Description

Technical Field

[0001] The present invention relates to the technical field of papermaking wastewater treatment, and specifically to a wastewater treatment device in the production of base paper. Background Art

[0002] In the process of papermaking industry production, wastewater discharge is a key link in environmental governance. Due to the characteristics of high suspended solid (SS) concentration, large chemical oxygen demand (COD) load, and poor biodegradability in papermaking wastewater, its treatment technology needs to take into account the dual requirements of physical separation and chemical treatment. The traditional sedimentation method has limited removal efficiency for fine fibers and colloidal substances, while the flotation method realizes the floating separation of pollutants by introducing microbubble carriers. Therefore, a wastewater treatment device is required to collect the foam and suspended solids floating on the water surface.

[0003] The authorized publication number CN118908334B discloses a wastewater treatment device in the production of base paper. This invention relates to the technical field of wastewater treatment, including a wastewater treatment tank, an arc-shaped collection cover that moves on one side of the top of the wastewater treatment tank to collect floating substances on the wastewater, and an adjustment frame for adjusting the angle of the arc-shaped collection cover. A fixed cylinder is fixedly installed at the center inside the wastewater treatment tank, a rotating column is coaxially arranged at the center of the fixed cylinder, a U-shaped fixing plate is welded and fixed on the outer periphery of one end of the top of the rotating column, two ends of the bottom of the U-shaped fixing plate are connected to a support plate through hydraulic telescopic pumps, and two ends of the bottom of the support plate are connected to a collection plate through rotating seats. This invention enables the arc-shaped collection cover to form different inclination angles with the water surface through the adjustment frame, achieving different degrees of slag scraping effects and realizing thorough slag scraping of floating substances. The arc-shaped collection cover is cleaned by spraying heads under the U-shaped fixing plate in cooperation with a cleaning storage tray, facilitating the arc-shaped collection cover to re-scrape the water surface. However, this invention collects floating foam and suspended solids through the arc-shaped collection cover. However, due to the large volume and light weight of the foam, the arc-shaped collection cover will be filled up in a very short time when collecting the foam. When the arc-shaped collection cover is filled up, it needs to be cleaned, which will greatly reduce the wastewater treatment efficiency. Moreover, when the arc-shaped collection cover is cleaned, the staff needs to rotate the storage tray to the bottom of the arc-shaped collection cover for collection, greatly increasing the wastewater treatment cost.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: a wastewater treatment device in the production of base paper.

[0016] 1. When the rotating column rotates, it can drive the rotating frame to rotate. When the rotating frame rotates, it can drive the floating foam collection component and the flocculent waste collection component to rotate respectively. When the floating foam collection component rotates, it can collect the foam on the water surface through components such as the foam suction port. When the flocculent waste collection component rotates, it can collect the flocculent waste floating under the water surface through components such as the flexible arc-shaped collection net, which is convenient for separate collection of the foam on the water surface and the flocs at the bottom of the water, thereby improving the collection efficiency. 2. When the mounting frame rotates, it can drive the fixing plate to rotate around the support column through the guide frame.

When the fixing plate moves up and down, it can drive the foam inlet pipe and the foam suction port to move up and down.

The cleaning brush can slide on the guide slide rail through the sliding groove during the threaded sliding. When the cleaning brush slides, it can clean the flocs on the flexible arc-shaped collection net. When the flocs on the flexible arc-shaped collection net are cleaned, the collection port opens to discharge and collect the cleaned flocs, which is convenient for quickly cleaning the flocs on the flexible arc-shaped collection net.

