この発明は精米プラント等における米粒、米糠といった
粉粒体の空気輸送装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pneumatic transportation device for granular materials such as rice grains and rice bran in a rice milling plant or the like.
精米工場等の精米プラントにあっては、各機器間に配管
した輸送管に高圧空気を供給して米粒や米糠を搬送する
空気輸送装置（空気コンベヤともいう）が用いられる。In rice milling plants such as rice mills, pneumatic transport devices (also referred to as air conveyors) are used to transport rice grains and rice bran by supplying high-pressure air to transport pipes installed between each piece of equipment.
このものは、輸送物を投入した気密状のケーシング内に
高圧空気を供給し、ケーシングの送出口から高圧空気と
共に輸送物を輸送管内に栓状（パルス的）に送り出すこ
とによって輸送物を搬送するものくいわゆるプラグ輸送
）である。This system supplies high-pressure air into an airtight casing into which the cargo is placed, and then sends the cargo along with the high-pressure air into the transportation pipe in a plug-like manner (pulse-like) from the outlet of the casing to transport the cargo. This is the so-called plug transport).
ところで、前記空気輸送装置においてはケーシング内に
供給する高圧空気の気圧が大き過ぎても小さくても輸送
管内で輸送物が詰まるめで、この清掃が煩わしく、また
輸送終了の際、輸送物が輸送管内で栓状にふさぐ量が無
くなると、輸送物は搬送されることなく輸送管の底部に
残留するので、この残留物を除去するため別の高圧空気
供給装置によって多量の空気を吹き出す等、管路内の清
掃に手間取るという問題点があった。By the way, in the above-mentioned pneumatic transport device, if the pressure of the high-pressure air supplied into the casing is too high or too low, the transported goods will clog in the transport pipe, and this cleaning is troublesome. When there is no longer enough material to plug into a stopper, the transported material remains at the bottom of the transport pipe without being transported, so in order to remove this residue, a separate high-pressure air supply device is used to blow out a large amount of air, etc. There was a problem that it took time to clean the inside.
この発明は前記問題点を解決し、輸送物を輸送管内に残
留させることなく完全に排出することのできる粉粒体の
空気輸送装置を提供することを技術的課題とする。The technical object of the present invention is to solve the above-mentioned problems and provide a pneumatic transportation device for powder and granular materials that can completely discharge the transported materials without leaving them in the transportation pipe.
この発明は前記問題点を解決するため、輪、込物の供給
口と送出口とを設けたケーシング内に高圧空気を供給す
る送気管を臨ませ、供給口には輸送物を投入して密閉す
るための弁を設けた粉粒体の空気輸送装置において、前
記送出口に接続した輸送管の排出口部には、排出口から
吐出する空気を間歇的に制限する排出口間歇閉塞手段を
設けた、という技術的手段を講じた。In order to solve the above-mentioned problems, this invention places an air pipe for supplying high-pressure air inside a casing provided with a ring, a material supply port and a delivery port, and places the material to be transported into the supply port and seals it. In the air transportation device for powder and granular materials, the discharge port of the transport pipe connected to the outlet is provided with an outlet intermittent closing means for intermittently restricting the air discharged from the outlet. We took technical measures to
高圧空気によってケーシング内が高圧になると、ケーシ
ング内の輸送物は送出口から間隔を置いて脈動的にかつ
栓状に輸送管内に送り出され、輸送管の排出口から排出
されるのであるが、排出口部に設けた排出口間歇閉塞手
段によって排出口から排出する空気流が間歇的に制限さ
れるので、この制限時間を長短に調整することによって
排出口から排出する空気流が制限され、この制限時間を
長短に調整することによって輸送量を増減する。また、
ケーシング内に輸送物がなくなり輸送管内に栓状の塊を
形成できなくなったときにも、排出口を間歇的に閉塞す
ることで輸送管の輸送物は残留することなく排出する。When the pressure inside the casing becomes high due to high-pressure air, the transported material inside the casing is sent out into the transport pipe in a pulsating manner in the form of a plug at intervals from the delivery port, and is discharged from the discharge port of the transport pipe. Since the air flow discharged from the discharge port is intermittently restricted by the discharge port intermittent blocking means provided at the outlet, the air flow discharged from the discharge port is restricted by adjusting this limit time to a longer or shorter time. Increase or decrease the amount of transportation by adjusting the length of time. Also,
Even when there is no transport material in the casing and a plug-like mass cannot be formed in the transport pipe, the transport pipe is discharged without remaining by blocking the discharge port intermittently.

向けて移動する。Bran discharged from a rice milling machine (not shown) is conveyed to a supply hopper 7 by a flow conveyor or the like. The rotary valve 8 of this sharpening supply port 5 is open, and the bran falls onto the lower hopper 11 inside the casing 3. When a certain amount of bran accumulates in the casing 3, a signal is output from the level switch 10, which activates an air cylinder (not shown) that rotates the rotary valve shaft 9, rotates the rotary valve 8, and closes the supply port. 5. Close tightly. When the mechanical V-cylinder is activated and a position detection limit switch (not shown) is activated, this signal activates the solenoid valve 15 and high pressure air is supplied from the high pressure air generator 13 through the air pipe 12 into the casing 3. When high pressure air is supplied into the casing 3 and the inside of the casing 3 reaches a certain high pressure state, for example 5k (1/CTI'), a part of the bran in the casing 3 is transported from the outlet 6 by the high pressure air. It is pushed out like a plug into the tube 17 (B1
). When the bran is sent out to B1, the pressure inside the casing 3 decreases slightly, but since high-pressure air is supplied from the air pipe 12, the pressure inside the casing 3 decreases to 5ko/cm' again.
, and part of the bran is pushed out to 81 as before. At this time, the lump of bran that was previously at position B1 advances to B2, and in the same way, bran is pushed out in a plug-like manner from the outlet 6 into the transport pipe 17 in a pulsating manner, and from the inside of the transport pipe 17 to the discharge port 19a. move toward

輸送量（輸送速度）を決定する。Then, after a certain period of time, for example 2 seconds, the air cylinder 26 contracts and the closing plate 25 moves away from the outlet -9 = 19a, the pressure near the outlet 19a decreases rapidly, and the rice bran flows towards the outlet 19a again. begins to move. After that, for a certain period of time until the knee cylinder 26 extends,
For example, bran and air are discharged for 5 seconds, and thereafter, a closing time of 2 seconds and an opening time of 5 seconds are alternately performed. As a result, it was found that the amount of bran transported could be increased or decreased by adjusting the length of the opening time, and by setting the timer (not shown) of the air cylinder 26 provided on the control panel, the amount of bran transported could be increased or decreased depending on the cargo to be transported. Determine transport volume (transport speed).
