(Points of interest)
As shown in FIG. 8, the wet dust collector 1 is provided with a horizontal exhaust air inlet (connection port flange) 25 at the central height of the left and right widths of the back surface 20 of the dust collector body 10 and the dust collecting chamber 2. The shower nozzle 3 having a liquid tank 4 and extending from the submersible pump 30 submerged in the liquid tank 4 storing the dust collection liquid 40 is arranged near the center of the exhaust air horizontal inlet 25 and the injection port thereof While being fixed in a horizontal posture toward the inside of the dust collection chamber 2, the top surface 22 extends between the rising exhaust port 26 opened from the upper end of the front surface 21 of the dust collection chamber 2 to the front end of the top surface 22 and the rear surface 20. It consists of a curved plate that hangs down and faces the exhaust air horizontal inlet 25 and the shower nozzle 3, and has an exhaust gap 61 between the liquid draining end 60, which is the lower end edge thereof, and the liquid tank 4 dust collection liquid 40 liquid level 41. Further, there is an exhaust gap 61 between the back of the curved plate and the inner wall 21 in front of the dust collection chamber 2. The downflow guide wall 6 is provided so as to secure the ascending exhaust passage 27 connecting the ascending exhaust port 26, and as shown in FIG. 7, the exhaust duct derived from the cereal dryer (exhaust source) 7 (Duct hose) 70 is connected to the exhaust wind horizontal inlet (connecting port flange) 25 of the dust collector 1, and the exhaust air 8 from the grain dryer 7 is introduced into the exhaust wind horizontal inlet 25. The shower nozzle 3 continuously injects the supplied dust collection liquid 40 in a horizontal conical shape toward the downflow guide wall 6 in the dust collection chamber 2, and causes the dust collection liquid 40 to adhere to the dust 9 in the exhaust air 8. Then, the dust collecting liquid 40 dropped and collected in the liquid tank 4 and attached with the dust 9 sprayed on the downflow guide wall 6 is transferred to the liquid tank 4 from the drain end 60 along the downflow guide wall 6. -It is assumed that it is recovered and further passes through the exhaust gap 61 and rises through the exhaust passage 2 The dust 9 and the dust collecting liquid 40 are dropped and collected in the process of ascending, and the purified exhaust air 8 is discharged through the rising exhaust port 26. The dust collecting liquid 40 ejected from the shower nozzle 3 is a liquid tank. In order to collect more dust 9 before dropping to 4, the height H of the exhaust air horizontal inlet 25 should be set as high as possible.

    However, as shown in FIG. 7, the exhaust duct 70 of the grain dryer 7 is generally derived from a low position due to its structure, and the height difference h from the exhaust exhaust horizontal inlet 25 of the dust collector 1 is h. The duct hose 70 must be bent and connected, and as shown in FIG. 7, if the duct hose 70 is bent at a steep angle, the dust 9 is clogged or the exhaust air pressure is increased. Since various problems may occur and normal operation of the grain dryer 7 may not be obtained, a sufficient distance should be secured between the grain dryer 7 and the dust collector 1 and bent at a gentle angle as possible. As a result, it is difficult to install in a small space, and if it must be installed in a limited space, as shown in FIG. Scoop the ground The dust collector 1 is installed in this hole and the horizontal duct hose 70 is connected to the grain dryer 7 after being dug down by the height difference (h in FIG. 7). In addition to increasing the labor burden on the operator, the installation work in the hole may cause a heavy work load that rainwater easily enters the hole and pumps up the accumulated rainwater. 7 and 8, when the exhaust air horizontal inlet 25 of the dust collector 1 is installed at a position higher than the exhaust duct 70 of the grain dryer 7, the dust collection sprayed from the shower nozzle 3 is used. A part of the liquid 40 may flow backward in the low exhaust duct 70 and the cereal dryer 7 may enter the crocodile, which may adversely affect the normal operation of the cereal dryer 7.

(Conventional technology)
Reflecting this situation, proposals that can be used to overcome this situation are not unheard of.
For example, as typified by those proposed in the following Patent Documents 1 (1) to (4), a dust collector can be downsized and simplified, and the exhaust air inlet can be set at a low position. Although it is often seen, even if it is downsized in this way, it has a vertical exhaust air inlet as in Patent Documents 1 (1) and (3), and it is an exhaust duct from a grain dryer. As shown in Patent Documents 1 (2) and 4 (4), the dust collection chamber and the bag body for dust collection can be simplified by following the exhaust duct. Therefore, there remains a problem that a sufficient dust collection effect cannot be obtained unless the shape is horizontally long. Therefore, all the conventional dust collectors bend the exhaust duct from the grain dryer at a steep angle. Or connect the dust collection chamber to the exhaust duct Modeled and was supposed to have a fatal defect that must be set long.

