Description

Technical Field

[0001] This invention relates to the field of building structure technology, specifically a tank washing water recycling system. Background Technology

[0002] With the rapid development of the construction industry, various concrete buildings have sprung up in urban areas in recent years, leading to a growing demand for ready-mixed concrete and the widespread application of ready-mixed concrete mixer trucks. However, existing concrete transport trucks all leave some residual material after discharging. To prevent the residual concrete from solidifying in the equipment and to keep the equipment clean, a large amount of water is needed for rinsing. The wastewater from rinsing contains a large amount of insoluble building materials such as cement and sand. If discharged into rivers without proper treatment, it will cause serious pollution and waste a lot of tap water and concrete materials. Therefore, the disposal of residual material after cleaning mixer trucks and pump trucks has become a major headache for every construction site. Summary of the Invention

That is, after concrete is poured at various construction sites, the remaining concrete in the tank trucks and pump trucks is washed and separated in the separation chamber 5. The wastewater enters the purification tank, and after purification treatment, it is recycled. The separated solid material enters the interior of the material chamber 7 for centralized processing.

[0030] In this embodiment, the purification tank and the separation chamber 5 are connected by a transmission pipe 9. A water pump 2 is installed at the lower end of the purification tank, and the water pump 2 is connected to the separation chamber 5 via a water outlet pipe 8. Specifically, one end of the water pump 2 is connected to the water outlet pipe 8, and the other end of the water outlet pipe 8 is located at the upper end of the separation chamber 5. Multiple nozzles are installed at the end of the water outlet pipe 8 at the upper end of the separation chamber 5 for spraying water into the interior of the separation chamber 5. Specifically, the purification tank includes a tertiary purification tank 1, a secondary purification tank 3, and a primary purification tank 4, arranged sequentially. It is worth noting that the primary purification tank 4 is connected to the separation chamber 5 via the transmission pipe 9, and the separation chamber 5 is connected to the tertiary purification tank 1 via the water outlet pipe 8. That is, wastewater undergoes progressive purification through the primary purification tank 4, the secondary purification tank 3, and the tertiary purification tank 1, meaning the water in the tertiary purification tank 1 can be recycled.

[0031] Furthermore, an inclined concrete pad is provided at the lower end of the separation chamber 5, wherein the slope of the inclined concrete pad is not less than 5%. In this embodiment, the slope of the inclined concrete pad is set to 5%, and the thickness of the inclined concrete pad is set to 100mm. Meanwhile, a screen 6 is provided at the upper end of the separation chamber 5, and a vibrator 11 and an elastic base 12 are provided at the lower end of the screen 6. It is worth noting that the lower end of the screen 6 is connected to the lower end of the separation chamber 5 through the elastic base 12, and the vibrator 11 is located on the side of the elastic base 12 and is electrically connected to the controller 18.

[0032] In this embodiment, the interior of the transmission pipe 9 is connected to the interior of the separation chamber 5 and the interior of the material chamber 7. The separation chamber 5 and the material chamber 7 are interconnected, and a discharge port 13 is provided between them. Specifically, an electric baffle is installed on the discharge port 13, and a first valve control switch 22 is installed on the electric baffle. A first weight sensor 21 is installed inside the separation chamber 5. This first weight sensor 21 is used to acquire the weight information of the material passing through the screen 6, and the first weight sensor 21 and the first valve control switch 22 are electrically connected via a controller 18.

[0033] In this embodiment, a material hopper 10 is provided inside the material chamber 7, wherein the upper cross-sectional area of ​​the material hopper 10 is larger than the lower cross-sectional area, i.e., the material hopper 10 has a structure that is wider at the top and narrower at the bottom. Specifically, the lower end of the material hopper 10 is connected to the bottom of the material chamber 7 through a support base 17, and a protective cover 16 is provided at the upper end of the material hopper 10, while a movable base plate 14 is provided at the lower end of the material hopper 10. Further, a guide portion 15 is provided on the inner side of the material hopper 10, and the lower end of the guide portion 15 is connected to the side of the movable base plate 14. It is worth noting that a water guide hole is provided at the lower end of the guide portion 15, and the water guide hole is connected to the separation chamber 5 through the support base 17. At the same time, an included angle α is provided between the end of the guide portion 15 and the side of the movable base plate 14, and the included angle α satisfies: 90° < α < 180°. In this embodiment, the included angle α is set to 140°.

[0034] Furthermore, a second weight sensor 19 is provided at the lower end of the movable base plate 14. The second weight sensor 19 is used to obtain the weight information of the material at the upper end of the movable base plate 14. At the same time, a second valve brake switch 20 is installed on the movable base plate 14. The second valve brake switch 20 is electrically connected to the second weight sensor 19 through the controller 18.

[0035] Specifically, the usage process of the tank washing water recycling system in this embodiment is as follows:

[0036] After concrete is poured at various construction sites, the remaining concrete in the concrete mixer trucks and pump trucks is cleaned in the separation chamber 5. During the cleaning process, the controller 18 starts the water pump 2 and the vibrator 11. The water pump 2 draws circulating water from the tertiary purification tank 1 to clean the material in the separation chamber 5. At the same time, the vibration of the vibrator 11 allows the material to be cleaned more quickly. The first weight sensor 21 temporarily acquires the weight information of the material passing through the screen 6. When the ratio between the acquired material weight information and the initial material weight information reaches a preset ratio, the controller 18 activates the first valve control switch 22, and the cleaned material enters the material hopper 10. The sewage in the separation chamber 5 and the sewage in the material hopper 10 are guided by the transmission pipe 9 into the primary purification tank 4 for water purification treatment.

[0037] After the cleaned material enters the material hopper 10, the second weight sensor 19 continuously acquires the material weight information at the upper end of the movable base plate 14. When the material weight reaches the preset weight information, the controller 18 activates the second valve brake switch 20. At this time, the operator can collect the cleaned material at the lower end of the material chamber 7. It is worth noting that the cleaned material can also be collected directly.
