Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pharmaceutical dehydration, and in particular to a centrifugal dehydration device for pharmaceutical production. Background Art
[0002] During pharmaceutical production, drugs often require dehydration. Current drug dehydration processes typically utilize vacuum extraction. After dehydration, the drugs are removed from the dehydration equipment and individually dried by heat. During vacuum extraction, one end of the drug pile is connected to the vacuum pump, while the other end is exposed to the atmosphere. This method often compromises the dehydration efficiency due to insufficient compactness of the drug pile, resulting in a low drug dehydration rate, prolonged subsequent heat drying, and increased production costs. Utility Model Content
[0003] In order to solve the problem of low dehydration rate when dehydrating medicines by vacuuming, the present application provides a centrifugal dehydration device for medicine production, which specifically adopts the following technical solution.
[0004] A centrifugal dehydration device for medicine production comprises a tank body, a sealing cover, a centrifugal barrel and a centrifuge.
[0005] The upper end of the tank body is open, and the cover covers the upper opening of the tank body. The cover is provided with a feed port.
[0006] The centrifugal bucket is arranged in the tank body. The side wall of the centrifugal bucket is densely covered with a plurality of penetrating filter holes. The bottom surface of the centrifugal bucket is a cone with a center convex upward.
[0007] The centrifuge is located at the outer bottom of the centrifuge bucket, and the rotating shaft of the centrifuge is upwardly connected to the centrifuge bucket. The tank body is provided with a drainage mechanism for receiving the water discharged from the filter hole and discharging it outside the tank body.
[0008] By adopting the above technical solution, the medicine is dehydrated by centrifugation, and the water is thrown out of the filter holes of the centrifugal barrel from the side. This method can continuously and stably dehydrate, and the water at the bottom of the centrifugal barrel can flow along the conical bottom to the side wall, reducing water accumulation at the bottom.
[0009] A preferred structure of the centrifugal dehydration device for pharmaceutical production is that the drainage mechanism includes an annular drainage groove with a V-shaped cross section located at the inner bottom of the tank body. The drainage groove is seamlessly connected to the inner side wall of the tank body and is located below the side wall of the centrifugal bucket.
[0010] By adopting the above technical solution, the V-shaped annular drainage groove can receive the water thrown out by the centrifugal bucket and discharge it.
[0011] A preferred structure of the centrifugal dehydration device for pharmaceutical production is that the drainage mechanism further includes a drainage pipe, and the drainage pipe is connected to the bottom of the drainage trough.
[0012] By adopting the above technical solution, the water collected in the drainage trough can be discharged out of the tank body through the drainage pipe.
[0013] A preferred structure of the centrifugal dehydration device for pharmaceutical production is that the cover is further provided with an air inlet. The centrifugal dehydration device also includes a hot air system. The hot air system includes a hot air blower, a first air duct, and a second air duct. The first air duct and the second air duct are respectively connected to the hot air blower. The first air duct is connected to the air inlet. The second air duct is connected to the interior of the tank body. The connection between the second air duct and the tank body is located above the drainage mechanism.
[0014] By adopting the above technical solution, the hot air generated by the hot air blower passes through the side walls of the centrifugal barrel of the first air duct and the second air duct and the upper opening of the centrifugal barrel, and dries the medicines in the centrifugal barrel from the side and the front respectively, with high drying efficiency.
[0015] A preferred structure of the centrifugal dehydration device for pharmaceutical production is that a solenoid valve is provided on the second air duct.
[0016] By adopting the above technical solution, during dehydration, the solenoid valve is controlled to be closed to prevent water from entering the second air duct and entering the hot air blower. During drying, the solenoid valve is opened, and hot air enters the tank through the second air duct to dry the medicine in the centrifugal barrel.
[0017] A preferred structure of the centrifugal dehydration device for pharmaceutical production is that a plurality of filter holes are arranged around the bottom of the side wall of the centrifugal barrel.
[0018] By adopting the above technical solution, the water at the bottom of the centrifugal barrel can seep out from the filter holes at the bottom of the side wall, thereby improving the drainage efficiency.

[0028] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0029] like Figure 1 and Figure 2 , a centrifugal dehydration device for pharmaceutical production, comprising a tank body 1, a cover 2, a centrifugal bucket 3 and a centrifuge 4. The centrifuge 4 can be a motor.
[0030] The upper end of the tank body 1 is open, and the cover 2 covers the upper end of the tank body 1. The cover 2 is provided with a feed port 21. The centrifugal bucket 3 is also open at the upper end. The centrifugal bucket 3 and the cover 2 are not connected.
