Abstract
The utility model discloses a formula of book membrane shell structure, include the barrel, locate the cover on barrel top, and locate the spiral wound module in the barrel, barrel bottom center forms the the annular clamped wall, spiral wound module includes the center tube and convolutes reverse osmosis membrane outside the center tube reverse osmosis membrane lies in the top cover outward and is equipped with a sealed rubber ring center tube bottom cover is equipped with the 2nd sealed rubber ring, barrel inside of the top of wall radially outwards forms one section inclined plane, works as when spiral wound module installs in the barrel, a sealed rubber ring replaces on the barrel inside wall and a sealed rubber ring's the height that highly is less than inclined plane on the barrel inside wall, the 2nd sealed rubber ring replaces on the annular clamped wall inside wall, through set up one section inclined plane on barrel inside of the top of wall, when spiral wound module is taken out in the needs dismantlement, only needs take out one section back with spiral wound module hard, and during sealed rubber ring process inclined plane, the frictional force between a sealed rubber ring and the barrel inner wall diminishes, at this moment, only needs less power can directly take out spiral wound module simple operation, labour saving and time saving.
Description
Technical field
This utility model relates to reverse osmosis membrane filter element technical field of structures, particularly to a kind of rolled film membrane shell structure.
Background technology
nullUtilizing reverse osmosis membrane purification water is the most conventional purifying water process technological means，Its principle be impure water under a certain pressure，It is passed to reverse osmosis membrane，Impure water obtains pure water by reverse osmosis membrane after-purification，Impure dense water is then intercepted additionally discharges，Existing reverse osmosis membrane filter element includes putamina and the rolled membrane module being sealingly disposed in putamina，When rolled membrane module is taken out replacing or maintenance in putamina by needs，Need to exert a force from rolled membrane module one end，Owing to being to be tightly connected by sealing ring between rolled membrane module and putamina，The frictional force overcome between sealing ring and putamina is needed during taking-up，This is accomplished by applying bigger power，Owing to the structure of rolled membrane module itself limits，Make to find again the suitable point of application during force，Even if using tool operation to get up the most very inconvenient，Even cause damage，Cause a lot of inconvenience to replacing and maintenance.
Utility model content
Technical problem to be solved in the utility model is to provide the rolled film membrane shell structure of a kind of simple in construction, easy accessibility.
By solving the technical scheme that above-mentioned technical problem is used: a kind of rolled film membrane shell structure, including cylinder, it is located at the cover of cylinder top, and the rolled membrane module being located in cylinder, described cylinder bottom center forms annular securing wall, described rolled membrane module includes central canal and the reverse osmosis membrane being wound on outside central canal, outside described reverse osmosis membrane, it is positioned at top is set with the first O-ring seal, it is set with the second O-ring seal in described central canal bottom, described cylinder inside top wall radially outward forms one section of inclined-plane, when described rolled membrane module is arranged in cylinder, described first O-ring seal is supported on cylinder medial wall and the height of the first O-ring seal is less than the height of cylinder medial wall ramp, described second O-ring seal is supported on annular securing wall medial wall.
Further, described first O-ring seal is y-type seal ring.
Further, described second O-ring seal is O RunddichtringO.
Beneficial effect: in this rolled film membrane shell structure, by arranging one section of inclined-plane on cylinder inside top wall, when rolled membrane module is taken out in needs dismounting, after only need to exerting oneself rolled membrane module is taken out one section, the first O-ring seal is through inclined-plane, and the frictional force between the first O-ring seal and cylinder inboard wall diminishes, now, have only to less power can be directly taken out by rolled membrane module, simple operation, time saving and energy saving.
Accompanying drawing explanation
With embodiment, this utility model is described further below in conjunction with the accompanying drawings；
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the partial enlargement structural representation of this utility model embodiment.
Detailed description of the invention
nullSee figures.1.and.2，This utility model one rolled film membrane shell structure，Including cylinder 10、It is located at the cover 20 on cylinder 10 top，And the rolled membrane module 30 being located in cylinder 10，Cylinder 10 bottom center forms annular securing wall 11，Rolled membrane module 30 includes central canal 31 and the reverse osmosis membrane 32 being wound on outside central canal 31，Outside reverse osmosis membrane 32, it is positioned at top is set with the first O-ring seal 33，It is set with the second O-ring seal 34 in central canal 31 bottom，Cylinder 10 inside top wall radially outward forms one section of inclined-plane 12，When rolled membrane module 30 is arranged in cylinder 10，First O-ring seal 33 is supported on cylinder 10 medial wall and the height of the first O-ring seal 33 is less than the height of cylinder 10 medial wall ramp 12，Second O-ring seal 34 is supported on annular securing wall 11 medial wall.
Wherein, first O-ring seal 33 is preferably y-type seal ring, second O-ring seal 34 is preferably O RunddichtringO, when rolled membrane module 30 is fixed in cylinder 10, owing to the first O-ring seal 33 is big with the contact area of cylinder 10 inwall so that the frictional force between the first O-ring seal 33 and cylinder 10 is bigger.This utility model is by arranging one section of inclined-plane 12 on cylinder 10 inside top wall, when rolled membrane module 30 is taken out in needs dismounting, after only need to exerting oneself rolled membrane module 30 is taken out one section, owing to the effect on inclined-plane 12 makes cylinder 10 inner diameter become big, and then the frictional force between the first O-ring seal 33 and cylinder 10 inwall is diminished, now, it is only necessary to rolled membrane module 30 can be directly taken out by less power, simple operation, time saving and energy saving.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill is possessed, it is also possible on the premise of without departing from this utility model objective, various changes can be made.
