Description

Technical Field

[0001] This utility model relates to the technical field of vacuum drying of optical filters, specifically a vacuum drying oven for optical filters. Background Technology

[0002] A filter is an optical device used to selectively filter spectral components, allowing light of a specific wavelength range to pass through while blocking or reflecting light of other wavelengths. In the production process of filters, they need to be dried. This drying process can be accomplished with the help of a vacuum drying oven. The vacuum state of the vacuum drying oven lowers the boiling point of water and speeds up the drying process.

[0003] As disclosed in CN212870476U, a constant temperature drying oven for optical filters belongs to the field of optical filter drying technology. It includes a box body, a display and controller mounted on the surface of the box body, partitions and a drying layer inside the box body. An air inlet is connected to the bottom of the box body, which is connected to a ventilation duct inside the box body. A heating layer is located above the ventilation duct. Above the heating layer are, in sequence, a drying layer B, a partition B, a drying layer A, and another partition A. Both partitions A and B are inclined. A receiving tray is located below the lowest point of partitions A and B, and the receiving tray is fixed to the inside of the box body. An air outlet is located at the top of the box body. A temperature sensor is located inside the box body, and the temperature sensor and heating layer are electrically connected to the controller. This utility model drying oven has high drying efficiency. The upper and lower partitions ensure that the drying of the optical filters on the upper and lower partitions does not affect each other. The inclined partitions allow water on the optical filters to drain along the drainage channel to the receiving tray for drying.

[0004] However, existing technologies have problems such as uneven and insufficient contact between the filter and the hot air, poor uniformity of filter drying, and inconvenience in taking the filter out of the drying chamber. For example, the comparative patents listed above have this problem.

[0005] To address these issues, we propose a filter vacuum drying oven. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum drying oven for optical filters, which solves the problems mentioned in the background art, such as insufficient and uneven contact between the optical filters and hot air, poor uniformity of drying of the optical filters, and inconvenience in taking the optical filters out of the drying oven.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter vacuum drying oven, comprising a vacuum drying oven body, a cover plate, and multiple drying trays;

[0008] Also includes:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 .

[0032] To address the problems in existing technologies, such as insufficient and uneven contact between the filter and hot air, poor uniformity in filter drying, and inconvenience in handling the filters in the drying chamber, this solution provides a filter vacuum drying chamber comprising a vacuum drying chamber body 1, a cover plate 3, and multiple drying trays 15. A rotating assembly is located at the bottom of the vacuum drying chamber body 1 and includes a geared motor 7 for driving, a drive platform 8 fixed to the output end of the geared motor 7, a connecting plate 11 located on the upper end of the drive platform 8, and a fixing column 13 fixed to the upper end of the connecting plate 11. The rotating assembly drives the drying trays 15 to rotate slowly within the vacuum drying chamber body 1. A water receiving tray 16 is fixedly connected to the lower end of the drying tray 15, and drain outlets 17 are provided at both ends of the water receiving tray 16.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, firstly, the filters to be dried are evenly arranged in the drying tray 15. The lower end of the drying tray 15 is fixedly connected to the water receiving tray 16. The fixing post 13 is inserted into the middle of the drying tray 15 and the water receiving tray 16. Then, the fixing bolt 18 is rotated to limit the distance between the fixing post 13 and the drying tray 15. Then, the above operation is repeated to place the drying tray 15 on the fixing post 13 at equal intervals. Then, holding the fixing post 13, the fixing post 13 and the drying tray 15 are placed inside the vacuum drying chamber body 1. The lower end of the fixing post 13 is fixedly connected to the connecting plate 11, and the lower end of the connecting plate 11 is provided with connecting holes 12 at equal angles. The aforementioned protrusion 10 at the far end of the drive table 8 is engaged in the connecting hole 12. Since the number of connecting holes 12 is greater than the number of protrusions 10, the protrusions 10 can be engaged in the connecting holes 12 at any position at the lower end of the protrusions 10.

[0034] After the cards are combined, as follows Figure 1 , Figure 3 and Figure 5 As shown, the handle 4 at the upper end of the cover plate 3 is used to engage the cover plate 3 with the upper end of the vacuum drying oven body 1. A sealing gasket is also provided between the cover plate 3 and the vacuum drying oven body 1 to maintain a tight seal at the connection. Connecting plates 5 are fixedly connected to both ends of the cover plate 3. The cover plate 3 drives the connecting plates 5 to engage with the fixing rod 2 on the outer side of the upper end of the vacuum drying oven body 1 through a slotted connection. Then, the connecting cap 6, which is threaded onto the outer surface of the fixing rod 2, is rotated, causing the connecting cap 6 to engage with the lower end of the connecting plate 5, thus facilitating the limiting of the connection between the connecting plate 5 and the fixing rod 2. The cover plate 3 is fixed to the upper end of the vacuum drying oven body 1, and the middle of the lower end of the cover plate 3 is rotatably connected to the movable sleeve 14. The cover plate 3 drives the movable sleeve 14 to engage with the upper end of the fixed column 13. The vacuum pump built into the vacuum drying oven body 1 draws the interior of the vacuum drying oven body 1 into a vacuum state. The filter on the drying tray 15 is dried by the vacuum drying oven body 1. The vacuum drying oven body 1 is completely consistent with the existing vacuum drying oven, which is a conventional and mature technology that is well known to those in the art. The drying process of the filter will not be described in detail.

[0035] During the drying process, such as Figure 2 and Figure 4As shown, the geared motor 7 installed at the bottom of the vacuum drying oven body 1 can be activated. The geared motor 7 drives the drive platform 8 to rotate slowly at the bottom of the vacuum drying oven body 1. The geared motor 7 drives the ball bearings 9 to roll at the bottom of the vacuum drying oven body 1, which can support the drive platform 8 and improve the stability during rotation. The drive platform 8, together with the protrusion 10 and the connecting plate 11, causes the fixing column 13 to drive the drying tray 15 to rotate slowly in the vacuum drying oven body 1, thereby achieving a more uniform drying effect for the filters in the drying tray 15. In addition, the bottom of the drying tray 15 has a mesh structure. Water droplets dripping downwards during the drying process can be collected by the water receiving tray 16 and discharged to the outside through the drain outlet 17, preventing water droplets from dripping onto the filters on the lower drying tray 15 and causing contamination. After drying is completed, the drying tray 15 can be disassembled by reversing the above operation, which facilitates the removal and placement of the filters.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
