Abstract

The present invention relates to a filtering device of fish tailings (feed feed residue, biological excreta, waste fish, etc.),

The purpose of the present invention is to discharge the waste from the existing circulation filtration system fish tank breeding tank, and the circulation water outlet is installed along with the fishing net to prevent organisms from escaping the bottom of the breeding tank. However, as time goes by, the tailings are attached to the fishing net, and the exit size (the larger the exit size of the fishing net is sucked up) is gradually narrowed or blocked, and the tailings are increased and deposited on the bottom of the breeding tank. According to the cleaning tank cleaning problem occurs, to remove it, move the organism to another breeding tank, drain the water in the breeding tank and eliminates the inconvenience of the worker directly enters the cleaning tank,

Another purpose is to remove, disassemble, and filter the debris with a circulating filtration facility (eg, drum screen, skimmer, biofiltration tank, etc.) installed in the fish farm, but this device is installed in the breeding tank where the scum occurs. By eliminating filtration to improve the ability to prevent fatal toxic gas in advance, and to reduce the water pollution and frequent changes in fuel costs, labor costs, and contribute to the food intake rate and growth.

As a specific means of the present, devised to achieve the above object;

It consists of the absorption pipe and the discharge pipe installed in the filtering device case equipped with the scum filter net in the process of discharging the water into the circulating water at the same time that the water is supplied from the water supply line.

Principle of action is that the discharge line is installed below the breeding tank underground. The water is sucked into the absorption pipe installed at the bottom of the breeding tank due to the water pressure and water level difference in the breeding tank. This is explained by the principle of being sucked through.

Description

Aquaculture Farm sludge Remover in Fish Farm Breeding Tank

Primarily removing debris from breeding tanks, the root cause of water pollution in fish farms;

1) Improvement of water quality in the breeding tank and improvement of circulating filtration

2) Reduced water conservation and water pollution

3) Fuel cost reduction, labor cost reduction, etc.

The present invention relates to a garbage filtering device in a fish farm breeding tank, more specifically, the feed residues and excreta of the fish farmed in the fish farm breeding tank are constantly discharged, thereby generating a deadly toxic gas and the organisms in which these toxic gases are farmed. It is one of the devices for supplementing and reinforcing the filtration and purification facilities in fish farms.

However, conventionally used to remove the residue in the fish farm breeding tank conventionally used as a separate arrangement, as shown in Figure 1 (a) in a uniform multiple arrangements, fish farms in which a plurality of breeding tank 120 is installed , The tailings discharge pipe 10 having an inlet 20 and an outlet 30 to discharge the tailings (S) deposited on the bottom of the breeding tank 120 at the bottom of each breeding tank 120 in a '┘└' shape The manhole 40 is formed in the shape of a bent, close, symmetrical shape, and receives the discharged water discharged to the discharge pipe 10,

Such a configuration is shown in (b) as a plurality of fish farms breeding tank 120 is installed, each manhole 40 is connected to the drainage line 50 having a considerable length and through the filter facility 60 skimmer ( 70) and the biological filtration tank (80), oxygen supply facility (90), sterilization (100) after the process of filtering and purifying the discharge water containing the residue (S), the purified water through the water supply line (110) Each breeding tank 120 is to refill the configuration, and the way to remove the residue.

Therefore, as described above, the debris removal device of the conventional fish farm is to discharge the debris deposited on the bottom of the bottom of the center of the breeding tank with the discharged water as time passes, the fishing net (N) installed in close contact with the inlet 20 is narrowed or blocked. (If the size of the fishing net is large, the fry are sucked in.) As a result, the discharge pressure is weak and the residue remains at the bottom of the tank, so it was difficult to expect the purification ability. There is a constant inconvenience of having to move the place to drain the water and go into the breeding tank to clean it periodically.

In addition, when the discharge water is collected into the manhole 40 through the drain line 50 having a considerable length, when the discharge is attached or settled to the drain line 50, the drainage flow is blocked. Because it is buried underground and complicated, it is difficult to clean, which leads to an increase in facility cost due to the installation of a separate cleaning device.There are water pollution and cost increase in frequent breeding or cleaning in breeding tanks. The water temperature must be adjusted accordingly, resulting in excessive waste of fuel costs.

Therefore, the present invention improves the filtration capacity of fish farms by first removing the debris from the breeding tanks in the breeding tanks, and reduces the load on the purification facility, and also prevents the occurrence of deadly toxic gas in the breeding tanks. It is intended to contribute to improving the food intake rate and growth rate of the organisms at the same time, and to easily manage the management outside the breeding tank.

As a specific means of the present invention for achieving the above object;

In the process of discharging the water in the breeding tank and discharging it into the circulating water, the filtering net is preferably seated on the upper part of the discharge pipe in the filtration device case, fastened with a butterfly nut, and can be replaced at any time. The filter case and two absorption pipes connected to the filter case in the bottom bottom of the breeding tank center and the discharge pipes connected to the drainage line on the other side are preferably made of a light, easy-to-clean, anti-rust material. The absorption and discharge pipes are fixed when the filter case is connected and mounted. When the filtration device is installed at a height that corresponds to the surface of the breeding tank, the buoyancy of the water and the weight of the filtration device are fixed and connected to the discharge pipe and fixed with only minimal support.

Figure 2 (a) is a schematic diagram showing the structure and operation state of the fish farm breeding tank tailings removal device according to the present invention

(B) is enlarged part A

Looking at its configuration;

The two absorption pipes 22 lowered to the bottom of the breeding tank are connected to the bottom left of the present invention filter case 21, and the discharge pipe 23 is connected to the drain line 50 at the bottom right and connected to the drainage line 50. The filter net 24 seated inside the upper part of the case 21 is configured by being mounted and formed at an angle of 15 ° to the right when viewed from the front of FIG.

As a principle of operation, the present device is installed to be submerged in water at a height of 5 mm in the breeding tank 120 so that the breeding tank water is increased by the power of the water supplied in one direction in the breeding tank from the water supply line 110 and the oxygen supply air amount. Or, as it rotates, the scum S is collected at the center bottom by centrifugal force and the scum S is sucked into the absorption pipe inlet 221 and passed through the absorption pipe 22 to the absorption pipe outlet 222 and then the scum. Is accumulated in the inclined filtration net 24, the discharge water passing through the filtration net is sent to the filtration facility through the discharge pipe inlet 223. This is because the breeding tank is installed higher than the discharge line, and it is operated without power due to the water pressure and the water level difference.

Therefore, the debris removal device in the breeding tank according to the present invention is simple to install and operates by the water pressure and water level difference, so there is no breakdown, and because it first filters in the breeding tank where the organism grows, it improves the water quality of the fish farm along with other filtering facilities. By improving and reducing the frequency of frequent changes, it will have a great effect on the operation of fish farms such as fuel cost and labor cost saving, water saving and water pollution prevention.
