Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a diazaspiro-octane-carboxylic acid tert-butyl ester filtration device. Background Technology

[0002] Diazaspiro-octane-carboxylic acid tert-butyl ester is a chemical substance that is currently a very popular research area and is increasingly favored by new drug development companies. Its production process requires a feeding device. However, existing devices cannot completely filter the raw materials during feeding; impurities fall into the equipment, cannot be fully mixed, and will settle at the bottom, reducing the quality of 2-tert-butoxycarbonyl-oxa-diazaspirononane. Furthermore, existing devices are usually placed directly above the feed hopper, which is inconvenient for fixed installation and compromises the stability of the device, making it prone to tipping over in the event of a collision.

[0003] The existing patent (publication number: CN216571877U) discloses a feeding device for the production of 2-tert-butoxycarbonyl-oxa-diazaspironnonane. The device utilizes a first and second filter plate to facilitate dual filtration of the raw material, resulting in a purer product. Furthermore, the coordinated design of the drive assembly, limiting rod, and return spring ensures that the frame continuously performs horizontal reciprocating motion during operation, thereby improving the filtration efficiency. However, in implementing this solution, the following problems were found in the existing technology, which have not been adequately resolved:

[0004] During use, the device filters and screens impurities of various sizes through a first and second double filter screen. However, all the screened impurities accumulate inside the main body of the device, making cleaning difficult and preventing continuous operation. Furthermore, the device is fixed to the feed position by a threaded structure, which makes it easy for impurities to fall into the middle gap and affect the feed. Utility Model Content

[0005] To address the aforementioned problem of difficult cleaning of filtered impurities and their tendency to fall into gaps at the connection points, this invention provides a diazaspiro-octane-tert-butyl carboxylate filtration device, employing the following technical solution:

[0006] A diazaspiro-octane-tert-butyl carboxylate filtration device includes a main body and an inlet at the upper end of the main body. An electric push rod is connected to the upper part of the main body, a support plate is connected to the upper part of the electric push rod, a drive rod is arranged below the support plate, a drive mechanism is connected to the upper part of the drive rod, and a stirring rod is connected to the lower part of the drive rod. A first filter screen is also connected inside the main body, a first spring is connected below the first filter screen, a first adsorption magnet is connected inside the first filter screen, a second adsorption magnet is connected to the inner side of the first adsorption magnet, and a second filter screen is connected to the inner side of the second adsorption magnet.

[0007] A telescopic belt is connected to the lower part of the main body of the device. Extension blocks are connected to both sides of the telescopic belt. A fixing block is connected to the lower part of the extension blocks. A second spring is connected to the outer side of the fixing block. A clamping block is connected to the other side of the second spring. A sliding block is connected to the center of the clamping block.

[0008] The above technical solution facilitates filtration through the cooperation of the first and second filter screens. The conical structure allows impurities to accumulate in the center. The filter screen is then lifted by the drive rod and electric push rod for easy cleaning of impurities. At the same time, the telescopic belt and clamping block work together to clamp the telescopic belt inside the feed inlet of the equipment, preventing material from accumulating at the connection point.

[0009] Optionally, in the above-mentioned diazaspiro-octane-carboxylic acid tert-butyl ester filtration device, electric push rods are symmetrically distributed on both sides above the main body of the device. The electric push rods and the support plate form an integrated lifting structure, and the support plate and the drive rod form an integrated lifting structure.

[0010] The above technical solution facilitates the lifting of the drive rod and support plate by using an electric push rod, making it easier to clean up impurities.

[0011] Optionally, in the above-mentioned diazaspiro-octane-tert-butyl carboxylate filtration device, the drive rod is located inside the feed inlet, and stirring rods are symmetrically distributed on both sides of the drive rod. The drive rod is connected to the second filter screen by a rotatable connection.

[0012] The above technical solution facilitates the mixing of the material above the second filter screen by the cooperation of the drive rod and the stirring rod, thus ensuring the filtration effect.

[0013] Optionally, in the above-mentioned diazaspiro-octane-tert-butyl carboxylate filtration device, the first spring is evenly distributed at equal angles below the first filter screen, the first filter screen is connected to the main body of the device by a sliding connection, and the first filter screen and the first adsorption magnet are installed as an integral unit.

