Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation broth filtration technology, specifically a continuous filtration system for plant fermentation broth. Background Technology
[0002] Plant fermentation broth is widely used in agriculture, food, medicine, and cosmetics. Through fermentation, the active ingredients in plants can be extracted, enhancing nutritional value and improving product functionality. Fermentation broth contains abundant active ingredients such as amino acids, phenolic compounds, and microbial metabolites, which have important applications in multiple fields. However, when processing large volumes of liquid, the processing speed of traditional filtration technologies often cannot meet industrial demands. Because plant fermentation broth contains a large amount of suspended solids and fine particles, traditional filtration methods often fail to effectively remove these impurities, leading to reduced product purity.
[0003] However, existing technologies still have significant shortcomings, such as:
[0004] In order to better filter out particles in the fermentation liquid, existing plant fermentation liquid filtration systems often use filters with small pores. However, this makes them very prone to clogging. Once a blockage occurs, the entire device needs to be shut down, and filtration can only continue after the blockage is cleared, which greatly affects production efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a continuous filtration system for plant fermentation liquid to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A continuous filtration system for plant fermentation liquid includes several filter tanks, each with an inlet pipe and an outlet pipe on both sides, the inlet pipe being positioned above the outlet pipe.
[0008] A branch infusion pipe and a main infusion pipe are provided on one side of the infusion pipe. The main infusion pipe and the branch infusion pipe are connected. The infusion pipe is connected to the main infusion pipe through the branch infusion pipe.
[0009] One side of the outlet pipe is provided with a discharge pipe and a collection outlet pipe, and the outlet pipe is connected to the collection outlet pipe through the discharge pipe and the collection outlet pipe.
[0010] Valves are installed at both the inlet and outlet pipes. A lid is installed on top of the filter bucket. A filter assembly for filtering the fermentation broth is installed inside the filter bucket between the inlet and outlet pipes.
[0011] Preferably, the filter assembly includes vertical rods fixedly and symmetrically arranged at the bottom of the bucket lid, the vertical rods having a plurality of bolt through holes, a plurality of filter screens being movably sleeved on the vertical rods, and a limiting block being movably sleeved on the bottom of the filter screens, the limiting block being fixed to the vertical rods by fixing bolts;
[0012] The filter plate and the limiting block are connected by a spring, which is sleeved on the vertical rod.
[0013] Preferably, the number of filter plates is not less than three, the middle part of the filter plate is arc-shaped, and the surface of the filter plate is provided with several annular grooves for storing solid impurities in the fermentation broth.
[0014] Preferably, the diameter of the filter holes on the filter plate decreases sequentially from top to bottom, the filter plate is circular like the filter barrel, and a sealing ring is fixedly provided on the outer periphery of the filter plate.
[0015] Preferably, the bottom of the vertical rod is provided with threads, and the bottom of the vertical rod is provided with an anti-detachment block, and the anti-detachment block is provided with a threaded hole.
[0016] Preferably, the filter holes on each layer of the filter screen are staggered.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. By using multiple filter tanks connected by branch and branch infusion pipes and valves, it is ensured that when a filter in the system malfunctions, only the corresponding valve needs to be closed and the filter tank can be cleaned individually. When blockage occurs, it will not affect the normal operation of the entire system, thus ensuring production efficiency.
[0019] 2. By setting up the filter components, multi-stage filtration of the filtrate is achieved, ensuring more thorough filtration. The setting of limit block springs and annular grooves reduces the possibility of the entire filtration system being blocked. At the same time, the entire filter components are set on the lid, making it easy to remove, replace and clean. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 This utility model provides a technical solution:
[0028] A continuous filtration system for plant fermentation broth includes several filter tanks 1. Each filter tank 1 has an inlet pipe 2 and an outlet pipe 3 on both sides. In this embodiment, three filter tanks 1 are provided. Each filter tank 1 has an inlet pipe 2 and an outlet pipe 3 on both sides. The inlet pipe 2 is positioned above the outlet pipe 3. This arrangement ensures that the filtrate entering through the inlet pipe 2 is filtered not only by the action of the supply pump but also by gravity. A branch inlet pipe 4 and a main inlet pipe 5 are provided on one side of the inlet pipe 2, and the main inlet pipe 5 and the branch inlet pipe 4 are connected. The inlet pipe 2 is connected to the main inlet pipe 5 through the branch inlet pipe 4. An outlet pipe 6 and a converging outlet pipe 7 are provided on one side of the outlet pipe 3, and the outlet pipe 3 is connected to the converging outlet pipe 7 through the outlet pipe 6.
