Description

Technical Field

[0001] This utility model relates to the technical field of coking wastewater treatment equipment, specifically a treatment device for zero discharge of coking wastewater. Background Technology

[0002] Coking wastewater is a typical type of toxic and recalcitrant organic wastewater. It mainly originates from the primary cooling of coke oven gas and the production water used in the coking process, as well as steam condensate wastewater. It refers to the wastewater generated during coal coking, gas purification, chemical product recovery, and chemical product refining.

[0003] Existing coking wastewater treatment equipment often lacks oil residue handling mechanisms. Due to the high viscosity and strong adhesion of oil in coking wastewater, untreated oil easily adheres to the reaction chambers, pipe walls, and filter surfaces, clogging filtration channels, affecting fluid flow efficiency, and reducing the contact area between the equipment and the wastewater. This significantly reduces the effectiveness of subsequent purification treatment and overall treatment efficiency. Therefore, we propose a treatment device for zero-discharge coking wastewater. Utility Model Content

[0004] The purpose of this utility model is to provide a treatment device for zero discharge of coking wastewater, in order to solve the problem mentioned in the background art that some existing coking wastewater treatment devices lack oil stain treatment structure. Due to the high viscosity and strong adhesion of oil stains in coking wastewater, untreated oil stains are prone to adhere in large quantities to the reaction chamber, inner wall of pipes and surface of filter components of the equipment. This not only blocks the filter channels and affects the fluid flow efficiency, but also reduces the contact reaction area between the equipment and the wastewater, resulting in a significant reduction in the subsequent purification effect and a substantial decrease in the overall treatment efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a treatment device for zero discharge of coking wastewater, comprising: an operating table, a treatment tank fixedly connected to the upper surface of the operating table, an outlet pipe provided on the side surface of the treatment tank, an adjusting component fixedly connected to the upper surface of the operating table, a filter component provided on the outer surface of the adjusting component, a cleaning component provided on the outer surface of the adjusting component, the filter component being controlled by the adjusting component to rotate at an adjustable speed, and the cleaning component scraping off oil stains on the filter component.

[0006] The adjustment component includes a support column, which is fixedly connected to the upper surface of the operating table. A support plate is fixedly connected to the top of the support column. A speed controller is installed on the outer surface of the support plate, and a drive motor is fixedly connected to the upper surface of the support plate.

[0007] The output end of the drive motor is fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to a rotating head. A connecting slot is opened through the outer surface of the rotating head.

[0008] The filter assembly includes an oil filter frame, which is movably connected inside the treatment tank. A connecting rod is fixedly connected to the center of the oil filter frame, and a connecting buckle is fixedly connected to the upper surface of the connecting rod. The top of the connecting buckle is movably connected to the inside of the connecting buckle groove.

[0009] The cleaning component includes a scraper, the outer surface of which is movably connected to the side wall and bottom wall of the oil filter frame. A connecting bolt is movably connected to the top of the scraper, and a fixing clamp is movably connected to the outer surface of the connecting bolt. The fixing clamp is fixedly connected to the outermost end of the support plate.

[0010] The connecting rod is movably connected to the drive motor via a connecting buckle plate and a rotating head.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. In use, this utility model connects a support plate to a support column in the adjustable assembly. The support plate carries a speed controller and a drive motor. The drive motor, through a connecting plate, a rotating head, and a connecting groove, links the connecting plate, connecting rod, and oil filter frame of the filter assembly. This allows for flexible adjustment of the oil filter frame speed according to the characteristics of the oil in the coking wastewater. It can enhance the centrifugal filtration effect when the oil concentration is high and the viscosity is high, and reduce energy consumption when the concentration is low. This improves the adaptability and economy of oil-water separation and ensures stable and reliable filtration effect.

[0013] 2. In use, the scraper in the cleaning component is connected to the fixing clamp via a connecting bolt. The fixing clamp is fixed to the support plate of the adjusting component, so that the scraper fits tightly against the inner wall and bottom of the filter frame of the filter component. This achieves synchronous oil removal during the rotation of the filter frame, preventing oil accumulation and clogging of the mesh, and ensuring stable filtration efficiency. At the same time, the scraped oil is concentrated at the bottom of the filter frame. Combined with the movable connection design of the connecting buckle plate and the connecting buckle groove, it is easy to quickly disassemble and clean, reducing the difficulty of equipment maintenance and extending the continuous working time.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a treatment device for zero discharge of coking wastewater, comprising: an operating table 1, a treatment tank 2 fixedly connected to the upper surface of the operating table 1, a water outlet pipe 3 opened on the side surface of the treatment tank 2, an adjusting component 4 fixedly connected to the upper surface of the operating table 1, a filter component 5 provided on the outer surface of the adjusting component 4, a cleaning component 6 provided on the outer surface of the adjusting component 4, the filter component 5 being controlled by the adjusting component 4 to rotate at an adjustable speed, and the cleaning component 6 scraping off the oil stains on the filter component 5.

