Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis device cleaning technology, specifically a reverse osmosis self-cleaning reflux device. Background Technology

[0002] Reverse osmosis devices are mainly used to convert high-concentration water into low-concentration water, while isolating all impurities such as industrial pollutants, heavy metals, bacteria, and viruses mixed in with the water, thereby meeting the physicochemical indicators and hygiene standards stipulated for drinking water. However, after the reverse osmosis device is used, a lot of impurities will remain inside it, which will affect the subsequent production of purified water. Therefore, the reverse osmosis device needs to be self-cleaned after each use.

[0003] Existing automatic cleaning devices for reverse osmosis systems mostly use external pipes installed inside the reverse osmosis unit to allow the cleaning solution to flow back. However, this method requires frequent disassembly and reassembly of the external pipes, making the cleaning process after each use of the reverse osmosis unit not timely enough. At the same time, most existing cleaning methods involve adding cleaning solution inside for circulation cleaning, and using water flow to carry out internal impurities. However, the cleaning process is lengthy and inconvenient for users. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a reverse osmosis self-cleaning reflux device, which has the advantages of timely cleaning, fast cleaning speed, and high cleaning efficiency, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a reverse osmosis self-cleaning reflux device, including a reverse osmosis tank, a plurality of observation plates fixedly installed on the upper end face of the reverse osmosis tank, a reflux cleaning mechanism fixedly installed on the outside of the reverse osmosis tank, a plurality of fixing components fixedly installed between the reflux cleaning mechanism and the reverse osmosis tank, a connecting block fixedly installed on one side of the reverse osmosis tank, a water pump fixedly installed on the lower end face of the connecting block, and two support mechanisms fixedly installed on the lower end face of the reverse osmosis tank.

[0006] As a preferred technical solution of this utility model, a No. 1 liquid inlet pipe is fixedly installed on the upper end face of the reverse osmosis tank, and a sealing plug is snapped into the upper end face of the No. 1 liquid inlet pipe.

[0007] As a preferred technical solution of this utility model, a No. 1 liquid outlet pipe is fixedly installed on the lower end face of the reflux cleaning mechanism, and a No. 1 valve is fixedly installed on the outside of the No. 1 liquid outlet pipe.

[0008] As a preferred technical solution of this utility model, the reflux cleaning mechanism includes a second inlet pipe, a second valve is fixedly installed on the outside of the second inlet pipe, and a reflux connection pipe is fixedly installed on one side of the second inlet pipe.

[0009] As a preferred embodiment of this utility model, a second liquid outlet pipe is fixedly installed on the upper end face of the return connection pipe, and a high-pressure nozzle is fixedly installed at the outlet of the second liquid outlet pipe.

[0010] As a preferred embodiment of this utility model, the support mechanism includes a connecting plate, two support rods are fixedly installed on the upper surface of the connecting plate, and a fixing bolt is threaded onto the upper surface of the connecting plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This reverse osmosis self-cleaning reflux device directly installs the reflux cleaning mechanism on the outside of the reverse osmosis tank and controls the switch through valve No. 2. When the reverse osmosis device needs to be cleaned, simply close valve No. 1, open valve No. 2, and add cleaning fluid to clean the inside of the reverse osmosis tank. There is no need to frequently install external pipes, saving time and effort.

[0013] 2. This reverse osmosis self-cleaning reflux device uses a connecting block installed on the outside of the reverse osmosis tank to mount the water pump on the outside of the No. 2 inlet pipe. A high-pressure nozzle is installed at the outlet of the No. 2 outlet pipe. When cleaning the reverse osmosis device, valve No. 1 is closed and valve No. 2 is opened. The water pump then draws and pressurizes the cleaning solution, which is then sprayed out by the high-pressure nozzle. This can flush some stubborn impurities inside the reverse osmosis tank off the reverse osmosis membrane, allowing them to fully contact and react with the cleaning solution, thus increasing the cleaning effect. The water pump then repeats the drawing and pressurization process until the reverse osmosis device is cleaned. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 The reverse osmosis self-cleaning reflux device includes a reverse osmosis tank 1, multiple observation plates 2 are fixedly installed on the upper surface of the reverse osmosis tank 1, a reflux cleaning mechanism 6 is fixedly installed on the outside of the reverse osmosis tank 1, multiple fixing components 5 are fixedly installed between the reflux cleaning mechanism 6 and the reverse osmosis tank 1, a connecting block 7 is fixedly installed on one side of the reverse osmosis tank 1, a water pump 8 is fixedly installed on the lower surface of the connecting block 7, two support mechanisms 9 are fixedly installed on the lower surface of the reverse osmosis tank 1, a first inlet pipe 3 is fixedly installed on the upper surface of the reverse osmosis tank 1, a sealing plug 4 is snapped into the upper surface of the first inlet pipe 3, a first outlet pipe 10 is fixedly installed on the lower surface of the reflux cleaning mechanism 6, and a first valve 11 is fixedly installed on the outside of the first outlet pipe 10.

