[0030] In this embodiment, the device screens the solid impurities in the sewage by arranging a screening end inside the tank body 11 and guides them into the debris collection shell 212 for centralized collection. Among them, a shielding part 213 is arranged between the tank body 11 and the debris collection shell 212 to shield the communication port between them to prevent sewage from entering the debris collection shell 212. Secondly, a mixing shell 221 is arranged inside the tank body 11, and a stirring part 222 is arranged in the mixing shell 221 to drive the sewage and the neutralizing agent to react to achieve the effect of neutralizing the sewage.

After being purified by the purification mesh plate 234 inside the purification tank 233, it is discharged outwards through the discharge port 235, which facilitates the staff to recycle the purified sewage.

[0037] To better understand the present invention, the following is combined with Figures 1 to 4A detailed description of the technical solution of the present utility model is as follows: The staff pours sewage into the box body 11 from the feed port 12. At this time, the air cylinder 2131 does not drive the baffle plate 2132 to move. The baffle plate 2132 is used to block the communication port between the box body 11 and the impurity collection shell 212. After the sewage is screened by three screen meshes 211, it flows into the mixing shell 221. When no more sewage is introduced, the air cylinder 2131 is started. The air cylinder 2131 drives the baffle plate 2132 to move and makes its through hole 21321 communicate with the communication port. The solid impurities screened out fall into the impurity collection shell 212. The staff introduces the neutralizing agent into the mixing shell 221 through the dosing port and starts the motor 2221. The motor 2221 drives the shaft body 2222 to rotate. The shaft body 2222 drives a plurality of stirring blades 2223 to carry out a neutralization reaction on the sewage and the neutralizing agent in the mixing shell 221. During the neutralization reaction, the inner wall of the mixing shell 221 can be cleaned by the scraping blade 2224. At the same time, a groove body 22231 is arranged on the stirring blade 2223, and a magnet bar 22232 is arranged in the groove body 22231. The metal impurities in the sewage can be adsorbed by the magnet bar 22232. When the subsequent neutralization is completed, the pump body 232 is started.