[0021] In use, the support plate 42 is connected to the support column 41 in the adjustment component 4. The support plate 42 carries the speed controller 43 and the drive motor 44. The drive motor 44 is linked to the connecting plate 53, connecting rod 52 and oil filter frame 51 of the filter component 5 through the connecting plate 45, rotating head 46 and connecting groove 47. This allows for flexible adjustment of the speed of the oil filter frame 51 according to the characteristics of the oil in the coking wastewater. It can enhance the centrifugal filtration effect when the oil concentration is high and the viscosity is high, and reduce energy consumption when the concentration is low. This improves the adaptability and economy of oil-water separation and ensures stable and reliable filtration effect.

[0022] The adjustment assembly 4 includes a support column 41, which is fixedly connected to the upper surface of the operating table 1. A support plate 42 is fixedly connected to the top of the support column 41. A speed controller 43 is provided on the outer surface of the support plate 42, and a drive motor 44 is fixedly connected to the upper surface of the support plate 42. A connecting plate 45 is fixedly connected to the output end of the drive motor 44, and a rotating head 46 is fixedly connected to the bottom of the connecting plate 45. A connecting slot 47 is provided through the outer surface of the rotating head 46.

[0023] The filter assembly 5 includes an oil filter frame 51, which is movably connected inside the treatment tank 2. A connecting rod 52 is fixedly connected to the center of the oil filter frame 51, and a connecting buckle plate 53 is fixedly connected to the upper surface of the connecting rod 52. The top of the connecting buckle plate 53 is movably connected to the inner side of the connecting buckle groove 47. The cleaning assembly 6 includes a scraper 61, the outer surface of which is movably connected to the side wall and bottom wall of the oil filter frame 51. A connecting bolt 62 is movably connected to the top of the scraper 61, and a fixing clamp 63 is movably connected to the outer surface of the connecting bolt 62. The fixing clamp 63 is fixedly connected to the outermost end of the support plate 42.

[0024] Before starting the equipment, the coking wastewater to be treated should be introduced into the treatment tank 2, with the wastewater level ideally submerging the oil filter frame 51 of the filter assembly 5. The adjusting assembly 4, as the core drive unit, has its bottom support column 41 fixedly connected to the upper surface of the operating table 1, providing stable support for the entire assembly. The support plate 42 fixed to the top of the support column 41 not only supports the speed controller 43 and the drive motor 44, but also provides an installation reference for the fixing clamp 63 of the cleaning assembly 6. Operators can preset the speed of the drive motor 44 according to the concentration and viscosity of the oil in the coking wastewater via the speed controller 43 on the outer surface of the support plate 42. If the oil concentration is high and the viscosity is large, a higher speed can be set to enhance the centrifugal filtration effect; if the oil concentration is low, the speed can be reduced to save energy, achieving flexible treatment that can be adjusted as needed.

[0025] After the drive motor 44 is started, the connecting plate 45 fixedly connected to its output end rotates accordingly, thereby driving the rotating head 46 at the bottom of the connecting plate 45 to rotate synchronously. Since the connecting buckle plate 53 fixed on the upper surface of the connecting rod 52 of the filter assembly 5 is movably connected to the inner side of the connecting buckle groove 47 that penetrates through the outer surface of the rotating head 46, and the connecting rod 52 and the drive motor 44 are movably connected through the connecting buckle plate 53 and the rotating head 46, the rotational force of the rotating head 46 can be directly transmitted to the connecting rod 52, driving the oil filter frame 51 to rotate at a preset speed inside the treatment tank 2. The oil filter frame 51 adopts a porous mesh structure, and its pore size is adapted to the interception requirements of oil particles in coking wastewater. During the rotation, the wastewater flows into the inner side of the treatment tank 2 through the mesh of the oil filter frame 51 under the action of centrifugal force, while the less dense oil adheres to the inner wall and bottom of the oil filter frame 51 due to centrifugal force, achieving preliminary separation of oil and water.

[0026] While the filter assembly 5 rotates and filters, the cleaning assembly 6 simultaneously scrapes away oil, preventing oil from accumulating and clogging the mesh of the oil filter frame 51. The scraper 61 of the cleaning assembly 6 is made of elastic and wear-resistant material, and its outer surface is tightly attached to the side and bottom walls of the oil filter frame 51. The top of the scraper 61 is movably connected to the fixed clamp 63 via a connecting bolt 62, and the fixed clamp 63 is fixedly connected to the outermost end of the support plate 42, so that the scraper 61 remains stationary when the oil filter frame 51 rotates. When the oil filter frame 51 rotates, the oil adhering to its surface slides relative to the scraper 61, and the edge of the scraper 61 scrapes the oil off the surface of the oil filter frame 51. The scraped oil settles to the bottom of the oil filter frame 51 under gravity, making it easy to clean and recycle later.

[0027] As the filtration process continues, the amount of purified wastewater inside treatment tank 2 gradually increases. When the water level reaches the preset height, the outlet pipe 3 on the side surface of treatment tank 2 can be opened to discharge the purified wastewater to the subsequent deep treatment unit, achieving zero-discharge pretreatment of coking wastewater. If the filter frame 51 needs to be replaced or cleaned, simply turn off the drive motor 44, push and pull the filter frame 51 inward to allow the connecting buckle plate 53 to disengage from the connecting buckle groove 47 for quick disassembly. The operation is convenient and does not affect the operation of other components of the equipment.
