Description

Technical Field

[0001] This utility model belongs to the technical field of adamantane hydrochloride, and in particular, it is a cold air drying device for the production of adamantane hydrochloride. Background Technology

[0002] Amantadine hydrochloride can inhibit viral penetration into host cells and affect viral uncoating, thus inhibiting its reproduction and playing a role in the treatment and prevention of viral infections. The production process of amantadine hydrochloride requires the use of a cold air drying device. Existing cold air drying devices need to filter the output air to prevent impurities from being present, thereby improving the production and processing quality of amantadine hydrochloride. At the same time, the surface of the filter screen needs to be cleaned to prevent it from being blocked. However, the disassembly and cleaning of the filter screen has not been considered, which causes the impurities cleaned on the surface of the filter screen to block the filter screen again, reducing the cold air drying effect of the device on amantadine hydrochloride.

[0003] In related technologies, a search revealed a Chinese patent document (authorization announcement number CN222143680U) for a cold air drying device for the production of adamantane hydrochloride, which includes a movable platform with symmetrically distributed support seats fixed to the bottom side wall of the movable platform. This utility model, through the combination of the movable platform, movable wheels, air blowing platform, air blowing channel and air blowing mechanism, can quickly perform cold air drying on products in different positions, and can automatically separate and filter dust and other impurities in the cold air, reducing the impact on the product during the cold air drying process. However, this device does not consider disassembling and cleaning the filter screen, causing the debris cleaned on the surface of the filter screen to clog the filter screen again, reducing the cold air drying effect of the device on adamantane hydrochloride. Utility Model Content

[0004] The purpose of this invention is to provide a cold air drying device for the production of adamantane hydrochloride, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold air drying device for the production of adamantane hydrochloride, comprising:

[0006] A drying oven for cold air drying of adamantane hydrochloride has a hollow side and a cold air fan for cold air drying of adamantane hydrochloride is installed on the outer wall of the drying oven.

[0007] The filter assembly includes an electric push rod and a H-shaped movable frame. The movable frame has two inner cavities, each connected to a limit frame. The side of the limit frame abuts against the filter frame. A filter screen is connected to the inner wall of the filter frame. Two C-shaped pull plates are provided on the side of the filter screen away from the limit frame. The centrifugal side of the two pull plates is connected and fixed to the filter frame. Two symmetrically arranged limit plates are connected to the side of the movable frame. One of the limit plates has an L-shaped connecting plate at its upper part. The end face of the connecting plate and its inner wall are respectively connected to the movable end of the movable frame and the electric push rod.

[0008] Preferably, both inner walls of the drying oven are slidably connected to the movable frame, and the upper part of the fixed end of the electric push rod abuts against two arc-shaped mounting plates.

[0009] Preferably, the bottom surfaces of both mounting plates are connected to the drying chamber by bolts, and a collection component is provided at the bottom of the drying chamber.

[0010] Preferably, the collection assembly includes two support plates and two L-shaped support frames, the top surfaces of which are connected to the drying chamber.

[0011] Preferably, the inner bottom wall of the support frame abuts against the support plate, and a collection box is connected to the adjacent side of the two support plates.

[0012] Preferably, a rubber frame is connected to the top surface of the collection box, and the top surface of the rubber frame makes sliding frictional contact with the drying box.

[0013] Preferably, the bottom wall of the drying oven is provided with a through groove that matches the inner cavity of the rubber frame, and both ends of the collection box are provided with abutment plates and limiting bolts.

[0014] Preferably, both limiting bolts are threadedly connected to the collection box, and the side of the abutment plate has a through groove for the threaded part of the limiting bolt to be inserted.

