Description

Technical Field

[0001] This utility model relates to the field of distillation apparatus technology, and in particular to a distillation apparatus for the production of anthraquinone. Background Technology

[0002] Anthraquinone is an organic compound and a synthetic natural dye. The basic nucleus of anthraquinone compounds is anthraquinone, which often has substituents such as hydroxyl, hydroxymethyl, methyl, methoxy, and carboxyl groups. It is an important intermediate for higher dyes in organic synthesis, such as indanthrene-based vat dyes, acid dyes, and some reactive dyes. Distillation is a separation process that uses the different volatility of components in a mixture to separate the components. Commonly used equipment includes plate distillation columns and packed distillation columns.

[0003] In the production of anthraquinone, a distillation unit is required. During the operation of the distillation unit, pipes are needed to connect to it. However, most existing distillation units use multiple bolts to connect the pipes, which is cumbersome, wastes a lot of time, reduces work efficiency, and thus has poor practicality. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To solve the above-mentioned technical problems, this utility model provides a distillation apparatus for anthraquinone production that is easy to connect, improves working efficiency, and enhances practicality.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a distillation apparatus for anthraquinone production, comprising a reactor, with a feed pipe and a discharge pipe respectively connected to the top and bottom of the reactor. A first flange and a switching valve are provided on the discharge pipe. The connecting mechanism includes a conveying pipe. A threaded ring is screwed onto the discharge pipe, with two handles fixedly installed on the threaded ring. A movable ring is rotatably installed on the threaded ring, with a limiting groove formed on the movable ring. A limiting block is fixedly installed on the discharge pipe, slidingly connected to the limiting groove. Four L-shaped plates are hinged to the movable ring. A second flange is provided on the conveying pipe, fitting against the first flange. Multiple L-shaped plates are tightly fitted to the bottom of the second flange. The limiting mechanism is installed on the conveying pipe to limit the movement of the four L-shaped plates.

[0008] By adopting the above technical solution, the second flange of the conveying pipe is attached to the first flange on the discharge pipe. Then, multiple L-shaped plates are rotated vertically downwards under the action of gravity. The movement direction of the L-shaped plates is limited by the limiting mechanism. By rotating the threaded ring with the handle, the threaded ring spirals upwards on the discharge pipe, driving the moving ring to move upwards under the limiting action of the limiting block. This drives multiple L-shaped plates to move upwards until all L-shaped plates are in close contact with the ground of the second flange, thereby quickly connecting the discharge pipe and the conveying pipe. This process facilitates the rapid connection of the conveying pipe, improves work efficiency, and enhances practicality.

[0009] Preferably, the limiting mechanism includes a base plate, on which a spring is provided, and a limiting ring is fixedly connected to the top of the spring. The outer walls of multiple L-shaped plates are all in contact with the inner side wall of the limiting ring, and the spring and the limiting ring are all fitted with the conveying pipeline.

[0010] By adopting the above technical solution, when the limiting ring is pressed down and multiple L-shaped plates are vertically downward, the limiting ring is slowly released, the limiting ring rises and resets, and the multiple L-shaped plates fit against the inner wall of the limiting ring, thus preventing the L-shaped plates from shifting when moving, thereby improving practicality.

[0011] Preferably, the first flange is provided with a first sealing groove, and a sealing gasket is provided in the first sealing groove; the top of the second flange is provided with a second sealing groove, and the top of the sealing gasket is inserted into the second sealing groove.

[0012] By adopting the above technical solution, the sealing gasket can improve the sealing performance at the connection between the first flange and the second flange.

[0013] Preferably, two insert rods are fixedly installed at the top of the second flange, and two insertion holes are opened at the bottom of the first flange, with the two insert rods respectively engaging with the two insertion holes.

[0014] By adopting the above technical solution, when the first flange and the second flange are fitted together, the insert rod on the second flange will be inserted into the insertion hole of the first flange to limit the second flange, thereby improving stability.

[0015] Preferably, the movable ring is provided with multiple magnetic stickers.

