Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a rapid drying device for nucleoside intermediates. Background Technology

[0002] Nucleoside intermediates are key raw materials for the synthesis of antiviral drugs, anticancer agents, and nucleic acid drugs. Their chemical purity and physical state directly affect the bioactivity and efficacy stability of the final products. In the pharmaceutical industry, nucleoside intermediates need to be dried to remove solvent residues and meet the particle size requirements of subsequent reactions. The quality of drying directly affects drug safety and production efficiency.

[0003] Currently, industrial drying generally uses continuous hot air equipment. However, in the early stage of drying, the material surface loses water rapidly and easily forms a hard shell, which causes the internal moisture to be trapped, leading to severe agglomeration. Traditional equipment is difficult to effectively break up these clumps, resulting in uneven drying. In addition, under static spreading conditions, the contact area between the material and the hot air is insufficient, resulting in low drying efficiency, prolonged drying time, and increased energy consumption.

[0004] To address the above issues, we have developed a rapid drying device for nucleoside intermediates. Utility Model Content

[0005] This utility model discloses a rapid drying device for nucleoside intermediates, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid drying device for nucleoside intermediates includes a drying channel:

[0008] The drying channel is equipped with:

[0009] Conveyor belts are used to transport nucleoside intermediates.

[0010] The dust suppression mechanism, located above the conveyor belt, includes:

[0011] A rotating rod, rotating disks fixedly connected to both ends of the rotating rod, fixed rings symmetrically fixed to the outside of the rotating rod, and lifting plates equidistantly connected between the two fixed rings;

[0012] The two ends of the rotating rod penetrate the side wall of the drying channel and are fixed to the rotating disk;

[0013] A dispersion mechanism, symmetrically arranged on the outside of the dust-generating mechanism, includes:

[0014] Rotary connection to the swing shaft in the drying channel, gears fixed at both ends of the swing shaft, and swing plate fixed in the middle section of the swing shaft;

[0015] The drive structure, used to synchronously drive the dust-generating mechanism and the agitation mechanism, includes:

[0016] Connecting rod fixed to the rotating disk;

[0017] Connecting rods symmetrically hinged at both ends of the connecting rod;

[0018] A drive gear plate is hinged to the other end of the connecting rod, and the drive gear plate has a sliding groove.

[0019] A limiting rod fixed to the outside of the drying channel passes through the slide groove and slides in cooperation with the slide groove;

[0020] The drive toothed plate meshes with a gear for transmission.

[0021] In a preferred embodiment, the driving structure further includes:

[0022] A worm gear fixed to the rotating rod;

[0023] Rotate the worm gear connected to the side wall of the drying channel, which meshes with the worm wheel;

[0024] The drive source is fixed outside the drying channel, and its output end is connected to a worm gear.

[0025] In a preferred embodiment, raised rollers are equidistantly arranged inside the drying channel below the conveyor belt. The raised rollers have an elliptical structure. Connecting wheels are fixed on the roller shaft of the raised rollers and the drive rollers of the conveyor belt. Adjacent connecting wheels are connected by a transmission belt.

[0026] The rapid drying device for nucleoside intermediates provided by this utility model has the following advantages:

[0027] This invention utilizes the periodic rotation of a lifting plate to continuously toss the material into the air, increasing the contact area between the nucleoside intermediates and the hot air, thereby improving drying efficiency. Simultaneously, the lateral oscillation of a swing plate disperses the tossed material, effectively eliminating clumping. Furthermore, the elliptical raised rollers drive the conveyor belt to generate regular bumps, forcing the material to vibrate. Combined with dust suppression and dispersing actions, this significantly reduces the agglomeration of nucleoside intermediates during the drying process, ultimately achieving the goals of improving drying efficiency and reducing energy consumption.

The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] This utility model discloses a rapid drying device for nucleoside intermediates.

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rapid drying device for nucleoside intermediates includes a drying channel 1:

[0037] The drying channel 1 is equipped with:

[0038] Conveyor belt 2 is used to transport nucleoside intermediates;

[0039] The dust suppression mechanism, located above conveyor belt 2, includes:

[0040] Rotating rod 3, rotating disk 4 fixedly connected to both ends of rotating rod 3, fixing ring 16 symmetrically fixed to the outside of rotating rod 3, and lifting plate 17 equidistantly connected between the two fixing rings 16;

[0041] The two ends of the rotating rod 3 pass through the side wall of the drying channel 1 and are fixed to the rotating disk 4;

[0042] A dispersion mechanism, symmetrically arranged on the outside of the dust-generating mechanism, includes:

[0043] The swing shaft 10 is rotatably connected to the drying channel 1, the gears 11 are fixed at both ends of the swing shaft 10, and the swing plate 15 is fixed in the middle section of the swing shaft 10.