(Awareness of problems)
As described above, the various dust collectors proposed so far must bend the exhaust duct from the grain dryer 90 ° so that the exhaust air is supplied vertically to the liquid level for dust collection. All conflicting issues such as downsizing, simplification, high quietness, and high dust collection performance, such as a long dust collection chamber in the horizontal direction to extend the exhaust duct, Moreover, there is no dust collector that can easily connect the horizontal exhaust duct from the grain dryer and reliably prevent the backflow of the dust collecting liquid to the grain dryer. The user of the machine has solved any shortcomings with his own efforts and contrivances until now, or he meditated on such shortcomings and praised it as unavoidable. Deal with problems and put up with such annoyance Because not only it was the actual situation.

Judging from whether it is possible to develop a new dust collection technology that can be easily connected in a substantially horizontal state without bending at an angle, we started its development and research very quickly, and trial and error over a long period of time. As a result of repeating many trial manufactures and experiments, this time, we finally succeeded in realizing a dust collector with a novel structure. In the following, the configuration of the dust collector will be described together with an embodiment representative of the present invention shown in the drawings. It will be described in detail.

(Structure of the invention)

    If the dust collector consisting of this basic configuration is shown as a more specific one, a horizontal exhaust outlet that can be connected to an exhaust source at an appropriate height position on the back of the sealed dust collection chamber, In the opposite upper part of the front or top of the top, the rising exhaust port and the liquid tank that stores the collected liquid at a constant liquid level over the entire floor of the bottom are provided as the dust collector body. A shower nozzle capable of spraying the pressure fluid guided from the installed pump in a conical shape is arranged near the center of the horizontal exhaust inlet, and supported in a substantially horizontal posture so that the inner wall of the dust collection chamber faces toward the side. In addition, a reflection leap wall is provided in an appropriate range that is below the center of the cone-shaped injection shape of the shower nozzle in the dust collection chamber, and the front inner wall of the dust collection chamber and the reflection leap wall In between, there is a liquid cutting end that is suspended from the top surface and has a clearance for exhaust between the liquid surface of the liquid tank Pressure fluid and exhaust air that are at least above the center of the cone-shaped injection shape of the shower nozzle and below and below the center of the cone-shaped injection shape of the shower nozzle and are reflected and raised by the reflection jumping wall Is provided with a downflow guide wall having an appropriate vertical cross-sectional shape capable of securing an ascending exhaust passage connecting the gap between the exhaust and the ascending exhaust port to the front inner wall of the dust collection chamber over the range of Becomes a dust collector.

    In other words, the horizontal exhaust outlet that can be connected to the exhaust source at the appropriate height of the rear of the sealed dust collection chamber, the upper front or ceiling that is opposite to the rear A rising exhaust port at the appropriate position in front of the surface and a liquid tank storing dust collection liquid at a constant liquid level over the entire bottom floor are provided as a dust collector body, and the pressure liquid led from the pump provided in the liquid tank is drilled. The shower nozzle that can be sprayed in a shape is arranged in the vicinity of the center of the horizontal exhaust air inlet, and is supported in a substantially horizontal posture so that the front inner wall of the dust collection chamber faces toward the side, and the shower nozzle in the dust collection chamber In addition, a reflective leap wall is provided in an appropriate range below the center of the cone-shaped jet shape, and the space between the front inner wall of the dust collection chamber and the reflective leap wall is suspended from the top surface. And a liquid drain end that secures an exhaust gap between the liquid level of the liquid tank and at least the cone-shaped spray of the shower nozzle. Dust collection over the range above the center of the shape and the range below the center of the cone-shaped injection shape of the shower nozzle and reaching the reflected and rising pressure liquid and exhaust air. A downward flow guide wall having an appropriate vertical cross-sectional shape capable of securing an ascending exhaust path connecting the exhaust gap to the ascending exhaust port is provided between the interior wall of the room and the cone-shaped jet liquid ejected from the shower nozzle. At the center of the cone-shaped jet shape, the jet liquid that adheres to the dust mixed in the exhaust air flowing in through the horizontal wind inlet, and the jet liquid that collides with the reflection leap wall reflects and rises to extend the fall and dwell time. The upper spray cone is mixed with the lower spray jet from the center of the cone spray shape, and the adhesion of dust and liquid scattered in the exhaust air is promoted evenly. It shall be guided to the upper part of the downflow guide wall, and the liquid containing dust will Falling down and adhering to the downflow guide wall and flowing down to the liquid tank, the purified exhaust gas is further purified in the process of passing through the exhaust gap and the ascending exhaust path below the drainage end of the downflow guide wall, and through the ascending exhaust port It can be said that the dust collector has a configuration that can be discharged to the outside.

