Abstract
The utility model discloses a novel electrostatic spinning umbrella-shaped spray head, and belongs to the field of electrostatic spinning. The novel electrostatic spinning umbrella-shaped spray head comprises a splitter plate, a hollow cone and fitting screws, and is characterized in that splitter shuttles machined on the splitter plate and evenly distributed taper holes all enable a polymer solution or melt to carry out streamline flow conveniently and enable macromolecular chains to orient in the flow direction. The slant angles of the umbrella-shaped surface of the hollow cone enable the polymer solution or melt to evenly cover the umbrella-shaped surface. When a high voltage is charged, multiple jet flows are formed on the edge of the bottom end of the umbrella-shaped surface, spinning efficiency is improved, and the splitter plate and the hollow cone are connected through the fitting screws. The novel electrostatic spinning umbrella-shaped spray head is easy to machine and convenient to assemble and disassemble, reduces spinning difficulty, and improves the spinning efficiency.
Description
Technical field
The utility model relates to a kind of electrostatic spinning nozzle, belongs to the electrostatic spinning field.
Background technology
Along with the develop rapidly of nanosecond science and technology, electrostatic spinning has caused researcher's extensive concern as a kind of simple method that efficiently prepares continuous nano-fibre.The basic principle of electrostatic spinning is to utilize electrostatic force to prepare superfine fibre as tractive force, and existing multiple polymers makes superfine fibre by method of electrostatic spinning at present.
The rheological equationm of state of the process conditions of electrostatic spinning and polymer self has determined the success or not of spinning.Process conditions mainly refer to spinning voltage and spinning temperature, and the two all must reach certain critical value: spinning voltage is too high can be punctured; The too high meeting of spinning temperature causes depolymerization.The rheological equationm of state of polymer self mainly refers to viscosity, too high its poor fluidity of polymer viscosity, and can stop up shower nozzle, and cause difficulty in spinning, can reduce viscosity although improve temperature, High Temperature High Pressure causes device complicated, difficult design.
Summary of the invention
A kind of novel electrostatic spinning umbrella shape shower nozzle that the utility model proposes, two problems have mainly been solved, one, bellmouth of the even processing that distributes and umbrella shape face all help flowing of polymer solution and melt on it, improved to a certain extent the flowability of polymer solution or melt, two, the shunting of bellmouth and umbrella shape face impels the umbrella shape bottom surface to form multiple jets, improves spinning efficiency.
A kind of novel electrostatic spinning umbrella shape shower nozzle that the utility model proposes, comprise flow distribution plate, hollow cone body and attachment screw, the spreader of processing on the flow distribution plate and equally distributed bellmouth all are conducive to the streamline flow of polymer solution or melt, help macromolecular chain streamwise orientation; The umbrella shape face tilt angle of hollow cone body covers on the umbrella shape face polymer solution or melt uniformly, when adding high voltage, forms multiple jets in umbrella shape face bottom edge, improves spinning efficiency.
A kind of novel electrostatic spinning umbrella shape shower nozzle that the utility model proposes is comprised of flow distribution plate and hollow cone body, the two separate machined, and difficulty of processing is little, and the two connects easily assembling by attachment screw.Compare with traditional capillary, avoided the difficulty of capillary processing, and polymer solution or melt be to be flowed out by equally distributed taper hole, can uniform fold to the umbrella shape face, be conducive to spinning.
Description of drawings
Fig. 1 is a kind of novel electrostatic spinning umbrella shape shower nozzle assembly drawing of the utility model.
Fig. 2 is the utility model flow distribution plate top view.
Among the figure: the 1-flow distribution plate; 2-hollow cone body; The 3-attachment screw; 4-umbrella shape face; The 5-spreader; The 6-bellmouth.
The specific embodiment
A kind of novel electrostatic spinning umbrella shape shower nozzle of the utility model, its implementation process is as follows: flow distribution plate (1) couples together by attachment screw (3) and hollow cone body (2), as shown in Figure 1.When polymer solution or melt arrival flow distribution plate (1), as shown in Figure 2, arrive the upper surface of flow distribution plate (1) by the spreader (5) on the flow distribution plate (1), six bellmouths (6) of evenly offering by the upper surface center of flow distribution plate (1) evenly are divided on the umbrella shape face (4) of 6 strands of liquid arrival hollow cone bodies (2), guiding by umbrella shape face (4) angle of inclination, on the umbrella shape face that covers (4) of uniform liquid, add high voltage this moment, can form uniform a plurality of taylor cone in umbrella shape face (4) lower edge, when voltage reaches certain value, form multiply spinning jet.
Claims (2)
1. novel electrostatic spinning umbrella shape shower nozzle, comprise flow distribution plate, hollow cone body and attachment screw, it is characterized in that spreader and the equally distributed bellmouth processed on the flow distribution plate can make the mobile of polymer solution or melt be streamlined, the umbrella shape face tilt angle of hollow cone body covers on the umbrella shape face polymer solution or melt uniformly, when adding high voltage, form multiple jets in umbrella shape face bottom edge, improve spinning efficiency.
2. a kind of novel electrostatic spinning umbrella shape shower nozzle according to claim 1 is characterized in that flow distribution plate is connected by attachment screw with the hollow cone body.