[0024] Please refer to Figure 1 and Figure 7, the present invention provides an embodiment: a wastewater treatment device in the production of base paper, including: a treatment tank 100, a support column 200 is fixedly installed at the center of the circle inside the treatment tank 100, a rotating column 300 is rotatably installed inside the support column 200 through a sealed bearing, a rotating assembly is installed at the bottom end of the rotating column 300, a rotating frame 400 is fixedly installed at the top end of the rotating column 300, a foam collecting assembly 500 for collecting foam on the water surface is installed on the rotating frame 400, and a flocculent waste collecting assembly 600 for collecting flocculent substances under the water surface is installed on the rotating frame 400; It should be understood that the wastewater during the production of base paper can be transported into the interior of the treatment tank 100 through an external pipeline. After the wastewater enters the interior of the treatment tank 100, a flocculant can be added and the wastewater can be aerated through an aeration device. A large amount of foam and flocculent substances will be generated after the wastewater is aerated. At this time, the rotating assembly (the rotating assembly is a relatively mature existing technology on the market, composed of components such as an electric motor) works to drive the rotating column 300 to rotate inside the support column 200. When the rotating column 300 rotates, it can drive the rotating frame 400 to rotate. When the rotating frame 400 rotates, it can drive the foam collecting assembly 500 and the flocculent waste collecting assembly 600 to rotate respectively. The foam collecting assembly 500 can collect the foam on the water surface, and when the flocculent waste collecting assembly 600 rotates, it can collect the flocculent waste floating under the water surface.

[0025] Such as Figure 1 and Figure 4 As shown, the rotating frame 400 includes a mounting frame 420 for installing the foam collecting assembly 500 and the flocculent waste collecting assembly 600, and the mounting frame 420 is arranged at the bottom of the rotating frame 400; It can be imagined that when the rotating frame 400 rotates, it can drive the mounting frame 420 to rotate through components. When the mounting frame 420 rotates, it can drive the foam collecting assembly 500 and the flocculent waste collecting assembly 600 to rotate. At the same time, the rotating frame 400 can drive the mounting frame 420 to lift through the work of components. When the mounting frame 420 lifts, it can drive the foam collecting assembly 500 and the flocculent waste collecting assembly 600 to perform lifting work.

[0026] Such as Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the foam collecting assembly 500 includes a foam suction port 510 for collecting foam, and a fixing plate 520 for adjusting the lifting of the foam suction port 510. A plurality of foam suction ports 510 are equidistantly arranged on the side surface of the mounting frame 420, and the fixing plate 520 is arranged at the top of the mounting frame 420; It should be noted that when the mounting frame 420 rotates, it drives several foam suction ports 510 to rotate through components. When the foam suction ports 510 rotate, suction is generated through the work of components to collect the foam floating on the water surface. At the same time, when the mounting frame 420 works, it drives the fixed plate 520 to lift and lower through the cooperation of components. When the fixed plate 520 lifts and lowers, the collection range of the foam suction ports 510 for foam can be increased.

[0027] As Figure 1 , Figures 3 - 6 and Figure 8 shown, the flocculent waste collection assembly 600 includes a flexible arc-shaped collection net 610 for collecting floccules under the water surface, and a recovery chamber 620 for recovering the floccules on the surface of the flexible arc-shaped collection net 610. The recovery chamber 620 is provided at the bottom of the mounting frame 420, and the flexible arc-shaped collection net 610 is provided inside the recovery chamber 620; It should be understood that when the mounting frame 420 rotates, it drives the flexible arc-shaped collection net 610 and the recovery chamber 620 to rotate respectively. When the flexible arc-shaped collection net 610 rotates, it can collect the floccules floating under the water surface. When the floccules inside the flexible arc-shaped collection net 610 are collected to a certain extent or for a certain period of time, at this time, the flexible arc-shaped collection net 610 rotates 180° through the cooperation of components. When the flexible arc-shaped collection net 610 rotates 180°, the flexible arc-shaped collection net 610 is bent through the cooperation of components, so that the side of the flexible arc-shaped collection net 610 for collecting floccules faces the inside of the recovery chamber 620. At this time, the recovery chamber 620 can clean the side of the flexible arc-shaped collection net 610 for collecting floccules through the work of components. At the same time, the other side of the flexible arc-shaped collection net 610 can also collect floccules, and the collected water flow will impact and clean the floccules on the back of the flexible arc-shaped collection net 610, improving the cleaning effect of the floccules.

