Description

Technical Field

[0001] The present invention relates to the field of industrial wastewater purification, and in particular to an industrial wastewater purification device for environmental protection engineering. Background Art

[0002] Industrial wastewater purification refers to the removal of pollutants from wastewater generated during industrial production through various technical means to achieve water resource reuse or meet environmental emission standards. The composition and types of pollutants in industrial wastewater vary from industry to industry, including chemicals, organic matter, heavy metals, suspended solids, grease, pH, etc. The goal of industrial wastewater purification is to remove or reduce the concentration of these pollutants, protect the water environment, and prevent pollutants from causing harm to the ecosystem or human health.

[0003] For example, the Chinese patent publication number is CN109081511B, and the technical solution disclosed in the patent document is as follows: an industrial sewage purification device for environmental protection engineering, including a purifier body, a support frame is provided at the lower end of the purifier body, a bearing block is provided on the outer surface of one side of the inner part of the purifier body, a filter device is provided at the upper end of the bearing block inside the purifier body, a bearing device is provided through the lower end of the filter device on the outer surface of the bottom end of the purifier body, a water inlet is provided through the upper part of the filter device on the outer surface of one side of the purifier body, and a conveying pipe is provided through the other side of the purifier body. The industrial sewage purification device for environmental protection engineering can improve the purification performance through the filtering device, facilitate the replacement of the filter screen through the bearing device, facilitate the cleaning of the sedimentation tank through the cleaning device, and facilitate the replacement of the activated sludge through the pulling device.

[0004] The existing technology has the following problems: Since the lower filter cannot be fixed on the bearing block, friction or impact may occur between the filter and the inner wall of the purifier body. During the filtration process, when the sewage flow rate is high, the grid may be subjected to uneven water flow pressure, resulting in damage or deformation, affecting the subsequent filtration effect, and even causing long-term damage to the equipment; if the lower filter is unstable during the sewage purification process, the water flow impact it bears will be uneven, which may cause the filter to wear faster and significantly shorten its life. Since there is no bearing block or other supporting structure, the stability of the filter cannot be guaranteed. Long-term use will reduce the service life of the equipment, and the filter needs to be replaced frequently, increasing maintenance costs. Summary of the invention

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0025] like Figure 1-5 As shown, the present invention provides an industrial sewage purification device for environmental protection engineering, including a purifier body 1, which is the core structure of the entire device, carries all internal components, and ensures the smooth progress of the sewage treatment process. Its main function is to provide support, connection and closed space for filtering and purifying sewage. The purifier body 1 includes a body 11, and a cover plate 12 is provided at the upper end of the body 11 to facilitate the cleaning and maintenance of the internal components of the equipment, prevent sewage overflow and environmental pollution, and the bottom of the body 11 is fixedly connected with a support leg 13 to provide equipment stability, support the weight of the device, and prevent the equipment from tilting or sliding. A connecting cylinder 2 is provided on the side of the body 11, and the purifier and the sedimentation tank 3 are connected through a pipeline to form a flow channel for sewage. The design of the connecting cylinder 2 ensures that the sewage can flow smoothly into the sedimentation tank 3. The other end of the connecting cylinder 2 is fixedly connected to the sedimentation tank 3. The sedimentation tank 3 is used to store sewage and provide sedimentation to remove particulate matter in the sewage. The sedimentation tank 3 uses the principle of physical sedimentation to allow solid impurities to settle to the bottom, and the purified water can be discharged from the top. A support column 4 is fixedly connected to the bottom of the sedimentation tank 3. A filter assembly 5 is arranged inside the main body 1 of the purifier. The filter assembly 5 is used to filter the sewage multiple times to remove solid particles and impurities therein. The filter assembly 5 includes an upper filter 51 and a lower filter 53, and the two filter nets perform two-stage filtration respectively. The upper filter 51 performs preliminary filtration to remove larger impurities; the lower filter 53 performs secondary filtration to remove fine impurities. The two work together to ensure the sewage purification effect. A connecting sleeve 52 is fixedly connected between the upper filter 51 and the lower filter 53. A sealing ring 54 is arranged on the outside of the upper filter 51 and the lower filter 53. An auxiliary replacement assembly 6 is arranged inside the main body 1 of the purifier. The main function of the auxiliary replacement assembly 6 is to provide a convenient and quick way to replace the filter. When the filtering performance of the filter is reduced or needs to be cleaned, the filter can be quickly lifted and removed by this assembly; The auxiliary replacement assembly 6 includes a cylinder 61, which is fixedly connected to the bottom of the body 11, and the output end of the cylinder 61 is fixedly connected to a connecting plate A62, and the upper end of the connecting plate A62 is fixedly connected to a lifting rod 63, and the outer wall of the lifting rod 63 is fixedly connected to a lifting block 64. The inner wall of the body 11 is fixedly connected to a fixed cylinder 65, and the interior of the fixed cylinder 65 is slidably connected to a moving rod 66, and the inner wall of the fixed cylinder 65 is fixedly connected to a spring 67, and the other end of the spring 67 is fixedly connected to the moving rod 66, and the end of the moving rod 66 away from the spring 67 is fixedly connected to a moving block 68, and the inner wall of the body 11 is fixedly connected to a fixed plate 69, and the fixed plate 69 is fixedly connected to the inner wall of the body 11. The outer walls on both sides are rotatably connected with a rotating plate 610 through a pin shaft, and the outer walls at both ends of the rotating plate 610 are provided with a slide groove 611. The inner wall of the body 11 is fixedly connected with a bearing block 612, and a slot 613 is provided at the upper end of the bearing block 612. A through hole is provided on the side of the bearing block 612, and a positioning rod 614 is slidably connected inside the through hole. The positioning rod 614 and both sides of the moving rod 66 are fixedly connected with a sliding shaft 615, and the sliding shaft 615 is slidably connected to the bottom of the lower filter 53. A plug-in block 616 is fixedly connected, and a positioning hole 617 is provided on the side of the plug-in block 616. A horizontal plate 618 is fixedly connected to the bottom of the lower filter 53. The aperture of the positioning hole 617 is consistent with that of the through hole and matches the diameter of the positioning rod 614. The size of the plug-in block 616 is consistent with that of the slot 613. The plug-in block 616 is inserted into the slot 613 to fix the position of the filter to prevent the filter from being displaced during use. When replacing the filter, the cooperation between the insert block 616 and the slot 613 can ensure the stability of the filter.

