Description
Technical Field
The present invention relates to a vibration drying device that dries a material while conveying the material by vibration.
Background
As a conventional vibration drying device, there is a vibration drying device described in patent document 1. This vibration drying device includes: a flow regulating plate for conveying a material in a powder form, for example; and a gas supply member for supplying gas into the gas supply chamber formed in a box shape below the rectifying plate and passing the gas through a plurality of opening holes provided in the rectifying plate, wherein the vibration drying device is configured to supply gas to a material being conveyed and dry the material, and has a partition plate for changing a flow of the gas supplied in a width direction of the gas supply chamber.
According to the description of patent document 1, with the above configuration, since the flow of the partial gas is changed by the partition plate, the flow rate of the gas blown up by colliding with the wall surface of the gas supply chamber is reduced, and the flow velocity of the gas passing through the opening hole of the rectifying plate near the wall surface is not increased. Therefore, the material near the wall surface is not pushed by the gas, the deviation of the material in the width direction of the gas supply chamber is reduced, and the material can be fluidized and dried uniformly.

Problems to be solved by the invention
However, since the flow of gas passing through the opening holes of the rectifying plate is changed depending on the size of each material and the density of the material, adjustment of changing the installation angle of the partition plate in the gas supply chamber may be necessary. Further, since the vibration drying device conveys the material in a particle shape, for example, the material is ground during conveyance, and the chips and powder generated by grinding fall into the air supply chamber. Therefore, cleaning of the inside of the apparatus is sometimes required.
However, in the vibration drying device described in patent document 1, since the partition plate is provided inside the air supply chamber, the partition plate cannot be accessed without detaching the rectifying plate or the cover of the vibration drying device itself at the time of maintenance such as adjustment or cleaning. However, there is a problem that a large-sized vibration drying device having a length in the longitudinal direction of several meters to several tens of meters is also used in the vibration drying device, and therefore a burden during maintenance is large. In order to cope with this problem, it is necessary to maintain the basic function of the vibration drying device, that is, to uniformly supply air to the flow straightener.
Therefore, an object of the present invention is to provide a vibration drying device with good maintainability, which maintains uniform supply of air to a rectifying plate and does not require disassembly of the rectifying plate during maintenance.
Means for solving the problems
The present invention is a vibration drying device, comprising: a flow regulating plate which is permeable in the thickness direction and which conveys a material placed thereon by vibration; an air supply chamber located below the rectifying plate; and a gas supply section for supplying gas to the gas supply chamber, the gas supply section including: a gas inlet portion penetrating a wall defining the gas supply chamber; and a tubular flow guide portion which is attachable to and detachable from the gas inlet portion, the flow guide portion being inserted from an outer side to an inner side of the gas supply chamber, the flow guide portion including: a side surface portion extending along an inner circumference of the gas inlet portion; and an end surface portion located at an inner end in the axial direction, the plurality of ventilation holes penetrating the side surface portion and the end surface portion.
With this configuration, gas is introduced into the gas supply chamber through the gas holes in the side surface portion of the deflector portion, and gas is introduced into the gas supply chamber through the gas holes in the end surface portion, whereby gas flows having different directions can be generated inside the gas supply chamber. This makes it possible to generate an air flow in the air supply chamber under conditions optimal for the material to be transported over the flow regulating plate. Also, the guide part can be easily detached from the gas inlet part.
Further, in the present invention, the gas inlet portion is located at a side wall defining the gas supply chamber, the plurality of vent holes are formed along a circumferential direction at the side surface portion of the flow guide portion, and a non-vent portion having no vent hole formed therein is provided at an upper portion of the side surface portion and in a region extending in the circumferential direction from each of the plurality of vent holes.
With this configuration, since the gas can be introduced into the gas supply chamber without passing through the upper portion of the side surface portion, the flow directly from the flow guide portion toward the flow regulating plate can be reduced, and the flow velocity distribution of the gas flowing through the flow regulating plate can be adjusted.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the present invention, an air flow having conditions optimal for a material to be transported over the flow regulating plate can be generated in the air supply chamber. Also, the guide part can be easily detached from the gas inlet part. Thus, it is possible to provide a vibration drying device with good maintainability that maintains uniform supply of air to the flow rectification plate and does not require disassembly of the flow rectification plate at the time of maintenance.

Detailed Description
The present invention will be described below with reference to the accompanying drawings by way of examples. In the following description, the expression of the direction is defined as the following relationship, except for the case where the reference of the direction is described in particular. The up-down direction is in accordance with the up-down direction shown in fig. 2 and 5. The inner and outer directions are based on the inner and outer directions with respect to the air supply chamber 4. Further, the width direction depends on the width direction of the apparatus main body 2.
