Description

[Detailed explanation of the invention] In recent years, with the large-scale development of chemical plants in particular, chimneys that also serve as pollution prevention have tended to become taller and larger in diameter.
Cleaning inside these chimneys has become a problem.

Various devices have been considered for this purpose, but they have some inconveniences, such as dangerous work, difficulty when inserting the device into the chimney, and problems with inspection after cleaning. are doing.

That is, for example, a guide arm equipped with a guide ring at its tip that is adapted to roll along the inner circumferential surface of the chimney is provided so as to overhang the outer periphery of the main body, which is intended to be suspended up and down, so that it can freely slide up and down using a spring mechanism. Furthermore, there is a structure in which a cleaning arm equipped with a brush at the tip extends from the main body so as to be able to swing up and down by a spring mechanism, and is rotated by a motor provided in the main body. In this method, when inserting the device from the narrow top end of the chimney, it is difficult to insert the device by bending the guide arm and cleaning arm, and the work is at a high place, which is dangerous. In addition, when performing inspections after cleaning, it is necessary to suspend another inspection gondola, etc., which makes the equipment expensive, increases work loss time, and extends the construction period. Since the brush is supported by a spring mechanism, the pressing force of the brush increases when the diameter of the chimney is small.In other words, the force to remove soot adhering to the inner wall of the chimney changes depending on the diameter of the chimney. However, it has the disadvantage that chimneys of various diameters cannot be cleaned uniformly.

The present invention can solve the drawbacks of the conventional method described above, and is capable of extending and contracting outwardly at at least three equally spaced positions on the outer periphery of the vacuum cleaner body, which is provided so as to be able to be lifted and lowered. A guide arm equipped with a guide roller is provided at the bottom of the vacuum cleaner body, and a rotating body having an outer diameter suitably smaller than the inside diameter of the chimney is provided at the lower part of the vacuum cleaner body, and flexibility is provided at a plurality of equally spaced positions on the rotating body. A brush having raised bristles around the center rod and having a larger weight than the hanging material is suspended and equipped via a hanging material having A chimney sweeper characterized by having an inspection deck with the same outside diameter as the rotating body, an inspection light at the top, and a ventilation fan that creates a downward flow of air. It is.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an example of the present invention, in which a vacuum cleaner main body 1 is suspended by a hanging hook 2, etc., and a guide roller 3 is provided on the outer periphery of the main body 1 at the tip. At least three telescopic guide arms 4 (four in this embodiment) are provided at equal intervals to restrict the lateral movement of the main body 1, and the length in the outward direction can be arbitrarily adjusted. There is.

An annular rotating body 7 is provided at the bottom of the vacuum cleaner body 1 and is rotated via a gear 6 by the drive of a motor 5 provided in the main body 1. A brush 8 is suspended at the position via a flexible hanging member 9 such as a chain.

The length of the hanging member 9 is selected depending on the relationship between the diameter of the rotating body 7 and the inner diameter of the chimney 15, the rotational speed of the rotating body 7, etc., and the brush 8 is attached to the center rod as shown in FIG. It has a shape with raised hairs around it, and has flexibility as a whole.
Moreover, it has such a length that its weight is greater than that of the hanging member 9.

Further, an inspection post 10 is attached to the upper part of the cleaner body 1.

In the figure, 11 is a light attached to the vacuum cleaner body 1, and 12 is a ventilation fan that creates a downward flow of air.

FIG. 3 is a detailed view showing an example of the configuration of the telescopic guide arm 4, in which the guide roller 3 is adjusted to have a large movement in the outer circumferential direction by a power cylinder 13, and a spring 14.
The slight movement is automatically adjusted.

In the above configuration, the rotating body 7 and the inspection pin 10 are configured to have dimensions considerably smaller than the inner diameter of the chimney 15.

When cleaning with the above-mentioned chimney cleaner of the present invention,
When inserting the vacuum cleaner of the present invention from the top of the chimney 15, the outer diameter of the entire vacuum cleaner can be made considerably smaller than the inner diameter of the chimney 15 by simply contracting the telescopic guide arm 4 and retracting the guide roller 3. (Rotating body 7 and inspection deck 10
(equivalent to the size of), so it can be inserted without any hindrance.

