Abstract

The invention relates to a primary filtering device for sewage treatment. The primary filtering device effectively overcomes the problem of inconvenience of cleaning and great consumption of time andlabor during primary filtering of sewage. According to a technical scheme in the invention, the primary filtering device comprises a cylinder; an annular sleeve is arranged in the cylinder and provided with blind holes; the cylinder is provided with a snapping groove; each blind hole is internally provided with a wedge block, and the non-bevel end of the wedge block is connected with the bottom ofthe blind hole by a first pressure spring; a sleeve is arranged above the annular sleeve; a filter net is installed in the annular sleeve and is rotatably connected with a threaded rod; the upper endof the threaded rod has an arc-shaped scraping plate; the lower end of the threaded rod is connected with a ratchet via threads; the threaded rod and the ratchet cannot realize self-locking; the outer part of the ratchet is provided with a pawl matched with the ratchet; and the part, located between the ratchet and the filter net, of the threaded rod is provided with a second pressure spring which allows the threaded rod to reset upwards. The primary filtering device of the invention is novel in concept, ingenious in structure and good in practicability.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a primary filter device for sewage treatment. Background technique [0002] With the development of social urbanization, science and technology, and humanization, the industrial industry has developed vigorously, and more and more factories have sprung up, followed by the increase in the use of environmental protection equipment and the problem of sewage pollution. It is obvious that sewage contains industrial production materials, intermediate products and products lost with chemicals, and pollutants produced in the production process. With the rapid development of industry, the types and quantities of sewage have increased rapidly, and the pollution of sewage has become increasingly widespread and serious. , threaten human health and safety. Therefore, for the protection of the environment, the treatment of sewage is more important than the treatment of urban sewage ch...
