The specific working principle of the invention is as follows:

when the sewage ecological purification treatment device is used, the rough essence treatment process of the device needs to be known firstly, sewage enters the filter box 2 through the drain pipe 6 connected with the sewage box 1, impurity particles are filtered through the filter structure in the filter box 2 and then flow into the transfer box 8, and then the chemical agent and the sewage are mixed through the mixing frame 7 structure at the rear side of the transfer box 8, so that all elements in the sewage completely and fully react with the chemical agent, and finally, the purified water flows into the circulation box 3 and can be pumped into the sewage box 1 again through the pump body 4 for circular purification;

sewage flows into the top of the filter tank 2 through a drain pipe 6 between the sewage tank 1 and the top of the filter tank 2, water flow impacts a plurality of filter frames 203 on the periphery of the fixed column 201, so that the filter frames 203 rotate on the periphery of the fixed column 201 through the rotary drum, the water flow entering the filter tank 2 is filtered through a second filter screen 206, the filtered impurities float on the surface of the second filter screen 206, meanwhile, the cleaning brushes 205 at the bottoms of the plurality of filter frames 203 driven to rotate by the impact of the water flow clean the impurities on the surface of the second filter screen 206, and the first filter screen 204 on the filter frames 203 can also play a certain role in intercepting the impurities;

when the filter frame 203 on the periphery of the drum is impacted to pass through the lower limiting rack 202, the limiting rack 202 and the gear 207 fixed at the inner end of the filter frame 203 are engaged, so that the filter frame 203 is turned over when passing through the section (due to the arrangement of the collecting box 208, the space of the collecting box 208 is larger than that of the filter frame 203, so that the filter frame can be ensured to be turned over for one circle, a certain turning space is provided for the filter frame 203, specifically, the combination of the figure 2 and the schematic diagram of figure 3 shows that the cleaned impurity particles are swept into the lower collecting box 208, the internally intercepted impurity particles are poured out at the same time, after the filter frame 203 completely passes through the limiting rack 202, the turning space for one circle is realized, the initial position is restored, the cleaning of the filter screen II 206 and the intercepting and pouring work of the impurities are driven to be circularly carried out along with the impact of water flow, and the filtered impurities are all collected in the collecting box 208;

in the working process, the impact force of sewage is utilized, the garbage on the filter screen is cleaned and collected, the trouble of manual cleaning in the traditional mode is replaced, the integral working efficiency is effectively improved, and the device is more energy-saving and efficient;

the collecting box 208 can be taken out from the filter box 2, the impurities collected inside can be cleaned and poured out periodically, and the collecting box 208 is reloaded into the filter box 2 through the corresponding sliding grooves which are formed along the inside of the filter box 2 by the convex edges 209;

sewage passing through a second filter screen 206 and a third filter screen 210 in a filter box 2 enters the filter box 2, at the moment, a control valve 13 on a chemical tube 11 is controlled to be opened, the flow passing size of the control valve 13 can be adjusted, chemical agents in a chemical cavity 212 in the filter box 2 are introduced into a mixing tube 9 through the chemical tube 11, the sewage flowing into the filter box 2 enters a second guide tube 215 through a first guide tube 211, and finally is introduced into a transfer box 8 through a second communicating tube 16, the sewage introduced into the transfer box 8 impacts fan blades 15 inside the transfer box, so that the whole mixing frame 7 structure connected with a sealing cover rotates, the sewage flowing into the transfer box 8 flows into a plurality of purifying tubes 10 introduced into the transfer box 8, as the purifying tubes 10 rotate along with the mixing frame 7, water accumulated at the bottom of the transfer box 8 can enter the purifying tubes 10 one by one, as communicating tubes 14 are connected between the plurality of purifying tubes 10 and the middle mixing tube 9, the sewage in the purifying tubes 10 can be fully mixed with the chemical agents in the mixing tube 9, and can enter a sewage circulating tank 3 after being mixed and reacted, and can be treated again through a sewage circulating tank 3;

as the liquid level of the medicament in the medicament cavity 212 is lower, the floating plate 213 connected with the lower end of the first guide pipe 211 at the upper end of the first guide pipe 211 moves downwards along with the descending of the liquid level, as the upper end of the first guide pipe 211 moves downwards to a certain distance, the inlet at the side surface of the first guide pipe 211 is closed, water flow does not flow into the first guide pipe 211 and flows into the water outlet pipe 12 connected with the lower end of the first guide pipe through the through groove 214, the liquid level of the medicament drops to the bottom, which indicates that chemical medicament required for treating the batch of sewage is completely and fully mixed and reacted with the sewage, therefore, the sewage purification treatment process is finished, and purified water after treatment is obtained along with the outflow of the water outlet pipe 12;

simultaneously the size of this device accessible regulating and controlling valve 13's flow, control the speed that the inside chemical agent liquid level of medicament chamber 212 descends, along with the slowing down of the falling speed of the inside liquid level of medicament chamber 212, the time that sewage passes through pipe 211 and pipe two 215 is just longer, this time sewage treatment cycle's number of times is just more just also more, consequently the staff is with relying on the working experience, according to the pollution degree of sewage reality, the reasonable circulation number of times of this device sewage treatment of adjustment of accessible regulating and controlling valve 13, and then reach high-efficient and high-quality sewage purification treatment work.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