When cleaning, after extending the telescopic guide arm 4 and holding the cleaner body 1 at the center of the chimney 15 by the guide roller 3, the motor 5 is driven to rotate the rotating body 7 and the brush 8 is rotated. This is done by lifting and lowering the cleaner body 1 via the hanging hook 2 while bringing it into contact with the inner surface of the chimney 15 due to the centrifugal force.

At this time, the hanging material 9 only needs to have enough strength to support the brush 8 (it only needs to be small in weight), so if the length of the brush 8, which is relatively heavy, is set to a certain length, it will be effective. Since the weight of the bracket 8 is considerably larger than that of the hanging material 9, only the brush 8 can be moved inside the chimney 15 without the hanging material 9 coming into contact with the wall inside the chimney 15 when centrifugal force due to rotation is applied. It can be brought into contact with the inner wall to perform cleaning,
Moreover, since the brush 8 is suspended by a flexible hanging member 9, the brush 8 can be brought into contact with the inner wall of the chimney 15 with almost the same amount of force even if the diameter of the chimney 15 changes slightly. It becomes possible to perform uniform cleaning.

Furthermore, when performing the above-mentioned cleaning, the ventilation fan 12 blows air downward, thereby suppressing soot from rising during cleaning and preventing pollution to the outside. Since the brush 8 is suspended from the lower part of the main body 1 via the rotating body 7, the soot and deposits removed by the brush 8 will adhere to the upper part of the vacuum cleaner main body 1 and cause damage to the operating parts and other parts. There will be no inconveniences such as interference with the function of electrical equipment, causing breakdowns, or difficulty in maintenance.

Furthermore, even if there is a protrusion on the inner surface of the chimney 15, since the brush 8 is suspended by the flexible hanging material 9, the brush 8, the hanging material There is no impact or unreasonable force acting on the rotating body 9, the rotating body 7, etc.

When the cleaning is completed, an operator stands on the inspection pole 10 and suspends and lowers the cleaner body 1 while illuminating the inner surface of the chimney 15 with a light 11 for inspection.

At this time, since the brush 8 is hanging down, the chimney 15
There is no contact with the inner surface, so no soot scattering occurs during inspection.

Further, when the vacuum cleaner is taken out of the chimney 15, it can be easily carried out by the same operation as when inserting the vacuum cleaner.

It should be noted that the present invention is not limited to the above embodiments,
The rotating body can be rod-shaped instead of annular, the inspection pin can be of various shapes, and the telescopic guide arm and rotating body can be disassembled from the main body so that they can be assembled and disassembled in the chimney. Things you may choose to do;
Of course, various other changes may be made without departing from the gist of the present invention.

According to the above-mentioned chimney vacuum cleaner of the present invention, (i) By equipping the vacuum cleaner with an inspection stick and an inspection light, it is possible to perform both cleaning and inspection with one vacuum cleaner, and the equipment In addition to simplifying the process, efficient work is also possible by eliminating the trouble and time required to insert other devices for inspection.

(ii) By reducing the telescopic guide arm, the outer diameter of the vacuum cleaner can be reduced, so that it can be easily inserted from the top end of the chimney, where the diameter is small.

(iii) Since the brush is suspended via a flexible hanging material, even if the diameter of the chimney changes to some extent, the
The inner surface of the chimney can be cleaned in a stable condition, and even when there are protrusions on the inner surface of the chimney, no impact load is applied.

(iv) Since the length of the brush is determined so that the weight of the brush is greater than the weight of the hanging material, only the brush is brought into contact with the inner surface of the chimney due to centrifugal force, and the hanging material is in contact with the inner surface of the chimney. can be prevented.

(V) During inspection, the brush hangs down and does not come into contact with the inner surface of the chimney, so inspection can be carried out easily without scattering soot.

(Vl) Since a ventilation fan is provided to create a downward air flow to suppress the rise of soot during cleaning, it is possible to prevent pollution to the outside.

(■) Since the brush is suspended from the lower part of the vacuum cleaner body via a rotating body, soot and deposits that have been removed by the brush will not fall on the operating parts of the upper vacuum cleaner body. There is no possibility of failure due to malfunctioning of functions, and maintenance is also facilitated.

(■) By providing an inspection station, it can be used for repairs as well as inspections.

etc., exhibits various excellent effects.
