Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] Please refer to Figures 1 - 4 , the present utility model provides a concrete production wastewater treatment device, including a collection box 1 for collecting and precipitating wastewater. An observation window 18 and a control panel 19 are installed on the outer side of the collection box 1. The water level inside can be conveniently observed through the observation window 18 for timely drainage, and the device can be conveniently operated through the control panel 19. A through water changing port 7 is provided at the bottom of the collection box 1, and a controllable valve is arranged inside the water changing port 7, so that the wastewater inside the collection box 1 can be discharged in time. At the upper end of the collection box 1, a through bottom cylinder 4, a middle cylinder 5 and an upper cylinder 6 are successively arranged from bottom to top through a fixing frame 2, and the bottom cylinder 4, the middle cylinder 5 and the upper cylinder 6 are arranged at intervals. The interval distance between the bottom cylinder 4, the middle cylinder 5 and the upper cylinder 6 is the same as the distance of the water passing cylinder 14, to avoid the situation that wastewater leaks out through the gap when flowing down. And the bottom cylinder 4 penetrates through the top of the collection box 1, so that the bottom cylinder 4 can conveniently introduce the wastewater directly into the collection box 1 for treatment. Reinforcing rods 3 are obliquely arranged on the outer side of the fixing frame 2 and connected to the collection box 1 to enhance the fixing effect and stability. The upper end of the upper cylinder 6 is arranged in an upward funnel shape to facilitate connection with an external wastewater conveying mechanism, and a solenoid valve 8 is installed at the inlet to conveniently close the wastewater conveyance in time for the user to control.

[0027] Both the outer sides of the middle cylinder 5 and the upper-end cylinder 6 are connected with mounting plates 9. The lower ends of the mounting plates 9 are connected with rotating shafts 10 through bearings. The upper ends of the mounting plates 9 are provided with motors 11 through protective boxes 12 and are connected with the rotating shafts 10. The protective boxes 12 are used to prevent waste water from affecting the motors 11. A plurality of water-passing cylinders 14 penetrating up and down are connected to the outer sides of the rotating shafts 10 through connecting plates 13, so that waste water passes through the water-passing cylinders 14. Sealing rings 15 are arranged at the upper and lower ends of the water-passing cylinders 14 to prevent waste water from flowing out through the side gaps. Filter cylinders 17 are installed inside the water-passing cylinders 14 through mounting plates 16. The filter cylinders 17 in the form of filter meshes are convenient for filtering impurities. The pore sizes of the filter cylinders 17 arranged at the upper and lower ends decrease sequentially from top to bottom, so that the impurities in the waste water can be filtered more completely, the generation of waste water impurities is reduced, and the filter cylinders 17 are conveniently installed through the mounting plates 16 and can be pulled out upwards, so that they are convenient to replace and clean.

[0028] Working principle: When in use, first connect the solenoid valve 8, the motor 11 and the control panel 19 to an external power supply, then connect the upper-end cylinder 6 to an external waste water conveying mechanism, and then drive the rotating shaft 10 to rotate by the motor 11, so that the water-passing cylinders 14 enter the inner parts of the bottom cylinder 4, the middle cylinder 5 and the upper-end cylinder 6. After the solenoid valve 8 is opened, waste water can enter the bottom cylinder 4, the middle cylinder 5 and the upper-end cylinder 6. When the waste water passes through the filter cylinders 17, the impurities in the waste water are removed. Two filter cylinders 17 are arranged up and down, so that the filtering effect is better. When driven by the motor 11 to rotate, different water-passing cylinders 14 can be replaced to enable the filter cylinders 17 inside to filter the waste water, and the filter cylinders 17 can be conveniently taken out upwards for replacement and cleaning. Subsequently, the filtered waste water enters the collection box 1 to complete the work.
