Abstract
Description
Technical Field
[0001] This utility model relates to the field of barium sulfate production technology, and in particular to a barium sulfate microreactor for chemical fibers. Background Technology
[0002] Barium sulfate is used in the production of synthetic fibers to improve fiber performance. However, barium sulfate requires a specialized reaction apparatus, which has some defects and shortcomings. Specific areas for improvement are as follows: 1. The conventional method of producing barium sulfate involves mixing sulfuric acid and barium hydroxide to produce barium sulfate precipitate and water. However, this reaction requires constant stirring, which increases labor costs. Furthermore, sulfuric acid and barium hydroxide are acidic and alkaline solutions, respectively, making manual stirring dangerous. 2. After production, barium sulfate needs to be dried. Conventional drying equipment is often inconveniently located, leading to uneven drying of the barium sulfate inside the reaction tank. Therefore, we propose a micro-reaction apparatus for barium sulfate used in synthetic fibers. Utility Model Content

[0008] Preferably, the reaction vessel is located inside the limiting ring, the limiting ring is located inside two sets of limiting rings, and several sets of moving rollers are in contact with the limiting ring but not fixed.
[0009] By adopting the above technical solution, the movable roller can facilitate the rotation of the reaction tank, which is located above several sets of nozzles.

[0015] By adopting the above technical solution, the snap-fit teeth and snap-fit gears can be engaged and locked together, which can drive the reaction tank to rotate.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. By setting up a stirring mechanism, a spiral stirring blade is fixedly connected to the extension rod of the stirring structure via a connecting rod. This can stir and mix the sulfuric acid and barium hydroxide solution inside, facilitating their reaction to produce barium sulfate.

[0027] Please see Figure 1-4This utility model provides a technical solution:
[0028] A barium sulfate microreactor for chemical fibers includes four sets of support legs 1. A limiting ring 2 is fixedly connected to the middle of the upper part of the four sets of support legs 1. A motor 3 is fixedly connected to the upper part of the support leg 1 on the front right side. A snap-fit gear 4 is fixedly connected to the output end of the motor 3. A rectangular plate 5 is fixedly connected to the lower part of the two sets of support legs 1 on the front left and rear right sides. A gas storage pipe 6 is fixedly connected to the middle of the upper part of the rectangular plate 5. Several sets of nozzles 7 are fixedly connected at equal intervals to the upper part of the gas storage pipe 6. A vent pipe 8 is fixedly connected to the left end of the gas storage pipe 6. A stirring mechanism 9 is fixedly connected to the upper part of the two sets of support legs 1 on the front left and rear right sides. A reaction mechanism 10 is movably snap-fitted inside the limiting ring 2.
[0029] In this embodiment, the reaction mechanism 10 includes a reaction tank 11. Two sets of limiting rings 12 are fixedly connected to the upper outer surface of the reaction tank 11. Several sets of movable rollers 13 are movably connected to the near ends of the two sets of limiting rings 12 through a U-shaped rod at equal intervals. Several sets of snap-fit teeth 14 are fixedly connected at equal intervals to the upper outer surface of the reaction tank 11. Drain pipes 15 are fixedly connected to the lower left and lower right ends of the reaction tank 11. A filter screen 16 is fixedly connected inside the drain pipe 15 on the right side. The reaction tank 11 is located inside the limiting ring 2. The limiting ring 2 is located inside the two sets of limiting rings 12, and the several sets of movable rollers 13 are in contact with the limiting ring 2 but are not fixed.
[0030] Through the above scheme: the upper part of the reaction tank 11 is fixedly connected with a snap-fit protrusion 14, which meshes with the snap-fit gear 4 at the output end of the motor 3, so as to drive the reaction tank 11 to rotate, so that the flame sprayed from the nozzle 7 at the bottom can evenly heat the lower part of the reaction tank 11 and evenly dry the barium sulfate inside.
[0031] In this embodiment, the stirring mechanism 9 includes a support frame 91. An extension tube 92 is fixedly connected to the middle of the lower inner wall of the support frame 91. An extension rod 93 is inserted and fixedly arranged in the middle of the support frame 91. Several sets of connecting rods 94 are fixedly connected at equal intervals on the outer surface of the extension rod 93. The ends of the several sets of connecting rods 94 that do not contact the extension rod 93 are fixedly connected to a stirring blade 95. The lower left and lower right ends of the extension rod 93 are both fixedly connected to a scraping plate 96. The stirring blade 95 and the scraping plate 96 are both located inside the reaction tank 11. The scraping plate 96 contacts the lower inner wall of the reaction tank 11 but is not fixed. Several sets of snap-fit teeth 14 are fixedly connected to the support leg 1 and are engaged with the snap-fit gear 4.
[0032] With the above scheme: the extended round rod 93 on the stirring mechanism 9 has a stirring blade 95 fixedly connected by a connecting rod 94. The extended round rod 93 and the stirring blade 95 are stationary, but the reaction tank 11 is driven to rotate, so the internal contents can be stirred. In addition, during the subsequent drying, the scraping plate 96 at the bottom can scrape the inner wall of the reaction tank 11 to prevent barium sulfate from sticking to the inner wall.
[0033] It should be noted that this utility model is a barium sulfate microreactor for chemical fibers. During use, a proportioned sulfuric acid solution and barium hydroxide solution are first injected into the reaction tank 11. Then, the motor 3 is driven. The output end of the motor 3 is fixedly connected to a snap-fit gear 4, which engages with a snap-fit protrusion 14 fixedly connected to the upper outer surface of the reaction tank 11. This allows the reaction tank 11 to rotate. Furthermore, a movable roller 13, movably connected to a limiting ring 12 fixedly connected to the outer surface of the reaction tank 11 via a U-shaped rod, reduces friction during the rotation of the reaction tank 11, facilitating its rotation. The upper part of the support leg 1 is fixed... The connecting rod 94 and stirring blade 95, which are connected by the extension rod 93, are fixed on the support frame 91. When the reaction tank 11 rotates, the solution inside is mixed and stirred to facilitate the reaction. After the reaction is completed, the solution inside is discharged through the drain pipe 15 with a filter screen 16, leaving only moist barium sulfate inside the reaction tank 11. As the reaction tank 11 continues to rotate, the gas pipe 8 at the bottom is supplied with gas, which is sprayed out from the nozzle 7. The gas is ignited and heats the lower end of the reaction tank 11 evenly, which facilitates the drying of barium sulfate. The scraping plate 96 can scrape the inner wall of the reaction tank 11 to prevent barium sulfate from sticking together.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
