Detailed Embodiments

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-5 , a composite fiber-reinforced corrosion-resistant screen device provided by the present utility model includes: a bottom plate 1, and further includes: a mounting frame 2 fixed to the top of the bottom plate 1, a central column 3 rotatably mounted on the outer wall of the top of the mounting frame 2, and an electric rotating table 4 mounted on the outer wall of the top of the bottom plate 1, the rotating member of the electric rotating table 4 is connected to the bottom of the central column 3, and mounting blocks 5 are fixed to the outer walls on both sides of the central column 3. Screen assemblies 6 are rotatably mounted on the outer walls on the opposite sides of the two mounting blocks 5. Through holes are opened at both ends of the outer wall of the top of the mounting frame 2, and limiting assemblies 7 are inserted into the two through holes. Turning assemblies 8 are mounted on both sides of the outer wall of the top of the bottom plate 1. A liquid outlet pipe 9 is mounted on one end of the outer wall of the top of the bottom plate 1, and a support plate 10 is mounted on the liquid outlet pipe 9. A liquid inlet pipe 11 is mounted on the top of the support plate 10, and a drain pipe 12 is fixed to the other end of the outer wall of the top of the bottom plate 1. A flushing assembly 13 is mounted on the drain pipe 12.

[0021] It should be noted here that: the two screen assemblies 6 provided can be used alternately. The chemical solution to be filtered can be introduced into one of the screen assemblies 6 located below it through the liquid inlet pipe 11 to filter the solution. The filtered solution is discharged through the liquid outlet pipe 9. When the impurities intercepted by this screen assembly 6 are relatively many and need to be turned over and flushed, the valve of the liquid inlet pipe 11 can be temporarily closed, and the central column 3 is driven to rotate 180° by the electric rotating table 4, so that the two screen assemblies 6 are interchanged. At this time, the valve of the liquid inlet pipe 11 is opened again to continue filtering the chemical solution. The screen assembly 6 will automatically turn over under the action of the turning assembly 8 during the rotation process. When the used screen assembly 6 is rotated to below the flushing assembly 13, it has already been turned over. At this time, the screen assembly 6 can be directly back-flushed by the flushing assembly 13 to wash away the impurities. The washed screen assembly 6 can be reserved for replacement next time. After the two screen assemblies 6 are transposed, the limiting assemblies 7 will respectively abut against the bottoms of the two screen assemblies 6, so that the two screen assemblies 6 remain stable during flushing or filtering.

[0022] In a preferred embodiment, the screen assembly 6 includes a driving rod 601, an arc-shaped groove 602 opened on the outer wall of the bottom of the driving rod 601, a circular tube 603 fixed to one end of the driving rod 601, a composite fiber mesh 604 installed on the inner wall of the circular tube 603, a driven rod 605 fixed to one end of the circular tube 603, and a gear 606 fixed to one end of the driven rod 605.

[0023] It should be noted here that the composite fiber mesh 604 can filter chemical solutions. When backwashing the composite fiber mesh 604 is required, the electric rotating table 4 can be driven to drive the central column 3 to rotate 180°. The circular tube 603 rotates together with the central column 3. During the rotation, the gear 606 contacts the flipping assembly 8, driving the driven rod 605 to rotate 180°, and further driving the circular tube 603 to rotate 180° to flip the composite fiber mesh 604, facilitating subsequent flushing.

[0024] In a preferred embodiment, the limiting assembly 7 includes a movable rod 701, a spring 702 sleeved outside the movable rod 701, and a top block 703 fixed to the top of the movable rod 701.

[0025] It should be noted here that when the active rod 601 rotates with the central column 3, the active rod 601 rotates to press the top block 703 downward, driving the movable rod 701 to descend and squeezing the spring 702. When the active rod 601 rotates to directly above the top block 703, the top block 703 is pushed into the arc-shaped groove 602 under the action of the spring 702, playing a certain limiting role on the active rod 601, so that the composite fiber mesh 604 remains stable during flushing or filtering.

[0026] In a preferred embodiment, the flipping assembly 8 includes a vertical plate 801 and an arc-shaped rack 802 fixed to the top of the vertical plate 801.

[0027] It should be noted here that during the rotation, the gear 606 contacts the arc-shaped rack 802, and under the action of the arc-shaped rack 802, the gear 606 rotates.

[0028] In a preferred embodiment, the flushing assembly 13 includes a support rod 1301, a water supply pipe 1302 fixed to the top of the support rod 1301, a cross pipe 1303 connected to the bottom of the water supply pipe 1302, and nozzles 1304 installed at the four corners of the bottom of the cross pipe 1303.

[0029] It should be noted here that water can enter the cross pipe 1303 through the water supply pipe 1302 and spray out from the nozzles 1304, spraying on the flipped composite fiber mesh 604 to perform backwashing on the composite fiber mesh 604.

[0030] In a preferred embodiment, the arc-shaped rack 802 has the same number of teeth as the gear 606.

[0031] It should be noted here that the gear 606 just rotates one full circle when rolling on the arc-shaped rack 802.

[0032] Working principle: Two provided composite fiber meshes 604 can be used alternately. The chemical solution to be filtered can be introduced into one of the composite fiber meshes 604 located below it through the liquid inlet pipe 11 for filtering the solution. The filtered solution is discharged through the liquid outlet pipe 9. When the impurities intercepted by this composite fiber mesh 604 are relatively numerous and it needs to be flipped and rinsed, the valve of the liquid inlet pipe 11 can be temporarily closed, and the central column 3 is driven to rotate 180° by the electric rotating table 4, so that the two composite fiber meshes 604 exchange positions. At this time, when the valve of the liquid inlet pipe 11 is opened again, the chemical solution can be continuously filtered. During the rotation of the composite fiber mesh 604, the gear 606 contacts the arc-shaped rack 802. Under the action of the arc-shaped rack 802, the gear 606 rotates, driving the driven rod 605 to rotate 180°, and further driving the round tube 603 to rotate 180° to flip the composite fiber mesh 604, facilitating subsequent rinsing. When the active rod 601 rotates with the central column 3, the active rod 601 rotates to press the top block 703 downward, driving the movable rod 701 to descend and squeezing the spring 702. When the active rod 601 rotates to the position directly above the top block 703, the top block 703 is pushed into the arc-shaped groove 602 under the action of the spring 702, playing a certain limiting role on the active rod 601, so that the composite fiber mesh 604 remains stable during rinsing or filtering, and can automatically perform displacement and flipping rinsing on the composite fiber mesh 604, which is safer and more convenient.
