[0013] A method for using a fiber interception filter device for papermaking wastewater, comprising the following steps:

[0014] S1: When using the equipment, the external water pipe is connected with the top of the shell in a penetrating manner, and it is ensured that the top water flow is limited by the impurity pipe, two water flows are formed, and are in contact with the top of the rotating frame;

[0015] S2: The impact force of the falling water acts on the top of the rotating frame, and forces the rotating frame to rotate downward with the outer wall of the rotating column as the center point, at this time the distance between the supporting frame and the rotating frame is reduced, and the extension spring is compressed and shrunk;

[0016] S3: The downward movement of the rotating frame breaks through the top of the rotating frame, and the rotating frame and the material blocking slide form a hook, the sewage part penetrates the gap between the rotating frame and the supporting frame, and the fiber long impurities are affected by the hook formed by the rotating frame and the material blocking slide and stay on the top of the supporting frame.

[0017] The present application has the following beneficial effects:

[0018] (1) The present application utilizes the impact force of water flow from top to bottom, and sets supporting frames and rotating frames in the equipment, when using the equipment, the external water pipe is connected with the top of the shell in a penetrating manner, and it is ensured that the top water flow is limited by the impurity pipe, two water flows are formed, and are in contact with the top of the rotating frame, in this process, the impact force of the falling water acts on the top of the rotating frame, and forces the rotating frame to rotate downward with the outer wall of the rotating column as the center point, at this time the distance between the supporting frame and the rotating frame is reduced, and the extension spring is compressed and shrunk, and with the downward movement of the rotating frame, the material blocking slide breaks through the top of the rotating frame, and the rotating frame and the material blocking slide form a hook, as shown in the figure Figure FourIn the state shown, in the falling wastewater, the sewage part will penetrate the gap of the rotating frame and the support frame, and the fiber long impurities will be affected by the hook formed by the rotating frame and the material blocking slide plate and stay on the top of the support frame, and after mixing with water, the fiber impurities will have certain viscosity, and the fiber impurities will be attached to the top of the rotating frame. By applying the above components, most of the fibers in the wastewater are collected to avoid the blockage of the equipment caused by the fibers.

[0019] (2) The water flow impacts the rotating frame, and the force received by the rotating frame is transmitted to the rotating column through the extension spring, so that the rotating column rotates, the rotating column drives the gear disc to rotate through the gear ring, and the gear disc drives the cross frame to rotate through the support column, wherein the cross frame and the support frame form a cross state, and the rotating directions of the cross frame and the support frame are opposite under the influence of the gear ring and the gear disc. The fiber impurities are sticky on the surface of the rotating frame due to the viscosity caused by water, and at this time the cross frame passes through the gap of the support frame and drives the impurities to separate from the surface of the support frame. In addition, the rotating column drives the support frame and the rotating frame to rotate around the rotating column during rotation, and when the support frame and the rotating frame fall off the water flow, the pressure received by the rotating frame decreases, the extension spring releases mechanical power, and the distance between the support frame and the rotating frame is forced to expand. The protruding part of the material blocking slide plate will be collected in the rotating frame. By applying the above components, the sticky fibers in the equipment are effectively removed, and the impurity removal efficiency of the equipment is improved.

[0020] (3) The gear disc rotates regularly, and a driving block and a U-shaped rod are arranged in the equipment. When the gear disc rotates, the driving block drives the U-shaped rod to slide regularly along the outer wall of the mounting plate, and the U-shaped rod drives the tooth bar to move through the pushing block. When the tooth bar moves left and right, it will present a state as shown in the figure. Figure Ten When the tooth bar moves to the right, the gear ring two rotates counterclockwise, and at this time the side surface of the pressure block contacts the side surface of the rotating plate and forces the rotating plate to rotate around the outer surface of the fixed column. At this time, the gear ring two cannot drive the fixed column and the rotating cylinder to rotate. When the tooth bar moves to the right, the gear ring two rotates counterclockwise, and at this time the pressure block contacts the other side of the rotating plate. The rotating plate is limited by the limiting square plate, and at this time the pressure block drives the fixed column and the rotating cylinder to rotate through the rotating plate. The rotating cylinder drives a plurality of cleaning rods to clean the surface of the filter screen. By applying the above components, the short fibers that cannot be hooked by the rotating frame are avoided, and the hole of the filter screen is prevented from being blocked.

