[0040] Traditional Chinese medicines generally need to extract effective components through methods such as steaming, boiling, soaking, etc., so solid-liquid separation is required to separate the medicinal residues from the medicinal liquid. In the related prior art, the filtering devices for extracting traditional Chinese medicines mainly adopt ordinary funnel filtration. Although combined with the design of spiral stirring, due to the funnel filtration method, the medicinal residues are too concentrated, so the filtration effect is not ideal, and the cleaning is difficult, and it is difficult to clean and discharge the medicinal residues.

[0041] In a first aspect, the present utility model provides a traditional Chinese medicine filtering device, which can take into account both filtration and cleaning, and solve the problems of unsatisfactory filtration effect and difficult cleaning.

[0042] In a second aspect, the present utility model provides a traditional Chinese medicine filtering method using the above traditional Chinese medicine filtering device.

[0043] Referring to Figures 1 to 3 , a traditional Chinese medicine filtering device according to an embodiment of the first aspect of the present utility model includes a device main body 100 and a filtering rack 200. Specifically, a filtering cavity 1011 is provided inside the device main body 100, and a liquid inlet pipe 1012 and a cleaning pipe 1021 communicating with the filtering cavity 1011 are provided at the upper end of the device main body 100, and a liquid outlet pipe 1014 and a sewage discharge pipe 1013 communicating with the filtering cavity 1011 are provided at the lower end of the device main body 100, and the sewage discharge pipe 1013 is higher than the liquid outlet pipe 1014. The filtering rack 200 is arranged in the filtering cavity 1011, and the filtering rack 200 includes a filter mesh rack 201 and a filtering chassis 202. The filtering chassis 202 is horizontally arranged in the filtering cavity 1011 and is hermetically arranged between the inner wall of the filtering cavity 1011. The filtering chassis 202 is located between the sewage discharge pipe 1013 and the liquid outlet pipe 1014. The filter mesh rack 201 is in a conical structure, and the lower end of the filter mesh rack 201 is connected to the periphery of the filtering chassis 202. It can be understood that the lower end of the filter mesh rack 201 in this embodiment is opened to be close to the inner wall of the filtering cavity 1011 to form a conical filtering surface. Since the sewage discharge pipe 1013 is higher than the liquid outlet pipe 1014, if the filtering rack 200 is used as the boundary, the liquid inlet pipe 1012, the cleaning pipe 1021 and the sewage discharge pipe 1013 are all on the same side of the filtering rack 200, and the liquid outlet pipe 1014 is on the other side of the filtering rack 200.

[0044] It can be understood that during the filtration operation, the cleaning pipe 1021 and the sewage discharge pipe 1013 are closed, and the liquid medicine is fed in from the liquid inlet pipe 1012 and discharged from the liquid outlet pipe 1014. During the cleaning operation, the cleaning water is fed in from the cleaning pipe 1021, the liquid inlet pipe 1012 is closed, and the sewage after cleaning is discharged from the sewage discharge pipe 1013 and the liquid outlet pipe 1014.

[0045] In the traditional Chinese medicine filtering device of the present utility model, by arranging a filter rack 200 in the filtering cavity 1011, only the liquid medicine to be filtered needs to be fed in from the liquid inlet pipe 1012, and then it can be filtered through the conical filter mesh rack 201. Since the filter mesh rack 201 is of a conical structure, the impact force and gravity during the feeding of the liquid medicine can be utilized to quickly filter the liquid medicine. Further, a filter bottom plate 202 can be designed to further filter the liquid medicine through the filter bottom plate 202, improving the filtering effect. The filtered liquid medicine can be discharged from the liquid outlet pipe 1014. During cleaning, only the cleaning water needs to be discharged from the cleaning pipe 1021, and then the impact force and gravity of the cleaning water can be utilized to wash the medicinal residue downward along the conical surface of the filter mesh rack 201 and discharge it from the sewage discharge pipe 1013, making the cleaning convenient. Therefore, the traditional Chinese medicine filtering device of the present utility model can not only ensure the filtering efficiency but also be convenient for cleaning, effectively solving the deficiencies of the traditional structure.

[0046] Refer to Figure 1 and Figure 2 In some embodiments of the present utility model, a gap is maintained between the filter bottom plate 202 and the bottom of the filtering cavity 1011. The filtering cavity 1011 is separated by the filter bottom plate 202 to form an upper chamber and a lower chamber. Obviously, the sewage discharge pipe 1013 is connected to the upper chamber, and the liquid outlet pipe 1014 is connected to the bottom of the lower chamber. With the structural arrangement of this embodiment, the lower chamber can be utilized to store the filtered liquid medicine, avoiding the situation where the discharge speed of the liquid outlet pipe 1014 is lower than the filtering speed of the filter rack 200, resulting in the inability to timely discharge the filtered liquid medicine and affecting the filtering efficiency. By setting the lower chamber, buffering of the filtered liquid medicine can be achieved, improving the discharge uniformity of the liquid outlet pipe 1014.

