Description

Technical Field

[0001] This utility model relates to the field of plant beverage filtration technology, specifically to a high-efficiency filtration system for plant beverage production. Background Technology

[0002] Plant-based beverages refer to beverage products made from plants or plant extracts through processing or fermentation. They represent the third generation of beverages after carbonated and fruit / vegetable drinks. Due to their inherent characteristics of being "natural, green, nutritious, and healthy," plant-based beverages align with the trends and development of the beverage market and are increasingly favored by consumers. Traditional plant-based beverage production involves pressing plants to extract their juice. This juice may contain a significant amount of plant fiber and other impurities, resulting in a less desirable taste. To achieve a better-tasting beverage with fewer impurities and higher purity, filtration is necessary. However, in actual production, issues such as the viscosity of the juice or the varying sizes of impurity particles often cause clogging of the filter components. This necessitates frequent cleaning of the filter, reducing production efficiency, posing a risk of juice contamination, and increasing worker workload and production costs. Furthermore, current filtration systems often suffer from poor filtration efficiency and contain numerous impurities, failing to adequately meet consumer needs. Therefore, it is an objective need to develop a high-efficiency filtration system for plant beverage production that is not prone to clogging, can be automatically cleaned online, and has a good filtration effect. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency filtration system for plant beverage production that is not easily clogged, can be automatically cleaned online, and has a good filtration effect.

[0004] The purpose of this utility model is achieved as follows: It includes a tank and an inlet located at the top of the tank. The internal space of the tank is divided into a filtration chamber and a sludge storage chamber from top to bottom by a partition. Multiple cylindrical filter screens are concentrically arranged from the outside to the inside of the filtration chamber. The upper ends of the filter screens are sealed, and the lower ends are fixedly connected to the partition. A motor is installed at the top of the tank. The output shaft of the motor extends into the filtration chamber and is connected to a vertical shaft. Multiple connecting rods are arranged from top to bottom on the vertical shaft. Brushes are installed at the ends of the connecting rods, with the bristles in close contact with the outer surface of the filter screen. A scraper is installed at the lower end of the brush, with the lower end of the scraper abutting against the upper surface of the partition. A sludge storage pipe is installed on the partition in the annular area between the tank and the outermost filter screen, and between two adjacent filter screens. The sludge storage pipe is located in the sludge storage chamber, and a valve is installed at the lower end of the sludge storage pipe. A drain pipe is installed on the partition inside the innermost filter screen, with its end bent and extending to the outside of the sludge storage chamber.

[0005] Furthermore, the filter screen is provided with several inwardly recessed annular grooves at intervals from top to bottom.

[0006] Furthermore, a backwash pipe is installed on the drain pipe.

[0007] Furthermore, the mesh diameter of the multiple filters gradually decreases from the outside to the inside.

[0008] Furthermore, a return pipe is installed at the top of the sludge storage chamber, and the end of the return pipe is connected to the filter chamber. A return pump is installed on the return pipe.

[0009] Furthermore, a cone is set in the annular space above each scraper. The cone has a structure with a larger upper end and a smaller lower end. The upper end of the cone is fixedly connected to the corresponding filter screen. The upper end of the outermost cone is fixedly connected to the tank. The lower end of the cone is suspended in the air, and a gap is left between the lower end of the cone and the corresponding filter screen.

