Description

Technical Field

[0001] The present application relates to the technical field of solid-liquid extraction, and in particular to a solid-liquid extraction device for organic pretreatment. Background Art

[0002] In the field of modern analytical testing, solid-liquid extraction before machine treatment plays an irreplaceable and important role as a key separation technology for extracting target components from solid samples. It is based on the difference in solubility of solutes in different solvents. By making the solid sample fully contact with the appropriate solvent, the target solute is transferred from the solid phase to the liquid phase solvent. It is widely used in many fields such as environmental monitoring and drug development. For example, in environmental monitoring, organic pollutants in soil samples are analyzed, and in drug development, effective ingredients are extracted from solid raw materials such as botanicals. In the solid-liquid extraction process, the reasonable selection of solvents, means to improve extraction efficiency (such as stirring, oscillation, heating, etc.), and subsequent separation and purification of the extract and solid residue all play a decisive role in accurately determining the content or properties of the target components.

[0003] With technological advancements, a number of solid-liquid extraction devices have emerged. For example, the solid-liquid extraction device for organic pretreatment disclosed in Chinese Patent Publication No. "CN220194043U" effectively enhances the filtration efficiency during solid-solution reactions by providing multiple layers of filter plates with increasing mesh size from top to bottom. Furthermore, the box-shaped filter plates better store the reacted solids, preventing the discharged liquid from containing particulate impurities. Furthermore, the spacing between adjacent filter plates can be controlled by a limiting tube to enhance the extraction effect.

[0004] However, the existing technology still has many problems that need to be solved. In actual use, the top of the filter plate of the device lacks a stirring and scraping structure, which makes the impurities filtered out during application easily adhere to the top of the filter mesh. As the filtration continues, the impurities will gradually clog the filter mesh, seriously affecting the overall filtration efficiency. In addition, when disassembling and assembling the filter mesh, they need to be taken out from the inside of the device one by one. The operation is cumbersome and difficult to achieve quick disassembly, which greatly limits work efficiency and convenience. In summary, the existing solid-liquid extraction device has obvious defects in structural design and functional realization, and urgently needs innovative and improved design to meet the ever-evolving analysis and detection needs.

[0016] In summary, this application has the following beneficial technical effects: The device is provided with an adjustment mechanism, which can effectively improve the convenience and efficiency of maintenance during use. When the device needs maintenance, the second motor is started, and the motor drives the gear connected thereto to rotate. Since the gear is precisely meshed with the rack, the rotation of the gear drives the rack to move, thereby causing the movable frame to slide smoothly in the vertical rail. The upward movement of the movable frame drives the lifting frame and the top plate to move up, and the filter device is slowly pulled out from the tank body. The staff can conduct a comprehensive and detailed maintenance and cleaning of the tank body and the filter device. After the maintenance is completed, the second motor is started to rotate in the opposite direction, and the movable frame moves down, driving the lifting frame to descend, and the filter device is accurately inserted into the tank body. In addition, after the filter device is pulled out, the round frame can be pulled out to slide on the mounting block.

During installation, each support shaft is inserted into the limit arc groove, and the support shaft and the limit arc groove slide and limit each other to ensure that the circular frame is firmly installed inside the tank body. The feeding valve is opened, and the material to be processed is guided by the feeding hopper and smoothly enters the tank body. When the device is in use, the internal filter mesh apertures of multiple equally spaced circular frames are uniquely designed, and the top filter mesh aperture is larger than the bottom. This design allows the material to be filtered layer by layer. The sophisticated layout of multi-layer filtration allows impurities of different sizes to be gradually intercepted, effectively improving the overall filtering effect of the device and providing high-quality filtrate for subsequent processing. During the processing of this equipment, the first motor can be started to drive the connecting shaft to rotate, and then drive the rotating shaft to rotate. The mutual limitation of the support shaft and the limiting arc groove ensures that the circular frame is stable inside the tank body. The rotating sleeve enables the rotating shaft to rotate flexibly on the mounting block inside the circular frame, while the circular frame remains stationary. The rotation of the rotating shaft drives the mounting plate and the mounting frame to rotate. Under the reset action of the telescopic spring, the brush plate on the inside of the mounting frame stably brushes the top of the filter screen. The support rod assists in supporting the telescopic spring to prevent the filter screen from being blocked by impurities, thereby improving the filtration stability. At the same time, the rotating shaft drives the bottom auger to rotate, stirring the solution at the bottom of the tank and making it surge downward. The solution flows back upward through the reflux pipe, and the electric heating coil is started to heat the solution, causing it to roll up and down, realizing continuous circulation filtration, which not only improves the filtration effect, but also makes the temperature evenly distributed inside the tank body, comprehensively improving the solid-liquid extraction effect, and ensuring the efficient and stable operation of the device.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-9 This application is described in further detail.

