DETAILED DESCRIPTION

[0038] Driven by the driving motor 2, the impurity removal component 3 will rotate, so that the impurity removal scraper 301 can scrape off the impurities remaining on the top of the cone skirt ring plate 401 and the filter cone plate 402, and the centrifugal force generated by the rotation of the Suzhou and Zhejiang impurity removal scraper 301, the impurities and part of the extract will slowly move to the edge, so that they can enter the slag discharge channel 6 through the lower slag hole 4011, thereby cleaning the impurities on the top of the cone skirt ring plate 401 and the filter cone plate 402, improving the filtration efficiency of the extract, and when the cone skirt ring plate 401 and the filter cone plate 402 move up and down, the tension spring 303 and the telescopic rod 304 will be telescoped and released, so that the impurity removal scraper 301 can adapt to the height changes of the cone skirt ring plate 401 and the filter cone plate 402.

[0039] Furthermore, the impurity removal component 3 also includes a slag pressing roller 309, and roller frames 308 are rotatably provided at both ends of the slag pressing roller 309. A receiving bracket 307 is symmetrically fixedly provided on the top of the roller frame 308. The receiving bracket 307 is fixedly provided on the top of the impurity removal scraper 301.

The impurity removal component 3 is arranged at the top of the filtering component 4, and the middle bearing shaft 201 is arranged to pass through the filtering cone plate 402.

[0040] When the impurity removal component 3 rotates, the slag pressing roller 309 can roll on the top of the cone skirt ring plate 401 and the filter cone plate 402 during rotation, thereby pressing out the Chinese medicinal liquid rich in the impurities, fully improving the utilization value of the extract, and the scraper roller arc plate 310 is always in contact with the slag pressing roller 309, thereby scraping off the impurities attached to the surface of the slag pressing roller 309, so that the slag pressing roller 309 can continuously achieve the rolling effect.

[0041] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, and also includes a filter component 4 for filtering the extract, the filter component 4 is arranged inside the filter cartridge 1, the filter component 4 includes a cone skirt ring plate 401 and a filter cone plate 402, the cone skirt ring plate 401 is fixedly arranged on the outer side of the filter cone plate 402, and a plurality of primary filter holes are opened on the top of the filter cone plate 402.

[0042] When the extract falls on the top of the filter cone plate 402 , the liquid in the extract will flow down through the primary filter holes on the top of the filter cone plate 402 , and the impurities in the extract will remain on the top of the filter cone plate 402 .

[0043] Among them, a lower slag hole 4011 is opened at the top of the cone skirt ring plate 401, a filter ring frame 4012 is fixedly arranged on the outer side of the cone skirt ring plate 401, a connecting ring pad 4014 is fixedly arranged on the outer side of the bottom end of the filter ring frame 4012, the connecting ring pad 4014 is made of rubber material, an annular filter pocket 4015 is fixedly arranged on the outer side of the connecting ring pad 4014, the cone skirt ring plate 401 is fixedly arranged on the inner side of the filter cylinder 1, and a secondary filter hole is opened on the inner side of the annular filter pocket 4015, and the diameter of the secondary filter hole is smaller than that of the primary filter hole.

[0044] Since the filter assembly 4 is overall conical in shape, the extract will flow toward the periphery of the filter assembly 4, so that the liquid will enter the annular filter pocket 4015 through the filter ring frame 4012. The annular filter pocket 4015 can filter out finer impurities, further improving the quality of the Chinese medicine liquid. When the cone skirt ring plate 401 and the filter cone plate 402 are lifted, the connecting ring pad 4014 will be stretched to adapt to the height changes of the cone skirt ring plate 401 and the filter cone plate 402.

