Description

Industrial sludge solid waste treatment into nutrient soil and its production process Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to the treatment of industrial sludge solid waste into nutrient soil and its production process. Background Technology

[0002] Sludge is a byproduct of industrial production processes such as sewage treatment plants or sand washing plants. It is mainly a mixture of water and mud. If this mud-water mixture is discharged directly without treatment, it will pollute the environment. Therefore, the recycling and treatment of sludge from industrial wastewater is of great significance. Industrial sludge contains a large amount of organic matter and inorganic salts. It can be processed to ferment industrial sludge into organic fertilizer. The organic fertilizer can then be mixed with soil to make nutrient soil, which not only reflects the concept of environmental protection but also achieves efficient utilization of waste.

[0003] However, when industrial sludge is discharged, it contains a large amount of impurities and industrial waste residue. These impurities and waste residue are not easy to crush and mix into the soil. Moreover, industrial waste residue is harmful and can easily affect the normal fertility of nutrient soil. In addition, the large amount of sludge makes it inconvenient to screen and remove impurities, resulting in low work efficiency. Therefore, this invention provides the treatment of industrial sludge solid waste into nutrient soil and its production process to meet people's needs. Summary of the Invention

[0031] According to the above technical solution, industrial sludge solid waste is treated into nutrient soil, which is prepared according to the production process of industrial sludge solid waste being treated into nutrient soil.

[0032] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0033] 1. Equipped with a convenient impurity removal mechanism, the drive motor drives the rotating rod and impurity removal grid to rotate continuously. The impurity removal grid screens the sludge entering the processing box to remove impurities. During the rotation, the impurity removal grid will intersect with the upper and lower intercepting grids, leaving the removed impurities and waste residue on the surface of the upper intercepting grid. This quickly removes waste residue from the sludge, preventing residue from being mixed in during the production of nutrient soil, which would prevent the nutrient soil from being properly crushed and would affect the composition ratio and nutritional characteristics of the nutrient soil. Impurity removal is performed during the sludge transportation process, and the operation is convenient.

[0034] At the same time, the rotating cam rotates together with the rotating rod. The rotating cam will intermittently contact and hit the drive bending plate. The buffer spring plays a shock absorption and buffering role, causing the drive bending rod and the fixed block to sway up and down, which in turn drives the rotating rod and the upper intercepting grid plate to sway. When the upper intercepting grid plate sways, it drives the impurities intercepted on its surface, making the impurities slide down more smoothly and preventing impurities from getting stuck on the upper intercepting grid plate and affecting the subsequent rotation of the impurity removal grid plate.

[0035] The drive wheel rotates along with the rotating rod, driving the driven wheel and drive gear to rotate. The drive gear meshes with the driven gear, causing the conveying roller to rotate. The sludge is intermittently conveyed through the conveying gap, making the sludge conveying process slower. This prevents the sludge from falling down too quickly, which would result in insufficient time for impurity removal and affect the normal impurity removal operation, causing incomplete impurity removal and leaving some impurities in the sludge.

[0036] 2. The incomplete gear rotates synchronously with the rotating rod, intermittently meshing with the moving rack, pushing it to move along the guide frame until its end contacts the contact button, activating the electric telescopic rod and electric push rod. The electric telescopic rod pushes the moving rack back to its original position, allowing it to continue meshing with the incomplete gear. The electric push rod drives the moving block forward, driving the cylinder to move in the middle of the swing rod, which pulls the swing rod to rotate. This causes the rotating rod, upper intercepting grid, and lower intercepting grid to rotate synchronously, causing the upper and lower intercepting grids to shift. This facilitates changing the tilt angle of the upper intercepting grid, allowing impurities on its surface to slide down and be discharged from the guide plate.

[0037] 3. Equipped with a pressurized drive mechanism, the pressurized air pump generates airflow, which is discharged into the feed channel through the hollow frame and air outlet. The pressurized gas is blown onto the surface of the sludge stored in the feed channel, which pushes the sludge and allows it to move smoothly downwards. This facilitates the conveying rollers to transport the sludge and prevents it from accumulating and becoming hollow or sticking to the inner wall of the feed channel, thus preventing it from sliding down properly and tightly. The pressurized gas is discharged along the inner wall of the feed channel, preventing the sludge from sticking to the inner wall of the feed channel and preventing the sludge from drying out and becoming dirty in the feed channel due to long-term adhesion.

