Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage recycling system based on the production and manufacturing of seamless pipes. Background Art

[0002] At present, seamless pipe is a long steel strip with a hollow cross-section and no seams around it. The main production methods of seamless pipe are hot rolling, cold rolling, cold drawing, etc.

[0003] The wastewater generated during the production of seamless pipes contains a lot of impurities. The rolling, cutting and grinding of steel pipes will produce solid particles such as iron filings and iron oxide. In the production of seamless pipes, a large amount of lubricating oil and anti-rust oil are needed to reduce equipment wear and prevent steel pipes from rusting. These oils will enter the sewage circulation system with the sewage. The sewage circulation treatment system includes flocculation sedimentation, filtration, neutralization, membrane separation and other steps.

[0004] Sewage flocculates and settles in the sedimentation tank. The sediment needs to be drained and then removed manually, or a mechanical push plate can be moved at the bottom of the sedimentation tank to push the flocs and sediments to the cleaning port for centralized treatment. In the process of using a mechanical push plate for cleaning, the mechanical push plate must return to its original position after moving from one end of the sedimentation tank bottom to the other and then move again. The reciprocating motion of the mechanical push plate at the bottom of the tank disturbs the sediment and flocs at the bottom of the tank, resulting in low cleaning efficiency. Summary of the invention

[0005] In order to reduce the disturbance to the sediment at the bottom of the sedimentation tank and improve the cleaning efficiency of the mechanical push plate, the present application provides a sewage recycling system based on the production and manufacturing of seamless pipes.

[0006] The sewage recycling system based on seamless pipe production and manufacturing provided in this application adopts the following technical solutions: The sewage recycling system based on seamless pipe production and manufacturing includes a sedimentation tank, in which a mechanical push plate and a power assembly are arranged. The power assembly includes a screw and a motor. The screw passes through the mechanical push plate and is threadedly connected to the mechanical push plate. The screw is horizontally arranged and arranged along the length direction of the sedimentation tank. The motor drives the screw to rotate. The side wall of the mechanical push plate close to the length direction of the sedimentation tank abuts against the inner wall of the sedimentation tank. A lifting assembly is arranged in the sedimentation tank, and the lifting assembly is used for lifting and lowering the screw, the motor and the mechanical push plate.

[0007] By adopting the above technical solution, the motor provides power for the rotation of the screw, and the rotation of the screw drives the mechanical push plate to generate a rotation trend, but the two sides of the mechanical push plate are limited by the inner wall of the sedimentation tank, and finally the mechanical push plate moves along the length direction of the screw, and the mechanical push plate pushes the sediment at the bottom of the sedimentation tank from one end to the other end. At this time, the lifting assembly lifts the screw, the motor and the mechanical push plate, and the mechanical push plate is separated from the bottom of the sedimentation tank, and then the mechanical push plate returns. After returning to the original position, the lifting assembly lowers the mechanical push plate to the bottom of the sedimentation tank, and the mechanical push plate pushes the sediment at the bottom of the sedimentation tank again, and so on. During the resetting process, the mechanical push plate is separated from the bottom of the sedimentation tank, which reduces the disturbance to the sediment and improves the cleaning efficiency of the mechanical push plate.

[0008] Optionally, the lifting assembly includes a cage gear, a rack, a connecting rod, an electromagnet, a slider and a first spring, one end of the connecting rod is fixedly connected to one end of the screw, and the other end is fixedly connected to the output end of the motor; the rack is vertically fixed to the inner wall of the sedimentation tank; the connecting rod is hollow inside and a sliding hole is opened on the outer wall, the sliding hole is opened along the length direction of the connecting rod, the cage gear is ringed on the connecting rod, one end of the slider is fixed to the cage gear, and the other end passes through the sliding hole and extends into the interior of the connecting rod; the first spring and the electromagnet are both located inside the connecting rod and distributed on both sides of the slider, one end of the first spring is fixedly connected to the slider, and the other end is fixedly connected to the inner wall of the adjacent connecting rod end; the electromagnet is fixed to the inner wall of the connecting rod and is arranged opposite to the first spring, and the electromagnet cooperates with the first spring to engage or separate the cage gear and the rack.

[0009] By adopting the above technical solution, when the mechanical push plate needs to be lifted, the electromagnet cooperates with the first spring to mesh the cage gear with the rack. At this time, the electromagnet can magnetically adsorb the slider, and the first spring is in a rope pulling state, or the electromagnet is not powered, and the first spring is in a compressed state. Both of the above states can achieve the meshing of the cage gear and the rack. With the use of the motor, the cage gear rolls on the rack to achieve the lifting of the mechanical push plate. When the mechanical push plate needs to be lowered, the electromagnet is not powered, and the first spring pulls the slider away from the electromagnet, so that the cage gear and the rack can be separated. Alternatively, the electromagnet is powered to repel the slider, and the first spring is further compressed, which can also achieve the separation of the cage gear and the rack.

