Description

Technical Field

[0001] This utility model belongs to the field of melatonin purification technology, specifically relating to a melatonin production and purification device. Background Technology

[0002] L-Tryptophan is one of the eight essential amino acids for the human body. In the body, tryptophan can be converted into important physiologically active substances such as 5-hydroxytryptamine, indoleacetic acid, nicotinic acid, alkaloids, and coenzymes, which participate in regulating protein synthesis and play an important role in the growth, development, and metabolism of humans and animals. After the surface oxidation activated carbon is mixed and stirred for adsorption, it needs to be filtered out. The traditional filtration method is to perform pressure filtration followed by fine filtration. However, before each pressure filtration, the activated carbon particles need to be filtered out to avoid damage to the filter cloth. This means that the filtration process needs to be carried out three times: coarse filtration, medium filtration by pressure plate, and fine filtration by filter membrane. At the same time, the conveying pipeline before pressure filtration is prone to activated carbon blockage and is difficult to clean. Utility Model Content

The filter element 13 is disposed inside the coarse filter barrel 11, with both ends tightly attached to the inner wall of the coarse filter barrel 11 and the connecting device 2, respectively. The top sealing device 14 is connected inside the coarse filter barrel 11 and is connected to the rinsing pipe 17. The filter element 13 is fitted on the upper side, the collection hopper 15 is connected to the lower side of the coarse filter barrel 11, the discharge pipe 16 is connected to the collection hopper 15, and the positioning pipe 17 is connected to the inner wall of the coarse filter barrel 11 with one end inserted into the filter element 13 and the other end connected to the flushing pump 4; the connecting device 2 includes a second connecting post 21, a right connecting thread groove 22, a left connecting thread groove 23, a sealing gasket 24, a liquid guide pipe 25, and a positioning plate 28. The right connecting thread groove 22 and the left connecting thread groove 23 are respectively opened on both sides of the second connecting post 21 and fit with the coarse filter barrel 11 and the fine filter device 3. One end of the liquid guide pipe 25 is set in the filter element 13 and the other end passes through the second connecting post 21. The two sealing gaskets 24 are respectively fitted on the filter element 13. On the liquid guide tube 25 and the positioning tube 17, the positioning plate 28 is set in the right connecting thread groove 22, and the positioning plate 28 is evenly provided with a plurality of through holes; the fine filtration device 3 includes a fine filtration barrel 31, a partition plate 32, a sealing ring 33, a liquid outlet tube 34, a filter membrane element 35 and a positioning pressure plate 36. The partition plate 32 is connected to the fine filtration barrel 31, the positioning pressure plate 36 is set in the fine filtration barrel 31, a plurality of filter membrane elements 35 are set between the partition plate 32 and the positioning pressure plate 36, and both ends of the filter membrane element 35 are connected to the sealing ring 33. The partition plate 32 is provided with a plurality of liquid guide holes for positioning the sealing ring 33, and the positioning pressure plate 36 is provided with a plurality of positioning holes for positioning the sealing ring 33. The positioning plate 36 between adjacent positioning slots has an inlet hole, and the outlet pipe 34 is connected to the end of the fine filter barrel 31 near the partition plate 32; the upper sealing device 14 includes an arc-shaped baffle 18, which is connected inside the coarse filter barrel 11 and fits against the upper side of the filter element 13; both sides of the arc-shaped baffle 18 are provided with rolled edges 19, and a first connecting post 110 is provided inside the rolled edge 19, and a sealing membrane 111 is connected between the two first connecting posts 110; the liquid guide pipe 25 has a plurality of liquid guide holes 26; the second connecting post 21 and the fine filter barrel 31 are respectively connected with a connecting handle 27 and a handle ring 37; the discharge pipe 16 and the fine filter barrel 31 are provided with a drain valve.

[0024] The liquid feed is introduced into the coarse filter tank 11 through the feed pipe 12 and coarsely filtered through the filter element 13. Then, it enters the right connecting threaded groove 22 through the liquid guide pipe 25, and then enters the fine filter tank 31 through the through holes on the positioning plate 28 and the liquid inlet holes on the positioning pressure plate 36. Finally, it undergoes fine filtration through the filter membrane element 35. The filtrate from the fine filtration enters through the liquid guide holes on the partition plate 32 and is discharged through the liquid outlet pipe 34 on the other side of the partition plate 32, completing the filtration process. The arc-shaped baffle 18 prevents activated carbon particles in the liquid feed introduced through the feed pipe 12 from falling onto the upper surface of the filter element 13, which would make it difficult to flush down the filter element 13 during backwashing. Washing the lower surface of the filter element 13 makes it easier for the filtered carbon powder layer to detach. The detached carbon powder falls into the collection hopper 15 and is then discharged through the discharge pipe 16. The sealing membrane 111 adheres tightly to the upper surface of the filter element 13, reducing the amount of carbon powder entering its upper surface. When replacing filter element 13, control the connecting handle 27 to rotate the second connecting column 21, causing the second connecting column 21 to disengage from the coarse filter barrel 11. The coarse filter barrel 11 is then threadedly connected to the left connecting thread groove 23. Then, filter element 13 can be replaced. When replacing filter membrane element 35, control the handle ring 37 to rotate the fine filter barrel 31, causing the fine filter barrel 31 to disengage from the second connecting column 21. Then, remove the positioning pressure plate 36 from the fine filter barrel 31. Then, filter membrane element 35 can be replaced. The sealing rings 33 at both ends of the filter membrane element 35 are positioned by the positioning groove on the positioning pressure plate 36 and the liquid guiding hole on the partition plate 32, so that several filter membrane elements 35 are not misaligned during installation. When backwashing the filter membrane element 35 and filter element 13, the flushing liquid in the flushing pipe is pressurized and introduced into the filter element 13 and filter membrane element 35 by the flushing pump 4 for backwashing. After flushing, the backwash material is discharged by opening the drain valve.
