[0034] In related technologies, existing filtration equipment often requires manual removal of residual materials from the filtration equipment after filtration when processing ammonium tungstate solutions containing a lot of impurities. This is labor-intensive, places high demands on the physical strength of operators, and reduces the overall automation level and production efficiency.

[0035] The following is for reference. Figures 1-5 Describes a solution filtration device 1 according to an embodiment of the present invention.

[0036] like Figures 1-3As shown, the solution filtration device 1 according to this utility model includes a filter housing 11 and a stirring member 12, wherein a filtration channel is formed within the filter housing 11. The filtration channel provides the necessary space for solution flow and filtration. At least a portion of the stirring member 12 extends into the filtration channel, and the stirring member 12 is adapted to rotate to agitate the solution passing through the filtration channel. By effectively agitating the solution through rotation, the stirring member 12 promotes the uniform distribution of suspended solids in the solution, thereby improving the filtration efficiency.

[0037] The solution filtration device 1 also includes a filter screen 13 and a vibrating element 14. The filter screen 13 is disposed within the filtration channel and movably connected to the filter housing 11. The filter screen 13 is adapted to filter the solution passing through the filtration channel. The solution passes through the filter screen 13 as it passes through the filtration channel. Through the filtration action of the filter screen 13, solid impurities in the solution are effectively retained, while the remaining solution continues to flow, thus achieving filtration. The filter screen 13 is connected to the filter housing 11, allowing it to be installed within the filtration channel. The filter screen 13 can move relative to the filter housing 11, enabling it to vibrate within the filtration channel. The vibrating element 14 is connected to the filter screen 13 to drive the filter screen 13 to vibrate within the filtration channel. The vibrating element 14 drives the filter screen 13 to vibrate within the filter channel. The vibration loosens and removes impurities attached to the filter screen 13, promoting the removal of impurities from the filter screen 13, thus cleaning the filter screen 13, effectively preventing clogging, reducing the need for manual cleaning of the filter screen 13, and improving the level of automation and production efficiency.

[0038] Therefore, the solution filtration device 1 of this utility model, by setting the vibrating element 14, realizes automatic cleaning of the filter screen 13, effectively prevents clogging, reduces the need for manual cleaning, and improves the level of automation and production efficiency.

[0039] According to some embodiments of this utility model, such as Figure 2 and Figure 3As shown, the stirring element 12 is disposed on one side of the filter screen 13 in the thickness direction and spaced apart from the filter screen 13. The vibrating element 14 is disposed on the other side of the filter screen 13 in the thickness direction and is adapted to drive the filter screen 13 to vibrate in the thickness direction. This allows the stirring element 12 to fully stir the solution as it passes through the filtration channel, promoting the uniform distribution of suspended solids and thus improving filtration efficiency. Simultaneously, by driving the filter screen 13 to vibrate in the thickness direction, the vibrating element 14 effectively prevents impurities from accumulating on the surface of the filter screen 13, promotes impurity detachment, and achieves automatic cleaning of the filter screen 13, reducing the frequency of manual cleaning and improving the automation level and production efficiency of the equipment. The vibrating element 14, by driving the filter screen 13 to vibrate in the thickness direction, enhances the impurity removal effect on the surface of the filter screen 13 and also promotes the resuspension and dispersion of impurities in the solution inside and near the filter screen 13, further reducing the risk of clogging during the filtration process.

[0040] According to some embodiments of this utility model, such as Figure 3 and Figure 5 As shown, the inner wall of the filter housing 11 has a first groove 111 extending in the vibration direction; the solution filtration device 1 also includes a slider 112, which is movably disposed within the first groove 111 and connected to the filter screen 13. By setting the slider 112, when the filter screen 13 vibrates, it will drive the slider 112 to move within the first groove 111, so that the filter screen 13 can move smoothly along the first groove 111 in the vibration direction under the drive of the vibrating element 14, thereby achieving efficient vibration of the filter screen 13.

[0041] According to some embodiments of this utility model, such as Figure 5 As shown, the solution filtration device 1 also includes a first elastic element 113, which is disposed between the end wall of the first slide groove 111 and the slider 112. The first elastic element 113 is adapted to elastically deform in the vibration direction. By providing the first elastic element 113, the first elastic element 113 can effectively buffer the impact force when the filter screen 13 vibrates by elastically deforming in the vibration direction, so that the filter screen 13 can vibrate and move smoothly and efficiently along the first slide groove 111. At the same time, the first elastic element 113 can effectively constrain the vibration amplitude of the filter screen 13, optimize the uniformity of vibration, and enable the filter screen 13 to distribute and process suspended matter in the solution more evenly, further improving the filtration accuracy and efficiency.