[0010] Optionally, when the electromagnet is energized, it repels the slider, at which time the first spring is in a compressed state, and the cage gear and the rack are in a separated state.

[0011] By adopting the above technical solution, the electromagnet and the slider repel each other, so that the separation state of the cage gear and the rack can be kept stable. At the same time, when the cage gear and the rack are engaged, the electromagnet is not energized and the first spring is in a compressed state, which can also ensure the stability of the engaged state.

[0012] Optionally, a slide groove is opened on the vertical inner wall of the sedimentation tank, the motor and the rack are both located in the slide groove, and the end of the screw away from the motor is slidably connected to the inner wall of the sedimentation tank, and the sliding direction is along the vertical direction.

[0013] By adopting the above technical solution, the opening of the slide groove defines a sliding path for the vertical movement of the motor and the screw, thereby ensuring the effective and stable movement of the motor.

[0014] Optionally, the mechanical push plate includes a horizontal plate, a vertical rod and a scraper. Two vertical rods are provided and are vertically distributed at both ends of the horizontal rod. The vertical rods are arranged perpendicular to the horizontal plate. The screw rods pass through the horizontal plate. The top of the vertical rod is fixedly connected to the horizontal plate, and the bottom of the vertical rod is fixedly connected to the scraper.

[0015] By adopting the above technical solution, the existence of the vertical rod extends the vertical distance between the scraper and the screw, so that when the scraper sinks to the bottom of the sedimentation tank, the screw can be as far away from the water surface or sediment as possible, ensuring that the cross plate moves smoothly on the screw.

[0016] Optionally, a rubber pad is fixed to the bottom of the scraper, and the rubber pad abuts against the bottom inner wall of the sedimentation tank.

[0017] By adopting the above technical solution, the presence of the rubber pad reduces the generation of gaps between the scraper and the bottom inner wall of the sedimentation tank, preventing flocs from entering the gaps and causing damage.

[0018] Optionally, the inner wall of the bottom of the sedimentation tank is composed of a straight section, an inclined section and a falling section in sequence along the direction away from the motor. The straight section is horizontal, and the inclined section is inclined upward in the direction away from the straight section. After the inclined section rises to the top, the falling section falls vertically to the same height as the straight section and then continues to extend in the direction away from the inclined section; the vertical rod is a telescopic rod.

[0019] By adopting the above technical solution, during the whole process of the scraper pushing the sediment, it first pushes horizontally, then pushes upward along the inclined section, and finally pushes the sediment into the space where the falling section is located, which is convenient for subsequent cleaning.

[0020] Optionally, a second spring is arranged in the vertical rod, and the second spring is used to push the scraper to move downward.

[0021] By adopting the above technical solution, when the scraper moves in the inclined section, the total length of the vertical rod is gradually shortened, the second spring is continuously compressed, and the force generated by the second spring is gradually increased, so that the rubber pad is more closely in contact with the bottom inner wall of the sedimentation tank.

[0022] Optionally, the sedimentation tank is provided with a sewage outlet and an oil outlet. The sewage outlet is located on the side wall of the sedimentation tank close to the falling section, and the oil outlet is located on the side wall of the sedimentation tank close to the motor, and the oil outlet is located below the motor.

[0023] By adopting the above technical solution, the sediment accumulated by the scraper is cleaned out of the sedimentation tank through the sewage outlet. When the scraper moves toward the motor, the bottom of the scraper is brought into contact with the liquid surface in the sedimentation tank, and the oil floating on the top of the sedimentation tank is pushed to the oil outlet by the scraper.

[0024] Optionally, an oil-absorbing felt is fixed on the inner wall of the sedimentation tank, and the oil-absorbing felt is located below the oil discharge port.

[0025] By adopting the above technical solution, when the scraper falls, the scraper rubs against the oil-absorbing felt, and the oil-absorbing felt wipes off the oil stains on the scraper.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The setting of the lifting assembly enables the mechanical push plate to be separated from the bottom of the sedimentation tank during the resetting process, reducing the disturbance of the sediment and improving the cleaning efficiency of the mechanical push plate; 2. During the return journey, the scraper scrapes the oily floating matter on the liquid surface in the sedimentation tank toward the oil discharge port; 3. The bottom shape of the sedimentation tank is designed to facilitate the cleaning of sediments, and also cooperates with the vertical rod and the second spring to make the rubber pad closely contact with the bottom of the sedimentation tank.

A mechanical push plate 2 and a power component 3 are arranged in the sedimentation tank 1. The power component 3 drives the mechanical push plate 2 to move back and forth along the length direction of the sedimentation tank 1. The mechanical push plate 2 pushes the sediment at the bottom of the sedimentation tank 1 together for easy cleaning.

