Description

Counter-infiltration system film end cap extracting tool

Technical field

This utility model relates to a kind of end cap extracting tool, particularly to a kind of counter-infiltration system film end cap extracting tool.

Background technology

Along with industrial development and the shortage of water resource, nanofiltration, reverse osmosis technology application more extensive, nanofiltration, anti- One vitals of penetration equipment is exactly putamina, and existing market mainly has rustless steel and the putamina of two kinds of materials of fiberglass, its Middle the latter's reliable in quality, low cost, so applying relatively broad.During pure water preparation and Treated sewage reusing, nanofiltration and reverse osmosis Permeable membrane, along with the passage of the time of operation, will occur dirty stifled, cause the decline of film salt rejection rate and aquifer yield, be therefore accomplished by film Being carried out or change, and membranous system is all operation with pressure, the dismounting of film end cap is exactly an important link.At present, existing The most dangerous property of dismounting certain methods of some glass steel membrane end caps and destructive drawback: one is to push open with system pressure.This The method of kind is to lay down screw and the jump ring of film end cap, then starting device, is pushed open by system pressure.This method is endangered very much Danger, system running pressure is all more than 1 MPa, can be to the security presence hidden danger of operator, it is also possible to can cause film end cap Breaking, operation needs the plural talent to complete；Two is to pull with screw rod.This method is to twist with two relatively long bolts Entering the screw hole of film end cap, then two people pull outward with the instrument of vice one class respectively, and this method is relative to the first side The most comparatively safe, if but firmly inequality or conference of exerting oneself cause the damage of film end cap screw thread, it is also desirable to and at least two people grasps Make, the open a kind of extracting tool of knowing clearly of China Patent Publication No. 201922402U, but this extracting tool structure is complicated, all parts Can not first split assemble again, mobile inconvenience.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned present on the dismounting of counter-infiltration system film end cap in prior art asking Topic, it is provided that a kind of counter-infiltration system film end cap extracting tool.

For realizing the purpose of this utility model, have employed following technical scheme: counter-infiltration system film end cap extracting tool, Including a central shaft, the whole length of central shaft is provided with screw thread, central shaft includes an increased diameter head, increased diameter head On be provided with screw thread, the screw thread in increased diameter head matches with the screw thread in the apopore on putamina end cap, on center shaft It is arranged with stress baffle plate, the central shaft after stress baffle plate is equipped with rotation nut, further, described rotation nut Offer three screws on circumference, three screws are connected with three bolts as the arm of force, further, at described center Axle afterbody offers perforation, can wear handle in perforation.

Positive Advantageous Effects of the present utility model is: this tool construction is simple, it is easy to making, the used time is not removable Each parts preserve respectively, assemble during use, and this device applies safety in the dismounting of counter-infiltration system film end cap high, permissible Easily being disassembled by the putamina end cap on nanofiltration, reverse osmosis equipment, whole operating process had both ensured the people of operator Body safety, and overall structure is simple, easy to operate, it is simple to installation and removal.

Accompanying drawing explanation

Fig. 1 is schematic diagram when this instrument and dismounting end cap.

Fig. 2 is the schematic diagram rotating nut in this instrument.

Detailed description of the invention

In order to explain enforcement of the present utility model more fully, it is provided that embodiment of the present utility model.These implement real Example is only to elaboration of the present utility model, is not intended to scope of the present utility model.

In conjunction with accompanying drawing explanation further details of to this utility model, accompanying drawing is respectively labeled as: 1: perforation；2: central shaft； 3: rotate nut；31: screw；4: screw rod；5: increased diameter head；6: stress baffle plate；7: film end cap；8: putamina；Counter-infiltration system Putamina end cap extracting tool, including a central shaft 2, is provided with screw thread in the whole length of central shaft, central shaft includes one is big Diameter head 5, increased diameter head is provided with screw thread, the screw thread in increased diameter head and the spiral shell in the apopore on putamina end cap Stricture of vagina matches, and is arranged with stress baffle plate 6 on center shaft, and the aperture on stress baffle plate is less than increased diameter head 5, stress baffle plate 5 After central shaft on be equipped with rotation nut 3, rotate on nut circumference and offer three screws, 31 show a spiral shell Hole, is connected with three bolts as the arm of force in three screws, shown in 4 for screw rod, central shaft afterbody offers perforation 1, wears Hole 1 can wear handle, figure is shown without handle.

This instrument is as follows in using method:

(1) fixed screw, the cutting ferrule of film end cap are unloaded, then the plug of film end cap 7 center pure water water outlet oral pore is twisted Get off；

(2) being inserted by handle in central shaft perforation, both hands hold handle two ends, are twisted by the increased diameter head screw thread of central shaft To film end cap central pure water outlet position, tighten, take out handle；

(3) putamina 8 edge it is adjacent to after being worn on central shaft by middle part stress baffle plate；

(4) screw rod rotated on nut is installed, rotation nut is screwed onto on central shaft；

(5) rotate rotation nut to turn clockwise, owing to stress baffle plate withstands in nanofiltration, counter-infiltration system putamina outer end On, central shaft moves forward relative to stress baffle plate, thus promotes end cap to move and progressively make it remove from putamina.

Extracting tool of the present utility model is stainless steel, corrosion-resistant, be difficult to get rusty, it is ensured that screw thread and nut are prolonged resistance to With.After describing embodiment of the present utility model in detail, one of ordinary skilled in the art is clearly understood that, is not taking off Can carry out various change and amendment under above-mentioned claim and spirit, all according to technical spirit of the present utility model to Any simple modification, equivalent variations and the modification that upper embodiment is made, belongs to the scope of technical solutions of the utility model, and this Utility model is also not only restricted to the embodiment of example in description.
