Technical Field
[0001] This utility model relates to the field of crocodile farming technology, specifically to a wastewater treatment device for crocodile farms. Background Technology
[0002] Crocodiles are rare aquatic wild animals found worldwide. They are one of the amphibian species that lived 65 million years ago during the ancient dinosaur era. They are distributed in Africa, South America, and a few tropical rainforest regions in Asia. Artificial breeding is an effective measure that integrates conservation and economic benefits for humankind, protecting endangered species while creating economic benefits for humans. The main crocodile species raised in captivity include saltwater crocodiles, Nile crocodiles, and Siamese crocodiles. These species are widely chosen because of their strong adaptability, fast growth rate, and high economic value.
[0003] Existing patent CN220003184U discloses a wastewater treatment device for crocodile farms, including a tank. A water suction device and a lifting device are provided on one side of the tank. A filter device is installed inside the tank. The water suction device includes a water suction pipe and a water suction ball. The water suction ball is fixedly installed at the bottom of the water suction pipe, and several water suction holes are provided along the spherical surface of the water suction ball.

Then, the water pump 61 is started, which draws the sewage into the tank 1 through the suction head 65. Impurities are filtered out through the filter screen 13 inside the tank 1. The overflow pipe 11 allows observation of whether sewage overflows. If overflow occurs, it indicates that the filter screen 13 is blocked. The water pump 61 is then turned off, allowing all the sewage in the tank 1 to be discharged. Then, the push plate 47 is pushed, which causes the locking rod 48 to disengage from the locking groove 49. Then, the sealing plate 42 is removed, and the first motor 22 is started. The first motor 22 can... The first screw 23 is rotated, which in turn drives the drive frame 24 to move, which in turn drives the unblocking brush 25 to move. The unblocking brush 25 can clean the impurities on the top of the filter screen 13. The impurities are discharged through the drain port 26 and fall into the collection box 34. The collection box 34 can collect the impurities. After cleaning, the push plate 47 is pushed again and the sealing plate 42 is inserted into the drain port 26. The spring 46 returns to its original position and drives the locking rod 48 to lock into the locking groove 49, which can fix the sealing plate 42 to the tank 1. Then the water pump 61 is started again to treat the sewage again. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
