Description

Full-automatic pressure filter
Technical field
The present invention relates to a kind of full-automatic pressure filter.
Background technology
Filtering refers to the process of that smoothing out with the fingers fluid purification by special device purifies, and the mode of filtering is very much, the thing system used Very extensively, solid-liquid, solid-gas, bulky grain, little particle are typical.
Filtering is the liquid in motive force or other external force effect low suspension liquid (or the gas that generates heat containing solid particle) (or gas) passes through medium, and solid particle and other materials are retained by filter medium, so that solid and other materials and liquid (or gas) separated operation.
It can be divided into gravity filter, pressing filter and vacuum filter by filtered driving force;By the property of filter medium Granular media filter, filter cloth media filtration machine, porous ceramic medium filter and pellicle media filtration machine etc. can be divided into;Press Operating method can be divided into batch filter and continuous filter etc..
Filter plant is totally divided into two classes of vacuum and pressurization, and vacuum types are common rotating cylinder, disk, horizontal belt etc., adds Pressure class is common press filtration, squeezing, dynamic filtration and rotary-type etc..
Membrane filtration
The filter core made of the multiple materials such as wire, filter cloth, filter paper, yarn, cellular plastic, micropore ceramics, is fixed on On tube sheet, load in pressure-resistant staving, filter area is in 0.2Mpa. filtering accuracies in 3-30m2, operating pressure>The essence of 0.1um Filtering or superfinishing filtering, small lot production are used.
Intermittent pressing filter
Operating pressure:0.3-0.8Mpa, reaches as high as 3.5Mpa, smaller suitable for solid, liquid density contrast and be difficult to what is settled Separation, or solids content is high and requires the liquid clarified, or ask solid-phase recovery high, the low occasion of filter cake water capacity, Filter press moral filtered driving force is big, and filtering rate is high, and unit filter area floor space is small, to the adaptable of material, mistake Filtering surface product range of choice is wide, and application is quite varied.Shortcoming is intermittently operated, low production efficiency, and labor intensity is high.
Drum pressurizing filter
Operation is continuous, and filter cake water capacity is low, and washing effect is good, and wash water consumption is low, and maximum filtering area is 8m2 at present, behaviour Make pressure as 0.3Mpa or so.Shortcoming is complicated, maintenance difficult, suitable for large-scale production.
In conclusion existing pressure filter has the defects of various, no any type pressure filter disclosure satisfy that client Many filtration needs.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of applied widely, good separating effect, simple in structure, easy to operate, peace Complete reliable full-automatic pressure filter.
To achieve the above object of the invention, the full-automatic pressure filter of the present invention, including cylinder body, lid are located at the top on the cylinder body Lid, the cylinder body are equipped with locking flange cylinder, locking flange bearing, locking flange and head cover cylinder, head cover bearing block, institute The power output end for stating head cover cylinder is connected with head cover push rod, shaft is equipped with the head cover push rod, the shaft is arranged on On the head cover bearing block, by the head cover bearing seat supports, the head cover cylinder is equipped with cylinder reset valve, the head cover Bearing block is equipped with head cover valve, locking flange valve, and the locking flange valve is by plastics tracheae and is arranged on the cylinder Hermetic seal valve on body is connected with hermetic seal blow valve;
The cylinder interior is equipped with filter core, and the filter core is superimposed using five layers of stainless steel cloth, what vacuum-sintering formed Sintered meshwork, five layers of net of the filter core are by protective layer, precision controlling layer, dispersion layer and multilayer enhancement layer composition;
The bottom of the cylinder body is connected with discharge nozzle, and the cylinder body is equipped with two connection cylinder interiors and the discharge nozzle Side pipe, the nozzle position of side pipe connection cylinder interior is higher than the filter core, side is respectively equipped with the side pipe Side valve;
The on/off valve that flange valve is source of the gas is locked, locking flange valve is opened, utilizes pushing away for air pressure pusher cylinder Bar, and then locking flange movement is promoted, lock locking flange;Hermetic seal valve is opened, jacks up locking flange and head cover tetrafluoro Seal washer, makes head cover be sealed with cylinder body;
Hermetic seal blow valve is closed in filtering, is opened hermetic seal blow valve, is made the hermetic seal of head cover and cylinder body Open, then open locking flange valve, open locking flange, open head cover;
In pressure filter feed liquid higher than sintering net height when, open side valve, feed liquid by periphery sinter net filtration and Bottom filter screen filtration, when feed liquid is less than sintering net height in pressure filter, closes side valve, feed liquid enters bottom screen mistake Filter.
Further, the lower section of the filter core is equipped with more studs arranged in parallel.
