Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an environmentally friendly and efficient high-concentration industrial wastewater treatment device. Background Art

[0002] Industrial wastewater is a product of industrial production. Most industrial production will produce wastewater. These industrial wastewaters cannot be discharged directly and need to be treated with corresponding purification measures before they can be discharged. When treating some high-concentration industrial wastewater, agents are usually added to the wastewater (the agents are flocculants, which mainly remove impurities such as suspended matter and colloids in the wastewater). The impurities in the wastewater are formed into lumps by mixing, and then the wastewater is filtered to purify the wastewater so that the wastewater meets the discharge standards. Some current wastewater treatment devices mainly include mixing and filtration to remove impurities in the sewage. However, the filter net is mostly set at the drain valve. This filtering method can easily block the drain valve port, and the installation position of the drain valve is difficult to clean. To this end, we provide an environmentally friendly and efficient high-concentration industrial wastewater treatment device to solve the above problems. Utility Model Content

The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0019] Working principle: When using the wastewater treatment device, the user can introduce the wastewater into the tank body 1 above the filter plate 7. The wastewater can be filtered for the first time at the filter plate 7, and then the solenoid valve 9 is opened to allow the wastewater to flow to the bottom of the tank body 1. During the falling process of the wastewater, the external pump is connected to the dosing valve 14 to inject the medicine into the inner cavity of the tank body 1, and the medicine can be sprayed in a ring shape through the annular nozzle 15. The medicine and the wastewater fall at the same time, so that the medicine and the wastewater are evenly mixed. In this process, the motor 2 is started. The output speed of the motor 2 can be reduced by the reducer 3, and the shaft 4 and the stirring blade 5 are driven to rotate. Due to the stirring The mixing blade 5 is tilted to allow the water to move obliquely while rotating, thereby making the mixing of water and the agent more complete and the agglomeration of impurities in the wastewater more thorough. After the impurities in the wastewater are agglomerated, the solenoid valve 9 can be closed and the water pump 11 can be started. The water pump 11 can drive the wastewater to be transported through the connecting pipe 10, so that the wastewater can flow back to the top of the filter plate 7 for secondary filtration, so that the agglomerated impurities after mixing can be intercepted by the filter plate 7. When the wastewater in the tank body 1 below the isolation bucket 8 is drained, the solenoid valve 9 can be opened to allow the water to flow to the bottom of the tank body 1 again. At this time, the drain valve 6 can be opened to collect the purified water.
