Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a sewage filtering and recycling device for a construction site. Background Art

[0002] During the construction process, construction activities in a certain area of ​​the construction site are relatively independent and closed, which will lead to a large amount of waste of domestic water and accumulation of natural rainwater and poor drainage within the construction fence.

[0003] The construction water used in traditional construction sites is mostly tap water and groundwater. The wastewater generated during the construction process is discharged through flood drainage channels, and there is no further treatment of the sewage on the construction site. If the sewage on the construction site is not treated, it will have a certain impact on nature and people’s living environment, and it will waste water resources, which is not conducive to environmental protection and resource conservation.

[0004] Reference authorization announcement number: CN216320208U Chinese authorized patent: A green building sewage treatment and recycling device. This utility model can clean the filter without taking it out, which will not reduce the sewage treatment efficiency. At the same time, it can filter larger and smaller debris in the sewage separately, thereby improving the filtering effect of debris in the sewage. Secondly, it will not allow the sewage to directly rush to the filter, thereby extending the service life of the filter.

[0005] However, during the process of cleaning the filter, large particles of impurities will still accumulate on the surface of the filter, and the large particles of impurities cannot be quickly cleaned off the surface of the filter. In order to ensure the filtering effect of the filter during sewage filtration, the filter must either be cleaned by staff, which increases the labor intensity of the staff, or the filter must be continuously cleaned by a high-pressure nozzle, which wastes water resources.

[0008] In a further embodiment, a mounting rod is fixed to the inner wall of the filter box, a stepper motor is mounted on the surface of the mounting rod, and a lifting screw is fixed to the output end of the stepper motor.

[0009] In a further embodiment, the outer wall of the lifting screw is threadedly connected to a connecting rod fixedly connected to the cleaning frame, and the outside of the stepper motor is provided with a waterproof cover fixedly connected to the mounting rod.

[0010] In a further embodiment, a water inlet is provided on the top of the filter box, and a water inlet hopper is fixed in the water inlet on the top of the filter box, and a plurality of diverter plates are fixed on the inner wall of the filter box.

[0011] In a further embodiment, support rods for supporting the filter plates are fixed to inner walls on both sides of the filter box, and a sealing door is installed on the filter box.

[0012] In a further embodiment, a water inlet hole is formed on an outer wall of the guide plate on a side away from the scraper plate, and a telescopic hose extending to the outside of the filter box is installed in the water inlet hole of the guide plate.

[0013] Technical effects and advantages of the utility model:

[0014] The construction site sewage filtering and recycling device can filter construction sewage through the filter plate, which is convenient for recycling sewage. At the same time, the motor is driven to drive the scraper to move, so as to automatically clean the large particles of impurities on the surface of the filter plate, avoiding manual cleaning by the staff.