[0015] Preferably, the two abutting plates abut against the drying box on their adjacent sides, and four support rods are connected to the bottom surface of the drying box.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0017] This cold air drying device for the production of adamantane hydrochloride moves the drying chamber to a designated position, with one side of the drying chamber opening facing the adamantane hydrochloride to be dried. A cold air blower provides cold air to dry the adamantane hydrochloride. During the cold air drying process, external impurities easily mix into the adamantane hydrochloride. A filter screen is installed to filter these impurities, but the surface of the filter screen is easily clogged by impurities. Direct cleaning will result in repeated clogging of the filter screen. An electric push rod provides power, causing the moving frame to move laterally during transmission, allowing the two filter screens to alternately extend into the drying chamber for filtration. Pulling the pull plate extending to the outside of the drying chamber allows for the removal of the filter frame and filter screens, enabling surface cleaning of the filter screens and improving the cold air drying effect on the adamantane hydrochloride.

[0018] This cold air drying device for the production of amantadine hydrochloride addresses the issue of debris entering the drying chamber via a cold air blower. If the debris does not adhere to the filter screen, it may remain inside the drying chamber and clog the filter screen again. The debris inside the drying chamber extends through a channel into a collection box for collection and storage. The device allows two abutment plates to rotate, releasing them from the drying chamber and enabling the collection box to move laterally. This allows the two support plates to detach from the two support frames, facilitating the disassembly of the collection box and cleaning out the collected debris. This prevents residual debris inside the drying chamber from clogging the filter screen again, thus improving the cold air drying effect on amantadine hydrochloride. Attached Figure Description

[0028] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0029] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0030] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0031] Please see Figures 1 to 6 A cold air drying apparatus for the production of adamantane hydrochloride, in this embodiment including:

[0032] A drying chamber 1 for cold air drying of adamantane hydrochloride is provided. The side of the drying chamber 1 is hollow, and a cold air blower 2 for cold air drying of adamantane hydrochloride is installed on the outer wall of the drying chamber 1.

[0033] The filter assembly 3 includes an electric push rod 11 and a Z-shaped movable frame 4. The movable frame 4 has two inner cavities, and each inner cavity of the movable frame 4 is connected to a limit frame 5. The side of the limit frame 5 abuts against a filter frame 6. A filter screen 7 is connected to the inner wall of the filter frame 6. Two C-shaped pull plates 8 are provided on the side of the filter screen 7 away from the limit frame 5. The centrifugal side of the two pull plates 8 is connected and fixed to the filter frame 6. Two symmetrically arranged limit plates 9 are connected to the side of the movable frame 4. An L-shaped connecting plate 10 is provided on the upper part of one of the limit plates 9. The end face and inner wall of the connecting plate 10 are respectively connected to the movable end of the movable frame 4 and the electric push rod 11.

[0034] In this embodiment, when it is necessary to dry adamantane hydrochloride, the opening of the drying chamber 1 is oriented towards the adamantane hydrochloride, and the air cooler 2 draws in outside air and inputs it into the drying chamber 1. The air is then output through the opening of the drying chamber 1 to achieve cold air drying of the adamantane hydrochloride. The output end of the air cooler 2 is connected to the drying chamber 1, and the fixed end of the air cooler 2 is connected to the drying chamber 1 by bolts. Since external impurities are easily mixed with adamantane hydrochloride during cold air drying, reducing the production quality of adamantane hydrochloride, the filter assembly 3 is used for filtration. However, the filter screen 7 is easily clogged by impurities, reducing the output air volume of the drying chamber 1, and thus reducing the cold air drying efficiency of the device for adamantane hydrochloride. The device achieves a better drying effect. However, when directly cleaning the debris adhering to the surface of the filter screen 7, the debris will clog the filter screen 7 again under air pressure, reducing the cold air drying effect of the device on amantadine hydrochloride. The electric push rod 11 provides power, and the moving end of the electric push rod 11 moves the connecting plate 10, which in turn moves the moving frame 4. During the transmission process, the two filter screens 7 located in the two inner cavities of the moving frame 4 alternately extend into the drying chamber 1. Pulling the pull plate 8 disassembles the filter frame 6, and the filter screen 7 located outside the drying chamber 1 is disassembled and cleaned to prevent debris from clogging the filter screen 7 again, thus enhancing the cleaning effect on the surface of the filter screen 7 and improving the cold air drying effect of the device on amantadine hydrochloride.

