[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic transportation server for pneumatically transporting a granular material. More specifically, the present invention relates to a method for mixing a granular material and a high-pressure gas in a granular material pneumatic transportation server and discharging the mixture to a pneumatic transportation pipe.

[0002]

2. Description of the Related Art Various inventions have been made with respect to servers for transporting pulverized particles or the like. For example, see JP-A-11-13

872, JP-A-6-56267, JP-A-6-405
As shown in No. 61 and the like, there is a pressure supply source for supplying a pressurized gas, a hopper for supplying a granular material, and a device in which the compressed gas and the granular material are joined by a transport pipe downstream of the hopper. Various equipment such as instruments and valves are arranged from the pressure supply source to the transport pipe. Further, for example, a mixing machine for pneumatic transportation of grains and the like therein (Japanese Patent Application Laid-Open No. 63-66021).
However, this is provided between the air intake pipe and the discharge pipe, by providing a swelling chamber in which the front pipe and the rear pipe are screwed to each other to make the length adjustable, and the front pipe of the front pipe is provided. An inclined wall is formed on the inner wall, and a gently bent introduction pipe extending from the hopper is inserted into the retention chamber, and its tip is formed in a narrow injection hole by approaching the inclined wall. A part of the bent portion is opened toward the air intake pipe, and a branch pipe for introducing the air flow is communicated with the pipe, so that the diameters of the air intake pipe, the discharge pipe, and the introduction pipe are substantially equal, and the front pipe is connected to the front pipe. The vertical cross-sectional area of the space sandwiched between the inner wall and the inlet pipe is substantially equal to the vertical cross-sectional area of the air intake pipe. Thereby, the flow of the transport is smoothed, the injection pressure can be adjusted, and a mixing machine having a minimum pressure loss is exemplified.

[0003]

However, the conventional general idea is that the hopper and the pressurized air supply device are separated from each other, and there is a problem that maintenance is troublesome and the equipment becomes large. That is, a pressure air supply device such as a valve, a pipe, and an instrument is complicated, and various inconveniences are caused. In addition, as disclosed in Japanese Patent Application Laid-Open No. 63-66021, a mixer is provided below an outer region of a hopper, but none of the conventional ideas has been proposed. That is, in what is described in the prior art, in order to perform a mixture formation process outside the hopper, at the place where air and powder intersect,
Turbulence is likely to occur in the high-pressure gas, energy loss occurs, transport efficiency is reduced, and the equipment is complicated and large. Further, although suitable for low-concentration high-speed pneumatic transportation, high-concentration low-speed pneumatic transportation is difficult and has a drawback that the applicable range is limited. Further, in the conventional mixing machine, the powder may adhere to and grow on the inner wall and corners of the hopper, which may cause various problems such as hygiene.

[0004] The present invention has been made in view of such various problems of the prior art, and an object of the present invention is to provide one that can solve the above-mentioned problems. Furthermore, in order to realize a double-pipe air transport pipe, pipes must be connected to the inner pipe and the outer pipe from high-pressure gas tanks, respectively, and the receiver tank,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A pneumatic transportation server 1 according to a first embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. As shown in FIG. 1 and FIG. 2, the server 1 for transporting a granular material of the first embodiment smoothly mixes a mixture of a granular material and a high-pressure gas (for example, high-pressure air for transportation) in a double manner. A high-pressure gas supply unit 3 comprising a pipe or the like, and a high-pressure gas chamber 4 communicating with the high-pressure gas supply unit 3 is provided with a double-pipe structure for feeding into the pneumatic transport pipe 2 having a pipe structure. A hopper 6 communicating with the high-pressure gas chamber 4 through a passage 5 (here, a hole) provided in an upper portion;
A gas mixture forming chamber 7 which forms a gas mixture of the granular material and the high-pressure gas, an internal pipe 9 connected to an outlet 8 provided at a lower portion of the gas mixture chamber 7, A base 13 provided with an outlet portion 10 having a double pipe structure provided at an end portion.
It has. Granules are supplied from above to the gas mixture forming chamber 7, high-pressure gas is supplied from the high-pressure gas chamber 4 to the gas mixture forming chamber 7, and the granules supplied to the gas-mixing chamber 7 are subjected to internal piping by gravity. The high-pressure gas that has dropped toward 9 and supplied to the mixture forming chamber 7 is supplied toward the internal pipe 9. As shown in FIG. 3, the outlet portion 10 has an inner pipe ventilation hole 11 having a relatively large diameter at the center in a side view and a predetermined number (single or plural, here, eight pieces) provided around the inner pipe ventilation hole 11. ) And an outer tube vent hole 12). In the hopper 6,
Since the high-pressure gas flows obliquely downward along the inclined inner wall and is collected at the center, the high-pressure gas is characterized in that powder adhesion to the inner wall of the hopper 6 is suppressed. The above-described base 13 also serves as a high-pressure gas receiver tank.
Direct supply of high-pressure gas in pneumatic transportation becomes possible, eliminating the need for receiver tanks and pipes installed to secure stable pressure and air volume, saving space and
It leads to cost reduction. In particular, the high pressure gas supply unit 3
Since it can be a location, the structure can be simplified. As shown in FIG. 1, the internal pipe 9 is composed of a bend pipe, a reduced-diameter pipe, and a horizontal straight pipe, and diverts the flow substantially from below to the side. In addition, a high-pressure source (compressor, blower, etc.) for supplying a high-pressure gas to the high-pressure gas supply unit 3 is separately installed in a place (not shown).