[0045] It should be noted that, refer to Figure 4 and Figure 5 A bottom connection platform 5 is fixedly provided at the bottom end of the filter cone plate 402, and an arc-surface protrusion 501 is symmetrically provided at the bottom end of the bottom connection platform 5. A roller 502 is symmetrically and rollingly provided at the bottom end of the bottom connection platform 5. The roller 502 is rotatably provided on the outside of the middle bearing shaft 201. A slider 4013 is fixedly provided on the outside of the top end of the filter ring frame 4012, and a return spring 4016 is fixedly provided on the top end of the slider 4013. A sliding shell 4017 is fixedly provided on the other end of the return spring 4016. The slider 4013 is slidably provided on the inner side of the sliding shell 4017, and the sliding shell 4017 is fixedly provided inside the filter cartridge 1.

[0046] Among them, the middle bearing shaft 201 is set through the bottom connecting platform 5. When the middle bearing shaft 201 rotates, it will drive the roller 502 to rotate, so that the roller 502 will roll on the bottom of the bottom connecting platform 5 and the arc-surface protrusion 501. When the roller 502 contacts the arc-surface protrusion 501, the cone skirt ring plate 401 and the filter cone plate 402 will be lifted, causing the cone skirt ring plate 401 and the filter cone plate 402 to shake, thereby preventing impurities from being stuck in the primary filter hole.

[0047] In this embodiment, refer to Figure 1 and Figure 2 A driving motor 2 is arranged above the filter cartridge 1, a middle bearing shaft 201 is fixedly arranged at the driving end of the driving motor 2, a motor stand 202 is fixedly arranged at the top of the driving motor 2, the motor stand 202 is fixedly arranged at the top of the filter cartridge 1, and a pulley 103 is fixedly arranged on the outer side of the driving end of the driving motor 2.

[0048] The driving motor 2 can provide the components therein with the required power, thereby facilitating the filtration of the extract.

[0049] Embodiment 2:

[0050] Reference Figure 1 , Figure 2 and Figure 7 An external support arm 203 is fixedly provided on the outer side of the middle bearing shaft 201, and a first magnet 204 is fixedly provided on the other end of the external support arm 203. The first magnet 204 and the second magnet 605 are arranged on the same horizontal axis, and the first magnet 204 and the second magnet 605 are magnets of the same polarity. A slag discharge channel 6 is fixedly provided on the bottom end of the cone skirt ring plate 401, and a telescopic tube is provided at the connection between the slag discharge channel 6 and the cone skirt ring plate 401. The other end of the slag discharge channel 6 extends to the outside of the filter cylinder 1, and the slag discharge channel 6 is arranged at the position corresponding to the lower slag hole 4011. A fixed branch pipe 601 is fixedly provided on the outer side of the slag discharge channel 6, and a liquid outlet branch pipe 6011 is fixedly provided on the outer side of the fixed branch pipe 601. A slag blocking net 6012 is fixedly provided at the connection between the slag discharge channel 6 and the fixed branch pipe 601.

[0051] The extract entering the slag discharge channel 6 will contain some liquid and a large amount of impurities. With the rotation of the middle bearing shaft 201, the first magnet 204 and the second magnet 605 will attract each other, and the second magnet 605 will drive the movable plunger 606 to move. At this time, the liquid outlet branch pipe 6011 and the fixed branch pipe 601 and the slag discharge channel 6 are connected, and the impurities will be blocked on one side of the slag blocking net 6012, that is, inside the slag discharge channel 6. The movement of the movable plunger 606 will also generate a certain suction force, which will suck the liquid in the extract into the fixed branch pipe 601 and fall from the liquid outlet branch pipe 6011, thereby fully filtering out the liquid in the extract.

[0052] Furthermore, a second magnet 605 and a movable plunger 606 are slidingly arranged on the inner side of the fixed branch pipe 601, the second magnet 605 is fixedly arranged at one end of the movable plunger 606, and a sliding frame 604 is symmetrically fixedly arranged on the other end of the second magnet 605, a guide rail 602 is slidingly arranged on the side of the sliding frame 604 that is close to each other, and a return spring 603 is fixedly arranged on the side of the guide rail 602 that is away from each other, the return spring 603 is fixedly arranged on the inner side of the sliding frame 604, and the guide rail 602 is fixedly arranged on the outer side of the fixed branch pipe 601.

