[0017] 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.
[0018] Example 1:
[0019] like Figures 1-5As shown, this utility model provides a vitamin C fermentation broth filtration device, including a frame 1. A filter barrel 3 is fixedly mounted on the frame 1 via a fixing base 2. The filter barrel 3 is tilted, and a spiral scraper 4 is movably mounted on the filter barrel 3. A filter screen 5 is fixedly mounted on the wall of the filter barrel 3. A motor base 6 is fixedly mounted on the frame 1, and a drive motor 7 is fixedly mounted on the motor base 6. The drive motor 7 is drivenly connected to the spiral scraper 4. A collection tray 8 is fixedly mounted on the frame 1 below the filter screen 5, and a residue tray 9 is fixedly mounted on the frame 1 at the opening of the filter barrel 3. The spiral scraper 4 has raised ribs 10, and soft rubber 11 is fixedly mounted on the raised ribs 10. The soft rubber 11 is made of silicone. The tilt angle of the filter barrel 3 is 30°. A rubber ring 12 is sealed between the filter barrel 3 and the filter screen 5.
[0020] Through the above technical solution, this utility model has a filter barrel 3 inclinedly arranged on the frame 1, a spiral scraper 4 movably installed on the filter barrel 3, the spiral scraper 4 being driven to rotate by the drive motor 7, a filter screen 5 fixedly installed on the barrel wall of the filter barrel 3, a collection tray 8 fixedly installed on the frame 1 below the filter screen 5, and a residue tray 9 fixedly installed on the frame 1 at the opening of the filter barrel 3. When the equipment is running, vitamin C fermentation liquid is injected into the filter barrel 3, filtered through the filter screen 5, and dripped into the collection tray 8. At the same time, the drive motor 7 drives the spiral scraper 4 to rotate, the spiral scraper 4 scrapes away the residue on the surface of the filter screen 5, and scrapes the residue into the residue tray 9 located at the opening of the filter barrel 3, preventing the residue from accumulating on the filter screen 5 and improving the filtration efficiency.
[0021] Example 2:
[0022] like Figures 1-5 As shown, the frame 1 of this invention serves as the supporting structure for the entire device and is made of metal, possessing sufficient strength and stability. A mounting base 2 is provided on the frame 1 for mounting the filter barrel 3. The filter barrel 3 is mounted on the frame 1 via the mounting base 2, and is positioned at an angle. This angle allows a filter screen 5 to be installed on the downward-facing side wall of the filter barrel 3, utilizing gravity to promote liquid flow and solid residue separation. The filter barrel 3 is made of corrosion-resistant material, capable of withstanding the corrosive environment of the vitamin C fermentation broth.
[0023] A spiral scraper 4 is movably installed inside the filter tank 3. The spiral scraper 4 is made of metal and has a corrosion-resistant surface. Its design allows it to rotate closely against the inner wall of the filter tank 3, effectively removing residue adhering to the filter screen 5. The filter screen 5 is fixedly installed on the wall of the filter tank 3. The filter screen 5 is made of stainless steel, which is corrosion-resistant. The mesh size is selected according to the specific conditions of the vitamin C fermentation broth to ensure effective separation of liquid and solid components.
[0024] A motor mount 6 is fixedly installed on the frame 1, and the motor mount 6 is used to mount the drive motor 7. The drive motor 7 is fixedly mounted on the motor mount 6 and connected to the spiral scraper 4 through a transmission mechanism, providing rotational power to the spiral scraper 4. The power of the drive motor 7 is selected according to actual needs to ensure that it can overcome the resistance when the spiral scraper 4 rotates.
[0025] A collection tray 8 is fixedly installed on the frame 1 below the filter screen 5. The collection tray 8, made of corrosion-resistant material, is used to collect the liquid passing through the filter screen 5 and has a certain capacity. The shape of the collection tray 8 is designed to facilitate liquid collection and discharge. A residue tray 9 is fixedly installed on the frame 1 at the opening of the filter tank 3. The residue tray 9 is used to collect solid residue scraped off by the spiral scraper 4 and is also made of corrosion-resistant material. The design of the residue tray 9 takes into account factors that facilitate residue collection and cleaning.
[0026] During operation, the vitamin C fermentation broth is injected into the inclined filter tank 3. Under gravity, the liquid passes through the filter screen 5, and the filtered liquid drips into the collection tray 8 below. Simultaneously, the drive motor 7 rotates the spiral scraper 4, which continuously scrapes away residue adhering to the surface of the filter screen 5 and transports this residue to the residue tray 9 at the opening of the filter tank 3. This design achieves continuous filtration of the liquid and automatic removal of residue, improving filtration efficiency.
