Abstract
Description
Technical Field
[0001] This utility model relates to the field of basalt fiber production, and more specifically, to an impregnation tank for basalt fiber production. Background Technology
[0002] Basalt fiber is a continuous fiber made by melting basalt rock at 1450℃~1500℃ and then drawing it at high speed through a platinum or platinum-rhodium alloy spinneret. Its strength is comparable to high-strength S-glass fiber. Pure natural basalt fiber is generally brown in color, sometimes resembling gold. Basalt fiber is a new type of inorganic, environmentally friendly, high-performance fiber material. It is made by rapidly drawing basalt rock, composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide, and titanium dioxide, through a spinneret after high-temperature melting.
[0003] Existing basalt fiber composite material production lines, such as Figure 1 The production line includes, in sequence, a basalt fiber yarn rack 1, a tension rack 2, an impregnation tank 3, a drying device 4, a traction machine 5, and a pelletizer 6. The impregnation tank 3, for example... Figure 2 The impregnation tank 3 includes a glue tank body 12, which contains glue 13. Basalt fiber 7 comes out of the basalt fiber yarn frame 1, passes through the tension frame 2, and is turned by the first inclined steering wheel 8 before entering the glue 13. Then, it is turned horizontally by the first horizontal steering wheel 10 and moves forward in the glue 13. The basalt fiber 7 is impregnated in the glue 13 and coated by the glue 13. When it moves to the second horizontal steering wheel 11, it turns, then leaves the glue, and is turned by the second inclined steering wheel 9 before entering the drying equipment 4 for drying. Then it enters the traction machine 5, and finally the pelletizer 6 cuts the coated basalt fiber to the length required by the customer, completing the production of basalt fiber composite material.
[0004] Because basalt fiber 7 inevitably carries away some adhesive solution as it enters and exits the impregnation tank 3, the adhesive solution in the impregnation tank 3 gradually decreases. Currently, replenishing the adhesive solution in the impregnation tank 3 when insufficient is done manually. When workers notice the adhesive level is low, they add adhesive, but sometimes too much is added, causing it to overflow from the impregnation tank 3 and pollute the environment. More importantly, if workers do not notice the insufficient adhesive level, the basalt fiber 7 may leave the impregnation tank 3 without being impregnated, resulting in quality problems.

A spray head assembly connected to the glue storage tank through a feed pipe is provided at the bottom of the glue tank body. A feed pump and a distributor are installed on the feed pipe.

[0029] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0030] Example 1
[0031] Please refer to Figures 3-6 , Figure 3 This is a schematic diagram of a basalt fiber composite material production line provided in this embodiment. Figure 4 This is a schematic diagram of the impregnation tank structure provided in this embodiment. Figure 5 This is a schematic diagram of the vortex flow forming plate structure of this utility model. Figure 6 This is a schematic diagram of the bent pipe structure of this utility model.
[0032] A basalt fiber composite material production line includes a basalt fiber yarn rack 1, a tension rack 2, an impregnation tank 3, a drying device 4, a traction machine 5, and a pelletizer 6 arranged in sequence. A first inclined steering wheel 8 is provided between the tension rack 2 and the impregnation tank 3. A first horizontal steering wheel 10 and a second horizontal steering wheel 11 are provided inside the impregnation tank 3. The line connecting the first horizontal steering wheel 10 and the second horizontal steering wheel 11 is a horizontal line 14. A second inclined steering wheel 9 is provided between the impregnation tank 3 and the drying device 4. The impregnation tank 3 includes a glue tank body 12 and a glue storage tank 17 located outside the glue tank body 12. A spray head assembly 20 is provided at the bottom of the glue tank body 12 and is connected to the glue storage tank 17 through a feed pipe 21. A feed pump 22 and a distributor 23 are installed on the feed pipe 21. The distributor 23 is a commercially available liquid distributor.
[0033] When the amount of adhesive 13 in the dipping tank 3 is low, adhesive is added from the bottom to the adhesive tank body 12 through the feed pipe 21. The spray head assembly 20 is installed at the bottom of the adhesive tank body 12. When adding liquid, the adhesive 13 sprayed upward causes the adhesive 13 in the dipping tank 3 to move, so that the adhesive 13 is more uniform.
[0034] Those skilled in the art should know that, in one or more specific embodiments of the present invention, the impregnation tank 3 further includes a return pipe 18, which is connected to the adhesive storage tank 17. A valve 19 is installed on the return pipe 18. A low liquid level sensor 15 and a high liquid level sensor 16 are provided on the tank wall of the adhesive tank body 12. The low liquid level sensor 15 is located above the horizontal line 14, and the high liquid level sensor 16 is located above the low liquid level sensor 15.
[0035] When the high-level sensor 16 senses the liquid level, the machine alarms (alarm devices are not shown in the diagram; those skilled in the art can purchase them commercially). On-site inspection of the liquid level is necessary to confirm the cause of any abnormal rise and take appropriate action. If the liquid level has not yet been reached, the liquid level sensor 15 senses the liquid level and the machine alarms, and valve 19 closes to ensure the pipeline and tank are full. When the liquid level in the tank reaches the high-level sensor 16, valve 19 opens. The installation of the high-level sensor 16 and the low-level sensor 15 further ensures stable production.
[0036] Those skilled in the art should know that, in one or more specific embodiments of this utility model, the impregnation tank 3 further includes an overflow pipe 24, and an overflow port 25 is provided on the tank wall of the adhesive tank body 12. The overflow port 25 is located above the high liquid level sensor 16, and the other end of the overflow pipe 24 is connected to the adhesive storage tank 17. In extreme conditions, when the adhesive 13 reaches the overflow port 25, it flows out from the overflow port 25 back to the adhesive storage tank 17, thus avoiding an accident.
[0037] Those skilled in the art should understand that, in one or more specific embodiments of this utility model, a vortex flow forming plate 26 is installed above the spray head assembly 20. The vortex flow forming plate 26 includes a base plate 27, on which homogenizing units 28 are arranged in an array. Each homogenizing unit 28 consists of three or more bends 29 with different outflow directions. Each bend 29 consists of a vertical pipe 30 and a horizontal pipe 31, with the vertical pipe 30 passing through the base plate 27. Those skilled in the art should understand that they can use existing methods to install the vortex flow forming plate 26 onto the wall of the adhesive tank body 12, such as through interlocking connections or welding.
[0038] By setting up a vortex flow forming plate 26 and installing a homogenization unit 28 on the vortex flow forming plate 26, the adhesive 13 is sprayed upward after entering the adhesive tank body 12 through the spray head assembly 20. The vortex flow forming plate 26 disperses the adhesive 13 in all directions in the tank. The flow of the adhesive 13 drives the adhesive 13 in the tank to form a vortex flow dispersion similar to stirring, thereby achieving the purpose of uniform dispersion of the adhesive 13 and improving the uniformity of the product.
[0039] Those skilled in the art should know that in one or more specific embodiments of this utility model, the substrate 27 can be a metal plate or a plastic tube, with a plastic tube being preferred.
[0040] Those skilled in the art should know that the homogenization unit 28 consists of four bends 29 with different outflow directions. At this time, the horizontal pipes 31 of the four bends 29 face four directions and flow out from four directions.
