Description

Technical Field

[0001] This utility model relates to the field of filtration devices, and more particularly to a filtration device for high-temperature viscous materials. Background Technology

[0002] Ceramic filter membranes, also known as inorganic ceramic membranes, are precision ceramic filter materials with a porous structure, made by sintering inorganic materials such as alumina, titanium dioxide, and zirconium oxide at a high temperature of 1700℃. Their filtration precision covers microfiltration, ultrafiltration, and nanofiltration. They typically have a three-layer structure, including a porous support layer, a transition layer, and a separation layer. The support layer is generally several millimeters thick, with a pore size ranging from approximately 1 to 10 μm; the intermediate transition layer is generally 10 to 100 μm thick, with a pore size typically ranging from 50 to 100 nm; and the separation layer is very thin, approximately 1 to 10 μm thick, with a pore size usually below 100 nm. Inorganic ceramic membranes have the following characteristics:

[0003] It has good chemical stability: it is resistant to acids and alkalis, high temperatures, and even organic solvents, and can operate stably in extreme environments.

[0004] High mechanical strength: Compared with traditional materials, it can withstand greater pressure, is not easily damaged, and ensures long-term stable operation under high pressure differential working conditions.

[0005] Strong antimicrobial ability: It has a strong resistance to microorganisms and is suitable for occasions that require hygiene protection, such as food and beverage, biopharmaceutical and other fields.

[0006] Narrow pore size distribution: The pore size distribution is uniform, the separation efficiency is high, and more precise filtration can be achieved, effectively removing various impurities and improving the quality of filtration products.

[0007] High temperature resistance: It can maintain stable performance in high temperature environments and can withstand temperatures up to 400℃ or even higher, making it suitable for industrial processes that require high-temperature treatment.

[0008] Easy to clean and regenerate: It can be regenerated through chemical cleaning and physical backwashing, has good anti-fouling ability, and can extend its service life.

[0009] When filtering high-temperature viscous materials, tubular ceramic filter membranes are typically used. The high-temperature viscous material is injected into the cavity of the ceramic filter membrane, where impurities are trapped. The filtered high-temperature viscous material overflows outside the ceramic filter membrane. Currently, there are the following problems when using ceramic filter membranes to filter high-temperature viscous materials: First, using a single ceramic filter membrane results in low filtration efficiency. Second, under the influence of gravity, the ceramic filter membrane usually only has its lower part in contact with the high-temperature viscous material, leading to low utilization of the ceramic filter membrane.

[0025] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-3As shown, it includes a first material conveying pipe 12, a drive pipe 13 is sleeved on the right end of the first material conveying pipe 12, the outer wall of the first material conveying pipe 12 is in contact with the inner wall of the drive pipe 13, a second material conveying pipe 3 is sleeved on the right end of the drive pipe 13, there is a space between the drive pipe 13 and the second material conveying pipe 3, a first sealing cap 7 is fixedly installed on the right end of the second material conveying pipe 3, and a plurality of third material conveying pipes 5 are arranged in a circular array on the right end of the second material conveying pipe 3. One end of the third material conveying pipe 5 is fixedly connected to and communicates with the second material conveying pipe 3, and the other end of the third material conveying pipe 5 is fixedly connected to and communicates with the left end of the fourth material conveying pipe 6. The right end of the fourth material conveying pipe 6 is fixedly connected to the left end of the tubular ceramic filter membrane 8, and a second sealing cap 9 is fixedly installed on the right end of the ceramic filter membrane 8.

[0029] The first material conveying pipe 12 is installed through the first support plate 1 and is fixedly connected to the first support plate 1. The bottom surface of the first support plate 1 is fixedly connected to the ground. The second material conveying pipe 3 is fitted with a bearing 11. The inner ring of the bearing 11 is fixedly connected to the second material conveying pipe 3. The outer ring of the bearing 11 is installed through the second support plate 4 and is fixedly connected to the second support plate 4. The second support plate 4 is fixedly connected to the ground.

[0030] A drive motor 2 is fixedly mounted on the first support plate 1. The power output end 16 of the drive motor 2 is fixedly connected to the first gear 15. The first gear 15 meshes with the second gear 14, which is fixedly sleeved on the drive tube 13. An auger blade 18 is spirally wound on the right end of the drive tube 13. The drive tube 13 is fixedly connected to the auger blade 18, which is located inside the second material conveying tube 3. A sealing strip 17 is fixedly mounted on the edge of the auger blade 18, and the sealing strip 17 is in contact with the inner wall of the second material conveying tube 3.

[0031] In use, the high-temperature viscous material is conveyed to the drive pipe 13 through the first material conveying pipe 12. The high-temperature viscous material enters the second material conveying pipe 3 through the right end of the drive pipe 13. Since the sealing strip 17 is fixed on the edge of the auger blade 18, the left end of the second material conveying pipe 3 is blocked. The high-temperature viscous material can only enter the third material conveying pipe 5 through the right end of the second material conveying pipe 3, and then enter the ceramic filter membrane 8 through the fourth material conveying pipe 6. The high-temperature viscous material seeps out to the outside of the ceramic filter membrane 8, and the impurities inside the high-temperature viscous material are trapped inside the ceramic filter membrane 8.

[0032] While conveying the high-temperature viscous material to the drive pipe 13 through the first material conveying pipe 12, the drive motor 2 is started. The drive motor 2 drives the drive pipe 13 to rotate through the first gear 15 and the second gear 14. The drive pipe 13 drives the auger blade 18 and the sealing strip 17 to rotate synchronously. Under the action of friction, the sealing strip 17 drives the second material conveying pipe 3 to rotate slowly. The second material conveying pipe 3 drives the third material conveying pipe 5, the fourth material conveying pipe 6 and the ceramic filter membrane 8 to rotate synchronously, so that the high-temperature viscous material in the ceramic filter membrane 8 can be in uniform contact with all parts of the ceramic filter membrane 8.

[0033] Example 2

[0034] like Figure 1-3 As shown, while all other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that a first storage box 19 is provided below the drive tube 13, and a second storage box 10 is provided below the ceramic filter membrane 8.

[0035] If material leaks out at the connection between the first material conveying pipe 12 and the drive pipe 13, or at the connection between the drive pipe 13 and the second material conveying pipe 3, it will drip into the first storage box 19 and be collected.

[0036] After the high-temperature viscous material seeps out from the ceramic filter membrane 8, it drips into the second storage box 10 and is collected.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
