Description

  The present invention integrally forms a bubble separation tank in a filtration device that feeds live fish such as live fish and aquaculture tanks, etc., and purifies the water quality by efficiently filtering and removing organic substances and pollutants by reducing the overall size. The present invention relates to a biological filtration apparatus with a foam separation tank for the purpose of improving the breeding of various seafood.

Conventionally, this type of foam separation tank uses a flat storage tank, foam separation tank, sterilization tank, heat exchange tank, etc., between the storage tank and the filtration tank inside the live fish farming device body. What is composed is known. (For example, registration 3107060 gazette)
Furthermore, in the conventional filtration device, a filtration tank, a sterilization tank, and a water storage tank are integrally formed inside, and the height of the partition wall adjacent to the drainage tank is the same height as the drainage tub, so that sludge becomes a sterilization tank. Some of them have been prevented from entering. (For example, refer to JP 2004-58034 A)

Although the former thing described in the conventional one uses a foam separation tank, the foam separation tank is integrated with a storage tank between the storage tank and the filtration tank provided in the storage device. Since it is formed in a very small size, it is impossible to purify a large amount of filtration of organic substances and filtration of pollutants, and there is a problem that the efficiency of the filtration tank is extremely poor. .
In the latter case, a foam separation tank is provided in the filtration tank, and the cleaning action of organic matter and sludge is remarkably poor and easily contaminated, so that cleaning becomes a very troublesome work. There is.
Furthermore, since the conventional foam separation tank device is manufactured and sold as a single device product, it is very expensive, so it is very large to be installed in a filtration device having an important filtration action. Therefore, there is also a problem that is economically inappropriate.
The present invention is intended to solve the above-described conventional problems. The purpose of the present invention is to provide a filtration device separately from conventional storage tanks and breeding aquariums for live fish. By incorporating a foam separation tank into one body, filtering organic matter acts as a pretreatment of the filtration tank, adsorbing pollutants to the bubbles, removing bubbles efficiently using the bubbles as a filter, and circulating water to breeding tanks, etc. Thus, clogging of the filter medium due to filtration can be remarkably prevented. Moreover, a foam separation tank is installed in the filtration device higher than the position of the filter medium to facilitate cleaning of the polluted discharge and the backwash of the pollutant in the filter medium.

  In order to achieve the above object, the filtration device with a foam separation tank of the present invention has a substantially square shape, and the position of the filter medium of the filtration tank that integrally constitutes the internal filtration tank and the foam separation tank. The foam separation tank is provided below the inside of the filtration tank and forms a filter medium washing drainage catchment for backwashing on the outer periphery of the filter medium, and is installed above the filter medium filling position.

Since the present invention is configured as described above, as compared with a conventional filtration device that does not have a foam separation tank, the contaminants are floated by bubbles, so the filter material for filtration is clogged significantly. Along with the effects that are prevented, there are also effects that help activate the filtering bacteria.
And since the upper end of the foam separation tank provided in the main body of the filtration device is located above the upper part of the filter medium, the polluted waste is adsorbed by the fine bubbles and floats, and the running water in the water supply tank is sent without being significantly contaminated. effective. In addition, depending on the filter media cleaning drainage catchment provided on the outer periphery of the filter media, the contamination accumulated by the backwashing of the filter media by the bottom cleaning device is reliably sent to the water tank by the filter media cleaning drainage catchment vessel. There is also an effect that can be discharged from the bottom of the aquarium.

According to the present invention, as shown in FIG. 1, the filtration device main body supplies circulating water to the foam separation tank adjacent to the filtration tank by the circulation pump, and is generated by rotation of the internal foam separation device main body blade (impeller). Fouling substances are levitated by fine bubbles, discharged from the upper polluted water distribution pipe, sent to the water tank from below, passed from the water tank through the filter medium as shown by the arrow, and sent to the water storage tank / sterilization tank, as necessary The sterilizer is obtained and sent to the filtration tank.
Furthermore, when the filter medium is clogged with contaminants, the contaminants are lifted by backwashing using a cleaning device with a cleaning blower and returned to the water supply tank with the filter medium cleaning drainage catchment. It is discharged to the outside with a drain pump.

Next, an embodiment of the present invention will be described with reference to the drawings. The filtration device main body (1) is formed in a substantially rectangular shape as a whole, and is provided with a filtration tank (2) containing a filter medium (11) in the center. A foam separation tank (3) and a water supply tank (4) are installed adjacent to each other. A water storage tank / sterilization tank (5) is integrally installed at the other end of the filtration tank (2).
Next, in the filtration tank (2), the position of the internal filter medium (11) is stored below the internal position of the filtration tank (2). On the outer periphery where the filter medium (11) is stored, a drainage water collecting tank (6) for cleaning the filter medium for backwashing and discharging the pollution as indicated by an arrow is disposed.

A disperser (20) for generating fine bubbles is installed. Further, a rotating shaft (22) of a vertical ventilation pipe connected to the aeration device (7) is provided inside, and a fine bubble generator (21) is attached to the lower end.
Further, the foam separation tank (3) is connected to a polluted drain pipe (27) provided with a pollutant discharge port (28) in the upper part and a circulation pump (12) through a circulating water outlet pipe (26). A water amount adjusting valve (19) is provided.
In addition, a perforated plate (18) is laid at the lower end of the filter medium (11), and a cleaning device (17) is installed at the lower part thereof. An air pipe (23) is connected to the cleaning device (17), a cleaning blower (14) is connected to the air pipe (23), and an air relief valve (15) is installed on the way. It is.

The sterilizer (9) is equipped with a quartz tube / ultraviolet lamp (10). In addition, a filtration tank (36) is provided adjacent to the water storage tank / sterilization tank (5). The filtration tank (36) is provided with a cleaning water supply valve (30) and connected with a cleaning water supply pipe (33). The filtration tank (36) is provided with a filtered water outlet (32) and a drain valve (29) via a drain pipe (31). The code | symbol (16) shows the drain valve (16) provided in the drain pipe (24) provided in the lower end of the water tank (4), and the code | symbol (8) shows the level switch provided in the water tank (4). Reference numeral (25) denotes an air hose connected to the fine bubble generating disperser (20).
