Description

本発明は粉体の供給添加装置、及び、該粉体の供給添加装置を用いた粉体の供給添加方法に関する。 The present invention relates to a powder supply/addition device and a powder supply/addition method using the powder supply/addition device.

粉体製品を輸送対象となる添加設備(ベルトコンベアやホッパー等)に添加する場合、従来、ポンプ(モーノポンプ)や空気圧送、バケットコンベア、ディスクコンベア等により移送していた。
しかしながら、ポンプや空気圧送により粉体を輸送する方法では、粉体輸送時に高流速粉体によってホース内面が摩耗(著しい場合はホースが破損)したり、該ホースの破損個所から粉体飛散などが起こったりすることがあり、適切な粉体製品の添加設備への添加が困難となることがあった。また、バケットコンベアは装置が大きいために設置スペースの確保が難しい場合が多く、ディスクコンベアでは高い位置に粉体を輸送することに適さないという問題があった。
When adding powdered products to the additive equipment (belt conveyor, hopper, etc.) that is being transported, conventionally the product is transferred using a pump (Mono pump), pneumatic transport, bucket conveyor, disc conveyor, etc.
However, with methods of transporting powder using pumps or air pressure, the high-velocity powder during powder transport can cause wear on the inner surface of the hose (in severe cases, the hose may be damaged), and the powder can be scattered from the damaged part of the hose. This can sometimes make it difficult to add the appropriate powder product to the addition equipment. Furthermore, since bucket conveyors are large devices, it is often difficult to secure installation space, and disk conveyors have the problem of not being suitable for transporting powder to high locations.

このような問題に対し、例えば、特許文献1には定量した添加粉末を、母材粉末に貫入されたスクリューフィーダーを通じて供給することで添加粉末の飛散を防ぐ技術が開示されている。
しかしながら、特許文献1に記載の方法では、母材粉末が間欠添加であり連続的な母材粉末の添加ができず、また、母材粉末を中間貯蔵部からホッパーまで移送する手段が開示されていない。
また、例えば、特許文献2には粉体の高所(又は離れた場所)への気流輸送の手段として圧送によるものと真空吸引によるものとがある旨が開示されている。
しかしながら、特許文献2に開示の技術は、ベルトコンベアやホッパー等に対して粉体を添加する手段は具体的に開示しておらず、また、真空吸引で粉体を輸送することの効果については何ら開示されていない。
To address this problem, for example, Patent Document 1 discloses a technique for preventing the scattering of the additive powder by supplying a fixed amount of the additive powder through a screw feeder penetrated into the base material powder.
However, in the method described in Patent Document 1, the base material powder is added intermittently and cannot be added continuously, and a means for transporting the base material powder from the intermediate storage section to the hopper is not disclosed. do not have.
Further, for example, Patent Document 2 discloses that there are two methods for airflow transport of powder to a high place (or a remote place): one using pressure feeding and the other using vacuum suction.
However, the technique disclosed in Patent Document 2 does not specifically disclose means for adding powder to a belt conveyor, hopper, etc., and does not specifically disclose the effect of transporting powder by vacuum suction. Nothing has been disclosed.

また、例えば、モーノポンプを使用して粉体製品を移送する方法や、コンベアを利用して粉体製品を移送する方法等も従来から検討されている。
しかしながら、モーノポンプを使用する方法は、粉体製品を高い位置にまで移送することができないため、添加装置を設置可能な場所の制約が多く、また、モーノポンプ停止時に粉体製品が移送される管内に残留して閉塞が生じやすいという問題もあった。
また、コンベアを利用する方法では、粉体製品を高い位置にまで移送することが難しく、また、設備が大型となり、添加装置を設置可能な場所の制約がより多くなるという問題があった。
Further, for example, a method of transporting a powder product using a Mono pump, a method of transporting a powder product using a conveyor, etc. have been studied in the past.
However, with the method of using a Mono pump, the powder product cannot be transferred to a high position, so there are many restrictions on where the addition device can be installed. There was also the problem that it remained and was likely to cause blockage.
Furthermore, in the method of using a conveyor, it is difficult to transport the powder product to a high position, and the equipment becomes large, which increases the number of restrictions on where the addition device can be installed.