[0047] Refer to Figure 1 and Figure 2, in some embodiments of the present utility model, the device main body 100 includes a tank body 101 and a cover body 102. A filtering cavity 1011 is arranged inside the tank body 101, and preferably a cavity with a circular cross-sectional profile is adopted. Support feet 1015 are arranged at the bottom of the tank body 101. A sewage discharge pipe 1013 and a liquid inlet pipe 1012 are both connected to the side wall of the tank body 101, while a liquid outlet pipe 1014 is connected to the bottom of the tank body 101. By arranging the support feet 1015, the tank body 101 can be lifted off the ground, enabling the liquid outlet pipe 1014 to be connected to the bottom of the tank body 101, which is conducive to completely emptying the liquid medicine or cleaning water. The cover body 102 is detachably connected to the top of the tank body 101 for covering the filtering cavity 1011. A cleaning pipe 1021 is connected to the center position at the upper end of the cover body 102. Since the filter mesh frame 201 is of a conical structure, arranging the cleaning pipe 1021 at the center position at the upper end of the cover body 102 helps to align with the top end of the filter mesh frame 201. When cleaning water is fed in, the filter mesh frame 201 can be evenly flushed, improving the cleaning effect. The filtering cavity 1011 is arranged as a cavity with a circular cross-sectional profile. Correspondingly, the filtering bottom plate 202 is also circular, which is conducive to the sealing design and also facilitates the loading and unloading of the filter frame 200.

[0048] Referring to Figure 1 and Figure 2 , in order to realize the installation of the filter frame 200, in some embodiments of the present utility model, the filter frame 200 is provided with an installation rod 203. The filter mesh frame 201 and the filtering bottom plate 202 are both installed on the installation rod 203, and the upper end of the installation rod 203 is detachably connected to the cover body 102. In this way, when the cover body 102 is installed, the filter frame 200 can be kept inside the filtering cavity 1011. Since the periphery of the filtering bottom plate 202 abuts against the inner wall of the filtering cavity 1011, the structural stability of the filter frame 200 is relatively high, which not only realizes the simplified design of the structure but also ensures the stability and structural strength of the structure during operation.

[0049] Referring to Figures 4 to 6, in some embodiments of the present utility model, the filter mesh frame 201 includes a plurality of longitudinal support rods 2011 and several support rings 2012. Specifically, the upper ends of the longitudinal support rods 2011 are connected together, and the lower ends are evenly connected to the edge of the filter chassis 202 to form a conical structure. And along the circumferential direction, the distance between any two adjacent longitudinal support rods 2011 remains the same, so as to ensure uniform filtering effect and avoid local blockage. The support rings 2012 connect all the longitudinal support rods 2011 along the circumferential direction, thereby improving the structural strength between the longitudinal support rods 2011 and the overall stiffness. And when there are multiple support rings 2012, the multiple support rings 2012 are distributed vertically, so as to reinforce the filter mesh frame 201 along the length direction of the longitudinal support rods 2011. It can be understood that since the multiple longitudinal support rods 2011 are distributed in a conical shape, the outer diameter of the contour formed by the longitudinal support rods 2011 gradually increases from top to bottom. When there are multiple support rings 2012, the outer diameter sizes of the support rings 2012 are different to meet the installation requirements at different positions.

[0050] Since the bottom of the filter mesh frame 201 is connected to the filter chassis 202, the support rings 2012 can be provided only at the middle position in the length direction of the longitudinal support rods 2011.

[0051] Specifically, the support rings 2012 can be directly welded to the longitudinal support rods 2011, or can be connected and fixed by means of clamping or splicing.

[0052] Refer to Figure 4 , in some embodiments of the present utility model, the filter mesh frame 201 further includes a positioning ring 2013. The inner diameter of the positioning ring 2013 is adapted to the rod diameter of the mounting rod 203. The upper ends of the longitudinal support rods 2011 are connected to the positioning ring 2013, and the positioning ring 2013 is sleeved on the mounting rod 203. It can be understood that the positioning ring 2013 and the mounting rod 203 in this embodiment may not be fixed, only sleeved, so that the filter mesh frame 201 and the filter chassis 202 can be removed from the mounting rod 203 for cleaning and maintenance. And setting the positioning ring 2013 for the installation of the longitudinal support rods 2011 is beneficial to improving the installation accuracy and convenience of the longitudinal support rods 2011.

[0053] Refer to Figures 4 to 6 , in some embodiments of the present utility model, a threaded hole is provided at the center of the filter chassis 202, and the mounting rod 203 is screwed into the threaded hole. By using the threaded hole to connect the mounting rod 203 and combining with the design of the positioning ring 2013, the filter mesh frame 201 and the filter chassis 202 can be disassembled from the mounting rod 203, with stronger flexibility, which can not only reduce the difficulty of equipment production and assembly, but also facilitate disassembly and maintenance.

[0054] Reference Figures 1 to 4 , in some embodiments of the present utility model, the mounting rod 203 has a mounting section extending above the filter mesh frame 201. The mounting section is provided with an external thread, and the upper end of the mounting section is threadedly connected to the cover body 102, so that it can be quickly disassembled during the maintenance stage.

