at this time, the flocculant blanking hole 921 on the flocculant plugging ring 920 is not communicated with the flocculant middle through hole 931 on the flocculant poking ring 930, so that the flocculant in the flocculant storage cylinder 910 cannot reach the flocculation liquid preparation tank 300 through the flocculant blanking pipe 940;
the material-shifting ring driving part 950 drives the flocculant material-shifting ring 930 to rotate, so that the flocculant material-shifting ring 930 rotates at a constant speed, and then the intermediate flocculant passing hole 931 intermittently communicates with the flocculant blanking hole 921, so that the flocculant in the flocculant storage cylinder 910 can pass through the intermediate flocculant passing hole 931 and the flocculant blanking hole 921 to reach the flocculation liquid preparation tank 300 through the flocculant blanking pipe 940;
in addition, as the surface of the flocculant stirring ring 930 is provided with the flocculant stirring block 932, the rotating flocculant stirring block 932 can stir the flocculant in the flocculant storage cylinder 910, so that the flocculant can be loosened, and the blanking can be better carried out;
the flocculant stirring ring 930 is rotated at a constant speed, and the flocculant is quantitatively dosed through the cooperation of the flocculant intermediate through hole 931 and the flocculant stirring block 932, and the flocculant in the flocculant storage cylinder 910 does not block the through hole.
The invention also discloses an automatic sewage treatment method applied to the circuit board production industry, which is realized by the automatic sewage treatment equipment applied to the circuit board production industry and comprises the following steps:
carrying out precipitation treatment on the sewage through a sewage precipitation tank 200;
discharging the sewage in the sewage sedimentation tank 200 into the sewage flocculation tank 100 through the sewage delivery pipe 600;
pouring clear water into the tank body of the flocculating solution preparation tank 300;
conveying the flocculating agent in the flocculating agent storage box 820 to the tank body of the flocculating liquid preparation tank 300 through a flocculating agent conveying belt 810;
clear water and a flocculating agent in the tank body of the flocculating liquid preparation tank 300 are stirred by a flocculating liquid stirring device 700 to obtain a flocculating liquid;
the flocculating solution in the tank body of the flocculating solution preparation tank 300 is extracted by a flocculating solution extraction pump 520, and the flocculating solution is sprayed into the sewage of the sewage flocculation tank 100 by a flocculating solution spraying pipe 510;
the sewage and the flocculating solution in the sewage flocculating tank 100 are stirred and heated by the stirring and heating cage 410.
According to the automatic sewage treatment equipment 10 applied to the circuit board production industry, the sewage flocculation tank 100, the sewage sedimentation tank 200 communicated with the sewage flocculation tank 100 and the flocculation liquid preparation tank 300 communicated with the sewage flocculation tank 100 are arranged, the structure is optimized, the sewage in the sewage treatment tank is heated to a proper temperature, so that the flocculant powder is better dissolved in the sewage, and the opportunity that an operator directly contacts the flocculant powder and the sewage is reduced.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
