Description

Technical Field

[0001] The invention relates to the technical field of tea saponin, in particular to an impurity removal device for tea saponin concentrate for clearing ponds, belonging to the technical field of impurity removal devices. Background Art

[0002] Before releasing fish fry, it is necessary to carry out a comprehensive and thorough disinfection of the fish pond, clean up the weeds, miscellaneous fish and various pathogens and other harmful organisms in the fish pond, create a high-quality growth environment for the fish, ensure normal growth, and avoid unnecessary losses. Tea saponin plays a vital role in pond cleaning. As a natural active substance, tea saponin can effectively remove wild fish in shrimp and crab ponds. These wild fish will compete with shrimp and crabs for feed and affect their growth. Tea saponin is safe for shrimp and crabs, and can be used as a pond cleaner to kill wild fish in shrimp and crab breeding ponds, replacing sodium pentachlorophenol, which is highly toxic and seriously pollutes the environment. Tea saponin has a fish poisoning effect, can quickly remove wild fish, and has a short action time, which is The impact on shrimps and crabs is small. At a certain concentration, shrimps and crabs can survive normally. Tea saponin can promote the growth of shrimps, mainly by promoting their molting process. Tea saponin has an inhibitory effect on Candida albicans, Escherichia coli, etc., has a therapeutic effect on shallow fungal infections, and is helpful for the sanitation management of shrimp and crab breeding environments. Tea saponin, also known as tea saponin, is a type of glycoside compound extracted from tea tree seeds. It is a natural surfactant with good performance. As a natural plant pond cleaning agent, the pond cleaning effect of tea dregs is effective with its active ingredient tea saponin. Tea saponin original medicine has strong toxicity to wild fish commonly found in crustacean aquaculture ponds, and can kill wild fish, frog eggs, tadpoles, snails, leeches and pathogenic parasites, but it is not toxic to shrimps and crabs. In the natural environment, tea saponin can be degraded by microorganisms, and its activity disappears completely after 3 to 5 days. It is expected to be developed into an efficient, low-residue, low-toxic, and environmentally friendly aquaculture pond cleaning agent.

[0003] Tea saponin is a pentacyclic triterpenoid saponin compound extracted from tea dregs. It is a natural non-ionic surfactant with certain biological activities such as fish poisoning, antibacterial, antiviral, insecticidal, anti-inflammatory, hypolipidemic and anti-fertility. It is widely used in chemical, pharmaceutical, pesticide, aquatic and food industries. The safe intake of tea saponin for warm-blooded animals is 50-150 mg / kg body weight per day. It is non-toxic when taken orally by humans and animals.

[0004] During the concentration process of tea saponin, the residue of biopolysaccharides often leads to a decrease in the effective content of pentacyclic triterpenoid saponins, which results in the use of tea saponin in shrimp and crab farming. Due to insufficient hemolysis, the use of concentrated tea saponin may not be able to completely remove wild fish from shrimp and crab ponds, which may make shrimp and crab fry easy prey for these fish. This situation may lead to a significant decrease in the yield of shrimp and crab. In extreme cases, farmers may face the dilemma of having no harvest at all. In order to improve the purity of tea saponin, multiple concentration steps are required in the production process to remove biopolysaccharides. This process not only increases the complexity of production and reduces production efficiency, but may also lead to a large waste of manpower, material and financial resources.

[0005] Therefore, a device for removing impurities from tea saponin concentrate in Qingtang is proposed. Summary of the invention

[0006] In view of this, the present invention provides a device for removing impurities from tea saponin concentrate to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0007] The technical solution of the present invention is a device for removing impurities from tea saponin concentrate, comprising: a device support and a device housing fixedly mounted on the top of the device support, a liquid inlet column arranged inside the device housing, and a liquid inlet port arranged at the upper end of the liquid inlet column;

[0008] A liquid storage box is fixedly installed on the inner side of the device support, a filtrate device is fixedly installed at the top center of the liquid storage box, the bottom of the liquid inlet column is located at the center of the filtrate device, a filter mesh plate is arranged inside the filtrate device, a transverse liquid distribution pipe and a longitudinal liquid distribution pipe are arranged on the top of the filter mesh plate, a liquid inlet pipe interface is arranged at the intersection of the transverse liquid distribution pipe and the longitudinal liquid distribution pipe, a filter agent embedding groove is arranged on the inner side of the filtrate device, and a filtrate outlet is arranged at the bottom of the filtrate device.

