Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a circulating wastewater treatment device. Background Technology

[0002] Industrial wastewater needs to be treated before it can be discharged, requiring wastewater treatment equipment. For example, the existing patent publication number CN211847481U, entitled "A Circulating Industrial Wastewater Treatment Equipment," proposes a new type of industrial wastewater treatment equipment. This new equipment includes a first tank, a control panel on the left side of the first tank, a mixing structure on the top of the first tank, and a pH test probe at the bottom of the first tank. Through the arrangement of the first tank, control panel, mixing structure, pH test probe, partition, first water pipe, second water pipe, third water pipe, water pump, fourth water pipe, aeration structure, sampling structure, and feeder, this new equipment enables the industrial wastewater treatment equipment to detect the pH of industrial wastewater and to circulate the wastewater, ensuring that the wastewater meets standards before discharge. This solves the problem that existing industrial wastewater treatment equipment cannot detect the pH of industrial wastewater or circulate it, resulting in the continued discharge of substandard wastewater.

[0003] However, the industrial wastewater treatment equipment disclosed in the above patents is inconvenient to clean during use, which makes the filter screen prone to clogging and reduces the practicality of the equipment. Therefore, it is necessary to propose a circulating wastewater treatment equipment to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a circulating sewage treatment device to solve the problem mentioned in the background art that the existing circulating sewage treatment devices are inconvenient to clean during use, which leads to easy clogging of the filter screen and reduces the practicality of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a circulating sewage treatment device, including a treatment platform, a treatment tank and an aeration tank fixedly installed on the top of the treatment platform, a circulation component between the treatment tank and the aeration tank, and a filtration component installed inside the treatment tank.

[0006] The filtration assembly includes a filter cylinder, which is rotatably mounted on the inner wall of the top of the treatment tank via a power assembly. A connecting pipe is fixedly mounted at the bottom of the filter cylinder, and a rotary joint is rotatably mounted at the lower end of the connecting pipe. A discharge pipe is fixedly mounted at the bottom of the rotary joint, and the lower end of the discharge pipe passes through the lower surface of the treatment tank and the treatment platform in sequence. A cross is fixedly mounted inside the treatment tank, and the middle part of the cross is rotatably connected to the connecting pipe via a bearing. A fixing rod is fixedly mounted in the middle of the inner wall of the top of the treatment tank. Two symmetrically distributed scrapers are movably fitted against the inner wall of the filter cylinder, and an extension rod is fixedly connected between the scrapers and the fixing rod.

[0007] Preferably, two symmetrically distributed stirring racks are fixedly installed at the outer ring of the bottom of the connecting pipe.

[0008] Preferably, a water injection pipe is fixedly installed on the top of the treatment tank, and a chemical agent pipe is fixedly installed on the side of the treatment tank.

[0009] Preferably, the power assembly includes an annular groove fixedly formed on the inner wall of the top of the treatment tank, a limiting ring slidably disposed inside the annular groove, and both the annular groove and the limiting ring having a "T" shaped vertical cross-section. A first gear is fixedly disposed at the bottom of the limiting ring, and the first gear is fixedly disposed at the outer ring of the top of the filter cylinder. A motor is fixedly disposed at the top of the treatment tank, and the output end of the motor extends movably into the interior of the treatment tank and is fixedly connected to a second gear, which meshes with the first gear.

[0010] Preferably, the circulation assembly includes a water pump fixedly installed on the side of the aeration tank, an inlet pipe fixedly connected between the inlet end of the water pump and the treatment tank, a branch pipe one and a branch pipe two fixedly connected to the outlet end of the water pump, the other end of the branch pipe one being fixedly connected to the treatment tank, and the other end of the branch pipe two being fixedly connected to the aeration tank.

[0011] Preferably, valves are installed on the discharge pipe, branch pipe one, branch pipe two, water injection pipe and medicine pipe.

