Description

Technical Field

[0001] The present invention relates to the technical field of triazole production, and specifically to a drying device that can prevent triazole materials from caking and precisely control moisture. Background Art

[0002] As a kind of nitrogen-containing five-membered heterocyclic compound, triazole has excellent biological activity and chemical reactivity due to its unique conjugated system and electronic effects, making it an important intermediate for pharmaceuticals and pesticides. For example, it is an important raw material for the antifungal drug fluconazole, and also an important raw material for pesticides such as triadimefon and tebuconazole, and so on.

[0003] In Chinese Patent Publication No. CN222298351U, a drying and collecting device for benzotriazole production is disclosed, including a bottom plate; a drying chamber is fixedly connected to the upper end of the bottom plate, a steam outlet is fixedly connected to the upper end of the drying chamber, and the inner cavity of the drying chamber is communicated with the inner cavity of the steam outlet. A plurality of mesh plate structures are slidably connected in the inner cavity of the drying chamber, and a driving structure is arranged on one side of the drying chamber, and the driving structure is used to push the mesh plate structures to shake in the inner cavity of the drying chamber. In the present utility model, the output end of the electric push rod drives the second connecting plate to move back and forth, so that the second connecting plate can drive the third connecting plate to move back and forth, and then the third connecting plate can drive a plurality of mesh plate structures to move back and forth in the inner cavity of the drying chamber, so as to drive the benzotriazole placed on the plurality of mesh plate structures to shake back and forth.

[0041] In the present invention, descriptions such as "first" and "second" are only for descriptive purposes, and do not particularly refer to the order or sequence. Nor are they used to limit the present invention. They are merely used to distinguish protection components or operations described with the same technical terms, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. Additionally, the technical solutions and technical features between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0042] Embodiment 1

[0043] Please refer to Figures 1-3, An anti-caking and moisture-precision-control drying device for triazole materials, including a housing 1. Inside the housing 1, a number of drying trays 2 are arranged in parallel. On the drying trays 2, a number of heating elements 9 are provided. The heating elements 9 are evenly distributed and relatively independent of each other. At the bottom of the drying trays 2 and the top inside the housing 1, temperature sensors 10 are provided. The temperature sensors 10 are used to detect the temperature distribution of the lower-side materials.

[0044] Among them, the temperature sensors 10 can be replaced by infrared thermal imaging technology.

[0045] Among them, the heating elements 9 can be microwave generators.

[0046] The working principle and beneficial effects of the above solution:

[0047] In this application, the materials on the lower-side drying trays 2 are monitored by the temperature sensors 10. When it is detected that the temperature in a certain area rises abnormally, which may cause the dissolution and caking of triazole, the power of the heating elements 9 here is reduced to lower the temperature by 2 - 5 °C, ensuring uniform drying temperature of the materials and avoiding caking caused by local overheating after the dissolution of triazole.

[0048] Embodiment 2

[0049] Please refer to Figure 1 , On the basis of Embodiment 1, a feed bin 4 is provided at the top of the housing 1, and a feed pipe 5 is arranged inside the housing 1. The feed pipe 5 is communicated with the feed bin 4;

[0050] The feed pipe 5 is provided with downwardly inclined pipe openings at the upper-side positions of any group of drying trays 2.

[0051] A base 3 is provided at the bottom of the housing 1.

[0052] The working principle and beneficial effects of the above solution:

[0053] The materials in the feed bin 4 enter the drying trays 2 through the inclined pipe openings of the feed pipe 5 for drying.

[0054] Embodiment 3

[0055] Please refer to Figures 4-5 , On the basis of Embodiment 1, ventilation openings 8 are provided at the top and side walls of the housing 1, and a wind direction adjustment component is provided at the ventilation openings 8.

[0056] Preferably, the wind direction adjustment component can optimize the air duct design by using CFD (Computational Fluid Dynamics) simulation technology to ensure uniform distribution of hot air in the dryer and avoid the occurrence of ventilation dead spots.

[0057] Preferably, a humidity sensor can be arranged inside the housing 1, and the ventilation opening 8 and the wind direction adjusting component work according to the detection result of the humidity sensor.

[0058] The wind direction adjusting component includes a fixed support block 11 fixedly connected to the inner wall of the housing 1. One end of a telescopic rod 12 is rotatably connected to the fixed support block 11. The other end of the telescopic rod 12 is rotatably connected to a driving rod 13. The end of the driving rod 13 away from the telescopic rod 12 is connected to one end of an adjusting rod 19. A second limit slide rod 18 is arranged at the end of the adjusting rod 19 close to the driving rod 13. The second limit slide rod 18 is slidably connected in a second slide rail 21 arranged on a track disk 14. The track disk 14 is fixedly connected to the inner wall of the housing 1;

[0059] The driving rod 13 is rotatably connected to the track disk 14;

[0060] A first limit slide rod 15 is arranged at the middle position of the adjusting rod 19. The first limit slide rod 15 is slidably connected in a first slide rail 17 arranged on the track disk 14;

[0061] One end of a tension spring 16 is connected to the end of the adjusting rod 19 away from the second limit slide rod 18. The other end of the tension spring 16 is connected to the track disk 14;

[0062] A ventilation opening mounting head 20 is arranged at the end of the adjusting rod 19 away from the second limit slide rod 18. The ventilation opening mounting head 20 is used for mounting the ventilation opening 8.