[0016] By adopting the above technical solution, the L-shaped plate can be magnetically attached to the moving ring for fixation, and then rotated downwards when in use, thereby improving its practicality.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this application provides a distillation apparatus for anthraquinone production, which has the following advantages:

[0019] The second flange of the conveying pipe is attached to the first flange on the discharge pipe. Then, multiple L-shaped plates are rotated vertically downwards under gravity. The movement direction of the L-shaped plates is limited by a limiting mechanism. By holding the handle and rotating the threaded ring, the threaded ring spirals upwards on the discharge pipe, driving the moving ring to move upwards under the limiting action of the limiting block. This drives multiple L-shaped plates to move upwards until all L-shaped plates are in close contact with the ground of the second flange, thus quickly connecting the discharge pipe and the conveying pipe. This process facilitates quick connection of the conveying pipe, improves work efficiency, and enhances practicality. Attached Figure Description

A limiting block 10 is fixedly installed on the discharge pipe 3, and the limiting block 10 is slidably connected to the limiting groove 9. Four L-shaped plates 11 are hinged to the movable ring 8. A second flange 12 is installed on the conveying pipe 5, which is fitted to the first flange 4. The multiple L-shaped plates 11 are all tightly fitted to the bottom end of the second flange 12. The limiting mechanism is installed... On the conveying pipe 5, four L-shaped plates 11 are used to limit their movement. The second flange 12 of the conveying pipe 5 is then attached to the first flange 4 on the discharge pipe 3. The multiple L-shaped plates 11 are then rotated vertically downwards under the action of gravity. The movement direction of the L-shaped plates 11 is limited by the limiting mechanism. By holding the handle 7 and rotating the threaded ring 6, the threaded ring 6 spirals upwards on the discharge pipe 3, driving the moving ring 8 to move upwards under the limiting action of the limiting block 10. This drives the multiple L-shaped plates 11 to move upwards until all the L-shaped plates 11 are in close contact with the ground of the second flange 12, thereby quickly connecting the discharge pipe 3 and the conveying pipe 5. This process facilitates the quick connection of the conveying pipe 5, improves work efficiency, and enhances practicality.

[0032] Please see Figures 1-4 The limiting mechanism includes a base plate 13, on which a spring 14 is provided. A limiting ring 15 is fixedly connected to the top of the spring 14. The outer walls of multiple L-shaped plates 11 are all in contact with the inner wall of the limiting ring 15. The spring 14 and the limiting ring 15 are both fitted with the conveying pipe 5. When the limiting ring 15 is pressed down and the multiple L-shaped plates 11 are vertically downward, the limiting ring 15 is slowly released, and the limiting ring 15 rises and resets. The multiple L-shaped plates 11 are in contact with the inner wall of the limiting ring 15, which prevents the L-shaped plates 11 from shifting when moving, thereby improving practicality.

[0033] Please see Figures 2-4 The first flange 4 is provided with a first sealing groove, and a sealing gasket 16 is provided in the first sealing groove. The top of the second flange 12 is provided with a second sealing groove, and the top of the sealing gasket 16 is inserted into the second sealing groove.

[0036] This utility model discloses a distillation apparatus for anthraquinone production. During operation, the second flange 12 of the conveying pipe 5 is attached to the first flange 4 on the discharge pipe 3. Then, multiple L-shaped plates 11 are rotated vertically downwards under gravity, pressing down on the limiting ring 15. As the multiple L-shaped plates 11 move vertically downwards, the limiting ring 15 is slowly released, causing it to rise and reset. The multiple L-shaped plates 11 are then attached to the inner wall of the limiting ring 15, preventing displacement during movement. The handle 7 is held to rotate the threaded ring 6, which spirals upwards on the discharge pipe 3, driving the moving ring 8 upwards under the limiting action of the limiting block 10. This causes the multiple L-shaped plates 11 to move upwards until they are all tightly attached to the ground of the second flange 12, thus quickly connecting the discharge pipe 3 to the conveying pipe 5. This process facilitates a quick and easy connection of the conveying pipe 5.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