[0038] The curved panel is attached to the surface of the sludge, and the position of the lifting rod corresponds to the volume of sludge in the feeding channel. The volume of residual sludge is monitored by the position of the lifting rod. After the sludge is consumed to a certain extent, the lifting rod descends, the contact plate contacts the pressure sensor, the hydraulic telescopic rod shortens, and the cover plate moves, opening the top of the feeding channel to facilitate the addition of sludge. When there is enough sludge in the feeding channel, the cover plate seals the top of the channel, which plays a role in sealing and preventing odors, preventing the sludge from being transported openly and causing odors to spread into the air and cause pollution.

[0039] 4. The lifting rod is guided by the connecting rod and guide groove. As the lifting rod moves with the cover plate, the moving block slides inside the guide groove. The connecting spring limits the position of the connecting rod. The height of the lifting rod changes with the height of the connecting rod. When sludge is added, the lifting rod is lifted by the connecting rod, so that the lifting rod always stays at the top of the sludge when the sludge is gradually added. This prevents the sludge from covering the curved panel when it is injected, which would prevent it from adhering to the sludge surface. Both ends of the curved panel are arc-shaped, so it will not insert into the sludge when it is moving.

[0040] In summary, by combining a convenient impurity removal mechanism and a pressurized drive mechanism, the cover plate seals the top of the feed channel, preventing sludge and foreign matter from being released at will. The protective door covers one end of the processing box, which plays a sealing role during sludge impurity removal and prevents the odor of sludge from escaping from inside the processing box. When removing impurities from the surface of the upper intercepting grid, the upper intercepting grid is pushed to rotate by the moving block and the drive cylinder. The connecting rod moves forward with the moving block, and the connecting column moves inside the movable groove. The connecting rod pushes the protective door to rotate and open the protective door, allowing impurities to flow into the collection box along the guide plate. The door is only opened when impurities are discharged, preventing the sludge from being exposed for a long time and causing its odor to be released quickly.

[0041] Simultaneously, a portion of the airflow generated by the pressurized air pump is injected into the gas distribution box through the three-way connector and exhaust pipe. The airflow is discharged downwards, cleaning the inner wall of the transparent observation plate. The staff can use the transparent observation plate to easily observe the work inside the treatment box. The sludge solution adheres to the inner wall of the transparent observation plate. The airflow continuously blows towards the inner wall of the transparent observation plate, which plays a role in cleaning and keeping it clean. After the upper intercepting grid plate rotates, it is kept at a certain angle. A portion of the airflow blows towards its tilted surface, which has a pushing effect on the impurities on its surface.

When the upper intercepting grid 605 sways, it drives the impurities intercepted on its surface, making the impurities slide down more smoothly and preventing impurities from getting stuck on the upper intercepting grid 605 and affecting the rotation of the subsequent impurity removal grid 602.

[0069] The drive wheel 607 rotates together with the rotating rod 601, driving the driven wheel 609 and the drive gear 610 to rotate. The drive gear 610 meshes with the driven gear 614, causing the conveying roller 612 to rotate. The conveying notch 613 is used to intermittently convey the sludge, making the sludge conveying process slower. This prevents the sludge from falling down too quickly, which would result in insufficient time for impurity removal and affect the normal impurity removal operation, causing incomplete impurity removal and leaving some impurities in the sludge.

