The invention provides a sewage treatment device for industrial sewage. It has the following beneficial effects:

(1) This sewage treatment device for industrial sewage uses a filter motor to drive a metal frame to rotate and stir the sewage. The large impurities in the sewage are blocked by the metal frame and attached to the surface of the metal frame. The metal frame is affected by water during the rotation. The resistance pushes the elastic plate to bend, and the arc plate moves with the elastic plate. After the arc plate moves to the outside of the lifting column, the lifting column is no longer blocked by the arc plate. The lifting column descends along the lifting groove to block the elastic plate. The inside of the filter barrel After the sewage has filtered large particles of impurities, take the sewage out of the filter barrel and pull the limit block upward until the lifting column moves above the elastic plate and arc plate. The curved elastic plate is not blocked by the lifting column due to its own elasticity. The initial direction deflection, the deflection of the elastic plate drives the metal frame to oscillate. During the vibration of the metal frame, the large particle impurities on the surface fall off to the bottom of the filter barrel, which can easily remove the large particle impurities attached to the surface of the metal frame after the sewage is discharged. Reduce the difficulty of cleaning equipment.

(2) The sewage treatment device for industrial sewage moves the lifting box upward until the air inlet moves above the sewage. The air enters the interior of the lifting box from the air inlet. The lifting box moves downward and the lifting box enters. After the sewage is inside, the sewage enters the inside of the lifting box from the air inlet. The air inside the lifting box is squeezed out by the sewage to the outside of the lifting box. This can increase the oxygen content in the sewage during the sewage filtration process and prevent the sewage from being internalized during the filtration process. Microorganisms carry out anaerobic reactions to produce unpleasant odors, optimizing the environment during sewage treatment in garbage disposal stations.

(3) In this sewage treatment device for industrial sewage, when the sewage enters the inside of the lifting box, large impurities are blocked by the filter and adhere to the filter. The sewage inside the lifting box rises with the lifting box. When the longitudinal groove rises to At the drainage channel, the sewage inside the lifting box flows into the water storage box through the longitudinal groove and the drainage channel, which can discharge the sewage filtered out of large particle impurities during the sewage treatment process, improving the efficiency of sewage treatment.

(4) In this sewage treatment device for industrial sewage, when the lifting box is lifted and lowered, the sewage impacts the large impurities attached to the surface of the filter. When the lifting box enters the sewage from outside the sewage, the air inside the lifting box passes through the air inlet. The air is discharged into the sewage. When the air is discharged from the inside of the lifting box through the air inlet, it impacts the large particles of impurities attached to the surface of the filter. The large particles of impurities attached to the surface of the filter can be cleaned using various methods of water flow and airflow impact to avoid large particles. Impurities clogging the filter reduce the efficiency of sewage discharge.

(5) This sewage treatment device for industrial sewage filters out large particles of impurities through the filter screen and lifting box into the water storage box, and pushes the cover plate to move in the direction of the filter barrel until the cover plate moves the water storage box The top is sealed. At this time, the sealing plate compresses the return spring and blocks the drainage channel. After the water storage box is completely sealed, the sewage inside begins an anaerobic reaction to remove organic matter, which improves the depth of sewage treatment and can remove large particle impurities and organic matter in the sewage. , reducing the difficulty of subsequent treatment of sewage.

(6) This sewage treatment device for industrial sewage uses the resistance of sewage when the metal frame rotates to push the elastic plate and the metal frame to deflect. After the sewage treatment is completed, the deflected elastic plate drives the metal frame to vibrate to break away the attached large particle impurities. It improves the energy utilization efficiency of the equipment and can use the resistance when stirring and filtering sewage to assist in removing impurities attached to the surface of the equipment.
