Description

Technical Field

[0001] This utility model relates to the field of construction wastewater treatment technology, specifically a wastewater treatment and reuse device. Background Technology

[0002] Construction wastewater refers to various types of sewage generated during the construction process, including all water pollution sources involved in the construction process and on the construction site, such as wastewater from concrete mixing, pouring, cleaning of mixers, pump trucks, and other equipment. Currently, the initial treatment of this wastewater requires filtration and sedimentation. Filtration often uses fixed-position filter screens for water filtration. However, after long-term use, these fixed screens are prone to clogging due to the accumulation of debris and suspended solids, affecting the filtration effect. As the deposits on the filter surface increase, the filtration efficiency gradually decreases. Accumulated impurities not only affect the filtration speed but also the effectiveness of subsequent treatment steps. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater treatment and reuse device to solve the problems mentioned in the background art.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Wastewater enters the filter cylinder from the bottom of the rotating pipe, and water enters the sedimentation tank through the filter holes of the filter cylinder. Impurities are filtered inside the filter cylinder, achieving preliminary solid-liquid separation. The rotating pipe drives the spiral blades to rotate, conveying the impurities in the filter cylinder upwards and discharging them, eliminating the need for manual cleaning of the impurities in the filter cylinder. The diluted and mixed flocculant is sent into the conveying chamber of the stirring shaft, and sprayed into the mixing tank through the rotating nozzle at the bottom of the conveying chamber, expanding the spraying range of the flocculant and making the contact between the flocculant and the wastewater more uniform. Water pump one draws water from the bottom of the mixing tank, and the water pressure drives the stirring shaft to rotate through the water bucket-type water wheel. The stirring shaft drives the stirring blades to stir the inside of the mixing tank. At the same time, water pump one draws out the wastewater from the bottom and sprays it into the mixing tank from the top, forming a water circulation flow, which further improves the mixing efficiency of flocculant and wastewater, facilitating rapid flocculation and sedimentation of wastewater.

[0025] It should be noted that in this embodiment, a controller and a timer are provided. The water pipe carrying domestic sewage is placed inside the rotating inlet pipe 8. Water enters the filter cylinder 7 from the bottom of the rotating pipe 8. Under the filtration of the filter cylinder 7, the water enters the sedimentation tank 3 through the filter holes of the filter cylinder 7. Impurities are filtered out inside the filter cylinder 7. The rotating pipe 8 drives the spiral blades 9 to rotate, and the spiral blades 9 transport the impurities inside the filter cylinder 7 upwards and discharge them. After settling inside the sedimentation tank 3, the water enters the mixing tank 4 through an overflow port on one side. The water pump inside sends the diluted and mixed flocculant into the conveying chamber 20, and sprays it into the mixing tank 4 through the nozzle 14 at the bottom of the conveying chamber 20. During this period, the water pump 11 pulls the bottom of the mixing tank 4 upward, and the water pressure drives the mixing shaft 6 to rotate through the water bucket type water wheel 13. The mixing shaft 6 rotates and sprays the water through the nozzle 14 to stir the inside of the mixing tank 4, thereby fully mixing the flocculant and the sewage. After the water pump 11 pulls out the sewage at the bottom, it sprays it from the top to improve the mixing efficiency and facilitate its rapid flocculation and sedimentation.

[0026] In one embodiment, a top cover 2 is fixedly connected to the top of the processing box 1, and the water pump 11 and the filter cylinder 7 are both fixedly connected to the top cover 2. A bracket is fixedly connected to the top of the top cover 2, and the rotating tube 8 is rotatably connected to the bracket. A servo motor 10 for driving the rotating tube 8 to rotate is fixedly connected to the outside of the bracket.

[0027] It should be noted that in this embodiment, the output end of the servo motor 10 and the outer side of the rotating tube 8 are both fixed with synchronous pulleys, and the two synchronous pulleys are connected by synchronous belt drive. The servo motor 10 drives the rotating tube 8 to rotate inside the filter cylinder 7 through the synchronous belt assembly. A funnel is installed in the middle of the upper support of the rotating tube 8, and the bottom of the funnel is inserted into the rotating tube 8 to introduce water into the rotating tube 8. The servo motor 10 drives the spiral blade 9 to rotate slowly through the rotating tube 8, so as to facilitate the automatic discharge of filtered impurities.

Water enters through the top of the rotating pipe 8 and flows into the filter cylinder 7 through the bottom of the rotating pipe 8. The water is discharged through the filter holes of the filter cylinder 7. Impurities are filtered by the filter holes of the filter cylinder 7 and remain inside the rotating pipe 8. The rotating pipe 8 drives the spiral blades 9 to transport the impurities inside the rotating pipe 8 upward and discharge them through the drain pipe 18. In addition, the sedimentation tank 3 is equipped with spray pipes corresponding to the filter cylinder 7, which can be used for backwashing.

[0031] It should be noted that in this embodiment, water pump 11 draws water out of the mixing tank 4 and sends it into the water pan 12. The drain outlet of water pump 11 is located at the edge of the water pan 12. Water pressure drives the water bucket type water wheel 13 to rotate, and water is discharged into the mixing tank 4 through the spray pipe 16. The water bucket type water wheel 13 drives the stirring shaft 6 to rotate. The stirring shaft 6 stirs the inside of the mixing tank 4, and water pump 11 circulates and draws water from the bottom upwards to prevent uneven stirring at the bottom.
