[0002] Acrylic resin is an important synthetic polymer material and is widely used in many fields. Acrylic resin is a high molecular polymer made by polymerization reaction of olefinic monomers such as acrylates and methacrylates. Its molecular structure contains various side chain groups derived from carbon-carbon double bonds. The type and number of these side chain groups determine the performance characteristics of acrylic resin. It has excellent light resistance and oxidation resistance, and is not prone to discoloration, powdering and cracking in long-term outdoor environments. It can provide long-term protection for coated objects.

[0010] The present invention provides an impurity filtering device in acrylic resin production, which has the following beneficial effects: 1. The impurity filtering device in the production of acrylic resin is provided with a rotating part, which drives the impact plate to rotate clockwise in the middle of the fixed frame through the top output end of the dual-axis motor, so that the impact plate impacts the acrylic resin solution after coarse filtration. Since there are still some impurities with smaller particle sizes that are difficult to be effectively intercepted after coarse filtration, when the solution is impacted, these fine impurity particles collide and aggregate with each other under the action of the impact force to form agglomerates with larger particle sizes. In the subsequent fine filtration process, these agglomerates with larger particle sizes are more easily intercepted by the fine filtration equipment, thereby significantly improving the removal efficiency of impurities and improving the purity of the final product. There may be some impurities in the acrylic resin that are wrapped by the resin. The impact effect can break this wrapping structure and expose the impurities originally wrapped in the resin. In the subsequent fine filtration, these exposed impurities can be more easily intercepted by the filter medium, further improving the degree of impurity removal and ensuring the quality stability of the product.

[0011] 2. The impurity filtering device in the production of acrylic resin is provided with a cleaning mechanism. The cleaning rod is driven by the output ends of the upper and lower ends of the double-axis motor and the connecting shaft at the same time. When the cleaning rod rotates clockwise in the inner cavity of the shell, the connecting shaft drives the cleaning rod to stir and impact the acrylic resin solution passing through the shell. At the same time, through the action of centrifugal force, the cleaning plate drives the rubber plate to move toward the inner wall of the shell through the connecting rod. By arranging a rubber plate on the side of the connecting plate, and the bending angle of the rubber plate is greater than that of the bent plate, when the cleaning rod rotates, the cleaning plate moves toward the inner wall of the shell by the action of centrifugal force, so that the rubber plate first collides with the inner wall of the shell, thereby avoiding collision damage between the bent plate and the inner wall of the shell. When the cleaning rod rotates, the bent plate can be offset against the inner wall of the shell by the action of centrifugal force, so that the cleaning rod can drive the bent plate to clean the inner wall of the shell.

[0012] 3. The impurity filtering device in the production of acrylic resin is provided with a collecting component. When the mesh plate filters the acrylic resin solution, a large amount of impurity particles screened out on the mesh plate will remain on the mesh plate, thereby interfering with the normal filtering work of the mesh plate. When the filtering is completed, the dual-axis motor is controlled so that the output end at the top of the dual-axis motor rotates counterclockwise, so that the impact mechanism squeezes and contacts the limit mechanism, so that the impurities of the acrylic resin solution remaining at the filtering point on the mesh plate enter the collecting shell for collection and storage.

[0013] 4. An impurity filtering device for the production of acrylic resin is provided with an impact mechanism. The upper connecting shaft drives the cleaning frame to rotate at the bottom of the mesh plate, so that the cleaning frame drives the rubber rod to rotate and clean the bottom of the mesh plate to avoid clogging of the mesh plate during filtering. At the same time, when the cleaning frame rotates, it drives the impact frame to rotate at the top of the mesh plate, so that the impact frame drives the arc plate to rotate and gather the impurities remaining on the top of the mesh plate, and gather the impurities to the middle of the arc plate. By arranging a circular arc plate on the inner side of the arc plate, the impurities gathered in the middle of the arc plate can be gathered and resisted, so as to avoid interfering with the normal filtering work of the mesh plate.

[0014] 5. An impurity filtering device for acrylic resin production is provided with a moving component. When the output end of the dual-axis motor drives the connecting shaft to rotate clockwise, the connecting shaft drives the arc plate to rotate through the impact frame, so that the arc plate drives the limit plate to rotate, so that the side of the limit plate and the side of the hook are squeezed, and when the hook is squeezed by the squeezing force of the limit plate when the limit plate rotates clockwise, the hook squeezes the arc frame, and the arc frame moves toward the moving plate through the sliding rod, so that when the limit plate rotates clockwise, the limit plate will not cause squeezing movement to the moving plate, thereby avoiding interference with the normal filtering work when the acrylic resin solution is filtered.

