The utility model relates to a screen cloth for eluriating zoobenthos in deposit, including reel, the sieve end, outer facade filter screen and bottom screen cloth, the reel is the tube -shape, the sieve end be with the ring -type that the reel bottom suited, the sieve back welding connect in the bottom of reel, the lateral wall of reel is provided with a plurality of outer facade apopores to the lateral wall of reel forms has permeating water and not having the waterproof face of outer facade apopore of outer facade apopore, the cladding of outer facade filter screen is in on the face of permeating water, bottom screen cloth setting is in the sieve is at the end, and the bottom border at the sieve end sets up a plurality of bottoms apopore. The utility model discloses have bottom and outer facade apopore simultaneously, improved water efficiency, improved zoobenthos's elutriation efficiency in the deposit greatly, the utility model discloses simple structure, low in manufacturing cost is honest and clean, the utility model discloses can satisfy the elutriation of great volume deposit, application scope is wide.
Description
Technical field
This utility model relates to a kind of screen cloth, particularly relates to a kind of monitor in sampling process for eluriating the screen cloth of zoobenthos in deposit at water environment biological, belongs to enviromental monitoring equipment technical field.
Background technology
In zoobenthos sampling process, in order to be separated from deposit by bion, generally adopt the mode that screen cloth is eluriated.At present, more common screen cloth includes nylon mesh tulle pocket and stainless steel sift.Wherein, the bolting silk string bag, owing to profile is indefinite and Material Strength is relatively low, is only applicable to less amount of deposit and eluriates operation and need constantly artificial upset；General standard screen only bottom can leach, and when deposit viscosity is higher or rich in plant residue, bottom screen very easily blocks, and eluriates inefficient.In zoobenthos sampling process, the sediment yield generally requiring elutriation is relatively big, and the screen cloth using routine is often inefficient, takes time and effort.
Summary of the invention
This utility model purpose is in that to solve the problems referred to above, it is provided that a kind of for eluriating the screen cloth of zoobenthos in deposit, is specifically realized by techniques below scheme:
A kind of for eluriating the screen cloth of zoobenthos in deposit, including screen frame, the sieve end, alien invasion filter screen and bottom screen, described screen frame is in a cylindrical shape, and the sieve end is the ring-type adapted with described screen frame bottom, and described sieve back welding is connected to the bottom of described screen frame；The sidewall of described screen frame is provided with some alien invasion apopores, has permeable of alien invasion apopore thus the sidewall of screen frame is formed and does not have the impervious surface of alien invasion apopore；Described alien invasion filter screen is coated on described permeable；Described bottom screen is arranged at the bottom of described sieve；And the bottom side edge at the bottom of described sieve is along arranging some bottoms apopore.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: described screen frame is cylindrically.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: the alien invasion at the middle part 3/4ths of described screen frame is described permeable, then forms described impervious surface with described permeable all the other contour alien invasion of 1/4th.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: end 150mm, from 50mm at the bottom of described sieve, is sieved in the base of described permeable described in the top margin of described permeable.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: the diameter of described alien invasion apopore is 3mm-5mm；The spacing of described alien invasion apopore is 30-50mm.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: being internally provided with the support keel of decussation formula at the bottom of described sieve, described bottom screen is arranged on described support keel.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: the diameter of described bottom apopore is 3-5mm, and spacing is 50-100mm.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: described screen frame, the sieve end, make by stainless steel material.
Described for eluriating the screen cloth of zoobenthos in deposit, its further design be in that: described screen frame is symmetrically installed with a pair handle.
This utility model has bottom and alien invasion apopore simultaneously, improves water outlet efficiency, substantially increases the elutriation efficiency of zoobenthos in deposit；This utility model simple in construction, cheap for manufacturing cost；This utility model disclosure satisfy that the elutriation of relatively large deposit, applied widely.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description and specific embodiment, this utility model is further described:
As it can be seen, this is used for eluriating in deposit, the screen cloth of zoobenthos includes screen frame 1, the sieve end 2, alien invasion filter screen 4 and bottom screen 6, and screen frame 1 is in a cylindrical shape, and the sieve end is the ring-type adapted with screen frame bottom, and the sieve end 2 is welded in the bottom of screen frame；The sidewall of screen frame is provided with some alien invasion apopores 3, has permeable of alien invasion apopore thus the sidewall of screen frame is formed and does not have the impervious surface 9 of alien invasion apopore 3；Alien invasion filter screen is coated on permeable upper 10；Bottom screen 6 is arranged at sieve the end；And sieve the bottom side edge at the end along arranging some bottoms apopore 8.
Cylindrically, the alien invasion at the middle part 3/4ths of screen frame is permeable to screen frame, and all the other alien invasion of 1/4th contour with permeable then form impervious surface.The base of permeable is from sieve end 50mm, the top margin sieve end 150mm of permeable.
The diameter of alien invasion apopore is 3mm-5mm；The spacing of alien invasion apopore is 30-50mm.The sieve end, is internally provided with the support keel 7 of decussation formula, and bottom screen is arranged on support keel.The diameter of bottom apopore is 3-5mm, and spacing is 50-100mm.
Screen frame, the sieve end, make by stainless steel material.Screen frame is symmetrically installed with a pair handle 5.
This utility model has bottom and alien invasion apopore simultaneously, improves water outlet efficiency, substantially increases the elutriation efficiency of zoobenthos in deposit；This utility model simple in construction, cheap for manufacturing cost；This utility model disclosure satisfy that the elutriation of relatively large deposit, applied widely.
