[0026] Example

[0027] Depend on Figure 1-4 A distillation tower with a quantitative feeding function is provided, comprising a distillation tower body 1 and a feeding pipe 2;

[0028] The feeding pipe 2 is arranged at the upper end of the distillation tower body 1 and is connected to the distillation tower body 1;

[0029] An inner tube 21 is provided in the feeding tube 2, and two sets of adjustment components 3 are installed on the inner wall of the feeding tube 2. The adjustment components 3 include two screw boxes 31 installed in the feeding tube 2, and an adjustment plate 35 is slidably arranged between the two screw boxes 31;

[0030] An upper positioning plate 4 and a lower positioning plate 5 are installed between the two screw boxes 31, and there is a gap between the upper positioning plate 4 and the lower positioning plate 5, and the adjustment plate 35 slides between the upper positioning plate 4 and the lower positioning plate 5;

[0031] A hole is provided between the upper positioning plate 4 and the lower positioning plate 5 and a flange 7 is provided therethrough. A feed pipe 8 is provided at the lower end of the flange 7. A crossbeam 9 is installed in the feed pipe 8. A transmission shaft 11 is rotatably provided on the crossbeam 9. A plurality of stirring blades 12 are provided outside the transmission shaft 11.

[0032] In the present embodiment, in actual production operations, the dropped filler is stirred by a plurality of stirring blades 12, and then gradually falls into the distillation tower body 1 along the opening of the feed pipe 8 to complete the distillation treatment. The provided stirring blades 12 can promote the uniform mixing of the feed, and then disperse it in the distillation tower body 1; compared with the quantitative feeding method in the cited document, the distillation tower body 1 of the present application can avoid local accumulation and uneven distribution, thereby improving the mixing degree of the liquid in the tower, making the temperature and composition more uniform, thereby improving the separation efficiency of the distillation. At the same time, the stirring treatment of the provided stirring blades 12 can also avoid the blockage of the filler in the feed pipe 8, reduce the risk of blockage and damage of the distillation tower body 1, and improve the stability and reliability of the distillation operation.

[0033] Furthermore, in actual use, the adjustment component 3 can be used to quantitatively feed the filler, and the adjustment plate 35 with a controllable moving distance can be accurately moved and closed between the upper positioning plate 4 and the lower positioning plate 5, so as to achieve precise closure of the inner tube 21; this can ensure that there is no leakage or excessive feeding during the feeding process, and ensure the accuracy and stability of the feeding of the inner tube 21, which is more accurate and reliable than the quantitative feeding method in the cited documents.

[0034] Specifically, refer to Figure 2-3 The upper end surface of the flange 7 is connected to the inner tube 21, and the adjustment plate 35 slides between the upper positioning plate 4 and the lower positioning plate 5 and can completely seal the inner tube 21 and the flange 7.

[0035] In this embodiment, in actual use, the amount of discharge from the discharge port of the inner tube 21 is adjusted by the stroke of the adjusting plate 35 through the sliding of the adjusting plate 35 between the upper positioning plate 4 and the lower positioning plate 5; when the adjusting plate 35 is closer to the upper positioning plate 4 and the lower positioning plate 5, the opening size of the inner tube 21 will gradually decrease, thereby gradually reducing the amount of discharge of the inner tube 21. Similarly, when the adjusting plate 35 reduces the shielding range of the inner tube 21, the amount of discharge of the inner tube 21 will gradually increase. The user can accurately control the moving stroke of the adjusting plate 35, thereby ensuring the accuracy and stability of the feeding of the inner tube 21 and realizing quantitative feeding.

[0036] Specifically, refer to Figure 2-3 Adjusting bolts 6 are arranged at the four corners of the upper positioning plate 4 and the lower positioning plate 5, and the upper positioning plate 4 and the lower positioning plate 5 are installed by adjusting bolts 6.

[0037] In this embodiment, the adjusting bolt 6 can be used to install the upper positioning plate 4 and the lower positioning plate 5. At the same time, the adjusting bolt 6 can also adjust the distance between the upper positioning plate 4 and the lower positioning plate 5, thereby realizing the adjustment of different distances between the upper positioning plate 4 and the lower positioning plate 5.