[0027] Example 3:
[0028] like Figures 1-5As shown, the spiral scraper 4 of this utility model has raised ribs 10, and soft rubber 11 is fixedly installed on the raised ribs 10. The spiral scraper 4 is made of metal material and has a spiral shape, which can rotate inside the filter barrel 3. The surface of the spiral scraper 4 is provided with raised ribs 10. Soft rubber 11 is fixedly installed on the raised ribs 10. Soft rubber 11 is made of flexible material and has good elasticity and wear resistance. The function of soft rubber 11 is to make the spiral scraper 4 in soft contact with the filter screen 5. When the spiral scraper 4 rotates, soft rubber 11 can gently adhere to the surface of the filter screen 5, effectively removing the residue attached to the filter screen 5. This soft contact greatly reduces the wear between the spiral scraper 4 and the filter screen 5 and extends the service life of the filter screen 5. At the same time, the elasticity of soft rubber 11 ensures good contact even if there are slight unevennesses on the surface of the filter screen 5, ensuring that the scraper can thoroughly clean the surface of the filter screen 5. During the filtration process, when the vitamin C fermentation liquid passes through the filter screen 5, some solid residue will adhere to the surface of the filter screen 5. As the spiral scraper 4 rotates, the soft rubber 11 on the ribs 10 scrapes across the surface of the filter screen 5, removing the residue. The removed residue is transported along the spiral trajectory of the spiral scraper 4 to the opening of the filter barrel 3, and finally falls into the residue tray 9. This design not only improves filtration efficiency but also reduces the frequency of equipment maintenance. Traditional filtration devices often require frequent shutdowns for cleaning due to residue accumulation, while this spiral scraper 4 design with soft rubber 11 and ribs 10 allows the filtration process to continue continuously, greatly improving production efficiency. At the same time, the use of soft rubber 11 reduces direct contact between metal parts, lowering the noise level during equipment operation.
[0029] Example 4:
[0030] like Figures 1-5As shown, the soft adhesive 11 of this invention is made of silicone. Silicone is a high-performance organic polymer material with many properties suitable for this filtration device. Silicone has excellent chemical stability and can maintain good performance in the acidic environment of vitamin C fermentation broth. Vitamin C fermentation broth is usually acidic with a low pH value, and ordinary materials are prone to corrosion or performance degradation in this environment. However, silicone can withstand acidic environments for a long time and will not undergo chemical reactions or dissolve upon contact with the fermentation broth, ensuring the stability of the soft adhesive 11 during long-term use. Silicone also has excellent temperature resistance. During the filtration of vitamin C fermentation broth, the liquid temperature may fluctuate. Silicone can maintain good elasticity and mechanical properties over a wide temperature range and will not harden or soften due to temperature changes, ensuring that the spiral scraper 4 maintains good cleaning performance under different temperature conditions. Elasticity is another important characteristic of silicone. The elasticity of silicone allows the soft adhesive 11 on the spiral scraper 4 to adhere tightly to the surface of the filter screen 5, maintaining good contact even if there are minor unevenness or deformation on the surface of the filter screen 5. This elasticity ensures that the spiral scraper 4 can thoroughly and evenly clean the surface of the filter screen 5, leaving no area untouched. During long-term rotating cleaning, the silicone rubber 11 will continuously rub against the surface of the filter screen 5. The excellent abrasion resistance of the silicone rubber ensures that the silicone rubber 11 will not wear out too quickly due to long-term use, extending its service life and reducing the frequency of maintenance and replacement.
[0031] Example 5:
[0032] like Figures 1-5 As shown, the filter bucket 3 of this invention is mounted on the frame 1 via a fixed base 2 and is set at a 30° tilt angle. The tilted design of the filter bucket 3 makes full use of gravity, allowing the fermentation broth to flow better towards the filter screen 5, thus improving filtration efficiency. A spiral scraper 4 is movably installed inside the filter bucket 3, and the filter screen 5 is fixedly installed on the bucket wall. The filter screen 5 is located on the downward-facing side wall of the filter bucket 3, and this arrangement further optimizes the filtration process. When the vitamin C fermentation broth is poured into the tilted filter bucket 3, the liquid naturally flows towards the filter screen 5, while the solid residue moves towards the bucket opening under the action of gravity and the spiral scraper 4. The drive system includes a motor base 6 fixed on the frame 1 and a drive motor 7 mounted on the motor base 6. The drive motor 7 is connected to the spiral scraper 4 and is used to drive the spiral scraper 4 to rotate. The continuous rotation of the spiral scraper 4 not only scrapes off the residue adhering to the surface of the filter screen 5, but also promotes a more uniform distribution of liquid on the surface of the filter screen 5, thus improving filtration efficiency.
[0033] Example 6:
[0034] like Figures 1-5As shown, a rubber ring 12 is installed between the filter barrel 3 and the filter screen 5 of this utility model to improve the sealing performance of the connection between the filter barrel 3 and the filter screen 5. The filter barrel 3 adopts a cylindrical structure, and its downward side wall has an installation hole that matches the filter screen 5. The filter screen 5 has a planar structure, and its outer edge is slightly larger than the size of the installation hole. During installation, the rubber ring 12 is first placed on the outer edge of the filter screen 5, and then the filter screen 5 together with the rubber ring 12 is pressed into the installation hole. Under pressure, the rubber ring 12 undergoes elastic deformation, tightly fitting the inner wall of the filter barrel 3 and the outer edge of the filter screen 5, forming an effective sealing barrier. This design ensures that during the filtration process, liquid can only pass through the filter screen 5 and will not leak from the connection between the filter screen 5 and the filter barrel 3.
