Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dust collector, and more particularly, it is suitable for use when the suction port of the dust collector cannot be provided close to the dust source.

[0002]

[Prior art]

 As is well known, a dust collector is used as a device for removing dust such as thread waste, fibers and paper accumulated on the cleaning surface. When using the above dust collector, the suction port of the dust collector is brought close to the dust on the cleaning surface so that it is sucked together with air.

When cleaning dust such as thread waste, fibers and paper accumulated on the cleaning surface as described above, in order to perform efficient cleaning, the suction port of the dust collecting device should be as close as possible to the dust. Need to kick. This is because the suction force drops sharply in proportion to the distance from the suction port. For this reason, it is desirable to bring the suction port closer to the distance within the diameter dimension D of the suction port of the dust collector, as shown in FIG.

However, there are cases where the suction port of the dust collecting device cannot be brought close to the dust depending on the condition of the cleaning surface. In such a case, the amount of dust collected is small relative to the amount of air sucked in from the suction port of the dust collector, and the suction efficiency is reduced.

Therefore, when the suction port of the dust collecting device cannot be brought close to the dust on the cleaning surface, an air cover is provided between the dust collecting device and the peripheral surface of the dust collecting port. Tens may be provided.

FIG. 11 shows an example in which an air-caten is provided between the hood and the dust generating source to improve the dust collecting efficiency. In FIG. 11, 100 is a suction port of the dust collector, 101 is a hood attached to the suction port of the dust collector, and 102 is an air blow of compressed air located on the peripheral surface of the hood 101. It is an outlet and is provided to form an air-curtain. Further, 103 is a dust to be collected.

[0007]

[Problems to be solved by the device]

 In the dust collector thus constructed, the blocking effect by the air-curtain is determined by the dynamic pressure and the thickness of the air-curtain. However, since the dynamic pressure and the thickness are limited due to economical efficiency, the effect of blocking cross winds is limited to about 5 to 6 m / s, and its utility value is low.

Further, in this air-curtain, since the air for the air-curtain (or special gas) is directly added to the processing air volume of the dust collector, a large amount of energy is required as a result. . For this reason, there is a problem that the advantages of the air-curtain cannot be utilized unless the economical efficiency is compared with the case where the suction amount is increased by a general dust suction hood.

In view of the above problems, an object of the present invention is to provide a technique capable of collecting dust on a cleaning surface with a small amount of energy.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has the following technical means. That is, this will be described with reference to the reference numerals in the accompanying drawings corresponding to the embodiments. In the present invention, the suction port 3 opened to the cleaning surface 4 having the dust 5 to be collected and the suction port 3 are sandwiched. And a pair of air outlets 2A for injecting compressed air 6 toward the cleaning surface 4, and the compressed air injected toward the cleaning surface 4 from each of the pair of air outlets 2A. The dust 5 is raised from the cleaning surface 4 by 6 and the compressed air 6 of two flows jetted from each of the pair of air-air outlets 2A collides with each other to direct the dust 5 raised to the suction port 3 In addition, the dust collecting apparatus is characterized in that the dust 5 is sucked through the suction port 3.

[0011]

[Embodiment of the invention]

 Next, embodiments of the invention will be described based on examples with reference to the drawings. FIG. 1 is a diagram showing a basic configuration of a first embodiment of the dust collector 1. 2 is a compressed air outlet nozzle and 3 is a suction port. The compressed air outlet nozzles 2 are for injecting compressed air 6 sent from a high-pressure blower or a compressor, and there are two compressed air outlet nozzles 2 facing each other across the suction port 3. The air outlets 2A of the respective compressed air outlet nozzles 2 are provided obliquely downward so as to incline toward each other in order to blow the compressed air 6 toward the cleaning surface 4 obliquely upward. Has been.

The suction port 3 sucks in the compressed air 6 injected from the pair of opposed air outlets 2 A toward the cleaning surface 4 when the compressed air 6 hits the cleaning surface 4 and rises. The cleaning surface 4 is cleaned by sucking in the dust 5 flying with the compressed air 6 as well.

There are various types of dust 5 described above. For example, lint, fibers, paper, cloth. These dust particles 5 are often relatively light in themselves, but may be very heavy when they are wet or contain oil. For this reason, even if an attempt is made to suck in with a considerably large force, it may not be possible to easily suck in if the distance between the suction port 3 and the dust 5 is large.

However, since the dust collector 1 of the present embodiment is configured as described above, the dust 5 on the cleaning surface 4 can be satisfactorily cleaned. That is, as described above, the dust collector 1 does not simply suck in the dust 5 but injects the compressed air 6 to fly the dust 5 into the air.

More specifically, when the compressed air 6 is jetted toward the cleaning surface 4 from the pair of air outlets 2 A facing each other with the suction port 3 in between, the jetted compressed air 6 hits the cleaning surface 4. To rise. Moreover, at this time, since the compressed air 4 is jetted from each of the two air outlets 2A facing each other, the two flows collide with each other, and the two flows can be raised toward the suction port 3. it can.

Then, the dust 5 is soared up toward the suction port 3 by the compressed air 6, and the dust 5 is carried to the vicinity of the suction port 3. As a result, even though the suction port 3 is installed at a position away from the cleaning surface 4, the dust 5 to be cleaned is carried to the vicinity thereof, so that the dust 5 can be satisfactorily cleaned with a small suction force. Can be sucked into.