[0009] Further preferably, the liquid enters the liquid inlet column from the liquid inlet and enters the filtrate device through the liquid inlet pipe interface in the center of the filter screen.

[0010] Further preferably, the liquid inlet column and the device housing are communicated with the press body through a press connecting pipe.

[0011] Further preferably, the device shell is directly welded to the device support, and one side of the liquid inlet column is connected to the press body through a press connecting pipe.

[0012] Further preferably, the liquid inlet column extends to the interior of the filtrate device and is communicated with the top of the liquid inlet pipe interface.

[0013] Further preferably, the filter screen is provided with a mesh groove structure corresponding to the filter medium embedding groove, and the filter medium embedding groove is limitedly installed on the filter screen, which is suitable for paste-shaped or solid filter media;

[0014] After searching in the relevant technologies, in order to solve the comprehensive utilization technology of tea dregs waste, especially to utilize tea dregs waste to produce tea saponin pond cleaning agent with high efficiency, low residue, low toxicity to humans and animals, and environmentally friendly, which is conducive to promoting the sustainable and healthy development of my country's camellia industry and can produce greater economic and social benefits, the publication number is CN1977618A, which discloses a method for preparing tea saponin pond cleaning agent using tea dregs as raw materials. The method for preparing tea saponin pond cleaning agent using tea dregs as raw materials is to vacuum concentrate into a concentrated liquid, add 3 to 10% soluble starch, 0.9 to 1.6% salt and 0.6 to 1.2% calcium hydroxide to the weight of the concentrated liquid, so that the liquid concentration reaches 10 to 15 degrees Baume (60°C), and spray dry into tea saponin pond cleaning agent. The present invention is novel in concept, simple in process, high in extraction efficiency, and low in production cost. The prepared tea saponin pond cleaning agent has the advantages of high efficiency, low residue, low toxicity to humans, animals and aquatic products, and environmental friendliness, and has great promotion significance.

[0015] Further preferably, a drain valve and a drain pipe are installed at the bottom end of the liquid storage box, and the liquid collected in the liquid storage box is discharged through the drain pipe after the drain valve is opened.

[0016] The transverse liquid dispensing tube and the longitudinal liquid dispensing tube are provided with capillary holes, and the filtrate outlet is located at the inner side of the top of the liquid storage box.

[0017] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0018] 1. The present invention securely fixes the device housing on the ground through the synergistic effect of the designed liquid inlet column, filtrate device, filter mesh disk and filter agent embedded groove, uses the device pillar to ensure its stability and durability, opens the press of the press connecting pipe connected to the top of the liquid inlet column, and the press will be used to control the pressure of the liquid flow. The liquid is guided to the filter mesh disk in the filtrate device in the liquid inlet column. In the center of the filter mesh disk, there is a liquid inlet pipe interface, which evenly distributes the liquid to various parts of the filter mesh disk. The liquid is further diverted by the horizontal liquid distribution pipe and the longitudinal liquid distribution pipe on the filter mesh disk. Under the action of gravity, the filtered liquid begins to drip and enters the bottom of the filtrate device. The filtered liquid is discharged through the filtrate outlet and flows into the liquid storage tank. The discharge of the liquid is controlled by the drain valve. In this process, the biopolysaccharide is effectively adsorbed and filtered by the composite filter agent, thereby significantly increasing the proportion of pentacyclic triterpenoid saponins in the concentrate. The desugared concentrate is lighter in color, which shows higher efficiency in removing wild fish in shrimp and crab farming.

[0019] 2. The filtrate device in the present invention comprises a filter mesh disk, the upper end of which is equipped with a transverse liquid separation tube and a longitudinal liquid separation tube. These liquid separation tubes are covered with capillary holes. Through the squeezing action of the liquid inlet column, the concentrated saponin liquid slowly seeps out through the capillary holes, ensuring the thoroughness of the composite filter in the filter agent embedding groove when adsorbing biopolysaccharides. In addition, this design also helps to dilute the color of the concentrated saponin liquid and enhance its application potential in the cosmetics and bathing industries. The rigid structure of the transverse liquid separation tube and the longitudinal liquid separation tube enhances the stability of the filter mesh disk, and can maintain its shape unchanged even when the pressure fluctuates.