[0026] When in use, the user can connect the sewage pipe to the water inlet on the purifier body 1, and then open the water valve to allow the sewage to enter the filter assembly 5 inside the purifier body 1 through the water inlet, so that the sewage is filtered once by the filtering performance of the upper filter 51, and the sewage after the first filtration will fall downward onto the lower filter 53 through the connecting sleeve 52, so that the sewage after the first filtration will be filtered twice by the lower filter 53. Because a sealing ring 54 is provided between the upper filter 51 and the lower filter 53 and the purifier body 1, the sewage will not flow downward from the gap between the filter assembly 5 and the purifier body 1 when filtering the sewage. Long-term use will reduce the filtering performance of the filter. The filter needs to be replaced. At this time, the cylinder 61 is started to drive the lifting rod 63 to move upward through the connecting plate A62, and then the lifting block 64 fixedly mounted on the lifting rod 63 will also move upward inside the machine body 11. When the lifting block 64 contacts the moving block 68, since the contact surfaces of the lifting block 64 and the moving block 68 are both inclined surfaces, when the lifting block 64 continues to move upward, the moving block 68 will move to both sides, and then the moving rod 66 fixedly connected to the moving block 68 will slide toward the inside of the fixed cylinder 65. When the moving rod 66 moves, the sliding shafts 615 on both sides of it will also move. Then the sliding shafts 615 located on the side of the moving rod 66 will also move at the bottom of the rotating plate 610. The sliding groove 611 of the rotating plate 610 will slide inside, and then the rotating plate 610 will rotate around the central pin shaft. Then the rotating plate 610 will drive the sliding shafts 615 located on both sides of the positioning rod 614 to move toward the middle of the body 11 through the sliding groove 611 at the upper end, and then the positioning rod 614 will also move. Then the positioning rod 614 will leave the inside of the positioning hole 617 on the side of the plug block 616. At this time, the lifting rod 63 is in contact with the cross plate 618, and then the lifting rod 63 will drive the filter to rise through the cross plate 618, and drive the plug block 616 to leave the slot 613. At this time, open the cover plate 12, and the filter can be taken out, and then it can be replaced and cleaned. When a new filter needs to be placed, first The lifting rod 63 is reset, and then the above operation is performed, so that the positioning rod 614 leaves the interior of the slot 613. At this time, the filter is placed in, so that the plug block 616 at the bottom is inserted into the interior of the slot 613. The lifting rod 63 is reset. At this time, under the action of the spring 67, the moving rod 66 will be pushed to move toward the middle of the body 11. Then, under the same principle, the positioning rod 614 will move sideways, thereby entering the interior of the positioning hole 617 on the side of the plug block 616, thereby achieving the lifting of the filter while releasing the fixation of the filter. Compared with simply placing the filter on the upper end of the support block 612, the impact between the filter and the inner wall of the body 11 is reduced, and the possibility of the filter floating up and down is avoided. Example