    More specifically, the exhaust air source is located at the height of the center of the rear left and right width of the dust collection chamber, which is sealed with a predetermined volume, at the height that coincides with the end of the exhaust duct / duct hose horizontally guided from the exhaust air source. Exhaust horizontal inflow inlet with a connection flange that can connect the end of the exhaust duct and duct hose induced from the air, and a rising exhaust outlet at a suitable position in the upper part of the front or the front of the top opposite the rear And a shower nozzle capable of injecting the pressure liquid led from the pump provided in the liquid tank in a conical shape by providing a liquid tank storing dust collection liquid at a constant liquid level over the entire bottom floor. , Arranged near the center of the exhaust air horizontal inlet, and supported in a substantially horizontal posture so that the inner wall of the dust collection chamber faces toward the side, and from the center of the conical injection shape of the shower nozzle in the dust collection chamber Reflective leap walls are provided in the appropriate range where the bottom is Above, between the front inner wall of the dust collection chamber and the reflection leap wall, has a liquid cut end that is suspended from the top surface and has an exhaust gap between the liquid surface and the liquid surface.

Thus, the dust collector has a configuration in which a downflow guide wall capable of securing an ascending exhaust passage connecting the ascending exhaust port is provided.

    As described above, according to the dust collector of the present invention, unlike the conventional one, the exhaust gas discharged from the exhaust source and blown into the dust collecting chamber through the exhaust exhaust horizontal inlet from the unique characteristic configuration as described above. Since the reflection leap wall reflects and guides the wind and the component of the dust collection liquid sprayed from the shower nozzle into a cone-shaped spray shape that is downward from the horizontal, the exhaust wind is horizontal. Extending the dwell time of all the exhaust air and dust collection liquid blown into the dust collection chamber through the inlet and shower nozzle, increasing the chance that the dust contained in the exhaust air will come into contact with and adhere to the dust collection liquid. , More dust can be separated and removed from the exhaust air, and the height dimension from the liquid level to the exhaust air horizontal inlet can be shortened accordingly. Up the exhaust duct derived from the position It must be bent and connected to the horizontal exhaust outlet, and it is difficult to install in a narrow space, which may cause various problems such as backflow of dust collection liquid to the exhaust source. Resolve these problems and make it possible to connect the exhaust duct in a horizontal position without bending it at a steep angle even in a narrow space, and reliably prevent the backflow of the dust collection liquid to the exhaust air source. In addition, the dust collector body can be greatly reduced in size, and the excellent characteristics that the dust collection performance can be equal to or higher than that of conventional products can be obtained. .

    In addition, the downflow guide wall blocks the exhaust air and dust collection liquid that has flowed into the dust collection chamber through the exhaust air horizontal inlet and shower nozzle, and prevents them from being quickly discharged from the ascending exhaust port. Then, it is assumed that a large amount of dust collection liquid and dust adhering thereto are caught and flowed down and fall into the liquid tank, bypass the liquid drain end, and are guided to the rising exhaust path through the exhaust gap. Dust remaining in the exhaust air in the process of ascending the ascending exhaust passage can be dropped and removed by its own weight, and can be cleaned more efficiently, and only clean air can be exhausted from the ascending exhaust port. It has an excellent effect of being able to do it.

    The reflection jumping wall is close to the exhaust wind horizontal inlet and the shower nozzle, and the dust discharge outlet is opened near the lowest end of the reflection jumping wall. Dust, dust collection liquid, and mixed liquid adhering to the upper surface of the lifting wall can naturally flow and / or fall into the liquid tank through the dust liquid discharge port, and the upper surface of the reflective jumping wall is always clean and smooth. Therefore, it is possible to stably secure high reflection performance and to stabilize and maintain a higher cleaning effect.

