Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membrane disassembly and assembly tools, in particular to a reverse osmosis membrane replacement tool. Background Art

[0002] Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The reverse osmosis membrane group in the prior art generally includes a long cylindrical membrane barrel and a reverse osmosis membrane located in the membrane barrel. Both ends of each osmotic membrane have membrane end caps. Usually, there are several reverse osmosis membranes in the membrane barrel. The above reverse osmosis membranes are connected in series through a rod-shaped connector, and the membrane barrel is made of fiberglass or stainless steel.

[0003] The reverse osmosis membrane is installed in the membrane barrel. When the reverse osmosis membrane needs to be cleaned or replaced offline, the reverse osmosis membrane needs to be taken out of the membrane barrel. The reverse osmosis membrane is tightly filled in the membrane barrel. When replacing, a rubber liner needs to be placed on the end of the reverse osmosis membrane at one end of the membrane barrel, and then the membrane is replaced by pushing it forward manually with sleepers. During the replacement process, the inner wall of the membrane barrel is easily damaged, resulting in difficulty in replacement, long maintenance time, high labor intensity in replacement operations, and personal injuries such as bumps and collisions among operators, or accidental damage to the reverse osmosis membrane. Summary of the invention

[0004] The utility model provides a reverse osmosis membrane replacement tool, which overcomes the deficiencies of the above-mentioned prior art and can effectively solve the problems of time-consuming and labor-intensive, low construction efficiency, high labor intensity, high labor cost and potential safety hazards in the existing reverse osmosis membrane replacement operation process, and may also damage the reverse osmosis membrane and cause losses.

[0005] The technical solution of the utility model is achieved through the following measures: a reverse osmosis membrane replacement tool, including a booster screw and a top pressure ring, a rotating part is provided at the right end of the booster screw, a sliding hammer is screwed on the outer side of the left part of the booster screw, a top pressure ring is provided on the left side of the sliding hammer, and at least two support rods are evenly distributed along the circumference between the left side of the top pressure ring and the right side of the sliding hammer.

[0006] The following are further optimizations and / or improvements to the above utility model technical solution:

[0007] The top pressure ring may be evenly distributed along the circumference with a plurality of connecting holes that penetrate left and right.

[0008] The rotating part can be a wrench holder with a drum-shaped, square or hexagonal cross section.

[0009] The above-mentioned top pressure ring can be a rubber-lined top pressure ring.

[0010] The above-mentioned booster screw rod may include a plurality of connecting rod sections which can be detachably mounted together.

[0011] Three support rods may be evenly distributed along the circumference between the right side of the top pressure ring and the left side of the sliding hammer.

[0012] The utility model has a reasonable and compact structure and is easy to use. By rotating the booster screw rod through the rotating part, the reverse osmosis membrane can be easily and quickly pushed through the sliding hammer, the supporting rod and the top pressure ring. The contact area between the rubber-lined top pressure ring and the reverse osmosis membrane is large and has a flexible protective layer, and the force is evenly distributed, which can effectively avoid damage to the reverse osmosis membrane. The disassembly and replacement process saves time and effort, has high operating efficiency, and has low labor intensity for operators.

[0013] Attached Figure 1 It is a schematic diagram of the main view and partial cross-section structure of embodiments 1-6 of the utility model.

[0014] Attached Figure 2 For attachment Figure 1 Schematic diagram of the three-dimensional structure.

[0016] The present invention is not limited by the following embodiments, and specific implementation methods can be determined according to the technical solution of the present invention and actual conditions.

[0017] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached manual. Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0018] The present invention is further described below in conjunction with the embodiments and drawings:

[0019] Embodiment 1: As attached Figure 1 , 2 As shown, the reverse osmosis membrane replacement tool includes a booster screw 1 and a top pressure ring 2. A rotating part is provided at the right end of the booster screw 1. A sliding hammer 3 is screwed on the outer side of the left part of the booster screw 1. A top pressure ring 2 is provided on the left side of the sliding hammer 3. At least two support rods 4 are evenly distributed along the circumference between the left side of the top pressure ring 2 and the right side of the sliding hammer 3.

[0020] During use, when disassembling the reverse osmosis membrane: open the membrane barrel, remove the membrane end cover, place the left end face of the top pressure ring 2 close to the outer end face of the reverse osmosis membrane, and rotate the rotating part, so that the booster screw 1 can push the sliding hammer 3 with force, and the sliding hammer 3 can transfer the thrust through the support rod 4. The top pressure ring 2 pushes the reverse osmosis membrane with force to push the farthest reverse osmosis membrane out of the membrane barrel, and continue to rotate the rotating part to push each reverse osmosis membrane out of the membrane barrel one by one.