A powder supply opening 15 having a predetermined shape (round, square, etc.) is formed in the upper surface plate 14 of the base 13, and a predetermined shape (round shape) for connecting a base portion 17 of a rotary valve 16 around the opening 15. , Square, etc.). As shown in FIG. 1, a powder-particle supply cylinder 19 formed in a rectangular cylindrical shape extends downward from the connection plate 18 into the mixture forming chamber 7. The powder supply tube 19 is for substantially obliquely lowering the flow of the high-pressure gas flowing laterally from the annular space on the outer periphery thereof, and is capable of preventing the turbulence by smoothing the flow of the high-pressure gas. You can do it. A motor 28 is directly connected to the rotary valve 16. The rotary valve 16 may be indirectly connected to the motor 28 via a driving mechanism. A powder-particle receiving container 20 (a hopper in the present embodiment) having a predetermined shape (square, round, or the like, and square here) is connected to an upper opening of the rotary valve 16. In short, the server 1 is divided into an upper part and a lower part by the upper surface plate 14. The high-pressure gas is received from the high-pressure gas supply unit 3, the high-pressure gas is discharged from the passage 5 or the outer pipe vent 12, and the rotary valve 16 and the air-fuel mixture forming chamber 7 are communicated with each other to receive the powder from the upper part. . Others are kept airtight.

The rotary valve 16 has a well-known structure provided with rotary blades 16a (also referred to as rotors) rotatably supported for transporting powder and granular material, and includes a rectangular casing member 16b, a bearing 16c, and a main body. It is composed of a powder transporting chamber 16d surrounded by a casing 16b, and entrances provided above and below. Here, only the illustration is given, and details are omitted, but here, a so-called air lock function is provided.

Powder container 20 and rotary valve 1
6. The granular material is supplied to the air-fuel mixture forming chamber 7 through the granular material supply cylinder 19, while the high-pressure gas is supplied from the passage 5 above the hopper 6, and the granular material is passed through the granular material supply cylinder 19. Falls by gravity. A part of the powder is forcedly dropped along the inclined inner wall of the hopper 6, and the central part is free-falled.
It falls while being contracted toward the lower part. The high-pressure gas supplied into the mixture forming chamber 7 is supplied downward toward the lower part of the hopper 6, and the mixture is formed in the mixture forming chamber 7. Blower,
The high-pressure gas chamber 4 becomes positive pressure by a compressor or the like, and the high-pressure gas is supplied to the inside of the air-fuel mixture forming chamber 7. In the case of the suction type instead of the pressure feed type, the high-pressure gas supply unit 3 serves as an inlet for the high-pressure gas, and the high-pressure gas chamber 4 has a negative pressure.

From the rotary valve 16 to the hopper 6
The powder and granules are discharged into the air-fuel mixture forming chamber 7 inside,
The supply of the high-pressure gas from the high-pressure gas chamber 4 to the air-fuel mixture forming chamber 7 allows the granular-material-pneumatic-transport server 1 to serve as a source of the pneumatic-particle transport.

The shape, the number (single or plural) of the high-pressure gas supply unit 3 or the passage 5 and the location can be set as appropriate. The outlet of the rotary valve 16 may be square or round.

