Description

Blue-green algae and over-water floats are salvaged machine

Technical field

The present invention relates to a kind of marine salvage equipment, the salvaging machine of particularly a kind of blue-green algae and over-water floats.

Background technology

Activity of human beings can make a large amount of industry, agricultural and domestic refuse enter in the water, and water is polluted.At present, the whole world has the sewage of billion cubic meter more than 4200 to enter rivers,lakes and seas every year approximately, has polluted the fresh water of 5.5 tcms, and this is equivalent to more than 14% of global runoff volume.Owing to enter discarded object in the water, often contain many chemical substances, just make and contain abundant nutrition in the water body that cause some water plants to breed in a large number, blue-green algae is exactly one of them.Blue-green algae often breeds in a large number summer, and forms one deck blue-green and stench floating foam of distinguishing the flavor of is arranged at the water surface, is called " wawter bloom ", and large-scale blue algae bloom is called as " green tide " (with the red tide correspondence of ocean generation).Green tide causes water quality deterioration, exhausts water oxygen gas when serious and causes the death of fish.Even more serious is that some kind (as Microcystis aeruginosa) also can produce toxin (being called for short MC) in the blue-green algae, contains a large amount of MC in about 50% the green tide.MC also is the major incentive of liver cancer except directly fish, people and animals being produced the murder by poisoning.

At present, domestic still do not have be applicable to that administering blue-green algae pollutes, and marine salvage equipment with synthetic job function.The existing method of handling blue-green algae normally adopts net to draw wooden dipper to ladle out artificial salvaging, and operating efficiency is very low, and labour intensity is big, and cost is than higher, poor safety performance, and with environmental landscape require incompatible.

China is a shortage of water resources, the frequent country of water disaster, and gross amount of water resources occupies the 6th in the world, and the occupancy volume per person has only 2500 cubic metres, be about the world per capita the water yield 1/4, arrange the 110th in the world, classified as one of 13 poor-water countries by the United Nations.For many years, China's water resource quality constantly descends, water environment continues to worsen, because polluting the lack of water and the accident that are caused constantly takes place, not only make plant downtime, the agriculture underproduction even total crop failure, and caused bad social influence and bigger economic loss, and seriously threatened social sustainable development, threatened human existence.

In recent years, garbage on water such as domestic big or small lake, rivers pollute more serious, not only influenced the neat and artistic of environment, and ecological environment is polluted, and the water resource that makes the mankind depend on for existence is subjected to quite serious threat.Winter in 2005, the water resource of Song Hua River sheet is polluted, and the Harbin in downstream was cut off the water four days; 2 to 4 July in 2007, Shuyang County, Jiangsu Province tap water cut-off 44 hours, and reason is the not clear pollution group from the upstream.Since the retaining of Three Gorges, the rubbish quantity that each district salvaging point of reservoir area is pulled out from river surface is surprising, and the floating thing that 4 day time picked up has been adorned more than 3000 woven bag, and every bag has 30 to 40 kilograms, and it is without cease that the floating thing on the Changjiang river drags for repeatly, troubling.What relevant departments taked mostly is irregularly artificial way of salvaging, yet this method labour intensity is big, inefficiency, and cycle length has been employed very big manpower and materials often, and effect is not obvious.

Summary of the invention

The objective of the invention is to overcome deficiency of the prior art, provide a kind of blue-green algae and over-water floats to salvage machine, it is rational in infrastructure, automaticity is high.

The technical solution used in the present invention is:

Blue-green algae and over-water floats are salvaged machine, comprise frame, diesel engine, centrifugal blower, air-suction duct, exhaust passage, pod, discharge nozzle, suction nozzle, the work of Diesel Driven centrifugal blower, the upper end of centrifugal blower is communicated with an end of air-suction duct, the lower end of centrifugal blower is communicated with an end of exhaust passage, the other end of air-suction duct is communicated with pod, the other end of exhaust passage is communicated with discharge nozzle, one end of soft suction pipe is communicated with pod, the other end of soft suction pipe connects suction nozzle, is provided with the branch filter screen in the junction of air-suction duct and pod; Frame is provided with wind stopping device, and described wind stopping device is located at the below of pod, and wind stopping device is communicated with pod and exhaust passage; Also be provided with reductor on the frame, described wind stopping device is driven by reductor by diesel engine.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:

As depicted in figs. 1 and 2, the embodiment of the invention comprises diesel engine 1, centrifugal blower 2, air-suction duct 3, pod 4, divides filter screen 5, wind stopping device 6, reductor 7, exhaust passage 8, hose support 9, soft suction pipe 10, suction nozzle 11, frame 12, discharge nozzle 13.

Wind stopping device 6 mainly is made up of impeller, housing, impeller shaft, end cap and bearing, and impeller is made up of a plurality of blades.When impeller rotated, material was entered in several enclosed cavities of impeller by the upper end of wind stopping device 6, along with wheel rotation, flowed out from the lower end of wind stopping device 6.Because the gap of blade between housing be very little, therefore can blocks air from the end to end of wind stopping device 6.

Diesel engine 1 drives centrifugal blower 2 work, one end of air-suction duct 3 links to each other with the top of centrifugal blower 2, the other end links to each other with the top of pod 4, and described air-suction duct 3 is communicated with centrifugal blower 2 with pod 4, also is provided with branch filter screen 5 in the junction of air-suction duct 3 and pod 4.The bottom of pod 4 is provided with the wind stopping device 6 that communicates with it, and wind stopping device 6 communicates with the exhaust passage 8 of its below, and the lower end of centrifugal blower 2 communicates with exhaust passage 8, and the end of exhaust passage 8 connects discharge nozzle 13.On pod 4, also be provided with the soft suction pipe 10 that communicates with it, the end of soft suction pipe 10 connects suction nozzle 11, and frame 12 is provided with hose support 9, is used to support soft suction pipe 10.In addition, also be provided with reductor 7 on frame 12, described wind stopping device 6 is driven by reductor 7 by diesel engine 1.

The operating principle that described blue-green algae and over-water floats are salvaged machine is following (followingly only describes blue-green algae, and over-water floats is same principle and process): diesel engine 1 work drives centrifugal blower 2, during centrifugal blower 2 rotations, produce negative pressure in the soft suction pipe 10, produce malleation in the air-suction duct 3, negative-pressure air-flow sucks blue-green algae through suction nozzle 11, enters pod 4 by soft suction pipe 10.Because the junction at air-suction duct 3 and pod 4 is provided with branch filter screen 5, makes blue-green algae can't enter air-suction duct 3, fall in the wind stopping device 6 in the effect of self gravitation, through above-mentioned steps, reach the purpose that air separates with blue-green algae.Reductor 7 can change into relatively low rotating speed with the high rotating speed that motor produces, to guarantee that blue-green algae falls into exhaust passage 8 smoothly.Air in the pod 4, be inhaled in the air-suction duct 3 after, again through the outlet of centrifugal blower 2 lower ends, enter exhaust passage 8, finally discharge through discharge nozzle 13.Because air-flow 8 moves to discharge nozzle 13 along the exhaust passage, the blue-green algae of whereabouts under the effect of air-flow, is expelled to the storage area of appointment from discharge nozzle 13.

After using blue-green algae and over-water floats salvaging machine, need not net and draw wooden dipper to ladle out artificial salvaging, improved efficient greatly, be suitable for extensive use.