[0042] According to some embodiments of this utility model, such as Figure 3 and Figure 4As shown, the vibrating element 14 includes a sleeve 141 and a transmission rod 142. The sleeve 141 is fixedly connected to the other side of the filter screen 13 in the thickness direction, and a second groove extending in the vibration direction is formed inside the sleeve 141. One end of the transmission rod 142 is movably disposed in the second groove, and the transmission rod 142 can move in the vibration direction to drive the filter screen 13 to vibrate in the thickness direction within the filter channel. When the transmission rod 142 moves to the end of the sleeve 141 in the vibration direction, it will impact the filter screen 13. Therefore, by reciprocating along the second groove, the transmission rod 142 can impact the filter screen 13 multiple times at different time points, thereby achieving the vibration of the filter screen 13 in the thickness direction.

[0043] The transmission rod 142, guided by the second slide groove, drives the filter screen 13 to vibrate in the thickness direction, thereby effectively preventing impurities from accumulating on the surface of the filter screen 13, promoting the shedding of impurities, and achieving automatic cleaning of the filter screen 13. The cooperation between the sleeve 141 and the transmission rod 142 not only enhances the driving stability and reliability of the vibrating element 14, but also optimizes the vibration effect of the filter screen 13.

[0044] According to some embodiments of this utility model, such as Figure 4 As shown, the vibrating element 14 also includes a crank spindle 143, which extends radially in the filter screen 13 and is rotatably disposed on the other side of the filter screen 13 in the thickness direction. The crank spindle 143 is formed with a cam 1431 extending radially in the crank spindle 143. The other end of the transmission rod 142 is connected to the eccentric position of the cam 1431. When the crank spindle 143 rotates, the cam 1431 drives the transmission rod 142 to reciprocate in the second slide groove, thereby driving the filter screen 13 to vibrate in the thickness direction in the filter channel.

[0045] Through the cooperation of the crankshaft 143 and the cam 1431, the rotational motion of the crankshaft 143 is converted into the linear reciprocating motion of the transmission rod 142, thereby achieving efficient vibration drive for the filter screen 13. The eccentric connection of the cam 1431 allows the transmission rod 142 to move back and forth regularly within the second slide groove, thereby driving the filter screen 13 to vibrate in the thickness direction, effectively preventing impurities from accumulating on the surface of the filter screen 13, promoting the shedding of impurities, and achieving automatic cleaning of the filter screen 13. The structure of the crankshaft 143 and the cam 1431 not only enhances the driving stability and reliability of the vibrating component 14, but also further optimizes the vibration effect of the filter screen 13, reducing the risk of filter screen 13 clogging.

[0046] According to some embodiments of this utility model, such as Figure 4As shown, the transmission rod 142 includes a striker 1421 and a connecting rod 1422. One end of the striker 1421 is slidably disposed in the second slide groove, and the other end of the striker 1421 is rotatably connected to one end of the connecting rod 1422. The other end of the connecting rod 1422 is connected to the eccentric position of the cam 1431. Through the cooperation of the striker 1421 and the connecting rod 1422, the rotational motion of the cam 1431 is converted into the linear reciprocating motion of the striker 1421 in the second slide groove, thereby achieving efficient vibration drive for the filter screen 13. The sliding arrangement of the striker 1421 ensures its smooth movement in the second slide groove, while the rotatable connection of the connecting rod 1422 allows the transmission rod 142 to flexibly adapt to the eccentric motion of the cam 1431.

[0047] According to some embodiments of this utility model, such as Figures 1-3 As shown, the solution filtration device 1 also includes a scraper, which is movably positioned at the end of the stirring element 12 in the vibration direction. The scraper is adapted to rotate under the drive of the stirring element 12 to scrape the surface of the filter screen 13. By providing the scraper, it can continuously scrape the surface of the filter screen 13 as the stirring element 12 rotates, thereby further removing impurities attached to the filter screen 13, preventing clogging, and enhancing the filtration effect. The scraper not only improves the cleaning efficiency of the filter screen 13 but also reduces the reliance on manual cleaning, improving the automation level and production efficiency of the equipment. Through the synergistic effect of the scraper and the stirring element 12, the solution filtration device 1 can achieve more thorough impurity removal during the filtration process, ensuring the continuity and high efficiency of the filtration process.

