Description

Technical Field

[0001] The utility model relates to the technical field of breeding equipment, in particular to a high-efficiency perch breeding filtering equipment. Background Art

[0002] Seabass is one of the four famous freshwater fishes in my country. It has white, tender meat and delicious taste. It is rich in unsaturated fatty acids, protein, vitamins, calcium, magnesium, zinc, selenium and other nutrients, and has a good tonic effect. When breeding seabass, high requirements are placed on water quality, and the water needs to be kept fresh and fluid. In actual applications, filtering equipment is often used to filter fish feces, sludge, leaves and other debris in the fish pond, so as to ensure the fluidity of the water while ensuring the cleanliness of the breeding water.

[0003] In the prior art, the filtering equipment used for sea bass farming mostly filters the flowing wastewater through a filter screen. In order to achieve a better filtering effect, a filter screen with a finer pore size is often used. The finer filter screen will also cause greater resistance when the wastewater passes through, and low-speed water cannot pass through well, resulting in poor filtering effect. In addition, the existing filtering device cannot achieve the discharge of debris well. After the debris accumulates to a certain amount, the device needs to be opened for removal, which makes the device inconvenient to use. For this reason, we propose a high-efficiency sea bass farming filtering equipment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a high-efficiency seabass breeding and filtering equipment, which has a high-efficiency filtering unit and can make the breeding wastewater in the water storage cylinder in an active state by stirring and turning over, and keep the properties of each part uniform to ensure a good filtering effect. The water in the rotating state obtains impulse, and when it contacts the fine mesh membrane near the side wall, fine debris such as fish feces in the wastewater will be isolated outside, and the clean water will enter the water collection pipe mouth and further flow into the annular water tank under the action of centrifugal force, so as to achieve high-efficiency filtration of breeding wastewater. The utility model also has an impurity discharge unit, and the PLC controller controls the intermittent rotation operation of the motor and the waterproof motor, so as to realize the cyclic switching of the equipment between the filtering and sewage discharge states, so as to ensure that the breeding wastewater in the fish pond can be filtered stably for a long time, and can effectively solve the problems in the background technology.

[0009] The water inlet flange is used for the introduction of sea bass breeding wastewater. The pool water is introduced into the water storage cylinder from the upper side. The installation sleeve is used for the insertion at the bottom of the middle rotating shaft, and the middle rotating shaft can rotate. Driven by the upper motor, the middle rotating shaft drives the flip plate and the impeller to rotate. The impeller stirs the water in the water storage cylinder to rotate horizontally. The inclined flip plate at the bottom can flip the bottom water upward, so that the breeding wastewater entering the water storage cylinder can be in an active state, keeping the properties of each part uniform to ensure a good filtering effect. The water in the rotating state gains impulse. When it contacts the fine mesh membrane near the side wall, fine debris such as fish feces in the wastewater will be isolated from the outside, and the clean water will enter the water collection pipe mouth and further flow into the annular water tank under the action of centrifugal force, thereby realizing efficient filtration of breeding wastewater. The impurity discharge unit is used to discharge the filtered debris.

[0010] Furthermore, the high-efficiency filtration unit also includes a shaft sleeve, a connecting rod and a motor. The shaft sleeve is rotatably connected to the outer side of the circle at the upper position of the middle rotating shaft. The shaft sleeve is fixedly connected to the inner wall of the water storage cylinder through three connecting rods in a circumferential array.

[0011] Furthermore, the impurity discharge unit comprises a bottom plate, a movable stopper, a waterproof motor and a liquid level sensor. The bottom of the water storage cylinder is composed of three fan-shaped bottom plates, which are arranged in a circular array around the installation sleeve.

The hollow structure inside the bottom plate can contain the movable stopper, and the waterproof motor can drive the movable stopper to rotate into the bottom plate. When the liquid level sensor detects that the water level in the water storage cylinder is lower than the height of the sensor, the PLC controller controls the waterproof motor to energize and drive the movable stopper to rotate into the bottom plate. At this time, the bottom of the water storage cylinder is opened, and the remaining water in the water storage cylinder rolls the filtered debris into the sewage channel on the lower side in a rotating state.

[0012] Furthermore, the impurity discharge unit also includes a PLC controller and a sewage channel. The bottom of the installation box is provided with a sewage channel facing backwards.

[0014] Furthermore, it also includes a filter box and a filter screen. The pipe of the water inlet flange is connected to the upper side of the water storage cylinder inwardly. The filter box is installed at a section of the pipe outside the installation box. The filter screen is inserted from the upper side of the filter box, and a sealing component is provided at the end of the filter screen.
