in more detail:

1. the working principle is as follows: firstly, the waste water that the waste water needs to be handled is sent into main cell body through waste water mixture conveyer pipe, and in this process, the waste water mixture will be through reciprocal screening plant at first, promptly: the waste water in the waste water mixture enters the main tank body through the sieve holes on the first screening net and the second screening net, and the granular mixture is left on the first screening net and the second screening net, so that the screening work is finished; secondly, as the first screening net and the second screening net which form the screening module are connected with the waste water breast board and the transmission chain through the supporting rods, when the transmission chain starts to move through a gear (driven by the existing motor), the screening module can be driven to move along with the 'moving state' of the transmission chain, and as the moving state of the transmission chain is similar to that of a 'conveying belt' (or a conveying belt), part of granular mixtures (such as sand and stones) on the screening module can roll towards two sides of the screening module (namely, one side of each second screening net far away from the first screening net), and part of the sand and stones can be conveyed into silt recovery pools at two sides of the main pool body to complete the primary separation of waste water and the granular mixtures; finally, the waste liquid in the main tank can be respectively sent into a waste liquid recovery tank (namely, the waste liquid in the main tank is controlled to enter into which waste liquid recovery tank by a manual control valve), and in the process, the waste liquid in the main tank is further separated by a secondary screening device, so that the entering of granular mixtures into the waste liquid recovery tank is reduced, namely: controlling the waste liquid to enter one of the waste liquid recovery tanks through a valve, and controlling the waste liquid to enter the other waste liquid recovery tank through the valve when the waste liquid in the waste liquid recovery tank reaches a certain amount, so that the waste liquid in the previous waste liquid recovery tank is precipitated, and then the waste liquid in the previous waste liquid recovery tank is extracted; it should be noted that: when the sand and stone in the main tank body, the silt recovery tank and even the waste liquid recovery tank reach a certain amount, the sand and stone can be periodically cleaned;

2. the working principle of the secondary screening device is as follows: the waste liquid in the main tank body enters the screening box body through the first industry shooting pipe, firstly falls on the supporting plate and flows through the third screening net along the supporting plate, the waste liquid enters the liquid discharge cavity through the third screening net and is discharged into the waste liquid recovery tank through the second liquid discharge pipe, when the granular mixture (namely, the granular mixture stacked on the supporting plate) in the screening cavity reaches a certain amount, the supporting plate is pulled down through the air cylinder (namely, the supporting plate is overturned by taking the hinged shaft as a base point, so that the granular mixture on the supporting plate falls on the bottom of the screening cavity), and the part of the granular mixture (such as sand and stone) is cleaned through the sewage discharge port, and when the waste liquid is screened, the supporting plate is reset through the air cylinder;

3. it should be noted that:

first, the special design of the first screening net and the purpose of the second screening net being in an inclined state are: when the waste water mixture falls on the first screening net, the waste water can pass through the first screening net, and simultaneously, the granular mixture screened and left on the first screening net can roll towards the second screening net and further roll (or move) towards one side of the second screening net far away from the first screening net, and fall into a silt recovery tank;

secondly, after the rotating shaft arranged on the wastewater baffle plate is driven by a motor, the rotating shaft is fixedly connected with a silt scraper to partially feed the granular mixture on the second screening net into each silt recovery tank, so that a large amount of granular mixture (such as sand and stone) is prevented from being accumulated on the second screening net, and the silt scraping shaft and the shaft diameter thereof can improve the effect of scraping silt;

in conclusion, this embodiment has the precipitation efficiency and the effect that can guarantee waste water, promptly: "precipitation effect" and "precipitation efficiency" in the waste liquid recovery pond (get into the waste liquid recovery pond and improve the screening effect to waste water through reducing silt), secondly, reduce the probability that silt was taken out from the waste liquid recovery pond to next one-stage process step, avoid influencing the treatment effect of next process step to waste water.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