[0070] Two symmetrical swing rods 631 are fixedly mounted on both ends of the rotating rod 604. Electric push rods 632 are fixedly mounted on both ends of the surface of the processing box 4 above the swing rods 631. The moving rack 618 is located directly below the incomplete gear 616. The signal output terminal of the contact button 621 is connected to the signal input terminals of the electric telescopic rod 622 and the electric push rod 632. A moving block 633 is fixedly connected to the end of the electric push rod 632. A driving cylinder 634 is fixedly connected to one end of the middle of the moving block 633. A connecting rod 635 is fixedly connected to the top of the processing box 3. A protective door 636 is hinged to the middle of the processing box 4, away from the inclined channel 2. A transparent observation plate 637 is embedded in the middle of the protective door 636. Connecting columns 638 are symmetrically fixed at both ends of the bottom of the transparent observation plate 637. A movable groove 639 is opened in the middle of the bottom of each of the two connecting rods 635. A long groove is opened in the middle of the swing rod 631. A driving cylinder 634 moves through the long groove, and the connecting column 638 moves through the movable groove 639. 9. A collection box 640 is fixedly installed at one end of the bottom of the processing box 4, below the protective door 636. A guide plate 641 is fixedly installed at one end of the processing box 4, corresponding to the collection box 640. An incomplete gear 616 rotates synchronously with the rotating rod 601, intermittently meshing with the moving rack 618, pushing it to move along the guide frame 617 until its end contacts the contact button 621, activating the electric telescopic rod 622 and the electric push rod 632. The electric telescopic rod 622 will then push the moving rack 632... Strip 618 returns to its original position, allowing it to continue meshing with the incomplete gear 616. Meanwhile, the electric push rod 632 drives the moving block 633 to move, which in turn drives the cylinder 634 to move in the middle of the swing rod 631. This causes the swing rod 631 to rotate, which in turn causes the rotating rod 604, the upper intercepting grid 605, and the lower intercepting grid 606 to rotate synchronously. This causes the upper and lower intercepting grids 605 and 606 to shift, making it easier to change the tilt angle of the upper intercepting grid 605 so that impurities on its surface can slide down and be discharged from the guide plate 641.

[0071] A pressure drive mechanism 7 is installed at the top of the feed channel 3;

A pressurizing air pump 703 is fixedly installed at one end of the middle of the feeding channel 3. A three-way connector 704 is fixedly connected to the air outlet of the pressurizing air pump 703. An air supply pipe 705 is fixedly connected to the top of the three-way connector 704. One end of the air supply pipe 705 is connected to the hollow square frame 701. Air outlet holes 706 are equidistantly opened on the bottom edge of the hollow square frame 701.

[0074] A mounting base 707 is fixedly installed at one end of the feeding channel 3. Hydraulic telescopic rods 708 are symmetrically installed at both ends of the top of the mounting base 707. A guide cylinder 709 is fixedly installed through one end of the cover plate 702. A lifting rod 710 is movably installed in the middle of the guide cylinder 709. A mounting block 711 is fixedly connected to the top of the lifting rod 710. A movable locking block 712 is fixedly installed on the top of the mounting block 711. A curved panel 713 is installed at the bottom of the lifting rod 710. A connecting rod 714 is rotatably installed in the middle of the top of the mounting base 707. A guide groove 714 is opened at the bottom of the connecting rod 714. 15. Two hydraulic telescopic rods 708 are respectively connected to the two sides of the cover plate 702. The movable locking block 712 is movably locked inside the guide groove 715. One end of the connecting spring 717 is connected to the top of the connecting rod 714. A fixed vertical plate 716 is fixedly installed on the top of the mounting base 707 at one side of the connecting rod 714. One end of the fixed vertical plate 716 is fixedly connected to the connecting spring 717. One end of the mounting block 711 is fixedly connected to the contact plate 718. A pressure sensor 719 is fixedly installed on the top of the cover plate 702 at one side of the guide cylinder 709. 718 is located directly above pressure sensor 719. The signal output terminal of pressure sensor 719 is connected to the signal input terminal of hydraulic telescopic rod 708. One end of three-way connector 704 is fixedly connected to exhaust pipe 720. A gas diversion box 721 is fixedly installed at the top of one end inside processing box 4. One end of exhaust pipe 720 is connected to one end of gas diversion box 721. Gas diversion box 721 is located directly above guide inclined plate 641. The bottom of gas diversion box 721 is inclined towards the inner wall of protective door 636. Air blowing holes are equidistantly opened at the inclined bottom end of gas diversion box 721. The pressurized air pump 703 generates airflow, which is discharged into the feed channel 3 through the hollow frame 701 and the air outlet 706. The pressurized gas blows towards the surface of the sludge stored inside the feed channel 3, which pushes the sludge so that it can move smoothly downwards. This facilitates the conveying roller 612 to transport the sludge, preventing it from accumulating and becoming hollow or sticking to the inner wall of the feed channel 3 and failing to slide down properly. The pressurized gas is discharged along the inner wall of the feed channel 3, so that the sludge does not stick to the inner wall of the feed channel 3 and prevents the sludge from drying out due to long-term adhesion, which would make the feed channel 3 dirty.

