Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis devices, in particular to a reverse osmosis device which is easy to disassemble and clean. Background Art

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. Pressure is applied to the liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent will reversely penetrate in the direction of natural osmosis, thereby obtaining the permeated solvent, i.e., the permeate, on the low-pressure side of the membrane; and a concentrated solution, i.e., the concentrate, on the high-pressure side. If reverse osmosis is used to treat seawater, fresh water will be obtained on the low-pressure side of the membrane, and brine will be obtained on the high-pressure side.

[0003] According to a patent document with announcement number CN220867157U, a reverse osmosis multi-stage filtration device is described, comprising a filter tank, the outer side of which is fixedly connected to a support foot, a connecting pipe connected to the bottom of the filter tank, and a reverse osmosis filter element connected to the bottom of the connecting pipe; a mounting mechanism disposed within the interior of the filter tank, the mounting mechanism comprising a mounting frame disposed within the interior of the filter tank, a filter plate and a fine filter screen plate disposed within the mounting frame, a first limiting groove and a second limiting groove being formed on the inner wall of the mounting frame, a first limiting block being fixedly connected to one side of the filter plate, and a second limiting block being fixedly connected to one side of the fine filter screen plate. The reverse osmosis multi-stage filtration device provided by the utility model solves the problem of some existing reverse osmosis multi-stage filtration devices in which the filter plates are disposed within the filter box and slidably connected to the slide rod, making it inconvenient to disassemble and clean the filter plates, thereby shortening the service life of the filter plates.

[0004] The above patent can effectively extend the service life of the reverse osmosis filter element through the filter screen when in use, and can conveniently disassemble and clean the filter screen. However, during the cleaning process of the filter screen, it is necessary to stop the injection of wastewater, otherwise the reverse osmosis filter element will directly purify the unfiltered wastewater. Based on this, a reverse osmosis device that is easy to disassemble and clean is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0040] The switching mechanism includes:

[0041] A limit rotating frame 2014 is provided inside the housing 1. The limit rotating frame 2014 is located outside the two groups of filter frames 6 and contacts the inner wall of the housing 1. A plurality of limit rings 205 are formed vertically and equidistantly on the outer wall of the limit rotating frame 2014. A limit rotating groove for the plurality of limit rings 205 to rotate is provided at the connection position between the housing 1 and the plurality of limit rings 205.

[0042] In this embodiment, it is particularly noted that a reverse osmosis filter element is installed at the bottom end of the inner wall of the housing 1, and the filtered wastewater can be purified by the reverse osmosis filter element. A drain pipe for discharging the purified wastewater is installed at the bottom end of the housing 1;

[0043] The wastewater to be filtered is fed into the interior of the housing 1 through the water inlet pipe 4. At this time, the first filter screen and the second filter screen on a set of filter frames 6 can be used to perform secondary filtration on the impurities in the wastewater, thereby effectively extending the service life of the reverse osmosis filter element and avoiding frequent replacement and cleaning of the reverse osmosis filter element.

[0044] When it is necessary to clean the filtered debris, the positions of the two groups of filter frames 6 can be swapped through the switching mechanism, and the wastewater can be filtered through the other group of filter frames 6. Then, the bolts are turned to release the fixation of the connecting flap 5, and the connecting flap 5 is flipped over by the hinge. Then, the switching mechanism can be used to conveniently take out and clean one group of filter frames 6;

[0045] When the filter needs to be cleaned, the above operation is reversed and the two cleaned filter frames 6 can be reinstalled inside the housing 1, thereby achieving uninterrupted filtration of wastewater while conveniently cleaning impurities on the filter.

[0046] In one embodiment, Figure 1-Figure 3 As shown, the switching mechanism also includes:

[0047] A driving assembly is provided outside the limit rotating frame 2014, and is used to drive the limit rotating frame 2014 to rotate;

[0048] The drive components include:

[0049] A motor 203 is mounted on the top of the fixed top plate 3. The motor 203 is located above one end of the position-limiting rotating frame 2014. The output end of the motor 203 is fixedly connected to a gear 204. The outer wall of the gear 204 is meshedly connected to a gear ring 201. The gear ring 201 is fixed to the outer wall of the position-limiting rotating frame 2014 and is located inside the housing 1. The housing 1 has an opening at the position where the gear 204 and the gear ring 201 meet, through which the gear 204 and the gear ring 201 rotate.

[0050] The interior of the limit rotating frame 2014 is provided with a moving component, which is used to drive the two groups of filter frames 6 to move up and down respectively;

[0051] In one embodiment, Figure 2-Figure 4 As shown, the mobile components include:

[0052] Two lifting pull frames 207 are symmetrically arranged inside the limit rotating frame 2014.