[0012] Preferably, the lower end of the filter cartridge has a cylindrical structure.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In the process of using this utility model, impurities are filtered onto the inner wall of the filter cylinder. Since the two scrapers are stationary while the filter cylinder rotates, the scrapers can clean the impurities from the inner wall of the filter cylinder. Because the lower end of the filter cylinder has a cylindrical structure, the impurities are guided into the interior of the connecting pipe and the discharge pipe. By opening the valve on the discharge pipe, the impurities can be discharged, thus preventing the filter cylinder from being blocked by impurities. This solves the problem that existing circulating sewage treatment equipment is inconvenient to clean the filter screen during use, which leads to easy clogging of the filter screen and reduces the practicality of the equipment.

[0015] 2. Industrial wastewater is discharged into the treatment tank through the water injection pipe. The filter cylinder is driven to rotate by the power component. Under the action of centrifugal force, the wastewater is filtered quickly, which improves the filtration efficiency of the device.

[0016] 3. The filtered wastewater falls to the bottom of the treatment tank. Chemicals are injected into the treatment tank through the chemical pipe to neutralize the wastewater. Since two symmetrically distributed stirring racks are fixed at the outer ring of the bottom of the connecting pipe, the rotating filter cylinder drives the stirring racks to rotate, thereby stirring the chemicals and wastewater, improving the wastewater treatment efficiency and enhancing the practicality of the device.

[0017] 4. When the wastewater passes the test, open the valve on branch pipe 2, start the water pump, and discharge the wastewater inside the treatment tank into the aeration tank for further treatment. When the wastewater fails the test, open the valve on branch pipe 1, start the water pump, and discharge the wastewater inside the treatment tank into the filter cartridge for circulation treatment, thereby improving the wastewater treatment effect of the device.

[0024] 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.

[0025] This utility model provides, for example Figures 1-5 The illustrated circulating wastewater treatment equipment includes a treatment platform 1, a treatment tank 2 and an aeration tank 3 fixedly mounted on the top of the treatment platform 1, a water injection pipe 18 fixedly mounted on the top of the treatment tank 2, a chemical pipe 19 fixedly mounted on the side of the treatment tank 2, a circulation assembly between the treatment tank 2 and the aeration tank 3, and a filtration assembly installed inside the treatment tank 2.

[0026] The filter assembly includes a filter cylinder 4, which is rotatably mounted on the inner wall of the top of the treatment tank 2 via a power assembly. A connecting pipe 10 is fixedly mounted at the bottom of the filter cylinder 4, and a rotary joint 12 is rotatably mounted at the lower end of the connecting pipe 10. A discharge pipe 13 is fixedly mounted at the bottom of the rotary joint 12. The lower end of the discharge pipe 13 passes through the lower surfaces of the treatment tank 2 and the treatment table 1 in sequence. A cross 9 is fixedly mounted inside the treatment tank 2. The middle part of the cross 9 is rotatably connected to the connecting pipe 10 via a bearing. A fixing rod 20 is fixedly mounted in the middle of the inner wall of the top of the treatment tank 2. Two symmetrically distributed scrapers 22 are movably attached to the inner wall of the filter cylinder 4. An extension rod 21 is fixedly connected between the scrapers 22 and the fixing rod 20.

[0027] The circulation component includes a water pump 14 fixedly installed on the side of the aeration tank 3. An inlet pipe 15 is fixedly connected between the inlet end of the water pump 14 and the treatment tank 2. A branch pipe 16 and a branch pipe 17 are fixedly connected to the outlet end of the water pump 14. The other end of the branch pipe 16 is fixedly connected to the treatment tank 2, and the other end of the branch pipe 17 is fixedly connected to the aeration tank 3.

[0028] Valves are installed on the discharge pipe 13, branch pipe 16, branch pipe 2 17, water injection pipe 18, and medicine pipe 19.

[0029] Specifically, industrial wastewater is discharged into the treatment tank 2 through the water injection pipe 18, and the filter cylinder 4 is driven to rotate by the power component. Under the action of centrifugal force, the wastewater is filtered quickly, thereby improving the filtration efficiency of the device.

