[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The dust collecting apparatus of the present invention performs centrifugal dust collection by introducing a dust-containing gas along an inner surface of a side wall of a housing, for example, tangentially to an inner surface of a cylindrical portion.
The collected dust particles are collected downward, and the clean gas from which the dust particles have been separated is guided to an inner cylindrical portion connected to a clean gas outflow opening provided at the center of the ceiling of the housing cylindrical portion, It is formed so that it can flow out of the clean gas outflow opening. As such a dust collector, a so-called
The housing can be formed in a cyclone type, and the housing can be formed in a cyclone structure further having a conical dust collection particle collecting portion constricted below the cylindrical portion.
In the present invention, a clean gas outflow opening is provided in the housing ceiling. The clean gas outflow opening is provided with an inner cylindrical portion, which is connected to the upper end thereof and has a structure that reduces pressure loss, and is suspended downward in the housing. An exhaust gas introduction opening is provided in the side wall of the housing with the opening directed tangentially to the side wall. The exhaust gas introduction opening is, for example, a grain drying preparation facility or a grain receiving facility. , A hulling facility, a grain roughing machine, a grain drying device, a grain preparation processing facility, a grain drying preparation storage facility or other grain processing facility, or one of the classified product outlets of a classifier connected to the exhaust pipe. It can be connected and can be used for cleaning dust-containing gas discharged from the exhaust pipes of those facilities.

In the present invention, only air is allowed to flow out to at least one of the side wall portion of the housing and the lower end of the inner cylindrical portion without causing the dust particles of the dust-containing gas to flow out as much as possible. Is provided with a filter cloth portion formed of a filter cloth member such as a filter cloth usually used for a canvas or a bag filter. The filter cloth part, that is, the filter cloth part of the side wall part or the inner cylinder part, or the filter cloth part of both the side wall part and the inner cylinder part has a size of dust particles in the dust-containing gas to be collected. Can be formed with a filter cloth whose pore size is adjusted appropriately. If the size of the pores of the filter cloth is made large enough to prevent dust from leaking, the dust-containing gas does not flow out of the housing through the filter cloth part of the housing to the outside of the housing, and the dust-containing gas flows into the inner cylinder. It is possible to increase the amount of clean air that has been filtered through the filter cloth portion of the inner cylindrical portion without escaping the dust particles, and to increase the amount of dust-containing gas processed in the housing. By adjusting the amount of clean air flowing out of each filter cloth portion, the dust concentration in the dust gas can be adjusted by the adjusted amount, and the swirl flow velocity of the dust-containing gas is adjusted. It is possible to adjust the separation efficiency and dust collection efficiency of the dust particles of the dust-containing gas.

In the present invention, the lower part of the inner cylinder portion includes
For example, the lower end opening of the inner cylinder portion is blocked so that the rising gas flowing from the bottom wall portion toward the inside of the inner cylinder portion flows in from below and the dust collection particles are prevented from directly entering the inner cylinder portion. A baffle plate of a size to cover is provided in the horizontal direction. In the present invention, since the baffle plate is provided as described above, even if a part of the dust particles settled and separated and stored in the dust particle collecting portion at the bottom of the housing is accompanied by the rising gas flow, the rising Before the gas is introduced into the inner cylinder, the gas impinges on the baffle plate located below the entrance and most of the accompanying dust particles are separated, so that the stored dust particles directly enter the inner cylinder. It can be unaccompanied.

Further, in the present invention, the swirling gas flow flowing into the inner cylindrical portion is subjected to so-called inertial dust collection in order to collect dust by losing inertia of dust particles in the swirling gas flow. A rectifying plate portion may be provided, for example, by a partition plate member or the like in front of the turning direction so that the swirling gas flow flowing into the cylindrical portion is blocked in the flow path. When the rectifying plate portion is provided in this manner, the swirling gas flow of the dust-containing gas collides with the rectifying plate portion to form a gas flow flowing uniformly upward, and relatively fine dust particles in the dust-containing gas. Is settled and flows into the inner cylinder portion. In the present invention, one or more plate members are provided extending in a direction crossing the inside of the inner cylinder or radially outward from the axis of the inner cylinder. When providing two or more current plate members, the plate member,
They can be provided crossing each other in a cross shape or the like. In the present invention, a dust particle collection unit is formed below the plate member of the current plate unit.

