Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a high-efficiency magnetic flocculation sedimentation sewage treatment device. Background Technique

[0002] Magnetic flocculation is a new sewage treatment technology, whose full name is magnetic flocculation technology. By introducing magnetic loading substances (usually magnetic powder, such as Fe3O4) into the traditional flocculation sedimentation process, the flocs generated by flocculation are effectively combined with the loading substances, thereby enhancing the flocculation effect, increasing the specific gravity of the flocs, and accelerating the sedimentation speed of the flocs, so as to rapidly purify the water body.

[0003] During the magnetic flocculation sedimentation of municipal sewage, after the sludge pump pumps out the flocs at the bottom of the pool from the sludge pool, there will still be residual magnetic flocculation precipitates at the bottom of the pool, which will enter the water body and soil with the water flow, causing environmental pollution. For this reason, we propose a high-efficiency magnetic flocculation sedimentation sewage treatment device. Content of the Utility Model

At the bottom of the inner wall of the device main body 1, a dirt removal component 2 is provided. The dirt removal component 2 includes an inclined plate 201, and the inclined plate 201 is fixedly connected to the bottom of the inner wall of the device main body 1. A scraping groove 202 is formed at the top of the inclined plate 201. On one side of the inner wall of the device main body 1, a placement groove 203 is formed. On one side of the placement groove 203, an electric push rod 204 is fixedly connected. One end of the electric push rod 204 is fixedly connected to a scraping plate 205. A convex plate 206 is fixedly connected to the bottom of the scraping plate 205. On the other side of the inner wall of the device main body 1, a discharge port 3 is formed. One end of the discharge port 3 is fixedly communicated with a pipeline 4. One end of the pipeline 4 is fixedly communicated with a sludge pump 5. When the sewage enters the device main body 1, the magnetic flocs start to sink. Due to the setting of the inclined plate 201, the sedimentation speed is accelerated. The magnetic flocs slide down along the inclined plate 201 and gradually accumulate at the bottom. When the magnetic flocs accumulate to a certain amount, the sludge pump 5 pumps the sludge out of the discharge port 3 through the pipeline 4. And the remaining magnetic flocs are pushed by the electric push rod 204 to move the scraping plate 205 and the convex plate 206 at the bottom along the scraping groove 202, and the remaining magnetic flocs deposited on the inclined plate 201 are pushed to the discharge port 3.

At the same time, when the clear water in the device main body 1 passes through the filter plate 6, the remaining suspended matters are further removed. Driven by the first motor 802, the filter plate 6 realizes slight vibration through the transmission mechanism of the shaking plate 803, the movable rod 804 and the rolling ball 805, which helps to prevent the filter holes from being blocked and improves the filtering efficiency. The clear water filtered by the filter plate 6 is discharged from the device through the discharge pipe 7. During the vibration of one end of the filter plate 6 in the movable groove 9, the seal between the filter plate 6 and the inner wall of the device main body 1 is maintained through the elastic sleeve 10, so that the suspended matters will not float up through the gaps.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the sewage to be treated is guided into the reaction tank 11. In the reaction tank 11, magnetic powder is added to the sewage through the magnetic powder cartridge 12, and the stirring device 13 is started.

When the magnetic flocs accumulate to a certain amount, the sludge pump 5 pumps the sludge out from the discharge port 3 through the pipeline 4, while the remaining magnetic flocs are pushed by the electric push rod 204 to move the scraping plate 205 and the convex plate 206 at the bottom along the scraping groove 202, pushing the remaining magnetic flocs deposited on the inclined plate 201 to the discharge port 3. At the same time, when the clear water in the device main body 1 passes through the filter plate 6, the remaining suspended substances are further removed. The filter plate 6 is driven by the motor one 802 and realizes slight vibration through the transmission mechanism of the rocking plate 803, the movable rod 804 and the rolling ball 805, which helps to prevent the filter holes from being blocked and improves the filtration efficiency. The clear water filtered by the filter plate 6 is discharged from the device through the discharge pipe 7.