[0055] Reference Figure 4 , in some embodiments of the present utility model, the filter chassis 202 includes a central disk area 2021 and an outer edge area 2022 from the inside to the outside. The central disk area 2021 is provided with a filtering structure 2023, such as filtering holes, while the outer edge area 2022 is distributed on the circumferential side edge of the central disk area 2021. Since the filtering structure 2023 is only distributed in the central disk area 2021, the outer edge area 2022 is a closed area without holes. On this basis, the lower end of the filter mesh frame 201 is connected to the demarcation line formed by the central disk area 2021 and the outer edge area 2022, so that the central disk area 2021 is covered by the filter mesh frame 201, and the outer edge area 2022 is located outside the filter mesh frame 201. By adopting the structural arrangement of this embodiment, the outer edge area 2022 can be used to fit with the inner wall of the filtering device, so that the liquid medicine can only be discharged from the liquid outlet pipe 1014 after passing through the filter mesh frame 201 and the filter chassis 202, which is beneficial to improving the filtering effect.

[0056] Further, reference Figure 2 , the filter frame 200 further includes a first filter mesh cloth 300. The first filter mesh cloth 300 is laid on the filter mesh frame 201, and the lower end of the first filter mesh cloth 300 extends to the outer edge area 2022. In this way, the liquid medicine can only be discharged after passing through the first filter mesh cloth 300, which can prevent the liquid medicine from passing through the circumferential side of the filter mesh frame 201.

[0057] Further, reference Figure 2 , the filter frame 200 further includes a second filter mesh cloth 400. The second filter mesh cloth 400 is sleeved under the filter chassis 202 and extends from the circumferential side of the filter chassis 202 to the upper end surface of the outer edge area 2022. The second filter mesh cloth 400 can be used to further improve the filtering effect, and it can be installed through the outer edge area 2022 to avoid the existence of loopholes and improve the filtering effect.

[0058] Further, a sealing ring is provided at the edge position of the filter chassis 202, and the sealing ring abuts against the inner wall of the filter chamber 1011. By using the sealing ring to abut against the inner wall of the filter chamber 1011, the filtering effect can be further ensured, and it can prevent the liquid medicine from passing through the circumferential side and affecting the filtering effect.

[0059] It can be understood that the first filter cloth 300 can adopt a conical design, so as to be laid on the outer surface of the filter mesh frame 201, and the lower end is kept laid on the outer edge area 2022. The second filter cloth 400 is sleeved on the filter chassis 202 from below the filter chassis 202, and the edge of the second filter cloth 400 is covered on the upper surface of the outer edge area 2022. During installation, the first filter cloth 300 is kept covering the upper surface of the second filter cloth 400 to avoid gaps. Then, a sealing ring is used to sleeve the edge of the filter chassis 202 to press the first filter cloth 300 and the second filter cloth 400, so as to ensure the sealing performance at the edge position and eliminate leakage points.

[0060] The present utility model further provides a traditional Chinese medicine filtering method, which is applied to the above-mentioned traditional Chinese medicine filtering device, and includes:

[0061] Filtering operation: Close the cleaning pipe 1021 and the sewage discharge pipe 1013, send the medicinal liquid into the filtering chamber 1011 through the liquid inlet pipe 1012, and discharge the filtered medicinal liquid through the liquid outlet pipe 1014;

[0062] Cleaning operation: After the working set time or after the medicinal liquid filtering is completed, close the liquid inlet pipe 1012, open the sewage discharge pipe 1013, send cleaning water into the filtering chamber 1011 through the cleaning pipe 1021 for flushing, discharge the mixture of the medicinal residue and the cleaning water washed out through the sewage discharge pipe 1013, and discharge the cleaning water through the liquid outlet pipe 1014.

[0063] Furthermore, the cleaning operation further includes removing the cover body 102, taking out the filter frame 200, replacing the first filter cloth 300 and the second filter cloth 400, and then reinstalling them on the tank body 101 for filtering operation.

[0064] In the traditional Chinese medicine filtering method of the present utility model, by applying the aforementioned traditional Chinese medicine filtering device, since the filter mesh frame 201 is a conical structure, the impact force and gravity during the feeding of the medicinal liquid can be utilized to quickly filter the medicinal liquid. And the filter chassis 202 can be further designed to further filter by using the filter chassis 202, improving the filtering effect. The filtered medicinal liquid can be discharged from the liquid outlet pipe 1014. During cleaning, only need to drain the cleaning water from the cleaning pipe 1021, then the impact force and gravity of the cleaning water can be utilized to wash the medicinal residue downward along the conical surface of the filter mesh frame 201 and discharge it from the sewage discharge pipe 1013. The cleaning is convenient, which can not only ensure the filtering efficiency but also facilitate cleaning, effectively improving the production efficiency and solving the deficiencies of the traditional structure.

[0065] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art. In addition, the embodiments of the present utility model and the features in the embodiments can be combined with each other without conflict.
