Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber drawing equipment, in particular to a leaking plate for glass fiber drawing production. Background Art

[0002] At present, the production process of glass fiber precursor is mostly as follows: after the raw materials are melted in a pool furnace to form glass liquid, they are transported through the material channel and flow into the drawing plate through the flow hole. The temperature of the glass liquid is adjusted again by the plate, and then they are divided into a certain number of strands according to different needs, and then they are wound at high speed by a wire drawing machine to form precursor.

[0003] The existing glass fiber drawing leak plate adopts a material taking filter screen whose size is the same as the flow hole size, larger than the flow hole size, or smaller than the flow hole size, and the height of the material taking filter screen is lower than the flange. Therefore, no matter which filter screen size is adopted, the glass liquid flowing out of the flow hole will all flow into the leak plate forming area and be drawn through the leak plate; in the actual production process, after the glass liquid is melted by the pool furnace and flows into the leak plate, it must be transported through the material channel and the flow hole section. During this transportation process, the glass liquid will corrode and wash the refractory materials of the material channel and the flow hole, and bring the corroded and washed refractory materials and other foreign materials into the glass liquid. During the flow of the glass liquid, these corroded and washed refractory materials and foreign materials will gradually sink to the bottom and flow slowly due to their large specific gravity, and will eventually flow into the leak plate along the wall of the flow hole. These substances and foreign materials will cause uneven fiber diameter and breakage in the drawing process, thereby interrupting continuous production, affecting the instability of product quality and the improvement of production efficiency.

[0004] In the current leak plate design, the material taking method adopted cannot prevent the bad glass liquid containing impurities and foreign matter from flowing into the leak plate. Therefore, in actual production, it is inevitably affected by these factors, and it is impossible to further stabilize product quality and improve production efficiency. Utility Model Content

[0026] Example 1

[0027] like Figure 1-Figure 4 As shown:

[0028] A leaking plate for glass fiber drawing production comprises a bottom plate 1, a material taking channel 2 is installed on the bottom plate 1, and a sewage discharge channel 3 installed on the bottom plate 1 is arranged outside the material taking channel 2.

[0029] The material taking channel 2 is a frustum-shaped structure, and the material taking channel 2 includes a material taking filter screen 21 . The material taking filter screen 21 and the bottom plate 1 are connected via a dirt baffle plate 22 , and the dirt baffle plate 22 is arranged at an angle.

[0030] The sewage channel 3 includes a side plate 32 installed on the side and a flange 31 installed on the top. The top of the side plate 32 is connected to the flange 31 , and the bottom of the side plate 32 is connected to the side edge of the bottom plate 1 .

[0031] The height of the material taking filter screen 21 is higher than the height of the flange 31 .

[0032] The material taking filter screen 21 is coaxially arranged with the liquid flow hole, and the area of ​​the material taking filter screen 21 is smaller than that of the liquid flow hole, so as to prevent the bad glass liquid flowing down the liquid flow hole wall from entering the material taking channel 2 of the effective wire drawing forming area of ​​the leak plate.

[0033] The material taking filter screen 21 extends upward to the inside of the liquid flow hole to prevent bad glass liquid from accumulating near the flange 31 and then flowing into the material taking channel 2 again, causing secondary contamination of the glass in the effective wire drawing forming area.

[0034] The bad glass liquid is guided to flow to the two end areas of the leak plate that do not affect production through the sewage channel 3, so as to prevent the bad glass liquid from accumulating in the flow hole for a long time and still flowing into the material collection channel 2 after exceeding the height of the material collection filter screen 21.

[0035] A production nozzle 23 is installed on the bottom plate 1 located in the material taking channel 2.

[0036] A sewage discharge nozzle 33 is installed on the bottom plate 1 between the dirt baffle plate 22 and the side plate 32 to prevent the accumulation of liquid in the drain plate and the flow hole, and to avoid excessive accumulation for a long time exceeding the height of the material filter screen 21.

[0037] The outside of the side plate 32 is equipped with an electrode 4, which is energized to heat the leak plate, so that the temperature of the glass liquid is adjusted again, and then the glass liquid flows out in a certain number according to different needs.

[0038] The leak plate flange 31 is installed tightly against the lower edge of the flow hole brick, and the part of the material taking filter 21 that is higher than the leak plate flange 31 extends into the flow hole. The glass liquid passing through the material taking filter 21 is the middle part of the flow hole that is not attached to the wall of the flow hole, while the bad glass liquid that flows down along the walls of the flow hole on all sides flows into the sewage discharge channel 3 at both ends of the leak plate, and then is discharged through the sewage discharge nozzle 33.

[0039] The utility model has a simple and compact structure, avoids unstable quality products caused by erosion and scouring of refractory materials in the material channel and the flow hole by molten glass, prevents uneven fiber diameter and breakage during the wire drawing process, and improves product quality and production efficiency.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