[0032] refer to Figure 1 and Figure 2 The mechanical push plate 2 includes a horizontal plate 21, a vertical rod 22 and a scraper 23. Two vertical rods 22 are provided and are vertically distributed at both ends of the horizontal rod. The vertical rod 22 is arranged perpendicular to the horizontal plate 21. The top of the vertical rod 22 is fixedly connected to the horizontal plate 21. The bottom of the vertical rod 22 is fixedly connected to the scraper 23. The side wall of the scraper 23 close to the length direction of the sedimentation tank 1 abuts against the inner wall of the sedimentation tank 1. The power assembly 3 includes a screw 31 and a motor 32. The screw 31 penetrates the horizontal plate 21 and is threadedly connected to the horizontal plate 21. The screw 31 is arranged horizontally and along the length direction of the sedimentation tank 1. The motor 32 drives the screw 31 to rotate. A chute 6 is provided in the sedimentation tank 1. The chute 6 is provided in the vertical direction. The motor 32 is located in the chute 6 and slides along the length direction of the chute 6.

[0033] refer to Figures 2 to 6 A lifting assembly 4 is provided in the sedimentation tank 1.

One end is fixed to the cage gear 41, and the other end passes through the sliding hole 431 and extends into the interior of the connecting rod 43. The cage gear 41 slides on the connecting rod 43 and the sliding direction is in the direction of approaching or moving away from the rack 42; the first spring 46 and the electromagnet 44 are both located inside the connecting rod 43 and distributed on both sides of the slider 45. One end of the first spring 46 is fixedly connected to the slider 45, and the other end is fixedly connected to the inner wall of the end of the connecting rod 43 that is close to it; the electromagnet 44 is fixed on the inner wall of the connecting rod 43 and is arranged opposite to the first spring 46.

[0034] When the mechanical push plate 2 needs to be lifted, the electromagnet 44 cooperates with the first spring 46 to mesh the cage gear 41 with the rack 42. At this time, the electromagnet 44 is not energized, and the first spring 46 is in a compressed state. With the use of the motor 32, the cage gear 41 rolls on the rack 42 to lift the mechanical push plate 2. When the mechanical push plate 2 needs to be lowered, the electromagnet 44 is energized to repel the slider 45, and the first spring 46 is further compressed to separate the cage gear 41 from the rack 42. Whether the electromagnet 44 is energized or not belongs to the prior art and can be achieved by installing a battery and a wireless receiver, which will not be described in detail here.

[0035] refer to Figure 1 and Figure 4 The inner wall of the bottom of the sedimentation tank 1 is composed of a straight section 11, an inclined section 12 and a falling section 13 in the direction away from the motor 32. The straight section 11 is horizontal, and the inclined section 12 is inclined upward in the direction away from the straight section 11. After the inclined section 12 rises to the top, the falling section 13 falls vertically to the same height as the straight section 11 and then continues to extend in the direction away from the inclined section 12. The vertical rod 22 is a telescopic rod, and a second spring 7 is arranged in the telescopic rod. A rubber pad 5 is fixed at the bottom of the scraper 23, and the rubber pad 5 abuts against the inner wall of the bottom of the sedimentation tank 1.

The sewage outlet 14 is located on the side wall of the sedimentation tank 1 close to the falling section 13, and the oil outlet 15 is located on the side wall of the sedimentation tank 1 close to the motor 32. The oil outlet 15 is located below the motor 32. An oil absorption felt 16 is fixed on the inner wall of the sedimentation tank 1, and the oil absorption felt 16 is located below the oil outlet 15.

[0036] The implementation principle of the sewage recycling system based on seamless pipe production in the embodiment of the present application is as follows: the motor 32 provides power for the rotation of the screw 31, and the rotation of the screw 31 drives the mechanical push plate 2 to generate a rotation trend, but the two sides of the mechanical push plate 2 are limited by the inner wall of the sedimentation tank 1, and finally the mechanical push plate 2 moves along the length direction of the screw 31, and the mechanical push plate 2 pushes the sediment at the bottom of the sedimentation tank 1, and pushes it from the straight section 11 to the falling section 13. At this time, the lifting component 4 lifts the screw 31, the motor 32 and the mechanical push plate 2 The mechanical push plate 2 is lifted and separated from the bottom of the sedimentation tank 1, and then the mechanical push plate 2 returns. During the return process, the scraper 23 scrapes the oily floating objects on the liquid surface in the sedimentation tank 1 toward the oil discharge port 15. After the mechanical push plate 2 returns to its original position, the lifting assembly 4 lowers the mechanical push plate 2 to the bottom of the sedimentation tank 1, and the mechanical push plate 2 pushes the sediment at the bottom of the sedimentation tank 1 again, and so on. During the resetting process, the mechanical push plate 2 is separated from the bottom of the sedimentation tank 1, which reduces the disturbance to the sediment and improves the cleaning efficiency of the mechanical push plate 2.
