Abstract
The invention discloses a kind of back flushing type cyanophyceae removing retracting device, it is made up of air compressor, connecting tube, switch valve, nozzle, cyanophyceae trapping screen cloth, storage algae case, alignment sensor and switch controller.This device can make cyanophyceae be rapidly separated screen cloth, blows to cyanophyceae store up in algae container, is so possible not only to improve the arresting efficiency of cyanophyceae, it is also possible to extend the service life of screen cloth.
Description
Technical field
The present invention relates to a kind of back flushing type cyanophyceae removing retracting device.
Background technology
The situation is tense for China's body eutrophication, in Taihu Lake, Dian Chi, the area such as Chaohu frequently occur blue algae bloom phenomenon, especially with Taihu Lake blue algae bloom in 2007 for.Wawter bloom destroys Taihu Lake ecosystem, and short-term supplies crisis to cause whole city's industrial and agricultural production and resident living water to occur, causes huge economic loss.The method salvaging cyanophyceae for screen cloth, owing to cyanophyceae itself has certain adhesiveness, the cyanophyceae salvaged easily sticks to screen surface.So not only reduce the efficiency of trapping cyanophyceae, and the most therefore screen life-span declines.In consideration of it, it is contemplated that explore a kind of back flushing type cyanophyceae removing retracting device, simple in construction, consume energy less, with low cost, the cyanophyceae trapping for full automatic high efficiency provides the foundation.
Summary of the invention
The technical problem to be solved in the present invention is to propose a kind of back flushing type cyanophyceae removing retracting device.
For realizing above-mentioned technical purpose, the invention provides a kind of back flushing type cyanophyceae removing retracting device, this device is made up of air compressor, connecting tube, switch valve, nozzle, porous sieve plate, cyanophyceae trapping screen cloth, storage algae case, alignment sensor and switch controller.
Described storage algae case is for reclaiming the cyanophyceae of desorption after cyanophyceae trapping screen cloth described in described nozzle blowback；Described nozzle is connected with described switch valve, and its side is equipped with described alignment sensor；The signal that described alignment sensor obtains is after described switch controller processes, to control the state opened and close of described switch valve；Described switch valve is connected with air compressor by described connecting tube.
The workflow of invention is:
When described cyanophyceae trapping screen cloth is near described nozzle, the distance at the described cyanophyceae trapping screen cloth back side and described nozzle bottom surface is now detected by described alignment sensor, when reaching setpoint distance, after described switch controller receives the signal of described alignment sensor, send rapidly instruction.Now, described switch valve is opened, and compressed air blows in described nozzle, then directly blows out from described porous sieve plate, and so cyanophyceae in described cyanophyceae trapping screen cloth front has just been blown to inside described storage algae case.Then, described switch valve cuts out, and described cyanophyceae trapping screen cloth leaves described nozzle and continues trapping cyanophyceae, and after completing trapping, described cyanophyceae trapping screen cloth carries out blowback recovery near described nozzle.So constantly circulation, it is achieved blowback takes off algae, this device high-efficiency environment friendly, and simple in construction consume energy less, with low cost, automatically catches algae for realization and takes off algae and lay the first stone.
Accompanying drawing explanation
Fig. 1 is the work structuring schematic diagram of a kind of back flushing type cyanophyceae removing retracting device.
Fig. 2 is the structural representation of nozzle.
Detailed description of the invention
As it is shown in figure 1, the present invention includes air compressor 1, connecting tube 2, switch valve 3, cyanophyceae trapping screen cloth 5, storage algae case 6, alignment sensor 7 and switch controller 9.After cyanophyceae trapping screen cloth 5 completes to trap the cyanophyceae stage, when entering cyanophyceae removing recovery stage, the position of porous sieve plate 8 adjusting nozzle 4 is parallel with the position of cyanophyceae trapping screen cloth 5, the porous sieve plate of nozzle 4 is positioned at the surface of cyanophyceae trapping screen cloth 5 simultaneously, and spacing distance between the two is detected by described alignment sensor 7.When detecting that distance between the two reaches distance value set in advance, switch controller 9 controls switch valve 3 and opens, and after continuing blowback several seconds, switch controller 9 controls switch valve and cuts out, and completes blowback and takes off algae process.The cyanophyceae 10 of desorption falls directly in the storage algae case 6 being arranged in immediately below porous sieve plate.After cyanophyceae trapping screen cloth 5 completes to remove recovery stage, leave desorption region, be again introduced into the trapping stage.
As in figure 2 it is shown, nozzle 4 is in rectangular shape, its bottom surface, equipped with porous sieve plate 8, can make compressed air than relatively evenly trapping screen cloth 5 back side from bottom surface blowback to cyanophyceae.The entrance of nozzle has been designed to half tubaeform, compressed air thus can be made to compare and evenly diffuse throughout in nozzle 4, makes compressed air than relatively evenly blowing out bottom nozzle 4.
In order to explain above-mentioned embodiment more fully, below with regard to the capital equipment of back flushing type cyanophyceae removing retracting device: nozzle 4, it is described further.The structure of nozzle is as in figure 2 it is shown, its sole arrangement porous sieve plate 8, and compressed air blows to cyanophyceae trapping screen cloth 5 back side by these sieve apertures.Wherein, the pore size of porous sieve plate 8 is relevant with actual blowback target.In view of compressed-air actuated character, the entrance of nozzle 4 has been arranged on the side of nozzle 4, and tubaeform in half.Compressed air after more than half flaring entrances, the ratio inner space being relatively evenly filled with nozzle 4, it is to avoid the compressed air the concentrated destruction to nozzle 4.Owing to compressed air has certain pressure, the material of nozzle 4 also to have certain anti-pressure ability.The outlet of nozzle 4 is directly to be connected with switch valve 3, and switch valve 3 is then directly connected with air compressor 1 by connecting tube 2.
Additionally, the nozzle 4 of design is shaped as cuboid in the above-mentioned detailed description of the invention of the present invention, only preferred embodiment, may be used without other shapes such as cube shaped, the short cylindrical bodily form when being embodied as.
Above-mentioned detailed description of the invention is used for illustrating the present invention; it is only the preferred embodiments of the present invention; rather than limit the invention; in the protection domain of spirit and claims of the present invention; the any modification, equivalent substitution and improvement etc. making the present invention, both fall within protection scope of the present invention.
