[0027] Based on the difficulties in sampling and transfer operations in small-scale experiments of Lyocell fiber spinning, the present application provides a heat-insulating transfer device, which can be used to transfer the Lyocell fiber spinning solution and maintain the fluidity of the Lyocell fiber spinning solution.

[0028] Specifically, Figure 1As shown, the heat preservation transfer device may include a heat preservation barrel 10, a barrel cover 20, a liquid collection assembly 30 and a circulating heating device (not shown in the figure), the heat preservation barrel 10 includes an outer barrel body 11 and an inner barrel body 12 arranged in the outer barrel body 11, and a heat preservation cavity 13 is provided between the outer barrel body 11 and the inner barrel body 12, and the outer barrel body 11 is provided with a heat preservation liquid inlet 131 and a heat preservation liquid outlet 132 connected to the heat preservation cavity 13; the inner barrel body 12 has a glue liquid cavity 14 for accommodating glue liquid, and the inner barrel body 12 is provided with a glue liquid inlet 141 and a glue liquid outlet 142 connected to the glue liquid cavity 14. The barrel cover 20 is fixedly connected to the heat preservation barrel 10 to cover the glue liquid inlet 141, and the barrel cover 20 is provided with an air source interface 21 connected to the glue liquid cavity 14 and used to access a compressed air source. The liquid taking assembly 30 includes a liquid taking valve 31 and a liquid taking pipe 32. The liquid taking valve 31 is connected to the glue liquid outlet 142, and the liquid taking pipe 32 is connected to the liquid taking valve 31. The circulation heating device is connected to the insulation liquid inlet 131 and the insulation liquid outlet 132, respectively, for circulating and heating the insulation liquid in the insulation chamber 13.

[0029] It is understandable that when using the heat preservation transfer device to transfer the Lyocell fiber spinning dope, the barrel cover 20 can be opened first, the spinning dope to be transferred can be quickly injected from the dope inlet 141, and then the barrel cover 20 can be closed. After the insulation liquid is heated to about 100°C by the circulation heating device, the heated insulation liquid is injected into the insulation chamber 13 from the insulation liquid inlet 131 by the circulation heating device, and the insulation liquid after heat exchange is discharged from the insulation liquid outlet 132. The circulation of the insulation liquid can heat and insulate the dope chamber 14. When it is necessary to sample or discharge the spinning dope, the compressed air source can be connected through the air source interface 21 on the barrel cover 20, and the liquid extraction valve 31 can be opened at the same time. Under the pressure of the compressed gas, the spinning dope can be quickly discharged from the liquid extraction pipe 32. In this way, the heat preservation transfer device can maintain the Lyocell fiber spinning dope so as to transfer the spinning dope from the manufacturing device to the spinning device.

[0030] Optionally, in some embodiments, the insulation liquid may be pressurized water or oil or other safe liquids that can be used in an environment of less than 150°C.

[0031] The heat preservation transfer device can be used for transferring the Lyocell fiber spinning with the coagulation temperature of the glue solution being less than 100° C. and the kinematic viscosity being less than 20000 Pa·s.

[0032] The heat preservation transfer device can withstand an internal pressure of not less than 1.6 MPa.

[0033] Alternatively, if Figure 1As shown, in one embodiment, the inner barrel body 12 includes an annular barrel wall 121 connected to the upper side of the outer barrel body 11 and a conical barrel wall 122 connected to the annular barrel wall 121, the upper end opening of the annular barrel wall 121 is the glue inlet 141, and the lower end opening of the conical barrel wall 122 is the glue outlet 142. The conical barrel wall 122 can guide the glue to the glue outlet 142 to prevent the glue from remaining in the glue cavity 14.

[0034] Preferably, in one embodiment, the top angle of the tapered barrel wall 122 is between 55° and 65°.