The rotary valve 16 and the granular material receiving container 20 (excluding the upper opening) are covered with a cover 21.
An instrument 23 for transporting powder and granular material such as a thermo-hygrometer and a pressure gauge is used as an upper plate 1 of a base 13 serving as a receiver / tank base.
4 and covered with the cover 21, it is possible to very easily perform quality control, adjustment of products by heating and humidification, and adjustment of pneumatic transportation conditions. The main object to be measured by the instrument 23 for transporting the granular material is the high-pressure gas chamber 4.
High pressure gas inside. Further, the control panel 24 is attached to the cover 21.
Is installed. Note that a drain 25 is arranged below the base 13.

Instead of the rotary valve 16, the screw feeder 30 shown in FIG. 4, the multiple damper 40 (for example, a double damper) shown in FIG. 5, or another equivalent can be used. The screw feeder 30 shown in FIG. 4 is for continuously supplying powders and granules, and is suitable for low-concentration high-speed pneumatic transportation and the like.
In addition to a rotary valve having an air lock function for pneumatic transportation, there is a multiple damper 40 shown in FIG. The multiple damper 40 includes a plurality of first hoppers 41, a second hopper 42,
A hopper 43 is provided, and a first flap portion 44 and a third hopper 43 are provided between a lower portion of the second hopper 42 and an upper portion of the third hopper 43.
Is provided with a second flap portion 45 at the lower portion of the first flap. First
In this structure, the flap portion 44 and the second flap portion 45 are opened and closed alternately at regular intervals. Air pressure shutoff (airlock) is possible to some extent. Rotary valve 1
6. The screw feeder 30 and the multiple damper 40 have a continuous transport structure. Certainly, when the pocket (trough) of the rotary valve 16 rotates and the powder falls from the pocket, a certain amount of the powder is repeatedly stored and dropped, so that the supply is substantially pulsating and intermittent. But it is not batch processing. Strictly speaking, it is pulsatile but generally continuous.

The server 1 for transporting powdered air power is widely applicable to high-concentration powdered gas transport, medium-concentrated powdered gas transport, low-concentrated powdered gas transport, and the like. Which is determined by the mixing ratio of the gas and the granular material used during pneumatic transportation changes depending on the air volume, the pipe diameter, the supply amount of the granular material of the rotary valve, and the like.

The operation of the server 1 for transporting powder and granular energy will be described. High-pressure gas (not shown) is supplied from a high-pressure source (compressor, blower, etc.) to the high-pressure gas chamber 4 via the high-pressure gas supply unit 3, a part of which is supplied to the mixture forming chamber 7 via the passage 5, and the other is supplied. The air is supplied to the outer passage of the pneumatic transport pipe 53 through the outer pipe vent 12 of the inner pipe 9. The high-pressure gas supplied to the outer passage mainly passes through the inner pipe 5 of the pneumatic transport pipe 53.
It compensates for the decrease in gas pressure within 1. on the other hand,
The granular material is supplied to the inlet of the rotary valve 16 through the granular material receiving container 20, transferred downward while being rotated by the rotor, and falls from the outlet of the rotary valve 16 to the mixture forming chamber 7. The high-pressure gas is supplied from the passage 5 to the air-fuel mixture forming chamber 7, and the air-fuel mixture is formed in the air-fuel mixture forming chamber 7. The air-fuel mixture passes through the internal pipe 9 from the inner pipe (inner passage) of the outlet 10. It is transported to the inner passage of the pneumatic transport pipe 2 having a double pipe structure. In short, along with the direction of gravity, the granular material and the transport air fall, and are smoothly supplied to the internal pipe 9,
This eliminates the possibility of generating a turbulent flow inside the hopper 6, thereby preventing energy loss and realizing smooth transportation. Also, for example, granules (eg, rice grains, coffee beans, etc.)
When pneumatic transportation is performed, particles can flow down smoothly along the inclined surface of the hopper 6, and the possibility that the particles collide with the wall surface and be broken can be eliminated.

