Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dry filter cloth air cleaner device mainly used in industrial vehicles.

In a conventional air cleaner device of this type, a filter paper serving as an air cleaner element is arranged and fixed between an outer cleaner body and a discharge duct in the center, and dust-containing air sucked in from an inlet passes through small holes in the filter paper 3. The structure was such that it was filtered, purified, and sent to the engine.

These conventional air cleaner devices used filter paper as the air cleaner element, which required cleaning of the element every 10 to 40 hours, and the element had to be replaced with a new one every 500 hours. The drawback was that it had a short lifespan.

In view of the above-mentioned conventional drawbacks, the present invention provides a dry filter cloth air cleaner device that uses a filter cloth instead of the conventional filter paper to extend the life of the air cleaner element and to simplify the entire device. That is.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing an embodiment of the present invention, and reference numeral 10 in the figure is a cleaner main body, and a collar member 11 and a packing 1 are provided at the right end of the main body 10.
2 to the discharge duct 13, the plate member 14, and the filter cloth 1.
The right end of 5 is fixed with a plurality of bolts 16. Eight linear filter cloth guides 17 (see FIG. 3) are installed on the inner circumference of the filter cloth 15, and the cylindrical shape of the filter cloth 15 is maintained by these guides 17.

An air intake port 18 (see FIG. 2) having a rectangular cross section is formed in the cleaner body 10, and two ring supports 19 are disposed inside the main body 10 near this intake port 18. Hooks 21 for locking two rings 20 are pivotally attached to these supports 19 via pins 22. When the ring 20 moves in the front, back, left and right directions due to vehicle body vibration and comes into contact with the filter cloth 15, the dust attached thereto is removed.

A service cap 23 is removably installed at the other end of the cleaner main body 10 (the left end in FIG. 1) with a catch 24, and a filter cloth 1 A barrier plate 25 having an axially long shape is provided on the lower side of the
is fixed to the main body 10.

In this configuration, when the engine is started, air is drawn into the air intake port 1 by the suction force of the engine.
When inhaled from 8 to a arrow (Figure 2),
Since the structure is such that air enters in the circumferential direction, the intake air is filtered by the filter cloth 15 while going around the outer circumference of the filter cloth 15 in the direction of arrow b, and the purified air is passed through the engine. Direction (direction c in Figure 1)
sent to. On the other hand, the dust that enters from the intake port 18 together with the air is ultimately prevented from advancing by the barrier plate 25 below the filter cloth 15, and accumulates as shown in FIG.

Note that this air cleaner device does not cause clogging even when used for a long time because the ring 20 comes into contact with the filter cloth due to the vibration of the vehicle body and brushes off the dust on the surface of the filter cloth. It is also possible to insert the tip of a certain bar 26 through the intake port 18, hook the hook portion to the aforementioned hook 21, and move the bar 26 back and forth in the axial direction to brush off dust. Further, by releasing the catch 24 and opening the service cap 23, dust accumulated on the barrier plate 25 can be removed.

As described above, the present invention includes a cleaner body in which an air intake port is formed on the outer periphery so that air can be taken in in the circumferential direction, and a filter cloth guide provided inside the cleaner body and held by a plurality of filter cloth guides. a cylindrical filter cloth; a discharge duct fixed together with one end of the filter cloth and the cleaner body via a fixing member;
one or more rings pivotally attached to the inner periphery of the cleaner main body in proximity to the outer periphery of the other end or center of the filter cloth; and a barrier plate fixed to the lower inner periphery of the cleaner main body; Since the service cap is attached to the end of the cleaner body on the other end of the filter cloth so as to be openable and closable, dust adhering to the vicinity of the filter cloth can be automatically brushed off by vibrations when the vehicle is running. . Furthermore, if the filter cloth becomes clogged, it can be removed and cleaned or washed for reuse, thereby extending the life of the filter cloth.

Furthermore, the structure is simpler than the conventional one and can be manufactured at low cost.
