Description
Technical field
The utility model relates to a kind of sedimeter; Or rather; Relate to a kind of like this device, this device comprises that filter and filter are prone to change fast and the fluid separation applications assembly of installing, this assembly can be coupled with its jockey that matches and form fluid-tight relationship.
Various liquid is arranged, and the photoresist that for example in microelectronics industry, uses is very expensive.Because related scope must be sub-micrometer range and littler characteristic size, the impurity of controlling this class I liquid I is very necessary.This class I liquid I must carry out filtration treatment before use, otherwise the impurity in the liquid can cause damage to electronic component in microelectronic device production.
Background technology
Two kinds of sedimeters are arranged usually.First kind is to use traditional filter, comprises reusable high pressure resistant shell and removable filter core.Have the joint that links to each other with other part of sedimeter on the shell.More during renew cartridge, need open shell earlier, taking-up needs the filter core changed, with the new filter core shell of packing into, seals shell then.There are a lot of shortcomings in the sedimeter of this use conventional filter.At first, change action need for a long time, waste time and energy, particularly part is through the shell of design demand in the particular surroundings use, and it is very narrow to enter the mouth, especially inconvenience.Secondly,, also comprised certain amount of fluid in the shell, the phenomenon of leak of liquid usually can take place owing to be full of liquid usually in the filter core.At institute's leakage liquid is that leakage liquid will jeopardize the personnel of operate as normal in the zone under dangerous harmful situation, and near equipment is caused potential destroying infection.
Second type be with the permanent welding of filter core on shell, through separator filter core and shell are changed simultaneously.The replacing process comprises to be pulled down whole filter and a new filter is reinstalled in the system of being connected to from sedimeter.In this way, can accomplish at an easy rate and change operation, raise the efficiency, and farthest reduce the operative employee and be exposed to the chance in face of the hazardous chemical, reduce the influence of the potential destruction of equipment, improve the reliability that filtration system connects.
Different types of second class I liquid I filter is arranged in commercial Application.Comprise in wherein a kind of filter that the input and output joint is separately positioned on the filter at the two ends of shell, is called " in-line arrangement " filter.Though this structure has the advantage of self, and commonplace, also there are many shortcomings.At first, when filter when sedimeter is pulled down, the liquid end under be tilted to easily flows out, and leak of liquid occurs, therefore need take special measure to reduce liquid and from device, expose, and avoids dangerous generation.Secondly, sedimeter need be provided with two groups of liquid joints, wherein one group of arrival end in system; And another group is at the port of export of system; The structure more complicated, designing and producing all has great inconvenience, can not satisfy on the market demand to the various liquid filter.
The input and output joint that another kind of sedimeter comprises filter against each other, a end at shell, another forms " T " shape in the side of shell.This device is called as " T shape " filter." T shape " filter has solved much and the relevant problem of " in-line arrangement " filter.And owing to all liquid joints all accumulate on the position, so simplified sedimeter.Yet also there are many shortcomings in " T shape " filter, and wherein important disadvantages is between the bottom of filter core and shell, to produce the space that can not flow, perhaps forms immobilising liquid.At filter liquide is under the situation of very costliness, changes filter at every turn, all can produce a part of dead space, with forming very big waste.
Several kinds of above-mentioned sedimeters all need be made each joint that links to each other with filter respectively.Generally speaking, be through filter and sedimeter are positioned mutually, and be connected mutually with coupling, thereby keep the liquid tight with nipple.Generally, a sedimeter is two joints at least, and majority is three or four joints.And nipple is fastening very inconvenient and sometimes can produce the situation that stripped thread etc. is difficult to seal, and therefore seem wastes time and energy very much.When adopting flexible duct, if having to be coupled when connecting the phenomenon of leak of liquid will not appear once more.All these problems can increase filter when changing the required time.In addition, operating personnel's safety condition does not still obtain enough guarantees, and possibly cause the pollution of production environment.
Therefore, some sedimeters that have quick connection and change and be connected to easily the first-class characteristic of sedimeter have been designed.This type quick connection assembly comprises one group of jointing; These jointings are through unique just being coupled on the one group of jointing that matches with it with simple one-time action or operation hermetically, and this group jointing is fixed on the reusable pedestal.Designed dissimilar mechanisms for accomplishing quick connection location, up to now, all these mechanisms all need form some relative motions between the jointing group, and the most frequently used is turning effort.
People such as Thomsen are at United States Patent (USP) 4; Described a kind of filtration system that is used for water treatment in 654,142, it has disclosed the instance that utilizes separator and reusable termination; Have jointing on the said termination, this jointing cooperates with jointing on the filtered water clean cartridge hermetically.For the ease of the replacing filter assemblies, and two jointings are arranged on the same end of filter, and make it to form the co-axial seal setting.Hold it on one side on the reusable termination at bayonet type locking device of installation on the assembly.During use, but two openings and locking device are connected on the termination that matches with it just fixation kit with the form of liquid sealing.
In another example, people such as Groezinger are at United States Patent (USP) 4,719, disclose a kind of similar assembly and erecting device in 023, and it is the assembly on " rotating replaceable filter " with component description.According to this open text; The connected mode of assembly and erecting device is; At first the bayonet ridge on the handle component is aimed at corresponding latch notch groove in the erecting device; The assembly connector is inserted coaxially in the hole of erecting device, the longitudinal axis runner assembly of winding spare makes the bayonet ridge coupling then, and keeps replaceable filter thus.
More convenient when although quick connection assembly uses, also there are some defectives concerning sedimeter.At first; Connector forms common encapsulant between liquid inlet and outlet; This is unfavorable, because the output stream that the leakage of used seal can cause having purified on the input port is received the not osmosis pollution of the inlet flow of purification, and this pollution possibly not discovered; In addition, quick connection assembly is installed is aimed at input port and the delivery outlet of also carrying filter, also bring and permitted a little inconveniences to installation.
