[0002] Wastewater treatment involves using physical, chemical, and biological methods to treat groundwater, purify it, reduce pollution, and ultimately achieve wastewater recycling and reuse, making full use of water resources.

[0003] Most existing sewage treatment equipment uses sewage collection tanks buried underground and typically employs filtration to collect and treat sewage. However, impurities filtered from the sewage accumulate on the filter plates. If stored for a long time, this often leads to filter plate blockage, slowing down the filtration process and increasing the workload during subsequent cleaning, making it inconvenient to use. Utility Model Content

[0004] Therefore, this utility model provides a sewage treatment device for municipal engineering, which solves the problem that most sewage treatment devices use sewage collection tanks buried underground and usually use filtration to collect and treat sewage. However, the impurities filtered in the sewage will be stored on the filter plate. If stored for a long time, it will often cause the filter plate to become blocked, the filtration will be slow, and the workload will be increased during the later cleaning and treatment, making it inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sewage treatment device for municipal engineering, comprising a housing, wherein a sewage treatment mechanism is provided inside the housing;

[0006] The wastewater treatment mechanism includes a filter cylinder disposed inside a housing. A first collar and a second collar are sleeved on the outside of the filter cylinder via bearings. A first fixing plate is fixedly mounted on one side of the first collar and is fixedly connected to the inner wall of the housing. A second fixing plate is fixedly mounted on the top of the second collar and is fixedly connected to the inner wall of the housing. An inner support ring is connected to the inner wall of the filter cylinder via bearings. A sleeve is fixedly mounted on one side of the inner support ring, and a scraper is fixedly mounted on the other side of the inner support ring. A third gear is fixedly mounted on the outside of the sleeve. A second motor is fixedly mounted on one side of the housing. A second drive shaft is fixedly connected to the output end of the second motor. A second gear is fixedly connected to one end of the second drive shaft, and the second gear meshes with the third gear.

A second motor 7 is fixedly provided on one side of the housing 1. A second transmission shaft 16 is fixedly connected to the output end of the second motor 7. A second gear 17 is fixedly connected to one end of the second transmission shaft 16. The second gear 17 meshes with the third gear 23. A baffle 12 is fixedly provided inside the filter cylinder 9. An inclined baffle 8 is fixedly provided inside the housing 1. A water inlet pipe 6 is fixedly provided on one side of the housing 1. The water inlet pipe 6 passes through the inner support ring 18. A drain pipe 4 is fixedly provided on one side of the housing 1.

[0027] In this embodiment, sewage is injected through the inlet pipe 6 and falls into the filter cylinder 9. The filter cylinder 9 intercepts impurities in the sewage. The filtered water falls onto the inclined baffle 8 and slides down at an angle, allowing the water to be discharged through the drain pipe 4. The baffle 12 intercepts impurities. The filter cylinder 9 is controlled to rotate until the baffle 12 rotates to the top position and no longer intercepts impurities. Then, the second motor 7 is started. The second motor 7 controls the second drive shaft 16 to rotate. The second drive shaft 16 drives the second gear 17 to rotate. The second gear 17 drives the third gear 23 to rotate. The third gear 23 drives the sleeve 22 to rotate. The sleeve 22 drives the inner support ring 18 to rotate. The inner support ring 18 drives the scraper 13 to rotate. The scraper 13 pushes the impurities inside the filter cylinder 9 to rotate and move, allowing the impurities to be discharged from one side of the filter cylinder 9.

[0028] To achieve the rotation, the device employs the following technical solution: a toothed ring 19 is fixedly sleeved on the outside of the filter cylinder 9; a first motor 5 is fixedly mounted on one side of the housing 1; a first transmission shaft 14 is fixedly connected to the output end of the first motor 5; the first transmission shaft 14 passes through the side wall of the housing 1 and is connected to the side wall of the housing 1 via a bearing; one end of the first transmission shaft 14 is connected to the second fixed plate 21 via a bearing; a first gear 15 is fixedly sleeved on the outside of the first transmission shaft 14; the first gear 15 meshes with the toothed ring 19; when the filtration of the filter cylinder 9 slows down, the first motor 5 is started; the first motor 5 controls the rotation of the first transmission shaft 14; the first transmission shaft 14 drives the first gear 15 to rotate; the first gear 15 drives the toothed ring 19 to rotate; the toothed ring 19 drives the filter cylinder 9 to rotate; the first motor 5 controls the first transmission shaft 14 to rotate in both directions, causing the filter cylinder 9 to rotate counterclockwise and clockwise by a certain angle; at this angle, the filter holes on the filter cylinder 9 are not blocked, facilitating continued filtration.

[0029] In order to achieve the purpose of removing impurities, the device adopts the following technical solution: a slag discharge shell 2 is fixedly provided on one side of the shell 1. Impurities are discharged from one side of the filter cylinder 9 and fall onto the slag discharge shell 2. The impurities are discharged through the slag discharge shell 2, which is convenient for cleaning.

[0031] The usage process of this utility model is as follows: When using this utility model, sewage is injected through the inlet pipe 6 and falls into the filter cylinder 9. The filter cylinder 9 intercepts impurities in the sewage, and the filtered water falls onto the inclined baffle 8 and slides down at an angle, allowing the water to be discharged through the drain pipe 4. The baffle 12 intercepts impurities. When the filtration of the filter cylinder 9 slows down, the first motor 5 is started. The first motor 5 controls the first drive shaft 14 to rotate, which in turn drives the first gear 15 to rotate. The first gear 15 drives the gear ring 19 to rotate, which in turn drives the filter cylinder 9 to rotate. The first motor 5 controls the first drive shaft 14 to rotate in both directions, causing the filter cylinder 9 to rotate counterclockwise and clockwise by a certain angle. This angle... The filter holes on the filter cylinder 9 are not blocked, allowing for continued filtration. When impurities need to be cleaned, the filter cylinder 9 is first rotated so that the baffle 12 rotates to the top position and no longer intercepts impurities. Then, the second motor 7 is started, which controls the second drive shaft 16 to rotate. The second drive shaft 16 drives the second gear 17 to rotate, which in turn drives the third gear 23 to rotate. The third gear 23 drives the sleeve 22 to rotate, which in turn drives the inner support ring 18 to rotate. The inner support ring 18 drives the scraper 13 to rotate, which pushes the impurities inside the filter cylinder 9 to rotate and move, causing the impurities to be discharged from one side of the filter cylinder 9 and fall onto the slag discharge shell 2. The impurities are then discharged through the slag discharge shell 2 for easy cleaning.