In the present invention, when the lower portion of the side wall portion of the housing is formed in an inverted conical shape which is narrowed downward,
The collected particles settle and collect at the bottom of the inverted conical shape at the bottom of the housing, and the lower end of the inverted conical portion where the collected particles are collected accompanies the gas flow flowing upward from the lower end of the inner cylinder. If it is located far from the lower end of the inner cylindrical portion, the entrainment of the collected particles is less likely to occur, so that it is not necessary to provide a baffle plate at the lower end of the current plate.
However, in the case of an inverted conical shape having a shallow bottom, trapped particles are likely to be accompanied, so that it is necessary to provide a baffle plate at the lower end of the current plate. In the present invention, a filter cloth portion for filtering and flowing out clean air can be formed also on the upper portion of the inverted conical portion of the dust collecting particle collecting portion.

In the dust collector of the present invention, in order to reduce the size and weight of the dust collector and facilitate transportation, the housing is foldable, for example, a flexible sheet material made of canvas or up to 10 μm. Can be made of a sheet material made of a filter cloth capable of filtering particles of, for example, a nylon woven fabric for water filtration. Such a housing made of a flexible sheet material made of cloth is used by being suspended because it cannot maintain its shape due to its own weight. Thus, the flexible sheet material used for the housing is made of a poorly breathable cloth with a gas filtration function, which has sufficient tensile strength and other mechanical strength so that it can support its own weight with tension when suspended. Preferably, the sheet material is In the present invention, instead of the flexible sheet material made of canvas, it can be made of a flexible sheet material or a film material made of a foldable flexible plastic fiber or a plastic material. As such a flexible sheet material, for example, a sheet made of a plastic material such as vinyl, polyethylene, or polypropylene, or a cloth or film coated with a plastic film is used.

In the present invention, the cross section or the end face of the housing can be formed in a polygonal shape such as a quadrangle or a circle. In order to form the housing in such a shape, a wire made of, for example, steel or plastic material is formed around a bottom wall and / or a ceiling of the housing to maintain a predetermined end surface or cross-sectional shape. Or the frame member etc.
Preferably, it is attached via a guide or by sewing. When the wire is provided via the guide, the circle can be easily formed by passing the steel wire or the like through the tubular guide when the folded housing is opened and assembled.

In the present invention, the plate member of the rectifying plate portion and the baffle plate member of the baffle plate portion are also made of a material which is flexible so as to be foldable.
For example, it can be formed of a flexible sheet material made of canvas, plastic fiber or plastic material. In the present invention, the baffle plate portion is formed in a disk shape, and a steel or plastic wire or frame member is detachably held at a peripheral edge thereof. The peripheral portion of the baffle plate can be easily formed into a planar shape such as a polygon or a circle by the elasticity or rigidity of the retained steel or plastic wire or frame member. . If the plane shape of the baffle plate portion is, for example, circular, the periphery of the rectification plate portion connected to the baffle plate portion will be pulled outward by, for example, the elasticity of the wire rod during assembly, and through the rectification plate portion. The cross-sectional shape of the inner cylinder can be kept substantially circular, and the maintenance of the shape of the inner cylinder is simple and easy.

In the present invention, the dust collecting device is provided with at least one dust-containing gas introduction opening in the side wall of the housing. A dust-containing gas introduction pipe is connected to the dust-containing gas introduction opening, and the dust-containing gas introduction pipe is provided along the inner wall of the housing, for example, in a tangential direction with respect to the inner surface of the cylinder of the cylindrical housing. Is preferred. In this case, the dust-containing gas introduction pipe can be provided below or above the lower end of the inner cylinder. When the dust-containing gas inlet is provided above the lower end of the inner cylindrical portion, the dust-containing gas flow rate is relatively large.In this case, a hollow cylindrical filter cloth portion is connected to the lower end of the inner cylindrical portion. It is preferable to provide it. However, the lower end portion of the extended filter cloth portion of the inner cylindrical portion is provided above and separated from the dust collection particle collecting portion so as not to bring dust collection particles from the dust collection particle collecting portion.

