TW201414420A - Aeration filtration device for cultivation pond - Google Patents

Abstract

The present invention discloses an aeration filtration device for a cultivation pond. The aeration filtration device comprises a filtration box having an accommodation space therein for receiving an iron net basket, a motor pump having a motor and blades driven by the motor, and a gas chamber having an injection port. A to-be-filtered liquid is inputted into the filtration box through a first pipeline, and the filtered liquid from the filtration box is outputted through a second pipeline and a third pipeline. The liquid from second pipeline is drawn into the motor pump as the blades are driven by the motor, and the liquid from the motor pump is transmitted through a fourth pipeline and outputted via a nozzle. The injection port of the gas chamber is located at an outlet of the nozzle. With a relatively high velocity liquid transmitted from the nozzle, the liquid inputted by the third pipeline and the air injected by the gas chamber are mixed and outputted through a fifth pipeline.

Description

Breeding tank air pumping device

The invention relates to a gas filtering water filtering device, in particular to a filtering tank capable of filtering culture water, and having a filter box which is convenient for cleaning, and a gas filtering device for aquaculture pool which is simultaneously pumping the breeding pool.

Most of the air pumping or water filtering devices currently used in the culture tanks are separately different devices. The air pumping device usually drives the air into the water by means of a waterwheel, and the filtering device filters out the impurities in the water. However, the two devices are not only expensive to use, but the conventional filtering device is usually fixed under the water surface, which is very inconvenient when the filter needs to be replaced. If the filter is not replaced for a long time, the algae in the water will increase. Causes eutrophication and is not conducive to the growth of aquaculture.

In view of the above problems of the prior art, the object of the present invention is to provide a culture tank air filtering water filter device, so that the aquaculture industry can conveniently clean the filter box for filtering the culture water, and the device can simultaneously pump the breeding pool to avoid The culture pond water is highly nourished or deprived of oxygen, which leads to the death of the cultured aquatic products.

According to one aspect of the present invention, a culture tank air pumping device is proposed. The aquaculture water pumping device comprises a filter box having an accommodating space for accommodating the iron mesh basket, the filter box inputs the liquid to be filtered through the first pipeline, and the filtered liquid is passed through the second pipeline and Third line output; motor a pump, which drives the blade with a motor to draw the liquid of the second pipeline into it, and is outputted by the fourth pipeline through the nozzle; the gas chamber has an injection port at the outlet of the nozzle to pass through the nozzle After the liquid of a larger flow rate, the liquid input from the third line is mixed with the air injected into the chamber, and is output through the fifth line.

In the aquamarine water filtering device of the present invention, the filter box may further include an outer cover, and the outer cover is fixed on the filter box with a cassette.

In the aquaculture water filtering device of the culture tank of the present invention, the iron mesh basket may be composed of an iron mesh, which may have holes therein, and the inner side of the iron mesh basket may have a filtering material, and the filtering material may be a non-woven fabric, a filter cloth or a net.

In the aquamarine water filtering device of the present invention, the portion of the air chamber in contact with the air may have a net to prevent dust in the air from falling into the air chamber to cause clogging.

In the aquamarine water filtering device of the present invention, the first, second, third, fourth or fifth pipeline connecting the filter box, the motor pump or the gas chamber may further have a joint for connection and Disassembled.

In the aquaculture water filtering device of the aquaculture tank of the present invention, the liquid to be filtered may be sewage or eutrophic water.

As described above, the aquaculture water filtering device of the present invention may have one or more of the following advantages:

(1) The aquaculture water pumping device can enable the aquaculture industry to clean the filter box conveniently and quickly to avoid excessive eutrophication of the culture pond water.

(2) The aquaculture water pumping device of this culture tank can inhale the water while filtering the culture water to maintain a certain oxygen content in the culture pond water. For use in aquaculture.

Please refer to FIG. 1 , which is a schematic diagram of the air pumping device of the culture pond of the present invention. In the figure, the aquaculture water pumping device 1 is floated on the water surface 60 through a PVC float pipe (not shown), and the aquaculture water pumping device 1 can be floated on the water surface 60 by pulling with a tool, such as a wire. The filter tank 10 includes a filter box 10 having a receiving space for accommodating the iron basket 102, and the filter box 10 is input through the first line 402 to be filtered. The liquid is filtered, and the filtered liquid is output from the second line 404 and the third line 406. The filter box 10 includes an outer cover 106. The outer cover 106 is fixed to the filter box 10 by a cassette 108. The iron basket 102 The utility model is composed of an iron mesh, has a hole therein, and has a filtering material 104 inside the iron mesh basket 102, and the filtering material 104 is a non-woven fabric, a filter cloth or a net, and the liquid to be filtered is sewage in the breeding pond or eutrophication. Water, which may contain fish feces, floats or algae; motor pump 20, which drives the blade 204 with a motor 202 to draw liquid from the second line 404 therein, and through the fourth line 408 through the nozzle 206 after output; gas chamber 30, the injection port 302 is located at the exit of the nozzle 206, the root White's law of work, the pressure of the faster flow rate in the liquid or gas will be smaller, because the flow rate of the liquid after passing through the motor pump 20 is faster, so that the pressure at the outlet of the nozzle 206 is smaller, and the pressure from the third line is made. The liquid flow rate of 406 will be much larger than that of the fourth line 408, while the liquid injected into the third line 406 and the air injected into the gas chamber 30 by the liquid having a larger flow rate after the nozzle 206. Mixing is performed and the filtered and air-rich liquid is output via a fifth line 410.

In addition, the portion of the plenum 30 in contact with the air may have a net 304 to prevent dust in the air from falling into the plenum 30 and causing clogging of the injection port 302.

In addition, in FIG. 1, the first line 402, the second line 404, the third line 406, the fourth line 408 or the fifth line 410 are connected to the filter box 10, the motor pump 20 or the gas chamber 30. The portion may have a joint for connection and disassembly, for example, the filter box 10 is connected to the first line 402 through the joint 502, the second line 404 is connected through the joint 504, and the third line 406 is connected through the joint 506; The pump 20 is connected to the fourth line 408 through the joint 508, and the nozzle 206 is attached to the joint 508 in the figure; and the third line 406 is connected to the injection port 302 and the nozzle 206 of the gas chamber 30 through the joint 510. Exit location.

Finally, after the filter material 104 in the filter box 10 is used for a period of time, a lot of filtered impurities remain thereon. At this time, the farmer can open the outer cover 106 of the filter box 10, take out the entire iron mesh basket 102 and replace the filter material. 104. The filtered impurities on the filter material 104 can also be removed as a fertilizer.
