Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a wastewater treatment device for needle coke production. Background Technology

[0002] The production of needle coke generates a large amount of wastewater, as does the factory and living areas. This wastewater is usually discharged directly, resulting in water waste. The existing solution is to collect the domestic wastewater into a wastewater pond, pump it to a wastewater treatment plant for purification, and then use it for greening, water replenishment, and other purposes through greywater reuse facilities.

[0003] A search revealed Chinese patent CN216377526U, which discloses a wastewater treatment drug dispensing device for needle coke production. The device includes a conveying pipe with a feeding cylinder at its upper end. The feeding cylinder contains a conveying mechanism, which includes two obliquely fixed plates. An inclined plate is connected to the side of the two fixed plates that are close to each other. A scraper is connected to one end of each fixed plate. A hydraulic push rod is fixedly installed inside the conveying pipe, below the inclined plate. A second perforated plate is fixedly connected to the extended end of the hydraulic push rod, and a first perforated plate is fixedly connected to one end of the second perforated plate. This invention makes drug delivery more convenient and less prone to clogging, and also makes the device connection easier.

[0004] However, in practical use, the aforementioned existing technologies have been found to cause the entire water body in the sewage tank to flow when removing floating foam and grease from the sewage. This causes the sediment in the sewage tank to be moved, thus affecting the overall treatment effect of the sewage. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater treatment device for needle coke production.

[0006] To achieve the above objectives, this utility model provides a wastewater treatment device for needle coke production, including a wastewater tank, a connecting cylinder fixedly connected to the central shaft inside the wastewater tank, a cross-shaped partition plate fixedly connected between the wastewater tank and the connecting cylinder, uniformly distributed through holes on the side wall of the connecting cylinder, a motor fixedly installed on the top of the connecting cylinder, a rotating shaft inserted and rotatably connected inside the connecting cylinder, and the rotating shaft connected to the drive end of the motor, and uniformly distributed stirring blades fixedly connected to the outer wall of the rotating shaft.

[0007] In the above technical solution, the outer wall of the partition is further provided with a second flow hole and a first flow hole arranged vertically. An adjusting plate is slidably connected to the outer wall of the partition. A connecting frame is fixedly connected to the top of the adjusting plate. A first support plate is fixedly connected to the top of the connecting cylinder. A second support plate is fixedly connected to the top of the first support plate. A driving cylinder is fixedly installed on the top of the second support plate. A fixing block is fixedly connected to the driving end of the driving cylinder, and the fixing block is connected to the end of the connecting frame. The adjusting plate includes a mounting block fixedly connected to the bottom of the connecting frame. Two pairs of symmetrically arranged sliders are fixedly connected to the bottom of the mounting block. Multiple baffles are fixedly connected between the symmetrically arranged pairs of sliders.

[0008] In the above technical solution, a splash guard is further fixedly connected between two adjacent partitions.

[0009] In the above technical solution, the size of the first flow hole is larger than the size of the second flow hole.

[0010] In the above technical solution, the partition is further provided with several slide rails, and the slider slides in cooperation with the slide rails.

[0011] In the above technical solution, furthermore, there are four water outlet pipes at each of the four corners of the bottom of the sewage tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] Four baffles are fixed to the outer wall of the connecting cylinder, forming a cross structure and dividing the internal space of the sewage tank into four spaces. This design ensures that when skimming off foam and grease in one space, the baffles isolate the sewage in that space, while the sewage in other spaces remains undisturbed. This effectively prevents floating matter from being carried away and flowing cross-flow, thus improving sewage treatment efficiency. When flocculant is poured in, the motor drives the rotating shaft, which in turn drives the stirring blades to rotate, forming a circulation and promoting the circulation of sewage. This design allows the flocculant to mix more quickly and evenly in the sewage, thereby accelerating the flocculation reaction and improving the sewage treatment effect.

[0014] By setting up a first flow hole and a second flow hole, the stirring blades can reverse the direction of the water inside the sewage tank, enabling the water to diffuse outwards. This design optimizes the sewage flow path, allowing substances to circulate through the first and second flow holes to the next space. This reciprocating circulation significantly improves the mixing effect of flocculant and sewage, increasing sewage treatment efficiency. The connecting frame and adjusting plate are driven by a drive cylinder to move back and forth on the baffle, allowing for free adjustment of the first and second flow holes. This design allows for precise control of water flow by adjusting the degree of closure of the first and second flow holes according to actual needs. When water flow is required, the baffle does not close the first and second flow holes, allowing for a larger opening for water flow and improving the flow effect. When sedimentation is required, the baffle closes the first and second flow holes, effectively preventing mutual interference between water bodies and ensuring sedimentation.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4The wastewater treatment device for needle coke production shown includes a wastewater tank 1, a connecting cylinder 3 fixedly connected to the central axis of the wastewater tank 1, and cross-shaped partitions 2 fixedly connected between the wastewater tank 1 and the connecting cylinder 3. The side wall of the connecting cylinder 3 has evenly distributed through holes 10. A motor 6 is fixedly installed at the top of the connecting cylinder 3. A rotating shaft 8 is inserted into and rotatably connected to the inside of the connecting cylinder 3, and the rotating shaft 8 is connected to the drive end of the motor 6. Evenly distributed stirring blades 9 are fixedly connected to the outer wall of the rotating shaft 8. There are four outlet pipes at each of the four corners of the bottom of the wastewater tank 1, and four partitions 2 are fixed to the outer wall of the connecting cylinder 3, forming a cross shape. The structure divides the internal space of the sewage tank 1 into four spaces. This design ensures that when skimming off foam and grease in one space, the partition 2 isolates the sewage in that space, while the sewage in other spaces remains undisturbed. This effectively prevents floating matter from being carried away and flowing cross-currently, thus improving sewage treatment efficiency. When flocculant is poured in, the motor 6 drives the rotating shaft 8, which in turn drives the stirring blades 9 to rotate, forming a circulation and promoting sewage circulation. This design allows the flocculant to mix more quickly and evenly in the sewage, thereby accelerating the flocculation reaction and improving the sewage treatment effect.