[0044] The drive structure, used to synchronously drive the dust-generating mechanism and the agitation mechanism, includes:

[0045] Connecting rod 5 fixed on rotating disk 4;

[0046] Connecting rods 6 are symmetrically hinged at both ends of connecting rod 5;

[0047] The drive gear plate 7 is hinged to the other end of the connecting rod 6, and the drive gear plate 7 has a sliding groove 8.

[0048] A limiting rod 9 fixed to the outside of the drying channel 1 passes through the slide groove 8 and slides in cooperation with the slide groove 8;

[0049] Among them, the drive gear plate 7 meshes with the gear 11 for transmission;

[0050] In this embodiment: After the drive source 14 is started, the worm gear 13 drives the worm wheel 12 to rotate, which in turn drives the rotating rod 3 and the lifting plate 17 on the fixed ring 16 to rotate, periodically lifting the nucleoside intermediates on the conveyor belt 2, increasing the contact area between the material and the hot air. At the same time, the rotating rod 3 drives the rotating disk 4 to rotate, forcing the connecting rod 5 to pull the connecting rod 6 to move. The connecting rod 6 pushes the drive tooth plate 7 to slide back and forth along the limiting rod 9 in the slide groove 8. The drive tooth plate 7 meshes with the gear 11, converting the linear motion into the reciprocating rotation of the gear 11. The gear 11 drives the swing shaft 10 and the swing plate 15 to swing left and right, breaking up the material in front of and behind the dust-raising mechanism, preventing agglomeration, and improving the drying efficiency.

[0051] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, the driving structure further includes:

[0052] The worm gear 12 is fixed on the rotating rod 3;

[0053] Rotary connection of worm gear 13 to the side wall of drying channel 1, which meshes with worm wheel 12;

[0054] A drive source 14 is fixed outside the drying channel 1, and its output end is connected to a worm gear 13;

[0055] In this embodiment, the meshing design of the worm gear 12 and the worm 13 has a self-locking characteristic, which can prevent the rotating rod 3 from reversing due to material resistance. The drive source 14 transmits power through the worm 13 to ensure the stable operation of the lifting plate 17.

[0056] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment, raised rollers 18 are equidistantly arranged inside the drying channel 1 below the conveyor belt 2. The raised rollers 18 have an elliptical structure. Connecting wheels 19 are fixed on the roller shaft of the raised rollers 18 and the drive rollers of the conveyor belt 2. Adjacent connecting wheels 19 are connected by a transmission belt 20.

[0057] In this embodiment, the drive roller of the conveyor belt 2 drives the raised roller 18 to rotate synchronously through the connecting wheel 19 and the transmission belt 20. The elliptical structure of the raised roller 18 causes periodic undulations on the surface of the conveyor belt 2. The material is continuously bumped and turned during the conveying process. With the action of the dust-raising mechanism and the stirring mechanism, the internal wet clumps are further broken up to avoid uneven drying in some areas.

[0058] Working principle: After the drive source 14 is started, the worm gear 13 drives the worm wheel 12 to rotate, which in turn drives the rotating rod 3 and the lifting plate 17 on the fixed ring 16 to rotate, periodically lifting the nucleoside intermediates on the conveyor belt 2, so that the material is fully exposed to the hot airflow in the drying channel 1 to increase the drying contact area. At the same time, the rotating rod 3 drives the rotating disk 4 to rotate, which forces the connecting rod 5 to pull the connecting rods 6 on both sides to move, pushing the drive toothed plate 7 to make linear reciprocating motion along the limiting rod 9 in the slide groove 8. The drive toothed plate 7 meshes with the gear 11, converting the linear motion into the reciprocating motion of the gear 11. The rotating mechanism drives the swing shaft 10 and the swing plate 15 fixed on it to swing left and right, mechanically breaking up the material in front of and behind the dust-raising mechanism, effectively preventing clumping. At the same time, the drive roller of the conveyor belt 2 drives the raised roller 18 to rotate synchronously through the connecting wheel 19 and the transmission belt 20. The elliptical structure of the raised roller 18 causes regular undulations on the surface of the conveyor belt 2. The material continuously bumps and tumbles during the conveying process, and the dust-raising and breaking actions work together to eliminate the clumping of nucleoside intermediates, improve drying efficiency, and achieve rapid and uniform drying of nucleoside intermediates.

[0059] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
