Description

Technical Field

[0001] This utility model relates to the technical field of traditional Chinese medicine extraction equipment, specifically a sieve for a traditional Chinese medicine extraction tank. Background Technology

[0002] After traditional Chinese medicine is extracted in an extraction tank, the residue is filtered through a filtration device to remove dregs and suspended particles, resulting in a clear extract. This reduces the impact of impurities on subsequent concentration or preparation processes, prevents pipe or evaporator blockage, and extends equipment life. For example, a screen-clogging-resistant traditional Chinese medicine extraction tank disclosed in Chinese patent literature (application number: CN202023279256.0) uses a motor-driven striking mechanism to strike the filter screen, allowing dregs to be removed through the discharge port, preventing screen clogging. The screen-striking device is located inside the tank to ensure the device's airtightness; otherwise, the medicinal liquid could corrode the motor, causing damage to the device. Furthermore, the complex structure increases production costs and raises maintenance difficulty and costs. Additionally, the discharge port size of the aforementioned patent is limited, making it impossible to maintain the same width as the filter screen, and the lack of a guide structure for important residue discharge affects the efficiency of removing important residues from the tank.

[0003] Therefore, we propose a sieve for traditional Chinese medicine extraction tanks. Utility Model Content

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The falling Chinese medicine impacts the screen fixing plate, which rotates via a shaft. The left end of the screen fixing plate rotates downward, compressing the spring. The spring only stores and releases energy, but cannot effectively dissipate kinetic energy. After the impact, it will generate continuous reciprocating vibration, causing the screen fixing plate to rotate back and forth. Under the action of the spring, the screen fixing plate vibrates, filtering the Chinese medicine. By absorbing and releasing energy through the spring, the screen fixing plate and the screen vibrate, which can efficiently filter the Chinese medicine, avoid screen clogging, and has a simple structure that is easy to produce and maintain.

[0025] 2. The two sets of first baffles gradually approach the middle of the screen from left to right, forming a channel between the two sets of first baffles for the Chinese medicine to slide through. At the same time, the distance between the right ends of the two sets of first baffles is the same as the width of the front and rear of the discharge port, which reduces the width of the discharge port and facilitates the discharge and collection of Chinese medicine residue.

[0032] Please see Figure 1-4This utility model provides a technical solution: a sieve for a traditional Chinese medicine extraction tank, including a mounting frame 1, a tank body 2, and a sieve 9. The tank body 2 is fixedly installed on the top of the mounting frame 1. A cover plate 3 is located on the top of the tank body 2 and is equipped with fixing bolts 4. A feed pipe 5 is located on the top of the tank body 2. A discharge port 61 is located in the middle of the right side surface of the tank body 2. A receiving plate 6 is fixedly installed on the right side of the tank body 1 and is located at the bottom of the discharge port 61. A mounting shaft 7 is located inside the tank body 1. A sieve fixing plate 8 is installed on the mounting shaft 7. A first baffle 10 is fixedly installed on the sieve fixing plate 8 and has two sets, front and rear. A second baffle 11 is located at the top left end of the sieve fixing plate 8. A support plate 12 is fixedly installed in the middle of the left inner wall of the tank body 1. A spring 13 is fixed. The top of the support plate 12 is installed. After the Chinese medicine enters the tank 1 through the feed pipe 5, the Chinese medicine falls and impacts the screen fixing plate 8. The screen fixing plate 8 rotates through the rotating shaft 7. The left end of the screen fixing plate 8 rotates downward, compressing the spring 13. The spring only stores and releases energy and cannot effectively dissipate kinetic energy. After being impacted, it will generate continuous reciprocating vibration, causing the screen fixing plate 8 to rotate back and forth. Under the action of the spring 13, the screen fixing plate 8 vibrates, filtering the Chinese medicine. The screen fixing plate 8 is set at an angle, and the Chinese medicine slides to the right and is filtered through the screen 9. The Chinese medicine residue slides to the right and is discharged from the tank 1 through the discharge port 61. The Chinese medicine liquid falls into the lower part of the tank 1. The bottom of the tank 1 is equipped with a pipe to discharge the Chinese medicine liquid. The screen fixing plate 8 and the screen 9 vibrate by the absorption and release of energy by the spring 13, which can efficiently filter the Chinese medicine, avoid screen clogging, and has a simple structure that is easy to produce and maintain.

[0033] Reference embodiment: The screen fixing plate 8 is provided with an installation groove 15. The upper half of the installation groove 15 extends in all directions.

The middle of the side of the screen 9 is provided with a first arc-shaped groove 16. A rubber ring 18 is provided between the first arc-shaped groove 16 and the second arc-shaped groove 17. When installing the screen 9, the rubber ring 18 is installed in the second arc-shaped groove 17. The screen 9 is pressed into the installation groove 15 by pressing. The screen 9 and the inner wall of the installation groove 15 cooperate to squeeze the rubber ring 18, thereby quickly installing and fixing the screen 9.

[0034] Reference embodiment: The top of the screen 9 is provided with a column 14, and there are two sets of columns 14. The screen 9 can be quickly disassembled by pulling the screen 9 upward by the two sets of columns. The two sets of first baffles 10 gradually approach the middle of the screen 9 from left to right, forming a channel between the two sets of first baffles 10 for the Chinese medicine to slide through. At the same time, the distance between the right ends of the two sets of first baffles 10 is the same as the front and rear width of the discharge port 61. The Chinese medicine will not pass through the gap between the right end of the screen fixing plate 8 and the inner wall of the tank 1, but will fall to the bottom of the tank 1 and mix with the Chinese medicine liquid. At the same time, the screen 9 and the mounting groove 15 are set according to the direction of the two sets of first baffles 10.

[0035] Reference embodiment: The upper part of the feed pipe 5 is provided with a cone shape to increase the top diameter of the feed pipe 5, which makes it easier to add Chinese medicine into the tank 1.

[0036] Reference embodiment: The inner wall of the tank body 2 is provided with a mounting hole that mates with the mounting shaft 7. The mounting shaft 7 is movably connected to the mounting hole. When the screen fixing plate 8 rotates up and down under the action of the spring, the screen fixing plate 8 rotates through the mounting shaft 7 in the mounting hole.
