Description
Technical field:
The utility model relates to one and utilizes mud in the waters such as Hu He to utilize technology, particularly relate to the hard impurities such as a kind of snail of removing in mud, shell, stone, brick and tile, wooden pieces, metal object, cullet, and the equipment of toughness impurity that root of phragmites communis, plastic rope, plastic web, plastics bag and plastic waste paper etc. can be wound around.
Background technology:
Make lake river silt mud really become resource to be utilized effectively, realizing utilization of waste material is original intention of the present invention.As everyone knows, there is the hard impurities such as snail, shell, stone, brick and tile, wooden pieces, metal object, cullet in lake, riverway sludge, and the toughness impurity such as root of phragmites communis, plastic rope, useless fishnet, plastics bag and Polywoven Bag, the effective utilization having influence on mud that the existence of these impurity is serious, brickmaking could be used for after must removing, but as far as is known, not yet find that effective, cheap, ecological impurity removal process removes impurity thing in mud.
[2005] No. 33 files are sent out according to the Office of the State Council, the General Office of the State Council is about the notice, comprehensive [2007] No. 77 of the wealth that advance the energy saving building of materials for wall innovation and spread further, and the Ministry of Finance and National Development and Reform Commission are about the notice printing and distributing " novel wall material special fund imposes use management way ", the People's Government of Jiangsu Province is about notice (No. (2009) 36, Su Zhengfa) " the Jiangsu Province's Development of Novel materials for wall regulations " of printing and distributing Jiangsu Province's Taihu Lake Basin comprehensive environmental improvement embodiment, governments at all levels have all carried out strict land conservation policy, restriction clay brick, forbid that the policy of solid brick is carried out stricter, the encouragement policies advocating mud brickmaking embodies in all multifiles, remove waters mud, become desilting water purification, restoration of the ecosystem, environmental improvement, the effectively the most cheap engineering proposal of the comprehensive management engineering such as water conservancy projects functional rehabilitation, because the refuse impurity in mud has had a strong impact on the comprehensive utilization of mud compared with high added value, for this reason, mud physics impurity-removing method will be the important pushing hands that promotion mud is turned waste into wealth, the scheme of taking stopgap measures of original moving type desilting is made to become the scheme of effecting a permanent cure of deflection type, originally desilting is moved on to by the mud that flood in water is taken out to stack on the bank, press the soil that given up, also secondary pollution can be caused, mud after removal of impurities, can utilize as the industrial raw material of brickmaking and consume, also solve the policy restriction of brick-making raw material simultaneously.
Along with the raising of people's land protection consciousness; various places government has all put into effect land protection measure; not only strict land acquisition; and very strict restriction is proposed to clay-brickmaking, various places have all been set up wall and have been corrected, and emphasis promotes the porous heat-insulating brick of energy-saving material-saving; forbid that entity brick is fired; country has also put into effect corresponding policy of rewards, and therefore people to have high input quantifier elimination and test to porous heat-insulating brick, have developed the heat insulation Self-heat-preservation fire proofing tile of many energy-saving material-savings.To reduce the consumption of brickmaking to farmland earth.In recent years, country increases again the system reason dynamics to river course, lake, reservoir, river embankment, require regularly to remove mud, can water-holding capacity be improved like this, prevent flood, can water ecological setting be optimized again, prevent body eutrophication from producing the generation of the pernicious environmental protection events such as blue-green algae, water quality deterioration, the mortality of hydrocoles anoxic, the more important thing is and eliminate or reduce heavy metal contamination, improve Water quality, improve the drinking-water of people, use the safety of water.But how to process the river course, lake, reservoir, the river embankment mud that clean out and become a people's difficult problem, first will solve depositing of mud, how second utilizes if will solving mud.
Because in mud, water content is high, for slurry lake shape fluid, therefore deposit land occupation area large, big area farmland can be taken, very uneconomical, therefore, the common treatment process of people the mud of taking-up is transported to special threshing ground to carry out natural solarization and dry in the air, and removes the moisture in mud, and then roping uses native unit to brickmaking factory etc., so not only spin cycle is long, and efficiency is low, and trucking costs is high back and forth.For brickmaking enterprise, in brickmaking process, also need to add water humidifying to the mud dried, needing so first dewaters to mud becomes mummification earth, is transported to and uses native unit, then also needs the humidifying that adds water with native unit, can increase the consumption of water like this, waste is serious.Due to the utilization process of mud costly, people are reluctant to utilize.
In order to comply with the policy of existing land protection and environment protection; improve the proportion of utilization of mud; mud is turned waste into wealth; applicant is through studying test for a long period of time; successful design goes out to utilize the firing porous energy-saving material-saving self-insulating brick of mud and a complete set of technique of high strength river channel ecology shore protection brick; being wherein precondition to the removal of impurities of mud, is also the core technology ensureing to fire fragment of brick quality.Owing to containing a large amount of snail in the river silt mud of lake, shell, stone, brick and tile, the hard block such as wooden rod member, and rope, plastic waste paper etc. can be wound around soft material, these impurity are not removed and not only can be damaged mud-soid disintegrator, pug mill, the brick equipments such as single-lead-screw extruding briquetting, and the adobe containing above-mentioned impurity is after high-temperature firing, also can produce and cannot overcome mass defect brick, such as containing snail, shell, the mud of stone is fired into brick body and can produces evagination Blister after immersion humidifying, because snail, shell, the major ingredient of stone is calcium carbonate, calcium oxide is formed after high-temperature firing, calcium oxide is met water and namely can be expanded, by such masonry walls, the planeness of body of wall is difficult to ensure.
The brick body that the mud that can be wound around soft material containing plastic rope, plastic web, plastics bag and plastic waste paper etc. is fired into, brick body is meeting shape hole in brick after high-temperature firing, the force structure of brick body can be destroyed, directly affect the bearing resistance of brick body, there is potential safety hazard with the body of wall that it is built into.
Therefore, successfully use mud to carry out brickmaking, the brick made by guarantee can overcome the deficiencies in the prior art, removal of impurities process must be carried out to mud, applicant is through retrieval, and the domestic method not also being applicable to the removal of impurities of industrialization mud, does not more have special mud impurity removing equipment.
In order to remove in mud the hard impurity such as snail, shell, stone, brick and tile sheet, wooden rod member, metal object, cullet more up hill and dale, and effectively can remove the toughness impurity such as root of phragmites communis, plastic rope, useless fishnet, plastic web, plastics bag, Polywoven Bag, plastic waste paper, applicants have invented a kind of method removing foreign material in the river silt mud of lake, the method comprises the steps:
