Described step S1 comprises again step 101 to step 105, altogether five steps:
Step 101: collect oil drum 4, the high 1m ~ 2m of bucket, circular bung 1 diameter in upper and lower two ends is 1m ~ 1.5m;
Step 102: collected oil drum 4 upper rounded bungs 1 are cut down;
Step 103: cut two circular bore on circular bung 1, bore diameter is consistent with cement bin blast pipe 7 diameters;
Step 104: weld respectively the hollow iron conduit of a certain length in two borings, one of them is air induction conduit 2, and length is 1m ~ 1.5m, and its diameter is consistent with cement bin blast pipe 7 diameters, and its top exceeds circular bung 0.05m ~ 0.2m; Another one is outtake tube 3, length is 0.1m ~ 0.3m, its diameter is consistent with cement bin blast pipe 7 diameters, its upper end exceeds circular bung 0.05m ~ 0.2m, lower end is apart from water surface 0.1m ~ 0.3m, be suspended from water surface top in oil drum, to discharge the air being filtered after cement granules, balance bucket internal gas pressure;
Step 105: air inlet pipe 2 one end are connected with 7 colligations of cement bin blast pipe, even several circles of cutting aperture 5 of giving vent to anger on the conduit apart from the 0.7m of air induction conduit lower end, hole diameter is preferably 5mm;
Described step S2 comprises again step 201 to step 203, totally three steps:
Step 201: near being symmetrically welded 6, two reinforcing bar keeping parallelisms of two reinforcing bars below slot place, be used for supporting circular bung weight in the oil drum 4 after incising circular bung 1;
Step 202: the water of the interior injection certain volume of oil drum 4 is 75% ~ 90% of oil drum volume;
Step 203: the described circular bung 1 that has welded air induction conduit 2 and outtake tube 3 is covered above oil drum 4, rely on two parallel reinforcing bars 6 of lower end to be supported on oil drum 4 tops, cement airborne dust air induction conduit 2 inserted in the water in oil drum 4, so that can fully filter in water.
Advantage of the present invention is: the cement bin airborne dust filter of preparation not only can effectively increase effective contact area of cement airborne dust particle and water body, fully filter out the cement granules in airborne dust, reducing dust from construction sites pollutes, the mixture of the cement granules filtering out and water body can be cleared up in time simultaneously, avoid sewage sinuous flow, simply, effectively guarantee environmental sanitation when cement bin injects cement; Make full use of the waste and old oil drum and the waste steel bar that in engineering construction, produce, turn waste into wealth, manufacturing process is simple, effective, and is easy to the sewage after cleaning is filtered.
This invention can simply, effectively improve rate of penetration and hole quality, has very high hole quality through field demonstration.
