[0014] The present invention provides a domestic sewage treatment device with filtering function. It has the following beneficial effects: (1) The present invention, through the setting of the filtering device, enables the rotating motor to cooperate with the crushing rod to crush the impurities in the sewage flowing out of the water inlet, so that the impurities in the sewage can be uniformly crushed and processed, thereby preventing various impurities from being unable to be processed and accumulating on the filter screen to cause the filter screen to be blocked. The reciprocating threaded rod cooperates with the reciprocating block to drive the scraper block to reciprocate and scrape off the solid impurities on the surface of the filter screen. The scraper block cooperates with the extrusion block, the opening and closing plate, the limiting block, the A elastic telescopic rod, the vibration plate and the collection box, so that the solid impurities on the scraper block can be removed from the device by the opening and closing plate. The vibration generated by the vibration plate makes the residual impurities on the scraper block fall into the collection box more effectively. Then, the detachable setting of the collection box improves the efficiency of filtering impurity processing.

[0015] (2) The present invention, through the setting of the filtering device, enables the rotating module to cooperate with the rotating knob, the rotating rod and the lifting rod, so that the poking block on the lifting rod moves up and down. The poking block moves up and down and continuously extends out of the leakage groove opened in the filter net, thereby separating the impurities stuck in the filter net and improving the filtering effect of the filter net.

[0016] (3) The present invention, through the setting of the dosing device, allows the drug to enter the stirring box from the drug inlet, and then the poking block moves up and down in coordination with the A lifting block and the push rod to move up and down, so that the thread groove provided on the push rod pushes the thread in the stirring blade to rotate, thereby achieving the effect of stirring the drug by the stirring blade, preventing the drug from agglomerating and not being dissolved, thereby reducing the chemical reaction between the drug and the sewage. Under the action of the centrifugal force generated by the rotation of the stirring blade, in coordination with the leakage groove provided on the circumferential surface of the stirring box, the drug in the stirring box can be evenly sprayed to the surroundings, thereby improving the effect of the fusion of the drug and the sewage.

[0017] (4) The present invention, through the setting of the dosing device, allows part of the liquid to enter the air pressure tube through the air holes opened on the air pressure tube, and then the up and down movement of the poking block drives the pushing rod to move up and down to achieve the effect of applying pressure. When the pushing rod reaches the maximum descending degree, the baffle under the pushing rod will block the air hole to prevent the liquid from flowing in and affecting the effect of applying pressure. At the same time, the pushing rod applies pressure to the inside of the air pressure tube so that the liquid in the air pressure tube contacts the squeezing rod. The squeezing rod is pushed by the liquid, so that the arc-shaped spring sheet at the top of the squeezing rod contacts the arc-shaped spring sheet at the bottom of the upper and lower rods to produce an up and down shifting effect. Then, the water spray pipe cooperates with the B elastic telescopic rod to achieve the effect of moving up and down and jetting at multiple angles, so that the medicine deposited at the bottom of the chassis is sprayed by the water spray pipe to float up, and then enters the mixing rod for stirring, thereby improving the mixing efficiency of the medicine and sewage.
