The technical scheme that the utility model technical solution problem is taked is: a kind of liquid precision filter, comprise housing and the filter that is positioned at housing, described housing is the cylinder that is provided with upper cover and low head, be provided with inlet, liquid outlet and the sewage draining exit that communicates with the housing inner chamber at described low head place, described filter comprises filter plate and pressing plate; It also comprises supporting plate, center hold-down mechanism and some cylindrical hold-down mechanisms; It is an integral body that described filter compresses sealing and fixing by supporting plate, some filter plates and pressing plate respectively through center hold-down mechanism and some cylindrical hold-down mechanisms, and when the center hold-down mechanism discharges, described filter can with the housing overall separation.
As a kind of preferred, described cylindrical hold-down mechanism is formed by being connected in slide bar, wiper block and the clamp nut that supporting plate and top is provided with screw thread.
As a kind of preferred, described center hold-down mechanism is made up of the clamp nut that is fixed in central shaft, trim ring and band handle that low head and top is provided with screw thread.
As a kind of preferred, described filter plate is formed through making up fixedly by two opposing filter discs, filter plate inner ring and filter plate outer ring.
As a kind of preferred, described pressing plate is connected and fixed through rod member by pressing plate inner ring and pressing plate outer ring and forms.
As a kind of preferred, described low head is coniform, and the middle part of described low head is provided with pipe shape brace table, and described filter is carried on the pipe shape brace table.
In the utility model, described pipe shape brace table with the pipe be support and on establish table top so that filter can stably be carried on the pipe shape brace table.At the housing inner chamber, the outside of described filter and described filter plate interlayer space constitute former sap cavity, and the inner space of the middle part of described filter and described filter plate inner space and described pipe shape brace table constitutes clean sap cavity; Described inlet communicates with former sap cavity, and described liquid outlet communicates with clean sap cavity, and described sewage draining exit communicates with former sap cavity.
Critical component of the present utility model is a filter.Filter is carried on the pipe shape brace table, from bottom to top, is supporting plate, pressing plate, filter plate successively, pressing plate and filter plate multilayer are overlapping, are top pressing board then, between pipe shape brace table and supporting plate, and between supporting plate and the pressing plate, be equipped with sealing ring between pressing plate and the filter plate; The lower end of cylindrical hold-down mechanism slide bar is connected in the picking up the ears of periphery of supporting plate, and wiper block places on the pressing plate outer ring of top pressing board, compresses through clamp nut; The bottom at the pipe shape brace table center that is arranged on the low head middle part is fixed in the lower end of center hold-down mechanism central shaft, and trim ring places on the pressing plate inner ring of top pressing board, and sealing ring is set therebetween, and the clamp nut through the band handle compresses then.Owing to adopted cylindrical hold-down mechanism and center hold-down mechanism two covers to compress mechanism, carry out cylindrical and center and compress sealing respectively, make the installation of filter quick more reliable, improved withstand voltage properties.
Being provided with of filter has been divided into two parts with the housing inner chamber, the former sap cavity that first filter filter plate interlayer space outside and that linked up by set through hole on the pressing plate outer ring constitutes, it two is middle parts of filter, promptly filter plate and pressing plate inner ring and the central space that form overlapping through multilayer, by the pressing plate inner ring on the clean sap cavity that constitutes of the inner space of the filter plate inner space linked up of set through hole and pipe shape brace table.
During actual motion, stoste enters former sap cavity through inlet, after filter plate filters, enters clean sap cavity, flows out from liquid outlet then.Behind the operation certain hour, can pass through sewage draining exit, impurity screening is cleared up.Because lower sealing is cone shape, so it is very convenient to remove contamination.In the time of need cleaning as filter plate, can back out the clamp nut of band handle, discharge the center hold-down mechanism, filter integral body from housing is hung out, be easy to clean.
The beneficial effects of the utility model are: realize that unit space inner filtration area is big, speed is fast, flow is big, efficient high in, realize filter quick for installation reliable, clean the purpose convenient, that blowdown is smooth and easy, resistance to pressure is good.
