CN201720054425.X discloses a concrete slurry recovery device, including carwash groove and sand-stone separator who is linked together with it, sand-stone separator corresponds respectively and is connected with building stones district and sand material district, and the carwash inslot is provided with stone silo and the sieve that is used for separating coarse stone and fine stone, and the coarse stone rolls to the building stones inslot through the sieve surface, and stone silo and building stones district are linked together, are formed with the inner chamber between sieve and the carwash inslot wall, and the inner chamber is linked together with sand-stone separator. Mud water after carwash emptys on the sieve of carwash inslot, the boulder rolls to the stone silo of carwash inslot through the sieve surface, directly lead to the building stones district through the building stones groove, fine stone, fine sand and water wear to establish the sieve and enter into to flow to sand and stone separator behind the inner chamber, utilize the carwash groove at first to sieve the boulder of mud aquatic, and then reduce the volume of large granular materials in whole mud aquatic, be favorable to reducing sand and stone separator's load and the actual use power of its motor, extension equipment life.

These are two types of devices used in the art for collecting waste car wash liquid in tank cars.

However, the two schemes only explain the storage and separation of the cleaning waste liquid in the tank, and the conventional treatment measures are that the cleaning waste liquid is discharged after reaching the discharge standard through multi-stage precipitation.

This company provides a new solution, namely, get the thick liquid after the grit separation to the washing waste liquid in the jar, retrieve the thick liquid through two kinds of ways, the first way is with thick liquid reuse go wash jar inside, another kind of way is with thick liquid retrieval and utilization to production system, should say that these two kinds of ways are all lacked one by one, because if with the continuous repeated washing jar inside of going on of thick liquid, the thick liquid can not avoid facing the problem of ageing, concentration increase, only timely with the thick liquid part drainage to production system can guarantee the continuous balance of whole solution.

When the slurry is applied to the production system, it is generally intermittent, i.e., when the slurry in the waste liquid tank is sufficient and the production system needs water, the slurry is recycled to the production system.

Because of the intermittent slurry transport, there is a problem that cement in the slurry adheres to the pipe wall, which has long been known to cause pipe clogging.
