Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical powder drying technology, specifically to a boiling-type pharmaceutical powder drying box with a low-temperature container insulation layer. Background Technology

[0002] Drug drying refers to the process of removing moisture from drugs with high humidity through heating and ventilation to achieve a stable moisture content and quality requirements. The humidity of drugs has a significant impact on their quality and stability. Excessive humidity can cause drugs to become damp, moldy, or deteriorate, thereby affecting their activity and shelf life. Therefore, drug drying can reduce humidity, maintain drug quality, and extend their shelf life.

[0003] Chinese patent CN210320846U discloses a boiling-type pharmaceutical powder drying oven with a low-temperature container insulation layer. This oven increases the surface area of ​​the material in contact with air, and the forced airflow causes the sample powder to boil, thus improving the drying effect. Simultaneously, a breathable fabric is provided to support the material, and cleaning only requires replacing the fabric, improving the cleaning process and increasing operational efficiency. This solves the problems of poor drying effect at the bottom of the tray in existing powder drying ovens, the need for manual material turning, and the cumbersome cleaning after use. Furthermore, this drying equipment has a cooling function to ensure that the sample remains at a low temperature throughout the drying process, preventing damage to thermally unstable samples.

[0004] The above solution constructs a drying space using trays and breathable fabric, allowing the drug powder to undergo fluidized bed drying. However, because the hot air flows from bottom to top within the drying chamber, the vertically arranged drying spaces exhibit uneven drying, with the lower part having higher drying efficiency and the upper part having lower efficiency.

[0005] Therefore, this utility model provides a boiling-type pharmaceutical powder drying oven with a low-temperature container insulation layer to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a boiling-type pharmaceutical powder drying oven with a low-temperature container insulation layer, which solves the problem that the drying efficiency is higher in the lower part and lower in the upper part and uneven drying due to the upward flow of hot air in the drying oven.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A boiling-type pharmaceutical powder drying oven with a low-temperature container insulation layer includes a support base, an insulation box body fixedly connected to the support base, a partition plate fixedly connected inside the insulation box body, and the insulation box body divided into multiple drying spaces by the partition plate. Each drying space is equipped with a filter assembly. A hot air assembly is arranged below the support base. A material box is arranged between the insulation box body and the hot air assembly. The material box has a material trough, and a filter plate is installed in the material trough.

[0008] Preferably, the filter assembly includes a fixed plate fixedly connected to the drying space, a lifting plate is provided above the fixed plate, a filter bag is installed on the lifting plate, and the filter bag is connected to the fixed plate.

[0009] Preferably, a linkage rod is provided above the lifting plate, and the top of the linkage rod penetrates through the insulation box and extends to the top of the insulation box. A linkage plate is fixedly connected to the top of the linkage rod.

[0010] Preferably, the filter assembly further includes a support mounted on the insulation box, a motor mounted on the support, a gear mounted on the output shaft of the motor, and a rack fixedly connected to the linkage plate, with the rack meshing with the gear.

[0011] Preferably, an air collection box is provided above the insulation box, an exhaust pipe is fixedly connected to the air collection box, and two sets of collecting pipes are fixedly connected to the bottom surface of the air collection box. The end of the collecting pipe away from the air collection box is installed on the insulation box.

[0012] Preferably, the hot air assembly includes a hot air box, an air inlet pipe is fixedly connected to the hot air box, a heat dissipation groove is provided on the hot air box, and the air inlet pipe is connected to the material trough through the heat dissipation groove.

[0013] Preferably, an electric push rod is installed on the support base, and the telescopic end of the electric push rod is fixedly connected to the hot air box.

[0014] Preferably, a guide ring is fixedly connected to the hot air box, and the guide ring is slidably connected to the support base.

[0015] The beneficial effects of this utility model are as follows: 1. The hot air box is driven to rise by an electric push rod, so that the hot air box, material box and insulation box are tightly spliced ​​into an integral structure. The hot air delivered by the hot air blower enters the material box directly through the hot air box and heat dissipation trough. It can accurately carry the medicine powder on the filter plate into each drying space, reducing the heat loss of hot air during the transmission process. Moreover, after the hot air completes the drying process, it can quickly pass through the filter bag into the holding space and be discharged from the equipment. There is no need to bake the medicine powder at a continuous high temperature. This reduces unnecessary heat consumption and meets the requirements of low temperature drying. It effectively avoids the damage of heat-unstable medicines to continuous high temperature and ensures the activity and quality stability of the medicine.

