Abstract

PURPOSE:To prevent a shock sound from occurrence and dust from clogging by providing a spiral blade inside a vertically long tubular dust chute provided with multiple dust insertion ports. CONSTITUTION:A dust chute 1 is formed with a straight tube extended vertically straightly, and dust insertion ports 2 are formed in positions corresponding to individual floors of a building respectively. A continued spiral blade 4 in the range from the upper end section to the lower end section of the chute l is provided inside the chute 1. The dust inserted through individual insertion ports 2 is slid down along the upper face of the spiral blade 4, no fall shock sound is generated, and dust clogging is prevented because there is no damper or bent section in the middle.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a dust chute.

[Prior Art] High-rise buildings and the like are usually equipped with dust chutes as equipment for collecting garbage from each floor to a collection site or the like. As the dust chute, Figure 4 (a) (b)
The one shown in (C) is conventionally known.

In FIG. 4(a), dampers 11 are provided at appropriate intervals in a straight tube-shaped shoe 10a;
) is one in which bent portions 12 are provided at appropriate intervals on the unit HOb. In addition, (C) is a plurality of single shoots 10c.
The chute units 10c are provided with their positions shifted in the left-right direction, and the individual chutes 10c are connected by screw connecting hairs 13 or the like.

[Problems to be Solved by the Invention] In each of the above-mentioned conventional dust chutes, the damper 11
The impact force when the garbage falls is absorbed at the bending part 12 and the connection position of the screw conveyor 13, but since each position receives the falling garbage, it is necessary to absorb the energy of the fall sufficiently. There is a problem in that a relatively large fall impact sound is generated because it cannot be absorbed.

In addition, at the connection positions of the damper 11 and the screw conveyor hair 13, the movement speed of the dust drops rapidly, so that the dust tends to accumulate, causing a problem that dust clogging is likely to occur.

Furthermore, in the dust chute shown in FIG. 4(b) (C1), since the shape of the chute expands in the horizontal direction, there is also the problem that a large space is required for installation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a dust chute that does not generate impact noise or clog the chute with dust, and does not require a large installation space.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a dust chute in which a vertically long tubular chute is provided with a plurality of garbage input ports at required intervals vertically. They adopted a structure in which spiral blades were installed inside the chute.

In addition, in the above configuration, in order to make the garbage fall smoothly, the spiral blade is continuous in the range from the upper end of the chute to the lower end, and in order to reduce manufacturing costs, The spiral blade may be composed of a single blade divided into a plurality of pieces, and the single blades may be provided at required intervals in the length direction of the chute.

[Effect]

With the above configuration, the garbage thrown in from the input port will be guided by the top surface of the spiral blade and will slide down.
There is no impact noise caused by the fall, and the product is transported downwards smoothly.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.

The chute 1 is formed of a linear tube extending straight in the vertical direction, and is provided in a range from the upper floor to the lower floor of the high-rise building B.

This chute 1 has a garbage inlet 2 formed at a position corresponding to each floor, and the inlet 2 has a door 3 that can be opened and closed.
is provided.

Also, inside chute 1! This is a continuous spiral blade 4 from the upper end of the chute 1 to the lower end ↓.
is provided.

This spiral blade 4 has no interfering object such as a mandrel in the center, and its outer peripheral edge is fixed to the inner wall of the chute 1.

Further, a rotary tram R for collecting garbage is connected to the lower end of the chute 1 via a hopper 5. This rotary drum R is provided with a spiral feeding blade 6 on its inner circumferential surface, and as it rotates, it stores the thrown-in garbage in a compressed state.

In the dust chute constructed as described above, when dust is thrown into each input port 2 of the chute 1, the dust slides down the upper surface of the spiral blade 4.

At this time, there is no impact noise because there is no falling garbage, and
Since the garbage slides down continuously, the garbage does not accumulate on the way and is smoothly conveyed downward.

In the embodiment, the spiral blade 4 is shown as being continuous from the upper end to the lower end of the chute 1, but the invention is not limited to this. They may be provided at required intervals in the length direction. At this time, they are placed at intervals where impact noise does not become a problem.

In addition, the mid-oblique angle of the spiral blade 4 is preferably set at a relatively large angle to ensure that even if the type of garbage changes, it can slide off, and an angle of 60° or more is usually appropriate. .

〔effect〕

As described above, in this invention, a spiral blade is provided inside the chute, and the debris is made to slide down along the surface of the spiral blade, so that there is no impact noise caused by falling, and Since it is allowed to fall continuously without providing dampers or bent parts, there is no need to worry about dirt clogging, and the installation space is small.
