Description

[Detailed description of the invention] The present invention is a gas purification device typified by air purifiers, oil mist filters, dust collectors, air conditioning equipment, etc. The annular filter is removably directly connected to the output shaft of the motor at its axial center, and as the annular filter is driven and rotated, the gas to be filtered is forced to pass through the filter surface in an inward and outward direction. The present invention relates to a gas purification device equipped with a wind blowing blade.

Conventionally, as the above-mentioned gas purification device, for example, as described in Japanese Utility Model Publication No. 41-21271,
The air blowing blades are arranged concentrically inside the annular filter, and the annular filter and the air blowing blades are each driven by separate motors, so that the gas to be filtered is forcibly passed through the annular filter in the inner and outer directions. However, such a gas purifying device has the disadvantage that the entire device becomes large because each device is driven by a separate motor.

Therefore, as shown in FIG. 3, an annular filter 4' and a fan F which is adjusted at the axial center of the annular filter 4' so as to force the gas to be filtered to pass through the annular filter 4' in the inner and outer directions are installed. It is conceivable that the annular filter and the fan may be directly connected to the output shaft 8a of the motor 8, but in this case, the annular filter and the fan are basically separate structures, and during maintenance, they can be connected to the motor output shaft. Not only does it have to be attached and detached individually, which is cumbersome to handle, but the fan diameter is small compared to the diameter of the annular filter, and the force generated by the fan is small. However, since the system uses 100 MHz, the disadvantage is that the processing capacity is small compared to the overall size of the device.

On the other hand, as described in, for example, Japanese Utility Model Application Publication No. 53-132078, a gas purifying device of a type in which blowing blades are successively arranged along the circumferential surface of an annular filter, that is, as shown in FIG. 4 or As shown in FIG. 5, the wind fan blades 9 are fixed closely along the inner peripheral surface of the annular filter 4, and the annular filter 4 and the wind fan blades 9 are configured to rotate together. In this case, not only can the annular filter and fan be treated as one unit, that is, an annular filter with a fan, but also the fan diameter can be secured to be comparable to the diameter of the annular filter, and the motive force can be increased. , processing capacity can be increased relative to the overall size of the device.

The present invention relates to an improvement of a gas purifying device in which blowing blades are connected to the circumferential surface of an annular filter, which has the above-mentioned advantages, and makes it possible to manufacture the entire device at low cost by simplifying the structure. The purpose is to

The characteristic structure of this invention to achieve the above purpose is as follows:
In the gas purification device mentioned above, the filter surface of the annular filter is locally protruded toward the inside or outside of the annular filter to form the air blowing blade, and the following effects can be obtained from the configuration. play.

In other words, there is no need to separately manufacture the wind fan blades, and there is no need for a structure for connecting the wind fan blades and the annular filter, so the entire device can be manufactured at low cost while being easy to assemble and disassemble. can.

Furthermore, by partially protruding the filter surface to form the air blowing blades, the filtration area becomes wider than before, and the ventilation resistance of the filter can be further reduced.

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

A structure in which a filter paper 1 forming a zigzag filter surface a along the circumferential direction is interposed between annular plates 2, 2 facing each other in the axial direction, and a cylindrical punching metal 3 is provided on the inner peripheral surface. annular filter 4
is installed in a casing 7 having an intake port 5 from the shaft core and an exhaust port 6 in the tangential direction so as to be rotatable around the shaft core, and a disk-shaped side on the side where the intake port 5 is not formed. An electric motor 8 is attached to the outer surface of the casing portion 7A in such a manner that its output shaft 8a passes through the disc-shaped casing portion 7A at the shaft core,
The output shaft 8a of this motor 8, more specifically, the output shaft 8
The annular filter 4 is attached to the disk 8b attached to the
is installed.

Then, the filter paper 1 is locally protruded toward the inside or outside (the figure shows the inside) of the annular filter 4, and this protruding portion, specifically, the inside folded portion of the filter paper 1, Buffing blades 9 are formed from folded portions located at appropriate numbers in the circumferential direction,
A gas purification device is constructed that generates air so that the gas to be filtered is forcibly passed through the filter surface a from the inside to the outside as the filter 4 is driven and rotated.

Disc-shaped casing portion 7A of the casing 7
and the annular casing portion 7B are configured to be separable.

According to the configuration of the above embodiment, as the annular filter 4 with blades 9 is driven and rotated, the gas to be filtered is sucked in from the intake port 5, is filtered when passing through the annular filter 4, and is discharged from the exhaust port 6. The gas purification device configured as described above is used for purifying the air inside a room or a car.

Further, similar to the conventional example shown in FIG. 4, it may be configured to exhaust air in the axial direction on the opposite side from the intake port 5, and a device configured in this way can remove grease and odors. Therefore, it is very useful as a ventilation fan.

In addition, in the embodiment, the air blowing blades 9 are provided on the inside, but the air blowing blades 9 may be provided on the outside. Needless to say, it is also possible to configure and implement the system so that it passes through step 4.
