Description

A kind of blue algae collecting system

Technical field

The present invention relates to a kind of blue-green algae fishing process device.Be a kind of gathering system of collecting water-surface blue-green algae specifically.

Background technology

Eutrophic water body outburst algae forms wawter bloom, is a global problem.In China, because the surge of rapid economic development and population, produce with domestic pollutant and enter water body in a large number, landlocked rivers, water body in lake and offshore waters are subjected to severe contamination, blue-green alga bloom, green alga wawter bloom and red algae wawter bloom take place frequently, toxic substance, odor causing substance and the organism that the mass mortality algae discharges be to making local water quality and Air quality severe exacerbation, and jeopardize fishery and drinking water safety.According to years of researches, lake wawter blooms such as China Dian Chi, Taihu Lake, Chaohu mainly are blue-green alga blooms, based on Microcystis aeruginosa.This class algae is unicellular, sphere, and cell dia is at the 5-10 micron; Blue-green algae cell wall skin is a polysaccharide, has stronger water-retaining capacity, and cell surface is electronegative simultaneously, and cell has repulsive interaction each other; The cell crude protein content is generally at 50-60%, and organic content is more than 85%, and nutrient content is abundant.Salvaging is the important measures of eliminating landlocked water body water bloom pollution, in the Yunnan Province of China Dian Chi, Taihu Lake, Jiangsu, Chaohu, Anhui etc. are employed.At the high temperature season of algal bloom, every day is salvaged blue-green algae more than kiloton in Taihu Lake.Because the water content of fresh and alive blue-green algae cell own is about 90%, the blue-green algae cell of salvaging also exists a large amount of intercellular gravity water and planar water, no matter be to adopt manual method or mechanical means to salvage, the water ratio of bloom blue algae is generally all at 95-99%.Too high water ratio not only brings very big cost to the blue-green algae transportation, brings great difficulty also for the blue-green algae ultimate disposal.If the bloom blue algae of this high-moisture is direct landfill, floor space pollutes greatly and very easily that thing overflows and seepage, if directly carry out processing such as feed and fertilizer, need the in addition detoxification of very big container or facility, hydrolysis or decomposition etc., handle have a big risk, the cost height.Carrying out processed to salvaging blue-green algae, improve the relative ratios of wawter bloom algae mud dry-matter, is to realize wawter bloom safe disposal and the most important link of recycling.

Solve the pollution that algae causes water resources and be used, just must in time salvage and improve the relative ratios of wawter bloom algae mud dry-matter algae.Have artificial at present and the machinery salvaging, machinery is salvaged the pumps that adopt more and is taken out.System's manufacturing process complexity, the inconvenient operation that common pump is drawn employing causes the cost height, is difficult for promoting.Especially the collection suction nozzle of Shi Yonging, it is less because of pipe diameter generally to collect suction nozzle, collects mouthful can not fully satisfy the demand, perhaps collection opening structure complexity, manufacturing cost height, inconvenient operation; Also can suck impurity even add block before the collection suction nozzle when adopting pump to take out, these impurity block conduit, influence the efficient that pump is taken out, even damage power-driven pump; And directly Chou Xi bloom blue algae relative ratios's difficulty of continuing to improve wawter bloom algae mud dry-matter in subsequent disposal is unfavorable for the comprehensive utilization of algae mud.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of blue algae collecting system.Adopt this gathering system, not only improve and salvage efficient, and manufacturing is simple, cost is low, use is easy to operate, avoids the influence of impurity to power-driven pump simultaneously, helps the comprehensive utilization of follow-up algae mud, improve the relative ratios of wawter bloom algae mud dry-matter.

The present invention is achieved through the following technical solutions: comprise the gathering system that conduit, disintegrating apparatus, power-driven pump are formed, disintegrating apparatus, power-driven pump are installed in the rear portion of conduit successively and are linked in sequence with commercially available common pipe; Blue algae water at first sucks by conduit, wherein on the conduit floating block is installed, the longest end of pipeline axial and the outside surface of short end a gravity regulator is installed at least, the plane of the collection interruption-forming of conduit and the angle of conduit central axis are less than 90 degree, and disintegrating apparatus is pulverized all kinds of foreign material and provided power with the fragmentation of part blue-green algae, power-driven pump for system.

Floating block can be block fixing or ring-type is fixed, and quantity is purpose to float pipeline at the water surface, and floating block both can all be block, can all be ring-type also, or existing bulk also has ring-type, should method is simple.

Gravity regulator is to guarantee that collecting mouth is sunken to 1～10 centimetre of underwater all the time by plus-minus gravity counterweight.Can utilize similar platform scale steelyard hook plus-minus counterweight, weldering knot to put thing basket plus-minus counterweight, directly tie up method such as gravity counterweight.Wherein the longest end of pipeline axial and the outside surface of short end a gravity regulator is installed at least is to collect mouth and both can upwards collect and also can collect downwards in order in use to make, at the longest end plus-minus gravity counterweight, at the shortest end add and subtract gravity counterweight when collecting downwards when upwards collecting.The longest end of pipeline axial and the shortest end are that pipeline is collected the inclined-plane of interruption-forming with respect to pipeline axial, the longest end of pipeline axial and the shortest end that form owing to the inclined-plane.

The plane of the collection interruption-forming of conduit and the angle of conduit central axis be 10～30 degree preferably, most preferably 20 degree.

Conduit can be the identical pipeline of diameter.Collection mouthful diameter also can be the pipeline greater than the rear end pipe diameter, forms hydraucone.

Disintegrating apparatus can be the gear pulverizer, pulverize all kinds of foreign material by gear, all kinds of foreign material after the pulverizing and blue-green algae mixing simultaneously continues to grind the proterties that makes the part blue-green algae and changes, and particularly the fragmentation of part blue-green algae is helped the relative ratios of the following process raising wawter bloom algae mud dry-matter of blue-green algae; All kinds of impurity that disintegrating apparatus will suck are pulverized and are sent into power-driven pump again, and ducted like this impurity not only can not block and make the power-driven pump suction cause damage, can not cause damage because of impurity particle makes power-driven pump yet.Disintegrating apparatus also can be other cutting facilitys, as the blade type cutting machine.

Adopt blue algae collecting of the present invention system: cooperate unique collection suction nozzle, disintegrating apparatus is with the impurity and the fragmentation of part blue-green algae that suck, he had both made the power-driven pump service efficiency improve, increase the service life, the more important thing is simultaneously again can be ready for the ratio that improves algae mud dry-matter relatively, and the comprehensive utilization value of follow-up algae mud is improved; The collection mouth of conduit enlarges, and can upwards collect also and can collect downwards, higher, the salvaging better effects if of service efficiency in different environment; The cooperation of collecting suction nozzle and disintegrating apparatus had both made impurity be resolved with the problem of the relative raising of algae mud dry-matter, made the collection suction nozzle can not need to install additional other complicated auxiliary facilitys again; Whole gathering system is because simple manufacturing process and significantly reduce manufacturing cost, reached raise the efficiency, easy to operate, the purpose that reduces cost.