[0020] The present application discloses a solid-liquid extraction device for organic pretreatment. Figure 1-9 As shown, it includes a base frame 1, a tank body 2 is fixedly installed on the inner side of the base frame 1, an adjusting mechanism 3 is fixedly installed on the middle of the top rear side of the tank body 2, a filtering device 6 is fixedly installed on the top of the adjusting mechanism 3, and the bottom of the filtering device 6 is inserted into the interior of the tank body 2, a drain valve 4 is fixedly installed on the bottom output end of the tank body 2, the input end of the drain valve 4 is connected to the bottom of the tank body 2, and a drain pipe 5 is fixedly installed on the output end of the drain valve 4, and a reflux pipe 7 is fixedly installed at an equal interval on the lower end of the outer surface of the tank body 2, the output end of the reflux pipe 7 is connected to the bottom of the tank body 2, and the output end of the reflux pipe 7 is connected to the top of the tank body 2, and an electric heating coil is fixedly installed on the inner wall of the bottom of the tank body 2; The filtering device 6 includes a top plate 61, which is fixedly mounted on the top of the adjusting mechanism 3. A first motor 62 is fixedly mounted on the top front end of the top plate 61. The output end of the first motor 62 passes through the top plate 61 and is fixedly mounted with a connecting shaft 63. The bottom of the connecting shaft 63 is rotatably connected to a top cover 64. The bottom of the top cover 64 is rotatably connected to a filtering mechanism 66. The filtering mechanism 66 is movably mounted inside the tank body 2. The top of the filtering mechanism 66 is connected to the bottom of the connecting shaft 63. The base frame 1 of the device supports and fixes the tank body 2. When performing solid-liquid extraction operations, the adjusting mechanism 3 can control the lifting and lowering of the filtering device 6. When the filtering device 6 needs to be inserted into the tank body 2 for work, the adjusting mechanism 3 operates, pushing the top plate 61 and the connected filtering device 6 downward, so that the filtering mechanism 66 smoothly enters the tank body 2. At this time, the organic mixed liquid to be treated can enter the tank body 2, and the first motor 62 is started. Its output end drives the connecting shaft 63 to rotate, and the connecting shaft 63 further drives the filtering mechanism 66 to operate. The components in the filtering mechanism 66 work together to filter the mixed liquid. During the filtration process, the electric heating coil at the bottom of the tank body 2 can heat the mixed liquid to assist the solid-liquid extraction process. At the same time, the reflux pipe 7 transports the liquid at the bottom of the tank body 2 to the top, forming a circulation and improving the extraction effect. After the filtration is completed, the drain valve 4 is opened, and the treated liquid is discharged through the drain pipe 5.

[0021] Please refer to Figure 4-Figure 8The mounting assembly 662 includes a mounting groove 6621 and a rotating sleeve 6622. The rotating sleeve 6622 is arranged linearly at equal intervals and is rotatably connected to the outer surface of the rotating shaft 661. The mounting groove 6621 is opened on one side of the circular frame 663. The outer surface of the rotating sleeve 6622 is fixedly connected to a mounting block 6623. The mounting block 6623 is slidably connected to the inner side of the mounting groove 6621. The stirring assembly 665 includes a mounting plate 6651. The mounting plate 6651 is arranged linearly at equal intervals and is fixedly connected to the outer surface of the rotating shaft 661. The mounting plates 6651 are all arranged at the upper end of each circular frame 663. The mounting plates 665 1 is fixedly installed on one side of the mounting frame 6652, and the interior of the mounting frame 6652 is fixedly connected to the telescopic springs 6653 arranged linearly at equal intervals. The bottom of the telescopic spring 6653 is fixedly connected to the slide plate 6654, and the bottom of the slide plate 6654 is fixedly connected to the brush plate 6655. The top ends of the slide plate 6654 are fixedly connected to the support rod 6656. The end of the support rod 6656 passes through the mounting frame 6652. The support rod 6656 and the mounting frame 6652 are slidably connected. The overall cross-sectional shape of the mounting groove 6621 and the cross-sectional shape of the mounting block 6623 are both cross-shaped. The mounting assembly is adopted. The components 662 and the stirring component 665 work together, so that in the installation link, since the rotating sleeves 6622 are arranged linearly at equal intervals and are rotatably connected to the outer surface of the rotating shaft 661, the mounting blocks 6623 fixed on the outer surface can be connected to the mounting grooves 6621 by sliding, so that the round frame 663 can be easily installed on the rotating shaft 661. The mounting grooves 6621 and the mounting blocks 6623 are both cross-shaped in cross section, which ensures the stability of the connection and the accuracy of positioning. When the equipment is running, the rotating shaft 661 rotates, driving the mounting plates 6651 fixed on its outer surface to rotate synchronously. The mounting plates 6651 are located at each At the upper end of the circular frame 663, a telescopic spring 6653 in a mounting frame 6652 on one side thereof will produce telescopic changes due to its own elasticity and mechanical movement when the device is running. The slide plate 6654 connected to the bottom of the spring can move up and down under the action of the spring, driving the bottom brush plate 6655 to brush the filter screen in the circular frame 663. The support rods 6656 at both ends of the top of the slide plate 6654 pass through the mounting frame 6652 and can be slidably connected to it, playing an auxiliary support and guiding role, ensuring the stability of the brush plate 6655 during the up and down movement, thereby effectively preventing the filter screen from being blocked by impurities and maintaining the filtering effect.

[0022] Please refer to Figures 1-4 and Figure 9The cam 331 is fixed to the rear end of the base 1, and the cam 332 is fixed to the rear end of the base 1, and the cam 333 is fixed to the rear end of the base 1, and the cam 333 is fixed to the rear end of the base 1. When the device 6 is lifted and adjusted, the driving component 33 plays a key role, starting the second motor 333, and the motor output end drives the gear 334 to rotate. Since the gear 334 is meshed with the rack 331 fixed to the back side of the vertical rail 32, the rotation of the gear 334 is converted into a linear motion of the rack 331, thereby driving the movable frame 332 to slide smoothly inside the vertical rail 32. The movable frame 332 is connected to the lifting frame 34, and the sliding of the movable frame 332 drives the lifting frame 34 to move synchronously, and the top of the lifting frame 34 is fixedly connected to the top plate 61 of the filter device 6. In this way, the movement of the lifting frame 34 can accurately drive the top plate 61 and its connected filter device 6 to rise or fall, so as to meet the equipment's requirements for the position of the filter device 6 in different working stages. For example, before starting the equipment, the filter device 6 is lowered and inserted into the tank body 2, and the filter device 6 is raised for operation during inspection and maintenance.

[0023] Please refer to Figure 4-Figure 8The filter mechanism 66 includes a rotating shaft 661, which is rotatably connected to the middle of the bottom of the top cover 64. The top of the rotating shaft 661 is connected to the bottom of the connecting shaft 63. The outer surface of the rotating shaft 661 is rotatably connected to the mounting assembly 662 at equal intervals. A round frame 663 is movably installed on the outer side of the mounting assembly 662. A filter screen 664 is fixedly installed at the bottom of the round frame 663. The outer surface of the rotating shaft 661 is located at the top of the mounting assembly 662 and is provided with a stirring assembly 665. The lower end of the outer surface of the rotating shaft 661 is fixedly connected to the filter screen 664. The auger 69 is connected, and the support shaft 666 is fixedly connected to the tank body 2 in an annular arrangement at equal intervals. The outer side of the circular frame 663 is provided with a limited arc groove 667 at equal intervals. The support shaft 666 and the limited arc groove 667 are slidably connected. When the filtering mechanism 66 of the device is working, when the first motor 62 drives the connecting shaft 63 to rotate, the rotating shaft 661 connected to the bottom of the connecting shaft 63 rotates accordingly, and the rotating shaft 661 is rotatably connected to the bottom of the top cover 64 to provide power for the operation of the entire filtering mechanism 66. The outer surface of the rotating shaft 661 is rotatably connected to the top cover 64 at equal intervals. The mounting assembly 662 enables the circular frame 663 to be easily mounted on the rotating shaft 661. The filter screen 664 fixed at the bottom of the circular frame 663 is a key component for filtering and is used to intercept impurities. The stirring assembly 665 located on the top of the mounting assembly 662 on the outer surface of the rotating shaft 661 operates synchronously with the rotation of the rotating shaft 661. The mounting plate 6651 drives the mounting frame 6652 to rotate, and the telescopic spring 6653 in the mounting frame 6652 pushes the slide plate 6654 and the brush plate 6655 to brush the top of the filter screen 664. The auger 69 fixed at the lower end of the outer surface of the rotating shaft 661 stirs the solution at the bottom of the tank body 2 when the rotating shaft 661 rotates, promoting solid-liquid mixing and separation. The support shafts 666 arranged in a ring shape in the tank body 2 are slidably connected with the limiting arc groove 667 on the outer side of the circular frame 663, which ensures that the circular frame 663 is firmly installed inside the tank body 2 without hindering the corresponding movement of the circular frame 663 when the rotating shaft 661 rotates, thereby jointly realizing efficient solid-liquid filtration and extraction functions.

[0024] Please refer to Figures 1-4A feeding valve 65 is fixedly installed on one side of the top of the top cover 64. The output end of the feeding valve 65 passes through the top cover 64 and is connected to the interior of the tank body 2. A feeding pipe 67 is fixedly connected to the top of the feeding valve 65. A feeding hopper 68 is fixedly connected to the top of the feeding pipe 67. During use, the material to be processed is first placed in the feeding hopper 68. The feeding hopper 68, with its large opening area, is convenient for centralized feeding of materials. The material enters the feeding pipe 67 connected to it through the feeding hopper 68. The feeding pipe 67 plays the role of guiding the material transmission. The top of the valve 65 is fixedly connected, and the material can flow smoothly into the feeding valve 65. The output end of the feeding valve 65 passes through the top cover 64 and is connected to the interior of the tank body 2. By controlling the opening and closing of the feeding valve 65, the flow rate and speed of the material entering the tank body 2 can be accurately adjusted. When the feeding valve 65 is opened, the material falls into the interior of the tank body 2 through the output end of the feeding valve 65 under the action of gravity, thereby realizing the efficient and stable transportation of the material to be processed into the tank body 2, providing raw material supply for subsequent related process operations in the tank body 2, such as solid-liquid extraction, mixing reaction, etc.

[0025] The implementation principle of the solid-liquid extraction equipment for organic pretreatment in the embodiment of the present application is as follows: the device significantly improves the convenience and efficiency of the equipment in terms of maintenance and repair through the ingeniously designed adjustment mechanism 3. Specifically, during the use of the device, when maintenance and repair operations are required, the second motor 333 can be started. When the second motor 333 is running, it will drive the gear 334 connected thereto to rotate. Since there is a precise meshing connection relationship between the gear 334 and the rack 331, as the gear 334 rotates, under the action of the meshing transmission, the rack 331 will produce corresponding movement, thereby driving the movable frame 332 to slide smoothly inside the vertical rail 32. When the movable frame 332 is driven to move upward, the lifting frame 34 connected thereto will also move upward synchronously, and the upward movement of the lifting frame 34 will push the top plate 61 to move upward. Through such a linkage mechanism, the upward movement of the top plate 61 can drive the filter device 6 to slowly extend from the inside of the tank body 2. At this time, the staff can conveniently carry out comprehensive and detailed maintenance and cleaning of the inside of the tank body 2 and the filter device 6. , after the inspection and cleaning is completed, it is only necessary to start the second motor 333 for reverse rotation. The reverse rotation of the motor will drive the gear 334 to rotate in the opposite direction, thereby causing the movable frame 332 to slide downward inside the vertical rail 32. During the downward movement of the movable frame 332, the lifting frame 34 will also drop accordingly, thereby accurately inserting the filter device 6 into the interior of the tank body 2 and restoring the normal operation of the device. In addition, when the filter device 6 extends out of the tank body 2 and the round frame 663 needs to be removed, the round frame 663 can be pulled out to slide on the mounting block 6623. By utilizing the sliding cooperation between the mounting block 6623 and the mounting groove 6621, each round frame 663 can be easily removed from the mounting block 6623 on the outer surface of the rotating shaft 661, so that the filter screen 664 can be efficiently replaced and cleaned. This series of designs can effectively improve the convenience of the entire device in the subsequent inspection process, and can quickly and easily pull out the filter device 6 inside the entire tank body 2, providing great convenience for the maintenance of the device and further improving the overall filtration efficiency of the device.

