Description

Technical Field

[0001] The utility model relates to the technical field of spinning equipment, in particular to a sealing device for a spinning box. Background Art

[0002] In the traditional spinning process, the filaments ejected from the spinneret enter the cooling water tank for rapid cooling, and then enter the post-spinning equipment for drying and solvent gas recovery. In the flash evaporation route currently developed, the filaments in the spinning manifold enter the spinning tunnel after exiting the spinneret. The solvent is rapidly vaporized in a high temperature environment, and most of the gas will be recycled through the recovery system. Another part of the gas will enter the spinning manifold and diffuse into the air outside the equipment, which not only consumes a lot of energy and increases operating costs, but also pollutes the working air environment. Therefore, reasonable measures need to be taken to solve the problem of gas leakage in order to achieve the goal of energy saving, consumption reduction, and green environmental protection. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a sealing device for a spinning manifold; the sealing device cooperates with the spinning manifold to effectively control the leakage of solvent gas, realize efficient recovery of solvent, save equipment investment and operating costs, and is green and environmentally friendly.

[0004] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0005] A sealing device for a spinning box, wherein a component box is provided in the spinning box, and a spinning component is provided in the component box; the sealing device is sealingly installed in the space above the component box of the spinning box to control the escape of gas generated during the spinning process; the sealing device comprises a sealing shell and a sealing strip, wherein the sealing shell is filled with a heat-insulating material, and a sealing strip is provided at the bottom of the sealing shell; the sealing strip is in contact with and pressed against the component box.

[0006] Furthermore, the top surface of the component box is a planar structure, and the sealing strip in the sealing device is in contact and pressed against the top surface of the component box.

[0007] Furthermore, the sealed shell is a cubic box made of stainless steel.

[0008] Furthermore, sealing strips are provided around the bottom of the sealing shell.

[0009] Furthermore, the sealing strip has a sealing portion and a connecting portion, the sealing portion of the sealing strip has a hollow circular cross-section, and the connecting portion of the sealing strip is a planar structure connected to the sealing portion; the connecting portion of the sealing strip is fixedly connected to the sealing housing. The sealing strip with a hollow circular structure deforms when it is sealed and pressed against the component housing, thereby achieving a better sealing effect.

[0010] Furthermore, a handle is provided on the top of the sealing shell to facilitate installation of the sealing device in the sealing box.

[0011] The beneficial effects of the utility model are:

[0012] The sealing device of the utility model is sealed and pressed against the component box, and the sealing strip in the sealing device utilizes its deformation generated during pressing to completely contact and press against the top surface of the component box, thereby achieving a relatively excellent sealing effect; when the spinning box is working, the fiber bundle enters the subsequent spinning tunnel through the spinneret in the spinning assembly, and the high-temperature hot air in the tunnel causes the solvent on the fiber to vaporize rapidly, and most of the gas enters the gas recovery system through the tunnel, while a small amount of gas passing through the gap between the spinning assembly and the component box will not escape to the outside of the spinning box due to the relatively excellent sealing effect of the sealing device, thereby effectively controlling the solvent gas from diffusing outwards, and on the contrary, it can be recycled and reused through the spinning tunnel.

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] In the description of the present invention, it should be understood that the terms "front", "rear", "left", "right", "up", "down", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] like Figure 1 and Figure 2 A sealing device for a spinning box is shown; wherein, a component box 2 is provided in the spinning box 1, and a spinning component 3 is provided in the component box 2; the spinning component 3 includes a distribution plate, a spinneret, etc., which is a well-known technology and is not described here; the sealing device 4 is sealed and installed in the space above the component box 2 of the spinning box 1 to control the escape of gas generated during the spinning process; specifically, the sealing device 4 includes a sealing shell 41 and a sealing strip 42, the sealing shell 41 is filled with a heat-insulating material 43, and the bottom of the sealing shell 41 is provided with a sealing strip 42; the top surface of the component box 2 is a planar structure, and the sealing strip 42 in the sealing device 4 is in contact and pressed against the top surface of the component box 2.

[0020] The sealing shell 41 is a cubic box made of stainless steel, and the inner cavity of the cubic box is filled with a heat-insulating material 43. The heat-insulating material 43 can make the sealing device 4 have a certain heat-insulating effect while sealing.

[0021] In order to further improve the sealing effect, sealing strips 42 are provided around the bottom of the sealing housing 41 .

[0022] More specifically, the sealing strip 42 has a sealing portion 421 and a connecting portion 422. The cross section of the sealing portion 421 of the sealing strip 42 is a hollow circular structure, and the connecting portion 422 of the sealing strip 42 is a planar structure connected to the sealing portion 421; the connecting portion 422 of the sealing strip 42 is fixedly connected to the sealing housing 41. The sealing strip 42 of the hollow circular structure will deform when it is sealed and pressed against the component box 2, thereby achieving a better sealing effect. The sealing strip 42 is made of a high temperature resistant and oil resistant material.

[0023] like Figure 2 As shown, a handle 44 may be provided at the top center of the sealing shell 41; the handle 44 may also be provided as a rotatable structure to facilitate its pulling up and retracting; during installation, the sealing device 4 may be conveniently installed in the spinning box 1 through the handle 44.

[0024] Before spinning, the spinning assembly 3 is first placed in the assembly box 2 in the spinning manifold 1; then the heat-insulating aluminum block 5 is placed in the space above the spinning assembly 3 of the assembly box 2, and then the sealing device 4 is placed, and the sealing strip 42 therein is pressed against the top surface of the assembly box 2, and then the heat-insulating cover 6 is installed in place, and the heat-insulating cover 6 is arranged in the space above the sealing device 4 of the spinning manifold 1, and it is supported on the spinning manifold 1. The spinning tunnel 7 located below the bottom plate 11 of the spinning manifold 1 is raised, so that the sealing member 8 at the top of the spinning tunnel 7 is completely pressed against the bottom plate 11 of the spinning manifold 1. When the spinning box 1 is working, the fiber bundle enters the spinning tunnel 7 through the spinneret 31. The high-temperature hot air in the tunnel causes the solvent on the fiber to vaporize rapidly, and most of the gas enters the gas recovery system through the tunnel. The solvent gas passing through the gap between the spinning assembly 3 and the assembly box 2 will not escape to the outside of the spinning box 1 due to the excellent sealing effect of the sealing device 4, thereby effectively controlling the solvent gas from diffusing outward. Instead, the solvent gas can be recycled through the spinning tunnel 7.

[0025] According to the experimental data analysis, after adding the sealing device, the volatilization of solvent gas was reduced from the original 35%-40% to 5%, and the solvent recovery rate reached 95%, which greatly saved the operating cost and improved the solvent recovery rate.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
