Description

A kind of combined filter

Technical field

Filtering and cleaning technique field is the utility model is related to, more particularly to a kind of combined filter.

Background technology

Filter is indispensable a kind of device on pumped (conveying) medium pipeline, is typically mounted on pressure-reducing valve, relief valve, Ding Shui Position valve, the import end equipment of square work filter miscellaneous equipment.Filter is by cylinder, stainless steel filtering net, blowdown part, transmission device And electric control system composition.After the filter cylinder of strainer screen, its impurity is blocked pending water, when needing to clean When, as long as dismountable filter cylinder is taken out, reloaded after processing, therefore, working service is extremely convenient.Filter except In-line filter, double-drum filter and high pressure filter also have many kinds, for example laminated filter, sand rod filter, carbon filter, plate Frame filter, active carbon filter, diatomaceous earth filter, millipore filter etc., cardinal principle are all the holes using filter medium Footpath retains the material smaller than pore size of media, and the filter medium having certainly also has the special-effects such as absorption.Big multiple filter is anti- Wash also without so bothering, as long as the medium can imported with clear water from one end of filtering water outlet in reverse backwash filter Reach fine backwash effect.In the prior art, the filtering for water quality or fluent material has many filters, but has suitable one Partial filter or filter filtering be not thorough, always has more or less remnants, and some is then the longevity used Life is by impurity or needs filtrate corrosion in itself and reduces a lot, and these are sizable dry for production process Disturb, and most filter, its filter can not be split, once cause many filter parts damages to be equal to entirety Scrap, be a kind of greatly waste.

Utility model content

The technical problems to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of combined filter.

In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：

A kind of combined filter of the utility model, including shell, upper capping and transparency window, the shell side is provided with can Tear formula connecting plate open, the removable connecting plate is connected with three fixed plates, three described fixed plate one end by three sealing rings It is connected to coarse filter, middle filter and fine filtrator, the coarse filter, the middle filter and the fine filtrator The other end is connected to the fixed plate, and the fixed plate passes through sealing ring and the cage connection, the shell both ends The upper capping and lower capping are connected to, and the upper capping is connected with outlet, the lower capping is connected with inlet tube, The outlet and the inlet tube are connected to connector, and the shell one side is provided with the transparency window.

Preferably, the removable connecting plate and the enclosure during cage connection are sealing state, and described Removable connecting plate is made up of PVC material.

Preferably, the shell, the upper capping and the lower capping are made up of stainless steel material.

Preferably, it is seamlessly connected between the transparency window and the shell, and the transparency window is made up of safety glass.

The beneficial effect that the utility model is reached is：The filtering of three different levels is provided with inside the combined filter Device, the situation that can be filtered out impurity step by step and reduce blocking occurs, and the combined filter can be split, and work as filter During using to the life-span upper limit, user can be drawn off replacing new filter, and user can also according to oneself Need the filter inside the combined filter being substituted for the filter of different-effect, in addition, the combined filter The transparency window made of safety glass is additionally provided with, user can clearly be observed that the filtering shape inside the combined filter The working condition of condition and filter.