[0029] The inlet pipe 2 of the filter tank 1 is connected to multiple branch inlet pipes 4 and then to the main inlet pipe 5. The main inlet pipe 5 is supplied with liquid by an inlet pump. The outlet pipe 3 is connected to the outlet pipe 6 and the main outlet pipe 7. When a blockage occurs in one of the filter tanks 1, the corresponding valve 8 can be closed, and the blockage can be cleared individually without affecting the normal operation of other filter tanks 1, greatly improving work efficiency. Even if no blockage occurs, the filter tank 1 can be maintained independently. In actual use, flow rate sensors can be installed on each outlet pipe 3 to determine whether the filter tank 1 is blocked. This is a technology and device familiar to those skilled in the art, and will not be described in detail here.
[0030] Valves 8 are installed at both the inlet pipe 2 and the outlet pipe 3. A lid 9 is installed on the top of the filter bucket 1. A filter assembly for filtering the fermentation liquid is installed inside the filter bucket 1 between the inlet pipe 2 and the outlet pipe 3. In this embodiment, the lid 9 is bolted to the top of the filter bucket 1. The filter assembly is located at the bottom of the lid 9. When the lid 9 is placed, the filter assembly can enter the filter bucket 1 to achieve the filtering effect on the fermentation liquid.
[0031] The filter assembly includes vertical rods 10 symmetrically arranged at the bottom of the lid 9. Each vertical rod 10 has several bolt through holes 11. In this embodiment, two vertical rods 10 are symmetrically arranged at the bottom of the lid 9. The vertical rods 10 are made of corrosion-resistant, high-strength metal. Three filter screen plates 12 are fitted onto each vertical rod 10. Multiple filter screen plates 12 are movably fitted onto the vertical rod 10. A limiting block 13 is movably fitted onto the bottom of each filter screen plate 12 and is fixed to the vertical rod 10 by fixing bolts 14. The filter screen plates 12 and the limiting blocks 13... The two filter plates 12 are connected by a spring 15, which is sleeved on the vertical rod 10. During use, the position of the limiting block 13 is first adjusted and fixed. Adjusting the position of the limiting block 13 is equivalent to adjusting the position of the filter plate 12, which can adjust the size of the space between the two filter plates 12 to ensure the filtration effect. In actual use, the space between the two filter plates 12 increases from top to bottom. Because the filter holes of the uppermost filter plate 12 are the largest, fermentation liquid is unlikely to accumulate on the upper side, so the required space is smaller.
[0032] The number of filter plates 12 is not less than three. The middle part of the filter plate 12 is arc-shaped. The surface of the filter plate 12 is provided with several annular grooves 16 for storing solid impurities in the fermentation liquid. The arc shape of the filter plate 12, coupled with the fact that the flow rate of the fermentation liquid entering the filter tank 1 cannot always remain constant, causes the filter plate 12 to vibrate under the action of the spring. When vibrating, the impurities can move to both sides of the filter plate 12. The annular grooves 16 ensure that more impurities can be stored on both sides of the filter plate 12, reducing the probability of the filter plate 12 becoming clogged. When the accumulation of impurities affects the normal filtration of the filter plate 12, the corresponding valve 8 can be closed, and then maintenance can be performed.
[0033] The diameter of the filter holes on the filter screen plate 12 decreases from top to bottom. The filter screen plate 12 is circular, consistent with the filter barrel 1. A sealing ring 17 is fixedly installed on the outer periphery of the filter screen plate 12. The filter holes on each layer of the filter screen plate 12 are staggered. The bottom of the vertical rod 10 is provided with a thread 18 and an anti-detachment block 19. The anti-detachment block 19 has a threaded hole 20. In this embodiment, the anti-detachment block 19 is used to limit the bottom. The connection between the thread 18 and the threaded hole 20 ensures that the filter screen plate 12 can be removed for maintenance. At the same time, the filter holes on the filter screen plate 12 decrease from top to bottom, ensuring that the fermentation can also achieve a multi-layer filtration effect. The sealing ring 17 ensures the sealing between the filter screen plate 12 and the inner wall of the filter barrel 1. A sealing ring can also be set at the position where the filter screen plate 12 and the vertical rod 10 are fitted. Here, the sealing ring is set on the filter screen plate 12.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
