[0002] Due to its own characteristics during the production process of lindera aggregata, its extract contains impurities. Therefore, during the process of extracting its extract (alkaloid), a multi-stage filtration device needs to be used to gradually filter the extract to remove impurities.

[0003] During the long-term use of traditional filtration devices, various impurities will gradually accumulate on the filter plate. These impurities will not only block the holes on the filter plate, but also reduce the filtration efficiency, thereby affecting the performance of the entire filtration system. Most of the common filtration devices on the market currently use fixed filter plates. When the impurities on the filter plate accumulate to a certain extent, it is necessary to manually disassemble them for cleaning one by one. This process is not only time-consuming and laborious, but also the frequent disassembly and assembly operations are likely to damage the filter plate and shorten its service life. Summary of the Utility Model

[0029] The following will describe in detail some implementation manners of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] Please refer to Figures 1 - 8 , the embodiment of the present utility model provides a lindera alkaloid filtration and separation device, including a filter housing 1 and a liquid inlet pipe 3 and a liquid outlet pipe 4 arranged on the upper and lower sides of the filter housing 1. Among them, the liquid outlet pipe 4 is connected to the liquid outlet of the filter housing 1 through a fixed sleeve 5, and the fixed sleeve 5 is fixed by bolts. After cleaning the impurities, the liquid outlet pipe 4 can be disassembled to facilitate the discharge of impurities from the bottom of the filter housing 1.

[0031] The inlet pipe 3 is connected to the outlet of the hydrochloric acid adding mechanism 26. The hydrochloric acid adding mechanism 26 adds acid to the liquid that has not entered the filtration housing 1 to adjust its pH value. The adjusted liquid enters the filtration housing 1, and then the acid-added liquid is preliminarily filtered.

[0032] After the liquid is filtered by the filter element on the upper side of the filtration housing 1, the ammonia adding mechanism 2 installed at the part of the filtration housing 1 close to the lower side adds ammonia to the liquid, and the filter element located on the lower side of the filtration housing 1 performs secondary filtration on the liquid after ammonia is added to achieve solid-liquid separation, so that the filter residue, that is, the filter cake, stays on the filter plate 8 at the bottom, and finally the sediment filter cake is obtained. Then a box door is opened on the lower side of the filtration housing 1, and the filter cake can be taken outwards to obtain the separated solid filter cake, and the filtered liquid added with ammonia can be discharged from the outlet pipe 4.

[0033] And when the sediment is stationary in the filtration housing 1, the stationary time is obtained through the timer 27. The timer 27 can use equipment such as an alarm clock.

[0034] In order to achieve multi-stage filtration, at least three filter plates 8 are sequentially installed on the upper side of the filtration housing 1. Both sides of the filter plate 8 are located in the installation grooves 6 opened on the inner side of the filtration housing 1. At the same time, a first spring 7 connected to the lower side of the filter plate 8 is arranged inside the installation groove 6. After the filter plate 8 receives the force from top to bottom, the first spring 7 can be compressed, and the filter plate 8 is reset by the elasticity of the first spring 7, which is convenient for cleaning the impurities in the filter plate 8.

[0035] Considering that there are blockages and impurities in the holes of the filter plate 8 after long-term use, empty grooves 13 are opened on the inner walls of the filtration housing 1 on both sides of each filter plate 8. An impurity cleaning mechanism is installed in the empty grooves 13. The impurity cleaning mechanism is located above the filter plate 8 and prevents blockage by intermittently knocking on the filter plate 8.

[0036] Specifically, the impurity cleaning mechanism includes a knocking rod 15 located in the empty groove 13. The tail end of the knocking rod 15 is located outside the filtration housing 1, and a knocking head is arranged at one end of the knocking rod 15 extending into the interior of the filtration housing 1. The knocking head is located above the filter plate 8.

[0037] A sealing gasket 21 is arranged at one end of the knocking rod 15 close to the knocking head. When the filter plate 8 is not cleaned, the sealing gasket 21 is located inside the empty groove 13 to seal the empty groove 13 and prevent the extraction liquid from overflowing. When the filter plate 8 is cleaned, the knocking rod 15 is pushed inwards to make the sealing gasket 21 enter the inner side of the filtration housing 1, and the knocking rod 15 can be used.