そこで、本発明は、粉体を貯蔵した容器等から添加装置に輸送して被添加物に供給する際に、ホース等の供給部材に破損や閉塞が生じ難く、また、供給及び添加時の粉体飛散を効果的に防止でき、更に装置の設置場所の選択が自由な粉体の供給添加装置、及び、該粉体の供給添加装置を用いた粉体供給添加方法を提供することを課題とする。 Therefore, the present invention aims to prevent damage or blockage of supply members such as hoses when the powder is transported from a storage container etc. to an addition device and supplied to the additive, and to prevent the powder from being damaged or clogged during supply and addition. It is an object of the present invention to provide a powder supply/addition device which can effectively prevent powder scattering and which allows freedom in selecting the installation location of the device, and a powder supply/addition method using the powder supply/addition device. do.

本発明者らは、上記の課題を解決するために鋭意研究を重ねた結果、粉体を貯蔵する容器から供給対象物に粉体を供給する添加装置までは吸引手段を用いて粉体の供給を行い、添加装置から供給対象物へ連続かつ無圧力で粉体を添加することで、ホース等の供給部材の破損を防止し、かつ、供給及び添加時に粉体飛散を効果的に防止でき、更に装置の設置場所の選択が自由になることを見出し、本発明を完成するに至った。 As a result of extensive research in order to solve the above problems, the present inventors have discovered that a suction means is used to supply the powder from the container that stores the powder to the addition device that supplies the powder to the object to be supplied. By adding powder continuously and without pressure from the addition device to the object to be supplied, it is possible to prevent damage to supply members such as hoses, and to effectively prevent powder scattering during supply and addition. Furthermore, the inventors discovered that the installation location of the device can be freely selected, leading to the completion of the present invention.

(4) The present invention also provides a powder supply/addition method using the powder supply/addition device according to any one of (1) to (3).
The present invention will be explained in detail below.

図1は、本発明に係る粉体の供給添加装置の一例を示す模式図である。
図1に示したように、本発明の粉体の供給添加装置10は、粉体6を貯留する容器1と、添加対象物5に対して粉体6を添加する添加装置3と、容器1と添加装置3とを繋ぐ粉体輸送部材2とを備えている。
FIG. 1 is a schematic diagram showing an example of a powder supply/addition device according to the present invention.
As shown in FIG. 1, a powder supply/addition device 10 of the present invention includes a container 1 for storing powder 6, an addition device 3 for adding powder 6 to an addition target 5, and a container 1. and a powder transport member 2 that connects the and the addition device 3.

本発明に係る粉体の供給添加装置10は、粉体輸送部材2に吸引手段4が接続されており、粉体6は、吸引手段4により容器1から吸引され粉体輸送部材2を通って添加装置3に供給される。
粉体6が吸引により容器1から添加装置3に供給されることで、微粉が舞い難く周辺設備に悪影響を与え難くなる。
In the powder supply/addition device 10 according to the present invention, a suction means 4 is connected to the powder transport member 2, and the powder 6 is sucked from the container 1 by the suction means 4 and passed through the powder transport member 2. It is supplied to the addition device 3.
Since the powder 6 is supplied from the container 1 to the addition device 3 by suction, the fine powder is less likely to fly and adversely affect peripheral equipment.

吸引手段4としては特に限定されず、例えば、真空ポンプ、真空搬送装置、吸引式空気輸送装置、バキュームコンベア、吸引搬送システム等が挙げられる。
また、吸引手段4による粉体6の吸引の条件は、粉体6の種類、容器1と添加装置3との距離や粉体輸送部材2の材質及び耐久性等を考慮して適宜決定される。
The suction means 4 is not particularly limited, and includes, for example, a vacuum pump, a vacuum conveyance device, a suction type pneumatic conveyance device, a vacuum conveyor, a suction conveyance system, and the like.
Further, the conditions for suctioning the powder 6 by the suction means 4 are appropriately determined by taking into consideration the type of the powder 6, the distance between the container 1 and the addition device 3, the material and durability of the powder transport member 2, etc. .

