Description
Technical field
The utility model relates to the unlatching of the putamina end cap of membrane module in the membrane separation technique, refers to a kind of putamina end cap opening device especially.
Background technology
Membrane module is a kind of film separating component commonly used in the membrane separation technique, for rolled membrane module, it generally includes putamina 11(as shown in Figure 1, 2), be used for holding separatory film (not shown) in the putamina 11, the sealing installation is provided with end cap 12 in the end of putamina 11, and end cap 12 central authorities are connected with dislysate connector 13.Because film is using a period of time to change, and therefore need open end cap 12 in order to film is taken out.Therefore end cap 12 normally sealing-plug need could take out end cap 12 by special instrument within putamina 11 in putamina 11.
The opener of existing putamina end cap generally has two kinds, as shown in Figure 3 a kind of, this instrument comprises supporting frame 21, fixedly there is back-up block 22 both sides at supporting frame 21, the central authorities of supporting frame 21 are installed with a screw rod 23, this screw rod 23 is fixing by a nut 24, and the below of screw rod 23 is connected with a dislysate tube connector bayonet socket 25 and a clip 26.During use described dislysate tube connector bayonet socket 25 is docked with dislysate connector 13 on the end cap 12, with clip 26 both are linked together afterwards, again two back-up blocks 22 are against the end of putamina 11, rotate nut 24 afterwards, end cap 12 can be taken out in putamina 11.Yet, because dislysate connector 13 is to be threaded with end cap 12, and connector 13 to be metals make, end cap 12 is again that plastics are made, end cap 12 is easy to damage in opening process at its screw thread place like this, causes whole end cap damage to be scrapped.
Another kind of existing putamina end cap opener as shown in Figure 4, this instrument comprises supporting frame 31, the two ends of this supporting frame 31 fixedly have one respectively by the bolt 33 of nut 32 connections.During use, this supporting frame 31 is against the end of putamina 11, again two bolts 33 is spun on respectively on two screws 14 on end cap 12 upper surfaces (as Fig. 2), rotate two nuts 32 afterwards respectively successively, can gradually end cap 12 be taken out in putamina 11.Yet also there is following weak point in use in this instrument: need consume than great strength when the first, using; Need screw two bolts 33 in turn when the second, opening the putamina end cap, program is comparatively loaded down with trivial details; Three, owing to the rotation in turn of both sides bolt, so the application of force is inhomogeneous, and bolt is stuck easily, and the screw thread of bolt weares and teares easily, and service life is short; When four, opening the putamina end cap, owing to do not exert oneself simultaneously in both sides, cause the putamina distortion easily, influence the service life of putamina.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of opening program simple, laborsaving, and the putamina end cap opening device of not fragile end cap and putamina.
For solving the problems of the technologies described above, technical solution of the present utility model is:
A kind of putamina end cap opening device, comprise upper backup pad, lower supporting plate, jack structure and two bolts, this jack structure is installed between the upper and lower gripper shoe, and two are bolted to the both sides of this upper backup pad, and this two bolt is in use in the screw of spiral on the putamina end cap.
Described jack structure is the scissors jack structure, it comprise the saddle that is fixed on the described upper backup pad, be fixed on the base on the described lower supporting plate and be articulated in saddle and base between four connecting rods assuming diamond in shape and arrange, middle drive-connecting shaft place at these rhombus four connecting rods is provided with a transmission screw, and being penetrated with a screw rod, this screw rod one end is provided with a rocking bar.
Described upper backup pad and described lower supporting plate are 90 degree and arrange.
Described saddle and described upper backup pad, perhaps described base and described lower supporting plate are movably connected by bolt.
Described two bolt activities intert in the through hole on described upper backup pad.
After adopting such scheme, the utility model utilizes the principle of jack to reach the labour-saving purpose, utilizes jack can drive the bolt of both sides simultaneously simultaneously, steadily spurs the film end cap, the operation sequence of Jian Huaing not only also can prevent discontinuity and the end cap that causes damages or the putamina distortion.In a word, the utlity model has following advantage: the first, simplified the program of opening the putamina end cap, improved the speed of opening the putamina end cap; The second, reduced labour intensity; Three, minimizing is to the damage of end cap and putamina.

The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is a kind of putamina end cap opening device, as shown in Figure 5, is preferred embodiment of the present utility model.Described device comprises upper backup pad 91, lower supporting plate 92, jack structure 93 and two bolts 94.Wherein:
Described jack structure 93 is installed between the upper and lower gripper shoe 91,92, is used for upper backup pad 91 jack-up.This jack structure can be the scissors jack structure, it comprise the saddle 931 that is fixed on the upper backup pad 91, be fixed on the base 932 on the lower supporting plate 92 and be articulated in saddle 931 and base 932 between four connecting rods 933 assuming diamond in shape and arrange, middle drive-connecting shaft place at these rhombus four connecting rods 933 is provided with a transmission screw 934, and being penetrated with a screw rod 935, these screw rod 935 1 ends are provided with a rocking bar 936.
