Technical Field

[0001] The invention relates to a reverse osmosis membrane filter, belonging to the technical field of reverse osmosis membrane filters. Background Art

[0002] The reverse osmosis membrane body of the existing reverse osmosis membrane filter is generally cylindrical. The raw water enters the reverse osmosis membrane body radially, and then flows out after being filtered by the reverse osmosis membrane body. During the installation of the existing reverse osmosis membrane filter, one end of the accommodating cavity of the membrane shell is generally opened and then the reverse osmosis membrane body is inserted into the accommodating cavity along the axial direction of the membrane shell, and then one end of the membrane shell is sealed and connected to the external water pipe. A large space is required to install the reverse osmosis membrane body. At the same time, the area required for disassembly and assembly is large, and this installation method is not easy to achieve the positioning or alignment of the reverse osmosis membrane body and the accommodating cavity, and the disassembly and assembly process is troublesome. For example, Chinese patent CN116585893A discloses a detection device for efficiently disassembling and assembling a reverse osmosis membrane. The driving unit is used to make the movable plates at both ends of the reverse osmosis membrane move synchronously, so that the two ends of the reverse osmosis membrane can be quickly connected, but there is a problem of a large required working space.

[0003] At the same time, due to the small gap between the reverse osmosis membrane and the membrane shell, when the reverse osmosis membrane is severely crystallized, the membrane removal operation greatly increases the labor intensity of the maintenance personnel. Moreover, if the operation is improper and excessive force is used during the removal process, it will cause irreversible damage to the reverse osmosis membrane, seriously affecting the normal use of the reverse osmosis device. Summary of the invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides a reverse osmosis membrane filter, which can save the floor space during the disassembly and assembly of the reverse osmosis membrane filter and can also be used to assist in the removal of the reverse osmosis membrane end cover.

[0005] The technical solution of the present invention is as follows:

[0006] A reverse osmosis membrane filter comprises a reverse osmosis membrane body and a reverse osmosis membrane shell, wherein the reverse osmosis membrane shell is composed of a plurality of shell components spliced ​​in sequence, wherein the shell components sequentially comprise a front end, a connecting section and a rear end, wherein the front end is circumferentially evenly provided with a plurality of accommodating cavities, wherein a ball block is movably installed inside the accommodating cavity, and wherein the outer surface of the rear end is circumferentially evenly provided with a plurality of inverted trapezoidal grooves, wherein when adjacent shell components are spliced ​​together by a quick-connect assembly, the accommodating cavities correspond to the grooves, and the ball blocks abut against the surfaces of the grooves.

[0007] Among them, a limit stop ring is circumferentially arranged on the outer wall surface of the shell component, and the limit stop ring is located behind the front side end.

A spring is sleeved inside the annular inward recessed cavity, one side of the spring is fixedly installed on the limit stop ring, and the other side of the spring is fixedly installed on the wall surface of the external shell body close to the limit stop ring.

[0008] Wherein, the outer shell is provided with an air inlet hole through it, and the air inlet hole is used to pump gas into the accommodating cavity.

[0009] Wherein, the outer shell is also provided with an air outlet.

[0010] Among them, the rear side end is provided with a pumping passage through the groove, and the pumping passage is connected to the inside of the reverse osmosis membrane shell; it also includes a sealing plug, which is inserted into the pumping passage and opens the pumping passage after the gas is pumped into it through the air inlet hole.

[0011] Wherein, the interior of the air inlet hole is recessed inward to form a Venturi channel.

[0012] Wherein, the ball bearing block is a hollow structure, and the ball bearing block is hollowed out.

[0013] Wherein, the rear end is provided with an inclined end surface.

[0014] Wherein, the accommodating cavity is funnel-shaped.

[0015] Wherein, the pumping passage includes a main passage and several branch passages, the main passage is connected with the several branch passages, the air inlet end of the main passage is located at the groove, the air outlet end of the branch passage is located inside the reverse osmosis membrane shell, and the sealing plug is arranged at the air inlet end of the main passage, the top of the sealing plug is installed on the groove surface by a hanging rope, and the inner side wall of the pumping passage is provided with an accommodation groove, and the accommodation groove is used to accommodate the sealing plug.