[0038] Specifically, refer to Figure 4 A bearing is assembled on the cross beam 9, and the top end of the transmission shaft 11 rotates in the bearing.

[0039] In this embodiment, when the transmission shaft 11 rotates, the bearing member disposed on the cross beam 9 can ensure that the transmission shaft 11 rotates smoothly, reduce the radial load of the transmission shaft 11, and further ensure that the transmission shaft 11 rotates without displacement or significant vibration.

[0040] Specifically, refer to Figure 4 A rotating motor 10 is mounted on the cross beam 9 , and an output end of the rotating motor 10 passes through a bearing member and is connected to a transmission shaft 11 .

[0041] In this embodiment, during use, the user connects a power source to the rotating motor 10 so that the rotating motor 10 can drive the transmission shaft 11 to rotate. At this time, a plurality of stirring blades 12 installed on the outside of the transmission shaft 11 will rotate synchronously with the transmission shaft 11, thereby achieving the stirring process of the filler. After the dropped filler is stirred by the plurality of stirring blades 12, it can gradually fall into the distillation tower body 1 along the opening of the discharge pipe 8 to complete the distillation process.

[0042] Specifically, refer to Figure 2-3 The two opposite sides of the two screw boxes 31 are provided with sliding grooves, and a reciprocating motor 32 is assembled in the screw box 31. The output end of the reciprocating motor 32 is connected to a screw rod 33, and a slider seat 34 is engaged and slidably engaged with the outside of the screw rod 33. The two sides of the adjustment plate 35 are respectively connected to one of the slider seats 34.

[0043] In this embodiment, the reciprocating motor 32 is used to drive the screw rod 33 to rotate. When the screw rod 33 rotates, it is limited by the installation of the adjustment plate 35. At this time, the two slider seats 34 engaged on the outside of the screw rod 33 will move in a straight line along the travel range of the screw rod 33, thereby driving the adjustment plate 35 to move in a reciprocating straight line within the travel range of the screw rod 33, thereby realizing movement within the upper positioning plate 4 and the lower positioning plate 5.

[0044] The distillation tower with quantitative feeding function of the utility model:

[0045] Step 1: When the user feeds the distillation tower, the filler to be fed is poured into the feeding pipe. At this time, the user connects the two reciprocating motors 32 to a power source, so that the output end of the reciprocating motor 32 drives the screw 33 to rotate, and is limited by the installation of the adjustment plate 35. At this time, the two slider seats 34 engaged with the outside of the screw 33 will move linearly along the travel range of the screw 33, thereby driving the adjustment plate 35 to move reciprocatingly linearly within the travel range of the screw 33;

[0046] Step 2: Through the spacing separation setting between the upper positioning plate 4 and the lower positioning plate 5, and the installation setting of the inner tube 21 and the upper positioning plate 4, when the adjusting plate 35 is moving, the user can control the shielding stroke of the adjusting plate 35 on the upper positioning plate 4, so that the size of the discharge port of the inner tube 21 is adjusted by the stroke of the adjusting plate 35. At this time, when the adjusting plate 35 is closer to the upper positioning plate 4 and the lower positioning plate 5, the opening size of the inner tube 21 will gradually decrease, so that the discharge amount of the inner tube 21 can be gradually reduced. Similarly, when the adjusting plate 35 reduces the shielding range of the inner tube 21, the discharge amount of the inner tube 21 will gradually increase. The user can achieve quantitative feeding by controlling the shielding range of the inner tube 21 by the adjusting plate 35, and coordinating the connection setting between the inner tube 21 and the discharge pipe 8;

[0047] Step 3: After the filler falls into the discharge pipe 8 through the inner tube 21, the user connects the power supply to the rotating motor 10 so that the rotating motor 10 can drive the transmission shaft 11 to rotate. At this time, the several stirring blades 12 installed on the outside of the transmission shaft 11 will rotate synchronously with the transmission shaft 11, thereby achieving the stirring process of the filler. After the dropped filler is stirred by the several stirring blades 12, it can gradually fall into the distillation tower body 1 along the opening of the discharge pipe 8 to complete the distillation process.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
