BACKGROUND OF THE INVENTION
The present invention relates to a wet dust collector, and more particularly to a wet dust collector that collects dust using water.
[0002]
[Prior art]
Conventionally, a wet dust collector that collects dust using water is known. This type of wet dust collector, for example, collects dust by spraying water or colliding water droplets with dust, and collects a large amount of flammable dust or bulky dust. Widely used for that.
[0003]
[Problems to be solved by the invention]
However, the wet-type dust collectors known so far need to be equipped with a sprayer for spraying water or a stirring blade (water wheel) for colliding water droplets, so the device configuration is complicated. In addition, it is inevitable to increase the size of the apparatus.
[0004]
This invention is made | formed in view of such a situation, The place made into the objective is to provide the wet dust collector which is excellent in portability with a simple and compact structure.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that an outflow part for allowing water to flow out is formed on the inner side, and a cylindrical inner cylinder in which an outflow port is opened at an upper end part ; An annular dust receiving portion that receives dust is formed between the inner tube and the outer tube, and a cylindrical outer tube that is open at the lower end is spaced from the inner tube. A cylindrical casing that is disposed separately and in which an annular water storage portion for storing water is formed between the outer cylinder , an upper lid that covers the outer cylinder and the upper end of the casing, and an upper lid Provided, disposed opposite to the water storage unit, connected to a suction means , provided to the suction unit for sucking the dust receiving unit, and provided on the upper lid, disposed opposite to the outlet, Suction means sucks from the suction part to create negative pressure In serial dust receiving portion, and a dust supply port for supplying the dust together with the air, the downstream side of the feeding means for feeding the water, is connected to the lower end of the outlet portion, of the liquid feeding means An upstream side is connected to the water storage unit, and the dust supply port and the outlet port can press the water supplied from the dust outlet port in the vertical direction against the water flowing out of the outlet port. And the outlet is configured to cause water to flow out toward the dust and air supplied from the dust supply port .
[0006]
According to such a configuration, when dust is supplied together with air from the dust supply port into the dust receiving portion which is sucked from the suction portion by the suction means and has a negative pressure, the dust is supplied by the supply pressure at which the dust is supplied. water flowing out is pressed from the supply port and the face shape provided we are in and outlet, it is ejected from the outlet like a fountain. For this reason, the dust received in the dust receiving portion is absorbed in contact with the water droplets that have become fine due to the jetting, so that efficient dust collection is achieved. Moreover, since it is a simple configuration in which the water flowing out from the outlet is ejected in a fountain state by the supply pressure of the dust in a state where the inside of the dust receiving portion is set to a negative pressure, a sprayer for spraying water, Or, it is not necessary to equip with a stirring blade (water wheel) to collide with water droplets, and it can be downsized with a compact structure, lighter and more portable, and easily carried to the site where dust collection is desired. Can do.
[0008]
In addition, while the dust is supplied downward from the dust supply port, the water flowing out from the outlet is spouted and spreads upward in the form of a fountain, so the dust received in the dust receiving part and the water spouted up Can be efficiently contacted with each other, and efficient dust collection can be achieved.
[0010]
In addition , after the dust received in the dust receiving portion comes into contact with the fine water droplets, the space between the peripheral side wall (outer cylinder) of the dust receiving portion and the peripheral side wall (inner cylinder) of the outflow portion is Good dust collection while falling with water. Therefore, more efficient dust collection can be achieved.
[0012]
Further , the dust receiving part is sucked by the suction means from the suction part through the water storage part from the lower end part. Therefore, in the dust receiving part, an airflow is generated from the upper end to the lower end around the peripheral side wall (outer cylinder) of the dust receiving part and the peripheral side wall (inner cylinder) of the outflow part. Then, after coming into contact with the finely formed water droplets, the particles are collected better while falling with the water along the air flow. Therefore, more efficient dust collection can be achieved. And the dust which fell to the lower end part of the dust receiving part moves to the water storage part from the lower end part, and is stored favorably in the water storage part.
[0014]
Moreover , since water is sent from the lower end part of a flowing water part toward the outflow port of an upper end part by the drive of a liquid feeding means, water can be jetted favorably in the outflow port. Moreover, the water droplet which fell to the lower end part of the dust receiving part after ejection moves to the water storage part from the lower end part, and is again sent to the lower end part of a flowing water part by the drive of a liquid feeding means from a water storage part. . For this reason, it is possible to efficiently circulate the water in the water reservoir and achieve efficient dust collection.

