Abstract

The utility model provides a disassembling tool, which comprises a screw rod, a fixed ring and a grabbing hook, wherein the fixed ring comprises an inner ring and an outer ring which are connected, the inner side of the inner ring is provided with a thread, the inner ring is spirally sheathed on the screw rod, the grabbing hook is sheathed on one end of the screw rod and can rotate around the screw rod, and the two ends of the screw rod are respectively fixed with a nut. The disassembling tool for a reverse osmosis membrane modulus is used, so that the time for disassembling the reverse osmosis membrane modulus can be greatly saved, under the help of the disassembling tool, disassembling the reverse osmosis membrane modulus is more energy-saving, the disassembling can be carried out from the water inlet end or the water generating end of the reverse osmosis membrane modulus, and the damage to the membrane end surface and the membrane shell of a membrane element during the disassembling can be effectively avoided.

Description

A kind of extracting tool

Technical field

The utility model relates to the machine tool field, particularly a kind of extracting tool.

Background technology

Counter-infiltration is a high-new membrane separation technique, and its aperture, reverse osmosis membrane aperture is little of nanoscale, mostly≤10 * 10 ^-10(10A), under certain pressure, hydrone can pass through the film surface, and impurity such as inorganic salts, heavy metal ion, organic matter, colloid, bacterium, virus can't pass through, thereby reaches the removal purpose.Reverse osmosis technology occupies critical positions with its novel, efficient, energy-conservation isolation technics at water and fluid separation applications territory, is used widely in a plurality of fields such as desalinization, middle water reuse, micro-polluted surface water treatments at present.

Please referring to Fig. 1, Fig. 1 is the structural representation of the reverse osmosis membrane group of prior art.As shown in Figure 1, the reverse osmosis membrane group of prior art comprises putamina 101, is positioned at membrane component 102 compositions of putamina, the two ends of each membrane component 102 all have film end cap 103, usually the membrane component 102 in the putamina is a plurality of, be installed in series by the connector connection, putamina 101 is made for fiberglass or stainless steel material.Please referring to Fig. 2, Fig. 2 is the structural representation of film end cap on the membrane component.

When maintenance reverse osmosis membrane group, because the reverse osmosis membrane group is directive (water inlet end and product water end (W.E.)), in each reverse osmosis membrane group a plurality of membrane components are housed successively, film end cap on each membrane component is with having hook-shaped sealing ring between the film, usually need reach along the installation direction of hook-shaped sealing ring when from putamina, taking out membrane component by hand, otherwise be difficult to take out membrane component.Normally the product water end (W.E.) from the reverse osmosis membrane group takes out membrane component, when needs take out the membrane component of the most close water inlet end, need to take out successively near the membrane component that produces water end (W.E.) from producing water end (W.E.), the last membrane component of water inlet end that will lean on again takes out, so and the film end cap of membrane component causes the damage of film end face and putamina easily because require great effort very much when not having special handle to take out.

The utility model content

The technical problems to be solved in the utility model provides a kind of extracting tool, to solve relatively difficulty and easily cause the problem of reverse osmosis membrane group damage in unloading process of hand disassembly reverse osmosis membrane group in the prior art.

For solving the problems of the technologies described above, the utility model provides a kind of extracting tool, comprise screw rod, retainer plate and grab and collude, described retainer plate comprises inner ring and outer ring, described inner ring is connected with described outer ring, and the inboard of described inner ring has screw thread, and described inner ring screw-casing is located on the described screw rod, described grabbing colluded an end that is placed in described screw rod and can be centered on described screw rod rotation, and the two ends of described screw rod all are fixed with nut.

Optionally, described screw rod, retainer plate and grab to collude and all adopt steel matter to make.

Optionally, described grab to collude have at least two and collude and grab.

Use extracting tool of the present utility model can save the time of dismounting reverse osmosis membrane group greatly, because it is more laborsaving when under the help of extracting tool, dismantling the reverse osmosis membrane group, therefore no matter, and can effectively avoid unloading process to the film end face of membrane component and the damage of putamina from the water inlet end of reverse osmosis membrane group or produce water end (W.E.) and all can dismantle.

Fig. 2 is the structural representation of film end cap on the membrane component;

Figure 3 shows that the structural representation of extracting tool of the present utility model.

The specific embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.

Extracting tool of the present utility model can be widely used in multiple field; and can utilize multiple substitute mode to realize; be to be illustrated below by preferred embodiment; certainly the utility model is not limited to this specific embodiment, and the known general replacement of one of ordinary skilled in the art is encompassed in the protection domain of the present utility model far and away.

Secondly, the utility model utilizes schematic diagram to describe in detail, and when the utility model embodiment was described in detail in detail, for convenience of explanation, schematic diagram disobeyed that general ratio is local amplifies, should be with this as to qualification of the present utility model.

Please referring to Fig. 3, Figure 3 shows that the structural representation of extracting tool of the present utility model, as shown in Figure 3, extracting tool of the present utility model comprises screw rod 210, retainer plate 220 and grabs and collude 230, described retainer plate 220 comprises inner ring 221 and outer ring 222, described inner ring 221 is connected with described outer ring 222, the inboard of described inner ring 221 has screw thread, described inner ring 221 screw-casings are located on the described screw rod 210, described grab collude 230 be placed in described screw rod 210 the other ends and can be around 210 rotations of described screw rod, the two ends of described screw rod 210 all are fixed with nut 240; The diameter of described retainer plate 220 adapts with the diameter of putamina on the described reverse osmosis membrane group, makes described retainer plate 220 can be placed in the outer surface of described putamina.Described screw rod 210, retainer plate 220 and grab and collude 230 and all can adopt steel matter to make.Described grab to collude have at least two and collude and grab.

Extracting tool of the present utility model in use fixed trap in the putamina of the reverse osmosis membrane group outside, the screw rod of rotation extracting tool, can make screw rod with respect to retainer plate to moving near the direction of membrane component, make grabbing of extracting tool collude gradually and finally catch on film end cap on the membrane component near the membrane component in the putamina; Owing to be fixed in the retainer plate in the putamina outside extracting tool is played the fixed support effect, therefore by rotating the screw rod of extracting tool again, screw rod is moved to the direction away from membrane component with respect to retainer plate, make that grabbing the film end cap that colludes on the pulling membrane component pulls to membrane component outside the putamina.
