Recovering system for concrete cement mortar

Abstract

The invention discloses a recovering system for concrete cement mortar. The recovering system comprises a service rack and a sand and stone separating machine, wherein a mortar water outlet of the sand and stone separating machine is communicated with a mixing tank; a sewage pipeline extending to the upper side of a metering hopper is connected to a sewage pump water outlet arranged in the mixing tank; a setting pond is arranged on one side of the mixing tank; the mixing tank is communicated with the setting pond through an overflowing pipeline; a clean water reservoir is arranged beside the mixing tank; a water outlet pipe of a clean water pump B1 arranged in the clean water reservoir is communicated with a sewage pipe through a one-way valve FG; a one-way valve FW is arranged on the sewage pipe on a front section at the intersection joint of the water outlet pipe of the clean water pump B1; a water outlet pipe of a clean water pump B2 arranged in the clean water reservoir extends to the service rack; and a water pouring pipe is arranged between the setting pond and the clean water reservoir. The recovering system disclosed by the invention has the advantages that the structure is simple and reasonable; and the clean water pump and the sewage pump are adopted for simultaneously supplying materials, so that the wear to the pump body is reduced, the service life of the pump body is prolonged, the recovering effect of mortar water generated by washing a vehicle is remarkably improved and the maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to auxiliary equipment for concrete production, in particular to a concrete cement slurry recycling system. Background technique [0002] Concrete is the most important material in civil construction engineering. With the increasing construction scale, the reinforced concrete structure has become the main body of the building structure, which has led to the rapid development of the production of commercial concrete. According to statistics, by 1999, a total of 683 batching plants had been built nationwide, with a designed annual production capacity of 127 million cubic meters and an actual output of more than 154 million cubic meters. With such a large amount of concrete production, the problem of mud water treatment after concrete equipment cleaning has become an important problem for concrete mixing plants: on the one hand, washing equipment requires a lot of water, and on the other hand, it is the treatment of mud water after ...

Problems solved by technology

Since the recovery system is a circulation loop, the pump body circulates the material continuously during the production process, not only the production energy consumption is high, the operation is unstable, but also due to the continuous production of the pump body, a small amount of fine sand contained in the cement slurry Serious wear and tear has occurred on the pump outlet, the damage rate of the pump has increased, and the maintenance cost of the manufacturer has increased correspondingly, so many manufacturers have discarded it after using it for a period of time, and the equipped slurry recovery equipment has become a decoration