[0021] (4) The present application utilizes the regular cleaning of the filter screen surface by the cleaning rod, and sets a cleaning ring and a limiting wheel inside the equipment. When the cleaning rod rotates to clean, the fibers falling on the top of the filter screen are removed, and finally discharged into the inside of the impurity pipe through the impurity inlet. The horizontal height of the limiting wheel is higher than the highest point of the impurity inlet. When the rotating cylinder rotates, the cleaning rod will pass through the impurity inlet to the top of the filter screen. In this process, the limiting wheel will contact with the inner wall of the impurity pipe. With the continuous rotation of the cleaning rod, the limiting wheel will force the cleaning ring to move along the outer wall of the cleaning rod, so that the cleaning ring forms a state as shown in Figure Nine With the one-way rotation of the rotating cylinder, the cleaning rod outside the impurity pipe will return to the inside of the impurity pipe again. At this time, the limiting wheel loses the limitation of the inner wall of the impurity pipe, and the spring telescopic rod releases the mechanical power, so that the limiting wheel and the cleaning ring move outward along the outer wall of the cleaning rod to remove the small fibers adhered to the surface of the cleaning rod. In addition, the inclined sliding rod moves downward along the through hole of the L-shaped rod under the action of the pulling spring and enters the next tooth gap of the tooth ring two when the tooth ring two rotates counterclockwise. After the tooth ring two completes the rotation, the vertical surface of the inclined sliding rod contacts with the outer surface of the limiting square plate, so that the thrust generated in the contraction process of the spring telescopic rod does not cause the clockwise rotation of the cleaning rod.

Through the application of the above components, most of the fibers in the wastewater are collected, and the fiber is prevented from causing internal blockage of the equipment.

[0043] In the embodiment two, please refer to Figure 5 Figure 12 On the basis of the first embodiment, the discharging mechanism 2 further comprises a support column 201 rotatably connected to the inner wall of the mounting plate 102, a cross frame 202 fixedly connected to the side wall of the support column 201, a gear disc 203 fixedly connected to the side wall of the cross frame 202, a tooth ring one 204 fixedly connected to the side wall of the rotating column 104, a driving block 205 fixedly connected to the side wall of the gear disc 203, a U-shaped rod 206 slidably connected to the side wall of the mounting plate 102, and the outer wall of the driving block 205 is slidably connected to the inner wall of the U-shaped rod 206.

The cross frame 202 and the support frame 105 form a cross state, and the rotation directions of the cross frame 202 and the support frame 105 are opposite due to the influence of the tooth ring one 204 and the gear disc 203. The fiber impurities will be adhered to the surface of the rotating frame 106 due to the viscosity caused by water, and at this time the cross frame 202 passes through the gap of the support frame 105 and drives the impurities to separate from the surface of the support frame 105.

[0044] The discharging mechanism 2 further comprises a pushing block 207 fixedly connected to the side wall of the U-shaped rod 206, and a tooth rod 208 fixedly connected to the side wall of the pushing block 207.

When the support frame 105 and the rotating frame 106 are separated from the water flow, the pressure received by the rotating frame 106 is reduced, the extension spring 110 releases mechanical power, and the distance between the support frame 105 and the rotating frame 106 is expanded. The protruding part of the material blocking slide plate 109 will be collected in the rotating frame 106. Through the application of the above components, the fiber adhered in the equipment is effectively removed, and the impurity removal efficiency of the equipment is improved.

[0045] ​The limiting mechanism 3 further comprises a spring telescopic rod 304 fixedly connected to the top of the rotating cylinder 210, an outer wall of the cleaning rod 211 is slidingly connected with a cleaning ring 305, the top of the cleaning ring 305 is rotatably connected with a limiting wheel 306, the bottom of the rotating cylinder 210 is rotatably connected with a tooth ring two 307, the outer wall of the tooth ring two 307 is meshingly connected with the outer wall of the tooth rod 208, by virtue of the regular cleaning feature of the cleaning rod 211 on the surface of the filter screen 107, the cleaning ring 305 and the limiting wheel 306 are arranged inside the device, when the cleaning rod 211 rotates to clean, the fibers falling on the top of the filter screen 107 are removed and finally discharged into the inside of the impurity pipe 103 through the impurity inlet 111, wherein the horizontal height of the limiting wheel 306 is higher than the highest point of the impurity inlet 111, when the rotating cylinder 210 rotates, the cleaning rod 211 will reach the top of the filter screen 107 through the impurity inlet 111, in this process, the limiting wheel 306 will be in contact with the inner wall of the impurity pipe 103, with the continuous rotation of the cleaning rod 211, the limiting wheel 306 will force the cleaning ring 305 to move along the outer wall of the cleaning rod 211, so that the cleaning ring 305 forms a state as shown in Figure Nine with the one-way rotation of the rotating cylinder 210, the cleaning rod 211 outside the impurity pipe 103 will return to the inside of the impurity pipe 103 again, at this time, the limiting wheel 306 loses the limitation of the inner wall of the impurity pipe 103, the spring telescopic rod 304 will release the mechanical power, so that the limiting wheel 306 and the cleaning ring 305 move outward along the outer wall of the cleaning rod 211 to remove the small fibers adhered to the surface of the cleaning rod 211, so as to avoid that the small fibers adhere to the surface of the cleaning rod 211 after being wetted, which affects the subsequent cleaning effect of the cleaning rod 211; in addition, during use, when the tooth ring two 307 rotates counterclockwise, the tooth gap of the tooth ring two 307 will be in contact with the slope of the slope sliding rod 302, so as to force the slope sliding rod 302 to move downward along the through hole of the L-shaped rod 301, and under the action of pulling the spring 303, the slope sliding rod 302 enters the next tooth gap of the tooth ring two 307, after the tooth ring two 307 completes the rotation, the vertical surface of the slope sliding rod 302 will be in contact with the outer surface of the limiting square plate 309, so as to avoid that the pushing force generated during the contraction of the spring telescopic rod 304 causes the cleaning rod 211 to rotate clockwise.