[0022] In the above structure, by installing an observation plate 2 on the upper end of the reverse osmosis tank 1, the staff can easily observe the accumulation of impurities inside the reverse osmosis tank 1 through the observation plate 2, which facilitates timely cleaning of the reverse osmosis device. Wastewater or cleaning solution can be added into the reverse osmosis tank 1 through the No. 1 inlet pipe 3. The sealing plug 4 can prevent large impurities from entering the reverse osmosis tank 1 through the No. 1 inlet pipe 3 during the cleaning of the reverse osmosis device, thus affecting the cleaning effect. The No. 1 valve 11 can control the opening and closing of the No. 1 outlet pipe 10. The connecting block 7 on the outside of the reverse osmosis tank 1 is used to install and fix the water pump 8 on the outside of the reflux cleaning mechanism 6. The fixing component 5 is used to fix the reflux cleaning mechanism 6 on the outside of the reverse osmosis tank 1 to prevent the reflux cleaning mechanism 6 from shaking during the reflux cleaning process, which would affect the cleaning effect.

[0023] In a preferred embodiment, the reflux cleaning mechanism 6 includes a second inlet pipe 603, a second valve 602 fixedly installed on the outside of the second inlet pipe 603, a reflux connecting pipe 601 fixedly installed on one side of the second inlet pipe 603, a second outlet pipe 605 fixedly installed on the upper end face of the reflux connecting pipe 601, and a high-pressure nozzle 604 fixedly installed at the outlet of the second outlet pipe 605.

[0024] In the above structure, after the cleaning solution enters the reverse osmosis tank 1, it undergoes one round of cleaning and then enters the reflux cleaning mechanism 6 through the second inlet pipe 603. Subsequently, it is pressurized by the water pump 8 and sprayed out through the reflux connection pipe 601 and the second outlet pipe 605 by the high-pressure nozzle 604. The impact force washes some impurities off the reverse osmosis membrane, allowing the impurities to fully contact the cleaning solution, thus accelerating the cleaning speed and increasing the cleaning efficiency.

[0025] In a preferred embodiment, the support mechanism 9 includes a connecting plate 902, two support rods 901 are fixedly installed on the upper end face of the connecting plate 902, and a fixing bolt 903 is threaded onto the upper end face of the connecting plate 902.

[0026] In the above structure, the reverse osmosis tank 1 and the connecting plate 902 are connected by the support rod 901 to support the reverse osmosis device. Then, the reverse osmosis device is fixed to the ground by the fixing bolts 903, which reduces the shaking of the reverse osmosis device during operation and increases the service life of the reverse osmosis device.

[0027] Working principle: When the reverse osmosis unit needs cleaning, first close valve 11 and open valve 602. Then, add cleaning solution into the reverse osmosis tank 1 through inlet pipe 3. After one round of cleaning, turn on water pump 8 to extract the cleaning solution from the reverse osmosis tank 1 through the reflux cleaning mechanism 6 and spray it out through high-pressure nozzle 604, thereby flushing some stubborn impurities off the reverse osmosis membrane and allowing these impurities to fully contact and dissolve with the cleaning solution, thus increasing the cleaning effect of the cleaning solution. Then, the water pump 8 is used to repeatedly extract and clean the reverse osmosis tank 1. After the reverse osmosis tank 1 is completely cleaned, simply open valve 11 to discharge the cleaning waste liquid from outlet pipe 10. Then, simply close valve 602 to restart the water purification process.

[0028] 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.