First, the entire configuration of the vibration drying device 1 of the present embodiment will be described. However, since the basic configuration is the same as the conventional one, the description will be briefly made. As shown in fig. 1 (a) and 1 (B), in the vibration drying device 1 of the present embodiment, a box-shaped device body 2 is supported from below by a spring support member 51 so as to be swingable. The left-right direction in fig. 1 (a) is the longitudinal direction of the vibration drying device 1, and the up-down direction is the width direction of the vibration drying device 1.
The apparatus main body 2 is defined by a side wall 211 defining the periphery, a bottom wall 212 defining the lower part, and a top wall 213 defining the upper part, and a space is formed inside. A rectifying plate 3 is disposed in the horizontal direction inside the apparatus main body 2. The apparatus main body 2 is vibrated by the vibration member 5. A material inlet 22 is formed at the left end of the top wall 213 of the apparatus main body 2, and a material outlet 23 is formed at the right end of the bottom wall 212 of the apparatus main body 2. The material M (schematically shown in fig. 1 (B) and 5) charged into the apparatus main body 2 is conveyed on the rectifying plate 3 in the direction of the arrow D shown in fig. 1 (B). The material M to be conveyed and dried by the vibration drying device 1 of the present embodiment is, for example, a material that is amorphous in a state of being aggregated, such as a powder shape, and is used in various fields such as food, medicine, fertilizer, and industrial material.
Fig. 2 and 3 relate to the apparatus main body 2, and for the sake of explanation, each of the plurality of structural units 2U of the gas inlet portion 61 … 61 of the gas supply member 6 is shown as being separated (not necessarily limited to the physical separation of the apparatus main body 2 into the plurality of structural units 2U … 2U). The apparatus main body 2 is formed by connecting a plurality of constituent units 2U … 2U in the longitudinal direction (the direction extending from the upper left to the lower right in fig. 2 and 3). Hereinafter, one structural unit 2U will be described.
The structural unit 2U includes a rectifying plate 3, an air supply chamber 4, and an air supply member 6 (respective parts).
The rectifying plate 3 is permeable in the thickness direction, and is a portion for conveying the material M placed thereon by the vibration generated by the structural unit 2U by the vibrating member 5. As the flow regulating plate 3, for example, punched metal is used, and the gas flow can pass through the small through holes 31 … 31 (only a part of which is shown in fig. 2 and 3) formed in plural. Preferably, each of the small through holes 31 is set to a size such that the air flow can pass but the material M being conveyed does not fall. Further, as shown in fig. 3, for example, the flow plate 3 is reinforced from below by a plurality of reinforcing portions 32 … 32 extending in the width direction.
Air supply chamber 4 is a portion located below rectifying plate 3, and air supply chamber 4 is defined inside and outside by wall portion 21 (specifically, side wall 211 and bottom wall 212) provided in the device main body. The gas supply unit 6 is a part for supplying gas to the gas supply chamber 4. The gas used in this embodiment is air.
The gas inlet portion 61 in the gas supply part 6 is illustrated in fig. 2 and 3. A blower 62 shown in fig. 1 (B) is connected to the gas inlet 61, and the gas is sent to the gas inlet 61 through an inlet flow path 63. Although not shown, the inlet channel 63 may be formed of two systems, for example, a heating channel having a heating member and a cooling channel having a cooling member. In this case, for example, the heating flow path may be connected to the gas inlet 61 located on the upstream side in the conveying direction, and the cooling flow path may be connected to the gas inlet 61 located on the downstream side in the conveying direction. Further, the gas flow sent to the gas inlet 61 passes through the rectifying plate 3 from below to above from the gas supply chamber 4, and is discharged from the gas outlet 24 provided in the ceiling wall 213 of the apparatus main body 2. The gas outlet portion 24 is connected to a dust collector 25 shown in fig. 1 (B), and collects powder and the like from the material contained in the exhaust gas.
The air supply member 6 of the present embodiment is a structure that does not exist conventionally, and includes: a gas inlet 61 penetrating through wall 21 of gas supply chamber 4; and a flow guide portion 64 that is detachably attached to the gas inlet portion 61, the flow guide portion 64 being inserted from the outside to the inside of the gas supply chamber 4. The gas inlet 61 of the present embodiment is a cylindrical portion, more specifically, a cylindrical portion, which penetrates the side wall 211 defining the gas supply chamber 4. However, the gas inlet 61 is not limited thereto, and the gas inlet 61 may have various shapes as long as the baffle portion 64 is attachable to and detachable from the gas inlet 61.
