Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dust removal facility installed in a drainage channel or the like to remove dusts flowing in the drainage channel. More specifically, the present invention relates to a dust removal facility having an openable / closable screen for capturing and removing dusts flowing in a drainage channel.

[0002]

[Prior art]

 Conventionally, a dust remover has been generally disposed as a means for removing dusts flowing down a drainage channel or the like. The garbage to be removed by the dust remover is related to the contamination of rivers, etc., and is a wide variety of materials such as wood, paper, cloth, etc., vinyl, plastic, bottles, cans and other so-called garbage. The dust remover has a means for capturing dust and a means for scraping and collecting the captured dust, and various devices have been proposed in accordance with the combination. There is a screen as a means for capturing dust, and a rake device as a means for scraping and collecting the captured dust.

A screen using wires will be described. Conventionally, as shown in FIG. 7, a screen bearing 51 is provided on an upper portion of a screen 50 so as to normally open and close the screen, and an opening 52 for dust treatment is provided. A bearing 53 is also arranged on the concrete side of the floor surface, and a shaft 54 is interposed therebetween so that the screen 50 is swung about the bearing. Further, when opening and closing the screen 50, a wire rope 55 is connected to the tip or intermediate portion of the screen 50, and the wire rope 55 is wound up and closed by an opening / closing device 56 provided on the concrete floor above the waterway weir. .

When the water channel is deep, the screen 50 is slid and stacked in a two-stage manner as shown in the figure, and the screen 50 is lifted to the outside of the opening 52, that is, to the position shown by the two-dot chain line as shown in the figure. I have. However, in this structure, the distance from the screen bearing 51 of the opening 52 to the tip of the screen 50 is shorter than the retaining wall 57 of the water channel. In many cases, the retaining wall 57 could not be opened and closed.

[0005] In the dust removing device including the screen 50, the screen reinforcing material is generally made of a shaped steel or a steel plate. Further, the screen 50 itself is also made of a shaped steel, a steel plate, a steel pipe material or the like. The same applies to the bearings 51, 53 and the like. The opening / closing device 56 for the screen 50 is composed of an electric motor, a speed reduction means, a wire rope 55, a wire rope winding drum, and the like, and this configuration is known. A rake is used as a means of scraping garbage.

[0006] As described above, especially in a deep water channel or the like, a method is adopted in which the screen is made into a multi-stage structure of a sliding type, or a guide type is used to forcibly collect and collect dust. Many have complicated structures. For example, as disclosed in JP-A-5-331821, a rake is transferred from an undulating screen to a rake to collect dust above the waterway, or as described in JP-A-10-12441, dust is captured by the screen. It is also known that wire ropes are used to collect dust and dirt out of the water surface on waterways via rails.

[0007] On the other hand, the rake device is a device in which the captured dust is lifted up and down on a guide of the dust remover by a rake that moves up and down, and the dust is removed from the surface of the water while being transferred to the rake to remove dust. It is designed to be carried over the aircraft and collected. Also, dust on the screen that could not be removed by the rake was manually removed as appropriate. In particular, strings such as vinyl and cloth attached to the screen bar are removed directly with a rake or the like through human intervention.

[0008]

[Problems to be solved by the invention]

 However, for example, vinyl strings on the screen bar are difficult to remove easily and require some manual work. It was difficult to scrape and collect all the waste with a conventional rake. Regarding the configuration of the above-mentioned publication, in the former, a screen is planted at the bottom of a water channel so that it can be raised and lowered with a wire, and in this process, dust is transferred from the screen to a dust bin, and the dust bin is guided by a guide rail. The garbage is guided to the garbage and carried to the garbage receptacle on the upper surface of the channel weir to collect garbage.

[0009] The latter is configured such that after the garbage is captured, the vertically movable grid-like screen is raised via a guide rail, and the screen is carried on the ground surface of the upper wall of the waterway and turned upside down to collect garbage. Both are configured to collect garbage on the ground via guide rails. As described above, the device with the guide rail has a problem in that the configuration is inevitably complicated and the cost is high, and the frequency of occurrence of troubles in the guide portion is increased.