[0038] In order to ensure that the knocking rod 15 can be pushed and reset after being forced to press down, a sliding groove 14 is provided inside the empty groove 13. A slider 16 is slidably connected in the sliding groove 14. A second spring 17 is connected between the slider 16 and the knocking rod 15. When the knocking rod 15 is forced to press down, it causes the second spring 17 to be compressed. When not under force, the second spring 17 drives the knocking rod 15 to reset through elastic expansion and contraction. At the same time, through the sliding of the slider 16, when the knocking rod 15 is pushed, the second spring 17 moves along with it.

[0039] In order to ensure the sealing performance of the filter housing 1, a hollow sealing sleeve 18 is provided on one side of the empty groove 13 of the filter plate 8. A sliding plate 20 is slidably connected inside the sealing sleeve 18. The upper side of the sliding plate 20 is in contact with the lower side of the rod body of the knocking rod 15. The sliding plate 20 and the sealing sleeve 18 are used to seal one side of the empty groove 13. A sealing gasket 21 is located inside the sealing sleeve 18.

[0040] When the knocking rod 15 is forced to press down, the sliding plate 20 slides into the sealing sleeve 18. In order to make the sliding plate 20 automatically reset, a third spring 19 is provided inside the sealing sleeve 18. The upper end of the third spring 19 is connected to the lower side of the sliding plate 20. The elasticity of the third spring 19 is used to cause the sliding plate 20 to reset following the reset of the knocking rod 15.

[0041] In summary, it is necessary to press down the knocking rod 15 to make the knocking rod 15 knock the filter plate 8. Therefore, cylinders 22 are symmetrically installed at the upper end of the filter housing 1. The piston end of the cylinder 22 is connected to the upper end of the connecting rod 23. At least three pressing heads 24 are provided on one side of the connecting rod 23. The three pressing heads 24 are respectively located above the tails of the three knocking rods 15, and there is a certain distance between the pressing heads 24 and the knocking rods 15. When the cylinder 22 moves downward, the pressing heads 24 press down on the knocking rods 15. At this time, the knocking rods 15 knock the filter plate 8. When the cylinder 22 moves upward, the pressing heads 24 move away from the knocking rods 15. The elasticity of the third spring 19 and the second spring 17 causes the knocking rods 15 to move back and forth in this way, realizing intermittent knocking and discharging the impurities in the filter plate 8.

[0042] Furthermore, during the process of cleaning the filter plate 8 mentioned above, washing with water can be used in combination to improve the cleaning effect. Therefore, a conical sleeve 9 is provided inside the upper end of the filter housing 1. An annular pipe 10 is installed at the bottom of the conical sleeve 9. One end of the annular pipe 10 is connected to the water inlet pipe. The water inlet pipe is used to connect to an external water source, and the water inlet of the water inlet pipe is located outside the filter housing 1.

[0043] And two long pipes 11 arranged in a cross shape are connected inside the annular pipe 10. Nozzles 12 are installed on both the annular pipe 10 and the long pipes 11 to expand the range of flushing the filter plate 8.

[0044] In addition, a flow dividing plate 25 is arranged inside the conical sleeve 9. The flow dividing plate 25 is located above the long pipe 11 and covers the long pipe 11. The conical sleeve 9 covers the annular pipe 10 to prevent the extraction liquid from contacting the long pipe 11 and the annular pipe 10 during filtration. At the same time, the side of the flow dividing plate 25 is designed in an arc shape, which can promote the flow of the extraction liquid, divide the extraction liquid, and improve the filtration efficiency.

[0045] Among them, the installation methods and cleaning methods of the upper and lower groups of filter elements are the same.

[0046] In summary, the working principle of a lindera aggregata alkaloid filtration and separation device according to an embodiment of the present invention is as follows: When cleaning the filter plate 8, first, the filter plate 8 is flushed through the spray heads 12 on the annular pipe 10 and the long pipe 11, and the knocking rod 15 is pushed to the inside of the filter housing 1. The air cylinder 22 drives the pressing head 24 to push the knocking rod 15 downward at intervals, so that the knocking rod 15 knocks on the filter plate 8 to promote the discharge of impurities in the holes of the filter plate 8. While the knocking rod 15 is knocking, it also knocks on the second spring 17 and the third spring 19. After the pressing head 24 is lifted upward, the second spring 17 causes the knocking rod 15 to reset, and the third spring 19 causes the sliding plate 20 to reset. The filter plate 8 is elastically reset by the first spring 7, and this process is repeated to achieve the purpose of cleaning impurities.

[0047] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