[0048] According to some embodiments of this utility model, such as Figures 1-3 As shown, the scraping element includes a rotating shaft 151 and scraping blades 152. The rotating shaft 151 is movably disposed at the end of the stirring element 12 in the vibration direction and extends toward the filter screen 13. The scraping blades 152 are disposed on the outer periphery of the rotating shaft 151 and are adapted to scrape the surface of the filter screen 13 as the rotating shaft 151 rotates. The scraping blades 152 can rotate under the drive of the stirring element 12, while continuously scraping the surface of the filter screen 13, effectively removing impurities attached to the filter screen 13, preventing clogging and enhancing the filtration effect. The mobility of the rotating shaft 151 ensures that the scraping blades 152 can adapt to the vibration of the filter screen 13, thereby achieving more thorough impurity removal during the filtration process.

[0049] Specifically, when the filter screen 13 moves upward, the rotating shaft 151 can move slightly upward along the vibration direction to keep the scraping blade 152 in close contact with the surface of the filter screen 13; similarly, when the filter screen 13 moves downward, the rotating shaft 151 can move slightly downward along the vibration direction to keep the scraping blade 152 in close contact with the surface of the filter screen 13.

[0050] According to some embodiments of this utility model, the end of the stirring member 12 is formed with a third groove recessed in the vibration direction, and the end of the rotating shaft 151 is movably disposed within the third groove. The rotating shaft 151 can move within the third groove along the vibration direction, thereby adapting to the vibration of the filter screen 13 and maintaining contact with the surface of the filter screen 13, ensuring that the scraping blade 152 can continuously and effectively scrape the surface of the filter screen 13. The setting of the third groove provides a stable motion trajectory for the rotating shaft 151, enhancing the working stability and reliability of the scraping member in a vibration environment, enabling the scraping member to efficiently remove impurities from the surface of the filter screen 13 under the drive of the stirring member 12.

[0051] According to some embodiments of this utility model, the solution filtration device 1 further includes a second elastic element. The second elastic element is disposed between the closed end of the third slide groove and one end of the rotating shaft 151 and is adapted to elastically deform in the vibration direction. This allows the second elastic element to provide elastic support when the filter screen 13 vibrates, buffering the movement of the rotating shaft 151 within the third slide groove, thereby ensuring that the scraping blade 152 maintains a stable contact pressure with the surface of the filter screen 13. The elastic deformation capability of the second elastic element enhances the adaptability and stability of the scraping element in a vibration environment, enabling the scraping element to work more smoothly during vibration.

[0052] According to some embodiments of this utility model, such as Figure 1 As shown, the solution filtration device 1 also includes a frame 16, a first driver 17, and a second driver 18. The frame 16 is connected to the filter housing 11. The first driver 17 is mounted on the frame 16 and connected to the stirring element 12, and is used to drive the stirring element 12 to rotate within the filtration channel. The second driver 18 is mounted on the frame 16 and connected to the vibrating element 14, and is used to drive the vibrating element 14 to vibrate the filter screen 13 within the filtration channel. Through the independent control of the first driver 17 and the second driver 18, the coordinated work of the stirring element 12 and the vibrating element 14 is realized. The rotation of the stirring element 12 promotes the uniform distribution of suspended matter in the solution and improves the filtration efficiency, while the vibration of the vibrating element 14 effectively prevents the filter screen 13 from clogging, promotes the shedding of impurities, and realizes automatic cleaning of the filter screen 13. The structure of the frame 16 provides stable support for the first driver 17, the second driver 18, and the filter housing 11, ensuring the reliability and stability of the equipment operation.

[0053] According to some embodiments of this utility model, such as Figures 1-3As shown, the stirring element 12 includes a stirring rod 121 and a stirring blade 122. One end of the stirring rod 121 is connected to the first actuator 17, and the other end of the stirring rod 121 extends into the filter channel. The stirring blade 122 is disposed on the outer periphery of the stirring rod 121 and located within the filter channel. The stirring blade 122 can rotate with the stirring rod 121 under the drive of the first actuator 17, thereby fully stirring the solution passing through the filter channel, promoting the uniform distribution of suspended solids in the solution, and improving filtration efficiency.

[0054] According to some embodiments of this utility model, such as Figure 1 As shown, the solution filtration device 1 also includes a support 19. One end of the support 19 is connected to the frame 16, and the other end of the support 19 forms a connecting portion 191. The connecting portion 191 is connected to the filter housing 11 and is constructed as an annular structure surrounding the outer periphery of the filter housing 11. The support 19 provides stable support and fixation for the filter housing 11, ensuring that the filter housing 11 remains stable during operation, while reducing the impact of vibration on the overall structure of the equipment. The annular structure of the connecting portion 191 not only enhances the connection strength between the support 19 and the filter housing 11, but also facilitates the installation and disassembly of the filter housing 11, simplifying the equipment maintenance process and making the overall structure of the solution filtration device 1 more stable and reliable.
