Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a sinking drum filter which is easy to install. Background Art

[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] When constructing water filtration in the aquaculture industry, it is necessary to build a filter pool with a rotary drum filter installed. The water in the fish pond is filtered through the rotary drum filter. In the prior art, the mounting frame of the rotary drum filter is fixed. When facing filter pools of different depths, it does not have a height adjustment function. It can only be customized according to the size of the filter pool or replaced with different mounting frames for installation, which makes it poor in applicability and also brings inconvenience to the debugging during installation. Therefore, there is room for improvement. Utility Model Content
