Enhanced flash evaporation/electrospinning composite spinning equipment

A flash evaporation/electrospinning composite spinning equipment, comprising

• a flash spinning equipment,
• an electrospinning equipment, and
• a grounded receiving conveyor belt;
• wherein the flash spinning equipment comprises a flash spinning spinneret unit, the flash spinning spinneret unit comprises a first spinneret, and the first spinneret is grounded;
• the electrospinning equipment comprises a high-voltage power supply and an electrospinning spinneret unit, the electrospinning spinneret unit comprises a second spinneret, and the second spinneret is connected to the high-voltage power supply;
• wherein the first spinneret and the second spinneret are both located above the receiving conveyor belt at opposite positions with a distance of D, and a value range of D is 15-40 cm;
• wherein the flash spinning equipment further comprises a first blowing device;
• the electrospinning equipment further comprises a second blowing device;
• wherein the first blowing device or the second blowing device comprises an air supply device, an inner cylinder, an outer cylinder, a first vertical plate, and a second vertical plate;
• wherein the outer cylinder is sleeved on the inner cylinder, the outer cylinder and the inner cylinder are coaxial and flush at both ends, and one end of the outer cylinder and the inner cylinder is sealed by the first vertical plate simultaneously, while the other end of the outer cylinder and the inner cylinder is connected by the second vertical plate;
• the inner cylinder, the outer cylinder, the first vertical plate, and the second vertical plate together form a sealed cavity;
• wherein the outer cylinder is provided with an intake hole, and the intake hole is connected by an intake pipe to the air supply device outside the outer cylinder;
• the inner cylinder randomly distributes a plurality of holes;
• wherein a distance between the second vertical plate of the first blowing device and the second vertical plate of the second blowing device is X, and X is greater than 0;
• and
• wherein the first vertical plate of the first blowing device is sleeved on the first spinneret, so that a jet ejected from the first spinneret enters the inner cylinder of the first blowing device;
• the first vertical plate of the second blowing device is sleeved on the second spinneret, so that a jet ejected from the second spinneret enters the inner cylinder of the second blowing device.
