Description

Technical Field

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

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly becoming a part of ordinary people's daily lives.

[0003] In wastewater treatment, it is often necessary to first filter the wastewater through a filter screen. However, after prolonged use, a large amount of material tends to accumulate on the filter screen, making it inconvenient to clean and prone to clogging. If the filter screen is not cleaned for a long time, it will affect its service life. Moreover, cleaning a traditional filter screen requires shutting off the wastewater supply before cleaning the filter screen, which is inconvenient. Utility Model Content

[0004] The technical problem this invention aims to solve is to address the aforementioned technical deficiencies by providing a wastewater treatment device. This structure facilitates the cleaning of blockages within the filter screen, extends its service life, and does not affect the normal inlet filtration of the wastewater pipe during cleaning, thus facilitating wastewater treatment.

[0005] The technical solution adopted by this utility model is as follows: A sewage treatment device is provided, including a filter tank with a sewage pipe installed on it. The device is characterized by: a circular plate fixedly connected to the outside of the sewage pipe, and the circular plate being fixedly connected to the filter tank; an annular filter screen being installed inside the filter tank; one end of the filter screen being rotatably connected to the circular plate, and the other end being fixedly connected to a driven toothed plate; the driven toothed plate being rotatably connected to the filter tank via a bracket; a drive motor being installed on the bracket, and a drive gear meshing with the driven toothed plate being fixedly connected to the output end of the drive motor; multiple baffles being evenly distributed on the inner side of the filter screen; and a sewage discharge device corresponding to the baffles being installed on the circular plate.

[0006] To further optimize this technical solution, a sewage discharge device for a sewage treatment equipment includes a discharge shell; above the sewage pipe, a discharge port is opened on a circular plate; the discharge shell is installed on the discharge port, and one end of the discharge shell extends into the filter screen; the discharge shell is inclined.

[0007] To further optimize this technical solution, a sludge receiving container corresponding to the sludge discharge shell is provided on one side of the filter tank of a sewage treatment device.

[0008] To further optimize this technical solution, a baffle for a sewage treatment device includes a vertical plate and an inclined plate.

[0009] To further optimize this technical solution, one end of a baffle in a sewage treatment device is fixedly connected to a driven toothed plate; the other end of the baffle is slidably fitted to a circular plate.

[0010] To further optimize this technical solution, a drainage pipe is connected to the lower end of the filter tank of a sewage treatment device.

[0011] To further optimize this technical solution, a sewage treatment device has a sewage discharge pipe connected to the upper part of its filter tank.

[0012] To further optimize this technical solution, the outlet of the sewage pipe of a sewage treatment device is located at the lower part of the filter screen.

[0013] Compared with traditional sewage treatment equipment, the advantages of this utility model are as follows:

[0014] 1. The combination of sewage pipe, circular plate, filter screen, and driven toothed plate filters out large particles in sewage. The sewage discharge pipe discharges the floating objects in the upper layer of the filter tank for further filtration, making it convenient for sewage filtration treatment.

[0015] 2. The combination of filter screen, drive motor, drive gear, driven gear plate, baffle, drain shell, drain port, and waste collection container facilitates the cleaning of blockages in the filter screen, extends its service life, and does not affect the normal water inlet filtration of the sewage pipe during cleaning.

[0016] 3. The inclined design of the baffle makes it easier for objects to fall and makes cleaning the filter screen more convenient. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-4As shown, a wastewater treatment device includes a filter tank 1 with a wastewater pipe 2 installed on it. The device is characterized by: a circular plate 3 fixedly connected to the outside of the wastewater pipe 2, and the circular plate 3 being fixedly connected to the filter tank 1; an annular filter screen 4 installed inside the filter tank 1; one end of the filter screen 4 being rotatably connected to the circular plate 3, and the other end of the filter screen 4 being fixedly connected to a driven toothed plate 5; the driven toothed plate 5 being rotatably connected to the filter tank 1 via a bracket 14; a drive motor 6 mounted on the bracket 14, and a drive gear 7 meshing with the driven toothed plate 5 being fixedly connected to the output end of the drive motor 6; multiple baffles 8 evenly distributed on the inner side of the filter screen 4; and a circular plate 3 being provided with... A sewage discharge device corresponding to the baffle 8 is provided; the sewage discharge device includes a sewage discharge shell 9; above the sewage pipe 2, a sewage discharge port 10 is opened on the circular plate 3; the sewage discharge shell 9 is installed on the sewage discharge port 10, and one end of the sewage discharge shell 9 extends into the filter screen 4; the sewage discharge shell 9 is inclined; a sewage receiving container 11 corresponding to the sewage discharge shell 9 is provided on one side of the filter pool 1; the baffle 8 includes a vertical plate 81 and an inclined plate 82; one end of the baffle 8 is fixedly connected to the driven toothed plate 5; the other end of the baffle 8 is slidably attached to the circular plate 3; a drain pipe 12 is connected to the lower end of the filter pool 1; a sewage discharge pipe 13 is connected to the upper part of the filter pool 1; the outlet of the sewage pipe 2 is located at the lower part of the filter screen 4.

[0024] In use, sewage flows through sewage pipe 2 into the chamber composed of circular plate 3, filter screen 4 and driven toothed plate 5. Filter screen 4 filters the sewage, removing large particles. The filtered sewage then enters the filter tank 1, while some particles with a density less than water float in the filter tank 1. The sewage pipe 13 can discharge the floating particles in the upper layer of the filter tank 1 for further filtration, making it convenient for sewage filtration treatment.

[0025] Over time, a large amount of filtered material will adhere to the filter screen 4. If it is not cleaned, it will easily become clogged. At this time, the drive motor 6 is turned on. The drive motor 6 drives the drive gear 7 to rotate. The drive gear 7 drives the driven gear plate 5 that meshes with it to rotate. The driven gear plate 5 drives the filter screen 4 that is fixedly connected to it to rotate. The filter screen 4 drives the baffle 8 on it to rotate. The angle between the baffle 8 and the filter screen 4 will pick up some of the material inside the filter screen 4. When the baffle 8 rotates to the top of the drain shell 9, the material inside the baffle 8 will fall into the drain shell 9 due to gravity. The drain shell 9 is tilted. The material will move after falling onto the drain shell 9 and will reach the waste container 11 through the drain port 10. This makes it easier to clean the clogged material inside the filter screen 4, resulting in a longer service life. Moreover, cleaning does not affect the normal water intake of the sewage pipe 2. Many traditional filters require stopping the water intake before cleaning the filter screen 4.

[0026] The baffle 8, which consists of a vertical plate 81 and an inclined plate 82, is designed such that when the baffle 8 is above the drain shell 9, the inclined plate 82 makes it easier for objects to fall and makes cleaning the filter screen 4 more convenient.

[0027] The sliding fit between the filter screen 4 and the circular plate 3, along with the rotational connection between the driven toothed plate 5 and the bracket 14, makes the rotation of the filter screen 4 and the driven toothed plate 5 more stable.

[0028] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0029] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
