Abstract

This utility model relates to the field of veterinary drug powder production technology, and in particular to a drying device for veterinary drug powder production. The device includes a sealing cap, a heat-conducting cylinder, a shell, a first internal thread, a feed pipe, a pipe cap, a bearing, a rotating shaft, a motor, multiple stirring shafts, multiple hot air blowers, an adjustable exhaust assembly, and a first external thread. By placing the powder inside the heat-conducting cylinder, a drying chamber is formed between the heat-conducting cylinder and the shell. Hot air is introduced into the drying chamber by the hot air blowers, and the adjustable exhaust assembly is located on the top of the other side of the shell to exhaust gas. This structural design allows the hot air to circulate fully in the drying chamber, and the heat-conducting cylinder can evenly conduct heat to the internal powder.

It allows for more efficient heat exchange between the hot air and the powder, avoiding the situation where the hot air only circulates in the area above the powder and cannot fully act on the powder at the bottom, effectively improving drying efficiency.

Description

Technical Field

[0001] This utility model relates to the field of veterinary drug powder production technology, and in particular to a drying device for veterinary drug powder production. Background Technology

[0002] Veterinary drug powders are dry, powdered veterinary drug preparations made by pulverizing and mixing one or more drug raw materials. They are commonly used for the prevention, treatment, or growth promotion of livestock and poultry diseases. Appropriate excipients may be added during the preparation process to improve solubility, stability, or flowability, facilitating administration via drinking water, feed mixing, or direct oral administration.

[0003] Existing patent CN217131706U discloses a powder drying device for veterinary drug production and processing, including a shell and a top cover. The top cover is disposed on the upper surface of the shell. Through slots are provided on both sides of the shell. A heating chamber and a filter chamber are fixedly installed on both sides of the shell at corresponding positions in the through slots. An exhaust port is provided on the side of the filter chamber away from the shell. A motor is fixedly installed at the bottom of the shell, and the output shaft of the motor extends to the inside of the shell. The output shaft of the motor is driven by a stirring shaft. This powder drying device for veterinary drug production and processing, by setting up a hot air conveying component, uses a heating lamp to heat the surrounding air. An air pump delivers the gas to the inside of the heating chamber, increasing the air pressure inside the heating chamber. The higher-temperature gas inside the heating lamp enters the inside of the shell through the through slots, thereby drying the powder inside the shell. Some moisture is discharged to the outside of the shell along with the air through the filter chamber and the exhaust port, avoiding the problem of excessive moisture in the air inside the shell affecting the drying speed of the veterinary drug powder.

[0004] However, in the aforementioned prior art, since the powder is located at the bottom of the casing, while the exhaust port and air inlet are arranged opposite each other and located above the powder, the heat exchange is insufficient, resulting in low drying efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a drying device for the production of veterinary drug powder, which aims to solve the technical problem in the prior art where the powder is located at the bottom of the shell, while the exhaust port and air inlet are arranged opposite to each other and located above the powder, resulting in insufficient heat exchange and thus low drying efficiency.

[0006] To achieve the above objectives, this utility model employs a drying device for veterinary drug powder production, comprising a sealing cap, a heat-conducting cylinder, and a housing. The inner side of the sealing cap has a first internal thread, and a feed pipe is disposed above the sealing cap. A pipe cap is threaded onto the feed pipe. A rotating shaft is rotatably disposed in the middle of the sealing cap via a bearing, and the rotating shaft is driven by a motor. Multiple stirring shafts are disposed on the rotating shaft. Multiple hot air blowers are disposed at the bottom of one side of the housing, and an adjustable exhaust assembly is disposed at the top of the other side of the housing. The outer side of the housing has a first external thread. The sealing cap is threadedly connected to the housing and covers the top of the housing, with the first external thread located at the first internal thread. The heat-conducting cylinder is disposed inside the housing, and a drying chamber is formed between the heat-conducting cylinder and the housing. The sealing cap also abuts against the top of the heat-conducting cylinder, and the multiple stirring shafts extend into the heat-conducting cylinder. The discharge end of the feed pipe faces the feed end of the heat-conducting cylinder.