[0028] As Figure 1 and Figure 4 shown, the rotating frame 400 includes a telescopic cylinder 410 for adjusting the height of the floating foam collection assembly 500 and the flocculent waste collection assembly 600, and a support pulley 430 for rotatably supporting the rotating frame 400. Four telescopic cylinders 410 are symmetrically installed in pairs at the bottom of the rotating frame 400, and the output end of the telescopic cylinder 410 is connected to the mounting frame 420. Support pulleys 430 are fixedly installed at both ends of the rotating frame 400, and the support pulleys 430 are slidably connected inside the groove at the top of the treatment tank 100; It can be conceived that when the rotating frame 400 rotates, it can drive the supporting pulleys 430 at both ends to rotate. When the supporting pulleys 430 rotate, they can slide in the grooves at the top of the treatment tank 100. When the foam collection assembly 500 and the flocculent waste collection assembly 600 need to adjust their heights, the telescopic cylinder 410 can work to push the mounting frame 420 to move. When the mounting frame 420 moves, it can drive the foam collection assembly 500 and the flocculent waste collection assembly 600 to lift and lower.

[0029] As Figure 2 and Figure 7 shown, the foam suction port 510 includes a foam inlet pipe 511 for transporting foam, and a connecting pipe 512 for collecting the foam inside the foam inlet pipe 511. The end of the foam suction port 510 is fixedly installed with the foam inlet pipe 511, and the other end of the foam inlet pipe 511 is provided with the connecting pipe 512; It should be understood that the foam suction port 510 can suck the foam into the inside of the foam inlet pipe 511, and the foam inlet pipe 511 can transport the foam into the inside of the connecting pipe 512.

[0030] As Figure 1 , Figure 2 , Figure 4 and Figure 7 shown, the foam suction port 510 further includes a support plate 513 for supporting and installing the connecting pipe 512, and a foam suction pump 514 for providing suction for the foam suction port 510. The outer surface of the connecting pipe 512 is fixedly installed with the support plate 513, and the bottom of the support plate 513 is fixedly connected to the mounting frame 420. The side of the connecting pipe 512 is connected to the input end of the foam suction pump 514 through a pipe. The bottom of the foam suction pump 514 is fixedly installed on the mounting frame 420, and the output end of the foam suction pump 514 is connected to the inside of the recycling device through a pipe; It can be conceived that when the mounting frame 420 rotates or lifts, it can drive the connecting pipe 512 to move through the support plate 513. When the connecting pipe 512 moves, it drives the foam suction port 510 to move. While the foam suction port 510 is moving, the foam suction pump 514 can work. When the foam suction pump 514 works, it will cause the foam suction port 510 to generate suction and transport the foam into the inside of the connecting pipe 512 through the foam inlet pipe 511. After the foam enters the connecting pipe 512, it can be discharged through the foam suction pump 514 into the recycling device through the pipe for collection.

[0031] As Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, the fixed plate 520 includes a connecting ring 521 for fixing the foam inlet pipe 511, a telescopic corrugated pipe 522 for connecting the foam inlet pipe 511 and the connecting pipe 512, and a guide frame 527 for limiting the fixed plate 520. A connecting ring 521 is fixedly installed on the outer surface of the foam inlet pipe 511. The outer surface of the connecting ring 521 is connected to the fixed plate 520 through a fixing rod. One end of the foam inlet pipe 511 is connected to one end of the telescopic corrugated pipe 522, and the other end of the telescopic corrugated pipe 522 is connected to the surface of the connecting pipe 512. The guide frame 527 is sleeved on the surface of the fixed plate 520, and the bottom of the guide frame 527 is fixedly installed on the mounting frame 420; It should be noted that when the fixed plate 520 moves up and down, it can slide within the guide frame 527. When the fixed plate 520 slides, it can drive the connecting ring 521 to move. When the connecting ring 521 moves, it can drive the foam inlet pipe 511 to move. When the foam inlet pipe 511 moves, it can drive the telescopic corrugated pipe 522 to move up and down, and the telescopic corrugated pipe 522 can also convey the foam.

