Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine technology, specifically a filtration device for the preparation of traditional Chinese medicine. Background Technology

[0002] Drugs that are collected, processed, and prepared according to the guidance of traditional Chinese medicine theory, with explanations of their mechanisms of action and guidance for clinical application, are collectively referred to as Chinese medicine. In short, Chinese medicine refers to substances used to prevent, treat, and diagnose diseases and have rehabilitation and health care effects under the guidance of traditional Chinese medicine theory. Chinese medicine mainly comes from natural medicines and their processed products, including plant medicines, animal medicines, mineral medicines, and some chemical and biological products. Because Chinese medicine is mostly composed of plant medicines, there is a saying that "all medicines are based on herbs".

[0003] In the process of utilizing traditional Chinese medicine, the decoction method is usually adopted, so that the medicinal effects are absorbed orally after being dissolved in water. After decoction, in order to facilitate smooth oral administration, it is necessary to separate the dregs and the liquid. The existing separation method uses gauze for solid-liquid separation, which is slow. The squeezing method causes a small amount of dregs to be squeezed out, affecting the taste of the liquid. In order to quickly and efficiently separate the liquid and dregs, we propose a filtration device for the preparation of traditional Chinese medicine. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filtration device for traditional Chinese medicine preparation, which solves the problem of slow separation speed of medicinal residue and liquid mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a filtration device for the preparation of traditional Chinese medicine, comprising a filter box, a guide pipe fixedly connected to the bottom end of the filter box, a liquid collection box fixedly supported at the rear top end of the guide pipe, a pressure box supported on the top surface of the liquid collection box, a telescopic column fixedly installed on the top surface of the pressure box, a movable plug fixedly connected to the bottom end of the telescopic column, and a one-way exhaust valve supported on the top surface of the liquid collection box.

[0006] Optionally, the inner cavity of the filter box is fixedly supported by a support plate, the inner cavity of the filter box is filled with filter gauze, and the top of the filter box is movably fitted with a cover.

[0007] Optionally, a limiting sleeve is fixedly installed in the inner cavity of the liquid collection tank, the top end of the guide tube extends into the inner cavity of the liquid collection tank, the limiting sleeve is fixedly fitted on the outside of the guide tube, and a sealing ball is provided inside the limiting sleeve.

[0008] Optionally, a flow guide block is fixedly supported on the bottom surface of the inner cavity of the liquid collection tank. The flow guide block is fixedly fitted on the outside of the limiting sleeve, and a sealing ball is provided in the inner cavity of the limiting sleeve.

[0009] Optionally, the diameter of the sealing ball is larger than the inner diameter of the top of the guide tube, and the external movable sleeve of the liquid collection tank is equipped with a drain sleeve.

[0010] Optionally, the movable plug is movably fitted into the inner cavity of the pressure box, and the inner cavity of the pressure box and the inner cavity of the liquid collection box are interconnected.

[0011] This utility model provides a filtration device for the preparation of traditional Chinese medicine, which has the following beneficial effects:

[0012] 1. This filtration device for traditional Chinese medicine preparation, through the arrangement of a filter box, a guide pipe, and a collection tank, can separate the medicinal liquid and the dregs. The filter gauze can hold the mixture of medicinal liquid and dregs, while the medicinal liquid divides the upper and lower spaces of the inner cavity of the filter box. During the slow rise of the movable plug controlled by the telescopic column at the top of the pressure box, the air pressure in the lower part of the filter box and the inner cavity of the guide pipe and the collection tank can be reduced, thereby increasing the filtration speed.