[0075] The curved panel 713 is attached to the surface of the sludge, and the position of the lifting rod 710 corresponds to the volume of sludge in the feed channel 3. The volume of residual sludge is monitored by the position of the lifting rod 710. After the sludge is consumed to a certain extent, the lifting rod 710 descends, the contact plate 718 contacts the pressure sensor 719, the hydraulic telescopic rod 708 shortens, and the cover plate 702 moves, opening the top of the feed channel 3 to facilitate the addition of sludge. When there is enough sludge inside the feed channel 3, the cover plate 702 seals and covers the top of the channel, which plays a role in sealing and preventing odors, preventing the sludge from being transported openly and causing odors to spread into the air and cause pollution.

[0076] The lifting rod 710 is guided by the connecting rod 714 and the guide groove 715. When the lifting rod 710 moves with the cover plate 702, the moving block 712 slides inside the guide groove 715. The connecting spring 717 limits the position of the connecting rod 714. When the lifting rod 710 moves, its height changes with the height of the connecting rod 714. When sludge is added, the lifting rod 710 is lifted by the connecting rod 714, so that the lifting rod 710 always stays at the top of the sludge when the sludge is gradually added. This prevents the sludge from covering the curved panel 713 when it is injected, which would prevent it from adhering to the sludge surface. Both ends of the curved panel 713 are arc-shaped, so it will not insert into the sludge when it moves to adhere to the sludge.

[0077] The working principle and usage process of this invention are as follows: First, the hydraulic telescopic rod 708 retracts, driving the cover plate 702 to move. The moving block 712 always slides inside the guide groove 715. The lifting rod 710 moves forward along the connecting rod 714. The connecting spring 717 provides limiting support for the connecting rod 714. When the lifting rod 710 moves away from the connecting spring 717, the pressure on it is greater, causing the connecting spring 717 to be stretched. Meanwhile, the connecting rod 714 deflects and tilts downward. The lifting rod 710 gradually moves closer to the connecting spring 717, reducing its pressure. The connecting spring 717 shortens, lifting the connecting rod 714 upward, causing the lifting rod 710 to rise and rise to a certain height to meet the curved panel 713. At this point, the cover plate 702 no longer completely covers the top of the feed channel 3. The workers pour the industrial sludge, which contains industrial impurities and waste residue, into the feed channel 3. Some of it enters the inclined channel 2 and is blocked by the conveying roller 612 inside. The height of the sludge stored in the feed channel 3 gradually increases until it adheres to the bottom of the curved panel 713. The injection of sludge stops, the hydraulic telescopic rod 708 extends, and the cover plate 702 seals the top of the feed channel 3, so that the sludge is not exposed to the air and causes odor and pollution. Both ends of the curved panel 713 are arc-shaped and slide against the surface of the sludge without inserting into the sludge. The sludge level is relatively high. When the lifting rod 710 moves, it will keep the connecting rod 714 raised, so that the connecting spring 717 will not be compressed and stretched.

[0078] Then, the drive motor 603 starts, driving the rotating rod 601 to rotate. The driving wheel 607 and the driven wheel 609 are connected by a transmission belt 611 and both rotate with the rotating rod 601. The driving gear 610 and the driven gear 614 mesh with each other, and the driven gear 614 and the conveying roller 612 rotate synchronously. The sludge enters the conveying gap 613 and is intermittently conveyed to the inside of the processing box 4 through the inclined channel 2 during the rotation of the conveying roller 612. The conveying process is smooth to prevent the sludge from being directly dumped and unable to be processed smoothly. The pressurized air pump 703 continuously generates pressurized gas, which is discharged through the hollow frame 701 and blown onto the surface of the sludge, which pressurizes and pushes the sludge. During the continuous conveying of the sludge, it is pushed to descend smoothly, and the impurity removal grid 602 rotates accordingly. When rod 601 rotates, it passes through the interior of the sludge, screening the impurities and waste inside the sludge. The sludge is fine, and the impurities cannot pass through the impurity removal grid 602. They are driven upward by the impurity removal grid 602. As the impurity removal grid 602 and the upper intercepting grid 605 gradually intersect, large particles of impurities are intercepted by the upper intercepting grid 605. As the impurity removal grid 602 and the upper intercepting grid 605 continue to intersect, the impurities intercepted at the top of the upper intercepting grid 605 gradually slide down under the joint pressure of the impurity removal grid 602 and the upper intercepting grid 605. The impurities are lubricated by the sludge adhering to their outside, preventing the impurities from causing blockage to the impurity removal grid 602 and the upper intercepting grid 605. The impurity removal grid 602 then passes through the lower intercepting grid 606 and is inserted into the sludge for screening and impurity removal.

