Impurity collecting and discharging device

Abstract

The present invention discloses an impurity collecting and discharging device which is used in a cyclone pipe type fluid pre-filter. A middle part of a fluid pre-filter shell body is vertically provided with a fluid discharge pipe along an axis direction; a cyclone pipe is arranged between the outer wall of the fluid pre-filter shell body and a fluid discharge pipe; the lower part of the cyclone pipe is provided with an impurity collecting device; an inner annular opening of the impurity collecting device communicates with the fluid discharge pipe; an impurity collecting box with an opening upward; a plurality of impurity-receiving chambers are divided by setting a plurality of vertical partition plates in the impurity collecting box; the impurity collecting box is made from a transparentmaterial; the lower part of the impurity collecting box is provided with an impurity automatic discharging device; the impurity automatic discharging device comprises a plurality of impurity discharging ports and impurity guiding grooves; the number of the impurity discharging ports is the same as the number of the impurity-receiving chambers; and besides, the arranging position of each impurity discharging port corresponds to the position of each impurity-receiving chamber. The provided impurity collecting and discharging device can avoid problems that impurities of separating devices are notdischarged smoothly and installation is inconvenient under a premise of ensuring high-efficiency separation.

Description

[0001] technical field [0002] The invention relates to a fluid filtration and purification system, in particular to an efficient fluid impurity separation device, a swirl tube type fluid prefilter, an impurity collection device and an impurity collection and discharge device. Background technique [0003] The fluid impurity separation device widely used in construction machinery and agricultural machinery equipment in my country, its separation efficiency is restricted by technical conditions, the separation effect is not good, and the function is single. At present, this kind of fluid impurity separation device is roughly divided into three categories: basin prefilter, swirl tube prefilter and automatic dust removal prefilter. The corresponding filtration efficiencies are: basin prefilter ≥ 70%, rotary Flow tube pre-filter ≥ 80%, automatic dust-exhaust pre-filter ≥ 80%, it can be said that the separation effect of the current separation device is not good for impuritie...