[0053] Among them, the movement of the second magnet 605 will drive the sliding frame 604 to move, and the pull-back spring 603 will be compressed. When the first magnet 204 leaves the magnetic attraction range of the second magnet 605, the second magnet 605 and the movable plunger 606 will return to their original positions through the rebound force of the pull-back spring 603, and the movable plunger 606 will generate thrust, that is, the action of blowing and sucking, thereby pushing out the impurities on one side of the slag blocking net 6012 to prevent blocking the filter holes on the slag blocking net 6012.

[0054] Reference Figure 1 and Figure 2 A feed channel 101 is provided at the top of the filter cartridge 1, and a feed auger 102 is rotatably provided inside the feed channel 101. One end of the feed auger 102 extends out of the feed channel 101, and a pulley 103 is fixedly provided at one end of the feed auger 102. The pulleys 103 are connected by belt transmission. A liquid outlet channel 104 is fixedly provided at the bottom end of the filter cartridge 1, and an outlet valve 105 is provided at the other end of the liquid outlet channel 104.

[0055] The Chinese herbal medicine extract can be put in from the feed channel 101. When the pulley 103 at the driving end of the driving motor 2 is driven to rotate, the pulley 103 at one end of the unloading auger 102 can be driven to rotate through the belt, and then the unloading auger 102 can rotate, so that the extract can fall evenly and reach the top of the filter component 4 for filtration. The filtered extract falls to the bottom of the filter cartridge 1, and the outlet valve 105 is opened to allow the liquid to flow out from the liquid outlet channel 104.

[0056] Embodiment three:

[0057] Reference Figure 2 and Figure 8 A liquid-throwing platform 702 is fixedly arranged on the outer side of the middle bearing shaft 201, and the liquid-throwing platform 702 is arranged below the filter assembly 4. A filter cartridge 7 is arranged on the outer side of the liquid-throwing platform 702, and the filter cartridge 7 is fixedly arranged on the inner side of the filter cartridge 1 through a fixing plate 701. A three-level filter hole is opened on the outer side of the filter cartridge 7, and the diameter of the three-level filter hole is smaller than that of the first-level filter hole.

[0058] The extract liquid flowing down through the primary filter hole at the top of the filter cone plate 402 will enter the filter cartridge 7 and flow onto the outside of the liquid-spinning table 702. As the middle bearing shaft 201 rotates, the liquid-spinning table 702 rotates and spins the extract on the outside of the liquid-spinning table 702 onto the inner wall of the filter cartridge 7. The liquid will pass through the tertiary filter holes, and the solid impurities will remain on the inner wall of the filter cartridge 7 and drop to the bottom of the filter cartridge 7 due to their own gravity, thereby further filtering the downstream extract.

[0059] Working principle: the Chinese medicine extract is continuously fed into the feed channel 101, and the driving motor 2 is started at the same time, so that the pulley 103 at the driving end can drive the pulley 103 at one end of the unloading auger 102 to rotate through the belt, and then the unloading auger 102 can rotate, so that the extract can fall evenly and reach the top of the filter component 4. At the same time, the driving motor 2 will drive the middle bearing shaft 201 to rotate, and the rotation of the middle bearing shaft 201 will drive the impurity removal component 3 to rotate, so that the extract on the top of the filter component 4 is evenly dispersed, and the solid impurities are scraped off, which is convenient for the filtration of the liquid;

[0060] When the impurity removal component 3 rotates, the impurity removal scraper 301 in the impurity removal component 3 will move around the top of the cone skirt ring plate 401 and the filter cone plate 402. Since the filter component 4 is configured as a cone as a whole, the extract will flow down at the top of the filter component 4 due to its own gravity, and the solid impurities remaining on the top of the filter cone plate 402 can enter the slag discharge channel 6 through the lower slag hole 4011 after being scraped by the impurity removal scraper 301, and the slag pressing roller 309 will roll on the top of the filter component 4 to crush the solid impurities, press out the liquid therein, and fully extract the liquid medicine therein, and the scraper roller arc plate 310 can scrape off the solid impurities attached to the outside of the slag pressing roller 309, so that the slag pressing roller 309 can always achieve the crushing effect;