    A plane with a constant climbing slope where the rebound wall rises linearly from the vicinity of the top wall near the exhaust outlet horizontal inlet and the shower nozzle to the vicinity of the edge near the downflow guide wall. It is possible to easily manufacture the reflective leap wall from a flat or block-shaped material, which is excellent in productivity and can be provided at a low price. From the vicinity of the end close to the exhaust air horizontal inlet and the shower nozzle to the vicinity of the end close to the downflow guide wall, or a plurality of bending planes formed by combining a plurality of climbing gradients that rise linearly The one that is set to any one of the bent flat shapes having the folds of the light is reflected and guided at an angle gradually approaching vertically upward as it moves away from the horizontal exhaust inlet and shower nozzle. And jet collection Cross-intricate shaped mixing liquid, and more complex, the effect is obtained that it becomes possible to adhere and remove many more dust dust collecting liquid.

    Furthermore, the reflection leap wall has a primary curved surface whose upper wall surface rises with a constant curvature from the vicinity of the end close to the exhaust wind horizontal inlet and the shower nozzle to the vicinity of the end close to the downflow guide wall. A quadratic curve that rises with its curvature gradually changing from the vicinity of the end close to the exhaust wind horizontal inlet and shower nozzle to the vicinity of the end close to the downflow guide wall. Even in the case where the shape is set, the crossover / complex mixing of the exhaust air and the dust collection liquid is further promoted evenly according to the change in the curvature so that the dust can be collected more efficiently. be able to.

    Exhaust air that flows in from the horizontal exhaust air inlet along the left and right edges separated from the center between the left and right edges where the reflective jump wall coincides with the center of the shower nozzle, and the dust collection liquid that is ejected from the shower nozzle The rectifying blade tip of an appropriate shape can be erected so that it can be guided so as to be held within the right and left width of the reflection leap wall, or either the left and right edges are either the dust collection chamber top wall or the same left and right wall The upper wall of the reflective jumping wall scatters the exhausted air and the liquid collected from the horizontal air inlet and the shower nozzle into the dust chamber without escaping in the left-right direction. And the dust collection chamber top wall surface, the exhaust wind descends quickly and reliably prevents the exhaust air from going to the ascending exhaust passage through the exhaust gap, and sprayed from the shower nozzle. Prevents the dust collection liquid from quickly falling into the liquid tank. To, may be those to catch more dust dust collection fluid greatly enhance the purification performance.

In implementing the present invention having the above-described configuration, the best or desirable mode will be described.

As shown in the figure, the metal frame installed on the liquid tank has a synthetic resin waterproof It can be made with stretched the over door.

    The horizontal exhaust inlet has a function to connect an exhaust duct extending from the exhaust source so that the exhaust from the exhaust source can be introduced into the dust collection chamber, and a shower is provided near the center of the inlet. The nozzle must be displaceable, the exhaust duct should be airtight and detachably connectable, and the shower nozzle can be fixedly supported in the specified direction near the center of the inlet It is desirable to use a metal connection flange having sufficient strength and water resistance, as shown in the examples described later.

The ascending exhaust port has a function of ascending the ascending exhaust passage in the dust collecting chamber and enabling the exhaust gas that has been purified to be smoothly discharged out of the dust collecting chamber, and can be an opening without any obstacles. Outside, a dust collection filter or a waterproof / breathable membrane can be attached.
On the other hand, the ascending exhaust channel flows into the dust collection chamber through the exhaust wind horizontal inlet, guides the exhaust wind induced by the reflection leap wall and the descending flow guide wall toward the ascending exhaust port, and In the ascending process, it shares the function of allowing dust and collected liquid remaining in the exhaust air to fall and be removed by its own weight, such as dust and collected liquid. Sufficient air-tightness must be secured to prevent dust, dust collection liquid, etc. from leaking out of the dust collection chamber, and a volume that can be exhausted by reducing the pressure sufficiently so as not to generate noise due to exhaust. It is desirable that the inner wall should be as rough and smooth as possible to facilitate smooth and quiet exhausting, but it is possible to reduce the pressure and silence by providing a detour or installing a noise-reducing wall.

For example, the injection shape may be conical, triangular pyramid, quadrangular pyramid, The above polygonal pyramid shape can be used.