[0015] 6. An impurity filtering device for the production of acrylic resin is provided with an extrusion assembly. When the bent hook is in continuous extrusion contact with the limit plate, the bent hook passes through the arc frame and drives the movable plate to move in the sliding groove, so that the extrusion block is against the inner side of the extrusion plate through the circular groove. By opening a sliding groove on the inner side of the extrusion plate, and the sliding groove is arranged from high to low on the side close to the circular groove, when the bent hook passes through the arc frame and drives the movable plate to move in the sliding groove, and at the same time, when the extrusion block slides in the sliding groove, the extrusion block is subjected to the extrusion force of the inner wall of the sliding groove, so that the extrusion block drives the arc frame to move toward the movable plate through the sliding rod, so that the bent hook is separated from the extrusion between the limit plate, thereby avoiding interference with the normal rotation of the impact frame.

Since there are still some impurities with smaller particle sizes after the coarse filtration that are difficult to be effectively intercepted, when the solution is impacted, these fine impurity particles collide and aggregate with each other under the action of the impact force to form agglomerates with larger particle sizes.

[0021] Specific workflow: Start the delivery pump to deliver the pretreated acrylic resin solution to the feed pipe 5 of the filtering device at an appropriate flow rate and pressure. During the feeding process, it is necessary to control the flow rate and pressure of the solution to avoid damage to the filtering device caused by excessive flow rate or excessive pressure, thereby affecting the filtering effect. The solution first enters the coarse filtration stage. The solution coarsely filtered by the collecting component 3 at the top is continuously filtered and moved downward in the housing 1. The rotating component 4 rotates in the housing 1, thereby impacting the acrylic resin solution after coarse filtration, so that the impurity particles in the solution are agglomerated into larger particles. These large particles are more easily intercepted during fine filtration, thereby improving the filtration efficiency and making the filtered material purer. The solution through the rotating component 4 continues to move downward in the housing 1, so that the collecting component 3 at the bottom performs fine filtration on the acrylic resin solution after impact, and the filtered acrylic resin solution is discharged through the discharge pipe 6; When the acrylic resin solution enters the housing 1 through the feed pipe 5, the acrylic resin solution is coarsely filtered through the top collecting component 3. The acrylic resin solution after coarse filtration continues to flow downward in the inner cavity of the housing 1. By turning on the double-axis motor 45, the impact plate 43 is driven to rotate clockwise in the middle of the fixed frame 41 through the top output end of the double-axis motor 45, so that the impact plate 43 impacts the acrylic resin solution after coarse filtration. Since there are still some impurities with smaller particle sizes after coarse filtration that are difficult to be effectively intercepted, when the solution is impacted, these fine impurity particles collide with each other under the action of the impact force. , aggregate to form agglomerates with larger particle sizes. In the subsequent fine filtration process, these agglomerates with larger particle sizes are more easily intercepted by the fine filtration equipment, thereby significantly improving the impurity removal efficiency and improving the purity of the final product. The cleaning mechanism 47 is driven to rotate in the housing 1 through the output ends at the upper and lower ends of the dual-axis motor 45 and the connecting shaft 46, so that the cleaning mechanism 47 cleans the inner wall of the housing 1, thereby avoiding that when the acrylic resin solution is filtered, part of the acrylic resin solution will remain on the inner wall of the housing 1 when the acrylic resin solution passes through the inner wall of the housing 1, thereby being dried on the inner wall of the housing 1; Through the output ends of the upper and lower ends of the dual-axis motor 45, the cleaning rod 471 is driven by the connecting shaft 46 to rotate clockwise in the inner cavity of the shell 1. When the connecting shaft 46 drives the cleaning rod 471 to stir and impact the acrylic resin solution passing through the shell 1, the cleaning plate 475 drives the rubber plate 476 to move toward the inner wall of the shell 1 through the connecting rod 473 through the centrifugal force. By arranging the rubber plate 476 on the side of the connecting plate 472, and the bending angle of the rubber plate 476 is large, The cleaning rod 471 is rotated, and the cleaning plate 475 moves toward the inner wall of the housing 1 by the action of centrifugal force, so that the rubber plate 476 first collides with the inner wall of the housing 1, thereby avoiding the collision damage between the curved plate 477 and the inner wall of the housing 1. When the cleaning rod 471 rotates, the curved plate 477 can be abutted against the inner wall of the housing 1 by the action of centrifugal force, so that the cleaning rod 471 can drive the curved plate 477 to clean the inner wall of the housing 1; When the output end at the top of the dual-axis motor 45 rotates clockwise, the output end at the top of the dual-axis motor 45 drives the impact mechanism 34 to rotate at the top of the mesh plate 32 through the upper connecting shaft 46, so as to avoid that when the mesh plate 32 filters the acrylic resin solution, a large number of impurity particles screened