[0002] Norfloxacin chelate refers to the complex compound formed by the coordination bond between norfloxacin molecules and metal ions or other ligands. In this compound, norfloxacin acts as a ligand, forming a coordination bond with metal ions (such as copper, zinc, iron, etc.) or other ligands through certain functional groups in its molecules (such as carboxyl, hydroxyl, etc.), thus constituting a stable chelate structure. Norfloxacin itself is a broad-spectrum antibacterial drug, mainly used for the treatment of various infections caused by sensitive bacteria. Norfloxacin chelate may have some special properties, such as improving the stability of the drug, improving its solubility, enhancing its antibacterial activity against specific pathogens, etc. These properties make norfloxacin chelate have potential application value in certain specific therapeutic areas or drug research and development.

[0003] The existing norfloxacin chelate liquid is heated in a reaction kettle, steam enters the distillation column, and passes through the tower plates layer by layer from bottom to top, then the steam at the top of the distillation column is condensed by the condenser into liquid, then the liquid is transported to the top of the distillation column, then the liquid starts to fall on the tower plates from top to bottom and falls, then the discharge valve at the bottom of the distillation column discharges the distilled liquid.

[0004] Although the above device can distill norfloxacin chelate liquid, when the norfloxacin chelate liquid becomes steam, the impurities carried in the steam accumulate with the sediment, the flow area of the tower plate gradually decreases, and eventually leads to blockage, thereby affecting the falling of the distilled liquid.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figures 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figures 1-4 As shown: This embodiment provides a continuous distillation tower apparatus for producing norfloxacin chelates, including a distillation tower 100. The top of the distillation tower 100 has a steam outlet 102, and the sides of the distillation tower 100 have steam inlets 103 and liquid inlets 101. First, the norfloxacin chelate liquid is placed into a reaction vessel or other heating container. Then, the generated steam enters the steam inlet 103 and floats upwards into the steam outlet 102. The steam outlet 102 is then connected to an existing condenser, causing the steam to be condensed into liquid and then transported back to the liquid inlet 101. The liquid then flows downwards from the top of the distillation tower 100. Multiple trays 111 are arranged alternately inside the distillation tower 100. The trays 111 facilitate the separation of steam and liquid during the distillation process. Overflow weirs 110 are provided on the sides of each of the multiple trays 111. Each tray 111 is equipped with an overflow weir 110 on its side. The overflow weir 110 is used to ensure that the liquid is evenly distributed on the tray 111 and to prevent excessive liquid overflow. A chute 109 is provided on one side of the overflow weir 110 near the end of the distillation column 100. A cleaning component 200 is provided in the chute 109. The cleaning component 200 also includes a slide plate 201 disposed between the chute 109. The slide plate 201 can slide in the chute 109. A cleaning brush 204 is provided on the upper surface of the slide plate 201. The cleaning brush 204 is set to contact the bottom of the tray 111. When the slide plate 201 moves in the chute 109, the cleaning brush 204 can effectively remove the impurities accumulated at the bottom of the tray 111, thereby preventing the holes on the tray 111 from becoming blocked and causing excessive liquid accumulation and overflow on the tray 111. At the same time, it prevents the liquid from dripping from the holes of the tray 111.

[0025] First, the norfloxacin chelate liquid is placed in a reaction vessel or other heating container and heated, and then connected to the steam inlet 103 to generate steam that enters the steam inlet 103. The steam then floats upward to the top of the distillation column 100 and is finally discharged through the steam outlet 102, which is connected to the existing condenser. The condenser condenses the vapor into liquid, which is then returned to the liquid inlet 101 and flows downward from the top of the distillation column 100. Multiple trays 111 are staggered inside the distillation column 100. These trays 111 facilitate the separation of vapor and liquid, promoting the distillation process. Each tray 111 has an overflow weir 110 on its side, ensuring uniform liquid distribution and preventing excessive overflow. As the slide plate 201 moves within the chute 109, the cleaning brush 204 effectively removes impurities accumulated at the bottom of the tray 111, preventing blockage of the holes and avoiding excessive liquid accumulation and overflow. Simultaneously, it ensures that the liquid drips smoothly from the holes of the tray 111, maintaining the normal operation of the distillation process.

[0026] Screw 203 Figure 2 As shown,

[0027] The cleaning assembly 200 also includes lead screws 203 disposed between the slides 109. There is one lead screw 203 between each slide 109. The lead screw 203 is threaded to the center of the slide plate 201. Each lead screw 203 is threaded to the center of each slide plate 201. Thus, each lead screw 203 rotates, thereby driving each slide plate 201 to move, and thus can move at the bottom of the tower plate 111.

[0028] Multiple springs 202 Figure 4 Enlarged view of point B in the image Figure 5 As shown,

[0029] The cleaning assembly 200 also includes a connecting strip 205 disposed at the bottom of the cleaning brush plate 204. The connecting strip 205 is fixed to the cleaning brush plate 204 by welding, thereby playing a connecting role for the cleaning brush plate 204. The connecting strip 205 is located inside the skateboard 201 and can be installed inside the skateboard 201.

[0030] The cleaning assembly 200 also includes a plurality of springs 202 disposed in the slide plate 201. The two ends of the plurality of springs 202 are respectively fixedly disposed at the bottom of the slide plate 201 and the bottom of the connecting strip 205. The springs 202 can provide elastic support for the slide plate 201, thereby facilitating the cleaning brush plate 204 to contact the top of the tower plate 111 for cleaning.

[0031] Synchronous belt pulley 108 Figure 1 As shown,

[0032] Two synchronous pulleys 108 and multiple double-groove synchronous belts 106 are provided on one side of the distillation column 100. The two synchronous pulleys 108 and multiple double-groove synchronous pulleys 106 are fixed to one end of multiple lead screws 203. Multiple double-groove synchronous pulleys 106 are arranged between the two synchronous pulleys 108. The double-groove synchronous pulleys 106 are connected in sequence by synchronous belts 107.

[0033] A support base 104 is provided on the side of the distillation column 100. The support base 104 is fixed to the distillation column 100 by welding. A motor 105 is provided on the side of the support base 104. The output shaft of the motor 105 is fixed on one side of the synchronous pulley 108. The output shaft of the motor 105 can drive the synchronous pulley 108 to rotate.

[0034] When the motor 105 drives the synchronous pulley 108 to rotate, the synchronous belt 107 drives the connected double-groove synchronous pulley 106 to rotate. Since the synchronous belt 107 is continuous and passes through the grooves of each double-groove synchronous pulley 106 in sequence, when one double-groove synchronous pulley 106 rotates, it will drive the next double-groove synchronous pulley 106 to rotate in sequence until all the double-groove synchronous pulleys 106 in the entire transmission path start to rotate.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
