[0001] This utility model relates to the field of medicinal residue treatment technology, specifically a medicinal residue residual liquid extrusion device. Background Technology

[0002] Medicinal residue is the solid substance remaining after a drug has been extracted or decocted. It contains insoluble components of the medicinal material and drug components that have not been completely extracted. The residual liquid inside the residue still has strong medicinal properties, so it is necessary to squeeze out the residual liquid from the residue.

[0003] Existing medicinal residue compression devices use conveyor belt compression to squeeze out the residual medicinal liquid from the residue. However, some medicinal materials are hard and can damage the conveyor belt during compression, leading to a reduction in the conveyor belt's lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a device for squeezing medicinal residue to solve the problems mentioned in the background art.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution: such as Figure 1 - Figure 6 The device for squeezing medicinal residue includes a squeezing box 1, an squeezing conveyor belt 2 inside the squeezing box 1, a lifting squeezing rod 3 rotatably connected to one end of the squeezing conveyor belt 2, a sliding groove 4 near the lifting squeezing rod 3 in the squeezing box 1, two sets of sliding grooves 4 arranged symmetrically, a lower pressure block 5 abutting against the outside of the lifting squeezing rod 3 near the sliding groove 4, a lower pressure spring 6 fixedly connected to the end of the lower pressure block 5 away from the lifting squeezing rod 3, a positioning block 9 fixedly connected to the end of the lower pressure spring 6 away from the lower pressure block 5, a rotating sleeve 10 rotatably connected to the outside of the positioning block 9, a nut 8 fixedly connected to the end of the rotating sleeve 10 away from the positioning block 9, a threaded rod 7 rotatably connected inside the nut 8, and the threaded rod 7 fixedly connected inside the sliding groove 4 away from the lower pressure block 5.

[0021] During operation, when squeezing out residual liquid from medicinal materials, some materials are quite hard. When the lifting squeezing rod 3 drives the squeezing conveyor belt 2 to squeeze, if a certain pressure value is exceeded, the lower pressure spring 6 will be compressed. At this time, the lifting squeezing rod 3 rises, thus ensuring that the harder materials can be discharged. After the harder materials are discharged, the lower pressure spring 6 pushes the lower pressure block 5 to reset the lifting squeezing rod 3, thus continuing the squeezing process. When it is necessary to adjust the limit of the downward pressure, the nut 8 can be rotated outside the threaded rod 7, and the rotating sleeve 10 will rotate outside the positioning block 9. This will cause the lower pressure spring 6 to contract, thus ensuring the downward pressure of the lifting squeezing rod 3 and the rebound force of the lower pressure spring 6. This achieves the control and adjustment of the downward pressure of the lifting squeezing rod 3, solving the problem that some raw materials are quite hard and will damage the squeezing conveyor belt 2 during squeezing, leading to a reduction in the service life of the squeezing conveyor belt 2, and thus improving the service life of the squeezing conveyor belt 2.

[0022] Please see Figure 3 , Figure 4 and Figure 5 In the diagram, a dregs conveyor belt 16 is installed inside the extrusion box 1 near the extrusion conveyor belt 2. A motor 17 is fixedly connected to the outside of the extrusion box 1. The output end of the motor 17 is externally rotatably connected to the inside of the dregs conveyor belt 16. A drive gear 22 is fixedly connected to the output end of the motor 17. The drive gear 22 is rotatably connected to the outside of the extrusion box 1. A driven gear 23 meshes with the drive gear 22. A driven rod 24 is fixedly connected to the side of the driven gear 23 near the extrusion box 1. The driven rod 24 is rotatably connected inside the extrusion conveyor belt 2 at a position away from the lifting extrusion rod 3.

[0023] During operation, the motor 17 drives the dregs conveyor belt 16 to rotate, thereby allowing the dregs conveyor belt 16 to transport the dregs. When the motor 17 is driven, it drives the drive gear 22 to rotate, which in turn drives the driven gear 23 to rotate in the opposite direction. The driven gear 23 drives the driven rod 24 to rotate, thereby allowing the extrusion conveyor belt 2 to gradually extrude the dregs. This achieves a stable extrusion and extrusion effect for the dregs, solves the problem of needing two sets of drive sources for extrusion and transport, and improves the driving effect of dregs transport.

[0024] Please see Figure 1 , Figure 2 and Figure 4In the diagram, a positioning extrusion rod 21 is rotatably connected to the inside of the extrusion conveyor belt 2 near the center. Both ends of the positioning extrusion rod 21 are rotatably connected to the inside of the extrusion conveyor belt 2. The driven rod 24, the positioning extrusion rod 21, and the lifting extrusion rod 3 are arranged at an angle. A drain port 19 is opened on the outside of the extrusion box 1. A drain plate 18 is fixedly connected to the inside of the extrusion box 1 near the drain port 19. The drain plate 18 is arranged at an angle. A support block 13 is abutted on the side of the lifting extrusion rod 3 away from the lower pressure block 5. A support spring 15 is fixedly connected to the side of the support block 13 away from the lifting extrusion rod 3. The end of the support spring 15 away from the support block 13 is fixedly connected to the inside of the sliding groove 4. A telescopic rod 14 is fixedly connected to the side of the support block 13 near the support spring 15. The telescopic rod 14 is fixedly connected to the opposite side of the support block 13 and the sliding groove 4.