容器1は、その内部に粉体6を貯蔵できるコンテナ等従来公知のものが挙げられるが、内部に貯蔵した粉体6の排出時の飛散を抑制でき、かつ、後述する粉体輸送部材2を接続できる部材を備えることが好ましい。
このような容器1としては、例えば、図1に示したように容器1は底が漏斗状で、該漏斗状の底の頂点に粉体6の排出口が設けられ、該排出口に取り付け治具が接続された構造が挙げられる。容器1の底が漏斗状であることで容器1内に供給した粉体6が自重で排出口から排出されるため容器1内での粉体6の飛散を抑制でき、かつ、無駄なく粉体6を容器1から排出させることができる。また、排出口に取り付け治具が接続されることで、粉体輸送部材2への接続が容易となる。
The container 1 can be a conventionally known container such as a container that can store the powder 6 therein, but it can suppress the scattering of the powder 6 stored inside when it is discharged, and can also be used as a powder transportation member 2 to be described later. It is preferable to include a member that can be connected.
For example, as shown in FIG. 1, the container 1 has a funnel-shaped bottom, and a discharge port for the powder 6 is provided at the apex of the funnel-shaped bottom. An example is a structure in which parts are connected. Since the bottom of the container 1 is funnel-shaped, the powder 6 supplied into the container 1 is discharged from the outlet under its own weight, so scattering of the powder 6 inside the container 1 can be suppressed, and the powder can be collected without waste. 6 can be discharged from the container 1. Furthermore, by connecting a mounting jig to the discharge port, connection to the powder transport member 2 becomes easy.

粉体輸送部材2は、容器1と添加装置3とを接続して粉体6を容器1から添加装置3に供給するための部材である。このような粉体輸送部材2としては、内部に粉体6を流通させることができる部材であれば特に限定されないが、配管等に用いられる剛直なパイプや、可撓性を有するホース等が挙げられる。 The powder transport member 2 is a member for connecting the container 1 and the addition device 3 and supplying the powder 6 from the container 1 to the addition device 3. Such a powder transport member 2 is not particularly limited as long as it is a member that can circulate the powder 6 inside, but examples include rigid pipes used for piping, flexible hoses, etc. It will be done.

上記パイプとしては剛直な材料からなる物が挙げられ、例えば、銅パイプ、ステンレススチールパイプ、合成樹脂パイプ等公知の材料からなるパイプが挙げられる。
また、上記ホースとしては可撓性を有するものであればよく、例えば、ゴム、熱可塑性エラストマー、熱可塑性樹脂等が挙げられる。
このような粉体輸送部材2は、内部を流通する粉体の種類や粉体が通過する際にかかる負荷等を考慮して適宜決定される。
なかでも、上記可撓性を有するホースであることが好ましい。粉体輸送部材2が可撓性を有することで、容器1と添加装置3との間に障害となる物が存在していても、該障害となる物を避けて粉体輸送部材2を配置できるため、既存の工場に容易に本発明に係る粉体の供給添加装置10を容易に設置することができる。また、可撓性を有することで内部を流通する粉体による破損を受けにくくすることもできる。
The above-mentioned pipes include those made of rigid materials, such as pipes made of known materials such as copper pipes, stainless steel pipes, and synthetic resin pipes.
Further, the hose may be made of any material having flexibility, such as rubber, thermoplastic elastomer, thermoplastic resin, etc.
Such a powder transport member 2 is appropriately determined in consideration of the type of powder flowing therein, the load applied when the powder passes, and the like.
Among these, the hose having the above-mentioned flexibility is preferable. Since the powder transport member 2 has flexibility, even if there is an obstacle between the container 1 and the addition device 3, the powder transport member 2 can be arranged to avoid the obstacle. Therefore, the powder supply/addition device 10 according to the present invention can be easily installed in an existing factory. Further, by having flexibility, it can be made less susceptible to damage by powder flowing inside.

可撓性を有する粉体輸送部材2としては、例えば、ゴム、熱可塑性エラストマー、熱可塑性樹脂等からなるホースが好適に用いられる。
本発明において、上記ホースの長さは本発明に係る粉体の供給添加装置を設置する工場のレイアウト等に応じて適宜決定すればよいが、上記ホースの長さは、例えば、5m以上であることが好ましい。上記ホースの長さが5m以上であることで、例えば、容器1を地上に設置した状態で添加装置3を添加対象物5の上部に配置することが容易となる。なお、実際に本発明に係る供給添加装置を設置する現場によっては、上記ホースの長さは5m未満であってもよい。
As the flexible powder transport member 2, for example, a hose made of rubber, thermoplastic elastomer, thermoplastic resin, etc. is suitably used.
In the present invention, the length of the hose may be appropriately determined depending on the layout of the factory in which the powder supply/addition device according to the present invention is installed, but the length of the hose may be, for example, 5 m or more. It is preferable. When the length of the hose is 5 m or more, for example, it becomes easy to arrange the addition device 3 above the addition target 5 while the container 1 is installed on the ground. Note that the length of the hose may be less than 5 m depending on the site where the supply/addition device according to the present invention is actually installed.