[0022]
The inner cylinder 4 has a cylindrical shape whose upper end is opened, and is arranged along the vertical direction with a distance from the outer cylinder 3 at the center in the casing 2, and the upper end thereof serves as an outlet 19. An opening is formed and the dust supply port 13 and the air supplied from the dust supply port 13 in the vertical direction are arranged to face each other with an interval that presses the water flowing out from the outflow port 19. It is connected to the. Further, a downstream side circulation pipe 20 projects from the lower part of the inner cylinder 4 outward in the radial direction. One end of the downstream circulation pipe 20 communicates with the inner cylinder 4, and the other end penetrates the casing 2 and extends to the outside of the casing 2, and is connected to the downstream side of the liquid feed pump 24 described later. It is provided to be.
[0023]
The upstream circulation pipe 10 and the downstream circulation pipe 20 are connected via a liquid feed pump 24 as a liquid feed means for sending water.
[0024]
And in this wet dust collector 1, the outer cylinder 3 is arrange | positioned inside the casing 2, and it forms as the triple cylinder structure by which the inner cylinder 4 is arrange | positioned inside the outer cylinder 3, The defined inner space serves as an outflow chamber 21 as a cylindrical outflow portion for allowing water to flow out, and includes an upper lid 5 (a disc portion surrounded by the outer cylinder 3) including a dust supply port 13; The inner space defined by the outer cylinder 3 is a cylindrical dust receiving chamber 22 as a dust receiving part for receiving dust, and an upper lid 5 (including the outer cylinder 3 and the casing 2) including the suction port 7. An annular part surrounded by the peripheral wall of the casing 2, the outer cylinder 3, the inner cylinder 4 (part not facing the outer cylinder 3), and the bottom wall 6 (the inner cylinder 4 and the casing 2). Water storage as a cylindrical water storage section. It has been the chamber 23.
[0025]
Next, the dust collection operation of the wet dust collector 1 will be described. In the wet dust collector 1, first, water is stored in the water storage chamber 23 in advance. In order to store water, the drain valve 11 is closed and the water supply valve 9 is opened. Then, since water is supplied from the water supply pipe 9 to the water storage chamber 23, the dust receiving chamber 22 is immersed in the supplied water, and then the water level rises to the extent that the upstream circulation pipe 10 is filled. Then, the water supply valve 9 is closed. Thereby, water is stored in the water storage chamber 23 to such an extent that a space where the water storage chamber 23 and the dust receiving chamber 22 communicate with each other can be formed by a suction operation of the vacuum cleaner 16 described later.
[0026]
Next, the liquid feed pump 24 is driven. Then, the water in the water storage chamber 23 is circulated by the liquid feeding operation of the liquid feeding pump 24. That is, the water fed from the liquid supply pump 24 is flowed from the downstream circulation pipe 20 to the outlet chamber 21, it is sent toward the lower end portion of the flow exits chamber 21 to the outlet 19 of the upper portion. Thereafter, the water flowing out from the outlet 21 flows down along the outer peripheral wall of the inner cylinder 4 as shown in FIG. 2 in a state where the cleaner 16 is not driven. The water that has flowed down is temporarily retained in the water storage chamber 23, and then sent from the upstream circulation pipe 10 to the liquid feed pump 24, and is sent from the liquid feed pump 24 to the downstream circulation pipe 20 again.
[0027]
Then, the cleaner 16 is driven. Then, the water storage chamber 23 is sucked from the suction port 7 through the suction pipe 14 by the suction operation of the cleaner 16, so that the water in the water storage chamber 23 rises along the inner wall of the casing 2 (in FIG. 1). A space in which the water storage chamber 23 and the dust receiving chamber 22 communicate with each other is formed, whereby the inside of the dust receiving chamber 22 is sucked from the lower end through the communication port 18, and the dust receiving chamber Since the inside of 22 has a negative pressure and the dust generation source 17 is sucked from the dust supply port 13 via the dust supply pipe 15, the dust is pneumatically transported from the dust generation source 17 via the dust supply pipe 15. (Suction transportation) and the dust is supplied from the dust supply port 13 into the dust receiving chamber 22.
