Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of disassembly and assembly of reverse osmosis membrane elements, in particular to a special tool for disassembly and assembly of reverse osmosis membrane elements. Background Art
[0002] The boiler in a captive power station is a high-pressure boiler, fed by desalinated water from a desalination plant. Reverse osmosis equipment is one of the most important water treatment devices in a desalination plant. The reverse osmosis membrane is the core component of a reverse osmosis system, housed in a dedicated membrane housing. Common membrane housings are designed with 1-7 cores, depending on the number of membranes they hold. Large-scale systems typically use a 6-core membrane housing.
[0003] When the reverse osmosis membrane element in the reverse osmosis equipment is replaced or cleaned offline, the reverse osmosis membrane element needs to be removed from the reverse osmosis membrane shell, and a tool for disassembling the reverse osmosis membrane element is needed for disassembly. Since the installation and disassembly of the reverse osmosis membrane element are directional, the traditional disassembly method is to push the membrane assembly forward in the direction of the incoming water flow, so that the membrane assembly in the entire membrane shell is disassembled from the 6th, 5th to the 1st in the order of hammering or using a hook. The force is difficult to control, and such operation makes it very difficult to disassemble the membrane element, which is time-consuming and labor-intensive. Therefore, those skilled in the art provide a special tool for disassembling and assembling a reverse osmosis membrane element to solve the problems raised in the above background technology. Utility Model Content
[0004] (1) Technical problems solved
[0005] In response to the shortcomings of the existing technology, the utility model provides a special tool for disassembling and assembling reverse osmosis membrane elements to solve the problem that traditional reverse osmosis equipment requires disassembly methods such as hammering or using hooks to remove elements, which are difficult to control the force and have a low safety factor. Such operations make disassembling membrane elements very difficult, time-consuming and labor-intensive.
[0006] (2) Technical solution
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special tool for disassembling and assembling reverse osmosis membrane elements, comprising a membrane shell and a membrane core, a threaded hole being provided at the front end of the membrane core, a pull rod being connected in the threaded hole, a protrusion being installed at the other end of the pull rod, a support plate being provided at the front end of the membrane shell, a bolt being installed on the support plate, a pressure plate being rotatably clamped at one end of the bolt, a bracket being installed on one side of the support plate, a screw being rotatably clamped in the bracket, a threaded sleeve being sleeved on the screw, a tilting rod being rotatably connected at one end of the threaded sleeve, a through slot being provided on the tilting rod, and a block being installed on one side of the through slot.
[0008] Preferably, the bolts are threadedly connected to the support plate, and the pressure plate is in compression contact with the outer wall of the membrane shell, thereby fixing the support plate to the end of the membrane shell.
[0009] Preferably, the pull rod passes through the through groove and the through hole in sequence and is threadedly connected to the end of the membrane core. The protrusion is pressed against the block. After the pull rod is connected to the threaded hole at the end of the membrane core, one end of the tilting rod is pulled so that the tilting rod forms a pulling force on the pull rod, and the end of the pull rod with the protrusion contacts the block, so that the pull rod is at the end of the tilt rod close to the threaded sleeve. This time, pulling the tilting rod to drive the pull rod to pull the membrane core outward is more labor-saving and convenient.
[0010] Preferably, the threaded sleeve is threadedly connected to the screw rod, and the threaded sleeve is in contact with the inner wall of the bracket. After the membrane core is pulled a certain distance, the screw rod can be rotated to adjust the position of the threaded sleeve, thereby adjusting the force point of the tilting rod.
[0011] (3) Beneficial effects
[0012] Compared with the prior art, the present invention provides a special tool for disassembling and assembling reverse osmosis membrane elements, which has the following beneficial effects:
[0013] Through design, before disassembling the membrane core in the membrane shell, the support plate is fixed to the end of the membrane shell by bolts and the pressure plate, and then the pull rod is passed through the through groove and the through hole in sequence and connected to the threaded hole at the end of the membrane core. Then the tilting rod is pulled so that the tilting rod forms a pulling force on the pull rod, and the end of the pull rod with the protrusion contacts the block, so that the pull rod is at the end of the tilting rod close to the threaded sleeve. This time, pulling the tilting rod drives the pull rod to pull the membrane core outward, which is more labor-saving and convenient. After the membrane core is pulled a certain distance, the screw can be rotated to adjust the position of the threaded sleeve, thereby adjusting the force point of the tilting rod, which solves the problem that when traditional reverse osmosis equipment removes components, it is difficult to control the force by hitting with a hammer or using a hook, and disassembling the membrane components is very difficult, time-consuming and labor-intensive.