[0026] At the same time, the filtering device 6 provided in the present device plays a key role in the entire processing process and has many significant advantages. Before carrying out the processing operation, each circular frame 663 must first be accurately mounted on the outer surface of the mounting block 6623 through the mounting groove 6621. After the mounting is completed, the adjusting mechanism 3 is started to drive the entire filtering device 6 to move downward so that it can be smoothly inserted into the interior of the tank body 2. During the installation process, each support shaft 666 will be inserted exactly into the interior of the limiting arc groove 667. The mutual sliding limiting effect between the support shaft 666 and the limiting arc groove 667 can ensure that the circular frame 663 is accurately mounted on the outer surface of the mounting block 6623. The installation of frame 663 inside the tank body 2 is firm and reliable. At this time, the feeding valve 65 is opened and the material to be processed is added to the inside of the feeding hopper 68. With the help of the auxiliary guiding function of the feeding hopper 68, the material can smoothly pass through the feeding valve 65 into the inside of the tank body 2. During the use of the device, the internal filter apertures of multiple equally spaced circular frames 663 present a unique design feature, that is, the filter apertures at the top are larger than the filter apertures at the bottom. This design enables the material to be filtered layer by layer when passing through the filtering device 6. The ingenious layout of multi-layer filtration effectively improves the overall filtering effect of the device.

[0027] Moreover, during the processing, the first motor 62 can be started to drive the connecting shaft 63 to rotate, and the rotation of the connecting shaft 63 can drive the rotating shaft 661 to rotate. During the rotation of the rotating shaft 661, due to the mutual limiting effect between the support shaft 666 and the limiting arc groove 667, the circular frame 663 can be stably located in a predetermined position inside the tank body 2. It is worth noting that the rotating sleeve 6622 is rotatably connected to the outer surface of the rotating shaft 661, which enables the rotating shaft 661 to flexibly rotate on the mounting block 6623 inside the circular frame 663, while the circular frame 663 remains relatively stationary. The rotation of the rotating shaft 661 will drive the various mounting plates 6651 on its outer surface to rotate synchronously, and the rotation of the mounting plate 6651 will drive the mounting bracket 6652 to rotate. Turn, at this time, the brush plate 6655 on the inside of the mounting frame 6652 will perform a comprehensive and detailed brushing operation on the top of the filter screen 664. During the brushing process, the telescopic spring 6653 will push the slide plate 6654 downward through its own reset effect, thereby ensuring that the brush plate 6655 can always maintain stable contact with the top of the filter screen 664 to achieve continuous and uninterrupted brushing. This brushing method can effectively prevent the filter screen 664 from being clogged by attached impurities, thereby further improving the filtration efficiency. In addition, during the brushing process, the support rod 6656 can play an important role in assisting the support of the telescopic spring 6653, prompting the telescopic spring 6653 to stably drive the brush plate 6655 to brush and clean, thereby significantly improving the stability of the filtration process.

[0028] At the same time, during the use of the device, the rotation of the rotating shaft 661 can also drive the auger 69 at the bottom to rotate together. When the auger 69 rotates, on the one hand, it will fully stir the solution at the bottom of the tank body 2, and on the other hand, it will drive the solution to surge downward. At this time, the solution will flow back upward through the reflux pipe 7 during the downward flow. The reflux pipe 7 can transport the liquid from the bottom of the tank body 2 to the top of the tank body 2. On this basis, the electric heating coil at the bottom is started for heating operation, which can cause the solution inside the tank body 2 to form a dynamic cycle of up and down rolling during filtration. This circulation method can not only realize continuous circulation filtration and further improve the filtration effect, but also the up and down rolling of the solution can make the temperature evenly fill the interior of the tank body 2, thereby comprehensively improving the overall solid-liquid extraction effect of the device and ensuring that the device can achieve efficient, stable and high-quality working conditions during the treatment process. When the treatment is completed, the discharge valve can be opened and the treated material can be discharged through the discharge pipe.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