[0032] As Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown in It should be understood that when the mounting frame 420 rotates, it can drive the fixed plate 520 to rotate through the guide frame 527. When the fixed plate 520 rotates, it can drive the guide post 523 to slide up and down within the annular wave groove 525. When the guide post 523 slides up and down, it can drive the fixed plate 520 to move up and down. When the mounting frame 420 moves up and down, it can drive the two annular lifting plates 524 to move through the connecting plate 526. When the first annular lifting plate 524 moves, it can slide vertically on the outer surface of the support column 200, and when the second annular lifting plate 524 moves, it can slide vertically on the inner wall of the treatment tank 100.

[0033] As Figures 3 - 6 and Figure 8As shown in the figure, the flexible arc-shaped collection net 610 includes a rotating rod 611 for the upper and lower edges of the flexible arc-shaped collection net 610 to rotate, a flexible connection strip 612 for protecting the left and right edges of the flexible arc-shaped collection net 610, and a fixing frame 613 for the flexible arc-shaped collection net 610 and the rotating rod 611 to rotate. Rotating rods 611 are fixedly connected to both the upper and lower edges of the flexible arc-shaped collection net 610. Both ends of the rotating rod 611 are rotatably connected to the fixing frame 613. Flexible connection strips 612 are fixedly connected to both the left and right edges of the flexible arc-shaped collection net 610; It can be imagined that when the flexible connection strips 612 on the left and right edges of the flexible arc-shaped collection net 610 are pulled by components, they can generate bending deformation. When the flexible connection strips 612 are bent, they can drive the flexible arc-shaped collection net 610 to bend. When the flexible arc-shaped collection net 610 bends, it can drive the rotating rods 611 on the upper and lower edges to rotate. When the rotating rods 611 rotate, their ends can rotate on the fixing frame 613.

[0034] As Figure 1 , Figures 3 - 6 and Figure 8 As shown in the figure, the flexible arc-shaped collection net 610 further includes a side collection net 614 for collecting flocs, and an operation groove 615, a sealing plate 616, a driving motor 617, a first threaded lead screw 618, a guide rod 619, an internally threaded moving plate 6110 for bending the flexible arc-shaped collection net 610, and a first driving motor 6111, a first sealing cover 6112, and a rotating rod 6113 for rotating the fixing frame 613. A side collection net 614 is fixedly installed on the fixing frame 613. An operation groove 615 is opened on the surface of the fixing frame 613 close to the flexible arc-shaped collection net 610. A sealing plate 616 is fixedly installed inside the operation groove 615. A driving motor 617 is fixedly installed at one end of the operation groove 615 close to the sealing plate 616. The output end of the driving motor 617 is fixedly installed with a first threaded lead screw 618. One end of the first threaded lead screw 618 passes through the sealing plate 616 and is connected to the other end of the operation groove 615. The surface of the first threaded lead screw 618 is threadedly connected with an internally threaded moving plate 6110. The outer surface of the internally threaded moving plate 6110 is movably connected to the guide rod 619 through a movable hole. Both ends of the guide rod 619 are respectively connected to the inner side of the operation groove 615 and the surface of the sealing plate 616. The output end of a first driving motor 6111 is connected to the center of the side of the fixing frame 613 close to the support column 200. The side of the first driving motor 6111 is sleeved with a first sealing cover 6112. One end of an installation frame 420 is fixedly installed on the outer surface of the first sealing cover 6112. A rotating rod 6113 is fixedly installed at the center of the side of the fixing frame 613 close to the treatment tank 100; It should be understood that when the first driving motor 6111 works, it can drive the fixing frame 613 at the output end to rotate. When the fixing frame 613 rotates, it can drive the fixing frame 613 at the other end to rotate through the rotating rod 611. When the fixing frame 613 at the other end rotates, it can drive the rotating rod 6113 to rotate. When the rotating rod 6113 rotates, it can rotate on the mounting frame 420. When the fixing frame 613 and the rotating rod 611 rotate, they can drive the flexible arc-shaped collecting net 610 to rotate. When the flexible arc-shaped collecting net 610 rotates 180°, the collecting side of the flexible arc-shaped collecting net 610 will face the inside of the recovery chamber 620. At this time, when the driving motor 617 works, it can drive the first threaded lead screw 618 to rotate. When the first threaded lead screw 618 rotates, it can drive the internally threaded moving plate 6110 to perform threaded sliding. When the internally threaded moving plate 6110 performs threaded sliding, it can slide on the guide rod 619. When the internally threaded moving plate 6110 slides, it can pull the flexible connecting strip 612. When the flexible connecting strip 612 is pulled, it will bend. When the flexible connecting strip 612 bends, it can drive the flexible arc-shaped collecting net 610 to bend. While the flexible connecting strip 612 bends, it can push the flocs on the side collecting net 614 into the inside of the recovery chamber 620, improving the collection efficiency.