[0014] The above technical solution facilitates the interaction between the first filter screen and the first spring, allowing the first filter screen to vibrate and ensuring the filtration effect.

[0015] Optionally, in the above-mentioned diazaspiro-octane-tert-butyl carboxylate filtration device, the first adsorption magnet and the second adsorption magnet have a mutual adsorption structure, the first adsorption magnet has an "L" shaped structure, and the second adsorption magnet and the second filter screen are integrated into one unit.

[0016] The above technical solution facilitates the use of the first and second adsorption magnets to enable the second filter screen to be quickly connected to and disconnected from the first filter screen, making it easier to detach the second filter screen.

[0017] Optionally, in the above-mentioned diazaspiro-octane-tert-butyl carboxylate filtration device, the second filter screen is connected to the stirring rod by a sliding connection, and a second filter screen is also provided below the second filter screen, and the diameter of the lower second filter screen and the stirring rod is smaller than the diameter of the upper second filter screen.

[0018] The above technical solution facilitates the removal and cleaning of impurities by setting two second filters of different sizes and a stirring rod.

[0019] Optionally, in the above-mentioned diazaspiro-octane-tert-butyl carboxylate filtration device, extension blocks are evenly distributed at equal angles around the perimeter of the telescopic belt, the extension blocks are connected to the fixed blocks by heat fusion, and the extension blocks are connected to the clamping blocks by sliding connection.

[0020] The above technical solution facilitates the use of a telescopic belt and an extension block to fix the device at the feed inlet.

[0021] Optionally, in the above-mentioned diazaspiro-octane-tert-butyl carboxylate filtration device, the connection between the fixed block and the sliding block is a heat-fusion connection, the connection between the sliding block and the clamping block is a sliding connection, and the clamping block forms a spring damping structure with the fixed block through a second spring.

[0022] The above technical solution facilitates the limiting of the clamping block by the sliding block, thus preventing the feed inlet of the device from affecting the connection stability of the second spring.

[0023] In summary, this utility model has at least one of the following beneficial effects:

[0024] By installing a first filter and a second filter inside the main body of the device, after filtering the material, impurities accumulate in the center. After filtration, the electric push rod drives the second filter to rise, thereby quickly cleaning the impurities. The first filter and the second filter are connected by an adsorption magnet to ensure quick disassembly and automatic alignment, which facilitates the cleaning of impurities.

[0025] By installing a telescopic belt at the bottom of the main body of the device, the telescopic belt extends into the inside of the feed inlet of the device, and the rear fixing block is attached to the inner wall of the feed inlet. The clamping block is driven by the second spring to approach the outer wall of the feed inlet, thus completing the limiting and fixing of the telescopic belt. This can be adapted to devices of different sizes and at the same time prevent materials from falling at the connection point. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0033] An embodiment of this utility model provides a diazaspiro-octane-tert-butyl carboxylate filtration device, comprising a device body 1, and an inlet 5 at the upper end of the device body 1. An electric push rod 6 is connected to the upper part of the device body 1, a support plate 3 is connected to the upper part of the electric push rod 6, and a drive rod 2 is provided below the support plate 3. The electric push rod 6 drives the support plate 3 to rise and fall, thereby causing the drive rod 2 to rise and fall. A drive mechanism 4 is connected to the upper part of the drive rod 2, and a stirring rod 7 is connected to the lower part of the drive rod 2. The stirring rod 7 stirs the material to ensure the filtration effect. A first filter screen 9 is also connected inside the device body 1. A first spring 8 is connected below the first filter screen 9. A first adsorption magnet 10 is connected inside the first filter screen 9. The first adsorption magnet 10 cooperates with a second adsorption magnet 11 to complete the disassembly and connection of the first filter screen 9 and the second filter screen 12. The second adsorption magnet 11 is connected to the inner side of the first adsorption magnet 10, and the second filter screen 12 is connected to the inner side of the second adsorption magnet 11.

[0034] A telescopic belt 13 is connected to the lower part of the main body 1 of the device. Extension blocks 14 are connected to both sides of the telescopic belt 13. The extension blocks 14 cooperate with the fixing blocks 15 to initially limit the telescopic belt 13. The fixing blocks 15 are connected to the lower part of the extension blocks 14. A second spring 16 is connected to the outer side of the fixing blocks 15. The second spring 16 cooperates with the clamping block 18 to complete the fixing work. The clamping block 18 is connected to the other side of the second spring 16. A sliding block 17 is connected to the center of the clamping block 18.

