TECHNICAL FIELD
[0001] The utility model relates to electrospinning technical field, especially in kind electrospinning constant humidity environment system. BACKGROUND
[0002] Electrospinning is a process of forming fiber filaments in an electric field, wherein the air humidity of the working environment is an important factor affecting the spinning effect, when the air humidity deviates from the required working humidity to a certain extent, the generated fiber cannot be normally deposited on the receiving electrode, the needle tip of the spinning will appear the problem of hanging and floating silk, which affects normal spinning and causes quality problems such as poor spinning uniformity.
[0003] In the prior art, the constant temperature device 01 is usually used to inhale air, and the air treated by constant humidity is supplied into the electrospinning device 02, referring to Figure 1 , to maintain the humidity of the air in the environment of the electrospinning device. However, the constant humidity effect of the constant temperature device is not stable enough, especially when the humidity of the external air is abnormal, the processing capacity and efficiency of the constant temperature device are not enough, resulting in that the humidity of the air supplied into the electrospinning device is not stable enough, and the problem of hanging and floating silk is prone to occur. CONTENT OF THE UTILITY MODEL
[0004] The main purpose of the utility model is to provide an electrospinning constant humidity environment system, which aims to solve the technical problem that the air treated by the constant humidity device in the prior art is directly supplied into the electrospinning device, the humidity of the air is not stable enough, and the problem of hanging and floating silk is prone to occur.
[0005] To achieve the above purpose, the utility model provides an electrospinning constant humidity environment system, which comprises:
[0006] A working room main body is provided with a working space and an air buffer space in the working room main body, the working space is communicated with the air buffer space, the working room main body is provided with an exhaust port, the exhaust port is arranged on one side of the working space, and the working room main body is also provided with a constant humidity air inlet, and the constant humidity air inlet is arranged on one side of the air buffer space;
[0007] An electrospinning device is arranged in the working space;
[0008] A constant humidity device is provided with an air outlet, the air outlet is connected with the constant humidity air inlet, the constant humidity device can supply the air treated by constant humidity into the air buffer space through the constant humidity air inlet, and the exhaust port can suck the air in the air buffer space to the working space and discharge the air in the working space.
[0009] The air outlet of the humidity control equipment is connected to the air inlet, meaning that the humidified air is supplied into the air buffer space. This maintains the humidity within the buffer space within the operating range. Because the buffer space contains a large amount of air, when the humidity of the humidified air deviates from the required operating humidity, the air in the buffer space acts as a buffer and neutralizer, preventing significant fluctuations in humidity even if the humidity of the humidified air is unstable. The exhaust port generates negative pressure, drawing air from the buffer space into the working space and the electrospinning equipment. It also removes any corrosive gases that may be generated during operation from the working space and the electrospinning equipment. This stabilizes the humidity within the electrospinning equipment, reducing the problem of spun yarn snagging and scattering. Furthermore, it removes corrosive gases from the electrospinning equipment and the main working chamber, preventing their spread and potential corrosion of the equipment and harm to operators.
[0010] Preferably, the main body of the workroom is also provided with a constant humidity air return port, which is located on one side of the air buffer space. The constant humidity device is also provided with an air extraction port, which is connected to the constant humidity air return port. The constant humidity device can extract the air in the air buffer space through the constant humidity air return port, perform constant humidity treatment, and then send the air back to the air buffer space through the constant humidity air inlet.
[0011] The constant humidity equipment draws air out of the air buffer space, processes it under constant humidity, and then supplies it back into the air buffer space. This cycle makes the air humidity in the air buffer space more stable and reduces the processing capacity and energy consumption of the constant humidity equipment.
[0012] Preferably, the constant humidity air return port is closer to the working space than the constant humidity air inlet. The constant humidity air inlet is positioned further away from the electrospinning equipment, increasing the distance the humidified air travels before reaching the electrospinning equipment from the air buffer space, thus improving the buffering effect of the air buffer space.
