Embodiment Construction

[0011] Accompanying drawing has shown structure of the present invention and embodiment thereof, further describes the relevant details of its embodiment below in conjunction with accompanying drawing: Attached figure 1 A reflux and backwashing mechanism for automatic fluid filtration, including an upper casing 17 and a lower casing 18 installed together, the upper casing 17 has a fluid exchange chamber 2, and the fluid exchange chamber 2 has a A rotatable paddle 11, a baffle 10 and a hollow shaft sleeve 12. The paddle 11 and the baffle 10 are connected with the hollow shaft sleeve 12 as a whole, which is called a replacement fluid. The upper casing 17 includes a return outlet 15 and the tangentially arranged fluid inlet 1, because the inlet 1 is arranged tangentially, the tangential impulse of the fuel can generate the maximum torsional moment, which impacts the blade 11, and an upper partition is arranged inside the upper casing 17 and the lower casing 18 4. The upper partit...

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 p...