[0021] When installing the reverse osmosis membrane: install the first section of the reverse osmosis membrane into the membrane barrel, place the left end face of the top pressure ring 2 close to the outer end face of the reverse osmosis membrane, rotate the rotating part, and push the reverse osmosis membrane to the predetermined position at the far end of the membrane barrel through the booster screw 1, then take out the device, repeat the above actions, and each reverse osmosis membrane can be installed in place one by one.

[0022] According to the requirements, the annular top pressure ring 2 and the support rod 4 can form a space to accommodate the rod-shaped connector on the reverse osmosis membrane, so that the left end face of the top pressure ring 2 can be better close to the end face of the reverse osmosis membrane, effectively increasing the contact area between the end face of the reverse osmosis membrane and the device, so that the thrust generated by the device acts more evenly on the reverse osmosis membrane, rather than on the end face of the rod-shaped connector, to prevent the reverse osmosis membrane from being deflected and damaged during the pushing process. In order to prevent the top pressure ring 2 from scratching the reverse osmosis membrane, a rubber layer can be provided on the left side of the top pressure ring 2, and the top pressure ring 2 can also directly use flexible materials in the prior art, such as rubber or flexible polyurethane. The rotating part can be realized by a rotating wheel, a rod-shaped handle or a trident-shaped handle in the prior art, so that the booster screw 1 can be rotated more easily. In order to reduce the resistance between the device and the inner wall of the membrane barrel and reduce the weight of the device, the outer diameter of the sliding hammer 3 is much smaller than the outer diameter of the top pressure ring 2.

[0023] The utility model has a reasonable and compact structure and is easy to use. By rotating the booster screw 1 through the rotating part, the reverse osmosis membrane can be easily and quickly pushed through the sliding hammer 3, the supporting rod 4 and the top pressure ring 2. The contact area between the top pressure ring 2 and the reverse osmosis membrane is large and the force is evenly distributed, which can effectively avoid damage to the reverse osmosis membrane. The disassembly and replacement process is time-saving and labor-saving, the operation efficiency is high, and the labor intensity of the operators is low. It can be operated by one person, which can effectively reduce the labor cost and avoid safety hazards such as bumps.

[0024] The above reverse osmosis membrane replacement tool can be further optimized and / or improved according to actual needs:

[0025] Embodiment 2: As attached Figure 1 , 2 As shown, the top pressure ring 2 is evenly distributed along the circumference with a plurality of connecting holes 5 that penetrate left and right.

[0026] During use, the device can be fixedly installed together with the reverse osmosis membrane end cover through the connecting hole 5. During disassembly, the proximal reverse osmosis membrane can be pulled out or pulled out from the membrane barrel by reversing the rotating part, so that the reverse osmosis membrane can be disassembled from both ends of the membrane barrel, thereby speeding up the disassembly of the reverse osmosis membrane, saving the physical strength of the operators, and further reducing the labor intensity of the operators.

[0027] Embodiment 3: As attached Figure 1 , 2 As shown, the rotating part is a wrench clamping table 6 with a drum-shaped, square or hexagonal cross section.

[0028] During use, the electric wrench can be clamped on the outside of the wrench clamping platform 6 to rotate the booster screw 1, thereby further reducing the labor intensity of the operators, improving the operating efficiency, and saving time and effort.

[0029] Embodiment 4: The top pressure ring 2 is a rubber-lined top pressure ring 2.

[0030] By such arrangement, the rubber lining can not only provide a soft protective layer at the contact position between the top pressure ring 2 and the reverse osmosis membrane to prevent the top pressure ring 2 from damaging the reverse osmosis membrane, but also enable the top pressure ring 2 to maintain good rigidity, thereby evenly applying the thrust generated by the booster screw 1 to the end face of the reverse osmosis membrane and pushing the reverse osmosis membrane out at a uniform speed.

[0031] Embodiment 5: The booster screw 1 comprises a plurality of connecting rods which are detachably mounted together.

[0032] During use, the length of the replacement tool can be quickly adjusted according to the operating space at the job site, making the device easy and economical to use and not restricted by the site.

[0033] According to requirements, the connecting rod can be composed of multiple sections of sleeves that can be socketed together. In order to prevent the sleeves from rotating relative to each other, a stop structure can be provided between two adjacent sections of the sleeves. It can also be achieved by using multiple sections of connecting rods that can be screwed together, and a stop nail can be provided between the adjacent connecting rods at both ends.

[0034] Embodiment 6: As attached Figure 1 , 2 As shown, three support rods 4 are evenly distributed along the circumference between the right side of the top pressure ring 2 and the left side of the slide hammer 3.

[0035] By such an arrangement, the thrust on the booster screw 1 can be more evenly applied to the reverse osmosis membrane, and the reverse osmosis membrane can be pushed more stably.

[0036] The above technical features constitute the embodiments of the present utility model, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.