The lifting pull frames 207 are provided with movable slides for the filter frames 6 to slide, so as to allow the filter frames 6 to move horizontally;

[0053] A connecting component is provided inside the lifting frame 207, and the connecting component is used to drive a group of filter frames 6 to rise through the lifting frame 207;

[0054] In one embodiment, Figure 2-Figure 4 As shown, the connection components include:

[0055] Two connecting rods 2010 are symmetrically fixedly connected to the inner wall of the lifting frame 207. The two connecting rods 2010 are respectively located above the two sides of a group of filter frames 6. The lifting frame 207 can be driven to rise by the connection rods 2010 when pulled by the worker;

[0056] A guide assembly is provided at the top of the lifting frame 207, which is used to limit the movement of the lifting frame 207 and guide the wastewater;

[0057] In one embodiment, Figure 2-Figure 4 As shown, the guide assembly includes a guide frame 209 fixedly connected to the top of the lifting frame 207. The inner wall of the vertical section of the guide frame 209 is inclined and contacts the upper surface of the limit rotating frame 2014 and the inner wall of the housing 1, and is used to block the splashing wastewater and guide the wastewater.

[0058] One end of the lifting pull frame 207 is provided with a clamping assembly, which is used for the insertion and limiting of the two filter frames 6 and the lifting pull frame 207;

[0059] In one embodiment, Figure 3-Figure 5 As shown, the snap-fit assembly includes:

[0060] Two connecting push plates 208 are respectively fixedly connected to one end of the two filter frames 6, and the two connecting push plates 208 are both penetrated into the interior of the lifting pull frame 207. The top ends of the two connecting push plates 208 are integrally formed with a movable sleeve frame 2011, and the movable sleeve frame 2011 penetrates into the interior of the lifting pull frame 207. The inner wall of the movable sleeve frame 2011 is fixedly connected with a rubber ring 2013, and the inner wall of the rubber ring 2013 is sleeved with a fixed block 2012. The end portions of the fixed block 2012 respectively penetrate the outside of the two ends of the movable sleeve frame 2011 and are fixedly connected to the inner wall of the lifting pull frame 207. The rubber ring 2013 can effectively increase the friction between the movable sleeve frame 2011 and the fixed block 2012, thereby effectively preventing the filter frame 6 from sliding and detaching during the lifting process of the lifting pull frame 207.

[0061] A separation component is provided inside the limiting rotating frame 2014, and the separation component is used to separate the two moving components;

[0062] In one embodiment, Figure 3 As shown, the partition assembly includes:

[0063] The second partition plate 206 is fixedly connected to the inside of the limiting rotating frame 2014, and the second partition plate 206 is in contact with the outer wall of the lifting and pulling frame 207. The top of the second partition plate 206 is fixedly connected to the first partition plate 202, and the first partition plate 202 is fixedly connected to the limiting rotating frame 2014 and in contact with the outer wall of the guide frame 209. The two lifting and pulling frames 207 can be separated by the first partition plate 202 and the second partition plate 206, and the guide frame 209 can be supported.

[0064] The above embodiment discloses a reverse osmosis device that is easy to disassemble and clean. In particular, when in use, the present invention feeds wastewater to be filtered into the interior of the housing 1 through the water inlet pipe 4. At this time, the first filter screen and the second filter screen on a set of filter frames 6 can perform a secondary filtration of impurities in the wastewater, thereby effectively extending the service life of the reverse osmosis filter element and avoiding frequent replacement and cleaning of the reverse osmosis filter element. At the same time, the guide frame 209 can block and guide the splashing wastewater.

[0065] When it is necessary to clean the filtered debris, the motor 203 is started to drive the gear 204 to rotate. At the same time, the limit rotating frame 2014 is driven by the gear ring 201 and the engagement of the gear 204, and rotates along the inner wall of the shell 1 through multiple limit rings 205. At this time, the first partition plate 202 and the second partition plate 206 are rotated under the drive of the limit rotating frame 2014. At the same time, the two lifting pull frames 207 are driven by the guide frame 209 under the drive of the limit rotating frame 2014, the first partition plate 202, and the second partition plate 206. In this way, the positions of the two lifting pull frames 207 can be swapped, so that the wastewater can be filtered through another set of filter frames 6;

[0066] After that, the bolt is turned to release the connection flap 5, and the connection flap 5 is flipped over by the hinge, and then the connection rod 2010 is pulled to drive the lifting frame 207 to rise. During this process, a group of filter frames 6 are lifted up by the lifting frame 207, so that a group of filter frames 6 can be easily taken out. Then, the bolt is turned to fix the connection flap 5 again, and the filtered wastewater can be purified by the reverse osmosis filter element.

[0067] Then, the two connecting push plates 208 are pulled to respectively remove the two filter frames 6 from the interior of the lifting pull frame 207. At the same time, the movable sleeve frame 2011 is driven by the connecting push plates 208 to drive the rubber ring 2013 and the fixed block 2012 to separate from each other. At this time, the rubber ring 2013 recovers through its own elasticity, and then the two filter frames 6 can be cleaned conveniently.

[0068] When the filter needs to be cleaned, the above operation is reversed and the two cleaned filter frames 6 can be reinstalled inside the housing 1, so that impurities on the filter can be conveniently cleaned while the wastewater is continuously filtered.

[0069] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