[0028]
Then, since dust is supplied downward from the dust supply port 13 together with air into the dust receiving chamber 22 which is set to a negative pressure, as shown in FIG. 3, the supply pressure P2 to which the dust is supplied is used. The liquid supply of the liquid supply pump 24 from the outflow port 19 that is opposed to the dust supply port 13 and the air that is supplied from the dust supply port 13 with an interval that presses the water that flows out from the outflow port 19. The water flowing out by the pressure P1 is pressed, and the water flowing out from the outflow port 19 is ejected so as to be spouted and spread upward. As a result, the dust received in the dust receiving chamber 22 is efficiently absorbed in contact with the water droplets that have become fine (fog-like) due to the fountain-like jetting. Dust is achieved.
[0029]
Thereafter, water contact absorbed dust, between the outer tube 3 (the peripheral side wall of the powder dust receiving portion) and the inner cylinder 4 (the peripheral side wall of the outflow section) is well dust collecting while falling with water . Then, at this time, the powder dust receiving chamber 22, because it is sucked from the suction pipe 14 by the cleaner 16 via the water storage chamber 23 from its lower end, the powder dust receiving chamber 22, the outer tube 3 Since an air flow that flows around the inner peripheral wall and the outer peripheral wall of the inner cylinder 4 is generated, the dust contacts the fine water droplets in an opposing manner, and then, along with the air flow, along with the water, for example, spirally Since dust is collected well while falling, more efficient dust collection can be achieved.
[0030]
Then, dust which has fallen to the lower end of the powder dust receiving chamber 22 is moved from its lower end to the water storage chamber 23 via the communicating port 18 at its water reservoir 23, a bottom wall provided on inclined 6 Therefore, it can be appropriately removed from the drain pipe 8 by opening / closing operation of the drain valve 11. In addition, what is necessary is just to supply the water shortage by the waste_water | drain from the water supply pipe 9 suitably by the opening / closing operation | movement of the water supply valve 12. FIG. The water-insoluble powder floats in the form of bubbles on the water surface in the water storage chamber 23.
[0031]
Further, after the ejection, it has fallen to the lower end of the powder dust receiving chamber 22 water droplets moves from its lower end to the water storage chamber 23 via the communication port 18, the water storage chamber 23, the driving of the liquid supply pump 24 Thus, it is sent again to the lower end of the flowing water chamber 21. Therefore, it is possible to efficiently circulate the water in the water storage chamber 23 and achieve efficient dust collection.
[0032]
And in such a wet dust collector 1, in the state which made the inside of the dust receiving chamber 22 into the negative pressure, the water which flows out from the outflow port 19 is simply ejected in the shape of a fountain with the supply pressure P2 of dust. Because it is a configuration, it is not necessary to equip a sprayer for spraying water or a stirring blade (water turbine) for colliding water droplets, and the compact configuration makes it compact, lightweight, and portable. It can be easily carried to the site where you want to collect dust.
[0033]
Therefore, this wet dust collector 1 is only carried to the site and connected to the vacuum cleaner 16 when collecting a bulky crushed material generated at the time of crushing a building wall material, for example, at a construction site. Thus, simple and efficient dust collection can be achieved.
[0034]
In this wet dust collector 1, the outlet 19 is formed in a saw-tooth shape (jagged shape), for example, as shown in FIG. 4, or in a spiral shape, as shown in FIG. Also, the water can be ejected in a fountain state.
[0035]
Moreover, if the casing 2, the outer cylinder 3, and the inner cylinder 4 are formed of, for example, a transparent acrylic plate, the outflow state of water inside the apparatus can be confirmed.
[0036]
In the above description, the water storage chamber 23 has been formed as an inner space of the tubular (cylindrical), but in no way limited to its shape, for example, may be a rectangular tube.
[0037]
In the above description, the vacuum cleaner 16 is connected to the suction pipe 14, but the suction means is not particularly limited, and for example, a suction type blower may be connected.
[0038]
【The invention's effect】
As described above, according to the first aspect of the present invention, it is possible to reduce the size, improve the weight and improve the portability of the compact configuration, and easily carry it to the site where dust collection is desired.
[0039]
Moreover, the dust received in the dust receiving part and the water sprayed can be made to contact efficiently, and efficient dust collection can be achieved.
[0040]
Moreover , dust is collected well together with water droplets while falling between the peripheral side wall (outer cylinder) of the dust receiving part and the peripheral side wall (inner cylinder) of the outflow part. Therefore, more efficient dust collection can be achieved.
[0041]
In addition , more efficient dust collection can be achieved, and the collected dust can be well stored in the water storage unit.
[0042]
