Description
Technical field
The present invention relates to separation technical field of membrane, more particularly to a kind of static casting device and its application method.
Background technology
Membrane technology is separated due to having separation, concentration, purifying and refined function concurrently, there is efficient, energy-saving and environmental protection, molecule again
Level filtering and filter process is simple, the feature such as easily controllable, therefore, be widely used at present food, medicine, biology, environmental protection,
The field such as chemical industry, metallurgy, the energy, oil, water process, electronics, bionical, huge economic benefit and social benefit are generated,
As one of most important means in current separation science.As a kind of assembling form of seperation film, hollow fiber column type film group
Part can maximize seperation film usable floor area, and can be backwashed, cross-flow filtration mode is obtained the benefit of maximum,
Most widely applied.On the make during hollow fiber column-type film components, how will separate membrane fiber and pass through resin with putamina
It is to determine the key of membrane module service life that bonding, which turns into an entirety,.Because gap is smaller between fiber, during casting resin very
Easily there is the space that cast is uneven, bubble is even larger, the appearance of these problems causes occur stress concentration inside resin
Point, or even phenomena such as generation cracking, running, have a strong impact on the separating property and service life of component.
At present, casting resin typically uses horizontal packaging technology, and its step is first horizontal putamina, and membrane fiber is loaded into putamina
It is interior, then be integrally attached to uprightly pour into a mould and poured into a mould on frame.Preparing hollow fiber column type membrane module using the technique has two disadvantages
End, on the one hand, laterally assembling can make that membrane fiber is at random, overlapping intersection, be unfavorable for that its is straight dispersed, and upright caudacoria filament is easy
Knot, make film is damaged to lose separating property, on the other hand, during cast resin is extremely difficult penetrates between the membrane fiber for intersecting and knotting, and leads
Cause cast uneven, reduce the intensity of resin, greatly reduce the service life of membrane module, and resin cracks or silk living be present
Risk so that membrane module is directly scrapped.In addition, the pouring technology needs a large amount of manual operations, waste time and energy and efficiency is low.
The content of the invention
The present invention is directed to the problem of existing resin-cast when preparing hollow fiber column type membrane module is uneven, there is provided Yi Zhongjing
State apparatus for pouring and its application method.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of static casting device, including base and fixed mount, it is characterised in that base bottom is metallic plate, metallic plate
It is provided with hollow metal cuboid, is provided with transmission device inside metal cuboid, actuator beairng is from metal cuboid one
Side is stretched out to form connection rotating shaft, and transmission device is connected with handwheel in adjacent side, and connection rotating shaft end is connected with fixed mount, Gu
It is metal framework to determine frame, and its one end is provided with vertical crossbeam, and crossbeam is provided with hoisting structure, and fixed mount is provided with two clips,
Clip is located at the underface of hoisting structure, the fixed putamina of clip.
Further, hoisting structure is provided with 1-8 liftable hang spring rope.
The application method of static casting device of the present invention, comprises the following steps：
1) chopping and end-blocking：Rotating handwheel makes fixed mount be in plumbness, putamina is fixed on clip, in putamina
Film wire protection sleeve is placed, puts down the hang spring rope on hoisting structure, putamina bottom is reached after passing through film wire protection sleeve, will
Film wire is fixed on hang spring rope, and after lifting hang spring rope makes film wire protect sleeve through film wire, adjustment membrane fiber length passes through film
Shell both ends, the film wire of putamina lower end is fixed with film wire clips, rotating handwheel makes fixed mount carry out chopping after being in horizontality
Operated with end-blocking；
2) pour into a mould：After end-blocking, rotating handwheel makes fixed mount be in plumbness, and removing film wire clips makes film wire divide naturally
Scattered, from putamina lower end, connection casting equipment is poured into a mould, and after completing lower end cast, rotating handwheel makes 180 ° of fixed mount rotation, then
Chopping, end-blocking and pouring operation are carried out from the putamina other end, after completion is integrated poured, rotation clip removes putamina.
The beneficial effects of the invention are as follows：The present invention can realize vertical dress silk, and film wire can be certainly under the Gravitative Loads of radial direction
It is so straight not intersect, reach homogeneously dispersed state, passage is provided for follow-up casting resin, it is dispersed to be advantageous to resin, use
From the pouring type casting resin of putamina lower end vertically upward, the resin of cast can be made more closely knit, be not in bubble or
Tomography, ensure the stability of cast.The present invention is highly moderate, can one man operation, be greatly reduced labor intensity, improve production effect
Rate.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention, and each several part is respectively：
1st, base, 2, connection rotating shaft, 3, hoisting structure, 4, fixed mount, 5, putamina.
