Abstract

A new-type light brick material mixing process is as follows: the river channel silt is pumped into a slurry storage tank by means of cutter-suction dredger, then is injected into the batch hopper placed on the mixing boat by using cutter-suction slurry pump placed on the slurry boat. At the same time the fly ash produced in factory or power plant is fed into the above-mentioned batch hopper placed on the mixing boat by means of self-unloading boat at a self-unloading speed matching with slurry pump, and then the fly-ash and silt mixed slurry material is pumped into the slurry tank on the bank by means of slurry pump, then the obtained slurry material is naturally evaporated or artificially solidified and dewatered to obtain the invented raw material for making bricks.

Description

Novel light brick material mixes and stirs technology

The present invention relates to a kind of technology of mixing and stirring, particularly a kind of novel light brick material mixes and stirs technology.

Common brick is continued to use prosperity always in several thousand and is not declined, trace it to its cause mainly is because clay brick can be gathered materials on the spot, fired on the spot, use on the spot, cheap, superior performance, enough intensity is arranged, applicable to various occasions, be convenient to construction, performances such as ventilative adjusting humidity are arranged.But clay brick will be allowed to lie waste and fetch earth, and strives the field with farming, consume a large amount of energy, does not meet the general orientation of China's building materials development.And the brick material that newly emerges is not ideal, for example: though Dinas brickes it replaced clay with river sand, unit weight is big, makes troubles for transportation and construction, has also increased the loading of whole building simultaneously, the corresponding construction costs that increased.Flyash brick and for example shrinks greatly owing to do, and is subjected to more condition restriction during use, does not consider to use during as design and construction when adopting this brick, just must change design, takes corresponding technical measures, and this has influenced the application of this brick undoubtedly greatly.In recent years emerging novel wall brick has brick of figuline building blocks, expanded perlite building block, structural clay tile, inflation etc., these novel wall materials all have its weak point, regular tenacity is on the low side, the extension that has not slurry, the dried contraction that has is excessive, occurs the crack behind the block, what have also has permeable phenomenon, construction inconvenience etc., these novel wall materials are on the high side simultaneously, are difficult to for the moment promote.

The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part that a kind of shipborne blending station that utilizes is provided, with inexhaustible riverway sludge and increasing, not only took up an area of and stacked but also a large amount of flyash of contaminated environment, the novel light brick material that mixes and stirs into brick-making raw material mixes and stirs technology.

Purpose of the present invention can reach by following measure: a kind of novel light brick material mixes and stirs technology, it is characterized in that: inhale ship with riverway sludge or dredge and complete sludge pumping to mud storage pool by hinge, by the hinge suction slush pump that is located in the mud carrier mud injection is located at the batch hopper that mixes and stirs on the ship, meanwhile the flyash from factory or power plant's generation is discharged into the batch hopper that mixes and stirs on the ship by the self-unloading speed that self-discharging ship and slush pump are complementary, stucco slurry after mixing and stirring is passed through the slush pump pump again to shore-based grey mud pit, can become the brick material after natural evaporation or manual consolidation draining.

Purpose of the present invention can also reach by following measure: the flyash content in the described stucco slurry can be 50%～85%.The described ship that mixes and stirs also can be the blending station that is located at land.

The present invention is described in further detail below in conjunction with (embodiment): embodiment:

Inhale ship by hinge and riverway sludge is pumped into mud storage pool or directly will dredges and complete riverway sludge and unload mud storage pool, inhale slush pump and riverway sludge is injected be located at the batch hopper that mixes and stirs on the ship (or station) by being located at hinge in the mud carrier; With the time simultaneously, transport to harbour from the flyash of factory or power plant's generation and load onto self-discharging ship, from boat to mixing and stirring by the ship, back, upright position is discharged into batch hopper with the self-unloading speed that slush pump is complementary with flyash: after being located at the gauge tap and mixing apparatus under the batch hopper, stucco slurry enters mixes and stirs cabin, again by large-scale slush pump with the stucco slurry pump on the bank the grey mud pit of a plurality of storages, after natural evaporation or manual consolidation draining, promptly can be the brick material, just can transport brick field to for playing the brick use after being transported to storage mud field ageing through digging.

The ash amount of mixing of flyash has following relation in the unit weight of stucco slurry and the riverway sludge: in ooze 50% flyash, unit weight is about 1.37 gram/cm ³In ooze flyash 75%, unit weight is about 1.25 gram/cm ³In ooze flyash 85%, unit weight is about 1.19 gram/cm ³Unit weight and coal, molding mode and roasting all have direct relation in addition.And the intensity of brick is little with flyash amount and the coal relation of oozing, but relevant with roasting, and it is just not by a long sight to burn till one-level brick and seconds intensity.

What of the loss on ignition of flyash are the proportioning of flyash and riverway sludge be according to, rationally allocate mud into, and the existing enough plasticity index that make it to prepare burden do not need extra fuel again.As the fly ash amount is 50%, calorific value 400 kilocalories, and the mud calorific value is 200 kilocalories, does not just need extra fuel during roasting basically.Can suitably allocate some dry powder coal ash or dried mud powder into during rainy season brickmaking, plasticity index is about 10, and this is relevant with the character of oozing ash amount and riverway sludge, and plasticity index also can further improve after ageing, can satisfy the needs of brickmaking fully.

The present invention has following advantage compared to existing technology:

1, this brick material is that effluent road mud and flyash mix and stir and forms, and has effectively solved tradition Brickmaking will be allowed to lie waste and be fetched earth, and strives this especially big difficult problem of field with farming.

2, utilize simple device and the technology of the existing clay brick field of China, adopt our station to provide The brick material just can be produced the sintered coal ash light-weight brick, and is for applying flyash, especially wet Ash has been created wide prospect.

3, the supporting thin equipment of completing of dredging of blending station can advance to dredge to be completed and do, and can utilize these mud and flyash to be mixed with the brick material in conjunction with near harbour basin, navigation channel, is to kill two birds with one stone, and provides effective way for dredging the outlet of completing mud.

4, flyash and riverway sludge particle are very thin, very even through mixing and stirring form slurry, this makes the technology of brickmaking and equipment become very simple and easy, what disintegrating machine, pulverizer, twin rollers even first stir can omit need not, expect that from former process equipment comes a revolution completely will for sintering brickmaking industry.It is similar to make the color of brick and outward appearance and clay brick, and light capacity, and serviceability is more more superior than clay brick, and its intensity surpasses other novel wall material, and price is with regard to considerably cheaper.

5, because raw material is complete sharp useless, and brickmaking technology, device simple, thereby present technique has remarkable social benefit and economic benefit.

6, make a silk purse out of a sow's ear, energy savings, containing in the flyash has a large amount of humus in remaining loss on ignition, the mud, for the roasting of brick provides a large amount of energy, contain the above flyash of 500 kilocalories, interior fly ash 50% is not mixed fire coal in not needing basically during roasting.

7, as being located at the newly-built thermal power plant of fresh water river bank, as establishing blending station and just can be directly flyash and riverway sludge be mixed the brick material and directly supply with contiguous brick field and use, this is to solve the easiest approach of fly ash in electric power plant.
