Description

Technical Field

[0001] This utility model relates to filtration technology, and more particularly to a sucralose wastewater filtration device. Background Technology

[0002] Sweeteners are food additives that impart a sweet taste to food. Based on their source, they can be divided into natural additives and artificial additives. There are many types of natural additives, with extraction from sucrose being the most common method. With societal development, natural additives can no longer meet people's needs, leading to the development of artificial additives. Currently, the most commonly used artificial food sweetener is sucralose. Sucralose is a colorless and odorless white solid, 600 times sweeter than sucrose, and it is also chemically stable and does not easily decompose.

[0003] Currently, the wastewater treatment method for sucralose production can be wet catalytic oxidation + membrane separation + MVR. However, due to the high content of organic matter and suspended solids in the wastewater, the filter membrane needs to be replaced regularly. Although most existing technologies use threads for tightening, the large diameter of the filter cartridge makes manual tightening impossible, leading to leakage. Tools are required to complete the process. Therefore, a filtration device that allows for quick and easy disassembly of the filter membrane structure is needed. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figures 1 to 6 As shown, this sucralose wastewater filtration device of the present invention includes an inlet pipe 1, an outlet pipe 2, and multiple filtration mechanisms 3 for connecting the inlet pipe 1 and the outlet pipe 2.

[0024] Because the wastewater needs to be alkaline before filtration, it is reacted with an alkaline regulator and then a coagulant is added to generate a solid-liquid mixture, from which the supernatant is output. This supernatant contains colloidal particles and tiny suspended solids, so it needs to be filtered before electrodialysis treatment.

[0025] The filtration mechanism 3 is equipped with an inlet branch pipe 4, a drain branch pipe 5, and a filter cylinder 6. The inlet branch pipe 4 is connected to the inlet pipe 1, and the drain branch pipe 5 is connected to the drain pipe 2. The inlet branch pipe 4 is located at the lower end of the filter cylinder 6, while the drain branch pipe 5 is located on the side of the filter cylinder 6. This allows the upper clear liquid to first enter the middle of the filter membrane 7, and then be filtered out through the filter membrane 7, reaching the filter chamber 8, and then being discharged through the drain branch pipe 5.

[0026] The filter cartridge 6 has a hollowed-out center to form a filter chamber 8. The filter chamber 8 contains a filter membrane 7 and a retaining assembly 9. The filter membrane 7 is fixed in the filter chamber 8 by the retaining assembly 9. The filter cartridge 6 has a fixing port 10, and an extension 11 is provided at the lower end of the fixing port 10. The extension 11 is used to restrict the position of the filter membrane 7. A locking hole 12 is provided on the inner wall of the fixing port 10.

[0027] Meanwhile, a sealing ring (not shown in the figure) can be installed between the base 13 and the filter membrane 7, and between the filter membrane 7 and the lower inner wall of the filter chamber 8, to improve the sealing effect, prevent leakage, and improve the filtration effect, preventing unfiltered liquid from being discharged from the gap.

[0028] The retaining assembly 9 consists of a base 13, a cover plate 14, a pressing member 15, and multiple locking members 16 disposed in the middle of the base 13. The pressing member 15 extends through the cover plate 14 to the outside. A first spring 17 is provided at the lower end of the pressing member 15. A second spring 18 is fitted on the locking member 16. The inner wall of the filter cylinder 6 is provided with a locking hole 12 that mates with the locking member 16. When the pressing member 15 is pressed, the second spring 18 pushes the locking member 16, keeping the locking member 16 disengaged from the locking hole 12.

[0029] The lower end of the cover plate 14 is provided with an inner ring 19, and the inner ring 19 is provided with multiple notches 20 that cooperate with the locking member 16. The notches 20 are used to restrict the position of the locking member 16, so that the locking member 16 can slide in the notches 20.

[0030] The locking member 16 consists of a sliding block 21 and a locking rod 22. The sliding block 21 is provided with a blocking part 23, and the second spring 18 is sleeved on the locking rod 22. The blocking part 23 is used to block the position of the sliding block 21 so that it does not cross the blocking ring 24, thereby limiting the sliding stroke of the locking member 16.

[0031] The pressing member 15 consists of a first rod 25, a conical body 26, and a second rod 27. The cover plate 14 has a through hole 28 that mates with the first rod 25. The first rod 25 has a pressing block 29 with an external thread 30, and the pressing block 29 has an internal thread 31 that mates with the external thread 30. The conical body 26 has a first conical surface 32, and the sliding block 21 has a second conical surface 33 that mates with the first conical surface 32. When the pressing member 15 is pressed, the second conical surface 33 slides on the first conical surface 32, keeping the pressing member 15 pressing the first spring 17, compressing it. The elastic force of the second spring 18 pushes the sliding block 21, keeping the sliding block 21 sliding towards the conical body 26.

[0032] The length of the second rod 27 is less than the length of the first spring 17 in its natural state, so that the second rod 27 can move in the middle of the first spring 17. After the pressing member 15 presses, the second rod 27 is kept in the middle of the first spring 17, so that when the second rod 27 is placed on the lower inner wall of the moving area, the position of the pressing member 15 is restricted, so that it cannot be pressed down further.

[0033] The base 13 consists of an outer ring 34 and an extension 35. The middle of the outer ring 34 forms an active area 36, ​​and the middle of the extension 35 forms a movable area 37. The outer ring 34 is provided with a through hole 38 that cooperates with the locking rod 22, and the active area 36 is provided with a blocking ring 24 that cooperates with the blocking part.

[0034] During installation, first, install the T-shaped sealing ring between the upper and lower ends of the filter membrane 7. The center of the sealing ring is through to facilitate liquid passage. Then, place the filter membrane 7 into the fixing port 10, press the pressing member 15, and then apply pressure to the retaining component 9, causing it to squeeze the sealing ring. Then, release the external force pressing the pressing member 15, and the locking rod 22 enters the locking hole 12 for positioning. At this point, the retaining component 9 is installed in the fixing port 10 under the reverse force of the sealing ring. Therefore, the filter membrane 7 can be positioned while preventing leakage.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