[0031] like Figure 2, the centrifugal bucket 3 is arranged in the tank body 1. The side wall of the centrifugal bucket 3 is densely covered with a plurality of penetrating filter holes 31. The aperture of the filter hole 31 can be 0.5~2mm. The bottom surface of the centrifugal bucket 3 is a cone with an upward convex middle, and the middle is the highest, which is conducive to drainage. In order to further improve the drainage efficiency, the filter hole 31 can be arranged at the bottom of the side wall of the centrifugal bucket 3, that is, a plurality of the filter holes 31 are arranged in a circle at the bottom of the side wall of the centrifugal bucket 3, so that the water at the bottom of the centrifugal bucket 3 can seep out from the filter holes 31 at the bottom of the side wall, thereby improving the drainage efficiency.
[0032] The centrifuge 4 is located at the outer bottom of the centrifuge bucket 3. The rotating shaft of the centrifuge 4 is upwardly connected to the centrifuge bucket 3 to drive the centrifuge bucket 3 to rotate and remove water. The tank body 1 is provided with a drainage mechanism for receiving the water discharged from the filter hole 31 and discharging it outside the tank body 1.
[0033] This device uses a centrifugal method to dehydrate the medicine. Water is thrown out of the filter holes 31 of the centrifugal barrel 3 from the side. This method can continuously and stably dehydrate the medicine, and the water at the bottom of the centrifugal barrel 3 can also flow along the conical bottom to the side wall, reducing water accumulation at the bottom.
[0034] like Figure 1 , as for the drainage mechanism, it may include an annular drainage groove 11 with a V-shaped cross-section located at the inner bottom of the tank body 1. The drainage groove is seamlessly connected to the inner wall of the tank body 1 to collect water that is thrown toward the inner wall of the tank body 1 by the centrifugal bucket 3 and flows down along the inner wall of the tank body 1. The drainage groove is located below the side wall of the centrifugal bucket 3 and collects water thrown out with a smaller centrifugal force, so it can basically collect all the water thrown out by the centrifuge. The above V-shaped annular drainage groove 11 can receive the water thrown out by the centrifugal bucket 3, gather it at the bottom of the V-shaped structure, and discharge it by flowing at the bottom.
[0035] The drainage mechanism may further include a drainage pipe (not shown), which is connected to the bottom of the drainage trough, so that the water collected in the drainage trough can be discharged outside the tank body 1 through the drainage pipe.
[0036] like Figure 1In order to automatically further dry the dehydrated medicines, the cover 2 is designed to be provided with an air inlet 22, and the centrifugal dehydration device also includes a hot air system. The hot air system includes a hot air blower 5, a first air duct 6 and a second air duct 7. The hot air system may also include an air inlet duct, and a filter is provided at the entrance of the air inlet duct. The first air duct 6 and the second air duct 7 are respectively connected to the hot air blower 5. The first air duct 6 is connected to the air inlet 22. The second air duct 7 is connected to the interior of the tank body 1. The connection between the second air duct 7 and the tank body 1 is located above the drainage mechanism. The hot air generated by the hot air blower 5 passes through the side walls of the centrifugal barrel 3 and the upper opening of the centrifugal barrel 3 through the first air duct 6 and the second air duct 7, and performs hot air drying on the medicines in the centrifugal barrel 3 from the side and the front, respectively, to improve the drying efficiency of the device.
[0037] Because the second air duct 7 leads into the tank body 1, water ejected from the centrifugal bucket 3 may enter the interface between the second air duct 7 and the tank body 1. The tilt and shape of the second air duct 7 can be designed to prevent water from entering the second air duct 7. To further improve this, a solenoid valve 8 can be installed on the second air duct 7. During dehydration, the solenoid valve 8 is closed to prevent water from entering the second air duct 7 and instead enter the hot air blower 5. During drying, the solenoid valve 8 is opened, allowing hot air to enter the tank body 1 through the second air duct 7, drying the medicines in the centrifugal bucket 3.
[0038] The centrifugal dehydration device may further include a base 9. The tank body 1 is mounted on the base 9. The centrifuge 4 is mounted on the inner bottom of the tank body 1. The base 9 elevates the tank body 1 to facilitate drainage. The centrifuge 4 may be mounted on the upper surface or the lower surface of the base 9.
[0039] like Figure 1 and Figure 3 To accommodate the dehydration of pharmaceuticals with smaller particle sizes, the centrifugal dehydration device is designed to further include a filter paper cartridge 10. The filter paper cartridge 10 is tightly placed against the sidewalls of the centrifuge barrel 3, shielding all filter holes 31. The filter paper cartridge 10 also conforms to the inner bottom surface of the centrifuge barrel 3. The height of the filter paper within the centrifuge barrel 3 is less than the height of the sidewalls of the centrifuge barrel 3. For pharmaceuticals with smaller particle sizes, the filter paper cartridge 10 can prevent pharmaceutical particles from being ejected from the filter holes 31.
[0040] Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
