Description

Technical Field

[0001] The utility model belongs to the technical field of reverse osmosis membranes and relates to a reverse osmosis membrane removal device. Background Art

[0002] Reverse osmosis is the most sophisticated membrane-based liquid separation technology, separating the solvent from the solutes within it within the ionic range. It blocks almost all soluble salts, allowing only the water solvent to pass through, and can remove the vast majority of suspended solids, colloids, organic matter, and salts from water. During operation, the reverse osmosis membrane is inevitably contaminated or blocked by trace amounts of inorganic matter, colloids, microorganisms, metal oxides, etc. These substances deposit on the membrane surface and accumulate, causing a decrease in membrane permeability or a reduction in salt rejection. Therefore, in order to restore the membrane's permeability and salt rejection performance, the reverse osmosis membrane needs to be cleaned and replaced regularly.

[0003] In the prior art, a reverse osmosis membrane shell is used to install and fix the reverse osmosis membrane. However, when the reverse osmosis membrane is removed, replaced or maintained, it is difficult to remove the reverse osmosis membrane from the reverse osmosis membrane shell. The removal of the reverse osmosis membrane takes a long time, resulting in low efficiency in removing or replacing the reverse osmosis membrane. In order to solve the technical problems mentioned above, the present invention proposes a reverse osmosis membrane removal device. Utility Model Content

[0006] A reverse osmosis membrane removal device includes a fixing frame, one end of the fixing frame is provided with a fixing assembly for fixing the device, the other end of the fixing frame is provided with a traction assembly, a steel wire rope is provided on the inner side of the fixing frame, one end of the steel wire rope is connected to the traction assembly, the traction assembly is used to reel in the steel wire rope, and the end of the steel wire rope away from the traction assembly is provided with a dragging assembly for pulling the reverse osmosis membrane; the dragging assembly includes a screw, the screw is fixed to the end of the steel wire rope away from the traction assembly, the outer side of the screw is provided with a push plate, the outer side of the screw is also threadedly connected to a limiting nut, and the push plate is located at the end of the screw close to the traction assembly.

[0007] Furthermore, it also includes a guide component, which is arranged on the inner side of the fixing frame. The guide component can slide along the length direction of the fixing frame. The guide component is located between the dragging component and the traction component, and the wire rope passes through the middle of the guide component.

[0008] Specifically, a guide ring is fixedly connected to the middle part of the guide assembly, the wire rope passes through the inner side of the guide ring, the upper and lower ends of the fixing frame are provided with sliding grooves along the length direction, the upper and lower ends of the guide assembly are slidably connected to the fixing frame through the sliding grooves, and fixing bolts are threadedly connected at both sides of the guide assembly and at positions corresponding to the guide ring, and the ends of the fixing bolts extend to the inner side of the guide ring.

[0009] Specifically, the upper and lower ends of the guide assembly are both threadedly connected with gripping bolts.

[0010] Furthermore, the fixing assembly includes a splint, which is located at a position inside the fixing frame. There are multiple splints, and the multiple splints are arranged in a circular array. Adjustment bolts are threadedly connected at positions outside the fixing frame and corresponding to the splints, and the adjustment bolts are rotatably connected to the splints at the corresponding positions.

[0013] 1. The utility model adopts the structural coordination design of the fixing frame, the fixing assembly, the traction assembly, the steel wire rope and the dragging assembly, so that the device can be fixed to the reverse osmosis membrane shell through the fixing assembly. After the steel wire rope is passed from one end of the reverse osmosis membrane to the other end, the dragging assembly is installed to the end of the steel wire rope. When the steel wire rope is pulled by the traction assembly, the dragging assembly presses against the reverse osmosis membrane and moves in the direction of the traction assembly, so that the reverse osmosis membrane can be removed from the reverse osmosis membrane shell.

[0024] like Figure 1-4 As shown, a reverse osmosis membrane removal device includes a fixing frame 1, a fixing component 2 is provided at one end of the fixing frame 1 for fixing the device, a traction component 3 is provided at the other end of the fixing frame 1, a steel wire rope 4 is provided on the inner side of the fixing frame 1, one end of the steel wire rope 4 is connected to the traction component 3, the traction component 3 is used for winding the steel wire rope 4, and a dragging component 5 is provided at the end of the steel wire rope 4 away from the traction component 3 for pulling the reverse osmosis membrane; specifically, the dragging component 5 includes a screw rod 8, the screw rod 8 is fixed to the end of the steel wire rope 4 away from the traction component 3, a push plate 9 is provided on the outer side of the screw rod 8, and a limiting nut 10 is also threadedly connected to the outer side of the screw rod 8, and the push plate 9 is located at the end of the screw rod 8 close to the traction component 3.

[0025] When the utility model is in use, the fixing frame 1 is fixed to the end of the reverse osmosis membrane shell by the fixing component 2, the push plate 9 and the limit nut 10 are removed from the screw rod 8, and then the screw rod 8 carrying the wire rope 4 is passed through the middle of the reverse osmosis membrane until it extends out from the other end, and then the push plate 9 is sleeved on the outside of the screw rod 8, and the limit nut 10 is installed to limit the movement of the push plate 9, and then the traction component 3 is started to reel in one end of the wire rope 4, so that the reverse osmosis membrane is dragged out of the reverse osmosis membrane shell by the dragging component 5 at the other end of the wire rope 4.

[0026] like Figure 5 As shown, the present invention also includes a guide assembly 6, which is arranged on the inner side of the fixed frame 1. The guide assembly 6 can slide along the length direction of the fixed frame 1. The guide assembly 6 is located between the dragging assembly 5 and the traction assembly 3, and the wire rope 4 passes through the middle of the guide assembly 6.

[0027] In order to facilitate dragging of the wire rope 4, a guide ring 11 is fixedly connected to the middle part of the guide assembly 6, and the wire rope 4 passes through the inside of the guide ring 11. The upper and lower ends of the fixing frame 1 are provided with sliding grooves 7 along the length direction. The upper and lower ends of the guide assembly 6 are slidingly connected to the fixing frame 1 through the sliding grooves 7. Fixing bolts 12 are threadedly connected at positions corresponding to the guide ring 11 on both sides of the guide assembly 6.

[0033] The utility model starts the driving motor 19 to drive the driving gear 20 to rotate, and the driving gear 20 is meshed with the driven gear 18, so that when the driving gear 20 rotates, the shell drives the winding roller 17 to rotate, thereby driving the winding of the wire rope 4 through the winding roller 17 shell, and then the reverse osmosis membrane can be dragged by the movement of the wire rope 4 and the dragging component 5.