添加装置3は、容器1から粉体輸送部材2を通して供給された粉体6を添加対象物5に添加するための装置であり、連続かつ無圧力で添加対象物5に粉体6の添加ができる粉体添加手段を備える。
上記粉体添加手段としては連続かつ無圧力で添加対象物5に粉体6の添加ができる手段であれば特に限定されないが、例えば、スクリューフィーダー、ベルトコンベア、サークルフィーダ(登録商標)、ディスクコンベア等が挙げられる。なかでも、粉体6の飛散抑制をより効果的に行うことができることからスクリューフィーダーが好適である。
なお、「連続かつ無圧力」とは、添加される粉体6が、問題にならない程度で脈動や飛散しない状態で連続的に添加される条件であり、具体的には特に限定されないが、例えば、上記粉体添加手段がスクリューフィーダーの場合、回転数が10~100rpm程度であることが好ましいが、これに限定されるものではない。
The addition device 3 is a device for adding the powder 6 supplied from the container 1 through the powder transport member 2 to the addition target 5, and adds the powder 6 to the addition target 5 continuously and without pressure. Equipped with means for adding powder.
The powder addition means is not particularly limited as long as it can continuously and pressurelessly add the powder 6 to the addition target 5, but examples include a screw feeder, a belt conveyor, a circle feeder (registered trademark), and a disc conveyor. etc. Among these, a screw feeder is preferred because it can more effectively suppress scattering of the powder 6.
Note that "continuously and without pressure" is a condition in which the added powder 6 is added continuously without pulsation or scattering to an extent that does not cause problems, and is not specifically limited, but for example, When the powder adding means is a screw feeder, the rotation speed is preferably about 10 to 100 rpm, but is not limited thereto.

また、図示しないが、本発明に係る粉体の供給添加装置10は、添加対象物5の流量に応じて上記粉体供給手段の添加速度を制御する制御部を有することが好ましい。例えば、上記粉体供給手段がスクリューフィーダーである場合、上記制御部により添加対象物5の流量に応じてスクリューフィーダーのスクリューの回転数を制御することで、粉体6の添加量を調整することができ、連続的な粉体6の添加が可能となる。 Further, although not shown, it is preferable that the powder supply/addition device 10 according to the present invention includes a control section that controls the addition speed of the powder supply means according to the flow rate of the addition target material 5. For example, when the powder supply means is a screw feeder, the amount of powder 6 to be added can be adjusted by controlling the rotation speed of the screw of the screw feeder according to the flow rate of the substance to be added 5 by the control section. This makes it possible to continuously add the powder 6.

上記粉体供給手段を備えた添加装置3は、添加対象物5の上部に配置されていることが好ましい。既存の工場内に本発明に係る粉体の供給添加装置10を設置する場合、設置スペースの確保が難しい場合が多いが、添加装置3が添加対象物5の上部に配置されることでスペースの確保が容易となり、また、連続的かつ無圧力で添加される粉体6の自然落下を利用して添加対象物5に粉体6を添加できるので、粉体6の飛散をより効果的に抑制できる。 It is preferable that the addition device 3 equipped with the powder supply means is placed above the object 5 to be added. When installing the powder supply/addition device 10 according to the present invention in an existing factory, it is often difficult to secure the installation space. It is easier to secure the powder 6, and the powder 6 can be added to the addition target 5 by utilizing the natural fall of the powder 6 that is added continuously and without pressure, so scattering of the powder 6 can be suppressed more effectively. can.

本発明に係る粉体の供給添加装置10において、粉体6としては特に限定されないが、例えば、粒子径が1~1000μm程度の粉体が好適に用いられ、このような粉体としては、具体的には、凝集剤、吸水性樹脂、分散剤等の高分子粉末、炭酸カルシウム粉末、酸化カルシウム粉末、酸化マグネシウム粉末等の無機粉末等が挙げられる。なお、粉体6の粒子径はより好ましい下限は100μm、より好ましい上限は500μmである。
また、上記粉体6が添加される添加対象物5としては、例えば、石炭、コークス、鉄鉱石、バイオマス燃料等の粉体や、食品、機械、プラスチック製品等の工業製品等任意の物が挙げられる。
In the powder supply/addition device 10 according to the present invention, the powder 6 is not particularly limited, but for example, a powder having a particle size of about 1 to 1000 μm is suitably used. Examples include polymer powders such as flocculants, water-absorbing resins, and dispersants, and inorganic powders such as calcium carbonate powder, calcium oxide powder, and magnesium oxide powder. In addition, the particle diameter of the powder 6 has a more preferable lower limit of 100 μm, and a more preferable upper limit of 500 μm.
Further, examples of the additive object 5 to which the powder 6 is added include powders such as coal, coke, iron ore, and biomass fuel, and arbitrary materials such as industrial products such as foods, machinery, and plastic products. It will be done.

