Description

Technical Field

[0001] This utility model belongs to the field of papermaking technology, and in particular relates to a papermaking wastewater sedimentation and recovery device. Background Technology

[0002] The paper production process generates a large amount of wastewater. In addition to harmful inorganic chemicals, the wastewater discharged from paper mills also contains volatile phenols, precipitated solids, suspended solids, lignin and other organic matter. After the wastewater is left to stand, a large amount of sediment will appear, which is also part of the wastewater from papermaking that needs to be treated.

[0003] To address this issue, Chinese Patent CN222694245U discloses a sedimentation and recovery device for papermaking wastewater. The sedimentation tank is equipped with an external lifting mechanism, which includes a lifting plate. Two support plates are fixed to the outer surface of the sedimentation tank. By using this lifting mechanism, after sedimentation, the drain pipe is opened to discharge the wastewater. Simultaneously, a hydraulic telescopic rod is controlled to drive the lifting plate and collection tray upwards. The filter screen at the bottom of the collection tray filters and separates the sediment inside. After the collection tray, carrying the sediment, rises to the top of the sedimentation tank, it is removed to collect the sediment. The collection tray is then reinstalled, and the hydraulic telescopic rod drives it down to the bottom of the sedimentation tank to drain the wastewater. After the wastewater in the sedimentation tank is drained, the drain pipe is closed, allowing for further sedimentation and recovery of the wastewater. This method is convenient and improves the device's efficiency.

[0004] However, the above-mentioned device collects sediment by raising and lowering the collection tray. When cleaning, the collection tray needs to be disassembled to manually clean the sediment inside, which is time-consuming and labor-intensive and affects work efficiency. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a papermaking wastewater sedimentation and recovery device, which has the advantages of convenient and timely collection and removal of sediments, as well as convenient automatic cleaning of sediments, saving time and labor, and effectively improving work efficiency. It solves the problem that in the prior art, sediments are collected by a collection tray that moves up and down, and during cleaning, the collection tray needs to be disassembled and the sediment inside needs to be manually cleaned, which is time-consuming, labor-intensive, and affects work efficiency.

[0006] This utility model is implemented as follows: a papermaking wastewater sedimentation and recovery device includes a sedimentation tank. A support frame is fixedly connected to the back of the sedimentation tank. Guide rods and lead screws are respectively provided at both ends of the support frame. A lifting frame is sleeved between the guide rods and lead screws. A rotary motor is fixedly installed at the top front end of the lifting frame. A stirring frame is fixedly installed at the output end of the rotary motor. A collection box is provided below the stirring frame. The back of the collection box is fixed to the bottom of the lifting frame by a support plate. The outer walls of the collection box can slide up and down along the inner wall of the sedimentation tank. A door panel is inserted into the open end of the front of the collection box. A pusher plate is slidably connected inside the collection box. Both ends of the pusher plate and the door panel are fixedly connected by sliding strips. A telescopic toothed plate is slidably installed between the pusher plate and the top right side of the door panel. When cleaning, the lower part of the lead screw can drive the telescopic toothed plate to move back and forth through a transmission belt, rotating rod and gear. The telescopic toothed plate can drive the pusher plate to move back and forth along the inside of the collection box.

[0007] In a preferred embodiment of this invention, the guide rod is fixedly connected to the support frame, the lead screw is connected to the support frame via a bearing, a stepper motor is fixedly installed at the bottom of the support frame, the output end of the stepper motor is fixedly connected to the lower end of the lead screw, one end of the lifting frame is slidably sleeved on the guide rod, and the other end of the lifting frame is threadedly sleeved on the threaded section of the lead screw. A baffle is fixedly connected to the upper ends of both the guide rod and the lead screw, and a first spring is fixedly connected between the baffle and the lifting frame, the first spring being sleeved on the guide rod.

[0008] With this setup, when the stepper motor drives the lead screw to rotate, the lifting frame can rise and fall stably under the guidance of the guide rod, ensuring that the collection box and stirring rack accurately reach the designated position. This facilitates the up and down movement of the collection box and stirring rack, making it easy for them to enter and leave the sedimentation tank, and is convenient to use. The baffle can prevent the lifting frame from rising excessively and falling off the guide rod and lead screw. The first spring can provide cushioning when the lifting frame descends, reducing impact, and at the same time assists in resetting when the lifting frame rises, improving the smoothness of the lifting process.

