The powder is sent to the separator tank 30, which is scavenged by the blower 2.
The air is sucked into the interior from this suction nozzle 4A along with air. A cylindrical cyclone 31 is provided inside the separator tank 30 facing the outlet of the suction tube 4, and the powder discharged from the suction tube 4 is separated from the air by centrifugal force as it circulates around this cyclone 31. Only the air is sucked into the blower 2 from the intake pipe 3.

圧送される。This taper? B50A has a cross section that gradually narrows downward, and a rotary valve 32 that is rotationally driven by a motor 33 is interposed in the discharge port 9 at the tip. Further, a pressure-feeding chamber 12 connected to a pressure-feeding pipe 18 is formed below the rotary valve 32, and a blower pipe 10 of the blower 2 is connected to this pressure-feeding chamber 12. The powder deposited on the taber portion 30A is removed by the rotating rotary valve 3.

用される。This suction and pressure feeding device is used, for example, when supplying powder stored in a warehouse 25, a silo 26, or a bulk carrier 27 to a powder carrier 28 or a factory 29, as shown in FIGS. 5 to 7. .

あった。(Problems to be Solved by the Invention) By the way, in this device, air tends to flow into the separator tank 30 from the pressure-feeding chamber 12 as the rotary valve 32 rotates, and this inflow air is limited by the suction capacity of the separator tank 30. In addition, in the case of fine powder, the accumulated powder may be blown up by the inflowing air, making it difficult to separate the powder by the cyclone 31.

ャンバ１２がらセパレータタンク；）０への空気流入が
一ノ脅激しくなり、セパレータタンク３０の粉体及び分
離能力がますます低下してしまう。Further, since the powder is forced to be fed by the blower 2, the air supplied to the pressure feeding chamber 12 is at a relatively low pressure, and the air volume must be increased to ensure the necessary conveying capacity. In other words, a large amount of air containing low-concentration powder is forced to be fed, which inevitably increases the size of the pressure-feeding pipe 18 and the solid-gas separator (not shown) provided at its outlet. In order to avoid this, it is possible to supply high-pressure air to the pressure-feeding chamber 12 using a compressor or the like instead of blowing air from the blower 2, and to force-feed the powder at a high concentration. However, the inflow of air into the separator tank 30 becomes increasingly severe, and the ability of the separator tank 30 to separate powder and particles further deteriorates.
つまり、この装置においてはセパレータタンク３０への
流入空気のために粉体の高濃度圧送ができず、圧送対象
となる粉体も一定以上の粒径のものに限定されるという
問題があった。That is, in this device, there was a problem in that the powder could not be pumped at a high concentration due to the air flowing into the separator tank 30, and the powder to be pumped was also limited to particles of a certain size or more.

。(Means for Solving the Problems) The present invention sucks powder together with air through a suction pipe into a separator tank, separates the powder from the air with an internal separation device, and deposits the powder in the separator tank. At the same time, the accumulated powder is fed from the bottom of the separator tank to a tightly closed pressure-feeding chamber, and the powder is forced downstream through the pressure-feeding pipe by the pressurized air supplied to the pressure-feeding chamber. In the continuous suction and pressure feeding device, a cylindrical conveyance passage is formed between the discharge port of the separator tank and the pressure-feeding chamber, and a ti

Therefore, even when the valve device is in its full position, the powder accumulated behind the outlet blocks air flow through the conveying passage, and air does not enter the separator tank from the pressure-feeding chamber.

チャンバ１２へ落下する。The fallen powder is deposited on the bottom of the separator tank 1, and is gradually sent into the discharge passage 10 through the discharge port 9 which opens downward. Inside the carry-out passage 1o, a motor 24 is used to transfer the book to the first drawer, and a duster 15 forcibly transports the powder sent from the discharge port 9 forward, and a spring 13 It is compressed with the valve body 14 which is biased in the opposite direction. Note that the pitch of the screw blades 17 becomes narrower as it approaches the mower, and the outlet 10A of the conveyance passage 10 also has a tapered cross-section, so that the powder to be conveyed is more strongly compressed as it approaches the valve body 14. Also, since the valve bodies 14 interposed in the opposing outlets 10A are pressed by the same spring 13, which conveyance passage 10
The powder is also consolidated under the same pressure. On the other hand, the valve body 14, which receives conveying pressure from the rear through the consolidated powder, moves backward while bending the spring 13 as this pressure increases, and the powder pushed out in the 11th direction is forced to be fed from the front. It falls into chamber 12.

る。(Effects of the Invention) As described above, the present invention forms a conveyance passage between the outlet at the bottom of the separator tank and the pressure-feeding chamber, and provides a valve device at the outlet of the conveyance passage that opens in response to the powder pressure. At the same time, the conveyor passage was equipped with a screw feeder that conveyed the powder, so the powder compacted between the screw feeder and the valve device was deposited without any gaps at the outlet of the conveyance passage, and the valve device was opened. Even in this state, air circulation in the conveyance path is maintained in a blocked state. Therefore, air does not enter the separator tank from the pressure-feeding passage, improving the suction and separation efficiency of the separator tank, and also enables high-concentration powder to be pumped under high pressure, significantly increasing the pumping capacity.