[0010] On the other hand, a system in which only the screen is swung to open and close has a simple structure, but requires an enlarged opening in a water channel, and is difficult to apply to a deep water channel. there were. Manually removing these debris directly from the screen was dangerous, and there were also safety issues. In addition, the screen itself is tilted, including the guide of the rake, and is completely lifted off the water surface to automatically remove dust.

However, since it is impossible to completely remove dust such as vinyls, it is absolutely necessary to remove the dust manually, and even if it is automatically processed, the dust removing effect corresponding to this is small and there is a problem economically. Was. In small-scale waterways with few opening and closing operations that are expected to reduce the amount of garbage, complicated devices are not necessarily required. Thus, there is a need for a simple and low-cost dust removal facility that is suitable for small-scale waterways and also for relatively deep waterways and that can easily remove dust.

The present invention achieves the following objects in order to solve these conventional problems. The purpose of the present invention is to make the screen simple, and to support the upper screen by projecting the end of the screen into the opening of the channel weir. It is an object of the present invention to provide an openable screen dust removing device that is disposed on a road so that a deep portion of refuse can be easily collected. Another object of the present invention is to provide an openable screen dust removing apparatus having a simple structure and a low cost structure.

[0013]

[Means for Solving the Problems]

 The openable screen dust removal equipment of the present invention is a dust removal equipment installed in a waterway, wherein a base that rotates in a vertical direction in the waterway through a fulcrum provided in the waterway, and is swingable on the base. And a screen that catches dust flowing down by blocking the water channel and opening and closing the screen by rotating the screen in the up and down direction. And an opening / closing device provided in the upper part of the channel to wind up the wire.

The base may be a reinforcing girder made of a steel material. Further, the screen may be divided into an upper screen and a lower screen, and the upper screen and the lower screen may be configured to be relatively rotatable via a support shaft provided on the base. . Further, the base may be a steel reinforcing girder configured to be bent.

[0015] Furthermore, the screen may have a structure in which an upper end portion of the screen is extended and supported by the opening, and is rotatable via a support shaft provided on the base. Further, the opening may be provided with a guide portion for a projecting guide operation of the screen. Further, the upper screen extended and supported by the opening may be swingable via a support shaft of the lower screen fixed to the base.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) Figs. 1 to 3 show the overall configuration of an openable screen dust removing apparatus to which the present invention is applied. Fig. 1 is an overall side view, Fig. 2 is an overall front view, and Fig. 3 is an overall plane. FIG. FIG. 4 is a partial detailed view of FIG. As shown in the figure, the openable screen dust removing apparatus 1 of the present invention is provided in a state of blocking a water channel. The openable screen dust removal equipment 1 mainly includes a reinforcing girder 6 for a screen and a supporting portion thereof, a screen 2 for capturing dust, a wire rope 13 for lifting the screen 2, and a switchgear for winding up the wire rope 13. 14 is a basic configuration.

The reinforcing girder 6 is made of a shape steel, a steel plate or the like, and is composed of a vertical reinforcing girder 6a and a horizontal reinforcing girder 6b straddling the vertical reinforcing girder 6a and reinforcing the vertical reinforcing girder 6a in the horizontal direction. ing. The lateral reinforcing girders 6b also bear the load applied to the screen 2. The vertical reinforcing girder 6a is provided on each side of the waterway. A reinforcing girder bearing 7 is provided on the upper end of the reinforcing girder 6. On the other hand, two concrete-side bearings 8 are provided on both sides of the concrete wall in the waterway by mounting bolts 8a on the waterway ceiling C which is the lower surface of the concrete wall covering the upper part in the waterway. . As shown in FIG. 1, the mounting position of the concrete-side bearing 8 is set such that when the retaining wall F is present in the water flow direction, the front end portion E of the screen 2 avoids interference with the retaining wall F. .

