Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air cleaner provided in an industrial vehicle or the like having an air brake device.

[0002]

[Prior art]

 Conventionally, as an air cleaner of this type, there is one shown in FIG. 3, for example. That is, the element 32 is detachably mounted in the main body 31, and the element 32 is fixed by screwing the wing nut 33 into the bolt body 34 in the main body 31. A baffle 41 is detachably fitted to one end of the element 32.

An element exchange port 35 is formed at one end of the main body 31, a detachable lid 36 is attached to the element exchange port 35, and the lid 36 is clamped and fixed to the main body 31 by a clamp band 37. . Further, the main body 31 is provided with an inlet 38 opening upstream of the element 32 and an outlet 39 opening downstream of the element 32.

According to this, when cleaning the element 32, the vehicle is moved to a maintenance shop, the clamp band 37 is removed, the lid 36 is removed, the baffle 41 and the wing nut 33 are removed, and then the element is removed. 32 is taken out from the main body 31 through the element exchange port 35. Then, as shown in FIG. 4, compressed air is ejected from the tip of the hose 40 connected to the compressor installed in the maintenance plant, and the compressed air is caused to flow from the downstream side to the upstream side of the element 32. The dust 42 adhering to the element 32 was blown off.

[0005]

[Problems to be solved by the device]

 However, according to the conventional method described above, when cleaning the element 32, the element 32 must be removed and taken out of the main body 31 each time, and the vehicle must be moved to a maintenance shop with compressed air supply equipment. It had to be done, so it was very troublesome.

The present invention solves the above problems, and an object thereof is to provide an air cleaner capable of easily cleaning an element.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is an air cleaner provided in a vehicle having an air brake device, in which a removable element is provided in a main body, and the main body has an element replacement port and an upstream side of the element. An inlet opening to the element and an outlet opening to the downstream side of the element are provided, and a lid that can be opened and closed is provided at the element replacement port, and the downstream side of the element and the air tank side of the air brake device are connected by piping. A switchgear is provided in this pipe.

[0008]

[Action]

 According to the structure of the above invention, the air flowing into the main body from the inlet is removed from dust and the like when passing through the element, then flows out from the outlet and is supplied to the engine or the like.

When cleaning the element, by opening the lid and opening the opening / closing device, the compressed air in the air tank flows back from the downstream side of the element to the upstream side through the piping, and at this time, it adheres to the element. The dust that is being blown is blown off to the upstream side, and is discharged to the outside from the element replacement port together with the blown dust.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 is an air cleaner provided in an industrial vehicle (a wheel loader, a forklift, etc.) having an air-hydraulic hybrid brake device. The main body 2 of the air cleaner 1 is formed in a cylindrical shape, and the element 3 is detachably provided therein. An element exchange port 4 is formed at one end of the main body 2, an inlet 5 that opens to the upstream side 26 of the element 3 is formed on the outer peripheral surface, and an downstream side 27 of the element 3 opens at the other end. An outlet 6 is formed. The inlet 5 side is connected to an air intake (not shown), and the outlet 6 side is connected to an intake part (not shown) of the engine.

A short pipe 8 having one end closed and the other end communicating with the outlet 6 is mounted in the main body 2. The short tube 8 is fixed to the main body 2 via a ring-shaped partition plate 9 fitted on the outside. A bolt body 10 is provided at one end of the short pipe 8, and a plurality of communication holes 11 for communicating the inside and the outside are formed on the outer peripheral surface.

The element 3 is formed in a cylindrical shape, a first end plate 13 having a through hole 12 that can be inserted into and removed from the bolt body 10 is provided at one end, and the short pipe 8 is provided at the other end. A second end plate 15 having a through hole 14 that can be freely inserted into and removed from is provided. A wing nut 16 for tightening and fixing the element 3 to the short pipe 8 is screwed onto the bolt body 10. A baffle scarf 17 that covers the wing nut 16 is detachably fitted to one end of the element 3.

The element replacement port 4 is provided with a lid 19 which can be opened and closed. The lid 19 is formed in a cylindrical shape with one end closed, and is clamped and detachably fixed to one end of the main body 2 by a clamp band 20.

As shown in FIG. 2, reference numeral 21 is a compressor of an air-hydraulic hybrid brake device equipped in an industrial vehicle. An air tank 22 is connected to the compressor 21, and a brake system is provided downstream of the air tank 22. 23 is connected. The air tank 22 and the downstream side 26 of the element 3 are connected by a pipe 24, and a cock 25 (an example of a switchgear) is provided in the pipe 24. That is, the front end of the pipe 24 penetrates the outlet 6 side of the main body 2 and the partition plate 9 and projects into the element 3.

The operation of the above configuration will be described below. The air compressed by the compressor 21 is stored in the air tank 22 and supplied to the brake system 23 as needed. Further, the air flowing into the body 2 from the inlet 5 of the body 2 is from the upstream side 26 of the element 3 (that is, the outer peripheral surface side of the element 3) to the downstream side 27 of the element 3 (that is, the inner peripheral surface side of the element 3) ), Dust and the like are removed at this time, then flow into the short pipe 8 from the communication hole 11, and are supplied to the intake portion of the engine through the outlet 6.

When cleaning the element 3, as shown in FIG. 2, the clamp band 20 is loosened, the lid 19 is removed, the element replacement port 4 is opened, and the cock 25 is opened. As a result, the compressed air in the air tank 22 flows back from the downstream side 27 of the element 3 to the upstream side 26 via the pipe 24, and at this time, the dust 28 attached to the element 3 is blown off to the upstream side 26 and blown away. The dust 28 is discharged to the outside through the element replacement port 4. After cleaning, the cock 25 is closed, the lid 19 is attached to close the element replacement port 4, and the clamp band 20 is tightened.

As described above, the cleaning of the element 3 can be performed while the element 3 is still mounted in the main body 2, and therefore it is very easy. Moreover, since the compressed air used for the vehicle's own pneumatic-hydraulic combined brake device is also used for cleaning, the element can be easily cleaned even in a place where there is no compressed air supply facility.

When replacing the element 3, the lid 19 may be opened, the baffle scarf 17 may be removed, and then the wing nut 16 may be removed to pull out the element 3 from the short pipe 8.

In the above embodiment, since the wing nut 16 is covered with the baffle scarf 17, it is possible to prevent the wing nut 16 from loosening due to the fluid pressure of air.

[0020]

[Effect of device]

 As described above, according to the present invention, when the element is cleaned, the lid is opened and the opening / closing device is opened, so that the compressed air in the air tank flows backward from the downstream side of the element to the upstream side through the pipe. At this time, dust adhering to the element is blown off to the upstream side and discharged to the outside through the element exchange port.

As described above, the cleaning of the element can be performed while the element is still mounted in the main body, which is very easy. Further, since the compressed air used for the air brake device of the vehicle itself is also used for cleaning, the element can be easily cleaned even in a place where there is no compressed air supply facility.
