It is arranged with a gap of 1: 1: 2 and shifted downward in the depth direction. Of the remaining two baffles 14 and 15, one baffle 14 is the inlet 1
The baffle plate 15 is arranged so as to project from the upper side of the inner surface of the side face portion 102 provided with 06 to the lower side of the baffle plate 11 in the horizontal direction (downward in the horizontal direction in the figure). It is arranged so as to project from the upper side of the inner surface of the side surface portion 103 facing the side surface portion 102 toward the horizontal direction side (horizontal direction in the drawing). However, in the dust collector in which the analysis result of FIG. 13 is obtained, the discharge port 107 is arranged on the opposite side of the introduction port, and the three baffle plates 11 to 13 are the introduction port 106.
In the depth direction, facing the side surface portion 102 provided with 1:
It is provided at an interval of 1: 1.

As can be seen from FIG. 13, by providing the baffles 11 to 14 as described above, it is possible to make the fluid 100 μm.
When dust with a particle diameter of about m is mixed, a part of the dust collides with the baffle plate 12, is shaken off, and is taken into the dust collecting chamber 1a.

When dust of about 50 μm to 100 μm is mixed in the fluid, all the dust directed to the discharge port 107 is discharged along the inner surface of the side surface portion 103 opposite to the side surface portion 102 provided with the introduction port 106. Head towards exit 107. Further, even when dust of about 10 μm is mixed, most of the dust that goes to the discharge port 107 goes to the discharge port 107 along the inner surface of the side surface portion 103. Therefore, as shown in FIG. 12, by further providing the baffle plate 15 on the flow path, dust with a particle diameter of about 10 μm to 100 μm can be preferably taken into the dust collecting chamber 1a.

As described above, according to this embodiment, the introduction port 106 is provided.

The cleaning frequency can be reduced.

Further, the plurality of baffle plates 11 to 15 are provided on both side surface portions 104 and 105 adjacent to the one side surface portion 102, and the closing plate 10 so as to face the both side surface portions 104 and 105.
Since the closing plate 108 is detachably attached to the other side surface portion 103 by being sandwiched by a pair of holding plates 109 standing upright from 8, the closing plate 108 can be removed from the housing 10. The baffles 12 to 15 sandwiched by a pair of sandwiching plates 109 standing upright from the housing 10 can also be removed from the housing 10. The baffles 12 to 1
It becomes easy to clean the dust adhering to 5.

Further, since the filter 16 is replaceably inserted into the housing 10 through the filter insertion port 105a, the filter 16 can be easily replaced. According to the arrangement structure of the dust collector 1 in the garbage processing machine 2 shown in FIG. 2 and the like, the filter cleaning door 29 is opened while the inlet doors above the processing tank 2a and the overflow tank 2b are closed. The filter 16 can be easily replaced at the insertion opening 105a. In this case, it is possible to prevent the odors in the processing tank 2a and the overflow tank 2b from leaking to the outside unnecessarily. Further, since the dust collecting device 1 comes outside the processing tank 2a and the overflow tank 2b, the filter 1
The user's hand is not exposed to the temperatures of the processing tank 2a and the overflow tank 2b when the 6 is replaced.

Further, the closing plate 108 and the pair of holding plates 109
And a plurality of baffles 12 to 1 held by these
5 is detachably attached to the side surface portion 103 in which the opening 108a is provided so as to close the opening 108a, the closing plate 108, the sandwiching plate 109, and the baffle plate 5 that are integrally formed. By removing 12 to 15 from the side surface portion 103, the dust accumulated in the dust collecting chamber 1a inside the housing 10 can be easily removed from the opening 108a of the side surface portion 103.

Further, the side surface portion 1 facing the side surface portion 102.
By arranging the baffle plate 15 so as to project from the upper side of the inner surface of 03 to the horizontal side, the dust toward the outlet 107 along the inner surface of the side surface portion 103 can be taken into the dust collection chamber 1a. More preferably, it is possible to prevent the filter 16 from becoming dirty with dust.

In the present embodiment, the discharge port 107 has a structure provided on the side surface portion 104, but the discharge port of the present invention is not limited to this, for example, the structure provided on the side surface portion 103, or The structure may be provided on the top surface portion 100. Even with such a structure, it is possible to obtain the same collection effect as that of the present embodiment.

Further, the side surface portion has a structure composed of four side surface portions, but the side surface portion of the present invention has, for example, a regular octagonal cross section if the arrangement structure of each portion is the same as that of this embodiment. The structure may be composed of eight side surface parts, or may be a structure composed of a cylindrical side surface part or the like. Even with such a structure, it is possible to obtain the same collection effect as that of the present embodiment.