[0020] 3. The present invention adopts a pressurized osmotic filtration method, which has significant advantages over traditional single auxiliary filtration methods (such as filter cloth, filter paper). Since the filter agent groove is completely filled with the composite filter agent, the concentrated liquid passes through the filter agent by osmosis rather than direct filtration, effectively adsorbing biopolysaccharides. This method avoids the need for multiple filtrations, shortens the production process, improves production efficiency, reduces the input of labor, solvents and energy consumption, and makes the production process more convenient and efficient.

[0021] Fourth, water is introduced to clean the device through the same press and liquid inlet. The water is diverted on the filter mesh plate, penetrates the filter agent groove, and drips under the action of gravity to complete the cleaning process. The cleaning water is discharged through the filtrate outlet and enters the liquid storage tank. The water collected in the liquid storage tank can be discharged through the drain pipe by opening the drain valve on the drain pipe, ensuring the cleanliness of the inside of the device and preparing for the next use. The process of the present invention is carried out at room temperature. Compared with the high-temperature production environment, it effectively reduces energy consumption. Room temperature filtration reduces solvent loss, improves solvent recovery rate, reduces the diffusion of solvent in the air, reduces the impact on human health, and avoids solvent waste. This not only ensures the safety of production personnel, but also reduces production costs.

[0022] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.

DETAILED DESCRIPTION

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides an impurity removal device for tea saponin concentrate in Qingtang, comprising: a device support 5 and a device shell 3 fixedly installed on the top of the device support 5, a liquid inlet column 2 arranged inside the device shell 3, a liquid inlet port 1 being arranged at the upper end of the liquid inlet column 2, a liquid storage box 8 being fixedly installed on the inner side of the device support 5, a filtrate device 9 being fixedly installed at the top center of the liquid storage box 8, the bottom of the liquid inlet column 2 being located at the center of the filtrate device 9, a filter mesh plate 12 being arranged inside the filtrate device 9, a transverse liquid distribution pipe 13 and a longitudinal liquid distribution pipe 14 being arranged on the top of the filter mesh plate 12, a liquid inlet pipe interface 15 being arranged at the intersection of the transverse liquid distribution pipe 13 and the longitudinal liquid distribution pipe 14, a filter agent embedding groove 16 being arranged on the inner side of the filtrate device 9, a filtrate outlet 4 being arranged at the bottom of the filtrate device 9, liquid enters the liquid inlet column 2 from the liquid inlet port 1, and enters the filtrate device 9 through the liquid inlet pipe interface 15 in the center of the filter mesh plate 12.

[0030] By firmly fixing the device housing 3 on the ground and using the device pillars 5 to ensure its stability and durability, this step is crucial because it provides a solid foundation for the entire filtration system. Open the press of the press connecting pipe 10 connected to the top of the liquid inlet column 2. This press will be used to control the pressure of the liquid flow to ensure that the liquid can pass through the filtration system smoothly. The liquid enters the liquid inlet column 2 through the designed liquid inlet 1. The design of this liquid inlet 1 is to reduce the resistance to liquid flow and prevent impurities from entering. The liquid is guided to the filter screen 12 in the filtrate device 9 in the liquid inlet column 2. In the center of the filter screen 12, there is an inlet pipe interface 15, which evenly distributes the liquid to various parts of the filter screen 12. The liquid is further diverted on the filter screen 12 by the horizontal liquid distributor 13 and the longitudinal liquid distributor 14, thereby achieving uniform penetration of the tea saponin concentrate in the filter agent. In this process, the biopolysaccharide is effectively adsorbed and filtered by the composite filter agent, thereby significantly increasing the proportion of pentacyclic triterpenoid saponins in the concentrate. The concentrate after desugaring is lighter in color, which shows higher efficiency in removing wild trash fish in shrimp and crab farming.

[0031] Reference Figure 2 The liquid inlet column 2 and the device shell 3 are connected to the press body 11 through a press connecting pipe 10. The device shell 3 is directly welded to the device support 5, and one side of the liquid inlet column 2 is connected to the press body 11 through a press connecting pipe 10.

[0032] The liquid is guided in the liquid inlet column 2 to the filter screen 12 in the filtrate device 9. In the center of the filter screen 12, there is a liquid inlet pipe interface 15, which evenly distributes the liquid to various parts of the filter screen 12. The liquid is further diverted by the horizontal liquid distribution pipe 13 and the longitudinal liquid distribution pipe 14 on the filter screen 12. The design of these liquid distribution pipes helps to improve the filtration efficiency. The liquid then penetrates into the filter agent embedded groove 16 of the mesh groove.