[0013] 2. This filter device for preparing traditional Chinese medicine uses a height difference between the top and bottom of the guide tube to assist the flow of the medicine liquid through the guide tube. A limiting sleeve is installed inside the collection tank and fitted onto the top of the guide tube. The sealing ball is positioned inside the limiting sleeve, which can seal the collection tank and prevent backflow of the liquid. At the same time, the cooperation of the one-way exhaust valve can realize the reset of the movable plug. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1 to 4This utility model provides a technical solution: a filtration device for traditional Chinese medicine preparation, including a filter box 1. A guide pipe 2 is fixedly connected to the bottom of the filter box 1. The guide pipe 2 connects the filter box 1 and a collection tank 3. The front height of the guide pipe 2 is higher than its rear height, which helps to continuously guide the medicinal liquid through the guide pipe 2 into the inner cavity of the collection tank 3, ensuring stable flow. The collection tank 3 is fixedly supported at the rear top of the guide pipe 2. The inner cavity of the filter box 1 separates the medicinal liquid. The collection tank 3 works with the guide pipe 2 to collect the medicinal liquid. A pressure tank 7 is supported on the top surface of the collection tank 3. A telescopic column 8 is fixedly installed on the top surface of the pressure tank 7. A movable plug 9 is fixedly connected to the bottom end. The outer side of the movable plug 9 is in contact with the inner wall of the telescopic column 8. The movable plug 9 is made of sealing rubber. The telescopic column 8 controls the rise of the movable plug 9, which can effectively reduce the air pressure inside the liquid collection tank 3. The top surface of the liquid collection tank 3 is supported by a one-way exhaust valve 10. The one-way exhaust valve 10 is set to exhaust air and ensure the stability of the air pressure inside the liquid collection tank 3. After the movable plug 9 is located at the top of the inner cavity of the pressure tank 7, the sealing ball 5 will re-seal the top surface of the guide pipe 2 under the action of gravity. Then, the output shaft of the telescopic column 8 is controlled to push the movable plug 9 downward, so that the air per unit volume inside the pressure tank 7 is discharged to the outside of the liquid collection tank 3 through the one-way exhaust valve 10.

[0021] The inner cavity of the filter box 1 is fixedly supported by a support plate 12. The inner cavity of the filter box 1 contains filter gauze 13. The top of the filter box 1 is movably fitted with a cover 14. The support plate 12 can support the filter gauze 13. The filter gauze 13 achieves solid-liquid separation filtration. The cover 14, together with the filter box 1, forms a sealed space to assist filtration.

[0022] A limiting sleeve 4 is fixedly installed in the inner cavity of the collection tank 3. The top end of the guide tube 2 extends into the inner cavity of the collection tank 3. The limiting sleeve 4 is fixedly installed on the outside of the guide tube 2. A sealing ball 5 is provided inside the limiting sleeve 4. The cooperation between the limiting sleeve 4 and the sealing ball 5 can complete the sealing of the top end of the guide tube 2 to prevent the backflow of the medicine.

[0023] The bottom surface of the inner cavity of the collection tank 3 is fixedly supported by a guide block 6. The guide block 6 is fixedly fitted on the outside of the limiting sleeve 4. The inner cavity of the limiting sleeve 4 is provided with a blocking ball 5. The guide block 6 can guide the liquid to the drain sleeve 11 for discharge.

[0024] The diameter of the sealing ball 5 is greater than the inner diameter of the top of the guide tube 2, and the external movable sleeve of the collection tank 3 is fitted with a drain sleeve 11.

[0025] The movable plug 9 is installed inside the pressure box 7, and the inner cavity of the pressure box 7 and the inner cavity of the liquid collection box 3 are connected to each other.

[0026] In summary, when using this filtration device for traditional Chinese medicine preparation, first open the cover 14, lay the filter gauze 13 inside the filter box 1, and support the filter gauze 13 with the support plate 12. Then, pour the boiled and cooled mixture of medicinal liquid and dregs into the filter box 1. The filter gauze 13 holds the raw material to be filtered, and the medicinal liquid will help to divide the internal space of the filter box 1. Then, seal the top of the filter box 1 with the cover 14. First, close the drain sleeve 11 to keep the internal cavity of the collection box 3 closed. Then, control the output shaft of the telescopic column 8 to move upward. The output shaft of the telescopic column 8 drives the movable plug 9 to move upward slowly, thereby increasing the air in the internal cavity of the collection box 3 and reducing the air pressure in the internal cavity of the collection box 3. Then, the pressure in the internal cavity of the collection box 3 and the internal cavity of the guide pipe 2 is used to... The force difference pushes the sealing ball 5 upward, connecting the inner cavity of the guide tube 2 and the inner cavity of the collection tank 3. At the same time, a pressure difference is formed in the inner cavity of the filter box 1. The pressure difference helps the liquid to quickly pass through the collection tank 3 and fall into the inner cavity of the guide tube 2. After the movable plug 9 is located at the top of the inner cavity of the pressure box 7, the sealing ball 5 will re-seal the top surface of the guide tube 2 under the action of gravity. Then, the output shaft of the telescopic column 8 is controlled to push the movable plug 9 downward, so that the unit volume of air in the inner cavity of the pressure box 7 is discharged to the outside of the collection tank 3 through the one-way exhaust valve 10. The extraction of the liquid is completed in sequence. After the liquid and residue are separated, the drain sleeve 11 is opened. The liquid in the inner cavity of the collection tank 3 will be guided by the guide block 6 to move towards the outside of the inner cavity of the collection tank 3, and then be discharged through the drain sleeve 11.
