Description
Technical field
The utility model relates to sodium silicate sand casting field, is specifically related to a kind of sodium silicate sand wet reclamation Sewage treatment systems.
Background technology
The wet reclamation of Ester cured used sodium silicate sand is subject to the welcome of casting industry with its high demoulding rate and high-recovery, but the sewage that this method produces also becomes a difficult problem simultaneously, used sodium silicate sand wet reclamation can produce the sewage that a large amount of basicity is high, suspended substance is many, this sewage is due to the existence of silicic acid sol, be difficult to natural sedimentation, under the condition without clarification, if it is used as recirculated water, the life-span of pump and the quality of reclaimed sand will be had influence on, if its discharge water drain, do not meet the emission standard of trade effluent, and can environmental pollution be caused.
In prior art, domestic foundry does not have agent-feeding treatment mostly to used sodium silicate sand wet reclamation sewage, only adopt natural sedimentation method, effect is poor, some foundry adopts lime or carbide slag to process as coagulating agent, has certain clarifying effect, but also improves the basicity of water simultaneously, add sludge quantity, other producer remaining then adopts suite of equipment and the technique of the manufacturer production of the special sewage apparatus produced.But these suite of equipment and technique are not develop for the feature of Ester cured used sodium silicate sand wet reclamation sewage specially, and universality is poor, and input cost is high, and sewage treating efficiency is low.
Utility model content
The utility model, for the above-mentioned state of the art, proposes a kind of high treatment efficiency, lower production cost, and the mud that can produce sewage does the used sodium silicate sand wet reclamation Sewage treatment systems of effectively process.
In order to realize final purpose of the present utility model, adopt following technology:
Used sodium silicate sand wet reclamation Sewage treatment systems, comprise sewage lagoon (2), also comprise the mixing tank (7) be connected with sewage lagoon (2) by pipeline, and the apparatus for treating sewage (9) to be connected with mixing tank (7), connecting pipeline between described sewage lagoon (2) and mixing tank (7) is provided with medicine-adding bin, and described apparatus for treating sewage (9) is also connected with sludge treatment equipment.
Further, described medicine-adding bin comprises medicament barrel (4) and acid adding bucket (5).
Further, the connecting pipeline between described sewage lagoon (2) and mixing tank (7) is also provided with slush pump (6).
Further, the connecting pipeline between described mixing tank (7) and apparatus for treating sewage (9) is also provided with pH value comparator (8), is mainly used in the potential of hydrogen of monitoring the sewage after dosing, for dosing number make reference.
Further, described apparatus for treating sewage (9) bottom is provided with the straight-through pipeline connecting sewage lagoon (2).
Further, described sludge treatment equipment comprises sewage sludge storage tank (10), is arranged on Pulp pump (11) and the pressure filter (12) of sewage sludge storage tank (10) lower end.
Further, described medicament barrel (4) is flocculation agent bucket and coagulating agent bucket respectively.
Further, described mixing tank (7) be mechanical stirring mixing tank, the combination of one or more in tubular static mixer, eddy current type static mixer, diffusion mixer.
This utility structure is simple, enterprise's input cost is low, sewage treating efficiency is high, and the neutral clear water after sewage disposal fullys meet technical grade clear water standard, can be used as wet method casting clear water secondary circulation and utilizes, greatly save wet method casting running cost, meanwhile, native system processes the mud in sewage, after sludge treatment equipment process, mud can be used as footway brick and reclaims use, has saved resource.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Used sodium silicate sand wet reclamation Sewage treatment systems, comprise sewage lagoon 2, also comprise the mixing tank 7 be connected with sewage lagoon 2 by pipeline, and the apparatus for treating sewage 9 to be connected with mixing tank 7, connecting pipeline between described sewage lagoon 2 and mixing tank 7 is provided with medicine-adding bin, described apparatus for treating sewage 9 is also connected with sludge treatment equipment, and described sludge treatment equipment comprises sewage sludge storage tank 10, is arranged on Pulp pump 11 and the pressure filter 12 of sewage sludge storage tank 10 lower end.
Principle of work of the present utility model is: the sewage that wet method casting produces is under the effect of mixing pump 1, drop in sewage lagoon 2, sewage in sewage lagoon 2 is pumped in mixing tank 7 along suction line 3 under the effect of slush pump 6, suction line 3 is provided with flocculation agent bucket, coagulating agent bucket, acid adding bucket 5, after dosing, sewage enters into apparatus for treating sewage 9 after mixing tank 7 fully mixing, pipeline between mixing tank 7 and apparatus for treating sewage 9 is provided with pH value comparator 8, for monitoring the sewage potential of hydrogen after dosing, so that the dosage of dosing when determining next dosing, the sewage that apparatus for treating sewage 9 does not process cmpletely turns back in sewage lagoon 2 along the straight-through pipeline bottom it and does secondary decontamination process again, sewage completely after process is then transformed into neutral clear water and then flows into clean water basin 15, the mud that sewage produces is through hold-up vessel 10, Pulp pump 11 and pressure filter 12 form mud cake 13, can be used as footway brick secondary recovery to utilize.
