Abstract
The utility model relates to a back-flushing type percolating filter for the transportation of living fishes, which comprises a box body, a water pump, an inlet gate valve and an outlet gate valve. The percolating filter has the following characteristics that: the water pump, the inlet gate valve and the bottom of the box body are sequentially connected, the bottom of the box body is a water storage area, the middle of the box body is provided with a plurality of filter layers, and the top of the box body is a clean water area, and is connected with the outlet gate valve. The utility model adopts the filtration method to remove suspended matters in the water body with living fishes, thus ensuring the cleanness of the water, and the utility model is suitable for the long-distance transportation of living fishes, and can increase the livability of fishes.
Description
Technical field
The utility model relates to a kind of backpulsing permeation filtration device that is used for the live fish transportation, particularly a kind of backpulsing permeation filtration device that is used for live fish transportation purifying water body.
Background technology
In the live fish transportation, because secretion and excreta in the fish body are constantly discharged, cause the outstanding absurd creature of water body to be on the increase, if untimely the processing, to make mucus, peel off fragment of tissue, outstanding absurd creature such as organic matter is attached to fish body gill opening, influences the area of available gas exchange, causes the difficulty of taking the photograph oxygen, and easily cause the microorganism raised growth, the oxygen in the water is reduced.Therefore, in time remove the outstanding absurd creature in the water, to the cleanliness of increasing water quality, for fish provides good living environment necessary.
Summary of the invention
The purpose of this utility model is that a kind of backpulsing permeation filtration device that is used for the live fish transportation will be provided, and it adopts the method for filtering, and removes the outstanding absurd creature in the live fish water body, guarantees clean water quality, is highly suitable for the remote transportation of live fish, improves the survival rate of fish.
A kind of backpulsing permeation filtration device that is used for the live fish transportation described in the utility model, it comprises casing, water pump, water inlet gate valve, goes out Water gate valve, it is characterized in that: water pump, water inlet gate valve and bottom half are linked in sequence, bottom half is a water retention zone, the middle part of casing is provided with some filter courses, the top of casing is a clean water area, and with go out Water gate valve and be connected.
Filter course described in the utility model divides three layers, is respectively fine sand layer, activated carbon layer, corallite layer from the bottom to top, and its thickness ratio is 5: 3: 2, and the bolting silk net is established in the bottom of each filter course.
The bottom of the utility model casing is skewed, and the bottom surface becomes 10 ° with horizontal sextant angle, and the blowdown friction top is established in the bottom half bosom.
The utility model casing is a rectangle, and the ratio of length is 2: 1: 1.6, and the height of casing top clean water area is 10% of a casing total height, and the height of bottom half water retention zone is 20% of a casing total height.
The beneficial effects of the utility model are, because water pump is installed in the bottom at filter, make sewage carry out the backpulsing permeation filtration with pressure, the productivity ratio height that filters, effective, and the casing top is provided with clean water area and keeps certain height of water level, can further precipitate again, and it is blocked to guarantee that filtering material is not easy.

Fig. 1 is the utility model schematic diagram.
Among the figure: 1. water inlet gate valve 2. goes out Water gate valve, 3. blowdown friction top, 4. water pump, 5. water retention zone, 6. filtering area, 7. fine sand layer, 8. active carbon layer, 9. corallite layer, 10. clean water area, 11. casings.
Embodiment
A kind of backpulsing permeation filtration device that is used for the live fish transportation described in the utility model, as shown in Figure 1, it comprises the casing of making of glass-reinforced plastic material 11, water pump 4, water inlet gate valve 1 goes out Water gate valve 2; Water pump 4, water inlet gate valve 1 are linked in sequence with bottom half, bottom half is a water retention zone 5, the filtering area 6 at the middle part of casing 11 is provided with the three layer filtration layer, be respectively fine sand layer 7, activated carbon layer 8, corallite layer 9 from the bottom to top, its thickness ratio is 5: 3: 2, and the bottom of each filter course is established the bolting silk net and isolated.The top of casing is a clean water area 10, and with go out Water gate valve 2 and be connected.The bottom of the utility model casing is skewed, and the bottom surface becomes 10 ° with horizontal sextant angle, and blowdown friction top 3 is established in the bottom half bosom.The utility model casing is a rectangle, and the ratio of length is 2: 1: 1.6, and the height of casing top clean water area is 10% of a casing total height, and the height of bottom half water retention zone is 20% of a casing total height.
Operation principle: open into water gate valve 1 and go out Water gate valve 2; close blowdown friction top 3; the sewage that water pump 4 will filter fish hold is squeezed into water retention zone 5; sewage in the water retention zone 5 is under the operating pressure of water pump 4; enter filtering area 6, begin infiltration, most outstanding absurd creature (secretion and excreta) in the fish hold water body is blocked in orlop from fine sand 7; thereby the surface of protection active carbon layer 8 and corallite layer 9 is avoided adhering to of outstanding absurd creature and is stopped up, and influences the adsorption filtration effect.Water body further to active carbon layer 8,9 infiltration of corallite layer, arrives clean water area 10, and at this moment opened owing to going out Water gate valve 2, the water purification after the filtration flows back to fish hold automatically, finishes a filtration cycle.When the work that water pump 4 does not stop, the water purification after the filtration also flows back to fish hold continually.When the needs cleaning and filtrating equipment, close into water gate valve 1 and go out Water gate valve 2, open blowdown friction top 3 rapidly, rely on the water of clean water area 10 and water retention zone 5 to be deposited on undermost dirt from the gravity flushing, water quality also can obtain effective filtration, purification when guaranteeing next the transportation.The function of three kinds of filtering materials is: the effect of fine sand is to stop outstanding absurd creature; The effect of active carbon is a decolouring and deodorizing; The effect of corallite is to absorb ammonia nitrogen.The utility model is simple in structure, easy operating, and good filtration effect, and flushing is convenient.
