Abstract

The utility model discloses a dry-type air filter of a heavy-duty car, wherein a connecting disk (3) is connected with a strengthening lining board (2) which is fixedly connected with the upper end surface of an inner cavity of an upper shell, thread in an air outlet of the connecting disk (3) is matched and connected with the upper end portion of a filter element (4), and the lower end portion of the filter element (4) is embedded and connected with a ring sleeve of a reverse torque flow disk (7) of the inner cavity of a lower shell. The reverse torque flow disk (7) is connected with an outer ring upper end surface of the filter element (4), and at least a dust inlet (10) is arranged. The dust inlet (10) is communicated with the inner cavity of a dust collection shell (8), which is connected with the lower end surface of the reverse torque flow disk (7), and the lower end of the inner cavity of the dust collection shell is communicated with a water drain pipe (9) which is connected with the lower shell. Compared with the prior art, the dry-type air filter of the heavy-duty car effectively prolongs the maintenance period of the filter element, obviously increases the filtering quality of engine air, and conveniently and rapidly maintain, dismantle and mount the filter element.

Description

The heavy-duty car dry-type air cleaner

(1) technical field:

The utility model relates to the automobile air filter; Be specifically related to a kind of heavy-duty car dry-type air cleaner.

(2) background technique:

Heavy-duty car air-strainer of the prior art, its structure are normally by upper and lower casing and place cyclone cover that its inner chamber ring set joins and filter core to be connected by bolt, nut to constitute.It exists not enough: the one, when heavy-duty car is worked under the rugged environment that dust impurity flies upward, though enter the air that contains dust impurity in the filter cleaner through filter element filtering by cyclone cover, but be difficult to from the dust flue of filter case bottom, in time discharge, be trapped in the dust impurity of circulation rotation in the housing inner chamber, very easily cause the early stage obstruction of filter core, shortened the maintenance cycle of filter core, dust impurity on the untimely slightly removing filter core of staff has then reduced the filter quality of engine air; The 2nd, early stage filter core that stops up such as need are removed the dust impurity on it, and the filter core that connects by bolt, nut removes and installs very inconvenient, have reduced the working efficiency of maintaining.

(3) summary of the invention:

At the deficiency that above-mentioned prior art exists, the utility model provides a kind of maintenance cycle that prolongs filter core, improves the filter quality of engine air, and removes and installs heavy-duty car dry-type air cleaner easily.

For achieving the above object, the technological scheme of the utility model heavy-duty car dry-type air cleaner is achieved in that cyclone cover and the filter core that mainly comprises upper and lower casing and place its inner chamber ring set to join; On the reinforcement liner plate that described upper shell inner chamber upper-end surface is connected, be connected with land; In the air outlet hole of described land, screw-thread fit is connected with the upper end portion of filter core; Described filter core underpart is inlayed with the reverse eddy flow tray ring set that places lower housing cavity and to be joined; Be connected with the outer shroud upper-end surface of filter core on the described reverse eddy flow tray, be provided with an entering-dust mouth at least; Described entering-dust mouth is communicated with the dust collection shell inner chamber that is connected in reverse eddy flow tray lower end surface; Described dust collection shell inner chamber lower end is communicated with dust flue on being connected in lower shell body.

The utility model is provided with entering-dust mouth by the outer shroud upper-end surface of taking to be connected with filter core at above-mentioned reverse eddy flow tray, during work, make enter the housing inner chamber treat air filtering produces relative entering-dust mouth by cyclone cover rotating flow to, make filter element filtering viscous flow in time enter the dust collection shell inner chamber, discharge by dust flue at the dust impurity of housing inner chamber.Compare with prior art, prolonged the maintenance cycle of filter core effectively, improved the filter quality of engine air significantly.Filter core upper end is by joining with land air outlet hole screw thread, and the lower end is inlayed with reverse eddy flow tray ring set and linked to each other, and has realized removing and installing convenient and swift, has improved the working efficiency of filter core maintaining effectively.

Fig. 1 is first kind of mode of execution part section of the utility model plan view;

Fig. 2 be among Fig. 1 A-A to sectional view;

Fig. 3 be among Fig. 2 B-B to sectional view;

Fig. 4 is a C place part section zoomed-in view among Fig. 1;

Fig. 5 is second kind of mode of execution part section of the utility model plan view.

(5) embodiment:

Fig. 1-shown in Figure 5.This heavy-duty car dry-type air cleaner, the cyclone cover and the filter core that mainly comprise upper and lower casing and place its inner chamber ring set to join constitute; On the reinforcement liner plate 2 that described upper shell inner chamber upper-end surface is connected, be connected with land 3; In the air outlet hole of described land 3, screw-thread fit is connected with the upper end portion of filter core 4; Described filter core 4 underparts are inlayed with reverse eddy flow tray 7 ring sets that place lower housing cavity and to be joined; Be connected with the outer shroud upper-end surface of filter core 4 on the described reverse eddy flow tray 7, be provided with 12 entering-dust mouths 10; Described entering-dust mouth 10 is communicated with dust collection shell 8 inner chambers that are connected in reverse eddy flow tray 7 lower end surfaces; Described dust collection shell inner chamber lower end is communicated with dust flue 9 on being connected in lower shell body.Described dust collection shell 8 inner chambers are cone shape (Fig. 1, shown in Figure 5).During work, treat that air filtering enters the housing inner chamber by inlet hole 5, the rotating flow that produces through cyclone cover 6 to, enter in the motor through air outlet hole 1 by filter core 4 filtered airs and to work.At this moment, the dust impurity that the housing inner chamber is detained through filter element filtering, under the effect of housing inner chamber rotational flow air, the dust exhaust port 10 that is provided with by reverse eddy flow tray 7 enters the conical cavity of dust collection shell 8, at intracavity bottom, discharge (shown in Figure 1) automatically along its inclined-plane landing by dust flue 9.The utility model can adopt the linkage structure of vertical installation (shown in Figure 1) or horizontal installation (shown in Figure 5) according to the different mounting point of heavy-duty car.

The above only is a preferred implementation of the present utility model.Be noted that for the person of ordinary skill of the art; under the prerequisite that does not break away from the principle of the invention; need not other technical characteristics that the process creative work just can be associated; can also make some modification and/or improvement; these variations obviously all should be considered as equivalent feature, all belong within the protection domain of the utility model patent.
