Abstract
The invention relates to a bidirectional forming device of a hollow fiber blood filtering membrane. The bidirectional forming device comprises a sealed container, a liquid inlet pipe, a filling pipe and concentric dual-pore spinnerets, wherein the filling pipe is communicated with the inner pore of the dual-pore spinneret; the sealed container is externally provided with a distribution pipe communicated with the bottom of the sealed container; the two sides of the distribution pipe are provided with more than six dual-pore spinnerets respectively; and the spinnerets can spin toward the two sides at the same time, thereby greatly improving the production efficiency and reducing the production cost.
Description
Technical field
The present invention relates to a kind of two-way shaped device of doughnut blood filtering membrane.
Background technology
All be the flow of controlling spinning solution by measuring pump during the hollow fiber film on the make at present both at home and abroad, the product of making by this method exists a lot of defectives: the hollow-fibre membrane wall unevenness is even, clearance rate is low, be difficult for realizing industrialization production etc.And some is directly controlled spinning solution with the steady pressure in the container and has remedied above-mentioned defective to a certain extent from the equipment of diplopore spinning head moulding now, still still has improved place.
Summary of the invention
The technical problem to be solved in the present invention is: for the problem that the shaped device that solves existing doughnut filter membrane in the above-mentioned background technology exists, provide a kind of two-way shaped device of improved doughnut filter membrane.
The technical solution adopted for the present invention to solve the technical problems is: a kind of two-way shaped device of doughnut blood filtering membrane, comprise closed container, feed tube, fill pipe and concentric diplopore spinning head, filling pipe communicates with the endoporus of diplopore spinning head, described closed container outer setting has air inlet pipe that communicates with the closed container top and the distributing pipe that communicates with the closed container bottom, both sides are equipped with the diplopore spinning head more than six respectively on the distributing pipe, can realize simultaneously to both sides spray silk, finish the workload of common two covering devices with a covering device, greatly reduce cost, improved production efficiency.
Further, on the distributing pipe of the present invention pressure sensor is housed, the control valve of regulator solution surface pressure is housed on the air inlet pipeline, the output of pressure sensor is connected with the input of controller, the output termination control valve of controller, pressure sensor feeds back to controller with the fluid pressure signal at distributing pipe place, and controller sends the admission pressure that output signal control and regulation valve is controlled container after relatively with detected force value and setting value, keep the diplopore spinning head stable go out flow quantity.
The invention has the beneficial effects as follows, again will be directly when controlling the variety of problems that the flow of spinning solution produces by measuring pump when the present invention efficiently solves hollow fiber film on the make controlling spinning solution with the steady pressure in the container improves from this equipment of diplopore spinning head moulding, make production efficiency improve greatly, production cost reduces.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the side view at distributing pipe of the present invention place.
