Description
Technical field
The utility model relates to a kind of filter, and particularly, the utility model relates to a kind of filter cylinder extension type filter, is applied to adopt the filtration system of filter cylinder filter process sewage.
Background technology
Can often produce the sewage that further to handle in a large number in the enterprise production process, especially no longer may untreated sewage directly be discharged as manufacturing enterprises such as iron and steel enterprises.
In the process of handling these sewage; filter is indispensable a kind of device on the conveyance conduit; filter is installed in the entrance point of pressure-reducing valve, relief valve, water level valve or miscellaneous equipment usually, is used for eliminating the impurity in the medium, with the normal use of protection valve and equipment.After entering the filter cylinder that is equipped with the certain specification filter screen when fluid, its impurity is blocked, and the filtrate of cleaning is then discharged by strainer screen.Therefore, Filter cartridge is to need the often parts of cleaning at ordinary times, generally gets final product reloading after the filter cylinder taking-up cleaning treatment.
At present, in the actual production of enterprise, using filter miscellaneous, have big have little, have precision high have precision low, but these filters all have a kind of common characteristic: their filter cylinder all is non-telescoping.There is following defective in the non-telescoping formula filter of this filter cylinder: (1) is to because of being subjected to the filter of device space restriction place, just can't extract filter cylinder out completely, carry out fully effectively cleaning, can only the be passive part of taking out be cleaned according to on-site actual situations, and the part of failing to take out, filter cylinder just can't be cleaned timely and effectively, and the dirt on filter cylinder surface will be tied more and more, finally influences the filter effect of filter.When (2) changing filter cylinder,, must sever the outlet conduit of filter, so not only increase maintainer's working strength, and increased the overhaul of the equipments time owing to filter cylinder can't be extracted out.
Present domestic following several the relevant patents that mainly contain.
Application number/patent No.: 200420093896 patent names: flexible rotation, the filter cylinder telescoping mechanism of holding concurrently of a kind of filter of hydraulic filter.This patent provides a kind of mechanism that directly can be enclosed within the also adjustable filter cylinder elongation that just can extend within the specific limits on the plain filter filter cylinder outward, realizes the elongation of filter cylinder by hydraulic pressure.The characteristics of this patent are that filter cylinder length can often adjust and rotatable, are mainly used in the filtration in the mailbox, and use hydraulic-driven, and patent structure complexity, operation are various, are not suitable for the filtration system of sewage disposal.
Application number/patent No.: 91224107 patent names: the telescopic millipore filter of a kind of vacuum chamber.This patent is a kind of millipore filter, what its vacuum cylindrical shell adopted is the extension type structure, fit constitutes by the upper bush that has loam cake and inside and outside having the lower sleeve of base, upper and lower sleeve can endwisely slip along it mutually, it makes vacuum cylinder can do double-filtration and series connection use by the improvement to the vacuum cylinder body structure.This patent mainly is applicable to the investigation and analysis of water quality such as ocean, rivers, lake, belongs to the film separation field, adopts membrane filtration, as is applied to the effluent treatment and filtering system, will influence filter effect, makes the filtration cost too high.
The utility model content
Can not extract out fully in order to solve in the site examining and repairing operation filter cylinder, it is not thorough to influence Filter cartridge surface dirt removal, cause the problem of filter poor filtration effect, the purpose of this utility model is to provide a kind of filter cylinder extension type filter, make that whole filter cylinder is fully cleaned in maintenance process, guarantee filter effect, reduce maintainer's working strength, shorten the repair time, increase work efficiency and overhaul benefit.
The technical solution of the utility model is, a kind of filter cylinder extension type filter that is used for sewage disposal, comprise inlet channel, interior inlet channel, shell and filter cylinder, supporting back seat is connected with shell is inboard, flanged pipe is connected with the shell outside, it is characterized in that described filter cylinder comprises outer filter cylinder and interior filter cylinder, described outer filter cylinder is connected with interior filter cylinder fit, and interior filter cylinder is along outer filter cylinder axial stretching.
Outer filter cylinder embeds in the annular groove that supports back seat near interior inlet channel one side, support back seat and shell inboard by being welded to connect, the flanged pipe and the shell outside are by being welded to connect, interior filter cylinder is fastening by fastening bolt near outlet conduit one side, the telescopic illiteracy plate that is used to seal inserts flanged pipe, interior filter cylinder is flexible to be positioned by dog screw behind desired location, between outer filter cylinder and the dog screw sealing ring is arranged, back-up ring is used to filter cylinder to provide support, it is fastening that fastening bolt utilizes bolt that filter cylinder is carried out, and telescopic illiteracy plate has two effects, and one provides the power of axially fastening, second effect is the sealing that is used for flanged pipe, prevents that liquid flows out in the filter.
The utility model adopts the extension type filter cylinder to stretch by the mutual of inside and outside filter cylinder, effectively dwindles the filter cylinder effective length, thereby realizes the change of filter cylinder entire length aspect, is applicable to the restricted clearance filter system, belongs to the single-stage filtration system.Realization filter cylinder effective length is dwindled, and is convenient to the purpose of using under the situation of restricted clearance.Guaranteeing under the impregnable prerequisite of filter effect, guarantee to accomplish to reduce of the dependence of the replacing washing and cleaning operation of Filter cartridge in actual use, make that whole filter cylinder is fully cleaned, reduce maintainer's working strength the space, shorten the repair time, increase work efficiency and overhaul benefit.
