Abstract

PROBLEM TO BE SOLVED: To detect leakage of dust collection from a filter by a simple method by providing a window part on the side of an intermediate room provided between a fan and the filter and providing a transparent cover made of a transparent substance on the window part. SOLUTION: An intermediate room 18 exists between a fan 3 and a filter 5 and a window part 19 is provided on the side face of the intermediate room 18 and a transparent cover is fixed on the window part 19 under a removable condition through a packing, a screw, etc. The transparent cover consists of a transparent substance, e.g. an acrylic sheet, a glass sheet, etc. Then, if dust leaks from the filter, it is contaminated by sticking of the dust and the transparency disappears and the inside of a machine body becomes invisible from the outside of the machine body. Therefore, it is possible to easily detect leakage of dust from the outside of the machine body caused by contamination of the transparent cover.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to means for detecting dust leakage from a filter section in a dust collector using a filter.

[0002]

2. Description of the Related Art In a dust collector that filters and collects with a filter, dust to be collected is blown out to the outside of the machine body when the filter is worn, damaged, or incompletely mounted.

Therefore, conventionally, it has been necessary to periodically perform disassembly and inspection to find the above-mentioned problem, and as another method, a dust concentration detecting device or the like is provided on the downstream side of the filter.

[0004]

The above-mentioned method of overhauling and checking has a problem that the fan and other electric parts are damaged due to delay in discovery. Further, the detection device described later has a problem that the structure is complicated and the cost is increased.

An object of the present invention is to solve the problems of the prior art and to provide a filter type dust collector which can detect dust collection leakage from the filter section by a simple method.

[0006]

The above object can be achieved by providing a transparent cover on the side surface of the intermediate chamber between the fan and the filter so that the inside of the aircraft can be seen from the outside of the aircraft.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the dust collector according to the present invention will be described below with reference to the drawings. Dust 11 from fan 3
The air sucked together is discharged from the suction port 10 through the filter 5, the fan 3, and the discharge port 9 to the outside. On the other hand, the dust 11 is filtered and collected by the filter 5.
An intermediate chamber 18 is provided between the fan 3 and the filter 5, and a window portion 19 is provided on a side surface of the intermediate chamber 18, and the window portion 19 is provided.
A transparent cover 17 is detachably fixed to the cover via a packing 15, a screw 16 or the like. Transparent cover 17
Is made of a transparent material such as an acrylic plate or glass, and when dust is leaked from the filter, the dust adheres to the filter to make it dirty and the transparency disappears so that the inside of the body cannot be seen from the outside of the body.

Therefore, it is possible to easily detect the dust leakage from the outside of the machine due to the contamination of the transparent cover 17, and accordingly, the dust blowout and the dust emission from the discharge port, which has been a problem so far, are generated. It is possible to prevent damage to the motor, fan, and other devices caused by the buildup and blow-by.

[0009]

According to the present invention, since the transparent cover which allows the inside of the machine body to be seen from the outside of the machine body is attached to the side surface of the intermediate chamber between the fan and the filter, dust can be collected from the filter by a simple method. Can be detected.
