Abstract
The invention discloses a method for producing construction bricks purely from sludge, which comprises the steps of sludge dehydrating, charging coal slag, proceeding homogenization treatment, ageing treatment, making wet raw bricks with vacuum brick extruder, wet raw bricks natural drying and dry bricks sintering.
Description
(1) technical field
The present invention relates to a kind of method of producing material of construction.Be the method that adopts pure sludge to produce fragment of brick for building specifically.
(2) background technology
Since ancient times, fragment of brick for building all is to make with pure clay.Though adopt the pure clay can brickmaking, satisfy architectural needs.But pure clay all is a topsoil of taking from the face of land, if use pure clay brickmaking for a long time, will destroy the arable land, cause falling into disuse in a large number of arable land.
On the other hand, for administering rivers,lakes and seas, need take out substantial contribution rivers,lakes and seas are carried out desilting.And mostly be deposited on the face of land even the arable land from the marine mud that clears in rivers lake.Because contain a large amount of objectionable impuritiess such as heavy metal in the mud, this objectionable impurities can cause secondary pollution to underground water.Therefore, mud is deposited on the face of land or the arable land, not only can causes falling into disuse of arable land, also can pollute environment.
(3) summary of the invention
The problem to be solved in the present invention provides a kind of method of utilizing pure sludge brickmaking.Adopt this method brickmaking, can reduce falling into disuse, avoiding environment is polluted of arable land.
For addressing the above problem, the present invention takes following technical scheme:
Utilize the method for pure sludge brickmaking may further comprise the steps:
(1) earlier the mud that digs out is dewatered, make its water ratio less than 30%; Simultaneously, get cinder ready, and cinder is carried out break process, make its particle diameter less than 5mm;
(2) prepare burden according to following ratio again: mud 70～80 weight parts, cinder 20～30 weight parts; Wherein, the average moisture content of cinder is less than 25%;
(3) afterwards, will put together through the mud of dehydration with through the cinder that break process is crossed and mix, and carry out homogenizing and handle, obtain mixture;
(4) again after, at normal temperatures the said mixture stockpile is placed on indoor maintenance 24～72 hours, carry out ageing and handle;
(5) then, under the extrusion pressure of 0.6～0.8Mpa, will make wet adobe, and allow the adobe seasoning of wetting, obtain dried brick through the mixture that ageing was handled with vacuum extruder;
(6) last, dried brick is carried out roasting, make its temperature reach 980～1020 ℃ and under this temperature constant temperature keep half an hour, obtain finished bricks.
Take such scheme, have the following advantages:
Because method of the present invention is that raw material is produced fragment of brick with pure sludge and cinder, change with pure clay as traditional brick-making method of raw material into being the novel brick-making method of raw material with pure sludge and cinder, do not need clay, can not destroy the arable land, can not cause and fall into disuse the arable land.
Again because brick-making method of the present invention, be to be raw material with pure sludge and cinder, not only solved the sludge treatment problem in the rivers,lakes and seas desilting process, also avoided because mud is piled up the face of land or ploughed and go up destruction that the arable land is caused and the pollution that environment is brought.Therefore, with method brickmaking of the present invention, be the good job that kills two birds with one stone.

Embodiment one:
Get cinder earlier ready, and cinder is carried out fragmentation, make its particle diameter less than 5mm with the sharp agricultural board 70 type pulverizers of the agricultural tile machinery of Wuxi City profit group company production.Wherein, the average moisture content of cinder is less than 25%.
Meanwhile, mud is dug out from Taihu Lake, and carry out airing in the sun, make its water ratio, carry out processed less than 30%.
Again according to mud: cinder=part by weight of 70: 30 takes by weighing the mud and the broken cinder of process of process dehydration.
Afterwards, will put together through the mud of dehydration with through broken cinder, stir, carry out the homogenizing processing, obtain mixture with the sharp agricultural board 240 type biaxial rneaders that the agricultural tile machinery of Wuxi City profit group company produces.
Again, at normal temperatures the said mixture stockpile is placed on indoor maintenance 25 hours, carries out ageing and handle.
Then, the sharp agricultural board 450 type two-stage vacuum brick extruding machines of producing with the sharp agricultural tile machinery of Wuxi City group company, under the extrusion pressure of 0.8Mpa, will make 240 * 115 * 53mm through the mixture that ageing was handled
3The wet adobe of standard, and allow the wet adobe seasoning of these standards become dried brick.Wherein, the vacuum tightness of 450 type two-stage vacuum brick extruding machines is-0.9Mpa.
At last, the above-mentioned dried brick brickkiln of packing into is carried out roasting, make its temperature reach 1020 ℃ and under this temperature constant temperature keep half an hour, make finished bricks.
Embodiment two:
Get cinder earlier ready, and cinder is carried out fragmentation, make its particle diameter less than the 5mm particle diameter with the sharp agricultural board 70 type pulverizers of the agricultural tile machinery of Wuxi City profit group company production.Wherein, the average moisture content of cinder is less than 25%.
Meanwhile, mud is dug out from Taihu Lake, and carry out airing in the sun, make its water ratio, carry out processed less than 30%.
Again according to mud: cinder=part by weight of 75: 25 takes by weighing the mud and the broken cinder of process of process dehydration.
Afterwards, will put together through the mud of dehydration with through broken cinder, stir, carry out the homogenizing processing, obtain mixture with the sharp agricultural board 240 type biaxial rneaders that the agricultural tile machinery of Wuxi City profit group company produces.
Again, at normal temperatures the said mixture stockpile is placed on indoor maintenance 50 hours, carries out ageing and handle.
Then, the sharp agricultural board 450 type two-stage vacuum brick extruding machines of producing with the sharp agricultural tile machinery of Wuxi City group company, under the extrusion pressure of 0.7Mpa, will make 240 * 115 * 90mm through the mixture that ageing was handled
3The wet adobe in 20 holes, and allow these wet adobe seasoninies become dried brick.Wherein, the vacuum tightness of 450 type two-stage vacuum brick extruding machines is-0.085Mpa.