The case where the dust-containing gas introduction port is provided below the lower end of the inner cylinder portion is when the flow rate of the dust-containing gas is relatively small, and the dust-containing gas introduction pipe is provided below the lower end of the inner cylinder portion. However, the dust-containing gas inlet pipe is provided above the dust-collecting particle collecting section so that the dust-collected particles collected from the dust-collecting particle collecting section by the introduced dust-containing gas are not brought in. Can be In this case, a filter cloth part may be provided at the lower end of the inner cylinder part. However, unless the dust particles to be separated by the swirling gas flow are brought into the inner cylinder part, it is particularly necessary to provide the filter cloth part. There is no. Even in this case,
The lower end opening of the inner cylindrical portion is provided above the dust collecting portion so as to prevent dust particles from being brought in from the dust collecting portion, and is provided below the lower end opening of the inner cylindrical portion. Preferably, a baffle plate is formed. In this case, the position of the baffle plate portion provided at the lower end of the inner cylinder portion is at a high position that is separated from at least one dust-containing gas introduction opening by a distance at which dust particles introduced from the introduction opening can be separated. Is preferably provided.

When a plurality of dust-containing gas introduction openings are provided, a dust-containing gas introduction pipe for a high-flow-rate dust-containing gas is connected to the upper part, and an introduction pipe for a relatively low-flow-rate dust-containing gas is connected to the lower part. Connecting. On the housing upper side wall,
It can be formed in the shape of a hollow truncated pyramid that forms an enlarged portion whose cross-sectional area is increased downward to a location below the upper dust-containing gas inlet. Providing a side wall that increases its diameter downward at the top of the housing in this way,
Even when an exhaust gas having a relatively high dust concentration and a high flow velocity is introduced, the flow velocity and the dust concentration can be reduced, which is preferable from the viewpoint of increasing the efficiency of separating fine particles and avoiding pressure loss. Further, even when the upper side wall is provided in a shape such as a hollow truncated cone, at least a part of the lower part is
It can be a filter cloth part formed of a filter cloth member. This is preferable because even if exhaust gas having a high dust concentration and a high flow velocity is introduced, the flow velocity and the dust concentration can be reduced and a pressure loss can be avoided. In the present invention, even in the case of a dust-containing gas flow having a relatively large flow velocity, when the capacity of the housing is large, the linear velocity in the housing can be reduced. In addition, a dust-containing gas introduction opening can be provided.

In the present invention, the housing is suspended from above by a hanging tool or the like and supported to form a dust collection chamber in the housing. For this purpose, the housing is provided with, for example, a hanging member engaging portion at the ceiling, particularly near the clean gas outlet, and a hanging member or the like supported by the supporting member at the hanging member engaging portion. By engaging the members,
The housing is suspended from the suspension member. The hanging member engaging portion can be attached to the housing by sewing or a fastener such as a fastener. In the present invention, the upper part of the ceiling of the housing can be covered with a filter cloth in order to prevent particles to be separated from being mixed into the clean gas and being released to the atmosphere.

According to the present invention, there is provided a ceiling partly formed with a clean gas outflow opening part, and an upper end part connected to an outer peripheral part of the ceiling part, and a dust-containing gas introduction opening partly provided at least in part. A housing having a formed side wall portion is provided, and in the housing, an upper end portion is connected to a clean gas outflow opening portion of a ceiling portion of the housing, and a hollow cylindrical shape hanging from the upper end portion. An inner cylinder portion, comprising a dust collection particle collecting portion formed below the inner cylinder portion,
Connected to at least a part of the side wall portion or to the lower end of the inner cylindrical portion, or connected to at least a part of the side wall portion and the lower end of the inner cylindrical portion, since a filter cloth portion having a filter cloth is provided,
The dust-containing gas enters the housing from the dust-containing gas introduction opening along the inner wall, for example, in a tangential direction, turns inside the housing, distributes coarse dust particles to the outside, and distributes fine dust particles to the inside. Move upwards. During this time, the air flow in the dust-containing gas flow flows out of, for example, the filter cloth portion on the side wall, and the dust-containing gas introduced into the housing has a reduced flow velocity in the housing, and the dust particles are concentrated. With increasing chance of contact with each other, they are separated from the gas stream and collected in the dust particle trap.

