Embodiment Construction

[0037] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] refer to Figure 1 to Figure 9 , the present embodiment provides a method for preparing aluminum sludge ceramsite, the steps are as follows:

[0039] In the first step, the moisture content of aluminum sludge extrusion dehydration is controlled at 20% to 30%;

[0040] In the second step, the aluminum sludge obtained after the treatment in the first step and the electroplating sludge, iron oxide, and fly ash are weighed by measuring instruments, and matched according to the following mass percentages: 10% to 20% of electroplating sludge, aluminum Sludge 20-40%, iron oxide 0-7%, fly ash 40-50%;

[0041] In the third step, the above-mentioned materials are first added to the mixer for stirring, and water with a mass fraction of 0-5% is added for stirring;

[0042] The fourth step is to transport the mixed material evenly stirred in the third ste...

Abstract

The invention relates to the technical field of sludge waste utilization, in particular to a method for preparing aluminum sludge ceramsite. , and then transported to the dryer, and then transported the ceramsite raw meal to the rotary kiln for roasting. After being classified and screened by the closed screening machine, the waste and the ceramsite smaller than the standard size were transported to the crushing device through the closed conveyor. , use the crushing device to crush and sieve and then transport it to the storage tank of the mixed raw materials, and then weigh and mix the mixed raw materials with the measuring instrument, and recycle the waste materials. The produced ceramsite can be used in roadbed materials, concrete aggregates, etc. It is widely used; the mixed materials are formed into agglomerates. After the sludge is processed, the ceramsite fragments are crushed, transported and recycled by the crushing device. Through further processing, the recycling rate of waste can be enhanced and the production efficiency can be further improved.

Description

technical field [0001] The invention relates to the technical field of sludge waste utilization, in particular to a method for preparing aluminum sludge ceramsite. Background technique [0002] At present, the Chinese patent number: CN201810663263.9 discloses a method for preparing aluminum sludge ceramsite, which includes mixing and granulating aluminum sludge, egg shells, fly ash, and glass powder to obtain raw ceramsite, then drying, preheating, Sintering, cooling, that is. In parts by mass, the proportions of the aluminum sludge, egg shells, fly ash and glass powder are 50-80%, 5-20%, 10-20%, 5-15%. The glass powder comes from waste from waste glass processing plants, and is quartz glass powder with a SiO2 content of 99%; the fly ash comes from waste from thermal power plants or heating companies; the egg shells are from the canteen of Xi'an University of Science and Technology. Solve the problem that the main raw material of clay ceramsite is mainly taken from the hig...
