Description

Technical Field

[0001] The utility model relates to the technical field of firefly breeding, in particular to an aquatic firefly larva breeding box with a backwashing function. Background Art

[0002] When artificially raising aquatic fireflies, since the excrement and other impurities generated during the growth process of aquatic fireflies will pollute the water in the breeding box, the water used for breeding fireflies needs to be replaced manually regularly. Due to the fact that manual water replacement is not timely, it is easy to cause the death of fireflies. Therefore, it is necessary to filter the water inside the breeding box. However, most of the existing breeding box filtering devices do not have a backwashing function. After filtering the water in the breeding box for a long time, the filter media is prone to blockage, affecting the filtering effect, thereby leading to a deterioration of the growth environment of aquatic fireflies.

[0011] The beneficial effects of the present utility model are as follows:

[0012] A breeding box for aquatic firefly larvae with a backwashing function according to the present utility model continuously filters the water in the breeding box through a water pump, a connecting water pipe, a filter layer and a water outlet pipe. Through a sewage pipe, after the filtering effect of the filter layer decreases, the filter media is backwashed to discharge the sundries in the filter media. Through a water inlet pipe and a float valve, the breeding box is replenished with water to maintain a good breeding environment for aquatic fireflies. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following further describes the specific embodiments of the present utility model with reference to the drawings. The same components are denoted by the same reference numerals.

[0018] It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0019] In order to make the content of the present utility model more clearly understood, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

[0020] As Figures 1 to 2 shown, a breeding box for aquatic firefly larvae with a backwashing function includes a box body 1. The box body 1 is filled with breeding water. A partition board 2 is provided inside the box body 1. A breeding net 12 is provided above the partition board 2. Aquatic firefly larvae are bred on the breeding net 12.

[0021] A water pump 8 is installed on the outer side of the box body 1. The water inlet end and the water outlet end of the water pump 8 are respectively communicated with a connecting water pipe 7. A supporting layer 5 is arranged below the partition plate 2, and a filtering layer 6 is arranged above the supporting layer 5. The filtering layer 6 is provided with activated carbon and quartz sand fillers. The box body 1 is provided with a connecting water pipe 7. One end of the connecting water pipe 7 extends above the partition plate 2 and the other end passes through the filtering layer 6 and extends above the filtering layer 6. An outlet water pipe 13 is arranged between the supporting layer 5 and the partition plate 2. One end of the outlet water pipe 13 extends above the partition plate 2 and the other end extends below the supporting layer 5.

[0022] During the breeding process of aquatic firefly larvae, the water pump 8 pumps sewage from the box body 1, and pumps the sewage to above the filtering layer 6 through the connecting water pipe 7. The filtering layer 6 filters the sewage, and the filtered water flows into above the partition plate 2 through the outlet water pipe 13 again.

[0023] A sewage discharge pipe 9 is arranged at the top of the partition plate 2. An automatic exhaust valve 11 is arranged at the top of the sewage discharge pipe 9. A sewage discharge pool 10 is arranged on the outer side of the box body 1. One end of the sewage discharge pipe 9 away from the partition plate 2 extends into the sewage discharge pool 10. When the filtering effect of the filter material in the filtering layer 6 becomes poor, the water level in the sewage discharge pipe 9 rises. When the water level in the sewage discharge pipe 9 rises to the highest point and then starts to drop, siphonage is generated, and the water in the box body 1 flows back from the drain pipe 13 to backwash the filter material. When the water level in the box body 1 is lower than the height of the drain pipe 13, the backwashing stops, so that the filter material always maintains a good filtering effect.

[0024] A water inlet pipe 3 is arranged at the top of the outer side of the box body 1. The water inlet pipe 3 is connected to the breeding tap water source. A float valve 4 is connected to the water inlet pipe 3. After the water level in the box body 1 drops, the float valve 4 opens to replenish water for the box body 1 to maintain a good breeding environment for aquatic fireflies.

[0025] The above is only a preferred embodiment of the utility model patent, and it is not intended to limit the utility model patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model patent shall be included in the protection scope of the utility model patent.