(Example of Application to Highly Concentrated Air Transport) An example in which the granular material pneumatic transport server 1 is applied to a powdery high concentration air transport piping system 50 will be described with reference to FIG. A pneumatic transport pipe 53 having a double pipe structure including an inner pipe 51 and an outer pipe 52 is connected to the outlet portion 10 having the above-described double pipe structure. The high-pressure gas is supplied from the high-pressure gas supply unit 3 to the high-pressure gas chamber 4, and the high-pressure gas is supplied from the high-pressure gas chamber 4 to the mixture forming chamber 7 via the passage 5. On the other hand, the granular material is supplied from the rotary valve 16 through the granular material supply cylinder 19 to the mixture forming chamber 7, and the mixture formed in the mixture forming chamber 7 is supplied to the internal pipe 9 and the inner pipe vent 11. Through which the plug-shaped mixture is transported to the inner passage 60 of the pneumatic transport pipe 53. On the other hand, a part of the high-pressure gas in the high-pressure gas chamber 4 is supplied to the outer passage 61 of the pneumatic transport pipe 53 through the outer pipe ventilation hole 12.

Hereinafter, details of the pulverized material high concentration pneumatic transportation piping system 50 will be described. As shown in FIG.
Is provided with a straight pipe portion 54, a cross-sectional area changing portion 55 (a constricted portion or a bulged portion), and a bend portion 56. In addition, the pulverized material high-concentration air transport piping system 50 is a double-pipe structure piping system including a rotatable horizontal piping plug forming device 57 and an auxiliary air supply device 58. It transports plugs and a layer of pressurized air. That is, the pneumatic transport pipe 53 has a double pipe structure as described above, and is composed of the inner pipe 51 and the outer pipe 52, and the inner passage 60.
The plug and the pressurized air layer are alternately transported, and the outer passage 61
Are filled with auxiliary high pressure air. The pressure in the outer passage 61 is set higher than the pressure in the inner passage 60. In the embodiment, the material of each part of the high-concentration pneumatic transportation piping system 50 is a metal, for example, SUS and duralumin, but other appropriate materials can be adopted. Also, the shape may be an appropriate shape such as a square cross section and a round cross section.

As shown in FIG. 7, the auxiliary air supply device 58 is provided with a manual valve 81 capable of adjusting an appropriate flow rate by turning a screw, and the auxiliary high-pressure air filling the outer passage 61 by the operation of the valve 81 is tapered as shown by an arrow. It flows into the inner passage 60 through the hole 88 having a shape of a circle. This is because the air pressure in the outer passage 61 is set to be higher than the air pressure in the inner passage 60. The opening and closing of the hole 88 and the adjustment of the amount of air can be performed by the vertical movement of the manual valve 81. The auxiliary air (high-pressure air) is supplied to the high-pressure gas chamber 7, the internal pipe 9, the outer pipe vent 1
After that, it is supplied to the outer passage 61. In addition, the auxiliary air can be provided by a temperature control device and a humidity control device (not shown) that can be installed inside the server 1. In particular, if the auxiliary air is installed above the upper plate 14 like a meter, space can be saved. It is adjusted appropriately. Temperature control device,
The humidifier can also regulate the transport air passing through the inner passage. In any case, in the case of cooling,
Supply air via chiller. To prevent moisture absorption, dry air is supplied via a dryer. In the case of dehumidification, it becomes dry, and air is heated and supplied via a heater.

As an example of the pipe connection structure, although not shown, a ferrule is formed at the end of the pipe by welding or the like, and a ferrule is brought into contact with the pipe and fastened with a clamp so as to be detachable. Thereby, the clamp is detached and disassembled, and the inside can be inspected. The connection structure is formed at both ends of the straight pipe portion 54, the sectional area changing portion 55, the bulging portion, and the bend portion 56,
Airtightness is ensured.

In the piping system 50 of the present embodiment, it is significant that the piping has a double pipe structure as described above. The above-mentioned valve 8 is transferred from the outer passage 61 of the double pipe structure to the inner passage 60.
Auxiliary high-pressure air is passed through 1 and the like to assist in reducing the internal pressure of the inner tube. If too much pressure is applied to the inside of the pipe, although the accuracy of the rotary valve of the server 1 for transporting granular power may increase, air may leak, so that high pressure may not be applied to the inside of the pipe. is there. Then, the transport pressure in the pipe decreases on the way.
Therefore, it is necessary to supplementally supply high-pressure air to the pipe at appropriate intervals or at predetermined intervals. Further, the high-pressure air flowing through the inner tube has a property that it is too dry to some extent without any operation, and the moisture of the powder and granules is absorbed, so that it is necessary to humidify the air. For example, rice is easily broken when it is too dry. Therefore, when transporting such a granular material, it is necessary to humidify to some extent, and a humidifier is provided at an appropriate place, and the transported material is supplied by supplying humidified auxiliary air to the gap of the double pipe structure. For example, damage of grains (rice, etc.) is prevented.

