Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an oven for the production of Lecadipine hydrochloride tablets. Background Technology

[0002] During the production of lercanidipine hydrochloride, the tablets need to be dried to ensure that they do not get damp and thus guarantee the quality of the drug.

[0003] A hot air circulating drying oven for tablets, with publication number CN221172765U, includes a box body and a circulating air duct integrated into the inner wall of the box body. The inner walls on opposite sides of the box body are provided with multiple pairs of mounting parts, and drying plates are installed through the mounting parts. Each pair of mounting parts is distributed at different heights so that the installed drying plates form an angle of α. A layer of tablets can be automatically formed on the drying plates, and the drying speed is relatively fast. However, most of these ovens require opening the door and then removing the drying trays from inside the drying chamber, and then repositioning the drying trays inside the drying chamber. Due to the high temperature inside the oven, personnel's hands can easily come into contact with the inner wall of the drying chamber and get injured, resulting in low safety. Utility Model Content

[0005] As a further description of the above technical solution: the box body is provided with a control panel, the outside of the box door is provided with a handle, and the bottom of the box body is provided with casters.

[0006] As a further description of the above technical solution: the heating mechanism includes a housing, an air outlet assembly is provided on the top of the housing, an electric heating wire is installed inside the housing and on the side near the air outlet assembly, a fan is provided on one side of the electric heating wire, and an air inlet pipe is provided on one side of the housing.

[0007] As a further description of the above technical solution: an installation plate is connected to the inner side of the door, a first limiting groove is provided on the installation plate, and a first sliding plate adapted to the first limiting groove is provided on one side of the sealing plate.

[0008] As a further description of the above technical solution: a second limiting groove is provided on one side of the sealing plate, and a second sliding plate adapted to the second limiting groove is provided on one side of the baking tray.

[0009] As a further description of the above technical solution: the air outlet assembly includes a conveying pipe, and multiple air outlet pipes are equally spaced on one side of the conveying pipe.

[0010] As a further description of the above technical solution: an exhaust pipe is provided on one side of the box, and both the exhaust pipe and the intake pipe are equipped with filters.

[0011] The above technical solution has the following advantages or beneficial effects:

[0012] This invention allows the drying tray to be pulled out along with the door by pulling the handle outwards, using the moving wheels and support wheels for movement. This facilitates the removal of the drying tray and its contents, and makes it easy to rearrange the tablets to be dried. It also prevents personnel from accidentally touching the inner wall of the drying chamber and getting injured, thus improving the safety of the device. The sliding connection between the first sliding plate and the first limiting groove makes it easy to install and remove the sealing plate and the mounting plate, allowing for the complete replacement of the sealing plate and drying tray. This enables quick replacement, reduces heat loss inside the chamber, and improves overall flexibility. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figure 1-4 As shown, the present invention discloses an oven for producing Lecadipine hydrochloride tablets, comprising: a box body 1, wherein a drying chamber 2 is provided inside the box body 1; a box door 3, wherein the box door 3 is located on one side of the box body 1, and a sealing plate 4 is provided on the inner side of the box door 3; drying trays 5, wherein multiple drying trays 5 are detachably connected to the sealing plate 4; a heating mechanism 6, wherein the heating mechanism 6 is connected to the box body 1; a moving wheel 7 is provided below the box door 3; a base plate 8 is connected below the sealing plate 4; and a support wheel 9 is provided below the base plate 8.

[0023] In this embodiment, the tablets to be dried are laid flat in the drying tray 5 and dried in the drying chamber 2. After drying, the door 3 is pulled outward by the handle 11 and moved by the moving wheels 7 and support wheels 9. The drying tray 5 can be pulled out along with the door 3, making it easy to remove the drying tray 5 and the medicine inside, and to easily reposition the tablets to be dried. This avoids accidental contact between the hands and the inner wall of the drying chamber 2, thus improving the safety of the device.

[0024] like Figure 1 and Figure 2As shown, specifically, the box body 1 is equipped with a control panel 10, the outside of the box door 3 is equipped with a handle 11, the bottom of the box body 1 is equipped with casters 12, and the side of the box door 3 can be equipped with a fixing block; the control panel 10 can control the device to work, and the handle 11 can be used to push and pull the box door 3.

[0025] like Figure 1 and Figure 3 As shown, specifically, the heating mechanism 6 includes a housing 61, an air outlet assembly 62 is arranged on the top of the housing 61, an electric heating wire 63 is installed inside the housing 61 and on the side near the air outlet assembly 62, a fan 64 is arranged on one side of the electric heating wire 63, an air inlet pipe 65 is arranged on one side of the housing 61, and the air outlet assembly 62 includes a delivery pipe 66, with multiple air outlet pipes 67 evenly spaced on one side of the delivery pipe 66. When the fan 64 operates, air can be drawn into the housing 61, heated by the electric heating wire 63, and then enter the air outlet assembly 62. By evenly arranging multiple air outlet pipes 67 on one side of the delivery pipe 66, the air heated by the electric heating wire 63 is evenly sprayed into the interior of the housing 1, achieving uniform heating and effectively avoiding the problem of uneven drying.

[0026] like Figure 2 and Figure 4 As shown, specifically, an installation plate 13 is connected to the inner side of the door 3. A first limiting groove 14 is provided on the installation plate 13. A first sliding plate 15 that matches the first limiting groove 14 is provided on one side of the sealing plate 4. The sliding connection between the first sliding plate 15 and the first limiting groove 14 makes it easy to install and remove the sealing plate 4 and the installation plate 13, allowing the sealing plate 4 and the baking tray 5 to be replaced as a whole, achieving quick replacement, reducing heat loss inside the box 1, and improving overall flexibility.

[0027] like Figure 2 and Figure 4 As shown, specifically, a second limiting groove 16 is provided on one side of the sealing plate 4, and a second sliding plate 17 adapted to the second limiting groove 16 is provided on one side of the baking tray 5; the second sliding plate 17 is slidably connected to the second limiting groove 16, which makes it convenient to install and remove the baking tray 5 on the sealing plate 4, facilitates the replacement and maintenance of the baking tray 5, and enhances the practicality of the device.

[0028] like Figure 1 and Figure 3 As shown, specifically, an exhaust pipe 18 is provided on one side of the housing 1, and a filter screen 19 is provided inside both the exhaust pipe 18 and the air inlet pipe 65; the filter screen 19 can filter the air entering through the air inlet pipe 65 and the air exiting through the exhaust pipe 18, so as to prevent external impurities from being sucked into the housing 1.

[0029] Working principle: The staff lays the tablets to be dried flat in the drying tray 5 and dries them in the drying chamber 2. After drying, the staff only needs to pull the door 3 outward by the handle 11. The tray 5 can be pulled out along with the door 3 by moving the wheels 7 and supporting wheels 9. This makes it easy to remove the tray 5 and the medicine inside, and to put the tablets to be dried back in place. This avoids the staff's hands from accidentally touching the inner wall of the drying chamber 2 and getting injured, thus improving the safety of the device.