[0063] The second slide rail 21 is arc-shaped, and the tangent line at the middle position of the second slide rail 21 is perpendicular to the first slide rail 17;

[0064] The connection point of the tension spring 16 on the track disk 14 is the symmetric point of the end of the first slide rail 17 with respect to the connection line of the two ends of the second slide rail 21.

[0065] Working principle of the above solution: When the humidity sensor detects that the humidity in a certain area is greater than that in the surrounding areas, the wind direction needs to be adjusted at this time. By adjusting the length of the telescopic rod 12, the driving rod 13 connected to the telescopic rod 12 rotates around its connection point on the track disk 14. When the telescopic rod 12 shortens, the driving rod 13 rotates clockwise. When the telescopic rod 12 elongates, the driving rod 13 rotates counterclockwise. The rotation of the driving rod 13 causes the end away from the telescopic rod 12 to drive the adjusting rod 19 to swing under the restriction of the first slide rail 17 and the second slide rail 21, and under the pulling force of the tension spring 16, three postures are formed at the limit positions of the first slide rail 17 and the second slide rail 21, corresponding to three orientations of the ventilation opening 8. When the driving rod 13 rotates clockwise to the limit position, the second limit slide rod 18 slides to the lower side direction of the second slide rail 21, and the ventilation opening mounting head 20 is facing upward, and the area in this direction can be dehumidified. When the driving rod 13 rotates counterclockwise to the limit position, the second limit slide rod 18 slides to the upper side direction of the second slide rail 21, and the ventilation opening mounting head 20 is facing downward, and the area in this direction can be dehumidified. When the driving rod 13 rotates to the midpoint position, the first limit slide rod 15 slides to the end of the first slide rail 17, and the orientation of the ventilation opening mounting head 20 is the same as the direction of the first slide rail 17, and the area in this direction can be dehumidified. As Figure 5 shown;

[0066] Beneficial effects of the above solution: A plurality of ventilation openings 8 are provided on the top and side of the housing 1. Through the wind direction adjustment assembly installed on the ventilation openings 8, the ventilation mode is adjusted in real time according to the moisture distribution of the material during the drying process. For example, when it is detected that the moisture content of a certain part of the material is relatively high, the ventilation opening 8 is adjusted to face this area, increasing the air volume of the corresponding ventilation opening in this area, increasing the air volume by 30%-50%, and accelerating the evaporation of moisture.

[0067] The drying of the material is made more uniform through three-speed wind direction adjustment, avoiding the situation of long overall drying time caused by poor local drying effect, and effectively improving the drying efficiency.

[0068] Through the reasonable cooperation of ventilation and the heating element 9 (microwave generator), the microwave power is dynamically adjusted according to the drying process and moisture content of the material. In the initial stage of drying, the moisture content of the material is high, and a relatively high microwave power (such as 500-800W) is used to promote the rapid evaporation of moisture. As the drying progresses, the microwave power is gradually reduced (such as 100-300W) to prevent the dissolution of triazole due to excessive microwave heating. At the same time, the humidity inside the dryer is monitored in real time through the humidity sensor. When the humidity reaches a certain threshold, the ventilation opening 8 is opened to discharge the moisture in time, improving the drying efficiency.

[0069] Example 4

[0070] Please refer to Figure 1 、Figures 6-9 , on the basis of Embodiment 1, a crushing rotating shaft 7 is arranged inside the housing 1, the crushing rotating shaft 7 penetrates through the drying tray 2, and a crushing assembly 6 is arranged on the crushing rotating shaft 7, and the crushing assembly 6 is located on the upper surface of the drying tray 2.

[0071] The crushing assembly 6 includes a plurality of driving gears 33 fixed on the crushing rotating shaft 7, an internal gear disk 35 is rotatably connected to the crushing rotating shaft 7, and the internal gear disk 35 can rotate on the same horizontal plane of the crushing rotating shaft 7;

[0072] The driving gear 33 meshes with a plurality of groups of driven gears 34, the driven gears 34 are fixedly connected to the driven rotating shafts 36, the driven rotating shafts 36 are rotatably connected to the internal gear disk 35, and the driven gears 34 mesh with the teeth on the circumferential side of the internal gear disk 35.