As shown in FIG. 8, the pneumatic transportation server 1 of the first embodiment may be connected to a pneumatic transportation pipe 90 having a simple double pipe structure. In this case, it is preferable to apply the method mainly to high-speed pneumatic transportation of low-concentration powder and pneumatic transportation of low-concentration powder. In the case of low concentration high speed pneumatic transportation,
As shown, a receiver filter 91 with a fan is provided at the downstream end.
And a rotary valve 92, and a roots blower 93 is connected to the receiver filter 91 via a rotary valve 94 for pressure-feed lock.

Next, a description will be given of a server 201 for power transmission of a granular material according to a second embodiment with reference to FIGS. 9 and 10. FIG. Since the powder / particles power transfer server 201 supplies high-pressure gas to the single-structure power transfer pipe system 250 shown in FIG. 11, the outlet 10 of the double-pipe structure of the first embodiment is used.
Is replaced with the outlet part 210 having a single structure, and the outer pipe vent 1
2 has been deleted. Otherwise, the structure is the same as that of the first embodiment. The part numbers are only shown in the 200s, and the description is incorporated.

(Explanation of Comparative Example) FIG. 12 shows a pneumatic power transport server 301 of a comparative example. In order to supply high-pressure gas to the pneumatic transport pipe 53 having a double pipe structure in the same manner as the above-described pneumatic transport server 1, a structure as shown in FIG. It is more disadvantageous than the physical energy transport server 1. That is, the server 301 for power transmission of the granular material of the comparative example includes the base 313.
, A hopper 306 fixed to a base 313, and a rotary valve 3 connected to an upper portion of the hopper 306.
16, a hopper 320 connected to the upper part of the rotary valve, an internal pipe 309 connected to the hopper 320, an outlet 310 connected to an end of the internal pipe 309 and having a double pipe structure, and the like. A compressor 330 as a high-pressure gas source and a receiver tank 340 for stabilizing the pressure of the high-pressure gas are installed. The compressor 330 and the receiver tank 340 are connected by a pipe 332, and the receiver tank 340 and the hopper 306 are connected by a pipe. The connection is made at 334, and the receiver tank 340 and the outside passage of the outlet 310 are connected by a pipe 336 branched from the pipe 334. The high pressure gas from the compressor 330 passes through the receiver tank 340 and the pipe 334,
06, and a mixture is formed by the hopper 306. Meanwhile, the receiver tank 340 and the pipe 336
Through the outlet section 310. As described above, since it is necessary to separately install the receiver tank 340 and supply air to two locations, two piping systems are also required. On the other hand, the granular material viscous transport server 1
The receiver tank 340 and the pipes 334 and 336 can be omitted, a stable high-pressure gas can be supplied, and downsizing and low cost can be realized.

(Effects of Embodiment) According to the server 1 for transporting pneumatic power of the present embodiment described above, the following effects are obtained. (1) Since both the flow direction of the powder and the high-pressure gas are substantially the same (downward), turbulence does not occur in the hopper 6, and the powder is more easily fluidized. The flow is smooth. (2) Since the high-pressure gas supplied into the hopper 6 smoothly mixes with the granular material, for example, when the granular material is granular,
There is little or no crushing on the wall of the hopper 6 riding on the momentum of the gas. (3) Since the base 13 incorporates the high-pressure gas chamber 4, it is not necessary to separately provide a receiver tank and the piping system can be simplified. When the pneumatic transport pipe is a double pipe, the outer passage of the pneumatic transport pipe communicates with the high-pressure gas chamber 4, the high-pressure gas chamber 4 communicates with the hopper 6 through the passage 5, and the internal pipe 9 is connected to the hopper 6. By connecting the inner passage of the pneumatic transport pipe through the intermediary, a server of the pneumatic transport system for the double pipe can be constructed. (4) The present embodiment can be applied to other uses, such as low-concentration pneumatic transport, in addition to high-concentration pneumatic transport.
Wide application range.

It should be noted that the present invention is not limited to the above-described embodiment, but may be modified without departing from the technical idea of the present invention.
Such modifications and equivalents are also included in the technical scope of the present invention. For example, a server 1 for transporting granular power
The present invention is not limited to the above-described example, and the shape, arrangement, structure, and the like can employ an appropriate configuration without departing from the spirit of the invention, and it is a matter of course that equivalents are included.
