Description

  The present invention relates to a dust absorber for dust generated at a construction site, a factory, or the like.

Conventionally, a vacuum generator that generates suction force is attached to the lower part of the vacuum cleaner body, and a suction port and a discharge port for discharging purified air are provided on the side of the vacuum cleaner body. Separately removes dust, water, and filth, and a filth collection tube with a filter is detachably installed inside the main body of the vacuum cleaner. The exhaust passage that discharges the purified air and the motor cooling passage that passes through the bypass motor that constitutes the vacuum generator are joined together and exhausted from the exhaust port to open and close the lightweight lid. There is a wet-dry vacuum cleaner that makes it easy. (For example, refer to Patent Document 1.)
Japanese Patent Application Laid-Open No. 2004-113760. (Fig. 5)

  The exhaust flow path of the bypass motor according to the present invention discharges clean air from the waste passage cylinder and the second flow path portion that flows through the inside of the lid, the second flow path portion, and the discharge port. Since the first flow path portion is provided and the bypass motor cooling path for cooling the bypass motor itself is provided, there is a problem that it is necessary to use a high-power bypass motor for exhaust.

  Therefore, the present invention is provided with an intake motor and a turbo blower, and induces a flow of clean main suction air in which dust is collected by a filter by the action of the turbo blower and a flow of motor cooling air by the action of the intake motor. The purpose is to join and discharge by the generation of air.

  The present invention provides a dust collector having a suction port on a side wall of a main body and a filter inside a dust collection tank, and a cylindrical fan case containing a turbo blower can be fitted into and removed from an upper opening of the dust collection tank. Cover the fan case's side wall with an exhaust port, cover the top opening of the fan case with a vent hole, place the intake motor, and place the motor cover on the intake motor with the vent hole A cover with a ventilation window is slidably fitted onto the fan case, and the outside air sucked from the ventilation window is released from the inside of the intake motor and the ventilation holes provided in the motor peripheral wall to The cooling air flow from the fan case exhaust port to the intake motor cooling air flow by the induced air flow generated in the air vent of the fan case top plate due to the action of the main suction air flow by the operation of the turbo blower. It is combined the 引空 airflow is to drain.

  Dust generated at construction sites, factories, etc. accumulates in a dust collection tank equipped with a filter cylinder by the action of main suction air from a suction port by a turbo blower.

  Fine dust in the air is collected by a filter, and clean air is discharged to the outside from the exhaust port of the fan case.

  The outside air sucked from the ventilation window passes through the inside of the intake motor and is discharged from a vent provided in the side wall of the motor to cool the intake motor.

  The air that has cooled the intake motor merges into the fan case from a vent hole provided in the top plate, and is discharged to the outside through the exhaust port of the fan case by the attraction action of the main suction air by the turbo blower.

Fig. 6 is a perspective view showing a state in which a cover is placed on the intake motor so that cooling air is not leaked from the lid body. Fig. 6 is a perspective view showing a state where the lid body is removed from the dust collector body, dust is sucked from the suction port, and coarse dust is collected. FIG. 7 is a perspective view showing a state in which fine dust is accumulated in a dust tank, fine dust is collected by a filter, and clean air is sent into the fan case by an attracting action of main suction air by a turbo blower. FIG. 7 is a bottom view showing the fan case. It is.

  A suction port 2 is provided on the side wall 1a of the dust suction machine main body 1 for sucking dust containing cut materials in a construction site or factory. The filter cylinder 3 in which the filter group 3 a is arranged is erected in the dust collection tank 4 while holding the side wall 1 a and the space, and the fan case 5 is detachably covered in the upper opening of the dust collection tank 4. Fix with the mounting bracket 6. The short cylindrical fan case 5 includes a bottom plate 7 provided with a screw hole 7a in the center, a donut-shaped top plate 8 provided with an opening 8a in the center, and a cover plate 9 covering the opening 8a. A central shaft 11 that supports the turbo blower 10 rotatably is installed over the center of the hole 7 a and the cover plate 9. The side wall of the fan case 5 is provided with an exhaust port 5a for discharging the main attraction air of the turbo blower 10, and a baffle plate 5b for blocking the exhaust from the exhaust port 5a and blowing it downward is provided. A plurality of vent holes 9 a are provided in the cover plate 9, and a frame 13 provided with radial protrusions is mounted on the cover plate 9 to mount the intake motor 12. A plurality of vent holes 12 a are mounted on the peripheral wall of the intake motor 12. The motor case 12b is covered with the air hole 9a of the cover plate 9 and the intake motor 12. A cover body 14 provided with a plurality of ventilation windows 14a is detachably covered with the fan case 5, and the outside air sucked from the ventilation windows 14a passes through the inside of the intake motor 12, and is further provided in the motor peripheral wall. The intake motor 12 is cooled by discharging the air from 12a. The air released to the outside of the machine is a main suction air flow from the suction port 2 by the turbo blower 10, and is induced from the exhaust port 5 a of the fan case 5 by the induced air flow generated in the vent hole 9 a provided in the cover plate 9. The cooling air flow and the main suction air flow are merged and discharged.

  In the figure, 15 is a fan case packing, and 16 is a ring for a fan case holder.

  Dust containing chips generated at construction sites, factories, etc. accumulates in the dust collection tank equipped with the filter cylinder by the action of the main suction air from the suction port by the turbo blower, and the fine dust in the suction air is filtered. The collected and harmless clean air is discharged to the outside from the exhaust port of the fan case, which is useful for environmental conservation at construction sites and factories.

Claims (1)

  In a dust collector equipped with a suction port on the side wall of the dust collection tank and a filter inside, a fan case with a built-in turbo blower is placed over the upper opening of the dust collection tank so that it can be freely inserted and removed and exhausted to the side wall of the fan case. An intake motor with a vent, a vent hole in the top plate that covers the top opening of the fan case, and a vent hole in the peripheral wall is placed on the top plate, and the motor cover is placed on the intake motor and ventilated. A lid provided with a window is slidably fitted onto the fan case, and outside air sucked from the ventilation window flows out from the inside of the intake motor and the ventilation holes to cool the intake motor, and is also mainly driven by the operation of the turbo blower. A feature of the suction air flow is that the cooling air flow of the intake motor and the clean main suction air flow are combined and discharged from the exhaust port of the fan case by the induced air flow generated in the ventilation holes of the top plate.