[0016] The present invention has the following beneficial effects:

[0017] The present invention places the reverse osmosis membrane body in the shell component first, and quickly connects the adjacent shell components by plugging and connecting through the cooperation of the quick-connect assembly, so that the reverse osmosis membrane body is located in the complete reverse osmosis membrane shell, and the installation of the reverse osmosis membrane filter is completed; the disassembly process of the reverse osmosis membrane is the reverse operation of the installation process, and the method of splicing or disassembling one by one is adopted, which saves the floor space in the disassembly and assembly process of the reverse osmosis membrane filter; at the same time, it avoids the situation in the prior art that the staff cannot see the position and depth of the reverse osmosis membrane body inserted into the accommodating cavity during the process of pulling and inserting the reverse osmosis membrane body into the accommodating cavity, so as to accurately determine the installation position, thereby improving the accuracy and reliability of the disassembly and assembly of the reverse osmosis membrane filter;

[0018] The present invention also utilizes the vibration caused by the rolling of the ball block to solve the problem that if the operation is improper and too much force is used during the removal process, irreversible damage to the reverse osmosis membrane will be caused;

[0019] At the same time, the present invention utilizes the pumping passage to pump gas, which can increase the air pressure inside the reverse osmosis membrane shell and apply pressure from the inside to the outside. When the staff removes the reverse osmosis membrane end cover from the outside, the removal can be assisted from the inside. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figures 1 to 4, the invention provides a technical solution:

[0028] Embodiment 1:

[0029] like Figure 1 As shown, a reverse osmosis membrane filter comprises a reverse osmosis membrane body 1 and a reverse osmosis membrane shell, wherein the reverse osmosis membrane shell comprises a plurality of shell components 2 which are sequentially spliced ​​together, wherein the shell components 2 sequentially comprise a front side end 21, a connecting section 22 and a rear side end 23, wherein the front side end 21 is circumferentially uniformly provided with a plurality of accommodating cavities 24, wherein a ball block 25 is movably installed inside the accommodating cavity 24, and an outer surface of the rear side end 23 is circumferentially uniformly provided with a plurality of inverted trapezoidal grooves 26, wherein when adjacent shell components 2 are spliced ​​together by a quick-connect assembly, the accommodating cavity 24 corresponds to the groove 26, and the ball block 25 abuts against the surface of the groove 26;

[0030] Specifically, a limit stop ring 3 is circumferentially arranged on the outer wall surface of the shell component 2, and the limit stop ring 3 is located behind the front side end 21. The quick-connect assembly includes an outer shell 4 slidably sleeved on the outer surface of the front side end 21, and an annular inward cavity 41 is arranged on the side of the outer shell 4 close to the limit stop ring 3. A spring 42 is sleeved inside the annular inward cavity 41, and one side of the spring 42 is fixedly installed on the limit stop ring 3, and the other side of the spring 42 is fixedly installed on the wall surface of the outer shell 4 close to the limit stop ring 3; the wall surface of the annular inward cavity 41 is slidably arranged with the outer wall of the limit stop ring 3; under normal conditions, due to the action of the spring 42, the outer shell 4 The housing 4 always covers the top of the accommodating chamber 24, that is, the ball block 25 will not fall out of the accommodating chamber 24. At the same time, the top of the ball block 25 fits with the bottom of the external housing 4, and the bottom part of the ball block 25 is located inside the reverse osmosis membrane housing. Furthermore, a movable groove is provided at the front end of the external housing 4. When the compression spring 42 pushes the external housing 4 toward the limit stop ring 3 to the bottom, at this time, the movable groove is just located above the ball block 25, and the ball block 25 can obtain a certain movable space, that is, the ball block 25 can move up and down in the space composed of the accommodating chamber 24 and the movable groove without falling out;

