Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an oxidation ditch wastewater treatment device with sludge collection. Background Technology

[0002] Oxidation ditches are a variation of the activated sludge process. Their aeration tanks are closed channels, so their hydraulic flow patterns differ from those of the traditional activated sludge process. They are interconnected circulating aeration ditches where wastewater seeps in and is purified. Existing oxidation ditches will produce a large amount of sludge during the wastewater treatment process. If this sludge is not treated in time, it will affect the wastewater treatment capacity of the oxidation ditch.

[0003] In current technologies for treating wastewater in oxidation ditches, the resulting filter sludge cannot be quickly removed from the wastewater treatment equipment. This causes the equipment to become heavier due to the sludge buildup over time, thus increasing energy consumption. Therefore, this invention proposes an oxidation ditch wastewater treatment device with sludge collection to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an oxidation ditch wastewater treatment device with sludge collection. By setting a filtration mechanism consisting of a mounting frame, a drive roller, a driven roller, and a filter belt on the top of the movable frame on the oxidation ditch, sludge can be quickly filtered. The sludge intercepted on the filter belt can be quickly discharged at the sludge scraping and discharge mechanism. The sludge is discharged from the device simultaneously with the wastewater treatment, so that the operation of the device is not affected by the weight of the sludge, which can effectively reduce energy consumption and improve wastewater treatment efficiency.

The input ends of the multiple sets of sludge suction pumps are all connected to the upper end of the sludge suction pipe. The output ends of the multiple sets of sludge suction pumps are all provided with sludge discharge pipes.

[0010] A further improvement is that: a protective frame is provided above the filter belt, the sewage pipe is located above the protective frame, and the sewage pipe is provided with multiple sewage outlets leading to the interior of the protective frame.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1-3 As shown in the figure, this embodiment proposes an oxidation ditch wastewater treatment device with sludge collection, including a movable frame 2 installed on an oxidation ditch 1. A mounting frame 3 is provided on one side of the top of the movable frame 2. The mounting frame 3 is equipped with an active roller and a driven roller. A filter belt 4 is connected between the active roller and the driven roller. A sludge suction mechanism 5 is provided on the top of the movable frame 2 on one side of the mounting frame 3. The input end of the sludge suction mechanism 5 is connected to the interior of the oxidation ditch 1. The output end of the sludge suction mechanism 5 is located above the filter belt 4. A water collection tank 6 is provided inside the filter belt 4. The water collection tank 6 is connected to the mounting frame 3 by bolts. A drain pipe 7 is provided on one side of the water collection tank 6. There are multiple drain pipes 7, and all of the multiple drain pipes 7 lead to the interior of the oxidation ditch 1. A sludge scraping and sludge discharge mechanism 8 is provided below the output end of the filter belt 4. The sludge scraping and sludge discharge mechanism 8 is connected to the mounting frame 3.

[0020] When using the sludge collection oxidation ditch wastewater treatment equipment of this utility model, the mobile frame 2 can move on the oxidation ditch 1 to treat wastewater in the oxidation ditch 1 at different positions. During wastewater treatment, the suction mechanism 5 sucks out the sludge from the bottom of the oxidation ditch 1 and then discharges it onto the filter belt 4 for filtration. During this process, the filter belt 4 is continuously driven to transport the intercepted sludge to the sludge scraping and discharge mechanism 8 for scraping and discharge. The water filtered by the filter belt 4 enters the water collection tank 6 and then returns to the interior of the oxidation ditch 1 through multiple drain pipes 7.

[0021] Both the driving roller and the driven roller are equipped with pulleys, which are connected by a synchronous belt. The driving roller is driven by a motor 9. By starting the motor 9, the driving roller rotates, and then the driven roller rotates synchronously under the transmission of the two pulleys and the synchronous belt, thereby driving the filter belt 4 to run.

[0022] The sludge suction mechanism 5 includes a sludge suction pump 501, a sludge suction pipe 502, and a sludge discharge pipe 503. Multiple sets of sludge suction pumps 501 are provided. The lower end of the sludge suction pipe 502 is located inside the oxidation ditch 1. The input ends of multiple sets of sludge suction pumps 501 are connected to the upper ends of the sludge suction pipe 502, and the output ends of multiple sets of sludge suction pumps 501 are equipped with sludge discharge pipes 503. After the multiple sets of sludge suction pumps 501 are started, they suck out the sludge from the oxidation ditch 1 through the sludge suction pipe 502, and then discharge it onto the filter belt 4 for filtration through the sludge discharge pipe 503.

[0023] A protective frame 10 is provided above the filter belt 4, and the sewage pipe 503 is located above the protective frame 10, with multiple sewage outlets 504 leading into the interior of the protective frame 10 on the sewage pipe 503. The protective frame 10 prevents the sludge sucked up by the suction mechanism 5 from overflowing from the top four sides of the filter belt 4, allowing the sludge to be fully filtered through the filter belt 4.

[0024] The enclosure frame 10 is connected to the mounting bracket 3 via a connecting block. The bottom of the enclosure frame 10 is provided with rollers 11, and multiple sets of rollers 11 are provided. The rollers 11 are designed to ensure that the bottom of the enclosure frame 10 makes rolling contact with the top of the filter belt 4, so that the enclosure frame 10 does not affect the operation of the filter belt 4. The rollers 11 also help to prevent sludge from overflowing.

[0025] The sludge scraping and discharge mechanism 8 includes a scraper strip 801 and a discharge slope plate 802. The discharge slope plate 802 is located below the output end of the filter belt 4. The discharge slope plate 802 is connected to the mounting frame 3, and the scraper strip 801 is located at the top of the upper end of the discharge slope plate 802. The scraper strip 801 contacts the bottom of the filter belt 4. When the sludge filtered by the filter belt 4 enters the scraper strip 801, the scraper strip 801 is tilted to scrape the sludge forward, and then it falls onto the discharge slope plate 802 and is discharged from the equipment.

[0026] This invention enables rapid sludge filtration by setting a filtration mechanism consisting of a mounting frame 3, an active roller, a driven roller, and a filter belt 4 on the top of a movable frame 2 on the oxidation ditch 1. The sludge intercepted on the filter belt 4 is quickly discharged at the sludge scraping and discharge mechanism 8. The sludge is discharged from the equipment simultaneously with the sewage treatment, so that the equipment operation is not affected by the weight of the sludge, which can effectively reduce energy consumption and improve sewage treatment efficiency.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