[0007] The heat-conducting cylinder has multiple spacer rods at its lower part, and the inner bottom of the outer shell has multiple circular grooves, with the spacer rods inserted into the corresponding circular grooves.

[0008] The sealing cover has a sealing ring below it, and the outer shell has a sealing groove above it, with the sealing ring located inside the sealing groove.

[0009] The adjustable exhaust assembly includes an adjustable exhaust cover and an exhaust pipe. The adjustable exhaust cover has an exhaust port on its outer side and a second internal thread on its inner side. One end of the adjustable exhaust cover has a sealing cavity. The exhaust pipe has a second external thread on its outer side. The adjustable exhaust cover is threadedly connected to the exhaust pipe and covers the exhaust pipe. The second external thread is located at the second internal thread. The gas in the exhaust pipe is discharged through the exhaust port. The exhaust pipe is connected to the outer casing and is located on the top of the other side of the outer casing.

[0010] The drying equipment for producing veterinary drug powder also includes multiple pins, multiple upper pin seats are provided on the outer side of the sealing cover, and multiple lower pin seats are provided on the outer side of the outer shell. The upper pin seats and the lower pin seats are arranged symmetrically, and the multiple pin seats are respectively inserted between the corresponding upper pin seats and the corresponding lower pin seats.

[0011] This utility model discloses a drying device for producing veterinary drug powder, comprising a sealing cap, a heat-conducting cylinder, a shell, a first internal thread, a feed pipe, a pipe cap, a bearing, a rotating shaft, multiple stirring shafts, multiple hot air blowers, an adjustable exhaust assembly, and a first external thread. The powder is placed inside the heat-conducting cylinder, which is located inside the shell, forming a drying chamber between them. The hot air blowers, located at the bottom of one side of the shell, introduce hot air into the drying chamber. The adjustable exhaust assembly, located at the top of the other side of the shell, exhausts gas. This structural design ensures that the hot air in the drying chamber... The heat-conducting cylinder allows for full airflow, enabling it to evenly conduct heat to the internal powder. This changes the traditional layout where the powder is at the bottom and the air inlet and outlet are at the top, which is not conducive to heat exchange. It allows for more efficient heat exchange between the hot air and the powder, avoiding the situation where the hot air only circulates in the area above the powder and cannot fully act on the powder at the bottom. This effectively improves the drying efficiency. In this way, it solves the technical problem that the powder is located at the bottom of the shell, while the air inlet and outlet are arranged opposite each other and located above the powder, resulting in insufficient heat exchange and thus low drying efficiency.

Multiple stirring shafts 9 are provided on the rotating shaft 7. Multiple hot air blowers 10 are provided on the bottom of one side of the shell 3, and a heat exchanger is provided on the top of the other side of the shell 3. An adjustable exhaust assembly is provided. The outer side of the housing 3 has a first external thread 11. The sealing cover 1 is threadedly connected to the housing 3 and covers the top of the housing 3. The first external thread 11 is located at the first internal thread 4. The heat-conducting cylinder 2 is disposed inside the housing 3, and a drying chamber is formed between the heat-conducting cylinder 2 and the housing 3. The sealing cover 1 also abuts against the top of the heat-conducting cylinder 2. A plurality of stirring shafts 9 extend into the heat-conducting cylinder 2. The discharge end of the feed pipe 5 is disposed towards the feed end of the heat-conducting cylinder 2.

[0020] In this embodiment, the sealing cap 1 and the outer shell 3 are connected by threads, which facilitates disassembly and assembly, and makes it easy to maintain, clean, and replace internal components of the equipment. The feed pipe 5 and the threaded pipe cap 6 above the sealing cap 1 facilitate the addition of powder into the heat-conducting cylinder 2, while effectively preventing external impurities from entering and ensuring the purity of the powder. The hot air blower 10 is provided at the bottom of the outer shell 3, and the adjustable exhaust assembly is provided at the top. It cooperates with the drying chamber formed by the heat-conducting cylinder 2 and the outer shell 3 to allow hot air to circulate fully in the drying chamber and improve heat exchange efficiency. The rotating shaft 7 and multiple stirring shafts 9 are rotatably mounted in the middle of the sealing cap 1 through the bearing, and the stirring shafts 9 extend into the heat-conducting cylinder 2 to stir the powder during the drying process, ensuring that the powder is heated evenly and avoiding insufficient drying in some areas, thus effectively improving the drying quality and efficiency.