[0030] Impurities are filtered onto the inner wall of the filter cylinder 4. Since the two scrapers 22 are stationary while the filter cylinder 4 rotates, the scrapers 22 can clean the impurities from the inner wall of the filter cylinder 4. Because the lower end of the filter cylinder 4 has a cylindrical structure, the impurities are guided to fall into the interior of the connecting pipe 10 and the discharge pipe 13. By opening the valve on the discharge pipe 13, the impurities can be discharged, preventing the filter cylinder 4 from being blocked by impurities. This solves the problem that existing circulating sewage treatment equipment is inconvenient to clean the filter screen during use, which leads to easy clogging of the filter screen and reduces the practicality of the equipment.

[0031] The filtered wastewater falls to the bottom of the treatment tank 2. Chemicals are injected into the treatment tank 2 through the chemical pipe 19 to neutralize the wastewater. Since two symmetrically distributed stirring racks 11 are fixedly installed at the outer ring of the bottom of the connecting pipe 10, the rotating filter cylinder 4 drives the stirring racks 11 to rotate, thereby stirring the chemicals and wastewater, improving the wastewater treatment efficiency and enhancing the practicality of the device.

[0032] When the wastewater passes the test, open the valve on branch pipe 17, start the water pump 14, and discharge the wastewater inside treatment tank 2 into aeration tank 3 for further treatment. When the wastewater fails the test, open the valve on branch pipe 16, start the water pump 14, and discharge the wastewater inside treatment tank 2 into filter cylinder 4 for circulation treatment, thereby improving the wastewater treatment effect of the device.

[0033] Furthermore, the power assembly includes an annular groove fixedly formed on the inner wall of the top of the treatment tank 2. A limiting ring 6 is slidably arranged inside the annular groove. The vertical cross-sections of both the annular groove and the limiting ring 6 are T-shaped. A gear 5 is fixedly arranged at the bottom of the limiting ring 6. The gear 5 is fixedly arranged on the outer ring of the top of the filter cylinder 4. A motor 7 is fixedly arranged at the top of the treatment tank 2. The output end of the motor 7 extends movably into the interior of the treatment tank 2 and is fixedly connected to a gear 8. The gear 8 and the gear 5 mesh with each other. When the motor 7 is started, the gear 8 is driven to rotate, which in turn drives the gear 5 and the filter cylinder 4 to rotate.

[0034] Working principle: Industrial wastewater is discharged into the treatment tank 2 through the water injection pipe 18. The motor 7 is started, driving gear 2 8 to rotate, which in turn drives gear 1 5 and the filter cylinder 4 to rotate. Under centrifugal force, the wastewater is quickly filtered, and impurities are trapped on the inner wall of the filter cylinder 4. Since the two scrapers 22 are stationary while the filter cylinder 4 rotates, the scrapers 22 can clean the impurities from the inner wall of the filter cylinder 4. Because the lower end of the filter cylinder 4 has a cylindrical structure, the impurities are guided into the connecting pipe 10 and the discharge pipe 13. Opening the valve on the discharge pipe 13 allows the impurities to be discharged, preventing the filter cylinder 4 from being clogged. The filtered wastewater falls to the bottom of the treatment tank 2. Chemicals are injected into the treatment tank 2 through the chemical pipe 19 to neutralize the sewage. Since two symmetrically distributed stirring racks 11 are fixedly installed at the bottom outer ring of the connecting pipe 10, the rotating filter cylinder 4 drives the stirring racks 11 to rotate, thereby stirring the chemicals and sewage and improving the sewage treatment efficiency. When the sewage passes the test, the valve on the branch pipe 2 17 is opened and the water pump 14 is started to discharge the sewage in the treatment tank 2 into the aeration tank 3 for further treatment. When the sewage fails the test, the valve on the branch pipe 16 is opened and the water pump 14 is started to discharge the sewage in the treatment tank 2 into the filter cylinder 4 for circulation treatment to ensure the sewage treatment effect.

[0035] The wiring diagrams of the motor 7 and water pump 14 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 7 and water pump 14 will not be explained in detail.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