[0009] As a preferred embodiment of this invention, a slide rail is provided on the inner wall of the back of the sedimentation tank, and the support plate slides along the slide rail.

[0010] This design provides further guidance and support for the lifting and lowering of the collection box, effectively preventing the collection box from shaking or tilting during the lifting and lowering process. It ensures that the outer walls of the collection box always slide in close contact with the inner wall of the sedimentation tank, improving the stability of the lifting and lowering of the collection box and ensuring the reliability of sediment collection.

[0011] As a preferred embodiment of this utility model, the bottom of the collection box is provided with a grid-like structure, and a filter screen is fixed to the inner bottom of the collection box by bolts. Sliding grooves are provided on both sides of the inner wall of the collection box, and the slide bar slides along the corresponding sliding groove. A receiving groove is provided at the opening end of the collection box, and a second spring is provided in the receiving groove. The two ends of the second spring are respectively fixedly connected to the end of the receiving groove and the back of the door panel.

[0012] This design allows the grid-shaped bottom, combined with the filter screen, to efficiently filter wastewater and trap sediment. The filter screen is also easy to disassemble, clean, and replace, ensuring filtration efficiency. The combination of the slide groove and the slide bar allows the push plate and the door panel to slide smoothly. The second spring improves the stability of the synchronous movement of the push plate and the door panel, facilitating their elastic extension and retraction to automatically clean the sediment. When cleaning, the sediment can be automatically discharged from the opening of the collection box, making the operation flexible.

[0013] As a preferred embodiment of this utility model, a support block is fixedly connected to the top right side of both the push plate and the door panel, and a slide rod is fixedly connected to both ends of the telescopic toothed plate. The end of the slide rod slides through to the corresponding support block and is fixedly connected to a stop block. A third spring is fixedly connected between the stop block and the support block, and the third spring is sleeved on the slide rod.

[0014] This design facilitates stable installation of the telescopic toothed plate, allows for flexible telescopic movement of the plate in the left and right directions, and makes it easy to use.

[0015] In a preferred embodiment of this utility model, the toothed surface of the telescopic toothed plate abuts against a telescopic stop plate, an installation groove is provided on the right outer wall of the collection box, and limit grooves are provided on both sides of the installation groove. A limit plate is fixedly connected to the bottom of the telescopic stop plate, and the limit plate slides up and down along the installation groove. Both ends of the limit plate extend into the limit groove and slide along the limit groove. The limit plate and the bottom of the installation groove are fixedly connected by a fourth spring.

[0016] This design allows for flexible vertical movement of the telescopic stop plate. During sedimentation, the stop plate blocks the telescopic toothed plate, stretching the third spring and causing the toothed plate to press against the stop plate, maintaining the stability of the push plate and door panel. During cleaning, the stepper motor drives the lead screw to rotate, moving the lifting frame upwards. The collection box lifts the sediment out of the sedimentation tank until the lifting frame disengages from the threaded section of the lead screw, and the telescopic toothed plate aligns with the gear. At this point, pulling the stop plate downwards disengages it from the toothed plate, and the third spring resets the toothed plate, engaging it with the gear. This causes the rotating gear to move the toothed plate, which in turn moves the push plate and door panel synchronously until the sediment in the collection box is cleared and pushed out. This design saves time and effort, effectively improving work efficiency.

[0017] In a preferred embodiment of this invention, a rotating rod is connected to the right outer wall of the sedimentation tank via a bearing. A gear is fixedly fitted onto the top of the rotating rod. During cleaning, the gear meshes with the tooth surfaces of the telescopic tooth plate. A driven wheel is fixedly fitted onto the bottom of the rotating rod, and a driving wheel is fixedly fitted onto the lower part of the lead screw. The driving wheel and the driven wheel are connected by a transmission belt.

[0018] This design facilitates the engagement of gears and telescopic toothed plates, which in turn drive the pusher plate and door panel to move, enabling the collection box to open and the sediment to be pushed and swept clean.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the close cooperation of the lead screw, rotating rod, driving wheel, driven wheel, transmission belt, gear, telescopic toothed plate, telescopic stop plate, pusher plate, door panel, lifting frame and collection box, it can not only facilitate the timely collection and removal of sediment, but also facilitate the automatic cleaning of sediment, saving time and effort and effectively improving work efficiency.

