Description

Technical Field

[0001] This utility model relates to the technical field of plant blight processing devices, specifically an extraction and filtration device for processing a composition for preventing and controlling asparagus stem blight. Background Technology

[0002] Asparagus, a nutritious and economically valuable vegetable crop, is widely cultivated globally. However, asparagus stem blight remains one of the major diseases hindering the healthy development of the asparagus industry. This disease, caused by a fungus, is highly susceptible to outbreaks during asparagus growth, especially in hot and humid environments. It can lead to wilting and breakage of asparagus stems, severely impacting yield and quality, and causing significant economic losses to growers. Compositions for controlling asparagus stem blight typically consist of various natural or synthetic substances with antibacterial and bacteriostatic activities. These substances work synergistically to effectively inhibit the growth and reproduction of pathogens, thereby achieving disease control. To ensure the quality and effectiveness of the composition, the extraction and filtration processes during processing are crucial.

[0003] In the processing of compositions for controlling asparagus stem blight, many traditional extraction devices employ simple heating methods, such as directly heating the extraction container externally, resulting in uneven temperature distribution within the extraction cylinder. Excessively high temperatures near the heat source may cause decomposition or destruction of the active ingredients in the raw material; conversely, excessively low temperatures further away from the heat source lead to incomplete extraction of the active ingredients, reducing extraction efficiency and the quality of the extract. During the transfer of the extract from the extraction container to the filtration device, the lack of effective sealing and protection measures makes the extract susceptible to contamination by external microorganisms, dust, and other pollutants, thus affecting the purity and stability of the composition.

[0004] Most existing filtration devices employ a single filtration method, resulting in limited filtration precision and difficulty in effectively removing minute impurities and suspended particles from the extract. These impurities not only affect the appearance and quality of the composition but may also clog nozzles and other equipment during subsequent use, reducing the control effect. During filtration, impurities easily accumulate on the surface of the filter components, leading to increased filtration resistance and slower filtration speed. After prolonged use, the filter components become severely clogged, requiring frequent replacement or cleaning, increasing production costs and labor intensity. Furthermore, after the extraction and filtration operation, a large amount of raw material residue, extract, and impurities remain inside the device. Existing cleaning methods mostly rely on manual rinsing, which is not only inefficient but also yields unsatisfactory cleaning results. Manual rinsing makes it difficult to ensure uniform coverage of all parts of the device with cleaning water. Therefore, there is a need to design an extraction and filtration device for processing compositions used to control asparagus stem blight. Utility Model Content

[0005] The purpose of this invention is to provide an extraction and filtration device for processing a composition for preventing and controlling asparagus stem blight. This device solves the technical problems that traditional filtration methods may not be able to effectively remove tiny impurities when the extract contains a large number of impurities, resulting in insufficient purity of the filtered extract and affecting the quality of the composition. It also addresses the issues that the filter components are easily clogged by impurities after long-term use, reducing filtration efficiency and making cleaning difficult. This invention achieves the goal of optimizing the filtration effect and reducing impurity residue.

Example

[0023] Given that current extracts often contain numerous impurities, traditional filtration methods may not effectively remove minute impurities, resulting in insufficient purity of the filtered extract and affecting the quality of the composition. Furthermore, filter components are prone to clogging after prolonged use, reducing filtration efficiency and making cleaning difficult. The preferred embodiment of the extraction and filtration device for processing a composition for controlling asparagus stem blight provided by this invention is as follows: Figure 1-4 The image shows an extraction and filtration device for processing a composition for preventing asparagus stem blight. It includes a fixed support frame 1, a water tank support plate 11 fixedly installed on the outer wall of the fixed support frame 1, a filter cylinder 2 fixedly installed on the inner wall of the fixed support frame 1, a top cover 3 fixedly installed on the top of the filter cylinder 2 via a fixing bolt, a discharge pipe 4 connected to the bottom of the filter cylinder 2, an extraction cylinder 5 on one side of the fixed support frame 1, an observation window 51 fixedly installed on the outer wall of the extraction cylinder 5, a sealing flip cover 6 hinged to the top of the extraction cylinder 5, and a control display box 7 on the other side of the fixed support frame 1. The device also includes an extraction and filtration cleaning assembly 8, located inside and outside the filter cylinder 2 and inside the extraction cylinder 5. The extraction and filtration cleaning assembly 8 includes: an extraction and filtration section 81 located inside the filter cylinder 2 and inside the extraction cylinder 5; and a cleaning section 82 located inside and outside the filter cylinder 2, and outside and inside the extraction and filtration section 81.

