TECHNICAL FIELD

[0002] In industrial production, many scenes need to carry out heat preservation treatment to some working parts. For example, in the textile field, the spinneret or filter needs a constant temperature working environment. Taking the spinneret as an example, the main function of the spinneret is to extrude the high polymer melt or solution in a viscous state through micropores to form a filament. If the temperature of the spinneret is too low, the high-temperature melt may be cooled and solidified in the spinneret hole, causing the spinneret hole to be blocked, and then the filament breaks, affecting the continuity of production and product quality, and reducing production efficiency. For example, in the production of polyester staple fiber, heat preservation is needed to ensure smooth production.
[0003] The existing spinneret heat preservation measures have many defects, such as the electric heating wire method needs to wind the electric heating wire around the spinneret or install it near the spinneret, or the heating rod method needs to insert the heating rod into a position in close contact or close proximity with the spinneret, but all have the problem of uneven heating area. The middle area of the spinneret has relatively good heat preservation performance, and the temperature difference is small, while the temperature difference of the surrounding frame is large. The traditional heat preservation method is not easy to adapt to the particularity of the temperature difference of the spinneret in different places, and it is not easy to ensure the uniformity of the temperature of the spinneret in different places. It also needs to adjust the temperature value of the electric heating wire in different areas to achieve it, which is complex and cumbersome.
[0004] In view of the above problems, the existing technology has not solved the problem well, which has brought trouble to the normal work in the field, therefore, a novel pipeline heat preservation structure is needed to solve the above problems. UTILITY MODEL CONTENTS