When the gas introduced from the dust-containing gas introduction opening moves to the side where the diameter of the housing increases,
Along with the movement, the flow path is expanded in the radial direction, the turning diameter increases from the inside to the outside, and a part of the air flow from the filter cloth part formed on at least one of the inner cylinder part and the side wall part of the housing. Flows out, the flow velocity is reduced, and coarse particles distributed in the outer peripheral part and particles having a relatively large particle diameter distributed in the intermediate part settle, and the dust is collected in the dust collecting part on the bottom wall of the housing. And the process of separating particles can be shortened. Further, according to the present invention, since the inner flow has a smaller flow velocity than the outer flow, the flow containing fine particles gathers inside and flows into the inner cylinder from the lower end of the filter cloth portion of the inner cylinder. When flowing into the inner cylinder part, a part of fine particles loses inertia by colliding with a rectifying plate part provided at an inlet part of the filter cloth part, settles on a baffle plate part, and a housing bottom wall part It is collected and collected. In the present invention, a dust-containing gas flow containing relatively fine particles separated from relatively large particles is blocked by the baffle plate and changes its direction to enter the lower opening of the inner cylinder. However, the flow is interrupted by the flow regulating plate portion, and the fine particles having a small particle diameter lose inertia and settle.

When the dust collecting apparatus of the present invention is formed to be foldable, the ceiling, bottom wall, side wall, inner cylinder, baffle plate and rectifying plate are made of a flexible material, For example, it can be made of a sheet or film of a soft and lightweight material made of canvas, filter cloth, or plastic material, or a cloth material. When the dust collecting device is formed so as to be foldable in this way, the dust collecting device has a ceiling portion, a bottom wall portion,
The side wall portion, the inner cylinder portion, and the current plate member can be sewn together or connected by fasteners such as slide fasteners to form a cyclone type dust collector. Also, when attaching the inner cylinder portion to the housing, the inner cylinder portion can be sewn to the housing, or connection means such as a fastener such as a slide fastener can be applied, and the cyclone type dust collector can be made relatively lightweight and relatively simple. Can be manufactured.

In the dust particle collecting portion of the housing, an openable / closable dust particle taking-out port for taking out the dust particles collected by the dust particle collecting portion can be formed. The dust collection particle outlet is preferably formed to be openable and closable by an openable fastener such as a slide fastener. Further, the dust collector of the present invention can be stored without requiring a large storage space because it is not bulky when folded when not in use, and is convenient for transportation, so that it can be transported for other uses. In place, the folded housing can be opened and assembled for use. As described above, the dust collecting apparatus of the present invention is convenient for transportation.By transporting, the single dust collecting apparatus can be used for dust collection processing of the exhaust of many grain processing apparatuses, and can also be used for a plurality of grain processing apparatuses. And the cost of the exhaust dust collection process can be reduced.