[0024] The extraction and filtration section 81 includes: a heating plate 811, which is fixedly installed on the inner wall of the extraction cylinder 5; a motor 817, the output end of which is provided with a rotating rod 818 via a coupling, and the rotating rod 818 extends into the interior of the filter cylinder 2; a heating resistance wire 812 is wound inside the heating plate 811, and a raw material container 813 is provided inside the heating plate 811, which is fixedly installed on the inner wall of the extraction cylinder 5 by a fixing bolt, and extraction leakage holes 814 are evenly spaced at the bottom of the inner wall of the raw material container 813.

[0025] The raw material barrel 813 is placed below the extraction chamber, and the extraction chamber is equipped with a conveying pump 815. The connection port of the conveying pump 815 is connected to a conveying pipe 816, which moves through the top of the raw material barrel 813 and the extraction cylinder 5 in sequence, and extends into the interior of the filter cylinder 2. The outer wall of the rotating rod 818 is fitted with a filter support plate 819, and the filter support plate 819 is fixedly installed on the inner wall of the filter cylinder 2. There are two sets of the filter support plate 819.

[0026] A filter impurity adsorption core mesh 8110 is fixedly installed on the top of the filter support plate 819, and a filter adsorption core is provided inside the filter impurity adsorption core mesh. An outlet bucket 8111 is fixedly installed on the bottom of the filter support plate 819, and the outlet bucket 8111 is sleeved on the outer wall of the rotating rod 818 through a bearing. The bottom of the outlet bucket 8111 is connected to the discharge pipe 4.

[0027] Furthermore, in this embodiment, a heating plate 811 with a heating resistance wire 812 inside provides a stable heat source for the extraction cylinder 5, accelerating the dissolution of the effective components of the raw material and improving the extraction efficiency. Combined with the extraction leakage hole 814 at the bottom of the raw material container 813, the extract can smoothly enter the extraction chamber, ensuring a smooth extraction process. Simultaneously, the delivery pump 815 and delivery pipe 816 within the extraction chamber can accurately deliver the extract to the filter cylinder 2, reducing loss and contamination risks during delivery. Next, two sets of filter support plates 819 provide stable support for the filter impurity adsorption core 8110, whose internal adsorption core can effectively adsorb impurities. Combined with the discharge bucket 8111, the filtered solution is guided to the discharge pipe 4, achieving effective discharge of the filtrate. Example

[0028] Please see Figures 1-4 Furthermore, based on Embodiment 1, the cleaning part 82 includes: a connecting long frame 821, which is fixedly installed on the outer wall of the filter cylinder 2, and the inner side wall of the connecting long frame 821 has an installation groove that extends into the interior of the filter cylinder 2; a water tank 8210, which is fixedly installed on the top of the water tank support plate 11; a fixed long water box 822 is fixedly installed on the inner wall of the connecting long frame 821, and cleaning nozzles 823 are uniformly and evenly connected to the inner side wall of the fixed long water box 822, and a connecting hose 824 is connected to the inner side wall of the fixed long water box 822.

[0029] The other end of the connecting hose 824 is connected to a sleeve water box 825, and the sleeve water box 825 is fixedly installed on the outer wall of the rotating rod 818. Spray holes 826 are equidistantly opened on the outer circumference of the sleeve water box 825. An installation ring 827 is provided at the bottom of the sleeve water box 825, and the installation ring 827 is sleeved on the outer wall of the rotating rod 818. There are two sets of installation rings, located above and below the sleeve water box 825 respectively. An L-shaped rod is fixedly installed on the outer wall of the installation ring 827, and an inner ring vertical scraper 828 is fixedly installed on the outer wall of the L-shaped rod.

[0030] The outer wall of the mounting ring 827 is connected by a long L-shaped connecting rod, and an L-shaped outer ring scraper 829 is fixedly installed on the outer wall of the long L-shaped connecting rod. This scrapes the outer wall and top of the filter impurity adsorption core mesh 8110. The interior of the mounting water tank 8210 is equipped with a water pump 8211. The connection port of the water pump 8211 is connected to a water pipe 8212, which movably passes through the top of the mounting water tank 8210 and extends into the interior of the fixed long water box 822.

[0031] Furthermore, in this embodiment, a water tank 8210 is installed, and water is supplied to a fixed long water box 822 via a water pump 8211 and a water pipe 8212. The cleaning nozzle 823 on the tank can perform preliminary rinsing of the inner wall of the filter cylinder 2. The sleeve water box 825 receives the cleaning water through a connecting hose 824. When rotating, the spray hole 826 achieves rotational spraying, expanding the cleaning range and ensuring that all parts are effectively rinsed. Then, the two sets of mounting rings 827 rotate with the rotating rod 818, driving the inner ring vertical scraper 828 to scrape off residual impurities on the inner wall of the filter cylinder 2, and the L-shaped outer ring scraper 829 to scrape off filter impurities and adsorb impurities on the outer wall and top of the core mesh 8110, effectively cleaning the filter components and preventing impurities from accumulating and affecting the subsequent filtration effect.