[0027] like Figure 1-6As shown, a lifting assembly 7 is provided on the side of the sedimentation tank 3, and the lifting assembly 7 is used to lift the storage bucket 79 in the sedimentation tank 3 so as to replace the activated sludge. The lifting assembly 7 includes a connecting rod A71, which is fixedly sleeved on the outer wall of the lifting rod 63, and the upper end of the connecting rod A71 is fixedly connected to a tooth plate 72. A mounting plate 73 is fixedly connected to the top of the sedimentation tank 3, and a rotating shaft A74 is rotatably connected to the outer wall of the mounting plate 73. One end of the rotating shaft A74 passes through the mounting plate 73 and is fixedly connected to a transmission gear 75. The other end of the rotating shaft A74 is fixedly connected to a take-up wheel 76, and a connecting rope 77 is wound around the outer wall of the take-up wheel 76. The bottom end of the connecting rope 77 is fixedly connected to a connecting plate B78, and the two ends of the connecting plate B78 are fixedly connected to the storage bucket 79. The outer wall of the mounting plate 73 is fixedly connected to a mounting shaft 710, and the other end of the mounting shaft 710 is fixedly connected to a guide wheel 711, and the connecting rope 77 is slidably connected to the outer side of the guide wheel 711.

[0028] When in use, the operation of the lifting assembly 7 starts from starting the cylinder 61. The cylinder 61 drives the lifting rod 63 to rise through the output end. The drive of the cylinder 61 enables the lifting rod 63 to move upward in the vertical direction. When the lifting rod 63 rises, the connecting rod A71 transmits its movement to the toothed plate 72. The toothed plate 72 is meshed with the transmission gear 75, and the lifting and lowering of the toothed plate 72 causes the rotation of the transmission gear 75. The rotation of the transmission gear 75 directly drives the rotation of the rotating shaft A74, and the rotation of the rotating shaft A74 drives the rotation of the take-up wheel 76. The take-up wheel 76 reels the connecting rope 77 by rotating, and the lower end of the connecting rope 77 is fixed to the upper end of the holding bucket 79. As the connecting rope 77 is reeled, the holding bucket 79 is gradually pulled up. The function of the guide wheel 711 is to ensure that the connecting rope 77 remains stable during the lifting process and prevent it from deviating from the predetermined trajectory, thereby ensuring that the lifting process of the holding barrel 79 is smooth. When the holding barrel 79 rises to the predetermined position, the activated sludge in the sedimentation tank 3 is successfully extracted and is ready for replacement. At this time, the sludge in the holding barrel 79 can be cleaned or subjected to other treatment operations. The lifting action of the holding barrel 79 enables the activated sludge in the sedimentation tank 3 to be replaced regularly, avoiding excessive accumulation of sludge and resulting in a decrease in treatment effect. The entire process realizes the automation and mechanization of sludge replacement, reduces the complexity and labor intensity of manual operations, and effectively reduces possible pollution risks. Example

[0029] like Figure 1-7As shown, a supporting assembly 8 is provided inside the sedimentation tank 3, and the supporting assembly 8 is used to support and stabilize the movement of the containing bucket 79, to ensure that the containing bucket 79 remains stable during the lifting process, and to avoid damage or unstable lifting and lowering. The supporting assembly 8 includes a transmission wheel A81, which is fixedly sleeved on the outer wall of the rotating shaft A74, a transmission belt 82 is wound around the outer wall of the transmission wheel A81, and a transmission wheel B83 is connected to the inner side of the other end of the transmission belt 82 for transmission. The outer wall of the mounting plate 73 is rotatably connected to the rotating shaft B84, and the transmission wheel B83 is fixedly sleeved on the outer wall of the rotating shaft B84. A mounting block 85 is fixedly connected to the upper end of the sedimentation tank 3, and a threaded rod 86 is rotatably connected to the outer wall of the mounting block 85, and a bevel gear B88 is fixedly connected to the other end of the threaded rod 86, and a bevel gear A87 is fixedly connected to the end of the rotating shaft B84 away from the mounting plate 73, and a connecting rod B89 is threadedly connected to the outer wall of the threaded rod 86, and a supporting plate 810 is fixedly connected to the bottom of the connecting rod B89. A moving groove 811 is provided on the top of the sedimentation tank 3 , and a connecting rod B89 is slidably connected inside the moving groove 811 .

[0030] During use, when the rotating shaft A74 rotates, it will drive the transmission wheel A81 to rotate, and then the transmission wheel B83 will be driven to rotate under the transmission action of the transmission belt 82, then the rotating shaft B84 in the middle of the transmission wheel B83 will rotate accordingly, and then it will drive the bevel gear A87 to rotate, and then the bevel gear B88 meshing with it will rotate at any time, and then it can drive the threaded rod 86 to rotate, then the connecting rod B89 threadedly connected to its outer wall will slide inside the moving groove 811, and then the support plate 810 at the bottom of the connecting rod B89 will also move accordingly, when the holding barrel 79 moves upward, the support plate 810 moves in the direction of the holding barrel 79, when the holding barrel 79 moves to the moving height, the support plate 810 is just located at its bottom, thereby ensuring the stability when replacing the activated sludge inside the holding barrel 79.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