[0046] The limiting mechanism 3 also includes a fixed column 308 fixedly connected to the bottom of the rotating cylinder 210. A limiting square plate 309 is fixedly connected to the side wall of the fixed column 308, and a rotating plate 310 is rotatably connected to the inner wall of the fixed column 308. Several pressure blocks 311 are fixedly connected to the inner wall of the gear ring 207. Taking advantage of the regular rotation of the gear disk 203, a driving block 205 and a U-shaped rod 206 are provided inside the equipment. When the gear disk 203 rotates, the driving block 205 will drive the U-shaped rod 206 to slide regularly along the outer wall of the mounting plate 102. At the same time, the U-shaped rod 206 drives the rack 208 to move through the pushing block 207. When the rack 208 moves laterally left and right, it will present the following... Figure Ten As shown, when the rack 208 moves laterally to the left, the second gear ring 307 will rotate clockwise. At this time, the side of the pressure block 311 contacts the side of the rotating plate 310, forcing the rotating plate 310 to rotate around the outer surface of the fixed column 308. At this time, the second gear ring 307 will not be able to drive the fixed column 308 and the rotating cylinder 210 to rotate. When the rack 208 moves laterally to the right, the second gear ring 307 will rotate counterclockwise. At this time, the pressure block 311 will contact the other side of the rotating plate 310. The rotating plate 310 is restricted by the limiting plate 309. At this time, the pressure block 311 will drive the fixed column 308 and the rotating cylinder 210 to rotate through the rotating plate 310. The rotating cylinder 210 drives several cleaning rods 211 to clean the surface of the filter screen 107. Through the application of the above components, it is avoided that shorter fibers cannot be hooked by the rotating frame 106, causing the holes of the filter screen 107 to become blocked.

[0047] The filtration method of this filtration device includes the following steps:

[0048] S1: When using the equipment, connect the external water pipe to the top of the outer casing 101 and ensure that the water flow at the top is restricted by the impurity pipe 103, forming two water flows that contact the top of the rotating frame 106.

[0049] S2: The impact force from the water drop will act on the top of the rotating frame 106, and force the rotating frame 106 to rotate downward with the outer wall of the rotating column 104 as the center point. At this time, the distance between the support frame 105 and the rotating frame 106 will decrease, and the telescopic spring 110 will be compressed and contracted.

[0050] S3: As the rotating frame 106 moves downward, the baffle plate 109 will break through the top of the rotating frame 106, so that the rotating frame 106 and the baffle plate 109 form a hook and fall into the wastewater. The sewage will penetrate the gap between the rotating frame 106 and the support frame 105, while the long fibrous impurities will be affected by the hook formed by the rotating frame 106 and the baffle plate 109 and stay on the top of the support frame 105.

[0051] One specific application of the embodiment is: when using the device, the external water pipe is connected with the top of the shell 101, and the top water flow is limited by the impurity pipe 103, forming two water flows, and contacting the top of the rotating frame 106. In this process, the impact force of the falling is applied to the top of the rotating frame 106, and the rotating frame 106 is forced to rotate downward with the outer wall of the rotating column 104 as the center. At this time, the distance between the supporting frame 105 and the rotating frame 106 is reduced, and the extension spring 110 is compressed and shrunk. With the downward movement of the rotating frame 106, the material blocking slide plate 109 will break through the top of the rotating frame 106, so that the rotating frame 106 and the material blocking slide plate 109 form a hook, and the state shown in Figure Four The sewage part in the falling wastewater will penetrate the gap between the rotating frame 106 and the supporting frame 105, and the fiber-like long impurities will be affected by the hook formed by the rotating frame 106 and the material blocking slide plate 109 and stay on the top of the supporting frame 105. After the fiber-like impurities are mixed with water, a certain viscosity will be generated, and the fiber impurities will be attached to the top of the rotating frame 106.