[0032] In operation, the operator first opens the hinged sealing flap 6 at the top of the extraction cylinder 5 and places the raw material for the asparagus stem blight control composition to be extracted into the raw material container 813 inside the extraction cylinder 5. Then, the sealing flap 6 is closed. Next, the heating plate 811 is activated, and the heating resistance wire 812 wound inside the heating plate 811 begins to work, generating heat to heat the internal environment of the extraction cylinder 5, causing the effective components of the raw material in the raw material container 813 to dissolve in the extraction solvent. During the heating process, the effective components in the raw material enter the extraction chamber through the extraction leakage holes 814 evenly spaced at the bottom of the inner wall of the raw material container 813. Furthermore, a delivery pump 815 is installed inside the extraction chamber. After a certain extraction time, the delivery pump 815 is activated, and the extract in the extraction chamber enters the connected delivery pipe 816 through the connection port of the delivery pump 815. The delivery pipe 816 sequentially moves through the raw material container 813 and the top of the extraction cylinder 5, ultimately delivering the extract to the interior of the filter cylinder 2.

[0033] Furthermore, after the extract enters the filter cylinder 2, it falls onto the filter support plate 819. There are two sets of filter support plates 819, which are fixedly installed on the inner wall of the filter cylinder 2 to provide support. At the same time, the filter impurity adsorption core mesh 8110 fixedly installed on the top of the filter support plate 819 plays a role. The filter adsorption core inside can effectively adsorb impurities in the extract, realizing the preliminary filtration of the extract. After the preliminary filtration, the extract passes through the filter support plate 819 and enters the outlet hopper 8111 fixedly installed at its bottom. The outlet hopper 8111 is sleeved on the outer wall of the rotating rod 818 through a bearing. The bottom of the outlet hopper 8111 is connected to the discharge pipe 4. The filtered extract is finally discharged from the device through the discharge pipe 4, completing the entire filtration process.

[0034] Furthermore, after the filtration operation is completed, the inside of the device needs to be cleaned. First, the water pump 8211 installed inside the installation water tank 8210 is started. The water pump 8211, through the water pipe 8212 connected to its connection port, delivers the cleaning water in the installation water tank 8210 to the inside of the fixed long water box 822. The fixed long water box 822 is fixedly installed on the inner wall of the long frame 821 connected to the outer wall of the filter cylinder 2. The cleaning nozzles 823, which are evenly connected to the inner wall of the filter cylinder 2, start working and spray cleaning water into the inside of the filter cylinder 2 to perform a preliminary rinse.

[0035] A connecting hose 824, installed on the inner wall of the fixed long water box 822, delivers cleaning water to the sleeve water box 825. The sleeve water box 825 is fixedly installed on the outer wall of the rotating rod 818, which is driven by a motor 817. The output end of the motor 817 drives the rotating rod 818 to rotate via a coupling, thereby causing the sleeve water box 825 to rotate accordingly. Spray holes 826, evenly spaced around the outer wall of the sleeve water box 825, evenly spray the cleaning water into all corners of the filter cartridge 2, enhancing the cleaning effect.

[0036] Furthermore, as the sleeve water box 825 rotates, the mounting ring 827 at its bottom also rotates. There are two sets of mounting rings 827, respectively fitted onto the outer wall of the rotating rod 818, located above and below the sleeve water box 825. The upper mounting ring 827 has an L-shaped outer scraper 829 fixedly mounted on its outer wall via a long L-shaped connecting rod. As the rotating rod 818 rotates, the L-shaped outer scraper 829 scrapes the outer wall and top of the filter impurity adsorption core 8110, removing impurities adsorbed on it. The lower mounting ring 827 has an L-shaped rod fixedly mounted on its outer wall, and an inner vertical scraper 828 is fixedly mounted on the outer wall of the L-shaped rod. During rotation, the inner vertical scraper 828 scrapes the inner wall of the filter cylinder 2, further cleaning residual impurities and keeping the device clean for future use.

[0037] Throughout the operation, the control display box 7 is used to control the start-up, stop, and adjustment of operating parameters of each component. The operator can observe the extraction of raw materials in the extraction cylinder 5 through the observation window 51. Through the coordinated operation of the above extraction, filtration, and cleaning processes, the device can stably complete the extraction and filtration of the asparagus stem blight control composition and ensure the cleanliness and hygiene of the device's interior.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
