Abstract
The utility model provides an enhanced pre-filter device of an air filter assembly. The enhanced pre-filter device comprises a barrel with an upper opening, the barrel is divided into three chambers via an upper partition and a lower partition which are arranged in the barrel, a plurality of swirl tubes are mounted between the upper partition and the lower partition side by side, upper ends of the swirl tubes are communicated with the upper opening, lower ends of the swirl tubes are communicated with the chamber between the upper partition and the lower partition, a dust discharge outlet is arranged at the bottom of the chamber, the bottom surface of the lower partition is inclined towards the dust discharge outlet, a radial air outlet tube is arranged on the barrel below the lower partition, a dust discharge tube is arranged at the bottom of the barrel, and the upper opening of the barrel is served as an air inlet. As the air outlet tube of the pre-filter is directly connected with an air inlet tube of the air filter assembly, dust and other impurities in air can be separated secondarily effectively and rough filtration effect is increased greatly; and most of dust in air is filtered by aid of the swirl tubes, thereby achieving filtration efficiency over 90%.
Description
Technical field
The utility model relates to the pre-filter device of the enhancement mode that is connected the air cleaner assy air intake duct.
Background technology
In the empty filter course of work, air is through air inlet pipe, only depends on the coarse filtration filter effect of blade ring of sky filter often very limited, also will strengthen the maintenance frequency of filter core simultaneously, so need when air enters sky filter body, filter in advance, to alleviate the work load of empty filter body.
Summary of the invention
In order to guarantee that airborne most of dust is filtered before air cleaner assy, the utility model proposes the pre-filter device of enhancement mode of air cleaner assy.
For this reason, the technical solution of the utility model is: the pre-filter device of the enhancement mode of air cleaner assy, comprise uncovered cylindrical shell, it is characterized in that: be provided with upper spacer, lower clapboard in the cylindrical shell, upper spacer, lower clapboard are divided into three chambers to cylindrical shell, and a plurality of cyclone pipes are installed between upper spacer, the lower clapboard side by side, cyclone pipe upper end and last uncovered the connection, the cyclone pipe lower end is communicated with cavity between upper spacer, the lower clapboard, and the bottom of this cavity is provided with ash discharging hole, and the bottom surface of lower clapboard tilts to ash discharging hole; Cylindrical shell under the lower clapboard is provided with radially escape pipe, and the cylindrical shell bottom is provided with ash releasing tube, and the last uncovered of cylindrical shell is air inlet.
Beneficial effect: the utility model directly is connected with air inlet pipe in air cleaner assy by its escape pipe, centrifugal rotation centrifugation and gravity effect by air movement track and cyclone pipe, dust in air and other impurity etc. can be carried out twice effectively separates, improve macrofiltration greatly, lower clapboard is the assembling of tilting, can guide the dust that separates for the first time into ash discharging hole, the design of storm wind pre-flock bottom of device is similarly tilts to draw grey structure, and the dust that separates is for the second time drawn; Airborne most of dust can be filtered by cyclone pipe, filter efficiency reaches more than 90%.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
As shown in Figure 1, it is as follows to further describe the utility model: the pre-filter device of the enhancement mode of air cleaner assy, comprise uncovered cylindrical shell 1, be provided with upper spacer 2, lower clapboard 5 in the cylindrical shell 1, upper spacer 2, lower clapboard 5 are divided into three chambers to cylindrical shell, a plurality of cyclone pipes 6 are installed between upper spacer 2, the lower clapboard 5 side by side, cyclone pipe 6 upper ends and last uncovered the connection, cyclone pipe 6 lower ends are communicated with cavity between upper spacer 2, the lower clapboard 5, the bottom of this cavity is provided with ash discharging hole 3, and the bottom surface of lower clapboard 5 tilts to ash discharging hole 3; Cylindrical shell under the lower clapboard is provided with radially escape pipe 4, and the cylindrical shell bottom is provided with ash releasing tube 4, and the last uncovered of cylindrical shell 1 is air inlet.