[0035] Optionally, in one embodiment, the heat preservation barrel 10 and the barrel cover 20 are both made of stainless steel. Relying on the excellent thermal conductivity and corrosion resistance of stainless steel, the heat preservation performance and service life of the heat preservation transfer device can be improved.

[0036] Furthermore, if Figure 1 As shown, in one embodiment, the inner barrel body 12 further includes a support portion 123, the support portion 123 is fixedly connected to the lower end of the tapered barrel wall 122 and the outer barrel body 11, the support portion 123 has a mounting cavity 124, the inner barrel body 12 is fixedly connected to the support portion 123, the glue outlet 142 is connected to the mounting cavity 124, and the liquid extraction valve 31 is arranged in the mounting cavity 124. In this way, on the one hand, the support portion 123 can be used to support the inner barrel body 12, and on the other hand, the support portion 123 can be used to install the liquid extraction valve 31, which can effectively utilize the space in the heat preservation barrel 10. In addition, the support portion 123 is located in the heat preservation cavity 13, which can prevent the glue in the liquid extraction valve 31 from solidifying and blocking the liquid extraction valve 31.

[0037] Exemplarily, the liquid extraction valve 31 may be an angle valve.

[0038] Preferably, if Figure 1 As shown, in one embodiment, the liquid taking tube 32 extends from the support portion 123 through the heat preservation chamber 13 to the outside of the outer barrel 11. In this way, when the glue liquid is sampled through the liquid taking tube 32, the heat preservation liquid in the heat preservation chamber 13 can heat and keep the glue liquid in the liquid taking tube 32 to maintain the fluidity of the glue liquid.

[0039] Preferably, if Figure 1 As shown, in one embodiment, the liquid taking component 30 further includes a pipe body flange 33, which is fixed to the outside of the outer barrel 11 and arranged around the liquid taking pipe 32. The pipe body flange 33 can be used to connect the transmission pipeline, and can directly connect the glue outlet 142 to other experimental devices such as a manufacturing device or a spinning device to form an integrated experimental module.

[0040] In particular, if Figure 1 As shown, in one embodiment, the liquid collection component 30 further includes a liquid discharge pipe 34, and the liquid discharge pipe 34 is connected to the liquid collection valve 31. In this way, the glue liquid can flow out from the liquid collection pipe 32 or the liquid discharge pipe 34 through the control of the liquid collection valve 31, so that the glue liquid can be diverted and controlled. The liquid collection pipe 32 and the liquid discharge pipe 34 can be connected to different experimental devices respectively, which is more conducive to the integrated experimental module design.

[0041] Furthermore, if Figure 1 As shown, in one embodiment, the heat preservation transfer device further includes a pressure gauge (not shown), and the barrel cover 20 is provided with a pressure interface 22 connected to the glue liquid chamber 14, and the pressure gauge is arranged on the pressure interface 22. The pressure gauge can detect the pressure in the glue liquid chamber 14, so as to control the pressure of the compressed gas injected into the glue liquid chamber 14 through the pressure in the glue liquid chamber 14 detected by the pressure gauge, so as to prevent the pressure from being too high to cause safety hazards.

[0042] Exemplarily, the pressure gauge may be a vacuum pressure gauge.

[0043] Preferably, if Figure 1 As shown, in one embodiment, the heat preservation transfer device further includes a heat preservation layer 40, which is coated on the outer side of the outer barrel 11 and the barrel cover 20. The heat preservation layer 40 can prevent the heat energy of the heat preservation liquid from being lost too quickly, causing the temperature of the heat preservation liquid to drop, affecting the heat preservation effect; it can also prevent accidental contact with the heat preservation barrel 10, causing burns, and reducing safety hazards.

[0044] Preferably, if Figure 1 As shown, in one embodiment, the heat preservation transfer device further includes a bracket 50, and the bracket 50 is fixedly arranged on the outer side of the outer barrel 11. Such an arrangement facilitates the transportation of the heat preservation transfer device.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
