Description

Technical Field

[0001] The utility model relates to a filter cylinder for a temporary aquaculture pond with a foam separation function, belonging to the technical field of traction chairs. Background Art

[0002] The filter tank of the temporary aquaculture pond is a device used to improve the water quality. It removes waste and harmful substances through filtration and biodegradation. The filter tank generally uses different types of filter media to purify the water. For example, the Chinese utility patent with the prior art publication number CN206118851U discloses "a water filter tank for temporary aquaculture ponds for marine fish". The filter tank uses multiple levels of different filter materials to circulate and filter the water in the temporary aquaculture pond to achieve the purpose of purifying the water quality. Although the filter tank can play a purifying role, a large amount of bubbles will be generated when the water in the temporary aquaculture pond enters the filter tank, and a large amount of suspended matter will be brought out in the process of generating bubbles. The above-mentioned prior art does not process the bubbles first, which will cause pollutants to accumulate at the water inlet on the one hand, and on the other hand, they will be filtered out by the filter medium during circulation, which increases the load borne by the filter medium.

DETAILED DESCRIPTION

[0019] Combine the following Figure 1-3 The utility model is further described, but the protection scope of the utility model is not limited to the described contents.

[0020] Example 1

[0021] Reference Figure 1-3A filter cylinder for a temporary aquaculture pond with a foam separation function comprises a cylinder body 1, a partition 2 divides the cylinder body 1 into an inlet chamber 3, a first purification chamber 4, a second purification chamber 5 and a water outlet chamber 6, a plurality of filter rods 20 are arranged in the first purification chamber 4 and the second purification chamber 5, the top of the inlet chamber 3 is connected to a first cover plate 7, a water return port 8 is opened in the middle of the first cover plate 7, the top of the water outlet chamber 6 is connected to a second cover plate 9, the left side wall of the cylinder body 1 is connected to a water outlet joint 10, characterized in that the inside of the water inlet chamber 3 is connected to a baffle plate 11, a water groove 12 is opened at the lower part of the baffle plate 11, a bubble outlet groove 13 is opened on the rear wall of the water inlet chamber 3, and the bubble outlet groove 13 is a long strip groove.

[0022] The partition 2 includes a first partition 14, a second partition 15 and a third partition 16. A first water flow mechanism 17 is opened on the top of the first partition 14, and the first water flow mechanism 17 is a square hole. A second water flow mechanism 18 is opened on the bottom of the second partition 15, and the second water flow mechanism 18 is a rectangular hole. A third water flow mechanism 19 is opened in the middle of the third partition 16, and the third water flow mechanism 19 is a plurality of long strip holes.

[0023] During circulation filtration, the water in the temporary holding tank enters the water inlet chamber 3 from the return water port 8, and the generated bubbles will be blocked in front of the baffle 11. When the liquid level reaches the bubble outlet groove 13, the bubbles will flow out of the bubble outlet groove 13 along with the water, thereby taking out some pollutants and reducing the load that the subsequent filtering mechanism needs to bear.

[0024] The water after passing through the baffle 11 passes through the first purification chamber 4 and the second purification chamber 5, and is purified by the filter rod 20 to remove pollutants in the circulating water, and then passes through the water outlet chamber 6 and flows back to the temporary holding tank through the water outlet joint 10.

[0025] The filter rod 20 may use biological filter material, and by providing a filter material carrier, microorganisms are allowed to grow in the filter rod, thereby achieving the purpose of removing organic pollutants in the water through the microorganisms.

[0026] Example 2

[0027] In order to prevent fish scales from entering the first purification chamber 4 and the second purification chamber 5 , a fish scale collecting net 21 is connected to the lower part of the first cover plate 7 , and the fish scale collecting net 21 is directly below the water return port 8 .

[0028] This prevents fish scales from entering the filter tank, thus avoiding clogging of the filter medium.

[0029] Although the technical solutions of the present invention have been described and listed in detail, it should be understood that it is obvious to those skilled in the art to make modifications to the above-mentioned embodiments or adopt equivalent alternatives. These modifications or improvements made without departing from the spirit of the present invention are within the scope of protection required by the present invention.