[0013] Preferably, the exhaust port is located on the side of the electrospinning equipment away from the air buffer space. This allows for more efficient airflow within the main working chamber, improves the stability of air humidity, and ensures more complete removal of corrosive gases.
[0014] Preferably, the main body of the workroom is provided with a first door, which is located on one side of the air buffer space. Operators can enter and exit the main body of the workroom through the first door, and closing the first door can prevent air from flowing out of the air buffer space.
[0015] Preferably, the electrospinning constant humidity environment system further includes an entrance / exit transition chamber, which is located outside the first door. The first door is located between the main body of the work room and the entrance / exit transition chamber, and the entrance / exit transition chamber is provided with a second door that communicates with the outside.
[0016] The transition room provides a buffer for the outside air, preventing the air inside the main body of the workroom from directly communicating with the outside air when the first door is opened, thus improving the stability of the humidity inside the main body of the workroom.
[0017] Preferably, a humidity detection device is provided within the air buffer space. The humidity detection device can conveniently detect and monitor the air humidity within the air buffer space.
[0018] Preferably, the workspace also includes an observation room, with a third door connecting the observation room and the workspace. Operators can enter the observation room to observe the electrospinning equipment in operation or perform other tasks. The observation room provides more comfortable air for the operator.

[0028] like Figure 2 and Figure 3 As shown, an electrospinning constant humidity environment system includes a main working room 1, an electrospinning device 2, and a constant humidity device 3.
[0029] The main body of the workroom 1 contains a workspace 11 and an air buffer space 12, which are connected. The main body of the workroom 1 has an exhaust vent 13 located on one side of the workspace 11. The main body of the workroom 1 also has a constant humidity air inlet 14 located on one side of the air buffer space 12. Operators can move within the air buffer space 12. The exhaust vent 13 and the constant humidity air inlet 14 can be installed on the ceiling or wall of the main body of the workroom 1.
[0030] The electrospinning equipment 2 is located in the working space 11. The electrospinning equipment 2 has a window or an open spinning working area, so that the working area of the electrospinning equipment 2 is connected to the working space 11. Air in the working space 11 can enter the working area of the electrospinning equipment 2, and corrosive gases generated by the electrospinning equipment 2 during operation can also be discharged.
[0031] The constant humidity device 3 is equipped with an air outlet connected to a constant humidity air inlet 14. The constant humidity device 3 can supply humidified air into the air buffer space 12 through the constant humidity air inlet 14, and the exhaust port 13 can draw air from the air buffer space 12 into the working space 11 and discharge air from the working space 11. The constant humidity device 3 can use existing air humidity control equipment. The constant humidity device 3 can perform constant humidity treatment based on the relationship between the humidity of the intake air and the working humidity. When the humidity of the intake air is higher than the working humidity, the constant humidity device 3 dehumidifies the intake air; when the humidity of the intake air is lower than the working humidity, the constant humidity device 3 humidifies the intake air.
[0032] The air outlet of the constant humidity device 3 is connected to the constant humidity air inlet 14, that is, the air that has been treated by constant humidity is supplied into the air buffer space 12 to maintain the humidity of the air in the air buffer space 12 within the working humidity range. Since there is a large amount of air in the air buffer space 12, when the humidity of the air after constant humidity treatment deviates from the required working humidity, the air in the air buffer space 12 will have a buffering and neutralizing effect on the supplied air. Even if the humidity of the air after constant humidity treatment by the constant humidity device 3 is unstable, the humidity of the air in the air buffer space 12 will not fluctuate significantly.
[0033] The exhaust port 13 generates negative pressure, drawing air from the air buffer space 12 into the working space 11 and the electrospinning equipment 2, and expelling the air in the working space 11 and the corrosive gases that may be generated by the electrospinning equipment 2 during operation. On the one hand, this can make the humidity of the air in the electrospinning equipment 2 more stable, thereby reducing the problem of spun yarn hanging and floating. On the other hand, it can expel the corrosive gases generated during operation from the electrospinning equipment 2 and the main body of the work room 1, so as to prevent the corrosive gases from spreading and corroding the electrospinning equipment 2 and harming the health of the operators.