Fig. 4 shows a single shape of the flow guide portion 64. The flow guide portion 64 has: a side surface portion 641 extending along the cylindrical inner peripheral surface of the gas inlet portion 61; and an end surface portion 642 located at an inner end in the axial direction (an end portion close to the inside of the air supply chamber 4). The side surface portion 641 has a cylindrical shape, and the end surface portion 642 has a disk shape that closes an opening at the inner end of the side surface portion 641. A flange 643 is provided at an outer end in the axial direction of the flow guide portion 64. The flange 643 is positioned in the inward and outward direction of the flow guide portion 64 with respect to the gas inlet portion 61 by abutting against the outer end edge of the gas inlet portion 61. If the flow guide 64 has a circular cross-sectional shape perpendicular to the axial direction like the cylindrical side surface 641 of the present embodiment, the flow velocity distribution inside the flow guide 64 is simpler than that of the other cross-sectional shapes. Therefore, there is an advantage that the design for introducing a desired air flow into the air supply chamber 4 is easy.
A plurality of ventilation holes 644 … 644, 645 … 645 serving as holes for ejecting gas penetrate the side surface portion 641 and the end surface portion 642. A plurality of side vent holes 644 are formed along the circumferential direction. The side vent hole 644 of the present embodiment is a through hole having a rectangular shape when viewed in the radial direction, and the long side thereof is provided along the circumferential direction. However, the side vent hole 644 is not formed in a portion that is upward when attached to the gas inlet portion 61. That is, the guide portion 64 has a non-permeable portion 646 in which the side vent hole 644 is not formed in a region extending in the circumferential direction from each of the side vent holes 644 in the upper portion of the side surface portion 641 in the state of being attached to the gas inlet portion 61. The end surface portion side vent 645 is a circular through hole, and a plurality of holes are arranged along the circumferential direction. The end surface side vent holes 645 of the present embodiment are arranged on two concentric inner and outer lines (see fig. 6 a), and 6 end surface side vent holes 645 having the same size are formed on the inner circumferential side and the outer circumferential side, respectively.
By attaching the flow guide 64 configured as described above to the gas inlet 61, gas is introduced into the gas supply chamber 4 through the side surface portion side vent holes 644 of the side surface portion 641 of the flow guide 64, and gas is introduced into the gas supply chamber 4 through the end surface portion side vent holes 645. The air is radially blown out from the side vent hole 644 radially outward in a direction other than the direction in which the non-vent part 646 is formed. As a result, an air flow schematically shown by arrows in fig. 5 is generated inside the air supply chamber 4, and therefore, a flow rate in a region close to the gas inlet 61 can be secured. Further, since the baffle portion 64 includes the non-permeable portion 646, gas can be prevented from being introduced into the gas supply chamber 4 from the upper portion of the side surface portion 641. Therefore, the airflow directly from the flow guide portion 64 toward the flow rectification plate 3 (airflow at the shortest distance that does not detour with respect to the flow rectification plate 3) is reduced. Therefore, since a region in which the airflow passes intensively due to the shortest distance can be prevented from being generated in the flow rectification plate 3, the deviation of the flow velocity distribution of the airflow passing through the flow rectification plate 3 can be adjusted to be small. On the other hand, the air is blown out so as to diffuse radially outward from the end surface portion side vent holes 645 in the axial direction. This ensures a flow rate in a region away from the gas inlet 61 in the width direction inside the gas supply chamber 4.
By introducing the gas from the plurality of ventilation holes 644 … 644, 645 … 645 that are directed in different directions, gas flows in different directions can be generated inside gas supply chamber 4. This makes it possible to generate an air flow in the air supply chamber 4 under the conditions optimal for the material M conveyed over the flow regulating plate 3. Further, since the flow guide 64 of the present embodiment is configured to be attachable to and detachable from the gas inlet 61, the flow guide 64 can be easily detached from the gas inlet 61.
In contrast to the structure in which a partition plate as described in patent document 1 is provided in the air supply chamber 4 and is difficult to be taken out, in the present embodiment, the flow guide portion 64 is simply pulled out from the gas inlet 61 to the outside of the air supply chamber 4 at the time of adjustment or maintenance such as cleaning. Therefore, it is not necessary to detach the cover or the like to open the air supply chamber 4 and the apparatus main body 2. Therefore, the burden on the operator during maintenance is relatively small. Further, the function of uniformly supplying air to the flow adjusting plate 3, which is the basic function of the vibration drying device, can be sufficiently ensured.
