Abstract
The invention provides an unbaked aeration pipe for filtration in wastewater treatment. The unbaked aeration pipe has short production cycle; the price of common quartz sand as a material of the aeration pipe is one-tenth of the price of corundum sharper sand; and the aeration effect generated by the aeration pipe is doubled than that of the prior ceramic baked aeration pipe. The unbaked aeration pipe is suitable for manufacturing the aeration pipe of various domestic wastewater treatment plants at present and is a revolutionary product for filtration and aeration of wastewater treatment.
Description
Technical field:
The invention belongs to the sewage disposal goods, specially refer to a kind of preparation method of non-calcination aeration pipe for effluent treatment and filtering.
Background technology:
The calcination aeration pipe that present wastewater treatment in China factory has adopted the ceramic mode of a large amount of usefulness to make; use as present Tianjin Dong Li sewage treatment plant; be the supporting aeration tube of import equipment; 60 centimetres of this aeration head lengths; 10 centimetres of circular diameters; 20 centimetres of wall thickness; be to burn till through high temperature 1260 degree with No. 36～No. 60 common diamond spar particles vitrified bond that is mixed; burn till this aeration tube and need the dress attitude of gross blow hole; could produce good aeration performance; the use length of this elongated tubular aeration tube is about 1.2 meters; and suppress with the method for high-temperature roasting; can only make 60 centimeter length; splice use then; because in the vitrified abrasive tunnel cave of 1260 degree, burn till this aeration tube; percent defective is quite high; as long as especially the tubulose aeration tube has 3～5 millimeters modification; just can not use; domestic many grinding tool goods unit all has no way out to this product; especially this aeration tube will have a large amount of micropore to produce enough aeration rates, and finish by bulky grain as long as add in the batch mixing process by product for this micropore, and the crack of porous more that this carbon granules is put is many more; aeration is just good more, but the modification in the production roasting also is big more.The present invention adopts the mode of no roasting to produce this aeration tube, adopt insatiable hunger to close mylar as bond, common quartz sand is as the aeration tube main material, micropore all divides to be finished by 36 orders～80 purpose sea salt particles, in whole pressing process, adopt the mode of dry blend, hand is removed forcing press compression moulding, aeration tube is by metal die compression moulding, solidified in 30 minutes, aeration tube after the demoulding can be put into warm water and soak 8 hours, make granulated salt in the aeration tube in water, soak in dissolving, the aeration tube nature expose needed a large amount of micropores in the design.Because be 30～50 degree drying formings, need not product is put into the hyperthermia tunnel Kiln roasting, saved a large amount of roasting costs like this, and the aeration tube of producing can whole length one-shot forming need not bonding.A kind of non-calcination aeration pipe for effluent treatment and filtering that the present invention produces, with short production cycle, the common quartz sand of its material is 1/10th of diamond spar grinding tool sand price, the aeration effect that it produces doubles than former ceramic calcination aeration pipe.Being suitable at present the aeration tube of domestic various sewage treatment plants and making, is a kind of revolutionary product to the filtration and the aeration of sewage disposal.
Technology contents:
The present invention adopts insatiable hunger to close No. 306 bonds as aeration tube of mylar, tube wall adopts 16～No. 100 quartz sands, the pore-creating material adopts 16～60 order edible salts, mould adopts steel die, the center of steel die is made up of split combination plug, in order that after compression moulding, from aeration tube, freely extract, mold shell is two semicircles, the interface bolted connects, can freely open after the formed product, expose the whole tube wall of aeration tube, can be mixed with yellow according to the color needs of product, grey, shades of colours such as redness, color adopts polyester look refining work, adds when being mixed material.
Specific embodiments:
1. at first prepare the dry blend of 1000 grams, it is as follows to fill a prescription:
No. 306 250 grams of mylar curing agent 10 grams are closed in insatiable hunger
White quartz sand 46 orders 200 restrain, 16 orders 150 restrain,
60 orders, 200 grams, 100 orders, 100 grams
Promoter 10 gram edible salts 46 orders～60 orders, 100 grams
Colored polyester mill base 30 grams
2. take the mode of cover half moulding with the particular manufacturing craft of existing making aeration tube, above material is mixed evenly pours mould into, with the compression moulding of 100 tons of four-column type plastic hydraulic press, the plug of mould adopts split type, can freely extract in order to after the aeration tube compression moulding.
3. all micropore parts of a non-calcination aeration pipe for effluent treatment and filtering, be to finish by the edible salt particle in the prescription, pore-creating material carbon granule in the aeration tube of this and high-temperature roasting is different, high-temperature roasting is by high-temperature carbon granules to be burnouted, and the present invention is after solidifying by moulding, expose uniform micropore after being dispersed in the salt particle immersion in the product, the product after compacting is solidified is put into 40 degree warm water and was soaked 8 hours, makes the salt particle all be melted into water.
4. the intensity of product of the present invention, hardness and impact resistance are the same with the high-temperature roasting product, the product of high-temperature roasting mostly is a grey, a kind of non-calcination aeration pipe for effluent treatment and filtering of the present invention can be versicolor, finishes because color can be made various polyester mill bases in prescription.