[0031] When the adjacent shell components 2 are not spliced ​​together, first, the adjacent shell components 2 are brought close to each other, that is, the front side end 21 and the rear side end 23 are close to each other, and at the same time, the outer shell 4 is pushed toward the limit stop ring 3, and the end of the rear side end 23 is provided with an inclined end surface 231. At this time, the inclined end surface 231 will contact the bottom of the ball block 25, which will push the ball block 25 to move toward the movable groove. At this time, there is no obstruction of the ball block 25 inside the reverse osmosis membrane shell, so that the front side end 21 of the shell component 2 can be inserted into the rear side end 23 of the adjacent shell component 2, and then until the accommodating chamber 24 is connected to the groove 26, the spring 42 is released to restore it to normal. At this time, the ball block 25 is located in the space formed by the accommodating chamber 24 and the groove 26, and at the same time, the ball block 25 is abutted against the surface of the groove 26; the docking is completed; docking in this way to form a complete reverse osmosis membrane shell can save floor space during assembly or disassembly;

[0032] As a preferred embodiment, the outer shell 4 is provided with an air inlet 43, and the air inlet 43 is used to pump gas into the accommodating chamber 24. The outer shell 4 is also provided with an air outlet 44. Gas can be input into the air inlet 43 by any method, for example, by integrating all the air inlet 43 into a detachable structure, and then connecting it to an air pump for gas transmission, so that the detachable structure can be put on the reverse osmosis membrane shell and only one interface is detachably connected to the air pump; gas transmission can be achieved; at the same time, a tiny space is reserved inside the accommodating chamber 24 to allow the ball block 25 to rotate; the ball block 25 is a hollow structure, and the ball block 25 is hollowed out; by pumping gas into the air inlet 43, combined with the irregular surface of the ball block 25 The design is that the air flow is pumped in from the air inlet 43 and pumped out from the air outlet 44, which can drive the ball to vibrate irregularly when blowing, causing the internal crystals to fall off through continuous vibration, which is less damaging than the normal crystals falling off through vibration. Specifically, conventionally, other vibration methods need to be set on the outer surface of the reverse osmosis membrane shell for vibration. Since the vibration penetrates a long distance, a larger frequency is required, which can easily damage the internal reverse osmosis membrane. The present structure combined with the reverse osmosis membrane shell of the present device can vibrate at a lower vibration frequency and a closer distance, and can also meet the demand for reducing the occupied space; the air inlet 43 is recessed inward to form a Venturi channel, which can accelerate the pumped gas;

[0033] Embodiment 2:

[0034] The remaining structures are the same as those described above, with the only difference being that the air outlet 44 needs to be sealed when the second embodiment is in use. Specifically, the rear side end 23 is located at the groove 26 and is provided with a pumping passage 27, which is connected to the inside of the reverse osmosis membrane housing; a sealing plug 28 is also included, which is inserted into the pumping passage 27 and opens the pumping passage 27 after the gas is pumped in through the air inlet 43; it is worth mentioning that the pumping passage 27 includes a main passage 271 and a plurality of branch passages 272, the main passage 271 is connected to the plurality of branch passages 272, the air inlet end of the main passage 271 is located at the groove 26, the air outlet end of the branch passage 272 is located inside the reverse osmosis membrane housing, and the sealing plug 28 is provided at the air inlet end of the main passage 271, the top of the sealing plug 28 is installed on the surface of the groove 26 by a hanging rope 29, and the inner side wall of the pumping passage 27 is provided with a placement groove 273, and the placement groove 273 is used to accommodate the sealing plug 28;

[0035] After the operation and vibration of Example 1 are completed, the air outlet 44 is sealed, and then the gas is continuously pumped in, and the gas is continuously accumulated in the space formed by the accommodating chamber 24 and the groove 26. Due to the effect of air pressure, a large amount of gas will squeeze the sealing plug 28, so that the sealing plug 28 slides into the placement groove 273, and then the gas flows into the reverse osmosis membrane shell, so that the air pressure inside the reverse osmosis membrane shell increases, and the crystals adhered between the reverse osmosis membrane shell and the reverse osmosis membrane body 1 can be further broken, and then the air pressure continues to increase, which can assist the staff to push out the reverse osmosis membrane end cover; the method for pushing out the reverse osmosis membrane end cover can refer to the prior art. The device can reduce the labor of the staff by applying force from the inside to assist in pushing out the reverse osmosis membrane end cover through external force.

[0036] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