[0025] During operation, when the extrusion conveyor belt 2 is extruding, the progressively tilting structure of the driven rod 24, the positioning extrusion rod 21, and the lifting extrusion rod 3 can progressively extrude the dregs, preventing them from entering the space between the extrusion conveyor belt 2 and the dregs conveyor belt 16. The extruded liquid from the extrusion conveyor belt 2 and the dregs conveyor belt 16 will be discharged along the drain plate 18, and the discharged liquid will be collected and processed from the drain port 19. The telescopic rod 14 and the support spring 15 push the support block 13 to support the lifting extrusion rod 3, achieving stable control of the position of the lifting extrusion rod 3 and cleaning the dregs on the surface of the dregs conveyor belt 16. This solves the problem that a single downward pressure spring 6 pushing the downward pressure block 5 to rotate causes the lifting extrusion rod 3 to be damaged due to too sudden reset, thus improving the stability of the rotation and extrusion of the lifting extrusion rod 3.

[0026] Please see Figure 1 , Figure 3 and Figure 4 In the diagram, a pusher 20 is fixedly connected inside the extrusion box 1 near the outside of the dregs conveyor belt 16. A lower scraper 25 is fixedly connected inside the extrusion box 1 away from the pusher 20. The lower scraper 25 is set at an angle, and the end of the lower scraper 25 away from the extrusion box 1 abuts against the outside of the dregs conveyor belt 16. An installation clip 11 is rotatably connected to the outside of the lifting extrusion rod 3. An upper scraper 12 is fixedly connected to the side of the installation clip 11 near the extrusion conveyor belt 2. The end of the upper scraper 12 near the installation clip 11 abuts against the outside of the extrusion conveyor belt 2.

[0027] During operation, the pusher 20 makes it easier to push the dregs into the space between the extrusion conveyor belt 2 and the dregs conveyor belt 16. The dregs on the surface of the dregs conveyor belt 16 can be scraped off by the lower scraper 25. When the extrusion conveyor belt 2 is in use, the mounting clip 11 is clipped onto the outside of the lifting extrusion rod 3, allowing the upper scraper 12 to contact the surface of the extrusion conveyor belt 2, thereby cleaning the dregs attached to the surface of the extrusion conveyor belt 2. This achieves the effect of cleaning the surfaces of the extrusion conveyor belt 2 and the dregs conveyor belt 16, solving the problem that the dregs on the surfaces of the extrusion conveyor belt 2 and the dregs conveyor belt 16 affect the extrusion effect of the subsequently added dregs, and improving the extrusion effect of the residual liquid inside the dregs.

[0028] Working principle: When squeezing out residual liquid from medicinal materials, some materials are harder. When the lifting squeezing rod 3 drives the squeezing conveyor belt 2 to squeeze, the lower pressure spring 6 will be compressed when a certain pressure value is exceeded. At this time, the lifting squeezing rod 3 rises, thus ensuring that the harder materials can be discharged. After the harder materials are discharged, the lower pressure spring 6 will push the lower pressure block 5 to reset the lifting squeezing rod 3, thus continuing the squeezing process. When it is necessary to adjust the limit of the downward pressure, the nut 8 can be rotated outside the threaded rod 7, and the rotating sleeve 10 will rotate outside the positioning block 9. This will cause the lower pressure spring 6 to contract, thus ensuring the downward pressure of the lifting squeezing rod 3 and the rebound force of the lower pressure spring 6, thereby controlling the lifting squeezing rod. Adjusting the downward pressure of component 3 solves the problem of some medicinal materials having a hard texture, which can damage the extrusion conveyor belt 2 during extrusion, leading to a reduced service life of the extrusion conveyor belt 2. This adjustment improves the service life of the extrusion conveyor belt 2. Motor 17 drives the dregs conveyor belt 16 to rotate, thus transporting the dregs. When driven, motor 17 drives drive gear 22 to rotate, which in turn drives driven gear 23 to rotate in the opposite direction. Driven gear 23 then drives driven rod 24 to rotate, allowing the extrusion conveyor belt 2 to gradually extrude the dregs. This achieves a stable extrusion and extrusion effect, solving the problem of needing two sets of drive sources for extrusion and transport, and improving the efficiency of dregs transport. The conveyor belt 2 provides a driving effect. During the compression process, the progressively tilting structure of the driven rod 24, positioning compression rod 21, and lifting compression rod 3 gradually compresses the medicinal residue, preventing it from entering the area between the compression conveyor belt 2 and the medicinal residue conveyor belt 16. The compressed medicinal liquid from the compression conveyor belt 2 and the medicinal residue conveyor belt 16 is discharged along the drain plate 18, and the discharged liquid is collected and processed from the drain port 19. The telescopic rod 14 and the support spring 15 push the support block 13 to support the lifting compression rod 3, achieving stable control of the position of the lifting compression rod 3 and cleaning the medicinal residue on the surface of the medicinal residue conveyor belt 16. This solves the problem of a single downward spring 6 pushing the downward pressure block 5 to rotate, which could cause the reset to be too sudden and disrupt the lifting and lowering mechanism. The problem of damage to the extrusion rod 3 has been addressed by improving the stability of the rotation and extrusion of the lifting extrusion rod 3. The pusher platform 20 makes it easier to push the dregs into the space between the extrusion conveyor belt 2 and the dregs conveyor belt 16. The dregs on the surface of the dregs conveyor belt 16 can be scraped off by the lower scraper 25. When the extrusion conveyor belt 2 is in use, the mounting clip 11 is clipped onto the outside of the lifting extrusion rod 3, allowing the upper scraper 12 to contact the surface of the extrusion conveyor belt 2, thereby cleaning the dregs adhering to the surface of the extrusion conveyor belt 2 and the dregs conveyor belt 16. This solves the problem of dregs on the surface of the extrusion conveyor belt 2 and the dregs conveyor belt 16 affecting the extrusion effect of the subsequently added dregs, and improves the extrusion effect of the residual medicine inside the dregs.