[0022] The outer wall of the partition 2 has a second flow hole 12 and a first flow hole 11 arranged vertically. An adjusting plate 15 is slidably connected to the outer wall of the partition 2. A connecting frame 14 is fixedly connected to the top of the adjusting plate 15. A first support plate 5 is fixedly connected to the top of the connecting cylinder 3. A second support plate 7 is fixedly connected to the top of the first support plate 5. A drive cylinder 19 is fixedly installed on the top of the second support plate 7. A fixing block 13 is fixedly connected to the drive end of the drive cylinder 19, and the fixing block 13 is connected to the end of the connecting frame 14. The adjusting plate 15 includes a mounting block 16 fixedly connected to the bottom of the connecting frame 14. Two pairs of symmetrically arranged sliders 17 are fixedly connected to the bottom of the mounting block 16. Multiple baffles 18 are fixedly connected between the symmetrically arranged pairs of sliders 17. Several slide rails are provided on the partition 2, and the sliders 17 slide in cooperation with the slide rails. The size of the first flow hole 11 is larger than the size of the second flow hole 12. By setting the first flow hole 11 and the second flow hole 12, the stirring blade 9 can stir the dirt in the opposite direction. The water inside pool 1 diffuses outwards, optimizing the wastewater flow path. This allows substances to circulate through the first flow hole 11 and the second flow hole 12 to the next space. This reciprocating circulation significantly improves the mixing effect of flocculant and wastewater, increasing wastewater treatment efficiency. The connecting frame 14 and the adjusting plate 15 are driven by the drive cylinder 19 to move back and forth on the partition 2, enabling free adjustment of the first flow hole 11 and the second flow hole 12. This design allows for precise control of water flow by adjusting the degree of closure of the first flow hole 11 and the second flow hole 12 according to actual needs. When water flow is required, the baffle 18 does not close the first flow hole 11 and the second flow hole 12, allowing the water to flow with a larger opening, improving the flow effect. When sedimentation is required, the baffle 18 closes the first flow hole 11 and the second flow hole 12, effectively preventing mutual interference between water bodies and ensuring sedimentation effect.

[0023] A splash guard 4 is fixedly connected between two adjacent partitions 2. This design can prevent water splashes generated when the stirring blades 9 stir the sewage from splashing to the outside of the sewage tank 1.

[0024] Working principle:

[0025] Four baffles 2 are fixed to the outer wall of the connecting cylinder 3, forming a cross structure and dividing the internal space of the sewage tank 1 into four spaces. This design ensures that when the foam and grease in one space are scraped off, only the sewage in that space is affected due to the isolation effect of the baffles 2, while the sewage in other spaces remains undisturbed. This effectively prevents floating objects from being carried and flowing cross-flow, thus improving sewage treatment efficiency. When the flocculant is poured in, the motor 6 drives the rotating shaft 8, which in turn drives the stirring blades 9 to rotate, forming a circulation and promoting the circulation of sewage. This design allows the flocculant to mix more quickly and evenly in the sewage, thereby accelerating the flocculation reaction and improving the sewage treatment effect.

[0026] By setting the first flow hole 11 and the second flow hole 12, the stirring blade 9 can stir the water inside the sewage tank 1 in the opposite direction, realizing the diffusion of water to the outside. This design optimizes the sewage flow path, allowing substances to circulate through the first flow hole 11 and the second flow hole 12 to the next space. This reciprocating circulation method greatly improves the mixing effect of flocculant and sewage, and improves sewage treatment efficiency. The drive cylinder 19 drives the connecting frame 14 and the adjusting plate 15 to move back and forth on the partition 2, realizing the free adjustment of the first flow hole 11 and the second flow hole 12. This design allows the degree of closure of the first flow hole 11 and the second flow hole 12 to be adjusted according to actual needs, thereby achieving precise control of water flow. When water flow is required, the baffle 18 does not close the first flow hole 11 and the second flow hole 12, allowing the water to have a larger opening for flow and improving the flow effect. When sedimentation is required, the baffle 18 closes the first flow hole 11 and the second flow hole 12, effectively avoiding mutual influence between water bodies and ensuring the sedimentation effect.