[0061] It should be noted that when the cone skirt ring plate 401 and the filter cone plate 402 move up and down, the tension spring 303 and the telescopic rod 304 will contract and release to adapt to the height change of the impurity removal scraper 301 and the slag pressing roller 309, so that the impurity removal scraper 301 and the slag pressing roller 309 can continue to scrape and crush impurities;

[0062] When the middle bearing shaft 201 rotates, it will drive the roller 502 to rotate, so that the roller 502 will roll back on the bottom of the bottom connection platform 5 and the arc surface protrusion 501. When the roller 502 contacts the arc surface protrusion 501, the cone skirt ring plate 401 and the filter cone plate 402 will be lifted up. Since the connecting ring gasket 4014 is a rubber setting, the connecting ring gasket 4014 will be stretched and will not be disconnected from the annular filter pocket 4015. When the cone skirt ring plate 401 and the filter cone plate 402 are lifted up, the slider 4013 will slide in the slider 4013, and the return spring 4016 will be compressed. Through the elastic force of the return spring 4016, the cone skirt ring plate 401 and the filter cone plate 402 return to their original positions for the next lifting work. This reciprocating process causes the cone skirt ring plate 401 and the filter cone plate 402 to shake, preventing impurities from being stuck in the primary filter hole, thereby facilitating the cleaning of impurities and preventing the primary filter hole from being blocked.

[0063] When the extract flows through the filter ring frame 4012, impurities will be blocked, and the liquid will flow to the connecting ring pad 4014 and enter the annular filter pocket 4015. The secondary filter holes in the annular filter pocket 4015 will further filter the fine impurities in the extract, thereby improving the filtering quality of the extract.

[0064] The extract flowing down from the filter cone plate 402 will enter the filter cartridge 7 and flow to the outside of the liquid-spinning platform 702. With the rotation of the center bearing shaft 201, the liquid-spinning platform 702 will rotate and spin the extract on the outside of the liquid-spinning platform 702 onto the inner wall of the filter cartridge 7. The liquid will pass through the three-stage filter holes, and the solid impurities will remain on the inner wall of the filter cartridge 7 and fall to the bottom of the filter cartridge 7 due to their own gravity, thereby further filtering the downstream extract.

[0065] The extract entering the slag discharge channel 6 will contain some liquid and a large amount of impurities. As the middle bearing shaft 201 rotates, the first magnet 204 and the second magnet 605 will attract each other, and the second magnet 605 will drive the movable plunger 606 to move. At this time, the liquid outlet branch pipe 6011 and the fixed branch pipe 601 and the slag discharge channel 6 are connected, and the impurities will be blocked on one side of the slag blocking net 6012, that is, inside the slag discharge channel 6. The movement of the movable plunger 606 will also generate a certain suction force, sucking the liquid in the extract into the fixed branch pipe 601 and falling from the liquid outlet branch pipe 6011. The movement of the second magnet 605 will drive the sliding frame 604 to move, and the pull-back spring 603 will be compressed. When the first magnet 204 leaves the magnetic attraction range of the second magnet 605, the second magnet 605 and the movable plunger 606 will return to their original positions through the resilience of the pull-back spring 603, and the movable plunger 606 will generate thrust to push out the impurities on one side of the slag blocking net 6012 to prevent the filter holes on the slag blocking net 6012 from being blocked. It should be noted that the fixed branch pipe 601 is arranged at the bend of the slag discharge channel 6 to facilitate the liquid in the extract to flow down, thereby fully filtering the liquid in the extract.

[0066] The liquid being extracted falls to the bottom of the filter cartridge 1 , and the outlet valve 105 is opened to allow the liquid to flow out from the liquid outlet channel 104 .
