Technical Field

[0001] The invention relates to the technical field of glass fiber drawing, in particular to a recycling system of a glass fiber sizing agent. Background Art

[0002] Glass fiber has the advantages of high tensile strength, good creep resistance, acid and alkali resistance, and good insulation. It is the preferred high-performance material for environmental protection, military, transportation, IT and other industries. When drawing glass fiber, it is necessary to apply an aqueous emulsion composed of film-forming agent, lubricant, antistatic agent, coupling agent and other ingredients to give the original fiber the required bundling, wear resistance, softness, antistatic requirements and enhance the interface bonding with the composite material. This aqueous emulsion is called a wetting agent.

[0003] The wetting agent is a consumable in the production process, but its production cost is high and it is often not fully utilized and is wasted. Therefore, the recycling of the wetting agent has become an urgent problem that needs to be solved. Summary of the invention

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] After the glass fiber raw yarn or direct yarn is coated and bundled by the oiler, it is wound into a yarn cake by the high-speed rotation of the wire drawing machine. Due to the centrifugal effect of the high-speed rotation, most of the sizing agent on the surface of the raw yarn is thrown out of the yarn cake. This part of the sizing agent can hardly be reused.

[0024] In order to solve this technical problem, Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a recycling system for glass fiber sizing, which includes a collecting container 1, a collecting pipe 2, a first liquid storage container 3, a second liquid storage container 4 and a circulation pipe 5 connected in sequence. The collecting container 1 is used to collect the sizing agent and solid debris thrown out when the wire drawing machine (not shown in the figure) is rotated and wound into a wire cake. The collecting pipe 2 is used to transport the sizing agent collected by the collecting container 1 to the first liquid storage container 3 through a circulation pump (not shown in the figure). The first liquid storage container 3 and the second liquid storage container 4 are connected through a connecting pipe (not shown in the figure). The inlet end of the connecting pipe connected to the first liquid storage container 3 is higher than the outlet end of the connecting pipe connected to the second liquid storage container 4. When the sizing agent reaches the inlet end, the sizing agent flows into the second liquid storage container 4 through the connecting pipe. A first filter (not shown in the figure) is provided at the connection between the collecting pipe 2 and the first liquid storage container 3, and a second filter (not shown in the figure) is provided at the connection between the connecting pipe and the second liquid storage container 4. The mesh number of the second filter is greater than the mesh number of the first filter. The sizing agent in the second liquid storage container 4 is recycled through the circulation pipe 5.

[0025] In this embodiment, by providing a collection container 1, a collection tube 2, a first liquid storage container 3, a second liquid storage container 4 and a circulation tube 5 which are connected in sequence, the functions of collection, separation, filtration and recycling can be realized, thereby realizing the recycling of most of the wetting agent, reducing the oil consumption of the raw yarn, promoting green production and improving efficiency.

[0026] In addition, by retaining the solid debris in the collection container 1 and filtering the wetting agent through the first filter and the second filter in sequence, three-stage filtration of the wetting agent is achieved, thereby ensuring the recovery quality of the wetting agent.

[0027] In some embodiments, the first liquid storage container 3 and the second liquid storage container 4 are both provided with heat preservation and heating devices (not shown in the figure), so as to achieve the effect of cooling the infiltrant in summer and heating it in winter.

[0028] In one embodiment of the present invention, the collecting container 1 is formed by a front plate (not shown in the figure, the front plate is hidden due to the sectional view), a rear plate 11, an upper plate 12, a lower plate 13 and a side plate 14. The upper plate 12 is provided with a notch 121 for allowing glass fiber drawing to pass through. The drawing machine is fixed to the rear plate 11. The lower plate 13 is provided with a reflux groove 131, and the reflux groove 131 is connected to the collecting pipe 2.

[0029] In one embodiment of the present invention, the side plate 14 connected to the lower plate 13 is tilted, which is conducive to the infiltrant flowing into the reflux groove 131, while solid debris (such as solid hairy fibers and thick fibers) are retained on the lower plate 13.

[0030] In some embodiments, the width of the lower plate 13 may be 250 to 900 mm, and the length and width may be designed according to the head, operating radius, and wire arrangement mechanism of the wire drawing machine.

[0031] In one embodiment of the present invention, the lower plate 13 is provided with a baffle (not shown in the figure), which is provided at the outer periphery of the reflux groove 131, and is used to prevent solid debris from entering the reflux groove 131. When the liquid level of the infiltrant is higher than the baffle, the infiltrant flows into the reflux groove 131, so that the infiltrant can be initially purified.

[0032] In one embodiment of the present invention, the enclosure is provided with a plurality of through holes (not shown in the figure), and the through holes are used to allow the wetting agent to pass through but prevent the solid debris from passing through.

[0033] In one embodiment of the present invention, the height of the enclosure does not exceed 5 mm.

[0034] In one embodiment of the present invention, the reflux groove 131 is funnel-shaped, with the largest cross-sectional area of ​​the reflux groove 131 facing the collection container 1, and the smallest cross-sectional area of ​​the reflux groove 131 facing the collection tube 2. This arrangement is conducive to achieving the reflux of the infiltrant.

[0035] In one embodiment of the present invention, the mesh sizes of the first filter and the second filter are both no greater than 200 meshes.

[0036] It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements defined by the statement "comprise one..." do not exclude the existence of other identical factors in the process, method, article or equipment including the elements.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, and is not used to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
