Description
Technical field
The present invention relates to filtering material technical field, in particular to the manufacture method of sintered porous filtration membrane.
Background technology
In Chinese invention patent CN104874798A, CN104959612A, CN104874801A and CN104959611A
In disclose a kind of manufacture method of sintered porous filtration membrane, the manufacture method includes preparing diaphragm and sintering process, its
In, diaphragm needs continuously to sinter to obtain the structure in uniform aperture and homogeneous in multiple temperature sections, higher so as to obtain
Mechanical strength.Traditional vacuum/the atmosphere sintering of existing chaffy sintering process generally use, after diaphragm shove charge, in sintering furnace
For temperature according to temperature programming and Temperature fall, diaphragm keeps certain in low-temperature zone, middle-temperature section and high temperature section successively in sintering furnace
Time, 150 DEG C or so taking-ups then are naturally cooled to stove, that is, obtain sintered porous filtration membrane.Due to the burner hearth of sintering furnace
For single sintering space, diaphragm further takes out after the completion of it must be sintered if entering burner hearth, and can not be put into during sintering new
Diaphragm, otherwise can cause the quality for admitting air into burner hearth and influenceing sintered porous filtration membrane, therefore can only be in a upper film
Next diaphragm can be just put into by, which being taken out after the completion of piece sintering, is sintered, therefore production capacity is relatively low.Simultaneously as the sintering process cycle
It is long, and the stove stand-by period is stopped, therefore the low subject matter of sintering efficiency also be present in above-mentioned vacuum/atmosphere sintering.
The content of the invention
It is a primary object of the present invention to provide the manufacture method and equipment of sintered porous filtration membrane, to solve existing skill
The problem of production capacity existing for art is low low with sintering efficiency.
To achieve these goals, there is provided a kind of manufacturing equipment of sintered porous filtration membrane.The sintered porous mistake
Filter film is fabricated by diaphragm through the manufacturing equipment, and the manufacturing equipment includes：
In the spray body of membrane surface spraying separation layer, the separation layer is included in relatively described under sintering condition
Diaphragm shows as inert inert substance；
Diaphragm after spraying separation layer is wound into the winding mechanism of the film base of column；
The sintering mechanism for being used to transmit the conveyer belt of the film base including reative cell and through the reative cell, the reaction
Room includes low-temp reaction room, medium temperature reative cell, pyroreaction room and the cooling chamber being sequentially connected；
The protection gas conveying mechanism of input protection gas into the reative cell；
Control the operating of the conveyer belt, sintering mechanism entrance and exit opening and closing and protect the stream of gas
The controlling organization of amount.
Firstly, since contain separation layer, thus diaphragm can wind after be put into reative cell and sinter, without worrying that adhesion shows
As sintering efficiency is obviously improved；Secondly, sintering mechanism has multiple reative cells and conveyer belt, therefore film base can carry out flowing water
The sintering of wire type, saves the heating-up time and cool time, the utilization rate for sintering mechanism are obviously improved.The manufacturing equipment knot of the present invention
Structure is simple, completes to be obviously improved using the production of continuous-flow type, production capacity from the sintering that sprays to of diaphragm；If in order to be readily transported and thing
First by the diaphragm pre-roll, then uncoiling mechanism can be set up before spray body so that the diaphragm in pre- wound membrane base to be deployed.This
Outside, the controlling organization can also control heating rate in each reative cell and the temperature of individual reative cell is monitored.Film base
Successively after low-temp reaction room, medium temperature reative cell, pyroreaction room and cooling chamber, the diaphragm in film base is converted into the sintering
Porous filtering film, and the sintered porous filtration membrane still keeps the shape of film base, and do not deform.
Further, the diaphragm includes supporter and is attached to the coating of supporting body surface, and the coating is by being sprayed on
The slurry drying of the supporting body surface forms, and the slurry includes material powder, bonding agent and dispersant；The sintered porous mistake
