The development of sewage mixers (also often referred to as submersible mixers or sewage treatment mixers in specific occasions) can be summarized as the following key stages:

First, early exploration and invention

The invention of the blender can be traced back to the early 20th century, but its original form is not directly aimed at sewage treatment. The world's first mixer was invented by American engineer Stephen J. Pope in 1908 and began selling in the United States in 1910. This invention was mainly based on the increase in demand for kitchen appliances under the background of the industrial revolution at that time, and the insufficiency of mixing equipment in practical applications.

Preliminary exploration of sewage mixer: Although the direct origin of sewage mixer is difficult to accurately trace to a specific year or inventor, it is certain that with the gradual development of sewage treatment technology, the demand for sewage mixing equipment is becoming increasingly apparent.

Second, professional development and technological innovation

The birth of sewage mixer: In the field of sewage treatment, sewage mixer as one of the key equipment, its professional development began in the middle and late 20th century. Among them, Sweden's ITT Flygt has made remarkable achievements in this field. In 1976, Feili successfully launched the world's first sewage treatment mixer, marking that the sewage treatment mixer officially entered the professional and large-scale production stage.

Technological innovation and product upgrades: Since Feili launched the first sewage treatment mixer, the technology has been continuously improved and perfected. In 1992, Feili Company launched a new generation of sewage treatment mixer, further improving the performance and quality of products. At the same time, many domestic and foreign enterprises have also invested a lot of manpower and financial resources in the research and development and production of sewage mixers, which has promoted the rapid development of the technology.

Third, market application and popularization

Market demand growth: With the acceleration of urbanization and the continuous growth of population, sewage treatment has become an important environmental protection measure in modern society. In this context, the market demand for sewage mixers continues to grow, and they are widely used in urban sewage treatment plants, industrial wastewater treatment and other fields.

Product diversification: In order to meet the requirements of different occasions and processes, sewage mixers have gradually formed a diversified product series. For example, according to the different installation methods, it can be divided into submersible mixer and vertical mixer; According to the different mixing effect, it can be divided into low speed pushing type and high speed dispersing type.

Fourth, intelligent and green development

Intelligent trend: With the rapid development of technologies such as the Internet of Things and big data, sewage mixers are gradually developing in the direction of intelligence. By integrating advanced technologies such as intelligent control systems and sensors, remote monitoring, automatic regulation and fault warning can be achieved to improve production efficiency and safety.

Green requirements: In the context of increasingly strict environmental protection policies, sewage mixers pay more attention to green requirements in the design and manufacturing process. The use of environmentally friendly materials and processes, reducing energy consumption and emissions and other measures have become an industry consensus.

In summary, the development process of sewage mixer has experienced multiple stages from early exploration and invention to professional development and technological innovation to market application and popularization as well as intelligent and green development. In the future, with the continuous progress of technology and changes in market demand, sewage mixers will continue to develop in a more efficient, smarter and more environmentally friendly direction.
