Description

Waste concrete recovering system

The present invention relates to a kind of waste concrete recovering system.

In the life that today, environmental consciousness promoted, ready-mixed concrete producer is surging by environmental pollution, sandstone price always, waste material is toppled over difficult treatment and artificial high price etc., and problems perplex; Generally speaking, the largest source of ready-mixed concrete waste material is the washing bay of premixing car, because all can retain many do not use or in the premixing tube of premixing car attached to the concrete of barrel, but before loading concrete next time, but will will clean up in the premixing tube, not only will remove attached to the concrete of barrel, the concrete that does not use all will abandon, so general ready-mixed concrete producer is toppled over the processing except wanting worried waste material, more can't reclaim the concrete that does not use; If have 20 premixing cars with each ready-mixed concrete factory, and the big appointment when each cleaning of each premixing car is poured out 50 kilograms concrete waste material (comprising: water for cleaning, sandstone, cement) and is calculated, a ready-mixed concrete factory will handle 30000 kilograms concrete waste material (comprising: water for cleaning, sandstone, cement) every month, not only toppling over the soil difficulty looks for, and wasting many resources virtually, can to utilize the waste concrete recovering system of concrete plant's inner concrete waste material fully be problem anxious to be solved always so develop a cover.

The waste concrete recovering system of commonly using, see also shown in Figure 1, its flow process is: vehicle is after washing bay 10 is cleaned, all concrete waste materials (comprising: water for cleaning, sandstone, cement) can flow into earlier in total material bakie 11, after process is always expected the guiding of clear water in the bakie 11, waste material can flow into total material accumulator tank 12, and within total material accumulator tank 12, do the work that separates sandstone and sewage, used first kind power this moment, subsequently, sewage is entered within the mix stillpot 14 by rhone 13, sandstone is then after the sand through the stone vibratory sieve 15 of second kind of power and the third power reclaims machine 16, can be transported to accumulation place by each self-separation, finish the recovery of sandstone; And at the sewage within the mix stillpot 14 except can be directly behind mix, supplying with the mixing machine 17, still can provide washing bay 10 to clean the water source of vehicles again via behind the

mix stillpot

18,19; Though the above-described waste concrete recovering system of commonly using is very effective in practicality, under permanent the use, many improved shortcomings for the treatment of appear also:
