Reflow backwashing mechanism for automatic filtration of fluid

Abstract

The invention discloses a reflow backwashing mechanism for automatic filtration of fluid. The reflow backwashing mechanism is characterized in that: a fluid inversion chamber (2) is internally provided with a hollow shaft sleeve (12), a blade and a baffle plate are connected with the hollow shaft sleeve (12) which is provided with an opening at a position of the lower part of the baffle plate of the hollow shaft sleeve (12), the hollow shaft sleeve (12) is internally provided with a hollow core shaft (13) with an upward opening, and a shaft wall of the hollow core shaft (13) is distributed with a through hole (14). The reflow backwashing mechanism is provided with a guide through hole with obliquity, thus being capable of fully utilizing composite force of reflow backwashing produced by normal fluid flow and fluid flow out of the oblique guide through hole to quicken rotation frequency of the inversed fluid. The inversed fluid is more stable due to dependence on the core shaft for rotation and arrangement of a counterweight balance, thus the reflow backwashing mechanism has advantages of causing the whole system to have safe and reliable operation and greatly improving automatic filtration effect.

Description

technical field [0001] The invention relates to a backwashing structure of an automatic fluid filter circuit, such as an automatic filter circuit backwash purification of air and water, and in particular to a circuit backwash automatic filter mechanism for vehicle and ship power air filters, machine filters, and fuel filter devices. Background technique [0002] The fluid filtration capacity of the known technology is large and wide, and they are all clogged ordinary filter devices. Since there is no backwash function, the more the filter becomes more clogged, the fluid will not pass through after a period of work, and it is necessary to stop the machine to replace or replace the filter element. The way of working has been difficult to perform the filtering tasks on modern power or machines. The traditional automatic filter with electromechanical signal to control the backwashing function is complex and expensive, making it desirable for a large number of small and medium po...

AI Technical Summary

Problems solved by technology

It basically meets the needs of automatic fuel filter for diesel engines. After years of testing and use, it is found that the original design of the commutation structure still has shortcomings, the speed of fluid replacement is not high, and the stability is not enough. sex

Because there is no mandrel to rely on for the replacement fluid to rotate, it collides with the surroundings during rotation, the friction torque is large, and the backflow and backwashing force is not used, which affects the rotation frequency of the replacement fluid and the stability of work