[0030] Reference Figures 1-4 For the first embodiment of the utility model, a new type of pipeline heat preservation structure is proposed, which is configured beside the component to be preserved, including support 1, outer heat preservation pipe 2 and intermediate heat preservation pipe 3, the outer heat preservation pipe 2 and the intermediate heat preservation pipe 3 are arranged on the support 1, the outer heat preservation pipe 2 has an inlet 4, the intermediate heat preservation pipe 3 has an outlet 5, the outer heat preservation pipe 2 is arranged around the edge direction of the component to be preserved, the intermediate heat preservation pipe 3 is located at the middle position of the component to be preserved, the outer heat preservation pipe 2 is communicated with the intermediate heat preservation pipe 3, which is used to make the heat preservation medium flow from the outer heat preservation pipe 2 to the intermediate heat preservation pipe 3.
[0031] In this embodiment, in order to ensure the uniformity of the temperature of the component to be preserved, a special pipeline heat preservation structure is designed, and heat preservation medium (such as water or oil) is passed in the pipe. Specifically, the outer heat preservation pipe 2 is arranged around the component to be preserved (such as spinneret), the intermediate heat preservation pipe 3 is arranged in the middle area of the component to be preserved, the inlet 4 is designed on the outer heat preservation pipe 2, the outlet 5 is arranged on the intermediate heat preservation pipe 3, and the water outlet end of the outer heat preservation pipe 2 is communicated with the water inlet end of the intermediate heat preservation pipe 3, so that the heat preservation medium can flow in the outer heat preservation pipe 2 first, and then enter the intermediate heat preservation pipe 3 after flowing to the tail end of the outer heat preservation pipe 2, and finally flow out from the outlet 5, realizing circulation.
[0032] In the initial stage of the heat preservation medium flowing into the outer heat preservation pipe 2, the temperature is relatively high, and since the outer heat preservation pipe 2 is arranged around the edge of the component to be preserved, the temperature difference of the position around the component to be preserved can be preferentially ensured. With the continuous heat exchange in the flowing process, the temperature of the heat preservation medium is continuously reduced, and then flows into the intermediate heat preservation pipe 3, and then exchanges heat with the position with a relatively small temperature difference in the middle of the component to be preserved, so as to ensure the uniformity of the overall temperature of the component to be preserved. When the component to be preserved is a spinneret, the temperature fluctuation of the spinneret as a whole can be ensured to be very small, and the high polymer melt or solution in the internal viscous flow state has good flowability and uniformity, so that the extruded filaments are more uniform in diameter, shape and other aspects, which is beneficial to improve the quality and performance of the product and meet the requirements of the production process.
[0033] Further, the outer heat preservation pipe 2 is two, the intermediate heat preservation pipe 3 is one, the intermediate heat preservation pipe 3 is located between the two outer heat preservation pipes 2, and further comprising a tail end pipe 6, the tail end pipe 6 is communicated at both ends to the tail end of the two outer heat preservation pipes 2, and the middle part of the tail end pipe 6 is communicated to the end of the intermediate heat preservation pipe 3.
[0034] In this embodiment, the intermediate heat preservation pipe 3 is located between the two outer heat preservation pipes 2 and is arranged in parallel, which ensures the rationality of the structure. The tail end of the outer heat preservation pipe 2 is also designed with a tail end pipe 6, which serves to connect the outer heat preservation pipe 2 and the intermediate heat preservation pipe 3. The tail end pipe 6 is communicated at both ends to the tail end of the two outer heat preservation pipes 2, and the middle part is communicated to the end of the intermediate heat preservation pipe 3. The tail end pipe 6 can ensure that the heat preservation medium fully flows to the end in the outer heat preservation pipe 2 and then enters the intermediate heat preservation pipe 3, so as to ensure that the heat preservation medium can fully exchange heat with the edge position of the component to be preserved when the temperature is relatively high, and improve the uniformity of the overall heat preservation.
[0035] Further, the outer heat preservation pipe 2 and the intermediate heat preservation pipe 3 are both in a bent shape.
[0036] In this embodiment, the outer heat preservation pipe 2 and the intermediate heat preservation pipe 3 are designed in a bent shape, so that the overall shape is similar to a fan shape, which can better adapt to the fan-shaped arrangement of the spinneret structure.
[0037] Further, the bent part of the intermediate heat preservation pipe 3 is communicated by means of a connecting pipe group, the connecting pipe group comprising a connecting section one 7, a connecting section two 8 and a connecting section three 9, the middle parts of the connecting section one 7 and the connecting section two 8 are respectively communicated with two sections of the intermediate heat preservation pipe 3, the connecting section three 9 is communicated at both ends with the connecting section one 7 and the connecting section two 8, and the connecting section three 9 is at least two sections.
[0038] In this embodiment, the intermediate heat preservation pipe 3 is divided into two sections by the bending point, and the two sections are connected by the connecting pipe group. Specifically, the heat preservation medium flows into the connecting section one 7 in the first section of the intermediate heat preservation pipe 3, then flows into the connecting section three 9, and then flows into the connecting section two 8, and then flows into the connecting section two of the intermediate heat preservation pipe 3, so as to realize the transportation of the heat preservation medium.
[0039] Because the bending part of the intermediate heat preservation pipe 3 is the boundary of the two groups of components to be heat preserved, and the connecting section one 7 and the connecting section two 8 in the connecting pipe group can guide the heat preservation medium to the two sides in this embodiment, so that the heat preservation medium can fully exchange heat with the side edges of the two groups of components to be heat preserved, and the overall uniformity of the heat preservation effect is guaranteed.
[0040] Further, the two ends of the connecting section one 7 and the connecting section two 8 are respectively connected to the outer heat preservation pipes 2 on both sides, and the connecting section one 7 and the connecting section two 8 are not connected to the outer heat preservation pipes 2.
[0041] In this embodiment, the two ends of the connecting section one 7 and the connecting section two 8 are respectively connected to the outer heat preservation pipes 2 on both sides, which can play a supporting role, thereby improving the strength and stability of the overall pipeline structure. The connecting section one 7, the connecting section two 8 and the outer heat preservation pipe 2 are connected by welding, and the two are not connected, so as to ensure that the heat preservation medium fully flows to the end in the outer heat preservation pipe 2 and then enters the intermediate heat preservation pipe 3.
[0042] Further, it further comprises a connecting rod 10, and the two ends of the connecting rod 10 are respectively connected to the outer heat preservation pipe 2 and the intermediate heat preservation pipe 3, and the connecting rod 10 is a plurality of connecting rods.
[0043] In this embodiment, the two ends of the connecting rod 10 are respectively connected to the outer heat preservation pipe 2 and the intermediate heat preservation pipe 3, and the connecting rod 10 is designed to have a plurality of connecting rods, and the plurality of connecting rods 10 are parallel to each other, which can play a supporting role, so that the overall pipeline heat preservation structure is more stable, and the problem of poor structural stability caused by the length of the outer heat preservation pipe 2 and the inner heat preservation pipe is avoided.
[0044] Further, the new pipeline heat preservation structure is symmetrically provided with two groups.
[0045] In this embodiment, the new pipeline heat preservation structure is symmetrically provided with two groups, because the outer heat preservation pipe 2 and the intermediate heat preservation pipe 3 are both bent, so that the area of the fan-shaped arrangement can be increased after the new pipeline heat preservation structure is symmetrically arranged, and because the overall structure has only one circle of pipeline, compared with the traditional heating and heat preservation method, the volume is greatly reduced, the requirement for installation space is small, more spinnerets can be installed, and the installation adaptability of the new pipeline heat preservation structure is improved.
[0046] Further, the water inlet pipe 11 is provided, which is n-shaped, and both ends of the water inlet pipe 11 are communicated with the outer heat preservation pipe 2, and the inlet 4 is arranged on the water inlet pipe 11.
[0047] In the embodiment, the water inlet pipe 11 is n-shaped, and both ends of the water inlet pipe 11 are communicated with the outer heat preservation pipe 2, and the inlet 4 is arranged on the water inlet pipe 11, when the circulating heat preservation medium, the heat preservation medium enters the water inlet pipe 11 through the inlet 4, and then is delivered into the outer heat preservation pipe 2 at both ends of the water inlet pipe 11, so that the uniformity of the flow rate and flow of the heat preservation medium in the outer heat preservation pipe 2 can be ensured, and the uniformity of the overall heat preservation of the component to be preserved can be improved.
[0048] Further, the support 1 is provided with a mounting hole 12.

The outer heat preservation pipe 2, the intermediate heat preservation pipe 3, the tail pipe 6 and the connecting pipe group are all rectangular pipes, and a plurality of pipes are connected by welding, so as to ensure the sealing of the connection and avoid leakage, and to ensure the structural strength of the overall heat preservation structure.
[0051] It should be noted that the above embodiments are only used to illustrate the technical scheme of the utility model and not to limit, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical scheme of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical scheme of the utility model, and all should be covered in the scope of the claims of the utility model.