[0052] The water flow impacts the rotating frame 106, and the force received by the rotating frame 106 is transmitted to the rotating column 104 through the extension spring 110, so that the rotating column 104 rotates. The rotating column 104 drives the gear disc 203 to rotate through the gear ring one 204, and the gear disc 203 drives the cross frame 202 to rotate through the support column 201. The cross frame 202 and the supporting frame 105 form a cross state, and the rotating direction of the cross frame 202 and the supporting frame 105 is opposite due to the influence of the gear ring one 204 and the gear disc 203. The fiber impurities will be attached to the surface of the rotating frame 106 due to the viscosity caused by water, and at this time the cross frame 202 penetrates the gap between the supporting frame 105 and drives the impurities to separate from the surface of the supporting frame 105. In addition, the rotating column 104 drives the supporting frame 105 and the rotating frame 106 to rotate with the rotating column 104 as the center during the rotating process. When the supporting frame 105 and the rotating frame 106 fall off the water flow, the pressure received by the rotating frame 106 decreases, the extension spring 110 releases the mechanical power, and the distance between the supporting frame 105 and the rotating frame 106 is expanded. The protruding part of the material blocking slide plate 109 will be collected inside the rotating frame 106. Through the application of the above components, the fiber adhered in the device is effectively removed, and the impurity removal efficiency of the device is improved. The driving block 205 and the U-shaped rod 206 are arranged inside the device by using the regular rotation characteristics of the gear disc 203. When the gear disc 203 rotates, the driving block 205 drives the U-shaped rod 206 to slide regularly along the outer wall of the mounting plate 102. At the same time, the U-shaped rod 206 drives the tooth rod 208 to move through the pushing block 207. When the tooth rod 208 moves left and right, it will present a state as shown in Figure TenThe state shown, when the tooth bar 208 is transversely moved to the left, the tooth ring two 307 will generate clockwise rotation, at this time the side of the pressure block 311 is in contact with the side of the rotating plate 310, and forces the rotating plate 310 to generate rotation with the outer surface of the fixed column 308 as the center, at this time the tooth ring two 307 will not be able to drive the fixed column 308 and the rotating cylinder 210 to rotate, when the tooth bar 208 is transversely moved to the right, the tooth ring two 307 generates counterclockwise rotation, at this time the pressure block 311 will be in contact with the other side of the rotating plate 310, and the rotating plate 310 is limited by the limiting square plate 309, at this time the pressure block 311 will drive the fixed column 308 and the rotating cylinder 210 to rotate through the rotating plate 310, and the rotating cylinder 210 drives several cleaning rods 211 to clean the surface of the filter screen 107, through the application of the above components, it avoids that the shorter fibers cannot be hooked by the rotating frame 106, causing the hole of the filter screen 107 to be blocked.

[0053] By using the above-mentioned cleaning rod 211 to regularly clean the surface of the filter screen 107, a cleaning ring 305 and a limiting wheel 306 are arranged inside the device, when the cleaning rod 211 rotates and cleans, the fibers falling on the top of the filter screen 107 are removed, and finally discharged into the inside of the impurity pipe 103 through the impurity inlet 111, wherein the horizontal height of the limiting wheel 306 is higher than the highest point of the impurity inlet 111, when the rotating cylinder 210 rotates, the cleaning rod 211 will reach the top of the filter screen 107 through the impurity inlet 111, in this process, the limiting wheel 306 will be in contact with the inner wall of the impurity pipe 103, as the cleaning rod 211 continues to rotate, the limiting wheel 306 will force the cleaning ring 305 to move along the outer wall of the cleaning rod 211, so that the cleaning ring 305 forms a state as shown in Figure Nine With the one-way rotation of the rotating cylinder 210, the cleaning rod 211 outside the impurity pipe 103 will return to the inside of the impurity pipe 103 again, at this time the limiting wheel 306 loses the limitation of the inner wall of the impurity pipe 103, the spring telescopic rod 304 will release the mechanical power, so that the limiting wheel 306 and the cleaning ring 305 move outward along the outer wall of the cleaning rod 211, to remove the small fibers adhered to the surface of the cleaning rod 211, so as to avoid that the small fibers adhere to the surface of the cleaning rod 211 after being wetted, which affects the subsequent cleaning effect of the cleaning rod 211; in addition, the inclined sliding rod 302 will move downward along the through hole of the L-shaped rod 301 under the action of the pulling spring 303 and enter the next tooth gap of the tooth ring two 307 when the tooth ring two 307 rotates counterclockwise, the vertical surface of the inclined sliding rod 302 will be in contact with the outer surface of the limiting square plate 309 after the tooth ring two 307 completes the rotation, so as to avoid that the pushing force generated in the contraction process of the spring telescopic rod 304 causes the cleaning rod 211 to rotate clockwise.
