【発明の詳細な説明】
この発明は輸送管が粉粒体により閉塞しかかつ
た際、直ちにこれを解除すると共に正常輸送状態
への復帰を迅速にしうるものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of immediately releasing the blockage of a transport pipe when it is about to be clogged with powder and granules, and quickly returning to a normal transport state.
輸送管の閉塞は輸送開始直後に起こるが輸送中
にも起こる。 Blockage of transport pipes occurs immediately after the start of transport, but also occurs during transport.
而して輸送開始直後の閉塞は適当な輸送開始条
件を設定することによつて予防又は回避できるが
輸送中の閉塞は予測不能であり閉塞生成を検知し
うるのみである。 Although blockage immediately after the start of transportation can be prevented or avoided by setting appropriate transportation start conditions, blockage during transportation is unpredictable and only the occurrence of the blockage can be detected.
本出願人は、先に閉塞解除方法として輸送管又

きない。 The present applicant has previously disclosed that it is effective to reduce the pressurized gas when the pressure of the transport pipe or tank increases, and conversely increase the amount of gas supplied to the transport pipe, as a method for releasing the blockage. (Japanese Unexamined Patent Publication No. 52-126881) Although the above method and device remove the blockage, since the booster valve is opened, a large amount of gas flows into the transport pipe after the blockage is removed, resulting in a pressure loss. As a result, the pressure inside the pipe does not fall to normal pressure, so it is impossible to know from the outside whether the normal state has been restored or not, that is, whether the blockage has been completely released.
更に粉粒体送給端が気体流入量に制限がある場
合は適用不可能である。 Furthermore, it is not applicable when there is a limit to the amount of gas flowing into the powder or granular material feeding end.
本発明は上記の欠点を解消するための改良装置

所期の目的を達成しうるものである。 The present invention provides an improved device for eliminating the above-mentioned drawbacks, and is capable of achieving the intended purpose despite its simple configuration.
即ち、本発明は、共通の供給本管から分岐され

のである。 That is, the present invention provides a transport device having a pressurization line and a booster line that are branched from a common supply main, while simultaneously adjusting the control valve 9 of the pressurization line based on the output of a tank internal pressure detector. The booster valve 10 is configured to adjust the flow rate so that the flow rate is always constant regardless of the above adjustment.

is connected to. 6 is a pressurized gas supply source, and the pressurized gas is branched from the main supply pipe 12 into a pressurizing line 7 and a booster line 8. 9 is
This is a pressurized gas regulating valve installed in the pressurizing line 7, and is operated by the output of the pressure regulator 16 into which the detected output of the tank pressure detector 15 is input.
即ち、タンク内圧力が減少して粉粒体切り出し

インに介装されたブスター気体調節弁であつて、
供給本管１２に介装された流量検出器１８と流量
調節計１９により供給本管の流量が常時一定にな
るように操作されている。 That is, when the internal pressure in the tank decreases and the amount of powder cut out decreases, the opening degree is increased to increase the amount of gas inflow, and when the transport pipe is about to become clogged due to excessive supply of powder or other reasons, Since the pressure increases, in this case, the opening degree is narrowed to reduce the tank pressure. 10 is a booster gas control valve installed in the booster line,
A flow rate detector 18 and a flow rate controller 19 interposed in the supply main pipe 12 are operated so that the flow rate of the supply main pipe is always constant.
上記輸送装置によつて粉粒体が輸送されている

ク内圧力は上昇するから加圧気体調節弁９の開度
は絞られてその供給量は減少せしめられる。 If a blockage or stagnation occurs in the transport pipe when powder or granular material is being transported by the above-mentioned transport device, the pressure inside the tank will increase, so the opening degree of the pressurized gas control valve 9 will be throttled and the supply amount will be reduced. be reduced.
これに伴なつて、供給本管の気体流量も減少し
ようとするが、流量調節計１９の作動により供給
本管の流量が変化しないようにブスター弁１０が
操作されてブスター流量が増加せしめられる。 Along with this, the gas flow rate in the supply main pipe also tends to decrease, but the booster valve 10 is operated to increase the booster flow rate so that the flow rate in the supply main pipe does not change due to the operation of the flow rate controller 19.

い利点がある他、粉粒体の供給量も閉塞の前後を
通じて平均化され正常輸送量とほぼ同様になる。 By increasing the booster flow rate, the solid-air ratio in the transport pipe decreases and the blockage is released. In the present invention,
Since the gas flow rate in the transport pipe does not change over time before and after the blockage is removed, there is an advantage that the condition at the supply end is not disturbed, and the supply amount of powder and granular material is also averaged before and after the blockage, making it almost the same as the normal transport amount. Become.
更に輸送管内の流量が閉塞に関係なく一定であ
るから閉塞解除により輸送管圧力は直ちに正常圧
力に復帰し、この状態はタンク圧力検出器１５に
よつて容易に検知できるのである。 Furthermore, since the flow rate in the transport pipe is constant regardless of the blockage, the pressure in the transport pipe immediately returns to normal pressure upon release of the blockage, and this state can be easily detected by the tank pressure detector 15.
以上の通り本発明は閉塞解除をそれに必要な最
小限の気体量増加で行ない、更に輸送管内の気体

行なわれる等の効果を有するものである。 As described above, the present invention removes the blockage with a minimum increase in the amount of gas necessary for the removal, and furthermore, the gas flow rate in the transport pipe does not change before and after removing the blockage, so the state of release can be reliably known and normality can be restored quickly. It has the effect of