[0079] Both the rotating cam 615 and the incomplete gear 616 rotate together with the rotating rod 601. The rotating cam 615 impacts the driving bend plate 630 once per revolution. The driving bend plate 630 is impacted, and the buffer spring 626 provides cushioning protection. The guide rod 625 guides the fixed block 624, causing the driving bend plate 630, the fixed block 624, and the rotating rod 604 to sway up and down. The rotating rod 604 carries the upper intercepting grid plate 605 along with it, allowing the intercepted impurities to slide down smoothly and preventing them from remaining on the surface of the upper intercepting grid plate 605. Furthermore, some of the airflow generated by the pressurized air pump 703... The gas is injected into the gas distribution box 721 through the three-way connector 704 and the exhaust pipe 720. The airflow is discharged from the bottom of the gas distribution box 721 and blows upward to the surface of the intercepting grid 605, blowing away the impurities on its surface and causing them to slide down quickly and fall onto the surface of the guide inclined plate 641. The protective door 636 plays a sealing and protective role, preventing impurities from being discharged. The inside of the treatment box 4 is also kept sealed, preventing the odor of the sludge from being discharged. The treated sludge is discharged downward through the discharge channel 5 into the subsequent treatment equipment. The subsequent equipment processes the impurity-removed sludge multiple times to make nutrient soil, realizing the reuse of sludge.

[0080] At the same time, the incomplete gear 616 will mesh with the moving rack 618. Each time the incomplete gear 616 rotates, it meshes with the moving rack 618 to a certain extent, pushing it forward a certain distance along the guide frame 617 until one end of the moving rack 618 contacts the contact button 621, which activates the electric telescopic rod 622 and the electric push rod 632. The protrusion 619 and the mating block 623 are mated together. The electric telescopic rod 622 will drive the moving rack 618 back to its original position, which will facilitate the subsequent meshing of the incomplete gear 616 with it.

[0081] When the electric push rod 632 retracts, it moves the moving block 633, driving the cylinder 634 to continuously move through the swing rod 631. This causes the swing rod 631 and the rotating rod 604 to rotate, changing the tilt angle of the upper intercepting grid 605 to make it closer to a vertical plane, facilitating the dripping of sludge from its surface. The gas discharged from the gas diversion box 721 accelerates the sludge's descent, preventing sludge and residue from adhering to the surface of the upper intercepting grid 605 and preventing the subsequent impurity removal grid 602 from passing through properly. The lower intercepting grid 606 shifts to the original position of the upper intercepting grid 605, and the lower intercepting grid 606 intersects with the impurity removal grid 602 to intercept the screened impurities. Meanwhile, the connecting bent rod 635 moves accordingly. When block 633 moves, connecting column 638 is located inside movable groove 639. When it moves, it pushes protective door 636, causing it to flip upward and unfold its bottom, so that impurities inside guide plate 641 can slide down and be discharged. Sludge sliding down upper intercepting grid 605 is also discharged along guide plate 641. Then, electric push rod 632 extends, moving block 633 moves forward back to its original position, and rotating rod 604 rotates in the opposite direction again, so that upper intercepting grid 605 and lower intercepting grid 606 return to their original positions. Impurities intercepted on the surface of lower intercepting grid 606 will be poured into sludge at the bottom of treatment box 4, which can be screened out later. Protective door 636 also closes to treatment box 4 again for sealing protection.

[0082] As the sludge inside the feed channel 3 continues to decrease, the curved panel 713 remains in contact with the surface of the sludge, and the height of the stored sludge decreases. As the curved panel 713 descends, the connecting spring 717 is stretched, and the connecting rod 714 gradually tilts until the contact plate 718 presses against the top of the pressure sensor 719. The hydraulic telescopic rod 708 drives the cover plate 702 to move, exposing the top of the feed channel 3, allowing the operator to add sludge inside.