The reinforcing girder bearing 7 of the above-mentioned reinforcing girder 6 is rotatably connected to a concrete-side bearing 8 via a shaft 9. The shaft 9 is inserted across the two bearings 7 and 8, and is attached by a washer / pin 9a as shown in FIG. The screen 2 is mounted on the reinforcing girder 6, and the screen 2 is divided into a lower screen 3 and an upper screen 4. The lower screen 3 and the upper screen 4 are mutually rotatable via a support shaft 5. In the embodiment, the lower screen 3 is fixed to the reinforcing girder 6, and only the upper screen 4 rotates with respect to the lower screen 3.

The lower screen 3 is fixed on the reinforcing girder 6 at two locations, an upper end and a lower end, by mounting bolts 3g via fixing brackets 3f. The upper end 4f of the upper screen 4 protrudes from the trash disposal opening D on the waterway weir to the surface of the ground, and is supported while sliding over the upper screen guide 10 of the concrete upper wall of the waterway weir. ing. The upper screen guide 10 is an L-shaped steel plate and is embedded in a concrete wall. The upper screen guide 10 is of a sliding type according to the shape of the opening D for dust treatment, but may be of a roller guide type.

The upper screen 4 is supported by the upper screen guide 10 and can swing while sliding. The lower screen 3 is formed by arranging a plurality of long and thin screen bars 3a in parallel at predetermined intervals. A pipe-shaped spacer 3b is inserted between the screen bars 3a, the screen bar 3a is sandwiched by assembling bolts 3c, and fixed by nuts 3d via washers 3e. This attachment is provided at a plurality of locations according to the length of the screen bar 3a. The upper screen 4 is also structurally similar to the lower screen 3, and a plurality of screen bars 4a are sandwiched between spacers 4b and assembled via assembly bolts 4c, washers 4e, and nuts 4d.

The connecting portion between the upper portion B of the lower screen 3 and the lower portion A of the upper screen 3 is supported by a support shaft 5 so that the screen bars 3a and 4a overlap with each other and are relatively rotatable. As in the case of each of the upper screen 4 and the lower screen 3, a spacer 5a is inserted between the screen bars 3a, 4a, and is fixed by an assembly bolt 5b as a support shaft and a nut 5d via a washer 5e. are doing. On the other hand, at the intermediate position of the reinforcing girder 6, a screen 2 lifting metal fitting 12 is provided, and one end of a wire rope 13 is connected to the hanging metal 12. The other end of the wire rope 13 is wound around a wire drum 14a of an opening / closing device 14 installed on a concrete upper wall.

The two wire drums 14a are provided on both sides, and are rotationally driven by one motor 14b. The opening / closing device 14 is provided and fixed at the edge of the dust treatment opening D of the waterway weir. The wire rope 13 is suspended below the waterway through the dust treatment opening D, Suspends the reinforcing girder 6 to which the screen 2 is attached. Therefore, the opening / closing device 14 opens and closes by moving the screen 2 up and down through the wire rope 13. When raising the screen 2, the wire drum 14 a is reversed and the wire rope 13 is rewound, and the wire rope 13 is forcibly raised by the driving force of the opening / closing device 14, and when lowering the screen 2, the screen 2 is lowered by its own weight.

When the screen 2 is pulled down, the upper screen 4 does not come off from the upper screen guide 10 of the concrete upper wall. The reinforcing girder 6 is configured to be swingable about a shaft 9 and is installed so as to be inclined (approximately 60 degrees) toward the upstream in the water flow direction, and receives dusts flowing from the upstream. The garbage trapped on the screen 4 is lifted up by a rake and processed. Further, when a large amount of dust is retained, the reinforcing girder 6 swings on the water bottom and the water surface around the shaft 9 and when the dust is lifted above the water surface, the dust is collected by a rake (not shown). . When the reinforcing girder 6 is lifted, the garbage disposal opening D is covered with the screen 2, so that there is no danger of accidentally falling into the waterway during operation.

Further, the collected dust is scraped out of the upper screen 4 at a position away from the dust processing opening D, so that the safety of the work is ensured. If the reinforcing girder 6 is long, there is a possibility of buckling due to water pressure. Therefore, the reinforcing girder 6 is supported by the reinforcing girder receiving member 11 fixed to the channel wall with the anchor bolt 11a. When the reinforcing girder 6 is short, the reinforcing girder receiving member may not be provided.

