The device comprises a water pump and is characterized by further comprising an airing plate and a conveying belt. A water pumping pipe is installed on a water outlet of the water pump, a wide opening device is arranged at a water inlet of the water pump, a blocking net is arranged on the wide opening device, the conveyor belt is arranged in front of the blocking net, a part of the conveying belt is arranged underwater, the other part is arranged on the shore, and an included angle of 110-140 degrees is formed between the conveying belt under water and the conveying belt on the shore. By means of the collecting and airing device, the duckweeds are directly fished on the airing plate with the thickness under the natural condition of water, the problem that the duckweeds are difficult to collect is solved, airing is convenient, and working efficiency is greatly improved. The collecting and airing device has the advantages of being simple in structure, easy to construct, less in investment, less in consumption and high in efficiency. The device is arranged on the water side, is not limited by natural environment, and allows automatic collection.
Description
Technical field
The utility model relates to a kind of semi-automatic duckweed collection, drying device, is specially adapted to highly effective gathering and the airing of duckweed in the cultivation of scale duckweed and sewerage treatment river course.
Background technology
Due to the dramatic growth of China's population and industrial fast development, the behavior that sanitary sewage and organic industrial sewage are discharged in each rivers and pond happens occasionally, thereby cause the pollution of surface water, this is also to causing eutrophication in various degree to the rivers of nationwide.Therefore how to implement effective control and the regulation to body eutrophication, oneself becomes the focus that common people pay close attention to.At present, utilize aquatic, terrestrial plant recovery technique, aspect improvement eutrophic water, obtaining certain effect.
Duckweed is Lemnaceae (Lemnaceae) aquatic vascular plant, is distributed widely in all over the world, and the whole world totally 4 belongs to 30 kinds, and there are 6 kinds of 3 genus in China.Because it has good nitrogen, phosphorus absorptive capacity, all the time it be all water body purification pionner (Yin Wanfen, the comprehensive development and utilization of the main ticket plant and of its applications of China, resources conservation and comprehensive utilization, 1998,2:46-48).But because its reproduction speed is very fast, bright Li Shizhen (1518-1593 A.D.) is at < < Compendium of Materia Medica > > medium cloud: " a Ye Jing place i.e. raw number leaf ", if can not remove in time prolific individuality in water body, it also can be because rotting to cause the secondary pollution of water body.
And at present, along with the fast development of Biological Energy Industry, the fuel fermentation of seeking non-grain material is extremely urgent.Duckweed because of its biomass large, it is auspicious that its amount of dry matter can reach 55t/ha.yr(Shen root, with duckweed, purify nitrogen-phosphorus wastewater mechanism and Optimizing Technical research thereof, Zhejiang University's 2005 boundary's doctorate papers), content of starch height was also once becoming model's representative (Duckweed as a cost-competitive raw material for biofuel production dx.doi.org/10.1021/ie3034703|Ind.Eng.Chem.Res.) of new bio energy-source plant.The water body purification effect of duckweed and the value of bioenergy are combined, can not only effectively solve duckweed secondary pollution problem in water body purification process, and can greatly improve the degree of its recycling.
But duckweed, because individuality is small, need to consume a large amount of resources and manpower, and all there is certain defect in existing method and apparatus in reality salvaging and processing procedure.As the duckweed marine salvage equipment that Chinese utility model patent publication number is CN202347508U, this equipment is unstable, is subject to environmental limit larger.The shortcomings such as in addition, a kind of duckweed refloatation device that China Patent Publication No. is JN101806051A, exists device structure complexity, not easy to operate.And the utility model patent cultivates in the practice of salvaging and airing in a large number in duckweed, the problem existing for above-mentioned patent, spy develops a kind of novel half multi-functional automatic equipment that integrates a large amount of collections of duckweed and airing.This is undoubtedly for the higher value application of duckweed in sewage disposal process provides effective guarantee.
Utility model content
In order to overcome the difficult problem that in duckweed large-scale cultivation and sewage purification process, duckweed colony gathers, the utility model provides a kind of semi-automatic duckweed collection, drying device, and this device is integrated by duckweed collection and airing, can greatly reduce working strength and cost.
The utility model technical solution is:
The utility model comprises: suction pump, also comprise airing plate, conveyer belt, drinking-water pipe is installed on water outlet of water pump, the water inlet of suction pump is provided with wide-mouth device, wide-mouth device is provided with block, and block the place ahead is provided with conveyer belt, and a conveyer belt part is placed under water, another part is placed in bank, and the conveyer belt being placed in is under water 110 ° of-140 ° of angles settings with conveyer belt on the bank.
Described conveyer belt is driven by motor by power transmission shaft.
The utility model suction pump increases water body flow area by the wide-mouth device of water inlet, thereby drives duckweed to concentrate to block place; Then by conveyer belt, drive airing plate that duckweed is collected and is transported to from block and carry out airing on the bank.Dry is as the raw material for standby of bioenergy fermentation.Particularly homemade airing plate and special conveyer belt, duckweed directly can be salvaged on airing plate by the natural conditions thickness on the water surface, so not only solve the problem that is difficult to collection of duckweed, and be convenient to again airing, thereby greatly improved operating efficiency.This equipment has simple in structure, is easy to build, and small investment, consumes less, and efficiency is high, and is based upon waterside, is not subject to the restriction of natural environment, can automation collection etc. advantage, and working stability safety, can increase the oxygen content of water surface simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is arranged on the corner in pool or river course, conveyer belt 1 part is placed under water, another part is placed in bank, and the conveyer belt being placed in is under water 110 ° of-140 ° of angles settings with conveyer belt on the bank, and driven by motor driving wheel 8 makes conveyer belt 1 move along the direction of arrow 2; Airing plate 7 is placed on conveyer belt 1 near water end; Suction pump 5 water inlets connect wide-mouth devices 4, and wide-mouth device 4 adheres to block 3 above, fix a drainpipe 6 water circulation discharge to be got back to original water body on the delivery port of suction pump 5.
During use, first with suction pump 5, in underwater, draw water, make the water flow in pool or river course, driving duckweed to concentrate towards block 3 places, gutter 6 on suction pump 5 will be arranged in the place far away, Huo Qi side, opposite of water inlet, so just can make the water surface form a local circulation; Then staff is placed on conveyer belt 1 one end near the water surface by airing plate 7, then conveyer belt 1 will will be submerged under the water surface with airing plate 7, when again emerging, will adhere to uniformly duckweed, treat that conveyer belt 1 passes to bank by duckweed, staff takes off, and carries out airing.Need to indicate: the material of rectangle airing plate adopts stainless steel, in case get rusty and increase its application life, and at its surface paving one deck trellis gauze, to adhere to better duckweed; A wide-mouth device 4 is installed in the entrance of suction pump 5, expands better water entering surface, increases water surface flow area.The aperture of laying above of device blocks 3, duckweed successfully can be tackled before suction pump, realize the accumulation of duckweed.
