Description

Technical Field

[0001] This utility model relates to the field of drying technology, and in particular to an electric heating forced-air drying oven. Background Technology

[0002] Electric heating forced-air drying ovens use electric heating to dry items, and are widely used in various industries such as chemical, pharmaceutical, and food processing. In pharmaceutical production, electric heating forced-air drying ovens are often used to dry granular drugs.

[0003] In existing technologies, granular pharmaceutical preparations are typically dried on a tray within an electric heating drying oven. However, this method, due to the fixed positions of the tray and the blower, results in a unidirectional flow of hot air, leading to inconsistent temperatures across the drug and uneven heating of the drug surface. Currently, some electric heating drying ovens utilize rotatable trays for drying, ensuring more uniform heating and drying of the material. For example, Chinese patent CN201922019171.X discloses an auxiliary rotating electric heating drying oven. This oven features a fixed rod and a circular shelf. The circular shelf is connected to the fixed rod via an L-shaped fixing plate and bolts, forming a detachable and removable structure for easy cleaning or replacement. The circular shelf on the fixed rod rotates under the influence of a drive motor, accelerating the drying time and ensuring more uniform heating.

[0004] However, in the aforementioned patent, the installation and disassembly of the circular shelf and the fixing rod are quite troublesome, making it inconvenient to remove the materials from the circular shelf. Furthermore, after drying, the temperature inside the drying chamber is high, making it inconvenient to remove the circular shelf and take out the materials from it. In addition, moisture generated by the materials on the upper circular shelf during the drying process can easily drip onto the materials on the lower circular shelf, which can easily lead to cross-contamination of materials on different circular shelves.

[0010] An electric heating blower assembly is located on the top of the main body to input hot air into the drying chamber.

[0011] Furthermore, it also includes a pressure relief pipe, which is installed on the body and connected to the drying chamber.

[0012] Furthermore, the bottom of the placement net is provided with an installation shaft with a polygonal prism structure, and an installation post is provided in the middle of the groove, the installation post having an installation groove that matches the installation shaft.

[0013] Furthermore, the bottom end of the mounting post extends into the transmission cavity inside the barrier plate and is connected to the rotating shaft, which is connected to the output end of the drive assembly.

[0014] Furthermore, the drive assembly includes a drive motor and a number of drive shafts equal to the number of the barrier plates. A drive cavity is provided on the outer side of the sealing door, and a transmission cavity is provided inside the barrier plate. One end of the drive shaft is rotatably mounted on the wall of the transmission cavity, and the other end extends out of the transmission cavity and into the drive cavity. A drive gear is installed on the drive shaft located in the transmission cavity, and the drive gear meshes with a driven gear fixed at the bottom end of the rotating shaft. The drive shafts located inside the drive cavity are connected by a transmission chain, and one of the drive shafts is connected to the output shaft of the drive motor.

[0015] Furthermore, the electric heating blower assembly includes a blower and an electric heating tube. A hot air chamber is provided on one side of the main body. Several hot air holes are opened on the wall of the drying chamber to connect the drying chamber and the hot air chamber. The hot air chamber is connected to the heating chamber through a hot air pipe. The electric heating tube is installed in the heating chamber. The air outlet of the blower is connected to the heating chamber.

[0016] Furthermore, a filter box for filtering air is provided between the heating chamber and the blower.

[0017] Furthermore, a drain outlet is provided on one side of the groove.

[0018] The beneficial effects of this utility model are as follows: The drying chamber of the main body provides a drying environment; the sealing door serves to close or open the drying chamber, preventing excessive heat loss; the placement component is used to place the material to be dried; the electric heating blower assembly, located on the top of the main body, is used to input hot air into the drying chamber to dry the material on the placement component; the placement component is mounted on the sealing door and rotates with the sealing door. When the sealing door closes the main body to seal the drying chamber, the placement component is located inside the drying chamber. This design allows the placement component to enter the drying chamber when the sealing door is closed, and to exit the drying chamber simultaneously when the sealing door is opened. This eliminates the need for operators to use additional tools to remove the placement component from the drying chamber, and avoids the need to reach into the drying chamber to retrieve the material, preventing burns to operators and improving safety. The placement component is located outside the drying chamber, which facilitates rapid cooling of the dried material in the external environment and makes material placement and removal more convenient as space is not a constraint. The placement mesh of the placement component allows air to circulate from the bottom, enabling the bottom surface of the material to be heated and dried as well, thus improving the overall drying efficiency. The drive component provides the rotational power source, driving the placement mesh to rotate smoothly on the baffle plate, thereby rotating the material on the placement mesh and ensuring that the material is exposed to airflow from all sides, thus ensuring that the material is effectively dried from all sides, greatly improving the overall drying efficiency and uniformity. The baffle plate provides support for the placement mesh, and the recessed grooves on the upper surface of the baffle plate are used to collect water droplets and liquid droplets falling from the material on the placement mesh, effectively preventing the material on the lower placement mesh from being re-wetted and affecting the drying efficiency.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0027] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0028] See Figures 1 to 6 An electric heating drying oven includes a main body 100, a sealing door 200, a placement assembly 300, and an electric heating air assembly 500.

[0029] The main body 100 includes a drying chamber 110, which provides a drying environment. Notably, the drying chamber 110 has a heat dissipation vent to discharge water vapor generated during the drying process of pharmaceutical materials. It also includes a pressure relief pipe 120, which is installed on the main body 100 and connected to the drying chamber 110. The pressure relief pipe 120 is used to discharge gas when the internal pressure of the drying chamber 110 is high, preventing the main body 100 from exploding and ensuring safety.

[0030] A sealing door 200 is hinged to the front opening of the main body 100. The sealing door 200 serves to close or open the drying chamber 110 to prevent excessive heat loss. The sealing door 200 is a prior art product, and the connection technology between the sealing door 200 and the main body 100, as well as the closing and opening technology, are all prior art. A placement component 300 is provided on the side of the sealing door 200 facing the main body 100, and the sealing door 200 covers the main body 100. The placement component 300 is located inside the drying chamber 110 and is used to place the material to be dried.

[0031] The placement assembly 300 includes multiple placement units 310. Each placement unit 310 includes a baffle plate 320 and a placement net 330. The baffle plate 320 is fixed to the sealing door 200, and its surface is recessed with a groove 321. The placement net 330 is rotatably mounted on the baffle plate 320. The sealing door 200 is provided with a drive assembly 400 for driving the placement net 330 to rotate. It can be understood that the arrangement of multiple placement units 310 allows multiple placement nets 330 to simultaneously hold materials to be dried, thereby improving drying efficiency.

[0032] An electric heating blower assembly 500 is disposed on the top of the main body 100 to input hot air into the drying chamber 110 to dry the material on the placement mesh 330 of the placement assembly;

[0033] Specifically, the placement component 300 is mounted on the sealing door 200 and rotates with the sealing door 200. When the sealing door 200 closes onto the body 100 to seal the drying chamber 110, the placement component 300 is located inside the drying chamber 110. This design allows the placement component to enter the drying chamber 110 simultaneously with closing the sealing door 200, and to exit the drying chamber 110 simultaneously with opening the sealing door 200. This eliminates the need for operators to use additional tools to remove the placement component 300 from the drying chamber 110, and avoids the need to reach into the drying chamber 110 to retrieve materials, preventing burns to operators and improving safety. Furthermore, the placement component 300's location outside the drying chamber 110 facilitates rapid cooling of the dried material in the external environment and makes loading and unloading easier. The material handling is not limited by space, making the loading and unloading of materials more convenient. The placement component 300 and the placement net 330 allow ventilation on the bottom surface of the material, enabling the bottom surface to be heated and dried, thus improving the overall drying efficiency. The drive component 400 provides a rotational power source, driving the placement net 330 to rotate smoothly on the baffle plate 320, thereby rotating the material on the placement net 330. This ensures that the material is exposed to airflow from all sides, guaranteeing effective drying from all sides and greatly improving the overall drying efficiency and uniformity. The baffle plate 320 provides support for the placement net 330, while the recessed grooves 321 on the upper surface of the baffle plate 320 receive water droplets and liquid droplets falling from the material on the placement net 330, effectively preventing the material on the lower placement net 330 from being re-wetted and affecting the drying efficiency.

[0034] In some embodiments, the bottom of the placement net 330 is provided with an installation shaft 331 in the form of a polygonal prism structure, and an installation post 322 is provided in the middle of the groove 321. The installation post 322 has an installation groove 323 that matches the installation shaft 331. The quick installation and disassembly of the placement net 330 is realized through the cooperation between the installation shaft 331 and the installation groove 323.

[0035] In some embodiments, the bottom end of the mounting post 322 extends into the transmission cavity 324 inside the barrier plate 320 and is connected to the rotating shaft 340, which is connected to the output end of the drive assembly 400. Further, the drive assembly 400 includes a drive motor 410 and a number of drive shafts 420 equal to the number of barrier plates 320. A drive cavity 210 is provided on the outer side of the sealing door 200. One end of each drive shaft 420 is rotatably mounted on the wall of the transmission cavity 324, and the other end extends out of the transmission cavity 324 and into the drive cavity 210. A drive gear 421 is mounted on the drive shaft 420 located within the transmission cavity 324, and the drive gear 421 meshes with a driven gear 341 fixed at the bottom end of the rotating shaft 340. The drive shafts 420 located within the drive cavity 210 are connected via a transmission chain, and one of the drive shafts 420 is connected to the output shaft of the drive motor 410, which is a prior art product. In practical use, the drive motor 410 drives the transmission shaft 420, which in turn drives the other transmission shafts 420 to rotate synchronously under the transmission of the transmission chain. At the same time, with the cooperation of the drive gear 421 and the driven gear 341, the rotating shaft 340 rotates, thereby driving the placement net 330 to rotate.

[0036] In some embodiments, the electric heating blower assembly 500 includes a blower 510 and an electric heating tube 520. A hot air chamber 130 is provided on one side of the main body 100.
