Description

Technical Field

[0001] This utility model relates to the field of optical filter technology, specifically to a centrifugal drying device for optical filter production. Background Technology

[0002] Optical filters are used to select the desired wavelength of radiation. A common characteristic of all filters is that no filter can make the image of a celestial object brighter, because all filters absorb certain wavelengths, thus making the object appear darker.

[0003] In the production process of optical filters, it is necessary to remove impurities and water stains from the surface of the filters. Usually, ultrasonic cleaning equipment is used to clean the impurities on the surface of the filters, and then a centrifugal device is used to dry the filters by throwing off the impurities. However, optical filters are usually round, and the centrifugal device rotates at high speed, causing the stacked filters to come into contact with each other. At the same time, when the filters are centrifuged, the stacked filters collide with each other, causing damage to the filters. Therefore, we propose a centrifugal drying device for optical filter production. Utility Model Content

[0004] To address the shortcomings of existing centrifugal drying devices for filter production, this invention provides a centrifugal drying device for filter production. This device features a design where a spin-drying drum is placed sequentially inside a limiting plate, while a buffer pad limits the positions of the drum's sides. A first positioning plate and a second positioning plate limit the front and rear ends of the drum. This design prevents the spin-drying drum from shifting position during spin-drying, improving the stability of the equipment during centrifugation and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a centrifugal drying device for filter production, including an outer box, a spin-drying drum movably sleeved inside the outer box, a limiting post fixedly connected to the middle of the spin-drying drum, an installation plate fixedly connected to the upper part of the outer box, a positioning sleeve installed on the outside of the installation plate, a top cover installed on the outside of the positioning sleeve, a drying device installed inside the top cover, five sets of sliders movably sleeved inside the limiting post, and a second limiting plate connected to the outside of the sliders.

[0006] Preferably, an air inlet is installed on one side of the upper part of the outer casing, and a drain outlet is installed at the lower end of the outer casing.

[0007] Preferably, a first limiting plate is fixedly connected to the top of the spin dryer, the first limiting plate is clamped between the mounting plate and the positioning sleeve, and a motor is installed at the lower end of the spin dryer.

[0008] Preferably, the drying device includes a gas transmission pipe and a heating air pump, wherein the gas transmission pipe is installed on the upper part of the cover, an air inlet pipe is fixedly connected to the lower part of the gas transmission pipe, and a heating air pump for injecting hot air into the outer casing is installed on the upper part of the gas transmission pipe.

[0009] Preferably, the second limiting plate has a circular cavity in the middle, and a buffer pad is placed inside the cavity. The buffer pad holds a filter inside, and the second limiting plate has an opening inside, which is located in the middle of the filter.

[0010] Preferably, a first positioning plate for defining the filter is mounted on the back of the slider, and a second positioning plate is mounted on the front end of the slider by bolts.

[0011] Preferably, the upper part of the limiting post is threaded with a fixing cover that limits the position of the slider, the second limiting plate is installed vertically inside the spin dryer, and filter holes are equally spaced on the outside of the spin dryer.

[0012] Compared with existing centrifugal drying devices for filter production, this utility model has the following advantages.

[0013] 1. The centrifugal drying device for filter production installs the filter inside the second limiting plate, with a buffer pad limiting both sides of the filter and reducing the contact area between the buffer pad and the filter. At the same time, the front and rear ends of the filter are clamped and fixed by the first and second positioning plates. When the spin-drying drum is started, the positioning of the filter is kept stable during the rotation of the spin-drying drum, while impurities outside the spin-drying drum are centrifugally spun out, thereby improving the overall drying efficiency of the filter.

[0014] 2. The centrifugal drying device for filter production uses a centrifugal drying drum to remove impurities from the filter while a heated air pump continuously injects hot air into the outer chamber through a gas transmission pipe. In other words, the filter is heated and dried simultaneously during the centrifugal process without interfering with each other, thereby improving the overall drying efficiency of the filter.

[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A centrifugal drying device for filter production includes an outer casing 1. A spin-drying drum 4 is movably sleeved inside the outer casing 1. When the spin-drying drum 4 rotates, it drives the equipment to perform centrifugal processing, and the centrifugation drives impurities out. A limiting post 5 is fixedly connected to the middle of the spin-drying drum 4. The limiting post 5 drives the filter 18 to be positioned. An installation plate 6 is fixedly connected to the upper part of the outer casing 1. A positioning sleeve 8 is installed on the outside of the installation plate 6. A top cover 9 is installed on the outside of the positioning sleeve 8. A drying device is installed inside the top cover 9. Five sets of sliders 13 are movably sleeved inside the limiting post 5. A second limiting plate 14 is connected to the outside of the sliders 13. After the filter 18 is installed inside the second limiting plate 14, the filter 18 is limited, and the spin-drying drum 4 drives the second limiting plate 14 to rotate synchronously, so that impurities can be thrown out.

