Specifically, the mixing chamber 11 is used to hold the treatment agent, and can be pre-mixed and enter the box body 10 through the liquid outlet 112. The wastewater enters the mixing chamber 101 of the box body 10 through the water inlet pipe 12 and mixes with the treatment agent to achieve acid-base neutralization reaction of the wastewater and purify the wastewater.

[0044] Attached to the instruction manual Figure 1 It can be seen that the first stirring paddle 14 has a first stirring shaft 141 and a plurality of blades arranged thereon, which are arranged in the stirring chamber 11 and rotated under the drive of the driving mechanism 20 for stirring the treatment agent; the second stirring paddle 15 has a second stirring shaft 151 and a plurality of blades arranged thereon, which are arranged in the mixing chamber 101 and rotated in the opposite direction to the first stirring paddle 14 under the drive of the driving mechanism 20; the first filter plate 17 is obliquely arranged in the filter chamber 102 below the outlet of the conduit 16 for performing a first filtration on the treated wastewater, and impurities in the wastewater can be intercepted on the first filter plate 17; the second filter plate 18 is arranged in the filter chamber 102 below the first filter plate 17, and reciprocates and vibrates under the drive of the vibration assembly 50 for secondary filtration of the wastewater, so that impurities such as suspended matter in the wastewater are separated more thoroughly. Specifically, the filter holes of the second filter plate 18 are smaller than the filter holes of the first filter plate 17, so as to facilitate a more sufficient filtering operation and improve the treatment effect of the wastewater.

[0045] As an embodiment, according to the attached Figure 4-5 It can be seen that the driving mechanism 20 includes: a first bevel gear 21, a driving shaft 22, a second bevel gear 23, a first motor 24 and a connecting assembly 30, wherein the first bevel gear 21 is connected to the end of the second stirring shaft 151 that passes through the box body 10; the driving shaft 22 is rotatably arranged on the outer wall of the box body 10, and is sleeved on the second stirring shaft 151; the second bevel gear 23 is arranged at the end of the driving shaft 22, and is arranged opposite to the first bevel gear 21; the third bevel gear 25 arranged at the power output end of the first motor 24 is located between the first bevel gear 21 and the second bevel gear 23, and the two are respectively meshed; the connecting assembly 30 is respectively connected to the driving shaft 22 and the first stirring paddle 14, and is used to drive the first stirring paddle 14 to rotate.

[0046] When in use, the first motor 24 drives the third bevel gear 25 to rotate, which can simultaneously drive the first bevel gear 21 and the second bevel gear 23 to rotate, and the two have opposite directions, so that the second stirring shaft 151 can turn in the opposite direction to the driving shaft 22, and then under the drive of the connecting component 30, the first stirring paddle 14 and the second stirring paddle 15 turn in the opposite direction, which is conducive to more fully mixing the wastewater and the treatment agent, improving the reaction effect, and having strong practicality.

By using the nozzle 70 to spray water to the first filter plate 17 for cleaning, it is conducive to timely treatment and improves the filtering effect. When the work is completed, the box 10 can be opened to collect the impurities washed to the corners in a unified manner, which is convenient to operate.

[0052] As an embodiment, according to the attached Figure 4 It can be seen that there are two conduits 16, and the conduits 16 are distributed on both sides of the hydraulic cylinder 41 so as not to interfere with each other. In addition, in actual production, the number of conduits 16 can be set as needed to improve the transmission efficiency of wastewater.
