Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filtration system for tea extraction. Background Technology

[0002] During the extraction process, tea leaves are soaked and stirred, breaking them down and releasing their components. After extraction, a significant amount of tea leaves remain in the extract. If these residues are not removed, they will affect the quality of the extract and its subsequent use.

[0003] Therefore, the extract needs to be filtered. Current filtration devices mainly use filter plates to filter the extract. Filtration is simple and effective. However, as the filtration time increases, a large amount of tea leaves will remain on the filter plate, affecting the filtration speed. Therefore, the tea leaves on the filter plate need to be cleaned regularly, which is not only troublesome but also affects the filtration process. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a filtration system for tea extraction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tea extraction filtration system, including a base plate, a support plate fixed to one side of the top outer wall of the base plate, and a conveyor belt rotatably mounted on one side outer wall of the support plate. Multiple equally spaced scraping components are fixed to the outer wall of the conveyor belt, and a filter plate is installed on one side outer wall of the conveyor belt. An air blowing component is installed at one end of the top outer wall of the support plate, and a liquid inlet pipe is installed at the other end of the top outer wall of the support plate. A collection component is fixed to one side outer wall of the support plate.

[0006] By adopting the above technical solution, the extract can be introduced into the inlet pipe, and the extract flows out from the inlet pipe and is filtered through the filter plate. The filter plate filters out the tea leaves in the extract. During the filtration process, the scraping component can be rotated by the conveyor belt. The scraping component can scrape away the tea leaves filtered down from the top of the filter plate during the rotation, ensuring the filtration speed and filtration effect of the filter plate. There is no need for manual cleaning of the filter plate, which is more convenient. The scraped tea leaves will fall into the collection component for collection. At the same time, when the scraping component moves under the air blowing component, the air blowing downwards from the air blowing component can blow off the tea leaves that are still attached to the scraping component.

[0007] Furthermore, the scraping assembly includes a fixed plate, a groove on one outer wall of the fixed plate, an elastic component disposed on the inner wall of the groove, and a scraper fixed to the outer wall of the elastic component.

[0008] By adopting the above technical solution, the fixed plate can move with the rotation of the conveyor belt. During the movement, it passes over the filter plate and the scraper contacts the filter plate, which can scrape away the tea leaves filtered down from the top of the filter plate. The elastic component can be set to press the scraper lightly on the filter plate to improve the tea leaf scraping effect.

[0009] Furthermore, the elastic component includes a fixed rod, a spring sleeved on one end of the fixed rod, and a slider sleeved on the other end of the fixed rod.

[0010] By adopting the above technical solution, the scraper contacts the filter plate, causing the slider to rise and compress the spring. The spring's reaction force then gently presses the scraper onto the filter plate.

[0011] Furthermore, the air blowing assembly includes a main pipe, a fan installed at one end of the main pipe, and multiple equally spaced branch pipes connected to the inner wall at the bottom of the main pipe.

[0012] By adopting the above technical solution, the fan can blow airflow into the main pipe, and the airflow can be blown out from the bottom of the branch pipe.

[0013] Furthermore, the collection assembly includes a suspension plate, a receiving hopper installed on one end of the top outer wall of the suspension plate, and a collection box located below the receiving hopper.

[0014] By adopting the above technical solution, the tea leaves scraped off by the scraper can pass through the receiving hopper and eventually fall into the collection box.

[0015] Furthermore, a connecting bucket is fixed to one side of the outer wall of the support plate, and a container is provided below the connecting bucket.

[0016] By adopting the above technical solution, it is convenient to receive the filtered extract.

[0017] Furthermore, both ends of the filter plate have a beveled structure.

[0018] By adopting the above technical solution, the scraper can be made to first contact the inclined surface and slowly rise during the movement process, driving the slider to rise and squeeze the spring.

[0019] Furthermore, the top outer wall of the slider has a through hole, and the slider is sleeved on the fixed rod.

[0020] By adopting the above technical solution, the slider can slide on the fixed rod.

[0021] In summary, this utility model has the following beneficial effects:

[0022] In this application, a filter plate can be used to filter tea leaves from the extract. During the filtration process, a conveyor belt can drive the scraping component to rotate. The scraping component can scrape away the tea leaves filtered down from the top of the filter plate during the rotation, ensuring the filtration speed and filtration effect of the filter plate. There is no need for manual cleaning of the filter plate, which is more convenient. The scraped tea leaves will fall into the collection component and be collected. At the same time, when the scraping component moves below the blowing component, the airflow blown down by the blowing component can blow away the tea leaves that are still attached to the scraping component.