out on the mesh plate 32 will remain on the mesh plate 32, thereby interfering with the normal filtering work of the mesh plate 32. When the filtering is finished, the dual-axis motor 45 is controlled so that the output end at the top of the dual-axis motor 45 rotates counterclockwise, so that the impact mechanism 34 squeezes and contacts the limit mechanism 35, so that the impurities of the acrylic resin solution remaining at the filtering position on the mesh plate 32 enter the collection shell 31 for collection and storage. When the output end at the top of the dual-axis motor 45 rotates clockwise, the output end at the top of the dual-axis motor 45 jointly drives the upper connecting shaft 46 to rotate, so that the upper connecting shaft 46 drives the cleaning frame 346 to rotate at the bottom of the mesh plate 32, so that the cleaning frame 346 drives the rubber rod 347 to rotate and clean the bottom of the mesh plate 32, so as to avoid clogging of the mesh plate 32 during filtering. At the same time, when the cleaning frame 346 rotates, it jointly drives the impact frame 341 to rotate at the top of the mesh plate 32, so that the impact frame 341 drives the arc plate 342 to rotate and gather the impurities remaining on the top of the mesh plate 32, and gather the impurities to the middle of the arc plate 342. By arranging the circular arc plate 345 on the inner side of the arc plate 342, the impurities gathered to the middle of the arc plate 342 are gathered and resisted, so as to avoid interfering with the normal filtering work of the mesh plate 32. After filtering the acrylic resin solution, the dual-axis motor 45 is controlled to drive the connecting shaft 46 to rotate counterclockwise through the output end of the dual-axis motor 45, so that the output end of the dual-axis motor 45 drives the cleaning frame 346 to rotate counterclockwise through the connecting shaft 46, so that the cleaning frame 346 drives the impact frame 341 to rotate counterclockwise on the top of the mesh plate 32, so that the impact frame 341 drives the limit plate 344 to squeeze and contact the moving component 353 through the arc plate 342, so that the moving component 353 moves in the sliding groove 351, and at the same time When the spring rod 354 is squeezed, the moving component 353 moves in the sliding groove 351, and the arc plate 342 is driven to rotate on the top of the mesh plate 32 through the impact frame 341, so that the arc plate 342 drives the impurities filtered out on the mesh plate 32 to move to the inner wall of the shell 1, and the impurities remaining on the mesh plate 32 are collected through the gap formed by the movement of the moving component 353 in the sliding groove 351, and enter the inner cavity of the collection shell 31 for collection, thereby avoiding a large amount of impurities remaining on the mesh plate 32, thereby interfering with the subsequent filtering work; When the output end of the dual-axis motor 45 drives the connecting shaft 46 to rotate clockwise, the connecting shaft 46 drives the arc plate 342 to rotate through the impact frame 341, so that the arc plate 342 drives the limiting plate 344 to rotate, so that the side of the limiting plate 344 and the side of the hook 3534 are squeezed, and when the hook 3534 is squeezed by the squeezing force of the limiting plate 344 when rotating clockwise, the hook 3534 squeezes the arc frame 3533, and the arc frame 3533 moves toward the moving plate 3531 through the sliding rod 3537, so that when the limiting plate 344 rotates clockwise, the limiting plate 344 will not squeeze and move the moving plate 3531, thereby avoiding interference with the normal filtering work when filtering the acrylic resin solution; When the output end of the dual-axis motor 45 drives the connecting shaft 46 to rotate counterclockwise, the connecting shaft 46 drives the arc plate 342 to rotate through the impact frame 341, so that the arc plate 342 drives the limit plate 344 to rotate, so that the arc surface of the limit plate 344 is squeezed with the arc surface of the hook 3534, and the hook 3534 is continuously squeezed and contacted with the limit plate 344, so that the hook 3534 drives the moving plate 3531 to move in the sliding groove 351 through the arc frame 3533, so that the arc plate 342 drives the impurities filtered out from the mesh plate 32 to be thrown into the inner cavity of the collecting shell 31 through the gap formed when the moving plate 3531 slides, so as to collect and process the impurities filtered out from the mesh plate 32, so as to avoid a large amount of impurities from accumulating on the top of the mesh plate 32 for a long time, thereby causing a phenomenon of drying and solidification, and thus interfering with the filtering work; When the hook 3534 is continuously pressed and contacted with the limiting plate 344, the hook 3534 passes through the arc frame 3533 to drive the movable plate 3531 to move in the sliding groove 351, so that the extrusion block 3536 is against the inner side of the extrusion plate 3521 through the circular groove 3522. By opening the sliding groove 3523 on the inner side of the extrusion plate 3521, and the side of the sliding groove 3523 close to the circular groove 3522 is arranged from high to low, the hook 3534 passes through the arc frame 35 33, when the movable plate 3531 is driven to move in the sliding groove 351, and at the same time, when the extrusion block 3536 slides in the sliding groove 3523, the extrusion block 3536 is subjected to the extrusion force of the inner wall of the sliding groove 351, so that the extrusion block 3536 drives the arc frame 3533 to move toward the movable plate 3531 through the sliding rod 3537, so that the curved hook 3534 is separated from the extrusion between the limiting plate 344, thereby avoiding interference with the normal rotation of the impact frame 341.