[0023] Please see Figure 1 An air inlet 2 is installed on one side of the upper part of the outer box 1, and a drain outlet 3 is installed at the lower end of the outer box 1. By installing the air inlet 2 on the upper part of the outer box 1, the air inlet 2 drives the air to be injected into the interior of the outer box 1. At the same time, the spin dryer 4 drives the filter to be centrifuged, and the centrifuged impurities are thrown out. The thrown-out impurities are transported to the interior of the outer box 1 and discharged through the drain outlet 3.

[0024] Please see Figure 3A first limiting plate 7 is fixedly connected to the top of the spin-drying drum 4. The first limiting plate 7 is clamped and installed between the mounting plate 6 and the positioning sleeve 8. A motor is installed at the lower end of the spin-drying drum 4. The spin-drying drum 4 drives the first limiting plate 7 to be installed on the upper part of the mounting plate 6. At the same time, a positioning sleeve 8 is installed on the outside of the mounting plate 6. The positioning sleeve 8 limits the position of the first limiting plate 7. After the first limiting plate 7 is clamped between the mounting plate 6 and the positioning sleeve 8, the spin-drying drum 4 remains stable when it rotates.

[0025] Please see Figure 3 The drying device includes a gas transmission pipe 10 and a heating air pump 12. The gas transmission pipe 10 is installed on the upper part of the cover 9, and the lower part of the gas transmission pipe 10 is fixedly connected to the air inlet pipe 11. The upper part of the gas transmission pipe 10 is equipped with a heating air pump 12 for injecting hot air into the outer box 1. With the gas transmission pipe 10 installed on the upper part of the cover 9, the heating air pump 12 is started, and the heating air pump 12 drives the hot air to be transported to the inside of the gas transmission pipe 10. At the same time, it is evenly transported to the inside of the outer box 1 through the air inlet pipe 11. The hot air is delivered to the inside of the outer box 1, that is, the hot air dries the filter 18 placed inside the spin dryer 4, ensuring the overall drying efficiency of the equipment.

[0026] Please see Figure 5 The second limiting plate 14 has a circular cavity in the middle, and a buffer pad 17 is placed inside the cavity. The filter 18 is held inside the buffer pad 17. The second limiting plate 14 has an opening 16 in the middle of the filter 18. The filter 18 is placed inside the cavity in the middle of the second limiting plate 14, which provides stability for the filter 18. At the same time, when the spin dryer 4 rotates for centrifugal treatment, the liquid adhering to the outside of the filter 18 can be thrown out through the opening 16, ensuring that the filter 18 will not interfere with the throwing out of the liquid under the limited state. At the same time, the buffer pad 17 is placed outside the filter 18, that is, the buffer pad 17 limits the installation position of the filter 18.

[0027] Please see Figure 5 A first positioning plate 19 is installed on the back of the slider 13 to limit the filter 18. A second positioning plate 20 is installed at the front end of the slider 13 by bolts. The filter 18 and the first positioning plate 19 are installed at both ends of the slider 13 respectively. The filter 18 limits the rear end of the filter 18, and the second positioning plate 20 limits the front end of the filter 18 to ensure that the filter 18 remains stable when clamped inside the second limiting plate 14.

[0028] Please see Figure 4A fixing cover 15 is threaded onto the upper part of the limiting post 5 to limit the position of the slider 13. The second limiting plate 14 is installed vertically inside the spin dryer 4. At the same time, filter holes are opened at equal intervals on the outside of the spin dryer 4. After the second limiting plate 14 is vertically installed on the outside of the limiting post 5 by the slider 13, the fixing cover 15 is installed on the upper part of the limiting post 5. The fixing cover 15 limits the position of the slider 13. At the same time, filter holes are opened on the outside of the spin dryer 4. When the spin dryer 4 rotates, the spin dryer 4 throws out the liquid adhering to the outside of the filter 18, ensuring that the filter 18 is centrifugally dried as a whole.

[0029] Working principle: When in use, open the top cover 9 and place the filter 18 into the circular cavity inside the second limiting plate 14. At the same time, the buffer pad 17 limits the position of the filter 18. The first positioning plate 19 and the second positioning plate 20 are installed at the front and rear ends of the second limiting plate 14 to ensure the stability of the filter 18 during centrifugation. At the same time, close the top cover 9 and heat the air pump 12. The heating air pump 12 drives the hot air through the gas transmission pipe 10 and the air inlet pipe 11 to deliver it to the inside of the outer box 1 to dry the filter 18. At the same time, start the motor installed at the bottom of the spin dryer 4. The motor drives the spin dryer 4 to rotate. When the spin dryer 4 rotates, it drives the liquid adhering to the outside of the filter 18 to be thrown out, thereby achieving centrifugal filtration and centrifugal drying of the filter 18.