[0073] A telescopic groove 38 is arranged on the driven rotating shaft 36, an adjusting slider 40 is nested in the telescopic groove 38, the telescopic groove 38 and the adjusting slider 40 can slide along the axial direction, and torque can be transmitted between the telescopic groove 38 and the adjusting slider 40;

[0074] An adjusting spring 39 is arranged between the telescopic groove 38 and the adjusting slider 40;

[0075] A transmission rod 41 is fixedly connected to the adjusting slider 40, and a transmission head 42 is fixedly connected to the transmission rod 41;

[0076] A universal joint sleeve 43 is fixedly connected to the transmission head 42, a limit receiving groove 45 is arranged inside the universal joint sleeve 43, a universal sliding groove 47 is arranged on the upper part of the limit receiving groove 45, a universal ball 44 is nested in the limit receiving groove 45, the universal ball 44 can rotate in the limit receiving groove 45, a universal transmission rod 46 is arranged on the universal ball 44, the universal transmission rod 46 is slidably connected in the universal sliding groove 47, and the universal ball 44 is connected to the crushing piece 52 through a fixed head 48.

[0077] A fixing hole 49 is arranged at the center of the crushing piece 52, and the fixing hole 49 is clamped to the fixed head 48;

[0078] A first crushing and stirring piece 50 and a second crushing and stirring piece 51 are arranged on one side surface of the crushing piece 52, the first crushing and stirring piece 50 is located at the outer edge of the crushing piece 52, and the second crushing and stirring piece 51 is located inside the circumference of the first crushing and stirring piece 50;

[0079] The ends of the first crushing and stirring piece 50 and the second crushing and stirring piece 51 are both attached to the drying tray 2, and both the first crushing and stirring piece 50 and the second crushing and stirring piece 51 have elasticity

[0080] Working principle of the above solution: For the stirring and crushing operation, an external driving force (such as a motor connected to the crushing rotating shaft 7) drives the crushing rotating shaft 7 to rotate, causing the driving gear 33 to rotate. The internal gear disk 35 is rotatably connected to the crushing rotating shaft 7, and the two are not fixed. When the driving gear 33 rotates, it drives the driven gear 34 to rotate, and then drives the internal gear disk 35 to rotate. The crushing pieces 52 connected to the driven gear 34 not only rotate on their own but also rotate around the crushing rotating shaft 7, stirring and crushing the materials on the drying disk 2 evenly.

[0081] For the decontamination operation, when materials adhere to the drying disk 2, the slider 40 is adjusted to be inserted into the telescopic groove 38, and an adjusting spring 39 is arranged between the two, so that the distance between the crushing pieces 52 and the driven rotating shaft 36 can be compressed, that is, the crushing pieces 52 can slide over the surface of the adhered materials, and the adhered materials are removed by the friction between the crushing pieces 52 and the material surface multiple times.

[0082] Beneficial effects of the above solution:

[0083] A crushing assembly 6 is arranged inside the housing 1, which can generate a gentle dispersing force on the materials during the stirring process. The stirring device is automatically started according to a preset time interval or by real-time monitoring of the material caking situation (such as using an ultrasonic sensor to detect the caking situation inside the materials).

[0084] When it is detected that the materials have a tendency to cake, the stirring paddle rotates slowly at a low speed (such as 50 - 100 revolutions per minute) to disperse the materials; if small lumps have formed, the stirring speed is increased (such as 150 - 200 revolutions per minute) to break the lumps and restore the materials to a uniform state, and continue drying to ensure that the materials remain loose throughout the drying process, effectively solving the problems of uneven moisture and product appearance caused by caking.

[0085] During the stirring and crushing, an external driving force (such as a motor connected to the crushing rotating shaft 7) drives the crushing rotating shaft 7 to rotate, causing the driving gear 33 to rotate. The internal gear disk 35 is rotatably connected to the crushing rotating shaft 7, and the two are not fixed. When the driving gear 33 rotates, it drives the driven gear 34 to rotate, and then drives the internal gear disk 35 to rotate. The crushing pieces 52 connected to the driven gear 34 not only rotate on their own but also rotate around the crushing rotating shaft 7, stirring and crushing the materials on the drying disk 2 evenly.

[0086] When materials adhere to the drying disk 2, the materials will be higher than the surface of the drying disk 2, and when the crushing pieces 52 perform the shoveling operation along the surface of the drying disk 2, the resistance received by the drive will increase significantly, which may cause the drive (such as a motor) to self-protect and stop rotating. To avoid this situation, the adhered materials are removed by the friction between the crushing pieces 52 and the material surface multiple times, and the stop or damage of the drive is also avoided.

[0087] The arrangements of the universal joint sleeve 43, the universal ball 44, the limit accommodating groove 45, the universal transmission rod 46, and the universal sliding groove 47 enable the crushing piece 52 to have freedom in multiple directions, so that the crushing piece 52 can always fit the drying tray 2 or the surface of the material adhered to the drying tray 2, ensuring the efficiency of stirring, crushing, and cleaning.

[0088] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