[0010] When this invention is in operation, the plant-based beverage enters the tank through the inlet and passes through various cylindrical filters from the outside to the inside, thus filtering the beverage sequentially. The purer beverage enters the innermost filter and is then discharged through the drain pipe. During this process, the motor is started, which drives the vertical shaft to rotate. The vertical shaft then drives the connecting rod to rotate, which in turn drives the brush and scraper to rotate. The bristles of the brush remove plant fibers and other impurities adhering to the filter screen. The impurities fall to the bottom of the filter chamber and are then carried by the scraper into the sludge storage pipe. When the impurities accumulated in the sludge storage pipe reach a certain level, the valve is opened, and the impurities fall into the sludge storage chamber for storage. The valve is then closed, allowing the plant fibers and other impurities in the plant-based beverage to be stored in the sludge storage chamber for periodic discharge. In the aforementioned operation, this invention uses a rotating brush to clean the surface of the filter screen, preventing clogging and effectively maintaining its filtration efficiency over long-term use. Secondly, it employs a multi-layer filter structure, performing multiple layers of filtration on the plant-based beverage, ensuring effective filtration. Furthermore, during the filtration process, a scraper removes plant fibers and other impurities that fall to the bottom and pushes them into a storage tank for temporary storage. The valve is periodically opened based on the amount of impurities stored in the tank to promptly discharge these impurities, and then closed again. The impurities then fall into the storage chamber and are periodically discharged. The entire cleaning process for plant fibers and other impurities is automated, eliminating the need to shut down the filtration system. This online cleaning eliminates the need for frequent cleaning of the filter components, allowing the entire system to operate normally for extended periods. This improves the production efficiency of plant-based beverages, avoids the risk of contamination caused by manual cleaning of filter components, and reduces worker workload and production costs. In summary, this invention has the advantages of being less prone to clogging, automatically cleaning online, and providing excellent filtration results. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings, but this description is not intended to limit the present invention in any way. Any changes or improvements made based on the present invention shall fall within the protection scope of the present invention.

[0014] like Figure 1 As shown, this utility model includes a tank body 1 and a feed inlet 2 located at the top of the tank body 1. The internal space of the tank body 1 is divided into a filter chamber 4 and a sludge storage chamber 5 from top to bottom by a partition 3. Multiple cylindrical filter screens 6 are arranged concentrically from the outside to the inside of the filter chamber 4. The upper end of the filter screens 6 is sealed, and the lower end is fixedly connected to the partition 3. A motor 7 is installed on the top of the tank body 1. The motor 7 is an existing device, and its power and speed parameters can be determined according to the actual situation. The output shaft of the motor 7 extends into the filter chamber 4 and is connected to a vertical shaft 8. Multiple cylindrical filter screens 6 are arranged from top to bottom on the vertical shaft 8. A connecting rod is provided with a brush 9 at its end. The bristles of the brush 9 are in close contact with the outer surface of the filter screen 6. A scraper 10 is provided at the lower end of the brush 9. The lower end of the scraper 10 abuts against the upper surface of the partition 3. A sludge storage pipe 11 is provided on the partition 3 in the annular area between the tank 1 and the outermost filter screen 6 and between two adjacent filter screens 6. The sludge storage pipe 11 is located in the sludge storage chamber 5. A valve is provided at the lower end of the sludge storage pipe 11. A drain pipe 12 is provided on the partition 3 inside the innermost filter screen 6. The end of the drain pipe 12 is bent and extends to the outside of the sludge storage chamber 5.

[0015] When this invention is in operation, the plant-based beverage enters the tank 1 through the inlet 2 and passes through each cylindrical filter 6 from the outside to the inside, thus filtering the beverage sequentially. The purer plant-based beverage enters the innermost filter 6 and is then discharged through the drain pipe 12. During this process, the motor 7 is started, which drives the vertical shaft 8 to rotate. The vertical shaft 8 drives the connecting rod to rotate, which in turn drives the brush 9 and scraper 10 to rotate. The bristles of the brush 9 brush off the plant fibers and other impurities adhering to the filter 6. The impurities fall to the bottom of the filter chamber 4 and are then carried by the scraper 10 into the sludge storage pipe 11. When the impurities accumulated in the sludge storage pipe 11 reach a certain level, the valve is opened, and the impurities fall into the sludge storage chamber 5 for storage. The valve is then closed, allowing the plant fibers and other impurities in the plant-based beverage to be stored in the sludge storage chamber 5 for periodic discharge. In the aforementioned operation, this invention uses a rotating brush 9 to clean the surface of the filter screen 6, preventing clogging of the filter screen 6 and effectively maintaining its filtration efficiency over long-term use. Secondly, the multi-layer filter screen 6 structure allows for multiple layers of filtration of the plant-based beverage, ensuring effective filtration. Furthermore, during the filtration process, a scraper 10 removes plant fibers and other impurities from the bottom and pushes them into the storage pipe 11 for temporary storage. The valve is periodically opened based on the amount of impurities stored in the storage pipe 11 to promptly discharge these impurities, and then the valve is closed again. The impurities then fall into the storage chamber 5 and are periodically discharged. The entire cleaning process of plant fibers and other impurities is automated, eliminating the need to shut down the filtration system. This online cleaning eliminates the need for frequent cleaning of the filter components, allowing the entire system to operate normally for extended periods. This improves the production efficiency of the plant-based beverage, avoids the risk of contamination caused by manual cleaning of the filter components, and reduces the workload and production costs for workers.