[0035] Specifically, the two inner side walls of the drying oven 1 are slidably connected to the movable frame 4, and the upper part of the fixed end of the electric push rod 11 abuts against two arc-shaped mounting plates 12. The bottom surfaces of the two mounting plates 12 are connected to the drying oven 1 by bolts.

[0036] In this embodiment, the electric push rod 11 is fixed to the top of the drying chamber 1 by two mounting plates 12. Under the power provided by the electric push rod 11, the movable frame 4 can move laterally, so that the two inner cavities of the movable frame 4 alternately extend into the inner cavity of the drying chamber 1. The two limiting plates 9 are used to limit the movement range of the movable frame 4. After one of the inner cavities of the movable frame 4 extends into the interior of the drying chamber 1, one of the inner cavities of the movable frame 4 fits into the inner wall of the drying chamber 1, thereby improving the structural stability of the components of the device.

[0037] Specifically, a collection assembly 13 is provided at the bottom of the drying chamber 1. The collection assembly 13 includes two support plates 15 and two L-shaped support frames 14. The top surfaces of the two support frames 14 are connected to the drying chamber 1, the inner bottom walls of the support frames 14 abut against the support plates 15, and collection boxes 16 are connected to the adjacent sides of the two support plates 15.

[0038] In this embodiment, the inner sidewalls of the two support frames 14 are arranged concentrically, and the adjacent sides of the two support frames 14 are in sliding frictional contact with the collection box 16. When the support plate 15 moves along the inner bottom wall of the support frame 14, the position of the collection box 16 is fixed under the connection provided by the two support plates 15, thereby realizing the installation and fixation of the collection box 16.

[0039] Specifically, a rubber frame 17 is connected to the top surface of the collection box 16. The top surface of the rubber frame 17 is in sliding friction contact with the drying box 1. A through groove adapted to the inner cavity of the rubber frame 17 is opened on the bottom wall of the drying box 1. Abutment plates 18 and limiting bolts 19 are provided on both ends of the collection box 16. Both limiting bolts 19 are threadedly connected to the collection box 16. A through groove is opened on the side of the abutment plate 18 for the threaded part of the limiting bolt 19 to be inserted. The adjacent sides of the two abutment plates 18 abut against the drying box 1. Four support rods 20 are connected to the bottom surface of the drying box 1.

[0040] In this embodiment, the debris inside the drying oven 1 flows into the collection box 16 through the through groove of the drying oven 1. To prevent the debris inside the drying oven 1 from clogging the filter screen 7 again, the two abutment plates 18 are released from the drying oven 1, and the two support plates 15 are moved down along the path of the support frame 14. The collection box 16 is disassembled, the debris collected inside the collection box 16 is cleaned, and the position of the abutment plate 18 is fixed by the limiting bolt 19.

[0041] The air cooler 2 and the electric push rod 11 are both existing technologies. Their working principles, dimensions and models are not related to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0042] Working principle

[0043] The cold air drying device used for the production of adamantane hydrochloride is used by the user to start the cold air blower 2 to introduce cold air into the drying chamber 1. After the cold air is filtered by the filter screen 7, it is discharged through the opening of the drying chamber 1 to dry the adamantane hydrochloride.

[0044] When the filter screen 7 needs cleaning, start the electric push rod 11. During the movement of the moving end of the electric push rod 11, it drives the connecting plate 10 to move, causing the moving frame 4 to move. The two inner cavities of the moving frame 4 alternately extend into the interior of the drying box 1, so that the filter screen 7 that needs to be disassembled and cleaned is moved out of the inner cavity of the drying box 1. Pull the pull plate 8 to disassemble the filter frame 6 and the filter screen 7, and clean the surface of the filter screen 7.

[0045] The debris flowing into the drying oven 1 flows into the collection box 16 through the channel. The two abutment plates 18 are released from the drying oven 1, so that the two support plates 15 are separated from the support frame 14. The collection box 16 is then disassembled and the debris collected in the collection box 16 is disposed of.