    The liquid tank is capable of storing an appropriate amount of dust collection liquid at the bottom of the dust collection chamber, and in the process of injecting the dust collection liquid toward the exhausted air guided into the dust collection chamber, the liquid tank that contains dust and falls. This function is used to store the dust liquid and to collect the dust in the stored dust collection liquid so that it can be collected in a deposited state, and it must be sufficiently waterproof to prevent the stored dust collection liquid from leaking outside. It must be possible to discharge a certain amount of dust collection liquid, and if a certain amount of new dust collection liquid is supplied, a considerable amount of used dust collection liquid can be automatically discharged. In addition, as shown in the examples to be described later, a pump capable of supplying dust collection liquid of a predetermined pressure to the shower nozzle can be provided at an appropriate place so that the dust collection liquid can be circulated and collected. The dust liquid should be a solution containing a surfactant or other chemicals to enhance dust collection. Door While it is possible, when considering the impact on the economy and the environment, it is preferable to directly utilize such as tap water or other water purification.

    The pump has a function to enable the dust collection liquid of a predetermined pressure to be supplied to the shower nozzle, and can continuously supply the dust collection liquid while the exhaust air flows from the horizontal exhaust air inlet. It is necessary to connect the inflow part to either a new dust collection liquid supply source or a liquid tank, and connect the outflow part to a shower nozzle. As shown in the examples, the submersible pump can be incorporated by being immersed in a suitable place in the liquid tank.

    The reflection jumping wall can be guided to reflect upward both the dust collection liquid sprayed from the shower nozzle into the dust collection chamber and the exhaust air flowing into the dust collection chamber from the exhaust wind horizontal inlet. It must be provided in an appropriate range between the exhaust air horizontal inlet and shower nozzle and the downflow guide wall and below the center of the conical jet shape of the shower nozzle. Instead, it should have a wall shape or plate shape that is inclined so that the jet dust collection liquid and the exhausted air are reflected and guided obliquely upward.

Dust 9 can be collected.

    The dust 9 and the dust collecting liquid 40 adhering to the upper wall surface 50 of the reflection leap wall 5 flow down along the upper wall surface 50 due to their own weight, and drop and drop into the liquid tank 4 through the dust liquid discharge port 53. 50 can always maintain a state in which a smooth surface can be exhibited with a smooth surface exposed.

    The dust 9 adsorbed by the dust collection liquid 40 is sprayed onto the vertical flow guide wall 6 having an arc-shaped longitudinal section disposed in the range to be a flight destination, and is dropped and dropped onto the liquid tank 4 from the liquid draining end 60. A thing that falls and rises along the arc-shaped wall surface of the downflow guide wall 6 and soars in a mist-like or floating state is free-falling into the liquid tank 4 by its own weight of the dust collection liquid 40 Thus, most of the dust 9 contained in the exhaust air 8 is separated and dropped until it passes through the exhaust gap 61, and is accumulated and recovered in the liquid tank 4 in the form of precipitates and deposits. Further, even in the process of passing through the exhaust gap 61 and ascending the rising exhaust passage 27, the dust 9 adsorbed by the dust collection liquid 40 and the dust 9 not adsorbed by the dust collection liquid 40 are liquidated by their own weight. Dust 9 falling in the tank 4 and remaining in the exhaust air 8 passing through the rising exhaust port 26 And anti-dust filter 26 is removed, becomes the exhaust air only was almost completely cleaned out dust collector body 10.

    By providing the reflection jumping wall 5, the exhaust air 8 blown into the dust collection chamber 2 from the connection port flange 25 and the dust collection liquid 40 ejected by the shower nozzle 3 are all directed upward above the horizontal. It can be blown up, and the time for floating and confusion in the air is extended, the chance of the dust collection liquid 40 adsorbing to the dust 9 is greatly increased, and the purification performance equal to or higher than that of the conventional product can be achieved. In addition, as shown in FIGS. 3 and 4, the height difference h can be set, and the exhaust duct (duct hose) 70 of the grain dryer 7 (exhaust source) can be connected in a horizontal position. be able to.

    In addition, as shown in FIG. 5 and FIG. 6, the shape of the upper wall surface 50 of the reflection leap wall 5 with an increasing rate (gradient change rate) from the lower end 51 toward the upper end 52 is the base end. The direction of reflection gradually changes from the edge to the edge, and it is possible to realize a more versatile and versatile crossover of the dust collection liquid 40, the exhaust air 8 and the dust 9, so that the dust collection liquid 40 can be applied to the dust 9. Adhesion opportunities can be greatly increased, and the dust collection rate can be greatly increased.