[0034] In some specific embodiments, reference is made to Figure 2 The air extraction port of the constant humidity device 3 is connected to the external environment. The constant humidity device 3 can continuously extract air from the external environment, and after constant humidity treatment, supply it into the air buffer space 12.
[0035] In other specific embodiments, reference is made to... Figure 3 The main body of the work room 1 is also equipped with a constant humidity air return port 15, which is located on one side of the air buffer space 12. The constant humidity equipment 3 is also equipped with an air extraction port, which is connected to the constant humidity air return port 15. The constant humidity equipment 3 can extract the air in the air buffer space 12 through the constant humidity air return port 15, perform constant humidity treatment, and then send the air back to the air buffer space 12 through the constant humidity air inlet 14.
[0036] The constant humidity device 3 draws the air out of the air buffer space 12, processes it with constant humidity, and then supplies it back into the air buffer space 12. This cycle can make the air humidity in the air buffer space 12 more stable, and can reduce the processing capacity of the constant humidity device 3 and reduce the energy consumption of the constant humidity device 3.
[0037] Furthermore, the constant humidity air return port 15 is closer to the working space 11 than the constant humidity air inlet 14. The constant humidity air inlet 14 is located further away from the electrospinning equipment 2, which increases the distance that the air treated by constant humidity enters the air buffer space 12 and reaches the electrospinning equipment 2, thereby improving the buffering effect of the air buffer space 12.
[0038] In some specific embodiments, the exhaust port 13 is located on the side of the electrospinning equipment 2 away from the air buffer space 12. This allows for more efficient airflow within the main body 1 of the work chamber, improves the stability of air humidity, and ensures more complete removal of corrosive gases.
[0039] In some specific embodiments, the main body of the workroom 1 is provided with a first door 16, which is located on one side of the air buffer space 12. Operators can enter and exit the interior of the main body of the workroom 1 through the first door 16, and closing the first door 16 can prevent the air from flowing out of the air buffer space 12.
[0040] Furthermore, the electrospinning constant humidity environment system also includes an entrance / exit transition chamber 4, which is located outside the first door 16. The first door 16 is located between the main body of the work room 1 and the entrance / exit transition chamber 4. The entrance / exit transition chamber 4 is provided with a second door 41 that communicates with the outside.
[0041] The transition room 4 can be entered and exited through the second door 41. The space inside the transition room 4 has a certain transition buffer effect on the outside air, so as to prevent the air inside the main body of the work room 1 from being directly connected with the outside air when the first door 16 is opened, thereby improving the stability of the air humidity inside the main body of the work room 1.
[0042] In some specific embodiments, a humidity detection device is provided within the air buffer space 12. The humidity detection device can conveniently detect and monitor the air humidity within the air buffer space 12. The humidity detection device can be a hygrometer, which can be used by personnel to adjust the humidity reading to control the constant humidity device 3, or the hygrometer can be connected to the constant humidity device 3 via a signal connection, allowing the constant humidity device 3 to automatically adjust its operation based on the air humidity within the air buffer space 12.
[0043] In some specific embodiments, an observation room 5 is also provided within the workspace 11, and a third door 51 is provided between the observation room 5 and the workspace 11. The observation room 5 can be accessed through the third door 51, and operators can enter the observation room 5 to observe and wait for the electrospinning equipment 2 to work or to perform other work. The observation room 5 provides a more comfortable environment for the operator.
[0044] In some specific embodiments, the exhaust port 13 is equipped with an exhaust fan. The rotation of the exhaust fan can generate negative pressure to draw out the air inside the main body 1 of the work chamber. The exhaust port 13 can also be connected to a negative pressure pipe, and the other end of the negative pressure pipe is connected to a negative pressure device to generate negative pressure, which can also generate negative pressure to draw out the air inside the main body 1 of the work chamber.
[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