[0035] Working principle: When in use, first, move the main body 1 of the device to the device to be used, insert the telescopic belt 13 into the inlet of the device, and then move the extension block 14 so that the fixing block 15 fits against the inner edge of the inlet. At this time, the clamping block 18 is on the outside of the inlet, the sliding block 17 is on top, and the second spring 16 pulls the clamping block 18 to fit tightly against the outside, ensuring that it is firmly fixed.

[0036] As described above, after the fixing work is completed, the material is placed into the interior of the main body 1 through the feed port 5 on the top of the main body 1. At this time, the material falls above the first filter screen 9 and enters above the second filter screen 12 along the first filter screen 9. Then, the switch of the electric push rod 6 and the drive mechanism 4 is turned on, so that the drive rod 2 starts to drive the stirring rod 7 to rotate, ensuring the filtration effect. At the same time, the electric push rod 6 drives the drive rod 2, the second filter screen 12 and the first filter screen 9 to move through the support plate 3. Then, the vibration of the first spring 8 causes the filter screen to vibrate, further improving the filtration effect. After the filtration work is completed, the electric push rod 6 drives the support plate 3, the drive rod 2 and the second filter screen 12 to move out of the main body 1, and then the impurities can be cleaned.

[0037] It should be noted that electric push rods 6 are symmetrically distributed on both sides of the upper part of the main body 1 of the device. The electric push rods 6 and the support plate 3 form an integrated lifting structure, and the support plate 3 and the drive rod 2 form an integrated lifting structure. The electric push rods 6 drive the drive rod 2 and the support plate 3 to rise, which facilitates the cleaning of impurities.

[0038] It should be noted that the drive rod 2 is located inside the feed inlet 5, and the stirring rods 7 are symmetrically distributed on both sides of the drive rod 2. The drive rod 2 is connected to the second filter screen 12 by rotation. The material above the second filter screen 12 is stirred by the cooperation of the drive rod 2 and the stirring rods 7 to ensure the filtration effect.

[0039] It should be further explained that the first springs 8 are evenly distributed at equal angles below the first filter screen 9. The first filter screen 9 is connected to the main body 1 of the device by a sliding connection. The first filter screen 9 and the first adsorption magnet 10 are installed as an integral unit. Through the cooperation between the first filter screen 9 and the first springs 8, the first filter screen 9 can vibrate to ensure the filtration effect.

[0040] It should be further explained that the first adsorption magnet 10 and the second adsorption magnet 11 are mutually adsorbed. The first adsorption magnet 10 has an "L" shape, and the second adsorption magnet 11 and the second filter screen 12 are integrated. By using the cooperation of the first adsorption magnet 10 and the second adsorption magnet 11, the second filter screen 12 can be quickly connected and disconnected from the first filter screen 9, which facilitates the detachment of the second filter screen 12.

[0041] It should be noted that the second filter screen 12 is connected to the stirring rod 7 by a sliding connection. A second filter screen 12 is also provided below the second filter screen 12, and the diameter of the lower second filter screen 12 and the stirring rod 7 is smaller than the diameter of the upper second filter screen 12. By setting two second filter screens 12 and stirring rod 7 of different sizes, it is convenient for the lower second filter screen 12 to detach and clean impurities.

[0042] It should be noted that extension blocks 14 are evenly distributed at equal angles around the telescopic belt 13. The extension blocks 14 are connected to the fixed block 15 by heat fusion, and the extension blocks 14 are connected to the clamping block 18 by sliding connection. The telescopic belt 13 and the extension blocks 14 cooperate to fix it at the feed port of the device.

[0043] It should be noted that the connection between the fixed block 15 and the sliding block 17 is a heat fusion connection, and the connection between the sliding block 17 and the clamping block 18 is a sliding connection. The clamping block 18 forms a spring damping structure with the fixed block 15 through the second spring 16. The sliding block 17 limits the clamping block 18 to avoid the feed port of the device affecting the connection stability of the second spring 16.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
