Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sedimentation device for wastewater treatment. 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 the daily lives of ordinary people.

[0003] However, some existing wastewater treatment sedimentation devices rely on long-term settling to allow sediment in the mixed liquid to settle to the bottom of the device. But when the waste liquid to be treated is continuously added to the device, the original clear sediment will become turbid again, affecting the efficiency of wastewater treatment. At the same time, it is not convenient to filter and collect large particulate impurities in the wastewater. Therefore, we propose a sedimentation device for wastewater treatment to solve the above problems. Utility Model Content

It is equipped with a fixed sewage pump 12, a filter screen 3 to filter large particles of impurities in the sewage, and an arc-shaped guide plate 6 to slowly inject water. The water purification agent is discharged into the sewage tank 1 through the guide cover 14 and the L-shaped pipe 13. The motor 9 is started to drive the stirring rod 8 to stir. The drain pump 10 discharges the treated sewage, and the sewage pump 12 discharges the sediment. It can achieve the effect of slow water injection, avoiding the original sediment and clear liquid from becoming turbid again when adding the waste liquid to be treated, thus increasing the efficiency of the work. It can filter and collect large particles of impurities in the sewage, avoiding the clogging of the sewage pump 12. It can suck the excessive sediment to the outside. The triangular plate 11 further improves the convenience of cleaning sediment.

[0021] In this embodiment, specifically: a triangular plate 11 is fixedly connected to the bottom inner wall of the sewage tank 1, and an L-shaped pipe 13 is connected to and fixed to the right side of the sewage tank 1.

[0022] In this embodiment, specifically: the top end of the L-shaped tube 13 is connected to and fixed with a flow guide shroud 14, the right side of the collection box 2 extends to the outside of the sewage tank 1, the sewage tank 1 is slidably sleeved on the outside of the collection box 2, and the top of the collection box 2 is fixedly connected with a first rectangular block 15.

[0023] In this embodiment, specifically: the first rectangular block 15 is threadedly connected to the sewage tank 1 by the first bolt 16, and two second rectangular blocks 17 are fixedly connected to the top of the filter screen 3;

[0024] In this embodiment, specifically: the second rectangular block 17 is threadedly connected to the collection box 2 by the second bolt 18, and a support block 19 is fixedly connected to the left side of the sewage tank 1;

[0025] In this embodiment, specifically: the top of the support block 19 is slidably connected to the bottom of the collection box 2, and the control panel 20 is fixedly connected to the front side of the sewage tank 1;

[0026] In this embodiment, specifically: a handle 21 is fixedly connected to the right side of the collection box 2, and support legs 22 are fixedly connected to the four corners of the bottom of the sewage box 1.

[0027] In operation, this utility model works as follows: Wastewater is discharged into the wastewater tank 1 through valve 7. The filter screen 3 filters large particles of impurities from the wastewater. The filtered wastewater falls through the drain outlet 4 onto the top of the arc-shaped guide plate 6, which acts as a buffer. The wastewater slides downwards along the outer side of the arc-shaped guide plate 6, forming a water curtain, thus achieving a slow water injection effect. The water purification agent is discharged into the wastewater tank 1 through the guide hood 14 and the L-shaped pipe 13. The motor 9 is started, driving the stirring rod 8 to rotate and perform stirring, achieving efficient separation of the wastewater. Sediments in the wastewater move downwards under gravity. At this time, the drain pump 10 and the sewage pump 12 are started. The drain pump 10 discharges the treated wastewater, and the sewage pump 12 discharges the sediment. When large particles of impurities need to be removed from the collection box 2 for cleaning, the first bolt 16 is rotated in the opposite direction to separate it from the sewage tank 1. The handle 21 is then held to remove the collection box 2 for cleaning. When the filter screen 3 is damaged and needs to be removed for replacement, the second bolt 18 is rotated in the opposite direction to separate it from the collection box 2. The filter screen 3 is then removed for replacement. This constitutes a sedimentation device for sewage treatment, which can achieve the effect of slow water injection, avoiding the original sediment and clear liquid from becoming turbid again when the waste liquid to be treated is added. This increases the efficiency of the work, can filter and collect large particles of impurities in sewage, avoids clogging of the sewage pump 12, and can suck excessive sediment to the outside. The triangular plate 11 further improves the convenience of cleaning sediment.
