Abstract
The present invention relates to a drum screen for fish farms, and to reduce the load of the sorting tank for purifying the contaminated water discharged from the fish tank of the fish farm and to ensure that the power source and the power source is normally transmitted even if the sorting barrel is inclined.
The fish farm drum screen according to the present invention includes a hollow case 10 having an inlet 11 and an outlet 12; A sorting barrel 20 installed rotatably in the case and provided with a sorting network 22 around the case to sort and rotate a foreign substance in the contaminated water introduced into the case; A washing water spraying means (30) installed at the periphery of the sorting barrel and spraying the washing water to drop foreign substances sorted by the sorting barrel from the sorting barrel; A foreign matter collecting container (40) fixed to the inside of the sorting container and receiving a foreign matter separated from the sorting container by the washing water spraying means; A drive source 50 for rotating the sorting cylinder in place; And, it is composed of a plurality of support rollers (60) which are rotatably installed on both sides of the lower side from the center of the sorting barrel to support the sorting cylinder from the bottom.
Description
The present invention relates to a drum screen for fish farms, and more particularly, to reduce the load of the sorting tank to purify the contaminated water discharged from the fish tank of the fish farm and to damage the material by allowing the power source and the normal power transmission even if the sorting barrel is inclined The present invention relates to a drum screen for fish farms that can prevent malfunctions and simplify the structure.
In general, water contained in aquaculture tanks, such as fish farms, which farm various fish, is easily contaminated by ammonia (NH3), nitrous acid (HNO2), and food waste of various wastes generated during fish farming.
If the pollution is left unattended, there is a risk that fish may die from various diseases, and if the polluted water is discharged to the outside of the tank as it is, there is a risk of secondary pollution.
As such, a conventional method for purifying water contained in a fish farming tank is, for example, a circulation type in which the water in the tank is continuously discharged by a predetermined amount, purified by a drum screen, and then supplied with purified water to the tank.
Of course, the purification system is provided in addition to the drum screen, but the present invention relates to the drum screen, so only the drum screen will be described in detail.
As shown in Fig. 1 and Fig. 2, the fish

The conventional fish farm drum screen configured as described above has the following problems.
Since the sorting
In addition, since the
In order to solve this problem, there is a conventional technology that does not use a rotating shaft.
As shown in FIG. 3, the case is equipped with a plurality of support rollers 8 (shown in two in the drawing) for supporting the
According to this conventional technique, the structure is simplified because the rotating shaft is not used. However, since the supporting
The present invention is to solve the above problems, and to simplify the structure by rotating the screening cylinder without using a rotating shaft, reducing the frictional resistance of the screening screen by reducing and dispersing the self-weight and dynamic load of the screening, It is an object of the present invention to provide a drum screen for fish farms in which the driving source and the sorting can keep the connection state even if the inclination of the can occurs.
Fish farming drum screen according to the present invention for achieving the above object, the case and the fluid tank is connected in fluid communication; A sorting passage installed in the case so as to be rotatable in place and having a sorting network at a periphery to sort and rotate a foreign substance in the contaminated water introduced into the case; Washing water spraying means which is installed at the periphery of the sorting box and sprays the washing water to drop foreign substances sorted by the sorting box from the sorting box; A foreign matter collecting container which is fixed to the inside of the sorting box and receives a foreign matter separated from the sorting box by the washing water spraying means; A drive source for rotating the sorting cylinder in place; And, it is characterized in that it comprises a plurality of support rollers which are installed to be rotated in place on both sides of the lower side from the center of the sorting barrel to support the sorting cylinder from the bottom.
According to the drum screen for fish farms according to the present invention, since the support roller is supported at the bottom of the sorting barrel, the load applied to the support roller is less than when the support roller is suspended from the upper conventionally, so that the driving load of the sorting barrel is reduced. Accordingly, power consumption of the driving source can be reduced. And, the slip between the support roller and the sorting can be prevented to reduce the friction between the sorting bucket and the support roller can improve the durability of the material and extend the life.
In addition, even if the sorting box sag, the joint connecting the driving source and the sorting box can be normally delivered without breaking, thereby significantly reducing maintenance costs.
