[0002] In the production process of traditional Chinese medicine preparations, filtration is a key link to ensure the purity and effectiveness of the medicinal liquid. Its importance is self-evident. Traditional Chinese medicine liquid filtration devices mostly use a single-layer physical screen as the filtration medium. Although it can meet basic filtration needs to a certain extent, it is often difficult to achieve ideal filtration effects when processing complex Chinese medicine liquids containing a large amount of tiny particles or colloidal substances. On the one hand, the structural design is simple and lacks an effective multi-stage filtration mechanism, resulting in large particles being intercepted, and small particles and soluble components being difficult to completely remove, affecting the purity and stability of the medicinal liquid. On the other hand, the filtration efficiency is low. Since the medicinal liquid passes through the screen slowly, the processing capacity is limited, and it is difficult to meet the needs of large-scale production. Therefore, we propose a Chinese medicine liquid filtration device to solve the above problems. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] The present application provides a Chinese medicine liquid filtration device, which is mainly used to solve the problems in the prior art, on the one hand, that the structural design is simple and there is a lack of an effective multi-stage filtration mechanism, which results in that after large particles are trapped, fine particles and soluble components are difficult to be completely removed, affecting the purity and stability of the medicinal liquid; on the other hand, the filtration efficiency is low, and the processing capacity is limited due to the slow speed of the medicinal liquid passing through the screen, which makes it difficult to meet the needs of large-scale production. The following technical solutions are provided. Figure 1-Figure 4 Give detailed instructions:

[0025] A Chinese medicine liquid filtering device, comprising:

[0026] The installation cylinder 1 has a discharge pipe 101 connected to the bottom of one side of the installation cylinder 1;

[0027] The cylinder cover 2 is buckled on the upper end of the installation cylinder 1, and a feed pipe 201 is rotatably embedded in the middle of the top of the cylinder cover 2;

[0028] A locking member 3 is provided on the outside of the mounting tube 1 and is used to fix the tube cover 2 on the mounting tube 1;

[0029] The filter cartridge 4 is disposed inside the mounting cartridge 1. A circular array of strip discharge holes 401 is constructed on the surface of the filter cartridge 4. The top of the filter cartridge 4 is an open structure, and a cross 5 is fixedly installed in the upper end. Filter screens 6 of different diameters are fixedly installed at equal intervals between the inner bottom wall of the filter cartridge 4 and the cross 5. The mesh aperture of the filter screen 6 decreases as it approaches the edge of the filter cartridge 4. A circular hole 501 is constructed in the middle of the cross 5. The lower end of the feed pipe 201 passes through the circular hole 501 and extends into the innermost filter screen 6.

[0030] The turntable 7 is arranged at the bottom side of the installation cylinder 1 and is used to drive the filter cylinder 4 to rotate.

[0031] Workflow Description:

[0032] First, pour the Chinese medicine liquid to be filtered into the filter cylinder 4 through the feed pipe 201;

[0033] The turntable 7 drives the filter cylinder 4 to rotate, using centrifugal force to promote the separation of the drug liquid and the drug residue;

[0034] The liquid medicine is filtered through filter screens 6 of different diameters in multiple stages, and fine particles and soluble components are completely removed;

[0035] The filtered liquid medicine flows out from the strip discharge hole 401 , falls into the installation cylinder 1 , and is finally discharged through the discharge pipe 101 .

[0036] After the filtration is completed, the turntable 7 is closed and the filter cartridge 4 is disassembled for cleaning and maintenance.

[0037] Working principle:

[0038] The Chinese medicine liquid filtering device realizes multi-stage filtration by fixing filter screen covers 6 of different diameters at equal intervals between the inner bottom wall of the filter cylinder 4 and the cross 5. During the rotation of the medicinal liquid in the filter cylinder 4, the medicinal liquid is subjected to the action of centrifugal force, and large particles are retained on the outer filter screen cover 6, while fine particles and soluble components pass through the inner filter screen cover 6 to enter the next stage of filtration. After multi-stage filtration, impurities in the medicinal liquid are completely separated and remain in the filter screen cover 6, thereby improving the purity and stability of the medicinal liquid. At the same time, by setting a turntable 7 to drive the filter cylinder 4 to rotate, the centrifugal force is used to promote the separation of the medicinal liquid and the medicinal residue, thereby improving the filtration efficiency.

[0039] like Figure 3 As shown, in some embodiments, the turntable 7 includes a conical cover 701 fixedly embedded in the bottom side of the mounting cylinder 1, and a rotating motor 702 is installed on the top wall of the conical cover 701. The output shaft of the rotating motor 702 is connected to the tray 703, and the bottom end of the filter cylinder 4 is embedded in the tray 703. More specifically, when the rotating motor 702 is working, it can drive the tray 703 to rotate, and then drive the filter cylinder 4 to rotate, thereby promoting the separation of the drug residue and the drug liquid through centrifugal force.

[0040] like Figure 3 As shown, in some embodiments, a bull's eye wheel 704 is installed in a circular array on the bottom surface of the tray 703, and the bottom of the bull's eye wheel 704 is slidably connected to the top wall of the conical cover 701. More specifically, the bull's eye wheel 704 can play a supporting role without interfering with the rotation of the tray 703.

[0041] like Figure 3 As shown, in some embodiments, a rubber pad 7031 is embedded in the interior of the tray 703, and anti-slip protrusions 402 are evenly distributed on the filter cartridge 4. More specifically, a layer of rubber pad 7031 is embedded in the interior of the tray 703. The main function of this layer of rubber pad 7031 is to provide cushioning and anti-slip functions. The rubber pad 7031 has good elasticity and wear resistance, and can form a stable contact surface between the filter cartridge 4 and the tray 703. The main function of the anti-slip protrusions 402 is to increase the friction between the filter cartridge 4 and the tray 703, preventing the filter cartridge 4 from sliding or falling off the turntable 7 during rotation.

[0042] like Figure 3As shown, in some embodiments, a retaining ring 2011 is fixedly mounted on the surface of the feed tube 201. The retaining ring 2011 contacts the top of the cross 5. More specifically, when the feed tube 201 is inserted into the filter cartridge 4 and secured, the retaining ring 2011 contacts the top of the cross 5, forming a stable support point. This support point can prevent the filter cartridge 4 from moving upward or shaking due to centrifugal force.

[0043] like Figure 1 As shown, in some embodiments, the locking member 3 includes a hinged rod 301 symmetrically hinged to the side wall of the mounting cylinder 1, and a U-shaped seat 302 is fixed on both sides of the cylinder cover 2. The hinged rod 301 slides through the U-shaped seat 302, and its free end is threadedly connected to a conflicting nut 303, and a rotating plate is fixed to the outer side of the conflicting nut 303. More specifically, when the cylinder cover 2 needs to be fixed, the hinged rod 301 can be rotated so that its upper side is embedded in the U-shaped seat 302, and then the rotating plate is rotated so that the bottom end of the conflicting nut 303 conflicts with the U-shaped seat 302, so that the cylinder cover 2 can be fixed.

[0044] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