[0016] The filter screen 6 has several inwardly recessed annular grooves 13 arranged at intervals from top to bottom. The arrangement of the annular grooves 13 can greatly increase the effective filtration area of ​​the filter screen 6, thereby improving the filtration efficiency of plant beverages.

[0017] A backwash pipe 14 is installed on the drain pipe 12. When the system has completed the filtration of the plant beverage and is in a stopped state, clean water can be introduced into the backwash pipe 14. The clean water first enters the innermost filter screen 6 and, in the process of flowing outward, realizes the backwashing of each layer of filter screen 6. During the backwashing process, the valve on the sludge storage pipe 11 can be opened, and the sewage first flows into the sludge storage chamber 5 through the sludge storage pipe 11 to continue cleaning the sludge storage chamber 5, and finally discharges.

[0018] To improve the filtration efficiency of plant-based beverages, the mesh diameter of multiple filter screens 6 gradually decreases from the outside to the inside. This structure filters the plant-based beverages step by step, first filtering out larger impurities and then filtering out smaller impurities step by step, which can effectively improve the filtration efficiency of plant-based beverages.

[0019] A return pipe 15 is installed at the upper part of the sludge storage chamber 5, and the end of the return pipe 15 is connected to the filter chamber 4. A return pump is installed on the return pipe 15. During the operation of this utility model, impurities such as plant fibers in the plant beverage will be deposited in the sludge storage chamber 5. After a period of time, the upper layer of the sludge storage chamber 5 is pure plant beverage. In order to avoid waste, the return pump can be started to pump this part of the plant beverage back into the filter chamber 4 for continued use, thereby reducing the loss and waste of the plant beverage.

[0020] Each scraper 10 has a cone 16 installed in the annular space above it. The cone 16 has a structure with a larger upper end and a smaller lower end. The upper end of the cone 16 is fixedly connected to the corresponding filter screen 6. The upper end of the outermost cone 16 is fixedly connected to the tank 1, and the lower end of the cone 16 is suspended, with a gap between the lower end of the cone 16 and the corresponding filter screen 6. When this invention is in operation, the brush 9 brushes off impurities such as plant fibers adhering to the filter screen 6. These impurities fall to the bottom of the filtration chamber 4. When the scraper 10 cleans these impurities, they inevitably cause them to fly around and may even mix back into the plant beverage, increasing the filtration difficulty. To avoid this, the cone 16 is provided. The gap between the lower end of the cone 16 and the filter screen 6 allows impurities such as plant fibers to fall off. At the same time, the cone 16 effectively limits the area and range of impurity flying around, ensuring the filtration efficiency of the filter screen 6.

[0021] When this utility model is in operation, impurities such as plant fibers will be deposited in the sludge storage chamber 5, and then it will be cleaned regularly. In order to facilitate the cleaning work and achieve automatic cleaning, a screw conveyor can be installed at the bottom of the sludge storage chamber 5. The screw blades of the screw conveyor will push the impurities out of the sludge storage chamber 5, eliminating the need for manual labor and improving the cleaning efficiency of impurities.
