Description
Technical field
A kind of new solid-liquid separation filtering device is the utility model is related to, suitable for the material containing sticky solid composition
The separation of solid and liquid of liquid.
Background technology
Filtering is a kind of routine operation in many fields such as medicine, chemical industry, food.Realize the filter method of separation of solid and liquid
Two kinds can be divided into：Full dose filtering is also known as dead-end filtration and cross-flow filtration.Centrifuge, flame filter press, squeezer, press filtration cylinder etc.
Belong to dead-end filtration, be the upstream that material liquid is placed in filtering interface, under the promotion of pressure differential, clear liquid and solid small particles
Through filtering interface, bulky grain is then trapped.Membrane filtration belongs to cross-flow filtration, and material liquid produces two separation in filtering interface
Power, a normal force for being perpendicular to filtering interface, clear liquid is set to pass through filtering interface, another is parallel to filtering interface
Tangential force, the trapped substance of filtering interface is washed away.
In actual production, the application of dead-end filtration is more extensive, and its advantage is device and simple to operate, and its drawback is filtering
During can gradually form filter cake on filtering interface, hinder filtering, reduce the rate of filtration.And formed the solid of filter cake into
Point granularity is smaller, and filtration resistance is bigger, and especially when sticky solid constituent forms filter cake, the rate of filtration can drastically reduce,
It can not even filter.
Membrane filtration is typical cross-flow filtration device, complicated, and cost is high, produces a large amount of waste water during cleaning.Often should
The product high for added value.
Other existing solid-liquid separating filter typically all includes shell and filter element therein, is set on shell
There is lid, after the completion of filtering, solid material is taken out by way of opening cylinder cap.Filtered clearly for large-scale separation of solid and liquid
For device, not only labor intensity is larger, less efficient for the mode of this feeding of uncapping, and easily operating personnel are damaged
And environment is polluted, particularly when liquid phase contains organic solvent.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of simple in construction, feeding not
Open cylinder cap, the solid-liquid separation filtering device suitable for the feed liquid containing sticky solid composition.
To achieve the above object, the utility model provides following technical scheme：A kind of new separation of solid and liquid filtering dress
Put, it includes cylinder cap, cylinder body, filter, cylinder bottom, and wherein filter is arranged on below cylinder body, and filtering cloth jar is divided into cylinder body and cylinder
Bottom two parts, the cylinder body top are provided with charging aperture, and cylinder bottom bottom is provided with filtrate (liquid, it is characterised in that：Cylinder center is also set
There is agitator, cylinder body is also connected with external circulation line.
Wherein external circulation line is sequentially provided with circulation import, circulation inlet valve, membrane pump, loop exit valve and circulation
Outlet, waste liquid outlet is provided between membrane pump and circulation imported valve.The loop exit is opened on side of cylinder block filtering
Above plate, circulation inlet openings are on cylinder cap.
After above structure, solid-liquid separation filtering device of the present utility model has following excellent compared with prior art
Point：
1) stirring and outer circulation are opened in filter process simultaneously so that filter will not be formed in filter process on filter
Cake, ensure that the rate of filtration maintains certain level.
2) when washing, due to stirring the effect with outer circulation, the effect of mashing is played, clean result is better than elution.
3) solid content more and more higher in later stage filtering jar is filtered, stirring and circulation can be closed, will be dense by waste liquid outlet pipeline
Contracting liquid is directly drained, and filter process and reclaiming process need not open cylinder cap.
Preferably, the paddle of the agitator opens turbine type using straight leaf.
Preferably, compressed air inlet is set on cylinder cap.In order to realize cross-flow filtration, material liquid is in filtering interface
Two separating forces are produced, a tangential force for being parallel to filtering interface, are provided by following bad membrane pump outside；Another is vertical
In the normal force of filtering interface, provided when multiple batches of production by the pump for constantly providing material liquid.It can be opened when producing for single batch
Compressed air is opened, to provide vertical normal force.
Brief description of the drawings
Fig. 1 is the structural representation of solid-liquid separating filter of the present utility model.
Wherein, 1, agitator, 2, cylinder cap, 3, cylinder body, 4, filter, 5, cylinder bottom, 6, agitating paddle, 7, charging aperture, 8, filtrate
Outlet, 9, loop exit, 10, waste liquid outlet, 11, membrane pump, 12, circulation import, 13, compressed air inlet, 14, recycle

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in figure 1, the separated part of the present embodiment solid-liquid separator is filter 4, filtering jar is divided into the He of cylinder body 3 by it
The two parts of cylinder bottom 5.Cylinder body 3 is cylinder, and cylinder cap 2 and cylinder bottom 5 are ellipsoidal head.Cylinder cap is provided with agitator 1, compression sky
Gas import 13, circulation import 12, circulation import 12 connect membrane pump 11, are provided with valve 15 between them；Cylinder body upper side