Next, in the present embodiment, in each of the end surface portion side vent holes 645 of the plurality of end surface portion side vent holes 645 provided in the end surface portion 642 of the flow guide portion 64, the opening area of each of the end surface portion side vent holes 645 present at a position close to the center of the end surface portion 642 (center side) can be made the same as the opening area of each of the end surface portion side vent holes 645 present at a position away from the center of the end surface portion 642 (outer peripheral side) or, as shown in fig. 6 a, the opening area of each of the end surface portion side vent holes 645 present at a position close to the center of the end surface portion 642 (center side) can be made smaller than the opening area of each of the end surface portion side vent holes 645 present at a position away from the center of the end surface portion 642 (outer peripheral side). The "center" refers to the center of the airflow flowing through the tubular flow guide portion 64, and when the sectional shape is focused, the center is a position including a position having an equal distance from the edge of the sectional shape, for example, the center coincides with the axial center of the tubular shape. In the case of the configuration in which the opening area of the end surface portion side vent 645 on the center side among the end surface portion side vents 645 is smaller than the opening area of the end surface portion side vent 645 on the outer peripheral side, the flow velocity inside the flow guide portion 64 is large on the center side, and therefore the flow velocity can be adjusted by reducing the opening area.
In the present embodiment, the end surface portion side vent holes 645 provided in the disk-shaped end surface portion 642 are arranged along the circumferential direction and concentrically (arranged on a plurality of concentric lines). As shown in fig. 6 (a), the end surface portion 642 has a plurality of end surface portion side vent holes 645 located on the inner circumferential side and a plurality of end surface portion side vent holes 645 located on the outer circumferential side, which are offset in the circumferential direction. With this configuration, the airflow from the end surface side ventilation holes 645 located on the inner circumferential side and the airflow from the end surface side ventilation holes 645 located on the outer circumferential side can be made less likely to overlap in the circumferential direction. Therefore, the airflow is not likely to increase in speed, and therefore, the unevenness in the flow velocity distribution in the air supply chamber 4 can be reduced.
In the present embodiment, the plurality of side surface portion side ventilation holes 644 formed in the side surface portion 641 of the flow guide portion 64 are located in the vicinity of the inner surface of the side wall 211. The "vicinity" refers to a distance to the extent that the airflow from the side surface portion side ventilation holes 644 contacts the inner surface of the side wall 211. With this configuration, an airflow directed sideways from the flow guide portion 64 can be generated in the vicinity of the gas inlet portion 61 that opens into the gas supply chamber 4. Therefore, the gas flow can be generated over a wide range in gas supply chamber 4 from the end portion of gas supply chamber 4 near gas inlet portion 61.
The present invention has been described above by way of an embodiment, but the present invention is not limited to the embodiment, and various modifications can be made without departing from the scope of the present invention.
For example, in the embodiment, the gas inlet portion 61 is provided in the side wall 211. However, the present invention is not limited to this, and the gas inlet portion 61 may be formed in the bottom wall 212. In this case, the flow guide portion 64 is inserted from below to above.
The side surface 641 of the deflector 64 of the above embodiment is cylindrical, that is, has a circular (perfect circular) cross-sectional shape. However, the cross-sectional shape of the side surface part 641 is not limited to this, and may be polygonal, elliptical, or oval.
In the embodiment, the end surface portion 642 of the flow guide portion 64 has a disc shape. However, the present invention is not limited to this, and may be hemispherical or conical, for example. The end surface portion 642 of the above embodiment is arranged orthogonal to the axial direction. However, the present invention is not limited to this, and may be arranged so as to intersect the axial direction at an angle other than 90 degrees.
The flow guide portion 64 of the embodiment is provided with a single space inside. However, the present invention is not limited to this, and a member for guiding the airflow, such as a fixed blade (vane), may be provided inside the fan. Further, a mechanism for increasing or decreasing the energy of the airflow, such as a rotary blade (propeller), may be provided. Further, the partition wall may be provided to divide the space through which the airflow passes into a plurality of spaces. Further, a cylindrical body or a nozzle may be added to the end surface side ventilation holes 645.
The plurality of ventilation holes 644 … 644 and 645 … 645 of the diversion part 64 of the above embodiment are always open. However, the present invention is not limited to this, and the ventilation holes 644 and 645 may be configured to be openable and closable so that the aperture ratios thereof can be adjusted. For example, a movable cover can be attached to each vent 644, 645. For example, the guide portion 64 may be a combination of two cylindrical bodies in which one of the two cylindrical bodies enters the other cylindrical body. In this case, the configuration may be such that: the tubular bodies are provided with through holes, and the aperture ratio of the through holes can be adjusted by rotating the two tubular bodies relative to each other or by sliding them in the axial direction. By configuring in this manner, the aperture ratio of each of the ventilation holes 644 and 645 can be adjusted, and a desired airflow state can be easily realized inside air supply chamber 4.