The reinforcing girder receiving member 11 is made of a steel plate, a mold steel or the like. When the reinforcement girder 6 is pulled down to the bottom, the tip is in contact with the bottom and is received. When the scraping operation is not performed, the screen 2 is lowered and installed in the waterway. In this case, the waste disposal opening D is in an open state. This opening is dangerous, especially if this equipment is located near a residential area. After the work is completed, all the equipment exposed on the ground surface is covered with the cover 15 as shown in FIG.

Embodiment 2 Although Embodiment 2 is shown in FIG. 5, the reinforcing girder according to Embodiment 1 is attached in a bent shape. The reinforcing girder 20 has a bearing 21 portion attached to a concrete-side bearing 22 via a shaft as described above. The difference from the above is that the concrete-side bearing 22 is attached to the back of the waterway ceiling C, and the concrete-side bearing 22 is protruded long toward the waterway side. Regarding the screen 2, both the lower screen 3 and the upper screen 4 have the same configuration as described above.

The dust processing opening D has a size corresponding to the shape of the lower screen 3, and an opening / closing device 14 is installed at an edge of the dust processing opening D. The wire rope 13 is connected to the reinforcing girder 20 at the lower end of the lower screen 3. The wire rope 13 is wound up by the opening / closing device 14 in a nearly vertical state. When the reinforcing girder 20 is lifted up by winding the wire rope 13, the lower screen 3 is installed horizontally at the position of the garbage disposal opening D as shown in the figure. The upper screen 4 is guided by an upper screen guide 10 and is brought obliquely upward.

The configuration is the same as that described above, except for the related devices that change with the bending configuration of the reinforcing girder 20. The feature of this embodiment is that the lower screen 3 can be installed in the opening with the entire surface being in a state of being coincident with the opening of the garbage disposal opening D. Garbage tends to accumulate near the lower screen 3 due to its weight during the lifting process. In this configuration, since the lower screen 3 is exposed, it is easy to scrape out dust. When the lower screen 3 is further pulled up with respect to the configuration shown in the figure, the inclination of the upper screen 4 becomes gentle. It is sufficient to determine where the garbage accumulates and determine the lifting height according to the situation at the site.

Embodiment Mode 3 This embodiment mode is shown in FIG. 6, but has an integral structure without dividing the screen. A support shaft 31 for swinging the screen 30 is provided at the lower end of the reinforcing girder 6. When the reinforcing girder 6 is pulled up by the wire rope 13, the screen 30 integrated with the support shaft 31 is swung about the support girder 31. It is moved to the refuse disposal opening 32. The configuration in which the reinforcing girder 6 swings around the shaft 9 provided on the waterway ceiling C is the same as in the first embodiment. The upper end of the screen 30 is supported by the screen guide 10 on the concrete upper wall as described above. The refuse disposal opening 32 is wider than the above-described configuration in order to secure a space for trash removal.

If the size of the dust processing opening 32 is set so as to pass through the screen 30, the screen 30 can be brought to the upper surface of the dust processing opening 32. Since the opening 32 for refuse disposal is wide, the opening / closing device 14 is installed at a position shifted rearward, and the connecting position of the wire rope 13 to the reinforcing girder 6 is also shifted downward. When the screen 30 is raised, it has a gentle slope. The garbage is scraped off with a rake or the like as described above. The feature of this configuration is that the screen 30 is an integral and simple configuration. Although it is not suitable for deep waterways, it is relatively shallow and low cost is suitable for simple installation.

As described above, the embodiment of the present invention has been described with three examples, but it is needless to say that the present invention is not limited to this embodiment.

[0032]

[Effect of the invention]

 As described above, the openable screen dust removal equipment of the present invention has a structure in which the screen is divided into two parts, and the upper screen is projected and supported by the upper screen guide of the garbage disposal opening to swing. In addition, the structure of the dust removal equipment has been simplified, and trash in deep waterways can be easily and easily raised to the surface of the water, making collection easier. In addition, the trash can be collected and collected at a position distant from the opening, thus ensuring the safety of work. The simpler configuration results in low-cost equipment and great economic effects.