[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] refer to Figures 1 to 5 As shown in the figure, an embodiment of the present invention provides a papermaking wastewater sedimentation and recovery device, including a sedimentation tank 1. A support frame 101 is fixedly connected to the back of the sedimentation tank 1. Guide rods 203 and lead screws 201 are respectively provided at both ends of the support frame 101. A lifting frame 2 is sleeved between the guide rods 203 and the lead screws 201. A rotary motor 301 is fixedly installed at the top front end of the lifting frame 2. A stirring frame 3 is fixedly installed at the output end of the rotary motor 301. A collection box 4 is provided below the stirring frame 3. The back of the collection box 4 is fixed to the bottom of the lifting frame 2 by a support plate 401. The outer walls of the collection box 4 can slide up and down along the inner wall of the sedimentation tank 1. A door panel 502 is inserted into the front opening of the collection box 4. A pusher plate 5 is slidably connected inside the collection box 4. The pusher plate 5 and the two ends of the door panel 502 are fixedly connected by a slide bar 501. A telescopic toothed plate 6 is slidably installed between the pusher plate 5 and the top right side of the door panel 502. When cleaning, the lower part of the screw 201 can drive the telescopic toothed plate 6 to move back and forth through the transmission belt 803, the rotating rod 8 and the gear 801. The telescopic toothed plate 6 can drive the pusher plate 5 to move back and forth along the inside of the collection box 4.

[0025] Specifically, the guide rod 203 is fixedly connected to the support frame 101, the lead screw 201 is connected to the support frame 101 through a bearing, a stepper motor 205 is fixedly installed at the bottom of the support frame 101, the output end of the stepper motor 205 is fixedly connected to the lower end of the lead screw 201, one end of the lifting frame 2 is slidably sleeved on the guide rod 203, and the other end of the lifting frame 2 is threadedly sleeved on the threaded section of the lead screw 201. A baffle 202 is fixedly connected to the upper ends of both the guide rod 203 and the lead screw 201, and a first spring 204 is fixedly connected between the baffle 202 and the lifting frame 2. The first spring 204 is sleeved on the guide rod 203.

[0026] Using the above scheme, when the stepper motor 205 drives the lead screw 201 to rotate, the lifting frame 2 can rise and fall stably under the guidance of the guide rod 203, ensuring that the collection box 4 and the stirring rack 3 accurately reach the designated position, which in turn facilitates the up and down movement of the collection box 4 and the stirring rack 3, making it convenient for them to enter and leave the sedimentation tank 1, and making it easy to use; the baffle 202 can prevent the lifting frame 2 from rising excessively and falling away from the guide rod 203 and the lead screw 201, and the first spring 204 can provide buffering when the lifting frame 2 descends, reducing impact, and at the same time assisting in the reset when the lifting frame 2 rises, improving the stability of the lifting process.

[0027] Specifically, a slide 102 is provided on the inner wall of the back side of the sedimentation tank 1, and the support plate 401 slides along the slide 102.

[0028] The above-mentioned scheme provides further guidance and support for the lifting and lowering of the collection box 4, effectively preventing the collection box 4 from shaking or tilting during the lifting and lowering process, ensuring that the outer walls of the collection box 4 always slide against the inner wall of the sedimentation tank 1, improving the stability of the lifting and lowering of the collection box 4, and ensuring the reliability of the sediment collection work.

[0029] Specifically, the bottom of the collection box 4 is arranged in a grid-like structure. A filter screen 404 is fixed to the inner bottom of the collection box 4 by bolts. Sliding grooves 402 are provided on both sides of the inner wall of the collection box 4. The sliding strip 501 slides along the corresponding sliding groove 402. A receiving groove 403 is provided at the opening end of the collection box 4. A second spring 503 is provided in the receiving groove 403. The two ends of the second spring 503 are fixedly connected to the end of the receiving groove 403 and the back of the door panel 502, respectively.

[0030] Using the above scheme, the grid-shaped bottom combined with the filter screen 404 can efficiently filter wastewater and trap sediment. The filter screen 404 is easy to disassemble, clean, and replace, ensuring the filtration effect. The cooperation between the slide groove 402 and the slide bar 501 makes the push plate 5 and the door plate 502 slide smoothly. The second spring 503 improves the stability of the synchronous movement of the push plate 5 and the door plate 502, and facilitates their elastic extension and retraction to automatically clean the sediment. When cleaning, the sediment can be automatically discharged from the opening end of the collection box 4, making the operation flexible.

