Description

A kind of preparation method of cement bin airborne dust filter

Technical field

The present invention relates to construction engineering technical field, specifically a kind of preparation method of cement bin airborne dust filter.

Background technology:

Cement bin injects bulk cement process, and in order to bulk cement particle is squeezed into warehouse smoothly, balance bunker internal gas pressure, installs blast pipe usually on warehouse, makes gas in storehouse when pouring into cement, can ensure cement bin inside and outside air pressure balance.Larger owing to pouring into pressure, when pouring into cement granules, by in the gas that bloats outside cement bin containing a large amount of cement granules, the mixture of the two composition is discharged into outside storehouse with airborne dust form, cause serious dust pollution, usually blast pipe is accessed in a puddle to filter the cement granules in airborne dust in construction site, though this kind of method has certain filter effect, but blast pipe is easy to goes out the water surface because air pressure is excessive, a large amount of cement airborne dust is caused to enter in air, and the sewage in puddle is also easily because comparatively atmospheric pressure flows to outside place, causes environmental pollution.

Summary of the invention:

The invention provides a kind of preparation method of cement bin airborne dust filter, the cement bin airborne dust filter of preparation, effective contact area of cement airborne dust particle and water body effectively can not only be increased when injecting cement to cement bin, fully filter out the cement granules in airborne dust, reduce dust from construction sites to pollute, the mixture of the cement granules filtered out and water body can be cleared up in time simultaneously, avoid sewage sinuous flow, simply, effectively ensure environmental sanitation during cement bin injection cement.Turn waste into wealth simultaneously, effectively make use of engineering waste product, improve the environmental sanitary quality of job site.

The preparation method of a kind of cement bin airborne dust of the present invention filter, includes step S1 and step S2, totally two steps.

Described step S1 is incising circular bung 1 and makes air induction conduit 2, the outtake tube 3 of certain specification thereon;

Described step S2 on oil drum 4 welded reinforcement support to support circular bung 1 weight.

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 bung 1 is cut down;

Step 103: cut two circular bore on circular bung 1, bore diameter is consistent with cement bin blast pipe 7 diameter;

Step 104: the hollow iron conduit welding a certain length in two borings respectively, 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 diameter, and its top exceeds circular bung 0.05m ~ 0.2m; Another one is outtake tube 3, and length is 0.1m ~ 0.3m, and its diameter is consistent with cement bin blast pipe 7 diameter.Its upper end exceeds circular bung 0.05m ~ 0.2m, and lower end distance water surface 0.1m ~ 0.3m, is suspended from oil drum above the water surface, to discharge the air after being filtered cement granules, and balance bucket internal gas pressure;

Step 105: air inlet pipe 2 one end is connected with cement bin blast pipe 7 colligation, at aperture 5 of giving vent to anger apart from several circles of cutting even on the conduit within 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: be symmetrically welded two reinforcing bars, 6, two reinforcing bar keeping parallelisms near the below at slot place in the oil drum 4 after incising circular bung 1, be used for supporting circular bung weight;

Step 202: the water injecting certain volume in oil drum 4 is 75% ~ 90% of oil drum volume;

Step 203: the described circular bung 1 having welded air induction conduit 2 and outtake tube 3 is covered above oil drum 4, two parallel rebar 6 of lower end are relied on to be supported on oil drum 4 top, air induction conduit 2 is inserted in the water in oil drum 4, fully can filter in water to make cement airborne dust.

Advantage of the present invention is: the cement bin airborne dust filter of preparation effectively can not only increase effective contact area of cement airborne dust particle and water body, fully filter out the cement granules in airborne dust, reduce dust from construction sites to pollute, the mixture of the cement granules filtered out and water body can be cleared up in time simultaneously, avoid sewage sinuous flow, simply, effectively ensure environmental sanitation during cement bin injection cement; Make full use of the waste and old oil drum and waste steel bar that produce in engineering construction, turn waste into wealth, manufacturing process is simple, effective, and is easy to clear up the sewage after filtering.

This invention simply, effectively can improve rate of penetration and hole quality, has very high hole quality through field demonstration.
