Description

Technical Field

[0001] The invention relates to the technical field of construction wastewater, and in particular to an environmentally friendly construction wastewater recycling device and method. Background Art

[0002] Construction wastewater is wastewater containing various pollutants generated during the construction process of a construction project. Construction wastewater usually contains a large amount of usable water resources. If it is discharged directly, it will not only waste water resources, but also cause environmental pollution. Therefore, it is necessary to treat construction wastewater through wastewater recycling equipment; However, when using the filter plate inside the wastewater recycling device to filter the wastewater, the filter plate is in a static state, which will result in a slow separation rate of solid impurities and wastewater. If a large amount of solid impurities accumulate on the filter plate and block the filter holes of the filter plate, the wastewater will not be able to pass through the filter plate for effective purification. Therefore, how to solve this problem is what we need to consider. Summary of the invention

Through the coordination of structures such as a lever, a spring and a cam, the filter plate can be shaken up and down, thereby accelerating the separation efficiency of solid impurities and wastewater and preventing solid impurities from accumulating on the filter plate and affecting the filtering effect of the filter plate.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: An environmentally friendly construction wastewater recycling device comprises a first shell, an outer side wall of the first shell is fixedly connected to a second shell, a lower end of the first shell is fixedly connected to a plurality of supporting legs, an upper end of the first shell is fixedly connected to a water inlet pipe, a side wall of the first shell is provided with a discharge port, a shakeable filter plate is arranged inside the first shell, an inner bottom of the first shell is rotatably connected to a stirring shaft, a plurality of stirring rods are fixedly connected to the outer wall of the stirring shaft, a side wall of the first shell is fixedly connected to a medicine inlet pipe, an inner bottom of the second shell is rotatably connected to a rotating shaft, an outer wall of the rotating shaft is fixedly connected to two fixing rods, opposite ends of the two fixing rods are fixedly connected to protective shells, ultraviolet lamps are installed in the two protective shells, a water pump is installed at the upper end of the second shell, a water inlet end of the water pump is communicated with the inside of the first shell, a water outlet end of the water pump is communicated with the inside of the second shell, a water outlet pipe is fixedly connected to the lower end of the second shell, and a driving mechanism for driving the filter plate to shake is arranged inside the first shell.

[0005] Preferably, the driving mechanism includes two fixed plates respectively fixedly connected to the inner walls on both sides of the first shell, the lower end of the filter plate is fixedly connected to two push rods, the lower ends of the two push rods pass through the corresponding fixed plates, the outer walls of the two push rods are sleeved with springs, the two ends of the two springs are elastically connected to the upper ends of the corresponding fixed plates and the lower end of the filter plate, a transmission shaft is rotatably connected between the inner walls on both sides of the first shell, two cams are fixedly connected to the transmission shaft, and the two cams cooperate with the corresponding push rods.

[0006] Preferably, a first motor is mounted on the outer side wall of the first shell, and a terminal end of an output shaft of the first motor extends into the interior of the first shell and is fixedly connected to one end of a transmission shaft.

[0010] The present invention also proposes an environmentally friendly construction wastewater recycling method, comprising the following steps: S1. When in use, firstly, waste water is injected into the first housing through the water inlet pipe, and then the first motor can be started. After the first motor is started, it will drive the transmission shaft to rotate, thereby causing the two cams to rotate. During the rotation process, when the two cams contact the corresponding push rods, the filter plate will be pushed up, and when the two cams are separated from the corresponding push rods, the filter plate will move down under the elastic action of the two springs, so that the two cams continue to rotate, causing the filter plate to shake up and down; S2.
