The waste liquid after pickling contains soluble solute and waste slag falling off after partial pickling, a specific pickling waste liquid slag sedimentation tank is needed to be used for precipitating insoluble solid waste slag in the pickling waste liquid, filtering and fishing out the waste liquid, and then treating the pickling waste liquid to enable the waste liquid to reach the discharge standard.
Regarding solid waste filtration, the methods currently employed are: placing the waste pickle containing the waste slag into a sedimentation tank, discharging the waste liquor after the waste slag is settled, and then fishing out the waste slag; because in the sedimentation process, the time required by the method is long, the waste residues are precipitated to the bottom of the sedimentation tank, and the labor and the time are wasted when the workers salvage the waste residues, and the waste residues precipitated at the bottom are easy to adhere to the bottom wall of the sedimentation tank, so that the cleaning is difficult.
It has the following drawbacks:
1. the time required for precipitation is long;
2. manually fishing out waste residues, which is time-consuming and labor-consuming;
3. the waste residue contacts the bottom wall of the sedimentation tank, is easy to adhere to the bottom wall for a long time, and is difficult to clean.
4. Secondly, in the filtration process of pickling waste liquid, when the workman adopts instrument such as filter screen to filter the waste liquid, because its particulate matter is sometimes great in the waste liquid, leads to particulate matter to block up the filtration pore of filter screen for the filtration pore is stopped up completely and can't permeate water, leads to its filtration performance to reduce, and needs frequent clearance, just can guarantee the continuous use of filter screen.

Because the fluid with filtration is in a slow flowing state, the density of the particles is higher than that of the fluid, the particles naturally sink, and the particles are not extruded and blocked at the filter holes along with the movement of the fluid, so that the filter screen can be effectively prevented from being blocked, but the filterable particles are limited to the particles with the density higher than that of the fluid, such as the metal and oxide thereof in the pickling waste liquid.
As shown in fig. 8, since the flow rate of the waste liquid is not controllable, the flow rate is too high, so that the particulate matters or the waste residues are blocked and blocked at the filter holes, in order to solve the blocking phenomenon, the cross section of the protrusion 7 is in an 'angle' shape, the protrusion 7 further comprises a transition surface 70, the transition surface 70 is obliquely arranged, the filter surface 71 is horizontally arranged, and the included angle between the transition surface 70 and the filter surface 71 is smaller than 90 degrees. When the high-pressure water gun is used for flushing from the back of the filter screen, high-pressure water can flow along the transition surface, and the water flow perpendicular to or inclined to the plate surface tends to be deflected, so that the high-pressure water impacts the filter surface, impacts the filter holes and flushes the plugs from the meshes.
As shown in fig. 3, the pickling waste liquid needs to be subjected to certain pretreatment to neutralize acidity or sediment toxic substances in the pickling waste liquid, and the pickling waste liquid sediment precipitation system further comprises a medicine barrel 80, a medicine injection pipe 82 and a medicine adding pump 81, wherein one end of the medicine injection pipe 82 is connected with the medicine adding pump 81, the other end of the medicine injection pipe 82 faces the top of the lower filter tank 4, and the medicine adding pump 81 is connected with the medicine injection pipe 82 and the bottom of the medicine barrel 80.
The medicine tank 80 is used for containing a medicine, and the medicine may be an alkaline substance for neutralizing the acidity of the pickling waste liquid or a substance for precipitating toxic substances dissolved in the pickling waste liquid by reacting.
The medicine barrel 80 is provided with a stirring mechanism, and comprises a blade and a motor, wherein the motor is fixed at the top of the medicine barrel, the blade is connected with the motor, and the blade is positioned in the medicine barrel. The motor is electrified to drive the paddle to rotate, so that the medicaments in the medicament barrel 80 can be stirred and mixed, the medicaments which are required to be prepared on site can be rapidly prepared on site, and the medicaments are immediately conveyed into the sedimentation tank through the medicament adding pump, so that the medicament is prevented from volatilizing or failing due to too long time.
The drug adding pump extracts the corresponding drug from the drug barrel, injects the drug into the filtered pickle liquor through the drug injection pipe, neutralizes the acidity or separates out the toxic dissolved matters and filters the pickle liquor.
The foregoing description of the preferred embodiment of the invention will so fully reveal the true scope of the invention that others skilled in the art can, by applying to it, readily modify and adapt for various usages such specific embodiments without departing from the true spirit and scope of the invention.