[0033] Reference Figure 2 The liquid inlet column 2 extends to the interior of the filtrate device 9 and is connected to the top of the liquid inlet pipe interface 15. A mesh structure corresponding to the filter agent embedding groove 16 is provided on the filter mesh plate 12. The filter agent embedding groove 16 is limitedly installed on the filter mesh plate 12 and is suitable for paste or solid filter agents.

[0034] The filtrate device 9 includes a filter mesh plate 12, and a transverse liquid separation tube 13 and a longitudinal liquid separation tube 14 are provided at the upper end thereof. These liquid separation tubes are covered with capillary holes. Through the squeezing action of the liquid inlet column 2, the concentrated saponin liquid slowly seeps out through the capillary holes, thereby ensuring the thoroughness of the composite filter in the filter agent groove 16 in adsorbing biopolysaccharides. In addition, this design also helps to dilute the color of the concentrated saponin liquid. The filtered liquid begins to drip and enters the bottom of the filtrate device 9. This process ensures that the liquid and the filter have sufficient contact time to achieve the best filtering effect. The filtered liquid is discharged through the filtrate outlet 4 and flows into the liquid storage box 8. The design of the liquid storage box 8 takes into account the collection and storage of the liquid, thereby ensuring that the filtered liquid can be safely stored.

[0035] Reference Figure 2 The bottom of the liquid storage box 8 is provided with a drain valve 6 and a drain pipe 7. The liquid collected in the liquid storage box 8 is discharged through the drain pipe 7 after the drain valve 6 is opened. Capillary holes are provided on the transverse liquid separation pipe 13 and the longitudinal liquid separation pipe 14. The filtrate outlet 4 is located on the inner side of the top of the liquid storage box 8.

[0036] Through the same press and liquid inlet 1, water is introduced to clean the device. The water is diverted on the filter mesh plate 12, permeates the filter agent embedded groove 16, and drips under the action of gravity. The cleaning process is completed. The cleaning water is discharged through the filtrate outlet 4 and enters the liquid storage box 8. The water collected in the liquid storage box 8 can be discharged through the drain pipe 7 by opening the drain valve 6 on the drain pipe 7, thereby ensuring that the inside of the device is clean and ready for the next use.

[0037] When the present invention is working: the device shell 3 is firmly fixed on the ground, and the device pillar 5 is used to ensure its stability and durability. This step is crucial because it provides a solid foundation for the entire filtration system. The press of the press connecting pipe 10 connected to the top of the liquid inlet column 2 is opened. This press will be used to control the pressure of the liquid flow to ensure that the liquid can pass through the filtration system smoothly. The liquid enters the liquid inlet column 2 through the designed liquid inlet 1. The design of this liquid inlet 1 is to reduce the resistance to liquid flow and prevent impurities from entering. The liquid is guided to the filter screen 12 in the filtrate device 9 in the liquid inlet column 2. In the center of the filter screen 12, there is a liquid inlet pipe interface 15, which evenly distributes the liquid to various parts of the filter screen 12. The liquid is distributed on the filter screen 12 by a horizontal distribution pipe 13 and the longitudinal liquid distributor 14 are further divided. The design of these liquid distributors helps to improve the filtration efficiency. The liquid then penetrates into the filter medium embedded groove 16 of the mesh groove. The filter medium here is specially used to capture and remove impurities in the liquid. Under the action of gravity, the filtered liquid begins to drip and enters the bottom of the filtrate device 9. This process ensures that the liquid and the filter medium have sufficient contact time to achieve the best filtration effect. The filtered liquid is discharged through the filtrate outlet 4 and flows into the liquid storage box 8. The design of the liquid storage box 8 takes into account the collection and storage of the liquid, ensuring that the filtered liquid can be safely stored. A drain pipe 7 is connected to the bottom of the liquid storage box 8, and the discharge of the liquid is controlled by the drain valve 6. This system allows the user to collect or discharge the filtered liquid as needed, providing operational flexibility.

[0038] After use, water is introduced through the same press and liquid inlet 1 to clean the device. The water is diverted on the filter mesh plate 12, permeates the filter agent embedded groove 16, and drips under the action of gravity to complete the cleaning process. The cleaning water is discharged through the filtrate outlet 4 and enters the liquid storage box 8. The water collected in the liquid storage box 8 can be discharged through the drain pipe 7 by opening the drain valve 6 on the drain pipe 7, thereby ensuring that the inside of the device is clean and ready for the next use.

[0039] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