[0021] Furthermore, a plurality of spacer rods 12 are provided below the heat-conducting cylinder 2, and a plurality of circular grooves 13 are provided at the inner bottom of the outer shell 3, with the spacer rods 12 inserted into the corresponding circular grooves 13.

[0022] In this embodiment, the spacer rod 12 provides stable support and positioning for the heat-conducting cylinder 2, while also forming the drying cavity between the heat-conducting cylinder 2 and the outer shell 3, facilitating the flow of hot air.

[0023] Furthermore, a sealing ring 14 is provided below the sealing cover 1, and a sealing groove 15 is provided above the outer shell 3, with the sealing ring 14 located within the sealing groove 15.

[0024] In this embodiment, this sealing design effectively prevents hot air leakage and external impurities from entering the equipment.

[0025] Furthermore, the adjustable exhaust assembly includes an adjustable exhaust cover 16 and an exhaust pipe 17. The adjustable exhaust cover 16 has an exhaust port 18 on its outer side and a second internal thread 19 on its inner side. One end of the adjustable exhaust cover 16 has a sealing cavity 20. The exhaust pipe 17 has a second external thread 21 on its outer side. The adjustable exhaust cover 16 is threadedly connected to the exhaust pipe 17 and covers the exhaust pipe 17. The second external thread 21 is located at the second internal thread 19. The gas in the exhaust pipe 17 is discharged through the exhaust port 18. The exhaust pipe 17 is connected to the outer casing 3 and is located on the top of the other side of the outer casing 3.

[0026] In this embodiment, the operator can flexibly adjust the size of the exhaust port 18 by rotating the adjustable exhaust cover 16 to achieve precise control of the exhaust volume. During the drying process, the exhaust volume can be adjusted in a timely manner according to the actual situation such as the humidity of the powder and the drying speed, so as to better control the airflow and temperature during the drying process and improve the drying effect. At the same time, when the adjustable exhaust cover 16 moves to the sealing cavity 20, a sealed state is formed between the adjustable exhaust cover 16 and the exhaust pipe 17.

[0027] Furthermore, the drying equipment for producing veterinary drug powder also includes multiple pins 22, multiple upper pin seats 23 are provided on the outer side of the sealing cover 1, and multiple lower pin seats 24 are provided on the outer side of the outer shell 3.

[0028] In this embodiment, the pin 22 is provided to prevent the sealing cover 1 from rotating with the rotating shaft 7, thereby improving stability.

[0029] When using this invention, firstly, open the tube cap 6 and add the veterinary drug powder to be dried into the heat-conducting cylinder 2 through the feed pipe 5. Because the discharge end of the feed pipe 5 faces the feed end of the heat-conducting cylinder 2, the powder can smoothly enter the heat-conducting cylinder 2. After adding the powder, tighten the tube cap 6. Next, turn on multiple hot air blowers 10. The hot air blowers 10 introduce hot air into the drying chamber. The heat-conducting cylinder 2 is heated and the heat is conducted to the powder inside. At the same time, the motor 8 drives the rotating shaft 7 to drive multiple stirring shafts 9 to rotate inside the heat-conducting cylinder 2. The powder is stirred to ensure uniform heating. Moisture generated during the drying process is discharged through the exhaust pipe 17. The adjustable exhaust cover 16, which is threaded onto the exhaust pipe 17, can adjust the size of the exhaust port 18 according to the actual drying situation to control the exhaust volume. After drying is completed, the hot air blower 10 is turned off, and the sealing cover 1 is unscrewed from the outer shell 3 through the threaded connection structure. At the same time, multiple stirring rods are removed. Finally, the heat-conducting cylinder 2 is removed from the outer shell 3 as a whole. At this time, the dried veterinary drug powder is taken out, completing the entire drying operation.

[0030] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
