[0002] Aquaculture is a production business that uses suitable waters to breed aquatic economic animals and plants. Fisheries are an important part of it. Aquaculture can be divided into freshwater aquaculture, seawater aquaculture, and shallow sea flat aquaculture. China is one of the earliest countries in the world to develop freshwater fish farming. In long-term production practice, people have accumulated rich experience and technology in fish farming. To raise fish, you must first raise water. Water is the environment for fish to survive. Better water quality can reduce the occurrence of fish diseases and is more conducive to the growth and survival of fish. In freshwater aquaculture, the fish pond needs to be treated regularly to improve the water quality of the fish pond. For this purpose, a rotary drum filter is required.

[0003] In the prior art, the rotary drum filter is installed in a mounting frame, and the filter drum is rotated by a motor to send water to be filtered into the filter drum. As the filter drum rotates, the filter cloth arranged on the surface of the filter drum filters the water. However, the filter cloth in the existing equipment is fixed in the filter drum as a whole. When a part of the filter cloth is damaged during use, the whole filter cloth must be replaced in order to ensure the filtering effect, which brings inconvenience to loading and unloading and also causes waste of resources. Therefore, there is room for improvement. Utility Model Content