[0035] As Figure 1 , Figures 3 - 6 and Figure 8 shown, the recovery chamber 620 includes a rotating groove 621 for the rotation of the fixing frame 613, an arc-shaped limiting plate 622 for limiting the flexible arc-shaped collecting net 610, and a mounting plate 623 for mounting the mounting frame 420, the first driving motor 6111, the first sealing cover 6112 and the rotating rod 6113. The rotating groove 621 is opened on the inner side of the recovery chamber 620. The arc-shaped limiting plate 622 is fixedly installed on the inner side of the recovery chamber 620 near the rotating groove 621. Mounting plates 623 are fixedly installed at both ends of the recovery chamber 620. The first driving motor 6111 and the first sealing cover 6112 are respectively fixedly installed on the surface of the mounting plate 623 near the center of the circle of the support column 200. The output end of the first driving motor 6111 passes through the surface of the mounting plate 623 and is connected to the fixing frame 613. One side of the mounting plate 623 close to the treatment tank 100 is connected to the mounting frame 420. The mounting plate 623 and the mounting frame 420 are rotationally connected with the rotating rod 6113 through an assembly groove; It can be imagined that when the fixing frame 613 rotates, it can rotate in the rotating groove 621. While the fixing frame 613 rotates, it can drive the rotating rod 6113 to rotate. When the rotating rod 6113 rotates, it can rotate inside the mounting plate 623. When the fixing frame 613 rotates 180°, the flexible connecting strip 612 and the flexible arc-shaped collecting net 610 can bend. When the flexible connecting strip 612 and the flexible arc-shaped collecting net 610 bend, the arc-shaped limiting plate 622 can be used for limiting.

[0036] As Figure 1 , Figures 3 - 8 shown, the recycling chamber 620 further includes a collection port 624 for recycling flocculent waste, and a second threaded lead screw 625, a guiding slide rail 626, a cleaning brush 627, a second driving motor 628 and a second sealing cover 629 for cleaning the flexible arc-shaped collection net 610. One end of the recycling chamber 620 close to the support column 200 is fixedly installed with the collection port 624. One end of the second threaded lead screw 625 is rotatably connected to the inner wall of the recycling chamber 620, and the other end of the second threaded lead screw 625 passes through the inner wall of the recycling chamber 620 and is connected to the output end of the second driving motor 628. The side of the second driving motor 628 is fixedly installed at one end of the recycling chamber 620. The second driving motor 628 is sleeved with the second sealing cover 629 on the side, and the side of the second sealing cover 629 is fixedly installed at one end of the recycling chamber 620. The side of the second threaded lead screw 625 is threadedly connected to the cleaning brush 627. The guiding slide rail 626 is fixedly installed on the inner wall of the recycling chamber 620. The side of the cleaning brush 627 is slidably connected to the guiding slide rail 626 through a chute; It should be noted that when the flexible connection strip 612 is in contact with the arc-shaped limiting plate 622, the second driving motor 628 can work. When the second driving motor 628 works, it can drive the second threaded lead screw 625 to rotate. When the second threaded lead screw 625 rotates, it can drive the cleaning brush 627 to perform threaded sliding. The cleaning brush 627 can slide on the guiding slide rail 626 through the chute during threaded sliding. When the cleaning brush 627 slides, it can clean the floccules on the flexible arc-shaped collection net 610. When the floccules on the flexible arc-shaped collection net 610 are cleaned, the collection port 624 is opened to discharge and collect the cleaned floccules.