In the embodiment shown in FIG. 1, a cyclone type dust collector 1 for dust collection processing of dust-containing gas exhaust has a circular cross section, and a ceiling member forming a ceiling portion 2 A flat tubular guide tube 3 is attached to the periphery of the ceiling 2 by sewing, and a hole 4 of the guide tube 3 is used in use.
Through the steel wire (not shown), the ceiling 2 can be formed in a circular shape by the elasticity of the steel wire. Further, a filter cloth portion 5 formed in a hollow cylindrical shape is formed at the peripheral edge of the ceiling 2 by sewing the upper end thereof to the peripheral edge. In this example, the filter cloth member forming the hollow cylindrical filter cloth portion 5 is formed of a nylon woven filter cloth for filtering water. In this example, in order to keep the cross-sectional shape of the filter cloth portion 5 substantially circular, a disk-shaped bottom wall portion 6 is formed by sewing at the peripheral edge of the lower end portion of the filter cloth portion 5. A thin tubular guide tube member 7 is formed by sewing on the peripheral portion of the wall portion 6. In use, the steel wire 26 (see FIG. 5) is passed through the steel wire 26 (see FIG. 5) in the hole 8 of the guide tube portion 7. The peripheral edge of the bottom wall 6 is pulled outward by the elasticity of the wire, and the bottom wall 6
Can be formed to have a substantially circular planar shape.

In this embodiment, the housing 9 is formed by the ceiling part 2, the filter cloth part 5, and the bottom wall part 6. In this example, the dust-containing gas introduction pipe 10
Are connected, and the dust-containing gas introducing pipe 10 is opened in the housing 9 in a tangential direction. In this example,
A clean gas outflow opening 11 is formed in the ceiling 2, and a hollow cylindrical inner cylindrical portion 12 made of canvas is attached to the periphery of the clean gas outflow opening 11 by sewing the upper end thereof. Have been. In this example, a suspending string 14 is attached to the peripheral portion 13 of the ceiling 2 of the dust collecting apparatus 1, and the suspending section 14 is attached to the suspending string 14 in use during use. (Not shown), the dust collecting device 1 can be suspended.

In this example, the lower end of the inner cylinder 12
A rectifying plate portion 15 formed by a clogged cloth partition plate member is provided by sewing, and a baffle plate portion 16 formed by a baffle plate member is provided. The baffle plate portion 16 is formed in a disk shape, and a thin tubular guide tube portion 17 for guiding a steel wire is attached to an edge of the baffle plate portion 16 by sewing, and is used at the time of use. , Guide tube 1
7, a steel wire 261 (see FIG. 5) is passed through the steel wire 261 to form the baffle plate member of the baffle plate portion 16 in a circular shape. Can be formed. In the present example, the gap 19 between the lower end of the inner cylindrical portion 12 and the baffle plate portion 16 is an inflow port of the dust-containing gas into the inner cylindrical portion 12, and the dust-containing gas flows through the gap 19. At the stage of flowing into the inner cylindrical portion 12, it collides with the partition plate portion 15 and the baffle plate portion 16, loses inertia, is collected by inertia, and rises inside the inner cylindrical portion 12 in a rectified state, Further dust is collected. In the present embodiment, the bottom of the housing 9 below the baffle plate 16 serves as a dust particle collection unit 20.

Since this embodiment is configured as described above,
The cyclone-type dust collector 1 which is folded and accommodated is taken out, the folded housing 9 is unfolded and opened, and the inside of the holes 4 and 8 of the guide tubes 3 and 7 of the ceiling 2 and the bottom wall 6 are taken. Through the steel wire 26 (see FIG. 5) and the ceiling 2
And the bottom wall 6 is formed in a state of being stretched in a circular shape.

Shape. In this example, when the housing 9 of the dust collecting device 1 is used for processing a dust-containing gas having a relatively high dust concentration, the volume per unit air volume is increased and the height is increased. In the case of treating a dust-containing gas having a relatively low gas content, the volume per air volume can be reduced and the height can be reduced. For example, exhaust gas from a cereal processing facility containing a relatively large amount of dust but a small amount of exhaust air is introduced into the housing 9 from the dust-containing gas introduction pipe 10.

The dust-containing gas introduced tangentially into the housing 9 from the dust-containing gas introduction opening 10 turns along the inner wall surface of the housing 9 and moves upward with relatively large dust particles distributed outside. I do. Part of the clean gas from the swirling flow is filtered out of the filter cloth portion of the filter cloth side wall portion 5 and flows out. Therefore, the swirling speed gradually decreases as it moves upward, and relatively large particles are separated.
