Description

Technical Field

[0001] The utility model belongs to the technical field of reverse osmosis membrane disassembly tools, and in particular relates to an adjustable tool for disassembling reverse osmosis membranes. Background Art

[0002] In the daily operation of dual-membrane water treatment, the reverse osmosis membrane is installed in the reverse osmosis membrane shell. Due to the lack of handles on the reverse osmosis membrane and the long-term operation under high-pressure water flow, the membrane body becomes compact and difficult to disassemble. This situation makes it difficult and cumbersome to remove the reverse osmosis membrane during regular inspection and maintenance.

[0003] In order to solve this problem, there is currently a dismantling tool with patent number 202022370457.5, which is mainly connected to the threaded hole in the center of the reverse osmosis membrane by connecting screws, and uses a combination of mounting rods and force rods to gradually lift and move the reverse osmosis membrane. Although this tool solves the problem of removing the reverse osmosis membrane to a certain extent, it still has some limitations. For example, the frequent adjustment of the support rod in the through hole makes the operation process complicated. In addition, although rubber pads are used to protect the contact part between the support rod and the reverse osmosis membrane shell, during the force application process, the rigid contact of the support rod may still cause deformation damage to the pipe mouth of the reverse osmosis membrane shell due to the concentration of extrusion stress, thereby affecting the normal operation and service life of the equipment. Therefore, the existing dismantling tools still need to be further improved in terms of practicality and durability. Utility Model Content

[0004] The existing dismantling tools in the background technology still have certain drawbacks in actual use. In the existing dismantling tools, we transform the original rigid contact mode between the support rod and the reverse osmosis membrane shell into a hoop anchoring mode, so that the reverse extrusion stress of the support rod during the original dismantling process is dispersed on the reverse osmosis membrane shell, forming an anchoring force of the hoop on the reverse osmosis membrane shell. At the same time, the support plate is connected to the hoop by two adjusting rods to reduce subsequent frequent adjustment operations. Based on the above-mentioned transformation scheme, the utility model provides an adjustable tool for dismantling reverse osmosis membranes.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adjustable tool for disassembling a reverse osmosis membrane, comprising a support plate and a screw rod arranged in the middle thereof, a handle and a screw head are respectively arranged at the upper and lower ends of the screw rod, the two ends of the support plate are respectively connected to the hoop through an adjusting rod, the adjusting rod comprises a sleeve and a support rod inserted therein, the two support rods are respectively connected to the two ends of the support plate, an adjusting bolt is arranged on each support rod, the support plate is installed on the reverse osmosis membrane shell through the two adjusting rods connecting the hoop, after the screw head is screwed into the central screw hole of the reverse osmosis membrane, the reverse osmosis membrane is lifted out of the reverse osmosis membrane shell and quickly removed by rotating the handle.

[0006] As a further explanation and limitation of the above technical solution, the hoop includes two semicircular hoops hingedly connected to each other, and a hinge screw and a slot connecting seat are respectively provided at the anchoring ends of the two semicircular hoops, and a fastening knob is provided on the hinge screw. The two semicircular hoops are enclosed on the reverse osmosis membrane shell, and the hinge screw is rotated into the slot connecting seat, and the hoop is anchored to the reverse osmosis membrane shell by rotating the fastening knob.

[0007] As a further supplement to the above technical solution, limit seats are respectively arranged on the outer sides of the two semicircular hoops, and the limit seats are used to limit the rotation direction of the sleeve and keep it in a vertical upward state, so as to facilitate the simultaneous insertion of the two support rods into the two sleeves.

[0008] As a further supplementary explanation of the above technical solution, rubber cushion layers are respectively arranged on the outer sides of the two semicircular hoops, and the rubber cushion layers are used to increase the anchoring force and protect the reverse osmosis membrane shell at the same time.

[0009] As a further supplementary explanation of the above technical solution, the lower end of the screw rod is rotatably set on a rotating head, a plug joint is fixed on the rotating head, a slot hole is set on the plug joint, the thread head is fixed on the plug sleeve, and a through hole is set on the plug sleeve. The plug joint is rotated so that the slot hole and the through hole are in the same direction and inserted into the plug sleeve, and bolts pass through the slot hole and the through hole respectively to connect the thread head to the screw rod.

[0010] As a further supplementary explanation of the above technical solution, a side ear is provided on the insert sleeve to facilitate on-site maintenance personnel to screw the thread head into the central screw hole of the reverse osmosis membrane.

[0011] Compared with the existing demolition tools, the utility model has the following advantages:

[0012] 1. The utility model innovatively adopts a hoop anchoring method to firmly install the support plate on the reverse osmosis membrane shell, dispersing the reverse extrusion stress during the disassembly process. This design not only prevents the tool from falling off or sliding during disassembly, thereby improving the safety of operation, but also avoids extrusion damage to the reverse osmosis membrane shell and protects the integrity of the equipment.

[0013] 2. The utility model simplifies the assembly and disassembly process of the tool through the ingenious design of the rotating head and the plug connector. At the same time, this design also enhances the stability of the tool and avoids loosening or falling off during the disassembly process.

[0014] 3. The utility model adopts a combination of a screw rod and a screw head, and cooperates with the rotation of the handle to make the disassembly process of the reverse osmosis membrane faster and more efficient. This design enhances the versatility and adaptability of the tool, improves the reliability and work efficiency of the tool, and has important practical value and broad application prospects.

Embodiment 2

[0024] In order to ensure the reliability of the tool during the removal of the reverse osmosis membrane. Figure 2 and 3 As shown, we add the following two solutions: First, regarding the reason for the insufficient anchoring force of the hoop in the tool, we respectively set a rubber cushion layer 15 on the outer side of the two semicircular hoop rings 501, and the rubber cushion layer 15 is used to increase the anchoring force and protect the reverse osmosis membrane shell 16. Of course, during the disassembly process, we can also fit the support plate 1 with the pipe mouth of the reverse osmosis membrane shell 16 to play a role of leveraging to solve the problem of insufficient anchoring force of the hoop. Second, regarding the effectiveness of the connection between the screw rod and the key component of the thread head in the tool, we rotate the lower end of the screw rod 2 on the rotating head 7, and a plug connector 8 is fixed on the rotating head 7. A slot 9 is set on the plug connector 8. The thread head 4 is fixed on the insert sleeve 10, and a through hole 11 is set on the insert sleeve 10.
