Description

Technical Field

[0001] This utility model relates to the technical field of novel D-ester production equipment, specifically a drying device for novel D-ester production. Background Technology

[0002] In the industrial production of D-esters (such as high-value-added pharmaceutical intermediates like D-p-methylphenylserine ethyl ester), the drying process is a core step in controlling product quality and production efficiency. Existing drying technologies generally face the common industry problem of material sticking to the walls, especially when processing heat-sensitive, high-viscosity, or water-of-crystal D-esters. This problem leads to a surge in production costs and exacerbates quality risks.

[0003] In current industrial practice, three main technical approaches are used to address the problem of material sticking to the walls during drying. One approach involves forcibly turning the material using paddle agitators and screw propellers, but high-speed shearing easily damages the D-ester crystal structure (reducing specific rotation by 10%-15%), and the dynamic sealing structure has a high annual leakage rate under high temperature and pressure. Another approach uses Teflon coatings and silicone rubber linings to reduce wall adhesion, but the coatings lack wear resistance (70% reduction in anti-sticking performance after 6 months), and the temperature threshold (≤120℃) cannot match the process requirements. A third approach utilizes high-speed airflow tangential impact to peel off the sticking material, but this is energy-intensive (requiring an additional 30kW fan), and the dust concentration is close to the lower explosive limit (LEL 40%-50%), posing a significant safety hazard.

[0004] Therefore, a drying device for the novel production of D-esters is proposed to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see Figure 1-4This embodiment of a drying apparatus for the production of novel D-esters includes a mounting frame 1. A drying element 12 for drying is mounted on the top of the mounting frame 1. The drying element 12 includes a feed end 121 for feeding material, a drying tank 123 for auxiliary drying, and a discharge end 122 for discharging material. The feed end 121 includes a housing mounted on the mounting frame 1. A feed cone 1211 for feeding material is mounted on the top of the housing. An air inlet 1212 for air intake is also provided on one side of the housing. An air inlet filter is provided externally to the air inlet 1212, and a fan and electric heating wire are provided internally. The discharge end 1212... 2 has a hollow structure and is equipped with multiple paddles for turning D-ester inside. Its two ends are rotatably connected to the feed end 121 and the discharge end 122. Its outer periphery is also fixedly connected to a chain 1231 for easy linkage. The mounting frame 1 is also equipped with a transmission component 11 for transmission. The transmission component 11 includes a transmission motor and a reducer. The reducer shaft is driven to a transmission wheel. The transmission wheel is driven to a linkage component 2 through a transmission belt. The linkage component 2 is driven to the chain 1231. The linkage component 2 is also driven to a drive component 3 to prevent D-ester residue in the drying tank 123.

[0025] In practical use, the operator can feed the D-ester drug to be dried into the drying tank 123 through the feed cone 1211. At the same time, the operator can heat the outside air by activating the electric heating wire and the fan and blow it into the drying tank 123 to achieve the effect of drying the D-ester drug. During this process, the operator can also activate the transmission component 11 to drive the linkage component 2 to make the drying tank 123 rotate, so that the D-ester drug inside can be dried evenly. In addition, during the rotation of the linkage component 2, the drive component 3 can effectively drive the driving component 3 to impact the drying tank 123, so that the outer shell of the drying tank 123 can vibrate. During the vibration of the outer shell of the drying tank 123, the residual D-ester drug adhering to the inner wall of the drying tank 123 can be dislodged, thus avoiding the sticking.

[0026] The technical effects of the above embodiments are as follows: by setting the driving component 3, it can effectively drive the drying tank 123 to vibrate during the drying of D-ester drugs under the action of the linkage component 2, thereby avoiding the occurrence of drug residue or accumulation on its inner wall; compared with the cleaning method in the prior art, it reduces the waste of raw materials generated during the drying of D-ester drugs, while increasing its drying efficiency and reducing drying costs.

[0027] As a preferred technical solution in this embodiment: the linkage component 2 includes two bearing seats 21 mounted on the mounting frame 1. A drive shaft is rotatably connected to the two bearing seats 21. The drive shaft is provided with a sprocket 22 for transmission and a driven pulley that cooperates with the transmission belt. The sprocket 22 is driven by the chain 1231. One end of the drive shaft extends to the outside of the bearing seat 21 and is fixedly connected to a transmission cam 24. The transmission cam 24 is driven by the drive component 3. In actual use, when the operator controls the transmission motor and reducer on the transmission component 11 to drive the drive wheel, the drive wheel can drive the driven pulley through the transmission belt, causing the drive shaft sprocket 22 and the transmission cam 24 to rotate. During the rotation of the sprocket 22, the chain 1231 can be effectively driven to rotate the drying tank 123, thereby enabling the D-ester drug inside to be heated evenly. During the rotation of the transmission cam 24, the drive component 3 can be effectively driven, allowing the drive component 3 to impact the drying tank 123, thus ensuring its operation during use.

[0028] As a preferred technical solution in this embodiment: the drive assembly 3 includes a mounting ring 31 mounted on one side of the bearing seat 21. A guide tube 32 is provided on the mounting ring 31, and a connecting rod 33 for driving is slidably connected inside the guide tube 32. One end of the connecting rod 33 is located outside the mounting ring 31 and is fixedly connected to a striking platform 34; the other end is located inside the mounting ring 31 and is fixedly connected to a transmission platform 35. A reset spring 36 for resetting is provided on the transmission platform 35, and the other end of the reset spring 36 is fixedly connected to the inner wall of the mounting ring 31. The outer sides of both the striking platform 34 and the transmission platform 35 are arc-shaped, and the striking platform 34 is made of rubber, while the transmission platform 35 is made of metal. In actual use, when the operator controls the transmission cam 24 to rotate, the protruding part of the transmission cam 24 will contact the transmission table 35, thereby lifting the transmission table 35 and causing it to move. During the displacement of the transmission table 35, it can drive the connecting rod 33 and the striking table 34 to move, while squeezing the return spring 36 to store energy. During the displacement of the striking table 34, it can achieve the impact effect on the drying tank 123, thereby causing the drying tank 123 to vibrate and remove the material adhering to the inner wall of the drying tank 123. When the protruding part of the transmission cam 24 leaves the transmission table 35, the transmission table 35 will be reset under the action of the return spring 36 to provide the stroke for the next impact on the drying tank 123.

[0029] The technical effects of the above embodiments are as follows: by setting the transmission cam 24 and the transmission platform 35, the device can achieve the transmission effect of the connecting rod 33 and the striking platform 34 with only one drive source during use, which ensures the convenience of the device during use and reduces its operating cost. By setting the return spring 36, the device can effectively control the transmission platform 35 to return to its original position, which increases its stability during use.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
