rotate.

The outer end of the first rotating rod 410 is threadedly connected to the movable strip 498 and the first rotating rod 410 passes through the movable strip 498.

[0030] Specifically, the reverse osmosis device limiting component 49 allows the reverse osmosis device body 5 to pass through the second through hole 482 and contact the outer end of the clamping arc plate 497. Under the support of the spring force 495, the two clamping arc plates 497 clamp the reverse osmosis device body 5, thereby improving the stability of the reverse osmosis device body 5 during use.

[0031] In this embodiment, a high-pressure pump 45 is fixedly installed on the upper left side of the box cover 44, and an inlet pipe 46 is fixedly connected to the right end of the high-pressure pump 45, with the outer end of the inlet pipe 46 penetrating through the box cover 44.

[0032] Specifically, by introducing greywater from the input end of the high-pressure pump 45, the high-pressure pump 45 directly pumps the greywater into the inlet pipe 46.

[0033] In this embodiment, the inner wall of the processing box 1 is fixedly installed at the outer end of the intermediate plate 481, and the inner wall of the processing box 1 is fixedly installed at the outer end of the bottom plate 471.

[0034] Specifically, ensure that the intermediate plate 481 and the bottom plate 471 do not detach from the processing box 1 during operation.

[0035] In this embodiment, a plurality of circumferentially distributed limiting sleeves 473 are fixedly installed at the lower end of the base plate 471. Each limiting sleeve 473 is provided with a first through hole 472 and a water outlet hole 474 is provided at the lower end of each limiting sleeve 473.

[0036] Specifically, the bottom limiting action of the reverse osmosis unit body 5 can be completed by the limiting sleeve 473.

[0037] In this embodiment, the water outlet mechanism 2 includes a water outlet pipe 21, the outer end of which is fixedly connected to the processing box 1, and a solenoid valve 22 is provided at the outer end of the water outlet pipe 21.

[0038] Specifically, the treated wastewater can be discharged through the water outlet mechanism 2.

[0039] In this embodiment, a sealing plate 417 is fixedly installed at the lower end of the box cover 44, and the outer end of the sealing plate 417 is slidably connected to the placement groove 3.

[0040] Specifically, the sealing plate 417 can be used to seal the placement groove 3.

[0041] In this embodiment, a second limiting circular plate 416 is fixedly installed on the upper end of the contact shaft 412, and a first limiting circular plate 496 is fixedly installed on the outer end of the limiting post 494.

[0042] Specifically, the first limiting circular plate 496 and the second limiting circular plate 416 can limit the upper end of the contact shaft 412 and the outer end of the limiting post 494.

[0043] Working principle: During the desalination of reclaimed water, the external pipe through which the reclaimed water flows can be connected to the input of the high-pressure pump 45. The reclaimed water is then pumped directly into the inlet pipe 46. The reclaimed water passes through the reverse osmosis unit 5 at the upper end of the intermediate plate 481 for treatment. Organic and inorganic substances in the reclaimed water remain on the outside of the membrane inside the reverse osmosis unit 5, while the remaining water flows directly through the lower end of the reverse osmosis unit 5 into the lower space of the bottom plate 471 in the treatment tank 1, and is finally discharged through the outlet mechanism 2. When the reverse osmosis unit 5 needs to be replaced after long-term use, the electric push rod 42 can be controlled via the external synchronizer and external power supply. At this time, the output end of the electric push rod 42 drives the top plate 43 and the box cover 44 to move upward. The box cover 44 drives the side plate 415 and the moving column 414 to move upward. The moving column 414 moves in the spiral groove 413, thereby driving the contact shaft 412 to rotate. The contact shaft 412 drives the follower shaft 411 and the first rotating rod 410 to rotate. The first rotating rod 410 drives the moving bar 498 to move upward. The two symmetrically arranged moving bars 498 drive the moving plate 491 to move upward, thereby driving the reverse osmosis device body 5 to move upward. Through this step, the height adjustment of the reverse osmosis device body 5 can be completed, making it convenient for subsequent maintenance personnel to easily replace the reverse osmosis device body 5.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