Since the dust collecting apparatus 1 collects dust as described above, the energy required for sucking the dust 5 can be greatly reduced. By the way, in the dust collector 1, the energy for generating the compressed air 6 to be injected toward the dust 5 is required. However, the energy required to obtain the same wind speed is quite different on the blow side and the suction side. FIG. 9 is a diagram for explaining that the velocity of the fluid is different between the blowing side and the suction side.

In FIG. 9, when the wind velocity in the pipe of the blower 40 is, for example, 10 m / s, the positions of the wind velocity of 10 m / s on the blowing side and the suction side are as shown in (A) and (B). In this case, the distance (a) from the outlet side to the position (A) = 3000 mm, and the distance (b) from the suction side to the position (B) = 100 mm. Therefore, even if the wind speed is the same, the range of influence will be significantly different when blowing out and when inhaling.

Therefore, by injecting the compressed air 6 into the dust 5 as in the dust collector 1, the energy required to suck the dust 5 can be reduced. In other words, according to the dust collector 1, when the same energy is consumed, the efficiency of sucking the dust 5 can be significantly improved.

Next, a specific example of the dust collector 1 will be described with reference to FIG. 4, 7 is a subway work vehicle, 8 is a dust collector, 9 is a dust collection duct, 16 is a dust collection blower, 15 is a high-pressure blower or compressor, 10 is a rail, and 11 is a sleeper.

The subway work vehicle 7 is, for example, a vehicle used for cleaning dust 5 accumulated in a subway track. The dust collector 8 has a filter inside and collects only the dust 5 from the air containing the dust 5 sucked from the suction port 3. The dust collecting duct 9 has the suction port 3 opened downward. The dust collection blower 16 causes the suction port 3 to generate a suction force. The high-pressure blower 15 supplies compressed air 6 to each of the pair of compressed air outlet nozzles 2.

The subway work vehicle 7 configured as described above can clean the dust 5 accumulated between the rail 10 and the sleeper 11 well. That is, when cleaning the dust 5 accumulated between the rail 10 and the sleeper 11 by the subway work vehicle 7, first, the diagonally downward from each of the pair of air outlets 2A facing each other. And injects compressed air 6.

Since each of the air outlets 2A injects the compressed air 6 in a relatively wide range, the air outlets 2A are formed flat. A plurality of air outlets 2A may be provided in order to inject the compressed air 6 in a relatively wide range.

The compressed air 6 injected from each of the air outlets 2A hits the cleaning surface 4 and rises, as indicated by the arrow in FIG. At this time, the compressed air 6 injected from each of the air outlets 2A hits and is rectified, and rises toward the suction port 3. Then, the dust 5 between the rail 10 and the sleeper 11 is lifted up in the air by the compressed air 6.

The dust 5 floated up in the air is sucked through the suction port 3. The dust 5 sucked through the suction port 3 is carried into the dust collector 8 through the inside of the dust collecting duct 9. Then, air and dust 5 are separated in the dust collector 8 and the dust 5 is collected in the dust collector 8.

The subway work vehicle 7 collects the dust 5 as described above, so that the dust 5 accumulated between the rail 10 and the sleeper 11 can be cleaned well. The above-mentioned dust 5 is lint, fibers, paper, etc., and may be ignited by various causes if left unattended.

However, according to the dust collector 1, the compressed air 6 is jetted to the dust 5 from two directions, and the dust 5 is blown up into the air toward the vicinity of the suction port 3 and the suction is performed. Since the dust 5 that has risen near the mouth 3 is sucked from the suction port 3, the dust 5 located at a position apart from the suction port 3 is sucked in without increasing the suction force from the suction port 3 so much. Therefore, the dust 5 can be efficiently collected with a small amount of energy.

Therefore, according to the dust collector 1, it is possible to prevent the inconvenience that dust 5 such as yarn waste, fibers and paper which cannot be completely removed is accumulated and accumulated between the rail 10 and the sleeper 11. can do. For this reason, it is possible to reduce the number of causes of a fire in a subway yard that is difficult to find and extinguish.

The use of the dust collecting apparatus 1 is not limited to the subway work vehicle 7, and can be favorably applied to various work vehicles and other places.

Next, a second embodiment of the dust collector 1 will be described. Explaining the basic configuration of this example, two suction ports 3 are provided between a pair of air outlets 2A, and a pair of air outlets 2A other than the pair of air outlets 2A are provided between the two suction ports 3. There is another central air outlet 2B.

FIG. 7 is a specific diagram in which the dust collector 1 having the above-described basic configuration is applied to the subway work vehicle 7, and the two suction ports 3 and the central air-air outlet port 2B are the rails 1. It is provided so as to be located between 0 and the pair of air outlets 2A is provided outside the rail 10.

The compressed air 6 ejected from the pair of air outlets 2A collides with the compressed air 6 ejected from the central air outlet 2B to rise, and together with the dust 5, the two It is sucked from the suction port 3.

Next, a third embodiment of the dust collector 1 will be described. FIG. 8 is a diagram showing the basic configuration of this example, and in this example, two pairs of the pair of air-air outlets 2A are provided. The two pairs of air outlets 2A are located at right angles to each other.

[Effect of the invention]

 As described in detail above, the present invention injects compressed air from each pair of air outlets facing each other to cause dust to fly up into the air together with the air, and from each of the above air outlets. When the jetted compressed air hits, the direction in which the air containing dust rises is determined, and the dust flying in the air is guided to the suction port located between the pair of suction ports. Despite the fact that the suction port is installed at a position away from the suction port, it is possible to satisfactorily suck dust that is located away from the suction port with a small suction force, and the energy required to collect dust is required. − Can be significantly reduced.