[0031] Specifically, the pusher plate 5 and the top right side of the door panel 502 are both fixedly connected to a support block 604, and both ends of the telescopic toothed plate 6 are fixedly connected to a slide rod 601. The end of the slide rod 601 slides through to the corresponding support block 604 and is fixedly connected to a stop block 602. A third spring 603 is fixedly connected between the stop block 602 and the support block 604. The third spring 603 is sleeved on the slide rod 601.

[0032] The above scheme facilitates stable installation of the telescopic toothed plate 6, allows for flexible telescopic movement of the telescopic toothed plate 6 in the left and right directions, and makes it easy to use.

[0033] Specifically, the toothed surfaces of the telescopic toothed plate 6 are pressed against the telescopic stop plate 7. The outer right side wall of the collection box 4 is provided with an installation groove 405. Limiting grooves 406 are provided on both sides of the installation groove 405. A limiting plate 701 is fixedly connected to the bottom of the telescopic stop plate 7. The limiting plate 701 slides up and down along the installation groove 405. Both ends of the limiting plate 701 extend into the limiting grooves 406 and slide along the limiting grooves 406. The limiting plate 701 and the bottom of the installation groove 405 are fixedly connected by a fourth spring 702.

[0034] The above scheme facilitates the elastic extension and retraction of the telescopic stop plate 7 in the vertical direction. During sedimentation, the telescopic stop plate 7 blocks the telescopic toothed plate 6, and the third spring 603 is stretched, causing the telescopic toothed plate 6 to press against the telescopic stop plate 7, keeping the pusher plate 5 and the door panel 502 in a stable position. During cleaning, the stepper motor 205 drives the lead screw 201 to rotate, causing the lifting frame 2 to move upward. The collection box 4 carries the sediment upward and away from the sedimentation tank 1 until the lifting frame 2 disengages from the threaded section of the lead screw 201, and the telescopic toothed plate 6 aligns with the gear 801. At this point, pulling the telescopic stop plate 7 downward disengages it from the telescopic toothed plate 6, and the third spring 603 can drive the telescopic toothed plate 6 to reset and mesh with the gear 801. Then, the rotating gear 801 drives the telescopic toothed plate 6 to move, which in turn drives the pusher plate 5 and the door panel 502 to move synchronously until the sediment in the collection box 4 is cleaned and pushed out. This saves time and effort and effectively improves work efficiency.

[0035] Specifically, a rotating rod 8 is connected to the outer right side of the sedimentation tank 1 via a bearing. A gear 801 is fixedly sleeved on the top of the rotating rod 8. During cleaning, the gear 801 meshes with the tooth surface of the telescopic tooth plate 6. A driven wheel 802 is fixedly sleeved on the bottom of the rotating rod 8. A driving wheel 804 is fixedly sleeved on the lower part of the lead screw 201. The driving wheel 804 and the driven wheel 802 are connected by a transmission belt 803.

[0036] The above scheme facilitates the cooperation between gear 801 and telescopic toothed plate 6, which in turn drives pusher plate 5 and door plate 502 to move, thereby opening collection box 4 and cleaning sediment.

[0037] The working principle of this utility model: In use, first pour the papermaking wastewater and reagents into the sedimentation tank 1, start the rotary motor 301 to drive the stirring frame 3 to rotate, so that the reagents and wastewater react fully and improve the sedimentation efficiency. After sedimentation, the wastewater is discharged. When cleaning, start the stepper motor 205 to drive the lead screw 201 to rotate, so that the lifting frame 2 drives the stirring frame 3 and the collection box 4 to move upward until the collection box 4 carries the sediment away from the sedimentation tank 1, until the lifting frame 2 disengages from the threaded section of the lead screw 201, and the telescopic toothed plate 6 corresponds to the gear 801. At this time, pull down the telescopic stop plate 7 to disengage from the telescopic toothed plate 6, and the third spring 603 can drive the telescopic toothed plate 6 to reset and mesh with the gear 801. Then, the rotating gear 801 drives the telescopic toothed plate 6 to move, which in turn drives the pusher plate 5 and the door plate 502 to move synchronously until the sediment in the collection box 4 is cleaned out. This saves time and effort and effectively improves work efficiency.