[0030] like Figure 1-5As shown in the embodiment of this application, a tea extraction filtration system is disclosed, including a base plate 1. A support plate 2 is fixed to one side of the top outer wall of the base plate 1, and a conveyor belt 3 is rotatably mounted on one side of the outer wall of the support plate 2. A plurality of equally spaced scraping components 4 are fixed to the outer wall of the conveyor belt 3. Each scraping component 4 includes a fixed plate 401, a groove 402 on one side of the outer wall of the fixed plate 401, an elastic component 403 disposed on the inner wall of the groove 402, and a scraper 404 fixed to the outer wall of the elastic component 403. The fixed plate 401 can move with the rotation of the conveyor belt 3. During the movement, it passes over the filter plate 5. The scraper 404 contacts the filter plate 5 and can scrape away the tea leaves filtered down from the top of the filter plate 5. The elastic component 403 can lightly press the scraper 404 onto the filter plate 5 to improve the scraping effect. The elastic component 403 includes a fixed rod 403-1, a spring 403-2 sleeved on one end of the fixed rod 403-1, and a slider 403-3 sleeved on the other end of the fixed rod 403-1. When the scraper 404 contacts the filter plate 5, it drives the slider 403-3 to rise and compress the spring 403-2. The reaction force of the spring 403-2 is used to lightly press the scraper 404 onto the filter plate 5.

[0031] Furthermore, a filter plate 5 is installed on one side of the outer wall of the conveyor belt 3, and an air blowing assembly 6 is installed on one end of the top outer wall of the support plate 2. The air blowing assembly 6 includes a main pipe 601, a fan 602 installed at one end of the main pipe 601, and multiple equally spaced branch pipes 603 connected to the bottom inner wall of the main pipe 601. The fan 602 can blow air into the main pipe 601, and the air is blown out from the bottom of the branch pipes 603.

[0032] Furthermore, an inlet pipe 7 is installed at the other end of the top outer wall of the support plate 2, and a collection assembly 8 is fixed on one side of the outer wall of the support plate 2. The collection assembly 8 includes a suspension plate 801, a receiving hopper 802 installed at one end of the top outer wall of the suspension plate 801, and a collection box 803 located below the receiving hopper 802. The tea leaves scraped off by the scraper 404 can pass through the receiving hopper 802 and eventually fall into the collection box 803. The extract can be introduced into the inlet pipe 7, and the extract flows out from the inlet pipe 7 and is filtered by the filter plate 5. The filter plate 5 is used to filter the extract. The tea leaves are filtered down. During the filtration process, the conveyor belt 3 drives the scraper assembly 4 to rotate. The scraper assembly 4 can scrape away the tea leaves filtered down from the top of the filter plate 5 during the rotation, ensuring the filtration speed and filtration effect of the filter plate 5. There is no need for manual cleaning of the filter plate 5, which is more convenient. The scraped tea leaves will fall to the collection assembly 8 for collection. At the same time, when the scraper assembly 4 moves to the bottom of the air blowing assembly 6, the air blowing downwards from the air blowing assembly 6 can blow away the tea leaves that are still attached to the scraper assembly 4.

[0033] The working principle of the tea extraction filtration system in this embodiment is as follows: The extract is introduced into the inlet pipe 7 and flows out through the inlet pipe 7, passing through the filter plate 5 for filtration. The filter plate 5 filters out the tea leaves from the extract. During the filtration process, the conveyor belt 3 can be activated, and the fixed plate 401 can move with the rotation of the conveyor belt 3. During this movement, as it passes above the filter plate 5, the scraper 404 contacts the filter plate 5, scraping away the tea leaves filtered down from the top of the filter plate 5. The contact between the scraper 404 and the filter plate 5 causes the slider 403-3 to rise and compress the spring 403. -2. Utilizing the reaction force of spring 403-2, scraper 404 is lightly pressed onto filter plate 5 to improve the scraping effect of tea leaves, ensuring the filtration speed and effect of filter plate 5. No manual cleaning of filter plate 5 is required, making it more convenient. The tea leaves scraped off by scraper 404 can pass through receiving hopper 802 and finally fall into collection box 803. Fan 602 can blow air into main pipe 601, and the airflow blows out from the bottom of branch pipe 603. When scraper 404 moves to below branch pipe 603, the airflow blown downward from branch pipe 603 can blow off the tea leaves that are still attached to scraper 404.