[0016] 2. When the motor drives the gear to rotate, the meshing transmission between the gear and the rack on the linkage plate allows the two linkage plates to be in high and low positions respectively and switch between them. This, in turn, drives the lifting plate and the filter bag to rise and vibrate synchronously, causing the medicine powder in the filter bag to fall into the drying space. This not only ensures the filtration effect of the filter bag but also reduces the loss of medicine powder raw materials. Furthermore, each drying space is formed by a fixed plate and the filter bag to form an independent holding space. With the help of two sets of collecting pipes, the humid air in each drying space is uniformly collected and discharged into the air collection box, ensuring that the hot air circulates evenly in the multiple vertically distributed drying spaces. Ultimately, this ensures that all medicine powders achieve a consistent drying effect and improves the overall drying quality. Attached Figure Description

[0022] The following will refer to the attached reference. Figures 1 to 4The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0023] A boiling-type pharmaceutical powder drying oven with a low-temperature container insulation layer includes a support base 1. The support base 1 is designed with a heat preservation layer and a heat insulation layer to reduce heat loss. An insulation box body 2 is fixedly connected to the support base 1. A partition plate 11 is fixedly connected inside the insulation box body 2, and the insulation box body 2 is divided into multiple drying spaces by the partition plate 11. The partition plate 11 can divide the internal space of the insulation box body 2 into multiple drying spaces of the same cavity size.

[0024] Each drying chamber is equipped with a filter assembly, which includes a fixed plate 12 fixedly connected to the drying chamber, a lifting plate 14 above the fixed plate 12, a filter bag 13 installed on the lifting plate 14, and the filter bag 13 connected to the fixed plate 12.

[0025] The fixed plate 12 will form a containment space in the dry space, and the air in the dry space will be filtered by the filter bag 13 and stored in the containment space.

[0026] In this embodiment, a linkage rod 21 is provided above the lifting plate 14, and the top of the linkage rod 21 passes through the insulation box 2 and extends to the top of the insulation box 2. A linkage plate 22 is fixedly connected to the top of the linkage rod 21.

[0027] This application has at least two linkage plates 22, which are respectively in a high position and a low position. That is, the two fixed plates 12 can lift and vibrate the filter bags 13 in at least two accommodating spaces, so that the powder filtered out in the filter bags 13 is discharged into the drying space.

[0028] In this embodiment, the filter assembly also includes a support 18 installed on the insulation box 2, a motor 19 installed on the support 18, a gear 20 installed on the output shaft of the motor 19, and a rack 23 fixedly connected to the linkage plate 22, and the rack 23 meshes with the gear 20.

[0029] The output shaft of motor 19 drives gear 20 to rotate. With the meshing of rack 23 and gear 20, the two linkage plates 22 on both sides of gear 20 can be in low and high positions respectively. The meshing motion of rack 23 driven by gear 20 enables the two linkage plates 22 to switch between low and high positions.

[0030] In this embodiment, an air collection box 16 is provided above the insulation box 2, and an exhaust pipe 17 is fixedly connected to the air collection box 16. Two sets of collecting pipes 15 are fixedly connected to the bottom surface of the air collection box 16, and the end of the collecting pipe 15 away from the air collection box 16 is installed on the insulation box 2.

[0031] Moisturized air in the dry space is filtered by the filter bag 13 and stored in the containment space. It is then collected in the air collection box 16 through the collection pipe 15 and finally discharged to the subsequent filtration equipment through the exhaust pipe 17.

[0032] In this embodiment, a hot air assembly is provided below the support base 1. The hot air assembly includes a hot air box 4, an air inlet pipe 5 is fixedly connected to the hot air box 4, a heat dissipation groove 8 is provided on the hot air box 4, and the air inlet pipe 5 is connected to the material trough 9 through the heat dissipation groove 8.

[0033] The air inlet pipe 5 is connected to the hot air blower, which can deliver hot air with heat through the hot air box 4 to the heat dissipation tank 8, and finally from the heat dissipation tank 8 to the material tank 9.

[0034] In this embodiment, a guide ring 7 is fixedly connected to the hot air box 4, and the guide ring 7 is slidably connected to the support base 1. The guide ring 7 improves the stability of the hot air box 4 during lifting and moving.

[0035] In this embodiment, a material box 6 is provided between the heat insulation box 2 and the hot air assembly. The material box 6 has a material trough 9, and a filter plate 10 is installed in the material trough 9. Workers can pour the medicine powder into the filter plate 10 through the opening of the material trough 9. The filter plate 10 is made of breathable material, which can block the medicine powder, while air can penetrate the filter plate 10 and enter the area above the filter plate 10.

[0036] In this embodiment, an electric push rod 3 is installed on the support base 1. The telescopic end of the electric push rod 3 is fixedly connected to the hot air box 4. The electric push rod 3 drives the hot air box 4 to move upward, so that the hot air box 4 can be pressed against the material box 6 and the material box 6 can be moved upward. The heat insulation box 2, the hot air box 4 and the material box 6 form an integral structure. After the hot air blows on the drug powder, the hot air carries the drug powder to each drying space for boiling drying. The heat will quickly flow from the drying space to the receiving space, and then be discharged to the outside through the receiving space. There is no need to continuously dry the drug powder in the support base 1 at high temperature.