このような添加対象物5は、例えば、ベルトコンベア等の移動装置7上に載置され移動し、添加装置3の下にきたときに粉体6が添加される。
図1に示したように、添加対象物5が粉体であって、移動装置7上に幅広く載置されている場合や、添加対象物5が大きな工業製品であるような場合、粉体6を均一に添加対象物5に添加させるため、添加装置3は、添加対象物5の幅方向に移動するように配置してもよく、複数の添加装置3を添加対象物5の幅方向に並べて配置してもよい。
Such an addition target 5 is placed and moved on a moving device 7 such as a belt conveyor, and when it comes below the addition device 3, the powder 6 is added thereto.
As shown in FIG. 1, when the addition target 5 is a powder and is widely placed on the moving device 7, or when the addition target 5 is a large industrial product, the powder 6 In order to uniformly add to the addition object 5, the addition device 3 may be arranged so as to move in the width direction of the addition object 5, or a plurality of addition devices 3 may be arranged in the width direction of the addition object 5. May be placed.

本発明に係る粉体の供給添加装置10は、上述した構成からなるため、ホース等の供給部材の破損を防止し、かつ、供給及び添加時に粉体飛散を効果的に防止でき、更に装置の設置場所の選択が自由にすることができる。
このような本発明に係る粉体の供給添加装置を用いた粉体の供給添加方法もまた、本発明の一つである。
Since the powder supply/addition device 10 according to the present invention has the above-described configuration, it can prevent damage to supply members such as hoses, effectively prevent powder scattering during supply and addition, and furthermore, can prevent the powder from scattering during supply and addition. The installation location can be freely selected.
A powder supply/addition method using the powder supply/addition device according to the present invention is also one of the present inventions.

本発明の粉体の供給添加方法は、上述した粉体の供給添加装置を用いるため、移送時の粉体の飛散及びホース等の部材の破損を抑制でき、添加装置を添加対象物の上部に配置することも容易であるため、既存の工場に対しても好適に適用できる。
一方、容器から添加装置までの粉体の移送を空気圧送により行うと、粉体に圧力がかかった状態で移送されるため装置の周囲に粉体の飛散が防止できず、また、容器と添加装置とを繋ぐホース等の部材に大きな圧力がかかるため、ホースの抜けや破れが生じる危険性がある。
更に、容器から添加装置までの粉体の移送をモーノポンプにより行うと、高い位置への粉体の移送が難しく、添加装置を添加対象物の上部に設置することができないため、装置の設置場所に制限がかかり、また、モーノポンプ停止時に粉体がホース内に残りやすく閉塞が生じる危険性がある。
Since the powder supply/addition method of the present invention uses the powder supply/addition device described above, it is possible to suppress scattering of the powder during transfer and damage to members such as hoses, and the addition device is placed above the object to be added. Since it is easy to arrange, it can also be suitably applied to existing factories.
On the other hand, if the powder is transferred from the container to the addition device using air pressure, the powder is transferred under pressure, making it impossible to prevent the powder from scattering around the device. Because a large amount of pressure is applied to the hoses and other members that connect the equipment, there is a risk that the hoses will come off or break.
Furthermore, if the powder is transferred from the container to the addition device using a mono pump, it is difficult to transfer the powder to a high position, and the addition device cannot be installed above the object to be added. In addition, there is a risk that powder may remain in the hose when the Mono pump is stopped, causing blockage.

本発明の粉体の供給添加装置によると、ホース等の供給部材の破損を防止し、かつ、供給及び添加時に粉体飛散を効果的に防止でき、更に装置の設置場所の選択が自由にすることができる。 According to the powder supply/addition device of the present invention, damage to supply members such as hoses can be prevented, powder scattering can be effectively prevented during supply and addition, and the installation location of the device can be freely selected. be able to.
