Aquaculture feedwater filtration tank
Affiliated technical field
The utility model relates to aquaculture utensil field, especially a kind of filter that is used for the aquaculture feedwater.
Background technology
We know, culture the filtration that fish, shrimp etc. are cultured feedwater at present, be by water pump with in the water suction concrete sedimentation basin, through two, three grades of post precipitations, after entering the filtering ponds that sand, stone are housed again and filtering, enter and culture the pond.Thisly give that the water filtering device floor space is big, filtration time is long, filtration yield is little, accumulate dirt and get rid of trouble (after after a while, could remove with sand, stone etc.), filter quality is poor, does not reach the water quality requirement, and is particularly affected by environment big, as when running into the stormy waves water turbidity, more can not reach the water quality requirement.In addition, the concrete filtration tank can only utilize once, can not move, so cannot reuse, simultaneously, the concrete filtration tank needs very dark ground and supports weight above it, and cost is higher relatively, and construction conditions requires harsh.
Summary of the invention
Available coagulation soil filtration tank can not arbitrarily be moved in order to overcome, the cost height, to construction conditions requirement harshness, the filtration tank floor space is big, the technical deficiency of filtration heterodyne, the utility model provides a kind of breed feedwater filtration tank, this filtration tank not only small investment, floor space is little, be fit to various culture environment of aquatic products and use, and cleaning is convenient, good filtration effect.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the box-shaped tower body, the tower body top is provided with into water distributor box, the tower body inner chamber is fixed with the cone barrel Rose Box through support, the following side of Rose Box inner chamber is provided with filter course, the opening that the conical lid upper end of Rose Box is provided with connects " U " shape water inlet pipe and " V " shape siphon pipe respectively, the other end of water inlet pipe taps into the delivery port of water distributor box, the tank wall upside of tower body is equipped with the water purification outlet pipe that communicates with its inner chamber, the siphonal bending part of " V " shape is provided with siphon destructing tube and the auxiliary siphon tube that communicates with the siphon pipe inner chamber, the other end of siphon destructing tube is positioned at the tower body inner chamber, and the position of the auxiliary siphon tube other end is lower than the siphonal bending part of " V " shape.
The beneficial effects of the utility model are, this filtration tank not only small investment, floor space is little, is fit to various culture environment of aquatic products and uses, and can arbitrarily move, and the dirt that produces when filtering can be discharged at any time automatically, good filtration effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. tower bodies among the figure, 2. former water water inlet pipe, 3. water inlet pipe, 4. water inlet distributor box, 5. siphon pipe, 6. siphon destructing tube, 7. auxiliary siphon tube, 8. effluent trough, 9. water purification outlet pipe, 10. Rose Box, 11. filter courses, 12. dirt discharge grooves, 13. supports.
Embodiment
In Fig. 1, box-shaped tower body (1) adopts fiberglass to make, tower body (1) top is equipped with fiberglass water inlet distributor box (4), water inlet distributor box (4) is separated into two chambeies through dividing plate, be respectively intake antrum and storage tank, the opening of intake antrum bottom links to each other with former water water inlet pipe (2), water storage cavity is connected with " U " shape water inlet pipe (3), the cabinets cavity of tower body (1) is fixed with cone barrel Rose Box (10) through support (13), it at the bottom of the case of Rose Box (10) porous shape structure, the inner chamber bottom of Rose Box (10) is covered with the stone layer from bottom to top successively, coarse sands layer, the filter course (11) that the fine sand layer is formed, opening on the conical lid on Rose Box (10) top connects " U " shape water inlet pipe (3) respectively and falls an end of " V " shape siphon pipe (5), the upper side wall of tower body (1) is fixed with the water purification outlet pipe (9) that communicates with tower body (1) inner chamber, position at tower body (1) internal chamber wall water purification outlet pipe (9) nose end is equipped with effluent trough (8), the another port of siphon pipe (5) is positioned at tower body (1) outside, it highly is lower than down the port position of " V " shape siphon pipe (5) at tower body (1) inner chamber, siphon pipe (5) top is promptly fallen the bending part of " V " shape siphon pipe (5) siphon destructing tube (6) and the auxiliary siphon tube (7) that communicates with siphon pipe (5) inner chamber is installed, the other end of siphon destructing tube (6) is positioned at tower body (1) inner chamber, the conical lid position of Rose Box (10), the position of auxiliary siphon tube (7) other end is lower than the bending part of " V " shape siphon pipe (5), and the downside of siphon pipe (5) and auxiliary siphon tube (7) water side is fixed with dirt discharge groove (12).
When the utility model uses, nature water pumps into the into intake antrum of water distributor box (4) by water pump through former water water inlet pipe (2), undressed natural water covers into, and the dividing plate of water distributor box (4) enters in the water storage cavity, and flow automatically to Rose Box (10) by " U " shape water inlet pipe (3), water is from last and in the flow process, filter course (11) through three-decker filters, the clear water of Chan Shenging enters the gathering ground after filtering, it is the cabinets cavity of tower body (1), when the clear water water level rises to effluent trough (8) position, clear water flows out through water purification outlet pipe (9), as the aquaculture water, the natural water of filtered is in Rose Box (10) in the flow process, suspension is stayed in not disconnecting of filter course (11), cause the increase gradually of filtering layer resistance, thereby impel the water level in the Rose Box (10) constantly to rise, water level in the siphon pipe (5) also constantly rises thereupon, reach down the top of " V " shape siphon pipe (5) when water level, when being the upper end nozzle position of auxiliary siphon tube (7), water falls in this pipe, by auxiliary siphon tube (7), so as to taking away the air in the siphon pipe (5), when the vacuum in the siphon pipe (5) reaches certain value, siphonage just takes place, discharge the floating pollutant in the Rose Box (10), in siphonic process, clear water in tower body (1) the inner chamber gathering ground by filter course (11), (is a stone to filtrate from bottom to top, coarse sand, fine sand) washes.When the underwater in tower body (1) inner chamber dropped to siphon destructing tube (6) nozzle position, air entered siphon pipe (5) inner chamber, thereby has destroyed siphonage, and the backwash of filter course (11) also finishes thereupon, and the utility model enters the work of following one-period.
